Description

Technical Field

[0001] This application relates to the field of electrical equipment manufacturing, and in particular to an integrated drilling device for long copper busbars. Background Technology

[0002] A copper busbar is a long conductor with a rectangular or chamfered rectangular cross-section, made of copper. It has excellent electrical and thermal conductivity and is widely used as a power transmission and distribution busbar in high and low voltage electrical appliances, switchgear, power distribution equipment and new energy fields. Its length can be determined according to the actual engineering requirements, often reaching several meters or even longer.

[0003] During the assembly of electrical cabinets, multiple mounting holes need to be machined on long copper busbars for connection and fixation. Currently, the common method for drilling long copper busbars is to place them on a work platform and fix both ends using clamps. However, due to the significant radial force and vibration generated by the drill bit during cutting, this method of fixing only the ends is insufficient to provide adequate and effective support for long copper busbars with relatively insufficient rigidity. Especially when the drilling point is far from the clamping end, the middle part of the long copper busbar and the local area of ​​the drilling are prone to vibration due to force, and even slight elastic-plastic deformation. This can not only cause deviation in the drilling position and affect the quality of the hole wall, but in severe cases, it may also cause the drill bit to chip or break, ultimately restricting the processing accuracy, consistency and production yield of long copper busbar products. Summary of the Invention

[0004] The purpose of this application is to address the common practice mentioned in the background art of placing the long copper busbar on a work platform and fixing both ends with a clamp. This method makes the middle part and the local drilling area of ​​the long copper busbar prone to vibration due to stress, and even cause slight elastic-plastic deformation. This not only leads to deviations in the drilling position and affects the quality of the hole wall, but may also cause the drill bit to chip or break in severe cases, ultimately restricting the processing accuracy, consistency and production yield of long copper busbar products. This application provides an integrated drilling equipment for long copper busbars.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: An integrated drilling device for long copper busbars includes a worktable with a transverse base. A transverse threaded rod is rotatably connected to the worktable, passing through and threadedly connected to the transverse base. A vertical arm is fixed to the transverse base, and a support arm is slidably connected to the vertical arm. A vertical threaded rod is rotatably connected to the vertical arm, passing through and threadedly connected to the support arm. A drilling motor is fixed to the support arm, and a pneumatic gripper is installed at the output end of the drilling motor, holding a drill bit. A drive motor is installed at one end of both the transverse and vertical threaded rods. A drilling base is fixed to the worktable, and a telescopic cylinder is fixed to one end of the drilling base. A clamping head is fixed to the telescopic end of the telescopic cylinder, and a clamping block is fixed to the end of the drilling base away from the telescopic cylinder. An auxiliary fixing mechanism is provided on the drilling base, and a moving clamping mechanism is provided between the drilling base and the transverse base. A control console is fixed to one side of the worktable.

[0006] By adopting the above technical solution, the long copper busbar is initially fixed on the drilling base. The auxiliary fixing mechanism clamps and presses the long copper busbar from above, causing it to press against the drilling base. The horizontally moving base drives the corresponding moving clamping mechanism, which moves with the position of the drill bit. After the drill bit stops moving horizontally, the moving clamping mechanism further presses against and fixes the long copper busbar, thus ensuring the stability of the entire long copper busbar during the drilling process. This avoids micro-deformation or even displacement of the long copper busbar caused by drilling, ensuring the stability of the long copper busbar during the drilling process, as well as the drilling accuracy and the production quality of the long copper busbar. At the same time, the moving pressing mechanism further ensures the pressing quality of the long copper busbar.

[0007] Furthermore, the auxiliary fixing mechanism includes several support rods mounted on the drilling base. One end of each support rod is fixed to a fixing rod, and the end of the support rod away from the fixing rod passes through the drilling base. The drilling base is fixed with a rotary clamping cylinder corresponding to the support rod. The rotating retracting end of the rotary clamping cylinder is fixedly connected to the support rod, and a limit assembly is provided between adjacent rotary clamping cylinders.

[0008] By adopting the above technical solution, the rotary clamping cylinder is instructed to rotate, causing the support rod to rotate the fixed rod towards the top of the long copper busbar and move towards the long copper busbar. This allows the fixed rod to firmly contact the long copper busbar placed on the drilling base, thereby ensuring the stability of the entire long copper busbar during the drilling process and preventing the drilling from causing micro-deformation or even displacement of the long copper busbar, thus ensuring the stability of the long copper busbar during the drilling process.

[0009] Furthermore, the limiting component includes a limiting ring one disposed between adjacent rotary clamping cylinders, and a limiting ring two fixed on one side of the rotary clamping cylinder.

[0010] By adopting the above technical solution and setting limit ring one and limit ring two, the air pipes of the rotary clamping cylinder are sorted out, thereby reducing the possibility that the numerous and messy air pipes of the rotary clamping cylinder may affect the movement of the structure.

[0011] Furthermore, the movable clamping mechanism includes a movable seat mounted on the drilling base. The movable seat is U-shaped, and its two ends are slidably connected to the two sides of the drilling base. A second fixed rod is provided at one end of the movable seat, and a third fixed rod is provided at the end of the movable seat away from the second fixed rod. Movable components are provided between the second fixed rod, the third fixed rod, and the movable seat. A synchronous rotation component is provided on the movable seat. A telescopic component corresponding to the third fixed rod is provided on one side of the movable seat. A connecting seat is fixedly provided at the end of the movable seat near the transverse base, and the connecting seat is fixedly connected to the transverse base.

[0012] By adopting the above technical solution, the movable seat can slide on the drilling base, the movable component drives the fixed rod two and fixed rod three to move, the synchronous rotation component ensures that the two movable components move synchronously, and the telescopic component further adjusts the position of the fixed rod three, so that after the drill bit stops moving laterally, the fixed rod two and fixed rod three can further resist and fix the long copper busbar, ensuring the stability of the long copper busbar during the drilling process.

[0013] Furthermore, the movable component includes a clamping threaded rod rotatably connected to the movable seat, a limit rod is provided on one side of the clamping threaded rod, the limit rod is fixedly connected to the movable seat, a limit block is fixed at the end of the limit rod away from the movable seat, a second fixed rod is threadedly connected to the corresponding clamping threaded rod, and the second fixed rod is slidably connected to the limit rod.

[0014] By adopting the above technical solution, rotating the clamping threaded rod causes the fixed rod two to be threadedly connected to the clamping threaded rod, and under the limiting action of the limiting rod and the limiting block, the fixed rod two will move along the length direction of the clamping threaded rod, thereby realizing the position adjustment of the fixed rod two and the fixed rod three, so as to better fix the long copper busbar against the ground.

[0015] Furthermore, the synchronous rotation assembly includes two bevel gears 1 symmetrically rotatably connected within the movable seat. The clamping threaded rod passes through the movable seat and is fixedly connected to the corresponding bevel gear 1. A bevel gear 2 is meshed on the bevel gear 1. The bevel gear 2 is rotatably connected to the movable seat. A synchronous motor is fixed to one end of the movable seat. A drive shaft is fixed to the output end of the synchronous motor. The drive shaft passes through the movable seat and is fixedly connected to the two bevel gears 2.

[0016] By adopting the above technical solution, the drive shaft drives the two bevel gears to rotate synchronously, the bevel gears drive the bevel gears that mesh with them to rotate, and the bevel gears drive the corresponding clamping threaded rods to rotate, thereby realizing the synchronous rotation of the two clamping threaded rods, ensuring that the fixed rods 2 and 3 can move synchronously, and improving the action accuracy of the moving clamping mechanism.

[0017] Furthermore, the telescopic assembly includes a support base fixed on the connecting seat, an electric telescopic rod fixed on the support base, a fixing block slidably connected to the fixing rod three, a clamping threaded rod on the movable seat near the fixing rod three being threadedly connected to the fixing block, and a limiting rod passing through the fixing block and slidably connected to the fixing block.

[0018] By adopting the above technical solution, the electric telescopic rod is activated, and the fixed rod three moves on the fixed block, thereby achieving further adjustment of the position of the fixed rod three in order to better fix the long copper busbar against the block.

[0019] Furthermore, the telescopic end of the electric telescopic rod is fixed with a sliding rail, and a sliding block is slidably connected on the sliding rail, the sliding block being fixedly connected to the fixed rod.

[0020] By adopting the above technical solution, the sliding rail and sliding block provide guidance for the movement of the fixed rod three, so that the fixed rod three will not drive the electric telescopic rod during the clamping action.

[0021] Furthermore, a laser rangefinder is fixed on the movable base, and the output end of the laser rangefinder is perpendicular to the moving direction of the movable base.

[0022] By adopting the above technical solution, the distance between the moving base and the target object is determined by calculating the round-trip time of the laser. The target object is the position of the upper side of the long copper busbar and the position of the support rod. This allows for the determination of whether the first fixed rod and the third fixed rod overlap, thus ensuring a quick and accurate determination of whether the first fixed rod and the third fixed rod overlap based on the actual situation.

[0023] In summary, this application includes at least one of the following beneficial effects; 1. In this application, after the long copper busbar is placed on the drilling base, the control system in the control console commands the rotary clamping cylinder to operate. The rotating and retracting end of the cylinder drives the support rod, causing the support rod to rotate and move the first fixed rod upwards toward the long copper busbar. This ensures that the first fixed rod firmly abuts against the long copper busbar placed on the drilling base. Simultaneously, during drilling, the synchronous rotation component drives the moving component, which in turn drives the second and third fixed rods. The second and third fixed rods clamp the long copper busbar from above, further tightening it. This achieves stability of the entire long copper busbar during drilling, preventing micro-deformation or even displacement caused by drilling. This ensures the stability of the long copper busbar during drilling, guarantees drilling accuracy, ensures the production quality of the long copper busbar, and further guarantees the clamping quality of the long copper busbar.

[0024] 2. In this application, by fixing an upper limit ring 1 and a limit ring 2 at the bottom of the drilling base, when connecting the air inlet and outlet pipes of the rotary clamping cylinder to the rotary clamping cylinder, the air inlet and outlet pipes first pass through the limit ring 1, and then through the limit ring 2, and continue to pass through the limit ring 2 until the air inlet and outlet pipes are neatly arranged at the bottom of the drilling base. This achieves the purpose of reducing the possibility of a large number of air pipes of the rotary clamping cylinder and messy placement affecting the movement of the structure.

[0025] 3. In this application, when the horizontal base moves the second and third fixed rods, if the laser rangefinder detects that the third fixed rod is in conflict with the position of the first fixed rod in the middle, the control system of the control console will prioritize instructing the electric telescopic rod to retract, so that the third fixed rod avoids the pressing area of ​​the first fixed rod, thereby achieving the purpose of ensuring that the multiple fixing mechanisms do not interfere with each other and work together.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0029] This application discloses an integrated drilling device for long copper busbars.

[0030] Reference Figure 1 , Figure 2 and Figure 3 An integrated drilling device for long copper busbars includes a worktable 1, a transverse base 8 on the worktable 1, a transverse threaded rod rotatably connected to the worktable 1, the transverse threaded rod passing through the transverse base 8 and threadedly connected to the transverse base 8, a vertical arm 9 fixed on the transverse base 8, a support arm 10 slidably connected to the vertical arm 9, a vertical threaded rod rotatably connected to the vertical arm 9, the vertical threaded rod passing through the support arm 10 and threadedly connected to the support arm 10, a drilling motor 2 fixed on the support arm 10, and a drilling motor 2 having a [missing information - likely a device name or function] installed at its output end. A pneumatic gripper 3 holds a drill bit 4. A drive motor is installed at one end of both the horizontal and vertical threaded rods. A drilling base 5 is fixed on the worktable 1. A telescopic cylinder 11 is fixed at one end of the drilling base 5. A clamping head 12 is fixed at the telescopic end of the telescopic cylinder 11. A clamping block 13 is fixed at the end of the drilling base 5 away from the telescopic cylinder 11. An auxiliary fixing mechanism 6 is provided on the drilling base 5. A moving clamping mechanism 7 is provided between the drilling base 5 and the horizontal base 8. A control console 14 is fixed on one side of the worktable 1.

[0031] When drilling is required on a long copper busbar, the long copper busbar is placed on the drilling base 5, with one end abutting against the clamping block 13. The telescopic cylinder 11 is controlled by the control console 14, causing the telescopic cylinder 11 to move the clamping head 12 to abut against the other end of the long copper busbar, initially fixing the long copper busbar to the drilling base 5. Then, the auxiliary fixing mechanism 6 is used to fix the long copper busbar from the side, squeezing and clamping it from above, causing the long copper busbar to abut against the drilling base 5. After preparation, the horizontal and vertical threaded rods rotate under the drive of their respective drive motors, driving the horizontal base 8 and support arm 10 to perform precise two-dimensional positioning, aligning the drill bit 4 with the preset drilling position. The horizontal base 8 then drives the corresponding moving clamping mechanism. Following the position movement of drill bit 4, after drill bit 4 stops moving laterally, the moving clamping mechanism further resists and fixes the long copper busbar, improving the stability of the long copper busbar when drill bit 4 drills holes in it. By setting an auxiliary fixing mechanism 6 on the placement base, when the long copper busbar is fixed at both ends, the auxiliary fixing mechanism 6 further fixes the long copper busbar from above. At the same time, the moving clamping mechanism 7 moves with the lateral base 8 and follows drill bit 4, thus ensuring the stability of the entire long copper busbar during drilling. This avoids micro-deformation or even displacement of the long copper busbar caused by drilling, ensuring the stability of the long copper busbar during drilling, as well as the drilling accuracy and production quality of the long copper busbar. At the same time, the moving pressing mechanism further ensures the pressing quality of the long copper busbar.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The auxiliary fixing mechanism 6 includes several support rods 62 mounted on the drilling base 5. One end of each support rod 62 is fixed to a fixing rod 61, and the end of the support rod 62 away from the fixing rod 61 passes through the drilling base 5. The drilling base 5 is fixed with a rotary clamping cylinder 63 corresponding to the support rod 62. The rotating retracting end of the rotary clamping cylinder 63 is fixedly connected to the support rod 62, and a limit component 64 is provided between adjacent rotary clamping cylinders 63.

[0033] After the long copper busbar is placed on the drilling base 5, the control system in the control console 14 commands the rotary clamping cylinder 63 to operate. Its rotating and retracting end drives the support rod 62, causing the support rod 62 to rotate the fixing rod 61 towards the top of the long copper busbar and move towards it. This ensures that the fixing rod 61 firmly abuts against the long copper busbar placed on the drilling base 5. By placing the long copper busbar on the drilling base 5 and fixing both ends with the clamping head 12 and clamping block 13, the rotary clamping cylinder 63 drives the fixing rod 61 to rotate above the long copper busbar, allowing the fixing rod 61 to abut against it. This ensures the stability of the entire long copper busbar during the drilling process, preventing the drilling from causing micro-deformation or even displacement of the long copper busbar, thus guaranteeing its stability during drilling.

[0034] Reference Figure 3 and Figure 4 The limiting component 64 includes a limiting ring 641 disposed between adjacent rotary clamping cylinders 63, and a limiting ring 642 fixed on one side of the rotary clamping cylinder 63.

[0035] Upper limit ring 1 641 and limit ring 2 642 are fixed at the bottom of the drilling base 5. When connecting the air inlet and outlet pipes of the rotary clamping cylinder 63 to the rotary clamping cylinder 63, the air inlet and outlet pipes first pass through the limit ring 1 641, and then through the limit ring 2 642, and continue to pass through the limit ring 2 642 until the air inlet and outlet pipes are neatly arranged at the bottom of the drilling base 5. By fixing the corresponding limit ring 1 641 and limit ring 2 642 on the drilling base 5, the air inlet and outlet pipes of the rotary clamping cylinder 63 can be organized by the limit ring 1 641 and limit ring 2 642, thereby reducing the possibility of too many air pipes of the rotary clamping cylinder 63 and messy placement affecting the movement of the structure.

[0036] Reference Figure 3 , Figure 5 and Figure 6 The movable clamping mechanism 7 includes a movable seat 71 mounted on the drilling base 5. The movable seat 71 is U-shaped, and its two ends are slidably connected to the two sides of the drilling base 5. A second fixed rod 72 is mounted on one end of the movable seat 71, and a third fixed rod 73 is mounted on the other end of the movable seat 71 away from the second fixed rod 72. Movable components 74 are mounted between the second fixed rod 72, the third fixed rod 73 and the movable seat 71. A synchronous rotation component 75 is mounted on the movable seat 71. A telescopic component 76 corresponding to the third fixed rod 73 is mounted on one side of the movable seat 71. A connecting seat 77 is fixedly mounted on the end of the movable seat 71 near the transverse base 8, and the connecting seat 77 is fixedly connected to the transverse base 8.

[0037] When the transverse base 8 moves, it drives the connecting seat 77, which in turn drives the moving seat 71. The moving seat 71 then drives the moving component 74, which in turn drives the fixed rods 72 and 73 to move simultaneously. When the transverse base 8 stops moving, the synchronous rotation component 75 drives the moving component 74, which in turn drives the fixed rods 72 and 73. This causes the fixed rods 72 and 73 to clamp the long copper busbar from above, further tightening the clamps. The movement of the fixed rods 72 and 73 continues until the fixed rods 73 and 74 are fully clamped. When positions 1 coincide, the telescopic component 76 drives the fixed rod 3 73 to move towards the transverse base 8, allowing the fixed rod 3 73 to disengage from the clamping range. The transverse base 8 then drives the connecting seat 77, which in turn drives the moving seat 71. This causes the fixed rods 2 72 and 3 73 on the moving seat 71 to move accordingly, further clamping the drill bit 4 at the drilling position. This further improves the quality of the long copper busbar fixation and reduces the possibility of the long copper busbar shifting and affecting the drilling quality.

[0038] Reference Figure 3 , Figure 5 and Figure 6 The movable component 74 includes a clamping threaded rod 741 rotatably connected to the movable seat 71. A limit rod 742 is provided on one side of the clamping threaded rod 741. The limit rod 742 is fixedly connected to the movable seat 71. A limit block 743 is fixed at the end of the limit rod 742 away from the movable seat 71. A second fixed rod 72 is threadedly connected to the corresponding clamping threaded rod 741. The second fixed rod 72 is slidably connected to the limit rod 742.

[0039] When the synchronous rotation assembly 75 drives the clamping threaded rod 741 to rotate, the limiting rod 742 and the limiting block 743 can restrict the rotation of the second fixed rod 72 and the third fixed rod 73, so that the second fixed rod 72 and the third fixed rod 73 can only move along the axial direction of the clamping threaded rod 741, thereby achieving the clamping action of the long copper busbar. When it is necessary to release the long copper busbar, the synchronous rotation assembly 75 rotates in the opposite direction to clamp the threaded rod 741, and the second fixed rod 72 moves in the opposite direction to release the clamping of the long copper busbar. By allowing the second fixed rod 72 and the third fixed rod 73 to move on the clamping telescopic rod, it is convenient to move the second fixed rod 72 and the third fixed rod 73, so that the second fixed rod 72 and the third fixed rod 73 can abut against the long copper busbar, thereby improving the accuracy and stability of the long copper busbar fixation.

[0040] Reference Figure 3 , Figure 5 and Figure 6The synchronous rotation assembly 75 includes two bevel gears 751 symmetrically rotatably connected within the movable seat 71. A clamping threaded rod 741 passes through the movable seat 71 and is fixedly connected to the corresponding bevel gear 751. A bevel gear 752 is meshed on the bevel gear 751 and is rotatably connected to the movable seat 71. A synchronous motor 754 is fixed to one end of the movable seat 71. A drive shaft 753 is fixed to the output end of the synchronous motor 754. The drive shaft 753 passes through the movable seat 71 and is fixedly connected to the two bevel gears 752.

[0041] When the synchronous motor 754 starts, the drive shaft 753 drives the two bevel gears 752 to rotate synchronously. Since the bevel gears 752 are meshed with the bevel gears 751, the bevel gears 751 will rotate accordingly, thereby driving the clamping threaded rod 741 fixed to the bevel gears 751 to rotate. By controlling the forward and reverse rotation of the synchronous motor 754, the forward and reverse rotation of the clamping threaded rod 741 can be achieved, thereby controlling the clamping and loosening actions of the fixing rods 72 and 73. When drilling is required on the long copper busbar, the synchronous motor 754 starts, driving the clamping threaded rod 741 to rotate through the synchronous rotation assembly 75, causing the fixing rods 741 to rotate. The second fixing rod 72 and the third fixing rod 73 move simultaneously towards the long copper busbar until they are firmly pressed against it, thus achieving a stable clamping of the long copper busbar. After drilling is completed, the synchronous motor 754 rotates in the opposite direction, causing the second fixing rod 72 and the third fixing rod 73 to release the long copper busbar, facilitating its removal and the next drilling operation. By using the drive shaft 753 to drive the two bevel gears 752, which in turn drive the first bevel gear 751 to rotate, the two clamping threaded rods 741 remain synchronized, thereby ensuring that the second fixing rod 72 and the third fixing rod 73 can move simultaneously and at the same speed, improving the stability and accuracy of the long copper busbar fixing.

[0042] Reference Figure 3 , Figure 5 and Figure 6 The telescopic assembly 76 includes a support seat 761 fixed on the connecting seat 77, an electric telescopic rod 762 fixed on the support seat 761, a fixed block 763 slidably connected to the fixed rod 73, a clamping threaded rod 741 on the movable seat 71 near the fixed rod 73 being threadedly connected to the fixed block 763, and a limiting rod 742 passing through the fixed block 763 and slidably connected to the fixed block 763.

[0043] When the position of the fixed rod 73 needs to be adjusted, the electric telescopic rod 762 is activated, and its telescopic end drives the fixed rod 73. The fixed rod 73 moves on the fixed block 763. Under the restriction of the clamping threaded rod 741 and the limiting rod 742 connected to the fixed block 763, the fixed rod 73 remains stable during movement and will not deflect. By controlling the electric telescopic rod 762, the position of the fixed rod 73 can be finely adjusted, so that when the fixed rod 73 and the fixed rod 61 overlap, the clamping of the fixed rod 73 can be canceled, reducing the possibility of overlap and conflict between the fixed rod 61 and the fixed rod 73.

[0044] Reference Figure 5 and Figure 6 The telescopic end of the electric telescopic rod 762 is fixed with a sliding rail 765, and a sliding block 764 is slidably connected to the sliding rail 765. The sliding block 764 is fixedly connected to the fixed rod 73. When the electric telescopic rod 762 is started, its telescopic end drives the sliding rail 765 to move linearly, and the sliding block 764 on the sliding rail 765 moves accordingly. Since the sliding block 764 is fixedly connected to the fixed rod 73, the fixed rod 73 also moves with the sliding block 764. When the fixed rod 73 clamps the long copper busbar, the fixed block 763 drives the fixed rod 73, and the fixed rod 73 drives the sliding block 764 to move in the sliding rail 765. By using the sliding block 764 and the sliding rail 765 to connect the fixed rod 73 and the telescopic end of the electric telescopic rod 762, the fixed rod 73 can move more smoothly during movement, while reducing the possibility of conflict between the clamping and fixing of the fixed rod 73 and the electric telescopic rod 762.

[0045] Reference Figure 5 and Figure 6 A laser rangefinder 766 is fixed on the movable base 71, and the output of the laser rangefinder 766 is perpendicular to the moving direction of the movable base 71. During the movement of the movable base 71, the laser rangefinder 766 emits a laser beam in real time and receives the reflected signal. By calculating the round-trip time of the laser, the distance between the movable base 71 and the target object is determined. This target object is the position of the upper side of the long copper busbar and the position of the support rod 62. Based on the distance information fed back by the laser rangefinder 766, the control system can accurately determine whether the fixed rod 1 61 and the fixed rod 3 73 overlap, thereby ensuring a fast and accurate determination of whether the fixed rod 1 61 and the fixed rod 3 73 overlap according to the actual situation.

[0046] Working principle: The control console 14 is electrically connected to each motor, cylinder, and sensor to control the automated operation of the entire equipment. First, the workpiece is clamped and initially fixed. The long copper busbar is placed on the drilling base 5, with one end pressed against the fixed clamping block 13. The telescopic cylinder 11 is activated, pushing its front clamping head 12 forward until the long copper busbar is pressed tightly from the other end, completing the initial fixation of the workpiece in the length direction. Subsequently, several rotary clamping cylinders 63 operate simultaneously. Their rotating retracting ends push the support rod 62 upward and rotate, causing the fixing rod 61, fixedly connected to the top of the support rod 62, to steadily press down on the middle of the long copper busbar from above, preventing it from vibrating due to its own weight or processing stress.

[0047] According to the preset drilling position, the horizontal and vertical drive motors are started. Through the transmission of the horizontal and vertical threaded rods, the entire drilling motor unit 2 and the movable clamping mechanism 7 fixed thereto are driven to the target hole position. During this process, the moving seat 71 slides accordingly. After positioning is completed, the synchronous motor 754 is started, which drives the two bevel gears 752 to rotate synchronously through the drive shaft 753. The bevel gear 751 meshing with it rotates accordingly, thereby driving the two clamping threaded rods 741 to rotate synchronously. Under the constraint of the limit rod 742, the fixed rods 72 and 73 cannot rotate and can only move synchronously towards each other, pressing the workpiece tightly from both sides above, providing local reinforcement and fixation for the upcoming drilling operation. During this process, if the laser rangefinder 766 detects that the fixed rod 73 conflicts with the position of the fixed rod 61 in the middle, the control system of the control console 14 will prioritize instructing the electric telescopic rod 762 to retract, so that the fixed rod 73 avoids the pressing area of ​​the fixed rod 61, ensuring that the multiple fixing mechanisms do not interfere with each other and work together.

[0048] After all the fixed points are confirmed to be clamped in place, the drilling motor 2 starts, driving the drill bit 4, which is tightly held by the pneumatic gripper 3, to rotate at high speed and drill. After drilling is completed, the drilling motor 2 stops, the drill bit 4 retracts, and then the synchronous motor 754 reverses, causing the fixing rod 2 72 and fixing rod 3 73 to loosen and return to their original positions. Then, the rotary clamping cylinder 63 retracts, causing the fixing rod 1 61 to rotate and lift, releasing the pressure on the middle of the workpiece. Finally, the telescopic cylinder 11 retracts, releasing the pressure on the end of the workpiece, and the long copper busbar that has been drilled can be removed. All the actuators of the equipment reset, ready for the next work cycle.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
