Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a portable single-operator welding fixture. Background Art

[0002] In modern production practice, welding is a common processing method in production. Welding is a common processing method for connecting two or more parts into a component, and the obtained component usually has high strength in all directions. Welding methods are widely used in the manufacture of products ranging from simple daily necessities to complex transportation tools and facilities. With the continuous development of welding technology, modern welding technology can meet the welding requirements of high welding speed, high efficiency, and high quality.

[0003] A welding tooling fixture can accurately position and reliably clamp the welded parts, facilitating the assembly and welding of the welded parts and ensuring the process equipment requirements for the structural accuracy of the welded parts. Therefore, actively promoting and using tooling fixtures adapted to the product structure in modern welded part production is of great significance for improving product quality. In the actual operation process, welders need to place the parts to be welded into the welding fixture and use the welding fixture to clamp the parts to be welded for welding work. A welding fixture is a fixture that can accurately weld the welded parts according to the required welding parts, improve the assembly accuracy and efficiency, and prevent welding deformation.

[0004] Existing welding fixtures have certain disadvantages and deficiencies. Although they can clamp the parts to be welded at a certain angle for welding operations, they cannot adjust the angle of the welded parts according to actual needs when the welding parts need to be changed. Therefore, existing welding fixtures have certain limitations in actual applications. Content of the Utility Model

[0005] The purpose of the utility model is to provide a portable single-operator welding fixture to solve the problem that the welding fixture cannot adjust the angle of the welded parts according to actual needs.

[0006] To achieve the above purpose, the basic scheme provided by the utility model is: a portable single-operator welding fixture, including a cylinder, a triangular plate II is fixedly connected to the cylinder, a base II is fixedly connected to the triangular plate II, a triangular plate I is slidably connected to one side of the cylinder relative to the triangular plate II, a limiting component for restricting the movement of the triangular plate I is arranged on the cylinder, a base I is fixedly connected to the triangular plate I, and clamping components for clamping the welded parts on the triangular plate I and the triangular plate II are respectively arranged on the base I and the base II.

[0007] The principle and beneficial effects of the present utility model are as follows: By arranging a limiting component on one side of the cylinder, the movement of the first welded part along the semi-circumference of the cylinder is restricted, and the angle of the first welded part is adjusted to a certain extent. On the other side of the cylinder, the second welded part is placed relatively statically. The second welded part can appropriately adjust its own position according to the position of the first welded part after the angle adjustment until the welded parts are adjusted to the required angle and placed. Then, the welded parts are clamped by the clamping component, and the welded parts can be welded. The present utility model facilitates adjusting the welded parts to the required angle for welding work, and has a simple structure and is easy to operate.

[0008] Solution 2, which is the optimization of the basic solution. The limiting component includes a bolt. A chute is opened on the cylinder. The bolt is movably connected in the chute. The bolt is fixedly connected to the first triangular plate. A first nut is threadedly connected to the bolt. Taking the bolt as an intermediary, the first triangular plate is moved along the chute to adjust the angle of one of the welded parts, and the adjusted angle is locked by the first nut, which facilitates adjusting the angle of the welded part and locking the adjusted angle.

[0009] Solution 3, which is the optimization of the basic solution. The clamping component arranged on the first base includes an adjusting screw rod and a second nut. The second nut is fixedly connected to the first base. The adjusting screw rod is threadedly connected to the second nut. The clamping components arranged on the first base and the second base have the same structure. The adjusting screw rod can continuously approach the welded part through the threaded connection with the second nut, which facilitates the movement of the adjusting screw rod towards the welded part to clamp the welded part.

[0010] Solution 4, which is the optimization of Solution 3. A handle is provided on the adjusting screw rod. It is more convenient and labor-saving to drive the adjusting screw rod through the handle.

[0011] Solution 5, which is the optimization of Solution 4. A third nut is rotatably connected to the end of the adjusting screw rod away from the handle. The third nut increases the contact area between the clamping component and the welded part, and can effectively reduce the damage degree to the welded part during the clamping process.
