Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, and in particular to an angle-adjustable welding fixture. Background Technology

[0002] In the manufacturing process of shipping containers, it is often necessary to assemble and weld sheet metal or structural steel at specific angles according to the design drawings. Before this step, the workpieces to be welded must be precisely fixed in that angled position.

[0003] Currently, the common practice is to first place the workpiece at an approximate angle, mark it, and then temporarily fix it by spot welding. Measuring tools are then used to check if the angle meets the requirements. This process is cumbersome, relies heavily on the operator's experience, and has inconsistent accuracy. While some general-purpose clamping devices exist, they typically have significant drawbacks: First, these devices often require clamping the workpiece along with the welding platform, greatly limiting operational flexibility and site adaptability. Second, when welding two workpieces at an angle, multiple clamping devices are usually needed to fix them at different points. This is not only complex to set up but also particularly difficult for achieving non-standard angles, easily leading to workpiece displacement or rotation during welding due to insecure fixing, directly affecting welding dimensional accuracy and finished product quality. Furthermore, when post-weld dimensional deviations require rework, frequent clamping and loosening operations are not only inefficient but also prone to wear and tear on the fixtures themselves. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an angle-adjustable welding fixture with a simple structure that effectively improves efficiency and flexibility.

[0005] The main contents of this utility model include: a base, which includes a first clamping seat and a second clamping seat; A hinge mechanism is provided, which connects one end of the first clamping seat and the second clamping seat, so that the two can rotate relative to each other about the axis of the hinge mechanism to adjust the included angle. An angle limiting mechanism is used to fix the first clamping seat and the second clamping seat at a set included angle position; At least two sets of clamping mechanisms are respectively installed on the first clamping seat and the second clamping seat, for clamping and fixing the workpiece placed thereon.

[0006] Preferably, the angle limiting mechanism includes a limiting rod, a guide post, and a tightening nut; one end of the limiting rod is rotatably connected to the end of the first clamping seat away from the hinge mechanism, and a guide hole extending along the length direction is provided on it; the guide post is fixed to the end of the second clamping seat away from the hinge mechanism, and is slidably inserted into the guide hole and threadedly engaged with the tightening nut. By tightening the tightening nut, it can be made to abut against the limiting rod, thereby clamping and fixing the limiting rod between the second clamping seat and the tightening nut, thus achieving angle fixation.

[0007] Preferably, both the first clamping seat and the second clamping seat are configured as U-shaped structures, each including a first side plate, a bottom plate, and a second side plate, wherein the first side plate and the second side plate are perpendicularly disposed on opposite sides of the bottom plate. The first side plate, the bottom plate, and the second side plate together form a clamping space for accommodating the workpiece, and the first side plate is used to provide a reference surface for clamping and positioning the workpiece.

[0008] Preferably, the hinge mechanism is fixedly connected to the first side plate of the first clamping seat and the second clamping seat respectively.

[0009] Preferably, the clamping mechanism includes a fixing nut disposed on the second side plate and a clamping screw threadedly engaged with the fixing nut. The first end of the clamping screw passes through the second side plate and extends into the clamping space to clamp the workpiece.

[0010] Preferably, the second end of the clamping screw is provided with an operating handle for driving the clamping screw to rotate to adjust its insertion depth, adapt to and clamp workpieces of different widths, and the second end of the clamping screw is axially opposite to the first end.

[0011] Preferably, the second end of the tightening screw has a radially through hole, and the operating handle is slidably inserted into the through hole. The operating handle is pulled radially to adjust the tightening torque.

[0012] Preferably, a pad is provided at the first end of the tightening screw.

[0013] The beneficial effects of this utility model are as follows: By connecting the two clamping seats through the hinge mechanism, the included angle can be adjusted steplessly and continuously, which can quickly adapt to the welding angle required by different drawings, effectively improving the versatility and flexibility of the fixture; the angle limiting mechanism, through the cooperation of the limiting rod, guide column and tightening nut, can form a stable triangular support structure after the angle is set, which effectively enhances the stability of the fixture and ensures that the included angle will not change due to external force during the welding process, thereby ensuring the accuracy and consistency of the welding angle and significantly improving the welding quality.

[0015] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-2 As shown, this application proposes an angle-adjustable welding fixture, mainly used for the assembly and welding of structural steel or sheet metal during container manufacturing. The fixture mainly includes a base 1, a hinge mechanism 2, an angle limiting mechanism 3, and a clamping mechanism 4. The base 1 consists of a first clamping seat 11 and a second clamping seat 12, which are connected by the hinge mechanism 2, allowing relative rotation to adjust the clamping angle. The angle limiting mechanism 3 is used to fix the angular position of the two clamping seats, while the clamping mechanism 4 is used to clamp the workpiece to form a stable triangular support welding platform. This fixture enables rapid clamping and fixing of two workpieces 5 at a set angle, effectively improving welding accuracy and efficiency.

[0017] like Figure 1-2 As shown, the base 1 includes a first clamping seat 11 and a second clamping seat 12 symmetrically arranged, both of which are U-shaped structures. Taking the first clamping seat 11 as an example, it includes a first side plate 111, a base plate 112, and a second side plate 113. The first side plate 111 and the second side plate 113 are perpendicularly arranged on opposite sides of the base plate 112, together forming a U-shaped clamping space for accommodating the workpiece 5 (such as structural steel or plate). The first side plate 111 serves as the reference surface for clamping the workpiece 5, ensuring that the workpiece 5 does not shift during clamping, effectively improving the accuracy of the welding position and ensuring welding precision.

[0018] like Figure 1-2 As shown, the hinge mechanism 2 is connected between the first side plates 111 of the first clamping seat 11 and the second clamping seat 12, allowing the two to rotate relative to each other around the axis of the hinge mechanism. The included angle between the two clamping seats can be flexibly adjusted according to welding requirements, adapting to welding needs at different angles and effectively improving versatility and flexibility. In specific embodiments, the hinge mechanism 2 can adopt a hinge structure or a pin connection method, without specific limitations.

[0019] like Figure 1-2As shown, the angle limiting mechanism 3 includes a limiting rod 31, a guide post (not shown), and a tightening nut 33. One end of the limiting rod 31 is rotatably connected to the end of the first clamping seat 11 away from the hinge mechanism 2, and a guide hole 32 extending along its length is provided on it. The guide post is fixed to the end of the second clamping seat 12 away from the hinge mechanism 2 and can be slidably inserted into the guide hole 32. The tightening nut 33 is threadedly engaged with the guide post. When the two clamping seats rotate to the desired angle, the tightening nut 33 presses against the limiting rod 31, thereby fixing the limiting rod 31 between the second clamping seat 12 and the tightening nut 33 to lock the angle. When the tightening nut 33 presses against the limiting rod 31, the limiting rod 31 and the two clamping seats form a stable triangular support structure, which can effectively enhance the overall stability of the fixture and prevent angle changes due to force during welding. In addition, the tightening nut is easy to operate, allowing for quick angle fixing and release, and is suitable for multiple adjustments.

[0020] like Figure 1-2 As shown, each clamping seat is equipped with at least one clamping mechanism 4. Each clamping mechanism 4 includes a fixing nut 41 and a clamping screw 42 threadedly connected to it. The fixing nut 41 is fixed to the second side plate 113. The first end of the clamping screw 42 passes through the second side plate 113 and extends into the clamping space to clamp the workpiece 5; the second end is equipped with an operating handle 43 for easy rotation and adjustment. The second end and the first end of the clamping screw 42 are axially opposite each other. The clamping screw 42 adjusts its clamping force by screwing it in, adapting to workpieces of different thicknesses or widths, thus improving the versatility of the fixture.

[0021] Furthermore, a pad 44 is provided at the first end of the tightening screw 42 to prevent the tightening screw 42 from directly contacting the surface of the workpiece 5 and causing wear to the workpiece. In a specific embodiment, the pad 44 can be made of a material with anti-slip properties to improve the stability of clamping the workpiece.

[0022] Preferably, the second end of the clamping screw 42 is provided with a radial through hole, through which the operating handle 43 slides and can be pulled out radially to increase torque and achieve a more secure clamping.

[0023] In this specific embodiment, each clamping seat is provided with two sets of clamping mechanisms 4, so that the workpiece 5 is subjected to uniform clamping force and the clamping stability is improved.

[0024] Working principle: In use, first loosen the tightening nut 33 of the angle limiting mechanism 3. Then, according to welding requirements, rotate the first clamping seat 11 and the second clamping seat 12 around the hinge mechanism 2 to the desired angle, and then tighten the nut 33 again to lock them in place. Next, place the two workpieces 5 to be welded into the clamping spaces of the first clamping seat 11 and the second clamping seat 12 respectively, aligning them initially so that one side of the workpiece is pressed against the first side plate 111. Finally, rotate the tightening screws 42 on both clamping seats until the pad 44 firmly presses against the workpiece 5, securely clamping it onto the first side plate 111, and then perform welding. After welding is complete, rotate the tightening screws 42 and tighten the nut 33 in the opposite direction to directly remove the welded workpiece.
