Automatic grinding system for car roof welding seam

Abstract

The invention discloses an automatic grinding system for a car roof welding seam. The automatic grinding system comprises an industrial robot, a grinding unit and a grinding plate abrasion monitoringunit; the grinding unit is installed on the industrial robot; the grinding plate abrasion monitoring unit is electrically connected with the industrial robot; the industrial robot is used for drivingthe grinding unit to grind the welding seam; after the welding seam is ground, the grinding plate abrasion monitoring unit is used for detecting the grinding abrasion degree of the grinding plate positioned on the grinding plate and comparing the grinding abrasion degree with the initial data of the grinding plate; and if the abrasion degree of the grinding plate is beyond a nominal value, the industrial robot is used for automatically replacing the grinding plate. The automatic grinding system disclosed by the invention can output constant and stable pressure and torque by a design-optimizedfloating module and preferably guarantees the grinding quality; the grinding plate detecting device can realize on-line measurement on abrasion degree of a grinding wheel and can realize automatic replacement of the grinding plate; and a dust removing device can be used for collecting and removing the grinding dust so that the cleanness and beauty of the welding seam are guaranteed, and the dust can also be prevented from being scattered in the air so as not to affect a human body.

Description

technical field [0001] The invention relates to vehicle roof grinding equipment, in particular to an automatic grinding system for vehicle roof weld seams. Background technique [0002] After the roof of the body-in-white is welded by laser, a small amount of spatter will be generated during the welding process, which will cause unevenness of the weld seam and slightly uneven weld seam after welding, which will affect the processing of the next procedure, resulting in uneven weld formation. It is beautiful, so the grinding treatment of the weld seam after welding is a necessary process. At present, the existing grinding equipment and grinding system, its grinding force, grinding speed and other process parameters are difficult to control, and the grinding quality is difficult to guarantee; secondly, in the grinding process, the real-time compensation of the grinding position cannot be realized, and the debugging requirements of the robot and The clamping and positioning req...

Problems solved by technology

[0002] After the roof of the body-in-white is welded by laser, a small amount of spatter will be generated during the welding process, which will cause unevenness of the weld seam and slightly uneven weld seam after welding, which will affect the processing of the next procedure, resulting in uneven weld formation. Beautiful, so the grinding treatment of the weld seam after welding is a necessary process

At present, the existing grinding equipment and grinding system, its grinding force, grinding speed and other process parameters are difficult to control, and the grinding quality is difficult to guarantee; secondly, in the grinding process, the real-time compensation of the grinding position cannot be realized, and the debugging requirements of the robot and The clamping and positioning requirements of the tooling fixture are relatively high

In addition, the dust removal cover in the existing grinding system cannot realize the self-adaptive adjustment of the Z axis according to the loss of the grinding sheet, which not only affects the frequency of use of the grinding sheet, increases the cost, and reduces the production efficiency, but also is difficult to control the dispersion of dust, causing harm to the human body. harm
