Abstract

The invention discloses an electric central frame for a crankshaft. The electric central frame comprises a base, wherein a transmission shaft I, a transmission shaft II and a transmission shaft III are arranged on the base; driven rack sleeves are fixedly connected on the transmission shaft I and the transmission shaft II; driven rack parts are arranged on the driven rack sleeves; a motor is arranged at one end of the transmission shaft III; a drive rack sleeve is arranged at the other end of the transmission shaft III; a thread transmission part is arranged on the transmission shaft III; a thread transmission hole is formed in the drive rack sleeve; the thread transmission part is arranged in the thread transmission hole; a pair of drive rack parts are symmetrically arranged on the drive rack sleeve; and gear transmission pairs are arranged between the drive rack parts and the driven rack parts. According to the electric central frame for the crankshaft, the drive rack parts transmit power to the driven rack sleeves through the gear transmission pairs, so that large and small shaft heads of the crankshaft are clamped and released through three locating bearings, the locating speed is high, and the locating accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical cutting tooling, and in particular relates to a crankshaft electric steady frame. Background technique [0002] The crankshaft is the main rotating part of the engine. After the connecting rod is installed, the reciprocating motion of the connecting rod can be transformed into a circular rotating motion. It is an important and precise part of the engine. In the process of machining the big and small shaft heads and the main shaft hole of the crankshaft on the lathe, it is necessary to support and center the two ends of the crankshaft. The current lathe fixture has the following problems: the lathe fixture is a pure manual fixture, and there are many operation steps, which is time-consuming and laborious; The center positioning performance of the lathe fixture is poor, and it is difficult to meet the high-precision machining requirements of the crankshaft. Contents of the invention [0003] A...
