Description

Technical Field

[0001] This utility model relates to the technology of woodworking machinery processing, and in particular to a multi-position pressing device for a six-sided drill. Background Technology

[0002] With the development of technologies such as automation and artificial intelligence globally, companies across various industries are increasing their efforts to deploy automation and intelligent manufacturing. "Replacing humans with machines" has become a major trend in the furniture manufacturing industry. Given the current difficulty in recruiting professional carpenters and the demand for craftsmanship in the furniture manufacturing industry, the requirements for woodworking equipment are becoming increasingly stringent. In particular, for the complex hardware accessories and processing techniques in the high-end custom industry, the traditional six-sided CNC drilling center equipment for woodworking is finding it increasingly difficult to meet customer needs.

[0003] For example, Chinese Publication No. CN217802169U discloses a six-sided drilling and pressing structure, including a cutting spindle, a dust cover, and a bakelite pressing plate. The cutting spindle is mounted on the upper end of the dust cover, and a first cylinder is connected to the upper end of the dust cover. The bakelite pressing plate is slidably connected inside the dust cover. The middle of the bakelite pressing plate has a clearance hole that mates with the cutting spindle. An air inlet pipe is connected to the upper end of the bakelite pressing plate, and air float holes are evenly distributed on the lower end face of the bakelite pressing plate. A dust suction pipe is connected to the upper end of the dust cover. Although it uses a bakelite pressing plate capable of venting air... The cutting spindle engages with the middle of the bakelite pressure plate during the cutting process, ensuring that the pressure plate always holds the board in place. However, the bakelite pressure plate is a fixed, enclosed structure. Different processing techniques, cutting tools, and pressure plate layouts result in varying pressure on boards of different sizes. Consequently, the fixed, enclosed structure of the single bakelite pressure plate makes it difficult to meet the pressure requirements for different processing positions, cutting tools, and processing techniques.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content
