Grinding device of rim weld joint

Abstract

The invention discloses a grinding device of a rim weld joint. The grinding device of the rim weld joint comprises a machine box, wherein a flat plate is fixedly connected to one side of the machine box, a first hydraulic cylinder is installed on the flat plate, a hydraulic rod of the first hydraulic cylinder is fixedly connected with a base plate, a vertically-arranged installing plate is fixedlyconnected to the side, facing the machine box, of the base plate, a first rotating shaft is rotationally arranged in the installing plate in a rotating fit manner, a vertically-arranged straight circular groove is formed in one side of the machine box, one end of the first rotating shaft extends into the straight circular groove and can slide up and down in the straight circular groove, and vertical plates are both fixedly connected to the two sides, adjacent to the installing plate, of the base plate. The grinding device has the advantages that the first rotating shaft can rotate in a reciprocating manner to drive an upper scraper to move left and right, a second rotating shaft can rotate in a reciprocating manner to drive a lower scraper to swing, meanwhile, the welding slag of the inner wall and the outer wall of the rim is treated by the lower scraper, a cutter is basically in continuous contact with the welding slag, so that " idle stroke " is basically avoided, and the continuous cutting of the weld joint of the rim is realized.

Description

technical field [0001] The invention relates to the technical field of wheel rim processing equipment, in particular to a wheel rim welding seam grinding device. Background technique [0002] The rim is formed by blanking, rolling, welding and roll forming of steel plates. After the rim is formed, such as Figure 9 As shown, the welding slag 100 at the straight weld will protrude from the surface of the rim, and it is usually processed by a weld cleaning machine. The working principle is: clamp the rim on the welding seam cleaning machine, and drive the rim to rotate through the driving device , and then use the grinding knife to turn the protruding welding slag on the inner and outer surfaces. This method belongs to intermittent cutting. The grinding knife can cut the welding slag once every time the rim rotates, and the rim is rotating , the linear velocity at the welding slag is very fast, so the wear of the grinding knife will be accelerated when the welding slag collid...
