Description

Technical Field

[0001] This utility model relates to the field of spacer manufacturing technology, and more specifically, to a high-precision automatic pin-plugging device for spacer clamps with a reasonable and ingenious structural design, high precision in pin feeding and pin-plugging action, and stable and reliable operation. Background Technology

[0002] A spacer is a hardware component installed on split conductors to fix the spacing between them, preventing conductors from whipping each other and suppressing aerobatic vibrations and span oscillations. Spacers are typically installed in the middle of the span, with one spacer every 50-60 meters. The spacer clamp is the core component of the spacer.

[0003] The spacer bar clamp mainly consists of a clamp body, a clamp cover, and a pin. Both the clamp cover and the clamp body have pin holes, into which the pin is inserted, thus achieving a flip-type movable connection between the clamp cover and the clamp body. Specifically, the clamp body and the clamp cover are initially assembled so that the pin holes on the clamp body and the clamp cover are aligned. After alignment, a pin hole is formed, and then the pin is inserted into the pin hole.

[0004] Currently, the pin-fitting process largely relies on manual operation, resulting in high costs and low efficiency. To address this issue, Chinese Patent Publication No. CN222359667U (An Automatic Assembly System for Spacer Bar Clamps) proposes an automated installation scheme for spacer bar pins. The automatic pin-pressing device includes a pressure-applying kit, a pin-supplying kit, and a vibration-assisted kit. The pressure-applying kit has a pressure-applying component whose pressure path is adapted to the pin's pressing angle. The pin-supplying kit has a pin-transferring component that displaces the pin to the bottom of the pressure-applying kit. A guide hole is provided below the pin-transferring component, and the inner wall of the guide hole conforms to the pin's movement trajectory in the pressure path. The vibration-assisted kit has a vibration source and a vibration-transmitting component. The vibration-transmitting component has a vibration-receiving end connected to the vibration source and a vibration-transmitting end in contact with the spacer bar clamp. The vibration auxiliary kit is movably mounted on the first fixed bracket. The vibration auxiliary kit includes an inner auxiliary kit and an outer auxiliary kit. The vibration transmission end includes an outer vibration transmission end in the outer auxiliary kit that contacts both sides of the spacer bar clamp, and an inner vibration transmission end in the inner auxiliary kit that contacts the inner wall of the slot in the spacer bar clamp cover plate. When the vibration transmission component has a structure that contacts both ends of the spacer bar clamp, the vibration auxiliary kit needs to be movably mounted on the fixed bracket, meaning the vibration auxiliary kit can move on the fixed bracket. The purpose is that when the spacer bar clamp to be processed moves into the working area of ​​the automatic pressing pin device, the vibration auxiliary kit displaces so that the vibration transmission end of the vibration transmission component can contact the spacer bar clamp; and before and after the pressing pin operation, when the limiting kit carries the spacer bar clamp, the vibration kit moves so that the vibration transmission component does not obstruct the limiting kit from moving the spacer bar clamp. The vibration transmission component includes two sets of auxiliary kits, inner and outer, which can create a combined internal and external vibration. During this process, it provides a certain clamping effect on the spacer bar clamp, preventing excessive vibration amplitude and thus preventing large overall displacement. The inner auxiliary kit acts only on the inner wall of the slot in the wire clamp cover. On one hand, in conjunction with the outer auxiliary kit, it provides partial clamping for the wire clamp cover, ensuring that during vibration, the entire wire clamp cover moves, keeping the connecting through hole on the wire clamp cover vertical and preventing tilting. This ensures that when the pin is pressed down vertically, the bottom end of the pin will not collide with the inner wall of the connecting through hole. On the other hand, this structure provides a stronger vibration effect to the wire clamp cover than to the wire clamp body, ensuring a certain relative positional change between the wire clamp cover and the wire clamp body. During this process, there is a higher probability that the connecting through holes of the two will align, further ensuring the smooth insertion of the pin.

[0005] It is evident that traditional pinning methods have several drawbacks: 1. Complex structural and operational designs, resulting in high implementation costs and poor operational stability; 2. Poor pinning precision, as traditional methods rely on vibration assistance to improve assembly success rates, which is essentially a probabilistic process. This lack of deterministic assembly violates the fundamental requirement of modern manufacturing for process controllability, inevitably leading to high scrap rates and hindering market acceptance.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, a high-precision automatic pin-plugging device for spacer bar wire clamps includes a pin-feeding module 52 with a linear drive assembly 521 installed. A pin converter 523 is provided at one end of the module frame 522 of the pin-feeding module 52 near the feeding mechanism 51. The pin converter 523 includes a sleeve disk 5233 fixedly connected to the rotor of a rotary actuator 5231. A matching groove 5235, adapted to the shape of a sleeve 5234, is formed on the sleeve disk 5233. The sleeve 5234, housed within the groove 5235, is locked by a clamping block 5236 fixed to the sleeve disk 5233. The sleeve 5234 receives the wire clamp pins 33 fed from the feeding mechanism 51. The rotational movement of the rotary actuator 5231 changes the orientation of the wire clamp pins 33 located within the sleeve 5234. A pin conveying cylinder 524 is fixedly installed below the pin converter 523, and the pin conveying cylinder 524 is fixed to the module frame 522 via a conveying cylinder bracket 5241. When the sleeve 5234 is in a vertical state, the pin conveying cylinder 524 and the sleeve 5234 form a coaxial channel for conveying the wire clamp pin 33; a pin receiving device 525 is provided below the pin conveying cylinder 524 to receive and keep the wire clamp pin 33 in a vertical state. A plugging pin assembly 526 is installed at the other end of the module frame 522; the linear drive assembly 521 drives the wire clamp pin 33 in the pin receiving device 525 to move directly below the plugging pin assembly 526. The feeding mechanism 51 uses a high-performance, widely used vibratory feeder 511. Figure 1 As shown, the spacer bar clamp 3, which is composed of the clamp body and the clamp cover, is fixed directly below the plugging pin assembly 526, and the pin hole of the spacer bar clamp 3 to be plugged is in a common central axis relationship with the actuator of the plugging pin assembly 526.

[0035] The operation process in this embodiment is as follows: The feeding mechanism 51 horizontally conveys the wire clamp pin 33 into the sleeve 5234. The rotary actuator 5231 rotates rapidly by 90°. At this time, the sleeve 5234 and the pin conveying cylinder 524 form a coaxial channel for conveying the wire clamp pin 33. The wire clamp pin 33 in the sleeve 5234 passes through the pin conveying cylinder 524 and is received by the pin receiver 525, which clamps the wire clamp pin 33 in a vertical position. Subsequently, the linear drive assembly 521 moves the wire clamp pin 33 directly below the pin-plugging assembly 526. The actuator of the pin-plugging assembly 526 moves vertically downward to smoothly insert the wire clamp pin 33 into the pin-plugging hole, thereby automatically completing the pin-plugging process of the spacer bar wire clamp.

[0036] This embodiment of the pin-plugging device simplifies the mechanical structure and optimizes the operation process, significantly reducing the complexity of the pin-plugging process, improving equipment operational stability and operational flexibility. Furthermore, its high-precision, stable operation makes a significant contribution to completely abandoning the traditional probabilistic assembly method that relies on vibration assistance, ensuring the entire pin-plugging action is entirely deterministic and meets the requirements of modern intelligent manufacturing for process controllability. With its stable and reliable performance, excellent assembly quality, and high production efficiency, this embodiment not only significantly reduces the manufacturing cost of spacer bar clamps and enhances their market competitiveness but also opens up broad market application prospects for the pin-plugging device itself.

[0037] Example 2

[0038] Based on Embodiment 1, this embodiment continues to describe in detail the technical features involved therein and the functions and roles of these technical features in this utility model, so as to help those skilled in the art to fully understand the technical solution of this utility model and reproduce it.

[0039] like Figure 3 , Figure 5 , Figure 6As shown, the pin receiving device 525 in this embodiment includes a pin receiving slide rail 5251 fixedly connected to the pin feeding slider 5211 of the linear drive assembly 521. The linear drive assembly 521 is a rodless cylinder. A pin receiving movable block 5252 is slidably mounted on the pin receiving slide rail 5251. Specifically, a dovetail groove is formed on the pin receiving slide rail 5251, and the pin receiving movable block 5252 is a dovetail slider with a back end adapted to the dovetail groove. The position of the pin receiving movable block 5252 is defined by a limiting plate 5253 fixedly connected to the side of the pin receiving slide rail 5251, and a locking spring 5254 is fixedly provided between the limiting plate 5253 and the pin receiving movable block 5252. The limiting plate 5253 serves two purposes: firstly, it limits the pin receiving movable block 5252 to prevent it from slipping; secondly, it also serves as a force-bearing support plate for the locking spring 5254. The locking spring 5254 is a compression spring. In this embodiment, a pin-receiving slide rail 5251 is also fixedly connected to a pin-receiving fixed block 5255, which is disposed opposite to the pin-receiving movable block 5252. Both the pin-receiving movable block 5252 and the pin-receiving fixed block 5255 have pin-receiving grooves 5256 on their opposite surfaces, which are adapted to the wire clamp pin 33. The cross-section of the pin-receiving groove 5256 is triangular, accommodating pins of different diameters. The space between the two pin-receiving grooves 5256 constitutes the receiving space for the wire clamp pin 33. Below the receiving space is a pin-blocking plate 5258 fixed on the module frame 522. The pin-blocking plate 5258 is used to prevent the wire clamp pin 33 from falling further, ensuring that the wire clamp pin 33 is located within the receiving space. A push rod 5250 is fixedly installed in the sliding cavity of the pin receiving slide rail 5251 to widen the receiving space. The dovetail slide groove mentioned in this embodiment refers to this sliding cavity. One end of the push rod 5250 is used to limit the position of the pin receiving movable block 5252 by abutting, and the other end is used to fix the position. When the pin receiving device 525 is located below the pin conveying cylinder 524, the receiving space is widened to receive the wire clamp pin 33 falling from the pin conveying cylinder 524. Specifically, after the pin receiving device 525 delivers the previous wire clamp pin 33, it returns to the bottom of the pin conveying cylinder 524 to wait for the next wire clamp pin 33. When not squeezed by the push rod 5250, the pin receiving movable block 5252 maintains a relatively close distance with the pin receiving fixed block 5255 under the action of the pin spring 5254. If there is a wire clamp pin 33 in the receiving space at this time, the wire clamp pin 33 is in a clamped state. The pin receiving device 525 gradually moves toward the pin conveying cylinder 524. When the dovetail slider of the pin receiving movable block 5252 touches the push rod 5250, the pin receiving movable block 5252 will be forced to stop moving because the position of the push rod 5250 is fixed. The pin receiving device 525 continues to move forward, causing the pin receiving movable block 5252 to be displaced relative to the limit plate 5253. At this time, the tight pin spring 5254 is in a compressed state, and the receiving space is also in a widened state.

[0040] In this embodiment, the operation of the pin receiving device 525 is as follows: the wire clamp pin 33 passes through the pin conveying cylinder 524 and continues to fall into the receiving space. Since a blocking plate 5258 is provided below the receiving space, the wire clamp pin 33 will be retained in the receiving space. The pin receiving device 525 moves linearly towards the plugging pin assembly 526. During the movement, the pin receiving movable block 5252 disengages from the top rod 5250, and the locking pin spring 5254 pushes the pin receiving movable block 5252 towards the pin receiving fixed block 5255, thus clamping the wire clamp pin 33 in the receiving space and keeping it in a vertical position.

[0041] Furthermore, in this embodiment, one end of the top rod 5250 is a free end, and the other end is fixedly connected to the module frame 522 via the module frame connecting plate 5271. A stop pin mounting bracket 5272 is also fixedly mounted on the module frame connecting plate 5271, and the stop pin plate 5258 is fixedly connected to the stop pin mounting bracket 5272 via a stop pin transition block 5259. The stop pin plate 5258 and the stop pin transition block 5259 are an integrated structure design, and the stop pin transition block 5259 is fixed to the stop pin mounting bracket 5272 by screws or other fasteners. A buffer spring 5273 is provided between the stop pin transition block 5259 and the module frame connecting plate 5271, and is sleeved on the stop pin mounting bracket 5272. Since the pin connector 525 will impact the stop pin transition block 5259 during reciprocating motion, the buffer spring 5273 is a compression spring, which can effectively absorb impact energy, thereby extending the service life of the stop pin transition block 5259 and the stop pin plate 5258.

[0042] In this embodiment, the rotary actuator 5231 is a rotary cylinder. An arc-shaped guide cover 5237 is provided at the discharge port of the sleeve 5234, surrounding the sleeve disc 5233. The arc-shaped guide cover 5237 is fixed to the housing of the rotary actuator 5231. The arc-shaped guide cover 5237 has a dual function: firstly, it prevents the wire clamp pin 33 from over-discharging into the sleeve 5234; secondly, it guides the wire clamp pin 33 during the rotation of the rotary actuator 5231, ensuring that the wire clamp pin 33 accurately enters the pin conveying cylinder 524, effectively avoiding slippage or positioning deviation during rotation.

[0043] In this embodiment, the feeding mechanism 51 includes a vibratory plate 511; the outlet of the vibratory plate 511 is connected to the inlet of the sleeve 5234 via a linear track 512 arranged in an inclined direction.

[0044] In this embodiment, the pin receiving slide rail 5251 is fixedly connected to the pin feeding slider 5211 of the linear drive assembly 521 via the stabilizing plate 5274. Both ends of the stabilizing plate 5274 are slidably connected to the stabilizing slide rail 5276 fixed on the module frame 522 via the stabilizing slider 5275. The structural design of the stabilizing plate 5274, stabilizing slider 5275, and stabilizing slide rail 5276 makes the operation of the wire clamp pin 33 more stable and the feeding of the wire clamp pin 33 more accurate, providing a strong foundation for subsequent pin positioning.

[0045] In this embodiment, the plugging pin assembly 526 includes a plugging pin ejector pin 5262 fixedly mounted on the piston rod of the plugging pin cylinder 5261, and an ejector pin guide platform 5263 that guides the plugging pin ejector pin 5262. The plugging pin assembly 526 is fixed on the module frame 522 by a bracket. With the guidance and assistance of the ejector pin guide platform 5263, the plugging pin ejector pin 5262 can maintain a precise coaxial relationship with the wire clamp pin 33 in the receiving space. When the plugging pin cylinder 5261 is activated, the plugging pin ejector pin 5262 is precisely pressed down axially, accurately inserting the wire clamp pin 33 into the pin hole (of course, the pin hole must be coaxial).

[0046] This embodiment of the pin-plugging device simplifies the mechanical structure and optimizes the operation process, significantly reducing the complexity of the pin-plugging process, improving equipment operational stability and operational flexibility. Furthermore, its high-precision, stable operation makes a significant contribution to completely abandoning the traditional probabilistic assembly method that relies on vibration assistance, ensuring the entire pin-plugging action is entirely deterministic and meets the requirements of modern intelligent manufacturing for process controllability. With its stable and reliable performance, excellent assembly quality, and high production efficiency, this embodiment not only significantly reduces the manufacturing cost of spacer bar clamps and enhances their market competitiveness but also opens up broad market application prospects for the pin-plugging device itself.

[0047] In summary, this is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent variations and modifications made in accordance with the shape, structure, features and spirit of the claims of the present utility model should be included within the scope of the claims of the present utility model.
