Abstract

The invention discloses a vertical symmetry inspection tool for a piston pin hole, which comprises a bottom plate and a first connecting plate, one end of the bottom plate is vertically connected with one end of the first connecting plate, and the other end of the first connecting plate is vertically connected with the second connecting plate. Two connecting plates, the verticality symmetry of the piston pin hole has a simple structure. By adding the first dial indicator and the second dial indicator, the first dial indicator can position one end of the detection mandrel, and then insert the test mandrel into the To the side of the piston pin hole, place the detection mandrel in the V-shaped block, rotate the test mandrel, and then read the first dial gauge, and at the same time, the second dial gauge can measure the radial runout Then use the test mandrel to insert the other side of the piston pin hole to measure another set of readings. The combination of the first dial indicator and the second dial indicator greatly improves the measurement accuracy, is convenient to operate, does not need to consume too much manpower, and directly uses the frame to adjust and fix the measurement.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to a inspection tool for verticality symmetry of piston pin holes. Background technique [0002] In the mechanical industry, the vertical symmetry of the piston pin hole to all axes directly affects the performance of the piston when it is working. At present, most piston manufacturers use a hand-held vertical symmetry tester for the piston pin hole. The principle is to insert the mandrel into one side of the piston pin hole, use the outer end of the circle to locate, and use a dial gauge or a dial gauge to measure the side of the pin hole. Take a reading at one end, and then insert the mandrel into the other side of the piston pin hole to measure another set of readings. The difference between the two sides of the pin holes on both sides is the numerical value of the vertical symmetry of the piston. However, at present, most of the internal combustion engine pistons use ...
