Abstract
The utility model discloses a gear shaving clamping apparatus, which comprises a central shaft. The central shaft is a step shaft consisting of a big cylinder and a small cylinder. Both ends of the central shaft are provided with taper holes. The length of the small cylinder of the central shaft is longer than the width of the work piece. The taper holes on the both ends of the central shaft are communicated with each other through a center hole arranged in the center of the central shaft. The big cylinder of the central shaft is provided with a groove. The groove is at least uniformly provided with three through holes. Elongated slots are respectively arranged between each through hole and the external end surface of the small cylinder of the central shaft. The utility model not only hassimple structure, but also has convenient operation.
Description
Technical field
The utility model relates to a kind of anchor clamps that add work gear, especially a kind of Fixture for Gear-shaving.
Background technology
Existing a kind of Fixture for Gear-shaving; it comprises axle, shaving is top and axle sleeve; axle be fixed in lathe two top between; shaving is top goes up at least one elastic parts of suit, be surrounded on the outer protective sleeve of elastic parts; elastic parts one end leans the seating surface of shaving on top; an other end is an axle sleeve, the top limited impression that is provided with for the axle sleeve axial slip of shaving, and axle sleeve is provided with the screw that stretches into limited impression.Axle center symmetry has groove.Elastic parts is the disk spring that is distributed on the top seating surface of shaving.The course of work of above-mentioned anchor clamps is: 1. the shaving that configuration can be general on lathe is top, the butterfly spring of on shaving is top, packing into, and spring protection cover, and the axle sleeve of then packing into, and with screw it is fixed in the top groove to slide.2. the workpiece to be processed of on axle, packing into.3. it is top axle to be loaded onto lathe, top on the top, compresses end face by spring is auxiliary, and workpiece end face and axle sleeve end face are adjacent to, and the another side of workpiece and axle step end face are adjacent to.Top stretching out makes the axle spreading, fits tightly with the workpiece to be processed endoporus.4. startup machine tooling.Completion of processing is backed out toply, makes axle internal expanding withdrawal, and spring relaxation can take off axle.Because the part that axle installs workpiece equates with the width of workpiece, the therefore top axle radial load that an end produced when interior of slotting that reaches is big inadequately, and workpiece axially movable phenomenon on axle takes place easily.For solving this phenomenon, above-mentioned anchor clamps have increased the auxiliary hold-down mechanism of end face elasticity, but not only make the structure of anchor clamps become complicated like this, and operating personnel's operation is also more loaded down with trivial details in the process, operates very inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of Fixture for Gear-shaving, and it is not only simple in structure, and easy to operate.
For solving the problems of the technologies described above, a kind of Fixture for Gear-shaving of the utility model, it contains axle, this axle is the step axle that large cylinder and small cylinder constitute, the two ends of axle are provided with taper hole, the length of described axle small cylinder is longer than the width of workpiece, the centre bore phase communications and liaison that the taper hole that described axle two ends are provided with is provided with by the centre, the large cylinder of described axle is provided with groove, on this groove, be laid with three through holes at least, between the outer face of each through hole and axle small cylinder, be respectively equipped with elongated slot.
The outer surface of the small cylinder of described axle is provided with anti-slip tank.
Because the length of the small cylinder of axle is longer than the width of workpiece, it is the arm of force that the arm of force is longer than prior art, therefore reach axle and slot in the end and when pressing closer this end when lathe is top, thereby the radial load that is produced makes big than prior art of the frictional force that produces between the small cylinder of workpiece and axle than prior art big, so workpiece can not endwisely slip; Thereby the axial force that is produced also fits tightly the end face of workpiece and the end face of large cylinder than the big of prior art, so workpiece can accurate positioning and good stability.Since at the elongated slot that is provided with on the axle between the outer face of the through hole of axle and small cylinder, this is longer than the length of prior art groove greatly, therefore the small cylinder of axle is relatively good in elasticity radially, so not only make operating personnel easy to operate, and make when lathe is top to press closer this end and only to need less strength, just can realize that accurate work piece positioning stablizes and do not slide.The utility model has saved the auxiliary hold-down mechanism of end face elasticity of prior art, and this not only makes the structure of anchor clamps become simply, and has made things convenient for operating personnel's operation.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
1. taper holes among the figure, 2. large cylinder, 3. groove, 4. through hole, 5. anti-slip tank, 6. taper hole, 7. small cylinder, 8. elongated slot, 9. centre bore, 10. workpiece.
The specific embodiment
Among Fig. 1, a kind of Fixture for Gear-shaving of the utility model, it contains axle, and this axle is the step axle that large cylinder 2 and small cylinder 7 constitute.The two ends of axle are respectively equipped with taper hole 1 and taper hole 6.The length of axle small cylinder 7 is longer than the width of workpiece 10.The centre bore 9 that the taper hole 1 that the axle two ends are respectively equipped with and taper hole 6 are provided with by the centre is communications and liaison mutually.The large cylinder 2 of axle is provided with groove 3, is laid with three through holes 4 on this groove 3 at least, is provided with elongated slot 8 between the outer face of each through hole 4 and axle small cylinder 7.In the present embodiment, as shown in Figures 2 and 3, on this groove 3, be laid with four through holes 4, be provided with four elongated slots 8 between the outer face of each through hole 4 and axle small cylinder 7.For further preventing workpiece 10 endwisely slipping on axle small cylinder 7, on the outer surface of the small cylinder 7 of axle, be provided with anti-slip tank 5.Use the utility model that workpiece 10 is added man-hour, at first workpiece 10 is sleeved on the small cylinder 7 of axle, the end face of the large cylinder 2 of the end face of workpiece 10 and axle is steadily fitted.Again in the two top taper holes 1 and taper hole 6 that withstand on the axle two ends respectively with lathe, the two top axles that hold out against make its small cylinder 7 at spreading radially, and its result fits tightly the end face of the large cylinder 2 of workpiece 10 and axle, makes the frictional force of generation between workpiece 10 and the axle small cylinder 7 prevent slip between workpiece 10 and the small cylinder 7 in the power that radially produces in the power that axially produces.Start lathe and process, completion of processing withdraws from top from axle two taper holes 1 and 6, axle small cylinder 7 is under self elastic force effect, return to reset condition, workpiece 10 takes out from axle small cylinder 7, loads onto a unprocessed workpiece again and processes.The utility model has compared with prior art saved the auxiliary hold-down mechanism of end face elasticity, and so not only structure becomes very simple, and also makes operating personnel's operation become convenient because of simple in structure.
