An electrical test device for a broach mechanism

Abstract

The invention provides an electrical testing device for a broaching mechanism. The broaching mechanism includes a cylinder, a first-stage piston, and a connecting body. The electrical testing device includes a signal cap, a signal sensing component, an electronic timer, and a DC power supply. Signal branch, empty knife signal branch, hanging knife signal branch, solenoid valve branch; the signal cap is connected with a pressure measuring device; the knife signal branch is sequentially provided with knife signal access, rotary switches SA4, KA2 constant Close switch, knife signal indicator light, rotary switch SA2 and KA1 normally open switch; empty knife signal access, KA1 normally open switch, empty knife signal indicator are arranged in sequence on the empty knife signal branch; The sequence is equipped with signal access for hanging knife and signal indicator light for hanging knife; the KA1 normally open switch in the knife signal branch is connected with the electronic timer, and the KA2 normally closed switch in the knife signal branch is connected with the electronic timer. The invention is simple and easy to operate, and can accurately feedback the states and reaction times of each action of the broaching mechanism.

Description

technical field [0001] The invention relates to the field of electric spindle machine tools, in particular to an electrical testing device of a broaching mechanism. Background technique [0002] In the actual processing and production of the broaching electric spindle, in order to achieve more efficient processing operations and increase the frequency of rapid tool change during processing, we need to collect detailed data on the response time of the position sensor and the response rate of the tool reset to provide the At the same time, after repeated tool changing operations, it is necessary to measure the change of the broaching force of the broaching mechanism after the actual tool changing frequency, so as to prevent the failure of the broaching mechanism and provide quality assurance for the spindle. The electrical test device installed on the broaching mechanism cannot accurately reflect the working state of the knife, the hanging knife and the empty knife. , the wor...

[0002] In the actual processing and production of broaching electric spindles, in order to achieve more efficient processing operations and increase the frequency of quick tool changes during processing, we need to collect detailed data on the response time of the position sensor and the response rate of the tool reset to provide Production and processing, or to be improved; at the same time, after repeated tool changing operations, it is necessary to make measurement statistics on the changes in the broaching force of the broaching mechanism after the actual tool changing frequency, to prevent the broaching mechanism from failing, and to provide quality assurance for the spindle. The current market The electrical test device installed on the broaching mechanism above cannot accurately reflect the working status of the knife, hanging knife, and empty knife. , the working time of the hanging knife cannot be sensed and counted; the pulling force of the broaching mechanism cannot be tested
