Description

Technical Field

[0002] When processing nuts, a tapping machine is usually used to tap the inside of the nut. The working principle of the nut tapping machine is generally to rotate a rotating tapping tool inside the nut to form a thread.

[0003] The existing nut tapping machines are usually composed of a machine tool, a multi-station turntable, a tapping motor that can move up and down, and a vibrating loading plate.

The multi-station turntable rotates and transports the nuts to be processed to the bottom of the tapping motor, and the nuts can be tapped. However, when the nuts to be processed are manufactured, some nuts may be solid inside. When the solid nuts enter the station at the bottom of the tapping motor, the tapping tool on the tapping motor contacts the solid nut, and the solid nut will damage the tapping tool. It is not convenient to detect and remove the solid nuts when the nuts are transported to the multi-station turntable. Utility Model Content
