Problems solved by technology

[0002] Traditional lathes for processing the outer circumference of shaft parts use a screw to drive the spindle to feed. The stroke control of the screw is slow, and the screw is easily damaged. The return of the spindle needs to switch gears or reverse the motor, and the operation is complicated.

Abstract

The invention discloses a fire hydrant valve rod outer circumference machining device. A main shaft box (2) is driven through a cam mechanism and a lever mechanism to slide back and forth on a workbench (1) to achieve a self-return function and improve the automation degree, and automatic feeding, reloading and machining without manual operation can be achieved by further combining an automatic feeding device. The intensity of the cam mechanism and the intensity of the lever mechanism are higher than that of a screw rod, and the service life is long.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a processing device for the outer circumference of a valve stem of a fire hydrant. Background technique [0002] Traditional lathes for processing the outer circumference of shaft parts use a screw to drive the spindle to feed. The stroke control of the screw is slow, and the screw is easily damaged. The return of the spindle needs to switch gears or reverse the motor, which is complicated to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing device for the outer circumference of the valve stem of a fire hydrant, which has an automatic return function, a long service life and a high degree of automation. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a device for processing the outer circumference of a fi...
