Processing method of end cover of motor

Abstract

The invention discloses a processing method of an end cover of a motor and belongs to the technical field of machine manufacture. The processing method uses an end-cover milling clamp. The processing method comprises the following steps: (A) installing the clamp, namely installing the clamp on a working platform of a milling machine; (B) installing a workpiece, namely enabling an opening of the end cover to be downward, enabling connecting pin holes 94 of an end-cover connecting plate 91 to correspond to thread holes in a workpiece positioning plate 22, tightening fastening screws 10 in the two holes, pressing and positioning the end-cover connecting plate 91 on the workpiece positioning plate 22, and respectively arranging workpiece clamping claws 1 on the outer wall of the end cover; (C) starting the milling machine, enabling pressurized gas to be inputted from a gas inlet a, enabling the clamping claws to clamp the end cover, firstly adopting a vertical milling cutter to carry out hole-milling processing on shaft holes of the end cover, and then milling the end surface of a baseplate of the end cover; and (D) stopping a boring machine, enabling the pressure to be eliminated, loosening the clamping claws and taking out the end cover. The processing method disclosed by the invention has the advantage that the problems that an existing end cover processing is complex in clamping and low in production efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a fixture for end cover processing. Background technique [0002] The end cover is a cover installed at both ends of the motor and other equipment casings, such as figure 1 , figure 2 The shown end cap 9 includes a cover body 91 with a circular opening and a chassis 92, the open end of the cover body 91 stretches out a connecting plate 95 transversely to the cover body 91, and the chassis 92 is provided with a coaxial opening with the circular opening. Shaft holes 93, four connecting pin holes 94 are opened on the connecting plate; among them, the shaft holes 93 are used to wear the output shaft of the motor, which plays a role in determining the spatial position of the rotor shaft, and the machining accuracy of the outer end surface and the shaft hole The requirements are relatively high. At present, the processing of the shaft hole 93 of the end cover is pos...
