[0002] During the welding process of the shock absorber of new energy vehicles, the end of a cylindrical workpiece is welded to a cap. The first choice is to cover the cap on the end of the cylindrical workpiece, and then clamp it into the weld through a clamping device (manipulator). The traditional method is to adjust the angle of the welding gun, and then aim the muzzle of the welding gun at the gap between the cap and the cylindrical workpiece. After that, the turntable for placing the cylindrical workpiece in the welding machine rotates, and the welding gun continuously spits out molten welding wire to the gap between the cap and the cylindrical workpiece, thereby welding the cylindrical workpiece and the cap together.

The second is that there is a lot of welding slag. For this reason, it is necessary to design a welding machine that can detect the weld, fix the cap during welding, and produce less welding slag.

[0028] like Figure 1-8 As shown, a multi-station seam welding machine for shock absorbers of new energy vehicles includes a workbench 1 and a bracket 2. The bracket 2 is fixedly arranged on the back of the workbench 1, and the upper end of the bracket 2 is higher than the upper surface of the workbench 1. A product conveying device and a first manipulator 3 are fixedly arranged on the left side of the workbench 1, and a weld detection device and a second manipulator 4 are arranged on the right side of the workbench 1. A rotating disk 5 is provided on the workbench 1, and at least three product placement jigs 6 are evenly arranged on the rotating disk 5 around its center. A welding pad 7 cooperating with the rotating disk 5 is provided on the bracket 2 through a first lifting device 41, and a pressure rod 9 cooperating with the welding pad 7 is vertically provided on the execution end of the first lifting device 41 at a distance from the welding pad 7 through a second lifting device 8. The output end of the product conveying device and the left half of the workbench 1 are both within the travel range of the first manipulator 3, and the input end of the weld detection device and the right half of the workbench 1 are both within the travel range of the second manipulator 4.

[0029] In this embodiment, when in use, the product conveying device conveys the cylindrical workpiece covered with the cap to the travel range of the first manipulator 3, and the first manipulator 3 clamps the cylindrical workpiece covered with the cap to the product placement fixture 6 on the workbench 1. After that, the second lifting device 8 descends so that the pressure rod 9 presses the upper cap of the cylindrical workpiece to achieve restriction of the cylindrical workpiece and the cap. At the same time, the circumferential surface of the welding pad 7 contacts the connection between the cap and the cylindrical workpiece and the welding pad 7 rotates, so that the cap and the cylindrical workpiece are welded together. After welding, the pressure rod 9 and the welding plate 7 rise and leave the cylindrical workpiece and the cap. Then, the rotating disk 5 rotates, so that the product placement fixture 6 on which the welded cylindrical workpiece is placed rotates to the travel range of the second manipulator 4. The second manipulator 4 clamps the welded cylindrical workpiece from the product placement fixture 6 to the weld detection device. The weld detection device detects the weld to determine whether the welding is qualified. This makes it easier for workers to classify the welded products later. Of course, there can also be a control system. The control system controls the second manipulator 4 to clamp the cylindrical workpiece after the weld inspection according to the detection results of the weld inspection device, so that the second manipulator 4 clamps the qualified cylindrical workpiece to the designated area and clamps the unqualified cylindrical workpiece to the area for placing unqualified products (cylindrical workpieces after weld inspection). At the same time, the method of welding the cylindrical workpiece with a welding plate has relatively less welding slag.

[0030] As a preferred embodiment, the execution end of the first lifting device 41 is fixedly provided with a first linear drive mechanism 10, the driving direction of the first linear drive mechanism 10 is parallel to the conveying direction of the product conveying device, the execution end of the first linear drive mechanism 10 is provided with a mounting seat 11, the lower surface of the mounting seat 11 is rotatably provided with the welding pad 7, the projection of the welding pad 7 on the workbench 1 intersects with the projection of the rotating disk 5 on the workbench 1, the end face of the welding pad 7 is parallel to the workbench 1, and the welding pad 7 is electrically connected to the power supply on the bracket 2. After such an arrangement, the coordinated arrangement of the first linear drive mechanism 10 and the first lifting device 41 facilitates adjustment of the position of the welding pad 7, wherein the first linear drive mechanism 10 can be provided in many ways, such as a linear motor, a cylinder, etc., which can all achieve the function of linear drive, and this application again does not impose any restrictions.

The driving direction of the second linear drive mechanism 13 is parallel to the end surface of the welding pad 7 and toward the circumferential surface of the welding pad 7. Thus, by providing the second linear drive mechanism 13 to control the trimmer 14, the welding pad 7 is corrected, which facilitates welding of cylindrical workpieces. Similarly, the second linear drive mechanism 13 can also be any device capable of driving the trimmer 14 to achieve linear movement, such as a linear motor or a cylinder.

[0032] As a preferred embodiment, the execution end of the first lifting device 41 is also provided with a pad corrector. The pad corrector is used to correct the position of the pad 7 relative to the cylindrical workpiece to be welded placed on the product placement fixture 6.

[0033] As a preferred embodiment, the pad corrector includes a third mounting platform 15, a cylinder 16, a correction disk 17, a drive motor 18, and a power transmission mechanism. The third mounting platform 15 is rotatably provided on the second mounting platform 12. The rotation axis of the third mounting platform 15 is parallel to the rotation axis of the pad 7. The second mounting platform 12 is rotatably provided with a cylinder 16. The cylinder 16 is parallel to the end face of the pad 7. The execution end of the piston rod of the cylinder 16 is rotatably connected to the third mounting platform 15. The third mounting platform 15 is rotatably provided with a cylinder 16.

A rotating shaft 20 is provided, and the rotating shaft 20 is parallel to the rotation axis of the welding pad 7. The lower end of the rotating shaft 20 is coaxially fixed with the correction disk 17, and the end surface of the correction disk 17 is parallel to the end surface of the welding pad 7. The upper end of the rotating shaft 20 is connected to the output end of the reducer through the power transmission mechanism, and the input end of the reducer is connected to the output end of the drive motor 18. The drive motor 18 is fixed to the execution end of the first lifting device 41 and is located above the correction disk 17. With this arrangement, the cylinder 16 can drive the third mounting platform 15 to rotate relative to the second mounting platform 12, and at the same time, adjust the positional relationship between the correction disk 17 and the welding pad 7.

[0034] As a preferred embodiment, the power transmission mechanism includes a transmission rod 21, a first notch 22 is provided on the output end surface of the output shaft of the reducer, and both ends of the first notch 22 extend to the outside of the output shaft of the reducer, a second notch 23 is provided on the upper end surface of the transmission rod 21, and a third notch 24 is provided on the lower end surface of the transmission rod 21, and both ends of the second notch 23 and the third notch 24 extend to the outside of the transmission rod 21, a fourth notch 25 is provided on the upper end of the rotating shaft 20, and both ends of the fourth notch 25 extend to the outside of the rotating shaft 20, a first rotating block 26 is provided in the first notch 22, and a first rotating axis 27 and a second rotating axis 28 are provided on the first rotating block 26, and the first rotating axis 27 is perpendicular to The second rotating shaft 28, the axis of the first rotating shaft 27 and the axis of the second rotating shaft 28 are coplanar, the ends of the first rotating shaft 27 are rotatably connected to the side walls of the first notch 22, and the ends of the second rotating shaft 28 are rotatably connected to the side walls of the second notch 23.

The ends of the third rotating shaft 42 are rotatably connected to the side walls of the third notch 24, and the ends of the fourth rotating shaft 43 are rotatably connected to the side walls of the fourth notch 25. With this arrangement, since the transmission rod 21 can achieve radial rotation relative to the output shaft of the reducer without affecting the axial rotation driven by the output shaft of the reducer, the design does not need to be affected by the coaxiality of the transmission rod 21 relative to the output shaft of the reducer.

[0035] As a preferred embodiment, the second lifting device 8 is provided on the actuating end of the first lifting device 41, and is positioned above the soldering pad 7.

The two fingers of the finger cylinder 35 are separated on both sides of the cross bar 33, and the free ends of the fingers of the finger cylinder 35 are higher than the upper surface of the cross bar 33. The width of the cross bar 33 is less than or equal to the diameter of the positioning column 34. After this arrangement, when conveying the cylindrical workpiece, the lower end of the cylindrical workpiece is directly inserted into the positioning column 34 (coaxial with the positioning column 34). At the same time, the finger cylinder 35 clamps the cylindrical workpiece. Due to the provision of the support rod 44, the provision of the finger cylinder 35 will not affect the provision of the positioning column 34. In addition, due to the provision of the cross bar 33, it is convenient to provide the positioning column 34, so that the provision of the positioning column 34 will not affect the finger cylinder 35.

[0037] As a preferred embodiment, the weld inspection device includes a third lifting device 36, an inspection camera 37, a rotary motor 38, and a second pallet 39.
