Description

A grinding auxiliary mechanism with floating function

technical field

The utility model relates to a grinding auxiliary mechanism with a floating function.

Background technique

The application of robotic grinding systems in modern industry is becoming more and more widespread. Due to the various tolerances of the workpieces that need to be polished in production, it is necessary to ensure that the grinding effects of different workpieces are consistent, and the grinding equipment must be able to achieve automatic compensation. In addition, robot grinding has a greater force than manual grinding. In order to avoid damage to the workpiece due to excessive force when the workpiece touches the grinding equipment, a floating mechanism needs to be installed to offset the excessive force. The existing methods are as follows: one is a spring structure for floating compensation, which is low in cost but cannot adjust the compensation in real time; the other is a variable-degree-of-freedom parallelogram swing mechanism, which can cooperate with springs and cylinders Combination control can realize the function of automatic compensation, but the structure is complex, the grinding equipment is large in size, resulting in excessive overall mass, large inertia, and insufficient sensitivity of the grinding float; one is that the sixth axis of the robot is equipped with a multi-dimensional force sensor, which can control Real-time monitoring of strength, but the cost of this structure is relatively high.
