Equipment and technique for automatically grinding tooth profile fillet of precision gear by robot

Abstract

The invention discloses equipment and technique for automatically grinding a tooth profile fillet of a precision gear by a robot. A robot module in the equipment is arranged on one side of a workbench module, and a grinding tool module is installed on an end effector of the robot module; a forming tool is installed at the front end of a pneumatic engraving and grinding machine in the grinding tool module, and the pneumatic engraving and grinding machine is connected with the upper plate surface of an XY-horizontal sliding table through a clamp and a first L-shaped connecting plate; the XY-horizontal sliding table is used as a position adjusting device of a template and is connected with the template through a connecting plate, and a tool setting gauge is installed on the same side of the template; an air cylinder is installed on the end effector of the robot module through a second L-shaped connecting plate; and a piston of the air cylinder is connected with the first L-shaped connecting plate. According to the equipment and the method, the distance between the tool and the tooth profile line can be ensured to be constant in the grinding process, the machining quality problem caused by the positioning error of the robot is avoided, and meanwhile, a force sensor is not adopted for error adjustment compensation, so that the cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of automatic processing and application of industrial robots, in particular to equipment and a process method for automatic grinding of precision gear tooth profile fillets by robots. Background technique [0002] The gears in high-precision transmission and transmission equipment such as hydraulic pumps and gearboxes have high manufacturing precision and complex structures, making the production and processing of such gears very difficult. [0003] The tooth profile transition fillets of precision gears are usually processed by grinding due to their small size and high precision. The cost of grinding the gear tooth profile fillets with CNC machine tools will be greatly increased, and compared with various complex shapes and various structures For high-precision gears, the flexibility and adaptability of CNC machine tools are poor, and the working space of the machine tools will also limit the grinding of th...
