Abstract

A rotary indexing device is used for indexing and rotating a workbench during multi-station processing and is composed of the workbench, an upper toothed disk, a lower toothed disk, a frame, a lifting/descending oil cylinder, a gear, a rack oil cylinder and a drive pin disk, wherein during working, oil is fed by a lower chamber of the lifting/descending oil cylinder and returned by an upper chamber; the workbench and the drive pin disk move up and the upper toothed disk and the lower toothed disk are disconnected; a drive pin is inserted into a drive pin hole formed on the end surface of the gear, oil is fed by the lower chamber of the lifting/descending oil cylinder and returned by the upper chamber and the rack moves forward to drive the gear to realize the rotary indexing of the workbench; at the arrival of a specified indexing angle, oil is fed by the lower chamber of the lifting/descending oil cylinder and returned by the upper chamber, and the workbench and the drive pin disk move downward; the upper toothed disk and the lower toothed disk are engaged and positioned, thus the indexing precision is guaranteed; the drive pin is pulled out of the drive pin hole on the end surface of the gear, then oil is fed by a rear chamber of the rack oil cylinder and returned by a front cylinder; the rack falls back to an original position and then stops, at this moment, the gear rotates clockwise on idle around a lifting piston rod and makes preparation for next rotary indexing.

Description

technical field [0001] The invention relates to a rotary indexing device for multi-station processing, in particular to a rotary indexing device driven by a rack oil cylinder. Background technique [0002] The rotary indexing device is an important equipment in machinery manufacturing, hardware, light industry and other industries. It is developed on the basis of the working principle of the rotary table for boring and milling processing. Compared with the rotary table for boring and milling processing, the rotary indexing device is in There is no processing during the rotation process, as long as the indexing accuracy is guaranteed. Commonly used numerical control indexing devices have a high degree of automation and accurate indexing, but they need to be controlled by a numerical control device and are expensive. For applications that require general indexing accuracy, the development of a new type of rotary indexing device with simple structure, low cost and reliable oper...
