Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a CNC machining fixture for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, CNC machining technology is widely used for the precision machining of parts. The machining accuracy and consistency of automotive parts are crucial to the performance and safety of the entire vehicle. In order to ensure machining quality, fixtures play a key role in the CNC machining process, used to fix and position the workpiece to prevent it from shifting or vibrating during machining.

[0003] Existing technologies disclose several utility model patents in the field of automotive parts processing technology. Among them, utility model patent with publication number CN216178517U discloses a CNC machining fixture for automotive parts, including a base plate one, a base plate two, and a clamping assembly. The base plate two is symmetrically arranged on one side of the base plate one, and a connecting hinge is installed at the bottom end of the base plate one where it connects to the base plate two. The advantages are: this utility model, through the design of electric push rod one, electric push rod two, clamping plates, pressure plates, and an infrared human body sensor, not only achieves double clamping and fixing of automotive parts, effectively preventing shaking of automotive parts during CNC machining and improving the processing quality of automotive parts, but also effectively prevents accidental activation of the fixture when a human hand is present, improving the safety of fixture use. Through the design of the connecting hinge, lifting handle, support sleeve, and support column, the fixture can be conveniently folded when not in use, effectively reducing the size of the fixture, reducing the space occupied by the fixture, facilitating the storage and maintenance of the fixture, and demonstrating good practicality.

[0004] However, the above methods still have the following drawbacks in actual use: most fixtures limit the two ends of the parts and lack support and fixation for the middle or other key parts of the workpiece. During the processing, the middle of the workpiece is prone to bending or vibration, which affects the processing accuracy and increases the subsequent operation steps. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 andFigure 4 As shown, in this embodiment, a CNC machining fixture for automotive parts includes a support frame 1, a guide shaft 2 rotatably connected inside the support frame 1, a worktable 3 fixedly connected to one end of the guide shaft 2, a third drive motor 8 provided on the side of the support frame 1, a support plate 9 overlapping above the worktable 3, an adjustment structure 5 fixedly connected below the worktable 3, an auxiliary sleeve 7 slidably connected inside the worktable 3, the auxiliary sleeve 7 being connected to the adjustment structure 5, a limit structure 6 slidably connected inside the auxiliary sleeve 7, the limit structure 6 being connected to the support plate 9, the limit structure 6 including an internal gear 601, a second drive motor 603 and a component limit plate 605, a rotating rod 604 fixedly connected inside the component limit plate 605, and a spur gear 602 fixedly connected to the outer surface of the rotating rod 604.

[0023] like Figure 1 and Figure 2 As shown, a component placement slot 4 is provided inside the workbench 3. A fixing collar 10 is fixedly connected to the top of the workbench 3. A support plate 9 is fixedly connected to the top of the fixing collar 10. The output shaft of the third drive motor 8 is connected to one side of the workbench 3. An auxiliary sleeve 7 is connected to the fixing collar 10. The adjustment structure 5 includes a concave plate 501, which is fixedly connected to the bottom of the workbench 3. A first threaded rod 502 is rotatably connected to the left side of the concave plate 501, and a second threaded rod 503 is rotatably connected to the right side of the concave plate 501. One end of the second threaded rod 503 is connected to the first drive motor 504. An anti-slip transmission belt 505 is externally connected to the first threaded rod 502. The first threaded rod 502 is connected to the second threaded rod 503 through the anti-slip transmission belt 505. A moving plate 506 is externally threaded to the first threaded rod 502. One side of the moving plate 506 is connected to the auxiliary sleeve 7. The moving plate 506 is threadedly connected to the outside of the second threaded rod 503.

[0024] By setting an anti-slip transmission belt 505, the first drive motor 504 drives the second threaded rod 503 to rotate. The second threaded rod 503 is connected to the first threaded rod 502 through the anti-slip transmission belt 505, so that the fixing ring 10 above the auxiliary sleeve plate 7 can move evenly and avoid tilting or jamming during the fixing process.

[0025] like Figure 3 and Figure 4 As shown, the rotating rod 604 is rotatably connected inside the support plate 9, the second drive motor 603 is fixedly connected above the support plate 9, the output shaft of the second drive motor 603 is connected to the rotating rod 604, the internal gear 601 is rotatably connected inside the auxiliary sleeve plate 7, the internal gear 601 meshes with the spur gear 602, and the component limiting plate 605 is rotatably connected inside the support plate 9.

[0026] By setting the support plate 9, when the second drive motor 603 drives the component limiting plate 605 to rotate around the spur gear 602, the component limiting plate 605 will drive the rotating rod 604 to rotate within the support plate 9. This allows the support plate 9 to guide the rotation of the component limiting plate 605 and prevent the component limiting plate 605 from bumping or colliding during rotation.

[0027] This utility model provides a CNC machining fixture for automotive parts, the specific working principle of which is as follows:

[0028] When the machining fixture performs positioning processing on automotive parts, specific parts can be placed in the part placement slot 4. Then, the second drive motor 603 drives the part limiting plate 605 to rotate around the spur gear 602. The spur gear 602 meshes with the internal gear 601, which rotates within the auxiliary sleeve 7. The internal gear 601 then drives multiple part limiting plates 605 above the worktable 3 to rotate synchronously. The first drive motor 504 drives the second threaded rod 503 to rotate. The second threaded rod 503 is connected to the first threaded rod 502 via an anti-slip transmission belt 505. The first threaded rod 502 and the second threaded rod 503 rotate synchronously, and the anti-slip transmission belt 505 drives the auxiliary sleeve 7 to slide within the worktable 3, so that multiple part limiting plates 605 within the worktable 3 come into contact with the surface of the automotive parts.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
