Abstract

The invention relates to a high-precision milling machining method for a hob of a hard alloy granulator. The high-precision milling machining method comprises the following steps that a grinding knife with a required size is selected; two positioning plates are mounted on a milling table, a distance adjusting mechanism for adjusting the distance between the two positioning plates is arranged on the milling table, and locking mechanisms are mounted on the side walls of the positioning plates; the distance between the two positioning plates is adjusted through the distance adjusting mechanism, and the hob is fixed through the locking mechanisms; gear motors are mounted on the side walls of the positioning plates, and the locking mechanisms are driven by the gear motors to rotate, so that a to-be-milled blade on the hob is aligned with the grinding knife; a base used for bearing the milling table is arranged below the milling table, a lifting mechanism is arranged on the base, and the lifting mechanism is used for driving the grinding knife to move downwards; a sliding mechanism for driving the milling table to slide is arranged on the base, the sliding mechanism is used for driving the milling table to slide in the axial direction of the hob, and the hob is milled through the grinding knife. The angle of the hob is not required to be manually adjusted, time and labor are saved, and the milling efficiency is improved.

Description

technical field [0001] The present application relates to the field of hob milling of granulator, in particular to a high-precision milling method of tungsten carbide granulator hob. Background technique [0002] The hob of the granulator is a rotating hob with a blade. The hob is equivalent to a helical gear with a large helix angle. The number of teeth is the number of heads of the hob. For helical gears, the blade is prone to wear and passivation after long-term use. After the blade is passivated, the hob needs to be milled and polished. [0003] Notification number is that the Chinese patent of CN207171036U discloses a kind of semi-automatic milling machine, comprises milling machine frame, milling machine workbench and the milling machine tool that is arranged on the milling machine workbench, is provided with cleaning part and clamping device on the milling machine workbench; Cleaning part includes setting The storage box on the milling machine workbench and the magne...
