Description

Technical Field

[0001] The utility model relates to the field of products related to bearing production, in particular to a clamp for machining inner and outer rings of adjustable bearings. Background Art

[0002] A bearing is a mechanical element that limits relative motion to a desired range of motion and reduces friction between moving parts. Bearings are designed to provide free linear motion of moving parts or free rotation about a fixed axis, or to prevent motion by controlling the vector of the normal force acting on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings can be broadly classified by type of operation, permitted motion, or direction of load (force) applied to the parts.

[0003] The bearing fixture is used to clamp and fix the bearing to be processed, so that the bearing will not be misaligned during the processing, resulting in poor processing accuracy;

[0004] Existing bearing fixtures can often only be used for bearing inner ring processing or bearing outer ring processing, and can only clamp bearings of a certain size. The clamping size cannot be adjusted in time, and fixtures of different specifications need to be replaced, resulting in low production efficiency and increased production costs. Utility Model Content

[0005] The utility model aims to provide an adjustable fixture for machining inner and outer rings of a bearing, so as to solve the problems raised in the above-mentioned background technology.

[0006] The top end of the supporting plate is fixedly provided with a toothed plate, and the bottom end of the toothed plate is fixedly provided with a toothed plate, and ...

[0007] Preferably, the clamping plate is arranged in an arc-shaped structure, and rubber pads are fixedly connected to the inner wall and the outer wall of the clamping plate.

[0008] Preferably, positioning plates are fixedly connected to both sides of the support box, and fixing screws are inserted at both ends of the positioning plates.

[0009] Preferably, a groove is provided on one side outer wall of the support box, a support rod is fixedly connected in the groove, an L-shaped clamping rod is slidably sleeved on the support rod, and a plurality of clamping grooves corresponding to the L-shaped clamping rod are provided on the rotating block.

[0010] Preferably, the first gear and the second gear are both bevel gears.

[0011] Preferably, the outer side wall of the rotating block is provided with a plurality of anti-slip grooves arranged in an inclined manner.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The clamp for processing the inner and outer rings of the adjustable bearing places the bearing between four clamping plates, and when clamping, the rotating block is rotated clockwise to drive the rotating rod to rotate. At this time, the second gear installed on the rotating rod will mesh with the first gear to realize the rotation of the threaded rod. When the threaded rod rotates, the movable plate threadedly sleeved thereon will follow and move downward, thereby prompting the load-bearing rod to move downward. At this time, the load-bearing rod will drive the connecting plate to slide on the sliding rod and pull the clamping plate to clamp the outer ring of the bearing. The bearing is sleeved on the four clamping plates, and the rotating block can be rotated counterclockwise to realize the clamping plate pressing against the inner ring of the bearing to achieve fixation. The utility model adopts a four-way synchronous motion structure to effectively realize the clamping and fixation of the bearing, and is convenient to adapt to bearings of different specifications.
