Abstract
The invention discloses a self-centering device for a thin-walled part. The self-centering device for the thin-walled part comprises a clamp body, wherein one end of the clamp body is of a truncated-cone-shaped structure; the radius of the clamp body is reduced sequentially from the middle part to the end part; a expansion sleeve is sleeved on the clamp body movably; a screw rod penetrates the expansion sleeve and is in threaded connection with the clamp body; a pressing block for jacking the expansion sleeve is arranged at the end part of the screw rod; and a return ring is arranged between the expansion sleeve and the clamp body and sleeved on the screw rod. The self-centering device for the thin-walled part is simple in structure and easy to implement. The screw rod moves left and right to drive the expansion sleeve to move left and right, and then the thin-walled part is assembled and disassembled. The self-centering device is convenient and simple to operate, and can effectively prevent deformation of the thin-walled part.
Description
Technical field
The present invention relates to a kind of thin-walled parts self-centering device.
Background technology
In the mechanical processing process of part, adopt chuck to part centering and clamping usually, yet, need the thin-walled parts of processing excircles and endoporus for some, because its wall is thinner, with the words of chuck clamping, not only clamping inconvenience, complex operation, and easily make thin-walled parts be out of shape.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of thin-walled parts self-centering device is provided, adopt chuck clamping thin-walled parts complex operation, clamping inconvenience, and the problem that easily makes the thin-walled parts distortion to solve.
The objective of the invention is to be achieved through the following technical solutions:
A kind of thin-walled parts self-centering device, comprise clamp body, one end of described clamp body is the truncated cone-shaped structure, its radius is successively decreased successively by centre to end, and movably be arranged with the swelling cover on it, screw rod passes the swelling cover and is threaded with clamp body, and the end of screw rod is provided with the briquetting for roof pressure swelling cover, be provided with the backhaul circle between described swelling cover and the clamp body, described backhaul snare is located on the screw rod.
Further, the other end of described clamp body has installing hole, is convenient to install.
Further, be provided with cushion block between described briquetting and the swelling cover, be provided with cushion block between described swelling cover and the backhaul circle.
Further, described briquetting and screw rod are structure as a whole.
Beneficial effect of the present invention is that described thin-walled parts self-centering apparatus structure is simple, is easy to realize, it drives swelling cover move left and right by the move left and right of screw rod, thereby realizes the loading and unloading to thin-walled parts, convenient and simple for operation, and can effectively prevent the thin-walled parts distortion.
Description of drawings
Fig. 1 is the structural representation of thin-walled parts self-centering device of the present invention.
Among the figure:
1, installing hole; 2, clamp body; 3, workpiece; 4, swelling cover; 5, cushion block; 6, pressing plate; 7, backhaul circle; 8, screw rod.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to shown in Figure 1ly, Fig. 1 is the structural representation of thin-walled parts self-centering device of the present invention; In present embodiment, a kind of thin-walled parts self-centering device, comprise clamp body 2, the right-hand member of described clamp body 2 is the truncated cone-shaped structure, its radius is successively decreased successively by centre to end, and movably be arranged with swelling cover 4 on it, the left end of clamp body 2 has installing hole 1, screw rod 8 passes swelling cover 4 and is threaded with clamp body 2, and the right-hand member end of screw rod 8 is provided with the briquetting 6 for roof pressure swelling cover 4, and described briquetting 6 and screw rod 8 are structure as a whole, and be provided with cushion block 5 between briquetting 6 and the swelling cover 4, be provided with backhaul circle 7 between described swelling cover 4 and the clamp body 2, described backhaul circle 7 is set on the screw rod 8, and is provided with cushion block 5 between backhaul circle 7 and the swelling cover 4.
During use, workpiece 3 is set in outside the swelling cover 4, by tightening screw rod 8, make screw rod 8 move to left end, pressing plate 6 on the screw rod 8 promotes swelling cover 4 and slides left on clamp body 2, because clamp body 2 right-hand members are the truncated cone-shaped structure, its radius is successively decreased successively by centre to end, swelling cover 4 distending in the moving process on clamp body 2, thereby clamping work pieces 3; When need dismounting workpiece 3, only need unscrew screw rod 8, make screw rod 8 move right, the backhaul circle 7 on the screw rod 8 promotes swelling cover 4 and slides to the right on clamp body 2, thereby unclamps workpiece 3; The present invention is simple in structure, and workpiece 3 is easy to loading and unloading, can realize a clamping of workpiece 3, and can process cylindrical and the endoporus of workpiece 3 simultaneously, and workpiece 3 can be felt relieved fast and can be prevented workpiece 3 distortion.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
