Description

Technical Field

[0001] This utility model relates to the field of sheet metal joining technology, and in particular to a mobile sheet metal joining device suitable for on-site operations. Background Technology

[0002] In modern engineering construction and field operations, the application of sheet metal joining devices is becoming increasingly widespread, especially in industries such as construction, manufacturing, and transportation, where flexible and efficient equipment is often required for connecting sheet metal. Traditional sheet metal joining devices typically have fixed or semi-fixed structures. However, in field operations, due to the uncertainty of the operating environment and the differences in site conditions, these traditional devices are often unable to cope with complex terrain or the need for rapid movement and adjustment.

[0003] Currently, existing sheet metal joining devices generally employ simple mechanical structures, such as fixed supports, slide rails, and clamps, with the device's position and clamping force adjusted manually or electrically. Traditional devices often use fixed wheels or support frames to allow the equipment to move or adjust on flat ground. However, these devices are typically ineffective on uneven ground or in working environments requiring rapid and stable fixing. Furthermore, the stability of existing technologies relies primarily on the basic support frame and clamps, leading to instability or wobbling during actual operation, especially when precision docking or heavy handling is required, where insufficient stability becomes particularly pronounced.

[0004] However, existing sheet metal joining devices often encounter support swaying or instability during movement. Due to the lack of an effective self-locking or stabilizing mechanism, traditional equipment cannot maintain sufficient stability on complex ground or uneven terrain, leading to tilting or offset during sheet metal joining operations, thus affecting the accuracy and safety of the operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mobile plate joining device suitable for on-site operations, aiming to improve the swaying and instability problems that occur during the movement of the support in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile plate joining device suitable for on-site operation, comprising a support, a fixed frame fixedly connected to the top of the support, casters fixedly connected to the bottom of the support, and a grounding component provided inside the support;

[0007] The landing component includes a first support block, the bottom of which is fixedly connected to the inner wall of the bracket. A motor is fixedly connected inside the first support block. A first rotating plate is fixedly connected to the output end of the motor. A second rotating plate is rotatably connected to the side wall of the first rotating plate. A limit plate is fixedly connected to the side wall of the bracket. A sliding plate is slidably connected to the inner wall of the limit plate. An anti-slip plate is fixedly connected to the bottom of the sliding plate. The side wall of the second rotating plate is rotatably connected to the side wall of the sliding plate.

[0008] As a further description of the above technical solution:

[0009] A rotating shaft is fixedly connected to the top of the fixed frame, and a third rotating plate is rotatably connected inside the rotating shaft.

[0010] As a further description of the above technical solution:

[0011] The top of the fixed frame is fixedly connected to a slide rail, and a slider is slidably connected to the outer wall of the slide rail.

[0012] As a further description of the above technical solution:

[0013] A second support block is fixedly connected to the top of the fixed frame, and a connecting block is rotatably connected to the side wall of the second support block.

[0014] As a further description of the above technical solution:

[0015] A hydraulic cylinder is fixedly connected to the side wall of the connecting block, and a connecting frame is fixedly connected to the output end of the hydraulic cylinder.

[0016] As a further description of the above technical solution:

[0017] A movable plate is rotatably connected to the inner wall of the connecting frame. The bottom of the movable plate is fixedly connected to the top of the slider, and a clamping block is fixedly connected to the top of the movable plate.

[0018] As a further description of the above technical solution:

[0019] The top of the movable plate is rotatably connected to a linkage rod, and the side wall of the linkage rod is rotatably connected to the side wall of the third rotating plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the first rotating plate is driven to rotate by a motor. The first rotating plate drives the second rotating plate on the side wall to rotate. Then, the second rotating plate is subjected to force and drives the sliding plate to the inner wall of the limiting plate. Subsequently, the sliding plate is subjected to force and pushes the bottom anti-slip plate against the ground, thereby achieving the effect of fixing the position of the bracket. This solves the problem of shaking and instability of the bracket during movement and improves the stability of the plate joining device.

[0022] 2. In this utility model, the hydraulic cylinder drives the connecting frame to move the inner wall moving plate. Then the moving plate drives the linkage rod to rotate, and the linkage rod drives the third rotating plate to rotate together, bringing the two moving plates together. Finally, the moving plate drives the slider to limit the moving plate on the outer wall of the slide rail, achieving the effect of adaptive clamping of the plate. This solves the problem of loosening or misalignment of the plate during the clamping process and improves the accuracy of the plate joining device. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3The present invention provides an embodiment of a mobile plate joining device suitable for on-site operations, comprising a support 1, a fixed frame 4 fixedly connected to the top of the support 1, and casters 2 fixedly connected to the bottom of the support 1. The casters 2 are used to drive the support 1 and the entire device to move, thereby facilitating the quick transfer of the device to different on-site work locations by the staff, reducing the intensity of manual handling, and improving the efficiency of the work preparation stage. The support 1 is equipped with a grounding component.

[0032] The landing component includes a first support block 3, the bottom of which is fixedly connected to the inner wall of the bracket 1. A motor 5 is fixedly connected inside the first support block 3, and a first rotating plate 6 is fixedly connected to the output end of the motor 5. A second rotating plate 7 is rotatably connected to the side wall of the first rotating plate 6. A limit plate 8 is fixedly connected to the side wall of the bracket 1. The limit plate 8 cooperates with the sliding plate 9 to slide vertically, thereby constraining the movement direction of the sliding plate 9 and preventing it from shifting horizontally under the drive of the second rotating plate 7. This achieves the effect of ensuring that the anti-slip plate 10 can accurately and vertically contact the ground and stably support the device. The sliding plate 9 is slidably connected to the inner wall of the limit plate 8, and the anti-slip plate 10 is fixedly connected to the bottom of the sliding plate 9. The anti-slip plate 10 is used to increase the contact friction between the sliding plate 9 and the ground, thereby preventing the device from shaking due to the slippage of the universal wheel 2 or uneven ground during the plate joining operation, ensuring the overall stability of the device and providing a guarantee for accurate joining. The side wall of the second rotating plate 7 is rotatably connected to the side wall of the sliding plate 9.

[0033] Reference Figure 4 and Figure 5A rotating shaft 15 is fixedly connected to the top of the fixed frame 4. The rotating shaft 15 provides a rotational support point for the third rotating plate 14, thereby limiting the movement trajectory of the third rotating plate 14 and ensuring that it can rotate stably around the fixed axis. This provides a basis for the transmission of the linkage rod 13 and the synchronous approach of the two moving plates 11. The third rotating plate 14 is rotatably connected inside the rotating shaft 15. A slide rail 16 is fixedly connected to the top of the fixed frame 4. Both the slide rail 16 and the slider 21 are made of 45# steel. 45# steel has high strength and wear resistance and is used to achieve smooth sliding of the moving plate 11. This is common knowledge and will not be elaborated further here. The slider 21 is slidably connected to the outer wall of the slide rail 16. A second support block 17 is fixedly connected to the top of the fixed frame 4. A connecting block 18 is rotatably connected to the side wall of the second support block 17. A hydraulic cylinder 19 is fixedly connected to the side wall of the connecting block 18. The hydraulic cylinder 19 is a Rexroth CDH1 series and is used to provide linear thrust to push the connecting frame 20 and the moving plate 11 to move. The hydraulic cylinder 19 provides power for the clamping action of the sheet metal, which is existing technology and will not be described in detail here. The hydraulic cylinder 19 works with the connecting frame 20 to perform telescopic pushing motion. The connecting frame 20 drives the moving plate 11 to move along the slide rail 16. At the same time, the moving plate 11 on the other side is linked through the linkage rod 13 and the third rotating plate 14, so as to achieve the effect of applying clamping force from both sides simultaneously and avoiding the sheet metal from being deviated by force on one side. The output end of the hydraulic cylinder 19 is fixedly connected to the connecting frame 20. The moving plate 11 is rotatably connected to the inner wall of the connecting frame 20. The bottom of the moving plate 11 is fixedly connected to the top of the slider 21. The top of the moving plate 11 is fixedly connected to the clamping block 12. The clamping block 12 is used to apply clamping force from both sides of the sheet metal to be joined, thereby fixing the sheet metal in the working area at the top of the fixed frame 4, avoiding loosening or misalignment of the sheet metal during the joining operation, ensuring the alignment accuracy of the sheet metal joint, and improving the joining quality. The top of the moving plate 11 is rotatably connected to the linkage rod 13, and the side wall of the linkage rod 13 is rotatably connected to the side wall of the third rotating plate 14.

[0034] Working principle: During the movement and fixing phase of the device, the entire device is first pushed to the working position by the casters 2 at the bottom of the support 1. The motor 5 in the landing assembly is started. The output end of the motor 5 drives the first rotating plate 6 to rotate around the axis. Since the first rotating plate 6 is rotatably connected to the side wall of the second rotating plate 7, the rotation of the first rotating plate 6 will be converted into a pushing or pulling force on the second rotating plate 7. At this time, the sliding plate 9 connected to the other end of the second rotating plate 7 is constrained by the inner wall of the limiting plate 8 and can only move up and down in the vertical direction. Driven by the second rotating plate 7, the sliding plate 9 gradually extends downward until the anti-slip plate 10 at the bottom is tightly attached to the ground. The anti-slip plate 10 increases the friction with the ground and, together with the supporting effect of the sliding plate 9 on the support 1, counteracts the sliding or shaking caused by the casters 2, thereby stabilizing the device in the working position and providing a solid foundation for the subsequent plate joining operation.

[0035] Entering the plate clamping and joining stage, the plates to be joined are placed in the clamping area at the top of the fixed frame 4. The hydraulic cylinder 19 connected to the side wall of the second support block 17 is activated. The output end of the hydraulic cylinder 19 pushes the connecting frame 20 to move. The connecting frame 20 is rotated and connected to the moving plate 11 through the inner wall, which drives the moving plate 11 to move along the slide rail 16. The slider 21 at the bottom of the moving plate 11 slides and engages with the slide rail 16 to ensure a stable movement trajectory. At the same time, the linkage rod 13 at the top of the moving plate 11 rotates with the displacement of the moving plate 11. The third rotating plate 14 connected to the other end of the linkage rod 13 rotates synchronously around the rotating shaft 15, thereby driving the moving plate 11 on the other side to move closer to the middle. When the two moving plates 11 gradually approach each other, the clamping block 12 at the top of them will apply uniform pressure from both sides of the plate to achieve adaptive clamping of plates of different sizes and avoid loosening or misalignment of the plates during the joining process.
