Description
Technical field
The present invention relates to a kind of linear guide pairs.
Background technique
Along with the development of Modern Manufacturing Technology, make traditional manufacturing industry there occurs huge change, Numeric Control Technology, electromechanical integration and industrial robot obtain aborning and apply more widely.Simultaneously the positioning precision of mechanical transmission mechanism, guiding accuracy and feed speed are improving constantly, and make traditional guide mechanism there occurs great change.Since starting commercialization from 1973, linear rolling guide, with its exclusive characteristic, instead of traditional sliding straight guide rail gradually, is widely used in the industrial production.Adapt to the mechanical requirement for highi degree of accuracy, high speed, energy saving and shortening product development cycle now, be widely used in the machinery of various heavy Combined machining lathe, numerical control machine tool, highi degree of accuracy electrodischarge cutting machine, grinding machine, industrial robot and even general industry.At present, the external manufacturer producing linear rolling guide mainly concentrates on the U.S., Britain, Germany and Japan and other countries.The domestic manufacture view at linear rolling guide is also in the starting stage.
In the prior art, manufacture in the assembly process of linear guide pairs, putting into, taking out replacing of ball is a difficult problem always, when particularly debugging the frictional force of slide block, needs to change according to the situation of frictional force between ball and slide rail the ball more mated; Be, after reverser is taken off, then open reverser in prior art, load or take out ball; Or ball is filled in from the gap of retainer and slide block inner track; This mode wastes time and energy, and efficiency of assembling is low.
So the mode of the loading ball of prior art brings inconvenience to assembling and debugging efforts.
Summary of the invention
The technical problem that the present invention first will solve is to provide a kind of linear guide pairs being suitable for convenient loading or taking out ball.
