Description

Stability-enhanced vertical lathe

Technical Field

The utility model relates to a vertical lathe field, concretely relates to be a vertical lathe of reinforcing stability.

Background

In the machining industry, the machine tool can be classified into a vertical type and a horizontal type according to the spindle feeding mode of the machine tool, and a vertical lathe machine tool is a common machine tool in workpiece machining and can grind an end face and drill holes as the name suggests.

As is well known, the existing lathe-erecting machine tool generally comprises a base with a workbench, a supporting seat erected on the base, a slide seat movably mounted on the supporting seat and capable of moving up and down, a y-axis driving device driving the slide seat to move up and down is mounted on the supporting seat, two slide rails arranged side by side up and down are fixedly mounted on the slide seat, a spindle box slide plate is mounted on the slide seat through the slide rails, and an x-axis driving device for driving the spindle box slide plate to move left and right is fixedly mounted on the slide seat. And a machining device for drilling or turning the end surface is arranged on the spindle box sliding plate (the machining device is a common machining machine head and comprises a spindle motor and a drill gun). In the process of processing holes by the vertical lathe, a workpiece is placed on the workbench along the horizontal plane, and a drill gun of the processing device is fed along the vertical direction and simultaneously rotates around the feeding direction, so that the holes can be processed at the preset position of the surface of the workpiece.

However, in the process of machining a hole, because the spindle head slide plate is only mounted on the slide seat by means of two slide rails which are arranged side by side up and down, and the machining device is fixedly mounted on the spindle head slide plate to form a suspension mode, the spindle head slide plate is stressed greatly, and the following two disadvantages are generated: firstly, the brill rifle receives the work piece and produces a vertical reaction force that makes progress in drilling processing, transmits for the headstock slide through the brill rifle for the anti stability of headstock slide is not enough easily produces the drunkenness from top to bottom. Secondly, the slide plate of the spindle box is easy to be unstable, and the processing precision is reduced. And thirdly, the service life of other transmission parts on the existing vertical lathe is influenced due to the influence of other transmission parts.
