Abstract
The present invention belongs to a gauge used in a motor assembly process, and particularly relates to a spline hole and outer ring concentricity gauge of a motor pressing ring. The gauge comprises a spline shaft and an outer ring inspection tool. Insertion matching is formed by the spline shaft and the end part spline hole of the motor pressing ring. Sleeve connection matching is formed by the outer ring inspection tool and the short shaft outer ring of the motor pressing ring. The spline shaft is fixed in the detection hole of the outer ring inspection tool, and the axis of the spline shaft and the detection hole axis of the outer ring inspection tool are collinear. According to the gauge, a spline gauge and an outer ring gauge are combined skillfully to detect the concentricity of the spline hole and outer ring of the motor pressing ring, thus the concentricity of the outer ring of a motor pressing short shaft and a motor spindle are indirectly detected, the bearing installation accuracy is ensured, and the overall assembly quality of the motor is improved.
Description
Technical field
The invention belongs to the cubing used in motor assembling process, be specifically related to splined hole and the cylindrical concentricity check tool of a kind of motor trim ring.
Background technology
Motor trim ring is the disc-shaped structure on electric machine main shaft, and its effect is to be compressed by rotor core. Due to the restriction of actual production technique, motor trim ring and electric machine main shaft are often independent machine-shaping, then pass through hot cover process and both are coaxially fixed. Motor trim ring mainly includes a disk, and disc centre is provided with and the installing hole of electric machine main shaft socket, is provided with one section of short axle outside disk (namely away from the side of main shaft). Motor trim ring is in the course of processing, its installing hole coordinated with main shaft and splined hole are to impose uniformity without examining individual cases to be whittled into type, therefore after motor trim ring and spindle mounted are good, the axiality of splined hole and electric machine main shaft is able to guarantee, but the periphery in above-mentioned short axle portion and installing hole need to be processed at twice, this is possible to cause that short axle periphery and installing hole concentricity exist deviation, and then after motor trim ring and electric machine main shaft assemble, the concentricity of this short axle periphery and electric machine main shaft is read less than guarantee. The more important thing is that the effect of this short axle is to install bearing for the later stage, if the outer ring surface Concentricity tolerance of short axle is relatively big, motor bearings damage and motor oscillating and throat sound defect being caused, thus affecting the performance of the motor after having assembled.
Summary of the invention
It is an object of the invention to provide the cubing of a kind of splined hole for detecting motor trim ring and cylindrical concentricity.
For achieving the above object, the invention provides techniques below scheme: the splined hole of a kind of motor trim ring and cylindrical concentricity check tool, the splined shaft that grafting coordinates is constituted including the end spline hole with motor trim ring, and the cylindrical inspection rule that socket coordinates are constituted with the short axle periphery of motor trim ring, described splined shaft is fixed in the detection hole of cylindrical inspection rule, and the detection axially bored line conllinear that the axis of splined shaft is advised with cylindrical inspection.
The method have technical effect that: the present invention by spline cubing and the ingenious combination of cylindrical cubing to detect splined hole and the cylindrical concentricity of terminal trim ring, thus the concentricity of the cylindrical of the short axle of indirect detection motor trim ring and electric machine main shaft, guarantee bearing installation accuracy, improve the integral installation aglycon amount of motor.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention.
Fig. 2 is the sectional view that the present invention uses state.
Detailed description of the invention
As shown in Figure 1, 2, the splined hole of a kind of motor trim ring and cylindrical concentricity check tool, the splined shaft 1 that grafting coordinates is constituted including the end spline hole a1 with motor trim ring a, and the cylindrical inspection rule 2 that socket coordinates are constituted with the short axle periphery a2 of motor trim ring a, described splined shaft 1 is fixed in the detection hole 21 of cylindrical inspection rule 2, and the axis of splined shaft 1 advises detection hole 21 axis collinear of 2 with cylindrical inspection. owing to motor trim ring a and the main shaft b installing hole coordinated and splined hole a1 are time processing molding, therefore after motor trim ring a is good with spindle mounted, the axiality of splined hole a1 and electric machine main shaft b is able to guarantee, the present invention first guarantees the concentricity of splined shaft 1 and cylindrical inspection rule 2 in assembling process, splined shaft 1 is inserted by detection process in the splined hole a1 of motor trim ring, if the detection hole 21 of now cylindrical inspection rule 2 can be enclosed within the short axle periphery a2 of motor trim ring a smoothly, then prove that the concentricity of the short axle periphery a2 and splined hole a1 of motor trim ring a is reliable, and then determine that the concentricity of short axle periphery a2 and electric machine main shaft b is reliable.
Preferably, having an installing hole 22 bottom the detection hole 21 of described cylindrical inspection rule 2, this installing hole 22 is coaxial with detection hole 21, and described splined shaft 1 one end is coaxially extended has one section to connect axle 11, described connection axle 11 is plugged in installing hole 22, and both constitute interference fit.
Preferably, the diameter of described connection axle 11 and installing hole 22 is less than the external diameter of splined shaft 1, in order to assembling location.
Further, described connection axle 11 runs through at the bottom of the hole, detection hole 21 of cylindrical inspection rule 2, and 2 outer ends are extended one handle 12 to cylindrical inspection rule, it is preferred that described handle 12 is provided with annular knurl; The periphery of described cylindrical inspection rule 2 is provided with annular knurl, in order to operator grip.
Spline cubing and the ingenious combination of cylindrical cubing are detected splined hole a1 and the periphery a2 concentricity of motor trim ring a by the present invention, thus the concentricity of the short axle periphery a2 of indirect detection motor trim ring a and electric machine main shaft b, guarantee bearing installation accuracy, improve the integral installation aglycon amount of motor.
