[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 This application provides a technical solution: a positioning device for machining the external thread of a drill rod, including a traveling frame 6 and a traveling mechanism 4 mounted on the traveling frame 6. A base plate 10 is slidably mounted on the worktable 3 of the traveling mechanism 4. A vertical support 2 is mounted on the base plate 10. The vertical support 2 is provided with an inclined sliding groove, and a drill rod positioning component is mounted in the sliding groove.

[0020] The traveling mechanism 4 enables the entire device to move on the traveling frame 6, facilitating position adjustment to adapt to different processing needs, making operation more flexible and efficient. The worktable 3 is a sliding platform of the base plate 10, allowing for precise position adjustment in the horizontal direction.

[0021] The worktable 3 is usually equipped with a guide groove or guide rail system to ensure that the base plate 10 can slide smoothly and accurately. The upper surface of the base plate 10 supports the vertical support 2 and the guide slider set below it cooperates with the guide groove on the worktable 3 to achieve precise adjustment in the horizontal direction.

[0022] The vertical support 2 supports the drill rod positioning component and provides a structure with an inclined groove for installing and adjusting the position of the drill rod positioning component. The inclined groove provides a track for the drill rod positioning component to be adjusted along a certain angle. The position and angle of the drill rod can be flexibly adjusted according to its specific shape and processing requirements, improving processing accuracy and efficiency.

[0023] The drill rod positioning component directly contacts and fixes the drill rod, ensuring that the drill rod will not shift or vibrate during processing, thus achieving precise positioning and stable clamping of the drill rod.

[0024] The drill rod positioning component includes an adjusting positioning block 15, an adjusting rotating shaft 16, and a drill rod clamping seat 17. The end of the adjusting positioning block 15 is a square groove, in which the drill rod clamping seat 17 is disposed. The end of the drill rod clamping seat 17 is provided with an arc-shaped groove for clamping the drill rod. The adjusting positioning block 15 is internally threaded to the adjusting rotating shaft 16. The other end of the adjusting rotating shaft 16 is rotatably connected to a coaxial central mounting ring 1 disposed at the center of the vertical support 2.

[0025] The adjusting positioning block 15 serves as a support and adjustment platform for the drill rod clamping seat 17. Through its various components, it enables precise control of the angle and position of the clamping seat. The front end of the adjusting positioning block 15 is provided with a square groove for embedding and fixing the drill rod clamping seat 17. The rear end of the adjusting positioning block 15 is provided with a threaded hole, which forms a threaded connection with the adjusting shaft 16, facilitating rotational adjustment. The adjusting shaft 16 is used to drive the adjusting positioning block 15 to rotate, thereby adjusting the position of the drill rod clamping seat 17 to adapt to the processing requirements of drill rods of different diameters.

[0026] The drill rod clamping seat 17 directly contacts and clamps the tail of the drill rod, preventing displacement or vibration during processing and ensuring machining accuracy. An arc-shaped groove is provided at the end to conform to the shape of the drill rod. Anti-slip pads or rubber layers can be installed inside the arc-shaped groove to enhance clamping force. Furthermore, the clamping seat is removable and replaceable to accommodate drill rods of different diameters.

[0027] The central mounting ring 1 serves as a support point for adjusting the rotating shaft 16, ensuring that it remains coaxial during rotation, thereby improving the stability and adjustment accuracy of the overall device. It is fixed at the geometric center of the vertical support 2.

[0028] The vertical support 2 is also equipped with an anti-sway component.

[0029] Anti-sway components ensure that the chisel is coaxial with the machine tool spindle or machining equipment, avoiding machining errors caused by eccentricity and improving machining accuracy and consistency.

[0030] Specifically, the anti-sway component includes a rotating shaft 14 disposed on the vertical support 2 and a shaft assembly sleeved on the rotating shaft 14. The rotating shaft 14 is symmetrically disposed on both sides of the vertical support 2, and a locking element is threadedly connected to the shaft assembly.

[0031] After the chisel is inserted into the central mounting ring 1, the operator can use the anti-sway assembly to keep the chisel clamping seat 17 coaxial with the machine tool spindle or machining tool. There are two sets of anti-sway assemblies, located at the front and rear positions of the chisel, to prevent it from vibrating and shifting during machining, ensuring machining accuracy. The double-sided symmetrical structure ensures uniform force distribution and improves overall stability.

[0032] Furthermore, a first guide wheel group 8 is provided on the lower surface of the walking mechanism 4, the first guide wheel group 8 is located at the lower end of the walking mechanism 4, and a second guide wheel group 9 is provided around the side wall of the walking mechanism 4.

[0033] The first guide wheel group 8 provides bottom support and guidance, enabling the walking mechanism 4 to slide smoothly along the track or ground, reducing frictional resistance and improving operational stability.

[0034] The second guide wheel group 9 assists in guiding and prevents the walking mechanism 4 from shifting or tilting laterally during operation. It contacts the side of the track to ensure the straightness and stability of the walking path, and plays a role in limiting and stabilizing.

[0035] Furthermore, the workbench 3 is provided with a guide groove, which corresponds to the guide slider provided on the lower surface of the base plate 10, and one side of the central mounting ring 1 is connected to the telescopic adjustment member provided on one side of the walking mechanism 4.

[0036] Furthermore, the telescopic adjustment component includes a positioning plate 19 and an adjustment drive component 5. The positioning plate 19 and the adjustment drive component 5 are connected by fasteners, and the telescopic end of the adjustment drive component 5 is connected to the vertical support 2.

[0037] Furthermore, an upper support frame 11 is provided on the upper surface of the left end of the walking frame 6. The upper support frame 11 is connected to a vertical support seat 13 by fasteners. A limit member 12 is provided at the upper end of the vertical support seat 13.

[0038] The upper support frame 11 provides an installation platform for the vertical support seat 13 and serves as a support and connection to ensure that the limiting component 12 can function effectively. The vertical support seat 13 is the installation base for the limiting component 12 and is vertically installed on the upper support frame 11. It can be fixed by fasteners. The bottom of the vertical support seat 13 is provided with a strip groove for adjusting its position. The position of the vertical support seat 13 can be finely adjusted on the upper support frame 11. The limiting component 12 is used to limit the extreme position of the traveling mechanism 4 to prevent overtravel caused by improper operation or equipment failure, and to ensure the safe operation of the equipment.

[0039] Furthermore, the shaft assembly includes a connector 18 and an intermediate sleeve 20. The annular sleeve on the connector 18 is fitted onto the rotating shaft 14, and the intermediate sleeve 20 is connected to the connector 18 by fasteners.

[0040] Both the connector 18 and the intermediate sleeve 20 are provided with mutually matching steps, and the two are connected by fasteners. The intermediate sleeve 20 can be replaced according to the diameter of the drill rod, improving the flexibility of use.

[0041] Furthermore, a pad 7 is provided on the lower surface of the walking frame 6.

[0042] In use: Select the appropriate drill rod clamping seat 17 according to the diameter of the drill rod to be processed, and replace the appropriate intermediate sleeve 20. Start the walking mechanism 4. Under the action of the first guide wheel group 8 and the second guide wheel group 9, after reaching the designated processing point, turn off the walking motor and activate the braking device. Move the vertical support 2 by adjusting the drive component 5. The guide slider at the bottom of the base plate 10 slides along the guide groove on the worktable 3 to achieve horizontal adjustment. After adjustment, the drive component 5 maintains this state. Rotate the adjusting positioning block 15 through the cooperation of the central mounting ring 1 and the adjusting shaft 16 to align the clamping seat 17 with the drill rod insertion direction. Insert the tail of the drill rod into the arc groove of the drill rod clamping seat 17. Lock the clamping seat to ensure that the drill rod is stable and does not loosen. At the same time, lock the adjusting shaft 16 to prevent deviation during processing. At this time, the rotating connector 18 drives the intermediate sleeve 20 to also be sleeved on the outside of the drill rod to stabilize the drill rod.
