Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a robotic welding fixture for automotive side panels. Background Technology

[0002] Automotive side panel robotic welding fixtures are tools used in the automotive manufacturing process, especially in the body welding stage, to help robots accurately and stably fix and position automotive side panel components (including door and window frames). They improve production efficiency, ensure welding accuracy, and reduce human intervention through automated equipment.

[0003] In automobile manufacturing, there are many types of vehicle parts, including side panels. When using robots to weld side panels, they usually need to be clamped and fixed to ensure that the side panels do not wobble or misalign during the welding process. However, existing welding fixtures are usually designed with fixed positions, while side panels have different shapes, and different side panels may require different fixing points. This limits the range of use of the fixtures and makes adjustment difficult. Utility Model Content

[0025] A connecting plate 13 is fixedly connected to one side of the fixed plate 11. The connecting plate 13 facilitates the installation of the arc-shaped plate 14 and provides convenient support for the bottom of the side panel. The top of the connecting plate 13 is hinged to the arc-shaped plate 14 for fitting the bottom of the side panel. A movable plate 17 is installed inside the support shell 16. The movable plate 17 facilitates the adjustment of the height of the support plate 18 and provides convenient support for both sides of the bottom of the side panel.

The extension plate 8 is inserted with pins 25 that are used in conjunction with the slots 24.

[0028] Working principle: First, the side panel to be welded can be placed on top of the two support plates 18, and the first hydraulic rod 1201 is opened and retracted simultaneously. At this time, the fixing plate 1203 will cause the rotating ring 1204 to drive the fixing frame 1205 and the sliding frame 1206 around the support rod 1202 as the central axis, so that the clamping plate 1207 is lowered to clamp the side panel. Then, the arc plate 14 at the top of the extension plate 8 is used to fit against the bottom of the side panel for clamping. Subsequently, the extension and retraction of the first cylinder 20 can drive the clamping plate 21 to move up and down, and at the same time, the second cylinder 22 can drive the pressure plate 23 to move up and down to clamp and fix the car side panel, thus facilitating the robot to perform welding work. Before use, the user can adjust the position of the base 5 by loosening the screws on the top of the base 5, so as to adjust the clamp according to the side panel, ensuring welding stability and reducing usage limitations.
