Description

Technical Field

[0001] This utility model relates to the technical field of drilling machine processing devices, and in particular to a high-precision drilling machine processing device. Background Technology

[0002] A drilling machine is a device that uses a drill bit to drill holes in the surface of materials. Drilling is an essential process in the development of mechanical production, used to reinforce and assemble materials. For example, patent (CN210648573U) describes a high-precision metal product drilling method. By setting the placement groove of the workpiece placement table in an inverted trapezoidal shape, it can well accommodate drilling cylindrical metal products of different sizes, improving the machine's flexibility. However, when the drill bit moves downwards in the drilling device, due to the relatively smooth surface of the cylindrical metal product, slippage can easily occur during the downward movement of the drill bit, resulting in a decrease in drilling accuracy. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a high-precision drilling device, including a base, a telescopic rod mounting bracket vertically arranged on the upper end face of the base, an electric telescopic rod and a motor mounting seat mounted on the top of the telescopic rod mounting bracket, a drilling motor for drilling mounted on the motor mounting seat, a bottom support block arranged on the upper end face of the base, a pair of pads arranged on the bottom support block, a cylinder mounting seat mounted on the outer wall of the pads, a first cylinder inserted through the cylinder mounting seat, one end of the first cylinder connected to a clamping plate, the clamping plates clamping the pipe to be drilled, and the other end of the first cylinder connected to an external power source via a wire.

[0006] Preferably, the clamping plate has a double-layer structure, including a rigid bottom layer, and multiple anti-slip rubber strips are bonded to the outer wall of the rigid bottom layer.

[0007] Preferably, a pair of sliding plates are slidably disposed on the top of the support block, and the top of the sliding plates is connected to the pad.

[0008] Preferably, the outer wall of the sliding plate is threaded with a tightening screw, the outer wall of the support block is provided with a sliding groove, and the bottom of the tightening screw passes through the sliding plate and abuts against the inner wall of the sliding groove.

[0009] Preferably, the outer wall of the telescopic rod mounting bracket is provided with a hinge, a rotating rod is rotatably connected to the hinge, a second cylinder is provided on the upper end face of the base, and a collar is rotatably connected to the top of the second cylinder through the hinge, the collar being sleeved on the end of the rotating rod.

[0010] Preferably, the outer wall of the rotating rod is axially provided with an inner clamping block, the outer wall of the inner clamping block is uniformly provided with anti-slip texture, and the inner clamping block is in contact with the inner wall of the pipe to be drilled.

[0011] The high-precision drilling device proposed in this utility model has the following advantages: by setting a first cylinder and a second cylinder, the first cylinder drives multiple clamping plates to clamp and fix the outer wall of the pipe to be drilled, and the second cylinder drives the inner clamping block to move down to fix the inner wall of the pipe to be drilled. The double fixing method can more effectively fix the pipe to be drilled, making the drilling motor more stable during the downward drilling process, effectively improving the drilling accuracy, and the structure is simple and convenient for disassembling and assembling the pipe to be drilled.
