Problems solved by technology

[0004] The couplings of different motors have different shapes and sizes, and the positions where the working plate is connected to the coupling are also different, so the working plates are also different. In addition, the interference between the shaft extension of different motors and the coupling is different, so the distance plate The thickness is also different. These factors lead to many types of special positioning tooling, high cost, and increased management workload
In addition, the working plate of the special coupling positioning tool needs to disassemble a large number of threaded joints every time, which is more troublesome to operate and reduces the test efficiency.

Embodiment 1

[0028] Figure 3 to Figure 4 An embodiment of the present invention is shown. The permanent magnet motor test coupling universal positioning device of this embodiment includes a magnetic mounting assembly 2 arranged on the end face of the coupling 1, and is used to make the magnetic mounting assembly 2 and the coupling The switch part 3 that is attracted or separated from the end face of the device 1, and the telescopic distance measuring component 4 are installed on the magnetic installation component 2.

[0029] The permanent magnet motor test coupling positioning device uses the magnetic installation component 2 to realize the installation on the coupling 1, uses the switch part 3 to control the attraction and separation of the magnetic installation component 2 and the coupling 1, and uses the telescopic The distance measuring component 4 is used to control the relative position of the coupling 1 and the shaft extension 51, that is, to control the press-fitting stroke. The...

Embodiment 2

[0034] The general positioning device of the permanent magnet motor test shaft coupling of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0035] In this embodiment, the telescopic distance measuring assembly 4 includes a stroke ranging rod 41, a stroke rod 42 and a set screw 43, and the magnetic base 21 is arranged on the end face of the shaft coupling 1 near the motor 5 (the right end face in the drawings ), the stroke distance measuring rod 41 is installed on the magnetic base 21 and arranged axially, one end of the stroke rod 42 is socketed with the stroke distance measuring rod 41 and fixed by the set screw 43, and the other end of the stroke rod 42 is offset against the motor 5. When in use, clean the coupling 1 and assemble it with the shaft extension 51 of the motor 5 at room temperature, push the coupling 1 until it cannot move on the shaft extension 51, and connect the magnetic base 21 to the right end of the coupling 1 The end ...

Embodiment 3

[0037] The general positioning device of the permanent magnet motor test shaft coupling of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0038] In this embodiment, the magnetic mounting assembly 2 includes a working plate 22, and a magnetic steel 23 is embedded on the working plate 22. The magnetic steel 23 uses its own magnetism to connect with the end face of the coupling 1 away from the motor 5 side (the left end in the accompanying drawings). end face), the working plate 22 is provided with a magnetic steel pressing block 24 for pressing the magnetic steel 23 onto the end face of the coupling 1. When the shape and size of the coupling 1 are different, after adjusting the position of the magnetic steel 23, the magnetic steel pressing block 24 can be used. The steel pressing block 24 fixes the magnetic steel 23 so as to adapt to shaft couplings 1 of different sizes.

Abstract

The invention discloses a universal positioning device for a permanent magnet motor test coupling. The universal positioning device comprises a magnetic installation assembly arranged on the end faceof the coupling, a switch part used for enabling the magnetic installation assembly to be attracted to or separated from the end face of the coupling, and a telescopic distance measuring assembly, wherein the switch part and the telescopic distance measuring assembly are arranged on the magnetic installation assembly. The universal positioning device has the advantages of being simple in structure, convenient to operate, universal and the like.

Description

technical field [0001] The invention relates to a permanent magnet motor test auxiliary tooling, in particular to a universal positioning device for a permanent magnet motor test shaft coupling. Background technique [0002] The permanent magnet motor needs to undergo a factory test before leaving the factory. During the test, it is generally dragged and rotated by another motor. The test drag motor is called a test motor, and a rigid flange type is generally used between the test motor and the test motor. Coupling connection, coupling and motor shaft extension (the external interface where the motor transmits the rotational motion, or the part where the motor shaft extends out of the motor body, generally 1:10, 1:20 or 1:50) The interference fit between the conical surfaces) is used to ensure the transmission of the motor torque. The size of the interference allocation between the test coupling and the shaft extension is controlled by the change of the relative distance be...
