Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathe equipment, and specifically to a machining device for a numerically controlled double-head lathe. Background Technique

[0002] A numerically controlled double-head lathe is a high-precision and high-efficiency automated machining equipment, which is widely used in the field of mechanical manufacturing. Its main feature is to achieve precise machining of workpieces through a digital control system, and it can simultaneously use the machining heads on both sides to perform two-way operations on the workpieces, thereby significantly improving the machining efficiency and consistency. Compared with traditional lathes, numerically controlled double-head lathes can not only complete the machining of parts with complex shapes, but also have higher stability and repeatability, so they occupy an important position in modern industrial production.

[0003] In the prior art, the existing numerically controlled double-head lathe is usually equipped with a workpiece fixture inside to fix the workpiece in the machining area. During the machining process, after the workpiece is clamped and fixed by the fixture, the machining heads on both sides are controlled to perform synchronous or step-by-step machining on the workpiece. This design can meet most conventional machining requirements, especially showing high reliability and efficiency in mass production.

[0004] However, after the fixture in the existing machining device of the numerically controlled double-head lathe clamps the workpiece, its position is relatively fixed and difficult to adjust flexibly. When it is necessary to machine different positions or different angles of the workpiece, it is often necessary to perform multiple clamping operations to adapt to the new machining requirements. This not only increases the adjustment time and reduces the overall machining efficiency, but also introduces additional operation steps and error risks due to multiple clamping operations, thereby having an adverse impact on the machining accuracy. For this reason, the present invention proposes a machining device for a numerically controlled double-head lathe to solve the above problems. Summary of the Invention

Detailed implementation manners

[0029] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 to 6 , the present invention provides a technical solution: a numerical control double-head lathe processing device, including: a processing table 1, which serves as the main body of the entire device to support the entire device. A regulating component is arranged in the middle of the upper surface of the processing table 1. Through the arrangement of the regulating component, it is convenient to adjust the position and angle of the workpiece. A clamping component is arranged above the regulating component, and the arrangement of the clamping component facilitates the quick disassembly or clamping of the workpiece.

[0031] The adjusting component includes a support disk 2 which supports the whole adjusting component. A rotating plate 3 is rotatably installed on the upper side of the support disk 2. By rotating the rotating plate 3, the workpiece can be indirectly driven to rotate, so as to adjust the placing angle of the workpiece. A driving disk 4 is rotatably installed inside the rotating plate 3. A moving block 5 is slidably connected to the upper side of the driving disk 4. By rotating the driving disk 4, the moving block 5 is indirectly driven to move. The moving block 5 is slidably sleeved on a limiting rod 6. The limiting rod 6 limits the moving block 5, so that it can move along the axis direction of the limiting rod 6. Both ends of the limiting rod 6 are fixedly connected to both sides of the rotating plate 3. The clamping component includes a support block 7 which facilitates the indirect support of the workpiece. The lower surface of the support block 7 is fixedly connected to the moving block 5. A placing disk 8 is fixedly installed on the upper side of the support block 7. The placing disk 8 is used to place the workpiece. Slide holes 9 are symmetrically formed on both sides of the surface of the placing disk 8. A slider 10 is slidably connected inside the slide hole 9. The slide hole 9 limits the slider 10. The bottom end of the slider 10 is rotatably connected to one end of a connecting plate 11. The other end of the connecting plate 11 is rotatably connected to a rotating frame 12. The top end of the slider 10 is fixedly connected to a clamping plate 34 which clamps and fixes the workpiece.

[0032] Place the workpiece on the upper surface of the placing disk 8. By rotating the rotating frame 12, one end of the connecting plate 11 is driven to move. The other end of the connecting plate 11 is rotatably connected to the bottom of the slider 10, so as to pull the slider 10 to slide inside the slide hole 9, and then make the two sliders 10 move towards each other until the clamping plate 34 clamps the workpiece. When it is necessary to adjust the processing angle of the workpiece, just control the rotation of the rotating plate 3. When it is necessary to adjust the position of the workpiece, control the rotation of the driving disk 4, so that the driving disk 4 indirectly drives the moving block 5 to move. The moving block 5 moves along the axis direction of the limiting rod 6 under the limitation of the limiting rod 6, and then the position of the workpiece is adjusted, thus avoiding the trouble of clamping the workpiece multiple times, improving the processing efficiency and enhancing the processing accuracy.

[0033] Embodiment 2: On the basis of Embodiment 1, the lower surface of the support disk 2 is fixedly connected to the upper surface of the processing table 1. The center of the upper surface of the support disk 2 is fixedly connected with a support cylinder 13. At the edge of the upper surface of the support disk 2, a lower motor 14 is fixedly installed. The output end of the lower motor 14 is fixedly connected with a small gear 15. Thus, the small gear 15 can be driven to rotate by the lower motor 14. One side of the small gear 15 is in meshing transmission with a toothed ring 16. The toothed ring 16 is fixedly connected to both sides of the lower surface of the rotating plate 3 through the cooperation of a connecting block 17 and a bolt. In the middle of the lower surface of the rotating plate 3, a limiting sleeve 18 is fixedly connected. The outer circumferential surface of the limiting sleeve 18 is rotatably sleeved in the support cylinder 13. The support cylinder 13 limits the limiting sleeve 18, thereby improving its stability during rotation. The inner circumferential surface of the limiting sleeve 18 is sleeved with a connecting shaft 19 and is rotatably connected to the connecting shaft 19. The limiting sleeve 18 limits the connecting shaft 19. The top end of the connecting shaft 19 is fixedly connected to the lower surface of the driving disk 4. On one side of the support cylinder 13, an upper motor 20 is provided. The upper motor 20 is fixedly installed on the lower surface of the rotating plate 3. The rotating plate 3 stably supports the upper motor 20. The output end of the upper motor 20 is fixedly installed with a driving gear 21. One side of the driving gear 21 is meshed with a driven gear 22. The driving gear 21 and the driven gear 22 are in meshing transmission. The driven gear 22 is fixedly sleeved on the connecting shaft 19. On the upper surface of the driving disk 4, a spiral groove 23 is opened. A slide bar 24 is slidably connected in the spiral groove 23. The slide bar 24 is fixedly connected to the moving block 5.

[0034] After the workpiece is clamped and fixed, during the workpiece processing, when it is necessary to adjust the placement angle of the workpiece, by controlling the lower motor 14 to start, the lower motor 14 drives the small gear 15 fixedly installed at its output end to rotate. Under the rotation of the small gear 15, it is in meshing transmission with the toothed ring 16. The toothed ring 16 thus drives the rotating plate 3 to move. The rotating plate 3 rotates through the rotational connection between the limiting sleeve 18 and the support cylinder 13, and then the self-rotation of the rotating plate 3 is realized, and then the placement angle of the workpiece is indirectly adjusted, which is convenient for subsequent processing. When it is necessary to adjust the position of the workpiece, by controlling the upper motor 20 to start, the upper motor 20 thus drives the driving gear 21 to rotate. The driving gear 21 drives the driven gear 22 through meshing transmission, so that the driven gear 22 drives the driving disk 4 to rotate under the connection of the connecting shaft 19. A spiral groove 23 is opened on the surface of the driving disk 4. Through the constraint of the spiral groove 23 on the slide bar 24, the slide bar 24 moves in the spiral groove 23, and then drives the moving block 5 to move. At the same time, the moving block 5 is slidably sleeved on the limiting rod 6. Finally, the moving block 5 can be driven to move along the axis direction of the limiting rod 6, so as to adjust the position of the workpiece, thereby improving the processing efficiency and avoiding the introduction of additional operation steps and error risks due to multiple clamping.

[0035] Embodiment 3: On the basis of Embodiment 2, the upper surface of the support block 7 is fixedly connected to one end of the limit shaft 25, the other end of the limit shaft 25 is fixedly connected to one end of the support column 26, the other end of the support column 26 is fixedly connected to the bottom of the connecting frame 27, and the top of the connecting frame 27 is fixedly connected to the cushion block 28 by bolts. Through the fixed connection between the limit shaft 25, the support column 26, the connecting frame 27, and the cushion block 28, the placement plate 8 is supported. A worm gear 29 is sleeved on the limit shaft 25 and is rotatably connected. The limit shaft 25 limits the worm gear 29. One side of the worm gear 29 is engaged with a worm 30. Both sides of the worm 30 are rotatably sleeved in the support seat, and the support seat stably supports the worm 30. One end of the worm 30 is fixedly sleeved with a handwheel. The upper surface of the worm gear 29 is fixedly connected to the lower surface of the rotating frame 12 through a connecting column 31, so as to facilitate the rotation of the rotating frame 12 driven by the rotation of the worm gear 29. A limit pin 32 is fixedly sleeved on the outer circumferential surface of the rotating frame 12, and a limit groove 33 is formed on the outer circumferential surface of the connecting frame 27. The rotating frame 12 is rotatably sleeved on the connecting frame 27, and the limit groove 33 is slidably connected with the limit pin 32, thereby improving the rotation stability of the rotating frame 12. Both ends of the rotating frame 12 are rotatably connected to one end of the connecting plate 11 through a pin shaft, and the other end of the connecting plate 11 is rotatably connected to the bottom of the slider 10 through a pin shaft. The sliders 10 are symmetrically arranged with respect to the central plane of the cushion block 28. One side of the clamping plate 34 is fixedly connected with an anti-slip pad 35, and the anti-slip pad 35 improves the friction during the clamping of the workpiece, thereby improving its clamping stability. One side of the upper surface of one of the sliders 10 is fixedly connected with a limit block 36, and a locking rod 37 is sleeved on one side of the limit block 36 and is threadedly connected with the locking rod 37.

[0036] Before processing the workpiece, place the workpiece on the upper surface of the placement plate 8. By rotating the handwheel, the handwheel drives the worm 30 to rotate under the limit of the support seat. The worm 30 is engaged with the worm gear 29 to drive the worm gear 29 to rotate under the limit of the limit shaft 25. While the worm gear 29 rotates, it drives the rotating frame 12 to rotate through the connection of the connecting column 31. The rotating frame 12 rotates on the connecting frame 27 through the sliding fit of the limit pin 32 and the limit groove 33. The rotating frame 12 thus drives the slider 10 to move through the rotational connection of its two ends with the connecting plate 11. The sliders 10 move towards each other under the limit of the sliding holes 9. The sliders 10 then drive the clamping plates 34 to approach the workpiece until the anti-slip pad 35 clamps the workpiece. At the same time, through the threaded connection between the limit block 36 and the locking rod 37, the locking rod 37 is screwed to further lock and limit one of the sliders 10, thereby ensuring the stability during the clamping of the workpiece. In addition, through the cooperation of the worm 30 and the worm gear 29 and its self-locking property, the stability during the clamping process is further improved.

[0037] Embodiment 4: On the basis of Embodiment 3, limiting rails 38 are fixedly installed on both sides of the upper surface of the processing table 1. The limiting rails 38 are slidably connected to the bottom of the shielding cover 39. The shielding cover 39 is symmetrically arranged with respect to the central plane of the processing table 1. One side of the shielding cover 39 is fixedly connected with a transparent plate 40. A central controller 41 is fixedly connected to the surface of one of the shielding covers 39. The central controller 41 is electrically connected to the processing head assembly, and the processing head assembly is arranged on both sides of the support disk 2.

[0038] The limiting rails 38 limit the shielding cover 39, thus facilitating the opening and closing of the shielding cover 39. The arranged shielding cover 39 can prevent the splashing of debris during the processing. The setting of the transparent plate 40 facilitates the viewing during the processing. The central controller 41 is electrically connected to both the upper motor 20 and the lower motor 14, thus facilitating the adjustment of the position and angle of the workpiece.

[0039] During actual use, the processing table 1 serves as the main support structure. Its adjustment assembly consists of a support disk 2, a rotating plate 3, a driving disk 4, a moving block 5, and a limiting rod 6. The clamping assembly includes a support block 7, a placing disk 8, a sliding hole 9, a sliding block 10, a connecting plate 11, a rotating frame 12, and a clamping plate 34. Specifically, during implementation, after the workpiece is placed on the placing disk 8, turning the handwheel drives the worm 30 to mesh with the worm gear 29, driving the rotating frame 12 to stably rotate through the cooperation of the limit pin 32 and the limit groove 33. The connecting plate 11 drives the sliding block 10 to slide towards each other in the sliding hole 9, enabling the clamping plate 34 and the anti-slip pad 35 to clamp the workpiece, and being reinforced by the locking rod 37 and the limit block 36. During angle adjustment, the lower motor 14 drives the small gear 15 to mesh with the gear ring 16, driving the rotating plate 3 to rotate around the support cylinder 13; during position adjustment, the upper motor 20 drives the driving gear 21 to drive the driven gear 22, enabling the spiral groove 23 of the driving disk 4 to push the slide rod 24 and the moving block 5 to translate along the limiting rod 6, realizing the multi-dimensional adjustment of the workpiece, effectively reducing repeated clamping and improving the processing accuracy and efficiency.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
