The grinding device is composed of two completely mirror milling and grinding units, and the inverted type is arranged on the body of the milling mill, and the two grinding wheels rotate in the direction of "feeding" on the respective tracks and the train;
Support frame
The operation device supporting frame comprises a base, a cross beam connecting plate and the movable frame is about three parts, the main support of the working unit, because of the complexity of milling condition and stress state, each frame requires a high support rigidity and high vibration performance, therefore, in the material, all using Q345C type steel plate welding which, in the design, using finite element analysis method, in the process, combined with steel plate separation and gas protection welding method of MAG mosaic structure, guarantee the stress characteristics of the supporting frame body to meet the requirements.
Beam base
The base of the cross beam is a matrix connected with the milling machine and the train carriage, and the rigidity and the anti vibration performance of the base are the basis of the milling and grinding. The beam is the base frame structure, the first internal rib plate welded frame, the construction sequence from the inside and external welding connection plate, separation structure and protection of MAG mosaic method combining with steel plate welding. The structure of the left and right moving frame is complex, the shape is strange, the processing precision is high, more than and 10 sets of tooling and fixture are designed in the welding and processing.
Cross connecting plate
The cross connecting plate is the supporting seat of the milling and grinding spindle unit for longitudinal and transverse movement.
Static analysis of left and right moving frame
rack truck
The moving frame is the supporting seat of the milling spindle system, and it also bears the impact load in the milling process directly.
