Description

Technical Field

[0001] This utility model relates to the field of support and clamping device technology, specifically a device for machining excavator booms. Background Technology

[0002] An excavator is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and loads them into transport vehicles or unloads them at a stockpile. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of excavators in the construction machinery industry has been relatively rapid, and they have become one of the most important pieces of construction machinery. During the production process, the excavator's boom is often machined. Due to the variety of excavator models and the lack of dedicated machining equipment, workers typically clamp the workpiece to a suitable position on a workbench before machining it. This reduces auxiliary machining time. The process is lengthy, labor-intensive, and inconvenient for workers. Existing solutions, such as the excavator boom machining fixture disclosed in patent CN201811472263.7, which uses a side-clamping device to fix the boom, have drawbacks. They can only clamp two different booms, limiting applicability and failing to address the need for multiple machining fixtures due to the variety of excavator models. Furthermore, this device lacks bottom support for the boom, leading to unstable support during machining, excessive vibration, and ultimately, a decline in product quality. Utility Model Content
