In order to understand the technical features and practical effects of the present invention in detail and to implement it according to the content of the invention, a preferred embodiment as shown in the figure is further described in detail as follows:

As shown in Figures 1 to 3, the preferred embodiment of the present invention is a horizontal lathe suitable for large-diameter workpieces, which includes a main bed 10, a sub-bed 20, a processing device 30 and a plurality of assembly components 40. The main bed 10 and the sub-bed 20 are independent structures and are arranged at intervals. As shown in Figure 2, the plurality of assembly components 40 are arranged at intervals between the main bed 10 and the sub-bed 20 to assemble and combine the main bed 10 and the sub-bed 20.

As shown in Figures 1 and 2, the main bed 10 is long and can be used to mount a workpiece, and the workpiece has an extension direction. Specifically, the main bed 10 has two ends that are located opposite to each other, and a main rail extending toward the two ends of the main bed 10. A clamping assembly 11 (or headstock) is provided at one end of the main rail. A tailstock (not shown) is usually provided on the main rail. The tailstock can move along the main rail to move away from or close to the clamping assembly 11, so that workpieces of different lengths can be fixedly mounted between the clamping assembly 11 and the tailstock. In other words, the extension direction of the workpiece is the extension direction of the main rail. In addition, other mechanisms that assist in supporting the workpiece can be installed on the main rail.

As shown in Figures 1 and 2, the auxiliary bed 20 is long and has a linear guide rail 21 extending toward the opposite ends of the auxiliary bed 20. The processing device 30 is disposed on the auxiliary bed 20 and can move linearly along the linear guide rail 21 to process different positions of the workpiece. The detailed structure of the processing device 30 will be described later. As shown in Figures 2 and 3, as mentioned above, the main bed 10 and the auxiliary bed 20 are independent structures, which are manufactured and formed separately and then assembled and combined through the plurality of assembly components 40.

As shown in FIGS. 3 to 5 , each of the assembly components 40 includes a first assembly component 41, a second assembly component 42, a spacing compensation plate 43, and a coupling component 44. The first assembly component 41 can be fixed to the main bed platform 10, and the second assembly component 42 can be fixed to the auxiliary bed platform 20. The first assembly component 41 and the second assembly component 42 can be fixed by screw thread locking, but are not limited thereto. The coupling component 44 can be coupled to the first assembly component 41. 1. The spacing compensation plate 43 and the second assembly 42 are so that the spacing compensation plate 43 is clamped between the first assembly 41 and the second assembly 42. In the preferred embodiment of the present invention, the coupling member 44 is a combination of a screw and a nut. As shown in FIG6 , the screw of the coupling member 44 sequentially penetrates the second assembly 42, the spacing compensation plate 43 and the first assembly 41 and is screwed with the nut, thereby fixing the above three relatively.

In other embodiments, the screw of the coupling member 44 may be reversely arranged so that it sequentially passes through the first assembly member 41, the spacing compensation plate 43 and the second assembly member 42 and then is screwed with the nut. Alternatively, the coupling member 44 may only include the screw, which passes through the second assembly member 42 and the spacing compensation plate 43 and then is screwed into the screw hole on the first assembly member 41. As long as the first assembly member 41, the spacing compensation plate 43 and the second assembly member 42 can be coupled, the form of the coupling member 44 is not limited by the preferred embodiment of the present invention. In addition, in the preferred embodiment of the present invention, gaskets are provided between the screw of the coupling member 44 and the second assembly member 42, and between the nut of the coupling member 44 and the first assembly member 41 to reduce wear.

By clamping the distance compensation plate 43 between the first assembly part 41 and the second assembly part 42, the assembly tolerance of the main bed 10 and the auxiliary bed 20 can be corrected, so that the linear guide rail 21 is parallel to the extension direction of the workpiece, that is, the main guide rail of the main bed 10, so as to achieve better assembly accuracy and improve the processing accuracy of the horizontal lathe. The specific method is as follows.

The present invention uses the spacing compensation plate 43 of the plurality of assembly components 40. Before the horizontal lathe of the present invention is shipped, the main bed 10 and the auxiliary bed 20 are pre-assembled, and each segment of the main bed 10 between the two ends is combined with the auxiliary bed 20 by the first assembly component 41 and the second assembly component 42 of the plurality of assembly components 40 arranged at intervals, and the parallelism between the main guide rail of the main bed 10 and the linear guide rail 21 of the auxiliary bed 20 is measured. ; Then, according to the measurement results, the distance between the first assembly 41 and the second assembly 42 of each assembly 40 is adjusted, that is, the distance between each segment of the main bed 10 and the auxiliary bed 20 is adjusted, so that the main guide rail and the linear guide rail 21 are corrected to be parallel. After the correction is completed, the thickness of the corresponding distance compensation plate 43 is designed or processed according to the size of the distance between the first assembly 41 and the second assembly 42 of each assembly 40.

By the above method, during assembly and fixing, the distance compensation plate 43 is clamped between the corresponding first assembly part 41 and the second assembly part 42 to fill the distance required for correction to parallelism between the first assembly part 41 and the second assembly part 42 of each assembly part 40. Thus, after the plurality of assembly parts 40 assemble the main bed 10 and the auxiliary bed 20, the main guide rail of the main bed 10 and the linear guide rail 21 of the auxiliary bed 20 can be directly parallel, so that the main bed 10 and the auxiliary bed 20 have good assembly accuracy, and the horizontal lathe of the present invention has good processing accuracy after assembly.

Compared with the existing lathes, the main rail and the auxiliary rail included in the bed are integrally formed, and interference is easy to occur when processing workpieces with larger diameters. The present invention sets the main bed 10 for fixing the workpiece and the auxiliary bed 20 for setting the processing device 30 independently, and during assembly, the spacing compensation plates 43 of the plurality of assembly components 40 are used to calibrate the extension direction of the workpiece, that is, the main guide rail of the main bed 10 and the linear guide rail 21 of the auxiliary bed 20 are directly parallel after assembly, so as to provide a horizontal lathe suitable for processing workpieces with larger diameters and having good assembly and processing accuracy.

In addition, the present invention is applicable to horizontal lathes for large-diameter workpieces. Since the multiple assembly components 40 are used to assemble and combine the separate main bed 10 and the auxiliary bed 20, when they are ready to leave the factory, the main bed 10 and the auxiliary bed 20 can be disassembled for transportation, which takes up less space and improves the convenience of transportation. Since the multiple assembly components 40 contain the spacing compensation plate 43 for calibration, the assembly and combination can still maintain good assembly accuracy after being transported to the customer end. The horizontal lathe of the present invention has good processing accuracy after assembly.

The horizontal lathe of the present invention adopts the spacing compensation plate 43 of the plurality of assembly components 40. When filling the corresponding correction adjusted spacing between the first assembly component 41 and the second assembly component 42, the manufacturing tolerance of the first assembly component 41 and the second assembly component 42 is actually corrected. Specifically, since the spacing compensation plate 43 is a plate body, it is relatively easy to design, manufacture and process. The spacing compensation plate 43 can even be a plate body of unequal thickness. With the pre-assembly and measurement and continuous correction, the manufacturing tolerance and assembly tolerance of the main bed 10 and the auxiliary bed 20 and the manufacturing tolerance of the first assembly component 41 and the second assembly component 42 can be corrected at the same time, so that the horizontal lathe of the present invention has excellent processing accuracy.

As shown in FIG. 5 and FIG. 7, in a preferred embodiment of the present invention, the spacing compensation plate 43 further includes a notch 431, and the notch 431 is recessed from the bottom end of the spacing compensation plate 43 toward the top end of the spacing compensation plate 43. The spacing compensation plate 43 can move relative to the coupling member 44, so that the coupling member 44 enters the notch 431 from the notch of the notch 431 and abuts against the bottom of the notch 431. Through the notch 431, the spacing compensation plate 43 can be conveniently Specifically, when the spacing compensation plate 43 is inserted and measured again, if calibration is still required, the spacing compensation plate 43 can be pulled out by slightly loosening the coupling member 44. After redesign or reprocessing, the new spacing compensation plate 43 can be quickly inserted between the first assembly 41 and the second assembly 42, thereby increasing the convenience and efficiency of the calibration test process.

As shown in FIG. 5 and FIG. 7, in the preferred embodiment of the present invention, the second assembly part 42 includes a notch 421, and the notch 421 is recessed from the top of the second assembly part 42 toward the bottom of the second assembly part 42. During assembly, the coupling part 44 can be inserted into the notch 421 from the top of the second assembly part 42 and arranged at the bottom of the notch 421. The screw of the coupling part 44 can be directly inserted through the notch 421, which is more convenient in operation.

In addition, the preferred embodiment of the present invention uses the notch 421 of the second assembly 42 and the notch 431 of the spacing compensation plate 43. After the coupling member 44 couples the first assembly 41, the spacing compensation plate 43 and the second assembly 42, the screw of the coupling member 44 is set at the bottom of the notch 421 and presses upward against the bottom of the notch 431, which can fix the height position of the spacing compensation plate 43 relative to the first assembly 41 and the second assembly 42, providing a positioning effect, so that the calibration of the spacing compensation plate 43 for compensation spacing is more accurate.

As shown in FIG. 5 and FIG. 7, in the preferred embodiment of the present invention, each assembly component 40 further includes a positioning member 45, which is a screw rod, which passes through a screw hole provided in the first assembly component 41 and abuts against the second assembly component 42. The positioning member 45 and the coupling member 44 are spaced apart. In the pre-assembly process, the adjustment personnel adjust the distance between the first assembly component 41 and the second assembly component 42 of each assembly component 40 by twisting the screw rod and the nut of the coupling member 44. At this time, by twisting the positioning member 45, the positioning member 45 is inserted into the second assembly component 42. The positioning member 45 of the first assembly 41 is placed against the second assembly 42 for positioning, so as to prevent the first assembly 41 and the second assembly 42 from being offset, and the adjuster can also obtain the size of the distance between the first assembly 41 and the second assembly 42 based on the distance of twisting the positioning member 45. For example, the size of the positioning member 45 can be calculated by the number of turns of twisting the positioning member 45 or by marking the positioning member 45 for measurement, and the size of the distance compensation plate 43 can be designed and processed accordingly.

In the preferred embodiment of the present invention, the positioning member 45 passes through the first assembly member 41 and abuts against the second assembly member 42. In other embodiments, the positioning member 45 can also pass through the second assembly member 42 and abut against the first assembly member 41. It can also play a role in positioning and assisting in designing the size of the spacing compensation plate 43 when adjusting the distance between the first assembly member 41 and the second assembly member 42 during the pre-assembly process. The arrangement form of the positioning member 45 is not limited to the preferred embodiment of the present invention.

As shown in FIG. 3, FIG. 8 and FIG. 9, in a preferred embodiment of the present invention, the horizontal lathe further comprises an end assembly component 40A, which is substantially the same as the assembly component 40, and comprises the first assembly component 41A, the second assembly component 42A, the spacing compensation plate 43A, the coupling component 44A and the positioning component 45A, wherein the coupling component 44A is only a screw, which sequentially penetrates the coupling hole 411 of the first assembly component 41A, the notch 431 of the spacing compensation plate 43A and is screwed into a coupling screw provided in the second assembly component 42A. Hole 423; The main difference between the end assembly component 40A and the assembly component 40 is that the second assembly component 42A is further formed with a positioning recess 422, which is L-shaped. After the second assembly component 42A is fixed to the auxiliary bed 20, as shown in Figures 3 and 6, a corner of one end of the auxiliary bed 20 that is relatively close to the main bed 10 will be attached to the L-shaped positioning recess 422, so as to locate the position of the auxiliary bed 20 and its linear guide rail 21 relative to the main bed 10, so as to determine the end point of the processing stroke of the horizontal lathe.

As shown in Figures 10 to 13, in the preferred embodiment of the present invention, the movement of the three linear coordinate axes of the horizontal lathe is completed by the processing device 30. Specifically, the processing device 30 includes a saddle 31, a column 32, a ram support 33 and a ram assembly 34. As shown in Figure 10, the saddle 31 is installed on the linear guide rail 21 of the auxiliary bed 20, so that the processing device 30 can move along the linear guide rail 21 in the length direction of the workpiece (as shown by the arrow in Figure 10). This is the movement on one of the linear coordinate axes (defined as the X axis).

As shown in Figures 10 and 11, the column 32 extends upright from the saddle 31 and is hollow. As the main structure of the processing device 30, the column 32 is provided with two parallel slide rails 321 on opposite sides close to and far from the main bed 10, respectively. The slide rails 321 extend toward the top and bottom of the column 32. The ram support 33 penetrates the hollow part of the column 32 and protrudes from the opposite sides of the column 32. Each of the slide rails The bar 321 has a corresponding slider group, each slider group includes a plurality of slide rail sliders 331, the slide rail sliders 331 are fixed to the ram support 33, and are arranged on the corresponding slide rail bar 321, whereby the ram support 33 can move along the slide rail bar 321 in the extension direction of the column 32 with the slide rail sliders 331 (as shown by the arrow in Figure 11), which is the movement on another linear coordinate axis (defined as the Y axis).

As shown in FIG. 12 and FIG. 13 , the ram assembly 34 is surrounded by the ram support 33, and a plurality of planar bearings 35 and two guide rails 36 are disposed between the two. Each of the planar bearings 35 is in the shape of a long strip, and each of the guide rails 36 includes a track strip 37 and at least one slider 38. The ram assembly 34 includes two opposite sides. The plurality of planar bearings 35 and the two guide rails 36 are disposed on both sides of the ram assembly 34. , wherein the plurality of plane bearings 35 are fixed on the ram support 33, the rail 37 and the slider 38 are arranged horizontally, the rail 37 is fixed to one side of the ram assembly 34, and the slider 38 is fixed to an inner vertical surface of the ram support 33; in other embodiments, the slider 38 may be fixed to the ram assembly 34, and the rail 37 may be fixed to the ram support 33.

The slider 38 is concave-convexly matched with the rail 37. Specifically, the slider 38 has a setting groove. The cross section of the space in the setting groove is the same as the cross section of the rail 37. Thus, the slider 38 can be engaged with the rail 37 and can move relatively along the rail 37. When the ram assembly 34 moves linearly relative to the ram bearing 33 through the guide rail 36, it will also stick to the planar bearing 35. The tool 341 at one end of the ram assembly 34 moves closer to or farther from the workpiece on the main bed 10, which is the movement on the last linear coordinate axis (defined as the Z axis). The strip-shaped plane bearing 35 is specifically a plane roller bearing (shown as a long block in Figures 12 and 13), which is used to provide the ram assembly 34 with smooth, low-friction linear movement.

Compared with the method of using the planar bearing 35 on both sides of the ram assembly 34 to cooperate with the ram support seat 33, the preferred embodiment of the present invention uses the planar bearing 35 only on one side of the ram assembly 34, and uses the guide rail 36 with matching shape and rigidity on the other side of the ram assembly 34, thereby, the linear movement of the ram assembly 34 relative to the ram support seat 33 is less likely to produce offsets on other linear coordinate axes, which can provide better processing accuracy.

The above is only the preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person with ordinary knowledge in the relevant technical field, within the scope of the technical solution proposed by the present invention, can make partial changes or modifications to the technical content disclosed by the present invention, and within the scope of the technical solution of the present invention, and all of them are still within the scope of the technical solution of the present invention.
