Abstract
The invention discloses a positioning and clamping device. The positioning and clamping device comprises a clamp body, a compaction sleeve and a gland nut. The clamp body is a step shaft provided with an external spline, and a cone is arranged on the major diameter surface of the external spline. The compaction sleeve is a hollow cone, and an external splaine is arranged on the surface of the compaction sleeve. An inner hole of the compaction sleeve and the outer circle of the clamp body are in precision positioning clearance fit, the coaxiality requirement is guaranteed, and the gland nut is connected with the external thread end of the clamp body. By screwing the gland nut, the clamp body and the major diameter conical face of the external spline of the compaction sleeve can be fit with the major diameter surface of an internal spline of a workpiece, and then the workpiece is clamped and positioned. The positioning and clamping device is ingenious in structure design and high in positioning precision and can be widely used for grinding and turning various workpieces with internal splines.
Description
[technical field]
The present invention relates to Machining Technology field, be applicable to internal spline zero particularly to one
The positioning clamping device of part processing.
[background technology]
In the part course of processing with internal spline, often run into flower in design requires to need
Key and outer round surface have the situation that axiality requires, current processing method is all to take mandrel to press from both sides
Tool, mandrel surface is cylindrical, and for convenient mounting and clamping, mandrel cylindrical has with spline aperture
Certain gap, the method cannot ensure higher axiality requirement, and processing effect is less managed
Think.
[summary of the invention]
In view of this, for overcoming the deficiencies in the prior art, the present invention provides the clamping of a kind of location
Device, easy to install and use, positioning precision is high, can be widely used in various band internal spline
Workpiece grinding and turnery processing.
For achieving the above object, technical scheme is as follows:
A kind of positioning clamping device, including clamp body, clamping sleeve and clamp nut, described fixture
Body is the Step Shaft being provided with external splines, and described clamping sleeve is the cone of hollow, its endoporus with
Described clamp body cylindrical is matched in clearance, described clamp nut and the external screw thread of described clamp body
End connects.
Further, the surface, external splines big footpath of described clamp body is cone shape, and it is large and small
End diameter footpath large and small with workpiece internal spline size is suitable.Particularly as follows: described cone is big
End diameter is slightly larger than workpiece internal spline big footpath size, and it is big that end diameter is slightly less than workpiece internal spline
Footpath size.
The surface of described clamping sleeve is provided with external splines, its large and small end diameter and workpiece internal spline
Large and small footpath size is suitable.Described external splines outside diameter is slightly larger than the big footpath of workpiece internal spline
Size, end diameter is slightly less than workpiece internal spline big footpath size.
Described clamping sleeve endoporus uses the matched in clearance of precision positioning with clamp body cylindrical, it is ensured that with
Axle degree requirement.
During use, tighten clamp nut and can make described clamp body and the clamping sleeve external splines big footpath conical surface
Fitting in surface, footpath big with workpiece internal spline, thus realizes the clamping to workpiece and location.
The invention has the beneficial effects as follows, smart structural design, it is ensured that the axiality of processing is wanted
Asking, easy to install and use, positioning precision is high, can be widely used in the work of various band internal spline
Part grinding and turnery processing.
[accompanying drawing explanation]
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, under
The accompanying drawing used required in embodiment or description of the prior art will be briefly described by face,
It should be evident that the accompanying drawing in describing below is only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure, 1, clamp body, 2, clamping sleeve, 3, clamp nut, 4, workpiece.
[detailed description of the invention]
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technology in the embodiment of the present invention
Scheme is clearly and completely described, it is clear that described embodiment is only the present invention
A part of embodiment rather than whole embodiments.Based on the embodiment in the present invention, this
It is every other that field those of ordinary skill is obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
With reference to Fig. 1, a kind of positioning clamping device, including clamp body 1, clamping sleeve 2 and compression
Nut 3, clamp body 1 is the Step Shaft being provided with external splines, described fixture, the big footpath of external splines of 1
Surface is cone shape, and its large and small end diameter footpath large and small with workpiece internal spline size is fitted mutually
Join, described cone outside diameter is slightly larger than workpiece 4 internal spline big footpath size, end diameter
It is slightly less than workpiece 4 internal spline big footpath size.
Described clamping sleeve 2 is positioned at the middle part of clamp body 1, and it is the cone of hollow, clamping sleeve
2 endoporus and clamp body 1 cylindrical are matched in clearance, it is ensured that the axiality requirement of processing.Compress
The surface of set 2 is provided with external splines, its large and small end diameter and workpiece 4 internal spline large and small footpath chi
Very little suitable.Described external splines outside diameter is slightly larger than workpiece 4 internal spline big footpath size, little
End diameter is slightly less than workpiece 4 internal spline big footpath size.
Clamp nut 3 is connected with the male end of described clamp body 1, phase tight with clamping sleeve 2
Neighbour, compresses location to workpiece 4 together.
During use, tighten clamp nut 3 and described clamp body 1 and clamping sleeve 2 external splines can be made big
The footpath conical surface is fitted with surface, workpiece 4 internal spline big footpath, thus realizes the clamping to workpiece 4 and determine
Position.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
Should be included within the scope of the present invention.
