An automatic indexing device for an engine crankshaft pulley

Abstract

The invention discloses an automatic indexing device of an engine crankshaft belt wheel. The automatic indexing device comprises a base and an indexing table located on the base. The indexing table comprises a speed reduction servo motor, a transmission shaft, a supporting mechanism and a clamp jaw device. The transmission shaft is mounted on the supporting mechanism. The speed reduction servo motor and the clamp jaw device are mounted at the two ends of the transmission shaft correspondingly. Four clamp jaw pins used for abutting against a crankshaft belt wheel spoke at the same time are arranged on the clamp jaw device. A manual rotary disc used for driving the transmission shaft to rotate is further arranged on the transmission shaft. According to the automatic indexing device, the clamp jaw device is driven by the speed reduction servo motor, the four clamp jaw pins on the clamp jaw device drive the belt wheel spoke to rotate, and manual operation is completely replaced; and by means of the arranged speed reduction servo motor, heavy labor brought by manual operation is solved, the accuracy and production efficiency of corners of flywheel discs are improved, and meanwhile the assembly quality is improved.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to an automatic indexing device for an engine crankshaft pulley. Background technique [0002] With the rapid development of the automobile industry, higher requirements are put forward for its assembly automation level. In the automobile engine assembly process, the bolt tightening of the flywheel disc at the end of the crankshaft is an important process. As we all know, there are six bolts evenly distributed along its circumferential direction on the flywheel disc. When assembling, the process requires that the flywheel disc should be rotated by 60° every time a bolt is tightened, and then continue to tighten the next one. In the prior art The best way is to manually hold the corresponding fixture and directly rotate the flywheel. This operation has the following disadvantages: [0003] 1. It is time-consuming and labor-intensive, which not only increases the labor intensity of wo...

AI Technical Summary

Problems solved by technology

[0003] 1. It is time-consuming and labor-intensive, which not only increases the labor intensity of workers, but also cannot fully guarantee the production pace;

[0004] 2. The strength of manual rotation of the flywheel is uncertain, which will directly affect the accuracy of the rotation angle, which is not conducive to the improvement of product assembly quality
