Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding and fixing technology, and in particular relates to a welding and fixing device and its welding fixture. Background Technology
[0002] A ring main unit (RMU) is a type of high-voltage switchgear installed within an insulated cabinet. To ensure safe operation, the RMU requires strict airtightness of the insulated cabinet. The insulated cabinet is constructed by welding together multiple panels, and the fitting precision between adjacent panels is critical.
[0003] Currently, workers hold the ring main unit panels and place them onto a welding fixture. The fixture then secures the panels before welding adjacent panels. However, due to the low precision of the workers' panel feeding, the welding fixture can only provide initial positioning, resulting in poor panel fit. To ensure the airtightness of the insulation cabinet, workers need to repeatedly load and unload the panels until they are aligned. This time-consuming panel loading and unloading leads to a long welding time for the ring main unit and low welding efficiency. Utility Model Content
[0004] This utility model provides a welding fixing device and its welding fixture, which can finely adjust the position of the vertical panel during the plate feeding process, thereby improving welding efficiency while ensuring the fitting accuracy of the vertical panel.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0016] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. Terms such as "first," "objective," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0017] This utility model provides a welding fixing device and its welding fixture. The welding fixing device includes: a vertical frame; at least one first suction cup assembly, which is installed on one side of the vertical frame and includes at least one first suction cup; at least one second suction cup, which is fixed to the vertical frame, and the first and second suction cups are oriented in the same direction; a first triggering device, a first cylinder, and a second cylinder, wherein the first triggering device is flush with the first suction cup and electrically connected to the first cylinder, the first cylinder is connected to all the first suction cups, the second cylinder is connected to all the second suction cups, and the number of second suction cups is greater than the number of first suction cups. According to the technical solution of this embodiment, since the number of first suction cups is less than the number of second suction cups, the panel attached to the first suction cup can remain vertical and its position can be adjusted. After adjusting the position of the panel until it is in the preset position, all the second suction cups are attached to the panel, thereby fixing the panel by the first and second suction cups. The panel can be finely adjusted before it is completely fixed, thus ensuring the matching accuracy between the panels. The position of the panel can be adjusted without repeated loading and unloading, thereby reducing the required loading and unloading time and improving the welding efficiency of the ring main unit.
[0018] Reference Figure 1 and Figure 2 The welding fixing device provided in this embodiment includes: Vertical frame 10; At least one first suction cup assembly 20 is mounted on one side of the vertical frame 10, and the first suction cup assembly 20 includes at least one first suction cup 21; At least one second suction cup 30 is fixed to the vertical frame 10, and the first suction cup 21 and the second suction cup 30 are in the same direction; The first triggering device 61, the first cylinder, and the second cylinder are all connected. The first triggering device is flush with the first suction cup 21. The first triggering device 61 is electrically connected to the first cylinder. The first cylinder is connected to all the first suction cups 21. The second cylinder is connected to all the second suction cups 30. The number of second suction cups 30 is greater than the number of first suction cups 21.
[0019] It should be noted that the vertical frame 10 includes multiple horizontal bars and multiple vertical bars, and the vertical panel is fixed to the front side of the vertical frame 10 by the first suction cup 21 and the second suction cup 30.
[0020] It should be noted that when the plate is fed into the welding fixing device, the vertical panel abuts against the first suction cup 21, forming a sealed space between the vertical panel and the first suction cup 21. The first cylinder evacuates all the first suction cups 21, causing them to adhere to the vertical panel, thus achieving initial fixation of the vertical panel. After the initial fixation and position adjustment of the vertical panel are completed, the second cylinder is activated, evacuating all the second suction cups 30. All the second suction cups 30 adhere to the vertical panel, and together all the first and second suction cups complete the final fixation of the vertical panel.
[0021] It should be noted that when the volume of the vertical panel increases, the number of the first suction cup assembly 20 is increased accordingly, and the first suction cups 21 are distributed at the edge of the vertical panel.
[0022] It should be noted that when the distance between the vertical panel and the welding fixing device reaches the preset threshold, the third cylinder drives the first panel 22 to move closer to the vertical panel. When the first suction cup 21 abuts against the vertical panel, the first triggering device 61 abuts against the vertical panel. The first triggering device 61 sends an electrical signal to the first cylinder, and the first cylinder draws a vacuum to the first suction cup 21, so that all the first suction cups 21 are attracted to the vertical panel.
[0023] It should be noted that when the plate is fed to the welding fixing device, and the vertical panel abuts against the first triggering device 61, the first suction cup 21, and the second suction cup 30, the first triggering device 61 sends an electrical signal to the first cylinder, which starts the first cylinder. The first cylinder evacuates the sealed space between all the first suction cups 21 and the vertical panel, so that all the first suction cups 21 are attracted to the vertical panel. After all the first suction cups 21 are attracted to the vertical panel, the position of the vertical panel is adjusted until the vertical panel is in the preset position. After the position of the vertical panel is adjusted, the second cylinder is started, which evacuates the sealed space between the second suction cup 30 and the vertical panel, so that all the second suction cups 30 are attracted to the vertical panel. At this time, all the first suction cups 21 and all the second suction cups 30 are attracted to the vertical panel, thereby fixing the vertical panel.
[0024] It should be noted that because the number of first suction cups 21 is small, the suction force of all first suction cups 21 on the vertical panel is small. This allows for fine-tuning of the vertical panel while it remains in a vertical position. After fine-tuning, all second suction cups 30 are used to hold the vertical panel in place, thus fixing the vertical panel in place. Fine-tuning can be performed before the vertical panel is fully fixed, ensuring a good fit between the panels and eliminating the need for repeated disassembly and adjustment of the panel's position, thereby improving welding efficiency.
[0025] Additionally, a welding fixing device is used to fix a vertical panel, which includes at least one through hole. In one embodiment, refer to... Figure 1and Figure 2 It also includes: At least one core-pulling shaft assembly, the core-pulling shaft assembly includes a core-pulling shaft 41 and a first motor 42, the first motor 42 is fixed to the vertical frame 10, the output shaft of the first motor 42 is fixed to the rear end of the core-pulling shaft 41, the first motor 42 is used to drive the core-pulling shaft 41 to move horizontally along the Y-axis direction, the core-pulling shaft 41 can pass through the through hole, and the number of core-pulling shafts 41 is less than or equal to the number of through holes.
[0026] It should be noted that when the vertical panel is adjusted to a preset position, the core-pulling shaft 41 can pass through the through hole of the vertical panel. During the adjustment of the vertical panel, the first motor 42 is started to drive the core-pulling shaft 41 to move horizontally, thereby providing an adjustment reference for the preset position of the vertical panel.
[0027] It should be noted that when the core-pulling shaft 41 is inserted into the through hole, the core-pulling shaft 41 can provide vertical support force for the vertical panel.
[0028] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 The vertical frame 10 includes multiple movable rods 11, which are arranged along the X-axis. A first suction cup assembly 20 is mounted on the movable rod 11 and can move horizontally on the movable rod 11.
[0029] It should be noted that, in order to make the welding fixing device applicable to fixing vertical panels of more sizes to be welded, when the first suction cup 21 is connected to the through hole of the vertical panel, the first suction cup assembly 20 can be moved to the moving rod 11 by manual or driving equipment, thereby adjusting the position of the first suction cup 21 so that the first suction cup 21 can be attracted to the vertical panel, thereby expanding the application range of the welding fixing device.
[0030] It should be noted that by adding the moving rod 11, the directional stability of the first suction cup assembly when moving along the X-axis is determined. Based on the area of the vertical panel, the number of moving rods is adaptively adjusted to prevent the first suction cup assembly from shaking or shifting during horizontal movement along the X-axis, which would prevent the first suction cup from forming a sealed space with the vertical panel to complete the suction.
[0031] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 The first suction cup assembly 20 also includes a first panel 22 and a third cylinder 23. The first panel 22 and the third cylinder 23 are both mounted on the vertical frame 10. The first panel 22 is parallel to the vertical frame 10. All the first suction cups 21 are fixed to the front side of the first panel 22. The output end of the third cylinder 23 is fixed to the rear side of the first panel 22. The third cylinder 23 is used to drive the first panel 22 to move along the Y-axis.
[0032] It should be noted that all the first suction cups 21 are fixed to the front side of the first panel 22, which facilitates the movement of all the first suction cups 21 in the horizontal direction and reduces the number of driving devices required.
[0033] It should be noted that during the board feeding process, when there is a certain distance between the first suction cup 21 and the vertical panel, the vertical panel is kept stationary, and the third cylinder 23 is activated. The third cylinder 23 drives the first panel 22 to move along the Y-axis towards the vertical panel, thereby driving all the first suction cups 21 to approach the vertical panel until all the first suction cups 21 are attracted to the vertical panel. Then, the third cylinder 23 drives the first panel 22 to move along the Y-axis towards the vertical frame 10, so that the second suction cup 30 can abut against the vertical panel. When the second suction cup 30 abuts against the vertical panel, the second cylinder is activated to achieve the attraction of all the second suction cups 30 to the vertical panel. Finally, all the first suction cups 21 and all the second suction cups 30 are attracted to the vertical panel together, completing the fixation of the vertical panel by the welding fixing device.
[0034] It should be noted that the third cylinder 23 can prevent the vertical panel from colliding with the welding fixing device and provide adjustment space for the position adjustment of the vertical panel.
[0035] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 It also includes: The second motor 50 has its output shaft connected to the rear side of the entire first panel 22. The second motor 50 is used to drive the first panel 22 to move along the moving rod 11.
[0036] It should be noted that when all the through holes provided on the vertical panel coincide with at least one first suction cup 21, the first suction cup 21 that coincides with the vertical panel cannot form a sealed space with the panel and thus cannot be attracted to the vertical panel. This results in a reduction in the suction force of the first suction cup assembly 20 on the vertical panel, and the vertical panel cannot maintain its vertical state.
[0037] It should be noted that when all the through holes of the vertical panel coincide with at least one first suction cup 21, the second motor 50 drives all the first suction cups 21 installed on the front side of the first panel 22 to move along the X-axis until all the first suction cups 21 and the vertical panel can form a sealed space, thereby ensuring that the suction force of the first suction cup assembly 20 on the vertical panel meets the requirements.
[0038] Additionally, in one embodiment, reference is made to Figure 1 and Figure 2 It also includes: The second triggering device 62 is installed on the front side of the vertical frame 10 and is electrically connected to the second cylinder.
[0039] It should be noted that, in order to improve the automation level of the welding fixing device, a second triggering device 62 is provided on the front side of the vertical frame 10. After all the first suction cup assemblies 20 are attracted to the vertical panel, the third cylinder 23 drives the first panel 22 to retract. When the vertical panel abuts against the second triggering device 62, the second triggering device 62 sends an electrical signal to the second cylinder, which in turn causes all the second suction cups 30 to be attracted to the vertical panel, thereby achieving the attraction of all the first suction cups 21 and all the second suction cups 30 to the vertical panel, and the welding fixing device fixes the vertical panel.
[0040] It should be noted that when at least one first suction cup 21 coincides with the through hole of the vertical panel, the second motor 50 is activated, driving the first suction cup 21 to move horizontally until all the first suction cups 21 are attracted to the vertical panel. The vertical panel is then brought close to the welding fixing device. When the distance between the vertical panel and the welding fixing device is less than a preset threshold, the third cylinder 23 is activated. The third cylinder 23 drives the first panel 22 to move along the X-axis towards the vertical panel, bringing the first suction cups 21 closer to the vertical panel. When the first suction cups 21 and the first triggering device 61 abut against the vertical panel, the first triggering device 61 sends an electrical signal to the first cylinder, activating the first cylinder. The first cylinder then evacuates the sealed space between all the first suction cups 21 and the vertical panel, causing all the first suction cups 21 to be attracted to the vertical panel. Once all the first suction cups 21 are attracted to the vertical panel, the position of the vertical panel is adjusted. After adjustment, the first panel 22 is moved along the X-axis towards the vertical frame 10 by the second motor 50, so that the vertical panel is close to the vertical frame 10. When the vertical panel abuts against the second trigger device 62, the second trigger device 62 sends an electrical signal to the second cylinder, and the second cylinder draws a vacuum in the sealed space between the second suction cup 30 and the vertical panel, so that all the second suction cups 30 are attracted to the vertical panel. The first motor 42 is started, and the first motor 42 drives the core-pulling shaft 41 to move along the X-axis towards the vertical panel. The core-pulling shaft 41 passes through the through hole of the vertical panel. At this time, the welding fixing device fixes the vertical panel. The welding and fixing device of this application uses a core-pulling shaft 41 to position the vertical panel, a second motor 50 to perform horizontal displacement of the first suction cup assembly 20 to reduce manual labor, and a third cylinder 23 to prevent the vertical panel from colliding with the welding and fixing device due to excessive speed during plate feeding. A small number of first suction cups 21 provide initial fixing to the vertical panel, keeping it vertical and allowing for fine-tuning. After the vertical panel is adjusted, all first suction cups 21 and all second suction cups 30 adhere to the vertical panel to achieve fixation. This welding and fixing device reduces the number of times the vertical panel needs to be assembled and disassembled, thereby reducing welding time while maintaining the alignment accuracy between the vertical panel and other panels, thus improving welding efficiency.
[0041] In addition, this utility model embodiment also provides a welding fixture, including the welding fixing device as described above.
[0042] It should be noted that the welding fixture can be the welding fixing device itself or other equipment that uses welding fixing devices. This embodiment does not limit the specific type of welding fixture, as long as the above-mentioned welding fixing device can be used.
[0043] Additionally, in one embodiment, reference is made to Figure 2 It also includes: The guide rail 71 and at least one slide plate 72 are provided. The guide rail 71 is parallel to the X-axis, and the slide plate 72 can slide on the guide rail 71. The welding fixture is fixed to the upper surface of the slide plate 72. When there are two welding fixtures, the two vertical frames 10 are parallel to each other, and the first suction cups 21 of the two welding fixtures are in opposite directions.
[0044] It should be noted that the ring main unit includes two vertical panels and one horizontal vertical panel. In the actual production of the ring main unit, the two vertical panels are vertically welded to the two ends of the horizontal vertical panel respectively. The welding fixture is fixed to the slide plate 72, and the slide plate 72 can slide on the guide rail 71, so that the welding fixture can be applied to horizontal panels of different sizes, thereby enhancing the practicality of the welding fixture.
[0045] It should be noted that when there are two welding fixing devices, the welding fixture includes at least two slides, one welding fixing device is fixed to the upper surface of one slide, and the slide 72 is driven to move horizontally on the guide rail 71, thereby realizing the horizontal movement of the welding fixing device along the X-axis direction; by adjusting the distance between the two welding fixing devices, it can be applied to horizontal panels of different sizes.
