Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of welding technology, specifically to a clamping fixture for welding steel plates. Background Technology
[0002] In the field of steel plate welding, especially in the welding of corrugated plates, welding quality and efficiency have always been key concerns. Due to the unique groove structure of corrugated plates, it is essential to ensure precise alignment and firm fixation of the plates during welding; otherwise, problems such as weld misalignment and insufficient weld strength may occur, affecting product performance.
[0003] Currently, existing technologies for welding corrugated sheets have many shortcomings. On the one hand, sheet alignment relies heavily on manual measurement and adjustment, which is inefficient and makes it difficult to guarantee alignment accuracy, resulting in inconsistent weld widths and affecting welding quality. On the other hand, traditional clamping methods typically use simple clamps or jigs, which cannot effectively clamp the grooved structure of the corrugated sheet. During welding, the sheet is prone to shaking or displacement, resulting in welding defects such as porosity and incomplete penetration. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a clamping fixture for welding steel plates, which solves the technical problem in the prior art that the corrugated plates cannot guarantee alignment accuracy and are prone to shaking or displacement during the welding process.
[0005] According to one aspect, at least one embodiment of the present invention provides a clamping fixture for welding steel plates, comprising:
[0006] A base, wherein at least two spaced workbenches are provided on the base, the workbenches being used to place corrugated sheets, the corrugated sheets having a number of sequentially connected grooves;
[0007] An alignment device, comprising two push plates symmetrically slidably disposed on both sides of the worktable, wherein the push plates are capable of sliding towards each other to align the sides of the corrugated board located on the worktable.
[0008] A U-shaped frame is raised and lowered on the base. The two ends of the U-shaped frame are used to press the groove of the corrugated sheet. The U-shaped frame can be lowered to press the corrugated sheet onto the worktable.
[0009] For example, in at least one embodiment of the present invention, a clamping fixture for welding steel plates is provided, which also includes a telescopic component. The telescopic end of the telescopic component is connected to the U-shaped frame and is used to drive the U-shaped frame to rise and fall.
[0010] For example, in a clamping fixture for welding steel plates provided in at least one embodiment of this utility model, the alignment device further includes:
[0011] A slider is slidably disposed on the lower end face of the base. Two sliders are provided symmetrically and slide in opposite directions.
[0012] The connecting plate has two parts, and each connecting plate has a slider located on the same side at both ends. The connecting plate has a clearance groove for avoiding the base.
[0013] For example, in a clamping fixture for welding steel plates provided in at least one embodiment of this utility model, the alignment device further includes:
[0014] The connecting rod is provided in two parts, and one end of each connecting rod is hinged to one of the two sliders respectively.
[0015] A push block is slidably disposed at the lower end of the base. The push block is hinged to the other end of the two connecting rods. After the push block can slide, it drives the two sliders to slide through the two connecting rods.
[0016] For example, in a clamping fixture for welding steel plates provided in at least one embodiment of this utility model, the alignment device further includes:
[0017] A pusher is disposed at the lower end of the base and is used to push the push block to slide.
[0018] For example, in a steel plate welding clamping fixture provided in at least one embodiment of the present invention, a gap is provided on the base, the gap is located between the two workbenches, and the gap allows the welding slag generated during the welding process to pass through.
[0019] For example, in a steel plate welding clamping fixture provided in at least one embodiment of the present invention, the lower end of the base is also provided with a receiving groove, the receiving groove is slidably disposed below the gap, and the receiving groove is used to receive welding slag generated during the welding process.
[0020] For example, in a steel plate welding clamping fixture provided in at least one embodiment of the present invention, the base is further provided with heat-conducting strips. Two heat-conducting strips are provided and are symmetrically arranged on both sides of the gap. The heat-conducting strips extend upwards towards the side away from the gap. The heat-conducting strips are used to absorb the heat generated during the welding process and guide the welding slag falling during the welding process so that the welding slag enters the receiving groove through the gap.
[0021] For example, in a steel plate welding clamping fixture provided in at least one embodiment of the present invention, a placement platform is provided above the base, and the placement platform is used to place the welding device.
[0022] The beneficial effects of the embodiments of this utility model are as follows:
[0023] In this invention, the push plates symmetrically slidably mounted on both sides of the worktable in the alignment device can quickly align the sides of the corrugated sheet by sliding towards each other. Compared to traditional manual alignment methods, this structure significantly reduces alignment time and errors, ensuring seamless connection of sheet edges and preventing uneven welds and misalignment caused by positional deviations from the source, effectively improving the quality and consistency of the welded product. The U-shaped frame is lifted and mounted on the base, and its two ends can press down and tightly fit the groove when descending, firmly pressing the corrugated sheet onto the worktable, greatly improving weld strength and overall welding quality, and providing a reliable guarantee for high-quality welding operations.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] like Figures 1-3 As shown, it illustrates a clamping fixture for welding steel plates in one embodiment of the present invention.
[0036] In this example, the base 100 has two spaced-apart worktables 200 at both ends; the push plate 310 of the alignment device 300 can slide on both sides of the worktable 200; after sliding, the push plate 310 abuts against both sides of the corrugated plate and continues to push the corrugated plate to align the two corrugated plates. The U-shaped frame 400 can press the groove of the corrugated plate at both ends, and after the U-shaped plate descends, it avoids the protrusion of the corrugated plate to prevent damage to the corrugated plate.
[0037] In use, the corrugated sheet to be welded is first placed on the workbench 200 on the base 100. The two workbench 200s are spaced apart to facilitate the falling off of welding slag generated during the welding process. Then, the pusher 360 in the alignment device 300 is activated. In this example, the pusher 360 can be a cylinder. The telescopic end of the pusher 360 is connected to a push block 350. The push block 350 and the two sliders 320 are connected by two connecting rods 340. The two ends of the connecting rods 340 are respectively hinged to the push block 350 and the sliders 320, and the two connecting rods 340 are of equal length. The sliders 320 and the push plate 310 are connected by a connecting plate 330. The connecting plate 330 is provided with a U-shaped clearance groove 331, which allows the alignment device 300 to avoid the base 100 during use.
[0038] The pusher 360 pushes the push block 350 to slide at the lower end of the base 100. When the push block 350 slides, the hinged connecting rod 340 drives the two sliders 320 to slide in opposite directions on the lower end face of the base 100, thereby causing the two push plates 310 connected to the sliders 320 to slide towards each other on both sides of the worktable 200, and the sliding distance of the two push plates 310 is equal; after aligning the sides of the corrugated plate on the worktable 200, the push plates 310 stop sliding.
[0039] In this example, the pusher 360, push block 350, connecting rod 340 and slider 320 are located at the lower end of the base 100, which can prevent welding slag from falling onto it during the welding process and affecting the movement accuracy of the alignment device 300, and can protect the alignment device 300.
[0040] After alignment, activate the telescopic component 500. In this example, the telescopic component 500 can be a cylinder. The telescopic end of the telescopic component 500 drives the U-shaped frame 400 to descend. The two ends of the U-shaped frame 400 press against the groove of the corrugated plate, pressing the corrugated plate firmly onto the worktable 200, so that the corrugated plate remains stable during welding and avoids affecting the welding quality due to shaking.
[0041] During the welding process, the generated welding slag falls through the gap 600 on the base 100 located between the two workbenches 200. Heat-conducting strips 800 are symmetrically arranged on both sides of the gap 600. In this example, the heat-conducting strips 800 can be made of copper. The heat-conducting strips 800 extend upwards at an angle away from the gap 600, absorbing the heat generated during welding and guiding the falling welding slag. This allows the welding slag to fall smoothly through the gap 600 into the receiving groove 700 below. The receiving groove 700 is slidably mounted on the base 100. When it is necessary to clean the welding slag from the receiving groove 700, the receiving groove 700 can be removed.
[0042] In addition, the placement platform 900 above the base 100 can be used to place the welding device; in this example, a welding trolley can be used. The placement platform 900 facilitates the movement of the welding trolley, improving welding efficiency. After welding is completed, the U-shaped frame 400 is raised by the telescopic component 500, and then the alignment device 300 is controlled to reset the push plate 310, allowing the welded corrugated plate to be removed.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
