Problems solved by technology

[0002] At present, the locking device that prevents the circumferential rotation of the turntable mostly adopts the manual ordinary latch type, and this structure cannot be completed by remote electronic control.
The use of electric latches alone cannot meet the needs of locking the turntable when the power supply is abnormal or when the power is off for debugging, and there is no signal display for locking or unlocking in place, and the turntable cannot predict the locking or unlocking status of the locking and fixing device when turning the direction. , easy to damage parts by misoperation

Embodiment 1

[0048]In this embodiment, the locking device includes a housing, a spring, a latch assembly, an electromagnet, a micro switch, and a dovetail nut. The housing is the installation base of all components, and it is a hollow cylindrical structure. The center of the housing and the upper and lower contact parts of the pin assembly are provided with groove structures for placing sealing rings. An electric socket is installed on the upper surface of the shell, and a raised hollow circular platform structure is arranged on the lower surface, and the middle cavity of the circular platform is used for placing a tapered plug. One end of the plug assembly is a tapered plug, the middle is a mandrel, and the other end is a screw rod. The cylindrical section on the tapered plug is used for guiding, and the inner surface is opened with a guide groove to prevent the free rotation of the tapered plug in the circumferential direction. The tapered angle can realize the turntable Self-locking. T...

Embodiment 2

[0056] In this embodiment, a locking and fixing device with manual and automatic control, which includes a shell and a flange fixedly connected together, a micro switch, an electromagnet, a spring, a latch assembly, a dovetail nut, an electrical socket, and a sealing ring . It is characterized in that: under the condition of electrification, the axial electromagnetic force generated by the electromagnet overcomes the axial pretightening force and contact friction force of the spring, and pulls the head of the bolt assembly out of the base hole to realize the unlocking function. After the electromagnet is powered off, the head of the bolt assembly returns to the base hole under the action of the spring preload to realize locking.

[0057] The pin assembly is composed of a tapered plug, a mandrel and a screw that are fixed together. The lower end of the conical plug is a conical structure, and the conical angle should meet the self-locking requirements of the turntable, and it ...

Abstract

The invention belongs to the technical field of machines, and particularly relates to a locking device integrally controlled manually and automatically. The locking device integrally controlled manually and automatically comprises a shell, an electromagnet, a spring, a screw rod, a dovetail nut, a mandrel and a conical plug. The locking device integrally controlled manually and automatically adopts the electromagnet as an actuating mechanism, a microswitch serves as an in-place trigger signal, and the functions of automatic unlocking, automatic locking and state indication are achieved in theprocess of pulling a plug pin mechanism to conduct linear motion; the manual operation function is achieved by arranging the nut and the screw rod mechanism; by additionally arranging a sealing ring,the locking device has the waterproof sealing function; and a plug pin assembly is contact fit with a base hole by adopting a conical face, the reliability of the locking device is improved, the service life of the locking device is prolonged, and the position alignment error can be automatically corrected.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a locking device with automatic manual control. Background technique [0002] At present, most of the locking devices that prevent the turntable from rotating in the circumferential direction are of the manual ordinary latch type, and this structure cannot be completed by remote electronic control. The use of electric latches alone cannot meet the needs of locking the turntable when the power supply is abnormal or when the power is off for debugging, and there is no signal display for locking or unlocking in place, and the turntable cannot predict the locking or unlocking status of the locking and fixing device when turning the direction. , It is easy to damage parts by misoperation. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a locking device with ...
