[0004] The applicant discovered during the use of the aforementioned welding device that the welding table of the device was not equipped with a quick positioning structure for the welded parts, which required a long time to align and match the two welded parts, resulting in low processing efficiency during mass production. Utility Model Content

[0005] The purpose of this utility model is to provide an installation and positioning mechanism for welding automotive door panel armrests, aiming to solve the problem that existing welding devices do not have a quick positioning structure for welded parts, thus requiring a long time to align and match the two welded parts, resulting in low processing efficiency during mass production.

[0006] To achieve the above objectives, this utility model provides an installation and positioning mechanism for welding automotive door panel armrests, including a base and a welding table, wherein the welding table is fixed on the base, and a guide device is also included.

[0007] The welding platform is provided with a first placement part and a second placement part. The first placement part has a first limiting protrusion on its rear side, which can abut against the rear side of the welding part on the left. The second placement part is integrally connected to the first placement part and is located on the right side of the first placement part. The second placement part has a second limiting protrusion on its rear side, which can abut against the rear side of the welding part on the right.

[0008] The guiding device includes rotating columns and clamping components. Several rotating columns are rotatably connected to the welding table and slidably connected to the left end face of the welding piece on the left side. The clamping components are positioned above the welding piece on the left side.

[0009] The second placement part is also provided with a limiting plate at the top, which slides with the right top end of the welded part on the right side.

[0010] The clamping assembly includes a clamping plate and an actuating component.

[0013] This utility model discloses an installation and positioning mechanism for welding automotive door panel armrests. During processing, a welding component is first placed on a first placement part, with its left side in contact with a rotating column. Then, while maintaining sliding contact, it is pushed until its rear side abuts against the first limiting protrusion for rapid positioning. Next, another welding component is placed directly on a second placement part and pushed backward. During pushing, it can directly align the weld seam with the previously placed welding component. Finally, when the rear side of the welding component on the second placement part abuts against the second limiting protrusion, rapid mating and docking between the welding components can be achieved. Further control of the clamping assembly to clamp the welding component on the left side allows for welding. This solves the problem that existing welding devices do not have a rapid positioning structure for welding components, thus requiring a long time for alignment and docking between two welding components, resulting in low processing efficiency during mass production.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the installation and positioning mechanism for welding automotive door panel armrests. Figure 2 This is a structural schematic diagram of the welding table 102. This utility model provides an installation and positioning mechanism for welding automotive door panel armrests: it includes a base 101, a welding table 102, and a guiding device. The welding table 102 is provided with a first placement part 103 and a second placement part 104. The first placement part 103 has a first limiting protrusion 105 on its rear side, and the second placement part 104 has a second limiting protrusion 106 on its rear side. The guiding device includes a rotating column 107 and a clamping assembly. The clamping assembly includes a clamping plate 109 and an actuating component. The actuating component includes a bracket 110, a cylinder 111, and a guiding component 112. This solution solves the problem that existing welding devices lack a rapid positioning structure for welded parts, requiring lengthy alignment and fitting between two welded parts, resulting in low processing efficiency during mass production. It is understood that the aforementioned solution enables rapid docking of automotive door panel armrest welded parts, thus improving welding processing efficiency.

[0022] In this embodiment, the welding station 102 is fixed on the base 101, and the base 101 can be fixed by bolts, and the welding station 102 is fixed by bolts.

[0023] The welding table 102 is provided with a first placement part 103 and a second placement part 104. The first placement part 103 has a first limiting protrusion 105 on its rear side, which can abut against the rear side of the welding part on the left. The second placement part 104 is integrally connected to the first placement part 103 and is located on the right side of the first placement part 103. The second placement part 104 has a second limiting protrusion 106 on its rear side, which can abut against the rear side of the welding part on the right. The first placement part 103 and the second placement part 104 are used for placing and supporting the welding parts. The second placement part 104 is an arc-shaped area on the right side of the first placement part 103. The first limiting protrusion 105 and the second limiting protrusion 106 can abut against the rear side of the welding parts placed on the left and right for limiting.

[0024] Several rotating columns 107 are rotatably connected to the welding table 102 and slidably connected to the left end face of the welding component on the left side. The clamping assembly is positioned above the welding component on the left side. The stepped mounting shaft at the bottom of the rotating column 107 is mounted on the welding table 102 via a rotating bearing. A retaining ring hole is provided in the bearing mounting hole of the welding table 102, and a retaining ring is installed in the retaining ring hole for limiting the outer ring of the bearing. A retaining ring groove is provided at the bottom of the rotating column 107, and a retaining ring is installed in the retaining ring groove. After installation, the retaining ring abuts against the inner ring of the rotating bearing. The clamping assembly is used to fix the welding component placed on the left side.

[0025] Secondly, a limiting plate 108 is also provided on the top of the second placement part 104, and the limiting plate 108 slides in cooperation with the top right end of the welded part on the right side. The limiting plate 108 is integrally formed with the second placement part 104 and is used to limit the top right end of the welded part on the right side. When the welded part on the right side is placed and pushed, its top right end must be kept in sliding contact with the limiting plate 108.

[0026] Then, a rubber pad is provided at the bottom of the clamping plate 109, which can abut against the top of the weldment on the left side; the actuating component is provided on the side of the welding table 102 near the clamping plate 109. The rubber pad at the bottom of the clamping plate 109 prevents damage to the surface of the weldment when clamping, and the actuating component is used to drive the clamping plate 109 to move vertically.

[0027] Finally, the bracket 110 is welded to the welding table 102 and located on the left rear side of the welding table 102; the cylinder 111 is fixed to the top of the bracket 110, and its output end is connected to the clamping plate 109; the guide component 112 is disposed on the side of the bracket 110 near the clamping plate 109. The bracket 110 is L-shaped, with its bottom end welded to the welding table 102, and the top is fixed to the cylinder 111 by bolts. The output end of the cylinder 111 is connected to the clamping plate 109 by bolts. The working pressure of the cylinder 111 is regulated by an oil-water separator on the air supply line or by a pressure regulating valve. The guide component 112 includes a T-shaped sliding sleeve and a guide rod. The T-shaped sliding sleeve is fixed to the bracket 110 by bolts, and the bottom threaded end of the guide rod is installed in the threaded hole at the top of the clamping plate 109. The optical axis end slides linearly with the T-shaped sliding sleeve.

[0028] When using this utility model to solve the problem that existing welding devices lack a rapid positioning structure for welded parts, requiring a long time for alignment and matching between two welded parts, resulting in low processing efficiency during mass production, the process involves first placing one welded part on the first placement part 103, ensuring its left side contacts the rotating column 107. Then, while maintaining sliding contact with the rotating column 107, it is pushed until its rear side abuts against the first limiting protrusion 105 for rapid positioning. Next, the other welded part is directly placed on the second placement part 104 and pushed backward. During this pushing, it can directly align with the previously placed welded part for weld seam alignment. During alignment, the left welded part can be flipped upward while maintaining contact with the rotating column 107 on its left side, facilitating the leftward rotation of the right welded part. The side end is located below the right end of the left welding part. At the same time, when the right welding part is placed and pushed, its right top end must be kept in sliding contact with the limiting plate 108. Finally, when the rear side of the welding part on the second placement part 104 abuts against the second limiting protrusion 106, the welding parts can be quickly fitted and connected. If the left welding part is flipped, it can be pushed to the side. Finally, the cylinder 111 is controlled to move, pushing the clamping plate 109 down and abutting against the top of the left welding part, thereby clamping the left welding part and welding can be performed. This solves the problem that the existing welding device does not have a quick positioning structure for welding parts, which requires a long time to align and fit the two welding parts, resulting in low processing efficiency when mass-producing products.

[0029] Example 2:

[0030] like Figure 3 As shown, where Figure 3This is a schematic diagram of the overall structure of the installation and positioning mechanism for welding automotive door panel armrests. Based on the first embodiment, this utility model provides an installation and positioning mechanism for welding automotive door panel armrests. The actuating component further includes a stabilizing frame 201, which is detachably connected to the welding table 102 and the bracket 110, and is located on the side of the welding table 102 near the bracket 110. The stabilizing frame 201 has rectangular connecting plate ends on both sides. One side is connected to the horizontal section of the bracket 110 by bolts, and the other side is connected to the welding table 102 by bolts.

[0031] In this embodiment, the working stability of the support 110 can be improved by setting the stabilizer 201.
