Composite grinder for grinding motor base

Abstract

The invention discloses a composite grinder for grinding a motor base. The composite grinder for grinding the motor base comprises a grinder body, a workpiece fixture assembly, a first grinding assembly and a second grinding assembly; the workpiece fixture assembly comprises first sliding rails, a first sliding plate, a first spindle arranged on the first sliding plate, and a workpiece fixture; the first grinding assembly comprises second sliding rails, a second sliding plate, a second spindle arranged on the second sliding plate, and a first grinding wheel; the second grinding assembly comprises fourth sliding rails, an upright, third sliding rails vertically arranged on the upright, a third sliding plate, a third spindle arranged on the third sliding plate, and a second grinding wheel; the second sliding rails and the fourth sliding rails are perpendicular to the first sliding rails; and the first spindle, the second spindle and a fourth spindle are arranged horizontally and are parallel to one another. The first grinding wheel is used to grind an internal groove of the motor base; the second grinding wheel is used to grind a splicing face of the motor base; the motor base is simply required to be clamped once, and two grinding procedures can be completed, so that the working efficiency is improved; and the deviation of a machining standard is avoided, so that the size of themotor base is more accurate and the accuracy is higher.

Description

technical field [0001] The invention belongs to the technical field of grinding machines, and in particular relates to a compound grinding machine for grinding motor seats. Background technique [0002] The splicing surface and inner groove of the motor base require high precision and need to be ground. However, the splicing surface is an exposed plane, and the inner groove includes an internal arc surface, so it cannot be processed with a grinding wheel on the same spindle. The motor seat must be removed after the grinding of the splicing surface is completed, and reinstalled on another grinding machine to grind the inner groove. The existing machining process of the motor base is too complicated, and the process of re-clamping and alignment wastes time and reduces work efficiency. At the same time, the twice-clamping will cause deviations in the machining benchmark and affect the machining accuracy. Contents of the invention [0003] In order to solve the above problems...
