Description

A kind of low module axis tooth internal spline clamp for machining
Technical field
The utility model relates to Gear Processing field more particularly to a kind of low module axis tooth internal spline clamp for machining.
Background technique
Low module axis tooth internal spline is the important connection type in mechanical engagement, and requirement on machining accuracy is higher, therefore is added Work difficulty is also relatively high;There is the axial workpiece of low module axis tooth internal spline there are problems that location difficulty in processing, lead to It is positioned and is bothered with fixture, it is difficult to reach the machining accuracy of needs, it is therefore desirable to design a set of dedicated positioning fixture.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of low module axis tooth internal spline and add Clamping apparatus, energy consumption is small, high-efficient.
The utility model is achieved through the following technical solutions:
A kind of low module axis tooth internal spline clamp for machining has mould, and mould is connected by screw on platen, Mould is provided centrally with hole, and tapered set is connected by screw in hole, and coning sleeve bottom has been connected by screw to top, coning sleeve Be provided centrally with elastic collet, be provided on elastic collet with coning sleeve taper be adapted taper, and can be in coning sleeve on Lower slider, it is top on be provided with via hole, be provided with spacer in via hole, elastic collet passes through pull bar screw in spacer and top bottom The collet pull rod of portion's setting is coupled, and the collet pull rod other end is connect by T-nut with oil cylinder pull rod, and oil cylinder pull rod is driven by oil cylinder It is dynamic.
Preferably, the mould is in taper type.
Preferably, the taper angle of the coning sleeve is not more than 5 °.
Preferably, the elastic collet side is provided with vertical waist type groove, it is arranged on mould corresponding with waist type groove Pin hole, the spacer pin of the restricted elastic collet abjection of the interior setting of pin hole.
Preferably, the spacer and top via hole interference fit, it can be free to slide between pull bar screw and spacer.
The utility model relative to existing technologies, when solving the Machining of Shaft-type Parts with low module axis tooth internal spline Orientation problem, positioning accuracy is high, easy to operate.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of low module axis tooth internal spline clamp for machining in the embodiments of the present invention.
Appended drawing reference is as follows:
1, coning sleeve, 2, elastic collet, 3, mould, 4, spacer, 5, top, 6, collet mandril, 7, oil cylinder pull rod, 8, oil Cylinder, 9, pull bar screw, 10, T-nut, 11, spacer pin, 12, workpiece to be processed.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
As shown in Figure 1, a kind of low module axis tooth internal spline clamp for machining, has mould 3, mould 3 is connected by screw to On platen, mould 3 is provided centrally with hole, and tapered set 1 is connected by screw in hole, and 1 bottom of coning sleeve passes through screw Be connected with top 5, coning sleeve 1 is provided centrally with elastic collet 2, be provided on elastic collet 2 with 1 taper of coning sleeve be adapted Taper, and can be slided up and down in coning sleeve 1, it is provided with via hole on top 5, spacer 4 is provided in via hole, elastic collet 2 is logical The pull bar screw 9 crossed in spacer 4 is coupled with the collet pull rod 6 that top 5 bottom is arranged, and 6 other end of collet pull rod passes through T-nut 10 connect with oil cylinder pull rod 7, and oil cylinder pull rod 7 is driven by oil cylinder 8.
In the present embodiment, the mould 3 is in taper type.
In the present embodiment, the taper angle of the coning sleeve 1 is not more than 5 °.
In the present embodiment, 2 side of elastic collet is provided with vertical waist type groove, sets on mould corresponding with waist type groove Pin hole is set, the spacer pin 11 of the restricted elastic collet abjection of setting in pin hole.
In the present embodiment, the spacer 4 and top 5 via hole interference fit, between pull bar screw 9 and spacer 4 can from By sliding.
For the present embodiment in use, when workpiece to be machined is placed on fixture, oil cylinder 8 passes through the downward strain clamp of oil cylinder pull rod 7 Head pull rod 6, collet pull rod 6 tense downwards elastic collet 2, the slide downward in coning sleeve 1 of elastic collet 2 by pull bar screw 9 And reduce, realize inner hole of workpiece tensioner and centering;After the completion of work pieces process, oil cylinder 8 passes through the upward top clip head pull rod of oil cylinder pull rod 7 6, collet pull rod 6 is upwards jacked up elastic collet 2 by spacer 4, and collet swell can easily take out workpiece.
Described is only the preferred embodiment of the utility model, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
