Boundary dimension testing tool for crawler support

Abstract

The present invention provides a boundary dimension testing tool for crawler support. The boundary dimension testing tool comprises a bottom plate, a plurality of supporting plates arranged in parallel are fixedly installed in the middle of the top surface of the bottom plate, and a testing box body is fixedly buckled on the edge of the top surface of the bottom plate; a plurality of adjusting insertion holes which are formed at intervals are formed in the top surface of the supporting plate, and positioning rods which extend upwards are inserted and fixed in the adjusting insertion holes; the top plate and the side plates of the inspection box body are provided with inspection jacks, the top plate of the inspection box body is connected with a positioning rod in a penetrating manner, and two opposite side walls of the inspection box body are movably connected with partition plates for shielding the inspection jacks in a hanging manner. The testing tool does not need to measure the length and width of each plane of the crawler belt support, and effectively improves the inspection efficiency on the basis of avoiding measurement errors.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a tool for inspecting the outer dimensions of a crawler bracket. Background technique [0002] After the welding process of the crawler bracket in the prior art is completed, the length and width dimensions of each plane need to be checked. The calibration in the prior art is usually measured manually using a vernier caliper or a tape measure, but because the size of the track bracket is often large , which is greater than the maximum range of conventional vernier calipers, and the measurement with a tape measure cannot be accurate to the millimeter level, resulting in a large error. [0003] Therefore, how to design a special external dimension inspection tool for track brackets, which can quickly measure the length and width values ​​of the plane without using vernier calipers, is a problem to be solved urgently by those skilled in the art. Contents of the invention [0004...
