Abstract

The utility model discloses a workpiece alignment tool for a lathe. The workpiece alignment tool comprises a main body, a guide bolt, a rolling bearing, a gasket and a nut, wherein a through hole is formed in the front end of the main body, and the rolling bearing is mounted on the left side of the main body; the guide bolt penetrates through an inner hole of the rolling bearing and the through hole of the front end of the body; the guide bolt is arranged on the right side of the main body and sequentially sleeved with the gasket and the nut into a whole. During operation, the workpiece alignment tool is mounted on a square tool post of the lathe; when a workpiece rotates, the rolling bearing is in contact with the outer circle or end face of the workpiece to guarantee that the workpiece is mounted at a correct position. The workpiece alignment tool, disclosed by the utility model, has the characteristics of simple structure, convenience for use and reliability in operation and capability of achieving the radial or axial alignment of the workpiece.

Description

A kind of lathe workpiece alignment tool

Technical field

The utility model relates to workpiece accessory, more precisely a kind of lathe workpiece alignment tool is installed.

Background technology

On lathe, during turner, workpiece centering is the basic operation method that guarantees machining accuracy.The method of conventional workpiece centering is to utilize dial gauge to play table to measure offset or dish, recycles copper or rubber hammer and knocks.This method of operating, needs repeatedly centering and knocks guarantee and install correctly, and operating process is loaded down with trivial details, and efficiency is low.

Utility model content

The utility model is in order to make up above-mentioned deficiency, provides a kind of being used on lathe, workpiece to be carried out radially or the instrument of axial spotting.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of lathe workpiece alignment tool, comprise body, guide blot, rolling bearing, packing ring and nut, at described body front end, there is a through hole, in the left side of body, described rolling bearing is installed, described guide blot is through rolling bearing endoporus and body front end through hole, on body right side, be inserted in successively packing ring and nut, make it to become an integral body.

As the utility model preferred embodiment, described body section is rectangle, and its upper and lower two planes are clamping face.

As the utility model preferred embodiment, described guide blot is comprised of stopper, optical axis part and threaded portion.

The utility model is when work, and workpiece centering instrument is arranged on the square tool post of lathe, during workpiece rotation, utilizes cylindrical or end contact between rolling bearing and workpiece, and guarantees that workpiece obtains correct installation site.

The utility model has the advantages that, simple in structure, can realize workpiece radially or axial centering, easy to use, reliable operation.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

The utility model provides a kind of lathe workpiece alignment tool.

As shown in Figure 1, a kind of lathe workpiece alignment tool, comprise body 3, guide blot 1, rolling bearing 2, packing ring 4 and nut 5, at described body front end, there is a through hole 6, described rolling bearing 2 is installed in the left side of body, described guide blot 1, through rolling bearing endoporus 8 and body front end through hole 6, is inserted in packing ring 4 and nut 5 successively on body right side, make it to become an integral body.

As shown in Figure 2, described body 3 cross sections are rectangle, and its upper and lower two planes are clamping face.

As shown in Figure 3, described guide blot 1 is comprised of stopper 9, optical axis part 10 and threaded portion 11.

Be illustrated in figure 4 and on lathe, utilize the utility model to carry out the radially schematic diagram of centering of workpiece.

Be illustrated in figure 5 the schematic diagram that utilizes the utility model to carry out workpiece axial spotting on lathe.

Below only with an embodiment, mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to external more functional module simultaneously, thereby expands to greatest extent its function.

The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
