Abstract

The invention provides an excavator rotary motor shell inclined disc face machining device and a machining method thereof.The excavator rotary motor shell inclined disc face machining device comprises a tool plate, a center hole is formed in the tool plate and used for containing a to-be-machined rotary motor shell, and a plurality of counter bores are formed in the circumferential direction of the center hole; the threaded holes correspond to the counter bores one to one, the threaded holes are formed in the sides, away from the center hole, of the counter bores, the pin holes are formed in the circumferential direction of the center hole, the ball sockets are formed in the sides, away from the center hole, of the pin holes, and the steel balls are arranged in the ball sockets; the plurality of pin holes and the plurality of counter bores are used for mounting the tool plate on a machining platform of a horizontal machining center; the steel balls are matched with the inclined disc face of the rotary motor shell to determine the machining position. The method solves the trouble of calculating the rotation center of the machine tool and the rotation center and the machining starting point during machining of the horizontal machining center, the machining efficiency is improved, and the machining difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing device and a processing method for a swash plate surface of an excavator slewing motor casing. Background technique [0002] At present, in the manufacture of various types of excavator slewing motor casings, it is necessary to process an inclined plane in its inner cavity. Since the inclined plane is located inside the shell, it is not easy to determine the starting point of machining when machining on a horizontal machining center. It is troublesome to calculate the position of the machining coordinates by relying on the turning center of the machine tool, which affects the machining efficiency and accuracy, and wastes time. Another waste of manpower. [0003] At present, in the manufacture of various types of excavator slewing motor casings, it is necessary to process an inclined plane in its inner cavity. Since the inclined plane is lo...
