Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an insulator product crimping machine. Background Technology

[0002] Composite insulators are key components in high-voltage overhead transmission lines and substations, and their performance and reliability are directly related to the safe and stable operation of the entire power system. A typical composite insulator usually consists of a core rod, insulating skirts, and fittings. The core rod and fittings are generally fixedly connected by a crimping process, that is, the fittings are firmly crimped onto the core rod using a crimping machine.

[0003] Currently, there are double-ended composite insulator products on the market, with fittings installed at both ends of the core rod. During production, both ends of these products require crimping. However, traditional crimping equipment typically only allows for single-end crimping. This requires operators to crimp one end, remove the insulator from the clamp, reverse it, re-clamp it, and then crimp the other end. This production process has the following drawbacks: 1) It requires repeated clamping, increasing manual labor and leading to low production efficiency; 2) The positioning accuracy of the secondary clamping is difficult to guarantee, easily affecting the final assembly accuracy of the product.

[0004] To address the aforementioned issues, this application proposes a novel insulator crimping machine. Using this crimping machine, the crimping operation of double-ended composite insulators can be performed with a single clamping operation. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide an insulator product crimping machine that can crimp the fittings at both ends of the insulator product with only one clamping, thereby improving processing efficiency.

[0014] Furthermore, the vertical lead screw assembly also includes a follower block and a spring.

[0027] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. Example

[0028] like Figure 1-7 As shown, this embodiment is an insulator product crimping machine, including a frame 1. A crimping module 3 and a tooling fixture are provided on the frame 1. The crimping module 3 is located in the middle of the frame 1 and is used to crimp the fittings at the ends of the insulator. The tooling fixture includes two support seats 2, which are respectively installed on both sides of the crimping module 3. The crimping module 3 includes a crimping base 31. The crimping base is provided with a working through hole 32. A pressure block 34 and a driving member 33 are provided around the working through hole 32. The driving member 33 is used to push the pressure block 34 to crimp the fittings.

[0029] In this embodiment, a sliding groove is provided in the crimping seat 31, which is arranged radially along the working through hole 32. The pressing block 34 and the driving member 33 are disposed in the sliding groove. Under the action of the driving member 33, the pressing block 34 moves towards the center of the working through hole 32. The diameter of the working through hole 32 is larger than the maximum diameter of the insulator product 5 to be processed, so that the entire insulator product 5 to be processed can pass freely through the working through hole 32.

[0030] In this embodiment, the support base 2 includes a base plate 21, on which a horizontal moving mechanism is provided, and on which a vertical moving mechanism 25 is provided; the horizontal moving mechanism includes a horizontal slide rail 22, a horizontal slider 23, and a horizontal sliding seat 24; the horizontal slider 23 is slidably mounted on the horizontal slide rail 22; the horizontal sliding seat 24 is fixed on the horizontal slider 23; the vertical moving mechanism 25 includes a vertical slide rail 251, a vertical slider 252, and a vertical sliding seat 250; the vertical slide rail 251 is fixed on the horizontal sliding seat 24, the vertical slider 252 is slidably mounted on the vertical slide rail 251, and the vertical sliding seat 250 is fixed on the vertical slider 252; a fixing block 26 is provided on the vertical sliding seat 250; the fixing block 26 is used to cooperate and fix with both ends of the insulator product 5.

[0031] In this embodiment, the vertical moving mechanism 25 includes a vertical lead screw assembly for adjusting the position of the vertical sliding seat 250 on the vertical slide rail 251. The vertical lead screw assembly includes a fixed base 253, a vertical lead screw 254, a guide shaft 256, a moving block 255, and a handle 259. The two ends of the vertical lead screw 254 are rotatably mounted on a horizontal sliding seat 24 via the fixed base 253. Two guide shafts 256 are respectively located on both sides of the vertical lead screw 254 and are arranged parallel to it. The moving block 255 has through holes for engaging with both the vertical lead screw 254 and the guide shafts 256, allowing the moving block 255 to simultaneously fit onto both the vertical lead screw 254 and the guide shafts 256. A threaded structure is provided on the moving block 255 at the through hole corresponding to the vertical lead screw 254. One end of the vertical lead screw 254 is connected to the handle 259; rotating the handle 259 will cause the vertical lead screw 254 to rotate, thereby driving the moving block 255 to move up and down.

[0032] In this embodiment, the vertical lead screw assembly further includes a follower block 257 and a spring 258. The follower block 257 is positioned above the moving block 255 and has a through hole that mates with the vertical screw 254 and the guide shaft 256, allowing the follower block 257 to be simultaneously fitted onto both the vertical screw 254 and the guide shaft 256, with the follower block 257 positioned above the moving block 255. The spring 258 is fitted onto the guide shaft 256 between the moving block 255 and the follower block 257. The follower block 257 is fixedly connected to the vertical sliding seat 250. When the moving block 255 moves, it exerts a force on the spring 258, indirectly driving the follower block 257 to move. A locking hole is provided on the side wall of the fixed seat 253, corresponding to the position of the vertical screw 254. A wing bolt is provided in the locking hole; after the wing bolt is tightened, the vertical screw 254 is locked and cannot rotate. The vertical screw assembly employs a structure of moving block 255, follower block 257, and spring 258, which enables the insulator product 5 to be elastically fixed in the vertical direction. This facilitates the automatic adaptation of the product in the vertical direction during the crimping process and improves the fault tolerance rate.

[0033] In this embodiment, the horizontal moving mechanism of the bracket 2 also includes a locking mechanism, which is also a wing bolt. The wing bolt is installed in the threaded through hole on the horizontal sliding seat 24. When the wing bolt is tightened, the horizontal sliding seat 24 is fixed in place.

[0034] In this embodiment, the fixing block 26 is provided with a limiting structure 261 for matching the end of the insulator product 5; the limiting structure 261 is a groove.

[0035] In this embodiment, the tooling fixture also includes a synchronizing rod 4, the two ends of which are detachably connected to the horizontal sliding seats 24 of the two support seats 2, respectively, to keep the two horizontal sliding seats 24 moving synchronously. A connecting rod through hole 35 is provided on the crimping seat for the synchronizing rod 4 to pass through. The length of the synchronizing rod 4 corresponds to the length of the product to be processed. Of course, in other specific embodiments, the synchronizing rod 4 can also be a telescopic rod structure with a length locking function, ensuring that the horizontal sliders 23 maintain different distances, thus making it suitable for processing insulator products 5 of different lengths.

[0036] In this embodiment, the method of using the insulator product 5 crimping machine is as follows: insert both ends of the insulator product 5 to be processed into the corresponding two fixed blocks 26, and adjust the relative distance of the horizontal sliding seats 24. Use the synchronous connecting rod 4 of the corresponding length to connect the two horizontal sliding seats 24. At this time, the insulator product 5 can be fixed on the tooling fixture. Only one horizontal sliding seat 24 needs to be pushed, and the other will move synchronously. Push any one horizontal sliding seat 24 so that one end of the insulator product 5 is located in the working area of ​​the crimping module 3 and crimped. After crimping, push any one horizontal sliding seat 24 again so that the other end of the insulator product 5 is located in the working area of ​​the crimping module 3 and crimped. This completes the crimping work at both ends. During the operation, there is no need to clamp the insulator product 5 twice, which improves the work efficiency and can improve the consistency of the insulator product 5 after each processing (such as ensuring that the length of the product is consistent).

[0037] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
