Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a machining and positioning fixture for self-lubricating bearings, such as... Figures 1-4 As shown, the machining and positioning fixture for the self-lubricating bearing includes a fixture body 1. A placement cavity 2 is provided in the upper end of the fixture body 1. A first screw 3 is rotatably installed in the fixture body 1. A screw sleeve 4 is threaded onto the first screw 3. Multiple sets of connecting rods 5 are rotatably installed on the screw sleeve 4. A slider 6 is rotatably installed on the upper end of each set of connecting rods 5. A first clamping plate 7 is fixedly installed on the upper side of each set of sliders 6. An mounting plate 8 is fixedly installed in the fixture body 1. Multiple sets of guide grooves 9 are provided on the mounting plate 8. Multiple sets of sliders 6 are slidably inserted into the multiple sets of guide grooves 9. A locking component for clamping the outer wall of the bearing is provided in the guide grooves 9.

[0023] During use, the self-lubricating bearing to be processed is first placed in the fixture. By manually rotating the first screw 3, the first screw 3 rotates within the fixture body 1 and drives the screw sleeve 4 to move up and down through the thread. The movement of the screw sleeve 4 will drive the multiple sets of connecting rods 5 mounted on it to move synchronously. The movement of the connecting rods 5 will further drive the multiple sets of sliders 6 and multiple sets of first clamping plates 7 to slide in the multiple sets of guide grooves 9 opened on the mounting plate 8, thereby fitting and limiting the bearing inner wall. At this time, the locking component is activated to clamp and fix the bearing outer wall.

[0024] The locking assembly includes a motor 10, which is fixedly installed inside the fixture body 1. A first bevel gear 11 is fixedly installed on the output shaft of the motor 10. A second bevel gear 12 is rotatably installed inside the fixture body 1. A bidirectional screw 13 is rotatably installed inside the fixture body 1. The second bevel gear 12 is fixedly connected to the bidirectional screw 13. Slide grooves 14 are symmetrically opened on the left and right sides inside the fixture body 1. Moving rods 15 are threadedly connected to both ends of the bidirectional screw 13. A second clamping plate 16 is fixedly installed on the upper end of both sets of moving rods 15.

[0025] The motor 10 starts and drives the first bevel gear 11 on its output shaft to rotate. The rotation of the first bevel gear 11 will drive the second bevel gear 12, which is fixedly connected to it, to rotate synchronously. Since the second bevel gear 12 is fixedly connected to the bidirectional screw 13, the bidirectional screw 13 will also rotate. The rotation of the bidirectional screw 13 will drive the moving rods 15 connected by threads at its left and right ends to move on the bidirectional screw 13, thereby driving the two sets of second clamping plates 16 to move closer to the outer wall of the bearing until the outer wall of the bearing is clamped and fixed.

[0026] The surfaces of the multiple sets of first clamping plates 7 and the two sets of second clamping plates 16 are all arc-shaped. The two sets of second clamping plates 16 are arranged parallel to the connecting rods 5, sliders 6 and first clamping plates 7 on the left and right sides of the screw sleeve 4.

[0027] This design allows the tooling to better conform to the shape of the bearing when clamping it, improving the stability and accuracy of clamping. At the same time, the arc design can reduce the friction between the tooling and the bearing, reduce the damage to the bearing surface caused by the tooling, and thus protect the surface quality of the bearing.

[0028] A third bevel gear 17 is fixedly installed at the lower end of the first screw 3, and the third bevel gear 17 meshes with the second bevel gear 12.

[0029] The locking assembly is driven by the third bevel gear 17, thereby enabling synchronous clamping and fixing of the inner and outer walls of the bearing.

[0030] The two sides of the multiple sets of sliders 6 and the two sets of second clamping plates 16 are all glued with anti-slip pads.

[0031] The anti-slip pad increases the friction between the tooling and the bearing, preventing the bearing from sliding or rotating during machining, and further improving the clamping stability of the tooling and the machining accuracy.

[0032] Multiple sets of positioning plates 18 are fixedly installed on the lower inner wall of the placement cavity 2, and each set of positioning plates 18 has a positioning groove 19.

[0033] The multiple sets of positioning plates 18 and multiple sets of positioning grooves 19 are used for positioning during bearing clamping.

[0034] Working principle: In use, the self-lubricating bearing to be processed is first placed on the placement cavity 2 of the tooling. The lower end of the bearing contacts multiple sets of positioning plates 18 and is initially positioned by the positioning grooves 19 opened on the positioning plates 18. At this time, the motor 10 in the locking assembly is started. The motor 10 responds quickly and drives the first bevel gear 11 on its output shaft to rotate. The rotation of the first bevel gear 11 is transmitted to the second bevel gear 12 fixedly connected to it. Since the second bevel gear 12 is fixedly connected to the bidirectional screw 13, the bidirectional screw 13 will also rotate synchronously. The rotation of the bidirectional screw 13 further drives the moving rods 15 at its left and right ends, which are connected by threaded sleeves, to rotate in a double-ended manner. As the screw 13 moves, the two sets of moving rods 15 move closer together, thereby driving the two sets of second clamping plates 16 to gradually approach the outer wall of the bearing until a stable clamping and fixing is formed on the outer wall of the bearing. Subsequently, the second bevel gear 12 rotates while driving the first screw 3 to rotate. The first screw 3 rotates smoothly in the tooling body 1 and drives the screw sleeve 4 to move up and down along the axial direction of the first screw 3 through the threaded structure. The movement of the screw sleeve 4 will drive the multiple sets of connecting rods 5 mounted on it to move synchronously. The connecting rods 5 then push the multiple sets of sliders 6 and the multiple sets of first clamping plates 7 to slide smoothly in the multiple sets of guide grooves 9 opened on the mounting plate 8 until they are tightly fitted with the inner wall of the bearing, thereby achieving the limitation of the inner wall of the bearing.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
