The screw sleeve part inner hole processing lathe clamp has the advantages that the structure is compact, the operation is simple, convenient and reliable, the positioning precision is very high, the processing quality can be easily ensured, and higher practicability is realized.
Description
Technical field
The present invention relates to a kind of turning attachment, specifically a kind of turning attachment of turning swivel nut part two ends endoporus.
Background technology
When swivel nut part two ends endoporus is processed, the cylindrical positioning for realizing workpiece for generally workpiece being passed through using scroll chuck
With clamping.Scroll chuck has the advantages that stronger versatility, need not be specifically manufactured and higher centering precision, but uses three-jaw
When chuck is to Workpiece clamping, because it is less with processing absorption surface area, the clamping force in unit area is larger, particularly works as work
When part wall thickness is relatively thin, workpiece is more easy to pinching deformation, causes workpiece processing quality to be difficult to ensure that.
The content of the invention
In order to be able to overcome problems of the prior art, it is an object of the invention to provide a kind of processing of swivel nut inner bore of part
Turning attachment, the turning attachment, as setting element and clamping element, is made using one section of thin-walled of clamp body front end using tapered sleeve
For clamp system, clamp structure is compact, reliability simple to operation, and positioning precision is very high, and crudy is easy to ensure, with very
Strong practicality.
The purpose of the present invention is achieved through the following technical solutions：
A kind of swivel nut inner bore of part lathe for machining fixture, it is characterised in that：The turning attachment includes clamp body, nut, cone
Set and back-moving spring, the clamp body positioned with seam is arranged on lathe spindle by transition disc, the front end of clamp body be with
The thin-walled of the tubbiness of external taper, and the rear end external diameter of thin-walled is more than front end external diameter；The internal diameter of thin-walled and swivel nut external diameter phase to be processed
Adaptation；The tapered sleeve that internal taper is adapted with thin-walled external taper is sleeved on thin-walled outside；Back-moving spring is sleeved at thin-walled and is located at
Between the screw thread step at clamp body rear portion and tapered sleeve；Nut passes through thin-walled and tapered sleeve and is threaded connection with clamp body.
In the present invention, in clamp body rear end the corrector loop of adjustment fixture body position is provided with.Outside the internal taper and thin-walled of tapered sleeve
Taper is identical.Nut rotation handle patchhole is provided with nut.
Operation principle of the present invention is：First according to the swivel nut part positioning datum of required processing（It is cylindrical）Diameter dimension is big
It is little, the thin-walled endoporus of the concrete front end of processed clip, thin-walled external taper（1°）And thin-walled extension.According to thin-walled external taper, plus
Work tapered sleeve internal taper（Tapered sleeve internal taper=thin-walled external taper）.Then with the cylindrical thin-walled endoporus in clamp body front end of swivel nut part
In complete pre-determined bit.Nut rotation handle is inserted on nut（Not shown in figure）, tightening nut is moved to the left tapered sleeve, urgent
The thin-walled homogeneous deformation of clamp body front end, centering is set to clamp swivel nut part.After the processing of swivel nut part one end endoporus is completed, slightly
Slightly loosening nut, the back-moving spring in tapered sleeve left end is upspring, and forces tapered sleeve to move to right, and unclamps swivel nut part, takes out swivel nut zero
Part turns around to complete to position the processing with clamping and swivel nut part other end endoporus again by preceding method.Finally press preceding method
The swivel nut part that taking-up is machined.
The present invention is designed using the thin-walled external taper and tapered sleeve internal taper of clamp body front end, it is ensured that clamp swivel nut zero
The reliability of part.The present invention is designed using back-moving spring, dismantles swivel nut part convenient, and the work for alleviating workman is strong
Degree.The present invention arranges corrector loop on clamp body, by the adjustable clamp body of corrector loop, it is ensured that swivel nut axis of workpiece and lathe master
The axis of axle is consistent, so as to reach coaxial accuracy requirement, it is ensured that the crudy of part.
Compared with prior art, the present invention has advantages below：The present invention makes work using the thin-walled design of clamp body front end
The positioning of part and clamping are carried out simultaneously, it is ensured that the endoporus of swivel nut part and the concordance of cylindrical axial line, meet swivel nut part
The cylindrical axiality and endoporus between is required；Meanwhile, clamp body front end thin-walled is cylindrical with swivel nut part to be contacted for full surface, contact
Area is larger, and the clamping force in unit area is less, during the relatively thin swivel nut part of clamping wall thickness, the pinching deformation of swivel nut part compared with
Little, part crudy is easy to ensure.

Specific embodiment
A kind of swivel nut inner bore of part lathe for machining fixture, is shown in Fig. 1, and the turning attachment includes clamp body 2, back-moving spring 4, cone
Set 6, nut 3 and nut rotation handle（Not shown in figure）.The clamp body 2 positioned with seam is arranged on lathe main by transition disc
On axle；Back-moving spring 4 is sleeved at the front end thin-walled of clamp body 2 and is located between the screw thread step of clamp body 2 and tapered sleeve 6；Tapered sleeve 6
It is sleeved at the front end thin-walled of clamp body 2；Nut 3 adopts screw thread through the front end thin-walled and tapered sleeve 6 of clamp body 2 with clamp body 2
Connection；Nut rotation handle（Not shown in figure）It is connected using gap with nut 3.
Plus man-hour, swivel nut part 8 with cylindrical in the endoporus of the front end thin-walled of clamp body 2 after pre-determined bit, by tightening nut 3
Complete positioning and clamp；Corrector loop 1 is set on clamp body 2, the position of clamp body 2 can adjust by corrector loop 1, it is ensured that swivel nut
The axis that part need to process hole is consistent with the axis of machine tool chief axis, so as to meet the coaxial accuracy requirement in hole, it is ensured that part
Crudy.After the processing of swivel nut part one end endoporus is completed, loosening nut slightly, in the back-moving spring bullet of tapered sleeve left end
Rise, force tapered sleeve to move to right, make swivel nut part unclamp, take out swivel nut part turn around again by preceding method complete positioning with clamp with
And the processing of swivel nut part other end endoporus.The swivel nut part for machining finally is taken out by preceding method.
The present invention adopts one section of thin-walled of clamp body front end as setting element and clamping element, using tapered sleeve as clamping
Mechanism, clamp structure is compact, reliability simple to operation, and positioning precision is very high, and crudy is easy to ensure, with very strong reality
The property used.
