Embodiment Construction

[0042] Examples such as figure 1 , figure 2As shown, an open-type three-jaw self-centering rotary device includes a self-centering chuck part and a self-centering rotary part assembled together. The self-centering chuck part is used to clamp the workpiece, and the self-centering rotary part Drive the workpiece for rotary processing.

[0043] Such as image 3 As shown, the self-centering chuck part is composed of three centering chucks arranged in a triangle, and the three centering chucks are driven by the same power and synchronously linked to realize the self-centering function of the self-centering chuck part of the opening.

[0044] The three centering chucks include a main chuck 1A, a sub-chuck 2 and a sub-chuck 3 that are uniformly distributed at 120 degrees on the same plane; each chuck is provided with a clamping rod 4 .

[0045] The clamping rod 4 and the claw 17 are connected by threads, and changing the clamping rod 4 of different lengths can realize the clampin...

Abstract

The invention discloses an open-type three-jaw self-centering rotation device. The device comprises a self-centering clamping disc portion and a self-centering rotation portion which are assembled together. The self-centering clamping disc portion is used for clamping workpieces. The self-centering rotation portion drives the workpieces to conduct rotation machining. The open-type self-centering clamping disc is adopted, so that the open-type three-jaw self-centering rotation device is particularly suitable for automatic bottoming welding of flanges and connecting pipes with the flanges on the two edges, and the workpieces can be directly lifted away along an opening of the clamping disc after welding is completed. The open-type three-jaw self-centering rotation device is quite suitable for automatic welding, hole forming, cutting and the like of some long circular workpieces, the working mode that long workpieces must be inserted into one end of rotation clamping disc equipment with a central through hole during operation is avoided, the long workpieces can be directly placed on the open-type three-jaw self-centering rotation device from bottom to top by the adoption of the open-type three-jaw self-centering rotation device, unnecessary man-hour waste can be reduced, the working efficiency of the open-type three-jaw self-centering rotation device is improved, and the overall length of the open-type three-jaw self-centering rotation device is decreased.

Description

technical field [0001] The invention relates to a tooling tool used for automatic welding of circular workpieces and flame drilling and blanking, especially for the automatic welding of some long pipe fittings and workpieces with flanges at both ends of the pipe fittings. The utility model relates to a claw self-centering rotary device, which belongs to the technical field of mechanical processing tooling. Background technique [0002] In petroleum, natural gas, chemical and other industries, it is necessary to process round workpieces, such as pipe cutting, drilling, welding, etc. Since there are many types and specifications of the workpieces to be processed, and the sizes are different, it brings a lot of inconvenience to the processing. Generally speaking, simple tools such as roller frames are used to manually cut, open holes, weld, etc. The accuracy of this method cannot be guaranteed, and the quality of the processed workpieces is poor, and the processing efficiency ...
