DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0031] Example 1

[0032] An automobile automated welding adjustment frame, such as Figure 1-Figure 8 As shown, it includes a control seat 1, a guide rail 3 is arranged on the right side of the control seat 1, a placement seat 2 is slidably arranged on the guide rail 3, the left part of the placement seat 2 is a trapezoidal structure, and a plurality of groups of ribs are arranged inside it, and also includes: a moving mechanism 4, the moving mechanism 4 is arranged on the placement seat 2, and the moving mechanism 4 is used to drive the parts to be welded to perform flexible position adjustment; a thermal compensation mechanism 5, the thermal compensation mechanism 5 is arranged on the upper part of the placement seat 2, and the thermal compensation mechanism 5 is used to prevent the welding point from overheating and deformation, and to perform cooling compensation.

[0033] It should be noted that when performing automated welding of automobile parts, the device can be used to assist in specific operations. First, the parts to be welded are placed on the mobile mechanism 4, and then the mobile mechanism 4 is used to drive the parts to adjust their positions to improve the flexibility of welding the parts. At the same time, during the welding process, the thermal compensation mechanism 5 is used to compensate for the temperature of the welding position to avoid deformation of the welding parts of the parts due to excessive temperature at the welding points.

[0034] The moving mechanism 4 includes a first driving motor 41. The first driving motor 41 is arranged at the bottom of the placement seat 2. The output shaft of the first driving motor 41 is arranged to face right. A first screw rod 42 is connected to the output shaft of the first driving motor 41. The first screw rod 42 is rotatably connected to the placement seat 2. A sliding seat 43 is slidably arranged on the placement seat 2. The sliding seat 43 is used to support the welding parts. The sliding seat 43 is threadedly connected to the first screw rod 42.

[0035] It should be noted that as the welding part is placed on the placement seat 2, the sliding seat 43 is in contact with the bottom of the component, and then the position of the component is adjusted according to the welding needs. At this time, it is only necessary to start the first drive motor 41. The rotation of the output shaft of the first drive motor 41 will drive the first screw 42 to rotate, so that the sliding seat 43 can be adjusted along the placement seat 2, driving the welding component to be flexibly adjusted in position, thereby improving the flexibility of the welding operation.

[0036] The thermal compensation mechanism 5 includes a mounting track 51, and the mounting track 51 is arranged on the upper right side of the placement seat 2 by bolts. A mechanical arm assembly 52 is slidably connected to the mounting track 51. A close-fitting part 53 is arranged on the right end of the mechanical arm assembly 52. ​​The close-fitting part 53 is used to contact and fit with the welding point of the component to be welded. A cooling assembly 54 is arranged on the right side of the mechanical arm assembly 52, and the cooling assembly 54 is connected to the close-fitting part 53.

[0037] It should be noted that during the component welding process, the control seat 1 is relied on to control and adjust the position of the robotic arm assembly 52, so that the robotic arm assembly 52 can slide along the mounting track 51, so that the robotic arm assembly 52 can be aligned with the welding point, and then the robotic arm assembly 52 is controlled to drive the end of the close-fitting part 53 to move, so that the close-fitting part 53 can fit with the welding point, and the cooling component 54 is started synchronously. The cooling component 54 will quickly cool down the close-fitting part 53, thereby performing thermal compensation on the welding point to avoid the welding point temperature being too high, which will cause deformation at the welding point of the two components.

[0040] It should be noted that after the component is placed, the rotating frame 61 is first adjusted according to the shape of the component so that the extended parts at the front and rear ends of the rotating frame 61 can correspond to the component, and then the output shaft of the second drive motor 62 is controlled to move, so that the rotating seat 63 can rotate at a corresponding angle, so that the extended part of the rotating frame 61 can fit the component, and then the second drive motor 62 is turned off and the servo motor 64 is started. The output shaft of the servo motor 64 drives the second screw 65 to rotate, so that the moving part 66 drives the sliding pad 67 to approach the component, and finally the position of the sliding pad 67 is adjusted by sliding, so that the sliding pads 67 can complete the adaptive clamping of the component, and relying on the characteristics of the sliding pad 67, the component is tightly clamped, so that the component can be more stable during the welding process.

[0041] It also includes a buffer cooling mechanism 7, which includes a control component 71. The control component 71 is arranged on the right side of the placement seat 2.

[0044] It should be noted that during the welding process, the position of the blowing assembly 82 is adjusted according to the rotation of the welding position, and then the blowing assembly 82 is started to blow away the debris that may be generated during the welding process to prevent the debris from splashing outward.

[0045] The utility model also includes a clamping mechanism 9, which includes a mounting groove 91. The mounting groove 91 is opened on the rotating disk. The mounting groove 91 is a cross-shaped structure. Two electric push rods 92 are slidably connected in the mounting groove 91.
