Device for milling left bearing pedestal and right bearing pedestal

Abstract

The invention discloses a device for milling a left bearing pedestal and a right bearing pedestal, and belongs to the field of machining. The device comprises a support, a positioning sleeve and a limiting pin; the positioning sleeve is of a circular ring structure and is mounted on the support; the outer diameter of the positioning sleeve is equal to or slightly smaller than the inner diameter of a left bearing and a right bearing; a first limiting hole is formed in the position, corresponding to a through hole of the left bearing pedestal to be machined and the right bearing pedestal to be machined, of the positioning sleeve, and a second limiting hole is formed in the position, symmetric with the first limiting hole, of the positioning sleeve; the limiting pin is used for being inserted into the through hole of the left bearing pedestal to be machined and the right bearing pedestal to be machined and the limiting holes of the positioning sleeve, and therefore positioning of the left bearing pedestal to be machined and the right bearing pedestal to be machined on the positioning sleeve is achieved; and reliable and stable supporting can be formed on the left bearing pedestal to be machined and the right bearing pedestal to be machined, positioning is accurate, mounting is convenient, the production efficiency of the left bearing pedestal and the right bearing pedestal can be effectively improved, and the product machining precision is ensured.

Description

technical field [0001] The invention relates to a processing tool for a left and right bearing seat, specifically a device for milling a left and right bearing seat, belonging to the field of mechanical processing. Background technique [0002] The left and right bearing housings are key parts in the central transmission mechanism of bulldozers, such as figure 1 shown. The upper and lower symmetrical directions of the left and right bearing seats are respectively provided with a keyway and a notch, and both have symmetry requirements with the through holes on the left and right bearing seats. In the trial production stage, when the milling machine is processed, the dividing head is used to clamp, and then the keyway and the notch are processed. The calibration is troublesome, the clamping is not reliable, and the processing operation is affected, which in turn affects the accuracy of the finished product. The quality is not easy to guarantee. At the same time, the processi...
