Hold-down mechanism for rail deburring

Abstract

The invention discloses a pressing mechanism for a guide rail deburring device. The pressing mechanism is arranged on a rack of the guide rail deburring device and comprises a clamping drive cylinder, a first connecting rod, a second connecting rod and a pressing component, wherein one end of the first connecting rod is hinged with the piston rod of the clamping drive cylinder, the middle part of the first connecting rod is hinged on the rack, one end of the second connecting rod is hinged with the first connecting rod, the middle part of the pressing component is hinged with the other end of the second connecting rod, one end of the pressing component is hinged on the rack, and the other end of the pressing component is provided with a bent pressing part for pressing a guide rail. By adopting the pressing mechanism for the guide rail deburring device, the guide rail can be fixed on the rack during the deburring process and cannot be driven by a vertically-moving steel wire roller to move, and the piston rod of the cylinder can move to drive the pressing component through the first connecting rod and the second connecting rod to overturn to press the guide rail. Compared with the pressing mode with vertical movement of the pressing component, smaller driving forces are needed by the cylinder, and the surface of the guide rail cannot be damaged.

Description

technical field [0001] The invention relates to a guide rail deburring device, in particular to a pressing mechanism for the guide rail deburring device. Background technique [0002] The elevator guide rail is a safe rail for the elevator to run up and down in the well. The guide rail is installed on the well wall, and is fixedly connected to the well wall by the guide rail frame and the guide rail bracket. Elevator guide rails have the characteristics of strong rigidity, high reliability, safety and low cost. The plane of the guide rail must be smooth, without obvious uneven surface, and the cross-section at both ends of the guide rail must be smooth and free of burrs. At present, the manufacturers of elevator guide rails (solid and hollow) all over the world will have burrs firmly stuck on the guide rails after metal processing, and need to be deburred. Existing deburring devices mostly use a rotating wire wheel for deburring, but the wire wheel will cause the guide rai...

AI Technical Summary

Problems solved by technology

Existing deburring devices mostly use rotating wire wheels for deburring treatment, but the wire wheel will cause the movement of the guide rail during the grinding process, which will affect the deburring effect, so it is necessary to press and fix the guide rail on the frame

The existing pressing mechanism mostly adopts the method of moving up and down, and the driving cylinder directly drives the pressing part to move up and down to compress and loosen the guide rail. This method requires a large driving force of the cylinder and will also cause certain damage to the surface of the guide rail. damage
