Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to a frame welding conformal tooling. Background Technology

[0002] In machining, product inspection, assembly, and welding processes, users utilize a large amount of process equipment, or tooling, to install workpieces and ensure they are in the correct position, thereby guaranteeing the quality of parts and products and improving production efficiency. Welding tooling is essential in the automotive, motorcycle, and aircraft industries, as well as in pharmaceuticals; without welding tooling, there would be no product.

[0003] For example, patent (CN 219113275 U) discloses a frame welding fixture, including a base, a welding platform, a fixture body, and a lifting device. In this utility model, the fixture body is used to position and limit the workpiece, reducing the welding process and facilitating the welding work. After the workpiece cools down after welding, the lifting device is activated, and the workpiece is moved vertically upward so that its lower surface passes over the fixture body. Then, the lifting operation is carried out, avoiding collisions between the workpiece and the fixture during the lifting process. This ensures a high yield rate, improves welding efficiency, and reduces production costs.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: On the one hand, the traditional positioning method is extremely simple, only able to fix frames of specific specifications and sizes. When faced with frames of diverse sizes, it lacks a flexible and adjustable positioning mechanism, resulting in a significant reduction in the adaptability of the device and making it difficult to meet the welding needs of multi-specification frames in modern industrial production. On the other hand, most existing technologies only support single-sided welding of the frame. When performing reverse welding, it is necessary to frequently disassemble and re-clamp the frame, which is not only cumbersome and time-consuming, but also easily affects the welding accuracy due to secondary positioning errors. At the same time, it is not easy to flip the frame for double-sided welding, which seriously restricts the improvement of welding efficiency and greatly reduces the practicality and convenience of the device, making it difficult to adapt to the trend of efficient and automated welding production. Therefore, we designed a frame welding conformal tooling to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a frame welding conformal tooling to address the aforementioned technical problems. In use, two frames of different specifications are placed within two horizontal clamping plates. Then, an electric push rod is activated to apply pressure to the horizontal clamping plates, causing the two frames to come into contact with each other, creating a gap between them. Rotating the forward and reverse threaded rods then guides the vertical clamping plates on both sides along the outer sides of the horizontal clamping plates, effectively supporting both sides of the two frames. The inner side of the U-shaped bracket effectively supports the gap between the two frames, ensuring a horizontal connection between them. Therefore, it facilitates efficient welding between the two frames, greatly increasing welding efficiency and quality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A frame welding conformal tooling includes a welding table, with support seats rotatably connected to both ends of the welding table. Electric push rods are mounted on both sides of the two support seats that are close to each other. A horizontal clamping plate is fixed to the output end of the electric push rod. Vertical clamping plates are slidably connected to both sides of the two horizontal clamping plates. Both ends of the two vertical clamping plates are threaded with positive and negative threaded rods.

[0007] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, a transmission rod is fixed at the ends of the two support seats that are far apart from each other. The outer side of the transmission rod is rotatably connected to the welding table, and an angle turntable is fixed at the end of the transmission rod that is far away from the support seat.

[0008] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, pointers are fixed at both ends of the welding table, and the top of the pointers is slidably connected to the angle turntable.

[0009] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, a handle is fixed to one end of the angle turntable, and the connection between the handle and the angle turntable is offset from the center of the angle turntable.

[0010] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, a pressure plate is slidably connected to the inner side of the transverse clamping plate, and a screw is threaded to both sides of the top of the transverse clamping plate, with the bottom end of the screw being rotatably connected to the pressure plate.

[0011] As a preferred embodiment of the frame welding conformal tooling provided by this utility model, a U-shaped bracket is fixed to the inner side of the vertical clamping plate, a screw rod is threaded to the inner side of the U-shaped bracket, and a circular piece is fixed to the bottom end of the screw rod.

[0012] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, the top ends of the first screw and the second screw are fixed with anti-slip handwheels, and one end of the positive and negative threaded rod is fixed with a handwheel.

[0013] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, the bottom ends of the pressure plate and the circular piece are fixed with anti-slip pads.

[0014] In a preferred embodiment of the frame welding conformal tooling provided by this utility model, the vertical clamping plate and the U-shaped bracket are U-shaped, and the vertical clamping plate is U-shaped.

[0015] As a preferred embodiment of the frame welding conformal tooling provided by this utility model, the welding table has a rectangular groove inside, and the inner side of the rectangular groove is rotatably connected to the support base, the vertical clamping plate and the horizontal clamping plate.

[0016] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0017] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects: This utility model provides a frame welding conformal tooling. By activating an electric push rod, the horizontal clamping plate applies pressure to the frame. Then, rotating a screw drives a pressure plate to further position the frame, thereby maintaining the stability and horizontal alignment of the frame. Then, rotating the positive and negative threaded rods drives the vertical clamping plates on both sides to guide along the outer side of the horizontal clamping plate. The vertical clamping plates drive the U-shaped bracket and the screw pair to limit the position of both sides of the frame. The above-mentioned positioning is adjusted according to different frame specifications to facilitate the stability and convenience of the frame positioning device. By turning the throttle, the angle turntable, transmission rod, support base, horizontal clamping plate, vertical clamping plate and frame are rotated, so as to effectively weld the gap formed by the two frames on both sides, thereby increasing the welding effect and quality.

[0021] 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] As described in the background section, on the one hand, traditional positioning methods are extremely limited, only capable of fixing frames of specific sizes. When faced with frames of diverse sizes, the lack of a flexible and adjustable positioning mechanism significantly reduces the adaptability of the device, making it difficult to meet the welding needs of multi-size frames in modern industrial production. On the other hand, most existing technologies only support single-sided welding of the frame. When performing reverse welding, the frame needs to be frequently disassembled and repositioned. This process is not only cumbersome and time-consuming, but also highly susceptible to affecting welding accuracy due to secondary positioning errors. Furthermore, the inability to easily flip the frame for double-sided welding severely restricts the improvement of welding efficiency, greatly diminishing the practicality and convenience of the device and making it difficult to adapt to the trend of efficient and automated welding production.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1 Please refer to Figures 1-8 A frame welding conformal tooling includes a welding table 1, with support seats 2 rotatably connected to both ends of the welding table 1. The rotatable connection between the support seats 2 and the welding table 1 uses high-precision bearings to reduce friction during rotation, allowing the support seats 2 to rotate easily while ensuring smooth and accurate rotation. Electric push rods 7 are mounted on both sides of the two support seats 2, close to each other. The outer shell of the electric push rods 7 is made of high-strength protective material, providing waterproof, dustproof, and oil-proof functions, adapting to the harsh working environment of the welding workshop. A horizontal clamping plate 4 is fixed to the output end of the electric push rod 7. Vertical clamping plates 3 are slidably connected to both sides of the two horizontal clamping plates 4. The sliding connection between the vertical clamping plates 3 and the horizontal clamping plates 4 uses a linear guide slider mechanism. The linear guide has high precision and low friction characteristics, ensuring smooth operation and accurate positioning of the vertical clamping plates during sliding. Simultaneously, the inner side of the vertical clamping plates 3 adopts a reinforced U-shaped design, increasing the structural strength and rigidity of the vertical clamping plates, enabling them to withstand greater pressure and resist deformation when supporting the frame. Meanwhile, the opening size of the U-shaped structure can be adjusted according to the size of different frame specifications to meet the welding requirements of various frames. Both ends of the two vertical clamping plates 3 are threaded with positive and negative threaded rods 6. The inside of the welding table 1 is provided with a rectangular groove. The inner side of the rectangular groove is rotatably connected to the support base 2, the vertical clamping plate 3 and the horizontal clamping plate 4. The connection between the horizontal clamping plate 4 and the electric push rod 7 adopts a floating joint. This joint can compensate for the position deviation of the horizontal clamping plate during the movement to a certain extent, ensuring that the pressure applied by the electric push rod is evenly transmitted to the frame. The horizontal clamping plate 4 has guide grooves on both sides, which work in conjunction with the guide blocks on the vertical clamping plate 3 to provide precise guidance for the sliding of the vertical clamping plate, ensuring that the vertical clamping plate will not shift during the sliding process, thereby accurately supporting both sides of the frame. In use, two frames of different specifications are placed in two horizontal clamping plates 4. Then, the electric push rod 7 is activated to drive the horizontal clamping plates 4 to apply pressure to the frames, so that the two frames come into contact with each other. At this time, a gap is formed between the two frames. Then, by rotating the positive and negative threaded rod 6, the vertical clamping plates 3 on both sides are guided along the outside of the horizontal clamping plates 4, thereby effectively supporting the two sides of the two frames. The inner side of the U-shaped bracket 10 effectively supports the gap formed between the two frames, so as to maintain the horizontal connection between the two frames. Therefore, it is easy to weld the two frames together, greatly increasing the welding efficiency and quality. The surface of the hand-operated drum of the positive and negative threaded rod 6 is covered with non-slip rubber material, which increases the operator's grip and comfort when rotating the hand-operated drum, and at the same time prevents the hand-operated drum from slipping during operation. The hand-operated drum is equipped with scale marks, which makes it easy for the operator to accurately control the number of rotations of the positive and negative threaded rod, thereby precisely adjusting the position of the vertical clamp 3; A transmission rod 12 is fixed to one end of each of the two support seats 2 that are far apart from each other. The outer side of the transmission rod 12 is rotatably connected to the welding table 1. An angle turntable 5 is fixed to the end of the transmission rod 12 that is far away from the support seat 2. A pointer 14 is fixed to both ends of the welding table 1. The top of the pointer 14 is slidably connected to the angle turntable 5. A handle 13 is fixed to one end of the angle turntable 5. The connection between the handle 13 and the angle turntable 5 is offset from the center of the angle turntable 5. The pointer 14 can be used to effectively observe the rotation angle of the horizontal clamping plate 4, the vertical clamping plate 3, the frame and the angle turntable 5, thereby ensuring the accuracy of the frame flipping angle. Specifically, when welding the top surface between the two frames, it is also necessary to weld the bottom surface between the two frames. Therefore, it is necessary to turn the throttle 13 to drive the angle turntable 5, transmission rod 12, support seat 2, horizontal clamping plate 4, vertical clamping plate 3 and frame to rotate, so as to effectively weld the gap formed by the two frames on both sides, thereby increasing the welding effect and quality. The angle dial 5 has precise angle graduations on its surface, with an accuracy of 1°. Together with pointer 14, it accurately displays the rotation angles of the horizontal clamping plate 4, the vertical clamping plate 3, the frame, and the angle dial 5. The angle dial 5 is manufactured using high-precision processes to ensure the accuracy and clarity of the angle graduations, making it easy for operators to observe and read angle values. A pressure plate 8 is slidably connected to the inner side of the transverse clamping plate 4. Both sides of the top of the transverse clamping plate 4 are threaded with screws 9. The bottom end of the screws 9 is rotatably connected to the pressure plate 8. By rotating the screws 9, the pressure plate 8 is driven to position the frame, thereby maintaining the stability and level of the frame and preventing the frame from flipping and becoming loose.

[0027] Example 2 Please refer to Figure 9 and Figure 10A frame welding conformal fixture is provided, wherein a U-shaped bracket 10 is fixed to the inner side of a vertical clamping plate 3. The vertical clamping plate 3 and the U-shaped bracket 10 are U-shaped, and the vertical clamping plate 3 is U-shaped. A screw 11 is threaded to the inner side of the U-shaped bracket 10. A circular piece is fixed to the bottom end of the screw 11. An anti-slip pad is fixed to the bottom end of the pressure plate 8 and the circular piece. The vertical clamping plate 3 and the U-shaped bracket 10 limit the two sides of the frame, while the screw 11 drives the circular piece to effectively position the frame further, so as to ensure the horizontality between the two frames. The top ends of screw 9 and screw 11 are fixed with anti-slip handwheels, and one end of the positive and negative threaded rod 6 is fixed with a handwheel cylinder. The anti-slip handwheels fixed at the top ends of screw 9 and screw 11 have a textured surface to increase the friction when the operator rotates the handwheels and prevent the handwheels from slipping during operation. The threaded connection between the screw 9 and the transverse clamping plate 4 uses a fine thread, which has high adjustment accuracy and can precisely control the pressure of the pressure plate 8 on the frame by rotating the screw 9. The inner sliding connection between the pressure plate 8 and the transverse clamping plate 4 adopts a dovetail groove guide rail structure. The dovetail groove guide rail has good guiding and load-bearing capacity, which can ensure that the pressure plate slides smoothly in the transverse clamping plate, and can accurately and evenly apply pressure to the frame when positioning the frame.

[0028] The following is the usage process of the frame welding conformal tooling provided by this utility model: Place the two frames to be welded inside the two horizontal clamping plates 4 and the vertical clamping plates 3 respectively, and initially adjust the frame position so that the butt joint is within the U-shaped bracket 10. The electric push rod 7 pushes the horizontal clamping plate 4 to move towards the frame, and the floating joint automatically compensates for the position deviation. Rotate the hand-operated cylinder of the positive and negative thread rod 6 to move the vertical clamping plates 3 on both sides towards the frame simultaneously. The inner side of the U-shaped bracket 10 fits against the bottom surface of the frame, completing the initial lateral support. Rotate the anti-slip hand wheel at the top of the screw 1 9. The fine thread precisely controls the descent of the pressure plate 8. The pressure plate 8 descends smoothly along the dovetail groove guide rail. The bottom anti-slip pad contacts the upper surface of the frame. At the same time, rotate the anti-slip hand wheel at the top of the screw 2 11 to drive the circular piece to descend. The bottom anti-slip pad of the circular piece contacts the bottom surface of the frame, thereby effectively positioning the frame so as to effectively weld the two frames. After one side of the weld is completed, the frame is rotated 180° according to the angle adjustment process, and the back of the weld is welded to ensure good fusion of the welds on both sides.
