M1C main shaft length testing fixture

Abstract

The invention discloses an M1C main shaft length testing fixture. The M1C main shaft length testing fixture comprises a dial indicator alignment part seat, a dial indicator alignment part, a V-shaped seat, a dial gauge positioning seat, a copper sleeve, a dial gauge, a first socket cap screw and a second socket cap screw, wherein the upper surface of the V-shaped seat is provided with the dial indicator alignment part, the dial indicator alignment part seat is fixed at the left side of the dial indicator alignment part through the first socket cap screw, the dial gauge positioning seat is fixed at the right side of the V-shaped seat through the second socket cap screw, the dial gauge positioning seat is internally provided with the copper sleeve, and the dial gauge is installed in the copper sleeve. The M1C main shaft length testing fixture is scientific and reasonable in structure and safe and convenient to use, a special-purpose length testing fixture cooperates with the dial gauge for application, length readings can be directly read, the testing fixture is more convenient, rapid and efficient during application and measurement, the overall volume is quite small, the carrying is convenient, and large-scope promotion and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of spindle length detection, in particular to an M1C spindle length detection tool. Background technique [0002] The crankshaft is the main rotating part of the engine. After the connecting rod is installed, it can undertake the up and down (reciprocating) motion of the connecting rod and turn it into a cyclic (rotating) motion. It mainly includes the main journal and the connecting rod journal. The main journal is installed on the cylinder block, the connecting rod journal is connected with the large end hole of the connecting rod, and the small end hole of the connecting rod is connected with the cylinder piston. It is a typical crank slider mechanism. The key technology of crankshaft heat treatment is surface strengthening treatment. [0003] In recent years, a batch of advanced forging equipment has been introduced in China, but due to the small quantity, mold manufacturing technology and other facilit...

Problems solved by technology

Generally speaking, there are many obsolete ordinary forging equipment that need to be transformed and updated. At the same time, backward technology and equipment still occupy a dominant position, and advanced technology has been applied but not yet universal.

[0004] It must be mentioned that the length of the main shaft is particularly important in the production process of the crankshaft and must be accurately grasped. However, today's measuring tools are not only extremely inconvenient to measure, but also have low measurement accuracy, which directly restricts my country's engine industry. The healthy development of
