A measuring tool for engine piston connecting rod

Abstract

The invention discloses a measuring tool for an engine piston connecting rod, which comprises an adjusting mandrel extending along the horizontal direction, one end of which is fixedly connected to a workbench, and the other end is slidingly connected with an adjusting slider. An adjustment platform for adjusting the height in the vertical direction. The adjustment disc is connected to the workbench through the rotating part. One end of the transmission rocker arm is hinged to the adjustment disc, and the other end is hinged to the guide rocker arm, which is fixed to the workbench. The guide platen is provided with at least two slide grooves opened along its radial direction, and the adjusting disc rotates and each clamping column provided on the guide rocker slides in the respective corresponding slide grooves, and the piston The end surface of the large hole of the connecting rod is in contact with the guide plate, and the inner wall of the large hole is in contact with each of the clamping columns, and the end surface of the small hole of the piston connecting rod is in contact with the adjustment platform. By adopting this technical solution, the matching precision is reduced, the processing difficulty is reduced, and the common use of the measuring tool for piston connecting rods of different models 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
