Turning tool geometric angle measurement test bench

Abstract

The invention discloses a geometric angle measuring experiment table for lathe tools. The geometric angle measuring experiment table comprises an experiment table support portion, a guide portion, a measuring portion and a control portion. The experiment table support portion comprises an experiment table base and an experiment table cushion block, and the experiment table cushion block is positioned on the experiment table base and is connected with the experiment table base by screws; the guide portion comprises an X-direction guide device and an Z-direction guide device. A second shaft can be driven by placement locations of test pieces on tools or clinging locations of test surfaces of the second shaft and cutting edges to rotate, a second toothed belt wheel can be driven by the second shaft to rotate, a toothed belt can be driven by the second toothed belt wheel to rotate, a first toothed belt wheel can be driven by the toothed belt to rotate, an angle sensor shaft can be driven by the first toothed belt wheel to rotate, and analog quantities can be outputted by an angle sensor, so that angles can be measured. The geometric angle measuring experiment table has the advantages that the analog quantities outputted by the angle sensor can be converted into digital quantities by an analog-digital conversion module, accordingly, ultimate angle values can be inputted into an LED display, and measurement persons can directly read the angle values without estimated reading or computing.

Description

Technical field [0001] The present invention relates to an experimental device for measuring the geometric angle of a turning tool used in the professional course of "Machinery Manufacturing Technology Fundamentals". More specifically, the present invention relates to an experimental device that can measure the geometric angle of a turning tool, digitally read the measurement data and perform A teaching experiment platform for data access and measurement results comparison. Background technique [0002] The professional course "Machinery Manufacturing Technology Fundamentals" is a compulsory professional course for engineering students. The content involved in the course is highly professional and theoretical, which lays a theoretical foundation for working or continuing to study after the birthday of engineering. The experimental courses offered during the period provided students with the ability to operate. The development of experimental classes can not only deepen students'...

Problems solved by technology

However, due to the use of the test bench for many years, the test bench now has defects such as corrosion, nicks, and blurred lines.

Moreover, the currently used test bench obtains the measured angle value through the visual inspection of the surveyor and artificially reads the data on the dial. The measurement result has a large error from the real value. Development does not match, resulting in undergraduate teaching seriously lagging behind the development of science and technology
