Description

Lathe positioning tool

Technical Field

The utility model relates to the technical field of mechanical tools, in particular to a lathe positioning tool.

Background

The existing lathe positioning tool is used for boring a blind step structure on a jaw by using a boring cutter, and is used for clamping a workpiece, and steps corresponding to the length and the diameter of the workpiece need to be continuously bored on the jaw along with the change of the length and the diameter of the clamped workpiece, so that the strength of the jaw is easily reduced, and the jaw is deformed and scrapped.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a lathe positioning tool.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a lathe location frock which characterized in that: including chuck, jack catch and backup pad, the chuck center is hollow structure, the terminal surface is equipped with a plurality of draw-in grooves on the equidistance on the circumferencial direction before the chuck, draw-in groove and chuck centre bore intercommunication, the jack catch is pegged graft in the draw-in groove internalization, the backup pad is located the chuck front end, be equipped with the inserting groove who matches with the jack catch in the backup pad, the jack catch passes the inserting groove, backup pad central thread connects positioning bolt.

Further, the method comprises the following steps of; the jack catch side is equipped with the slide rail, the draw-in groove medial surface is equipped with the spout that matches with the slide rail, the slide rail can follow the spout and slide.

Further, the method comprises the following steps of; the supporting plate is integrally disc-shaped.

Further, the method comprises the following steps of; and a cushion block is arranged between the positioning bolt and the support plate.

The utility model has the beneficial effects that:

1) the utility model avoids boring a step structure on the jaw, and can prevent the jaw from being damaged;

2) the utility model can process workpieces with different diameters, and has strong universality and high utilization rate.

3) The height of the workpiece can be freely adjusted by adjusting the positioning bolt, and the operation is simple;

4) the chuck has the advantages of simple structure and low cost, and machining chips can be prevented from entering the chuck through the arrangement of the supporting plate.
