[0018] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.
[0019] This application discloses an adjustable positioning fixture for bearing machining. (Refer to...) Figures 1-3 An adjustable positioning fixture for bearing processing includes a base 1, with supports 2 on both sides of the top of the base 1. A connecting frame 3 is provided between the two supports 2, and two positioning frames 4 are provided on the connecting frame 3. A moving component is also provided to drive the two positioning frames 4 to move closer or further apart simultaneously. The moving component includes a slide rail 16, a connecting rod 17, a slider 18, a slide rail 29, a cylinder 20, and a mounting bracket 21. The slide rail 16 is fixed to the bottom of the connecting frame 3, and the positioning frames 4 can slide on the surface of the slide rail 16. One end of the connecting rod 17 is connected to the positioning frame. 4. The bottom is hinged, and the other end of the connecting rod 17 is hinged to the bottom of the slider 18. The mounting bracket 21 is fixed to the bottom of the connecting bracket 3. The cylinder 20 is fixed on the mounting bracket 21. The telescopic end of the cylinder 20 is fixed to one side of the slider 18. The second slide rail 19 is fixed to the bottom of the connecting bracket 3 and is set perpendicular to the first slide rail 16. The slider 18 slides on the surface of the second slide rail 19. The cylinder 20 is activated to push the slider 18 to slide on the second slide rail 19. Under the connection of the connecting rod 17 and the guidance of the first slide rail 16, the two positioning brackets 4 move closer or further apart.
[0020] Reference Figures 1-3Both positioning frames 4 are equipped with clamping plates 1-6 and 2-10 on their tops, as well as an adjustment assembly that simultaneously drives clamping plates 1-6 and 2-10 to swing. The adjustment assembly includes gear 1-5, gear 2-9, a fixed frame 12, and a motor 13. Gear 1-5 and gear 2-9 rotate on the top of the positioning frame 4. Clamping plate 1-6 is fixed to the top of gear 1-5, and gear 2-9 is fixed to the top of clamping plate 2-10. Gear 1-5 meshes with gear 2-9. Fixed frame 12 is fixed to the top of the positioning frame 4, and motor 13 is fixed to the top of fixed frame 12. The rotor end of motor 13 is fixed to clamping plate 1-6. Sliding posts 7 are provided at the bottom of clamping plates 1-6 and 2-10. The top of the positioning frame 4 has guide grooves 1-8 and 2-11 for sliding posts 7. Guide groove 1-8 is concentric with the cross-section of gear 1-5, and guide groove 2-11 is concentric with the cross-section of gear 2-9. The motor 1-1 is started. 3. Rotate clamping plate 6 and gear 5. Under the guidance of guide groove 8, sliding column 7 at the bottom of clamping plate 6 slides in guide groove 8, causing clamping plate 6 to swing along the axis of gear 5. Under the meshing action of gear 5 and gear 9, gear 5 rotates and drives gear 9 and clamping plate 10 above it to swing synchronously. Sliding column 7 at the bottom of clamping plate 10 slides in guide groove 11, causing clamping plate 10 to swing along the axis of gear 9. This allows for adjustment of the angle between clamping plate 6 and clamping plate 10, which can closely fit the bearing surface of different shapes, enhancing the stability of positioning and the accuracy of processing. At the same time, it can clamp and position bearings of different sizes and specifications, and can handle multi-variety, small-batch production tasks without frequent fixture changes, effectively improving the production efficiency and flexibility of bearing processing.
[0021] Both clamping plate 6 and clamping plate 10 are equipped with positioning pins 15 on their tops. In order to further improve the applicability of bearing clamping and positioning, clamping plate 6 and clamping plate 10 can also be used as bearing placement seats during processing, so that the positioning pins 15 are located in the inner ring of the bearing, and can be used to position bearings with different inner diameters as the positioning frame 4 moves.
[0022] Reference Figure 1 A rubber pad 14 is provided on the side of clamping plate 6 and clamping plate 10 that are close to each other. This prevents clamping plate 6 and clamping plate 10 from directly contacting the bearing parts and causing damage to the surface of the bearing parts. At the same time, it can increase the clamping friction and improve the clamping stability.
[0023] Reference Figure 3 A limiting plate 22 is provided on the side of the base 1 away from the cylinder 20, which is used to limit the sliding of the slider 18.
