Description

Technical Field

[0001] This utility model belongs to the technical field of automated equipment for motor manufacturing, and in particular relates to an automatic embedding and positioning fixture for motor rotors. Background Technology

[0002] With the rapid development of modern industry, electric motors, as an important power source, are widely used in various fields. In the manufacturing process of electric motors, the precise installation and positioning of the rotor is a key factor that determines the performance and quality of the motor. Especially in mass production, how to efficiently and accurately embed the motor rotor into the stator or other related workpieces and ensure that it is in the correct spatial position has become an important challenge for the motor manufacturing industry.

[0003] Currently, the embedding and positioning of motor rotors largely relies on manual operation or semi-automated equipment. Traditional manual operation methods are often affected by the operator's experience, fatigue level, and different operating habits, which makes it difficult to guarantee the consistency of embedding depth and rotation angle, thus affecting the final quality of the product. At the same time, manual operation is inefficient and cannot meet the speed and capacity requirements of modern production lines.

[0004] To improve production efficiency and product quality, the industry has developed some semi-automated tooling. However, these toolings are usually limited in function, either only capable of simple embedding or limited positioning adjustments. When multi-angle, high-precision rotational positioning of the rotor is required, existing tooling often requires frequent manual intervention or complex adjustment steps, which not only increases the difficulty of operation but also limits the improvement of automation. Furthermore, existing tooling generally has poor adaptability to different models and sizes of motor rotors, often requiring customized special fixtures, leading to increased equipment costs and reduced changeover efficiency. Therefore, designing an automated tooling that can achieve automatic and precise embedding of motor rotors, perform multi-angle, high-precision rotational positioning, and possess good compatibility is a pressing technical challenge in the current motor manufacturing field.

[0005] Therefore, this utility model proposes an automatic embedding and positioning fixture for motor rotors to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automatic motor rotor embedding and positioning fixture, which aims to improve the problems of low automation, insufficient positioning accuracy and poor compatibility with rotors of different sizes in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic motor rotor embedding and positioning fixture, comprising a base, a mounting frame, a lifting rod, a top box; and a rotating mechanism and a clamping mechanism;

[0008] The rotating mechanism includes a motor fixedly connected inside the top box. The motor's output end is fixedly connected to both a first gear and a transmission rod. The first gear meshes with a second gear. The bottom of the transmission rod is fixedly connected to the second gear. The transmission rod drives the rotating block to rotate via the second gear. The tail of the rotating block is connected to the second gear and slidably connected to a groove inside the rotating disk. The clamping mechanism includes a mounting plate fixedly connected to the bottom of the rotating disk. A cylinder is fixedly mounted inside the mounting plate.

[0009] Furthermore, a mounting bracket is fixedly installed on the top of the base, a lifting rod is fixedly connected to the top of the base, and a top box is fixedly connected to the top of the lifting rod; a rotating mechanism and a clamping mechanism are installed at the bottom of the top box. Precise rotation of the rotating mechanism is achieved through gear transmission and sliding engagement driven by a motor; adaptive clamping of the clamping mechanism is achieved through the linkage of connecting rods, rotating rods, and clamping blocks driven by a cylinder. These components are combined through specific fixed connections, meshing connections, sliding connections, and rotating connections, collectively constituting the core function of the automatic motor rotor embedding and positioning fixture.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-7 This utility model provides an embodiment of an automatic motor rotor embedding and positioning fixture, comprising a base 1, a mounting frame 4 fixedly mounted on the top of the base 1, a lifting rod 2 fixedly connected to the top of the base 1, and a top box 3 fixedly connected to the top of the lifting rod 2. The base 1 serves as the mounting base for the entire device, used to place and fix the fixture. The lifting rod 2 is used to realize the overall lifting movement of the fixture, while the top box 3 serves as a carrier for the core functional components, rising and falling with the lifting rod 2.

[0032] A rotating mechanism 5 and a clamping mechanism 6 are installed at the bottom of the top box 3. The rotating mechanism 5 includes a motor 501, which is fixedly connected inside the top box 3. The output end of the motor 501 is fixedly connected to both a first gear 502 and a transmission rod 503. The first gear 502 meshes with a second gear 504. The bottom of the transmission rod 503 is fixedly connected to the second gear 504, and the transmission rod 503 drives the rotating block 505 to rotate through the second gear 504. The tail of the rotating block 505 is connected to the second gear 504, and the tail of the rotating block 505 is slidably connected to a groove 507 inside the rotating disk 506. The ingenious design of the rotating mechanism 5 allows the rotational motion of the motor 501 to be transmitted through gears and connecting rods, ultimately transforming into the precise rotation of the rotating disk 506. This enables the positioning and rotation of the rotor 7 clamped by the clamping mechanism 6. The sliding connection of the rotating block 505 within the groove 507 ensures that the rotating disk 506 maintains stable drive and positioning during rotation.

[0033] The clamping mechanism 6 includes a mounting plate 601, which is fixedly connected to the bottom of the rotating disk 506. A cylinder 602 is fixedly mounted inside the mounting plate 601. A connecting rod 603 is fixedly connected to the output end of the cylinder 602, and a rotating rod 604 is rotatably connected to the outside of the connecting rod 603. A connecting column 605 is fixedly connected to the rotating rod 604, and a connecting block 606 is fixedly connected to the side wall of the connecting column 605. The connecting block 606 is fixedly connected to a clamping block 607. The clamping block 607 is used to clamp the rotor 7. The clamping mechanism 6 drives the connecting rod 603 through the linear reciprocating motion of the cylinder 602, and then, through the rotating rod 604, connecting column 605, and connecting block 606, the clamping block 607 achieves opening and closing motion, thereby reliably clamping and releasing rotors 7 of different sizes. This design ensures the automation of the clamping process and the stable fixation of the rotor 7.

[0034] The system also includes a rotating mechanism 5. A motor 501 in the rotating mechanism 5 is fixedly connected to the inside of the top box 3. The output end of the motor 501 is fixedly connected to the first gear 502, and also fixedly connected to the transmission rod 503. The first gear 502 meshes with a second gear 504. The bottom of the transmission rod 503 is fixedly connected below the second gear 504. The transmission rod 503 drives the rotating block 505 to rotate via the second gear 504. The tail of the rotating block 505 is connected to the second gear 504, and the tail of the rotating block 505 is slidably connected to a groove 507 inside the rotating disk 506. This connection method allows the rotational motion of the motor 501 to be precisely transmitted to the rotating disk 506, thereby driving the rotation of the rotating disk 506. A mounting plate 601 of a clamping mechanism 6 is fixedly connected to the bottom of the rotating disk 506. A cylinder 602 is fixedly mounted on the mounting plate 601, ensuring that the clamping mechanism 6 and the clamped rotor 7 rotate together when the rotating disk 506 rotates.

[0035] Meanwhile, a connecting rod 603 is fixedly connected to the output end of the cylinder 602 on the clamping mechanism 6. A rotating rod 604 is rotatably connected to the outside of the connecting rod 603. A connecting column 605 is fixedly connected to the rotating rod 604. A connecting block 606 is fixedly connected to the side wall of the connecting column 605. The connecting block 606 is fixedly connected to the clamping block 607. The clamping block 607 is used to clamp the rotor 7. The reciprocating motion of the cylinder 602 drives the rotation of the rotating rod 604 through the connecting rod 603, thereby driving the connecting column 605, the connecting block 606, and the clamping block 607 to achieve the function of clamping and releasing the rotor 7. The connecting rod 603 and the rotating rod 604 are rotatably connected by a pin shaft, which ensures the smoothness and reliability of the motion, so that the clamping mechanism 6 can adapt to rotors 7 of different sizes and achieve fast and accurate clamping and release.

[0036] For the power source used to drive the lifting rod 2 to achieve lifting, those skilled in the art can use a variety of conventional methods such as motors and cylinders. The specific internal structure is a well-known technology in the field and will not be described in detail here.

[0037] Both the first gear 502 and the second gear 504 are spur gears. Spur gears have the advantages of simple structure, smooth transmission, and easy manufacturing, making them very suitable for achieving accurate torque transmission and speed conversion in this tooling, reducing impact and noise during transmission, thereby improving positioning accuracy. To ensure the stability and positioning accuracy of the sliding block 505 inside the rotating disk 506, a groove 507 is formed along the radial direction of the rotating disk 506. The radially formed groove allows the rotating block 505 to be finely adjusted or adapted in the radial direction while the rotating disk 506 rotates, ensuring that the rotating block 505 and the groove 507 always maintain a good fit, thereby precisely controlling the rotation angle of the rotating disk 506.

[0038] To reliably and non-destructively clamp rotors 7 of different diameters, the inner side of the clamping block 607 is provided with an arc-shaped clamping surface, which is adapted to the shape of the outer circular surface of the rotor 7. This arc-shaped design can increase the contact area between the clamping block 607 and the rotor 7, avoid damage to the surface of the rotor 7, and adapt to a certain range of rotor diameter changes, thereby improving the versatility and stability of clamping.

[0039] The connecting rod 603 and the rotating rod 604 are rotatably connected by a pin. Pin connection is a common type of rotary connection. It has a simple structure, is easy to assemble, and can provide reliable rotational freedom, ensuring that the linear motion of the cylinder 602 can be effectively converted into the rotation of the rotating rod 604, thereby realizing the opening and closing action of the clamping block 607.

[0040] The connecting column 605 extends along the axial direction of the rotating rod 604, and the connecting block 606 is located at one axial end of the connecting column 605. This structural design allows the connecting column 605, as an extension of the rotating rod 604, to stably support the connecting block 606, ensuring the directness and stability of force transmission, and improving the response speed and clamping force of the clamping mechanism 6. To ensure the overall stability of the tooling and the accuracy of its embedding and positioning, a leveling device is provided at the bottom of the base 1. The leveling device can compensate for the effects of uneven ground, ensuring that the tooling works in a horizontal state, thereby improving the verticality and positioning accuracy of the rotor embedding. The leveling device typically includes height-adjustable feet or pads, and the lifting rod 2 is a pneumatic or electric lifting rod. Pneumatic or electric drive can provide precise lifting control, achieve fast and smooth vertical movement, and facilitate integration with automated control systems, further improving the automation level and work efficiency of the entire tooling.

[0041] Working principle: When using this tooling, first place the workpiece to be embedded in the rotor 7 inside the mounting bracket 4 installed on the top of the base 1 and fix it. Then, the rotor 7 is clamped and fixed by the clamping mechanism 6. Specifically, the cylinder 602 installed inside the mounting plate 601 is activated. The output end of the cylinder 602 drives the fixedly connected connecting rod 603 to slide forward. While the connecting rod 603 slides, the externally rotatable rotating rod 604 rotates. The connecting column 605 fixedly connected to the rotating rod 604 has a connecting block 606 fixedly connected to its side wall and a clamping block 607. The clamping block 607 is affected by the rotation of the rotating rod 604 and clamps and fixes the rotor 7 inside.

[0042] After the rotor 7 is clamped and fixed, the lifting rod 2 connected to the top of the base 1 drives the top box 3 connected to the top of the lifting rod 2, as well as the rotating mechanism 5, clamping mechanism 6 and the clamped rotor 7 installed at the bottom of the top box 3 to descend together, embedding the rotor 7 into the workpiece.

[0043] When it is necessary to change the embedding position of rotor 7, that is, when rotor 7 needs to rotate to a designated position above the workpiece, motor 501 fixedly connected inside top box 3 is activated. The output end of motor 501 simultaneously drives first gear 502 and transmission rod 503. The rotation of first gear 502 drives the second gear 504 meshing with it to rotate. The bottom of transmission rod 503 is fixedly connected to the second gear 504 and drives rotating block 505 to rotate. The tail of rotating block 505 is connected to the second gear 504 and slidably connected in the groove 507 opened inside rotating disk 506. The rotation of rotating block 505 drives rotating disk 506 to rotate. Since the mounting plate 601 of clamping mechanism 6 is fixedly connected to the bottom of rotating disk 506, the rotation of rotating disk 506 will drive clamping mechanism 6 to make rotor 7 rotate to a designated position above the workpiece. Through the coordinated action of rotating mechanism 5 and clamping mechanism 6, the precise embedding and rotation positioning of rotor 7 is achieved.

[0044] After the rotor 7 is embedded, the cylinder 602 is started again, which drives the connecting rod 603 to slide backward, causing the rotating rod 604 to rotate in the opposite direction. Through the connecting column 605 and the connecting block 606, the clamping block 607 releases the rotor 7, thus completing the release of the rotor 7.
