Spindle mechanism with telescoping and rotating functions

Abstract

The invention particularly relates to a main shaft mechanism with extending and contracting as well as rotating functions, which is applied to a hardware electroplating blunting line of automobile parts in an electroplating industry, and discloses the main shaft mechanism with the extending and contracting as well as rotating functions. The main shaft mechanism with the extending and contracting as well as rotating functions comprises an air cylinder and a bearing pedestal, wherein the output end of the air cylinder is connected with a connection rotation joint; the connection rotation joint comprises a shell; a bearing is arranged in the shell; a rotary hollow shaft is rotated under the driving of a driving gear and a driven gear, so that the main shaft is driven to rotate through a shaft key and the bearing. The main shaft mechanism has the benefits as follows: independent extending and contracting of the main shaft are realized, and in addition, the rotation of the main shaft is also realized on the premise of driving without rotation, so that combined action of rotation, extending and contracting of a mechanism mounted at the shaft end are realized, the action of the equipment is diverse and the main shaft mechanism is suitable for production of various products.

Description

technical field [0001] The invention is applied to the metal electroplating passivation line of auto parts in the electroplating industry, and in particular relates to a main shaft mechanism with telescopic and rotating functions. Background technique [0002] In the metal plating passivation line of auto parts in the electroplating industry, the spindle mechanism is used on the assembly line to realize the expansion and rotation of the spindle through driving, so as to drive the mechanism installed on the shaft end to realize a series of processes in the passivation production line. However, the current main shaft mechanism has defects: a main shaft mechanism can only realize the independent expansion and contraction of the main shaft, or realize the main shaft rotation under the premise that the drive does not rotate, so that the mechanism installed at the end of the shaft can only realize it alone The rotation or in-and-out action cannot realize the combined action of rot...
