Abstract

The invention discloses an automatic measurement and control circuit for drill bit test, which controls the drilling and lifting actions, the moving actions of the hole positions of a test piece, thesetting of the hole number and hole spacing in the X-axis and Y-axis directions, the drilling time measurement and the printing output. The measurement and control circuit is composed of a power supply, a single chip microcomputer, an electric drill and cylinder control circuit, a cross slide movement control circuit, a hole number and hole spacing setting circuit, a drilling time measurement circuit and a printing output circuit which are connected in a circuit manner. The automatic measurement and control circuit is applied to the measurement and control of sharpness and wear resistance (life) of twist drills or impact drills, is applicable to the test of drill bits with different thickness and length, realizes an automatic drill bit test process, and has good universality.

Description

technical field [0001] The invention relates to a measurement and control circuit of a drill bit test bench, in particular to an automatic measurement and control circuit applied to a drill bit sharpness and wear resistance (life) test bench. Background technique [0002] The sharpness and wear resistance (life) of the drill bit depend on the material, heat treatment and manufacturing process of the drill bit, which are two important indicators to measure the performance of the drill bit, and are the quality inspection and test items that manufacturers or quality supervision departments must do. Traditional testing is done manually, which is not only cumbersome and time-consuming, but also only depends on the feeling and subjective judgment of the testers, and the results are not accurate enough. Contents of the invention [0003] The purpose of the present invention is to provide an automatic measurement and control circuit for drill bit testing, which is applied to the m...
