Abstract
The invention discloses a biconical expansion locking mechanism, which comprises a bearing seat, a rotation shaft, a biconical expansion chuck, a large pull rod, a pull pin, a floating joint, a bearing and a spring, wherein the rotation shaft is arranged inside the bearing seat; the large pull rod is arranged inside the rotation shaft; the lower end of the bearing seat adopts a bearing down pressing cap for being pressed; the spring is arranged between the bearing down pressing cap and a spring push pull head, and the spring surrounds the outer part of the rotation shaft; and the biconical expansion chuck comprises a positioning core shaft, an expansion sleeve, a bushing and a small pull rod. The device has a simple structure, the design is reasonable, the size is small, the weight is light, and transportation and storage are facilitated; a pure mechanical structure is adopted, the use stability is good, detachability is good, and mounting and replacement are facilitated; through matching between the expansion sleeve, the rotation shaft, the small pull rod and the positioning core shaft, the rotation shaft only needs to be pulled to firmly fasten an article, the article is driven to rotate, the operation is simple and convenient, the use effects are good, the biconical expansion locking mechanism is applicable to motors of various types, the application range is wide, and the service life is long.
Description
technical field [0001] The invention relates to a locking mechanism, in particular to a double-cone expansion locking mechanism. Background technique [0002] The motor, commonly known as the motor, refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. According to the type of working power supply, motors can be divided into DC motors and AC motors, DC motors can be divided into brushless DC motors and brushed DC motors, and AC motors can be divided into single-phase motors and three-phase motors. According to the structure and working principle, motors can be divided into DC motors, asynchronous motors and synchronous motors. With the acceleration of my country's industrialization process, the motor industry is developing vigorously thereupon, but the locking structu...
