Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figure 1 , Figure 2 and Figure 5 As shown in the embodiment of this utility model, the eccentric force dynamic balancing device includes a support platform 1. A first turntable bracket 11 and a second turntable bracket 12 are provided on the upper surface of the support platform 1. An eccentric shaft motor 13 is fixedly connected to the outer wall of the first turntable bracket 11. A rotating shaft 14 is fixedly connected to the output end of the eccentric shaft motor 13.

During testing, the operator can start the eccentric shaft motor 13, which drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the turntable 15 to rotate. The rotation of the turntable 15 stabilizes the overall testing process. At the same time, the torque force of the rotating shaft 14 is transmitted to the workpiece, and the eccentric force of the workpiece is detected by rotation. Through the above structure, the eccentric shaft motor 13 realizes the function of rotating the turntable 15. The structural characteristics of the turntable 15 make the device stable during the detection of eccentric force, which provides convenience for the detection of eccentric force. The size of the turntable 15 can be adjusted according to the specifications of the workpiece to be tested, which improves the adaptability during testing and makes the device more stable during testing.
[0021] like Figures 3 to 5As shown, the outer wall of the second turntable bracket 12 has a mounting groove 16. A synchronous pulley 36 is fixedly connected to one end of the rotating shaft 14 near the second turntable bracket 12. A fixing frame 3 is provided on the outer wall of the mounting groove 16. Fixing holes 31 are provided inside both the second turntable bracket 12 and the fixing frame 3. A fixing shaft 32 is provided on the inner wall of the fixing hole 31. A mounting plate 33 is provided on the outer wall of the fixing frame 3. Connecting holes 34 are provided inside both the fixing frame 3 and the mounting plate 33. A connecting shaft 35 is provided on the inner wall of the connecting hole 34. The outer wall of the synchronous pulley 36 is rotatably connected to the inside of the connecting shaft 35. During operation, when it is necessary to install or replace the synchronous pulley 36, the operator can install the fixing frame 3 onto the second turntable accordingly. The outer side of the bracket 12 is fixed to the second turntable bracket 12 by means of a fixed shaft 32 passing through a fixed hole 31. At this time, the synchronous pulley 36 can be installed. After installation, the mounting plate 33 is fixed to the fixed bracket 3 by means of a connecting shaft 35 passing through a connecting hole 34, providing stable support for the rotation of the synchronous pulley 36. When the synchronous pulley 36 rotates, it transmits torque to the workpiece, causing the workpiece to rotate. Through the above structure, the function of quickly assembling and disassembling the synchronous pulley 36 is realized by means of the cooperation between the fixed bracket 3 and the mounting plate 33. Different specifications of synchronous pulley 36 can be replaced according to the specifications of the workpiece. Compared with the traditional fixed installation structure, this device is more convenient to use and has higher adaptability to different specifications of workpieces.
[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the support platform 1, the first turntable bracket 11, and the second turntable bracket 12 all have mounting holes 2 inside, and mounting shafts 21 are provided on the inner walls of the mounting holes 2. When it is necessary to install the first turntable bracket 11 and the second turntable bracket 12 during operation, the mounting holes 2 inside can be aligned with the support platform 1, and the mounting shafts 21 can be used to pass through the mounting holes 2 to fix the first turntable bracket 11 and the second turntable bracket 12 above the support platform 1, improving the stability during operation and allowing the first turntable bracket 11 and the second turntable bracket 12 to be quickly assembled and disassembled for easy carrying. Through the above structure, the function of quickly assembling and disassembling the first turntable bracket 11 and the second turntable bracket 12 is realized by the cooperation of the mounting holes 2 and the mounting shafts 21. Compared with the traditional fixed installation structure, this device is more flexible in installation and also improves the convenience of transportation.
[0023] like Figures 4 to 5As shown, a detection shaft 4 is fixedly connected to the end of the synchronous pulley 36 away from the second turntable bracket 12. A clamping ring 41 is threadedly connected to the outer wall of the detection shaft 4, and a fixing ring 42 is fixedly connected to the outer wall of the detection shaft 4. During operation, after the synchronous pulley 36 is installed, the detection shaft 4 is connected to the synchronous pulley 36. After the connection is completed, the workpiece is installed on the outer wall of the detection shaft 4. Then, the clamping ring 41 is turned. When the clamping ring 41 is rotated, it rotates due to the threaded connection with the outer wall of the detection shaft 4. The workpiece is clamped and fixed by the clamping ring 41 and the fixing ring 42, which improves the stability of the workpiece during detection. The second turntable bracket 12 plays a supporting and fixing role. Through the above structure, the function of clamping and fixing the workpiece is realized by using the clamping ring 41 and the fixing ring 42. By adjusting the position of the clamping ring 41, workpieces of different specifications can be fixed, so that the clamping ring 41 and the fixing ring 42 remain stable between the workpieces, which improves the stability of the workpiece during detection and the data acquisition efficiency.
[0024] like Figure 4 As shown, a rubber ring 5 is provided on the outer wall of the clamping ring 41. During operation, the rubber ring 5 is provided on the outer wall of the clamping ring 41, which increases the friction between the clamping ring 41 and the workpiece and improves the stability of the workpiece during rotation. Through the above structure, the rubber ring 5 is provided on the outer wall of the clamping ring 41, which increases the friction when the detection shaft 4 clamps and fixes the workpiece, and improves the stability during detection.
[0025] like Figure 1 , Figure 3 and Figure 5 As shown, the mounting plate 33 has an encoder positioning hole 601 inside. During operation, the encoder positioning hole 601 inside the mounting plate 33 provides a positioning mounting point for the encoder to be installed later, and the encoder specifications can be flexibly adjusted as needed. Through the above structure, the encoder positioning hole 601 plays a role in assisting the installation of the encoder, so that the encoder can be quickly positioned and installed after the device is assembled, and can be flexibly replaced according to different needs, which improves the flexibility of the device during use.
[0026] like Figure 1 , Figure 3 and Figure 5 As shown, both the fixing frame 3 and the mounting plate 33 are made of lightweight aluminum. During operation, using lightweight aluminum for both the fixing frame 3 and the mounting plate 33 reduces overall weight while maintaining structural strength, facilitating disassembly and transportation, and reducing assembly difficulty. Through this structure, using lightweight aluminum for both the fixing frame 3 and the mounting plate 33 improves their corrosion resistance, extends the service life of the device, reduces overall weight, lowers labor intensity during assembly, and improves installation efficiency.
[0027] During operation, the first turntable bracket 11 and the second turntable bracket 12 are fixedly installed above the support platform 1. When detecting the eccentric force of the workpiece, the operator can start the eccentric shaft motor 13. The eccentric shaft motor 13 drives the rotating shaft 14 to rotate, which in turn drives the turntable 15 to rotate. The rotation of the turntable 15 stabilizes the entire detection process. At the same time, the torque force of the rotating shaft 14 is transmitted to the workpiece, and the eccentric force of the workpiece is detected by rotation. When it is necessary to install or replace the synchronous pulley 36 during operation, the operator can install the fixing bracket 3 pairs. The mounting plate 33 should be installed on the outside of the second turntable bracket 12, and the fixing frame 3 should be fixed to the second turntable bracket 12 by passing the fixing shaft 32 through the fixing hole 31. At this time, the synchronous pulley 36 can be installed. After installation, the mounting plate 33 should be fixed to the fixing frame 3 by passing the connecting shaft 35 through the connecting hole 34, providing stable support for the rotation of the synchronous pulley 36. When the synchronous pulley 36 rotates, it transmits torque to the workpiece, causing the workpiece to rotate. When it is necessary to install the first turntable bracket 11 and the second turntable bracket 12 during operation, the mounting hole 2 opened inside can be aligned with the support table 1, and the mounting plate 3 can be fixed to the second turntable bracket 12 by passing the fixing shaft 32 through the fixing hole 31. The mounting shaft 21 passes through the mounting hole 2 to fix the first turntable bracket 11 and the second turntable bracket 12 above the support platform 1, improving the stability during operation. During operation, after the synchronous pulley 36 is installed, the detection shaft 4 is connected to the synchronous pulley 36. After connection, the workpiece is installed onto the outer wall of the detection shaft 4. Then, the clamping ring 41 is rotated. When the clamping ring 41 rotates, it rotates due to the threaded connection with the outer wall of the detection shaft 4. The clamping ring 41 and the fixing ring 42 clamp and fix the workpiece, improving the stability of the workpiece during detection. The second turntable bracket 1... 2. It plays a supporting and fixing role; during operation, a rubber ring 5 is set on the outer wall of the clamping ring 41, which increases the friction between the clamping ring 41 and the workpiece and improves the stability of the workpiece during rotation; during operation, an encoder positioning hole 601 is opened in the inside of the mounting plate 33 to provide a positioning mounting point for the encoder to be installed later, and the encoder specifications can be flexibly adjusted as needed; during operation, both the fixing frame 3 and the mounting plate 33 are made of lightweight aluminum, which reduces the overall weight while maintaining structural strength, making it convenient for disassembly and transportation and reducing the difficulty of assembly.
