The long arm excavator is based on the ordinary excavator, and the change on the appearance is from the length of the excavator boom. In fact, it can make the whole machine more stable and reliable in operation. And there is also a great change in the control mode and the structure. In order to get a better understanding of the excavator and the long arm.
In mechanical production, the machining accuracy control of large structural parts is always a technical problem. The super long arm has large dimension and high machining accuracy, so the quality problem of ultra long arm machining is the primary problem for the production of ultra long arm excavators.
1. Processing technical analysis
The ultra long arm is a slender structure with complex structure, large size and large quality. It is required to be machined after welding. The ultra long arm machine needs machining plane, hole and threaded hole when machining. It has many contents, complex structure, high accuracy of stealing processing, and for such large quality slender structure, it has low rigidity and easy to produce deformation and vibration when machining.
2. Selection of processing equipment
Machining equipment includes not only machine tools, cutting tools and measuring tools, but also special machine fixtures. The selection of machine tools and the design of the machine jig are directly related to the processing quality and production efficiency of the super long arm.
