Abstract

The invention discloses a two-DOF (degree of freedom) belt grinding unit attitude compensation device; elastic support rods are composed of an air spring shell and a piston rod, each elastic support rod is hinged respectively to a first attitude compensation plate / second attitude compensation plate and a base plate through a second spherical joint bearing and a first spherical joint bearing; a first length adjusting rod and a second length adjusting rod are connected between each spring shell and the corresponding first spherical joint bearing such that the length of the elastic support rod between the first and second spherical joint bearings may be changed; an ejection cylinder is fixed to the first attitude compensation plate / second attitude compensation plate, a piston rod of the ejection cylinder is fixedly connected to an abrasive plate, and the ejection cylinder is positioned within a four-point line area of the hinging points of the four second spherical joint bearings; a guide shaft is fixed to each of four corners of the abrasive plate. The two-DOF belt grinding unit attitude compensation device has the advantages that correction time for mating with a robot in grinding can be saved, the positioning level for a robot and a grinding unit is lower, applicability of a grinding system is improved, and grinding quality can be guaranteed.

Description

technical field

[0001] The invention relates to the technical field of abrasive belt grinding and polishing, in particular to a two-degree-of-freedom abrasive belt grinding unit attitude compensation device. Background technique

[0002] When using an abrasive belt grinder for grinding, skilled workers are required to hold the part and remove the burrs on the surface of the part. The cost of labor in China is rising rapidly, and the grinding and polishing industry deploys automation equipment to offset the rising cost. At present, the robotized grinding system uses the robot to grasp the parts and cooperate with the belt machine. The robot needs to cooperate precisely with the grinding machine to ensure the processing quality. When the robot clamps the workpiece to grind on the abrasive belt grinding unit, it needs to make hard contact with the abrasive belt to maintain sufficient grinding force. Since the grinding system is operated by the industrial robot and the grinding...
