Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a tapping machine used for machining large washers of bearing seats. Background Art

[0002] At present, the large washer of the bearing seat is an important mechanical component used to support and fix the bearing. Its performance and precision directly affect the stability and reliability of mechanical equipment. In the production and manufacturing process of the bearing seat, the large washer is one of its key supporting structures, and high precision and stability requirements are required. In order to meet these requirements, the large washer needs to be precisely processed and surface treated.

[0003] A tapping machine and an automatic tapping machine are disclosed in the Chinese utility model patent application disclosure CN 207577594 U. The device can change the feeding direction of the tap through the tap rotating assembly so that the tap can rotate in a plane. The existing tapping machine can only feed the tap in a plane perpendicular to the worktable and can only process the internal thread of the hole whose axis is perpendicular to the processing plane. If a hole whose axis is at a certain angle to the processing plane is to be processed, it is usually necessary to first process a plane perpendicular to the axis on the surface of the workpiece, and then use this plane to process the internal screw hole.
