It is understandable that the above solution can also be used to improve the problem of hole opening accuracy.

[0022] In this embodiment, the workbench 101 is a rectangular table, which is installed on the workbench 101 through the positioning component, so that the plate can be centered, thereby solving the problem that the plate needs to be positioned in the initial stage of drilling, while most of the existing technologies only have a fixing mechanism and cannot be centered, thus affecting the drilling accuracy.

[0023] The mounting frame 102 is slidably connected to the workbench 101 and is located on one side of the workbench 101, the connecting frame 103 passes through the workbench 101 and is fixedly connected to the mounting frame 102, the shaft 104 is fixedly connected to the mounting frame 102 and is located inside the mounting frame 102, the clamping wheel 105 is sleeved on the outside of the shaft 104 and is rotatably connected to the shaft 104, the driving member drives the connecting frame 103 to move, the mounting frame 102 is a rectangular body with an internal cavity, there are two of them, they are symmetrically mounted on the top surface of the workbench 101, both of the two mounting frames 102 can slide laterally on the workbench 101, the opposite side of the two mounting frames 102 is an opening, which is convenient for the installation of the clamping wheel 105, the connecting frame 103 is U-shaped, a slot is provided on the workbench 101, and both ends of the connecting frame 103 pass through the workbench 101 through the slot. The connecting frames 103 are connected to the mounting frame 102, and the number of the connecting frames 103 corresponds to the number of the mounting frames 102. The shaft rod 104 is vertically installed in the inner cavity of the mounting frame 102. The number of the shaft rod 104 is multiple and evenly arranged along the length direction of the mounting frame 102. The number of the clamping wheels 105 is multiple and respectively sleeved on the multiple shaft rods 104 through bearings. The clamping wheels 105 extend out from the opening of the mounting frame 102 and are used to contact the side of the plate. The driving member is used to drive the two connecting frames 103 to move together or away from each other at the same time, and the two mounting frames 102 are driven to move together from both sides to the middle through the two connecting frames 103, thereby pushing the plate to move to the middle of the workbench 101, so as to realize the centering of the plate, and solve the problem that the plate needs to be positioned in the initial stage of drilling, and most of the existing technologies only have a fixing mechanism and cannot be positioned in the center, thereby affecting the drilling accuracy.

[0024] Secondly, the sliding groove 106 is located on one side of the workbench 101 close to the mounting frame 102; the protrusion 107 cooperates with the sliding groove 106, the sliding groove 106 is a T-shaped groove, located on the top surface of the workbench 101, and the protrusion 107 is located at the bottom of the mounting frame 102. Through the cooperation between the protrusion 107 and the sliding groove 106, the mounting frame 102 can move laterally on the workbench 101.
