Abstract
The invention provides a stirring frictional connection keyless eye mixing head. The mixing head is characterized by being composed of a blank cover with a gripping handle, a large cylinder, a small cylinder, a stirring pin, a stirring pin handle, a micro motor, a signal receiver / transmitter and a screw bolt; the gripping handle on the blank cover is connected with the blank cover; the blank cover is connected with one end of the large cylinder; the small cylinder is arranged on the other end surface of the large cylinder, screw threads are arranged on an inwall vehicle of the small cylinder, one end of the small cylinder extends out of the large cylinder, the surface of the outer part of the small cylinder extending out of the large cylinder and the upper part of the stirring pin form a shaft shoulder of a mixing head, the stirring pin and the stirring pin handle are integrally formed, and screw threads are arranged on an excircle vehicle of the stirring pin handle in order to cooperate with the screw threads of the inner wall of the small cylinder; one end of the stirring pin handle located inside the large cylinder is connected with the micro motor, and the signal receiver / transmitter is arranged on the micro motor. The mixing head is simple in structure, the assembly and the maintenance are convenient, the stirring frictional connection of keyless eye defect is achieved, and the quality of appearance of the stirring frictional connection of a board material is increased.
Description
technical field [0001] The invention relates to a friction stir joining technology, in particular to a stirring head for friction stir joining, in particular to a keyless stirring head for friction stir joining, which is mainly used to realize stirring and squeezing in the process of friction stir joining of plates. It is formed by pressing, specifically a special stirring head for friction stir connection without a keyhole hole. Background technique [0002] Friction stir joining technology is a relatively advanced technology in the current connection technology. Part of the development of friction stir joining technology mainly depends on the development of stirring head design technology. The most widely used stirring head in the market is the non-shrinking stirring head, that is, in the friction stir joining After the end, the defect of the keyhole hole is left, which often cannot meet the requirements of some users. For example, the friction stir connection of the whee...
