Description

Technical Field

[0001] This utility model belongs to the technical field of metal rotor holders, and in particular relates to a metal rotor holder that is easy to install. Background Technology

[0002] Metal rotor housings are metal structural components used to support and fix rotating rotors. They are usually made of high-strength metal materials and have high load-bearing capacity and stability. They are designed with rotor shaft mounting holes inside, which achieve a rigid connection between the rotor shaft and the rotor, ensuring the concentricity and balance of the rotor when rotating at high speed. As a key support structure of the rotor system, metal rotor housings can effectively transmit torque and reduce vibration, ensuring the operating accuracy of motor equipment.

[0003] Currently, metal rotor housings are generally fixed by tightening multiple bolts sequentially along the circumference during installation. Since the contact surface between the rotor housing and the rotor is a smooth plane, the concentricity of the two needs to be adjusted manually and each bolt needs to be pre-tightened one by one during the installation process. The operation is cumbersome and time-consuming, which not only increases the labor intensity of workers, but also requires repeated disassembly and reassembly of all bolts when maintaining the equipment or replacing parts, resulting in low overall installation efficiency and being unsuitable for use.

[0004] To address these issues, we offer an easy-to-install metal rotor mount. Utility Model Content

[0005] The purpose of this invention is to provide a metal rotor base that is easy to install. By combining the quick-fixing component and the positioning component, it solves the problems of cumbersome installation steps, long time consumption and low installation efficiency of the metal rotor base in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a metal rotor base for easy installation, comprising a motor. A quick-fixing assembly is provided on the top of the motor. Positioning components are fixedly connected to both sides of the top of the inner cavity of the quick-fixing assembly. The quick-fixing assembly includes a rotor base body. A sloped ring is fixedly connected to the top of the inner cavity of the rotor base body. A spring-loaded threaded plate is fixedly connected to the top of the motor. A positioning ring is fixedly connected to the top of the rotor base body. The positioning component includes two limiting shells. The top of each limiting shell extends to the outside of the rotor base body. A limiting plate is provided in the inner cavity of each limiting shell. A spring is fixedly connected to the top of each limiting plate. A pressure rod is fixedly connected to the bottom of each limiting plate. The bottom of the pressure rod extends to the inner cavity of the rotor base body. A limiting ring is fixedly connected to the top of the motor.

[0008] The present invention is further configured such that a mounting bracket is fixedly connected to the surface of the rotor base body, and mounting holes are provided on both sides of the rear side of the mounting bracket. The mounting bracket and mounting holes can install and fix the rotor base body, thereby improving the stability of the rotor base body.

[0009] The present invention is further configured such that the inner wall of the rotor seat body is provided with a thread for use with the spring plate threaded plate, and the slope ring is tapered. The thread facilitates the threaded connection between the inner wall of the rotor seat body and the surface of the spring plate threaded plate. The tapered slope ring can compress the spring plate threaded plate, causing it to deform and fasten the inner wall of the rotor seat body.

[0010] The present invention is further configured such that slide bars are fixedly connected to both sides of the inner cavity of the limiting shell, and slide grooves are provided on both sides of the limiting plate to cooperate with the slide bars. The slide bars and slide grooves facilitate the use of the limiting plate, improve its stability during the up and down movement, and prevent it from deviating.

[0011] The present invention is further configured such that the bottom of the limiting shell is provided with a through hole for use with the pressure rod, the top of the spring is fixedly connected to the inner wall of the limiting shell, the through hole allows the pressure rod to move smoothly up and down, and the spring can continuously compress the limiting plate.

[0012] The present invention is further configured such that inclined surfaces are provided on both sides of the top of the inner cavity of the limiting ring, and a ball is movably connected to the top of the pressure rod. The inclined surfaces at the top of the limiting ring facilitate the insertion of the pressure rod into the limiting ring, and the ball facilitates the sliding of the pressure rod inside the limiting ring.

[0013] The present invention is further provided that fixing holes are provided on both sides of the top of the rotor seat body for use with the limiting shell, and a rotor bearing is fixedly connected to the inner wall of the rotor seat body. The fixing holes facilitate the installation and fixing of the limiting shell, and the rotor bearing facilitates the rotation of the rotor.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes a quick-fixing component and a beveled ring and a threaded plate with inclined surfaces to automatically exert radial pressure on the threaded plate during the rotation and pressing of the rotor seat body. This causes the threaded plate to expand elastically outward and form multi-point locking with the inner wall of the rotor seat body, achieving uniform fastening with a single rotation. This avoids the tedious operation of tightening each circumferential bolt individually. At the same time, the cooperation between the positioning ring and the top structure of the motor automatically limits the axial displacement of the rotor seat body, ensuring the consistency of the installation position, significantly shortening the installation time, reducing the labor intensity of repeated manual calibration, and is especially suitable for maintenance scenarios that require frequent disassembly and assembly, significantly improving assembly efficiency.

[0016] 2. This utility model uses a positioning component with a spring-preloaded pressure rod and a limiting ring inclined guide structure. After the rotor seat body is initially positioned, the bottom end of the pressure rod is automatically embedded into the inner cavity of the limiting ring by the spring thrust. The rolling contact between the ball and the inclined surface guides the pressure rod to accurately lock into the bottom locking position of the limiting ring, forming a limiting constraint. Radial and circumferential positioning can be completed simultaneously during the pressing of the rotor seat body without manual intervention. This effectively eliminates the concentricity error caused by manual adjustment deviation in traditional installation. The coaxiality of the rotor seat body and the rotor is automatically maintained throughout the installation process, ensuring dynamic balance performance under high-speed rotation.

[0027] Specifically: the threads on the surface of the spring-loaded threaded plate 23 can engage with the threads inside the rotor seat body 21 to install and fix the rotor seat body 21; the slope ring 22 can squeeze the spring-loaded threaded plate 23 when the rotor seat body 21 rotates and moves downward, causing it to tilt outward, thereby tightly installing the rotor seat body 21 on the top of the motor 1; the positioning ring 24 can control the installation position of the rotor seat body 21, so that it can be accurately fixed on the top of the motor 1; the limiting plate 32 is used to prevent the pressure rod 34 from dislodging from the inner cavity of the limiting shell 31; the spring 33 can squeeze the limiting plate 32 and the pressure rod 34; the pressure rod 34 can be inserted into the limiting ring 35, and the limiting ring 35 positions the rotor seat body 21 to prevent it from shifting during installation.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, a mounting bracket 4 is fixedly connected to the surface of the rotor base body 21. Mounting holes are provided on both sides of the rear side of the mounting bracket 4. The inner wall of the rotor base body 21 is provided with threads that cooperate with the spring thread plate 23. The slope ring 22 is conical in shape. Sliding strips 5 are fixedly connected to both sides of the inner cavity of the limiting shell 31. Sliding grooves 6 that cooperate with the sliding strips 5 are provided on both sides of the limiting plate 32. A through hole that cooperates with the pressure rod 34 is provided at the bottom of the limiting shell 31. The top of the spring 33 is fixedly connected to the inner wall of the limiting shell 31. Inclined surfaces are provided on both sides of the top of the inner cavity of the limiting ring 35. A ball is movably connected to the top of the pressure rod 34. Fixing holes that cooperate with the limiting shell 31 are provided on both sides of the top of the rotor base body 21. A rotor bearing is fixedly connected to the inner wall of the rotor base body 21.

[0030] Specifically: the mounting bracket 4 and mounting holes can install and fix the rotor seat body 21, improving the stability of the rotor seat body 21; the threads facilitate the threaded connection between the inner wall of the rotor seat body 21 and the surface of the spring thread plate 23; the tapered slope ring 22 can compress the spring thread plate 23, causing it to deform and tighten the inner wall of the rotor seat body 21; the slide bar 5 and slide groove 6 facilitate the use of the limiting plate 32, improving its stability during up and down movement and preventing it from deviating; the through hole facilitates the smooth up and down movement of the pressure rod 34; the spring 33 can continuously compress the limiting plate 32; the inclined surface at the top of the limiting ring 35 facilitates the insertion of the pressure rod 34 into the limiting ring 35; the ball bearing facilitates the sliding of the pressure rod 34 inside the limiting ring 35; the fixing hole facilitates the installation and fixing of the limiting shell 31; and the rotor bearing facilitates rotor rotation.

[0031] The working principle of this utility model is as follows: During installation, the rotor seat body 21 is aligned with the top of the motor 1. Initial positioning is achieved through the mating structure between the positioning ring 24 and the top of the motor 1. When the rotor seat body 21 is rotated, the inner wall thread of the rotor seat body 21 engages with the surface thread of the spring plate 23, causing the rotor seat body 21 to move downward. At this time, the tapered inclined surface of the slope ring 22 continuously squeezes the spring plate 23, causing it to deform and tilt. The spring plate 23 expands outward and forms a friction lock with the inner wall of the rotor seat body 21 until the rotor seat body 21 rotates to the end, and the spring plate 23 and the rotor seat body 21... With a tight internal fit, when the rotor base body 21 is installed and pressed down, the spring 33 inside the limiting shell 31 pushes the pressure rod 34 downward. The ball at the bottom of the pressure rod 34 contacts the inclined surface at the top of the limiting ring 35 and slides along the inclined surface, guiding the pressure rod 34 into the bottom of the inner cavity of the limiting ring 35 to complete circumferential locking. During this process, the cooperation between the slide bar 5 and the slide groove 6 keeps the pressure rod 34 in vertical movement to avoid deviation. Radial and circumferential positioning can be completed simultaneously during the pressing down of the rotor base body 21 without manual intervention, effectively eliminating the concentricity error caused by manual adjustment deviation in traditional installation, and facilitating the installation of the rotor base body 21.
