Abstract

The invention relates to a positioner, which belongs to the field of machining tools. The positioner comprises a threaded shaft and a positioning rod, wherein the positioning rod is inserted into one end of the threaded shaft; the positioning rod and the threaded shaft are fixed through a nut A; a conical shaft is sleeved on the outer periphery of the threaded shaft; an expansion sleeve is sleeved on the outer periphery of the conical shaft; the outer periphery of the conical shaft is provided with an adjusting nut B for adjusting and fixing the expansion sleeve; the outer periphery of the threaded shaft is provided with a nut C for adjusting and fixing the conical shaft and the threaded shaft. According to the positioner, the positioning rod is in threaded connection with the threaded shaft, the length of the positioning rod is determined according to the requirement of machining size, and the expansion sleeve expands for fixing, so that positioning and clamping of a spring clamp of a numerical control lathe are finished rapidly, conveniently and accurately, axial positioning of workpieces is realized, and the axial positioning accuracy of workpieces in a machining process is ensured. Moreover, only a workpiece clamping tool needs to be considered, and the problem of positioning does not need to be considered, so that the universality of the tool is enhanced, and the variety, quantity and manufacturing of an auxiliary tool are reduced.

Description

A kind of locator
Technical field
The present invention relates to a kind of locator, belong to machining apparatus field.
Background technology
Use at present the collet clamping workpiece on numerically controlled lathe, on the axial location of workpiece, generally adopt auxiliary mould fixedly to realize axial location by border.This method has the following disadvantages:
1. when processing parts axial location change in size, frock need to be again made, processing request could be met, the making of a large amount of frocks, a large amount of human and material resources and the financial resources of meeting loss, and also its production cycle is long.
2. in process, the precision that this kind adopts auxiliary mould to carry out axial location does not often reach the processing request of part, and the making of auxiliary mould is higher to skilled worker's operational capacity and processing experience dependence.
Summary of the invention
In order to overcome the defect existed in prior art, the present invention aims to provide and a kind ofly by adjusting can fast, accurately, both save time also labour-saving of expansion sleeve and backstay length, completes the universal locator of the positioning and clamping of numerically controlled lathe collet.
To achieve these goals, the present invention is by the following technical solutions:
A kind of locator, the backstay, backstay and the thread spindle that comprise thread spindle, intert in thread spindle one end are fixed by nut A, and thread spindle excircle cover has the axis of cone, axis of cone excircle cover to have expansion sleeve, axis of cone excircle to be provided with to adjust on the adjusting nut B, thread spindle excircle of fixed expansion sleeve to arrange adjusts the fixedly nut C of the axis of cone and thread spindle.
Described expansion sleeve is that metal material is made.
Described expansion sleeve is that the 65Mn steel forms.
Described expansion sleeve line cutting is provided with at least two elastic opening grooves.
The described axis of cone, expansion sleeve are made through modifier treatment.
The conical surface of the described axis of cone and expansion sleeve is processed through fine grinding.
Compared with prior art, the present invention has the following advantages:
1. the locator backstay adopts and is threaded with thread spindle, according to positional parameter, determines backstay length, then is locked with nut, has just realized the axial location of workpiece.Therefore only need to consider the Workpiece clamping frock, and no longer consider orientation problem, this has increased the versatility of frock, has reduced the making of kind, quantity and the frock of auxiliary mould, has saved a large amount of human and material resources and financial resources.
2. locator is threaded connection, and nut is fixed, and expansion sleeve expand fixing structure and principle, be easily understood, and facilitates workman's left-hand seat, alleviated the dependence of the workman being processed to experience.
3. the locator axis of cone and expansion sleeve are through modifier treatment, durable in use, and the conical surface of the axis of cone and expansion sleeve is processed through fine grinding, and quality of fit is high.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is expansion sleeve front view of the present invention;
Fig. 3 is expansion sleeve left view of the present invention;
In figure: backstay 1, nut A2, thread spindle 3, the axis of cone 4, expansion sleeve 5, nut B6, nut C7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
As Figure 1-3: the invention provides a kind of locator, comprise thread spindle 3, intert backstay 1 in thread spindle 3 one ends, backstay 1 and be fixed by nut A2 with thread spindle 3, arrange on the adjusting nut B6 that thread spindle 3 excircle covers have the axis of cone 4, axis of cone excircle cover to have expansion sleeve 5, the axis of cone 4 excircles to be provided with to adjust fixed expansion sleeve 5, thread spindle 3 excircles and adjust the fixedly nut C7 of the axis of cone 4 and thread spindle 3.Backstay adopts and is threaded with thread spindle, requirement according to processing dimension, determine backstay length, utilize expansion sleeve to expand fixing, complete conveniently, accurately fast, the positioning and clamping of numerically controlled lathe collet, realize the axial location of workpiece, guaranteed the axial location precision of workpiece in process.And only need consider the Workpiece clamping frock, and no longer consider orientation problem, this has increased the versatility of frock, has reduced the making of kind, quantity and the frock of auxiliary mould.
Described expansion sleeve 5 is made for metal material.
Further, in order to improve its wearability, described expansion sleeve 5 forms for the 65Mn steel.
Described expansion sleeve 5 line cuttings are provided with at least two elastic opening grooves.
The described axis of cone 4, expansion sleeve 5 are made through modifier treatment, durable in use.
The conical surface of the described axis of cone 4 and expansion sleeve 5 is processed through fine grinding, and its quality of fit is high.
