Abstract
The utility model relates to an expansion type axial positioner, and belongs to the field of machining tools. The positioner comprises a threaded shaft and a positioning rod inserted in one end of the threaded shaft in a penetrating mode, wherein the positioning rod and the threaded shaft are fixed through a nut A, the outer circumference of the threaded shaft is sleeved with a conical shaft, the outer circumference of the conical shaft is sleeved with an expansion sleeve, an adjusting nut B for adjusting and fixing the expansion sleeve is arranged on the outer circumference of the conical shaft, and a nut C for adjusting and fixing the conical shaft and the threaded shaft is arranged on the outer circumference of the threaded shaft. According to the expansion type axial positioner, the positioning rod is connected with the threaded shaft through threads, the length of the positioning rod is determined according to the requirement for finishing size, the positioning rod is fixed in an expansion mode through the expansion sleeve, a spring chuck of a numerical control lathe is positioned and clamped fast, conveniently and accurately, axial positioning of a workpiece is achieved, and the axial positioning accuracy of the workpiece in the machining process is guaranteed. Besides, only the situation that the workpiece is tightly clamped by the workpiece needs to be taken into consideration, the positioning problem does not need to be taken into consideration, and therefore universality of tools is increased, the types and the number of auxiliary tools are reduced, and fewer auxiliary tools need to be manufactured.
Description
Technical field
The utility model relates to a kind of expansion type axial location device, belongs to machining apparatus field.
Background technology
On numerically controlled lathe, use at present collet clamping workpiece, in 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 existing 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 general expansion type axial location device 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 expansion type axial location device, 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 to arrange on the adjusting nut B, thread spindle excircle of fixed expansion sleeve 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 65Mn steel is made.
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. expansion type axial location device 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 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. expansion type axial location device 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 workman being processed to experience.
3. the expansion type axial location device 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model expansion sleeve front view;
Fig. 3 is the utility model expansion sleeve left view;
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 utility model is further described:
As Figure 1-3: the utility model provides a kind of expansion type axial location device, comprise thread spindle 3, intert backstay 1 in thread spindle 3 one end, backstay 1 and be fixed by nut A2 with thread spindle 3, 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 to arrange on the adjusting nut B6, thread spindle 3 excircles of fixed expansion sleeve 5 adjusts the fixedly nut C7 of the axis of cone 4 and thread spindle 3.Backstay adopts and is threaded with thread spindle, according to the requirement of 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 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 is made for 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.
