Embodiment approach
[0028] As an embodiment of the present invention, the lower part of the connecting sleeve 4 is provided with a gear; the inside of the vertical base 3 and the vertical base 2 31 are provided with a groove of the same size, and the vertical base The groove that offers on one 3 and vertical base two 31 can be combined into a rectangular parallelepiped groove; Described vertical base one 3 and the rectangular parallelepiped groove that vertical base two 31 offer are equipped with worm screw 32; Described worm 32 is meshed with the gear that connects sleeve 4 bottoms;
[0029] During work, when the workpiece needs to be rotated at a certain angle around the vertical direction, the worm screw 32 mounting shaft extending from the vertical base 2 31 is rotated by the tool, and the rotation of the shaft drives the worm screw 32 to rotate, so that the gear and the worm screw 32 are set The meshing connecting sleeve 4 begins to rotate around the vertical direction under the action of th...

The invention relates to the field of clamps, in particular to a turning positioning chuck. The turning positioning chuck includes a base; a power rod is installed on the base; a horizontal rotating shaft is fixedly connected to the power rod; a first vertical base and a second vertical base of a connecting sleeve is fixedly installed on the horizontal rotating shaft; the upper part of the connecting sleeve is fixedly connected with a chuck body, and a flat screw disk and a face gear are installed in the chuck body and a bevel gear is installed on the side of the chuck body; the flat screw disk is in fixed connection with the face gear; the bevel gear and the face gear mesh with each other; guide grooves are opened on the chuck body; jaw bases are slidably installed in the guide grooves; the bottom of each jaw base is provided with flat teeth, which mesh with the teeth on the surface of the flat screw disk; and a jaw body is fixedly installed on each jaw base. The turning positioning chuck has a simple structure and convenient operation, and can adjust the processing angle of the workpiece when the workpiece is in a clamping state; and therefore, the number of re-clamping during the processing of the workpiece is reduced, errors are reduced, and the quality of the workpiece is improved.
Description
technical field [0001] The invention relates to the field of fixtures, in particular to a steering positioning chuck. Background technique [0002] Most of the chucks used in existing mechanical processing are three-jaw chucks and four-jaw chucks; after the chucks hold the workpiece, the processing angle of the workpiece cannot be adjusted. Therefore in the processing technology method of pipe joint tee and similar products, every one in the tee has been processed, the workpiece must be taken off from the machine tool, and then re-clamped on the machine tool to process the other end. The problem existing in the prior art is that the processing angle of the workpiece cannot be adjusted, and when the workpiece needs to be processed with multiple surfaces, multiple clampings lead to large production errors and low production efficiency. Therefore, it is necessary to propose a steering positioning chuck that can reduce the number of times of clamping during workpiece processing...
