Description

Technical Field

[0001] This invention relates to the field of terminal block processing technology, specifically to an integrated drilling and tapping device for terminal blocks. Background Technology

[0002] Terminal blocks, meaning insulating components that carry multiple or more sets of mutually insulated terminal assemblies and are used for fixing and supporting parts, play an important role in electrical power distribution systems, industrial control cabinets, and data center computer rooms. Key connection components such as neutral terminal blocks, grounding copper busbars, double-row grounding busbars, distribution box terminal blocks, and computer room terminal blocks undertake important functions of current distribution, safety grounding, and signal transmission.

[0003] However, existing neutral terminal blocks still have the following problems when drilling and tapping: 1. When drilling and tapping terminal blocks, a single drill bit is generally used, which is slow. When multi-axis machining is used simultaneously, the short distance between two adjacent holes in the neutral terminal block causes the spring collets to obstruct each other. 2. Existing integrated drilling and tapping equipment relies on workers to manually place and adjust the position of the neutral terminal block, which makes it prone to errors during processing and is also slow. 3. Existing integrated drilling and tapping equipment does not easily collect waste chips during tapping, and the waste chips left in the hole can easily damage the thread teeth. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated drilling and tapping device for terminal blocks. The main purpose is to solve the problems of short hole spacing in existing neutral terminal blocks, difficulty in multi-hole processing and manual placement and adjustment of the neutral terminal block position in existing integrated drilling and tapping devices, which easily leads to errors and debris residue in the holes, causing damage to the threads.

[0032] Please see Figures 1-16 As shown, an integrated drilling and tapping device for terminal blocks includes a workbench 1. Three support frames 11 are bolted to the top surface of the workbench 1. One support frame 11 houses a scoring component 9 for scoring the areas on the surface of the neutral terminal block where drilling is required. A drilling component 2 is installed inside the support frame 11 located to one side of the scoring component 9, simultaneously machining multiple holes on the surface of the neutral terminal block. A tapping component is installed inside the support frame 11 opposite the scoring component 9, simultaneously tapping multiple holes on the surface of the neutral terminal block. 3. Below the knocking component 9, there is a conveying component 5 for conveying the neutral terminal block; below the drilling component 2, there is a draining component 7 for discharging coolant; below the tapping component 3, there is a positioning component 6 for positioning the neutral terminal block; inside the support frame 11, there is a slag suction component 8 for collecting waste chips; on the top surface of the support frame 11, there is a transfer component 4 for transferring the neutral terminal block to a different work position; the top surface of the workbench 1 is bolted to the feeding mechanism 10; and on one side of the feeding mechanism 10, there is a discharge mechanism 101.

[0033] It should be noted that the feeding mechanism 10 and the discharging mechanism 101 in this application both include belts, motors, rollers, idlers and frames, which are existing technologies. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0034] To solve the technical problem of drilling holes in the neutral terminal block, the drilling assembly 2 of this invention includes a switching mechanism disposed at the top of one of the support frames 11. The switching mechanism includes a first connecting plate 21 fixedly connected to the top of the support frame 11. A second motor 29 is mounted on the top surface of each first connecting plate 21. The output shaft of the second motor 29 is fixedly connected to a third gear 210 via a coupling. A fourth gear 211 is meshed with the surface of the third gear 210. The fourth gear 211 is rotatably connected to the first connecting plate 21 via a bearing. Four positioning grooves 212 are evenly formed on the surface of the first connecting plate 21. Each positioning groove 212 is slidably connected inside. There is a linkage block 213, which is fixedly connected to the fourth gear 211. Each linkage block 213 has a guide rod 216 slidably connected inside. The surfaces of two linkage blocks 213 are fixedly connected to positioning blocks 214. Two electromagnetic locks 215 are installed on the top surface of the first connecting plate 21. The extension end of the electromagnetic lock 215 is inserted into the interior of the positioning block 214. The bottom end of the guide rod 216 is provided with a lifting mechanism. The lifting mechanism includes a first electric push rod 22 fixedly connected to the top surface of the first connecting plate 21. The output shaft of the first electric push rod 22 passes through the surface of the first connecting plate 21 and is rotatably connected to a connecting frame 23. The connecting frame 23 is connected to four guide rods 216. Rod 216 is fixedly connected. Inside the connecting frame 23, two second gears 26 are symmetrically rotated via bearings. Each second gear 26 has a first gear 25 meshing with its surface. A first motor 24 is installed inside the connecting frame 23. The output shaft of the first motor 24 is fixedly connected to the first gear 25. A linkage shaft is fixedly connected inside the second gears 26, passing through the bottom surface of the connecting frame 23 and fixedly connected to spring collets 27. Each spring collet 27 holds a drilling bit 28. Two universal bamboo-joint tubes 217 are installed on the bottom surface of the connecting frame 23. The universal bamboo-joint tubes 217 are interconnected with an external cooling tank via flexible hoses. When at zero... When drilling holes in the terminal block, the first motor 24 is connected to an external power source and started. The first gear 25 drives the second gear 26 to rotate, which in turn drives the drilling bit 28 to rotate through the spring collet 27. At the same time, the first electric push rod 22 is connected to an external power source and started. The first electric push rod 22 drives the connecting frame 23 to move towards the neutral terminal block. The coolant is delivered into the interior of the universal bamboo tube 217 through a hose by an external water pump and finally sprayed onto the surface of the neutral terminal. Because the two drilling bits 28 are staggered and inclined, two holes can be drilled on the surface of the neutral terminal at the same time, thus realizing multi-hole processing of the neutral terminal and speeding up the work efficiency.

[0035] After all six holes have been machined, the second motor 29 is connected to an external power source and started. The third gear 210 drives the fourth gear 211 to rotate, causing the linkage block 213 to drive the guide rod 216 to slide inside the positioning groove 212. This causes the connecting frame 23 to indirectly drive the two drilling bits 28 to rotate around the center of the connecting frame 23 until they are limited by the positioning groove 212. The second motor 29 is then turned off. Then, the electromagnetic lock 215 is connected to an external power source and started. The extension shaft of one of the electromagnetic locks 215 is inserted into the positioning block 214, thus limiting the position of the drilling bit 28 and allowing it to rotate. The remaining holes can then be machined.

[0036] To solve the technical problem of tapping the neutral terminal block, the tapping assembly 3 used in this invention includes two third motors 33 disposed inside another connecting frame 23. The output shaft of the third motor 33 is fixedly connected to a torque limiter 32. The end of the torque limiter 32 away from the third motor 33 is fixedly connected to a first gear 25. A tap 31 is held inside the spring collet 27. When it is necessary to tap the neutral terminal, the third motor 33 is connected to an external power source and started. The torque limiter 32 will indirectly drive the tap 31 to rotate. Then, the tap 31 is raised and lowered in the same way as drilling to perform tapping. Then, the hole position is switched in the same way as drilling, thereby realizing the tapping of the neutral terminal.

[0037] When the torque of tap 31 is too high due to a sudden cause during tapping, in order to prevent the third motor 33 from being damaged due to overload, the torque limiter 32 will be triggered, the transmission chain will actively disconnect at the set overload point, thereby disconnecting the third motor 33 from tap 31, then stopping the output shaft of the third motor 33, causing the torque limiter 32 to re-engage, then unwinding the tap by flipping, and then tapping again.

[0038] To address the technical problem of positioning and indenting before drilling the neutral terminal block, the present invention employs a marking assembly 9, which includes a fifth electric push rod 92 mounted on the top surface of one of the support frames 11. The output shaft of the fifth electric push rod 92 passes through the surface of the support frame 11 and is fixedly connected to a connecting column 93 via a coupling. The bottom end of the connecting column 93 is symmetrically connected to two extrusion tops 91 by bolts. To prevent the drilling bit 28 from deflecting during drilling, the neutral terminal block is placed below the extrusion tops 91 before drilling. The fifth electric push rod 92 is then connected to an external power source and started. The connecting column 93 drives the extrusion tops 91 to move towards the neutral terminal block until the extrusion tops 91 extrude grooves into the surface of the neutral terminal block. This ensures that when the drilling bit 28 drills, it is limited by the grooves, thus preventing deflection during drilling.

[0039] To solve the technical problem of processing and transferring neutral terminal blocks, this invention employs a workbench 1 with a turntable 41 mounted on its top surface. Four support columns 42 are evenly mounted on the top surface of the turntable 41. A fixed platform 43 is fixedly connected to the top of each support column 42. A fourth motor 44 is mounted on the surface of the fixed platform 43. The output shaft of the fourth motor 44 passes through the surface of the fixed platform 43 and is fixedly connected to a first lead screw 45 via a coupling. The first lead screw 45 is threadedly connected to a second connecting plate 46 via a screw thread. A second electric push rod 47 is mounted on the surface of the second connecting plate 46. The output shaft of the second electric push rod 47 passes through the second connecting plate 46. A finger cylinder 48 is mounted on the surface of the connecting plate 46. The output shaft of the finger cylinder 48 is fixedly connected to a clamping plate 49. A locking mechanism 410 is mounted on the top surface of the workbench 1 via a bracket. To facilitate the switching between processes of the neutral wire terminal block, the terminal block is first conveyed on the surface of the feeding mechanism 10 until it can no longer move. Then, the fourth motor 44 is connected to an external power source and started. The rotation of the first lead screw 45 will drive the second connecting plate 46 to move through the screw barrel until the finger cylinder 48 is located above the neutral wire terminal block. Then, the second electric push rod 47 is connected to an external power source and started. 48 will move towards the neutral terminal block until the two clamping plates 49 are located on both sides of the neutral terminal block. Then, the finger cylinder 48 is connected to an external power source and started. The two clamping plates 49 will move towards the neutral terminal block. Since the surfaces of the clamping plates 49 near the neutral terminal block are fixedly connected with positioning protrusions, the positioning protrusions will insert into the interior of the neutral terminal block. While clamping the neutral terminal block, the neutral terminal block is also positioned, thereby achieving precise position transfer. Then, the second connecting plate 46 will drive the neutral terminal block to a position coaxial with the extrusion top 91, and the extrusion top 91 will achieve... The neutral terminal block is marked with a hammer, and then the motor inside the turntable 41 is started to make the support column 42 rotate around the axis of the turntable 41. After rotating 90 degrees, the cylinder inside the locking mechanism 410 will extend towards the turntable 41 until the turntable 41 is limited, so that the turntable 41 rotates 90 degrees accurately each time. Then, the neutral terminal block is drilled and tapped by the drilling bit 28 and the tap 31. After rotating again, the finished neutral terminal block is aligned with the feeding mechanism 101. Then, the neutral terminal block is placed on the surface of the feeding mechanism 101 by the finger cylinder 48 for feeding.

[0040] It should be noted that: In this application, the turntable 41 includes the motor, turntable, bearing, protective shell and base, which are existing technologies. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0041] To solve the technical problem of conveying the neutral terminal block to a suitable position, the present invention employs a conveying assembly 5, which includes a first positioning plate 53 fixedly connected to the top surface of the workbench 1 via a bracket. Two first guide rails 54 are symmetrically fixedly connected to the top surface of the first positioning plate 53. A placement platform 51 is slidably connected to the surface of the first guide rails 54 via a first guide block 57. A receiving groove 52 is provided inside the placement platform 51. A fifth motor 55 is mounted on one side of the first positioning plate 53 via a mounting plate. The output shaft of the fifth motor 55 is fixedly connected to a second lead screw 56 via a coupling. The first guide block 57 is threadedly connected to the second lead screw 56 via a threaded cylinder. Two positioning rods 59 are symmetrically fixedly connected to the bottom surface of the placement platform 51, each positioning rod 59 penetrating the first guide block 54. 7. A positioning rod 59 is slidably connected to a positioning plate 53. Two first springs 58 are symmetrically wound around the surface of the positioning rod 59. The two ends of each first spring 58 are fixedly connected to the first positioning plate 53 and the first guide block 57, respectively. A leakage component 7 is located below the first positioning plate 53, which is below the drilling assembly 2 and the tapping assembly 3. The leakage component 7 includes two inclined blocks 73 fixedly connected to the top surface of the first positioning plate 53. A leakage groove 72 is formed on the surface of the first positioning plate 53. A collection tank 71 is located below the first positioning plate 53, below the leakage groove 72. The positioning assembly 6 includes several second positioning plates 61 fixedly connected to the top surface of the workbench 1 via a bracket. Two second positioning plates 61 are located on either side of the first positioning plate 53. Each first... Each of the two positioning plates 61 has a third electric push rod 62 mounted on its top surface. The output shaft of each third electric push rod 62 is fixedly connected to a support frame 66. Two second guide rails 63 are symmetrically fixedly connected to the top surface of the second positioning plate 61. A third connecting plate 65 is slidably connected to the surface of each second guide rail 63 via a second guide block 64. The third connecting plate 65 is fixedly connected to the support frame 66. A first limiting block 67 is slidably connected inside each support frame 66. Two positioning posts 68 are fixedly connected to adjacent sides of the two first limiting blocks 67. A limiting frame 69 is provided at one end of each first limiting block 67, and the limiting frame 69 is slidably connected to the two first limiting blocks 67. A fourth electric push rod 611 is installed inside the support frame 11. The output shaft of the fourth electric push rod 611... The output shaft is fixedly connected to the limiting frame 69. Two third guide rails 610 are symmetrically fixedly connected inside the support frame 11. The third guide rails 610 are fixedly connected to the limiting frame 69 via sliders. A slag suction assembly 8 is installed inside the support frame 66 located below the drilling assembly 2 and the tapping assembly 3. When the finger cylinder 48 transmits the neutral wire terminal block to a position coaxial with the support frame 11, the finger cylinder 48 releases the limiting position on the neutral wire terminal block. The neutral wire terminal block falls into the receiving groove 52 due to gravity, achieving initial positioning of the neutral wire terminal block. Then, the fifth motor 55 is connected to an external power source and started. The first guide block 57 slides on the surface of the first guide rail 54 due to the threaded cylinder until it slides below the extrusion top 91.Then, the third electric push rod 62 is connected to an external power source and started. The third connecting plate 65 slides on the surface of the second guide rail 63 via the second guide block 64, causing the two support frames 66 to move closer to the neutral terminal block. The two first limiting blocks 67 also move closer to each other inside the limiting frame 69 due to the movement of the support frames 66, until the positioning post 68 is inserted into the hole of the neutral terminal block. This achieves precise positioning of the neutral terminal block, preventing it from moving during hammering, drilling, and tapping. After each processing cycle, the first... The four electric push rods 611 are connected to an external power source and activated. The limiting frame 69 slides on the inner surface of the third guide rail 610, causing the two first limiting blocks 67 to move the neutral terminal block. Due to the limiting effect of the receiving groove 52 on the neutral terminal block, the placement table 51 slides inside the first guide block 57 via the positioning rod 59, thereby adjusting the hole position of the neutral terminal block. After processing is completed and the limiting effect on the neutral terminal block is released, the first spring 58 will use its elastic potential energy to return the placement table 51 to its original position for future use.

[0042] When coolant is needed for drilling and tapping the neutral terminal block, the outflowing coolant is blocked by the inclined blocks 73 on both sides, and thus falls from the drain trough 72 into the collection tank 71, thereby achieving the collection of coolant.

[0043] It should be noted that: In this application, an annular groove is provided axially on the inner wall of the threaded cylinder, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68. According to the ASTM D1894 standard test, this effectively suppresses the loosening displacement caused by thread springback.

[0044] To address the technical problem of adsorbing waste debris during drilling and tapping of neutral wire terminal blocks, the present invention employs a debris suction assembly 8, which includes a second limiting block 82 slidably connected inside a support frame 66. The second limiting block 82 has an air vent inside, and a first air duct 81 is uniformly fixedly connected to its surface. The first air duct 81 communicates with the air vent. One end of the first air duct 81, away from the second limiting block 82, is inserted into the neutral wire terminal block. A second air duct 83 is inserted into the end of the air vent, away from the first air duct 81. The second air duct 83 is further away from the second limiting block 82. One end of the limiting block 82 is fixedly connected to a slag collection box 85. A vacuum pump 84 is installed on the surface of the slag collection box 85. When collecting the waste generated by drilling and tapping the neutral terminal block, the vacuum pump 84 is connected to an external power source and started. The first air duct 81 will absorb the waste generated by drilling and tapping. The waste will eventually enter the interior of the second air duct 83 through the air hole of the second limiting block 82, and finally enter the interior of the slag collection box 85. Due to the filter screen inside the slag collection box 85, the waste will eventually remain inside the slag collection box 85, thereby achieving the collection of waste.

[0045] It should be noted that the vacuum pump 84 in this application is prior art, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0046] It should be noted that the motor used in this application is a servo motor with an encoder, which has controllable rotation angle of the motor shaft and high precision. This is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0047] It should be noted that the electric actuator used in this application is prior art, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0048] The present invention is used in the following steps: S1: To facilitate the transition between processes for the neutral terminal block, the terminal block is first conveyed on the surface of the feeding mechanism 10 until it can no longer move. Then, the fourth motor 44 is connected to an external power source and started. The first lead screw 45 rotates, driving the second connecting plate 46 to move through the screw barrel until the finger cylinder 48 is above the neutral terminal block. Then, the second electric push rod 47 is connected to an external power source and started. The finger cylinder 48 moves towards the neutral terminal block until the two clamping plates 49 are on both sides of the neutral terminal block. Then, the finger cylinder 48 is connected to an external power source and started. The two clamping plates 49 move towards the neutral terminal block. Because the clamping plates 49 are fixedly connected to positioning protrusions near the surface of the neutral terminal block, the positioning protrusions insert into the interior of the neutral terminal block, clamping the neutral terminal block simultaneously. At the same time, the neutral terminal block is also positioned so that precise position transfer can be achieved. Then, the second connecting plate 46 will drive the neutral terminal block to move to a position with the extrusion top 91 on the same axis. The extrusion top 91 will make a knock mark on the neutral terminal block. Then, by starting the motor inside the turntable 41, the support column 42 will rotate around the axis of the turntable 41 until it rotates 90 degrees. Then, the cylinder inside the locking mechanism 410 will extend towards the turntable 41 until it limits the turntable 41, so that the turntable 41 rotates 90 degrees precisely each time. Then, the neutral terminal block is drilled and tapped by the drilling bit 28 and the tap 31. Then, it is rotated again so that the processed neutral terminal block is on the same axis as the discharge mechanism 101. Then, the neutral terminal block is placed on the surface of the discharge mechanism 101 by the finger cylinder 48 for discharge. S2: When the finger cylinder 48 conveys the neutral terminal block to a position coaxial with the support frame 11, the finger cylinder 48 releases the limit on the neutral terminal block. The neutral terminal block falls into the receiving groove 52 due to gravity, achieving initial positioning of the neutral terminal block. Then, the fifth motor 55 is connected to an external power source and started. The first guide block 57 slides on the surface of the first guide rail 54 due to the threaded cylinder until it slides below the extrusion top 91. Then, the third electric push rod 62 is connected to an external power source and started. The third connecting plate 65 slides on the surface of the second guide rail 63 via the second guide block 64, causing the two support frames 66 to move closer to the neutral terminal block. The two first limit blocks 67 also move due to the movement of the support frames 66. The internal parts of the positioning frames 69 move closer together until the positioning post 68 is inserted into the hole of the neutral terminal block, thereby achieving precise positioning of the neutral terminal block and preventing it from moving during hammering, drilling, and tapping. After each processing, the fourth electric push rod 611 is connected to an external power source and started. The limiting frame 69 slides on the internal surface of the third guide rail 610, thereby causing the two first limiting blocks 67 to move the neutral terminal block. Due to the limiting of the neutral terminal block by the receiving groove 52, the placement table 51 slides inside the first guide block 57 via the positioning rod 59, thereby adjusting the hole position of the neutral terminal block. After processing is completed and the limiting of the neutral terminal block is released, the first spring 58 will also cause the placement table 51 to return to its original position due to elastic potential energy, making it convenient for the next use. S3: When coolant is needed for drilling and tapping the neutral terminal block, the outflowing coolant will be blocked by the inclined blocks 73 on both sides, and will fall from the drain trough 72 into the collection tank 71, thereby achieving the collection of coolant. S4: When collecting the waste generated from drilling and tapping the neutral terminal block, connect the vacuum pump 84 to the external power supply and start it. The first air duct 81 will absorb the waste generated from drilling and tapping. The waste will eventually enter the interior of the second air duct 83 through the air hole of the second limit block 82, and eventually enter the interior of the slag collection box 85. Due to the filter screen inside the slag collection box 85, it will eventually remain inside the slag collection box 85, thereby achieving the collection of waste. S5: To prevent the drill bit 28 from deflecting during drilling, the neutral terminal block is placed below the extrusion top 91 before drilling. The fifth electric push rod 92 is connected to the external power supply and then started. The connecting column 93 will drive the extrusion top 91 to move towards the neutral terminal block until the extrusion top 91 extrudes a groove into the surface of the neutral terminal block. This way, when the drill bit 28 drills, the drill bit 28 will be limited by the groove, thus preventing deflection during drilling. S6: When drilling holes in the neutral terminal block, the first motor 24 is connected to an external power source and started. The first gear 25 drives the second gear 26 to rotate, which in turn drives the drilling bit 28 to rotate through the spring collet 27. At the same time, the first electric push rod 22 is connected to an external power source and started. The first electric push rod 22 drives the connecting frame 23 to move towards the neutral terminal block. The coolant is sent into the interior of the universal bamboo tube 217 through a hose by an external water pump and finally sprayed onto the surface of the neutral terminal. Since the two drilling bits 28 are staggered and inclined, two holes can be drilled on the surface of the neutral terminal at the same time, thus realizing multi-hole processing of the neutral terminal and speeding up the work efficiency. S7: After all six holes have been processed, the second motor 29 is connected to an external power source and started. The third gear 210 drives the fourth gear 211 to rotate, which causes the linkage block 213 to drive the guide rod 216 to slide inside the positioning groove 212. This causes the connecting frame 23 to indirectly drive the two drilling bits 28 to rotate around the center of the connecting frame 23 until they are limited by the positioning groove 212. The second motor 29 is then turned off. Then, the electromagnetic lock 215 is connected to an external power source and started. The extension shaft of one of the electromagnetic locks 215 is inserted into the positioning block 214, which limits the position of the drilling bit 28 and allows the drilling bit 28 to rotate, so that the remaining holes can be processed. S8: When it is necessary to tap the neutral terminal, the third motor 33 is connected to the external power supply and started. The torque limiter 32 will indirectly drive the tap 31 to rotate. Then, the tap 31 is raised and lowered in the same way as drilling to tap. Then, the hole position is switched in the same way as drilling, thereby realizing the tapping of the neutral terminal. S9: When the torque of tap 31 is too high due to a sudden cause during tapping, in order to prevent the third motor 33 from being damaged due to overload, the torque limiter 32 will be triggered, the transmission chain will actively disconnect at the set overload point, thereby disconnecting the third motor 33 from tap 31, and then stopping the output shaft of the third motor 33, causing the torque limiter 32 to re-engage, and then unwinding the tap by flipping, and then tapping again.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
