Description

Tailstock device for vertical lathe

technical field

The utility model relates to a machine tool accessory, in particular to a tailstock device for a vertical lathe.

Background technique

When using a machine tool to process a workpiece, the top plate on the tailstock is usually used to fix the workpiece on the rotary device, and then the tool is used to process the workpiece. The current tailstock usually uses a motor to drive it to move along the guide rail, the position adjustment efficiency is slow, which affects the processing efficiency, and the fixing effect on the workpiece is not good.

Contents of the invention

In order to overcome the above-mentioned technical problems, the utility model provides a tailstock device for a vertical lathe with reasonable structural design, good fixing effect, convenient position adjustment and improvement of processing efficiency.

In order to achieve the above technical purpose, the utility model adopts the following scheme: a tailstock device for a vertical lathe, including a tailstock bracket and a slider that can move up and down along the tailstock bracket, and is characterized in that: the slider is made of Driven by motor and lead screw mechanism, a sleeve is fixed on the front side of the slider. A telescopic cylinder that moves the axis of rotation up and down.

The utility model has the following beneficial effects: the slider is driven by a motor through a screw mechanism, and the large-scale movement of the workpiece pressing plate can be adjusted; the telescopic cylinder can adjust the small-range movement of the workpiece pressing plate position, and can Controls the pressure exerted on the workpiece. The structure is simple, the control is convenient, and it is beneficial to improve the processing efficiency.
