[0002] A woodworking drill bit magazine is an indispensable tool storage structure in woodworking machinery. It integrates various specifications and types of drill bits and is designed to meet the diverse drilling needs in woodworking. However, the tool holders of current six-way drill bit magazines are either inconvenient to access drill bits, or the design for facilitating automatic drill bit access results in unstable drill bit clamping, which can easily lead to drill bits falling off, affecting production, and even causing safety accidents. Utility Model Content

[0003] Based on the aforementioned problems in the existing technology, this utility model provides a six-tool magazine assembly structure for six-sided drilling, including a tool magazine base plate, on which six tool holders are fixedly installed, and each tool holder is fixedly installed with a drill bit. The drill bit includes a cylindrical tool holder, with a cutter head fixedly installed at the center of one end of the tool holder, and a connection structure for connecting with a drilling machine provided at the other end of the tool holder. A snap-fit ​​groove is provided on the periphery of the tool holder; the tool holder is provided with a C-shaped tool groove that matches the tool holder, the angle span of the C-shaped tool groove is greater than 180°, and a snap-fit ​​protrusion that matches the snap-fit ​​groove is provided on the inner wall of the C-shaped tool groove.

[0004] The diameter of the end of the tool holder with the connecting structure is larger than that of the connecting structure, thus forming a limiting platform. The limiting platform is provided with several limiting notches to restrict the relative rotation of the tool holder and the drilling rig.

[0005] The tool holder has a clamping opening at the opening of the C-shaped tool groove, with the diameter gradually increasing outwards.

[0006] The tool holder has a V-shaped deformation buffer groove on the side opposite to the opening of the C-shaped tool groove.

[0007] The six-tool magazine assembly structure for six-sided drilling further includes a mounting base plate, on which a slide rail is fixedly mounted. A slider that slides and engages with the slide rail is fixedly mounted on the tool magazine base plate. The tool magazine base plate is slidably mounted on the mounting base plate through the cooperation of the slider and the slide rail. A drive cylinder is also fixedly mounted on the mounting base plate. The telescopic end of the drive cylinder is fixedly connected to the tool magazine base plate, and the drive cylinder drives the tool magazine base plate to slide along the slide rail.

[0008] The tool magazine base plate has a mounting bracket fixedly installed on its upper surface, with two tool holders fixedly installed on the mounting bracket and the remaining four tool holders fixedly installed on the upper surface of the tool magazine base plate.

[0009] The beneficial effects of this utility model are:

[0010] 1. The structure of the tool holder and tool support has been optimized and improved. The C-shaped tool groove is used to clamp and restrict the movement of the tool support in the horizontal direction, and the cooperation of the locking groove and locking protrusion ring is used to restrict the movement of the tool support in the vertical direction, ensuring the stability of the tool support clamping and reducing the risk of falling. At the same time, the opening of the C-shaped tool groove facilitates the automatic removal and return of the drill bit.

[0011] 2. The tool magazine base plate and the mounting base plate are slidably connected. The tool magazine base plate can be slid by a drive cylinder, which can improve the flexibility of the equipment and the user experience. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] As attached Figure 1-7The diagram illustrates a six-tool magazine assembly structure for a six-sided drill, comprising a mounting base 1 and a tool magazine base 2. A quadrangular prism-shaped slide rail 3 is fixedly mounted on the mounting base 1. A U-shaped slider 4, which slides along the slide rail 3, is fixedly mounted on the tool magazine base 2. The tool magazine base 2 is slidably mounted onto the mounting base 1 via the cooperation of the slider 4 and the slide rail 3. A drive cylinder 5 is also fixedly mounted on the mounting base 1, with its extension end fixedly connected to the tool magazine base 2. The drive cylinder 5 drives the tool magazine base 2 to slide along the slide rail 3. A mounting bracket 6 is fixedly mounted on the upper surface of the tool magazine base 2, and two tool holders 7 are fixedly mounted on the mounting bracket 6. Four more tool holders 7 are fixedly mounted on one side of the mounting bracket 6 on the upper surface of the tool magazine base 2, for a total of six tool holders 7, arranged in two layers. The two tool holders 7 mounted on the mounting bracket 6 are on the upper layer, and the remaining four tool holders 7 are on the lower layer. This design effectively utilizes space and avoids the tool magazine occupying too much space in one direction.

[0021] Each tool holder 7 is fixedly equipped with a drill bit 8, which includes a cylindrical tool base 9. A drill head 10 is fixedly installed at the center of one end of the tool base 9. Different drill bits 8 can be equipped with standard drill heads of different specifications or functions. The other end of the tool base 9 is provided with a standard conical connecting structure 11 for connecting with the drilling rig. Both the drill head 10 and the connecting structure 11 can adopt existing technologies. The periphery of the tool base 9 is provided with a snap-fit ​​groove 12. The tool holder 7 is provided with a C-shaped groove 13 that matches the tool base 9. The angle span of the C-shaped groove 13 is greater than 180°. The inner wall of the C-shaped groove 13 is provided with a groove that matches the snap-fit ​​groove 12. The tool holder 9 has a snap-fit ​​protrusion 14; the diameter of the end of the tool holder 9 with the connecting structure 11 is larger than the connecting structure 11, forming a limiting platform 15, which facilitates the limiting and positioning of the drill bit 8 when the drilling rig automatically installs it. The limiting platform 15 is symmetrically provided with two limiting notches 16 to limit the relative rotation of the tool holder 9 and the drilling rig. The tool holder 7 has a clamping mouth 17 with a gradually increasing diameter at the opening of the C-shaped tool groove 13, which facilitates the tool holder 9 to enter the C-shaped tool groove 13. The tool holder 7 has a V-shaped deformation buffer groove 18 on the side opposite to the opening of the C-shaped tool groove 13, which allows the tool holder 7 to undergo elastic deformation when subjected to force, which facilitates the entry and exit of the tool holder 9 and the use of the drill bit 8 by the drilling rig.

[0022] The six-tool magazine assembly structure provided in this embodiment is part of the structure of a woodworking six-sided drilling machine. It is installed on the woodworking six-sided drilling machine and used. The drive cylinder 5 can drive the tool magazine base plate 2 and all the drill bits 8 to move, which improves the flexibility of the equipment and can avoid the tool magazine from affecting the operation of the drilling machine.

[0023] When the drill bit is removed, the drill moves above the required drill bit 8 and moves downward. The drill and drill bit 8 are automatically connected. Then the drill moves the drill bit 8 laterally and squeezes the tool holder 7, causing the tool holder 7 to undergo elastic deformation, and the drill bit 8 is separated from the tool holder 7.

[0024] When the drill bit is released, the drill rig moves the drill bit 8 to the clamp 17 of the tool holder 7, and then moves the drill bit 8 laterally and squeezes the tool holder 7, causing the tool holder 7 to undergo elastic deformation. The drill bit 8 enters the C-shaped tool groove 13 and the locking protrusion 14 is locked into the locking groove 12. The drill rig automatically releases the drill bit 8.
