Abstract

The invention discloses a flatness tester for a high-precision metal sheet. The flatness tester comprises a base, extension blocks are symmetrically and fixedly arranged at a left side and a right side of the base, a lifting plate is arranged at an upper side of the base, a top space with a downward opening is arranged at a bottom side of the lifting plate; pigment is firstly added from a throughhole, and then an L-shaped plate is pulled to two sides, and then an entering plate can be placed between cushions, and then the L-shaped plate is released. The device can perform flatness testing onthe processed metal sheet; compared with the simple spirit level, the device can obtain irregular point or line or surface through the measurement; compared with the expensive laser detector, the device disclosed by the invention is not only low in cost, the irregular surface or point can be found out, and the irregular surface or point can be marked through the pigment.

Description

technical field

[0001] The invention relates to the field of material detection, in particular to a flatness tester for high-precision metal plates. Background technique

[0002] With the development of the times, the level of machining is getting higher and higher. After machining a metal plate, it is often necessary to test its flatness. During the test, the ordinary level can only roughly test the metal plate. Whether the angle of the metal plate is 180 degrees, it is impossible to measure whether each point on the metal plate is flat, and although a professional laser detector can measure whether each point on the metal plate is flat, but its cost is expensive, and in the measurement Finally, it is impossible to mark each uneven point, so it is necessary to design a test instrument that can measure and mark the flatness of high-precision metal plates. Contents of the invention

[0003] The object of the present invention is to provide a flatness tester for high-precis...
