Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0016] refer to figure 1 , a six-degree-of-freedom abrasive belt grinding unit attitude compensation device according to the present invention can be used in the abrasive belt grinding unit to form an automatic grinding system with an industrial robot. The traditional abrasive belt grinding unit is mainly driven by a motor fixed on the base plate 2 to move the active roller 1 . The base plate 2 is made of aluminum alloy plate, and the driving roller 3 is a cylindrical roller with aluminum core covered with rubber, and its outer surface is provided with a spiral chute. of friction. The abrasive belt 6 bypasses the first driven roller 3 , the second driven roller 4 ,...

Abstract

The invention discloses a six-degree-of-freedom posture compensation device for an abrasive belt grinding unit. Air spring housings and air spring piston rods form elastic supporting rods, and the air spring housings are hinged to a posture compensation plate and a base plate through second ball knuckle bearings and first ball knuckle bearings correspondingly; a first length adjustment rod, a second length adjustment rod and a third length adjustment rod are connected between each air spring housing and the corresponding first ball knuckle bearing; the posture compensation plate is rectangular, two elastic supporting rods are arranged on one side of the posture compensation plate, and the other elastic supporting rod is arranged on the other side of the posture compensation plate; and an ejection cylinder is fixed to the posture compensation plate, a piston rod of the ejection cylinder is fixedly connected with a grinding plate, and guiding shafts are fixed to the four corners of the grinding plate and inserted into guiding shaft sleeves fixed to the posture compensation plate correspondingly. By adoption of the six-degree-of-freedom posture compensation device for the abrasive belt grinding unit, the correction time is shortened when the abrasive belt grinding unit is matched with a robot for grinding, and the positioning level of the robot and the grinding unit is lowered; and meanwhile, the adaptability of a grinding system is improved, and the grinding quality of abrasive belts is improved.

Description

technical field [0001] The invention relates to the technical field of abrasive belt grinding and polishing, in particular to a six-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...
