Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A place sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises mandrel 1, and the rear portion of mandrel is provided with taper shank 11, and taper shank 11 is for inserting lathe tailstock when turnery processing.Tapered sleeve 4 is rotatably arranged on the front end of mandrel 1 by one group of bearing 7, and bearing 7 is by big nut 6 axial restraint of mandrel 1 front end, and the diameter of tapered sleeve 4 is that large rear end, front end is little, and the outer end of tapered sleeve 4 is installed with end cap 5.Elasticity stock 2 is sleeved on mandrel 1 rotationally, elasticity stock 2 comprises elastic expansion-sleeve portion 201 and extending sleeve portion 202, elastic expansion-sleeve portion 201 is in cup shape, be sleeved on outside tapered sleeve 4, the openend in elastic expansion-sleeve portion 201 is provided with the inner conical surface 203 that mates with tapered sleeve 4 and contacts with tapered sleeve 4, elastic expansion-sleeve portion 201 is provided with some equally distributed radial elongated slots 204, the quantity of elongated slot 204 can be determined according to the external diameter size in elastic expansion-sleeve portion 201, in the present embodiment, the quantity of elongated slot 204 is 12, elongated slot 204 makes elastic expansion-sleeve portion 201 have during relative displacement can expand outwardly at itself and tapered sleeve 4.Extending sleeve portion 202 is rotatably sleeved on mandrel 1, and extending sleeve portion 202 effect is to abdicate space, and lathe tool can be made to have the seam of enough space turning cylinder bodies or internal thread etc., and the length in extending sleeve portion 202 can be determined according to the needs of processing.Back-moving spring 3 to be sleeved on mandrel 1 and to be against and is axially fixed in cushion block 12 on mandrel 1 with on the inner bottom surface in elastic expansion-sleeve portion 201, plane bearing 8, stop collar 9 and adjusting nut 10 are arranged on the mandrel 1 behind the extending sleeve portion 202 of elasticity stock 2 successively, adjusting nut 10 is threaded with mandrel 1, by adjustment adjusting nut 10, axial location between adjustable elastic expansion-sleeve portion 201 and tapered sleeve 4, thus make elastic expansion-sleeve portion 201 tensioner in cylinder inner bore or unclamp.
Add man-hour carrying out turning cylinder body, one end of cylinder body is clamped by scroll chuck, the elastic expansion-sleeve portion 201 of elasticity stock 2 of the present utility model is inserted in the endoporus of the cylinder body other end, and taper shank 11 is inserted in lathe tailstock, rotate adjusting nut 10 thus promote elasticity stock 2 and be moved to the left in (in Fig. 1 direction), under inner conical surface 203 acting in conjunction in tapered sleeve 4 and elastic expansion-sleeve portion 201, elastic expansion-sleeve portion 201 expands outwardly, make elastic expansion-sleeve portion 201 tensioner in the endoporus of cylinder body, and be cylinder body centering, again scroll chuck is pressed from both sides co-clip tight, now can carry out turnery processing to the cylinder body end of fixture tensioner, when carrying out turnery processing, elastic expansion-sleeve portion 201 rotates together with cylinder body (elastic expansion-sleeve portion 201 rotates around mandrel 1).After completing, cylinder body turns around and repeats the turnery processing that above-mentioned steps can complete cylinder body two ends, namely whole turning, clamping completes for twice, decrease clamping times, ensure the machining accuracy of cylinder body, enhance productivity, reduce the workload of workman, alleviate the labour intensity of workman, reduce production cost.
