Abstract
A right-angle milling head device comprises a shell, and the right-angle milling head device is characterized in that a transmission mechanism is connected with a milling head main shaft sleeve so as to drive the milling head main shaft sleeve to rotate, two opposite sides of the milling head main shaft sleeve are respectively provided with a supporting base, and two ends of a tool are respectively connected with the milling head main shaft sleeve and the supporting bases. The supporting base is provided with a follow-up shaft sleeve which is supported by a bearing so as to rotate along the tool which is installed on the supporting base. Through the structure, i.e. the supporting bases, the stress situation of the tool is greatly improved, and technical problems in the prior art that the machining precision is reduced due to unreliability of the stress of a cantilever structure when a deep hole is machined can be solved. The tool is strained in two directions, so that the rigidness is improved, and the deep hole machining precision is further guaranteed. The supporting base can be adjusted in a sliding way along the axis of the tool so as to be adjusted according to the depth of a machined hole. Due to adopting the right-angle milling head device, mechanical machining of a high-precision specially-shaped deep hole and especially of a non-circular hole such as a square hole and a triangular hole can be realized, and the technical bottleneck for mechanically machining the specially-shaped hole can be broken through.
