Structural design of high-speed teeth rubbing machine (wire rubbing machine)

Screws are widely used in various industries such as machinery, electronics, motors, transportation, electrical appliances, furniture, and construction to facilitate the screw-locking connection between components. Moreover, with the continuous growth of the industry, the use of screws continues to increase, and always occupies an important position in the industrial market.

Among them, the screw is made by a tooth rubbing machine for the tooth rubbing operation, and the tooth rubbing machine is provided with a feeding device that can output the entire row of screw blast materials on a machine, and a tooth rubbing group is provided on the machine, the tooth rubbing plate has a movable tooth plate and a fixed tooth plate arranged in parallel,

A tooth rub channel is formed between the movable tooth plate and the fixed tooth plate. A guide rail is provided between the feeding device and the tooth rubbing plate group, and a pushing device is provided at the end of the guide rail that can push the output screw blast into the tooth rubbing plate group; so that when the tooth rubbing machine is actuated,

It transports the screw blast material to the tooth rubbing group through the guide rail at the feeding device, and then pushes it to the tooth rub channel by the pushing device to perform tooth rubbing operation. That is, when the movable tooth pad moves to the fixed tooth pad, the screw blast material can be clamped in the tooth rubbing channel to rub the screw tooth on the screw blasting material. However, although the above-mentioned tooth rubbing machine can achieve the expected effect of rubbing the screw blasting material, it is also found in its actual operation that when the screw blasting material is defective and tilted, it is pushed into the tooth rubbing channel by the pushing device, if the tooth rubbing machine continues to perform tooth rubbing operation, the screw blasting material is very easy to be stuck in the tooth rubbing channel, causing the tooth rubbing machine to be unable to continue the tooth rubbing operation. If troubleshooting is required, it is often necessary to remove the tooth rubbing group before the stuck screw blasting material can be removed, resulting in great inconvenience in production and use. This has resulted in room for improvement in its overall structural design.

During the tooth rubbing machine, if the screw blast material has defects and is skewed, the stepper motor can stop the rotating circular plate at any position. The No. 2 bump fixes the pushing member, so that the pushing member will not continue to push the screw blast material to prevent defects. The crooked screw blast material enters the tooth rubbing group and gets stuck in the tooth rubbing group, causing the tooth rubbing machine to be unable to continue to rub the teeth. The rubber sleeve can reduce the wear between the bump and the No. 2 bump, increase the friction between the bump and the No. 2 bump, and prevent the bump and the No. 2 bump from slipping. The pulley facilitates the movement of the pushing member.
