Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultra-clean pipeline spot welding technology in the semiconductor industry, and in particular to a quick correction tooling for pipe spot welding. Background Technology
[0002] With the rapid iteration of the semiconductor industry and related gas transport technologies, increasingly stringent challenges are being placed on production efficiency. Particularly in the gas transport sub-sector, spot welding of ultra-clean steel pipes is a crucial front-end process, and its production efficiency and quality directly impact the overall product chain's quality and cost. Currently, commonly available ultra-clean steel pipes are mainly divided into 1 / 4, 3 / 8, and 1 / 2 sizes. Spot welding of pipes primarily serves to provide fixation and concentricity for subsequent complete welding.
[0003] Traditional manual spot welding correction often involves clamping with pliers, which only increases the labor intensity of workers and is prone to damaging pipe components. This results in low production efficiency and makes it difficult to meet the demands of modern industry for high-efficiency and rapid production.
[0004] In view of the above problems, there is an urgent need in the market for a tooling that can quickly correct pipe fittings after spot welding, so as to improve efficiency and workpiece turnover. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model discloses a quick correction tooling for spot welding of pipe fittings.
[0006] The specific technical solution is as follows: This utility model relates to a quick-alignment fixture for spot welding pipe fittings, used for coaxial positioning of parts A and B during pipe fitting welding. The fixture includes a U-shaped clamping block, a base, and a shaft clamp. The base is a square block with one corner machined into a thin plate. A semi-circular clearance groove B is formed on one side of the thin plate, and a shaft hole B is formed on the other side. The U-shaped clamping block is a U-shaped body with two free ends. A semi-circular clearance groove A is formed on the inner side of one free end, and a shaft hole A is formed on the other free end. The shaft hole B and shaft hole A correspond to each other and are connected by a connecting shaft, enabling the U-shaped clamping block to rotate freely. The clearance grooves A and B are positioned correspondingly and, when engaged, form the outer diameter of the pipe fitting. Four screw holes are formed on the side of the base on the same side as the clearance groove B for installing the shaft clamp, which presses the U-shaped clamping block towards the base.
[0007] The shaft clamp includes a mounting base, a chuck, and a handle. The mounting base has four mounting holes, which correspond to the screw holes. The shaft clamp and the base are connected by screws. When the handle is pressed down, the elastic downward pressure of the chuck is aligned with the clearance grooves A and B.
[0008] The U-shaped clamping block is also U-shaped in the thickness direction and is clamped onto the thin plate of the base.
[0009] Select the U-shaped clamp and base with suitable clearance grooves A and B according to the outer diameter of different pipe fittings.
[0010] The shaft clamp can be replaced with a small cylinder.
[0011] Compared with the prior art, the present invention has the following beneficial technical effects: This invention enables rapid correction of misaligned welds after spot welding of pipe fittings, reducing the labor intensity of repeated manual handling of workpieces. Pipe fittings can be corrected directly at their workstation after spot welding, reducing manual labor intensity, improving efficiency, stabilizing quality, and enhancing the consistency of production efficiency and welding quality. Furthermore, the device has a simple structure, is easy to operate, and is suitable for the correction needs of various pipe fitting specifications, possessing strong practicality and promotional value.

Figure 6 The figure shows a schematic diagram of the U-shaped clamping block of this utility model: This utility model is a quick-alignment tooling for spot welding pipe fittings, used for coaxial positioning of parts A41 and B42 during the welding of pipe fitting 4. The tooling includes a U-shaped clamping block 1, a base 2, and a shaft clamp 5; the base 2 is a square block, with one corner machined into a thin plate, and a semi-circular clearance groove B22 is opened on one side of the thin plate, and a shaft hole B21 is opened on the other side; the U-shaped clamping block 1 is a U-shaped body with two free ends. 11. A semi-circular clearance groove A12 is provided on the inner side of one free end, and a shaft hole A13 is provided on the other free end; the shaft hole B21 and shaft hole A13 correspond to each other and are connected by a connecting shaft 3 to realize the free rotation of the U-shaped clamp 1; the clearance groove A12 and clearance groove B22 are in corresponding positions and, after being fastened, form the outer diameter of the pipe 4; four screw holes 23 are provided on the side of the base 2 on the same side as the clearance groove B22 for installing the shaft clamp 5, and the shaft clamp 5 presses the U-shaped clamp 1 toward the base 2.
[0015] Figure 7 The figure shows a three-dimensional structural diagram of the shaft clamp of this utility model: The shaft clamp 5 includes a mounting base, a chuck 52 and a handle 53. The mounting base has four mounting holes 51, which are positioned corresponding to the screw holes 23. The shaft clamp 5 and the base 2 are installed and connected by screws. When the handle 53 is pressed down, the elastic downward pressure of the chuck 52 is aligned with the clearance grooves A12 and B22.

After the material arrives, place the two parts of the pipe fitting 4 that are initially connected by spot welding, parts A41 and B42, in the relief groove B22, and place the misaligned weld at the relief groove B22. Flip the U-shaped clamp 1 so that the relief groove A12 and the relief groove B22 engage to clamp parts A41 and B42. Then press down the handle 53 of the shaft clamp 5 so that the clamp 52 presses down on the U-shaped clamp 1 to make the two parts A41 and B42, which are not on the same axis, coaxial and repair the misaligned weld.
