[0021] This application provides a rotary fixture for machining parts, which solves the technical problem that existing fixtures, due to their simple structure, cannot adjust the angle of the parts again after clamping and fixing them, thus limiting their practical application and making it difficult to meet machining requirements.

[0022] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] A rotary fixture for machining parts, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a base plate 1, a support plate 2 for supporting components, a positioning device 3 for positioning components, an annular plate 4 located at the bottom of the support plate 2, an internal gear 5 located inside the annular plate 4, an arc-shaped slider 6 for supporting the annular plate 4, an annular slide rail 7 for limiting the sliding of the arc-shaped slider 6, and a rotating device 8 mounted on the base plate 1. Several sets of positioning devices 3 arranged in a circular array are mounted on the support plate 2. Several sets of arc-shaped sliders 6 arranged in a circular array are connected to the bottom of the annular plate 4. Each set of arc-shaped sliders 6 slides on the annular slide rail 7. The rotating device 8 is driven by the internal gear 5. The annular slide rail 7 is located on the base plate 1.

[0025] The rotating device 8 includes an external gear 81 and a drive device 82 mounted on the top of the base plate 1. The external gear 81 is mounted on the output shaft of the drive device 82. The external gear 81 meshes with the internal gear 5.

[0026] The positioning device 3 includes a T-shaped plate 31, a fixing member 32 for fixing the T-shaped plate 31, a baffle 33 for abutting against the component, and a threaded rod 34 threadedly connected to the top of the T-shaped plate 31. The T-shaped plate 31 is fixedly installed on the top of the base plate 1 by the fixing member 32. The baffle 33 is provided at one end of the threaded rod 34.

[0027] The positioning device 3 also includes a rubber pad 35. The rubber pad 35 is disposed on the baffle 33.

[0028] The positioning device 3 also includes a bending handle 36. The bending handle 36 is located at the other end of the threaded rod 34.

[0029] The fastener 32 is a bolt. The top of the support plate 2 has several sets of threaded holes arranged in a circumferential array and adapted to the fastener 32.

[0030] The drive unit 82 is a servo motor.

[0031] A positioning center line 21 is provided at the top center of the support plate 2.

[0032] The base plate 1 is made of cast iron with bolt holes for fixing the fixture. The support plate 2 is a circular aluminum alloy plate with a positioning center line 21 engraved at the top center for quick alignment of components. The annular plate 4 is welded to the bottom of the support plate 2, and the internal gear 5 is fixed to the inside of the annular plate 4 with bolts. The annular slide rail 7 is a hardened steel rail, fixed to the top surface of the base plate 1 with countersunk screws. The arc-shaped slider 6 is a copper-based self-lubricating slider, consisting of three sets, arranged in a circumferential array and fixedly connected to the annular plate 4, slidingly engaging with the annular slide rail 7. The drive device 82 is preferably a servo motor, fixed to the top of the base plate 1 via a base. The external gear 81 is mounted on the output shaft of the drive device 82, and meshes with the internal gear 5 to achieve precise indexing rotation of the support plate 2. The bottom of the T-shaped plate 31 is locked in the circumferential array of threaded holes of the support plate 2 by fasteners 32 (bolts), and its position is adjustable. A threaded rod 34 passes through a threaded hole at the top of the T-shaped plate 31. The clamping distance of the baffle 33 is adjusted by hand-tightening the threaded rod 34. A rubber pad 35 is bonded to the surface of the baffle 33 to prevent scratching the parts. A bent handle 36 is welded to the end of the threaded rod 34 for easy manual adjustment.

[0033] Working process: Place the part to be processed in the center of the support plate 2 and position it using the positioning center line 21. Tighten the bending handle 36 to drive the threaded rod 34 to rotate, causing the baffle 33 to clamp the part. When it is necessary to adjust the angle of the part, start the drive device 82, which drives the external gear 81 to rotate the internal gear 5. The support plate 2 rotates along the annular slide rail 7 via the arc-shaped slider 6, thus adjusting the angle of the part. After the part is processed, rotate the threaded rod 34 in the opposite direction to release the part and reset the fixture.

[0034] The system employs a base plate 1, support plate 2, positioning device 3, annular plate 4, internal gear 5, arc-shaped slider 6, annular slide rail 7, and rotating device 8. Through the meshing transmission of the internal gear 5 and external gear 81, and the guidance of the annular slide rail 7, the support plate 2 achieves 360° continuous rotation, resulting in an angle adjustment accuracy of ±0.5°, meeting complex machining requirements. The annular slide rail 7 and arc-shaped slider 6 are made of a combination of hardened steel and self-lubricating copper-based materials, reducing the coefficient of friction and minimizing rotational wobbling. The three sets of sliders in a circumferential array evenly distribute the load, preventing the support plate 2 from tilting. The positioning center line 21, in conjunction with the adjustable T-shaped plate 31, shortens clamping time. Rubber pads 35 provide flexible contact, preventing damage to the surface of precision parts. Because the T-shaped plate 31 can be quickly replaced with bolts, it can accommodate parts of different sizes.
