Description

Technical Field

[0001] The utility model belongs to the field of bearing processing and positioning equipment. Specifically, it particularly relates to a pre-positioning mechanism for grinding the outer ring of a bearing. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. During the production and processing of bearings, it is necessary to further grind the inner and outer ring surfaces of the cast bearing rings to improve the accuracy of the bearings. When grinding large-diameter bearing rings, due to the large volume and weight of the bearing rings, the bearing rings are generally placed flat and fixed on the processing platform. As a result, during grinding, the processing platform is likely to interfere with the grinding equipment, making it inconvenient to grind the inner and outer ring surfaces of the bearing rings. Therefore, after the upper side of the inner and outer ring surfaces of the bearing ring is ground, it is necessary to turn the bearing over, set the unprocessed side upward, and then perform grinding, which makes the processing steps of the bearing ring rather cumbersome, the processing efficiency is low, and it is also inconvenient to grind the inner and outer ring surfaces of the bearing ring when placed flat. Content of the Utility Model

[0003] In view of the problems in the related art, the utility model proposes a pre-positioning mechanism for grinding the outer ring of a bearing to overcome the above-mentioned technical problems existing in the prior related art.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a pre-positioning mechanism for grinding the outer ring of a bearing, including a mounting base. A support base is fixedly installed at the upper end of the mounting base. A translation and lifting adjustment bracket is installed on the support base. Cross beams are fixedly installed on both sides of the top of the translation and lifting adjustment bracket. A positioning block is fixedly installed on the front side of the cross beam. An elastic telescopic member is fixedly installed on the front side of the positioning block. A butt-joint positioning member is installed at the front end of the elastic telescopic member.

[0006] Further, the translation and lifting adjustment bracket includes a horizontal adjustment rod, which is slidably inserted and connected with the support base. One end of the horizontal adjustment rod is fixedly installed with an adjustment seat. A lifting adjustment rod is slidably inserted into the adjustment seat. The top end of the lifting adjustment rod is fixedly installed with a vertical adjustment rod. A clamping sleeve is installed on the vertical adjustment rod. Cross beams are fixedly installed at both ends of the clamping sleeve.

[0007] Further, positioning rings are fixedly installed at one ends of the support base and the adjustment seat. A bolt capable of adjusting the opening degree of the positioning ring is installed on one side of the positioning ring. A bolt capable of adjusting the clamping force of the clamping sleeve is installed on one side of the clamping sleeve.

[0008] Further, the elastic telescopic member includes a spring seat fixedly installed on the front side of the positioning block. A compression spring is installed inside the spring seat.

One end of the sliding sleeve is fixedly installed with a telescopic frame, and the abutting positioning member is installed at the front end of the telescopic frame.

[0009] Further, the abutting positioning member is a deep groove ball bearing. A pin shaft is rotatably installed at the front end of the telescopic frame, and the abutting positioning member is installed on the pin shaft.

[0010] Further, a waist slot is formed in the cross beam, and the spring seat is locked and fixed to the front side of the cross beam through a bolt passing through the waist slot.

[0011] The utility model has the following beneficial effects:

[0012] 1. When the large-diameter bearing ring is ground in the utility model, the two end faces of the bearing ring can be tightly abutted and fixed by the front positioning mechanism and the corresponding rear positioning mechanism, so that the bearing ring is erected and fixed on the processing platform. And the positioning mechanism abuts and fixes the bearing ring by the abutting method of multiple abutting positioning members, so that the contact area between the positioning mechanism and the bearing ring is small, and it is not easy to interfere with the use of the grinding equipment. Thus, it is convenient for the grinding equipment to grind the inner and outer ring surfaces of the bearing ring, so as to improve the grinding efficiency of the bearing ring. And after the grinding process, the erected bearing ring can be rotated, so as to facilitate the comprehensive grinding of the inner and outer ring surfaces of the bearing ring.

[0013] 2. In the utility model, the abutting positioning member is installed through the translation and lifting adjustment bracket, and the positions of the abutting positioning member in the front-back, left-right and up-down directions can be adjusted, so as to facilitate the abutting positioning of bearing rings with different diameters. And the abutting positioning member is installed through the elastic telescopic member. When the abutting positioning member abuts against the end face of the bearing ring, the elastic telescopic member can be telescoped and buffered to prevent the rigid abutting and collision between the abutting positioning member and the bearing ring, which may cause damage to the abutting positioning member or the bearing ring. At the same time, the abutting positioning member adopts a deep groove ball bearing. When the bearing ring rotates during grinding, the outer ring of the deep groove ball bearing can rotate synchronously, so as to prevent the wear of the bearing ring and the abutting positioning member.

[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Brief Description of the Drawings
