Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling equipment for manufacturing and positioning explosion-proof cable connectors. Background Technology

[0002] Explosion-proof cable joints are key connection components used in explosive atmospheres. Their core function is to achieve a sealed connection between cables or between cables and equipment, while simultaneously blocking the propagation of explosive energy. Made of high-strength materials such as brass and stainless steel, and precision-machined, they feature internal explosion-proof sealing rings and flameproof surfaces, making them safe for use in flammable and explosive environments such as petroleum, chemical, and coal mines. They are available in various installation methods, including compression and welding types, and are compatible with different cable specifications. They possess dustproof, waterproof, and corrosion-resistant properties, effectively preventing external flammable gases from entering the joint and causing an explosion, thus ensuring the safe operation of electrical systems. One of the core devices in the production of explosion-proof cable joints is a positioning drilling machine, which drills holes in the joint during production.

[0003] In existing explosion-proof cable connector manufacturing positioning drilling equipment, the feeding and automatic positioning clamping processes generally require a feeding device to feed the material, and then a robotic arm to place the explosion-proof cable connector to be drilled into a three-jaw chuck for positioning and clamping. Although this production method can achieve automated drilling, it requires a large number of devices, incurs costs for purchasing equipment, and the increase in equipment also leads to increased maintenance costs in the later stages, thus increasing the manufacturing cost of explosion-proof cable connectors.

[0032] The technical solutions in 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.

[0033] Please see the appendix Figure 1 - Appendix Figure 13 This invention provides a positioning drilling device for manufacturing explosion-proof cable connectors, including a workbench 1. A fixing plate 2 is fixedly connected to one side of the top of the workbench 1. An automatic chuck 3 is fixedly connected to the top of the fixing plate 2. The automatic chuck 3 is used to position and clamp the explosion-proof cable connector. A drilling mechanism 4 is provided on the top of the workbench 1. The drilling mechanism 4 is used to drill holes in the explosion-proof cable connector. A feeding mechanism 5 is provided on one side of the top of the workbench 1. The feeding mechanism 5 is used to feed materials. A blocking mechanism 6 is provided at one end of the automatic chuck 3 near the drilling mechanism 4. The blocking mechanism 6 is used to block the explosion-proof cable connector and prevent it from slipping before clamping. A material discharge mechanism 7 is provided outside the workbench 1. The material discharge mechanism 7 is used to guide the drilled explosion-proof cable connectors to discharge and arrange them neatly. A disassembly and assembly mechanism 8 is provided outside the workbench 1. The disassembly and assembly mechanism 8 is used to install the material discharge mechanism 7.

[0034] The drilling mechanism 4 includes a base plate 401, which provides the mounting position. The bottom of the base plate 401 is fixedly connected to the top of the worktable 1. Slide rails 402 are fixedly connected to both ends of the top of the base plate 401. A mounting seat 403 is slidably connected between the two slide rails 402, allowing the mounting seat 403 to slide on the slide rails 402, thus limiting its movement trajectory. A motor 404 is fixedly connected to the side of the mounting seat 403 away from the automatic chuck 3, providing power for drilling. A drill chuck 405 is rotatably connected to the side of the mounting seat 403 away from the motor 404, clamping the drill bit. A belt is fitted between the output end of the motor 404 and the drill chuck 405. A first motor 406 is fixedly connected to the top of the base plate 401, providing the movement trajectory for the mounting seat 403. A lead screw 407 is fixedly connected to the output end of the first motor 406. After 407 rotates, it can drive the mounting base 403 to move. The external thread of the lead screw 407 is connected to the bottom of the mounting base 403. When drilling, adjust the size between the three jaws of the automatic chuck 3 to be slightly larger than the diameter of the explosion-proof cable connector to be processed. Use the feeding mechanism 5 to place the explosion-proof cable connector to be processed between the three jaws of the automatic chuck 3 and use the blocking mechanism 6 to prevent the explosion-proof cable connector to be processed from falling off. At this time, start the automatic chuck 3 to position and clamp the explosion-proof cable connector to be processed. At this time, start the motor 406. The output end of the motor 406 drives the lead screw 407 to rotate, thereby driving the mounting base 403 to move towards the fixed plate 2. At the same time, start the motor 404. Use the motor 404 as power to drive the drill chuck 405 to rotate, thereby driving the drill bit to rotate, and thus using the drill bit to drill the explosion-proof cable connector to be processed.

[0035] The feeding mechanism 5 includes a mounting box 501, which provides an installation position. A motor 502 is fixedly connected to the outside of the mounting box 501. A limit ring 503 is slidably connected to the inner wall of the mounting box 501, and the limit ring 503 has a limiting function. A movable ring 504 is fixedly connected to the side of the limit ring 503 near the drilling mechanism 4. The movable ring 504 can slide out of the interior of the mounting box 501, thereby extending the space of the mounting box 501. A baffle plate 505 is fixedly connected to the side of the movable ring 504 near the drilling mechanism 4. A rotating inner box 506 is rotatably connected inside the mounting box 501. A limit ring 507 is slidably connected to the inner wall of the rotating inner box 506, and the limit ring 507 has a limiting function. A movable ring 508 is fixedly connected to one end of the limiting ring 507 near the shielding plate 505. The movable ring 508 extends the space of the rotating inner box 506. The end of the movable ring 508 away from the limiting ring 507 is rotatably connected to one side of the shielding plate 505. The shielding plate 505 and the movable ring 508 can form a sealed space. The top of the rotating inner box 506, the movable ring 508, the mounting box 501, and the movable ring 504 are all provided with loading ports 509. The loading ports 509 facilitate the loading of the explosion-proof cable connectors to be processed. The bottom of the mounting box 501 and the movable ring 504 are provided with discharge ports 510. When the loading port 509 is aligned with the discharge port 510, the explosion-proof cable connector can be released. The larger the overlapping opening, the larger the diameter of the explosion-proof cable connector that can be released. Two baffle plates 511 are fixedly connected to the notch of the moving ring 508 and the top notch of the movable ring 504. The baffle plates 511 can block the moving ring 508, preventing it from rotating and causing the loading port 509 to misalign. An outer discharge box 512 is fixedly connected to the bottom of the mounting box 501, and an inner discharge box 513 is fixedly connected to the bottom of the movable ring 504. The space formed by the outer discharge box 512 and the inner discharge box 513 can guide the explosion-proof cable connector to be processed to slide out. The inner discharge box 513 is slidably connected inside the outer discharge box 512. A fixing post 514 is fixedly connected to the bottom of the mounting box 501. Mounting box 501 can be installed in 514. The bottom of mounting post 514 is fixedly connected to the top of workbench 1. The output end of motor 502 is fixedly connected to the middle of the side of rotating inner box 506 away from shielding plate 505. The output end of motor 502 is rotatably connected to the middle of the side of mounting box 501 away from shielding plate 505. When feeding explosion-proof cable connectors to be processed, firstly, multiple explosion-proof cable connectors to be processed are placed into the interior of rotating inner box 506 through loading port 509. Then, motor 502 is started. After the output end of motor 502 rotates, it can drive rotating inner box 506 to rotate, thereby driving limit ring 507 and moving ring 508 to rotate. At the same time, due to the obstruction of baffle plate 511,This ensures that the limiting ring 507 and the moving ring 508 do not rotate when the inner rotating box 506 rotates, thus maintaining the alignment of the loading port 509 between the inner rotating box 506 and the moving ring 508 and preventing misalignment. When the loading port 509 between the inner rotating box 506 and the limiting ring 507 rotates to the discharge port 510, the inner rotating box 506 rotates slowly. When the opening at the overlap of the loading port 509 and the discharge port 510 on the inner rotating box 506 is slightly larger than the diameter of the explosion-proof cable connector to be processed, the explosion-proof cable connector can fall from the opening at the overlap of the loading port 509 and the discharge port 510 on the inner rotating box 506 and enter the interior of the outer discharge box 512 and the inner discharge box 513, thereby guiding the explosion-proof cable connector to be processed between the three jaws of the automatic chuck 3, thus completing the loading process.

[0036] The blocking mechanism 6 includes three fixed cylinders 601, which provide installation positions. The three fixed cylinders 601 are respectively fixedly connected to the outside of the three jaws of the automatic chuck 3. An inner cylinder 602 is slidably connected inside the fixed cylinders 601, sliding within the fixed cylinders 601. A tension spring 603 is installed inside the inner cylinder 602. A stop plate 604 is fixedly connected to the side of the inner cylinder 602 away from the automatic chuck 3. A folding rod 605 is fixedly connected between the three stop plates 604. The folding rod 605 allows one stop plate 604 to move, thereby moving the other two stop plates 604. A baffle 606 is fixedly connected to the bottom end of two jaws of the automatic chuck 3, serving as a blocking mechanism to prevent the explosion-proof cable connector from falling off. One end of the tension spring 603 is fixedly connected to the inner wall of the fixed cylinder 601, and the other end is fixedly connected to the inner wall of the inner cylinder 602. The explosion-proof cable connector to be processed... When the cable connector falls between the three jaws of the automatic chuck 3, the blocking plate 604 prevents the explosion-proof cable connector to be processed from sliding out of the three jaws of the automatic chuck 3. At the same time, the automatic chuck 3 is activated, so that the size between the three jaws of the automatic chuck 3 is slightly larger than the diameter of the explosion-proof cable connector to be processed. This allows the explosion-proof cable connector to be processed to slide into the three jaws of the automatic chuck 3 along the outer wall of the two jaws equipped with the baffle 606. Under the blocking of the baffle 606, the explosion-proof cable connector to be processed will not fall out of the three jaws of the automatic chuck 3. When the three jaws move, the folding rod 605 can be folded, so the folding rod 605 will not interfere with the movement between the three jaws of the automatic chuck 3. After the automatic chuck 3 is activated, the three jaws of the automatic chuck 3 will move towards the middle, thereby clamping the explosion-proof cable connector to be processed between the three jaws. Thus, when clamping the explosion-proof cable connector to be processed, the positioning of the explosion-proof cable connector to be processed can also be completed.

[0037] The material unloading mechanism 7 includes a fixed arrangement box 701, to which a movable arrangement box 702 is slidably connected. The fixed arrangement box 701 and the movable arrangement box 702 can form a space for temporary storage of explosion-proof cable connectors. A first limiting plate 703 is fixedly connected to one side of the fixed arrangement box 701, and a second limiting plate 704 is fixedly connected to the outside of the movable arrangement box 702. The second limiting plate 704 can slide inside the first limiting plate 703, thereby increasing the sliding stability between the fixed arrangement box 701 and the movable arrangement box 702. The second limiting plate 704 is slidably connected inside the first limiting plate 703. Unloading outer boxes 705 are fixedly connected to both sides of the top of the workbench 1. An inner unloading box 706 is slidably connected inside the outer unloading box 705. The unloading inner box 706 and the unloading inner box 706 form a track to guide the explosion-proof cable connector to slide down. A snap-fit ​​buckle 707 is fixedly connected to the outside of the unloading inner box 706. The snap-fit ​​buckle 707 can drive the moving box 702 to reset. A connecting rod 708 is fixedly connected between the two unloading inner boxes 706. The connecting rod 708 can drive the other unloading inner box 706 to move when one unloading inner box 706 moves. A driving rod 709 is fixedly connected to the outside of one of the unloading inner boxes 706. The driving rod 709 can drive the discharge inner box 513 and one of the unloading inner boxes 706 to move. The top of the driving rod 709 is fixedly connected to the outside of the discharge inner box 513. A hydraulic cylinder 710 is fixedly connected to the fixing plate 2. The output end of the hydraulic cylinder 710 is fixedly connected to... Outside the driving rod 709, a buffer spring 712 is fixedly connected to the bottom of the interior of the arranging fixed box 701. A sliding buffer plate 711 is fixedly connected to the top of the buffer spring 712. The sliding buffer plate 711 can hold an explosion-proof cable connector on its top. The buffer spring 712 has a buffering effect. The buffer spring 712 can use its own reaction force to ensure that the finished explosion-proof cable connector is always at the top of the space formed by the arranging moving box 702 and the arranging fixed box 701, preventing the explosion-proof cable connector from falling directly into the bottom of the space formed by the arranging fixed box 701 and the arranging moving box 702, thus preventing damage to the explosion-proof cable connector. The sliding buffer plate 711 is slidably connected to the interior of the arranging fixed box 701, and one corner of the top of the arranging moving box 702 is engaged with the locking mechanism. Inside the buckle 707, two limiting grooves 713 are provided on the inner side of the fixed box 701. The limiting grooves 713 can maintain the stability of the sliding buffer plate 711. The two ends of the sliding buffer plate 711 are slidably connected to the inside of the two limiting grooves 713 respectively. When the drilling of the explosion-proof cable connector to be processed is completed, the automatic chuck 3 is activated, so that the three jaws of the automatic chuck 3 unfold outward. At this time, the baffle 606 will not block the explosion-proof cable connector and can slide into the space formed by the two unloading outer boxes 705 and the unloading inner box 706. It then slides into the space formed by the fixed box 701 and the moving box 702. At this time, the explosion-proof cable connector that has finished drilling will fall on the sliding buffer plate 711.Because a buffer spring 712 is installed below the sliding buffer plate 711, the explosion-proof cable connector will not fall directly into the bottom of the arranging box 701, thus preventing damage. As the number of explosion-proof cable connectors entering the space of the arranging box 701 and the arranging moving box 702 increases, the buffer spring 712 will be compressed under the action of gravity, ensuring that the topmost explosion-proof cable connector is on top of the arranging box 701, so that subsequent falling explosion-proof cable connectors will not be damaged due to excessive drop.

[0038] The assembly / disassembly mechanism 8 includes two mounting blocks 801, which are fixedly connected to the outer sides of the workbench 1. Two insert rods 802 are slidably connected to one side of each mounting block 801. A round handle 803 is fixedly connected to one end of each insert rod 802. A tension spring 804 is sleeved on the outside of each insert rod 802, and the round handle 803 enables the tension spring 804 to function. An installation slider 805 is slidably connected inside each mounting block 801. After the installation slider 805 is installed inside the mounting block 801, the mounting box 701 can be installed. Two insertion holes 806 are provided on one side of the installation slider 805. After being inserted into the socket 806, the mounting slider 805 can be fixed inside the mounting block 801. The insertion rod 802 is inserted into the socket 806. The side of the mounting slider 805 away from the worktable 1 is fixedly connected to the outside of the arranging fixed box 701. One end of the tension spring 804 is fixedly connected to the side of the round handle 803 near the mounting block 801, and the other end of the tension spring 804 is fixedly connected to the outside of the mounting block 801. A pull handle 807 is fixedly connected between the two round handles 803. The outside of both insertion rods 802 are slidably connected to the outer wall of the mounting block 801. When the arranging fixed box 701 and the arranging moving box 702 are assembled... After the space is filled with explosion-proof cable connectors, the handle 807 is moved away from the mounting block 801. This causes the round handle 803 and the insertion rod 802 to move with the handle 807, and stretches the tension spring 804. When the insertion rod 802 moves out of the insertion hole 806, the arranging box 701 can be pulled down, thereby pulling the mounting slider 805 out of the insertion rod 802. This allows the arranging box 701 and the arranging box 702, which are filled with explosion-proof cable connectors, to be disassembled, facilitating the removal of the explosion-proof cable connectors arranged inside the arranging box 701 and the installation of the arranging box. When arranging the fixed box 701 and the moving box 702, align the mounting slider 805 with the inside of the mounting block 801, pull the handle 807 away from the mounting block 801, and pull the insertion rod 802 out of the mounting block 801. After sliding the mounting slider 805 into the mounting block 801, align the insertion hole 806 with the insertion rod 802, release the handle 807, and under the action of the tension spring 804, pull the round handle 803 to reset, thereby driving the handle 807 and the insertion rod 802 to reset, and then allowing the insertion rod 802 to be reinserted into the insertion hole 806, thus completing the installation of the fixed box 701 and the moving box 702.

[0039] Working principle: When drilling, adjust the size between the three jaws of the automatic chuck 3 to be slightly larger than the diameter of the explosion-proof cable connector to be processed. Use the feeding mechanism 5 to place the explosion-proof cable connector to be processed between the three jaws of the automatic chuck 3 and use the blocking mechanism 6 to prevent the explosion-proof cable connector to be processed from falling off. At this time, start the automatic chuck 3 to position and clamp the explosion-proof cable connector to be processed. At this time, start the motor 406. The output end of the motor 406 drives the lead screw 407 to rotate, which can drive the mounting base 403 to move towards the fixed plate 2. At the same time, start the motor 404. Use the motor 404 as power to drive the drill chuck 405 to rotate, which can drive the drill bit to rotate, and use the drill bit to drill the explosion-proof cable connector to be processed.

[0040] When loading the explosion-proof cable connectors to be processed, firstly, multiple explosion-proof cable connectors are placed into the rotating inner box 506 through the loading port 509. Then, motor 2 502 is started. The output of motor 2 502 rotates, driving the rotating inner box 506 to rotate, which in turn drives the limiting ring 507 and the moving ring 508 to rotate. Simultaneously, due to the obstruction of the baffle plate 511, the limiting ring 507 and the moving ring 508 will not rotate while the rotating inner box 506 is rotating. This ensures that the loading ports 509 of the rotating inner box 506 and the moving ring 508 are always aligned, preventing misalignment. When the loading port 509 between the inner rotating box 506 and the limiting ring 507 rotates to the discharge port 510, the inner rotating box 506 rotates slowly. When the opening of the overlapping part of the loading port 509 and the discharge port 510 on the inner rotating box 506 is slightly larger than the diameter of the explosion-proof cable connector to be processed, the explosion-proof cable connector to be processed can fall from the opening of the overlapping part of the loading port 509 and the discharge port 510 on the inner rotating box 506 and enter the interior of the discharge outer box 512 and the discharge inner box 513, so that the explosion-proof cable connector to be processed can be guided between the three jaws of the automatic chuck 3, thereby completing the loading.

[0041] When the explosion-proof cable connector to be processed falls between the three jaws of the automatic chuck 3, it will not slide out of the three jaws of the automatic chuck 3 due to the obstruction of the stop plate 604. At the same time, the automatic chuck 3 is activated so that the size between the three jaws of the automatic chuck 3 is slightly larger than the diameter of the explosion-proof cable connector to be processed. This allows the explosion-proof cable connector to be processed to slide into the three jaws of the automatic chuck 3 along the outer wall of the two jaws with the baffle 606 installed. Under the obstruction of the baffle 606, the explosion-proof cable connector to be processed will not fall out of the three jaws of the automatic chuck 3. When the three jaws move, the folding rod 605 can be folded, so the folding rod 605 will not interfere with the movement between the three jaws of the automatic chuck 3. After the automatic chuck 3 is activated, the three jaws of the automatic chuck 3 will move towards the middle, thereby clamping the explosion-proof cable connector to be processed between the three jaws. This clamping of the explosion-proof cable connector to be processed also completes the positioning of the explosion-proof cable connector to be processed.

[0042] After the drilling of the explosion-proof cable connector is completed, the automatic chuck 3 is activated, causing the three jaws of the automatic chuck 3 to unfold outward. At this time, the baffle 606 will not block the explosion-proof cable connector and can slide into the space formed by the two unloading outer boxes 705 and the unloading inner box 706. It then slides into the space formed by the unloading outer box 705 and the unloading inner box 706 and the arranging fixed box 701 and the arranging moving box 702. At this time, the explosion-proof cable connector that has finished drilling will fall on the sliding buffer plate 711. Since the buffer spring 712 is set below the sliding buffer plate 711, the explosion-proof cable connector will not fall directly into the bottom of the arranging fixed box 701, so as not to break the explosion-proof cable connector. As the number of explosion-proof cable connectors entering the space of the arranging fixed box 701 and the arranging moving box 702 increases, the buffer spring 712 will be compressed under the action of gravity, so that the topmost explosion-proof cable connector is on the top of the arranging fixed box 701, so that the explosion-proof cable connectors that fall later will not be broken due to the large drop.

[0043] When hydraulic cylinder 710 is activated, its output end extends, causing the driving rod 709 to move away from the fixed plate 2. This, in turn, moves the discharge inner box 513 away from the fixed plate 2. Simultaneously, the discharge inner box 513 moves the movable ring 504 away from the fixed plate 2, extending it out of the mounting box 501. This also moves the movable ring 508 out of the rotating inner box 506, allowing a longer explosion-proof cable connector to be inserted into the rotating inner box 506. Simultaneously, the driving rod 709... 09 can also move the unloading inner box 706 away from the fixed plate 2, and through the connecting rod 708, move another unloading inner box 706 away from the fixed plate 2, thus catching longer explosion-proof cable connectors. When the discharge inner box 513 and the unloading inner box 706 move away from the fixed plate 2, they can move two of the blocking plates 604 away from the fixed plate 2, so that the blocking plates 604 can block the explosion-proof cable connectors while also accommodating the length of the explosion-proof cable connectors. At the same time, the folding rod 605 can move another... The stop plate 604 moves away from the fixed plate 2, which in turn moves the inner cylinder 602 away from the fixed plate 2 and stretches the tension spring 603. When the discharge inner box 513 and the unloading inner box 706 move closer to the fixed plate 2, the stop plate 604, without obstruction, can reset the inner cylinder 602 under the reaction force of the tension spring 603. This resets the stop plate 604, which in turn resets the folding rod 605. Simultaneously, when the unloading inner box 706 moves away from the fixed plate 2, it can also reset the arranging moving box 702. Moving away from the fixed plate 2, it can lengthen the space formed by the fixed box 701 and the moving box 702, and temporarily store a longer explosion-proof cable connector. When the output end of the hydraulic cylinder 710 retracts, it can drive the driving rod 709 to move towards the fixed plate 2, and then drive the unloading inner box 706 and the discharge inner box 513 to move towards the fixed plate 2. Thus, the discharge inner box 513 can drive the moving ring 504, the limiting ring 503, the moving ring 508, and the limiting ring 507 to reset. At the same time, the snap fastener 707 can drive the moving box 702 to reset.

[0044] Once the space formed by the fixed box 701 and the moving box 702 is full of explosion-proof cable connectors, the handle 807 is moved away from the mounting block 801. This causes the round handle 803 and the insertion rod 802 to move with the handle 807, stretching the tension spring 804. When the insertion rod 802 moves out of the insertion hole 806, the fixed box 701 can be pulled downwards, thereby pulling the mounting slider 805 out of the insertion rod 802. This allows the fixed box 701 and the moving box 702, now full of explosion-proof cable connectors, to be disassembled, facilitating the removal of the explosion-proof cable connectors arranged inside the fixed box 701. When installing the fixed box 701 and the moving box 702, align the mounting slider 805 with the inside of the mounting block 801, pull the handle 807 away from the mounting block 801, and pull the insertion rod 802 out of the mounting block 801. After sliding the mounting slider 805 into the mounting block 801, align the insertion hole 806 with the insertion rod 802, release the handle 807, and under the action of the tension spring 804, pull the round handle 803 to reset, thereby driving the handle 807 and the insertion rod 802 to reset, and then allowing the insertion rod 802 to be reinserted into the insertion hole 806, thus completing the installation of the fixed box 701 and the moving box 702.
