[0002] SMC solid insulation workpieces have high mechanical strength, flame retardancy, and leakage resistance second only to UPM203; high arc resistance, dielectric strength and voltage resistance; low water absorption, stable dimensions, small warping, etc. SMC solid insulation workpieces are mainly used in various insulating partitions of high, medium and low voltage switchgear. Large SMC solid insulation workpieces need to be tapped during the processing process. Large SMC solid insulation workpieces are large in size and are not convenient for movement and adjustment due to site restrictions. However, the existing tapping device has a limited moving stroke and cannot perform tapping operations on multiple tapping positions of large SMC solid insulation workpieces, thereby failing to realize tapping operations on large SMC solid insulation workpieces.

[0003] The existing Chinese patent CN220112495U is a mobile tapping device. When solving the above problems, no fixing mechanism is designed on the slide rail and the slide rail. This means that during use, in order to facilitate observation of the tapping position through the positioning hole, the operator needs to carry the electric drill by hand and keep the electric drill at a specified height before performing the tapping operation. During this process, an upward force needs to be applied to the electric drill before tapping to keep the electric drill at the specified height. This operation method is extremely inconvenient.

[0033] Working principle: The utility model is a tapping device. During use, the tapping position of the large SMC solid insulation workpiece is preliminarily positioned through the positioning hole 2 set through the bottom plate 1. During tapping, the positioning hole 2 is convenient for the staff to observe the relative position of the drill bit of the hand drill 6 and the tapping position of the large insulation material workpiece, and the tapping position is adjusted by adjusting the movable bottom plate 1 so that the drill bit of the hand drill 6 is located above the tapping position, thereby ensuring that the drill bit of the hand drill 6 can perform tapping operations at the corresponding tapping position, which has the advantages of ensuring positioning accuracy and facilitating regulation.

[0034] During the above operation, since the block 17 is engaged with the rack 16 and the movable frame 4 is fixed, the hand drill 6 is fixed at a specified height, so that it is convenient to observe the tapping position through the positioning hole 2. Compared with the prior art, the device does not require the staff to give the hand drill 6 an upward force to make it at the specified height, and the device is simple and labor-saving to operate;

[0035] During the tapping operation, the operator holds the hand drill 6 with his right hand and starts it, the hand drill 6 drives the drill bit to rotate, and then pushes the push plate 22 to move to the right with his left hand, and at the same time the spring 21 is compressed, the push plate 22 drives the movable rod 18 to move in the inner cavity of the perforation 20, and the movable rod 18 drives the clamping block 17 to move away from the rack 16, thereby unlocking the fixation of the movable frame 4, and then moves the hand drill 6 downward, and the drill bit of the hand drill 6 passes through the positioning hole 2 to tap the workpiece;

[0036] When the electric drill 6 needs to be replaced or disassembled, the crank wheel 14 is rotated, and the crank wheel 14 drives the threaded rod 12 to rotate in the inner cavity of the nut 11 and the bearing 13. The nut 11 drives the locking frame 8 to move forward relative to the threaded rod 12, and the locking frame 8 moves in the inner cavity of the limit groove 9. The locking frame 8 moves away from the electric drill 6, thereby releasing the fixation of the electric drill 6, and then the electric drill 6 is moved upward to complete the disassembly. During installation, it is only necessary to place the electric drill 6 in the inner cavity of the mounting frame 5, and then rotate the crank wheel 14 to move the locking frame 8 to the rear side until the buffer pad 10 and the electric drill 6 are in contact with each other to complete the installation. The operation is simple and convenient for repairing or replacing multiple electric drills 6.
