Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile production line technology, and in particular to an auxiliary device for repairing skids in an automobile painting production line. Background Technology
[0002] The existing heavy-duty skids in automotive painting production lines have the following problems during long-term transport operation: 1. Due to variations in workpiece weight, length, and shape, the bottom of the skids exhibits pitting deformation (measured deformation of 8-10mm), causing severe swaying during operation. 2. The outermost edge of the skid's mechanical support arm suffers severe deflection deformation (measured 4-6mm), leading to workpiece skew. 3. The leveling pad at the bottom of the skid has detached from the weld, causing the skid to jam.
[0003] To address these issues, the common practice is to lift the skid to the ground for repair. However, this technique still has the following problems: the deformed parts at the bottom cannot be repaired, and the skid cannot be secured, posing a risk of tipping over and injuring people during the repair process; due to the large maximum deviation in ground elevation (measured at 20-30mm), there is no repair benchmark, which significantly affects the quality of skid inspection, repair, and welding.
