Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and more specifically, to a composite surge arrester core assembly equipment. Background Technology

[0002] Composite surge arrester core assembly equipment is used to stack and press together components such as zinc oxide resistor sheets, electrode sheets, and fasteners through automatic feeding, stacking and positioning, and pressing to form composite surge arrester cores. The final product is a surge arrester core assembly with a dense structure and reliable electrical connection, which is used to provide components for the assembly of composite surge arresters.

[0003] During the assembly of the composite surge arrester core, zinc oxide resistor sheets need to be clamped one by one and transported to a predetermined position for stacking and pressing. However, due to the outer diameter tolerance between resistor sheets, it is difficult to keep the contact area and stress state completely consistent during clamping. The clamping speed and clamping force are not easy to control precisely. The resistor sheet material itself is relatively brittle. When the clamping speed is too fast, the clamping force is too large, and the gripping stroke is inconsistent, the edge of the resistor sheet is very easy to break or be damaged due to local stress concentration. This not only affects the stacking density between resistor sheets, but also damages the uniformity of electrical connection inside the core, reducing the overall assembly quality of the composite surge arrester core. Summary of the Invention

The gripping auxiliary mechanism is located at the lower end of the gripping claws. The gripping auxiliary mechanism includes gripping fingers rotatably connected to the bottom end of the gripping claws. Two first brackets are fixedly connected to the lower ends of the two gripping claws on opposite sides. A first connecting cylinder is slidably sleeved on the longitudinal arm end of the first bracket. A pad is fixedly connected to the bottom end of the first connecting cylinder. A first support arm is fixedly connected to the upper ends of the two gripping fingers on opposite sides. A support shaft is rotatably connected between the two first support arms.

[0006] Furthermore, a lower support plate is fixedly connected between the two first connecting cylinders located on the same gripper, an upper support plate is fixedly connected between the longitudinal arm ends of the two first supports, a first spring is fixedly connected between the upper support plate and the lower support plate, a groove adapted to the support shaft is opened on the lower surface of the pad near the gripper finger, the lower surface of the pad away from the gripper finger is a slope, and two blocking strips are fixedly connected to the end of the pad away from the gripper finger.

[0007] Furthermore, it also includes an assembly auxiliary mechanism, which is disposed on the side of the assembly table. The assembly auxiliary mechanism includes a second bracket fixedly connected to the side of the assembly table. A guide arm is fixedly inserted inside the second bracket. Two movable plates are slidably sleeved on the surface of the guide arm. A limiting frame is fixedly connected to the surface of each of the two movable plates. Multiple connecting rods are fixedly connected to the lower surface of each of the two limiting frames. A support seat is fixedly connected to the bottom end of each set of connecting rods. A guide plate is fixedly connected to the end of the limiting frame away from the movable plate.

[0008] Furthermore, a third spring is fixedly connected to both sides of the second bracket, and the ends of the two third springs that are far apart from each other are fixedly connected to the surfaces of the two movable plates respectively.

[0009] Furthermore, a first rotating shaft is rotatably connected to the surface of the second bracket, a central transmission arm is rotatably connected to the surface of the first rotating shaft, a third rotating shaft is rotatably connected to both ends of the central transmission arm, a power transmission arm is rotatably connected to the surface of both third rotating shafts, a second rotating shaft is rotatably connected to the end of each of the two power transmission arms away from the central transmission arm, and the two second rotating shafts are respectively rotatably connected to the top ends of the two moving plates.

[0010] Furthermore, a support column is fixedly connected to the upper surface of the assembly table, a hydraulic rod is fixedly connected to the transverse arm end of the support column, a rotating connecting seat is rotatably connected to the power output end of the hydraulic rod, a second support arm is rotatably connected to the lower surface of the rotating connecting seat, an internally threaded sleeve is slidably inserted into the inner end of the second support arm away from the hydraulic rod, a push column is inserted into the inner threaded sleeve, and a push plate is fixedly connected to the bottom end of the push column.

[0011] Furthermore, a motor is fixedly connected to the upper surface of the assembly table, and a second connecting cylinder is fixedly connected to the output shaft of the motor. A vertical arm is slidably inserted inside the second connecting cylinder, and the top end of the vertical arm is fixedly connected to the lower surface of the second support arm near the hydraulic rod.

[0012] Furthermore, a guide hoop is fixedly connected to the upper surface of the limiting frame.

[0013] Furthermore, a support ring is fixedly fitted onto the surface of the internally threaded sleeve, and a second spring is fixedly connected between the support ring and the second support arm.

[0014] Furthermore, the surface of the push post is provided with a spiral groove, and the internal threaded sleeve is threaded onto the surface of the push post through the spiral groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) When the resistor sheet is gripped, if the gripping force is too large or the gripping stroke exceeds the limit and exceeds the resistance range provided by the first spring and the groove, the gripping finger rotates and gradually disengages from the groove, and the pad moves upward. The excessive force is buffered and removed by the rotation of the gripping finger, and the stroke of the gripping finger is increased to prevent damage to the resistor sheet during the gripping process.

[0016] (2) This solution fixes the insulating tube by inserting it into two limiting frames. Through the cooperation of the middle transmission arm and the two power transmission arms, the two limiting frames move synchronously towards each other (closer to each other) or in opposite directions (away from each other), so that the position of the insulating tube is more accurate and fixed each time, reducing the situation where the resistor is misaligned and cannot enter the insulating tube or is tilted and stuck when it is placed later.

[0017] (3) When the push plate encounters resistance when it contacts the resistor, the internal threaded sleeve continues to move downward. When the internal threaded sleeve moves downward, it causes the push column and the push plate to rotate, which in turn drives the resistor in contact with the push plate to rotate. When the resistor is stuck in the insulating cylinder, it is cleared by rotating the resistor and applying pressure.

[0018] (4) When the resistor sheet is stacked and pressed, if the pressure exceeds a certain level and the blockage is still not cleared, the pressure exceeds the bearing capacity of the second spring. The second spring is compressed and no longer pushes the resistor sheet down. The second spring is deformed and in a compressed state to prevent the resistor sheet from being damaged due to excessive pressure. Attached Figure Description

[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] Please see Figures 1-5A composite surge arrester core assembly device includes an assembly platform 1 and a conveying assembly 2. The conveying assembly 2 is mounted on the surface of the assembly platform 1. A slide 3 is fixedly mounted on the upper surface of the assembly platform 1. A gripping assembly 4 is mounted on the surface of the slide 3. Two gripping claws 401 are mounted on the bottom of the gripping assembly 4. The device also includes a gripping auxiliary mechanism located at the lower end of the gripping claws 401. The gripping auxiliary mechanism includes gripping fingers 402 rotatably connected to the bottom end of the gripping claws 401. Two first supports 403 are fixedly connected to the lower ends of the two gripping claws 401 on opposite sides. A first connecting cylinder 410 is slidably sleeved on the longitudinal arm end of the first support 403. A pad 404 is fixedly connected to the bottom end of the first connecting cylinder 410. Each of the gripping fingers 402 has a first support arm 405 fixedly connected to its upper end on the side away from each other. A support shaft 406 is rotatably connected between the two first support arms 405. A lower support plate 411 is fixedly connected between the two first connecting cylinders 410 located on the same gripping claw 401. An upper support plate 408 is fixedly connected between the longitudinal arm ends of the two first brackets 403. A first spring 409 is fixedly connected between the upper support plate 408 and the lower support plate 411. A groove adapted to the support shaft 406 is opened on the lower surface of the pad 404 near the gripping finger 402. The lower surface of the pad 404 away from the gripping finger 402 is an inclined surface. Two blocking strips 407 are fixedly connected to the end of the pad 404 away from the gripping finger 402.

[0023] By adopting the above technical solution, when assembling the resistor sheet, the resistor sheet is transported to the bottom of the gripping component 4 by the conveying component 2. Then, the gripping component 4 moves horizontally on the surface of the slide table 3, so that the two gripping claws 401 are located on both sides of the resistor sheet. Then, the driving component in the gripping component 4 drives the two gripping claws 401 to move towards each other, thereby gripping the resistor sheet. This is a common method in the prior art, and will not be described in detail here.

[0024] When gripping the resistor sheet, if the gripping force is too great or the gripping stroke exceeds the limit, exceeding the resistance range provided by the first spring 409 and the groove, the gripping finger 402 rotates and gradually disengages from the groove. At this time, the pad 404 moves upward, and the first spring 409 is in a compressed state. Since the rotation of the gripping finger 402 can buffer and dissipate excessive force and increase the stroke of the gripping finger 402, damage to the resistor sheet can be prevented during the gripping process. When the two gripping fingers 402 move away from each other to release the resistor sheet, the rebound of the first spring 409 can push the pad 404 downward, and the guide of the inclined surface on the pad 404 can allow the support shaft 406 to return to the groove, realizing the reset of the gripping finger 402. The spring constant of the first spring 409 is defined as follows. The geometric depth of the groove in the 404 pad is set to... The lever arm length from the fulcrum of the grasping finger 402 to the point of force application is... Define the escape critical force. When the clamping force When this occurs, the trip protection is triggered.

[0025] like Figures 6-10 As shown, it also includes an assembly auxiliary mechanism, which is disposed on the side of the assembly table 1. The assembly auxiliary mechanism includes a second bracket 518 fixedly connected to the side of the assembly table 1. A guide arm 519 is fixedly inserted inside the second bracket 518. Two movable plates 520 are slidably sleeved on the surface of the guide arm 519. A limiting frame 516 is fixedly connected to the surface of each of the two movable plates 520. Multiple connecting rods 503 are fixedly connected to the lower surface of each of the two limiting frames 516. A support seat 504 is fixedly connected to the bottom end of each of the two sets of connecting rods 503. A guide plate 515 is fixedly connected to the end of the limiting frame 516 away from the movable plate 520. A third spring 521 is fixedly connected to both sides of the second bracket 518. The ends of the two third springs 521 that are away from each other are respectively fixedly connected to the surfaces of the two movable plates 520.

[0026] The second bracket 518 is rotatably connected to a first rotating shaft 524. The surface of the first rotating shaft 524 is rotatably connected to a middle transmission arm 523. Both ends of the middle transmission arm 523 are rotatably connected to third rotating shafts 526. The surfaces of the two third rotating shafts 526 are rotatably connected to power transmission arms 522. The ends of the two power transmission arms 522 away from the middle transmission arm 523 are rotatably connected to second rotating shafts 525. The two second rotating shafts 525 are respectively rotatably connected to the top ends of the two moving plates 520.

[0027] The assembly table 1 has a support column 501 fixedly connected to its upper surface. A hydraulic rod 505 is fixedly connected to the horizontal arm end of the support column 501. A rotating connecting seat 506 is rotatably connected to the power output end of the hydraulic rod 505. A second support arm 507 is rotatably connected to the lower surface of the rotating connecting seat 506. An internally threaded sleeve 512 is slidably inserted into the end of the second support arm 507 away from the hydraulic rod 505. A pusher 513 is inserted into the internally threaded sleeve 512. A pusher plate 527 is fixedly connected to the bottom end of the pusher 513.

[0028] The assembly table 1 has a motor 502 fixedly connected to its upper surface. The output shaft of the motor 502 is fixedly connected to a second connecting cylinder 509. A vertical arm 508 is slidably inserted inside the second connecting cylinder 509. The top end of the vertical arm 508 is fixedly connected to the lower surface of the second support arm 507 near the hydraulic rod 505. A guide hoop 517 is fixedly connected to the upper surface of the limiting frame 516. The structure and installation position of the guide hoop 517 can guide the resistor sheet as it falls into the cylinder, making the resistor sheet fall more accurately. A support ring 511 is fixedly fitted on the surface of the internal threaded sleeve 512. A second spring 510 is fixedly connected between the support ring 511 and the second support arm 507. A spiral groove 514 is opened on the surface of the push column 513. The internal threaded sleeve 512 is threadedly fitted onto the surface of the push column 513 through the spiral groove 514.

[0029] By adopting the above technical solution, during assembly, the insulating cylinder needs to be inserted between the two guide plates 515 to push the two guide plates 515 apart. At this time, both third springs 521 are in a stretched state, which allows the insulating cylinder to be inserted into the two limiting frames 516. At the same time, the bottom end of the insulating cylinder is located on the two support seats 504, and the two limiting frames 516 are pulled together by the two third springs 521 to fix the insulating cylinder. During the movement of the two limiting frames 516, the cooperation of the middle transmission arm 523 and the two power transmission arms 522 can make the two limiting frames 516 move synchronously in opposite directions and closer to each other, so that the position of the insulating cylinder is more accurate and fixed each time, reducing the occurrence of misalignment and inability to enter the insulating cylinder or tilting and jamming when the resistor is placed later.

[0030] After the resistive sheet is grasped, the grasping component 4 transports the resistive sheet directly above the two limiting frames 516, that is, directly above the insulating cylinder. Then the resistive sheet is released and falls into the insulating cylinder. This process is repeated to stack the resistive sheets in the insulating cylinder.

[0031] After the resistor sheet is placed, the second support arm 507 is driven to rotate by the motor 502, which in turn moves the lower push plate 527 to the top of the insulating cylinder. Then, the hydraulic rod 505 pushes the second support arm 507 and the lower push plate 527 downward, so that the lower push plate 527 enters the insulating cylinder and presses the resistor sheet in the insulating cylinder. When the lower push plate 527 encounters resistance when it contacts the resistor sheet, the internal threaded sleeve 512 continues to move downward. Because the spiral gap and angle of the spiral groove 514 are large, the lower push column 513 and the lower push plate 527 can rotate when the internal threaded sleeve 512 moves downward, which in turn drives the resistor sheet in contact with the lower push plate 527 to rotate. Thus, when the resistor sheet is stuck in the insulating cylinder, the resistor sheet can be unblocked by rotating and pressing the resistor sheet. If the stuck resistor is not cleared even after exceeding a certain pressure, the second spring 510 is subjected to a thrust greater than its set preload and undergoes elastic compression. The second spring 510 is compressed and stops pushing the resistor further down, preventing the resistor from being damaged due to excessive pressure.

[0032] Usage method: The conveying component 2 conveys the resistor sheet to the bottom of the gripping component 4. The gripping component 4 moves horizontally on the surface of the slide table 3 so that the two gripping claws 401 are located on both sides of the resistor sheet. Then the driving component in the gripping assembly 4 drives the two gripping claws 401 to move closer to each other and grip the resistor sheet; When the gripping force is too great or the gripping stroke exceeds the limit and exceeds the resistance range provided by the first spring 409 and the groove, the gripping finger 402 rotates and gradually disengages from the groove, and the pad 404 moves upward. The excessive force is buffered and relieved by the rotation of the gripping finger 402, while the stroke of the gripping finger 402 is increased to prevent damage to the resistor sheet. When the two gripping fingers 402 move away from each other and release the resistor sheet, the first spring 409 rebounds and pushes the pad 404 downward. The support shaft 406 is guided back into the groove by the inclined surface on the pad 404, thus resetting the gripping fingers 402. Insert the insulating cylinder between the two guide plates 515 and push the two guide plates 515 apart. At this time, both third springs 521 are in a stretched state, so that the insulating cylinder is inserted into the two limiting frames 516. The bottom end of the insulating cylinder is located on the two support seats 504. The two third springs 521 pull the two limiting frames 516 together to fix the insulating cylinder. During the movement of the two limiting frames 516, the cooperation of the middle transmission arm 523 and the two power transmission arms 522 enables the two limiting frames 516 to move synchronously in opposite directions and closer to each other, ensuring that the insulating cylinder is accurately fixed in place each time. The gripping component 4 delivers the resistor sheet directly above the two limiting frames 516, that is, directly above the insulating cylinder, and then releases the resistor sheet, which falls into the insulating cylinder. This process is repeated to stack the resistor sheets in the insulating cylinder. After the resistor sheet is placed, the motor 502 drives the second support arm 507 to rotate, which moves the lower push plate 527 to the top of the insulating cylinder. Then the hydraulic rod 505 pushes the second support arm 507 and the lower push plate 527 downward, so that the lower push plate 527 enters the insulating cylinder and presses the resistor sheet in the insulating cylinder. When the push plate 527 encounters resistance when it contacts the resistor piece, the internal threaded sleeve 512 continues to move downward. When the internal threaded sleeve 512 moves downward, it causes the push column 513 and the push plate 527 to rotate, which in turn drives the resistor piece in contact with the push plate 527 to rotate. When the resistor piece is stuck, it is cleared by rotation and pressure. When the pressure exceeds the elastic limit of the second spring 510 and still does not clear the blockage, the second spring 510 is compressed and buffered, and no longer pushes the resistor sheet downwards to prevent the resistor sheet from being damaged due to excessive pressure.
