Vertical and horizontal double guiding device with locking and anti-loosening function

Abstract

The invention provides a vertical and horizontal double-guiding device with a locking anti-loosening function. The vertical and horizontal double-guiding device comprises an installing plate, a dovetail groove guide rail, a male sliding block, a female sliding way and a locking anti-loosening device. The dovetail groove guide rail and the locking anti-loosening device are fixedly connected with the installing plate. The female sliding way can horizontally move along the dovetail groove guide rail. The male sliding block is installed in the female sliding way through cooperation. The male sliding block can move in the female sliding way in the vertical direction. The locking anti-loosening device comprises a locking base, a baffle, a stirring wheel, a pawl, a steel bead, a small spring, a hand wheel, a ratchet wheel shaft, a tower spring and a spring bolt. According to the locking anti-loosening device, the characteristic that a ratchet wheel mechanism formed through cooperation of the ratchet wheel shaft and the pawl can only move in the single direction is utilized, the anti-loosening function is achieved, and loosening prevention is reliable and firm. The vertical and horizontal double-guiding device overcomes the defect of one-way guiding of a traditional linear guide rail, and function that vertical guiding is achieved firstly and then horizontal guiding is achieved can be achieved.

Description

technical field [0001] The invention relates to a vertical and horizontal double guide device with locking and anti-loosening functions. Background technique [0002] Most of the traditional guiding devices include guide rails and sliders. There are pulleys inside the sliders. The sliders are slidably fixed on the guide rails. There are pulleys inside the sliders. As a sliding medium, the linear guide rail has simple structure, low production cost and easy replacement. However, its disadvantages cannot be ignored. The main disadvantage is that the movement direction is single and there is only one degree of freedom. Without a locking device, it is difficult to realize the limit. The friction resistance is large, the wear is fast, the difference between the dynamic and static friction coefficient is large, and the crawling phenomenon is easy to occur at low speed. The gap is difficult to guarantee, too large a gap affects the rotation accuracy, and the gap is too small to ...

Problems solved by technology

However, its disadvantages cannot be ignored. The main disadvantages are: the movement direction is single, and there is only one degree of freedom.

The gap is difficult to guarantee, too large a gap will affect the rotation accuracy, and the gap is too small to increase the friction force, resulting in low mechanical efficiency; therefore, the guide device of the linear guide rail using pulleys as the sliding medium has low service life and low motion accuracy
