Description

Polishing device for elevator door plate machining

Technical Field

The utility model relates to the technical field of material processing, in particular to a polishing device for processing an elevator door plate.

Background

Elevator door panels are an important component of an elevator door system, mainly involving the car door and the door panel part of the landing door (also called elevator hoistway door) of an elevator. In the current door panel processing industry, although the automation and mechanization level is continuously improved, many factories still rely on traditional manual polishing modes for the door panel polishing step. Not only is this approach inefficient, but there are a number of technical challenges and limitations. Specifically, when the manual hand-held polishing tool polishes the door plate, the uniformity and consistency of polishing are difficult to ensure due to the limitation of human body strength and precision. More importantly, due to the lack of effective limiting and fixing measures on the door plate in the polishing process, the door plate is extremely easy to deviate or shake under the action of polishing force, so that the labor intensity of operators is increased, and the positions of the door plate are required to be continuously adjusted by the operators to ensure accurate polishing. The existing limiting device is often insufficient in design and application, and is difficult to meet efficient and accurate polishing requirements. These devices mostly employ simple clamping means, such as clamping the door panel by a clamp or a fixed bracket of a mechanical arm. However, such clamping methods often provide only an initial fixing effect, which is gradually weakened or even disabled during the polishing process for a long time due to vibration, abrasion, elastic deformation of the material itself, and the like. The door plate can be frequently moved in the polishing process, polishing precision and surface quality are affected, and potential safety hazards, such as injury accidents caused by sudden falling of the door plate, can be formed for operators. In addition, the manual polishing also faces the problems of high labor intensity, severe working environment, serious dust pollution and the like. In such working environments for a long time, the health of operators is extremely vulnerable to damage, such as occupational diseases like pneumoconiosis. Meanwhile, the efficiency and the precision of manual polishing are difficult to compare favorably with automatic and intelligent equipment, and the improvement of the whole development level and the economic benefit of the door plate processing industry is restricted to a certain extent.
