Liquid metal grinding disc self-repairing device with automatic grabbing function

Abstract

The invention discloses a liquid metal grinding disc self-repairing device with an automatic grabbing function. The liquid metal grinding disc self-repairing device comprises a three-degree-of-freedomdriving device, a rotary tripod head, a mechanical gripper, a gripper cylinder, a camera, a grinding disc, a machining station and a self-repairing station, wherein the three-degree-of-freedom driving device is arranged between the machining station and the self-repairing station; the rotary tripod head is arranged at a movable end of the three-degree-of-freedom driving device; the mechanical gripper is arranged at a rotary end of the rotary tripod head; the gripper cylinder is connected with the mechanical gripper and drives the mechanical gripper to open and close; and the camera is arranged at the rotary end, connected with the mechanical gripper, of the rotary tripod head. According to the liquid metal grinding disc self-repairing device, liquid metal and abrasive particles are uniformly mixed, the mixture of the liquid metal and the abrasive particles is injected into a grinding tool, and the liquid metal is slowly solidified into a solid through a cooling module so as to realizethe manufacturing of a grinding disc; and due to the characteristic of low melting point of the liquid metal, the forming of the grinding disc is fast, and the extremely high surface flatness can berealized through a self-leveling technology.

Description

technical field [0001] The invention relates to the field of liquid metal polishing, in particular to a self-repairing device for a liquid metal grinding disc with an automatic grabbing function. Background technique [0002] Grinding is the finishing process (such as cutting) of the machined surface by using the abrasive particles coated or pressed on the grinding tool, through the relative movement of the grinding tool and the workpiece under a certain pressure. The abrasive particles of the grinding disc are pressed into the surface of the grinding disc, and the surface of the workpiece is scored with the exposed abrasive tip to realize micro-cutting. When the sharp parts of the abrasive particles are worn out, new abrasive sheets need to be replaced, and the replaced abrasive sheets are discarded directly, which wastes materials and is not conducive to material recovery and utilization. The existing abrasive sheet will rub against the surface of the workpiece when grind...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problems that the existing grinding discs are difficult to self-repair during the processing process and the processing technology is complicated, waste materials, non-recyclable and poor precision in the manufacturing process, and a liquid metal grinding disc with automatic grabbing function is proposed. The repair device can accurately grab the grinding discs in the production process, transport them to the repair station for repairing, and can make the grinding discs by itself. The process of making the grinding discs is simple, and there will be no waste of materials and wear The grinding disc can also be recycled and used again, and the precision of the produced grinding disc is higher
