Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to a motor assembly tool. Background Art

[0002] As one of the core areas of modern industry, the motor manufacturing industry involves multiple key industries such as electricity, automation, transportation, and household appliances, providing strong support for sustained economic growth and industrial upgrading. With the rapid development of intelligent manufacturing technology, motor manufacturing companies are gradually shifting to digital, automated, and intelligent production methods to improve production efficiency and product quality. However, during this transformation process, some technical and operational problems have gradually emerged.

[0003] For permanent magnet motors, their rotors are composed of a large number of permanent magnets and an iron core, and have a strong magnetic attraction. During the assembly of the stator and rotor, the rotor is large in size and has a strong surface magnetic force, which makes it easy for it to attract and collide with the base and the iron core. The traditional solution that relies on the operator to hold the rotor by hand may not only damage the motor windings, but also cause harm to the operator. In severe cases, when the stator and rotor do not reach the specified position after being attracted, they may even need to be forced in with the help of large hydraulic presses and other equipment, which not only increases the difficulty of operation, but may also cause further damage to the motor.

[0004] In addition, the existing motor assembly method directly applies force to press the rotor after inserting it into the rotor positioning cavity in the center of the stator. Since the rotor is fixed on the shaft and has strong magnetism, it is easy to rotate or shift during the installation process, resulting in eccentric misalignment of the motor. This eccentric misalignment makes it impossible to ensure the alignment of the stator and rotor assembly, and the motor is prone to abnormal noise when rotating at high speed, which seriously affects its service life.

[0005] It is worth mentioning that the maintenance and environmental issues in the electric assembly process are becoming increasingly prominent. Due to the complexity and precision of the internal structure of the motor, once a failure or damage occurs, it becomes very difficult to repair and replace parts. This not only increases maintenance costs, but may also further damage the motor due to improper maintenance.

[0006] The motors of existing designs have the following disadvantages:

[0007] 1. The existing motor assembly tooling is only designed for specific models or categories of products and cannot be interoperable or work in conjunction with other products of different specifications or systems. This limitation limits the scope of use of the design to a certain extent.

[0008] 2. The driving power of the existing design is electricity. In the event of a power outage or short circuit, maintenance and replacement of parts will be very difficult, and the motor may be damaged due to improper maintenance; the use of electricity can easily cause a waste of resources and increase the cost of assembly.

[0009] 3. When using the equipment, the staff needs to be highly professional, and assembly problems may easily occur due to improper staff training. Utility Model Content

[0050] The upper platform 2 is provided with a limiting hole for the worm screw lift 1, and the two are matched in a clearance fit.

[0051] The support seat fixing block 18 and the adjustment support block 17 are matched in a clearance fit, and grease needs to be added during use.

[0052] The support plate 5 is provided with limiting holes for the worm screw lift b33 and the motor stator support plate 16, and the matching type is clearance matching.

[0053] The elastic regulator housing 23 in the elastic regulator 14 has a notch that cooperates with the rotor limit adjustment block 24. The rotor limit adjustment block 24 is limited by the notch, and the two are matched in a clearance fit. Lubricating grease needs to be added to the inside when in use.

[0054] The rotor limit adjustment block 24 and the magnetized rotor assembly 26 are matched in a clearance fit, and the limit adjustment block 24 is designed and matched according to different types of motors.

[0055] The rotor fixing support block 29 has the same function as the rotor limit adjustment block 24 and is designed and matched for different types of motors.

[0056] The two worm gear screw lifts 1 are placed symmetrically, and under the transmission of the synchronous belt, the movement direction of the second screw is consistent.

[0057] The compatible holes and through holes are both provided with guide chamfers.

[0058] The method for using the worm gear motor assembly tool comprises the following steps:

[0059] After selecting the motor to be assembled, design and process the support plate 5, the rotor limit adjustment block 24, and the rotor fixed support block 29 according to the characteristics of the motor stator assembly 27 and the magnetized rotor assembly 26;

[0060] Assemble the specially processed support plate 5, rotor limit adjustment block 24, and rotor fixed support block 29 respectively above the support plate 5, inside the elastic adjuster 14, and above the second screw of the worm gear screw lift b33;

[0061] Before assembling the motor, assemble the front end cover 15, bearing 25, magnetized rotor assembly 26, etc. of the motor into a combined part on the outside; rotate the rocker by manpower to increase the distance between the two second screw rods to avoid interference when inserting the motor stator assembly 27;

[0062] Assemble the motor stator assembly 27 above the support plate 5, and put the wave washer 30 into the bearing iron ring of the motor stator assembly 27;

[0063] The second rocker 31 is shaken to drive the worm gear screw lifter b33 to move, so that the second screw moves upward to the top of the motor stator assembly 27; the upper first rocker 3 is rotated to drive the worm gear screw lifter a1 to move, so that the second screw moves upward, and the distance between the two second screws is adjusted to avoid interference when assembling the rotor assembly;

[0064] The height of the support seat fixing block 18 is adjusted according to the size of the motor stator assembly 27. The third rocker 32 in the clamping mechanism is rotated manually to make the second screw rod approach the motor stator assembly 27. During the approaching process, the housing fixing clamping block 28 needs to be adjusted so that the motor stator assembly 27 can be evenly stressed. When clamping, the top screw above the screw rod support seat is locked to prevent loosening, which may cause errors when the motor is assembled, such as Figure 6 As shown;

[0065] Assemble the assembled rotor assembly to the rotor fixed support block 29. Since the fixed support block 29 and the magnetized rotor assembly 26 are matched with the stopper, the magnetized rotor assembly 26 will stand stably on the rotor fixed support block 29 without additional manual support.

[0066] Rotate the first rocker 3 to move the worm screw lifter a1, so that the elastic regulator 14 is assembled above the magnetized rotor assembly 26, and the elastic regulator 14 is completely attached to the assembly surface of the motor front end cover 15 through the stop fitting;

[0067] Since the elastic regulator 14 is internally provided with a disc spring 22, the upper first rocker 3 can be additionally rotated to make the elastic regulator 14 move downward. At this time, the disc spring 22 is compressed, and a certain pre-tightening force is applied to the rotor assembly. In addition, under the condition that the worm wheel in the worm screw elevator is not easy to drive the worm, the rotor assembly is stably placed above the second screw rod, so as to achieve the purpose of limiting and prevent the magnetized rotor assembly 26 from being affected by the magnetic pulling force during the assembly process.

[0068] Assemble the synchronous belt 7 onto the two synchronous wheels 8, and rotate the rocker 3 to make the magnetized rotor assembly 26 move closer to the motor stator assembly 27 until the motor front cover 15 and the motor stator assembly 27 are fully matched. After the pressing is completed, the operator screws the bolts into the installation holes.

[0069] Connect the motor end cover 15 to the motor stator assembly 2 firmly;

[0070] Remove the synchronous belt 7 above the two synchronous wheels 8, rotate the first rocker 3 above to separate the elastic regulator 14 from the magnetized rotor assembly 26, and adjust the distance between the two;

[0071] Since the rotor fixing support block 29 and the magnetized rotor assembly 26 are clearance-fitted, the assembled motor can be easily taken out manually;

[0072] Reassemble the new motor and repeat the above steps.

[0073] Working principle of the present invention:

[0074] When the present invention is in use, the operator first connects the magnetized rotor assembly 26 and the two bearings 25 to the motor shaft in sequence to form a rotor assembly, and then respectively places the rotor assembly, the corrugated washer 30, the motor end cover 15, and the motor stator assembly 27 on the integrated machine, and then uses the pressing action of the integrated machine to press and form each part and accurately position it. Since each part is pressed and formed once by the worm screw lift a1 and the elastic adjuster 14 during the pressing process, on the one hand, the installation error caused by multiple positioning of the motor can be effectively avoided, and on the other hand, the overall pressing method can also avoid the deviation of the parts and improve the pressing effect of the motor. On the basis of the above, the present invention further optimizes the height positioning structure of the motor, so that the structural components are less and the operation is simple and convenient, so that each part can be in the accurate installation position during pressing, and the deformation and damage of the motor caused by excessive pressing can be avoided.

[0075] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
