[0001] This utility model relates to the field of vibration damping and fixing in milling slender shafts, and in particular to a vibration damping and fixing device for milling slender shafts based on hydraulic compensation. Background Technology
[0002] The anti-vibration fixing device for milling slender shafts is a device designed to solve the problem of vibration caused by poor rigidity during the milling process of slender shafts.
[0003] When milling slender shafts, the shaft is clamped and fixed by rotating a clamping plate on one side of the mounting block before milling. When the slender shaft vibrates, the vibration is transmitted to the clamping plate, causing it to wobble. This wobble leads to unstable clamping, affecting the fixation of the slender shaft and consequently impacting the effectiveness of the fixing device. Utility Model Content
[0004] The technical problem to be solved by this utility model is that when the slender shaft vibrates, the vibration is transmitted to the clamping plate, causing the clamping plate to wobble. This wobble leads to unstable clamping of the clamping plate, which affects the fixing effect of the slender shaft and thus affects the use effect of the fixing device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a vibration-damping and fixing device for slender shaft milling based on hydraulic compensation, including a placement block, a clamping plate on one side of the placement block, and a hydraulic compensation device on one side of the placement block. The hydraulic compensation device uses a hydraulic rod to perform hydraulic compensation on the clamping plate.
[0006] Preferably, the hydraulic compensation device includes a mounting block, bolts, a fixing frame, two hydraulic rods, two compensation blocks, a controller, and two displacement sensors. The mounting block is disposed on one side of the mounting block, and the bolts are inserted into one side of the mounting block for threaded fixation to the fixing frame. The two hydraulic rods are disposed on both sides of the fixing frame, and the compensation blocks are disposed at the output ends of the hydraulic rods, with the size of the compensation blocks matching the size of the hydraulic rods. The controller is disposed on one side of the fixing frame, and the two displacement sensors are disposed on both sides of the fixing frame to monitor the displacement of the two clamping plates.
[0007] Preferably, a positioning component is provided on one side of the mounting block to position the fixing frame.
[0008] Preferably, the positioning component includes a positioning groove and a positioning block formed on one side of the fixing frame. The positioning block is disposed on one side of the mounting block and its size is adapted to the size of the positioning groove on one side of the fixing frame.
[0009] Preferably, the fixing frame is provided with several anti-slip blocks on both sides to increase the friction on both sides of the fixing frame.
[0010] Preferably, a guide plate is provided on one side of the mounting block at an angle to guide the movement trajectory of the fixing frame.
[0011] Preferably, the output end of the hydraulic rod is provided with a reinforcing plate, and one side of the reinforcing plate is connected to the compensation block to improve the connection strength between the hydraulic rod and the compensation block.
[0012] Preferably, a rubber ring is provided near the output end of the hydraulic rod to improve the sealing performance at the output end of the hydraulic rod.
[0013] In summary, the beneficial effects of this utility model are as follows: By using a hydraulic compensation device, when the clamping plate vibrates due to the slender shaft, the hydraulic rod drives the compensation block to move, thereby resetting the clamping plate and completing the displacement compensation of the clamping plate. This prevents the clamping plate from swaying and displacing, which could affect the clamping effect on the slender shaft, thus improving the performance of the fixing device.

[0018] The implementation of this utility model will be described in detail below with reference to specific embodiments.
[0019] In this embodiment: Figures 1 to 6 The illustrated slender shaft milling vibration damping and fixing device includes a placement block 1, a clamping plate 2 on one side of the placement block 1, and a hydraulic compensation device 3 on the same side. The hydraulic compensation device 3 uses a hydraulic rod 34 to hydraulically compensate the clamping plate 2. When milling a slender shaft 4, a motor inside the placement block 1 rotates the clamping plate 2 on one side of the placement block 1 to clamp and fix the slender shaft 4. During milling, when the clamping plate 2 vibrates and shifts due to the slender shaft 4, the hydraulic compensation device 3 hydraulically compensates for this displacement.
[0020] Figures 1 to 6 The hydraulic compensation device 3 shown includes a mounting block 31, bolts 32, a fixing frame 33, two hydraulic rods 34, two compensation blocks 35, a controller 36, and two displacement sensors 37. The mounting block 31 is positioned on one side of the mounting block 1. The bolts 32 are inserted into one side of the mounting block 31 for threaded fixation to the fixing frame 33. The two hydraulic rods 34 are positioned on both sides of the fixing frame 33. The compensation blocks 35 are positioned at the output ends of the hydraulic rods 34, and their dimensions are compatible with the dimensions of the hydraulic rods 34. The controller 36 is positioned on one side of the fixing frame 33, and the two displacement sensors 37 are positioned on both sides of the fixing frame 33 to monitor the displacement of the two clamping plates 2. The displacement sensor 37 is model LK-G5001.
[0021] Figures 1 to 6As shown, when using the hydraulic compensation device 3, the fixed frame 33 can be moved to contact the mounting block 31 fixed on one side of the placement block 1. Then, the bolt 32 is rotated to thread the bolt through the mounting block 31 and the fixed frame 33. The hydraulic rods 34 fixed at both ends of the fixed frame 33 are positioned on one side of the clamping plate 2. When the clamping plate 2 is in use, the controller 36 fixed on one side of the fixed frame 33 controls the displacement sensor 37 to collect data on the vibration displacement of the clamping plate 2. The controller 36 then activates the hydraulic rods 34 fixed on one side of the fixed frame 33, causing the hydraulic rods 34 to move the compensation block 35 fixed at the output end. The compensation block 35 then moves the clamping plate 2 to compensate for the vibration displacement of the clamping plate 2. By using the hydraulic compensation device 3, when the clamping plate 2 is vibrating due to the slender shaft 4, the hydraulic rods 34 can move the compensation block 35 to reset the clamping plate 2, thus completing the displacement compensation of the clamping plate 2. This prevents the clamping plate 2 from swaying and affecting the clamping effect on the slender shaft 4, thereby improving the effectiveness of the fixing device.
[0022] Figures 1 to 6 The mounting block 31 shown has a positioning component 38 on one side to position the fixing frame 33. The positioning component 38 includes a positioning groove 381 and a positioning block 382 on one side of the fixing frame 33. The positioning block 382 is located on one side of the mounting block 31 and its size is adapted to the size of the positioning groove 381 on one side of the fixing frame 33. When the fixing frame 33 contacts the mounting block 31, the positioning block 382 fixed on one side of the mounting block 31 will engage with the positioning groove 381 on one side of the fixing frame 33 to position the fixing frame 33 on one side of the mounting block 31, thus facilitating the subsequent fixing of the fixing frame 33 with bolts 32.
[0023] Figures 1 to 6 The mounting bracket 33 shown has several anti-slip blocks 39 on both sides to increase the friction on both sides of the mounting bracket 33. By fixing the mounting bracket 33 to both sides with several anti-slip blocks 39, the friction on both sides of the mounting bracket 33 is increased, allowing the operator to grip the mounting bracket 33 more firmly for use.
[0024] Figures 1 to 6 The mounting block 31 shown has a guide plate 310 tilted on one side to guide the movement trajectory of the fixing frame 33. By fixing the guide plate 310 on one side of the mounting block 31, the movement trajectory of the fixing frame 33 is restricted when it comes into contact with the mounting block 31, making it easier for the fixing frame 33 to reach the interior of the mounting block 31.
[0025] Figures 1 to 6The output end of the hydraulic rod 34 shown is equipped with a reinforcing plate 311. One side of the reinforcing plate 311 is connected to the compensation block 35 to improve the connection strength between the hydraulic rod 34 and the compensation block 35. By fixing the reinforcing plate 311 to the compensation block 35 and the output end of the hydraulic rod 34, the connection strength between the two is improved, and the deformation at the connection point is prevented from affecting the use of the compensation block 35 and the hydraulic rod 34.
[0026] Figures 1 to 6 The hydraulic rod 34 shown is equipped with a rubber ring 312 near the output end to improve the sealing performance at the output end of the hydraulic rod 34. By fixing the rubber ring 312 to the side of the hydraulic rod 34 near the output end, the sealing performance of the side of the hydraulic rod 34 near the output end is improved, preventing debris milled from the slender shaft 4 from entering the interior of the hydraulic rod 34 and affecting its use.
[0027] Figures 1 to 6 As shown, during hydraulic compensation, the control module inside the controller 36 controls the displacement sensor 37 to collect signals, so that the vibration displacement data of the clamping plate 2 is collected. Then, the control module controls the hydraulic rod 34 to move the compensation block 35 fixed at the output end, so that the compensation block 35 moves the clamping plate 2 to complete the compensation of the vibration displacement of the clamping plate 2.
[0028] Working principle: When milling the slender shaft 4, the motor inside the placement block 1 rotates the clamping plate 2 on one side of the placement block 1 to clamp and fix the slender shaft 4. Then, the slender shaft 4 is milled. When the clamping plate 2 is displaced by the vibration of the slender shaft 4, the hydraulic compensation device 3 is used to hydraulically compensate for the displacement of the slender shaft 4. When using the hydraulic compensation device 3, the fixed frame 33 can be moved to contact the mounting block 31 fixed on one side of the placement block 1. Then, the bolt 32 is rotated to thread the bolt through the mounting block 31 and the fixed frame 33. The hydraulic rods 34 fixed at both ends of the fixed frame 33 are positioned on one side of the clamping plate 2. When the clamping plate 2 is in use, the controller 36 fixed on one side of the fixed frame 33 controls the displacement sensor 37 to collect data on the vibration displacement of the clamping plate 2. The controller 36 then activates the hydraulic rods 34 fixed on one side of the fixed frame 33, causing the hydraulic rods 34 to move the compensation block 35 fixed at the output end. This causes the compensation block 35 to move the clamping plate 2, thus compensating for the vibration displacement of the clamping plate 2. By using the hydraulic compensation device 3, when the clamping plate 2 is vibrating due to the slender shaft 4, the hydraulic rods 34 can move the compensation block 35 to reset the clamping plate 2, thus compensating for the displacement of the clamping plate 2. This prevents the clamping plate 2 from swaying and affecting the clamping effect on the slender shaft 4, thereby improving the effectiveness of the fixing device.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
