Problems solved by technology

However, this device can only complete the free-form surface grinding on one side of the workpiece. When the product needs to be polished on the other side, the workpiece needs to be turned over and fixed on the workbench for grinding again. It cannot meet the three-dimensional grinding of cylindrical and conical polyurethane products, and the efficiency is low; In addition, since the device uses joint robots, it is costly and difficult to maintain

Abstract

A robot grinding device used for grinding polyurethane products comprises a linear moving mechanism, a mechanical arm, a grinding mechanism and a controller. One end of the mechanical arm is connected with the linear moving mechanism, and the other end of the mechanical arm is provided with a clamping claw used for clamping workpieces. The grinding mechanism is arranged on one side of the linear moving mechanism and is connected with an angle adjusting mechanism. The controller is connected with the linear moving mechanism, the mechanical arm, the grinding mechanism and the clamping claw. The robot grinding device is simple in structure and convenient to maintain, easily damaged parts are easy to replace, grinding automation of the polyurethane products is achieved, and three-dimensional grinding of the workpieces is achieved. An electric grinding head is used, the speed of the grinding head is precisely controlled, and grinding efficiency and grinding smoothness of the workpieces are improved. By means of the linear moving mechanism, operation is reliable and cost is low.

Description

technical field [0001] The invention relates to a technology in the field of industrial robots, in particular to a robot polishing device for polishing polyurethane products. Background technique [0002] In the grinding process of conventional polyurethane workpieces, except that the rotation of the grinding head is driven by a motor, other processes are completed by manual operation, which is a highly repetitive and cumbersome operation, which is not only inefficient, but also has high production costs and a large amount of labor, and the dust is harmful to the operator. It can take a lot of damage to your physical health. The structure of polyurethane products is often complex, including various complex curved surfaces and small-sized ribs with concave and convex shapes. Grinding such complex workpieces requires high precision, but manual operation is unstable and prone to mistakes, and the grinding force and stroke are difficult to control. The grinding operation time i...
