Abstract

The invention discloses an automatic clamping mechanism of a valve stem of a fire hydrant. The automatic clamping mechanism has the advantages that the valve stem of the fire hydrant can be automatically clamped by the aid of a cam mechanism and a lever mechanism and can be linked with a feeding mechanism, so that machining automation can be implemented, labor can be saved, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to an automatic clamping mechanism for a valve rod of a fire hydrant. Background technique [0002] During the processing of the traditional fire hydrant valve stem, manual control and clamping are required, and manual operation is required for each processing. The processing efficiency is low, manpower is wasted, and labor costs are increased. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic clamping mechanism for a fire hydrant valve stem that can automatically complete clamping or loosening. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: an automatic clamping mechanism for a fire hydrant valve rod, including a workbench, a spindle box is provided on the workbench, and a freely rotatable The main shaft...
