Description
Technical field
The utility model relates to mechanical processing technique field, is specifically related to a kind of transmission shaft clamping device.
Background technology
Transmission shaft is the rotator of a high rotating speed, few supporting, is made up of central siphon, telescopic and universal joint. Transmission shaft connects or assembles every accessory, and circular object accessory that is removable or that rotate, and the alloy steel pipe generally all using light and antitorque property good is made. Being the axle rotation of variator being passed to main reduction gear concerning the car of preposition engine rear wheel drive, it can be that several joint is connected by universal joint. It is the rotator of a high rotating speed, few supporting, and therefore its transient equilibrium is most important. General transmission shaft all to be carried out dynamicbalance test before dispatching from the factory, and has adjusted on equilibrator.
In existing transmission shaft complete processing, thread jaw chuck is usually adopted to be clamped on lathe by transmission shaft to process, and the thread jaw chuck adopted is made up of chuck body, movable claw and claw driving mechanism. On thread jaw chuck below three claw targeting parts, screw thread is had to be meshed with the flat thread at the dish conical gear back side, when transmission shaft is clamped by needs time, when rotating conical pinion with spanner by four square holes, dish gear rotates, and the flat thread at the back side drives three claws close or exit to center simultaneously, in order to clamp the workpiece of different diameter, complex structure, and the time completing whole clamping operation is long.
Practical novel content
The thread jaw chuck complex structure that the utility model adopts to be gripped by transmission shaft to solve in existing technique and the problem to the time length completing whole clamping operation, the purpose of this utility model is to provide a kind of simple fixture for transmission shaft of structure.
The utility model offer base case is: transmission shaft clamping device, comprise chuck and clamping device, wherein, described chuck is provided with threaded hole, and described threaded hole is connected with the groove hole placing transmission shaft, described groove hole is tapered, described clamping device comprises baffle plate, threaded rod, tapered clamp pawl, and described baffle plate is fixedly connected with described threaded rod, and described threaded rod is meshed with described threaded hole, described threaded rod connects described tapered clamp pawl, and wedge shape face and the described groove hole of described tapered clamp pawl adapt.
The principle of work of base case: chuck is provided with threaded hole, threaded hole internal thread is connected with threaded rod, butterfly, move under threaded rod, move under tapered clamp pawl, after moving under tapered clamp pawl, now gap occur between tapered clamp pawl and groove hole, tapered clamp pawl is in lax state, after insertion transmission shaft, reverse rotation baffle plate, threaded rod spiral, drives tapered clamp pawl to rise, and groove hole contacts gradually with tapered clamp pawl and tapered clamp pawl is applied pressure, compress tapered clamp pawl, so that transmission shaft is clamped by tapered clamp pawl; After machining, butterfly, moves under threaded rod, and tapered clamp pawl is in lax state again, can take out transmission shaft.
The useful effect of base case is: compare in existing technique the thread jaw chuck adopted, make threaded rod lower shifting or rising in threaded hole by butterfly, change the lax of tapered clamp pawl or clamped condition, thus complete unclamping or clamp position transmission shaft, structure is simple, easy and simple to handle.
Preferred version one: based on scheme preferred, the side of described baffle plate is provided with recessed hole; Useful effect: after arranging recessed hole on the side of baffle plate, is convenient to the clamping to baffle plate so that the rotation of baffle plate is lighter.
Preferred version two: based on scheme again one preferably, the clamping face of described tapered clamp pawl is provided with rubber layer; Useful effect: after rubber layer is set, rubber layer is between tapered clamp pawl and transmission shaft, it is possible to prevent to clamp rear tapered clamp pawl to the abrasion on transmission shaft surface, have again, due to the elasticity of rubber self, when occurring loosening to the clamping of transmission shaft when rubber layer elastic force scope inner conical folder pawl, due to the elastic force of rubber layer, still can ensure that tapered clamp pawl is to the clamped condition of transmission shaft.
Preferred version three: based on scheme again one preferably, described groove hole is provided with polishing layer; Useful effect: by arranging polishing layer so that the surface in groove hole is more smooth, so that tapered clamp pawl and groove hole occur friction when sliding to reduce, thus decreases the abrasion to taper jaw surfaces.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the utility model moving axis clamping device embodiment;
Fig. 2 is the vertical view of baffle plate;
Fig. 3 is the side-view of Fig. 2;
Reference numeral: chuck 100, groove hole 107, baffle plate 201, threaded rod 203, tapered clamp pawl 205, recessed hole 211, rubber layer 215, transmission shaft 300.
Embodiment
By reference to the accompanying drawings 1, transmission shaft clamping device shown in Fig. 2 and Fig. 3, comprise chuck 100 and clamping device, chuck 100 is provided with threaded hole, threaded hole is connected with the groove hole 107 placing transmission shaft, groove hole 107 is tapered, clamping device comprises baffle plate 201, threaded rod 203, tapered clamp pawl 205, the side of baffle plate 201 as shown in Figures 2 and 3 is provided with recessed hole 211, baffle plate 201 is fixedly connected with threaded rod 203, threaded rod 203 is meshed with threaded hole, threaded rod 203 connects tapered clamp pawl 205, wedge shape face and the groove hole 107 of tapered clamp pawl 205 adapt, the clamping face of tapered clamp pawl 205 is provided with rubber layer 215.
