Abstract

The invention discloses a straight line locator using synchronous belts. The straight line locator comprises a substrate and a moving platform. A guide rail and a substrate synchronous belt are arranged on the substrate. The moving platform comprises a support, a sliding block, a motor, a moving platform synchronous belt and a belt gear. The sliding block is arranged on one side of the support and can slide along the guide rail. The motor is arranged on the sliding block. The belt gear is arranged on the other side of the support and is connected with an output shaft of the motor. A large guide wheel and a guide block are arranged on the two sides of the belt gear. The moving platform synchronous belt is simultaneously meshed with the belt gear and the substrate synchronous belt. The large guide wheel and the guide block are arranged on the moving platform synchronous belt and are in contact with the moving platform synchronous belt so as to ensure that the moving platform synchronous belt is meshed with the substrate synchronous belt. The straight line locator still can work well on the condition that the synchronous belts lack teeth or installing clearance exists between the rigid substrate and the synchronous belts, so that detection and repair cost in production utilization is reduced, and the matching problem caused by the utilization of different substrates is solved at the same time.

Description

technical field [0001] The invention relates to a linear positioning device, more specifically, to a linear positioner using a synchronous belt applied to a machine tool or a rectangular coordinate robot arm. Background technique [0002] Linear positioning equipment is one of the most basic motion kits in the field of machinery manufacturing and automation. Traditional linear positioning equipment consists of bases, guide rails, sliders, screw rods and other components. Its function is to convert the rotary motion of the motor into the linear motion of the slider, so as to realize the task requirements of the working space. In addition to the screw guide mode, emerging technologies such as linear motors are also widely used in the field of machinery manufacturing and automation. Reducing manufacturing costs, reducing environmental and lubrication requirements is a challenging goal in the manufacture of linear positioning equipment. [0003] In some environments with a lo...
