Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0016] See attached figure 1 As shown in -3, a push-type self-centering jaw of this embodiment includes a mounting plate, a box body 2, a movable block 3, and m jaws 4, wherein m is a natural number > 2, and in this embodiment m uses 3.

[0017] The box body 2 is a tubular member, and the installation plate is fixed on the top of the box body 2. The installation plate is formed with three installation cavities 5. The installation plate is composed of three plate-like parts 1, and the plate-like parts 1 are fixed on the top of the box body 2. Each phase There is a certain gap between two adjacent plate-shaped parts 1 to form an installation cavit...

Abstract

The invention discloses a push-type self-centering clamping jaw. The push-type self-centering clamping jaw comprises a mounting plate, a box body, a movable block and m clamping jaw bodies, wherein the m is a natural number greater than 2; the mounting plate is fixed to the top of the box body which is in a tubular shape, and the mounting plate is provided with m mounting cavities; the movable block is arranged in the box body and moves up and down under the drive of an air cylinder, the movable block is provided with m branch plates, each branch plate can be embedded into the corresponding mounting cavity, and each branch plate is provided with an inclined plane; the clamping jaw bodies are rotatably installed in the mounting cavities through fix shafts, the clamping jaw bodies are inclined in the same direction as the inclined planes, the heads at the upper ends of the m clamping jaw bodies are close to each other and the tails at the lower ends of the m clamping jaw bodies are awayfrom each other, and the m inclined planes can move up and act on the tails of the clamping jaw bodies to rotate around the fixed shafts, the lower ends of the clamping jaw bodies are provided with strip-shaped holes, and the strip-shaped holes of the clamping jaw bodies are rotatably connected to the inner sides of the lower ends of the branch plates through connecting rods. The push-type self-centering clamping jaw is suitable for workpieces with large dead weight.

Description

technical field [0001] The invention relates to a fixture for clamping pipe workpieces, in particular to a push-type self-centering jaw. Background technique [0002] In the process of manufacturing and processing, the centering and clamping of tubular workpieces has always been a common problem. In existing common automatic pipe fixtures, hydraulic three-jaw chucks or pneumatic grippers are generally used to centrally position and clamp the workpiece. Due to the development of the manufacturing industry towards high precision and high automation, hydraulic three-jaw chucks or pneumatic grippers have their own limitations. The accuracy of hydraulic three-jaw chucks is not high and oil circuits are required, while pneumatic grippers are The clamping force is small, and there is a certain requirement for the self-weight of the workpiece. It cannot adapt to the development of the current manufacturing industry, its accuracy is not high, the clamping force is not large, and it...
