Description

A center hole grinding device

technical field

The invention mainly relates to the technical field of gear shaft processing, in particular to a central hole grinding device.

Background technique

The gear shaft needs to go through multiple processes during the machining process, mainly including blank blanking, rough turning, quenching and tempering treatment, fine turning of the gear blank to size, if there is a keyway on the shaft, the keyway can be processed first, hobbing, tooth surface Intermediate frequency quenching, quenching hardness HRC48-58, gear grinding, final inspection of finished products.

In the above process, it is also necessary to carry out drilling at both ends of the gear shaft, which is the processing benchmark for subsequent grinding of the outer circle and gear hobbing, as well as the inspection benchmark for the accuracy of grinding the outer circle and gear hobbing. After the drilling is completed, the center There are bumps in the hole, and after carburizing and quenching, some semi-finished products have oxide scales in the positioning center hole, which needs to be removed at the positioning center hole.

At present, vertical machine tools can be used to grind the center holes at both ends. The specific process is to enter the center hole through the top grinding tip for grinding.

The inventor found the following defects during the operation of the specific embodiment:

Although the grinding machine improved by the vertical machine tool can effectively rub off the excess skin on both sides of the two center holes, the body of the grinding tip will also be damaged after working for a long time. At this time, the grinding tip needs to be removed for grinding During operation, or on the workbench during the grinding operation, the disassembly and grinding process is more complicated. If you want to grind on it, you need a hand-held tool to grind the grinding tip, which is inconvenient and difficult to control due to low precision.
