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 the turning attachment of a kind of turning swivel nut part two ends endoporus.
Background technology
When processing swivel nut part two ends endoporus, scroll chuck is usually adopted to be realized the positioning and clamping of workpiece by the cylindrical of workpiece.Scroll chuck has stronger versatility, without the need to manufacturing specially and the advantage such as higher centering precision, but when using scroll chuck to Workpiece clamping, because itself and processing work contact area are less, clamping force in unit are is larger, particularly when workpiece is thinner, more easily there is pinching deformation in workpiece, causes workpiece processing quality to be difficult to ensure.
Summary of the invention
In order to can problems of the prior art be overcome, the object of this invention is to provide a kind of swivel nut inner bore of part lathe for machining fixture, this turning attachment adopts one section of thin-walled of clamp body front end as setting element and clamping element, adopt tapered sleeve as clamp system, clamp structure is compact, reliably simple to operation, positioning precision is very high, and crudy is easy to ensure, has very strong practicality.
The object of the invention is to be achieved through the following technical solutions:
A kind of swivel nut inner bore of part lathe for machining fixture, it is characterized in that: this turning attachment comprises clamp body, nut, tapered sleeve and back-moving spring, be arranged on lathe spindle with the clamp body of seam location by transition disc, the front end of clamp body is the thin-walled of the tubbiness with external taper, and the rear end external diameter of thin-walled is greater than front end external diameter; Internal diameter and the swivel nut external diameter to be processed of thin-walled are suitable; Internal taper and the suitable tapered sleeve of thin-walled external taper are sleeved on outside thin-walled; Back-moving spring is sleeved on thin-walled place and between the screw thread step and tapered sleeve at clamp body rear portion; Nut is through thin-walled and tapered sleeve and be threaded connection with clamp body.
In the present invention, be provided with the corrector loop of adjustment clamp body position in clamp body rear end.The internal taper of tapered sleeve is identical with thin-walled external taper.Nut is provided with nut rotation handle patchhole.
Operation principle of the present invention is: first according to swivel nut part positioning datum (cylindrical) the diameter dimension size of required processing, 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, processing tapered sleeve internal taper (tapered sleeve internal taper=thin-walled external taper).Then in the thin-walled endoporus of clamp body front end, pre-determined bit is completed with swivel nut part outer.Nut inserts nut rotation handle (not shown), tightening nut, tapered sleeve is moved to the left, force the thin-walled homogeneous deformation of clamp body front end, centering clamping swivel nut part.When after the processing completing swivel nut part one end endoporus, loosening nut slightly, the back-moving spring being in tapered sleeve left end is upspring, and forces tapered sleeve to move to right, swivel nut part is unclamped, takes out the processing that swivel nut part turns around again to complete by preceding method positioning and clamping and swivel nut part other end endoporus.The swivel nut part machined finally is taken out by preceding method.
The present invention adopts thin-walled external taper and the design of tapered sleeve internal taper of clamp body front end, ensure that the reliability of clamp swivel nut part.The present invention adopts back-moving spring to design, and swivel nut part is dismantled convenient, alleviates the labour intensity of workman.The present invention arranges corrector loop on clamp body, by corrector loop adjustable clamp body, ensures that swivel nut axis of workpiece is consistent with the axis of machine tool chief axis, thus reaches coaxial accuracy requirement, ensure the crudy of part.
Compared with prior art, the present invention has the following advantages: the present invention adopts the thin-walled design of clamp body front end that the location of workpiece and clamping are carried out simultaneously, ensure the uniformity of the endoporus of swivel nut part and the axial line of cylindrical, meet the axiality requirement between swivel nut part outer and endoporus; Meanwhile, clamp body front end thin-walled and swivel nut part outer are full surface contact, and contact area is comparatively large, and the clamping force in unit are is less, and during the thinner swivel nut part of clamping wall thickness, the pinching deformation of swivel nut part is less, and part crudy is easy to ensure.

Detailed description of the invention
A kind of swivel nut inner bore of part lathe for machining fixture, see Fig. 1, this turning attachment comprises clamp body 2, back-moving spring 4, tapered sleeve 6, nut 3 and nut rotation handle (not shown).Be arranged on lathe spindle with the clamp body 2 of seam location by transition disc; Back-moving spring 4 be sleeved on clamp body 2 thin-walled place, front end and between clamp body 2 screw thread step and tapered sleeve 6; Tapered sleeve 6 is sleeved on the thin-walled place, front end of clamp body 2; Nut 3 passes front end thin-walled and the tapered sleeve 6 of clamp body 2, adopts be threaded with clamp body 2; Nut rotation handle (not shown) adopts matched in clearance to be connected with nut 3.
Add man-hour, swivel nut part 8 after pre-determined bit, completes positioning and clamping by tightening nut 3 with cylindrical in the endoporus of clamp body 2 front end thin-walled; Clamp body 2 arranges corrector loop 1, by the position of corrector loop 1 adjustable clamp body 2, ensures that swivel nut part needs the axis of machining hole consistent with the axis of machine tool chief axis, thus meet the coaxial accuracy requirement in hole, ensure the crudy of part.When after the processing completing swivel nut part one end endoporus, loosening nut slightly, the back-moving spring being in tapered sleeve left end is upspring, and forces tapered sleeve to move to right, swivel nut part is unclamped, takes out the processing that swivel nut part turns around again to complete by preceding method positioning and clamping and swivel nut part other end endoporus.The swivel nut part machined 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, and adopt tapered sleeve as clamp system, clamp structure is compact, reliably simple to operation, and positioning precision is very high, and crudy is easy to ensure, has very strong practicality.
