[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein.

The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.
[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0026] Please see the appendix Figure 1 and Figure 3 As shown, this utility model provides a lathe tooling fixture, including a base 10, a support frame 11 fixed to the upper end of the base 10, a lifting mechanism 12 assembled inside the support frame 11, a rotating mechanism 20 assembled at one end of the lifting mechanism 12, a housing 30 fixed to the end of the lifting mechanism 12 away from the rotating mechanism 20, a second motor 31 fixed to one side of the housing 30, the output end of the second motor 31 extending into the interior of the housing 30, a third gear 32 fixed to the output end of the second motor 31 and located inside the housing 30, and a threaded rod 33 rotatably connected inside the housing 30, with both sides of the threaded rod 33 penetrating the housing. The sidewall of the housing 30 extends to the outside of the housing 30. A fourth gear 34 is fixed on the outside of the threaded rod 33 and inside the housing 30. The third gear 32 and the fourth gear 34 are meshed together. Moving plates 35 are threadedly connected to the outside of the threaded rod 33 and on both sides of the housing 30. A connecting block 36 is provided at the end of each moving plate 35 away from the threaded rod 33. A clamping plate 37 is fixed on the side of each connecting block 36 that is close to each other. A limiting rod 38 is fixed inside the housing 30. The two sides of the limiting rod 38 penetrate the sidewall of the housing 30 and extend to the outside. The limiting rod 38 and the two moving plates 35 are slidably connected.
[0027] In this embodiment, during operation, the base 10 is securely installed at the designated position on the lathe to ensure that the fixture will not shift during subsequent operations. The workpiece to be processed is placed between the two clamping plates 37, and the second motor 31 is started. Since the output end of the second motor 31 extends into the interior of the housing 30 and is rotatably connected to the housing 30, and a third gear 32 is fixed inside the housing 30 at the output end of the second motor 31, the third gear 32 rotates. Because the third gear 32 and the fourth gear 34 are meshed, the third gear 32 drives the fourth gear 34. The fourth gear 34 has a threaded rod 33 fixed inside, so the fourth gear 34 drives... When the threaded rod 33 rotates, the moving plate 35 and the limiting rod 38 slide together. Because the moving plate 35 is threadedly connected to the threaded rod 33 and is restricted from rotating by the limiting rod 38, the moving plate 35 slides along the limiting rod 38 towards each other, pushing the connecting block 36 and the clamping plate 37 to clamp the part. The anti-slip surface on the clamping plate 37 prevents the part from sliding. The rotating mechanism 20 can make the outer shell 30 and the clamping plate 37 drive the workpiece to rotate to different angles, meeting the needs of processing complex parts on multiple surfaces or angles. The overall height of the clamping plate 37 can be flexibly adjusted by the lifting mechanism 12 to adapt to parts of various heights to be processed, reducing the trouble of changing different tooling due to differences in workpiece height and reducing production costs.
[0028] It should be noted that the threaded rod 33 has two external threads on its outer side, and the two external threads rotate in different directions. The two movable plates 35 are threaded to both sides of the outer side of the threaded rod 33. When the threaded rod 33 rotates, the two movable plates 35 can move closer to each other or further away from each other.
[0029] In a preferred embodiment, please refer to Figure 3 Both sides of the outer casing 30 are fixed with protective plates 39, and the movable plate 35 is located inside the protective plate 39. The two sides of the threaded rod 33 extend into the interior of the protective plate 39, and the threaded rod 33 and the protective plate 39 are rotatably connected.
[0030] In this embodiment, the guard plate 39 can effectively block the splashes of chips, coolant and other materials generated during the processing, preventing them from entering the mating gap between the moving plate 35 and the threaded rod 33, preventing chips from jamming the moving plate 35, extending the service life of the components, and ensuring the stable operation of the fixture.
[0031] Secondly, please refer to again Figure 3 Both of the two clamping plates 37 have anti-slip surfaces on their sides that are close to each other.
[0032] In this embodiment, the anti-slip surface significantly increases the friction between the clamping plate 37 and the workpiece. During lathe machining, the workpiece is subjected to external forces such as cutting forces. The anti-slip surface can effectively prevent the workpiece from shifting or sliding between the clamping plates 37, ensuring that the workpiece remains in a fixed position throughout the machining process and improving clamping stability.
[0033] Secondly, please refer to the following as well. Figure 1 and Figure 3 A square groove 40 is provided at one end of the movable plate 35 near the connecting block 36. A square plate 41 is fixed at one end of the connecting block 36 near the movable plate 35. The square groove 40 and the square plate 41 are compatible and are fixedly connected by bolts.
[0034] In this embodiment, a square plate 41 is fixed to one end of the connecting block 36 near the moving plate 35, and a square groove 40 is provided on one end of the moving plate 35 near the connecting block 36. When it is necessary to replace the clamping plate 37 of different specifications, the old connecting block 36 can be removed by loosening the bolts, and the new connecting block 36 and clamping plate 37 can be replaced and then reinstalled and fixed. The square plate 41 can be quickly aligned and embedded into the square groove 40, and then tightened with bolts. The operation is simple. When maintaining the fixture, replacing worn parts or adjusting the structure, the separation and installation of the connecting block 36 and the moving plate 35 can be completed quickly, which greatly saves time and labor costs and improves the efficiency of equipment operation and maintenance.
[0035] To further understand and explain, Figure 2 For example, the lifting mechanism 12 includes a lifting plate 13, a support plate 14, and an electric push rod 15. The lifting plate 13 is slidably connected to the inside of the support frame 11. The support plate 14 is fixed to the end of the lifting plate 13 away from the base 10. The electric push rod 15 is fixed to the upper end of the support frame 11, and the output end of the electric push rod 15 passes through the support frame 11 and extends to the upper end of the lifting plate 13. The output end of the electric push rod 15 is fixedly connected to the lifting plate 13.
[0036] In this embodiment, when the lifting mechanism 12 is working, the electric push rod 15 is activated, and its output end can extend or shorten. Since the output end of the electric push rod 15 is fixed to the lifting plate 13, and the lifting plate 13 is slidably connected inside the support frame 11, the output end of the electric push rod 15 can drive the lifting plate 13 to rise or fall smoothly along the support frame 11, thereby driving the support plate 14, which is fixed at the end away from the base 10, to rise synchronously. This allows for quick and precise adjustment of the fixture height, easily adapting to parts of different heights, without the need for cumbersome tooling changes or adjustments to other lathe components, greatly improving processing efficiency and ensuring the stability and accuracy of height adjustment.
[0037] In a preferred embodiment, please refer to Figure 4 The support frame 11 has sliding grooves 16 on both sides inside, and the lifting plate 13 has sliding plates 17 fixed on both sides. The sliding grooves 16 and sliding plates 17 are compatible and slidably connected.
[0038] In this embodiment, the slide 16 is adapted to the slide plate 17, and the slide 16 and the slide plate 17 are slidably connected, providing precise guidance for the lifting movement of the lifting plate 13 and preventing the lifting plate 13 from shaking or deviating during its ascent or descent.
[0039] Secondly, please refer to again Figure 2 and Figure 3 The rotating mechanism 20 includes a first motor 21, a first rotating rod 22, a load-bearing plate 23, a support block 24, a first gear 25, a second rotating rod 26, a second gear 27, and a rotating plate 28. The first motor 21 is fixed to the upper end of the support plate 14, the first rotating rod 22 is fixed to the output end of the first motor 21, the load-bearing plate 23 is fixed to one end of the lifting plate 13, the support block 24 is fixed to one side of the load-bearing plate 23, the first gear 25 is fixed to the outside of the first rotating rod 22, the second rotating rod 26 is rotatably connected to the inside of the lifting plate 13, and both ends of the second rotating rod 26 penetrate the side wall of the lifting plate 13 and extend to the outside of the lifting plate 13, the second gear 27 is fixed to the end of the second rotating rod 26 near the first gear 25, and the first gear 25 and the second gear 27 are meshed together, and the rotating plate 28 is fixed to the end of the second rotating rod 26 away from the second gear 27, and the rotating plate 28 is fixedly connected to the outer shell 30.
[0040] In this embodiment, when the machining angle of the workpiece needs to be adjusted, the machining range of the lathe is expanded by the rotating mechanism 20. During operation, the first motor 21 is started, which drives the first rotating rod 22 fixed at its output end to rotate. The first gear 25 on the outside of the first rotating rod 22 rotates accordingly. Since the first gear 25 meshes with the second gear 27, the second gear 27 rotates. Since the second gear 27 is fixedly connected to the second rotating rod 26, the rotation of the second gear 27 drives the second rotating rod 26 to rotate within the lifting plate 13. Since the rotating plate 28 is fixed to the end of the second rotating rod 26 away from the second gear 27, and the rotating plate 28 is fixedly connected to the outer shell 30, the rotation of the second rotating rod 26 drives the rotating plate 28 to rotate. Since the rotating plate 28 is fixedly connected to the outer shell 30, the outer shell 30 and the clamping plate 37 and other components connected to it rotate accordingly, meeting the needs of machining complex parts on multiple surfaces or at multiple angles, avoiding multiple clamping of workpieces, reducing positioning errors, and improving machining accuracy.
[0041] The working principle of this utility is as follows:
[0042] During operation, the base 10 is first installed in the designated position on the lathe, and the workpiece to be processed is placed between the two clamping plates 37. The second motor 31 is started, and its output end drives the third gear 32 to rotate. Through meshing with the fourth gear 34, the threaded rod 33 is driven. Because the moving plate 35 is threadedly connected to the threaded rod 33 and is restricted by the limiting rod 38, the moving plate 35 drives the clamping plate 37 to clamp the workpiece. When it is necessary to adjust the height of the fixture, the lifting plate 13 is driven to rise and fall along the support frame 11 by adjusting the electric push rod 15 of the lifting mechanism 12, thereby adjusting the height of the fixture. The first motor 21 drives the first rotating rod 22 and the first gear 25 to rotate. The first gear 25 is meshed with the second gear 27, so the rotation of the second gear 27 drives the second rotating rod 26 to rotate. The rotation of the second rotating rod 26 drives the rotating plate 28, the outer shell 30, and the clamping plate 37 to rotate, thereby realizing the adjustment of the workpiece angle and meeting different processing requirements.
[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
