Quick-replacement grinding tool for automatic grinding by robot

Abstract

The invention discloses a quick-replacement grinding tool for automatic grinding by a robot. The quick-replacement grinding tool comprises a connection cone matched with an electric spindle tool clamping jaw and the like, wherein a clamping slot connected with a tool frame is located on one side of the connection cone matched with the electric spindle tool clamping jaw; a manual quick-disassembly wedge slot is located between the clamping slot connected with the tool frame as well as a rear backing plate; the connection cone matched with the electric spindle tool clamping jaw, the clamping slot connected with the tool frame and the manual quick-disassembly wedge slot are all located on a front and rear backing plate threaded rod; one end of the front and rear backing plate threaded rod penetrates through a grinding wheel to be in threaded connection with a flat nut; the rear backing plate and a front backing plate are located on two sides of the grinding wheel; an anti-loose washer is located between the front backing plate and the flat nut. With the adoption of the quick-replacement grinding tool, the grinding tool can be replaced quickly, accurately and automatically, the automation level of robot grinding is further improved, the overall structure is light in mass and small in size, the center of gravity is in the axis, the dynamic balance is good, and accordingly, the grinding tool cannot shake during high-speed rotation.

Description

technical field [0001] The invention relates to a grinding tool for grinding, in particular to a quick-change grinding tool for automatic grinding by a robot. Background technique [0002] In the field of robotic automatic grinding, abrasive tools must be replaced when worn to a certain extent to ensure the quality and efficiency of grinding and the automatic operation of grinding. The traditional robot grinding head needs to add an abrasive wear detection device. After each grinding, the abrasive wear needs to be inspected. When the wear of the abrasive reaches the replacement standard, the entire station will stop and an alarm will be issued. Manual removal and replacement of the abrasive is required. It cannot solve the shutdown accident of the automobile production line caused by manual replacement of abrasive tools, and cannot improve the overall efficiency of the automobile production line. In the automobile body manufacturing workshop, the automobile production cycle ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a quick-change abrasive tool for automatic grinding by a robot, which solves the problem that the robot can quickly, accurately and automatically replace the abrasive tool during the grinding process, and further improves the automation level of the robot grinding; through the design The unique short and small handle, and a grinding wheel is added to the end of the short and small handle to realize the integration of the handle and the abrasive; in actual use, the robot can automatically grind the handle by automatically grabbing the handle with a six-axis end grinding device. The automatic replacement of abrasive tools ensures that the whole process is controllable and adjustable. By introducing the tool library, the entire grinding station can be automatically replaced without manual participation. Through the special telescopic device of the grinding head, the grinding process can be realized. Abrasive wear detection does not need to add additional detection devices and detection procedures, saving the entire grinding time, which is conducive to improving the overall efficiency of grinding and realizing the automation of grinding; the overall structure is light in weight, small in size, and the center of gravity is on the axis, with good dynamic balance. , to ensure no jitter during high-speed rotation
