Description

Technical Field

[0001] This utility model relates to the field of magnetic gear composite motor assembly technology, and more specifically to a magnetic gear composite motor assembly workbench. Background Technology

[0002] The magnetic gear composite motor is a new type of mechatronic device that integrates a permanent magnet motor and a magnetic field modulated magnetic gear. It achieves non-contact torque transmission through magnetic field coupling and has significant advantages such as high torque density, low mechanical loss, maintenance-free operation, and low noise. It has broad application prospects in high-value-added fields such as new energy vehicles, precision machine tools, wind power generation, and aerospace.

[0003] A search revealed Chinese patent CN207074901U, which discloses a magnetic gear composite motor for a fan. This device adjusts the outer rotor of the magnetic gear by using a magnetic gear adjusting magnet block and the inner rotor of the magnetic gear to achieve the required torque and speed. The design is simple and can accurately supply torque and speed. However, when assembling the magnetic gear with the permanent magnet motor, it mainly relies on manual operation or general tooling fixtures. Manual force application makes it difficult to control the uniformity and straightness of the pressing process, resulting in bearing preload deviation or coaxiality deviation, which directly affects the motor life.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides a magnetic gear composite motor assembly workbench, including a workbench body 1. A fixed platform 3 is bolted to the upper surface of the workbench body 1. Side plates 5 are bolted to both sides of the upper surface of the fixed platform 3. A bidirectional lead screw 6 is rotatably connected between the two side plates 5 via bearing seats. Two symmetrical slides 7 are threaded to the bidirectional lead screw 6 via threaded sleeves. The bottom ends of the two slides 7 are bolted to clamps 8 for fixing the motor. A rear support assembly for pressing the rear of the motor is provided on the upper surface of the workbench body 1 and on one side of the fixed platform 3. Two symmetrical slide rails 4 are bolted to the upper surface of the workbench body 1 and on the other side of the fixed platform 3. A slide table 9 is slidably connected to the two slide rails 4. A vertical plate 10 is bolted to the upper surface of the slide table 9. A three-jaw chuck 11 is bolted to one side of the vertical plate 10.

[0024] When using it, first install the magnetic gear that needs to be used with the motor onto the three-jaw chuck 11. During installation, first place the magnetic gear between the multiple jaws on the three-jaw chuck 11. Then, when one of the small bevel gears is turned with a wrench, it will drive the large flat gear to rotate and mesh with the teeth on the back of the three jaws, thereby driving the three jaws to clamp towards the center at the same distance and thus fix the magnetic gear.

[0025] The slide table 9 and slide rail 4 work together to precisely guide the movement of the vertical plate 10 during the extension and retraction of the cylinder 13, thereby ensuring precise docking between the magnetic gear and the motor output shaft and further increasing the assembly precision.

[0026] Furthermore, both sides of the fixed platform 3 are fixedly connected with a set of guide rods 14 by bolts, and each set consists of two symmetrical rods. The two guide rods 14 in the same set pass through the corresponding clamps 8 and are slidably connected to the clamps 8.

[0027] Furthermore, both ends of the bidirectional lead screw 6 pass through the corresponding side plates 5 and are fixedly connected to knobs by bolts. The outer circumference of the knobs is provided with anti-slip texture.

[0028] The fixed platform 3 with clamp 8 and vertical plate 10 with three-jaw chuck 11 are used together to fix the motor and the magnetic gear to be installed on the motor, respectively. This realizes the automated positioning and docking of the motor and magnetic gear assembly process, eliminating the slight shaking and position deviation that are unavoidable when manually handled.

[0029] Then, the motor is placed on the fixed platform 3 and the bidirectional lead screw 6 is rotated. This will drive the two slides 7 to move. As the slides 7 move, the clamps 8 at their bottom ends will move along the guide rod 14. The motor is fixed as the two clamps 8 move closer to each other.

[0030] The rear support assembly of this utility model includes an L-shaped plate 15 that is fixedly connected to the upper surface of the workbench body 1 by bolts. Two symmetrical round rods 16 are slidably connected through the L-shaped plate 15, and the ends of the two round rods 16 are fixedly connected to the rear support plate 17 by bolts.

[0031] A threaded rod 18 is rotatably connected to one side of the rear support plate 17 via a bearing seat. One end of the threaded rod 18 passes through one side of the L-shaped plate 15 and is threadedly connected to the L-shaped plate 15 via a threaded sleeve.

[0032] After the motor is fixed, rotate the threaded rod 18 to move the rear support plate 17 toward the motor. After the rear support plate 17 contacts the motor, the rear end of the motor can be tightened.

[0033] The included rear support assembly can be used to press the rear of the motor firmly after it is fixed, ensuring that the motor will not shift backward during assembly and increasing assembly accuracy.

[0034] In this utility model, a fixing frame 12 is bolted to the upper surface of the workbench body 1 and located at one end of the two slide rails 4. A cylinder 13 is bolted to one side of the fixing frame 12 and one side of the vertical plate 10.

[0035] It should be noted that: Cylinder 13 is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the extension and retraction displacement of the piston rod of cylinder 13. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0036] Specifically, the starting cylinder 13 extends, and during the extension process, the vertical plate 10 pushes the slide table 9 to slide along the slide rail 4, thereby driving the magnetic gear to move towards the motor through the three-jaw chuck 11, so that the motor and the magnetic gear can be assembled.

[0037] Furthermore, a perforated plate 2 for placing tools is fixedly connected to one end of the upper surface of the workbench body 1 by bolts.

[0038] In this application, the inner wall of the threaded cylinder on the slide 7 and L-shaped plate 15 is provided with an annular groove in the axial direction. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit of 15°-20° with the surfaces of the double-acting screw 6 and the threaded rod 18, respectively. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread springback.

[0039] The use of this utility model involves the following steps:

[0040] S1: When using, first install the magnetic gear that needs to be used in combination with the motor onto the three-jaw chuck 11. During installation, first place the magnetic gear between the multiple jaws on the three-jaw chuck 11. Then, when one of the small bevel gears is turned with a wrench, it will drive the large flat gear to rotate and mesh with the teeth on the back of the three jaws, thereby driving the three jaws to clamp towards the center at the same distance and thus fix the magnetic gear.

[0041] S2: Then place the motor on the fixed platform 3 and rotate the double-acting screw 6. This will drive the two slides 7 to move. While the slides 7 are moving, the clamps 8 at their bottom ends will move along the guide rod 14. The motor is fixed as the two clamps 8 approach each other.

[0042] S3: After the motor is fixed, rotate the threaded rod 18 to move the rear support plate 17 toward the motor. After the rear support plate 17 contacts the motor, the rear end of the motor can be tightened.

[0043] S4: Then the cylinder 13 is activated to extend. During the extension of the cylinder 13, the slide table 9 is pushed along the slide rail 4 by the vertical plate 10, thereby driving the magnetic gear to move towards the motor through the three-jaw chuck 11, so that the motor and the magnetic gear are assembled.

[0044] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0045] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0046] The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
