Problems solved by technology

In the past, the sponge wheel was manually trimmed. Due to the special R arc shape of the needle bar, it is difficult to manually trim the outer arc of the sponge wheel to meet the requirements of the workpiece. The consistency is not good, which affects the quality of the needle bar.
Due to the many times the needle bar works and the running speed is fast, if the processing quality is not good, the service life will be short and easy to be damaged
In addition, manual trimming is time-consuming and laborious.

Abstract

The present invention relates to a special polishing device for polishing wheel arc finishing and having an automatic dust-absorbing function. The special polishing device comprises a pedestal, a motor and sponge wheels; the motor is installed on an upper surface of the pedestal; the motor is connected with the sponge wheel and drives the sponge wheels; a vertical plate is installed on the pedestal at the rear of each sponge wheel; a sponge wheel finishing device is installed on each vertical plate; each sponge wheel finishing device comprises a swing rod and a finishing head; each swing rod is arranged to be inclined; each finishing head is installed at the front of the corresponding swing rod; and each finishing head is inclinedly arranged over the corresponding sponge wheel. The special polishing device is reasonable in design, simple in structure, high in practicality and convenient to use. The special polishing machine is equipped with the finishing devices for restoring the sponge wheels, consistency can be increased by using the finishing devices to restore the sponge wheels, the machined needle stem R arc are ensured to meet the demand, and the restoration speed can be accelerated.

Description

technical field [0001] The invention relates to the technical field of polishing machines, in particular to a special polishing equipment for automatic dust collection and polishing wheel trimming arcs. Background technique [0002] During the production process of the needle bar of an industrial sewing machine, it is necessary to use a polishing machine to process the R arc on the outer diameter of the needle bar connected with the shaft hole of the needle bar. After the sponge wheel of the polishing machine has been used for a period of time, its outer circle needs to be repaired. In the past, the sponge wheel was manually trimmed. Due to the special R arc shape of the needle bar, it is difficult to manually trim the outer arc of the sponge wheel to meet the requirements of the workpiece. The consistency is not good, which affects the quality of the needle bar. Because the needle bar works many times and runs fast, if its processing quality is not good, its service life i...
