Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a drilling and tapping machine. Background Art

[0002] Drilling and tapping machines, as important equipment in the field of modern mechanical processing, integrate the two major functions of drilling and tapping into one, greatly improving processing efficiency and precision. The equipment adopts advanced transmission and cutting technology, and transmits power to the drill bit and tap accurately through a high-precision transmission system, ensuring accurate drilling and internal thread processing on a variety of materials such as metal and plastic. Drilling and tapping machines are usually equipped with adjustable speed and feed speed to adapt to different materials and processing requirements. At the same time, their sturdy structural design ensures stability and durability under high-load operations. With the integration of CNC technology, modern drilling and tapping machines have been able to realize automated and intelligent processing processes, which not only improves production efficiency but also reduces human errors. They are widely used in many industries such as automotive manufacturing, aerospace, and electronic equipment.

[0003] During metal processing on a tapping machine, the interaction between the drill or tap and the workpiece material inevitably produces metal shavings. These shavings are a byproduct of the machining process, and their shape, size, and quantity are influenced by a variety of factors, including the workpiece material, cutting parameters (such as rotational speed and feed rate), tool type, and wear. The presence of these shavings poses challenges to the machining environment and workpiece quality. If not promptly removed, they can cause tool blockage, scratches on the workpiece surface, machine failure, and even threaten operator safety.

[0004] Patent document CN201720559U discloses a structural schematic diagram of an embodiment of an automatic tapping machine, which includes an ordinary drilling machine 1, a drill arm 2, a tapping console 3, a feed conveyor 4, and a pusher 5. The tapping console 3 is located below the drill arm 2 of the ordinary drilling machine 1, and the feed conveyor 4 is located next to the tapping console 3 and is connected to the tapping console 3. The pusher 5 is facing the tapping console. During operation, the feed conveyor 4 transports the workpiece to the tapping console 3, which is pushed by the pusher 5 to the bottom of the drill arm 2 of the ordinary drilling machine 1. The pusher 5 returns to its position and immediately starts downward tapping under the action of the internal program controller of the tapping console 3. After the tapping is completed, it returns to its position, the workpiece is pushed out, and then the above process is repeated for continuous processing.

[0005] As in the prior art of the aforementioned patent, although the tapping machine uses a conveyor to automatically transport the components to be tapped during its workflow, it lacks a dedicated fixing assembly underneath the tapping machine to stabilize the components. This can cause the components to slide relative to each other during the tapping process, thereby affecting the precision and effectiveness of the tapping. Furthermore, metal debris generated by the tapping operation will scatter on the workbench. If not cleaned up in a timely manner, this debris will not only interfere with subsequent tapping operations but may also adversely affect the performance of the tapping machine and the quality of the workpiece. Therefore, the need to fix the components and the presence of debris will both affect the stability of the tapping process. Utility Model Content
