Abstract
The utility model discloses a three-jaw fixture, comprising a cylindrical jacket and three jaws, wherein a propping device is arranged in the cylindrical jacket, the three jaws are arranged on the top end of the cylindrical jacket in a sliding manner and arranged in an annular array, and the top of the propping device is positioned at the center of the annular array formed by the three jaws. According to the three-jaw fixture, the three jaws can be uniformly propped open with a cone top through propping forwards to fix a workpiece, so that the workpiece is subjected to uniform stress in all directions and prevented from deforming.
Description
Technical field
The utility model relates to industrial technology field, relates in particular to a kind of Three-jaw fixture.
Background technology
In industrial processes, often can need to need to be processed by annular workpiece or tubular to be fixed; in most situation, be to be all fixed by Three-jaw fixture; each jaw is the dynamics that regulates clamping by screw rod; but because each jaw regulates respectively; so be difficult to make the clamping degree of three jaws to keep unified; this just causes the discontinuity of workpiece in each direction, is easy to produce deformation.
Utility model content
in order to solve existing the problems referred to above, the utility model provides a kind of Three-jaw fixture, can in gripping workpiece, make workpiece uniform stressed can not produce deformation.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of Three-jaw fixture, it is characterized in that: comprise tubular chuck, three jaws, the inside of described tubular chuck is provided with ejection device, what three jaws slided is arranged on tubular chuck top, three jaws arrange in the top of tubular chuck circular array, and the top of described upper ejection device is positioned at the center of the annular array that three jaws form.
Preferably, described upper ejection device comprises top stem casing and push rod, top cover is fixed on by locating piece on the madial wall of tubular chuck, the inner side of top stem casing is provided with mutual corresponding screw thread with the outside of push rod, the top of push rod is provided with cone shape top, the axle center of described cone top and the axis coinciding of tubular chuck.
Preferably, described jaw comprises strut and arc jacking, and strut is arranged on tubular chuck top, and arc jacking is arranged on the head of strut, and the afterbody of strut is also provided with ball, and the afterbody of strut points to the axle center of tubular chuck.
Preferably, the top of described tubular cartridge clip is also provided with three positioning tables, and positioning table entangles the strut of jaw.
Preferably, the tail end of described push rod is also provided with rotating disk.
The beneficial effect that the utility model reaches is: the sinciput coming directly towards by cone can make three jaws outwards strut workpiece is fixed uniformly, and workpiece is uniform stressed in all directions, can not produce deformation.
Brief description of the drawings
Fig. 1 is lateral section of the present utility model structural representation;
Fig. 2 is top view of the present utility model.
Detailed description of the invention
In order to further describe technical characterstic of the present utility model and effect, below in conjunction with the drawings and specific embodiments, the utility model is described further.
See figures.1.and.2, a kind of Three-jaw fixture, the inside that comprises tubular chuck 1, three jaws 2, described tubular chuck 1 is provided with ejection device 3, what three jaws 2 slided is arranged on tubular chuck 1 top, three jaws 2 arrange in the top of tubular chuck 1 circular array, and the top of described upper ejection device 3 is positioned at the center of the annular array that three jaws 2 form.
Further, described upper ejection device 3 comprises top stem casing 31 and push rod 32, top stem casing 31 is fixed on by locating piece 33 on the madial wall of tubular chuck 1, the inner side of top stem casing 31 is provided with mutual corresponding screw thread with the outside of push rod 32, the top of push rod 32 is provided with cone shape top 34, the axle center of described cone top 34 and the axis coinciding of tubular chuck 1.
Further, described jaw 2 comprises strut 21 and arc jacking 22, and strut 21 is arranged on tubular chuck 1 top, and arc jacking 22 is arranged on the head of strut 21, and the afterbody of strut 21 is also provided with ball 23, and the afterbody of strut 21 points to the axle center of tubular chuck 1.
Further, the top of described tubular chuck 1 is also provided with three positioning tables 4, and each positioning table 4 entangles the strut of a jaw 2.
In order to facilitate the propelling of push rod 32, the tail end of described push rod 32 is also provided with rotating disk 5.
When use, rotating by crank the rotating disk 5 that is located at push rod 32 afterbodys drives push rod 32 to rotate, because the inner side of top stem casing 31 is provided with mutual corresponding screw thread with the outside of push rod 32, after rotating, push rod 32 slowly drive cone shape top 34 to sinciput, pass through, top 34 outwards struts with the uniform strut 21 of contacting of strut 21 afterbody balls 23, and three jackings 22 prop up annular workpieces fixing simultaneously.
Above-described embodiment does not limit the utility model in any form, and all technical schemes of taking the form that is equal to replacement or equivalent transformation to obtain, within all dropping on protection domain of the present utility model.
