Problems solved by technology

[0002] In the prior art, the broach mechanism mostly uses disc springs or coil springs to provide the broaching force. The broaching force and broaching stroke provided by this structure are limited, and it is inconvenient to adjust. When using different tools, it is difficult To meet various requirements, either set a piston to change the stroke, and change the broach force and stroke by changing the pressure of the piston chamber on both sides of the piston. It is easy to make mistakes during operation, and the applicable tools are limited. When air leakage and other phenomena occur , without a backup solution, the broach mechanism cannot work, reducing production efficiency and low safety

Abstract

A broach mechanism for a tool grinding machine spindle comprises a cylinder body (1), a cylinder body supporting sleeve (2) connected with the cylinder body (1) in a fastened mode, a first piston (3) arranged in the cylinder body (1), a second piston (4) arranged in the cylinder body (1) and a mandrel (8), and the second piston (4) is arranged on the first piston (3) in a sleeved mode and connected with the first piston (3) in a fastened mode. The first piston (3) forms a first piston cavity (5) and a second piston cavity (6) which are not communicated with each other in the cylinder body (1), the second piston forms a third piston cavity (7) in the cylinder body (1), the mandrel (8) is coaxially arranged in the first piston (3) in a penetrating mode, the mandrel (8) can axially move along with the first piston (3), and the mandrel (8) is connected with the first piston (3) in a rotating mode. Different strokes can be provided for different cutters, the structure is simple, and mounting and dismounting are easy.

Description

technical field [0001] The invention relates to the field of tool grinding machines, in particular to a broach mechanism for the main shaft of the tool grinding machine. Background technique [0002] In the prior art, the broach mechanism mostly uses disc springs or coil springs to provide the broaching force. The broaching force and broaching stroke provided by this structure are limited, and it is inconvenient to adjust. When using different tools, it is difficult To meet various requirements, either set a piston to change the stroke, and change the broach force and stroke by changing the pressure of the piston chamber on both sides of the piston. It is easy to make mistakes during operation, and the applicable tools are limited. When air leakage and other phenomena occur , there is no backup plan, the broach mechanism cannot work, the production efficiency is reduced, and the safety is low. Contents of the invention [0003] The object of the present invention is to pr...
