Description

Technical Field

[0001] This utility model relates to the field of drive mechanism technology, and in particular to a rotor belt driven automatic adjustment mechanism. Background Technology

[0002] In the field of rotor machining and assembly, belt drive mechanisms are widely used. Currently, traditional belt drive mechanisms, when dealing with rotors of different diameters, typically require manual measurement and replacement of belts of appropriate length, or manual adjustment of the tensioning device. This method is not only inefficient but also prone to human error leading to unsuitable belt tension, which in turn affects transmission performance, causing problems such as slippage and excessive wear. In automated assembly line operations, frequent manual intervention and adjustments severely restrict the improvement of production efficiency and increase labor costs, making it difficult to meet the high-efficiency and stable production demands of modern industry. Therefore, there is an urgent need to develop a belt drive adjustment structure that can adaptively adjust tension according to the rotor diameter to achieve unmanned and intelligent assembly line operations, thereby improving production efficiency and product quality stability.

The present invention provides a rotor belt drive automatic adjustment mechanism that can automatically adjust the belt tension according to the different diameters of the rotor without changing the belt length. It has a high degree of automation, can effectively save labor costs and has a wide range of applications.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] An automatic adjustment mechanism driven by a rotor belt includes a fixed bracket, on which a driving device is mounted.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rotor belt-driven automatic adjustment mechanism is applicable to rotor processing or assembly, especially to the processing or assembly of new energy rotors. The device includes a fixed support 1, on which a drive device 2, a rotary drive device 3, a tool holder 7, and a tensioning device 4 are mounted. The rotary drive device 3 is connected to the tool holder 7 via a connecting assembly 5 and is used to drive the tool holder 7 to rotate. The drive device 2 is connected to the tool holder 7 and the tensioning device 4 via a belt 9. The tensioning device 4 is used to tension the belt 9 to accommodate rotors of different diameters.

[0028] In this embodiment, the tool holder 7 includes a tool holder plate 72, which is connected to the rotating shaft 53, and a plurality of fixed follower wheels 71 are provided on the tool holder plate 72.

[0029] In this embodiment, the fixed bracket 1 is provided with an adjusting follower wheel 8, the belt 9 passes through the adjusting follower wheel 8 and is connected to the tool holder 7, the fixed bracket 1 is provided with an adjusting wheel groove 11, the adjusting follower wheel 8 is provided with a follower wheel bushing 81, the follower wheel bushing 81 passes through the adjusting wheel groove 11 and is fixed by a T-nut 82.

[0030] In this embodiment, the tensioning device 4 includes a tensioning drive device, a sliding assembly, and a tension follower wheel 44. The tensioning drive device drives the tension follower wheel 44 to slide along the sliding assembly. The sliding assembly includes a guide rail 47 and a slider 46. The guide rail 47 is mounted on the fixed bracket 1 via a guide rail fixing seat 45. The slider 46 is connected to the output end of the tensioning drive device and slides along the guide rail 47 under the drive of the tensioning drive device. The tensioning drive device includes a tensioning cylinder 41 mounted on the fixed bracket 1. The output end of the tensioning cylinder 41 is connected to the slider 46 via a floating joint 42. The fixed bracket 1 is provided with a sliding groove 12, and the tension follower wheel 44 is provided with a tensioning wheel bushing 43. The tensioning wheel bushing 43 passes through the sliding groove 12 and is mounted on the slider 46. Of course, in other embodiments, the tensioning drive device can also use a motor, electric push rod, hydraulic cylinder, etc., instead of a tensioning cylinder. The tensioning cylinder 41 drives the slider 46 to slide along the guide rail 47, thereby moving the tension follower 44 to achieve belt tensioning and untensioning. During use, the pressure of the tension follower 44 on the belt 9 can be precisely controlled by adjusting the air pressure of the cylinder, thus achieving dynamic adjustment of the belt 9 tension to adapt to rotors of different diameters.

[0031] In this embodiment, the rotary drive device is a rotary cylinder 31, which is mounted on the fixed bracket 1 via a cylinder mounting base 32. Preferably, the rotary cylinder 31 is a rodless side flange type cylinder. Of course, in other embodiments, the rotary drive device may also be a motor, an electric push rod, a hydraulic cylinder, etc.

[0032] In this embodiment, the connecting assembly 5 includes a rotating arm 52. One end of the rotating arm 52 is connected to a fisheye connector 51, and the other end is connected to a rotating shaft 53. The other end of the rotating shaft 53 is connected to the tool holder plate 72, and the other end of the fisheye connector 51 is connected to the output end of the rotary cylinder 31. To facilitate the rotation of the rotating shaft 53, a bearing seat 54 is provided on the fixed bracket 1, and a bearing is provided between the bearing seat 54 and the rotating shaft 53. The rotating shaft 53 and the rotating arm 52 are connected by a radial locking nut 55, and the rotating shaft 53 and the tool holder plate 72 are also connected by a radial locking nut 55. The radial locking nut 55 enables precise axial positioning and effectively prevents the rotating arm 52 and the tool holder plate 72 from loosening or falling off during rotation. The rotary cylinder 31 drives the rotating arm 52 to rotate, thereby causing the tool holder plate to press down and lift up, so that rotors of different diameters can be inserted under the tool holder 7, and the belt 9 can tension the rotor.

[0033] In this embodiment, the drive device 2 includes a servo motor 23 mounted on the fixed bracket 1, and the output end of the servo motor 23 is connected to the drive wheel 21 via a servo motor shaft 22. In other embodiments, a pneumatic motor, electric cylinder, or other similar device can be used to replace the servo motor.

[0034] The beneficial effects of this embodiment are as follows: Through the cooperation of the tensioning cylinder 41 and the sliding component in the tensioning device 4, the belt tension can be precisely adjusted according to the rotor diameter, eliminating the need for manual belt replacement or adjustment. This achieves dynamic adaptive tensioning, effectively avoiding slippage caused by insufficient tension in traditional transmissions, and improving the stability and reliability of the transmission system. The rotary drive device 3 uses a rotary cylinder 31 to drive the rotary arm 52 and the tool holder plate 72, automatically completing the pressing and lifting of the tool holder 7. This facilitates the rapid insertion and positioning of rotors of different diameters, significantly improving the automation level of the assembly line operation and reducing the need for manual intervention. The adjusting follower 8 is fixed by the adjusting wheel groove 11 and the T-nut, allowing for flexible adjustment of the belt's transmission path and wrap angle, further optimizing transmission efficiency. The radial locking nut 55 ensures precise axial positioning between the rotary shaft 53, the tool holder plate 72, and the rotary arm 52, effectively preventing components from loosening or falling off during high-speed rotation and enhancing the safety of the mechanism's operation. Furthermore, the tensioning cylinder 41 can precisely control the tension force by adjusting the air pressure, and the servo motor 23 provides stable drive. This automatic adjustment mechanism is adapted to the high automation requirements of new energy rotor processing and assembly, which can not only significantly save labor costs, but also adapt to efficient production under different working conditions, and has broad industrial application prospects. The rotor belt driven automatic adjustment mechanism shown in this embodiment can automatically adjust the belt length according to the change of rotor diameter. Through the coordinated work of the rotary cylinder and the tensioning cylinder, the automatic adaptation to different rotor diameters and belt tensioning functions are realized. This mechanism is suitable for automated assembly line operations without manual intervention, has a wide range of applications, is simple to operate, has a high degree of automation, and can effectively save labor costs.

[0035] Example 2

[0036] The difference between this embodiment and embodiment one is that in this embodiment, the fixed bracket 1 is provided with a chamfer follower wheel 6, the chamfer follower wheel is located below the connecting component 5, and the chamfer follower wheel 6 and the tool holder 7 are connected by a belt 9 to chamfer the rotor.

[0037] In this embodiment, a movable seat 61 is provided on the corner follower wheel 6, and a corner wheel groove 13 is provided on the fixed bracket 1. The movable seat 61 is inserted into the corner wheel groove 13 and is fixedly installed on the fixed bracket 1 by a corner T-nut.

[0038] The working principle or operation process in this implementation is as follows: After the rotor is placed in the designated position, the rotary cylinder 31 drives the rotary arm 52 to rotate through the fisheye joint 51, causing the rotary shaft 53 and the tool holder plate 72 to press down, so that the belt 9 passing through the fixed follower wheel 71 contacts the outer circumference of the rotor. Then, the tension cylinder 41 pushes the slider 46 to slide along the guide rail 47 through the floating joint 42, causing the tension follower wheel to move to tighten the belt. By adjusting the cylinder air pressure, the pressure of the tension wheel on the belt can be precisely controlled to achieve dynamic adjustment of the tension to adapt to rotors of different diameters. During this process, the wrap angle follower wheel 6 and the fixed follower wheel 71 on the tool holder plate 72 together form a wrap angle with the rotor, ensuring that the contact arc length of the belt around the rotor is reasonable. The servo motor 23 in the drive device drives the drive wheel 21 to rotate, and transmits the power to the tool holder and rotor through the belt to achieve rotation drive. When the rotor needs to be replaced, the rotary cylinder 31 retracts to lift the tool holder 7, the tension cylinder 41 resets, and the belt loosens, so that the rotor can be removed and enter the next round of operation. The entire process involves using a rotary cylinder to drive the tool holder for positioning, a tensioning cylinder to adjust the tension, and adjusting the follower wheel and wrap angle to optimize the transmission, thereby achieving fully automatic adaptation and efficient transmission for new energy rotors of different diameters.

[0039] The beneficial effects of this embodiment are as follows: the wrap angle follower and the fixed follower on the tool holder plate together form the wrap angle of the rotor through the belt, ensuring that the contact arc length (wrap angle) of the belt around the rotor is maintained within a reasonable range, avoiding slippage caused by too small a wrap angle, and effectively improving the torque transmission capability and stability of the transmission system.

[0040] The advantages of this invention are as follows: Through the cooperation of the tensioning cylinder and the guide rail slider assembly in the tensioning device, the belt tension can be precisely adjusted according to the rotor diameter, eliminating the need for manual belt replacement or adjustment. This achieves dynamic adaptive tensioning, effectively avoiding slippage caused by insufficient tension in traditional transmissions and improving the stability and reliability of the transmission system. The rotary drive device uses a rotary cylinder to drive the rotary arm and tool holder plate, automatically completing the downward and upward movement of the tool holder. This facilitates the rapid insertion and positioning of rotors of different diameters, significantly improving the automation level of assembly line operations and reducing the need for manual intervention. The adjusting pulley, fixed by the adjusting pulley groove and T-nut, allows for flexible adjustment of the belt's transmission path and wrap angle, further optimizing transmission efficiency. The radial locking nut ensures precise axial positioning between the rotating shaft, the tool holder plate, and the rotary arm, effectively preventing components from loosening or falling off during high-speed rotation and enhancing the safety of the mechanism's operation. Furthermore, the tensioning cylinder can precisely control the belt tension by adjusting the air pressure. The wrap angle pulley and the fixed pulley on the tool holder plate together form the wrap angle with the rotor via the belt, ensuring that the contact arc length (wrap angle) of the belt around the rotor is maintained within a reasonable range, avoiding slippage caused by an excessively small wrap angle, and effectively improving the torque transmission capacity and stability of the transmission system. This utility model provides a rotor belt-driven automatic adjustment mechanism that can automatically adjust the belt tension according to different rotor diameters without changing the belt length. It has a high degree of automation, effectively saves labor costs, and has a wide range of applications.
