Description

The oil cylinder special fixture
Technical field
The utility model belongs to be used to processing the field, fixture field of oil cylinder seamless steel pipe, is specifically related to a kind of oil cylinder special fixture.
Background technology
At present, in the process of carrying out oil cylinder, generally can use common universal fixturing, the clamping of tubing and loose unloading often need to use a lot of man-hours, reduced to a certain extent operating efficiency, and the position of some fixture too closely also is easier to impact processing and speed because of the distance machined surface, the fixture of prior art mainly adopts external card to press or conical extrusion, its clamp-press type makes oil cylinder lack the location of center and end face, complex operation and precision are lower, and conical extrusion is because blocking both ends of the surface, be not used in the processing with end face and internal diameter, thereby efficiency is lower in actual applications for the fixture of use prior art, and safety in utilization is also poor, directly affect to a certain extent the quality of product, be difficult to meet the needs of existing market.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, safety in utilization good, easy and simple to handle and oil cylinder special fixture that service precision is high.
The technical scheme that realizes the utility model purpose is: a kind of oil cylinder special fixture, comprise expansion set, snap ring, apical ring, thrust ball bearing, bullet, handle of a knife, lock-screw and round nut, described handle of a knife and the welded setting of described bullet, described bullet is arranged in described expansion set, described snap ring is arranged on the outside, an end of described expansion set, described snap ring and apical ring are equipped with in described bullet and handle of a knife junction, described thrust ball bearing is arranged between described expansion set end and described apical ring, described snap ring is fixedly connected with by lock-screw with described apical ring, described expansion set coordinates pressure to stop described thrust ball bearing with described apical ring under the pressure of snap ring, described round nut is arranged on the outside of described apical ring, described round nut and described apical ring are welded and fixed.
Described expansion set away from snap ring one end inboard, be provided with dovetail groove, the outside is provided with two parallel half slots, is axially arranged with six grooves.
Described snap ring is the annulus integral body that two semicircular ring form.
Described handle of a knife is the Morse's cone body.
The utlity model has positive effect: of the present utility model simple in structure, safety in utilization is good, simple and quick and precision is higher, can not affect the processing of parts, can effectively improve working (machining) efficiency, and practicality is good.
The accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is construction profile figure of the present utility model;
Fig. 2 is cut-away structure chart shown in Figure 1.
The specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of specific embodiment of the present utility model, and wherein Fig. 1 is construction profile figure of the present utility model; Fig. 2 is cut-away structure chart shown in Figure 1.
See Fig. 1 and Fig. 2, a kind of oil cylinder special fixture, comprise expansion set 1, snap ring 2, apical ring 3, thrust ball bearing 4, bullet 5, handle of a knife 6, lock-screw 7 and round nut 8, described handle of a knife 6 and the welded setting of described bullet 5, described bullet 5 is arranged in described expansion set 1, described snap ring 2 is arranged on the outside, an end of described expansion set 1, described snap ring 2 is equipped with in described bullet 5 and handle of a knife 6 junctions with apical ring 3, described thrust ball bearing 4 is arranged between described expansion set 1 end and described apical ring 3, described snap ring 2 is fixedly connected with by lock-screw 7 with described apical ring 3, described expansion set 1 coordinates pressure to stop described thrust ball bearing 4 with described apical ring 3 under the pressure of snap ring 2, described round nut 8 is arranged on the outside of described apical ring 3, described round nut 8 is welded and fixed with described apical ring 3.In the present embodiment, at bullet and handle of a knife junction, be provided with external screw thread, it is threaded with round nut by external screw thread, and it is when installing workpiece, and round nut is screwed down, driving apical ring and snap ring together rotates, now, round nut promotes apical ring, thrust ball bearing and expansion set and moves to left together, makes bullet be pressed into expansion set, the outside distortion of expansion set simultaneously tightly is pressed on the inner circle of oil cylinder, and workpiece is stepped up; During the loose unloading workpiece, by the hook spanner loose unloading round nut that makes progress, make expansion set separate and get final product with bullet.
Described expansion set 1 away from snap ring 2 one end inboards, be provided with dovetail groove 11, the outside is provided with two parallel half slots 12, is axially arranged with six grooves 13.Groove at the end away from snap ring of expansion set is conducive to be out of shape under the tension force of expansion set centrum, and the effective compensator or trimmer pressure of these grooves, improve its stability in use in use.
Described snap ring 2 is the annulus integral body that two semicircular ring form.Adopt two semi-circular structure and be connected and fixed by clamping screw, it can facilitate the installation of snap ring, and can well block the pressure snap ring after its combination, and can not affect whole assembling and use, convenient and swift.
Described handle of a knife 6 is the Morse's cone body.Structure for this reason is set, facilitates the fixture quick-replaceable.
The present embodiment in use, can carry out by hook spanner the dismounting of round nut, and its round nut drives apical ring and rotates together, completes dismounting.And the utility model weight is lighter, versatility is also stronger, generally at pipe fitting, uses up cun single a needs and frequently changes fixture, easy to use.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
