Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a welding device for parts. 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 welding process is heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. After the molten pool cools, the workpieces can be welded together.

[0003] A search revealed a welding apparatus for metal parts, publication number CN213105222U, comprising a base, a transverse translation platform, a rotating platform, a speed regulating mechanism, and a molten metal output mechanism. The rotating platform has a rotating shaft perpendicular to the base; the rotating shaft is inserted into a bearing on the transverse translation platform; the transverse translation platform also has a rotary drive motor, with a drive gear mounted on the output shaft of the rotary drive motor, and the rotating platform has an external gear meshing with the drive gear; the rotary drive motor drives the rotating platform to rotate; the speed regulating mechanism includes a speed regulating rod mounted on the base; the molten metal output mechanism includes a support column, a crossbar, and a nozzle for outputting molten metal; the crossbar is fixed to the top of the support column, and the nozzle is located at the end of the crossbar. This welding apparatus for metal parts is easy to implement and easy to precisely control.

[0004] The welding device for metal parts described above is easy to implement and easy to control precisely, but it is not adequate in terms of fixing the parts during processing. Unstable clamping can lead to problems such as welding dimensional deviations and weak strength. Therefore, we provide a welding device for parts. Utility Model Content

[0030] Please see Figures 1-3 This is the first embodiment of the present invention.

[0031] This embodiment provides a welding device for parts, including a work platform 1, and further including: a placement component 2 for placing the processed parts is installed on the top of the work platform 1, the placement component 2 includes a support column 21 fixedly installed on the top of the work platform 1, and a connecting column 22 is detachably installed on the top of the support column 21.

[0032] A mounting plate 23 is detachably installed on the back of the connecting column 22. An inner positioning column 24 is fixedly installed on the surface of the mounting plate 23. An outer contour mounting column 25 is fixedly installed on the top of the working platform 1. An outer contour support arm 26 is bolted to the side of the outer contour mounting column 25.

[0033] Specifically, a clamping assembly 3 is installed at the top of the outer contour mounting post 25. The clamping assembly 3 includes a pneumatic lifting rod 31 fixedly installed inside the outer contour mounting post 25, and a lifting plate 32 is fixedly installed at the top of the pneumatic lifting rod 31. A side connecting post 33 is bolted to the side of the lifting plate 32, and a clamping arm 34 is bolted to the side connecting post 33 and the surface of the lifting plate 32.

[0034] Furthermore, the pneumatic lifting rod 31 drives the lifting plate 32 to move up and down, thereby driving the side connecting column 33 and the clamping arm 34 on the lifting plate 32. By moving the clamping arm 34 down to the surface of the part, the part is precisely fixed, reducing the problem of clamping instability caused by traditional clamping and affecting normal welding.

[0035] In use, the part is placed on the top of the connecting column 22 and the outer contour support arm 26. The positioning hole on the surface of the part is aligned with the inner positioning column 24, and the surface of the part is aligned with the groove on the surface of the outer contour support arm 26. The part is initially fixed on the top of the device. Then, the pneumatic lifting rod 31 is activated. The pneumatic lifting rod 31 drives the lifting plate 32 to move up and down, thereby driving the clamping arm 34 on the side connecting column 33 and the lifting plate 32. By moving the clamping arm 34 down to the surface of the part, the part is accurately fixed, reducing the instability of clamping caused by traditional clamping and avoiding affecting normal welding.

[0036] In summary, the inner positioning column 24 and the outer contour support arm 26 are used to initially fix the part at the top of the device. The pneumatic lifting rod 31 drives the lifting plate 32 to move up and down, thereby driving the side connecting column 33 and the clamping arm 34 on the lifting plate 32. By moving the clamping arm 34 down to the surface of the part, the part is precisely fixed, reducing the instability of clamping caused by traditional clamping and the problem of affecting normal welding, improving the production efficiency of the part, and improving the welding strength and dimensional stability of the part.

[0037] Example 2:

[0038] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0039] Specifically, a welding assembly 4 is installed at the top of the work platform 1. The welding assembly 4 includes a vertical mounting column 41 fixedly installed at the top of the work platform 1. A mounting groove 42 is formed on the surface of the vertical mounting column 41, and a sliding plate 43 is detachably mounted on the surface of the mounting groove 42. A slider 44 is movably mounted on the surface of the sliding plate 43, and an electric push rod 45 is fixedly mounted at the top of the slider 44. A limiting plate 46 is fixedly mounted at the end of the sliding plate 43, and mounting bolts 47 are detachably installed between the limiting plate 46 and the interior of the vertical mounting column 41. A welding connecting plate 48 is bolted to the side of the slider 44, and a welding gun 49 is fixedly mounted inside the welding connecting plate 48.

[0040] Furthermore, the electric push rod 45 drives the slider 44 to move on the slide plate 43, which in turn moves the welding connection plate 48 and the welding gun 49 fixedly mounted on its surface up and down, thereby welding the surface of the part. The adjustable height welding gun 49 can quickly place the part without affecting normal work, and also facilitates welding of parts of different heights.

[0041] In use, the slide plate 43 is fixedly installed inside the mounting groove 42 opened in the vertical mounting column 41 by the mounting bolt 47. The electric push rod 45 is activated, and the electric push rod 45 drives the slider 44 to move on the slide plate 43. The limit plate 46 prevents the slider 44 from falling off the surface of the slide plate 43. When the slider 44 moves up and down, the movement of the slider 44 drives the welding connection plate 48 and the welding gun 49 fixedly installed on its surface to move up and down, thereby welding the surface of the part.

[0042] In summary, the electric push rod 45 drives the slider 44 to move on the slide plate 43, which in turn moves the welding connection plate 48 and the welding gun 49 fixedly mounted on its surface up and down, thereby welding the surface of the parts. The adjustable height welding gun 49 allows for quick placement of parts without affecting normal operation and facilitates welding of parts of different heights.
