The utility model provides a slewing bearing deep hole processing device for a through hole with the length-diameter ratio thereof greater than seven, wherein the processing method is modified and auxiliary equipment is additionally provided. Due to the adoption of the device, after one side of the through hole is drilled and positioned through a positioning pin, the other side of the through hole is docked and drilled. Therefore, the length-diameter ratio of a drill bit is reduced and the rigidity of the drill bit is improved. Meanwhile, during the processing procedure, chips are smoothly removed and the drill bit is not easily broken. Processed hole walls are good in smoothness and the diameters of processed holes are unified. The work efficiency and the precision of a numerical control high-speed drill are fully improved. The quality of products is ensured and the production efficiency is increased. The slewing bearing deep hole processing device comprises a workpiece, a positioning pin, a backing plate, a first compression bolt, a first compression nut, a second compression bolt, a second compression nut, a pressing plate and a support. The backing plate is arranged on the workbench of a machine tool. A circular ring-shaped workpiece is arranged on the backing plate. The workpiece and the backing plate are equipped with prepared holes correspondingly. The positioning pin is arranged inside the prepared holes. The slewing bearing deep hole processing device is simple in structure and convenient in operation. Due to the adoption of the device, the butt joint of deep holes can be easily realized and the requirement of the position accuracy of the holes is satisfied. The slewing bearing deep hole processing device is scientific, efficient, accurate and practicable.read more
