Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a pneumatic tapping device for nuts. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a machine. It's an essential component in all manufacturing machinery. Based on the material, nuts are categorized into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are crucial for tightly connecting mechanical equipment; they are joined together via internal threads, and only nuts and bolts of the same specifications can be connected.

[0003] During the machining process, nuts need to be tapped after being formed. Generally, the nut to be processed is fed into the tapping machine frame, and then the internal threads are machined using the tapping mechanism. Currently, most small nut tapping equipment still uses manual feeding, which poses significant safety hazards during loading and unloading, and the nut's position is prone to displacement during tapping, affecting the tapping effect.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0022] The working principle of this implementation plan: The electrical equipment used by this device is controlled by an external controller. When using it, the user first places the nuts that need to be tapped into the nut placement grooves 10 of a set of feeding plates 9 in sequence.

[0023] During alternating feeding: the drive motor 3 is mounted on the front end of the rectangular housing 1, and its rotating end is movably inserted into the rectangular housing 1 through a fastening bearing.

Then, the servo cylinder 11 continues to descend, and the rotary motor 13 drives the tap 14 to tap the nut. At the same time, the elastic clamping head 18 retracts and clamps the rear end of the nut. The elastic clamping head 18 uses a sliding rod in conjunction with a spring to achieve elastic retraction. The front end of the elastic clamping head 18 has a clamping groove corresponding to the nut. The bottom of the nut placement groove 10 has a round hole to facilitate the discharge of waste generated during tapping.
