Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0013] Example 1 like Figures 1 to 4 As shown, an automotive door panel welding machine has undergone a series of design improvements on the original structure. This welding machine not only enables rapid welding of automotive door panel frame structures, but also improves welding efficiency and quality. The improved welding machine includes a welding robotic arm structure 1 (an existing robotic arm structure, which need not be further described). A welding mechanism is mounted on the welding robotic arm structure 1. The welding mechanism includes a first electric welding head 2 and a second electric welding head 3. One end of the first electric welding head 2 is mounted on an electric rotating platform 4 for rotating the first electric welding head 2. The other end of the electric rotating platform 4 is mounted on a movable structure, which drives the electric rotating platform 4 to move. One end of the second electric welding head 3 is mounted on an adjusting structure, which drives the second electric welding head 4 to move. The adjusting structure is connected to the electric rotating platform 4, which in turn drives the adjusting structure to rotate.
[0014] In this embodiment, the electric rotary table 4 is controlled to drive the first welding head 2 and the second welding head 3 to rotate. Then, the first welding head 2 and the second welding head 3 are controlled to weld the areas of the automotive door panel frame structure that require welding. Furthermore, to address areas that are difficult to weld, the welding robotic arm structure 1 and its adjustment mechanism are adjusted to control the rotation angle of the second welding head 3, allowing for welding (re-welding) in these areas, thereby improving welding efficiency and quality.
[0015] Example 2 Based on Embodiment 1, the movable structure includes a movable cylinder 5. The output rod of the movable cylinder 5 is connected to the electric rotary table 4, and the movable cylinder 5 drives the electric rotary table 4 to extend and retract. The housing of the movable cylinder 5 is slidably mounted on one end face of the connecting plate 6, which is used to connect with the welding robotic arm structure 1. Simultaneously, an electric slide rail is provided on the end face of the housing of the movable cylinder 5 near the connecting plate 6, and the housing of the movable cylinder 5 is slidably mounted on one end face of the connecting plate 6 via the electric slide rail.
[0016] In this embodiment, the welding robotic arm structure 1 is used to adjust and control the approximate distance between the first welding head 2 and the second welding head 3 and the automotive door panel frame structure. Further, the electric slide rail drives the movable cylinder 5 to "lift and slide" along the connecting plate 6, thereby adjusting the relative distance (specific and accurate welding distance) between the first welding head 2 and the second welding head 3 and the automotive door panel frame structure to be welded. Then, welding is performed by controlling and adjusting the first welding head 2 and the second welding head 3. If it is necessary to "re-weld" areas that are not properly welded, the second welding head 3 is adjusted and controlled to perform this process.
[0017] Example 3 Furthermore, the adjustment structure includes a movable adjustment block 31, with one end of the second electric welding head 3 passing through and connected to the movable adjustment block 31 by bolts. The movable adjustment block 31 is connected to one end of the movable curved block 32 via a rotary cylinder, which drives the movable adjustment block 32 to rotate. Additionally, the end of the movable curved block 32 furthest from the movable adjustment block 32 is connected to the output end of the hydraulic push rod 33. The housing of the hydraulic push rod 33 is connected to the electric rotary table 4 by bolts, which drives the hydraulic push rod 33 to rotate.
[0018] In this embodiment, the angle and position of the second welding head 3 are further adjusted and controlled by controlling the hydraulic push rod 33 and the rotary cylinder, so as to facilitate the "re-welding" of some positions that have not been welded in place; thereby improving the quality and efficiency of welding.
[0019] Example 4 The welding robotic arm structure 1 is mounted on a supporting electric rotary table 11, which drives the robotic arm structure 1 to rotate. A support base 12 is connected to the bottom of the supporting electric rotary table 11, and the supporting electric rotary table 11 is fixed to the ground via the support base 12. By using the support base 12 to install and fix the welding robotic arm structure 1 in the designated position, and then controlling and adjusting the rotation direction of the supporting electric rotary table 11 to drive the welding robotic arm structure 1, the welding of the automotive door panel frame structure can be maximized, reducing movement and handling, and achieving the goal of saving time and costs.
