Abstract
Description
Technical Field
[0001] This utility model relates to a motor assembly machine, belonging to the field of automatic motor assembly technology. Background Technology
[0002] After the stator and rotor of the motor are manufactured, they need to be assembled to enable the motor to function properly. During assembly, precise alignment and gap control are crucial to prevent excessive air gaps from reducing magnetic flux and thus lowering motor efficiency. Traditional manual assembly methods are prone to assembly errors, which not only affect motor efficiency and lead to defective products, but may also damage the insulation layer, causing short circuits or electrical faults. To reduce manual workload and improve motor assembly efficiency, a simple structure is needed to assist in the motor assembly process. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a motor assembly machine to simplify the manual assembly workload, assist in the pre-fixing and automatic assembly of the stator and rotor of the motor, improve the assembly effect of the stator and rotor, and reduce the product defect rate.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] This utility model provides a motor assembly machine, including a base and a first sliding bracket disposed above the base. The base is provided with a stator placement platform, and a lifting mechanism that can pass through the stator placement platform from below is provided below the base. A clamping device for fixing the stator is also provided above the base. A first mounting plate is slidably disposed on the first sliding bracket in the vertical direction. A first driving device for driving the first mounting plate to rise and fall is installed on the first sliding bracket. A rotor positioning mechanism is installed on the first mounting plate.
[0006] Specifically, the lifting mechanism includes a second sliding bracket and a second mounting plate that slides vertically on the second sliding bracket. The second sliding bracket is provided with a second driving device for driving the second sliding bracket to rise and fall. The second mounting plate is provided with a push-out rod that can pass through the placement platform. The front end of the push-out rod is provided with a shaft end fixing sleeve.
[0007] Specifically, the clamping device is provided in multiple sets and is distributed around the periphery of the customized placement platform. Each set of the clamping device includes a vertical rod, on which a clamping claw is rotatably mounted. The platform is provided with multiple hydraulic cylinders for driving the corresponding clamping claw to rotate and open.
[0008] Specifically, the end of the gripper closest to the stator is configured in a "U" shape.
[0009] Specifically, the first mounting plate is provided with a positioning mechanism, which is used to fix the angle of the rotor.
[0010] Specifically, there are no fewer than two positioning mechanisms. Each positioning mechanism includes an adjusting cylinder and a clamping plate disposed at the output end of the cylinder. The multiple clamping plates can press against each other to form a clamping force on the rotor, thereby fixing the angle of the rotor.
[0011] Specifically, an elastic pull wire is provided above the first sliding bracket, and a wire clamp is provided at the lower end of the elastic pull wire.
[0012] Specifically, the first mounting plate is provided with multiple through-holes or irregularly shaped cutouts, which are used to expose the position of the locking screws where the rotor is located.
[0013] Specifically, the rotor positioning mechanism includes a pressure plate, and a top rod with a downward-pointing tip is provided in the middle of the pressure plate.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0015] This invention utilizes a lifting mechanism and a rotor positioning mechanism designed on a pedestal that allow for relative vertical movement. This enables convenient manual placement of the stator and rotor. After the rotor is placed, the upper and lower ends are simultaneously clamped and fixed, and the rotor is lowered and moved as a whole to place it into the stator. The positioning effect is more stable than manual placement, eliminating the need for manual handling of the rotor and simplifying the manual operation. This facilitates fast, efficient, and low-error-rate assembly of the stator and rotor. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example
[0029] This utility model provides a motor assembly machine to simplify manual assembly work. It assists in the pre-fixing and automatic assembly of the motor's stator and rotor, improving assembly efficiency and reducing product defect rates. To achieve the machine's structural functions, it includes a base 1 and a first sliding bracket 5 positioned above the base 1. A stator placement platform 2 is provided on the base 1 for positioning and placing the stator. The shape and size of the stator placement platform 2 can be flexibly changed according to the type of motor to be assembled. Preferably, the stator placement platform 2 has corresponding positioning openings or anti-fooling openings to prevent operators from mistakenly assembling the motor stator. To improve the accuracy of stator placement and ensure the stability of the assembly process, preventing stator deviation, a clamping device 4 for fixing the stator can be installed above the platform 1. To enable automatic clamping and assembly of the rotor, a lifting mechanism 3 is provided below the platform 1, extending from the bottom of the stator placement platform 2. This allows manual placement of the rotor at the lifting end of the lifting mechanism 3. To fix the rotor and facilitate its assembly with the stator, a first mounting plate 6 is slidably mounted vertically on the first sliding bracket 5, such as using a sliding rod assembly method. Figure 1 and Figure 3As shown, a first driving device 9 for driving the first mounting plate 6 to rise and fall is installed on the first sliding bracket 5. The first driving device 9 can be a motor or cylinder, etc., capable of achieving its position lifting function. A rotor positioning mechanism 7 is installed on the first mounting plate 6. With the above structural design, when it is necessary to assemble the stator and rotor, the stator is first placed on the placement platform 2 and then clamped. After the clamping action is completed, the lifting mechanism 3 pushes out the positioning point of the exposed tip, and the rotor is placed on the positioning point of the lifting mechanism 3. Then, the first mounting plate 6 drives the rotor positioning mechanism 7 to fall, thereby clamping the rotor. After the rotor is clamped, the first mounting plate 6 and the lifting mechanism 3 simultaneously perform the descent action. The assembly of the stator and rotor can be achieved with manual assistance. The concentric point is less likely to be misaligned, and the assembly is less likely to cause collision and wear, which helps to ensure the assembly effect of the stator and rotor. At the same time, it simplifies manual labor and helps to reduce the product defect rate.
[0030] This utility model provides a motor assembly machine, specifically offering a lifting mechanism 3 configuration. Specifically, the lifting mechanism 3 includes a second sliding bracket 301 and a second mounting plate 302 slidably mounted on the second sliding bracket 301 in a vertical direction. Figure 4 as well as Figure 6 As shown, sliding assembly can be achieved using guide rods. A second drive device 303 is provided on the second sliding bracket 301 to drive its lifting and lowering. The second drive device 303 controls the lifting and lowering of the second mounting plate 302. To allow the rotor to be placed through the stator, an ejector rod 304 is installed on the second mounting plate 302, which can extend from the placement platform 2. The ejector rod 304 achieves concentric positioning of the rotor body shaft end. A shaft end fixing sleeve is provided at the front end of the ejector rod 304 to further prevent possible axial misalignment of the rotor. Similarly, the rotor positioning mechanism 7 may include a pressure plate 701. A downward-pointing ejector rod 702 is provided in the middle of the pressure plate 701 to ensure the stability of the axial positioning of the upper end of the rotor. In the above driving method, it is preferable to use a motor to drive a lead screw for transmission. Since this is prior art, it will not be described in detail here.
[0031] This utility model provides a motor assembly machine, specifically a clamping device 4 to improve the stability of the motor stator during placement and assembly operations. Specifically, multiple sets of clamping devices 4 can be provided and distributed around the stator placement platform 2, each set of clamping devices 4 including a vertical rod 401, such as... Figure 2 As shown, a gripper 402 is rotatably mounted on the upright 401, and as... Figure 7As shown, the platform 1 is equipped with multiple hydraulic cylinders 403 for driving the corresponding grippers 402 to rotate and open. By controlling the extension and retraction of the hydraulic cylinders 403, the grippers 402 are driven to rotate and open or close. Note that when manually placing the stator, the grippers 402 should gradually change from the open state to the closed state, requiring manual assistance to pull the hand out. Sufficient space can be reserved around the perimeter of the platform 2 for pulling out. In order to clamp the stator housing of some specific models of motors, the end of the gripper 402 near the stator can be set as a "U" shape. The "U" shape design can effectively clamp the motor housing and prevent the stator from deviating.
[0032] This utility model provides a motor assembly machine. To ensure the assembly effect of the rotor, a positioning mechanism 8 is specifically provided on the first mounting plate 6. The positioning mechanism 8 is used to fix the angle of the rotor to prevent the rotor from deviating in its axial direction, thereby further reducing the impact of the air gap on the motor operation. Specifically, at least two positioning mechanisms 8 can be provided, and each positioning mechanism 8 includes an adjusting cylinder and a clamping plate provided at the output end of the cylinder. Multiple clamping plates can press against each other to form a clamping force on the rotor, thereby fixing the angle (axial deflection angle) of the rotor. Other optional implementation methods are not further limited here.
[0033] This utility model provides a motor assembly machine. Considering that some stators and rotors need to have their brake wires led out during assembly to facilitate the normal connection of external wiring to the brake function, and in order to adapt the brake wires to the automatic assembly operation, an elastic pull wire (such as a rubber strip or other elastic material) can be provided above the first sliding bracket 5. By providing a wire clamp at the lower end of the elastic pull wire, the brake wires are clamped during assembly and led out during the rotor descent assembly process to ensure their normal connection to the external circuit.
[0034] This utility model provides a motor assembly machine. After the stator and rotor are assembled, the screws need to be tightened to form a stable fixation of the stator and rotor. If the first mounting plate 6 is removed at this time, it may cause the rotor to deflect, resulting in inaccurate assembly failure. Therefore, multiple through-holes or irregularly shaped cutouts are directly provided on the first mounting plate 6 to expose the position of the screws where the rotor is located. Then, manual tightening can be performed. The operation is convenient and simple, and it is beneficial to use it in a variety of different stator and rotor assembly operations.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
