Abstract
The utility model discloses a motor axial clearance detection device, which comprises a base, wherein a mounting rack for fixing a motor is arranged on the base, a pair of push-pull force meters positioned at two sides of the mounting rack is arranged on the base in a sliding manner, a bracket is arranged on the base, a dial indicator is arranged on the bracket, the motor axial clearance detection device also comprises a connecting plate arranged on a motor rotating shaft, and each push-pull force meter push rod is coaxial with the motor rotating shaft; by adopting the motor axial clearance detection device with the structure, because the motor shaft clearance is detected through the push-pull dynamometer, the thrust can be directly read out, the thrust can be kept in a stable range during detection at each time, the obtained detection data is more accurate, and the problem of large measurement precision deviation is reduced.
Description
Technical Field
The utility model relates to a motor axial clearance detection device.
Background
The axial clearance of the motor is one of indexes for detecting the physical characteristics of the whole motor, and refers to the axial movable distance which must exist on the premise that a rotor of the motor is axially limited by a stator, an end cover and other parts, which is called axial play amount for short, and the fit clearance between a motor shaft and the rotor is a main reason for causing the motor shaft to play. The axial play amount of the motor is strictly limited in many fields, particularly for a satellite motor, and the axial play amount directly influences the service life of the motor, so that the detection of the axial play of the motor is an important technical index for guaranteeing whether the motor is qualified or not.
Generally, a motor stator is fixed on a tool, an operator pulls a motor shaft along an axial direction by hand until the motor shaft is not pulled, and the detection method completely depends on experience of the operator because the pulling force applied to the motor shaft by the operator cannot be measured, so that the measurement precision deviation is large and the consistency is poor.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough among the prior art, provide one kind and thrust invariant when detecting motor axial clearance, the little motor axial clearance detection device of measurement accuracy deviation, the utility model discloses the technical scheme who adopts is:
the utility model provides a motor axial clearance detection device, includes the base on be equipped with the mounting bracket of fixed motor the base on slide and be equipped with a pair of push-pull effort meter that is located the mounting bracket both sides the base on be equipped with the support on be equipped with the amesdial, still including installing the connecting plate in the motor shaft, each push-pull effort meter push rod all is coaxial with the motor shaft.
Furthermore, a pair of linear slide rails for mounting the push-pull dynamometer is arranged on the base.
By adopting the motor axial clearance detection device with the structure, because the motor shaft clearance is detected through the push-pull dynamometer, the thrust can be directly read out, the thrust can be kept in a stable range during detection at each time, the obtained detection data is more accurate, and the problem of large measurement precision deviation is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The motor axial clearance detection device shown in fig. 1 comprises a base 1, a mounting frame 2 is arranged on the base 1, a through hole is formed in the mounting frame 2, a motor to be detected is arranged at the position of the through hole, a motor shaft penetrates through the through hole, a pair of push-pull force meters 3 are arranged on the base 1 in a sliding mode, the pair of push-pull force meters 3 are arranged on two sides of the mounting frame 2 respectively, push rods of the pair of push-pull force meters 3 are coaxial with a motor rotating shaft arranged on the mounting frame 2, the device further comprises a connecting plate 6, the connecting plate 6 is arranged on the rotating shaft of the motor to be detected, a support 4 is arranged on the base 1.
In order to facilitate the smooth sliding of the push-pull dynamometer 3, a pair of linear slide rails 7 for mounting the push-pull dynamometer 3 is arranged on the base 1.
When the axial clearance of the motor is detected, the dial indicator 5 is in contact with the connecting plate 6 and displays an initial degree, the push-pull dynamometer 3 on one side is pushed to enable the motor shaft to move axially, at the moment, the connecting plate 6 moves along with the motor shaft until a value expected to be reached is displayed on the push-pull dynamometer 3, at the moment, the degree S1 is displayed on the dial indicator 5, the push-pull dynamometer 3 on the other side is pushed again to enable the push-pull dynamometer 3 to push the motor shaft to reach the expected value, at the moment, the pioneer watch displays the degree S2, and the absolute value of the difference between the values of S1 and S2 is the size of the.
