Electric control type polishing device with adjustable polishing radius

Abstract

The invention discloses an electric control type polishing device with an adjustable polishing radius, and relates to the technical field of polishing devices.The electric control type polishing device comprises a fixing frame, wherein a driving motor is mounted on the top of the fixing frame, an output end of the driving motor is coaxially and fixedly connected with a control block, a rotating speed sensor is mounted at the output end of the driving motor, the control block is rotatably connected to the bottom of the fixing frame, a plurality of narrow-opening sliding grooves are formed in the bottom of the control block in a radial mode, and the ends, far away from the control block, of the narrow-opening sliding grooves penetrate through the control block and are internally connected with sliding blocks in a sliding mode. When a large plane of a workpiece is polished, the rotating speed of the output end of the driving motor is increased to drive the control block to rotate at a high speed, the sliding blocks connected to the control block in a sliding mode control part of an elastic force of a spring under a centrifugal effect, and the sliding blocks slide outwards along the narrow-opening sliding grooves in the control block, so that a polishing radius of each sliding block is increased, and the polishing range is enlarged, and meanwhile, the polishing efficiency to the surface of the workpiece is doubly improved in a high rotating speed state.

Description

Technical field[0001]The present invention relates to the field of polishing apparatus, and more particularly to a polishing apparatus for an electrically controlled polishing radius.Background technique[0002]During the processing of the workpiece, it is often necessary to polish the workpiece surface to smooth, optimize the performance and appearance of the workpiece. In the polishing process of the workpiece, the polishing disc structure of the existing polishing machine is fixed, and the polishing range cannot be changed, and the different polishing environments cannot be adapted in the polishing process, and polished the large plane. When it is impossible to increase the polishing efficiency in the polishing radius, it cannot effectively bond the polishing effect on some smaller corners.Inventive content[0003]The polishing apparatus for a discharged-adjustable polishing radius proposed in the present invention is to solve the problem of the polishing scope of the polishing disk ...
