Abstract
The purpose of this utility model is to disclose a kind of motor shaft centre bore radial pulsation measurement frock simple in construction, easy to operate, frock includes being used for the fixture for clamping motor shaft, motor shaft and fixture form axial limiting, circumferentially rotates and is coupled, frock also includes the cylindrical detection block being connected with the centre bore of motor, detection block side is provided with dial gauge, the end of the measurement head of dial gauge and detection block surface against.In such scheme, detection block is fixed together with centre bore, and motor shaft is rotated one week, simple and convenient using the radial beat eccentricity of dial gauge measurement detection block come the radial beat eccentricity in indirect measuring center hole.
Description
Technical field
It the utility model is related to technical field of motors, and in particular to a kind of motor shaft centre bore radial pulsation measurement frock.
Background technology
Motor shaft C-shaped center hole is to process the benchmark of rotor, and the internal thread of C-shaped center hole is installation motor tailing axle
Screw thread, its circular runout has a great influence to the motor tail shaft run-out after installation, and is usually mounted with motor tailing axle
Encoder, motor tailing axle circular runout is excessive to be had an impact to the data of encoder and life-span, so for motor shaft c-type center
The measurement of hole circular runout turns into an important step to the detection of motor encoder installation quality.
Utility model content
The purpose of this utility model is to disclose a kind of motor shaft centre bore radial pulsation measurement simple in construction, easy to operate
Frock.
To achieve these goals, the technical solution adopted in the utility model is：A kind of motor shaft centre bore circular runout
Measuring frock, frock includes being used for clamping the fixture of motor shaft, motor shaft and fixture composition axial limiting, circumferentially rotates and is coupled,
Frock also includes the cylindrical detection block being connected with the centre bore of motor, and detection block side is provided with dial gauge, the survey of dial gauge
Measure end and the detection block surface of head against.
In such scheme, detection block is fixed together with centre bore, and motor shaft is rotated one week, surveyed using dial gauge
The radial beat eccentricity for measuring detection block carrys out the radial beat eccentricity in indirect measuring center hole, simple and convenient.
Brief description of the drawings
Fig. 1 is the utility model and motor shaft cooperation schematic diagram.
Embodiment
As shown in figure 1, a kind of motor shaft centre bore radial pulsation measurement frock, frock includes being used to clamp motor shaft A's
Fixture 10, motor shaft A and fixture 10 form axial limiting, circumferentially rotates and is coupled, and frock is also including the centre bore B with motor shaft A
The cylindrical detection block 20 of connection, the side of detection block 20 are provided with dial gauge 30, the end of the measurement head 31 of dial gauge 30 and inspection
Survey the surface of block 20 against.Detection block 20 is fixed together with centre bore B, and motor shaft A is rotated one week, utilizes dial gauge 30
The radial beat eccentricity for measuring detection block 20 carrys out indirect measuring center hole B radial beat eccentricity, simple and convenient.
Further, described detection block 20 includes cylinder 21, is protruded out on one end end face of cylinder 21 and is provided with spiral shell
Post 22, stud 22 are formed with centre bore B and are threadedly coupled, and the measurement head 31 of dial gauge 30 and the surface of cylinder 21 directly abut,
The outer surface of cylinder 21 is shiny surface.It is fixedly connected by stud 22 with centre bore B, smooth outer surface can reduce measurement
Error.
In order to prevent dial gauge 30 to be subjected to displacement influence measurement accuracy, described dial gauge 30 is fixed on support 40, and hundred
The measurement head 31 of table 30 is divided to arrange straight down.
In order to smoothly support motor shaft A, fixture 10 is V-type cushion block and is provided with two, and V-type cushion block is arranged on motor shaft
Near A bearing rib, two V-type cushion blocks are highly equal.So motor shaft A shaft core is horizontal direction, improves the accurate of measurement
Degree.
