[0018] The embodiments of the utility model will be described in detail below with reference to the drawings, so that the purpose, characteristics and advantages of the utility model can be more clearly understood. It should be understood that the embodiments shown in the drawings are not a limitation on the scope of the utility model, but only for explaining the essential spirit of the technical scheme of the utility model.

[0019] AsFigure 1 The utility model provides a special machine tool for anchor plate drilling, including ground foundation 6, rotary worktable 8, power slide 5 and numerical control power head 4, numerical control power head 4 has multi -shaft drill bit 041, rotary worktable 8 sets up on ground foundation 6 for fixed anchor plate 2, power slide 5 is located on the periphery of rotary worktable 8 ground foundation 6, power slide 5 is connected with numerical control power head 4 on the sliding, numerical control power head 4 is used to move along power slide 5 and make multi -shaft drill bit 041 be located in the upper rotary worktable 8 to anchor plate 2 carries out drilling.

[0020] Specifically, numerical control power head 4 is derived from the existing drilling machine, and the drilling machine is used for drilling on the inner diameter of a large direct drive rotor. The numerical control power head 4 of the drilling machine is installed on the workbench, which is used for anchor plate drilling. The vibration is fierce, and it cannot be used, so the original workbench of the drilling machine is removed, and the numerical control power head 4 is retained for use.

[0021] The power slide 5 is installed with a linear guide rail, and a sliding block is nested on the linear guide rail. The numerical control power head 4 is installed on the linear guide rail through the sliding block. When processing a large diameter anchor plate, the numerical control power head 4 moves outward along the power slide 5, and the small diameter anchor plate moves inward, so that the adjustment range of the numerical control power head 4 can reach 1.8m.

[0022] Further, in order to facilitate drilling, the power slide 5 is arranged on the opposite sides of the periphery of the ground foundation 6. The numerical control power heads 4 on the pair of power slides 5 are radially symmetrical along the axis of the rotary worktable 8. When the power slide 5 is installed on the ground foundation 6 outside the periphery of the rotary worktable 8, the adjustment size of the lowermost drill bit of the multi-shaft drill bit 041 of the numerical control power head 4 after installation is coincided with the size of the anchor plate 2 on the rotary worktable 8.

[0023] Further, in order to improve the stability of drilling, the rotary worktable 8 is provided with a support frame 7, and the support frame 7 comprises at least three annular cylinders. The outer peripheries of the annular cylinders are connected to each other to form an integral body.

[0024] Specifically, in the utility model, the support frame 7 is welded into an integral body by three annular cylinders. The support frame 7 is arranged on the rotary worktable 8 and can support the anchor plate 2 and adapt to the diameter change of the anchor plate 2. The support frame 7 further improves the support strength of the anchor plate 2.

[0025] Further, the upper end of the support frame 7 is sleeved with a water collecting disc 3, and the water collecting disc 3 is communicated with the equipment water tank.

[0026] Specifically, since a large amount of cooling water is required during drilling, the water inlet can use the original water tank of the drilling machine, and the water receiving disc 3 is installed below the front guard plate of the linear guide rail and is sleeved on the outer periphery of the upper end of the support frame 7 for water return. The cooling water flows into the equipment water tank along the water receiving disc 3, ensuring the normal use of the drilling cooling water, and avoiding the equipment accident caused by the cooling water dripping on the lower motor. The water receiving disc 3 is an annular disc body, and an annular groove is formed in the disc body.

[0027] Further, the foundation base 6 includes a foundation pit, the foundation pit is filled with concrete, and the fastening bolts 9 are pre-buried in the concrete, and the rotary workbench 8 and the power sliding table 5 are fixed on the concrete through the fastening bolts 9.

[0028] Specifically, the foundation base 6 serves as the equipment installation base, and when the foundation base 6 is constructed, a foundation pit needs to be excavated first, then the concrete is poured in the foundation pit, and the fastening bolts 9 are pre-buried, and the center axis of the multi-axis drill bit 041 of the numerical control power head 4 and the axis of the rotary workbench 8 are coincided at the same time.

[0029] Further, the support frame 7 is provided with a clamping tool 1 for clamping the anchor plate 2. The anchor plate 2 can be clamped on the clamping tool 1 for easy turnover.
