Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arm parts processing, in particular to a deburring device used for precision mechanical processing of mechanical arm parts. Background Art

[0002] The robot arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, the robot arm has been widely used in industrial assembly, safety and explosion-proof and other fields. Robot arm parts are the various components and accessories that make up the robot arm. These parts include but are not limited to the main structure, joints, drivers, sensors, connectors, etc. of the robot arm. These parts work together to enable the robot arm to complete various complex operating tasks. Precision machining is a process of high-precision changes in the size or performance of a workpiece. When precision machining robot arm parts, in order to ensure the accuracy and smoothness of the robot arm parts, thereby improving the overall working performance and stability of the robot arm, a deburring device is usually used to deburr the parts. The deburring device is a device or tool specifically used to remove burrs on the surface of mechanical parts. Burrs are usually caused by plastic deformation, casting, die forging and other processing methods during cutting, or residual materials extruded by welding. By removing burrs, the smoothness and finish of the surface of the parts can be ensured, thereby improving the quality of the robot arm, and at the same time, it can reduce the jamming or poor connection of parts during assembly, which is conducive to improving the assembly efficiency of the robot arm.

[0003] In the prior art, when deburring robot parts is performed by a deburring device, the parts are generally placed directly on a processing table, and the burrs on the surface of the parts are removed by rotating a grinding disc. Since the parts to be deburred cannot be well fixed, the parts are prone to displacement during the deburring process, which in turn affects the deburring effect and quality, and is not conducive to the processing of the robot arm. Therefore, in order to solve the above problem, a deburring device for precision machining of robot arm parts is proposed. Utility Model Content
