Description
Technical field
The utility model relates to the clamp for machining of axial workpiece, particularly processes the anchor clamps of eccentric shaft.
Background technology
Eccentric axial workpiece is being added man-hour, generally adopting the turning of chuck clamping, the eccentric throw precision of the eccentric shaft part that this installation way processes is low, only suitable single-piece production or small serial production.In order to improve the eccentric throw precision of eccentric shaft part, generally adopt special fixture clamping as shown in figure 12 to carry out the processing of eccentric shaft at present, the clamp body of these anchor clamps and lathe spindle coaxial line, be eccentric chuck 27 off-centre, though can improve the eccentric throw precision of eccentric shaft part, have following defective:
One, eccentric chuck 27 adopts 6 claws 26 that 5mm is thick, and the tapered sleeve 25 of anchor clamps compresses the conical surface of claw 26 to realize the clamping of part, and this structure is because tapered sleeve 25 is few with the contact area of claw 26 conical surfaces, so cause the wearing and tearing of tapered sleeve 25 and eccentric chuck 27 easily.
Two, the eccentric throw of part is to realize by the offset of eccentric chuck 27, so must be equipped with different eccentric chucks for the eccentric shaft part of different eccentric throws, this will cause processing site to have more eccentric chuck, and management is unfavorable for remodeling.
Three, the eccentric shaft clamp for machining of this kind structure is when parts fixation, and the adjustment of eccentric throw is stranded energy very much.
Summary of the invention
