The invention discloses a grinding tool used for grinding off coating of an elevator door. The grinding tool comprises a machine body and a work cavity arranged in the machine body, wherein the work cavity is opened leftwards and rightwards. A powder collection device capable of achieving powder collection and storage through a fan is arranged on the top wall of the work cavity. A conveying devicecapable of achieving elevator door conveying through a conveying belt is arranged in the bottom wall of the work cavity. Transverse moving cavities are symmetrically arranged in the left wall and theright wall of the work cavity. Transverse moving sliding blocks are arranged in the transverse moving cavities in a manner of being capable of moving front and back. The grinding tool transversely moves in a segmented manner through gear engagement and disengagement, whether the surface of the ground elevator door is coated or not is measured through a vortex distance measuring manner, when it isdetected that coating is not removed, the grinding tool is attracted by triggering an electromagnet to move backwards to grind the detection position, then detection is carried out again after springreturn, and coating on the elevator door is thoroughly treated through a repeated detection and grinding-off manner.

    本发明公开了一种用于磨除电梯门涂料的磨具,包括机身以及所述机身内设置有左右开口的工作腔,所述工作腔顶壁设置有通过风扇实现粉末收集储存的粉末收集装置,所述工作腔底壁内设置有通过传送带实现电梯门传送的传送装置,所述工作腔左右壁内对称设置有横移腔,所述横移腔内可前后移动的设置有横移滑块,本发明通过齿轮离合实现段落性的对磨具横向移动,又通过涡流测距的方式测量磨除过的电梯门表面是否还有涂装,检测到有涂装未去除进而触发电磁将磨具吸引后移对为检测位置进行磨除,随后通过弹簧回位后再次检测,经过反复检测磨除的方式将电梯门上涂装处理干净。
