Description

Technical Field

[0001] The utility model relates to the technical field of bearing flange processing, in particular to a clamp structure for simultaneously positioning a plurality of linear bearing flanges. Background Art

[0002] The series of products with flanges on the outer wheel make axial positioning simple; bearing seats are no longer needed, making it more economical. In order to obtain low friction torque, high rigidity and good rotation accuracy of the bearing, small outer diameter steel balls are used. The use of hollow shafts ensures lightweight and wiring space. When processing the bearing flange, a fixture structure that can simultaneously position multiple linear bearing flanges is required for fixing.

[0003] With reference to the Chinese patent application number "CN220740896U" of "A fixture structure for bearing production and processing", the utility model discloses a fixture structure for bearing production and processing, including a base, two symmetrically arranged clamps are arranged on the base, a limiting area for fixing the bearing is formed between the two clamps, and a power component for driving the two clamps to rotate and control the closing and opening of the limiting area is arranged at the ends of the two clamps. The moving block moves in the groove, and under the rotation of the rotating shaft, the two connecting plates are opened outward at one end close to the clamps, and the two clamps are driven to move by the vertical rod, so that the limiting area is opened. At this time, the bearing to be processed is placed in the limiting area, and after reversing the threaded rod, the moving block moves toward the support seat, and the two clamps are close to each other, closing the limiting area, allowing the bearing to abut against the inner wall of the clamp, so as to achieve the clamping and fixing of the bearing, which is convenient for later processing. The overall structure is simple and the practicality is improved.

When the bearing surface needs to be processed, the fixture structure cannot be used and has low applicability. To this end, we propose a fixture structure for simultaneously positioning multiple linear bearing flanges to solve the above problems. Utility Model Content
