Description

Technical Field

[0001] The invention belongs to the technical field of woodworking machinery, and in particular relates to a six-sided drilling head with double drill bags and automatic tool change. Background Art

[0002] In the contemporary panel furniture manufacturing industry, six-sided drilling and milling centers, a key technology, are widely used for the refined processing of panel materials. These centers, typically equipped with upper and lower processing units, a work platform, and a clamping and conveying system, secure the panel before precisely drilling or slotting it on all six sides. Compared to traditional multi-row drilling, PTP dual-arm drilling, and CNC five-side drilling, these centers offer higher efficiency and precision.

[0003] However, traditional six-sided drills face the problem of frequent tool changes in actual operation. Under normal circumstances, the tool is hung on a special tool holder, most of which are fixed or can only move a short distance. When the processing unit needs to replace the tool, it will move to the tool holder position to complete the replacement. However, the number of tools that can be carried on the tool holder is limited. When encountering complex plate processing tasks, a single tool holder is often difficult to provide all the required tools, resulting in processing interruptions. In addition, the stability of the tool holder may also affect the smooth installation of the tool, especially when the tool holder design is fixed or the range of movement is limited. The processing unit must adjust its position accordingly to cooperate with the tool change. This process not only consumes extra time, but may also cause the plate to be unstable due to changes in the position of the processing head, ultimately affecting the processing accuracy.

[0004] Therefore, it is necessary to study a six-sided drilling head with a double drill bag automatic tool change that can complete prop replacement without moving the processing head, so as to enhance the storage capacity of the six-sided drilling tool, improve the replacement efficiency and ensure the stability of the plate during the processing process.
