Cutting head of bearing ring cutting machine

Abstract

The invention discloses a cutting head of a bearing ring cutting machine, and belongs to the technical field of structural improvement of the bearing ring cutting machine. The cutting head of the bearing ring cutting machine comprises a cutting head body and an auxiliary clamping body, wherein the cutting head body comprises a shell body, an electromotor, a supporting pipe and a workpiece guiding pipe, the shell body, the electromotor, the supporting pipe and the workpiece guiding pipe are arranged in sequence from outside to inside, a plurality of first oil cylinder piston rods are installed in a chamber of the shell body in a matched mode, the rear end of each first oil cylinder piston rod is connected with a rotary disk fixed on a first hydraulic pushing body, the front ends of the first oil cylinder piston rods are communicated with second oil cylinders evenly and fixedly installed at the front end of the shell body through oil ways in a one-to-one correspondence mode, a dragging plate is fixedly installed on a second oil cylinder piston rod in each second oil cylinder, a cutter is installed on each dragging plate, the rear end of the workpiece guiding pipe is connected with a second hydraulic pushing body, the front end of the workpiece guiding pipe is connected with a first inclination elastic collet, the auxiliary clamping body comprises a collet component which is installed in front of the first inclination elastic collet and is arranged opposite to the first inclination elastic collet, and a dimension limiting column is installed on the inner side of the collet component. The cutting head of the bearing ring cutting machine is high in cutting precision.

Description

technical field [0001] The invention discloses a cutting head of a bearing ring cutting machine, which belongs to the technical field of structural improvement of the bearing ring cutting machine. Background technique [0002] The existing bearing ring cutting machine mainly has the following defects in the rings cut out: there are burrs on the two end faces of the ring, which need to be finished in the later stage for deburring; the height and dimension of the ring are unstable, and the parallelism between the two end faces of the ring The degree is not good, and it needs to be flat ground after finishing. At the same time, the arc surface cannot be directly processed on the outer circle of the ferrule, but needs to be placed on other arc processing equipment for additional processing. In short, for the rings cut by the existing bearing ring cutting machine, the post-processing procedures are cumbersome, the processing accuracy is low, and the production cost is high. Co...

[0002] The existing bearing ring cutting machine mainly has the following defects in the rings cut out: there are burrs on the two end faces of the ring, which need to be finished in the later stage for deburring; the height and dimension of the ring are unstable, and the parallelism between the two end faces of the ring The degree is not good, and it needs to be finished for flat grinding in the later stage

At the same time, the arc surface cannot be directly processed on the outer circle of the ferrule, but needs to be placed on other arc processing equipment for additional processing

In short, the post-processing of the rings cut by the existing bearing ring cutting machine is cumbersome, the processing accuracy is low, and the production cost is high.
