Description

Technical Field

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

[0002] Metal welding auxiliary fixtures are tooling devices used to assist in the metal welding process. They are typically used to fix and support the workpieces to be welded, so that welding operators can perform welding work more conveniently and stably. Metal welding auxiliary fixtures are usually designed in various forms to suit specific welding tasks and workpiece shapes in order to improve welding quality and production efficiency. When welding a workpiece, the workpiece needs to be placed in the fixture, the fixture is operated to hold the workpiece, and then the welding operation is performed.

[0003] Currently, when welding workpieces, the angle needs to be adjusted according to the welding progress. Angle adjustment facilitates subsequent welding operations by humans. However, most angle adjustments are operated by power devices. In actual use, angle adjustment needs to be combined with the actual operating angle of the operator. The adjustment method of power devices is too rigid and cannot be better coordinated with the operator.

[0004] Therefore, it is necessary to provide adjustable-angle metal welding auxiliary fixtures to solve the above-mentioned technical problems. Utility Model Content

[0005] In response to the above situation and to overcome the defects of the existing technology, this utility model provides an adjustable angle metal welding auxiliary fixture. Currently, angle adjustment is operated by a power device. However, in actual use, angle adjustment needs to be adjusted according to the actual operating angle of the operator. The adjustment method of the power device is too rigid and cannot be better coordinated with the operator.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adjustable-angle metal welding auxiliary fixture includes: a bracket, a support shaft, a mounting plate, and a clamping mechanism;

[0008] A support shaft is installed on the top left side of the bracket. Limiting plates are installed at intervals on the left extension end of the support shaft. An mounting plate is installed on the shaft between the limiting plates. The mounting plate is a disc structure with a hole pre-drilled in its middle to match the support shaft. A clamping mechanism is installed on the left side of the mounting plate, and a rotating rod is installed on the outer circumference of the mounting plate.

[0009] In one embodiment, a locking plate is installed on the right side of the mounting plate, and a frosted plate is installed on the inner wall of the right end of the locking plate. The frosted plate is a semi-circular ring structure.

[0010] In one embodiment, the support shaft has an installation port at the top inside the locking plate, and a double-headed cylinder is installed in the installation port. Push rods are installed at the upper and lower parts of the double-headed cylinder, and the extended ends of the push rods are connected to the locking block. The locking block has an arc-shaped structure, and a friction groove is provided on its top surface. The internal structure of the friction groove is matched with that of the frosted plate.

[0011] In one embodiment, the clamping mechanism comprises a fixed plate, a lower clamping plate, an upper clamping plate, a connecting rod, and a hydraulic rod. The fixed plate has two sets of clamping plates arranged at the top and bottom. The lower clamping plate is installed on the top surface of the bottom fixed plate, and the lower clamping plates are spaced apart in two sets. The upper clamping plate is installed on the bottom surface of the top fixed plate, and the upper clamping plate is located above the spacing of the lower clamping plates. The upper clamping plate is connected to the hydraulic rod via the connecting rod.

[0012] In one embodiment, the lower clamping plate and the inner wall of the lower clamping plate are equipped with anti-slip pads.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model fixes the workpiece by placing the workpiece inside the lower clamping plate and starting the hydraulic rod to drive the upper clamping plate to move down. The angle of the mounting plate is adjusted by manually rotating the rotating wheel rod, so that the mounting plate rotates under the limit of the support shaft and the limiting plate. This makes it convenient for manual adjustment of the angle, saves the operation and adjustment time, and improves the work efficiency. It makes the fixture more suitable for actual use and can adapt the fixture to the usage habits of different workers.

[0015] (2) This utility model allows the clamping mechanism to be adjusted to the required angle by manually rotating the rotating wheel rod. Then, the double-headed cylinder is activated, and the locking block is moved toward the frosted plate by the push rod until the friction groove abuts against the frosted plate, thus continuously locking the overall adjustment mechanism. The stability of use is improved by setting the locking component. Attached Figure Description

[0022] like Figures 1-2 As shown, the adjustable angle metal welding auxiliary fixture provided by this utility model includes: a bracket 1, a support shaft 2, a mounting plate 3, and a clamping mechanism 4.

[0023] like Figures 1-3 As shown, a support shaft 2 is installed on the top left side of the bracket 1. Limiting plates 21 are installed at intervals on the left extension end of the support shaft 2. An mounting plate 3 is installed on the shaft between the limiting plates 21. The mounting plate 3 is a disc structure with a hole pre-drilled in its middle to match the support shaft 2. A clamping mechanism 4 is installed on the left side of the mounting plate 3. A rotating wheel rod 31 is installed on the outer circumference of the mounting plate 3. During operation, the workpiece is placed into the clamping mechanism 4 and clamped. The angle of the mounting plate 3 is adjusted by manually rotating the rotating wheel rod 31, so that the mounting plate 3 rotates under the limitation of the support shaft 2 and the limiting plates 21, thereby clamping the workpiece in the clamping mechanism 4.

[0024] Preferably, in one embodiment, such as Figures 3-4 As shown, a locking plate 32 is installed on the right side of the mounting plate 3, and a frosted plate 33 is installed on the inner wall of the right end of the locking plate 32. The frosted plate 33 is a semi-circular ring structure.

[0025] Preferably, in one embodiment, such as Figure 4 As shown, the support shaft 2 has an installation port 22 at the top inside the locking plate 32. A double-headed cylinder 23 is installed inside the installation port 22. Push rods 24 are installed on both the upper and lower parts of the double-headed cylinder 23. The extended ends of the push rods 24 are connected to the locking block 25. The locking block 25 has an arc-shaped structure and a friction groove 26 on its top surface. The internal structure of the friction groove 26 matches the frosted plate 33. During operation, the clamping mechanism 4 is adjusted to the required angle by manually rotating the rotating wheel rod 31. Then, the double-headed cylinder 23 is activated, and the locking block 25 is moved toward the frosted plate 33 by the push rods 24 until the friction groove 26 abuts against the frosted plate 33, thus continuously locking the overall adjustment mechanism.

[0026] Preferably, in one embodiment, such as Figure 3 As shown, the clamping mechanism 4 consists of a fixed plate 41, a lower clamping plate 42, an upper clamping plate 43, a connecting rod 44, and a hydraulic rod 45.

The upper clamping plate 43 is connected to the hydraulic rod 45 through the connecting rod 44. During operation, by placing the workpiece inside the lower clamping plate 42, the hydraulic rod 45 is activated to move the upper clamping plate 43 downward, thereby fixing the workpiece.

[0027] Preferably, in one embodiment, the inner walls of the lower clamping plate 42 and the lower clamping plate 43 are equipped with anti-slip pads 46 to improve the stability of the workpiece placement.

[0028] Working principle of this utility model:

[0029] During operation, the workpiece is placed inside the lower clamping plate 42, and the hydraulic rod 45 is activated to move the upper clamping plate 43 downward, fixing the workpiece. The angle of the mounting plate 3 is adjusted by manually rotating the rotating wheel rod 31, allowing the mounting plate 3 to rotate under the constraints of the support shaft 2 and the limiting plate 21. After manually rotating the rotating wheel rod 31 to adjust the clamping mechanism 4 to the required angle, the double-headed cylinder 23 is activated, and the locking block 25 is moved towards the abrasive plate 33 via the push rod 24 until the friction groove 26 abuts against the abrasive plate 33, continuously locking the overall adjustment mechanism. The above embodiment is only one of the preferred embodiments of this utility model and should not be used to limit the protection scope of this utility model.
