Surface polishing device for cylindrical parts

Abstract

The invention provides a columnar part surface polishing device. The columnar part surface polishing device aims at solving the problems that in the prior art, the workpiece surface machining accuracy is not high, and bounce is generated due to uneven workpiece stress; and the columnar part surface polishing device comprises a base, a left support, a right support and a polishing mechanism, and the above polishing mechanism comprises a movement mechanism and a polishing assembly. The movement mechanism comprises a set of lead screw bases fixed to the left support and the right support correspondingly, a rotating shaft, a hand wheel, a handle, a lead screw gear, a movement mechanism driven gear and a set of parallel lead screws. The polishing assembly comprises a polishing base installed on the lead screws in a matched manner, an oil cylinder arranged on the polishing base, a polishing support connected to the output end of the oil cylinder, a polishing motor installed on the polishing support and a polishing brush. The position of the polishing assembly is adjusted by controlling the movement mechanism, so that polishing work is done on columnar parts; and the set of lead screws arranged in parallel can effectively control the stability of the polishing assembly.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing and processing, in particular to a surface polishing device for cylindrical parts. Background technique [0002] Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The machinery manufacturing industry is the most basic industry of a country, and it also determines the overall level of a country's manufacturing industry. Its development level directly affects the improvement of the national economic level. [0003] Polishing is a finishing method. Generally, a disk made of soft material is used to make a disc adhered to free abrasive grains for high-speed rotation, and press it against the workpiece for grinding, thereby improving the brightness of the workpiece surface and reducing th...

Problems solved by technology

[0004] At present, in the polishing process of existing polishing devices, on the one hand, the length of the columnar parts is relatively high, and polishing mechanisms of different sizes are usually selected according to the length of the columnar parts to be processed, and the application range of the polishing machine is narrow; on the other hand, often Because the pressure and speed are not well controlled during polishing, the surface processing accuracy of the workpiece is not high, and the ideal effect cannot be achieved. What's more, the pressure at a certain point of the workpiece is too high, which may easily cause the workpiece to break and jump due to uneven force. Seriously affect the life safety of staff
