Problems solved by technology

[0003] However, when the traditional three-jaw chuck clamps the outer ring of the bearing, the contact with the outer ring of the bearing is a point contact, which will cause great damage to the bearing ring during clamping and affect the accuracy of the bearing.

Embodiment Construction

[0037] The following is attached Figure 1-6 The application is described in further detail.

[0038] The embodiment of the present application discloses a self-fixing core cladding outer diameter clamp.

[0039] refer to figure 1 , figure 2 , a self-fixing core enclosing outer diameter fixture, including a base 1, a moving seat 2 is slidably arranged on the base 1, and at least three moving seats 2 are arranged along the circumference of the base 1. In this embodiment, the moving seat 2 is set There are three, and they are evenly spaced along the circumference of the base 1 . Each moving seat 2 is provided with two mounting blocks 3, and the mounting block 3 is provided with a clamping block 4 for abutting against the bearing ring. The sidewall away from the center of the bearing abuts.

[0040] refer to figure 2 , image 3The side wall of the mounting block 3 away from the moving seat 2 is provided with a mounting groove 31, and an insertion rod 32 is vertically arr...

Abstract

The invention relates to a self-centering outer diameter wrapping clamp, and belongs to the technical field of bearing machining. The self-centering outer diameter wrapping clamp comprises a base, at least three moving seats are slidably arranged on the base in the circumferential direction of the base, each moving seat is provided with at least two mounting blocks, and the mounting blocks are provided with clamping blocks used for abutting against a bearing ring. A driving source for driving the moving seats to slide is arranged on the base. During working, the movable seats are driven by the driving source to move in the direction close to the bearing ring, so that the clamping blocks abut against the outer side wall of the bearing ring. The multiple movable seats are distributed in the circumferential direction of the base, and each movable seat is provided with at least two clamping blocks, so that the number of stress points of the bearing ring is effectively increased, stress distribution of the bearing ring is more uniform, and the machining quality is improved.

Description

technical field [0001] The present application relates to the technical field of bearing processing, in particular to a self-fixing core cladding outer diameter fixture. Background technique [0002] Bearings are important components in the machinery industry. The precision of bearings directly affects the working conditions of the equipment, which in turn directly affects the quality and life of the equipment. The bearing ring includes an inner ring and an outer ring. When turning the bearing ring, the bearing ring needs to be clamped by a fixture to ensure that the position of the bearing ring is fixed. [0003] However, when the traditional three-jaw chuck clamps the outer ring of the bearing, the contact with the outer ring of the bearing is a point contact, which will cause great damage to the bearing ring during clamping and affect the accuracy of the bearing. Contents of the invention [0004] In order to improve the precision of the bearing ring, the present appli...
