Abstract
The invention discloses a spring chuck with a belleville spring and aims at solving the problem that shaft workpieces are inconvenient to clamp in the prior art. The spring chuck with the belleville spring comprises a hollow clamp body and a collet chuck provided with an open groove, wherein the open groove axially extend to the middle of the collet chuck from the head portion of the collet chuck, the collet chuck is matched with a cavity of the clamp body, and an inner conical surface for compressing the collet chuck is arranged at the end portion of the clamp body. The spring chuck further comprises a nut in threaded connection with the clamp body, a screw moving along the cavity of the clamp body, the belleville spring connected with the screw and the clamp body and a lever, wherein one end of lever is in contact with the nut, the other end of the lever is connected with the screw and the collet chuck, a supporting point of the lever is arranged on the clamp body, and an elastic rubber layer is filled in the open groove of the collet chuck. The spring chuck is simple in structure and easy to operate.
Description
Technical field
The present invention relates to the clamping device technical field of Machining of Shaft-type Parts, be specifically related to a kind of collet with disk spring.
Background technology
When machine tool chief axis working shaft-like part, need the clamping device of axle class special use to its clamping position, at present, often there is following problem in the clamping device that the manufacturing procedure of shaft-like workpiece adopts: in the time of need to carrying out process operation along circumferential a plurality of angles to shaft-like workpiece, because clamping device can not regulate clamping angle, or the structure of adjusting angle is more complicated, makes troubles to operation, reduce working (machining) efficiency.
Summary of the invention
The invention is intended to provide a kind of collet with disk spring, to solve the problem of prior art axis class clamping workpiece inconvenience.
For addressing the above problem, the collet with disk spring in this programme, the clamp and the collet chuck that is provided with open slot that comprise hollow, open slot extends axially to collet chuck middle part from collet chuck head, collet chuck mates with clamp cavity, clamp end is provided with for compressing the inner conical surface of collet chuck, also comprise the nut being threaded with clamp, the screw rod moving along clamp cavity, the disk spring of connecting screw rod and clamp, one end can contact with nut, the lever of other end connecting screw rod and collet chuck, in the open slot of collet chuck, is filled with elastic rubber layer.
Compared with prior art, advantage of the present invention is: under duty, during rotating nut, just collide lever and force screw rod upwards to lift, collet chuck is unclamped; When reversion nut upwards moves, disk spring forces collet chuck to move down by spiral shell sweat, clamping work pieces, and the present invention is simple in structure, processing ease, convenient mounting and clamping; In open slot, be filled with elastic rubber layer, no matter collet chuck clamping work pieces whether, open slot is all the time in closed state, and having avoided iron filings to enter collet chuck affects clamping precision.
Further, described collet chuck has inner hexagonal hole, and collet chuck is directly threaded with lever, and bolt links together collet chuck and lever through inner hexagonal hole, makes collet chuck be convenient to change, to adapt to the workpiece of different-diameter.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the collet embodiment of band disk spring of the present invention.
The specific embodiment
Shown in Fig. 1, the collet with disk spring in the embodiment of the present invention, the clamp and the collet chuck 1 that is provided with open slot that comprise hollow, open slot is from collet chuck 1 head shaft to extending to collet chuck 1 middle part, collet chuck 1 mates with clamp cavity, clamp end is provided with for compressing the inner conical surface of collet chuck 1, also comprise the nut 2 being threaded with clamp, the screw rod 4 moving along clamp cavity, the disk spring 5 of connecting screw rod 4 and clamp, one end can contact with nut 2, the lever 3 of other end connecting screw rod 4 and collet chuck 1, in the open slot of collet chuck 1, be filled with elastic rubber layer, described collet chuck 1 has inner hexagonal hole, collet chuck 1 is directly threaded with lever 3, bolt links together collet chuck 1 and lever 3 through inner hexagonal hole.
Under duty, during rotating nut 2, just collide lever 3 and force screw rod 4 upwards to lift, collet chuck 1 is unclamped; When reversion nut 2 upwards moves, disk spring 5 forces collet chuck to move down by spiral shell sweat 4, clamping work pieces.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. the collet with disk spring, the clamp and the collet chuck that is provided with open slot that comprise hollow, open slot extends axially to collet chuck middle part from collet chuck head, collet chuck mates with clamp cavity, clamp end is provided with for compressing the inner conical surface of collet chuck, it is characterized in that, also comprise the nut being threaded with clamp, the screw rod moving along clamp cavity, the disk spring of connecting screw rod and clamp, one end can contact with nut, the lever of other end connecting screw rod and collet chuck, and the fulcrum of lever is located on clamp, in the open slot of collet chuck, is filled with elastic rubber layer.
2. the collet with disk spring according to claim 1, is characterized in that, described collet chuck has inner hexagonal hole, and collet chuck is directly threaded with lever.
