Description

Technical Field

[0001] This application relates to the field of laser welding of pump bodies, and in particular to a fixture for laser welding of pump body components. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The laser heat source heats up the material and melts it. As the laser beam moves, the molten material cools and solidifies, thus forming a continuous weld. Laser welding has many advantages such as fast welding speed, small heat-affected zone, and easy integration. Currently, laser welding technology is widely used to join high-melting-point metals.

[0003] In related technologies, the metal components in oil pumps have irregular shapes. During laser welding, shims need to be added or removed from the bottom of the fixture to adjust the welding angle according to the shape of the metal components so that the laser can irradiate the welding area. However, it is difficult to accurately irradiate the welding area, making the adjustment difficult. Summary of the Invention

[0004] To improve the accuracy of laser welding, this application provides a fixture for laser welding of pump body components.

[0005] The fixing fixture for laser welding of pump body components provided in this application adopts the following technical solution:

[0006] A fixture for laser welding of pump body components includes a base and a laser generator. A base is provided on the base, a fastening device for fixing the metal components is provided on the base, and an adjustment mechanism for adjusting the offset angle of the base is provided on the base.

[0007] By adopting the above technical solution, the adjustment mechanism can quickly adjust the offset angle of the base, causing the metal components fixed to the base by the fastening device to shift. This exposes the area of ​​the metal component to be welded to an angle convenient for laser irradiation, allowing the laser emitter to weld the metal component. This minimizes the preparation time for welding the metal components and maximizes the efficiency of welding.

[0008] Optionally, the adjustment mechanism includes several adjustment discs, with a base positioned between adjacent adjustment discs. A rotating rod is mounted on the base, with both ends of the rotating rod rotatably connected to the corresponding adjustment discs.

[0009] By adopting the above technical solution, the base can rotate on the adjustment plate via a rotating rod, and its offset angle can be adjusted by the angle of rotation of the base.

[0010] Optionally, the adjustment mechanism also includes an adjustment rod, which is mounted on the base away from the rotating rod. Several adjustment discs are provided with adjustment holes, and the adjustment rod extends into the adjustment hole and moves along the length of the adjustment hole.

[0011] By adopting the above technical solution, the movement of the adjusting rod within the adjusting hole can limit the maximum and minimum angles at which the base can rotate.

[0012] Optionally, the adjusting rod is provided with an adjusting handle, which is located on the side of the adjusting plate away from the base. The adjusting handle is threadedly connected to the adjusting rod, and the adjusting handle moves along the adjusting rod towards or away from the base.

[0013] By adopting the above technical solution, the adjustment handle allows the user to easily adjust the offset angle of the base. After adjustment, the adjustment handle can be fixed on the adjustment plate by the threaded engagement between the adjustment handle and the adjustment rod, thereby fixing the angle of the base after offset.

[0014] Optionally, the adjustment hole is arc-shaped, and an angle gauge is provided on the adjustment plate, with the angle gauge concentrically set with the arc.

[0015] By adopting the above technical solution, the angle gauge on the adjustment plate can intuitively show the angle of the base offset. At the same time, the angle to be adjusted can be calculated according to the drawings of the metal components. Then, by observing the angle gauge, the position of the metal components that needs to be welded can be quickly exposed.

[0016] Optionally, the fastening device includes a fixing post, which is mounted on the base. A fixing groove is provided on the side of the fixing post away from the base, and a metal component is placed in the fixing groove.

[0017] By adopting the above technical solution, the metal components are inserted into the fixed groove, which can minimize the risk of the metal components falling off when the base is adjusted to offset the angle.

[0018] Optionally, a fixing plate is axially sleeved on the fixing column, and the fixing plate is provided with several claws that slide toward or away from the center of the fixing column.

[0019] By adopting the above technical solution, several claws further fix the metal components on the fixed column, and at the same time, the movement of the claws can match metal components of different specifications.

[0020] Optionally, bolts are provided on several jaws, which pass through the jaws and are threadedly connected to the fixed plate.

[0021] By adopting the above technical solution, the chuck can adjust its movement on the fixed plate by rotating the bolt to move the bolt closer to or further away from the fixed plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This allows metal components to be quickly exposed at the welding locations, minimizing preparation time before welding and maximizing work efficiency in welding metal components.

[0024] 2. It can fix and weld metal components of different specifications, which can reduce the time for changing molds during welding. Attached Figure Description
