Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a multi-specification hole diameter adaptive positioning drilling device for street light poles. Background Technology

[0002] As an important infrastructure of urban lighting systems, street light poles require drilling of various hole sizes at different heights and locations during their production process to facilitate the subsequent installation of crossarms, access gates, or wiring.

[0003] Current street light pole drilling equipment still faces the following major technical problems in practical applications: First, traditional drilling equipment typically uses standard cylindrical drill bits, meaning a single drill bit diameter can only process holes of that specific size, requiring frequent bit changes and reducing drilling efficiency. Second, the metal drilling process generates a large amount of high-temperature, sharp metal debris. This residual debris is repeatedly crushed by the rotating drill bit, resulting in "secondary cutting," severely scratching the hole wall, reducing surface finish, and accelerating drill bit wear, thus shortening tool life. Therefore, a multi-specification adaptive positioning drilling device for street light poles is proposed. Summary of the Invention

[0004] This invention provides a multi-diameter adaptive positioning drilling device for street light poles. It achieves precise longitudinal positioning of the drilling frame through a shifting motor and a reciprocating lead screw. A positioning cylinder and an arc-shaped clamping plate provide adaptive rigid clamping for street light poles of different diameters, ensuring processing stability. A tapered drill rod with a tapered bottom and a thicker top, combined with real-time feedback from a distance sensor, allows for precise control of the drilling depth, enabling the processing of multiple diameter holes with a single drill bit. This solves the problems mentioned in the background art, such as frequent tool changes leading to low efficiency, and the risk of "secondary cutting" due to untimely chip removal, which severely scratches the hole wall, reduces surface finish, accelerates drill bit wear, and shortens tool life.

The rotating shaft of the drilling motor passes through the center of the driving box, and the bottom ends of the two sets of linkage shafts pass through the driving box. The rotating shaft of the drilling motor is connected to the two sets of linkage shafts through a sprocket set.

[0010] As a preferred embodiment of the present invention, the drive box is filled with coolant, and multiple sets of atomizing nozzles are equally spaced at the bottom of the drive box. The input end of the atomizing nozzle is connected to the inner cavity of the drive box, and the output end of the atomizing nozzle is inclined toward the outer wall of the drill rod. The mounting plate is provided with a pressurizing part that pushes the coolant in the drive box to be sprayed out along the atomizing nozzle.

[0011] As a preferred embodiment of the present invention, the pressurizing part includes a pressurizing chamber, which is fixedly connected to the mounting plate.

[0013] As a preferred embodiment of the present invention, the top of the piston chamber is fixed and connected to an air supply pipe, and a one-way valve is provided inside the air supply pipe.

[0014] As a preferred embodiment of the present invention, mounting seats are fixedly connected to both sides of the top of the support platform, and a reciprocating screw is rotatably connected between the two sets of mounting seats.

[0015] Compared with the prior art, the present invention provides a multi-specification aperture adaptive positioning drilling device for street light poles, which has the following beneficial effects: 1. This multi-diameter adaptive positioning drilling equipment for streetlight poles uses a shifting motor and a reciprocating lead screw to achieve precise longitudinal positioning of the drilling frame. A positioning cylinder and an arc-shaped clamping plate provide adaptive rigid clamping for streetlight poles of different diameters, ensuring processing stability. It employs a tapered drill rod that is thinner at the bottom and thicker at the top, with real-time feedback from a distance sensor. By precisely controlling the depth of penetration, a single drill bit can process multiple diameter holes without frequent tool changes, significantly improving the equipment's adaptability and drilling efficiency. Simultaneously, it avoids impacts during idle strokes, protecting the drill rod and the workpiece.

[0016] 2. This street light pole multi-specification hole diameter adaptive positioning drilling equipment uses the power of the drilling motor spindle to directly drive the guide vanes to rotate and generate negative pressure, which sucks away the debris generated in the drilling area. Through the near-source design of the suction groove at the top of the arc-shaped clamping plate, high-temperature debris can be extracted in time, effectively preventing secondary cutting and hole wall scratches caused by debris retention, greatly improving processing accuracy and surface finish; at the same time, it reduces drill bit wear and extends service life.

[0017] 3. This street light pole multi-specification diameter adaptive positioning drilling equipment uses the kinetic energy of the airflow discharged from the chip extraction to drive the pneumatic impeller. It uses the principle of magnetic repulsion to convert the rotational motion into the reciprocating motion of the piston, thereby continuously pressurizing the drive box. The coolant is sprayed onto the side wall of the drill rod after being atomized under high pressure, which quickly removes heat and softens the chips. This not only solves the problem of heat dissipation of the drill rod and improves the quality of the hole wall, but also realizes the immediate stopping and interruption of the coolant, eliminating resource waste and environmental pollution.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Reference Figures 1-9 A multi-specification aperture adaptive positioning drilling device for street light poles includes a support platform 1, on which a support frame is fixedly connected. It also includes a drilling frame 2 that translates along the long axis of the support platform 1. A positioning cylinder 21 is fixedly connected to the top of the drilling frame 2, and a clamping frame 22 is fixedly connected to the telescopic end of the positioning cylinder 21. The clamping frame 22 is provided with a clamping part for welding positioning. Mounting seats 8 are fixedly connected to both sides of the top of the support platform 1, and a reciprocating screw 81 is rotatably connected between the two sets of mounting seats 8. A displacement motor 8 is fixedly connected to one of the mounting seats 8. 2. The output end of the shift motor 82 is fixedly connected to the end of the reciprocating lead screw 81. The drilling frame 2 is threaded onto the reciprocating lead screw 81. Both sides of the bottom of the drilling frame 2 are rotatably connected to pulleys 83, which are in contact with the top of the support platform 1. The bottom of the mounting plate 3 and the clamping frame 22 is fixedly connected to the drilling cylinder 31. The mounting plate 3 is fixedly connected to the bottom of the telescopic end of the drilling cylinder 31. The mounting plate 3 is provided with a drilling part for drilling holes in the street light pole and a chip collection part, which is provided on the mounting plate 3 to collect the chips generated during drilling.

[0023] Reference Figures 1-4The clamping part includes two sets of movable plates 4. The bottom sides of the clamping frame 22 are provided with limit grooves 41. The tops of the two sets of movable plates 4 are slidably connected in the limit grooves 41 on both sides. The clamping frame 22 is fixedly connected to both sides of the clamping cylinder 42. The telescopic end of the clamping cylinder 42 is fixedly connected to the side wall of the movable plate 4. The bottom ends of the two sets of movable plates 4 are fixedly connected to the arc-shaped clamping plate 43. The drilling part includes a drilling motor 5. The drilling motor 5 is fixedly connected to the bottom of the mounting plate 3. The bottom end of the rotating shaft of the drilling motor 5 is fixedly connected to a drill rod 51. The drill rod 51 has a tapered design that is thinner at the bottom and thicker at the top. The bottom of the mounting plate 3 is fixedly connected to a distance sensor 52. The detection direction of the distance sensor 52 is parallel to the drilling direction of the drill rod 51. The distance sensor 52, the drilling cylinder 31 and the drilling motor 5 are electrically connected.

[0024] With the above structure, when the street light pole to be processed is placed on the support frame of the support platform 1, the control shift motor 82 is started. The output end of the shift motor 82 drives the reciprocating screw 81 to rotate. Since the drilling frame 2 is threaded onto the reciprocating screw 81 and its bottom is in rolling cooperation with the support platform 1 through the pulley 83, the drilling frame 2 will smoothly move along the long axis of the support platform 1 until it moves directly above the street light pole to be drilled. After reaching the designated position, the positioning cylinder 21 starts to move, pushing the clamping frame 22 downward until the arc-shaped clamping plate 43 moves to both sides of the street light pole. Then, the clamping cylinders 42 on both sides extend synchronously, driving the two sets of moving plates 4 to move towards each other along the limiting slide groove 41, causing the arc-shaped clamping plate 43 at the bottom to tightly hug the outer wall of the street light pole. The arc design of the arc-shaped clamping plate 43 ensures adaptive fitting for street light poles of different diameters, completing the rigid fixation of the workpiece and the precise positioning before drilling, ensuring The stability of subsequent drilling is ensured. After clamping, the drilling cylinder 31 drives the mounting plate 3 and the drilling section below it to move downwards, bringing the distance sensor 52 close to the surface of the street light pole. The distance sensor 52 detects the distance between the drill bit and the pole in real time and feeds the signal back to the control system to accurately control the starting point of the drill bit and avoid idle impact. Subsequently, the drilling motor 5 starts, driving the tapered drill rod 51 to rotate at high speed. The drilling cylinder 31 continues to push the drill rod 51 downwards to start the drilling operation. Using the tapered drill rod 51, which is thinner at the bottom and thicker at the top, and the real-time data measured by the distance sensor 52, the pressing depth of the drilling cylinder 31 is accurately calculated and controlled. Since the diameter of the drill rod 51 changes linearly with the axial position, when the drill rod 51 is pressed down to a specific depth, the diameter at that section is the target hole diameter. In this way, multiple hole diameters can be processed without changing the drill rod 51, which greatly improves the adaptability of the equipment and the drilling efficiency.

[0025] Reference Figures 2-6The dust collection unit includes two sets of guide boxes 6, which are fixed on both sides of the mounting plate 3. A linkage shaft 61 is rotatably connected inside the guide box 6. A guide blade 62 is fixedly connected to the outer wall of the linkage shaft 61. An adsorption groove 431 is opened in the arc-shaped clamping plate 43. The bottom of the guide box 6 is fixed and connected to an exhaust pipe 63. The other end of the exhaust pipe 63 is connected to the inner cavity of the adsorption groove 431. A filter plate 432 is fixedly connected at the connection point on the inner wall of the adsorption groove 431. An adsorption port 433 is opened at the top of the adsorption groove 431. The mounting plate 3 is provided with a drive unit for driving the two sets of linkage shafts 61 to rotate. The drive unit includes a drive box 64, which is fixedly connected to the mounting plate 3. The rotating shaft of the drilling motor 5 passes through the center of the drive box 64. The bottom ends of the two sets of linkage shafts 61 are both inserted into the drive box 64. The rotating shaft of the drilling motor 5 is connected to the two sets of linkage shafts 61 through a sprocket set 65.

[0026] With the above-described structure, when the drilling motor 5 rotates, its shaft transmits power to two sets of linkage shafts 61 through the sprocket assembly 65 in the drive box 64, driving the guide vanes 62 in the guide box 6 to rotate at high speed. This creates a negative pressure suction environment at the bottom of the guide box 6, which is then transmitted to the adsorption tank 431 through the exhaust pipe 63. At the same time, the high-temperature debris generated during drilling flies to both sides under the action of centrifugal force and airflow. At this time, the negative pressure suction generated at the adsorption port 433 sucks in the debris from the drilling area. This firstly prevents the debris from remaining in the drilling area and causing secondary cutting, thereby improving the processing accuracy and hole wall quality. Secondly, it reduces the secondary wear of the drill rod 51 caused by the debris, increasing the service life of the drill rod 51. In addition, it prevents the debris from scattering in the drilling area, improving the cleanliness of the drilling area. Moreover, this process does not require an additional motor, directly reusing the main drilling power, which is energy-saving and highly synchronous.

[0027] Reference Figure 7 In addition, a chip discharge port is provided at the bottom of the adsorption tank 431, and a baffle for sealing the chip discharge port is detachably connected to the arc-shaped clamp 43 so as to clean the debris collected in the adsorption tank 431 regularly.

[0028] Reference Figures 2-6 and Figure 9The drive box 64 is filled with coolant. Multiple sets of atomizing nozzles 641 are evenly spaced at the bottom of the drive box 64. These atomizing nozzles 641 utilize existing mature technology and include a swirling chamber, a one-way valve, and extremely small nozzles. Under pressure, they atomize and spray the coolant. The input end of the atomizing nozzle 641 is connected to the inner cavity of the drive box 64, and the output end of the atomizing nozzle 641 is inclined towards the outer wall of the drill rod 51. The mounting plate 3 is equipped with a pressurizing section that pushes the coolant in the drive box 64 out along the atomizing nozzles 641. The pressurizing section includes a pressurizing chamber 7, which is fixedly connected to the mounting plate 3. A piston chamber 71 is fixedly connected to the side wall of the pressurizing chamber 7. A pressurizing pipe 711 is fixedly connected to the drive box 64, and a pressure pipe 711 is installed inside the pressurizing pipe 711. A one-way valve is provided. A pneumatic impeller 72 is rotatably connected inside the pressurization chamber 7. The top of the pressurization chamber 7 is fixed and connected to an exhaust pipe 73. The exhaust pipe 73 is Y-shaped, and its two input ends are connected to the top of the inner cavity of the guide box 6. Multiple sets of first magnetic plates 721 are fixed at equal intervals at the end of the pneumatic impeller 72. A second magnetic plate 74 is slidably connected inside the piston chamber 71. A return spring 741 is fixedly connected between the second magnetic plate 74 and the inner wall of the piston chamber 71. The first magnetic plate 721 and the second magnetic plate 74 are magnetically repelled. An exhaust port 75 is provided at the bottom of the pressurization chamber 7. The output end of the exhaust pipe 73 is offset from the center of the pressurization chamber 7 and faces the pneumatic impeller 72. The top of the piston chamber 71 is fixed and connected to an air supply pipe 712, and a one-way valve is provided inside the air supply pipe 712.

[0029] It should be noted that the one-way valve in the pressurization pipe 711 can only allow the gas in the piston chamber 71 to enter the drive box 64; while the one-way valve in the air supply pipe 712 can only allow external airflow to supplement the piston chamber 71.

[0030] With the above structure, debris is filtered by the debris filter plate 432 and enters the guide box 6. After passing through the guide vane 62, it enters the pressurization chamber 7 along the exhaust pipe 73 and impacts the wind turbine impeller 72 at a high speed with a tangential angle, driving the wind turbine impeller 72 to rotate at high speed (the exhaust gas is discharged from the bottom exhaust port 75 after doing work). At this time, the first magnetic plate 721 at the end of the wind turbine impeller 72 rotates with it, and the magnetic repulsion between the first magnetic plate 721 and the second magnetic plate 74 is used to push the second magnetic plate 74 to reciprocate in the piston chamber 71. When the second magnetic plate 74 slides to the side of the compression return spring 741, it will compress the gas in the piston chamber 71 and open the one-way valve in the pressurization pipe 711, so that the compressed airflow enters the drive. Inside the drive box 64, when the first magnetic plate 721 and the second magnetic plate 74 are separated from the repulsive area, the second magnetic plate 74 will slide in the opposite direction under the rebound action of the return spring 741. At this time, a negative pressure suction force will be generated in the piston chamber 71, thereby opening the one-way valve in the air supply pipe 712, allowing external airflow to be supplied to the piston chamber 71. This process repeats, continuously filling the drive box 64 with gas during the drilling process. When the pressure exceeds the opening threshold of the one-way valve inside the nozzle, the coolant opens the valve and is sprayed at an angle in an atomized form onto the outer wall of the drill rod 51 through its output end. At this time, the atomized water mist can quickly remove the cutting heat, soften the chips, and use the airflow to blow the residual micro-chips away from the cutting area, significantly extending the life of the drill rod 51 and improving the surface finish of the hole.

[0031] In addition, the coolant in the drive box 64 can also cool the shaft of the drilling motor 5 and the sprocket assembly 65. First, it prevents the drilling heat from being transferred to the drilling motor 5 along the shaft of the drilling motor 5, thus improving the protection of the drilling motor 5. Second, it cools down the sprocket assembly 65. Furthermore, the agitation of the sprocket assembly 65 can also achieve efficient heat exchange of the coolant, effectively improving the service life of the equipment.

[0032] Reference Figures 1-9 In this invention, when the street light pole to be processed is placed on the support frame of the support platform 1, the shift motor 82 is started. The output end of the shift motor 82 drives the reciprocating screw 81 to rotate. Since the drilling frame 2 is threaded on the reciprocating screw 81 and the bottom is in rolling cooperation with the support platform 1 through the pulley 83, the drilling frame 2 will move smoothly along the long axis of the support platform 1 until it moves directly above the street light pole to be drilled. After reaching the designated position, the positioning cylinder 21 starts to move, pushing the clamping frame 22 down until the arc-shaped clamping plate 43 moves to both sides of the street light pole. Then, the clamping cylinders 42 on both sides extend synchronously, driving the two sets of moving plates 4 to move towards each other along the limiting slide groove 41, causing the arc-shaped clamping plate 43 at the bottom to tightly hug the outer wall of the street light pole. The arc design of the arc-shaped clamping plate 43 ensures adaptive fitting for street light poles of different diameters, completing the rigid fixation of the workpiece and precise positioning before drilling.

[0033] After clamping, the drilling cylinder 31 drives the mounting plate 3 and the drilling section below it to move downwards, bringing the distance sensor 52 close to the surface of the street light pole. The distance sensor 52 detects the distance between the drill bit and the pole in real time and feeds the signal back to the control system to accurately control the starting point of the drill bit and avoid backlash. Subsequently, the drilling motor 5 starts, driving the tapered drill rod 51 to rotate at high speed. The drilling cylinder 31 continues to push the drill rod 51 downwards to start the drilling operation. Using the tapered drill rod 51, which is thinner at the bottom and thicker at the top, and the real-time data measured by the distance sensor 52, the pressing depth of the drilling cylinder 31 is accurately calculated and controlled. Since the diameter of the drill rod 51 changes linearly with the axial position, when the drill rod 51 is pressed down to a specific depth, the diameter at that section is the target hole diameter. In this way, various hole diameters can be processed without changing the drill rod 51.

[0034] When the drilling motor 5 rotates, its shaft transmits power to two sets of linkage shafts 61 through the sprocket set 65 in the drive box 64, driving the guide vanes 62 in the guide box 6 to rotate at high speed, thereby creating a negative pressure suction environment at the bottom of the guide box 6, and transmitting it to the adsorption tank 431 through the exhaust pipe 63. At the same time, the high-temperature debris generated by drilling flies to both sides under the action of centrifugal force and airflow. At this time, the negative pressure suction generated at the adsorption port 433 sucks in the debris in the drilling area, realizing the effective collection of debris and preventing debris from being stuck in the drilling area.

[0035] Subsequently, the debris is filtered by the debris filter plate 432 and enters the guide box 6. After passing through the guide vanes 62, it enters the pressurization chamber 7 along the exhaust pipe 73 and impacts the wind turbine impeller 72 at high speed at a tangential angle, driving the wind turbine impeller 72 to rotate at high speed. At this time, the first magnetic plate 721 at the end of the wind turbine impeller 72 rotates with it. Utilizing the magnetic repulsion between the first magnetic plate 721 and the second magnetic plate 74, the second magnetic plate 74 is pushed to reciprocate within the piston chamber 71. When the second magnetic plate 74 slides towards the side of the compression return spring 741, it compresses the gas in the piston chamber 71 and opens the one-way valve in the pressurization pipe 711, allowing the compressed airflow to enter the drive box 64. When the first magnetic plate 721... After the second magnetic plate 74 is separated from the repulsive region, the second magnetic plate 74 will slide in the opposite direction under the rebound action of the return spring 741. At this time, a negative pressure suction force will be generated in the piston chamber 71, thereby opening the one-way valve in the air supply pipe 712, allowing external airflow to be supplied into the piston chamber 71. This process will continue, continuously filling the drive box 64 with gas during the drilling process. When the pressure exceeds the opening threshold of the one-way valve inside the nozzle, the coolant will open the valve and be sprayed at an angle in an atomized form onto the outer wall of the drill rod 51 through its output end. At this time, the atomized water mist can quickly remove the cutting heat, soften the chips, and use the airflow to blow the residual micro-chips away from the cutting area, significantly extending the life of the drill rod 51 and improving the surface finish of the hole.
