Problems solved by technology

[0002] The currently used tap holders are easy to move, especially when the coolant is used for internal cooling, resulting in quality accidents and abnormal damage to the tap. Broken and the chuck is scrapped; for the occasions where multiple products are produced in turn and different taps need to be replaced, in order to achieve quick changeover, the usual practice is to use one of the models as a benchmark to select standard chucks or taps, and other models use Non-standard taps or non-standard collets, the cost is high, due to the long preparation period of non-standard products, it is not conducive to production preparation

Abstract

The invention discloses a safe breaking-preventing screw tap chuck which comprises a chuck body and further comprises a screw tap sleeve, a supporting arm and a telescopic tightening screw. A tap sleeve fixing groove is formed in a middle shaft of the front portion of the chuck body. A longitudinal tightening thread hole is formed in the upper side wall and the lower side wall of the tap sleeve fixing groove. The telescopic tightening screw comprises a screw body. The screw tap sleeve is provided with a screw tap fixing groove. The screw tap sleeve is distributed in the tap sleeve fixing groove and tightened and fixed through the telescopic tightening screw by means of the tightening thread hole. The supporting arm comprises a supporting arm body which is approximately shaped like the Arabic number seven and distributed on the left side and the right side of the front portion of the chuck body. The left lower end of the supporting arm body makes contact with a handle portion of a screwtap in an extruding manner. The safe breaking-preventing screw tap chuck has a good effect of fastening the screw tap, the screw tap is replaced conveniently, and breaking of the screw tap is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of metal cutting devices, in particular to a safety anti-break tap chuck. Background technique [0002] The currently used tap holders are easy to move, especially when the coolant is used for internal cooling, resulting in quality accidents and abnormal damage to the tap. Broken and the chuck is scrapped; for the occasions where multiple products are produced in turn and different taps need to be replaced, in order to achieve quick changeover, the usual practice is to use one of the models as a benchmark to select standard chucks or taps, and other models use The cost of non-standard taps or non-standard chucks is relatively high. Due to the long preparation period of non-standard products, it is not conducive to production preparation. [0003] The disclosure of the above background technical content is only used to assist in understanding the concept and technical solution of the present invention, and i...
