Abstract
The utility model provides a device for machining of a diesel engine cylinder cover camshaft hole. The device comprises a plurality of boring bars with different machining depths. When the device is used for boring of a camshaft hole, the boring bar with the smallest machining depth is utilized first for boring of a part of the camshaft hole, and then the remaining boring bars are utilized sequentially from a shorter one to a longer one according to the different machining depths of the boring bars. After that, a bored hole is used as a support for boring of the remaining parts of the camshaft hole till the machining of the whole camshaft hole is completed. Due to the fact that the machined hole is utilized as the support, the longer boring bar penetrate through the machined hole first and then carry out boring, and therefore shaking of the longer boring bar in the hole boring process is alleviated, use of a boring die is avoided, and investment cost of equipment is further reduced.
