Description

Technical Field

[0001] This invention relates to the field of composite sleeve production technology, and specifically to an automatic gripping mechanism for conductive rods in composite sleeves. Background Technology

[0002] Composite bushings are cable conduits made of a combination of various materials, primarily used for the external protection of cables. These bushings are typically composed of a combination of materials such as fiberglass and silicone rubber, chosen to provide excellent insulation, corrosion resistance, and flame retardancy. Due to their superior performance in multiple aspects, composite bushings are widely used in power distribution systems, including power transmission and distribution, coal mining, municipal construction, and electrical equipment industries.

[0003] In the composite bushing based on the lead wire of the power capacitor, a conductive rod is installed inside the composite bushing. Therefore, in the manufacturing process of the composite bushing, it is necessary to assemble the conductive rod. The conductive rod mainly undertakes the task of conducting electricity in the composite bushing. It is the medium for current transmission and ensures that power or signals can pass through the bushing smoothly.

[0004] When assembling the conductive rods in composite sleeves, manual labor is usually employed. This reduces production efficiency and, due to the high temperature of the conductive rods, poses a risk of burns to workers during assembly, compromising their safety. While robotic arms are now used, their length and weight make them prone to instability and wobbling when handled by a single robotic arm, further hindering assembly. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic gripping mechanism for composite sleeve conductive rods to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic gripping mechanism for composite sleeve conductive rods, including a mounting frame, and further including: a first sliding seat and a second sliding seat, which are driven by a driving component and slid collinearly and in opposite directions on the mounting frame; gripping components are fixedly mounted on the bottom surfaces of the first sliding seat and the second sliding seat.

[0007] Furthermore, a telescopic cylinder is fixedly installed on the top surface of the mounting bracket, and the output end of the telescopic cylinder is fixedly installed on the first sliding seat.

[0009] Furthermore, two slide rails are fixedly installed on the mounting bracket, and the first rack and the second rack are slidably disposed on the two slide rails respectively.

[0010] Furthermore, the second gear has a ratchet inside, which is fixedly mounted on the rotating shaft, and the second gear also has a pawl inside that cooperates with the ratchet.

[0011] Furthermore, a fixed frame is also fixedly installed on the mounting bracket, and a guide plate is slidably inserted inside the fixed frame. The guide plate is fixedly installed on the second sliding seat, and a first elastic element is provided between the guide plate and the fixed frame. An insert plate is slidably inserted on the side wall of the fixed frame, and a slot adapted to the insert plate is opened on the guide plate.

[0012] Furthermore, the insert plate is provided with an oblique sliding groove, and a fixing rod is slidably arranged inside the oblique sliding groove, and the fixing rod is fixedly installed on the first sliding seat.

[0013] Furthermore, the gripping component includes a finger cylinder, on the bottom surface of which two sliders are collinearly and sliding in opposite directions.

[0017] 3. By utilizing the gripping mechanism, the gripping direction of the claws at both ends of the rotating block can be deflected according to the different inclined surfaces of the conductive rod, thereby further improving the stability of the gripping mechanism in the process of holding the conductive rod.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-8 The present invention provides an automatic gripping mechanism for a composite sleeve conductive rod, including a mounting frame 1, and further including: a first sliding seat 2 and a second sliding seat 3, which are driven by a driving component 4 and are collinearly and slidably disposed on the mounting frame 1; a gripping component 5 is fixedly installed on the bottom surface of both the first sliding seat 2 and the second sliding seat 3.

[0023] In the above technical solution, by adjusting the distance between the first sliding seat 2 and the second sliding seat 3 on the mounting bracket 1, the gripping mechanism on the first sliding seat 2 and the second sliding seat can grip conductive rods of different lengths, thereby improving the stability of the conductive rod when it is clamped to a certain extent.

[0024] As a preferred technical solution of this embodiment, a telescopic cylinder 401 is fixedly installed on the top surface of the mounting bracket 1, and the output end of the telescopic cylinder 401 is fixedly installed on the first sliding seat 2.

[0025] Furthermore, a rotating shaft 402 is rotatably mounted on the mounting frame 1, and a first gear 403 and a second gear 404 are fixedly mounted on the circumferential surface of the rotating shaft 402 respectively; a first rack 407 and a second rack 408 are slidably mounted on the mounting frame 1, and a first sliding seat 2 and a second sliding seat 3 are fixedly mounted on the first rack 407 and the second rack 408 respectively, and the first rack 407 and the second rack 408 mesh with the first gear 403 and the second gear 404 respectively.

[0026] In the above technical solution, by utilizing the telescopic cylinder 401 on the mounting frame 1, the first sliding seat 2 can move under the action of the telescopic cylinder 401. During the movement of the first sliding seat 2, the interaction between the first gear 403 and the first rack 407 causes the rotating shaft 402 on the mounting frame 1 to rotate, thereby causing the second gear 404 on the rotating shaft 402 to rotate. By utilizing the interaction between the second gear 404 and the second rack 408, the second sliding seat 3 can move in the opposite direction to the movement direction of the first sliding seat 2, thereby achieving the effect of adjusting the distance between the first sliding seat 2 and the second sliding seat 3.

[0027] As a preferred technical solution in this embodiment, two slide rails are fixedly installed on the mounting bracket 1, and the first rack 407 and the second rack 408 are slidably arranged on the two slide rails respectively.

[0028] In the above technical solution, by utilizing the slide rail on the mounting bracket 1, the sliding direction of the first rack 407 and the second rack 408 can be restricted.

[0029] As a preferred technical solution of this embodiment, the second gear 404 is provided with a ratchet 405 inside, the ratchet 405 is fixedly installed on the rotating shaft 402, and the second gear 404 is also provided with a pawl 406 that cooperates with the ratchet 405 inside.

[0030] In the above technical solution, by utilizing ratchet 405 and pawl 406, when the telescopic cylinder 401 retracts and the first sliding seat 2 moves back, the first rack 407 and the first gear 403 cooperate to rotate the shaft 402 on the mounting bracket 1. Due to the action of ratchet 405 and pawl 406, the second gear 404 on the shaft 402 stops rotating. Therefore, when the first sliding seat 2 slides back, the second sliding seat 3 is not restricted by the movement of the first sliding seat 2, thus achieving the effect of automatically feeding the clamped conductive rod.

[0031] As a preferred technical solution of this embodiment, a fixing frame 409 is also fixedly installed on the mounting frame 1. A guide plate 410 is slidably inserted inside the fixing frame 409. The guide plate 410 is fixedly installed on the second sliding seat 3, and a first elastic member 411 is provided between the guide plate 410 and the fixing frame 409. An insert plate 412 is slidably inserted on the side wall of the fixing frame 409. A slot adapted to the insert plate 412 is opened on the guide plate 410, and a second elastic member 413 is provided between the insert plate 412 and the fixing frame 409.

[0032] In the above technical solution, when the second sliding seat 3 moves under the drive of the first sliding seat 2, the guide plate 410 in the fixed frame 409 can slide against the elastic force of the first elastic member 411. After the second sliding seat 3 moves to an appropriate position, the insert plate 412 on the fixed frame 409 can be inserted into the slot opened on the guide plate 410 under the action of the second elastic member 413, thereby achieving the effect of locking the position of the slid-out second sliding seat 3.

[0033] As a preferred technical solution of this embodiment, the insert plate 412 is provided with an inclined slide groove 415, and a fixing rod 414 is slidably arranged inside the inclined slide groove 415. The fixing rod 414 is fixedly installed on the first sliding seat 2.

[0034] In the above technical solution, by utilizing the fixing rod 414 on the first sliding seat 2, when the first sliding seat 2 slides back under the action of the telescopic cylinder 401, the cooperation between the fixing rod 414 and the inclined slide groove 415 allows the insert plate 412 to move away from the guide plate 410, thereby allowing the insert plate 412 to be removed from the slot opened on the guide plate 410. At this time, by using the elastic force of the first elastic element 411, the second sliding seat 3 can move back, thereby achieving the effect of resetting the second sliding seat 3.

[0035] As a preferred technical solution of this embodiment, the gripping component 5 includes a finger cylinder 51. Two sliders 52 are collinearly and sliding in opposite directions on the bottom surface of the finger cylinder 51. A connecting rod 53 is fixedly installed on each of the two sliders 52. A first rotating rod 54 is rotatably installed on each of the two connecting rods 53. An adjusting plate 55 is rotatably installed on the first rotating rod 54. A second rotating rod 56 is rotatably installed at each corresponding end of the adjusting plate 55. A torsion member is provided between the second rotating rod 56 and the adjusting plate 55. A rotating block 57 is fixedly installed on the circumference of the second rotating rod 56. A gripper 58 is fixedly installed on the rotating block 57.

[0036] In the above technical solution, by using the finger cylinder 51, the two sliders 52 on the bottom surface of the finger cylinder 51 can slide in opposite directions along the same line under the action of the finger cylinder 51, thereby driving the two connecting rods 53 to slide. At this time, by using the rotating block 57 on the adjusting plate 55, when the gripper 58 comes into contact with the surface of the conductive rod, the rotating block 57 can overcome the torsional force of the torsion member and rotate, thereby driving the gripper 58 to rotate slightly, so that the contact surface between the gripper 58 and the conductive rod is in a matching state, thereby improving the stability of the gripper 58 in the process of holding the conductive rod.

[0037] As a preferred technical solution of this embodiment, an anti-slip pad 59 is fixedly installed on the surface of the gripper 58. The anti-slip pad 59 is a rubber pad.

[0038] In the above technical solution, by using a rubber pad, the friction between the gripper 58 and the contact surface of the conductive rod is increased, thereby further improving the stability of the gripper 58 in the process of holding the conductive rod.

[0039] Working principle: Before gripping the conductive rod, the first sliding seat 2 moves under the action of the telescopic cylinder 401 on the mounting frame 1. During the movement of the first sliding seat 2, the first gear 403 and the first rack 407 cooperate to rotate the shaft 402 on the mounting frame 1, which in turn rotates the second gear 404 on the shaft 402. The second gear 404 and the second rack 408 cooperate to move the second sliding seat 3 in the opposite direction to the movement of the first sliding seat 2, thereby adjusting the distance between the first sliding seat 2 and the second sliding seat 3. This allows the gripping components 5 on the first sliding seat 2 and the second sliding seat 3 to clamp the long conductive rod. When the second sliding seat 3 moves under the drive of the first sliding seat 2, the guide plate 410 in the fixed frame 409 can slide against the elastic force of the first elastic member 411. After the second sliding seat 3 moves to the appropriate position, the insert plate 412 on the fixed frame 409 can be inserted into the slot opened on the guide plate 410 under the action of the second elastic member 413, thereby achieving the effect of locking the position of the slid-out second sliding seat 3. After the distance between the first sliding seat 2 and the second sliding seat 3 is adjusted, the gripping component 5 is used to make the two sliders 52 on the bottom surface of the finger cylinder 51 slide in the opposite direction along the same line under the action of the finger cylinder 51, thereby driving the two connecting rods 53 to slide. At this time, the rotating block 57 on the adjusting plate 55 is used to make the gripper 58 contact the surface of the conductive rod. The rotating block 57 can overcome the torsional force of the torsion member and rotate, thereby driving the gripper 58 to rotate slightly, so that the contact surface between the gripper 58 and the conductive rod is in a matching state, so that the gripper 58 can effectively clamp the arc surface of the conductive rod. After the conductive rod is clamped, the ratchet 405 and pawl 406 are used to ensure that when the telescopic cylinder 401 retracts and the first sliding seat 2 moves back, the first rack 407 and the first gear 403 cooperate to make the rotating shaft 402 on the mounting frame 1 rotate. Due to the action of the ratchet 405 and pawl 406, the second gear 404 on the rotating shaft 402 stops rotating. Therefore, when the first sliding seat 2 slides back, the second sliding seat 3 is not restricted by the movement of the first sliding seat 2, thus achieving the effect of automatically feeding the clamped conductive rod. When the first sliding seat 2 moves back under the action of the telescopic cylinder 401, the fixed rod 414 on the first sliding seat 2 allows the insertion plate 412 to move away from the guide plate 410 during the sliding back motion of the first sliding seat 2 under the action of the telescopic cylinder 401. This allows the insertion plate 412 to be removed from the slot on the guide plate 410. At this time, the elastic force of the first elastic element 411 allows the second sliding seat 3 to move back, thereby achieving the effect of resetting the second sliding seat 3. The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
