Description

Technical Field

[0001] The utility model relates to the technical field of bearing turnover, in particular to a turnover fixture for bearing processing. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. The production process of the bearing ring includes forging, heat treatment, grinding inspection and identification management. During the processing, the bearing ring needs to be clamped and turned by a fixture, and then the bearing ring needs to be polished on both sides by a grinding device.

[0003] For example, the prior art application number CN202221961778.5 discloses a turning fixture for grinding a bearing ring, comprising a processing table and a group of L-shaped mounting plates movably mounted above the processing table, a group of L-shaped mounting plates having a turning mechanism connected to the rear end, a group of L-shaped mounting plates having clamping mechanisms respectively arranged, the turning mechanism comprising a vertical mounting plate, an electric push rod 1, a push plate, a fixed slide rail, a sliding plate, a bar-shaped rack, a group of fixed seats and a group of rotating shafts, the clamping mechanism comprising a group of electric push rods 2, a group of fixed sleeves, a group of clamping bottom plates, a group of triangular connecting plates, two groups of clamping claws and two groups of connecting rods;

[0004] The above technical solution is known through actual use. When in use, the bearing is placed between the placement groove and the clamping claw, and then the bearing is clamped. However, after long-term use, it is found that the opening of the placement groove always remains unchanged, which causes the placement of the bearing to be limited during use. If a large-diameter bearing is forcibly placed, the clamping will become loose, and most bearings of different diameters cannot be placed, resulting in reduced adaptability and inconvenience in bearing processing.

The upper end of the movable rod 6 is rotatably connected to the support plate 5 through a pin rod, and the lower end of the movable rod 6 is also rotatably connected to the clamping grip 7 through a pin rod. The top bending part of the clamping grip 7 is rotatably connected to the front side of the support plate 5 through a pin. By starting the cylinder 3 to pull or push the triangular plate 4 and the movable rod 6, the two clamping grips 7 are closed or expanded.

[0023] refer to Figures 2 to 4 In the present application, the inner sides of the two clamps 7 near the bearing body 9 are fixedly connected with rubber plates 13 by bolts, and one side of each rubber plate 13 is pressed against the outer periphery of the bearing body 9. The front side of the bottom plate 10 is fixedly connected with a mounting block 801, and a bidirectional screw 802 is rotatably mounted on the mounting block 801. A side slide groove 11 is provided inside the outer side of the bottom plate 10, and a through groove 12 is also provided inside the front side of the bottom plate 10. The through groove 12 is connected with the side slide groove 11. A stopper 805 is slidably installed in the side slide groove 11, and a connecting block 804 is provided through the through groove 12. The two stoppers 805 are arranged in a V shape, and the inner sides of the stoppers 805 are pressed against the outer periphery of the bearing body 9.

[0024] Through the above technical solution, the screw sleeve 803 drives the connecting block 804 to move in the through groove 12, and the block 805 slides in the side slide groove 11, which is used to ensure the stability of the block 805 and reduce the movement resistance. The inner side of the block 805 is sprayed with rubber paint to achieve soft contact between the block 805 and the bearing body 9, reduce the wear on the bearing body 9, and better protect the bearing body 9.

[0025] Working principle of a flip fixture for bearing processing:

[0026] First, place the bearing body 9 between the clamp 7 and the two stoppers 805, start the cylinder 3 to pull the triangular plate 4 upward to drive the movable rod 6 to move, and pull the two clamps 7 inward to clamp the bearing body 9 through the movable rod 6. On the contrary, the cylinder 3 pushes to release the clamping of the bearing body 9. After the bearing body 9 is clamped, start the servo motor 2 to drive the cylinder 3, the support plate 5 and the clamp 7 to rotate, so as to drive the bearing body 9 to flip;

[0027] Before placing the bearing body 9, the two-way screw 802 in the adjustment assembly 8 can be rotated to make the two screw sleeves 803 relatively move away from each other. The screw sleeve 803 will drive the two blocks 805 to move away from each other through the connecting block 804. The distance between the two blocks 805 will become larger, and the V-shaped opening between the two blocks 805 will become larger, which can accommodate the placement of most larger diameter bearing bodies 9. Conversely, rotating the two-way screw 802 in the opposite direction will shorten the distance between the two blocks 805 and reduce the V-shaped opening, so that a smaller bearing body 9 can be placed.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
