Novel pipe inner wall processing device

Abstract

The invention discloses a novel pipe inner wall processing device. The novel pipe inner wall processing device comprises a rotary arm and a rotary cylinder connected with a drive device. Mounting grooves with outward openings are vertically and symmetrically formed in the rotary cylinder. A switching structure is arranged in each mounting groove. Movable grooves communicating with the mounting grooves are vertically and symmetrically formed in the rotary cylinder. A jacking press structure is arranged on each movable groove. A sliding groove is formed in the portion, located between the uppermovable groove and the lower movable groove, in the rotary cylinder. A drive structure is arranged in the sliding groove. A cavity communicating with the movable grooves is formed in the portion, on the right side of the sliding groove, of the rotary cylinder. The right side of the sliding groove extends into the cavity. The drive structure comprises a first motor fixedly arranged in the sliding groove, sliding sleeves and sliding blocks, wherein the sliding sleeves and the sliding blocks are slidably arranged in the sliding groove and located on the left side and the right side of the first motor. Threaded holes are correspondingly formed in the sliding sleeves and the sliding blocks. Threaded rods are mounted in the threaded holes in a threaded fit manner.

Description

technical field [0001] The invention relates to the field of pipe fitting processing, in particular to a novel pipe fitting inner wall processing device. Background technique [0002] During the processing of pipe fittings, it is often necessary to carry out anti-corrosion operations on its inner wall. Traditionally, anti-corrosion and anti-oxidation purposes are generally achieved by powder-coating anti-corrosion paint on the inner wall of pipe fittings. The inner wall of the pipe fitting needs to be polished before powder coating to remove acne. However, the structure of the existing grinding device is relatively simple, and it is difficult to achieve an ideal polishing effect. In order to improve the coating effect, there are many cleaning devices used to clean the inner wall of the polished pipe fittings, but the operation is extremely complicated and the cost of use is high. Therefore, the traditional processing device for the inner wall of pipe fittings has major defec...

The inner wall of the pipe fitting needs to be polished before powder coating to remove acne. However, the structure of the existing grinding device is relatively simple, and it is difficult to achieve an ideal polishing effect. In order to improve the coating effect, there are many cleaning devices used to clean the inner wall of the polished pipe fittings, but the operation is extremely complicated and the cost of use is high. Therefore, the traditional processing device for the inner wall of pipe fittings has major defects and needs to be improved.
