Description

[0047] The magnetic steel angle indexing device solves the technical problem of uneven gap when the magnetic steel sheet is bonded to the rotor shaft in the related technology. It can be manufactured and used, and achieves the positive effect of relatively uniform gap. The overall idea is as follows:

[0048] One implementation method:

[0049] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown; the magnetic steel angle indexing device comprises: a servo electric indexing plate 10 for rotating the angle; and also comprises:

[0050] A basic support seat 20, the top of which is connected to the servo electric indexing plate 10;

[0051] The clamping member 30 is used to clamp the rotor shaft 100. The clamping member 30 is connected to the servo electric indexing plate 10. The servo electric indexing plate 10 links the clamping member 30 and the rotor shaft 100 to rotate an angle, thereby changing the angle of the rotor shaft 100.

[0052] A first movable guide member 40 is connected to the top of the base support seat 20 and is disposed on one side of the servo electric indexing plate 10;

[0053] and a positioning member 50, the bottom of which is connected to the first movable guide member 40, and moves along the first movable guide member 40 to contact or separate from the rotor shaft 100;

[0054] The positioning member 50 has a first state and a second state;

[0055] The first state is a state of contact with the rotor shaft 100. The adhesive is applied to the rotor shaft 100, the positioning member 50 is in contact with the rotor shaft 100, the magnetic steel sheet 200 contacts the positioning member 50 and the adhesive, and the magnetic steel sheet 200 is bonded to the rotor shaft 100. The adhesive is preferably an anaerobic adhesive, which is firmly bonded and does not require special treatment.

[0056] The second state is a state separated from the rotor shaft 100, and the positioning member 50 is spaced apart from the rotor shaft 100;

[0057] Specifically, during implementation, a servo electric indexing plate 10, a base support seat 20, a clamping member 30, a first moving guide member 40 and a positioning member 50 are provided;

[0078] The second movable guide 52 is a second linear slide rail, the number of which is one and connected to a side wall of the second plate 51-2; the second linear slide rail is a common structure in the prior art, such as MGNR12 type, including a second slider and a second slide rail, the second slider is connected to the second plate 51-2 by a bolt, and the second plate 51-2 slides along the second slide rail to adjust the position of the contact positioning portion 53;

[0079] The positioning member 50 also has a third state; in the third state, the contact positioning portion 53 on the positioning member 50 moves up and down along the second moving guide member 52. In order to fix the contact positioning portion 53 after reaching the moving position, at least one threaded pin is provided on the side wall of the second slider, and the threaded pin abuts against the second slide rail, and the second slider is limited, so that the contact positioning portion 53 is fixed, so that the contact abutting position between the contact positioning portion 53 and the rotor shaft 100 is adjusted, and multiple layers of magnetic steel sheets 200 can be bonded to the rotor shaft 100, for example: two layers, six magnetic steel sheets 200 in each layer, and the layers are arranged at intervals;

[0080] Since the positioning member 50 has a first state, a second state and a third state, the operation flexibility is good and the use is convenient;

[0081] The second movable guide 52 and the first movable guide 40 form an angle of 90°. The angle is set so that when the second movable guide 52 is in a vertical straight line state, the first movable guide 40 is in a horizontal straight line state, which is conducive to the positioning member 50 moving along the first movable guide 40 along a straight line, and the contact positioning portion 53 moving along the second movable guide 52 along a straight line, and the movement is smoother.

[0082] The contact positioning portion 53 includes: a fourth plate 53-1, connected to the second slider on the second movable guide 52, and the fourth plate 53-1 moves along the second slide track on the second movable guide 52 together with the second slider; a fixing seat 53-2, connected to the fourth plate 53-1; and a positioning piece 53-3, one end of which is connected to the fixing seat 53-2, and the other end protrudes from the fixing seat 53-2, and is used to contact and abut against the rotor shaft 100, and the positioning piece 53-3 is made of aluminum or stainless steel;

[0084] The fixing seat 53-2 includes: a fifth plate 53-21, connected to the fourth plate 53-1; and a sixth plate 53-22, connected to the fifth plate 53-21, connected to the positioning piece 53-3; the fifth plate 53-21 is a square plate structure, made of aluminum, and connected to the fourth plate 53-1 by bolts; the sixth plate 53-22 is a square plate structure, smaller in size than the fifth plate 53-21, made of aluminum, and one end is plugged or welded to the fifth plate 53-21;

[0085] The positioning sheet 53-3 is a rectangular sheet structure, one end of which is connected to the sixth plate 53-22 by a bolt, and the other end protrudes from the sixth plate 53-22, and contacts and abuts against the rotor shaft 100. When the magnetic steel sheet 200 is bonded, one side wall of the magnetic steel sheet 200 contacts and abuts against the other end of the positioning sheet 53-3, and the magnetic steel sheet 200 is positioned. The positioning sheet 53-3 is made of aluminum or stainless steel, which has a magnetic isolation effect. When bonding, the magnetic steel sheets 200 will not attract or repel each other, and the position is more accurate.

[0086] Regarding the rotor shaft 100 and the magnetic steel sheet 200:

[0087] See Figure 1 , Figure 4 One end of the rotor shaft 100 is clamped by the clamping member 30 and vertically connected to the clamping member 30. Adhesive is applied to the rotor shaft 100. The transverse section of the magnetic steel sheet 200 can be an arc-shaped structure with an arc-shaped surface. When the arc-shaped surface is bonded with the adhesive, it is more matched with the shape of the rotor shaft 100 (the part of the rotor shaft 100 to which the magnetic steel sheet 200 is bonded is cylindrical). The operator holds the magnetic steel sheet 200, and the magnetic steel sheet 200 contacts the positioning sheet 53-3 and the adhesive, and the magnetic steel sheet 200 is bonded to the rotor shaft 100.

[0088] The working principle is as follows: during operation, one end of the rotor shaft 100 is clamped by the clamping member 30 and vertically connected to the clamping member 30, adhesive is applied to the rotor shaft 100, the positioning member 50 starts in the second state, and the positioning member 50 moves along the first moving guide member 40 until the first state is formed, the positioning piece 53-3 contacts and positions the rotor shaft 100, the magnetic steel sheet 200 contacts the positioning piece 53-3 and the adhesive, and the magnetic steel sheet 200 is bonded to the rotor shaft 100;

[0089] The positioning member 50 moves from the first state to the second state along the first moving guide member 40, and the servo-electric indexing plate 10 is actuated to link the clamping member 30 and the rotor shaft 100 to rotate an angle, thereby changing the angle of the rotor shaft 100;

[0090] The positioning member 50 starts from the second state and bonds the next magnetic steel sheet 200, and repeats this process.
