Description

Technical Field

[0001] The utility model relates to the technical field of magnetic tile installation, in particular to a positioning tool for magnetic tiles of a permanent magnet motor. Background Art

[0002] Magnetic tiles are mainly used in permanent magnet motors. They exist in the form of tiles and provide the necessary magnetic field for the motor. The use of this magnetic material enables the interaction between the magnetic tiles and the motor coils to generate a magnetic field, thereby driving the motor to rotate. When current passes through the motor coil, the magnetic tiles will cause the magnetic lines of force around the coil to change, generating an interactive torque that drives the rotor to rotate.

[0003] At present, the magnetic tiles are generally installed manually. However, the polarity direction of the permanent magnet motor magnet and the magnetic tiles are the same, which has a large repulsive force. The manual installation of the magnetic tiles is not accurate enough, resulting in errors in the position and spacing of the magnetic tiles after installation, thus affecting the performance of the motor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a positioning fixture for permanent magnet motor magnetic tiles, which solves the problem of insufficient precision in the manual installation of magnetic tiles in the prior art.

[0005] According to the embodiment of the utility model, the utility model adopts the following technical solution:

[0006] A positioning tool for permanent magnet motor magnetic tiles, used for installing magnetic tiles, comprising:

[0007] The top surface of the mounting seat is concave downward to form a positioning groove for mounting the magnetic tile, and a positioning block for positioning the magnetic tile is provided on one side of the positioning groove;

[0008] An extrusion block, the mounting seat is provided with a mounting rod, the extrusion block is sleeved on the mounting rod, and one end of the extrusion block extends downward into the positioning groove; and

[0011] Preferably, the mounting seat is provided with a limiting rod, and the extrusion block is sleeved on the limiting rod.

[0012] Preferably, a cushion block is provided at the end of the limiting rod, and the extrusion block abuts against the top of the cushion block so that a gap exists between the extrusion block and the mounting seat.

[0016] Preferably, a handle is fixedly provided on another rotating shaft of the pressing cylinder.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In this scheme, the positioning groove can provide an initial installation position for the magnetic tile, so that the magnetic tile can always be located in the positioning groove, playing a role of preliminary positioning and restriction. After the magnetic tile is placed in the positioning groove, the end of the magnetic tile can be squeezed under the action of the extrusion block, so that the other end of the magnetic tile abuts against the positioning block, ensuring that the axis of the magnetic tile corresponds to the axis of the positioning groove.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, the embodiment of the utility model provides a positioning tool for permanent magnet motor magnetic tiles, which is used to install magnetic tiles, including:

[0025] The top surface of the mounting seat 1 is concave downward to form a positioning groove 3 for mounting the magnetic tile, and a positioning block 4 for positioning the magnetic tile is provided on one side of the positioning groove 3;

[0026] The extrusion block 2 and the mounting seat 1 are provided with a mounting rod 7, the extrusion block 2 is sleeved on the mounting rod 7, and one end of the extrusion block 2 extends downward into the positioning groove 3; and

[0027] The pressing cylinder 6 is located inside the positioning groove 3 and is used to position the magnetic tile in the positioning groove 3 .

[0028] In the embodiment of the utility model, a positioning groove 3 is provided on the mounting seat 1. The positioning groove 3 is in the shape of an arc and corresponds to the shape of the magnetic tile. Under the action of the positioning groove 3, an initial mounting position can be provided for the magnetic tile, so that the magnetic tile can always be located in the positioning groove 3, playing a preliminary positioning and limiting role; after the magnetic tile is placed in the positioning groove 3, the magnetic tile can be adjusted again by the extrusion block 2. The extrusion block 2 is in the shape of an "L" shape, and one end of the extrusion block 2 directly extends into the positioning groove 3. When the magnetic tile is installed, the extrusion block 2 can be lifted to make room for the installation of the magnetic tile. When the magnetic tile enters the positioning groove 3, the extrusion block 2 can be used to adjust the magnetic tile again. One end of the pressing block 2 is in direct contact with one end of the magnetic tile, and the extrusion block 2 is returned to its original position, so that the extrusion block 2 applies a certain extrusion force to the end of the magnetic tile, so that the other end of the magnetic tile abuts against the positioning block 4, ensuring that the axis of the magnetic tile corresponds to the axis of the positioning groove 3; finally, the pressing cylinder 6 is directly placed in the positioning groove 3, so that the outer circle of the pressing cylinder 6 abuts against the inner circle of the magnetic tile, and the outer circle of the magnetic tile fits the positioning groove 3 to achieve the final positioning, so that the connection between the rotor and the magnetic tile no longer requires manual positioning, which greatly reduces the difficulty of installing the magnetic tile, improves efficiency, and ensures the installation accuracy of the magnetic tile, indirectly ensuring the quality of the motor. After the magnetic tile is positioned, the pressing cylinder 6 can be removed. At this time, the magnetic tile remains stationary under the action of the extrusion block 2, and then AB glue is applied to the inner avoidance surface of the magnetic tile, and then the rotor is directly placed in the positioning groove 3 to install the magnetic tile coated with AB glue on the rotor. Wait for the AB glue to solidify to complete the installation, and the operation is simple.

[0029] Specifically, Figure 2 and Figure 3 As shown, the mounting rod 7 is sleeved with a spring 11, and the spring 11 abuts against the top of the extrusion block 2; under the action of the spring 11, a certain downward pressure can be given to the extrusion block 2. After the extrusion block 2 is lifted, the spring 11 can be compressed. When the magnetic tile is placed in the positioning groove 3, the extrusion block 2 can be directly released, so that the extrusion block 2 automatically abuts against the end of the magnetic tile under the action of its own gravity and the return of the spring 11, thereby increasing the positioning effect of the magnetic tile.

[0030] Specifically, Figure 1As shown, the mounting seat 1 is provided with a limiting rod 10, and the extrusion block 2 is sleeved on the limiting rod 10; under the action of the limiting rod 10, the extrusion block 2 can be limited so that it can only move along the axis of the limiting rod 10, thereby preventing the extrusion block 2 from deflecting.

[0031] Specifically, Figure 3 As shown, a cushion block 8 is provided at the end of the limiting rod 10, and the extrusion block 2 abuts against the top of the cushion block 8 so that there is a gap between the extrusion block 2 and the mounting seat 1, so that when the extrusion block 2 is adjusted, the gap facilitates the fingers to enter the bottom of the extrusion block 2, so as to facilitate the adjustment of the extrusion block 2, providing convenience.

[0032] Based on the above scheme, Figures 1 to 3 As shown, limiting plates 9 are provided on both sides of the mounting seat 1 to make the positioning groove 3 form a closed groove body; the limiting plate 9 is also provided with an arc groove, and the radius of the arc groove is smaller than the radius of the positioning groove 3, so that the side of the limiting plate 9 is higher than the edge of the positioning groove 3, so that the ports on both sides of the positioning groove 3 can be closed by the limiting plate 9, which can ensure that the magnetic shoe placed in the positioning groove 3 will not be offset, play a role in limiting the magnetic shoe, ensure that the magnetic shoe is stably placed in the positioning groove 3, and can also position the subsequent rotor, further ensuring the installation positioning effect.

[0033] Specifically, Figure 1 and Figure 3 As shown, the two limit plates 9 are both provided with mounting plates 5, and the two mounting plates 5 are both provided with mounting grooves 501. The rotating shaft of the pressing cylinder 6 is arranged between the two mounting grooves 501, providing an installation position for the installation of the pressing cylinder 6. When the pressing cylinder 6 is used, the pressing cylinder 6 can be directly arranged between the two mounting grooves 501, and the magnetic tile in the positioning groove 3 can be positioned under the gravity of the pressing cylinder 6; secondly, a mounting shaft 502 is arranged in one of the mounting grooves 501, and one of the rotating shafts of the pressing cylinder 6 is rotatably arranged on the mounting shaft 502. Under the action of the mounting shaft 502, it is fixedly connected with the rotating shaft of the pressing cylinder 6, so that the pressing cylinder 6 can rotate with the mounting shaft 502 as the axis. When the pressing cylinder 6 is used for positioning each time, there is no need to frequently disassemble the pressing cylinder 6. It is only necessary to lift one end of the pressing cylinder 6 to rotate and install the magnetic tile, and the other rotating shaft of the pressing cylinder 6 is placed in the mounting groove 501 to complete the positioning. Furthermore, a handle 12 is fixedly provided on the other rotating shaft of the pressing cylinder 6, so that the pressing cylinder 6 can be adjusted manually, which is more convenient and labor-saving.

[0034] In summary, the present invention can pre-position the magnetic tile by setting the positioning groove 3, so that the magnetic tile will not be offset, and the stability of the magnetic tile in the positioning groove 3 can be guaranteed under the action of the positioning groove 3 and the extrusion block 2, and finally the final pressing and positioning is implemented by the pressing cylinder 6. Under the support of the extrusion block 2, it can be ensured that after the pressing cylinder 6 is separated from the magnetic tile, the magnetic tile will not separate from the positioning groove 3. After the rotor is installed in the positioning groove 3, the magnetic tile will not move under the action of magnetism. The repulsive force is completely absorbed by the mounting seat 1, which not only releases manpower but also improves the stability and accuracy of the magnetic tile installation, thereby ensuring the quality of the motor.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
