Abstract
The utility model relates to a clamping device for buried oil quenching of a gear. The clamping device comprises a support base, an adapter sleeve, a sleeve and a round nut. A gear to be quenched is put on the support base, the adapter sleeve is an inverted cone-shaped cup of which an opening faces downwards and the middle part of the bottom is provided with an open pore, the cup wall of the adapter sleeve is arranged between the support base and a central hole of the gear to be quenched, a round screw is arranged at the upper part of the support base, the round nut is sleeved on the round screw, the round nut is a step-shaped, the large-end step of the round nut faces down, the cup bottom with a hole in the center is arranged on the upper surface of the large-end step of the round nut, the sleeve is arranged at the excircle of the round nut, and the sleeve and the round nut are fixed in the circumferential direction through a pin. Since the inverted cone-shaped adapter sleeve is additionally arranged between the gear to be quenched and the support base and mounted on the large-end step of the round nut, the round nut can be screwed down and screwed off so as to correspondingly realize the fastening and retreating of the adapter sleeve, thereby clamping the gear conveniently and quickly.
Description
Technical field
The utility model relates to a kind of gear embedding oil quenching clamping device.
Background technology
Behind the single gear tooth embedding oil quenching, gear be taken off from lathe, change a unhardened gear again and continue to quench, this process is simple, quick, easy to operate and precision is high, just can enhance productivity and ensure the quality of products.At present, what the installation way of this single gear tooth embedding oil quenching was that the supporting seat of the endoporus of gear and lathe takes is transition fit, be subjected to the impact of gear manufacturing tolerance, the quality of fit of each gear is different, when the shrink range of tolerance on fit was larger, power used when then gear takes out was larger, even needed could take out with the mode of hammering, so not only the time spent long, damage workpiece also easily; When the shrink range of tolerance on fit hour, then the gap of the supporting seat of gear and lathe is larger, bearing accuracy is poor, even does not have the clamping effect, the quality of gear can not be guaranteed.
The utility model content
The purpose of this utility model is to provide a kind of gear to realize that when the monodentate sense of continuity is answered embedding oil quenching quick-clamping can guarantee clamping precision and a kind of gear embedding oil quenching of product quenching quality clamping device simultaneously.
The technical solution of the utility model is: a kind of gear embedding oil quenching clamping device, it comprises supporting seat, also comprise fixing sleeve, sleeve and round nut, gear to be quenched is placed on the supporting seat, described fixing sleeve is opening down and the inverted cone-shaped cup shape of the middle perforate in bottom, the wall of cup of fixing sleeve is located between supporting seat and the gear center hole to be quenched, be provided with round screw rod on the top of described supporting seat, round nut is enclosed within on the screw rod, round nut is stepped, its large end step down, the cup end of middle perforate, be located on the upper surface of the large end step of round nut, cylindrical at described round nut is provided with sleeve, circumferentially fixes by pin between cover and the round nut.
For fastening gear to be quenched better, described fixing sleeve is resilient sleeve.
For handled easily, be provided with operation handle arm at described sleeve.
The technical solution of the utility model is, because at the fixing sleeve for the treatment of to have set up between Quenched Gear and the supporting seat inverted cone-shaped, fixing sleeve is provided in a side of on the large end step of round nut, and by tightening and unclamp round nut and realize the fastening of fixing sleeve and withdraw from, thereby the clamping gear is convenient and swift.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.With reference to accompanying drawing, it comprises supporting seat 7, fixing sleeve 5, sleeve 4 and round nut 3, gear 6 to be quenched is placed on the supporting seat 7, described fixing sleeve 5 is the inverted cone-shaped cup shape of perforate in the middle of the opening down bottom, the wall of cup of fixing sleeve 5 is located between supporting seat and the gear to be quenched, be provided with round screw rod on the top of described supporting seat, round nut 3 is enclosed within on the screw rod, round nut 3 is stepped, its large end step down, the cup end of middle perforate, be located on the upper surface of large end step of round nut 3, is provided with sleeve 4 at the cylindrical of described round nut 3, circumferentially fixes by pin 1 between sleeve 4 and the round nut.For fastening gear to be quenched 6 better, described fixing sleeve 5 is resilient sleeve.For handled easily, be provided with operation handle arm 1 at described sleeve 4.
During work, gear 6 that first will be to be quenched hangs on and is inserted on the supporting seat 7, with portable clamping device, and the round nut 3 on the clamping device is inserted on the screw rod of supporting seat 7, screw round nut 3 with handle 1, fixing sleeve 5 is pressed in the gap of supporting seat and gear center hole, because fixing sleeve 5 is inverted cone-shapeds, nut is got over the moving fixing sleeve 5 of taut band and is moved down, so that the tensile force of fixing sleeve 5 is larger, thereby the bearing accuracy of gear 6 and position stability are better; After gear quenching is complete, unscrew nut, drive on the fixing sleeve and move, until fixing sleeve 5 leaves gear 6 and supporting seat 7, hold handle, clamping device is taken out, more hard-tempered gear is hung the lower support seat, finish the quenching clamping of a gear, whole process Simple fast, and bearing accuracy is high, and positioning stablity is reliable, is suitable for batch automatic production.
Claims (3)
1. gear embedding oil quenching clamping device, it comprises supporting seat, it is characterized in that, also comprise fixing sleeve, sleeve and round nut, gear to be quenched is placed on the supporting seat, described fixing sleeve is opening down and the inverted cone-shaped cup shape of the middle perforate in bottom, the wall of cup of fixing sleeve is located between supporting seat and the gear center hole to be quenched, be provided with round screw rod on the top of described supporting seat, round nut is enclosed within on the screw rod, and round nut is stepped, its large end step down, the cup end of middle perforate, be located on the upper surface of the large end step of round nut, is provided with sleeve at the cylindrical of described round nut, circumferentially fixes by pin between cover and the round nut.
