Description of the Invention: [Technical Field] The present invention relates to a ball screw applied to a linear drive, in particular to a reflow device for the outer surface of a nut that is fitted with a screw, and the screw and the nut are The rolling elements can be combined with the reflow device for repeated infinite cycles. [Prior Art] Φ According to 'the precision machine often needs to control the movement of the working platform or the processing component', and in order to control the moving feed amount with precise and small friction coefficient, the movement is precisely driven by the ball screw, and A screw and a nut are arranged on the ball screw. In order to reduce the friction, a plurality of balls are used between the screw and the nut, and the ball must be repeatedly cycled in the nut. The cycle is to use the setting cycle. The system is completed by a circulation system on the nut, as shown in Figs. 8 and 9, which is the patent of Japanese Patent Application No. 2003-49842, which can be seen as the center of the return flow path 61 along the return flow path 61. The top edge of the line is provided with a guiding groove 62 for providing a chain 7 loop, and only one side of the chain 70 is provided with a connecting portion 71 for connecting the spacers 72 in series and driving the rolling elements 80 between the spacers 72 to move. The 71 is moved in the guiding groove 62 to move the 'rolling element 80 away from the screw and the shaft-reflow shape; the above structural design has the following problems, including: the reflow cover 60 is excessively brittle Weak: the return cover 60 is in the form of opening to the screw due to the return passage 61, and the thickness of the bottom portion is very thin. For example, when the chain 70 is to be integrated with the connecting portion 71, the guiding groove 71 is used to drive the rolling element. 8〇, the structural strength is limited, so there is a need for improvement. The return cover 60 guides the chain 70 to have insufficient stability: the return passage 61 is in the form of a screw to expose the wire member 80, so that when the return cover 6 is heated or deformed, the rolling element 80 is τ Insufficient degree of orientation, it is easy to produce a collision with the tooth peaks of the screw, which causes improper friction and interference, and therefore may cause the noise of the person to make a person's damage even to the damage of the component 8 () and related components. By. The money bar 70 is extremely liable to cause undue damage: when the chain entrains the rolling element 80 into the cover 6Q, 'because the connecting portion 71 is moved at the maximum diameter of the curve of the 匕k path 61, the connection portion η Here, the curved shape is perpendicular to the direction in which the connecting portion 71 can be expected, that is, the connecting portion 71 is the most outwardly and most versatile. That is to bear the power of the financial resources, it is easy to cause private damage due to _, such as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Under the __ under the dual gravity of the gravity force and the lake pen, it is expected that the chain 7G will appear as an "eight" shape, and the deformation of 201018814 will be a big one. The eight-shaped movement is not only easy to cause the connecting portion 71 to be disengaged from the guiding groove 62, but is more likely to be broken due to improper pulling, and thus the frictional resistance a of the chain 70 and the returning cover 60 is removed to make the circulation motion not smooth, and the structure is not smooth. The damage is even more serious, so there is a need for improvement. 4. "The production of the back cover 60 is not easy: because the return cover 6 is a one-piece structure or a two-half type structure is combined with a high frequency to form a scorpion, and so on. The two-half-type structure is fused into an integrated structure or an integrated structure, and the directly integrated structure has its own difficulty in demoulding, and the structure of the two-half type re-integrated into a body is also There is one more procedure in the system, and it must be very accurate when it is integrated. Otherwise, it will easily cause inaccuracies in the return path 61 or other structures, and it must be eliminated as a defective product, which does not meet the principle of economic saving. ❹ 【Contents】 Technical problems to be solved: At present, the conventional ball screw is arranged on the outside of the nut. When the chain is entrained and rolled into the return cover, it will be due to the weak structure. Producing a difference in twist, and causing the chain and the weak structure of the fit to exhibit an "eight" shape movement, which is very easy to cause damage to the related structure and the movement of the joint from the guide groove causes the movement to not turn greener The knot __ is based on how to avoid the break of the key 201018814 and increase the movement smoothness of the chain in the return passage and the guide groove.

It is located in the guiding space a, and when entering the returning channel D, the connecting portion 42 is slid in the guiding arch groove 33. With the above structure, the rotation of the shaft 10 causes the nut 2 to be linearly moved by the rolling group F on the shaft 10, and when the rolling group F rolls on the load path B, The connecting portion 42 moves along the guiding space A. When the rolling and F = moving close to the reflow device C, the rolling group F enters the interface D1 of the crucible return path D that is connected to the load path B. The inlet and outlet portion D2 of the reflow device C, the clock; the crucible 42 is connected to the guiding space 33 along the guiding space A to continue to receive the guiding, and passes through at least one of the tooth peaks 12, 23' and returns to the cycle. The start end @ 俾 of the load path b of the path E performs a repeated cyclic action to cause the nut 20 to move smoothly. Wherein, the connecting portion D2 and the guiding space A have a beveled opening edge 320 matching the guiding edge 340 of the protrusion 34, so that the connecting portion of the rolling group F can smoothly enter the guiding slot. 33β' and the rolling element 5 of the rolling group f can also be surely entered into the return channel D without causing unnecessary jumping, and the guiding portion 42 can be smoothly guided without interference in the guiding groove 33. Reducing the (four) sound generated by the interference and breaking the leading edge of the rolling path 该 when the rolling group _ enters the recirculating device C, and is added to the leading edge of the bump % in the load path , The returning device c is obliquely diverted by the guiding edge 34G to enter the return channel D with the more limbs. 201018814 By the above specific structure, the following benefits can be achieved: () The opening edge 32 of the slave/❹Π2 is designed to improve the smoothness of the rolling group F into the return channel D: the present invention is utilized for a nut 2 Between the 〇 and the shaft 1 设有, the opposite rolling groove η and the rolling groove 22 become a load path b, and the tooth peaks 12, 23 between the rolling grooves 4 sing the guiding space A, and the reflow device is connected The corresponding return channel D and the two grooves 33 are also provided, so that the guiding space A and the two guiding grooves 33 can be disposed on both sides of the moving path of the rolling group F, and cooperate with the opening edge The beveled design 'so that when the connecting portion 42 of the rolling group F is guided to move, the #ring is smoother and the rolling is smoother and the F is not easily opened, and the breaking is minimized. . (1) The reflow device C is quick and convenient to make the combination: the reflow device has two reflowing half-type elements 30 which are directly assembled in the opposite fitting structure, that is, placed in the receiving groove 24 of the nut 20 It is fast and convenient. This pre-combined structure is also very convenient for the post-production process. It is also very convenient to integrate the processing. ® (3) The structural strength of the overall reflow device c is large: by the arrangement of the bump 34 and the support portion 35 and the intermediate groove of the guide groove 33 at the intermediate return portion 32, the guide groove 33 is The thickness of the outer edge surface of the shaft 10 is increased to effectively increase the overall strength 'to increase the service life of the entire reflow device C. (4) The rolling guide F of the rolling group F in the reflow device C is more stable: the guiding groove 33 is extended in the middle of the returning path D, and the bending direction is the rolling group. The direction in which the connecting portion 42 of F can be deformed, so that the 12 201018814 rolling group F can be maintained in an optimal state, and the guiding groove 33 and the position of the guiding block 33 and the supporting portion 35 are matched by the leading edge 34 〇 'Rolling the rolling group ρ into the return channel D in the reflow device C, more reliably, the support of the rolling element 50 of the rolling group F is more effective, and the connecting portion 42 is required The reduction of the support force can reduce the interference caused by insufficient support, and effectively improve the stability of the overall rolling. (5) reducing the damage that may be caused by the rolling group F: the two mutually opposing turbulent half-shaped pieces 30 are located in the convex block % disposed in the load path B, and the convex piece 34 is on the rolling element The end of the 50 in and out is provided with a leading edge 34〇, and the leading edge _俾 guides the recirculating device c to enter the reducing channel D more uniformly, so that the wire element 5 〇 circulates more smoothly. The strength of the supporting member 5Q is more sufficient to reduce the mutual support of the connecting portion 42 and the guiding groove 33@, thereby effectively reducing the improper force of the connecting portion 42, so that the connecting portion is to be The possibility of tooth damage is minimized.
