Description

Technical Field

[0001] The invention relates to the technical field of welding fixing tooling, in particular to a fixing tooling and a method for copper soft connection welding. Background Art

[0002] Copper soft connectors are suitable for various high-voltage electrical appliances, vacuum electrical appliances, explosion-proof switches for mining, automobiles, locomotives and other related products. The interface of the copper soft connector is formed by one-time welding using molecular diffusion welding technology. The product has good quality, strong conductivity, large current bearing, small resistance value, and durability. It is widely used in metallurgy, chemical industry, power transmission and transformation engineering and power equipment. At present, the welding process of copper soft connectors usually adopts molecular diffusion welding. When welding, multiple pieces of copper need to be inserted between the upper and lower graphite electrodes. After the equipment is pressed, a large current is passed to heat the graphite, so that the copper sheet is at a certain temperature and a certain pressure. The molecules between the contact surfaces are diffused by high temperature to form a joint. At this time, fixed tooling is needed to assist the stable welding operation.

[0003] When performing soft connection welding on multiple layers of copper sheets, due to the large difference in heat exposure of each layer of copper sheets, it is easy for the welding strength between the copper soft connectors in the middle to be poor or even impossible to weld together.

[0034] See also Figure 1-Figure 9 , a method for using a copper soft connection welding fixture shown in the figure includes the following steps:

[0035] S1. The copper sheet 36 to be welded is placed in the first conveyor frame 3 and the second conveyor frame 4 for storage, and the copper sheet 36 required for welding in the initial state is clamped and fixed by a fixing mechanism;

[0040] Embodiment 2

[0041] See also Figure 1-Figure 9 The present embodiment further illustrates the first embodiment. The conveying mechanism shown in the figure includes a first electric telescopic rod 13 fixedly mounted on the base 1. The telescopic end of the first electric telescopic rod 13 is fixedly connected to a device box 14. A device groove 15 is provided in the device box 14. Two groups of push plates 7 are provided, and both are slidably connected to the inner wall of the device groove 15 along the vertical direction. The first gear rod 11 is provided with an adjusting member 16 for synchronously adjusting the positions of the second gear rod 12 and the push plate 7 when adjusting the height of the first gear rod 11.

[0042] The adjusting member 16 includes a threaded rod 17 rotatably connected to the top of the first gear rod 11 through a rotating buckle, the threaded rod 17 passes through the side of the first conveying frame 3, and is threadedly connected to the first conveying frame 3, the sides of the first gear rod 11 and the second gear rod 12 are respectively fixedly connected with a sliding frame 18, and a guide rod 19 is fixedly connected to the sliding frame 18. The two groups of push plates 7 are respectively provided with guide grooves 20 that are slidably connected to the upper and lower groups of guide rods 19 in the horizontal direction. A control member 21 for controlling the two groups of push plates 7 to perform synchronous reverse lifting and sliding is provided in the device box 14.

[0043] The control member 21 includes two groups of mounting rods 22 installed in the device box 14. A sliding groove 23 is opened in the device box 14. The mounting rod 22 is slidably connected to the sliding groove 23 along the horizontal direction. One end of the mounting rod 22 is rotatably connected to two groups of connecting rods 24 that are respectively rotatably connected to the two groups of push plates 7. The end of the mounting rod 22 away from the connecting rod 24 is fixedly connected to a second spring 25 fixedly connected to the sliding groove 23.

[0044] The conveying mechanism also includes a second electric telescopic rod 26 fixedly mounted on the support plate 2, the telescopic end of the second electric telescopic rod 26 is fixedly connected to the top surface of the first pallet 5, the first pallet 5 and the second pallet 6 are respectively connected to the support plate 2 in a vertical sliding direction, and the second gear rod 12 is provided with a driving member 27 for synchronously adjusting the height of the second pallet 6 without affecting the lifting and clamping of the second pallet 6.

[0045] The driving member 27 includes a third spring 28 fixedly mounted on the bottom of the second support plate 6. The second support plate 6 is slidably connected to the side of the second gear rod 12 in the vertical direction. The bottom end of the third spring 28 is fixedly connected to the second gear rod 12. A third electric telescopic rod 29 for lifting the second support plate 6 is fixedly connected to the support plate 2. The top end of the third electric telescopic rod 29 is located below the two ends of the second support plate 6.

[0046] In this embodiment, rotating the threaded rod 17 drives the first gear rod 11 to rise and fall, and the first gear rod 11 drives the upper sliding frame 18 to rise and fall, thereby driving the guide rod 19 to make the upper push plate 7 rise and fall. During the lifting process, the upper push plate 7 drives the connecting rod 24 to rotate, thereby driving the mounting rod 22 to slide horizontally in the sliding groove 23. Since the connecting rods 24 on the upper and lower sides are the same length, the lower push plate 7 will be adjusted in the opposite direction to the upper push plate 7, changing the number of copper sheets 36 that can be pushed during each sliding process. At the same time, the second gear rod 12 is driven to adjust to the corresponding position through the lower sliding frame 18, and the local position of the output port 10 is blocked by the first gear rod 11 and the second gear rod 12, so that the required number of copper sheets 36 can be pushed out from the output port 10 to the upper side of the first support plate 5 and the second support plate 6 each time.

[0047] The position of the first pallet 5 is driven by the second electric telescopic rod 26, so that the top surface of the first pallet 5 is always flush with the bottom end position of the upper output port 10, ensuring that the copper sheet 36 in the first conveying frame 3 can be directly pushed out to the first pallet 5 through the output port 10, and the position of the second pallet 6 is affected by the position of the second gear rod 12, and the position of the second pallet 6 can be synchronously adjusted during the lifting and lowering of the second gear rod 12, so that the top surface of the second pallet 6 is flush with the top surface of the second gear rod 12 and is adjusted synchronously. When the first electric telescopic rod 13 pushes the device box 14 so that the pushing plates 7 on the upper and lower sides push the copper sheets 36 in the first conveying frame 3 and the second conveying frame 4 to the output port 10, the copper sheet 36 at the bottom just falls on the upper side of the second pallet 6.

[0048] The welded part of the copper flexible connection is moved between the first support plate 5 and the second support plate 6 by the fixing mechanism, and the second electric telescopic rod 26 is started to push the first support plate 5 downward to clamp the top of the copper flexible connection, and the second support plate 6 is pushed upward by the third electric telescopic rod 29, and the third spring 28 is stretched, and the position of the second gear lever 12 remains unchanged. The second support plate 6 pushes the upper copper sheet 36 upward to contact and clamp the bottom of the copper flexible connection, and the fixing mechanism can be withdrawn, and the copper sheet 36 on the first support plate 5 and the second support plate 6 is clamped as a whole again and transported to the required position for subsequent secondary welding operations. In this way, in the process of welding the copper flexible connection, welding and fixing are gradually carried out from the middle to the two sides, thereby improving the stability of welding in the middle position. Since the upper and lower sides are clamped and heated synchronously during the welding process, the welding efficiency of synchronous feeding and welding on the upper and lower sides is higher than that of single-side layer-by-layer feeding.

[0049] Embodiment 3

[0050] See also Figure 1-Figure 4 The present embodiment further illustrates the first embodiment. The fixing mechanism shown in the figure also includes a mounting frame 30 fixedly mounted on the base 1. Two groups of first hydraulic rods 31 are fixedly connected to the mounting frame 30. The telescopic ends of the first hydraulic rods 31 are fixedly connected to a guide frame 32. A clamping plate 33 is slidably connected in the horizontal direction in the guide frame 32. A second hydraulic rod 34 is fixedly connected in the guide frame 32. The telescopic ends of the second hydraulic rods 34 are fixedly connected to the side surfaces of the clamping plates 33. The clamping plates 33 are rotatably connected to multiple groups of driving rollers 35 that can drive copper sheets 36 for horizontal conveying adjustment.

[0051] In this embodiment, the extension and retraction of the first hydraulic rod 31 is controlled to drive the guide frame 32 and the clamping plate 33 to rise and fall, open and close, and the extension and retraction of the second hydraulic rod 34 is controlled to drive the clamping plate 33 to move horizontally, so that the copper flexible connector can be moved to the desired position for loading and welding operations. The welding equipment is arranged in the area between the mounting frame 30 and the support plate 2. In the early stage of welding, the number of copper sheets 36 for the first welding needs to be pre-installed according to the required number of layers of copper sheets 36 and the number of layers of copper sheets 36 required for each welding. Since the number of copper sheets 36 loaded each time is a symmetrical even number, if the total number of copper sheets 36 is an odd number, the number of copper sheets 36 clamped between the clamping plates 33 during the initial welding needs to be an odd number. Otherwise, the even number of copper sheets 36 is fixed for welding.

[0052] It is worth noting that: during the welding process, the copper flexible connector can be driven to adjust the clamping position by the rotation of the driving roller 35, so that each position of the copper flexible connector can be clamped and welded by the welding equipment. After the welding is completed, the copper flexible connector needs to be moved to the middle position of the clamping plate 33 and pushed between the first support plate 5 and the second support plate 6 for loading operation. The position of the clamping plate 33 does not overlap with the position of the first support plate 5 and the second support plate 6 in the vertical direction, so as to prevent the clamping plate 33 from being directly clamped and fixed during the clamping process of the first support plate 5 and the second support plate 6. The first support plate 5 adopts a structure of clamping under pressure on both sides, and the clamping The plate 33 is in the middle position, and in subsequent operations, the clamping plate 33 can be directly controlled to move to above the copper sheet 36 on the first support plate 5, and then the clamping plates 33 on both sides can be controlled to close and clamp. At this time, the clamping plate 33 at the bottom can pass through the second support plate 6 to directly clamp the copper sheet 36, while the clamping plate 33 on the upper side will press the copper sheet 36 together with the first support plate 5. Since the copper sheet 36 has a certain elasticity, the middle part can be recessed to a state of conflicting with the lower copper soft connection. After that, the clamping plate 33 drives the copper sheet 36 to move horizontally, and the copper sheet 36 can be directly pulled away from the first support plate 5 and the second support plate 6 to complete the loading.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
