Description

Technical Field

[0001] The utility model relates to the field of motor preparation, in particular to a skew assembly device for a motor rotor lamination assembly. Background Art

[0002] A motor is a device that converts electrical energy, thermal energy or chemical energy into mechanical energy and is widely used in various equipment and machinery.

[0003] Figure 1 A schematic diagram showing the structure of a worm gear of a motor rotor; Figure 2 A schematic structural diagram showing a first lamination assembly of a motor rotor; Figure 3 A schematic structural diagram showing a second lamination assembly of a motor rotor;

[0004] Figure 4 A schematic diagram showing the skew assembly of the worm and lamination assembly of the motor rotor; Figure 5 Show Figure 4 Schematic diagram of the AA' section. Figures 1 to 5 As shown, for a specific motor, its two magnetized first lamination assemblies 60 and second lamination assemblies 70 need to be pressed onto the rotor worm shaft 50 at different relative inclination angles. The different inclination angles are used to verify the motor tooth torque, and the test data is subsequently used to determine the optimal assembly inclination angle.

[0005] Figure 6 FIG. 1 is a schematic diagram showing an assembly device for a motor rotor lamination assembly of the prior art. Figure 6 As shown, in order to achieve different mutual tilt angles between the first stack assembly 60 and the second stack assembly 70, a universal magnetized stack positioning fixture is used when pressing the first stack assembly 60, and another fixture with a mutual tilt angle is used when pressing the second stack assembly 70, thereby finally achieving the assembly of the magnetized first stack assembly 60 and the second stack assembly 70 with a mutual tilt angle.

[0006] However, this means that for different mutual tilt angles, a corresponding magnetized lamination positioning fixture needs to be designed and manufactured separately. As a result, more fixtures are required for the assembly process of the lamination assembly, and the manufacturing cost is high. In addition, because different lamination assemblies need to be processed on different magnetized lamination positioning fixtures, the influence of fixture processing errors and fixture assembly dimension chains leads to large errors in the final mutual tilt angle.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0008] In view of this, the utility model provides a skew assembly device for a motor rotor lamination assembly, so as to at least solve the problem that a magnetized lamination positioning fixture needs to be designed separately for each tilt angle, and the assembly error of the tilt angle is relatively large.

[0009] The utility model provides a skew assembly device for a motor rotor lamination assembly, comprising:

[0010] A rotor worm fixing assembly, wherein the rotor worm fixing assembly is horizontally arranged, and the rotor worm shaft is connected to the lower surface of the rotor worm fixing assembly;

[0011] A guide rod assembly, wherein the guide rod assembly is vertically arranged, the rotor worm fixing assembly is sleeved on the guide rod assembly, and the rotor worm fixing assembly has a first stroke moving along the setting direction of the guide rod assembly;

[0012] A magnetized lamination fixing assembly is located below the rotor worm fixing assembly, and the first lamination assembly and the second lamination assembly are fixed above the magnetized lamination fixing assembly;

[0013] The tilt angle adjustment component is horizontally arranged, the magnetized lamination fixing component is fixed above the tilt angle adjustment component, and the magnetized lamination fixing component has a second stroke that rotates based on the horizontal rotation of the tilt angle adjustment component.

[0014] By means of the magnetized lamination fixing assembly and the tilt angle adjustment assembly, it is possible to assemble the first lamination assembly and the second lamination assembly on the rotor worm shaft at different tilt angles, and the assembly of different tilt angles can be completed by a set of motor rotor lamination assembly twisting assembly device, which is easy to operate and reduces the assembly cost; the tilt angle adjustment assembly can also reduce the error of the tilt angle during the assembly process.

[0015] In some embodiments, the rotor worm fixing assembly includes: at least one first positioning hole and a clamping block; the rotor worm shaft is sleeved on the guide rod assembly through the first positioning hole; the rotor worm shaft is connected to the rotor worm fixing assembly through the clamping block.

[0016] By setting the first positioning hole and the clamping block, it can be ensured that the axis of the rotor worm shaft is consistent with the setting direction of the guide rod assembly, and the movement direction of the rotor worm shaft is parallel to the guide rod assembly, so as to facilitate assembly with the first lamination assembly and the second lamination assembly.

[0017] In some embodiments, the guide rod assembly includes: at least one guide rod; the number of the guide rods is the same as the first positioning holes, and the guide rod is sleeved in the first positioning holes.

[0018] The design that the guide rods and the first positioning holes are provided in the same number and sleeved with each other can ensure that the rotor worm shaft is accurately aligned along the direction of the guide rod assembly during the assembly process.

[0019] In some embodiments, the guide rod assembly includes: a first guide rod and a second guide rod; a diameter of the first guide rod is greater than a diameter of the second guide rod.

[0020] The precise matching of multiple guide rods and the first positioning holes can effectively reduce the deviation that may be caused by a single support point, which helps to reduce the impact of assembly errors on the tilt angle. At the same time, different guide rod diameters can achieve assembly error prevention.

[0021] In some embodiments, the magnetized lamination fixing assembly has: a first central through hole, at least two positioning pins and a side plane; the first stroke of the rotor worm fixing assembly passes through the first central through hole; the positioning pin cooperates with the second positioning hole pin hole of the first lamination assembly and the second lamination assembly; the outward direction perpendicular to the side plane is consistent with the north pole direction of the first lamination assembly and the second lamination assembly after magnetization.

[0022] By setting the first central through hole, the first lamination assembly and the second lamination assembly are precisely aligned with the rotor worm shaft. At least two positioning pins cooperate with the second positioning hole pin holes of the first lamination assembly and the second lamination assembly to provide a reliable positioning effect, ensuring that no displacement or rotation occurs during the assembly process. The setting of the side plane ensures the consistency of the magnetic pole direction after assembly, thereby ensuring the uniformity of the magnetic field direction of the motor during operation.

[0023] In some embodiments, the tilt angle adjustment assembly includes: an angle adjustment disk and at least two locking pieces; the angle adjustment disk is horizontally arranged and has at least two waist holes; the number of the locking pieces is the same as the waist holes, and the locking pieces pass through the waist holes to lock and fix the angle adjustment disk.

[0024] The angle adjustment disk can adjust the tilt angle of the magnetized lamination fixing assembly by horizontal rotation, thereby adjusting the tilt angle of the first lamination assembly and the second lamination assembly. The waist hole design allows the locking member to move within a certain range, so that the angle adjustment disk can accurately adjust the tilt angle within a larger range.

[0025] In some embodiments, the tilt angle adjustment assembly also includes: an angle encoder, an amplifier and a computing device; the angle encoder and the magnetized stack fixing assembly rotate based on the horizontal rotation of the angle adjustment disk; the angle encoder, the amplifier and the computing device are electrically connected for reading the rotation angle of the angle adjustment disk.

[0026] The angle encoder can accurately read the rotation angle of the angle adjustment disk, and these read data can be processed and displayed through amplifiers and computing devices. This ensures that high-precision angle measurement results can be obtained when adjusting the tilt angle, thereby improving the accuracy of the assembly process and effectively reducing errors caused by visual inspection or manual measurement.

[0027] In some embodiments, the skew assembly device of the motor rotor lamination assembly also includes: a base having a second central through hole and a third positioning hole; wherein the angle adjustment disk passes through the second central through hole, and the locking member locks and fixes the angle adjustment disk and the base; and the guide rod assembly is also sleeved on the third positioning hole.

[0028] By passing the angle adjustment disk through the second central through hole and locking and fixing it, a firm connection between the angle adjustment disk and the base can be ensured, the overall stability of the assembly device can be enhanced, and the tilt angle can be easily changed.

[0029] In some embodiments, the base further has an angle scale surrounding the angle adjustment disk; the angle adjustment disk has an angle mark for matching with the angle scale to calculate the rotation angle of the angle adjustment disk.

[0030] The angle scale and angle mark allow the tilt angle to be read and adjusted intuitively, making assembly operations easier.

[0031] In some embodiments, the tilt angle adjustment assembly further includes: an angle display screen for displaying the rotation angle of the angle adjustment disk based on the rotation of the angle adjustment disk.

[0032] The angle display screen can directly display the rotation angle of the angle adjustment disk and provide a digital angle reading method. Compared with the traditional visual reading of the angle scale, it significantly improves the accuracy of angle reading, reduces reading errors, and allows for quick adjustment and confirmation.

[0080] In some embodiments, the motor may be a steer-by-wire motor, a motor for a steering system, a motor for a braking system, or the like.

[0081] In some embodiments, the connection or fixing methods of the various parts of the utility model, in addition to those already specifically defined, can be configured to be screwed, riveted, clamped or welded according to specific application conditions.

[0082] In some embodiments, the rotor worm fixing assembly 10 includes: at least one first positioning hole 11 and a clamping block 12; the rotor worm shaft 50 is sleeved on the guide rod assembly 20 through the first positioning hole 11; the rotor worm shaft 50 is connected to the rotor worm fixing assembly 10 through the clamping block 12. Specifically, the rotor worm shaft 50 can also be pre-assembled with the bearing before being connected to the rotor worm fixing assembly 10. The clamping block 12 has two locking screws to lock the rotor worm shaft 50 and the rotor worm fixing assembly 10. The number of the first positioning holes 11 can be 2. By setting the first positioning hole 11 and the clamping block 12, it can be ensured that the axis of the rotor worm shaft 50 is consistent with the setting direction of the guide rod assembly 20, and the movement direction of the rotor worm shaft 50 is parallel to the guide rod assembly 20, so as to facilitate the assembly with the first lamination assembly 60 and the second lamination assembly 70.

[0083] In some embodiments, the guide rod assembly 20 includes: at least one guide rod; the number of the guide rods is the same as the first positioning holes 11, and the guide rods are sleeved in the first positioning holes 11. The design that the guide rods are the same in number as the first positioning holes 11 and are sleeved can ensure that the rotor worm shaft 50 is accurately aligned along the direction of the guide rod assembly 20 during the assembly process.

[0084] In some embodiments, the guide rod assembly 20 includes: a first guide rod 21 and a second guide rod 22; the diameter of the first guide rod 21 is greater than the diameter of the second guide rod 22. Specifically, the diameter of the first guide rod 21 can be set to 16 mm, and the diameter of the second guide rod 22 can be set to 13 mm, but not limited thereto. Through the precise matching of multiple guide rods and the first positioning hole 11, the deviation that may be caused by a single support point can be effectively reduced, which helps to reduce the influence of assembly errors on the tilt angle, and different guide rod diameters can achieve assembly error prevention.

[0085] In some embodiments, the magnetized lamination fixing assembly 30 has: a first central through hole 31, at least two positioning pins 32 and a side plane 33; the first stroke of the rotor worm fixing assembly 10 passes through the first central through hole 31; the positioning pin 32 cooperates with the second positioning hole pin hole of the first lamination assembly 60 and the second lamination assembly 70; the direction perpendicular to the side plane 33 outward is consistent with the direction of the north pole of the magnetized first lamination assembly 60 and the second lamination assembly 70. Specifically, the first lamination assembly 60 and the second lamination assembly 70 need to be magnetized before assembly, and the first lamination assembly 60 also needs to be pre-assembled with a plastic cover. The first lamination assembly 60 and the second lamination assembly 70 are both formed by stacking a plurality of laminations. The number of positioning pins 32 can be 3. The magnetized lamination fixing assembly 30 can be made of brass material or other materials that are not easily attracted by magnets, so as not to affect the first lamination assembly 60 and the second lamination assembly 70 with strong magnetism. By setting the first central through hole 31, the first lamination assembly 60 and the second lamination assembly 70 are precisely aligned with the rotor worm shaft 50. At least two positioning pins 32 cooperate with the second positioning pin holes of the first lamination assembly 60 and the second lamination assembly 70 to provide a reliable positioning effect, ensuring that no displacement or rotation occurs during the assembly process. The setting of the side plane 33 ensures the consistency of the magnetic pole direction after assembly, thereby ensuring the uniformity of the magnetic field direction of the motor during operation.

[0086] In some embodiments, the tilt angle adjustment assembly 40 includes: an angle adjustment disk 41 and at least two locking members 42; the angle adjustment disk 41 is horizontally arranged and has at least two waist holes 43; the number of locking members 42 is the same as the waist holes 43, and the locking members 42 penetrate the waist holes 43 to lock and fix the angle adjustment disk 41. Specifically, the angle adjustment disk 41 can be set to a disc shape, and the tilt angle is adjusted in a clockwise or counterclockwise direction. The adjustment range of the tilt angle is the angle range of the smallest waist hole 43. The locking member 42 can be a quick-locking screw with a handle, and the quick-locking screw can quickly lock or loosen the angle adjustment disk 41 and the base 80 through the handle. When assembling the first stack assembly 60, the first stack assembly 60 is placed on the magnetized stack fixing assembly 30, the locking member 42 is located at one end of the waist hole 43, and the locking member 42 locks the angle adjustment disk 41. The first stack assembly 60 is pressed into the position set by the rotor worm shaft 50 using the program set by the servo press. Then pull out the rotor worm shaft 50 with the first lamination assembly 60 upward, and then assemble the second lamination assembly 70. When assembling the second lamination assembly 70, after the rotation of the angle adjustment disk 41, the waist hole 43 can be located in the middle of the waist hole 43 to the other end, and the magnetized lamination fixing assembly 30 rotates an inclined angle with the rotation of the angle adjustment disk 41. The angle adjustment disk 41 is locked again, and the second lamination assembly 70 is placed on the magnetized lamination fixing assembly 30. Then, the second lamination assembly 70 is pressed into the position set by the rotor worm shaft 50 using the program set by the servo press. The angle adjustment disk 41 can adjust the inclination angle of the magnetized lamination fixing assembly 30 by horizontal rotation, and then adjust the inclination angle of the first lamination assembly 60 and the second lamination assembly 70. The design of the waist hole 43 allows the locking member 42 to move within a certain range, so that the angle adjustment disk 41 can accurately adjust the inclination angle within a large range.

[0087] In some embodiments, the tilt angle adjustment assembly 40 further includes: an angle encoder 44, an amplifier 45, and a computing device 46; the angle encoder 44 and the magnetized stack fixing assembly 30 rotate based on the horizontal rotation of the angle adjustment disk 41; the angle encoder 44, the amplifier 45, and the computing device 46 are electrically connected to read the rotation angle of the angle adjustment disk 41. Specifically, the angle encoder 44 detects the rotation angle of the angle adjustment disk 41, and then obtains the tilt angle of the first stack assembly 60 and the second stack assembly 70. The relevant characteristics of the amplifier can refer to the specific product. The computing device 46 can be installed with decoding software in advance to display the specific value of the angle encoder 44, so as to display the tilt angle of the first stack assembly 60 and the second stack assembly 70 in real time. Each time it is assembled, the value of the angle encoder 44 in the computing device 46 needs to be cleared. The angle encoder 44 can accurately read the rotation angle of the angle adjustment disk 41, and these read data can be processed and displayed through the amplifier 45 and the computing device 46. This ensures that high-precision angle measurement results can be obtained when adjusting the tilt angle, thereby improving the accuracy of the assembly process and effectively reducing errors caused by visual inspection or manual measurement.

[0088] In some embodiments, the skew assembly device of the motor rotor lamination assembly further includes: a base 80 having a second central through hole and a third positioning hole 81; wherein the angle adjustment disk 41 passes through the second central through hole, and the locking member 42 locks and fixes the angle adjustment disk 41 and the base 80; and the guide rod assembly 20 is also sleeved in the third positioning hole 81. Specifically, the base 80 and the angle adjustment disk 41 are clearance-matched.

[0089] In some embodiments, the base 80 further has an angle scale surrounding the angle adjustment disk 41; the angle adjustment disk 41 has an angle mark for matching with the angle scale to calculate the rotation angle of the angle adjustment disk 41. Through the angle scale and the angle mark, the tilt angle can be intuitively read and adjusted, which facilitates assembly operations.
