Description

Technical Field

[0001] The utility model relates to the field of automobile processing, and particularly relates to a flexible aluminum spot welding device for automobile door reinforcement plates. Background Art

[0002] At present, in the automotive industry, the difficulty of aluminum welding is relatively high. Most automobile manufacturers will choose SPR riveting and blind riveting welding processes for aluminum plate connection. The disadvantages of the above SPR riveting and blind riveting are that the required rivet cost is high, which will cause the parts to become heavier; and the production rhythm of SPR riveting and blind riveting is slower than that of aluminum spot welding, resulting in low production efficiency. Now, there is a welding method that combines a large-pressure welding gun with 8000N and a high-power welding machine with a 5KVA current output, which has problems such as surface cracks in aluminum spot welding, welding spatter in aluminum spot welding, and adhesion between the electrode head and aluminum during the welding process, which is likely to cause poor fusion nuclei and lead to the fracture of the solder joint interface. Summary of the Utility Model

[0003] In view of the above problems, the purpose of the present utility model is to provide a flexible aluminum spot welding device for automobile door reinforcement plates that can improve production efficiency, production cost, and processing yield.

[0004] To achieve the above purpose, a flexible aluminum spot welding device for automobile door reinforcement plates provided by the present utility model is characterized in that it includes a fixture mounting rotating table, manipulators respectively arranged on both sides of the fixture mounting rotating table, and an aluminum welding gun arranged at the end of the manipulator.

[0005] The fixture mounting rotating table includes a gear seat, a driving motor arranged on the gear seat, a rotating table connected to the axis core of the gear seat on the gear seat, a partition plate arranged on the rotating table and horizontally divided into a front working area and a rear working area, a first workpiece fixture arranged on the rotating table in the front working area, a second workpiece fixture arranged on the rotating table in the rear working area, and auxiliary tooling structures arranged parallel to each other on the rotating table on both sides of the partition plate.

[0006] In some embodiments, the gear seat includes a base, a circular ring block arranged on the base, an annular internal gear rack arranged on the inner side of the circular ring block, and a driving gear connected to the driving motor arranged on the annular internal gear rack. The driving gear moves circumferentially along the annular internal gear rack under the drive of the driving motor.

[0007] In some embodiments, the auxiliary tooling structure includes fixed beams arranged parallel to each other on the rotating table on both sides of the partition plate, and third workpiece fixtures respectively arranged at both ends of the fixed beams.

[0008] In some embodiments, transparent viewing windows are respectively arranged on both sides of the partition plate.

[0009] The beneficial effects of the present utility model are to improve production efficiency, production cost, and the finished product rate of processing. Since after the improvement, aluminum spot welding is used to replace the SPR riveting and blind riveting processes for connecting aluminum plates, this aluminum spot welding station can also be used for steel spot welding, can independently weld different products, is applicable to a wider range of product welding, the system is stable and reliable, has good system rigidity and reliable operating accuracy, ensures the quality of parts, and achieves the effects of improving production efficiency, production cost, and the finished product rate of processing.

[0018] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] As Figure 1-8Shown is a flexible aluminum spot welding device for automotive door reinforcement plates, including a fixture mounting rotating table 01, manipulators 02 respectively arranged on both sides of the fixture mounting rotating table 01, and an aluminum welding torch 03 arranged at the end of the manipulator 02. In addition, a cooling circulation system of an electric control system component (including sensors, control panels, manual control buttons, programming instruments) is also equipped on one side of the manipulator 02. The fixture mounting rotating table 01 includes a gear seat 11, a driving motor 12 arranged on the gear seat 11, a rotating table 13 arranged on the gear seat 11 and connected to the axis core of the gear seat 11, a partition plate 14 arranged on the rotating table 13 and horizontally divided into a front working area and a rear working area, a first workpiece fixture 15 arranged on the rotating table 13 in the front working area, a second workpiece fixture arranged on the rotating table 13 in the rear working area, and auxiliary tooling structures 16 arranged parallel to each other on the rotating table 13 on both sides of the partition plate 14. The purpose of arranging the partition plate 14 above is to prevent the sparks at the welding position from spraying outwards to the tooling position area, so the partition plate plays a role of separating the two parts. The gear seat 11 includes a base 111, an annular block 112 arranged on the base 111, an annular internal rack 113 arranged on the inner side of the annular block 112, and a driving gear 114 arranged on the annular internal rack 113 and connected to the driving motor 12. The driving gear 114 moves in a circular motion along the annular internal rack 113 under the drive of the driving motor 12. The auxiliary tooling structure 16 includes fixed beams 161 arranged parallel to each other on the rotating table 13 on both sides of the partition plate 14, and third workpiece fixtures 162 respectively arranged at both ends of the fixed beams 161. Transparent windows 141 are respectively arranged on both sides of the partition plate 14, and the function of this window is to ensure that the working state of the manipulator 02 can still be observed under the action of the partition plate.

[0020] Working principle: On the rotating table 13 in the front working area, the modular workpiece is manually placed on the rotating table 13, and then the workpiece is clamped and fixed by the first workpiece fixture 15. The rotating table 13 moves in a circular motion along the annular internal rack 113 under the drive of the driving motor 12, that is, the horizontal plane of the rotating table 13 flips at this time. The workpiece in the front working area is to be worked, and the manipulator 02 drives the aluminum welding torch 03 to weld; the rear working area becomes the loading station for the workpiece to be fixed. After completion, it rotates to the welding position and the manipulator 02 drives the aluminum welding torch 03 to start welding, and so on in a cycle.

[0021] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the invention.
