Automatic-jacking tailstock capable of rapidly moving

Abstract

The invention discloses an automatic-jacking tailstock capable of rapidly moving, which has the advantages that the use is convenient and the working efficiency is greatly improved. The automatic-jacking tailstock comprise a bottom plate, wherein a linear slide rail is fixedly connected to the bottom plate; a moving cylinder is fixedly connected to one end of the bottom plate and is provided with a moving cylinder piston rod; the central line of the moving cylinder piston rod is parallel to the walking direction of the linear slide rail; a tailstock backing plate is fixedly connected to the free end of the moving cylinder piston rod; a slide block is fixedly connected below the tailstock backing plate; the slide block is connected with the linear slide rail in a sliding manner; a tailstock body is fixedly connected to the tailstock backing plate; the tailstock body is hollow; a tailstock sleeve is connected in the tailstock body in a sliding manner; a jacking cylinder is fixedly connected to the rear end of the tailstock body and is provided with a jacking cylinder piston rod; the free end of the jacking cylinder piston rod is fixedly connected with the rear end of the tailstock sleeve; a tip is sleeved at the front end of the tailstock sleeve; and the contact surface of the tip and the tailstock sleeve is conical. The free end of the moving cylinder piston rod is connected with the tailstock backing plate via a connecting block.

Description

technical field [0001] The invention relates to an automatic tightening tailstock structure, in particular to a fast-moving automatic tightening tailstock. Background technique [0002] Pneumatic tailstock tightening is one of the devices often used in machining. The existing automatic tailstock tightening is a structure in which the tailstock body moves axially along the tailstock sleeve or tightens axially. When processing thin and thin-walled pipe fittings clamped on the mandrel, the tailstock needs to move a long distance to replace the workpiece, and the tailstock also takes up a lot of space, and the operation of the upper and lower parts is inconvenient, and the long-distance movement of the tailstock is wasteful. It takes time and affects the processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a fast-moving automatic tightening tailstock which is easy to use and greatly improves work efficiency. [0004] To ...
