Embodiment Construction

[0013] Such as figure 2 Shown is a structural schematic diagram of an embodiment of the present invention, an axial gap detection tool for detecting the gap between the rotor and the end cover, including a bracket 2 and a dial indicator 1, the dial indicator 1 is fixed on the bracket 2, and the front end of the bracket There is also a connection structure 21 fixedly connected to the motor shaft. The thimble of the dial indicator protrudes forward and touches the motor end cover. Put the cover on, at this time, adjust the scale of the dial indicator to zero, then fix the motor shaft, apply force to the bracket 2 and pull it until the bracket cannot move, read the scale value of the dial indicator, and calculate the corresponding value.

[0014] In this embodiment, the connection structure 21 includes an axial groove 212 provided on the front end surface of the bracket and an axial groove 212 provided at the front end of the bracket and extending into the axial groove to fix th...

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 [0001] The invention relates to an axial gap detecting tool for detecting the gap between a rotor and an end cover of a motor. Background technique [0002] Such as figure 1 As shown, a motor includes an end cover 02 and a rotor 01, and the rotor 01 is equipped with a motor shaft 03, and the rotor and the motor shaft are interference fit. After the assembly of the rotor 01 and the end cover 02 is completed, at the extension end of the motor shaft, the gap between the rotor and the end cover is not fixed, so the detection of the gap between the rotor and the end cover is also a necessary process of the inspection program in the inspection of the finished motor. But in actual situations, the detection of the gap between the rotor and the end cover is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an axial gap detection tool for detecting the gap between the rotor and the end co...
