Flexible grinding mechanism

Abstract

The invention discloses a flexible grinding mechanism. The flexible grinding mechanism comprises an electric spindle, a cutter handle, an inner cylinder sleeve, an outer cylinder sleeve, an anti-rotating barrel and hinge pins, wherein the cutter handle is arranged at the lower end of the electric spindle. The hinge pins comprise the first hinge pins and the second hinge pins. The electric spindle is sleeved with the inner cylinder sleeve, the inner cylinder sleeve is sleeved with the outer cylinder sleeve, and the inner cylinder sleeve and the outer cylinder sleeve are connected through the two hinge pins. The outer cylinder sleeve is sleeved with the anti-rotating barrel, and the outer cylinder sleeve and the anti-rotating barrel are connected through the two second hinge pins. The first hinge pins and the second hinge pins are symmetric about the electric spindle respectively, and the connecting line of the first hinge pins and the connecting line of the second hinge pins are perpendicular to each other. Floating gaps are formed between the inner cylinder sleeve and the outer cylinder sleeve and between the outer cylinder sleeve and the anti-rotating barrel. According to the flexible grinding mechanism, in the working process, rigid contact between a cutter and a workpiece is avoided, the cutter, the electric spindle and a robot are protected, and service life is prolonged.

Description

technical field [0001] The invention relates to a grinding tool for a robot, in particular to a flexible grinding mechanism. Background technique [0002] After the casting is finished, the riser needs to be removed. Most of the riser should be cut off by flame cutting first, and the rest should be removed with tools. Using a robot to grind the riser is efficient and fast, but in actual operation, the hardness of the riser is very high, and the size and burrs of each casting are not completely consistent after cutting and removing the riser. If the grinding tool is in rigid contact with it , It is bound to cause great damage to the tool and the robot, the service life of the tool and the robot will be shortened accordingly, and it will also affect the grinding yield and the stability of the grinding quality. [0003] Therefore, it is necessary to develop a grinding flexible mechanism to overcome the above problems. Contents of the invention [0004] The purpose of the pr...
