Description

Technical Field

[0001] The invention relates to a portable motor stator magnetic shoe angle detector and a detection method thereof. Background Art

[0002] The motor casing has a process of pressing magnetic tiles, and the magnetic tiles must be installed according to the designed angle. The installation angle is one of the important factors affecting the speed of the DC motor. In the prior art, a projector is used to measure the angle of the casing magnetic tiles. The projector has a slow measurement speed, cumbersome operation, and low efficiency. It is also almost impossible for the inspection equipment to flow. Usually, people can only follow the machine. When different products are produced intermittently, inspectors are required to constantly test the angle of the casing magnetic tiles back and forth, which greatly increases the inspector's workload and seriously affects the inspection efficiency.

[0030] The present invention will be further described with reference to the accompanying drawings:

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a portable motor stator magnetic shoe angle detector comprises:

[0032] A magnetic tile clamp fixing block 1, a pair of gaps 71 on both sides of which can be respectively inserted into the magnetic tile 7 of the motor; the pair of gaps 71 are symmetrically arranged; a dial plate 2, which is fixed to the magnetic tile clamp fixing block 1, the central axis of the dial plate 2 coincides with the central axis of the magnetic tile clamp fixing block 1, and the dial plate 2 is provided with an angle scale;

[0033] The positioning base 4 has positioning posts 3 fixed at both ends thereof. The two positioning posts 3 can be respectively inserted into the two flange fixing holes 61 of the motor housing 6. The positioning base 4 is provided with a reference scale 41;

[0034] The central shaft 5 passes through the central hole of the positioning card seat 4, the central hole of the dial 2 and the central hole of the magnetic tile clamp fixing block 1 in sequence. The central shaft 5 is fixed to the central hole of the positioning card seat 4, the central hole of the dial 2 or the central hole of the magnetic tile clamp fixing block 1. The magnetic tile clamp fixing block 1 and the dial 2 can rotate relative to the positioning card seat 4.

[0035] The reference scale 41 can be aligned with a certain angle scale of the dial 2, so that the installation angle of the magnetic tile 7 can be obtained.

[0036] It should be noted that the motor is usually provided with a flange fixing hole 61. The installation angle of the magnetic tile is based on the flange fixing hole 61. The present invention saves the projector and greatly reduces the cost. Since the detector is small in size, easy to carry, flexible in detection, and not restricted by the site.

[0037] It should also be noted that the magnetic tiles are available in specifications of 2, 4, 6, etc. This embodiment shows 2 magnetic tiles, but is also applicable to motors with 4 or 6 magnetic tiles.

[0038] When the magnetic tile clamp fixing block 1 is inserted into the gap 71 of the magnetic tile 7, if the installation of the magnetic tile 7 meets the design requirements, the positioning column 3 can be directly inserted into the two flange fixing holes 61 of the motor housing 6, otherwise, the positioning socket 4 can only be rotated by an angle to be inserted into the two flange fixing holes 61. At this time, the rotation angle of the dial 2 is the angle of the installation deviation of the magnetic tile 7. The detection of the present invention is very simple and effective.

[0039] Furthermore, if Figure 2 and Figure 5As shown, the angle scale is located on the outer ring of the dial 2, and the inner ring of the dial 2 is provided with two annular grooves 21, through which the positioning column 3 passes. This method can increase the diameter of the dial 2 and improve the accuracy of the scale.

[0040] Preferably, observation windows 42 are provided at both ends of the positioning card seat 4, and the observation windows 42 can display the angle scale of the dial 2, and the reference scale 41 is arranged at the center position outside the observation window 42. This solution can make the reading clearer.

[0041] Preferably, the positioning card seat 4 is a rectangular block, and other shapes are obviously also possible.

[0042] Preferably, the central axis 5 is connected to the positioning holder 4 via a bearing. Providing the bearing can increase the service life of the instrument and improve its accuracy.

[0043] Preferably, the scale plate 2 and the magnetic tile clamp fixing block 1 are fixed by two screws, and this structure is convenient for installation. Usually, the thickness and width of the magnetic tile clamp fixing block 1 are adapted to the gap 71 of the magnetic tile 7, and different motor specifications are equipped with different magnetic tile clamp fixing blocks 1.

[0044] As a preference, Figure 3 As shown, a marking notch 62 is provided near one of the two flange fixing holes 61 of the motor housing 6 .

[0045] As a preference, Figure 4 and Figure 5 As shown, the angle scale of the dial 2 is 0-360 degrees. When the magnetic tile 7 is in the standard installation position, the angle scales of the dial 2 corresponding to the two reference scales 41 of the positioning seat 4 are 0 degrees and 180 degrees respectively.

[0046] A detection method of a portable motor stator magnetic tile angle detector includes a portable motor stator magnetic tile angle detector, and detection is performed according to the following steps:

[0047] S1. Insert the magnetic tile clamp fixing block 1 of the portable motor stator magnetic tile angle detector into the gap 71 of the magnetic tile 7. The angle scale of the dial 2 corresponding to the two reference scales 41 of the positioning base 4 is the actual installation angle of the magnetic tile 7.
