Description

Technical Field

[0001] The utility model relates to the field of multilayer board processing, in particular to an auxiliary device for opening holes in multilayer boards. Background Art

[0002] The multilayer board is a three-layer or multi-layer plate-like material made by peeling wood segments into single boards or planing wood squares into thin wood, and then gluing them with adhesives. It is usually made of odd-numbered single boards, and the fiber directions of adjacent single boards are made perpendicular to each other. The patent office database search shows a multilayer board hole-opening device with publication number CN215149881U. When the servo motor is started, the servo motor can drive the drill bit to rotate, and then the balls in the multiple support blocks are placed on the wooden board, and then the device is moved so that the device moves parallel to the wooden board, so that the drill bit and the wooden board remain perpendicular. When the drill bit is located at the position where a hole needs to be drilled, the pull rod is grasped, and then the drill bit is pressed downward to drill. However, when the drill bit is drilling holes in the multilayer board, the balls are spherical, which can easily cause the drill bit to deviate, and the drill bit cannot penetrate the multilayer board, so that the bottom drilling effect of the multilayer board is not good.

[0003] Therefore, it is necessary to invent an auxiliary device for opening holes in multilayer boards. Utility Model Content
