As shown in Fig. 1-2, a boring device for a radial drilling machine includes a tool holder 1 and a tool 6. The tool holder 1 is detachably fixed to the drill arm of the radial drilling machine, and the tool 6 can be installed on the basis of the existing drilling machine to realize the boring function. The drill arm can bore the workpiece to be processed when it moves downward, and the tool 6 extends radially into the tool holder 1 and slides radially along the tool holder 1, so that the position of the tool 6 can be adjusted according to actual needs, ensuring that the boring device can adjust the extension length according to actual needs, thereby meeting the boring processing of different hole diameters. Correspondingly, a mounting hole corresponding to the tool 6 is provided on the drill arm of the radial drilling machine, and the mounting hole passes through the drill arm of the radial drilling machine, so that the tool 6 can slide radially.

The main body of the tool 6 is cylindrical, and its outer diameter is matched with the diameter of the mounting hole and the adjustment hole 5. A cutter head 7 is provided at one end of the tool 6, and an alloy blade body 8 is provided on the cutter head 7, so that the workpiece to be bored can be cut. In actual use, the outer peripheral surface of the tool holder 1 is circular, and the inner peripheral surface is matched with the outer peripheral surface of the drill arm of the radial drilling machine. The cutter head 7 extends out of the outer peripheral surface of the tool holder 1, so that the hole wall of the workpiece to be processed can be processed by rotation. An adjusting bolt 3 corresponding to the other end of the tool 6 is threadedly assembled on the tool holder 1. The adjusting bolt 3 is located at the end away from the cutter head 7, so that it extends into or contacts the end of the tool 6 away from the cutter head 7 behind the bed drill arm. In this way, the length of the cutter head 7 extending out of the outer peripheral surface of the tool holder 1 can be adjusted by adjusting the bolt 3 to achieve the processing of boring holes with different hole diameters.

In addition, a locking bolt 4 is provided on the tool holder 1, the locking bolt 4 is threadedly connected to the tool holder 1, and extends into the tool holder 1 along the radial direction of the tool 6. After extending into the tool holder 1, it is pressed against the outer wall of the tool 6, thereby fixing the tool 6 and ensuring the stability of the tool 6 during the boring process.

In an optional embodiment, an adjustment hole 5 corresponding to the tool 6 is provided on the tool holder 1. The adjustment hole 5 is concentrically distributed with the mounting hole, and the inner diameters of the two are the same, so as to ensure that the prop can slide and be pushed smoothly between the prop and the rotating arm. The mounting hole is a multi-faceted hole externally connected to the adjustment hole 5, and can be specifically a hexagonal structure. The end of the tool 6 away from the tool head 7 is a multi-faceted structure, and specifically a hexagonal structure adapted thereto. The hexagonal structure ensures that the angle of the blade of the prop is constant, thereby ensuring the stability of the tool 6 during adjustment and boring.

In an optional embodiment, the tool holder 1 is an annular structure, specifically made of stainless steel, so that it can be clamped on the rotating arm of the radial drilling machine. The inner diameter of the tool holder 1 is adapted to the outer diameter of the rotating arm. At least one locking bolt 4 is provided on the upper end face and the lower end face of the tool holder 1. The screw hole of the locking bolt 4 is connected with the adjustment hole 5 along the radial direction, so that it can be extended into the adjustment hole 5. The specific number of locking bolts 4 can be set according to the actual thickness of the tool holder 1 to meet the fixing props, so that it can be locked on both sides of the tool 6. The force stability is ensured by multiple locking bolts 4 to improve the fixing effect.

The locking bolt 4 does not extend out of the outer peripheral surface of the tool holder 1 in the radial direction and may be a countersunk bolt.

In an optional embodiment, the tool holder 1 is an annular structure, which is formed by splicing two equally divided parts along its radial direction. The two equally divided parts are in the shape of tiles and can be embraced on the outside of the drill arm through splicing. One of the equally divided parts is provided with a clearance hole 2 on both sides, and the other equally divided part is provided with threaded holes corresponding to the clearance holes 2 on both sides. The fixing bolt is inserted into the clearance hole 2 and then threadedly connected to the other equally divided part. The two equally divided parts can be fixed by tightening the fixing bolt, and the auxiliary tool 6 ensures that the tool holder 1 has sufficient stability.

In this embodiment, the fixing bolts and the adjusting bolts are all countersunk bolts, so as to ensure that they will not protrude from the outer peripheral surface of the prop after installation, and ensure that no movement interference will occur during the boring process.

In an optional embodiment, a mounting surface corresponding to the rotation direction of the drill arm of the radial drilling machine is provided on the cutter head 7 of the tool 6. The mounting surface is a flat surface, and a step corresponding to the alloy blade body 8 is provided on the side of the flat surface extending out of the tool holder 1, so that the alloy blade body 8 can be detachably connected to the mounting surface.

The alloy blade body 8 is fixed on the mounting surface by welding and/or screw connection, so that the alloy blade body 8 can be fully fixed. The diameter of the outer peripheral surface of the alloy blade body 8 is greater than the diameter of the outer peripheral surface of the cutter head 7.

In this embodiment, a fixing seat corresponding to the workpiece to be bored is provided on the working surface of the radial drilling machine. The fixing seat fixes the workpiece to be bored by bolts and a pressure plate. The bolts are connected to the fixing seat along the longitudinal thread. The pressure plate is tightened to press the workpiece to be bored to fix it.

The working surface of the radial drilling machine is provided with multiple dovetail grooves, and the fixing seat is provided with screw holes corresponding to the dovetail grooves. One end of the positioning bolt is slidably assembled in the dovetail groove through a slider, and the other end passes through the screw hole and is fixed with a nut, thereby fixing the fixing seat.

This application adds a self-made tool holder and tool to the original drill arm to realize the boring function. There are adjustment bolts on the side of the tool holder to adjust the cutting range of the cutter head. The on-site boring range is 90-110mm. The tool holder size can be made according to needs to realize the boring function of other specifications of apertures, thereby achieving a dual-purpose effect of one machine.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
