Abstract
The invention relates to the technical field of motor component measuring equipment, and especially relates to a universal measuring instrument of a motor rotor external diameter. The universal measuring instrument of the motor rotor external diameter comprises a base plate, a central positioning rod and measuring pins. The central positioning rod is arranged on the center of the base plate. Four measuring pins are uniformly arranged on the periphery of the central positioning rod. The measuring pins are connected to the periphery of the central positioning rod through steel tapes. The measuring pins are arranged on tape strip head parts of the steel tapes. A fixed precision ruler is arranged on one side of scales of each steel tape. The measuring pins are telescopic. Four steel tape boxes are uniformly arranged below the base plate along the center. Each steel tape box is internally provided with a winding roller, and the steel tape is winded on the winding roller. The improved universal measuring instrument of the motor rotor external diameter has the advantages that the structure is simple, the operation is convenient, multi-directional accurate measurement of each motor rotor external diameter is realized, the additional reworking caused by unqualified motor rotor external diameters is avoided, the motor maintenance efficiency is greatly improved, and the motor maintenance reliability is improved.
Description
Technical field
The present invention relates to motor component technical field of measuring equipment, especially a kind of rotor external diameter Universal testing machine.
Background technology
Each locomotive engine, in maintenance process, all needs to measure rotor external diameter, to determine the air gap between the deflection of rotor and electric machine rotor, judges the impact of magnetic flux on motor performance with this.Existing motor is in actual maintenance process, rotor diameter is not often measured or only less to external diameter rotor outside micrometer is measured, but the position that outside micrometer is measured can not ensure it is the diametrical position of rotor, the motor that rotor diameter is greater than outside micrometer maximum range cannot be measured especially, define some characteristics of motor and indirectly judge by accident, the situation causing the no-load characteristic of some motors, speed characteristic and commutating characteristics not to meet maintenance requirement occurs.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of rotor external diameter Universal testing machine.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rotor external diameter Universal testing machine, comprise chassis, central locating rod and measurement pin, center chassis is provided with central locating rod, peripheral uniform four of central locating rod measures pin, measure pin and be connected to central locating rod periphery by steel tape, measure pin and be located at the chi bar head of steel tape, steel tape side with a scale is provided with fixed precision chi.
According to another embodiment of the invention, measurement pin is comprised further scalable.
According to another embodiment of the invention, comprise further below chassis and be centrally laid with four steel tape boxes.
According to another embodiment of the invention, comprise further in steel tape box and be provided with wind-up roll, steel tape is wound on wind-up roll.
The invention has the beneficial effects as follows, structure is simple, easy to operate, realize the multi-faceted Measurement accuracy to each rotor external diameter, the work of doing over again increased because rotor diameter is undesirable can be avoided, substantially increase machinery check and repair efficiency, improve machinery check and repair reliability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is front view of the present invention.
Fig. 2 is vertical view of the present invention.
1. chassis, 2. central locating rod in figure, 3. measure pin, 4. steel tape, 5. fixed precision chi, 6. steel tape box, 7. wind-up roll.
Embodiment
As Fig. 1, shown in 2, a kind of rotor external diameter Universal testing machine, comprise chassis 1, central locating rod 2 and measurement pin 3, center, chassis 1 is provided with central locating rod 2, peripheral uniform four of central locating rod 2 measures pin 3, measure pin 3 and be connected to central locating rod 2 periphery by steel tape 4, measure the chi bar head that pin 3 is located at steel tape 4, steel tape 4 side with a scale is provided with fixed precision chi 5, measure pin 3 scalable, four steel tape boxes 6 are centrally laid with below chassis, wind-up roll 7 is provided with in steel tape box 6, steel tape 4 is wound on wind-up roll 7.
During use, the center positioning hole of motor rotor shaft to be measured is directly enclosed within central locating rod 2, four steel tapes 4 move radially to measure rotor diameter, each steel tape length is 2450mm, top reading is 50mm, end reading is 2500mm, so the measurement range of this external measuring instrument is 100 ~ 5000mm, steel tape measuring accuracy is 1mm, fixed precision chi 5 measuring accuracy is 0.1mm, the radial translation of steel tape 4 can be guided, prevent steel tape 4 from offseting, measuring accuracy can be improved again, meet the measurement requirement of the various rotor external diameter of locomotive, measuring pin 3 is scalability, axial distance can be adjusted according to the distance between rotor end face and rotating shaft end face, because flexible measurement pin 3 root and steel tape 4 end are connected, so rotor diameter dimensional measurement can be synchronous with axial distance adjustment, central locating rod 2 correctly can locate the center of rotor, and the multi-faceted correct measurement of rotor external diameter is realized by its rotational, wind-up roll 7 pairs of steel tapes 4 carry out orderly rolling, steel tape box 6 pairs of steel tapes 4 play good proofing dust and protecting effect.
Rotor external diameter Universal testing machine structure after improvement is simple, easy to operate, realize the multi-faceted Measurement accuracy to each rotor external diameter, the work of doing over again increased because rotor diameter is undesirable can be avoided, substantially increase machinery check and repair efficiency, improve machinery check and repair reliability.
