Pressure-controllable industrial robot grinding and polishing system and grinding and polishing method

Abstract

The invention provides a pressure-controllable industrial robot grinding and polishing system. The pressure-controllable industrial robot grinding and polishing system is characterized by comprising apolishing device, a feeding device and a controller, and the polishing device comprises a fixed base, a mounting seat, a polishing mechanism, first slide rails, a position adjusting mechanism and a cylinder. The cylinder is connected with the mounting seat, and the mounting seat is slidably connected with the first slide rails to realize that the cylinder pushes the mounting seat to move in the length direction of the first slide rails to drive the polishing mechanism to move. The cylinder is connected with the controller to enable the controller to control the cylinder to control grinding pressure between the polishing mechanism and a workpiece. The cylinder is disposed on the fixed base through the position adjusting mechanism. The pressure-controllable industrial robot grinding and polishing system can improve grinding and polishing effects and improve production efficiency and product quality. The invention further provides an industrial robot grinding and polishing method which is capable of realizing constant grinding pressure between the polishing mechanism and the workpiece, effectively improving the grinding and polishing effects and improving the production efficiency and the product quality.

Description

Technical field [0001] The invention relates to the technical field of grinding and polishing, and more specifically, to a pressure-controllable industrial robot grinding and polishing system and a grinding and polishing method. Background technique [0002] Grinding and polishing is to reduce the roughness of the workpiece surface, so as to obtain a bright, smooth surface processing technology. When grinding and polishing, the abrasive tool is pressed against the workpiece, and a certain grinding pressure is generated with the surface of the workpiece. Through the high-speed rotation of the abrasive tool, the abrasive tool produces rolling and micro-cutting on the surface of the workpiece to obtain a bright processing surface. [0003] However, the grinding end of traditional grinding and polishing equipment is mostly rigidly connected, and the polishing motor is fixed on the mounting table; during the grinding process, the grinding pressure between the grinding tool and the workp...

Problems solved by technology

[0003] However, the grinding end of traditional grinding and polishing equipment is mostly rigidly connected, and the polishing motor is fixed on the mounting table; during the grinding process, the grinding pressure between the abrasive tool and the workpiece is controlled by manually adjusting the distance between the polishing motor and the workpiece. The adjustment does not ensure that the grinding pressure of the abrasive tool and the workpiece is suitable. It requires the person who adjusts to have rich experience, and when changing different workpieces, it needs to be adjusted again, which is not conducive to high-efficiency and high-quality production.

After grinding for a period of time, the abrasive tool will wear out, resulting in the reduction or even separation of the contact surface between the abrasive tool and the workpiece; at the same time, due to the processing error of the workpiece itself and the deviation of the tool taken and placed by the grinding and polishing equipment, the grinding point on the workpiece is prone to offset , the grinding point is prone to uneven force, and the grinding pressure between the workpiece and the abrasive tool is difficult to maintain constant

[0004] In the process of grinding and polishing, if the grinding pressure is too small, the flaws or defects on the surface of the workpiece cannot be completely removed; if the grinding pressure is too high, it will easily lead to excessive grinding, causing damage to the workpiece and the abrasive tool, so the gap between the abrasive tool and the workpiece The grinding pressure between them is the key to the grinding and polishing process

A small number of grinding and polishing equipment will install a spring in the grinding tool mechanism, and use the return elasticity of the spring to adjust the pressure between the grinding tool and the workpiece. However, the grinding pressure range and actual grinding pressure in this method cannot be known and controlled, so it cannot be guaranteed. Grinding and polishing effect and precision
