A Universal Horizontal Workbench for Measuring Engine Piston and Connecting Rod

Abstract

The invention relates to a horizontal workbench for measuring universal type engine piston connecting rods. The horizontal workbench comprises a workbench body, an adjusting mandrel, an adjusting bolt, a helix adjusting gear, a guide pressing plate, guide blocks, a sleeve for fixation, a horizontal thread adjusting sliding block, a height adjusting table and a magnetic gasket. The split type adjustable design for fixing a big piston connecting rod end and fixing a small piston connecting rod end can be applied to piston connecting rods of different models, and universality is high; materials are selected more flexibly due to the split type design, the fixed mode of one-to-one use is avoided due to the adjustable design, and the situation that repeated labor is used for repeatedly measuring corresponding sizes of piston connecting rods in the manufacturing process and consequently machining precision of corresponding parts is greatly reduced is avoided.

Description

technical field [0001] The invention belongs to the field of detection tools, and in particular refers to a general-purpose horizontal workbench for measuring engine piston connecting rods. Background technique [0002] In order to ensure the distance between the large and small holes of the engine piston connecting rod and the measurement accuracy of the diameter of the large and small holes, it is necessary to place the piston connecting rod horizontally and ensure that the large and small ends of the piston connecting rod are at the same horizontal position. The traditional measurement method is to measure the diameter of the large end of the piston connecting rod, and accurately measure the height difference between the large and small end sections of the piston connecting rod, and make special tooling accessories for the measurement work, but the production cost of special tooling accessories is high, and the processing It is very difficult, and affected by the horizont...

AI Technical Summary

Problems solved by technology

[0005] 1. A tooling aid for measuring the piston and connecting rod of an engine can only be used for the piston and connecting rod of one model, which has poor versatility;

[0006] 2. The processing precision is high, the processing is difficult, and the processing cost is high;

[0007] 3. With the improvement of the engine pedigree and the increasing number of engine models, the number of special tooling and auxiliary tools required for measuring the piston and connecting rod of the engine is also increasing, which is not convenient for on-site management, and may easily cause circulation confusion and other phenomena;

[0008] 4. With the handover of the engine production task, the piston two-rod measuring tooling and auxiliary equipment dedicated to the original engine model faced the problem of scrapping, resulting in a lot of waste;

[0009] 5. With the release of tasks for new models, the machining unit needs to re-map the pistons and connecting rods of the new models, and design and produce special measuring tooling and accessories for engine pistons and connecting rods. Work intensity, wasting a lot of man-hours and resources;

[0010] 6 Special tooling and auxiliary tools for measuring engine pistons and connecting rods have high requirements for the horizontal accuracy of the measuring workbench and harsh requirements for the measuring site environment, with poor applicability
