Four-spindle drilling machine for wearing plate on bogie side frame

Abstract

The invention discloses a four-spindle drilling machine for a wearing plate on a bogie side frame. The four-spindle drilling machine comprises a longitudinal mechanical sliding table, a transverse mechanical sliding table, four drilling power heads and a power box, the power box drives the four drilling power heads to rotate, the power box can be longitudinally movably installed on the longitudinal mechanical sliding table, the longitudinal mechanical sliding table can be transversely movably installed on the transverse mechanical sliding table, two main spindles are installed in the power box, one drilling power head is sleeved at two ends of each main spindle respectively, and the four drilling power heads are symmetrically arranged on two sides of the power box. According to the four-spindle drilling machine for the wearing plate on the bogie side frame, the position accuracy and forming efficiency of wearing plate mounting holes are guaranteed, the interchangeability of replacing and installing the wearing plate can be achieved, and the production circle is reduced.

Description

technical field [0001] The invention relates to a four-axis drilling machine used for wear plates on bogie side frames, and belongs to the technical field of mechanical equipment. Background technique [0002] At present, the bogie side frame is one of the most used and most critical parts in railway vehicle equipment. Facing the development trend of high-speed and heavy-duty railway freight, the design and manufacturing process of the key part side frame in the bogie assembly are put forward. To meet more stringent requirements, anti-vibration is one of the key functions of the bogie, which is mainly through the friction of the wedge and the wear plate, and the joint action of the shock-absorbing spring group. The wear plate is installed on the side frame, and it is used as a wearing part, which needs to be replaced when worn to a certain extent. At present, the wear plate is made into a standard part, and it is replaced in time according to the wear condition of the wear ...
