[0030] 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.

[0031] Please see Figures 1-3 In this embodiment of the present invention, a positioning fixture for bearing production and processing includes a worktable 1, a rotating seat 2 rotatably connected to the outer wall of the worktable 1, a positioning seat 3 fixed to the outer wall of the rotating seat 2, and a positioning mechanism 4 disposed on the positioning seat 3.

[0032] Positioning mechanism 4 includes a positioning unit and a limiting unit;

[0033] The positioning unit is used to position the bearing rings of different specifications during loading.

[0034] The limiting unit is used to limit the movement of the positioning unit;

[0035] The positioning unit includes a movable rod 401, a rotating rod 402, a transmission rod 403, a stop block 404, a guide groove 405, and a second spring 409;

[0036] The movable rod 401 is axially slidably sleeved on the outer wall of the rotating rod 402 and is in contact with the inner wall of the positioning seat 3 but not connected. The movable rod 401 is used to synchronously drive the rotating rod 402 to rotate.

[0037] Rotating rods 402 are distributed inside the positioning seat 3, and rotating rods 402 are used to synchronously drive transmission rods 403 to rotate.

[0038] The transmission rod 403 is fixed to the outer wall of the rotating rod 402 by a connecting rod and passes through the abutment block 404. The transmission rod 403 is used to provide vertical moving force to the guide groove 405.

[0039] The abutment 404 is vertically slidably installed on the inner wall of the positioning seat 3 and extends to the outside of the positioning seat 3. The abutment 404 is used to position the bearing ring that is fitted to the outer ring.

[0040] A guide groove 405 is formed on the outer wall of the abutment 404, and the guide groove 405 is used to provide space for the insertion of the transmission rod 403;

[0041] The two ends of the second spring 409 are respectively engaged with the outer wall protrusion of the rotating rod 402 and the inner wall of the positioning seat 3. The second spring 409 is used to provide a restoring force for the rotating rod 402 after rotation.

[0042] The limiting unit includes a positioning block 406, a limiting block 407, and a first spring 408;

[0043] The positioning block 406 is fixed to the outer wall of the movable rod 401 and located inside the positioning seat 3. The positioning block 406 is used to cooperate with the limiting block 407 to limit the rotation of the movable rod 401.

[0044] The limiting block 407 is fixed inside the positioning seat 3 and extends between the two positioning blocks 406. The limiting block 407 is used to limit the rotation of the positioning blocks 406.

[0045] The two ends of the first spring 408 are respectively engaged inside the movable rod 401 and the end of the rotating rod 402. The first spring 408 is used to provide a restoring force for the movable rod 401 after it has been moved.

[0046] In this embodiment, it should be noted that a motor that drives the rotating seat 2 to rotate is installed inside the workbench 1.

[0047] When the outer side of the bearing ring needs to be machined and polished, the bearing ring to be machined is fitted onto the outer wall of the positioning seat 3. The hand is aligned with the center of the bearing ring and contacts the protruding movable rod 401 at the end of the positioning seat 3. Pressure is applied to the movable rod 401. The movable rod 401 under pressure will move along the outer wall of the rotating rod 402 and simultaneously drive the positioning block 406 to move, causing the positioning block 406 to move out of the outer side of the limiting block 407, thereby releasing the movement limitation of the abutment block 404. At this time, the bearing ring will also contact the inclined surface of the outer wall of the abutment block 404 and apply a squeezing force to the abutment block 404. The abutment block 404 under pressure will simultaneously drive the guide groove 405 to move downward. The downward moving guide groove 405 will react and give the transmission rod 403 a squeezing force. The push force causes the transmission rod 403 to transmit the rotational power to the rotating rod 402, which in turn drives the movable rod 401 to rotate and applies a squeezing force to the second spring 409 until the bearing ring is completely fitted onto the outer wall of the abutment block 404. When the pressing force of the movable rod 401 is released, the movable rod 401 will also drive the positioning block 406 to reset under the action of the first spring 408, so that the gap between the two positioning blocks 406 is aligned with the limit block 407, and the rotation of the movable rod 401 is limited again, fixing the position of the abutment block 404, thereby completing the feeding operation of the bearing ring. By starting the motor installed inside the workbench 1, the rotating seat 2 and the positioning seat 3 are driven to rotate, and the bearing ring fitted on the outer side of the positioning seat 3 can be ground.

[0048] Please refer to this carefully. Figures 1-3 There are three transmission rods 403, which are evenly distributed on the outer wall of the rotating rod 402 and pass through three abutment blocks 404. The outer wall of the guide groove 405 is inclined, and the inner cavity of the guide groove 405 matches the cylindrical rod on the outer wall of the transmission rod 403. The outer wall of the rotating rod 402 is fixed with a protrusion that receives the rotational force of the movable rod 401. The inner cavity of the movable rod 401 matches the outer wall of the rotating rod 402. There are multiple positioning blocks 406, which are evenly distributed on the outer wall of the movable rod 401, and the gap between two positioning blocks 406 matches the outer wall of the limiting block 407.

[0049] In this embodiment: With this structure, when it is necessary to unload the finished bearing ring, the movable rod 401 can be pressed by the thumb to release the movable limit of the stop block 404. At this time, the other fingers of the hand can contact the outside of the bearing ring, apply outward pulling force to the bearing ring, and quickly remove the bearing ring for grinding and finishing.

[0050] 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.
