Abstract

The invention belongs to the field of robot parts machining, and particularly discloses a single-degree-of-freedom high-bandwidth force-controlled grinding and polishing device and application thereof. The device comprises a connecting base, a driving module, a transmission module, a measuring module and a polishing module, wherein the connecting base is used for connecting the single-degree-of-freedom high-bandwidth force-controlled grinding and polishing device with the tail end of an industrial robot; the driving module is a vertically placed voice coil motor and comprises a stator and a rotor, the upper end of the stator is connected with the connecting base, and the lower end of the rotor is connected with the transmission module; the lower end of the transmission module is connectedwith the polishing module; and the measuring module is used for measuring displacement and contact force of the polishing module. According to the single-degree-of-freedom high-bandwidth force-controlled grinding and polishing device, the driving module adopts the voice coil motor, the displacement of the voice coil motor is adjusted in real time by controlling the input current of the voice coilmotor, so that the displacement and the contact force of the polishing module are adjusted in real time, and compared with an existing servo motor, the advantages of high response, high bandwidth andno need of conversion for linear driving are achieved, and the uniformity and consistency of the surfaces of complex curved surface parts are guaranteed.

Description

technical field [0001] The invention belongs to the field of robot part processing, and more specifically relates to a single-degree-of-freedom high-bandwidth force-controlled grinding and polishing device and its application. Background technique [0002] During the grinding and polishing process of large complex curved surface parts, the surface roughness directly affects its service life. Due to its complex profile and difficult processing, the commonly used methods are manual grinding and polishing and gantry machine tool grinding and polishing. Manual grinding and polishing has high technical requirements for workers, high labor intensity, low efficiency, and the consistency of products cannot be guaranteed, which seriously affects People's physical and mental health; the gantry machine tool has poor grinding and polishing flexibility, complicated operation, and it is difficult to solve the high-efficiency precision machining of the weak rigid area of ​​the middle and t...
