Engine piston rod measuring tool

Abstract

The present invention discloses an engine piston rod measuring tool. The engine piston rod measuring tool comprises an adjusting core shaft extending along a horizontal direction, one end of the adjusting core shaft is fixedly connected with a workbench while the other end is connected in a sliding manner with an adjusting sliding block, the adjusting sliding block is provided with an adjusting stage for height adjustment in a vertical direction, an adjusting disc is connected in a rotating manner onto the workbench through a rotating part, one end of a driving swing arm is hinged to the adjusting disc while the other end is hinged to a guide swing arm, a guide press plate fixedly connected onto the workbench is provided with at least two sliding chutes along a radial direction of the guide press plate, the adjusting disc rotates and drives clamping posts disposed on the guide swing arm to be connected in a sliding manner into the respective sliding chutes, the end face of a large hole of a piston rod is attached to the guide press plate, the inner wall of the large hole is abutted against the clamping posts, and the end face of a small hole of the piston rod is attached to the adjusting stage. With adoption of the technical scheme, the coordinating precision is reduced, the processing difficulty is lowered, and universality of the measuring tool to piston rods of different types is realized.

Description

technical field [0001] The invention belongs to the field of detection tools, and in particular relates to a measuring tool for an engine piston connecting rod. Background technique [0002] Before measuring the distance between the large and small holes of the engine piston connecting rod, and the diameter of the large and small holes, it is necessary to place the piston connecting rod horizontally and measure the plane of the end faces of the large and small holes of the piston connecting rod To ensure the accuracy of subsequent measurement data. [0003] Existing measuring tools such as figure 1 As shown, the workbench 1' is provided with a first mating end 11' and a second mating end 12', the large hole of the piston connecting rod fits outside the first mating end 11' and fits with the workbench 1, and the second mating end A gasket 13' is arranged on the end 12', and the height of the gasket 13' is the height difference between the end surface of the large hole of th...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned measuring tool has the following defects: the measuring tool can only be used for one type of piston connecting rod, and its versatility is poor; and when the first mating end 11' is positioned with the large hole of the piston connecting rod, the accuracy requirements High, resulting in difficult processing of measuring tooling
