Description
Technical field
The utility model relates to a kind of device of machining hole, specifically is the eccentric rack device of clamping cutter on the lathe.
Background technology
On lathe, be processed with hole workpiece, if can not just determine machining deviation so usually to occur in the center, hole, do not reach regulation machining accuracy on the drawing, make the semi-finished product of finishing former procedures become defective work, enterprise suffers a loss and can not finish the product processing tasks on schedule.Process porose workpiece, it generally is because lathe when this workpiece of processing, is failed the fine center that aligns that the center, hole produces deviating cause; Also owing to aligned the center, but fail to grind during drill sharpening, make to add correctly to center man-hour.The knife rest of lathe clamping cutter is mounted on the planker in addition and since transmission that planker is moved pay between error, causing that center cutter line and machine tool chief axis center line are out-of-line needs to adjust center cutter.
Summary of the invention
The utility model purpose is the deviation that produces during at boring cutlery sharpening; Error between the transmission that planker is moved is paid causes error between center cutter line and spindle centerline, adjusts the defective of difficulty of error.The utility model purpose is achieved in that it is made up of trombone slide, regulating shaft, the bearing support of internal thread hole an end, it is characterized in that eccentric shaft, resilient sleeve, tightening member, axial adjustment nut in addition, trombone slide is in regulating shaft, be regulating shaft in the axis hole of eccentric shaft, and be contained on the bearing support, the endoporus of eccentric shaft one end has internal conical surface, outer conical surface is arranged on the resilient sleeve, be enclosed within regulating shaft, and in the female cone face of eccentric shaft one end, the tightening member is connected with eccentric shaft one end, is connected with resilient sleeve again, and the axial adjustment nut is connected with the eccentric shaft other end.Described bearing support is to be made of following of the eccentric frame seat of honour, eccentric frame, gag, screw, the housing screw of being with translot.There is dovetail groove at the eccentric frame seat of honour, and following of eccentric frame has dovetail, and dovetail groove is connected with dovetail, and gag embeds between dovetail groove and dovetail, and gag is fixed by screw, and eccentric frame has housing screw on the seat of honour.

The specific embodiment
Be an embodiment of the present utility model below.It is made up of trombone slide nut 1, trombone slide 2, regulating shaft 3, jump ring 4, packing ring 5, axial adjustment nut 6, eccentric shaft 7, the eccentric frame seat of honour 8, housing screw 9, clamp nut 10, resilient sleeve back-up ring 11, screw 12, resilient sleeve 13, following 14 on eccentric frame, gag 17; At trombone slide 2 one ends trombone slide groove 22 is arranged, the other end has the trombone slide internal thread hole.Trombone slide 2 is loaded in the regulating shaft 3, and projection 21 is arranged on the regulating shaft 3, and projection 21 other ends place trombone slide groove 22, and the two one-tenth is slidingly matched.Regulating shaft 3 is inserted in the endoporus of eccentric shaft 7, and by soket head cap screw 20 connections, jump ring 4 is arranged on regulating shaft 3 successively, packing ring 5, axial adjustment nut 6, axial adjustment nut 6 is connected with eccentric shaft 7 threaded one ends, eccentric shaft 7 is loaded on the eccentric frame seat of honour 8, the internal conical surface of eccentric shaft 7 other ends cooperates with resilient sleeve 13 outer conical surface on being enclosed within regulating shaft 3, the tightening member is connected with resilient sleeve 13, described tightening member is by clamp nut 10, resilient sleeve back-up ring 11, screw 12 constitutes, resilient sleeve 13 1 ends and are connected by screw 12 between clamp nut 10 and resilient sleeve back-up ring 11.The eccentric frame seat of honour 8 is connected with following 14 on eccentric frame, on the described eccentric frame seat of honour 8 dovetail groove 16 and translot 18 are arranged, the eccentric frame seat of honour 8 is connected with housing screw 9, on following 14 on the eccentric frame dovetail 15 is arranged, dovetail 15 embeds dovetail groove 16, and have gag 17 to embed, gag 17 is fixed on the eccentric frame seat of honour 8 by screw 19.Described trombone slide 2 other ends have trombone slide nut 1, and the two is to be threaded.
Chuck inserts an end of trombone slide 2 during use, screws in internal thread hole, and trombone slide nut 1 is pulled outwardly, and drives trombone slide 2 axial outer moving; Rotatably compress nut 10, make resilient sleeve 13 press the female cone hole of eccentric shaft 7, resilient sleeve 13 produces strain, and chuck is tightened up.If bit central and spindle centerline on the chuck are inconsistent, unscrew housing screw 9 earlier, translot 18 gaps are increased, upper-lower position is by eccentric rotation axis 7, make angle of eccentric shaft 7 deflections, front and back position is by regulating the position between following 14 on the eccentric frame seat of honour 8 and the eccentric frame; Make bit central and spindle centerline on same straight line, the drill bit axial location, makes to be enclosed within that eccentric shaft 7 raises nodal axisns 3 and trombone slide 2 moves axially to adjusting nut 6 by turning cylinder; Screw housing screw 9 after adjustment is finished, make the eccentric shaft 7 and the eccentric frame seat of honour 8 fastening.
The utlity model has overcome the deviation that the boring cutlery of packing into produces when sharpening, and the aperture knife tool center line that causes of other factors and the deviation of the inconsistent generation of spindle centerline, easy to adjust, reliable, structure is uncomplicated.
