The invention discloses an adjustable rectangular guide rail pair device comprising a rectangular guide rail, wherein a sliding block is movably sleeved on the rectangular guide rail; a pin roller contacted with the guide rail is arranged on the inner side of the sliding block; the sliding block is formed by enclosing a base plate, a top plate, a left side plate and a right side plate; a front upper pin roller and a rear upper pin roller which are horizontally arranged are adjustably arranged on the inner sides at the front end and the rear end of the upper part of the sliding block; a front lower pin roller and a rear lower pin roller which are horizontally arranged are fixedly arranged on the inner sides at two ends of the lower part of the sliding block; a front left pin roller and a rear left pin roller which are vertically arranged are adjustably arranged at the front end and the rear end on the left side of the middle of the sliding block; and a front right pin roller and a rearright pin roller which are vertically arranged are fixedly arranged at the front end and the rear end on the right side of the middle of the sliding block. With the design, the size of the guide railcan be adjusted in time according to the size of the guide rail and the positioning precision and the driving stability of a guide rail pair can be effectively ensured, thereby meeting high-precisionrequirement on the guide rail during use.
Description
technical field [0001] The invention relates to a guide rail auxiliary device, in particular to an adjustable rectangular guide rail auxiliary device. Background technique [0002] At present, as a rectangular linear guide pair used in various machinery and semiconductor equipment, it is widely used because of its simple structure, small dynamic and static friction coefficient, good rigidity, large bearing capacity, high positioning accuracy, and stable transmission. However, at present, the slider part of the general rectangular linear guide pair can only be used in conjunction with the corresponding guide rail. When the size of the guide rail changes, its positioning accuracy and transmission stability will be greatly reduced, and even the position of the guide rail will shift during transmission. more serious consequences. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a rectangular linear guide...
