【先前技術】 傳統的斜斷鋸做為一種切割工具，具備廣泛的應用範 圍，可以用於切割金屬或非金屬材料，而快捷方便地進行切 割。斜斷鑛-般包括工作臺、位於卫作臺上方具有電動機和 圓鋸片的鋸機構、以及連接工作臺和鋸機構的轉角支架其 中鋸機構圍繞與工作臺相對固定的一樞軸而可旋轉地與工作 臺配接，並用以進行工件切割之作業。 傳統斜斷鋸的鋸切工作主要是：操作者首先將工件要切 斷的部位畫好切割標記線後，進行對刀，也就是在接通電源 前，壓下鋸機構，移動被切割工件，使得被切割工件上的切 割標記線對準圆鋸片；如此，當接通電源後，圓鋸片在電動 機的驅動下高速旋轉，就可以將工件切成操作者想要的尺 寸。但是由於操作者係透過肉眼觀察圓鋸片與切割標記線的 對準情況，再加上錯片具一定的厚度，所以很難做到圓鑛片 201012576 與切割標記線對準，而且還要壓下鋸機構再能進行對刀比 較麻煩。 因此斜斷鋸通常會再設置一雷射對準裝置，該雷射對準 裝置可以在工件表面上投射出一道雷射光束，如此可讓操作 者非常清楚地知道該圓鋸片的下刀位置，而可較輕鬆地移動 工件’使其上的切割標記線對準圓鋸片，就可以將工件準確 瘳 地切割成操作者想要的尺寸。 美國第6481322號專利公開了一種斜斷鑛，該斜斷錯 包括工作臺、位於工作臺的上方具有電動機和圓鋸片的鋸 機構、以及連接工作臺和鑛機構的轉角支架，其中鑛機構 包括用於與轉角支架連接的支臂。在該支臂上安裝有雷射 對準裝置，該雷射對準裝置可以在工件表面上投射出一道 雷射光束，如此可讓操作者非常清楚地知道該圓鋸片的下 Θ 刀位置，而將工件準確地切成操作者想要的尺寸。但是由 於斜斷鋸在切割過程中會產生很多鋸屑，而且這些鋸屑會 到處飛濺，如果雷射對準裝置被這些鋸屑吸附，就會使得 投射出的雷射光束愈來愈黯淡，並影響到操作者的觀察， 使得操作者很難精確地將工件與投射出的雷射光束對準； 嚴重時，雷射對準裝置投射出的雷射光束會遭到遮蔽，使 得操作者無法方便、快捷地進行切割作業。 201012576 【發明内容】 置清 本發明之目的在於提供一種可以保持雷射對 潔的斜斷鋸。 ❹ 本發明之另一目的在於提供一 束的斜斷鋸 種可以精確投射雷射光 為達成上述之目的，本發明之斜_具有—切割區域， 而於該切割區域中進行工件切割作業，本發明之斜_包含 有 一基座，係用以支撐被切割的工件； 支撑裝置’以與上述基座配接； 一鋸機構，係與支撐裝置通過樞轴旋轉連接，該鋸機構 包含有與支撑裝置樞轴連結的固定護罩、固定連結在 固疋濩罩上的電動機、與由電動機旋轉驅動的圓鑛 片，該鑛機構圍繞前述框轴而於休止位置和工作位置 之間旋轉切換’於該休止位置時，鋸機構處於自由狀 態，於工作位置時，圓鑛片進行工件切割作業；以及 201012576 一雷射對準裝置，該雷射對準裝置產生 一雷射光束，投 - 射至該工作平臺上形成一道對準線，用於在被切割的 工件上與對準線進行定位對準； 其特徵在於：在該鋸機構圍繞該樞轴旋轉過程中，該雷 射對準裝置相對於鑛機構和該支撐裝置都產生相對應的運 動。 ❹ 較佳地’於休止位置時’該雷射光束投射在該切割區域 内〇 較佳地’於工作位置時，該雷射光束離開該切割區域。 該雷射對準裝置通過連接裝置至少與該固定護罩和支撐 裝置之一連接。 Ο 其中’該雷射對準裝置包含有發射雷射光束的雷射發生 器和用來支撑雷射發生器的支撐座，該支撐座安裝在該連接 裝置上。 於工作位置時，該雷射發生器係朝向著該支撐裝置。 較佳地’該連接裝置為一集塵裝置，且該集塵裝置包含 201012576 - 有一個集塵通道。 其中’該雷射對準裝置係與該集塵通道分隔開。 其中，該集塵裳置包含有一對側壁和一端壁，該等側壁 與該端壁形成該集塵通道。 〇 該端壁具有一供鋸屑排出的内表面，以及相對設置的外 表面’而該雷射對準裝置係設置於該端壁的該外表面上。 該集塵裝置係與該固定護罩互相樞接。 該集塵裝置與該固定護罩係經由一連接桿樞接。 ❹ 該連接桿的一端通過一第一枢軸與該集塵管道連接，而 其另一端與該固定護罩活動連接。 該集塵管道與該支撐裝置通過一第二樞軸固定樞接，且 該第一樞軸與該第二樞轴係呈不同軸設置。 該集塵裝置與雷射對準裝置圍繞該第二樞轴柩轉，於工 作位置時’集塵通道與固定護罩形成了該集塵管道而該雷 射對準裝置與該集塵管道係分隔開。 201012576 一雷射對準裝置，該[Prior Art] As a cutting tool, the traditional miter saw has a wide range of applications and can be used for cutting metal or non-metal materials for quick and easy cutting. A slanting ore mine generally includes a table, a saw mechanism having a motor and a circular saw blade above the guard table, and a corner bracket connecting the table and the saw mechanism, wherein the saw mechanism is rotatable about a pivot fixed relative to the table The ground is mated with the workbench and used for workpiece cutting operations. The sawing work of the traditional miter saw is mainly: the operator first draws the cutting mark line on the part to be cut, and then performs the tool setting, that is, before the power is turned on, the saw mechanism is pressed and the workpiece to be cut is moved. The cutting mark line on the workpiece to be cut is aligned with the circular saw blade; thus, when the power is turned on, the circular saw blade is rotated at a high speed under the driving of the motor, and the workpiece can be cut into a size desired by the operator. However, since the operator observes the alignment of the circular saw blade and the cutting mark line by the naked eye, and adds a certain thickness to the wrong piece, it is difficult to align the ore piece 201012576 with the cutting mark line, and it is also pressed. It is more troublesome for the lower saw mechanism to perform the tool setting. Therefore, the miter saw usually has a laser alignment device that can project a laser beam on the surface of the workpiece, so that the operator can clearly know the lower blade position of the circular saw blade. By moving the workpiece more easily 'aligning the cutting mark line on the circular saw blade, the workpiece can be accurately cut to the size desired by the operator. U.S. Patent No. 6,481,322 discloses a oblique breakage comprising a table, a saw mechanism having an electric motor and a circular saw blade above the table, and a corner bracket connecting the table and the mining mechanism, wherein the mining mechanism includes An arm for connection to a corner bracket. A laser alignment device is mounted on the arm, and the laser alignment device can project a laser beam on the surface of the workpiece, so that the operator can clearly know the position of the lower blade of the circular saw blade. The workpiece is accurately cut to the size desired by the operator. However, since the miter saw will produce a lot of sawdust during the cutting process, and the sawdust will splash everywhere, if the laser alignment device is adsorbed by the sawdust, the projected laser beam will become more and more dim and affect the operation. The observation makes it difficult for the operator to accurately align the workpiece with the projected laser beam; in severe cases, the laser beam projected by the laser aligning device is shielded, making it impossible for the operator to conveniently and quickly. Perform cutting operations. 201012576 SUMMARY OF THE INVENTION The purpose of the present invention is to provide a miter saw that can keep the laser clean.另一 Another object of the present invention is to provide a bundle of oblique saw species capable of accurately projecting laser light for the above-mentioned purposes, the oblique_having-cutting region of the present invention, and performing a workpiece cutting operation in the cutting region, the present invention The slanting _ includes a base for supporting the workpiece to be cut; the supporting device 'to be mated with the pedestal; the sawing mechanism is pivotally connected to the supporting device, and the sawing mechanism includes the supporting device a pivotally connected fixed shield, an electric motor fixedly coupled to the solid cover, and a round ore piece driven by the motor, the ore mechanism rotating between the rest position and the working position around the frame shaft In the rest position, the saw mechanism is in a free state, in the working position, the round ore piece performs the workpiece cutting operation; and the 201012576 laser alignment device generates a laser beam, which is projected to the work.

The fixed shield 33 is generally affixed to the motor 36 for covering a portion of the circular saw blade 31, and the movable shield 34 is hinged to the fixed shield 33 for covering the remaining circular saw blade 31 in the rest position, and is movable The shroud 34 can be rotated relative to the fixed shroud 33 to expose the circular saw blade μ for cutting the workpiece. The miter saw has a cutting area for cutting a workpiece, and the cutting area is an area in which the ore 31 can cut the workpiece. As shown in the second figure, the movable shield 34 is coupled to the movable shield driving device 8 for quickly opening and closing the movable shield 34. The fixed shroud 33 is coupled to the support device 4 via a pivot 3〇 such that the operating handle pivots the saw mechanism 〇 3 to perform the cutting operation. The movable shield drive unit 8 includes a connector member. In the present embodiment, the connector member is a link 8 and, in addition, the connector member may be replaced with other rigid or interchangeable members. The outer side of the movable guard $34 is connected to one end of the link 81, and the left side is pivotally connected by a pin (not shown) which is disposed in parallel with the saw blade shaft 32. 12 201012576 The other end of the connecting rod 81 is connected with a fitting member 83 for connecting the connecting rod 81 and the branch device 4, wherein the _ end of the engaging member 83 is pivotally connected to the connecting rod 81 through the first pin 86.

The first pin 86 is located in the groove 82 and can slide in the groove 82. The groove 82 is arranged to have a certain length so as to facilitate the saw mechanism 3 not to pivot. Manually open the movable shield 34. In order to prevent the link 81 from interfering with the connecting portion 35 of the motor 36 (not shown) and the circular saw blade 31, the link 81 here is provided to have an arcuate curved 'bend degree" depending on the motor 36 and the circular saw blade 31. The size of the connecting portion 35 is determined as follows: > As shown in the second figure, the tilting saw 00 is in the rest position. If it is necessary to switch from the rest position to the working position, the operator 13 201012576 'the corpse, The handle (not shown) needs to be pressed. At this time, the pivot 30 rotates counterclockwise to drive the second gear 85 to rotate counterclockwise, and the first gear 84 coupled with the second gear 85 rotates clockwise to drive the link 81 to pull. The shield % rotates clockwise, and the movable shield 34 is opened to expose the ore teeth 311 (as shown in the fifth figure) to cut the workpiece 2 when the saw mechanism 3 is switched from the working position to the rest position 'Pivot 30 Turning clockwise 'drives the second gear 85 clockwise, and the first gear that rotates with the second gear 85 rotates counterclockwise, causing the link 81 to rotate counterclockwise by pulling the movable shield 34, thereby closing the movable shield 34, Protect the suture teeth 31 to meet safety standards. In order to quickly open and close the movable shield 34, the second gear 85 has a larger diameter than the first gear 84. As shown in the first and second figures, in order to facilitate the cutting of the workpiece, the oblique alignment 100 is further provided with a laser alignment device 5. The laser aligning device 5 can generate a laser beam 5 which is projected onto the table 2 or the workpiece to form an alignment line 52 (only the projection is projected onto the workpiece) for The cutting mark line 210 on the cut workpiece 200 is aligned with the alignment line 52. As in the second figure, the laser alignment device 5 includes a laser generator 53 that emits the laser beam 51, and is used to support The support base 54 of the laser generator 53. As is well known to those skilled in the art, the laser alignment device 5 also includes a power source and a switch. 14 201012576 Since the miter saw 100 produces a lot of sawdust during the cutting process and some of the swarf will splash around, the sawdust will stick to the laser aligning device 5, smudging the laser aligning device 5, thus affecting Reliability of alignment. Therefore, the laser alignment device 5 can be pivotally mounted to the fixed shield 33 or the support device 4, even on the work table 2, by means of a connection device. In the rest position, the laser beam 51 emitted by the laser alignment device 5 is projected in the cutting area to facilitate alignment by the operator; and in the cutting position, the laser alignment device 5 can be pivoted. It is separated from the sawdust that is splashed around so that the laser alignment device 5 can be kept clean. The connecting device in this embodiment is a dust collecting device 6, and the connecting device can be replaced by other rigid or flexible connecting members. The dust collecting device 6 can be at least mated with one of the fixed shroud 33 and the supporting device 4. In the present embodiment, the dust collecting device 6 is mated with the saw mechanism 3 and the supporting device 4, respectively. As shown in the first figure, the dust collecting device 6 includes a pair of side walls 61 and an end wall 62. The side walls 61 are substantially fan-shaped, and are of course designed in other shapes as needed. For effective dust guiding, the end wall 62 Also has a certain degree of curvature. The side walls 61 and the end wall 62 form a dust collecting passage 63. Here, the dust collecting passage 63 is not a sealed pipe. 15 201012576 As shown in the eighth and ninth, in the working position, the dust collecting passage 63 forms a dust collecting duct 64 with the fixed shroud 33, which collects and discharges sawdust. Since the saw blade and dust generated by the cutting workpiece 200 during the rotation of the circular saw blade 31, it moves along the flow direction 39 shown in the eighth figure. Thus, cutting debris and dust will be directed into the dust collecting duct 64' and then discharged into the dust collecting bag by the dust exhaust port 37 on the fixed shield 33. Referring again to the first and third figures, the dust collecting device 6 also has an inner surface 67 through which sawdust passes, and an oppositely disposed outer surface 68. The support base 54 is mounted on the outer surface (10) of the dust collecting device 6, and is spaced apart from the dust collecting passage 63 and the dust collecting duct 64. As shown in the third figure, the dust collecting slit 6 is pivotally connected to the fixed shield 33 via a connecting rod 7.一端 One end of the connecting rod 7 is movably connected to the dust collecting duct 6 via the first - ec Λ, ΛΕ * 柩 shaft 65, and the other end is movably connected to the fixed shroud 33. The fixed shield 33 is provided with a material 331. The connecting rod has a sliding slot 71'. The locking shaft 331 is accommodated in the sliding raft and can slide relative to the sliding slot 71. 4 # As shown in the second figure, the dust collecting duct 6 and the supporting device 4 are fixedly framed via the second frame 16 201012576, and the second shaft 66 is fixed relative to the supporting device 4 to the second shaft 65 and the second. Pivot 66 is a different shaft arrangement. Referring to the second figure, the vertical device 4 includes a first thrust member 41 mated with the table 2 and a meshing mechanism 3 with the mine machine. The second support member 42 » the first 支 support member 41 defines a longitudinal axis 4 * ί» η - loose. And the first support member 41 can be around the longitudinal axis 43 relative to the table 2, 丨β find force 丄l+ Rotate in both the hour and counterclockwise directions to tilt the angle for cutting the workpiece 200. A locking mechanism 44 is provided between the first support member 4 and the work table 2 to lock the first-out support member 4 to the table 2. The first frequency member 与 - the (10) τ dust removing device 6 and the second branch member 42 are fixedly framed by the first frame shaft 66. As shown in the second and tenth views, the second web 42 is movable relative to the first index member 41 / Q in the direction of the longitudinal axis 43 and stapled the cutting operation upon reaching a predetermined number of working positions. This can improve the cutting ability of the oblique mine, so that the oblique silver (10) can cut more specifications. The different positions of the workpiece in advance S are the maximum allowable cuts. 17 201012576 * The specifications correspond to each other. The maximum allowable cutting specifications of the workpiece include the maximum allowable dimension of the workpiece in the direction of the longitudinal axis 43 (that is, the width of the workpiece), or the maximum allowable dimension in the direction perpendicular to the longitudinal axis 43 (that is, the height of the workpiece). ). The miter saw 100 includes an indicating mechanism 9 for indicating the predetermined working positions. As shown in the third figure, the indicating mechanism 9 includes a working position mark 91 provided on the first supporting member 41, and an indicating mark 92 provided on the second supporting member 42, when the second supporting member 42 is moved to the corresponding In the working position, the indicator mark 92 is aligned with the work position mark 91. Of course, the work position mark can also be provided on the second support member 42, and the indicator mark matched thereto is disposed on the first support member 41. The plurality of predetermined working positions are sequentially arranged in a direction parallel to the longitudinal axis. In the embodiment, the miter saw has three working positions, and of course, more or more may be provided as needed. Less cutting position. As shown in the second figure, the work position mark 91 includes first and second work position marks 911, 912, 913. The first support member 4 and the second support member 5 can each be made of an iron-based material such as cast iron or Ferrous alloys, etc. The use of iron-based materials increases rigidity while reducing costs. 18 201012576 The first support member 41 and the second support member 42 may be integrally formed as in the case of a conventional miter saw. Before the miter saw is shipped from the factory, the alignment line 52 emitted by the laser generator 5 needs to be calibrated and kept at the same parallelism with the circular saw blade 31, so that the operator can obtain accurate indication effect during use, so The support base 54 is designed to be adjustable relative to the dust collecting device 6, or the laser generator 53 can be adjusted relative to the support base 54. It is of course also possible to adjust the position of the dust collecting device 6 relative to the fixed shroud 33 or the supporting device 4 such that the alignment line 52 emitted by the laser generator 53 is kept at the same parallelism as the circular saw blade 31. As shown in the third figure, the miter saw 100 is in the rest position, and the indicator mark 92 is aligned with the first work position mark 911, which is in the first working position determined by the pre ® . At this point, the switch of the laser alignment device 5 is turned on, and the laser alignment device 5 produces a laser beam 51 which is projected into the cutting area, i.e., onto the workpiece 200 being cut. The laser beam 51 is projected onto the workpiece 2 to form an alignment line 52' so that the operator can move the workpiece to be cut, and the cutting mark line 210 on the alignment line aligns with the alignment line 52, so that the operator can Precisely cut the workpiece. 19 201012576 • The receiver, as shown in the TO ISi k - spears, presses the saw mechanism 3 so that it rotates clockwise around the pivot axis. The mechanism 3 rotates clockwise to connect the mechanism 3 and dust. The connecting rod 7 of position 6 causes the dust collecting device 6 to rotate clockwise around the first pivot 66 (as shown in the second figure), while the dust collecting device 6 also drives the laser alignment device 5 to rotate clockwise. . Pressing the mine mechanism 3 to continue to rotate clockwise, as shown in the fifth to the second figure. At this time, the movable shield 34 is opened by the movable shield driving device 8, and the saw blade teeth 311 are cut out for cutting. The workpiece 200 » the dust collecting device 6 drives the laser alignment device 5 to continue to rotate clockwise around the second habitat 66, while the projection direction of the laser beam 51 generated by the laser alignment device 5 is gradually increased during the rotation. Leave the cutting area. The saw mechanism 3 is continuously pressed until the end wall 62 of the dust collecting device 6 is in contact with a point on the supporting device 4, as indicated by the sixth to seventh circles, at which time the dust collecting device 6 has reached the lowest limit position. The dust collecting passage 63 of the dust device 6 and the inlet of the dust collecting duct 64 formed by the solid shroud 33 are close to the table 2', and the closer to the table, the more sawdust can be collected. At the same time, after the laser alignment device 5 is pivoted, since the laser emitter has been directed toward the support device 4, if the laser switch is not turned off, the laser beam generated by the laser light aligning device 5 at this time The 51 has completely left the cutting area, so that the laser beam 51 can be prevented from continuing to project to the operator. If the succession is pressed at this time! In the wrong mechanism 3, the pin 331 on the fixed shield can slide in the chute 71, so that the saw mechanism 3 continues to press down to achieve the purpose of cutting. 20 201012576 ❺ The saw mechanism 3 continues to rotate clockwise to reach the cutting position, as shown in the eighth to ninth diagrams. At this time, the ore 31 rotates rapidly under the motor % collection to cut the workpiece 2〇〇. The dust collecting passage and the fixed shroud 33 form a dust collecting duct 64. Further, the dust generated by the circular saw blade 31 during the cutting process and the dust move along the flow square (9) shown in the eighth figure and are guided into the dust collecting duct 64, and then discharged into the dust collecting bag by the dust exhaust port 37. After the laser alignment device 5 is pivoted, since the laser generator has been completely separated from the dust collecting duct 64 toward the branching device 4', it is not adsorbed by the flying shoulders, so that it can be maintained. The laser is aligned with the cleaning of the device 5. As shown in the tenth figure, at this time, the second support member 42 is moved in the direction of the longitudinal axis 43 with respect to the first support member 41, so that the indicator mark 92 is opposite to the third working position mark 913, and the oblique saw 1〇〇 In a predetermined third working position. The difference from the first working position is that as the saw mechanism 3 rotates clockwise around the pivot 30, the dust collecting device 6 is caused to drive the laser alignment φ device 5 together with the second pivot 66 (such as the third figure) Shown) Turn clockwise; continue to press the saw mechanism 3 until the end wall 62 of the dust collecting device 6 comes into contact with the table, at which point the dust collecting device 6 has reached the lowest limit position. Thus, the dust collecting passage 63 of the dust collecting device δ and the inlet of the dust collecting duct 64 formed by the fixed shroud 33 are brought into contact with the table and located at the cutting groove 21. In this way, more sawdust can be collected. After the cutting is completed, as shown in Fig. 3, the mining mechanism 3 quickly returns to the rest position under the action of the reset bullet (not shown). During this process, the fixed guard 21 201012576 33171 slides until the pin shaft is in contact with the sliding top end, as shown in the sixth figure. At this time, the dust collecting device 6 is equipped with the laser beam aligning device 5 to drive around the first handle. @Rotate counterclockwise around the first cymbal 66, such as the fifth ❿ until the end wall 62 of the device 4 is in contact with the cutting device 4, at which point the dust collecting device 6 reaches the highest extreme position, the laser 'quasi device 5 The resulting laser beam 51 is projected in the cutting area, that is to say on the workpiece 2 to be cut. The laser beam 51 is projected onto the workpiece _ to form the trajectory alignment line 52, so that the operator can move the cut, and the member 200' is aligned with the alignment mark (4) to allow the operator to be precise. Cutting the workpiece. Thus, in the rest position, the laser beam emitted by the aligning device is projected into the cutting area to facilitate alignment by the operator; and when the position is cut, the laser aligning device can be twirled to collect dust The pipes are separated so that the sawdust that splashes around can be prevented from sticking to each other, so that the laser alignment device can be kept clean. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application in accordance with the law. However, the above-mentioned embodiments are merely preferred embodiments of the present invention, and equivalent modifications or variations made by those skilled in the art in the light of the present invention are included in the scope of the appended claims. 22 201012576 - [Simple description of the drawings] The first figure is the three-dimensional circle of the miter saw of the present invention, and the saw mechanism is in the rest position.
