A locking device for random position locking and its minimum force determination method

Abstract

The invention relates to a locking device for random position locking and a method for determining the minimum stress thereof, belonging to the technical field of locking devices. A locking mechanism with simple structure and reasonable design, which realizes locking in random positions by means of eccentric wheels to drive resilient strips and unlocking timely and realizes cycle working with reliable locking, and a method for determining the minimum stress thereof are provided. The technical scheme comprises a fixed hollow locking body and a piston which is slidingly installed inside the hollow locking body, and a moving body which is installed on a piston rod in a sleeved mode; the piston is provided with resilient strips and eccentric wheels for driving the resilient strips; each resilient strip is provided with a wedge block which is installed between the resilient strip and the inner wall of the hollow locking body; the resilient strips are jacked up on the wedge blocks by the rotating eccentric wheels; The locking device is widely used in locking mechanism involved in complex motion.

Description

technical field [0001] The invention relates to a locking device for random position locking and a method for determining the minimum force thereof, belonging to the technical field of locking devices. Background technique [0002] With the development of science and technology, innovation and development are constantly being carried out in various fields, pursuing the development concept of high efficiency, speed, simplicity and environmental protection. Innovative developments are everywhere, locking devices in mechanical structures are a good example. Locking devices are widely used in various mechanical structures, such as aerospace, mining machinery, construction machinery, vehicle engineering and other fields. However, most locking devices can only be locked in a single movement mode at a fixed position at present, such as sleeve locking, snap ring locking, internal expansion locking, cone-disc spring locking and other mechanisms. Although the locking device at any p...

Problems solved by technology

Electromagnetic locking is designed using electromagnetic principles. Although it is energy-saving, environmentally friendly, easy to install, and convenient to use, its time response control of magnetic force cannot meet the requirements of milliseconds; although hydraulic locking can be locked and unlocked in a short time, However, the hydraulic oil is easily invaded by pollutants and dust, and the reliability cannot be guaranteed. The temperature change of the hydraulic oil will also affect its accuracy. The layout of various oil circuits makes it much more complicated than the purely mechanical locking mechanism. High cost
