Abstract
The invention discloses an axial clearance detection fixture for detecting a clearance between a rotor and an end cover. The axial clearance detection fixture comprises a bracket (2) and a dial indicator (1), wherein the dial indicator (1) is fixed on the bracket (2), the front end of the bracket is provided with a connecting structure (21) fixedly connected with a motor rotating shaft, and a thimble (11) of the dial indicator forwards extends out and supports against the end cover of the motor. The motor rotating shaft is clamped and fixed through the bracket, the dial indicator is arranged on the bracket, and the bracket is pulled by applying force until not to be continuously pulled, the axial clearance detection tool for detecting the clearance between the rotor and the end cover completes the measurement of the clearance between the rotor and the end cover, and has the advantages of simple and convenient operation process and more accurate detection result.
Description
Technical field
The end play that the present invention relates to gap between a kind of detection rotor of motor and the end cap detects frock.
Background technology
As shown in Figure 1, a kind of motor comprises end cap 02 and rotor 01, is equipped with machine shaft 03 on the rotor 01, and rotor and machine shaft are interference fit.After rotor 01 and end cap 02 assembling are finished, at the machine shaft external part, do not fix between rotor and the end cap, so the detection of gap length also is a necessary operation of trace routine between motor finished product detection rotor and the end cap.But in actual conditions, the detection in the gap between rotor and the end cap is very inconvenient.
Summary of the invention
The end play that the technical problem to be solved in the present invention provides gap between a kind of detection rotor and the end cap detects frock, can make things convenient for the gap length between detection rotor and the end cap.
For solving the problems of the technologies described above, the technical solution used in the present invention is that the end play in gap between a kind of detection rotor and the end cap detects frock, comprise support and dial gauge, dial gauge is fixed on the support, the support front end also is provided with the syndeton of fixedlying connected with machine shaft, and the thimble of dial gauge stretches out forward and is against on the electric motor end cap.The end play in gap detects frock between described a kind of detection rotor and the end cap, by machine shaft is fixedly clamped, the back pulls to support the support application of force can not be continued pulling, read out in the scale value that demonstrates on the dial gauge this moment, operating process is simple and convenient, and testing result is comparatively accurate.
As a kind of improvement, described syndeton comprises the axial notch that is located on the support front end face and is located at the support front end and stretches in the axial notch spindle nose with machine shaft and is fixed on securing member in the axial notch.Establish axial notch at described support front end face, the spindle nose of described machine shaft puts in the axial notch, after utilize securing member that the spindle nose of machine shaft is fixedly clamped, this moment described thimble withstand on the end cap, operating process is comparatively convenient.
As a kind of improvement, described securing member is screw, and the support front end is provided with radial screw bore, and screw cooperates with radial screw bore.Adopt screw and threaded hole to be combined as securing member, process easy, easy operating, fastening effect is better.
As a kind of improvement, described axial notch cooperates with machine shaft.Syndeton selects for use axial notch and machine shaft to cooperate, and is simple in structure, easy to process, easy operating.
As a kind of improvement, described support is provided with boss, and boss is provided with axially extending bore, and the thimble sleeve pipe of dial gauge is fixed in the axially extending bore, and the thimble of dial gauge passes axially extending bore and is against on the electric motor end cap.Dial gauge is fixed on the boss on the support, and the fixation masterpiece is used on the thimble sleeve pipe of dial gauge, and what dial gauge can be more firm is fixed on the support, and can guarantee effective performance of the effect of dial gauge.
The present invention adopts the end play in gap between a kind of detection rotor and the end cap to detect frock, its beneficial effect is: the end play in gap detects frock between described a kind of detection rotor and the end cap, by support machine shaft is fixedly clamped, and install dial gauge at support, the back pulls to support the support application of force can not be continued pulling, namely finished the measurement of the gap length between rotor and the end cap, operating process is simple and convenient, and testing result is comparatively accurate.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a kind of structural representation of motor;
Fig. 2 is the structural representation of an embodiment of the present invention.
Embodiment
The structural representation of an embodiment of the present invention as shown in Figure 2, the end play in gap detects frock between a kind of detection rotor and the end cap, comprise support 2 and dial gauge 1, dial gauge 1 is fixed on the support 2, the support front end also is provided with the syndeton 21 of fixedlying connected with machine shaft, the thimble of dial gauge stretches out forward and is against on the electric motor end cap, syndeton 21 is fixedly clamped behind the machine shaft, the thimble 11 of dial gauge 1 withstands on the end cap, fix the zeroing of the scale of dial gauge then this moment with machine shaft, support 2 application of forces are pulled to support and can not move, read the dial gauge scale value, extrapolate corresponding numerical value.
In the present embodiment, described syndeton 21 comprises the axial notch that is located on the support front end face 212 and is located at the support front end and stretches in the axial notch spindle nose with machine shaft and is fixed on securing member 211 in the axial notch, machine shaft is stretched in the axial notch, be fixed in the axial notch with the spindle nose of securing member with machine shaft afterwards.
As shown in Figure 2, described securing member 211 is screw, and the support front end is provided with radial screw bore, and screw cooperates with radial screw bore, and the machine shaft rotating shaft is stretched in the axial notch, screw precession threaded hole, machine shaft is fixedly clamped then.
In the present embodiment, described axial notch cooperates with machine shaft.
In the present embodiment, described support is provided with boss 22, and boss is provided with axially extending bore 221, and the thimble sleeve pipe 12 of dial gauge is fixed in the axially extending bore, and the thimble of dial gauge passes axially extending bore and is against on the electric motor end cap.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
