Beam-type supporting frame aperture multi-geometric tolerance detection device

Abstract

The present invention discloses a beam-type supporting frame aperture multi-geometric tolerance detection device. The device comprises a handle and two checking sticks, a big cover plate is arranged at the lower portion of the handle, and the front side plate and the back side plate are parallel to each other and are both in vertical connection with the bottom surface of the big cover plate; and the front side plate and the back side plate are L-shaped plate structure, free ends are respectively provided with a front side plate through hole and a back side plate through hole, and the one sides of the free ends of the front side plate and the back side plate are respectively provided with linings. The beam-type supporting frame aperture multi-geometric tolerance detection device can be configured for checking of the beam-type supporting frame aperture multi-geometric tolerance, is simple in structure, convenient to carry, easy to operate, effective in checking and not high in the checkers' skill requirement, can enforce the checking prior to entering an assembly line so as to solve the quality control problem of products in batch on the assembly line, save the detection time and improve the detection efficiency.

Description

technical field [0001] The invention belongs to a tolerance detection device, in particular to a multi-shape tolerance detection device for the aperture of a beam-type support frame. Background technique [0002] In the mechanical field, the beam support frame is a very common support structure, which plays a role in supporting and positioning the core components. Therefore, multiple positioning holes with different diameters will be processed on the same support frame. Whether the relative positional relationship such as coaxiality and position meet the requirements directly affects the performance of the support frame. It is a number of key geometrical tolerances to ensure that the core components are correctly assembled and do not interfere with each other. If there is a deviation in the key geometrical tolerances , It will cause the core working parts to fail to work normally, or even fail to assemble normally. It is usually necessary to check the shape and position tol...

AI Technical Summary

Problems solved by technology

For the detection of the coaxiality and position of holes, predecessors have designed many efficient and convenient inspection devices that can realize a certain form and position tolerance alone, but for the coaxiality and position of positioning holes with different diameters at the same time However, there is little research and design of related inspection devices.
