Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to drilling devices. Background Technology

[0002] High conductivity cathode steel rods are a special material used in electrolytic cells. By drilling holes in the steel rods using a drilling device and filling the inside of the steel rods with highly conductive materials, the conductivity of the cathode steel rods can be significantly improved, and the resistivity and voltage drop of the cathode system can be reduced.

[0003] When drilling a cathode steel rod using a drilling device, the cathode steel rod is placed on the drilling device and fixed with a clamp. Then, the drill bit drills the steel plate while the steel plate is brought close to the drill bit. During the processing, if different thicknesses or different positions of the steel rod are being processed, the height of the clamping block needs to be adjusted. When adjusting the position, it is inconvenient to align the specified drilling position with the position of the drill bit, which leads to deviations in the drilling position and affects the drilling effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when processing steel bars of different thicknesses or at different positions, it is necessary to adjust the height of the clamping block during the processing. When adjusting the position, it is inconvenient to align the specified drilling position with the drill bit, which leads to deviation in the drilling position and affects the drilling effect. Therefore, a drilling device for processing high conductivity cathode steel bars is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drilling device for processing high conductivity cathode steel rods, comprising a frame, a slide, and a clamping mechanism. The frame is placed on the ground to support the entire device. A servo motor and a lead screw driven by the servo motor are provided on the outer surface of the frame. The servo motor drives the lead screw to rotate, controlling the movement of the slide on the outer surface of the frame. The clamping mechanism is installed on the outer surface of the slide and includes:

[0006] The support plate is fixed to the top of the slide to support the entire clamping mechanism.

[0007] Hydraulic rods are installed on one side of the frame plate to control the movement of the lifting seat;

[0008] The lifting seat is fixed to one side of the output end of the hydraulic rod. The lifting seat is controlled to slide up and down on one side of the frame plate by operating the hydraulic rod. The outer surface of the lifting seat is provided with a positioning device that can help position the angle between the cathode rod and the drill rod fixed on one side of the lifting seat.

[0009] Electric push rods and clamping blocks: Two electric push rods are installed on both sides of the lifting seat, and the clamping blocks are fixed on one side of the output rod of the electric push rods. By operating the electric push rods, the clamping blocks can be controlled to move on one side of the lifting seat to clamp the cathode rod.

[0010] It also includes a drive motor and a drill rod. The drive motor is mounted on the outer surface of the frame at the end away from the servo motor, and the drill rod is mounted on the output side of the drive motor. The drive motor drives the drill rod to rotate.

[0011] The effect achieved by the above components is as follows: When using the drilling device, one end of the cathode rod is pressed against the outer surface of the lifting seat. The electric push rods on both sides of the lifting seat are extended to control the two clamping blocks to move in the same direction, so that the clamping blocks clamp and fix the cathode rod to one side of the lifting seat. Then, the servo motor at one end of the frame drives the lead screw to rotate inside the frame, so that the slide moves threadedly on the outer surface of the lead screw and slides on the outer surface of the frame towards the drill rod. One end of the cathode rod is pressed against one end of the drill rod. The drive motor is operated to drive the drill rod to rotate and the slide moves slowly towards the drill rod to drill a hole in the cathode rod. After drilling is completed, the servo motor is operated to control the lead screw to rotate in the opposite direction, so that the slide moves away from the drill rod. Then, the electric push rods on both sides of the lifting seat are operated to control the two clamping blocks to move away from each other, so that the cathode rod is removed from the outer surface of the lifting seat.

[0012] Preferably, the positioning device includes:

[0013] The grooved rod is fixed to one side of the frame plate to support the sliding rod;

[0014] A sliding rod slides on the inner wall of the groove rod. One end of the sliding rod is rotatably connected to a screw. A support rod is threaded onto the outer surface of the screw. Rotating the screw can control the support rod to slide up and down on one side of the sliding rod to adjust its height. A pad rod and a tapered rod are fixedly connected to the top two sides of the support rod, respectively. The distance between the center point of the tapered rod away from the support rod and the top surface of the pad rod is equal to the diameter of the drill rod.

[0015] The effect achieved by the above components is as follows: By setting the pad rod and the tapered rod, when the drilling device needs to adjust the drilling position of the cathode rod or drill cathode rods of different specifications, the cathode rod is first fixed to one side of the lifting seat by the clamping mechanism. Then, the sliding rod is pushed to slide away from the lifting seat on the inner wall of the groove rod so that the support rod is located below the drill rod. Then, the screw at one end of the sliding rod is rotated to control the support rod to move upward on the outer surface of the screw so that the top of the pad rod contacts the bottom surface of the drill rod. Then, the servo motor is operated to control the slide to move towards the drill rod so that one end of the cathode rod is located on one side of the tapered rod. The hydraulic rod on the outer surface of the frame plate is operated to control the lifting seat to rise or fall so that the center point of the drilling position of the cathode rod is aligned with the position of the tapered rod away from the support rod. At this time, the drilling position of the cathode rod is aligned with the position of the drill rod. Then, the screw is rotated to control the support rod to fall, and the servo motor is operated to control the slide to move so that one end of the cathode rod is attached to one end of the drill rod, and the cathode rod can be drilled.

[0016] Preferably, a magnetic block is fixedly connected to the end of the tapered rod away from the support rod.

[0017] The effect achieved by the above components is that when the sliding block moves one end of the cathode rod close to the tapered rod, the magnetic attraction between the magnetic block and the cathode rod can cause the magnetic block at one end of the tapered rod to be attracted to the surface of the cathode rod, making it more accurate to control the lifting seat to move up and down to align the cathode rod and the tapered rod.

[0018] Preferably, a support plate is fixedly connected to one end of the support rod near the tapered rod, and the support plate is located at the top of the tapered rod.

[0019] The effect achieved by the above components is as follows: after aligning the drilling position of the cathode rod with the center position of the drill rod through the positioning device, when drilling the cathode rod, the sliding rod can be pushed to move and adjust the position, and the screw can be rotated to adjust the height position of the support rod, so that the support plate is located below the cathode rod, supporting the bottom end of the cathode rod, and minimizing the possibility of the cathode rod's angle deflection during processing, which would affect the drilling effect.

[0020] Preferably, an operating block is fixedly connected to the bottom end of the screw, and the outer surface of the operating block is provided with two opposing protrusions.

[0021] The effect achieved by the above components is that the protrusions on both sides of the operating block make it easier to rotate the operating block to control the screw rotation and prevent the hand from slipping.

[0022] Preferably, one side of the sliding rod is provided with a fastening device that can further restrict the position of the sliding rod inside the groove rod. The fastening device includes a slider, which is fixed to one end of the sliding rod and slides on both sides of the inner wall of the groove rod. One end of the slider protrudes into the interior of the groove rod. A round rod is slidably connected to one side of the slider. A pressure block is fixedly connected to one end of the round rod. A spring is provided on one side of the pressure block. The spring is fixed between the pressure block and the slider to restrict the position of the pressure block. In its normal state, the spring pushes the pressure block to press one side of the pressure block against the outer surface of the groove rod.

[0023] The effect achieved by the above components is as follows: when controlling the movement of the sliding rod, the round rod is pulled to slide away from the groove rod on the inner wall of the slider, causing the pressure block to move away from the outer surface of the groove rod and compressing the spring. Then, the slider is pushed to control the sliding rod to move inside the groove rod. After adjusting the position of the sliding rod, the round rod is released and the spring restores its deformation, pushing the pressure block to move towards the groove rod, pressing one side of the pressure block against the outer surface of the groove rod, further fixing the position of the sliding rod inside the groove rod, and minimizing the possibility of the sliding rod sliding when the position of the support rod is moved, thus affecting the normal use of the positioning device.

[0024] Preferably, the outer surface of the end of the round rod away from the clamping block is rectangular.

[0025] The effect achieved by the above components is that by pinching the rectangular part of the round rod away from the clamping block, it is easier to pull the round rod to control the movement of the clamping block and it is less likely to slip.

[0026] Preferably, two protruding strips are fixedly connected to the side of the groove rod near the pressure block, and the protruding strips are rubber strips made of rubber material.

[0027] The effect achieved by the above components is that by setting the rubber protrusions, the friction between the pressure block and the groove rod when the pressure block presses on the outer surface of the groove rod can be increased, making the pressure block more stable and less prone to accidental slippage when fixing the position of the sliding rod on the groove rod surface.

[0028] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0029] In this invention, by setting a positioning device, when it is necessary to align the drilling position of the cathode rod with the position of the drill rod, the position of the sliding rod and the support rod is moved so that the top of the pad is attached to the bottom surface of the drill rod, and the lifting seat is moved to adjust the drilling position of the cathode rod to align with one end of the tapered rod. This allows the drilling position of the cathode rod to be quickly and conveniently aligned with the center position of the drill rod, thus minimizing the problem of the drilling position being skewed when changing the specifications of the cathode rod or changing the drilling position.

[0035] Example 1, such as Figure 1-2As shown, a drilling device for processing high-conductivity cathode steel rods includes a frame 1, a slide 5, and a clamping mechanism 6. The frame 1 is placed on the ground to support the entire device. A servo motor 4 and a lead screw driven by the servo motor 4 are installed on the outer surface of the frame 1. The rotation of the lead screw driven by the servo motor 4 controls the movement of the slide 5 on the outer surface of the frame 1. The clamping mechanism 6 is installed on the outer surface of the slide 5 and includes a frame plate 61, which is fixed to the top of the slide 5 to support the entire clamping mechanism 6. A hydraulic rod 62 is installed on one side of the frame plate 61 to control the movement of the lifting seat 63. The lifting seat 63 is fixed to one side of the output end of the hydraulic rod 62. By operating the hydraulic rod 62, the lifting seat 63 is controlled to slide up and down on one side of the frame plate 61. The outer surface of the lifting seat 63 is provided with a positioning device 2 to assist in positioning the angle between the cathode rod and the drill rod 8, which is fixed on one side of the lifting seat 63. An electric push rod 64 and a clamping block 65 are also provided. The two electric push rods 64 are respectively installed on both sides of the lifting seat 63, and the clamping block 65 is fixed to one side of the output rod of the electric push rod 64. By operating the electric push rod 64, the clamping block 65 can be controlled to move on one side of the lifting seat 63 to move the cathode rod. The device includes a rod clamp; it also includes a drive motor 7 and a drill rod 8. The drive motor 7 is mounted on the outer surface of the frame 1 at the end away from the servo motor 4. The drill rod 8 is mounted on the output end side of the drive motor 7. By operating the drive motor 7, the drill rod 8 is rotated. When using the drilling device, one end of the cathode rod is pressed against the outer surface of the lifting seat 63. The electric push rods 64 on both sides of the lifting seat 63 are extended to control the two clamping blocks 65 to move in the same direction, so that the clamping blocks 65 clamp and fix the cathode rod on one side of the lifting seat 63. Then, the servo motor 4 at one end of the frame 1 drives the lead screw inside the frame 1. The slide block 5 rotates, causing it to move threadedly on the outer surface of the lead screw and slide towards the drill rod 8 on the outer surface of the frame 1. One end of the cathode rod is pressed against one end of the drill rod 8. The drive motor 7 is operated to drive the drill rod 8 to rotate, and the slide block 5 slowly moves towards the drill rod 8. The cathode rod is drilled through the drill rod 8. After drilling is completed, the servo motor 4 is operated to control the lead screw to rotate in the opposite direction, causing the slide block 5 to move away from the drill rod 8. Then, the electric push rods 64 on both sides of the lifting seat 63 are operated to control the two clamping blocks 65 to move away from each other, and the cathode rod is removed from the outer surface of the lifting seat 63.

[0036] Reference Figure 1-4As shown in this embodiment: the positioning device 2 includes a grooved rod 21, which is fixed to one side of the frame plate 61 to support the sliding rod 22; the sliding rod 22 slides on the inner wall of the grooved rod 21, and a screw 23 is rotatably connected to one end of the sliding rod 22. A support rod 24 is threadedly connected to the outer surface of the screw 23. Rotating the screw 23 can control the support rod 24 to slide up and down on one side of the sliding rod 22 to adjust its height position. A pad rod 25 and a tapered rod 26 are fixedly connected to the top two sides of the support rod 24, respectively. The center point of the tapered rod 26 away from the support rod 24 is connected to the pad rod 25. The distance between the top surfaces of rod 25 is equal to the diameter of drill rod 8. By setting the pad rod 25 and the tapered rod 26, when it is necessary to adjust the drilling position of the cathode rod or to drill cathode rods of different specifications using the drilling device, the cathode rod is first fixed to one side of the lifting seat 63 by the clamping mechanism 6. Then, the sliding rod 22 is pushed to slide away from the lifting seat 63 on the inner wall of the groove rod 21 so that the support rod 24 is located below the drill rod 8. Then, the screw 23 at one end of the sliding rod 22 is rotated to control the support rod 24 to move upward on the outer surface of the screw 23 so that the pad rod 25... The top end contacts the bottom surface of the drill rod 8. Then, the servo motor 4 controls the slide 5 to move towards the drill rod 8, positioning one end of the cathode rod on one side of the tapered rod 26. The hydraulic rod 62 on the outer surface of the support plate 61 controls the lifting seat 63 to rise or fall, aligning the center point of the cathode rod's drilling position with the end of the tapered rod 26 furthest from the support rod 24. At this point, the cathode rod's drilling position is aligned with the drill rod 8. Then, the screw 23 is rotated to lower the support rod 24, and the servo motor 4 controls the slide 5 to move, causing one end of the cathode rod to fit against the drill rod 8. At one end, drilling can be performed on the cathode rod. By setting the positioning device 2, when it is necessary to align the drilling position of the cathode rod with the position of the drill rod 8, the position of the sliding rod 22 and the support rod 24 is moved so that the top of the pad is attached to the bottom surface of the drill rod 8, and the lifting seat 63 is moved to adjust the drilling position of the cathode rod to align with one end of the tapered rod 26. This allows the drilling position of the cathode rod to be quickly and conveniently aligned with the center position of the drill rod 8, minimizing the problem of the drilling position being skewed when changing the specifications of the cathode rod or changing the drilling position.

[0037] Reference Figure 2-4 As shown in this embodiment: a magnetic block 27 is fixedly connected to the end of the tapered rod 26 away from the support rod 24. When the sliding block 5 is moved so that one end of the cathode rod is close to the tapered rod 26, the magnetic block 27 at one end of the tapered rod 26 can be attracted to the surface of the cathode rod by the magnetic attraction between the magnetic block 27 and the cathode rod. This makes it more accurate to control the lifting seat 63 to move up and down to align the cathode rod and the tapered rod 26.

[0038] Reference Figure 2-4As shown in this embodiment: a support plate 28 is fixedly connected to one end of the support rod 24 near the tapered rod 26. The support plate 28 is located at the top of the tapered rod 26. After the positioning device 2 aligns the drilling position of the cathode rod with the center position of the drill rod 8, when drilling the cathode rod, the sliding rod 22 can be pushed to move and adjust the position, and the screw 23 can be rotated to adjust the height position of the support rod 24, so that the support plate 28 is located below the cathode rod, supporting the bottom end of the cathode rod, and avoiding the angle of the cathode rod from deviating during the processing as much as possible, which would affect the drilling effect. An operating block 29 is fixedly connected to the bottom end of the screw 23. Two opposing protrusions are provided on the outer surface of the operating block 29. Holding the protrusions on both sides of the operating block 29 makes it easier to rotate the operating block 29 to control the rotation of the screw 23 and prevents the hand from slipping.

[0039] Reference Figure 1 , Figure 3 and Figure 4 As shown in this embodiment: a fastening device 3 is provided on one side of the sliding rod 22 to further restrict the position of the sliding rod 22 inside the groove rod 21. The fastening device 3 includes a slider 31, which is fixed to one end of the sliding rod 22 and slides on both sides of the inner wall of the groove rod 21. One end of the slider 31 protrudes into the interior of the groove rod 21. A round rod 33 is slidably connected to one side of the slider 31. A pressure block 34 is fixedly connected to one end of the round rod 33. A spring 32 is provided on one side of the pressure block 34. The spring 32 is fixed between the pressure block 34 and the slider 31 to restrict the position of the pressure block 34. In its normal state, the spring 32 pushes the pressure block 34 to press one side of the pressure block 34 against the groove rod 21. When the sliding rod 22 moves, the round rod 33 is pulled to slide away from the groove rod 21 on the inner wall of the slider 31, causing the pressure block 34 to move away from the outer surface of the groove rod 21 and compress the spring 32. Then, the slider 31 is pushed to control the sliding rod 22 to move inside the groove rod 21. After adjusting the position of the sliding rod 22, the round rod 33 is released and the spring 32 restores its deformation, pushing the pressure block 34 to move towards the groove rod 21. One side of the pressure block 34 is pressed against the outer surface of the groove rod 21, further fixing the position of the sliding rod 22 inside the groove rod 21, and avoiding the sliding of the sliding rod 22 when the position of the support rod 24 is moved, which would affect the normal use of the positioning device 2.

[0040] Reference Figure 3 and Figure 4As shown in this embodiment: the outer surface of the end of the round rod 33 away from the clamping block 65 is rectangular. Pinching the round rod 33 at the rectangular end away from the clamping block 65 makes it easier to pull the round rod 33 to control the movement of the clamping block 65 and prevents slippage. Two protrusions 35 are fixedly connected to the side of the grooved rod 21 near the pressure block 34. The protrusions 35 are rubber strips made of rubber. By setting the rubber protrusions 35, the friction between the pressure block 34 and the grooved rod 21 when it presses against the outer surface of the grooved rod 21 can be increased, making the pressure block 34 more stable and less prone to accidental slippage when it presses against the surface of the grooved rod 21 to fix the position of the sliding rod 22.

[0041] Working principle: When using the drilling device, one end of the cathode rod is placed against the outer surface of the lifting seat 63. The electric push rods 64 on both sides of the lifting seat 63 extend, controlling the two clamping blocks 65 to move in the same direction, thus clamping and fixing the cathode rod to one side of the lifting seat 63. Then, the round rod 33 is pulled along the inner wall of the slider 31, sliding away from the groove rod 21, causing the pressure block 34 to move away from the outer surface of the groove rod 21 and compressing the spring 32. Subsequently, the slider 31 is pushed, controlling the sliding rod 22 to move inside the groove rod 21, thus supporting... Rod 24 is located below drill rod 8. After adjusting the position of sliding rod 22, the round rod 33 is released, and the spring 32 restores its deformation, pushing the pressure block 34 towards the groove rod 21. One side of the pressure block 34 is pressed against the outer surface of the groove rod 21, further fixing the position of sliding rod 22 inside the groove rod 21. Then, the screw 23 at one end of sliding rod 22 is rotated to control the support rod 24 to move upward on the outer surface of screw 23, so that the top of pad rod 25 contacts the bottom surface of drill rod 8. Then, the servo motor 4 is operated to control the slide 5. Move the cathode rod towards drill rod 8 so that one end of the cathode rod is positioned on one side of the tapered rod 26. The hydraulic rod 62 on the outer surface of the operating frame plate 61 controls the lifting seat 63 to rise or fall, aligning the center point of the cathode rod's drilling position with the end of the tapered rod 26 furthest from the support rod 24. At this point, the cathode rod's drilling position is aligned with the drill rod 8. Then, rotate the screw 23 to control the support rod 24 to fall. Subsequently, the servo motor 4 at one end of the operating frame 1 drives the lead screw to rotate inside the frame 1, causing the slide 5 to move threadedly on the outer surface of the lead screw. The cathode rod slides on the outer surface of the frame 1 towards the drill rod 8, with one end of the cathode rod against one end of the drill rod 8. The drive motor 7 is operated to drive the drill rod 8 to rotate, and the slide block 5 is slowly moved towards the drill rod 8. The cathode rod is drilled through the drill rod 8. After drilling is completed, the servo motor 4 is operated to control the lead screw to rotate in the opposite direction, so that the slide block 5 moves away from the drill rod 8. Then, the electric push rods 64 on both sides of the lifting seat 63 are operated to control the two clamping blocks 65 to move away from each other, so that the cathode rod is removed from the outer surface of the lifting seat 63.
