Abstract
Description
Technical Field
[0001] This utility model relates to the field of excavator stick detection technology, specifically a rapid detection device for multiple models of excavator sticks. Background Technology
[0002] In the structure of an excavator, the stick is a crucial component, connecting the boom and the bucket. Due to its large span, it is subjected to significant tensile and shear forces during operation, making it highly susceptible to tearing. Therefore, the stick requires extremely high machining precision; any defects in the sheet metal or machining dimensions can lead to tearing during use.
[0003] Due to the diversity of excavator models, the size and shape of the stick also vary, requiring the machining process to adapt to the needs of different models. During machining, the multiple machined holes on the stick, the hole wall thickness, the machining dimensions between holes, and the parallelism require high precision, but existing machining technologies often struggle to quickly detect these requirements. Insufficient machining precision can lead to interference problems during assembly, requiring rework of the stick. This not only reduces machining efficiency but may also affect the performance of the final product.
[0004] Traditional processing and inspection methods are inefficient, failing to guarantee product quality and efficient continuous production. Particularly during welding, welding deformation and residual stress can affect the shape and dimensions of structural components, leading to localized tearing and increasing the cost of deformation correction and machining. Furthermore, while existing boom processing equipment can position the boom assembly for welding, its versatility is low, making it unsuitable for processing different boom specifications and models, and hindering production operations. Additionally, the inability to rotate this equipment forces some boom welds to be welded using methods unfavorable to weld formation, such as vertical or overhead welding, increasing welding difficulty and reducing processing quality.
