Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a large motor stator and rotor loading and unloading platform. Background Technology

[0002] In traditional large-scale motor stator and rotor loading and unloading operations, simple mechanical devices or manual methods are typically used for the loading, unloading, and positioning of the rotor and stator. Traditional device structures mainly include a fixed base, a slide table adjustable in one direction, and a simple clamping mechanism. The rotor is usually fixed and hoisted using clamps and lifting structures, while the stator is aligned manually or with simple support structures. While this method can accomplish the loading and unloading work to a certain extent, it still has many shortcomings in actual operation.

[0003] First, traditional equipment lacks multi-axis adjustment capabilities in its structural design, relying solely on fixed slides and clamping mechanisms to load and unload the rotor and stator. This means the equipment cannot achieve synchronous positioning and coaxial alignment of the stator and rotor. During loading and unloading, frequent adjustments to the rotor and stator positions are required, making the operation complex and time-consuming, severely impacting work efficiency. Furthermore, traditional equipment has a low overall level of automation, with most operations relying on manual labor. This not only increases labor intensity but also makes it prone to assembly defects due to human error, affecting product quality and efficiency.

[0004] In view of this, we have studied and improved the existing problems to provide a large motor stator and rotor loading and unloading platform to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] This utility model relates to a large motor stator and rotor loading and unloading platform, specifically to a device for the precise loading, unloading, alignment and assembly of large motor stators and rotors, belonging to the field of motor equipment assembly technology.

[0006] This invention aims to solve the problems of low efficiency in the assembly and disassembly of motor stators and rotors, poor alignment accuracy, and complex operation in existing technologies. Traditional devices lack multi-axis adjustment functions, making it impossible to achieve synchronous positioning and coaxial alignment of the rotor and stator. Furthermore, frequent manual adjustments are required during assembly and disassembly, resulting in low assembly accuracy. In addition, the magnetic force of the stator interferes with the assembly and disassembly of the rotor, further affecting assembly quality and efficiency.

[0007] To address this, the present invention provides a large motor stator and rotor loading and unloading platform, which achieves precise positioning and stable clamping of the rotor and stator through structural optimization, significantly improving loading and unloading efficiency and assembly quality.

[0008] This utility model includes a base, a separating slide rail, a slide table base, an adjusting rail platform, a rotor tooling base, and a stator tooling assembly. The rotor tooling base is fixedly installed at one end of the base, and its surface is equipped with horizontally arranged clamping shafts and jaws for precise positioning and stable clamping of the motor rotor. A separating slide rail is fixedly installed on the surface of the base, a slide table base is slidably installed on the separating slide rail, and an adjusting rail platform is slidably installed on the surface of the slide table base for multi-axis adjustment of the stator tooling assembly.

[0009] The stator tooling assembly includes a fixed base, a positioning sleeve, and radially adjustable positioning ears. The positioning sleeve has a C-shaped notch structure for easy insertion of the stator, and the radial synchronous movement of multiple positioning ears clamps and centers the stator, making the stator alignment more precise during assembly. The driving mechanism of the positioning ears can be either screw-driven or hydraulically driven, adaptable to manual adjustment and automated operation. Several positioning ears are evenly distributed circumferentially on the surface of the positioning sleeve. The surfaces of the separating slide rails are each equipped with a screw drive assembly, used for position adjustment of the slide base and the adjusting rail, respectively. The input end of the screw drive assembly is electrically connected to a controller.

[0010] Preferably, the separation slide rail on the platform surface is arranged at an angle and parallel to the axial direction of the clamping disc shaft, and the lead screw drive assembly on the separation slide rail surface is arranged parallel to the axial direction of the clamping disc shaft.

[0011] Preferably, the lead screw drive assembly on the slide table surface is arranged axially perpendicular to the clamping disc shaft and parallel to the sliding direction of the adjustment table.

[0012] Preferably, the positioning sleeve is a C-shaped notch assembly, with one end notch for stator mounting, and the inner side of the chuck shaft is provided with a sleeve hole for motor rotor shaft fitting.

[0013] Preferably, the surface of the positioning sleeve is provided with a driving element for driving the radial movement of the positioning ear, and the driving element is selected from either a screw or a hydraulic drive rod.

[0014] Preferably, there are two sets of positioning sleeves arranged parallel to each other on the surface of the fixed seat. The surface of the fixed seat is provided with an adjusting groove for guiding the sliding of the positioning sleeve. A bidirectional lead screw is rotatably installed on the surface of the adjusting groove. The bottom surface of the positioning sleeve is provided with a screw hole that fits into the surface of the bidirectional lead screw. The threads on the surface of the bidirectional lead screw are symmetrically arranged about the midpoint of the bidirectional lead screw and have opposite directions of rotation.

[0015] Through the above design, this utility model can efficiently complete the loading and unloading of the stator and rotor, and ensure their coaxial alignment, effectively avoiding interference from the stator's magnetic force on the rotor assembly. The multi-axis adjustment function of the slide rail, slide table base, and adjustment platform improves the adaptability of the device, which can be adapted to motor stators and rotors of different specifications, significantly improving loading and unloading efficiency and assembly accuracy.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. In this invention, the chuck shaft and its jaws installed on the rotor tooling base enable precise positioning and stable clamping of the motor rotor. The stator is fitted into the notch on the surface of the positioning sleeve and clamped using the radial synchronous movement of multiple positioning ears, resulting in a fast and efficient loading and unloading process. Through the coordinated action of the chuck shaft and jaws on the rotor tooling base, as well as the stator positioning sleeve and positioning ears, center alignment of the two components is ensured during loading and unloading, reducing adjustment steps and improving work efficiency.

[0018] In this invention, multiple lead screw drive components are used to achieve multi-axis adjustment of the stator tooling assembly. The device achieves coaxial control of the rotor tooling base and the stator tooling assembly by synchronously positioning and clamping the stator and rotor, which can ensure the precise alignment of the two during the assembly process, effectively avoid the interference of stator magnetic force on rotor assembly, and improve the overall assembly efficiency and quality.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of a large motor stator and rotor loading and unloading platform provided by this utility model. Example 1

[0030] like Figures 1 to 4 As shown, this utility model provides a large motor stator and rotor loading and unloading platform, including a platform 100, a separating slide rail 110, a slide table 120, an adjusting rail 130, a rotor tooling seat 200, and a stator tooling assembly 300.

[0031] The platform 100 has a fixedly mounted separation slide rail 110, a sliding table 120 is slidably mounted on the surface of the separation slide rail 110, and an adjusting table 130 is further slidably mounted on the surface of the sliding table 120. This structure enables multi-axis adjustment of the stator tooling assembly 300 to accommodate motor stators of different sizes.

[0032] The rotor fixture 200 is fixedly installed at one end of the base 100, and its surface is provided with a horizontally arranged clamping shaft 210, on which jaws 211 are installed. In use, the shaft end of the motor rotor can be sleeved on the inner side of the clamping shaft 210 and clamped and fixed by the jaws 211, ensuring that the rotor has good stability and accuracy during loading, unloading and positioning.

[0033] The stator tooling assembly 300 includes a fixed base 310, a positioning sleeve 320, and positioning ears 330. The positioning sleeve 320 has a C-shaped notch structure, with one end notched to facilitate quick loading and unloading of the stator. The positioning ears 330 are evenly distributed along the circumference of the positioning sleeve 320, and there are three or more of them. The positioning ears 330 achieve radial synchronous movement through a drive mechanism, used for clamping and centering the stator. The drive mechanism can be a screw or a hydraulic drive rod; the screw drive is suitable for manual adjustment, while the hydraulic drive rod is suitable for automated operation, improving the applicability and ease of operation of the equipment. Example 2

[0034] In this embodiment, the surface of the slide base 120 is provided with an adjustment rail 130. The adjustment rail 130 is position-adjustable by a motor drive device 140 to control the movement range of the stator tooling assembly 300 in multiple axes. By setting a bidirectional lead screw 312 and a slide rail groove 311, the synchronous opposite or opposite movement of the two sets of positioning sleeves 320 within the stator tooling assembly 300 can be achieved.

[0035] When loading and unloading motor stators of different specifications, the distance between the two sets of positioning sleeves 320 can be adjusted by the reverse thread structure of the bidirectional lead screw 312 to accommodate different stator lengths. After the stator is fitted into the inner side of the positioning sleeve 320 through the stator notch, multiple positioning ears 330 move radially synchronously to clamp the stator, thereby achieving precise positioning and stable clamping of the stator and avoiding interference of the stator's magnetic force on the rotor. Example 3

[0036] To enhance the automation level of the device, in this embodiment, the clamping shaft 210, the gripper 211, and the positioning ear 330 are all electrically connected to the controller. The controller controls the movement of the slide base 120 and the adjusting rail 130 through the motor drive device 140, and simultaneously realizes the radial clamping action of the positioning ear 330 through the hydraulic drive mechanism.

[0037] The specific usage process is as follows:

[0038] Insert the shaft end of the motor rotor into the inner side of the clamping disc shaft 210, clamp and fix the rotor by the jaws 211, and adjust the clamping force to ensure that the center of the rotor is aligned.

[0039] The stator is quickly inserted into the inner side of the positioning sleeve 320 through the C-shaped notch of the positioning sleeve 320;

[0040] The drive mechanism controls the radial synchronous movement of multiple positioning ears 330 to clamp and center the stator;

[0041] Adjust the positions of the slide block 120 and the adjustment rail 130 to achieve precise coaxial alignment of the stator and rotor;

[0042] Complete the loading and unloading of the stator and rotor.

[0043] Through the above implementation methods, this invention can efficiently and accurately complete the loading and unloading of motor stators and rotors. The multi-axis adjustment structure is adaptable to stators and rotors of different specifications, and the synchronous radial movement of the positioning ears achieves stable clamping of the stator. Combined with the automated operation of the controller, it significantly improves loading and unloading efficiency and assembly accuracy. All components are modularly designed, easy to maintain and replace, and suitable for long-term industrial applications.

[0044] The above are merely preferred embodiments of this utility model. Other improvements based on the concept of this utility model should be within the scope of protection of this patent.
