A special frame for adjusting the position of the hanging beam screw to the guide rail

Abstract

The invention provides a special fixture for adjusting the suspended beam lead screw position relative to a guide rail. The special fixture comprises a frame, two detection devices and two clamping devices, wherein the two detection devices and the two clamping devices are arranged on the frame; each clamping device comprises a screw, an assembling frame, a double-sided rack, two small gears, two large gears, two sliding racks, a replaceable claw clamp, a fixed claw clamp, a U-shaped groove, pressure sensors and a data collector; each double-sided rack is fixedly connected with the lower end of the corresponding screw; each two small gears are meshed with two sides of the corresponding double-sided rack respectively; each two large gears and the corresponding two small gears are coaxial and each two large gears are meshed with the corresponding sliding racks which are arranged below the large gears; each two sliding racks can slide freely in the corresponding U-shaped groove; a compression spring is arranged between each two sliding racks; each fixed claw clamp is rigidly connected below the corresponding sliding racks; each replaceable claw clamp is connected with the corresponding fixed claw clamp; each four pressure sensors are arranged on four sides of the corresponding replaceable claw clamp respectively. According to the special fixture for adjusting the suspended beam lead screw position relative to the guide rail, the structure is simple, the design is reasonable, the installation accuracy is high, the automatic detection can be achieved, the installation and the detection are integrated into a whole, the operation is simple, and the grasp is convenient.

Description

technical field [0001] The invention relates to the field of laser cutting machine manufacturing, in particular to a special frame for adjusting the position of a hanging beam screw to a guide rail. Background technique [0002] The adjustment method of the hanging beam lead screw of the existing laser cutting machine is to place the finished angle iron buckle on the guide rail surface of the machine tool, the magnetic base of the dial indicator is adsorbed on the angle iron, and first point the side head of the dial indicator to On the upper busbar of the lead screw, push the angle iron to drive the dial indicator to move along the direction of the guide rail, and record the runout value and the direction away from the center of each section of the lead screw; The iron drives the dial indicator to move along the direction of the guide rail, and records the beating value of each section of the screw and the direction of the offset center. Analyze the distance and direction ...
