Abstract
The invention relates to a lathe clamping fixture for an eccentric shaft. The lathe clamping fixture for the eccentric shaft is characterized by comprising a body which is cylindrical, wherein the body is provided with an eccentric hole which is communicated with two end surfaces; the axis of the eccentric hole is parallel to the axis of the body; the side wall of the body is provided with a screw hole; the screw hole is communicated with the eccentric hole; and the axis of the screw hole vertically intersects with the axis of the body and the axis of the eccentric hole; the screw hole is internally provided with a bolt; and the length of the part on the bolt with a thread is greater than the length of the screw hole. After the eccentric shaft is clamped by adopting the clamping fixture, turning operation is carried out on the lathe, repeated correction is not required, the machining efficiency is high, and the lathe clamping fixture for the eccentric shaft is suitable for mass production.
Description
Technical field
The present invention relates to a kind of lathe clamping anchor clamps, is the lathe clamping anchor clamps that are used to process eccentric shaft specifically.
Background technology
At present, in field of machining, when using lathe that eccentric shaft is carried out the turning operations; Must use scroll chuck or chuck to proofread and correct the eccentric shaft center in advance, this correction operation is comparatively loaded down with trivial details, and difficulty is big; Eccentric shaft of every processing; All must carry out the correction operation of repetition, operations efficient is low, is inappropriate for production in enormous quantities.
Summary of the invention
The problem that the present invention will solve provides a kind of eccentric shaft with lathe clamping anchor clamps, cuts operation in the enterprising driving of lathe after adopting this clamping anchor clamps clamping eccentric shaft, need not to repeat to proofread and correct, and working (machining) efficiency is high, is suitable for producing in enormous quantities.
For addressing the above problem, take following scheme:
Eccentric shaft of the present invention is to comprise body with the characteristics of lathe clamping anchor clamps, and body is cylindric.The eccentric orfice, the axis of eccentric orfice and the parallel axes of body that are communicated with both ends of the surface are arranged on the said body.On the sidewall of said body screw is arranged, screw is connected with eccentric orfice, and the axis of screw and body axis, eccentric orfice axis all intersect vertically.In the said screw bolt is arranged, be threaded the length of the length of part on the bolt greater than screw.
Further improvement project of the present invention is that said screw is positioned on the body sidewall position near the upper surface, thereby is convenient to change the eccentric shaft workpiece.
Take such scheme, have the following advantages:
Because eccentric shaft of the present invention with on the lathe clamping anchor clamps eccentric orfice being arranged, when eccentric shaft is carried out clamping, screws out bolt earlier; Axis body with eccentric shaft partly stretches in the eccentric orfice again, is adjacent to fully until the eccentric shaft end face till the upper surface of these anchor clamps; Then, bolt is screwed in screw with the locking of eccentric shaft axis body, at this moment, the axle center of eccentric shaft end face and the axis coinciding of anchor clamps; At last, these anchor clamps are communicated with eccentric shaft are fixed on together on the scroll chuck or chuck on the lathe, and carry out to process after the cent(e)ring operation.When processing follow-up eccentric shaft, only need bolt is outwarded winding, change eccentric shaft again and get final product, need not to carry out again cent(e)ring, thereby make working (machining) efficiency improve, be suitable for producing in enormous quantities.
Description of drawings
Fig. 1 is the structural representation of eccentric shaft of the present invention with lathe clamping anchor clamps;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the user mode sketch map of eccentric shaft of the present invention with lathe clamping anchor clamps.
The specific embodiment
As depicted in figs. 1 and 2, eccentric shaft of the present invention comprises body 1 with lathe clamping anchor clamps, and body 1 is cylindric.The eccentric orfice 2 that is communicated with both ends of the surface is arranged, the parallel axes of the axis of eccentric orfice 2 and body 1 on the said body 1.On the sidewall of said body 1 screw is arranged, screw is positioned on body 1 sidewall position near the upper surface in the present embodiment.Said screw is connected with eccentric orfice 2, and the axis of screw and body 1 axis, eccentric orfice 2 axis all intersect vertically.Bolt 3 is arranged in the said screw, be threaded the length of the length of part on the bolt 3 greater than screw.
As shown in Figure 3, during use, eccentric shaft workpiece 4 axis bodies to be processed are partly stretched in the eccentric orfice 2 of eccentric shaft of the present invention with lathe clamping anchor clamps, with bolt 3 with its locking.Again with eccentric shaft of the present invention with lathe clamping clamps on scroll chuck on the lathe or chuck 5, and carry out can processing after the cent(e)ring operation.During the processing subsequent workpiece, only need bolt 3 is screwed out, behind the replacing eccentric shaft workpiece 4, can process with bolt 3 lockings again, need not to carry out once more cent(e)ring.
Claims (2)
1. eccentric shaft is characterized in that comprising body (1) with lathe clamping anchor clamps, and body (1) is cylindric; The eccentric orfice (2) that is communicated with both ends of the surface is arranged, the parallel axes of the axis of eccentric orfice (2) and body (1) on the said body (1); On the sidewall of said body (1) screw is arranged, screw is connected with eccentric orfice (2), and the axis of screw and body (1) axis, eccentric orfice (2) axis all intersect vertically; Bolt (3) is arranged in the said screw, be threaded the length of the length of part on the bolt (3) greater than screw.
2. eccentric shaft as claimed in claim 1 is with lathe clamping anchor clamps, it is characterized in that said screw is positioned on body (1) sidewall position near the upper surface.
