Abstract

The invention discloses a crankshaft key groove length gauge, comprising a key groove detection block, wherein a key groove tail measuring block and a key groove head measuring block are arranged on the key groove detection block, a key groove tail measuring port is formed in the bottom of the key groove tail measuring block, a key groove head measuring port is formed on the left side of the key groove head measuring block, and the key groove detection block is provided with chamfers. The crankshaft key groove length gauge is scientific and reasonable in structure and convenient to use; through the measuring ports in the key groove measuring blocks, whether a crankshaft key groove is qualified or not can be conveniently detected, and the crankshaft key groove detection efficiency is improved; through scales on the key groove measuring blocks, the crankshaft key groove detection precision is improved, and the crankshaft key groove can be conveniently detected; moreover, the crankshaft key groove block is integrated, so that damage of a measuring gauge is avoided and the practicability of the measuring gauge is improved.

Description

technical field [0001] The invention relates to the technical field of measuring and checking tools, in particular to a checking tool for the length of a crankshaft keyway. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy. The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. The keyway is a groove matched with the key machined on the shaft or in the hole, which is used to install the key to transmit torque. [0003] In the process of machining the crankshaft keyway, it is necessary to measure and i...
