Description

Technical Field

[0001] This utility model relates to an electric motor assembly device, and more particularly to an electric motor rotor support device. Background Technology

[0002] In the current assembly process of medium and large-sized motors, the rotor is mainly hoisted and assembled manually. Manually hoisting the rotor is not only time-consuming and labor-intensive, but also prone to improper operation due to its weight and size, increasing the difficulty and risk of assembly. Therefore, the existing manual assembly method is not only inefficient, but also cannot fully guarantee safety, limiting further improvements in production efficiency.

[0003] Furthermore, the manual assembly process relies on the operator's experience and skill level, making it difficult to achieve standardization and consistency in the context of multi-batch, large-scale production. Therefore, to ensure the quality and performance of the motor, frequent manual adjustments and calibrations are required, increasing the assembly cycle and consequently impacting the product's market competitiveness.

[0004] To address the aforementioned issues, the applicant developed an automated motor assembly machine. As a crucial step, the rotor needs to be positioned, supported, and transported to achieve automated motor assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a motor rotor support device that is compact in structure and small in size, and can realize the support, positioning and conveying of the rotor.

[0006] This utility model provides a motor rotor support device, which includes:

[0007] The base serves as the mounting platform;

[0008] The slide block is horizontally slidably mounted on the base.

The first support block and the second support block are provided with slots with open upper ends. The axis of the slots is parallel to the sliding direction of the slide block, and the axes of the two slots are located in the same vertical plane. The first support block and / or the second support block can slide horizontally and the distance between the two slots can be adjusted.

[0010] A first driving mechanism is connected to the slide block and is used to drive the slide block to move horizontally.

[0011] The second drive mechanism is connected to the first support base and is used to drive the first support base to rise and fall.

[0013] This application features a first and second support base capable of independent lifting and lowering, allowing for individual height adjustment of the two support blocks to accommodate different rotor specifications and types, offering high flexibility. Simultaneously, the entire unit can be lowered, creating overhead clearance to prevent interference during rotor assembly and overall machine assembly, improving assembly efficiency and safety, and reducing the overall space occupied by the equipment. The groove design on the support blocks effectively encloses and confines the rotor journal, preventing lateral rolling or slippage and providing stable radial support. The coaxiality of the two groove axes within the same vertical plane ensures the coaxiality of the supports, avoiding additional stress caused by support misalignment. The slide adopts a horizontal sliding structure, enabling horizontal sliding and axial movement of the rotor, facilitating collaborative work with other stations on the assembly line and achieving continuous and automated assembly.

[0014] Furthermore, the groove is a V-shaped groove.

[0015] Furthermore, the bracket is provided with rollers on both sides, and the rotation axis of the rollers is parallel to the axis of the bracket.

[0016] Furthermore, a support plate for installing a second support block is slidably mounted on the upper end of the second support base.

A limiting block is provided on the support plate, and a fixing hole is opened on the limiting block. One or more bolts pass through the fixing hole and connect to the positioning hole on the second support base to achieve fixation. There are multiple positioning holes, which are equidistantly arranged along the sliding direction of the support plate.

[0017] Furthermore, the limiting block is disposed on the top surface of the second support base, and the upper end of the limiting block is provided with a limiting groove for the tray to be embedded and thus limited.

[0018] Furthermore, the first drive mechanism includes a rack mounted on the base and a first drive motor mounted on the slide, wherein the output end of the first drive motor is provided with a drive gear that meshes with the rack.

[0019] Furthermore, the second drive mechanism and the third drive mechanism respectively include a second drive motor, a synchronous pulley and a lead screw. The synchronous pulley is rotatably mounted on the slide block, and a nut is provided inside the synchronous pulley. The lead screw is vertically fixed to the lower end of the first support or the second support and meshes with the nut.

Detailed Implementation

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] See Figures 1-5 This utility model provides a motor rotor support device for providing stable support for the motor rotor and rotor assembly. It includes a base 261, a slide 262, a first support 263, a second support 265, a first drive mechanism 2621, a second drive mechanism 2631, and a third drive mechanism 2651.

[0031] The base 261 serves as the mounting carrier for mounting the slide 262. The slide 262 is horizontally slidably mounted on the base 261. A support assembly is mounted on the slide 262, comprising a first support seat 263 and a second support seat 265. The line connecting the first support seat 263 and the second support seat 265 is parallel to the sliding direction of the slide 262. Specifically, the first support seat 263 and the second support seat 265 are vertically slidably mounted on the slide 262 via guide rods, enabling independent lifting and lowering. A first support block 264 is provided on the top of the first support seat 263, and a second support block 266 is provided on the top of the second support seat 265. The first support block 264 and the second support block 266 have slots with open upper ends for lifting the motor rotor. In this application, the axis of the slot is parallel to the sliding direction of the slide 262, and the axes of the two slots are located in the same vertical plane to ensure the axial direction of the motor rotor. A lifting space is formed between the two slots for lifting the rotor.

[0032] The first drive mechanism 2621 is connected to the slide 262 and is used to drive the slide 262 to move horizontally; the second drive mechanism 2631 is connected to the first support 263 and is used to drive the first support 263 to rise and fall; the third drive mechanism 2651 is connected to the second support 265 and is used to drive the second support 265 to rise and fall.

[0033] This application features a first support 263 and a second support 265 capable of independent lifting and lowering, allowing for individual height adjustment of the two support blocks to adapt to the assembly requirements of rotors of different specifications and types, offering high flexibility. Simultaneously, the entire block can be lowered, creating clearance space above and preventing interference during rotor assembly and overall machine assembly, thus improving assembly efficiency and safety, and reducing the overall space occupied by the equipment. The groove design on the support blocks effectively wraps around and confines the rotor journal, preventing it from rolling or slipping, and providing stable radial support. The two groove axes being located in the same vertical plane ensures the coaxiality of the support, avoiding additional stress caused by support misalignment. The slide adopts a horizontal sliding structure, enabling horizontal sliding and axial movement of the rotor, facilitating collaborative operation with other workstations on the assembly line and achieving continuous and automated assembly.

[0034] The motor rotor support device in this application achieves precise, flexible, and automated adjustment of the rotor position through horizontal movement and independent lifting in two vertical directions. It perfectly solves the problems of supporting, aligning, leveling, and axially moving different types of rotors, providing a reliable guarantee for the efficient and coordinated operation of the rotor in the overall assembly process.

[0035] In this application, guide rod assemblies are provided on the side walls or lower ends of the first support base 263 and the second support base 265. The guide rod assemblies are vertically slidably mounted on the slide block 262, thereby enabling the lifting and lowering of the first support base 263 and the second support base 265. The guide rod assemblies consist of multiple guide rods, which are symmetrically arranged on both sides of the first support base 263 or the second support base 265 to achieve stable support and lifting and lowering of the first support base 263 and the second support base 265. A certain height space is provided at the lower end of the slide block 262 to provide space for the guide rods to move downward.

[0036] The slot in this application is a V-groove. When the cylindrical rotor journal is placed into the V-groove, under the action of gravity, the journal will naturally slide towards the bottom of the included angle of the V-groove and eventually stabilize on the center line. This greatly simplifies the operation process, quickly achieves the initial alignment of the rotor, lays a good foundation for subsequent precision leveling, and improves work efficiency. It can greatly improve the versatility of the device. Different models of motors may have different rotor journal diameters, and the V-groove, through its inclined sidewalls, can well adapt to shaft diameters that are too large or too small within a certain range, reducing equipment costs and tooling change time, and has strong dimensional adaptability. At the same time, the two inclined sides of the V-groove form a natural confining space, which can effectively prevent the rotor from axially rolling or laterally sliding under the support state, providing a stable and safe foundation for subsequent assembly operations and preventing accidents.

[0037] To reduce friction between the rotor and the mounting bracket, rollers are provided on both sides of the mounting bracket, with the rotation axis of the rollers parallel to the axis of the mounting bracket. When the rotor needs to be moved radially, the traditional V-groove and rotor journal experience sliding friction, resulting in high resistance and potential creeping. However, in this application, the roller design transforms the contact between the rotor journal and the support point into rolling friction. In the final assembly step, when aligning the mounting holes at the rotor assembly end with those at the motor housing end, the rolling action of the rollers easily enables fine-tuning of the rotor's rotation. This is convenient and labor-saving, effectively preventing damage to the rotor surface caused by sliding friction, thus improving assembly quality and efficiency. The rollers not only reduce the labor intensity of operators but also minimize equipment wear caused by excessive friction, ensuring assembly accuracy and extending the service life of the device.

[0038] In order to adapt to different specifications, in this application, the first support block 264 or the second support block 266 can be horizontally slidable, thereby adjusting the distance between the two brackets. The rotor lengths of motors of different specifications are different, and the span (distance between support points) of the bearing positions at both ends of the rotor varies greatly. An adjustable support structure is adopted, and the distance between the two support points is adjusted by sliding the support block. There is no need to replace the entire support base or prepare multiple sets of special equipment, which realizes multi-purpose use, good versatility and high flexibility.

[0039] In this embodiment, the second support block 266 adopts a sliding structure. Specifically, a support plate 268 is slidably mounted on the upper end of the second support base 265. The second support block 266 is fixedly installed on the support plate 268. The sliding direction of the support plate 268 is parallel to the sliding direction of the slide block 262. A limiting block 267 is provided on the support plate 268, and a fixing hole 2670 is provided on the limiting block 267. One or more bolts pass through the fixing hole 2670 and connect to the positioning hole 2650 on the second support base 265, thereby fixing the support plate 268. There are multiple 50 holes, equidistantly arranged along the sliding direction of the support plate 268. When adjustment is required, loosen the bolts on the limit block, adjust the position of the support plate along the sliding direction, and then tighten the bolts to fix it when the desired position is reached. By setting multiple fixing holes, the support plate can be accurately positioned at different positions, thereby adapting to the assembly requirements of rotors of different lengths. Without sacrificing rigidity, it achieves fast, reliable, and wide-range position adjustment. Although it is not fully automated, it perfectly solves the need to adjust the support distance through an extremely ingenious and simple mechanical structure.

[0040] Specifically, the limiting block 267 is set on the top surface of the second support 265, and the upper end of the limiting block 267 is provided with a limiting groove, which can accommodate the partial embedding of the tray 268, thereby achieving precise positioning of the tray 268; its structure is compact, its manufacturing cost is low, and its assembly is convenient.

[0041] In this application, the first drive mechanism 2621 includes a rack 2611 mounted on a base 261 and a first drive motor mounted on a slide 262. The length direction of the rack 2611 is parallel to the sliding direction of the slide 262. A drive gear is provided at the output end of the first drive motor. The drive gear meshes with the rack 2611. The first drive motor drives the drive gear to rotate, and the drive gear meshes with the rack, thereby driving the slide 262 to move along the length direction of the rack 2611. For the assembly of the rotor, there is no need for high precision in the axial direction. The gear and rack transmission method can meet the needs of rapid adjustment, thereby reducing the overall manufacturing cost.

[0042] In this application, both the second drive mechanism 2631 and the third drive mechanism 2651 adopt a screw and nut structure. Specifically, it includes a second drive motor, a synchronous pulley, and a screw. The synchronous pulley is rotatably mounted on the slide 262, and its rotation axis is perpendicular to the horizontal plane. A nut is provided inside the synchronous pulley. The screw is vertically fixed to the lower end of the first support 263 or the second support 265. The screw is sleeved in the nut and meshes with the nut (or is threadedly connected). By rotating the nut, the relative movement of the two on the axis can be realized. The second drive motor is connected to the synchronous pulley via a synchronous belt. Specifically, a synchronous pulley is provided at the output end of the second drive motor, and it is connected to another synchronous pulley via a synchronous belt. Finally, the vertical movement of the first support 263 or the second support 265 is realized, that is, lifting is achieved. In this embodiment, the second drive motor is a servo motor, which is used to precisely adjust the height of the first support 263 and the second support 265.

[0043] This application also includes a protective cover that can cover the timing pulley and timing belt, thereby protecting the timing pulley and timing belt, preventing foreign objects from entering, and improving the stability and reliability of use.

[0044] The motor rotor support device in this application achieves precise, flexible, and automated adjustment of the rotor position through horizontal movement and independent lifting in two vertical directions. It perfectly solves the problems of supporting, aligning, leveling, and axially moving different types of rotors, providing a reliable guarantee for the efficient and coordinated operation of the rotor in the overall assembly process.

[0045] 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.
