Description

Technical Field

[0001] This utility model relates to the field of drive mechanism technology, and in particular to an adjustment device that can automatically adjust the center height of a rotor. Background Technology

[0002] Against the backdrop of the booming development of the new energy vehicle industry, the electric drive rotor, as a core power component, is experiencing continuous market expansion and has extremely broad development prospects. During the mass production of electric drive rotors, initial imbalances are inevitably generated due to factors such as material properties and manufacturing processes. If the rotor has excessive imbalance, it will cause severe vibrations and abnormal noise to related automotive components under high-speed rotation conditions, significantly shortening component lifespan and potentially posing serious safety hazards. Therefore, dynamic balancing of the electric drive rotor has become a crucial step in ensuring product performance and reliability.

[0003] Currently, traditional rotor drive devices exhibit numerous technical bottlenecks in practical applications. On one hand, the rotor center height adjustment of existing devices largely relies on manual or semi-automatic operation. This adjustment method is not only inefficient but also lacks precision, failing to meet the production demands for rapid switching between rotors of different diameters. On the other hand, for rotors of different diameters, existing devices require replacement of the drive belt or manual adjustment of the tensioning device. Specifically, either a belt of appropriate length needs to be precisely measured and replaced manually, or the tensioning device needs to be manually adjusted to adapt to the transmission requirements of rotors of different diameters. This operation method is not only time-consuming and labor-intensive but also prone to belt tension inaccuracies due to human error, leading to slippage and excessive belt wear during transmission. In highly automated assembly line operations, frequent manual intervention and adjustments severely hinder the improvement of production efficiency, significantly increase labor costs, and fall far short of the efficient, stable, and intelligent production requirements of modern industry.

[0004] In summary, to meet the urgent needs of the new energy vehicle industry for efficient and high-quality production of electric drive rotors, it is imperative to develop an adjustment device that can automatically adjust the center height according to the rotor diameter and achieve adaptive belt tensioning. This would drive the electric drive rotor dynamic balancing process towards unmanned and intelligent operation, effectively improving production efficiency and product quality stability.

[0040] Example 2

[0041] The difference between this embodiment and embodiment one is that in this embodiment, a limiting component 7 is provided at the top of the adjusting bracket 3. The limiting component 7 is connected to the tensioning device 8 and the clamping device 6 through a belt 10. The limiting component 7 and the clamping device 6 wrap around the rotor through the belt 10.

[0042] In this embodiment, the limiting component 7 includes two limiting follower wheels 71. The limiting follower wheels 71 are mounted on the adjusting bracket 3 via limiting follower wheel mounting plates 72. Both limiting follower wheels 71 are connected to the tensioning device 8 and the clamping follower wheel 63 via belts 10. In this embodiment, the clamping follower wheel 63 at the top of the clamping claw 61 is connected to the limiting follower wheel 71 on the same side via belts, such as... Figure 3 As shown, the transmission route of the belt 10 is connected by two clamping follower pulleys 63 and two limiting follower pulleys 71, which guide the belt 10 to wrap around the rotor. By setting the limiting follower pulleys 71, it can be ensured that the wrap angle between the rotor and the belt 10 is within a reasonable position, thus avoiding slippage during the transmission process.

[0043] In this embodiment, after the belt 10 is output from the drive motor wheel 92, it first passes through the second fixed follower wheel 200, then sequentially passes through the middle and end of one of the clamping jaws 61, and is connected to the rotor; next, the belt 10 passes through the limiting follower wheel 71 on the same side as the clamping jaw 61, is adjusted by the moving follower wheel 83, and then connects to another limiting follower wheel 71 and is connected to the rotor; thereafter, the belt 10 passes through the end of the clamping jaw of another clamping jaw, connects to the clamping follower wheel 63 in the middle of the clamping jaw, and is then connected to the first fixed follower wheel 100, and finally returns to the drive motor wheel 92, forming a closed-loop transmission structure.

[0044] The working principle or operation process in this implementation is as follows: First, the device is powered on and initialized. The center height adjustment motor 21 drives the lead screw 43 to rotate, which, through the synchronous belt 5, causes the adjustment bracket 3 to slide down the guide rail 42 to the preset initial position. At this time, the clamping cylinder 301 is in the retracted state, which drives the clamping jaws 61 to rotate around the jaw stand 62 and open, forming an opening space for the rotor to be placed. After the rotor is placed between the two clamping jaws 61, the clamping cylinder 301 extends and pushes the clamping jaws 61 to rotate and clamp the rotor. The clamping follower wheel 63 drives the belt to adhere to the rotor surface. Next, the center height adjustment motor 21 starts according to the rotor diameter parameters. The drive wheel 24 drives the lead screw pulley 45 to rotate through the synchronous belt 5. The rotation of the lead screw 43 drives the nut seat 44 to move along the lead screw axis, which drives the adjustment bracket 3 to slide up and down along the guide rail 42. The four sets of sliders 41 slide synchronously to ensure smooth movement until the rotor center height reaches the preset position. Subsequently, the belt tensioning cylinder 811 extends, pushing the movable follower seat 823 to slide along the tensioning guide rail 821 via the cylinder telescopic plate 824. The movable follower 83 tightens the belt 10, dynamically adjusting the belt tension. Simultaneously, the two limiting follower wheels 71 of the limiting assembly 7 cooperate with the clamping follower wheel 63 on the top of the clamping claw 61, guiding the belt 10 to form a reasonable wrap angle and preventing transmission slippage. Finally, the drive servo motor 91 starts, and the drive motor wheel 92 rotates, driving the belt 10 to rotate. The torque is transmitted to the rotor surface through the clamping follower wheel 63, accelerating the rotor to the preset speed, completing the fully automated process from clamping and center height adjustment to drive rotation.

[0045] The beneficial effect of this embodiment is that by forming a four-point guiding structure with the limiting follower 71 and the clamping follower 63, the wrap angle of the belt 10 to the rotor can be controlled within a reasonable range, effectively reducing slippage during transmission.

[0046] The advantages of this invention are as follows: The center height drive device drives the lead screw to move the adjusting bracket, achieving automatic adjustment of the rotor's center height. This meets the installation and transmission requirements of rotors of different specifications, significantly improving the device's versatility. Clamping drive devices on both sides drive the clamping jaws to complete the clamping and opening action, facilitating quick clamping of rotors of different diameters. The tensioning device automatically adjusts the belt length and tension according to the rotor diameter, effectively preventing slippage during transmission, improving torque transmission efficiency, and precisely adapting to the processing requirements of rotors of different specifications. The drive motor wheel, along with the fixed follower wheel, clamping follower wheel, and moving follower wheel, allows the belt to form a wrap angle on each transmission wheel and the rotor, facilitating the transmission of torque from the servo motor to the rotor, thus driving rotor rotation. The center height adjustment assembly uses a symmetrical layout of two sets of guide rails and four sets of sliders, enabling stable movement of the adjusting bracket with minimal error. The four-point guiding structure formed by the limiting component and the clamping follower wheel controls the belt wrap angle on the rotor within a reasonable range, effectively reducing slippage during transmission. This utility model provides an automatic adjustment device for the center height of a rotor, which can automatically adjust the center height of the rotor and automatically adjust the belt length and tension according to the rotor diameter. It has a high degree of automation, can effectively save labor costs and has a wide range of applications.
