Description
Technical field:
The utility model relates to a kind of cylinder barrel turning tool.
Background technology:
At present, length and the diameter of hydraulic jack exceed 10 than major part, cylinder tube length is generally longer, and the processing of cylinder tube is all first that inner hole of cylinder honing is good, then carries out the length of cylinder barrel, chamfering, the turning processing such as screw thread, because endoporus has processed, roughness and dimensional accuracy are higher, so design and add man-hour all taking inner hole of cylinder as smart benchmark, can obtain more accurate size after cylinder barrel processing.But because cylinder barrel blank is all generally to be processed by cold-drawn, there is certain Wall-Thickness Difference, ensure the axiality of cylindrical and external screw thread processing, necessary first processing technology step, frame centre frame.
Referring to Fig. 1, in existing threading cylinder barrel manufacturing procedure, plug 3 or elastic expansion sleeve (elastic central spindle) that use is fixed on cylinder barrel 2 end faces hold out against clamping in conjunction with live centre 4 and tail stock 5, need to be in advance to cylinder barrel planar end surface when practical operation, can only processing excircles after clamping, external threading, technique step, can not process end face and end chamfering.
Before processing technology step, cylinder barrel need be got length, planar end surface, again with the end face upper plug head that processes or top the holding out against of elastic expansion sleeve elasticity tailstock rotation, processing excircles and external screw thread, processing technology step provides benchmark for the processing of internal thread cylinder barrel, operation is more, affects operating efficiency.
Existing technique adds man-hour for external screw thread cylinder barrel, the first planar end surface of the end of thread, and the cylinder bottom that then turns around is held end face level with both hands and is got length, finally reverses end for end again, machining screw and cylindrical.Planar end surface processing generally, by processing technology step in advance, as technological datum, is generally used first cylinder barrel school centre frame mainly with cylinder barrel cylindrical frame centre frame, same batch of this centre frame folder Excircle machining all.
In whole operation, technique step is not done at cylinder barrel two ends, and only using unprocessed cylinder barrel cylindrical as benchmark, but whether end face is vertical very important with endoporus, will affect the quality of cylinder barrel postorder machining accuracy and whole oil cylinder.Because cylinder barrel generally all exists Wall-Thickness Difference, and centre frame meeting wearing and tearing in batch machining process, so can not ensure after planar end surface that cylinder barrel end face is vertical with endoporus, will affect the precision of subsequent handling and the quality of whole oil cylinder.
Summary of the invention:

Compared with the prior art, the beneficial effects of the utility model are embodied in:
Elastic expansion sleeve is quiet contact with inner wall of cylinder, is not sliding pair or revolute pair, adds and plays a supportive role man-hour in cylinder barrel turning, rotate around the spindle together with cylinder barrel, and can relative sliding or rotation between cylinder barrel, can not damage the inner hole of cylinder surface of the processing of honing.
While making the utility model frock threading cylinder barrel, the first order planar end surface, inner bore chamfering, car bevel for welding, planar end surface after the second order turns around, gets length, turning, external screw thread, technique step (internal thread cylinder barrel machining needs).Reduce by an order compared with existing frock and technique, ensured the perpendicularity of end face and endoporus, improved efficiency, ensured dimensional accuracy, ensured quality, reduced working strength.
The utility model frock is taking inner hole of cylinder as machining benchmark, can an order planar end surface, get length, end face chamfering, Excircle machining, external threading, technique step.After processing, cylinder barrel end face is vertical with inner hole of cylinder, can be good at ensureing cylinder barrel Geometrical Tolerance Principle, meets oil cylinder assembling instructions for use, ensures oil cylinder performance.
Elastic expansion sleeve acts on inner wall of cylinder, taking inner hole of cylinder as benchmark, has with a certain distance from cylinder barrel end face, and avoid cylinder barrel end face to add and interfered man-hour, and can end face chamfering, reduce clamped one time, reduce by a procedure.
Elastic expansion sleeve and spacer are replaceable structure, can adapt to process the cylinder barrel of different cylinder diameters.Be threaded connection locking between the two, connecting rod and multidiameter have ladder protection structure.
