Embodiment Construction

[0018] Such as figure 1 The motor bracket holes shown are machined as follows:

[0019] Firstly, align the center of the machine tool table, and then process a datum plane on the same side of the left and right ends of the workpiece to be processed as the subsequent alignment datum. Facing the workbench of the machine tool with this datum surface, place the workpiece to be processed flat on the workbench, align and press it so that the axis of the workpiece is parallel to the workbench, the flange plane at the left end of the workpiece is perpendicular to the workbench, and the axial direction of the two bracket holes Parallel to the direction of the spindle of the machine tool, one of the bracket holes is adjacent to the spindle. After pressing the workpiece, take the center point of the worktable as the origin, and use coordinate translation to find the distance X from the flange plane of the workpiece to the origin (the center of the workbench). Since the left and right e...

Abstract

The invention discloses a processing method of bracket holes of a tunneller type asynchronous motor. The method comprises the following steps: a, finishing the processing of a left end surface and a right end surface of a work piece; b, processing a datum plane as a subsequent alignment datum; c, aligning the center of a machine working table; d, finding the distance (H-X) between the center line of the bracket holes C and D and an origin (the center of the machine working table) by taking the center of the machine working table as the origin; e, aligning the center of a bracket hole to be processed by utilizing coordinate translation and then processing; and f, revolving the machine working table 180 degrees by taking the origin as the center, aligning an unprocessed hole by utilizing coordinate translation, comparing with the distance when the first hole is aligned, the distances are equal and are both (H-X) but of opposite directions; after reverse alignment, ensuring a main shaft center of a boring machine to be coincident with the central axis of the hole to be processed, and then half-finish boring and finish boring another bracket hole. The method has the advantages: 1, increasing the production efficiency; 2, reducing the labor intensity of workers; and 3, saving the manufacturing cost.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a processing method for a bracket hole in an asynchronous motor of an excavation type. Background technique [0002] The structural characteristics of the two bracket holes C and D in the explosion-proof three-phase asynchronous motor of the tunneling type are as follows: figure 1 Shown: the coaxiality requirements of the two bracket holes are relatively strict. In order to ensure the coaxiality requirements of the two holes, it is necessary to make the two holes be machined with one knife in one clamping and positioning as much as possible. Due to the longer size (A+2B), the size of the bracket aperture C, D is in Left and right, the hole diameter is small, if a tool holder is designed so that after the first bracket hole is processed, the second bracket hole can be processed without moving the workpiece. The production process is More difficult to achieve. The coaxiality...
