Polishing mechanism with variable eccentricity and variable transmission ratio through eccentric adjustment block

Abstract

The invention discloses a polishing mechanism changing an eccentric value through eccentric adjusting blocks and changeable in transmission ratio. A shell is included, and a guide rail slider mechanism is fixed to the inner bottom of the shell; a base is fixed to a slider, and a top cover is fixed to the top of the base; first, second and third rotating shafts are rotationally connected between the top cover and the shell; the upper end face of a first belt wheel is connected with a lower workbench, and the eccentric adjusting blocks are fixed to the side faces of the lower workbench and an upper workbench; the upper end face of the upper workbench is connected with a speed reducer, and a servo motor is fixed to the speed reducer; an end cover is fixed to the top face of the shell, a connection flange is fixed to the end cover; a belt wheel, an overrun clutch and a gear are fixed to the first rotating shaft; two gears are fixed to the second rotating shaft, two gears are fixed to the third rotating shaft from bottom to top; a ball spline mother is fixed to the inner bottom of the base, and a belt wheel and a gear are fixed to the ball spline mother; and a cylinder connection pieceis fixed in the base, and a low-friction cylinder is fixed to the cylinder connection piece. By adopting the structure, the work efficiency can be substantially improved, and the polishing mechanism changing the eccentric value through the eccentric adjusting blocks and changeable in transmission ratio is suitable for actual production for use.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a polishing mechanism that changes the eccentric value through an eccentric adjustment block and has a variable transmission ratio. Background technique [0002] With the advancement of science and technology and economic development, the demand for aspheric optical components, especially large-diameter aspheric high-precision optical components, is increasing day by day. However, most of the existing polishing mechanisms are not high in precision, and their dynamic performance is not stable enough to meet the needs of optical components. Ultra-precision machining is required, and the polishing range and speed cannot be adjusted during the polishing process. Focusing on society's high-efficiency, high-reliability, and engineered processing requirements for aspheric components, the present invention conducts optimization research on a large-diameter aspheric robot numerical control...

Problems solved by technology

The overall structure is exposed, and a large amount of dust generated during the polishing operation will have a great impact on the operation of the mechanism. At the same time, the entire mechanism is driven by three motors, which has a low degree of modularization and a low degree of compact structure, and the eccentricity cannot be adjusted by fixed value.

[0004] The Chinese patent with the application number 201810233223.0 discloses "a lens polishing machine". The device includes a machine tool, a working chamber, an axle seat, a grinding head and other structures. It also has a pressure sensor system with a complex structure. The polishing liquid nozzle is separated from the grinding head. At the same time, the radius of the processable lens is too small. By using the thimble to press the lens against the grinding head for processing, it cannot meet the accuracy requirements of slightly high-precision optical equipment.
