Abstract

The invention relates to an automatic test device of the flatness and thickness of a metal sheet, which comprises a machine frame, a feeding mechanism, a test platform and a discharging mechanism. The machine frame and the test platform are connected through a Y-directional track. The test platform comprises a test frame, guide rails, a test cross beam, a cantilever fixing frame, a cantilever, an upper test probe, a lower test probe, a Y-directional ball screw mechanism and a measuring circuit. The automatic test device has the following beneficial effects that: the test is accurate; the test efficiency and the test precision are improved because the probes always cover the effective test range of a saw blade; mechanical and electrical integration technology is fully used, the structure is simple, the operation and maintenance are convenient, and the application in the field of the test of the flatness and thickness of other metals can be realized with a little improvement, and the promotion and use are easy; and an eddy induction principle is used to realize the test of the flatness and the thickness of the metal sheet, the interference of water and other non-metal impurities on the saw blade is eliminated effectively, precise positioning of the saw blade is not required in test, the price is low, and the operation is simple.

Description

technical field

[0001] The invention relates to an automatic detection device for the flatness and thickness of a thin metal plate. Background technique

[0002] At present, enterprises that produce metal saw blades or alloy saw blades used in woodworking and mining fields mostly use laser-type flatness and thickness testers, three-dimensional coordinate testers or manual devices for on-line inspection or final inspection of products. Micrometer to test. Laser-type flatness and thickness testers are expensive, and saw blades with water and debris cannot be tested during the test. However, the operation of the three-dimensional coordinate tester is complicated, the test speed is extremely slow, the price is extremely expensive, and it is generally impossible to perform fully automatic testing, so it is difficult to popularize. The human error of the manual test method is relatively large, and the test results are not reliable enough. Moreover, the operating area measured by...
