[0008] The utility model is further provided as follows: the output end of each lifting cylinder is withdrawn in the pressing plate state, and the pressing plate roller presses the wood board at the same time, the output end of the lifting cylinder is extended in the release state, and the pressing plate roller is separated from the wood board at the same time.

[0009] The utility model is further provided as follows: in the pressing plate state, each pressing plate roller is uniformly distributed on both sides of the wood board to be drilled, and the number of pressing plate rollers on both sides is the same.

[0010] The utility model is further provided as follows: a rubber sleeve is sleeved on the outer surface of the pressing plate roller.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention ensures that the wooden board is pressed and fixed during drilling by adjusting the pressure plate state of the pressure plate assembly, thus preventing displacement and ensuring high precision in the drilling position. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A high-precision wood board drilling machine, such as Figure 1 As shown, the system includes a machine base 1, a gantry beam 2, a Y-axis moving frame 3, and a machine head 4. Mounting frames 5, which move with the gantry beam 2, are installed at both ends. The machine base 1 is an integral support structure. The gantry beam 2 can move along the X-axis. The Y-axis moving frame 3 is slidably connected to the gantry beam 2 via guide rails and can move along the Y-axis. The machine head 4 is mounted on the Y-axis moving frame 3 and can move along the Z-axis. It has a built-in drive motor and drill bit for drilling operations. Mounting frames 5 are fixed at both ends of the gantry beam 2 and move synchronously with the gantry beam 2. Several pressure plate assemblies 6 are spaced apart between the two mounting frames 5 along the X-axis. Each pressure plate assembly 6 includes a pair of lifting cylinders 61, a pair of bearing seats 62, and a pressure roller 63. The lifting cylinders 61 are vertically fixed to the mounting frames 5. The two ends of the pressure roller 63 are connected to the bearing seats 62 via rolling bearings to ensure that the pressure roller 63 can rotate freely.

[0017] The pressure plate assembly 6 includes a pressure plate state and a release state, which can be switched between. When the machine head 4 is working, the pressure plate assembly 6 is in the pressure plate state; before drilling is completed or before drilling begins, the pressure plate assembly 6 is in the release state. In the pressure plate state, the output ends of each lifting cylinder 61 retract, and the pressure plate rollers 63 press against the wooden board. In the release state, the output ends of the lifting cylinders 61 extend, and the pressure plate rollers 63 separate from the wooden board. In the pressure plate state, the pressure plate rollers 63 are evenly distributed on both sides of the area where the hole is to be drilled, and the number of pressure plate rollers 63 on both sides is the same.

[0018] Pressing plate state (when drilling): the output end of the lifting cylinder 61 is retracted, driving the bearing seat 62 and the pressing plate roller 63 to move downwards, so that the pressing plate roller 63 tightly presses the surface of the wood board. At this time, the wood board 7 is provided with two pressing plate rollers 63 on both sides of the drilling area, which ensures the symmetry of pressure distribution and avoids the deviation of the wood board. When drilling, the pressing plate roller 63 can press the wood board, and when the gantry beam 2 moves, the pressing plate roller 63 can roll on the surface of the wood board and keep pressing the wood board, avoiding the sliding of the wood board and improving the drilling accuracy.

[0019] Release state (before drilling or after completion): the output end of the lifting cylinder 61 is extended, driving the bearing seat 62 and the pressing plate roller 63 to move upwards, so that the pressing plate roller 63 is completely separated from the wood board, facilitating the loading and unloading or position adjustment of the wood board.

[0020] The outer surface of the pressing plate roller 63 is sleeved with a rubber sleeve 7, and the outer surface of the pressing plate roller 63 is covered with the rubber sleeve 7, which can increase the friction and avoid scratching the surface of the wood board.

[0021] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application are also considered as the protection scope of the present application.
