Automatic locking mechanism for tooth-shaped revolving shaft

Abstract

The invention discloses an automatic locking mechanism for a tooth-shaped revolving shaft. The automatic locking mechanism for the tooth-shaped revolving shaft comprises a revolving shaft; a tooth-shaped shaft is arranged on the revolving shaft in a coaxial line mode; a locking plate is provided with locking teeth which are matched with teeth of the tooth-shaped shaft; a locking plate head is connected on a supporting frame of the revolving shaft in a hinged mode; a control handle of the locking plate is connected to a locking control mechanism; the locking teeth and shaft teeth of the tooth-shaped shaft are correspondingly arranged according to meshing relationships; the locking control mechanism comprises a fixing seat which is arranged on the upper portion of the control handle of the locking plate; one end of a spring is fixed in a spring installation hole of the fixing seat; the other end of the spring is connected with the control handle; a linear motor is arranged on the lower portion of the control handle; an output end of the linear motor aligns to the lower portion of the control handle; and adjusting screws and locking nuts are arranged at the bottom of the spring installation hole of the fixing seat. A reference diameter of the tooth-shaped shaft is 60 mm and the number of the teeth is 24. The locking teeth of the locking plate are trapezoid-shaped teeth, the number of the teeth is 3, and other parameters are matched with shaft tooth parameters of the tooth-shaped shaft.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a toothed rotary automatic locking mechanism, which is used for locking the rotating shaft of automatic rotary equipment. Background technique [0002] In many automatic rotary devices such as automatic turntables, automatic leveling mechanisms or automatic rotation measuring instruments produced in China, whether it is indoor equipment or vehicle-mounted equipment, the rotating shaft must be automatically locked during testing or use to meet the requirements of the working process. The need for automated processes. [0003] At present, the more commonly used shaft locking methods in China include the shaft-holding type, the latch type, the electromagnetic clutch locking type and the end-toothed disc type. These methods have certain advantages and disadvantages in the process of use, such as the shaft-holding type locking, which mainly uses the structural principle of the br...
