[0001] This utility model relates to the technical field of coal mine machinery parts, and in particular to a workpiece grooving processing equipment. Background Technology

[0002] When conducting underground water exploration and drainage or coal seam water injection, a high-pressure water injector needs to be connected to the drill rod before the corresponding water injection operation can be carried out. Coal mine drill rods are mining consumable tools and accessories; they are high-efficiency grooved drill rods used in coal seam drilling augers, generally made of high-quality carbon steel, and suitable for use when drilling with coal electric drills.

[0003] When processing coal mine drill rods, general parts processing plants will use a single milling cutter to mill a spiral groove on the outer surface of the coal mine drill rod. However, for special requirements, such as coal mine drill rods that need to be milled with two or more spiral grooves, the processing efficiency of their equipment is low. Utility Model Content

[0004] In view of this, the present invention aims to provide a workpiece grooving processing equipment, which simultaneously mills coal mine drill rods using multiple milling mechanisms equipped with milling cutters, and ensures the stability of the coal mine drill rods during processing through a connecting pipe, thereby improving processing efficiency and work safety.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This embodiment relates to a workpiece grooving processing device, one exemplary structure of which is as follows: Figure 1-6 As shown.

[0022] Overall, such as Figure 1-2 As shown, the workpiece grooving processing equipment includes a machine body 1, a connecting pipe 3 with a connecting interface 2, a first drive unit, a second drive unit, and a guide rail 4 located on one side of the machine body 1, and multiple milling mechanisms with milling cutters 5. The milling mechanisms are fixedly connected to the side wall of the other side of the machine body 1. The connecting interface 2 is used to connect the workpiece 6. The workpiece 6 is a coal mine drill rod, and one end of the drill rod is similar to the tip of a cone and has threads. Therefore, the connecting interface 2 is shaped to fit the end of the coal mine drill rod. The workpiece 6 is threadedly connected to the connecting interface 2 and can be disassembled to ensure the stability of the workpiece 6 during processing. The machine body 1 serves as a carrier for fixing other components.

[0023] During operation, the first drive unit drives the connecting pipe 3 to rotate, and the second drive unit drives the first drive unit to reciprocate along the guide rail 4. The guide rail 4 is parallel to the axial direction of the connecting pipe 3, and the milling mechanism is arranged circumferentially around the connecting pipe 3, with the milling cutter 5 pointing towards the central axis of the workpiece 6. Therefore, the workpiece 6 can be machined simultaneously by the milling cutters 5 of one or more milling mechanisms to mill a spiral groove, meeting the production requirements of the workpiece 6. This ensures the production requirements of the workpiece 6 while also improving processing efficiency.

[0024] It should be noted that when machining a single threaded groove on workpiece 6, only one milling mechanism can be selected to work.

[0025] Preferably, the number of milling mechanisms is three, and they are evenly distributed along the circumference of the connecting pipe 3. Of course, the number of milling mechanisms can also be one, in which case only a single thread-shaped groove can be milled on the outer surface of the workpiece 6.

[0026] In this embodiment, as Figure 3As shown, the milling mechanism includes two connecting plates 7 fixedly connected to the machine body 1, and a working part 8 connected between the two connecting plates 7. The bottom of the working part 8 is rotatably connected to the bottom of the connecting plates 7 via a rotating shaft 9. A travel groove 10 is provided on the connecting plate 7. The working part 8 is connected to the travel groove 10 via fastening bolts 11. The nut end of the fastening bolt 11 is fixedly connected to the working part 8, and the threaded end of the fastening bolt 11 passes through the travel groove 10 and is threadedly connected by a nut. There can be multiple travel grooves 10, and the arc of the travel groove 10 is the arc of the fastening bolt 11 at that point rotating around the rotating shaft 9. By providing the travel groove 10, the working part 8 can rotate around the rotating shaft 9 and be fixed by the travel groove 10 and the fastening bolts 11 within it, thereby adjusting the angle of the working part 8, i.e., adjusting the angle of the milling cutter 5.

[0027] As an example structure of work section 8, such as Figure 4 As shown, the components of the working part 8 are all existing technologies, including a motor and a reducer that drive the milling cutter 5 to rotate. The milling cutter 5 is rotated for milling by the motor driving and the reducer reducing the speed.

[0028] In addition, such as Figure 4 As shown, a mating tooth 12 is provided on a connecting plate 7. A gear 13 adapted to the mating tooth 12 is provided on the working part 8 via a rotating shaft. One end of the rotating shaft is rotatably connected to the working part 8, and the other end is fixedly connected to the gear 13. A hexagonal nut 14 is fixedly connected to the other side of the gear 13. A mounting base is fixedly connected to the working part 8. The rotating shaft is inserted into the mounting base and rotates within the mounting base. When adjusting the angle of the milling cutter 5, because the working part 8 itself is relatively heavy, the hexagonal nut 14 on the gear 13 is turned to make the gear 13 move on the mating tooth 12, which facilitates the lifting or lowering of the working part 8.

[0029] In this embodiment, as Figure 3 and 5As shown, a stabilizing device is provided on the side wall of the machine body 1. The stabilizing device includes a push-pull part 15 and a rotating column 16. The push-pull part 15 is fixedly connected to the side wall of the machine body 1, and the rotating column 16 is rotatably connected to the output end of the push-pull part 15. The rotating column 16 rotates along the axial direction of the workpiece 6. The center of the rotating column 16 is recessed inward along the circumference and has an abutment groove 17. The curvature of the abutment groove 17 matches the curvature of the surface of the workpiece 6. Preferably, there are three stabilizing devices, which are evenly arranged along the circumference of the connecting pipe 3. The push-pull part 15 is preferably an electric push rod or a cylinder. The rotating column 16 can be reciprocated by the push-pull part 15. After the workpiece 6 is on the connecting pipe 3, the push-pull part 15 pushes the rotating column 16 and makes the abutment groove 17 of the rotating column 16 abut against the outer surface of the workpiece 6. During the processing of the workpiece 6, multiple rotating columns 16 are used to hold the workpiece 6 in place, maintaining the stability of the workpiece 6. Because the rotating column 16 rotates along the axial direction of the workpiece 6, it can rotate itself when the connecting pipe 3 carries the workpiece 6 back and forth, facilitating the movement of the workpiece 6. When the workpiece 6 is rotated, because the curvature of the abutment groove 17 matches the curvature of the workpiece 6 surface, the workpiece 6 can rotate itself when the abutment groove 17 abuts against the surface of the workpiece 6. It should be noted that while the abutment groove 17 of the rotating column 16 exerts a certain force when it abuts against the workpiece 6, it does not completely lock the workpiece 6; the workpiece 6 can still rotate when a rotational force is applied.

[0030] In this embodiment, the first drive unit includes a chuck 18, a first motor, and a reducer connected to the first motor. The workpiece 6 is detachably connected to the chuck 18, and the reducer drives the chuck 18 to rotate. The chuck 18 is a common three-jaw chuck on CNC lathes, used to fix the connecting pipe 3. The motor and reducer drive the chuck 18 to rotate, thus driving the connecting pipe 3 on the three-jaw chuck 18 to rotate, thereby rotating the workpiece 6 on the connecting pipe 3 to mill a spiral groove into the workpiece 6.

[0031] Additionally, the second drive unit includes a ball screw 19, and the base 20 of the first drive unit is slidably connected to the guide rail 4, while the base 20 is fixedly connected to the nut of the ball screw 19. When the ball screw 22 rotates, it drives the first drive unit to reciprocate on the guide rail 4 via the nut. The connecting lines of the first drive unit are all installed inside the cable chain. When the first drive unit reciprocates on the guide rail 4, the cable chain moves along with the first drive unit, ensuring the safety of the wiring.

[0032] In this embodiment, as Figure 6As shown, it also includes a conveyor frame, which includes a support plate 21 fixedly connected to the ground and multiple rollers 22. The multiple rollers 22 are arranged along the axial direction of the connecting pipe 3, and the rollers 22 are rotatably mounted on the support plate 21 via a base. The highest point of the surface of the roller 22 is flush with the lowest point of the surface of the connecting pipe 3. This allows the end of the workpiece 6 to be aligned with the connecting port 2 when the workpiece 6 is placed on the roller 22, facilitating the mounting of the workpiece 6. It also allows the workpiece 6 to slide on the roller 22 during processing.

[0033] In addition, multiple sets of stop bar assemblies 23 are provided on the support plate 21, each set including two stop bars fixed to both sides of the support plate 21. When the workpiece 6 is placed on the roller 22, the two stop bars of the stop bar assembly 23 are located on both sides of the workpiece 6 to prevent the workpiece 6 from slipping.

[0034] In this embodiment, a control computer is also included. The control computer controls each component via a PLC, causing each electrical device to operate according to a set program. The control computer and PLC program are existing technologies and will not be described in detail here.

[0035] The working process of this embodiment is as follows: First, the workpiece 6 is placed on the roller 22 on the support plate 21, so that the end of the workpiece 6 is aligned with the interface 2 of the connecting pipe 3 and the workpiece 6 is tightened by thread. The milling cutter 5 of the milling mechanism is started to mill the workpiece 6. The motor and reducer of the first drive unit are started to make the connecting pipe 3 carry the workpiece 6 to rotate through the chuck 18, and the ball screw 19 is used to carry the workpiece 6 back and forth through the first drive unit. The workpiece 6 can rotate while moving back and forth, so that the milling cutter 5 can mill a spiral groove on the outer surface of the workpiece 6. When processing the workpiece 6, the push-pull part 15 is started to make the abutment groove 17 of the rotating column 16 abut against the outer surface of the workpiece 6.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
