Turning Technology of End Cover of Thin Wall Energy Saving Motor

Abstract

The invention belongs to the field of motor end cover production and manufacturing, and particularly relates to a lathe machining technology of a thin-wall energy-saving motor end cover. The lathe machining technology is characterized by comprising the following steps: (1) adopting a three-jaw or four-jaw chuck to clamp a blank piece, and carrying out rough turning on the blank piece; (2) drilling a bolt hole in a small end face; (3) carrying out finish turning on the small end face; (4) axially clamping and positioning the small end face after finish turning; (5) finally adopting a numerically controlled lathe electric circular cutter holder and a plurality of lathe tools for clamping at a time, and completing the finish turning of end faces, large seam allowances and inner holes. Screws are supported by accurately clamping the small end face and adopting the vibration reduction of an auxiliary rubber stopper, so that the turning clamping deformation can be prevented, the turning vibration of the thin-wall end cover is eliminated, and the problems of big turning clamping deformation generated when the thin-wall end cover is machined traditionally, vibration during turning, and the like are solved; the motor end cover manufactured and obtained by using the technology is high in precision, stable in quality and high in qualified rate, the abandonment rate and repair rate are avoided, the cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a turning process of a thin-walled energy-saving motor end cover, which belongs to the field of motor end cover production and manufacturing. Background technique [0002] The motor end cover is a kind of workpiece that is often processed in machining. It is installed at both ends of the motor shell. The middle hole of the motor end cover is installed with the bearing. The two small end faces are drilled to assemble the bearing gland. The assembly of the casing plays a supporting and guiding role for the motor shaft. The main dimensional accuracy and mutual position accuracy of the end cover are required to be high, especially the verticality of the end face, the coaxiality of the hole, and the cylindricity, which directly affect the operation of the motor. efficiency and energy saving. At present, in the field of motor end cover processing, the main processing method of the end cover is: after rough turning, use a three-jaw o...

Problems solved by technology

This processing method is only suitable for ordinary motor end caps with large wall thickness, but for the processing of thin-walled motor end caps, especially large and medium-sized thin-walled end caps, there are obvious disadvantages, mainly due to the large deformation of thin-walled end caps during turning and clamping. Due to the disadvantages of vibration and other shortcomings, the shape and position accuracy of end face verticality, hole coaxiality and cylindricity cannot be guaranteed after processing, and the processing quality requirements of thin-walled high-efficiency energy-saving motor end covers cannot be met.
