Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to an adjustable clamping damper. Background Technology

[0002] In the fields of mechanical engineering and vibration control, dampers, as key components for absorbing vibration energy and reducing mechanical vibration, are widely used in bridges, buildings, vehicles and various mechanical equipment.

[0003] When existing dampers are connected to external mechanical devices, they are usually directly fixed to the drive shaft of the external mechanical device through a connecting plate. However, the traditional fixing method has obvious shortcomings: on the one hand, the connection between the connecting plate and the drive shaft mostly relies on a single bolt fastening or rigid connection, which is prone to loosening under long-term vibration loads, leading to the failure of the connection between the damper and the mechanical device and affecting the normal working performance of the damper; on the other hand, in the existing connection method, friction will be generated between the drive shaft and the connecting plate, which can easily cause local wear of the drive shaft and connecting parts, leading to connection failure.

[0004] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a reasonably designed, simple, safe, and reliable adjustable clamping damper.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides an adjustable clamping damper, including a first cylinder, a piston is arranged inside the first cylinder, the outer surface of the piston abuts against the inner wall of the first cylinder, a push rod is fixedly connected to one side of the piston, a second cylinder is slidably connected to the outer surface of the first cylinder, a displacement sensor is fixedly connected to the outer surface of the push rod, the push rod and the displacement sensor pass through the inner walls of the first cylinder and the second cylinder, a connecting plate is fixedly connected to one end of the push rod and one end of the first cylinder, an auxiliary device is arranged on the outer surface of the connecting plate, the auxiliary device includes two extension plates, the two extension plates are symmetrically arranged and fixedly connected to the same side of the connecting plate, the two extension plates have through holes and each hole has a threaded rod, the two threaded rods are fixedly connected at their close ends, the two threaded rods have the same thread size and opposite direction, two clamping plates are threadedly connected to the outer surface of the threaded rods, the two clamping plates are symmetrically arranged between the two extension plates, and a rubber block is fixedly connected to the close side of each of the two clamping plates.

[0007] By using two clamping plates with rubber blocks, and with the help of two threaded rods, rotating the two rods causes each clamping plate to move in opposite directions until the rubber blocks on one side of the clamping plates completely clamp the drive shaft of the mechanical device connected to the connector. This provides auxiliary fixation between the connector and the shaft, preventing loosening and facilitating the normal operation of the damper. Simultaneously, a displacement sensor monitors the damper's displacement in real time during operation.

[0008] Preferably, the holes in the extension plate are concentric and of the same size, and a bearing is provided in the hole. The outer ring of the bearing is fixedly connected to the extension plate, and the inner ring is fixedly connected to the threaded rod.

[0009] By incorporating bearings, the friction between the threaded rod and the extension plate can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0010] Preferably, each of the two threaded rods has an operating block fixedly connected to one of its far ends, and the outer surface of the operating block is provided with a protrusion.

[0011] By setting an operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0012] Preferably, the inner walls of the two clamping plates are slidably connected to the same round rod, and the two ends of the round rod are respectively fixedly connected to the two extension plates.

[0013] By setting a round rod, when the clamping plate moves under the action of the threaded rod, the clamping plate will slide synchronously on the outer surface of the round rod, which can limit and guide the clamping plate.

[0014] Preferably, the connecting plate has a through hole, and the two rubber blocks have grooves on their adjacent sides. The hollow area formed by the two grooves matches the position, size, and shape of the through hole in the connecting plate.

[0015] By setting grooves, the shape and size of which are adapted to the inner wall of the connector, the contact area between the shaft and the rubber block can be increased, making the shaft more securely fixed.

[0016] Preferably, a sealing device is provided at the connection between the first cylinder and the second cylinder. The sealing device includes a rubber ring, which covers the open end of the second cylinder, and the inner wall of the rubber ring abuts against the outer surface of the first cylinder.

[0017] By setting a rubber ring, an auxiliary seal can be provided between the first cylinder and the second cylinder, which helps to improve the sealing performance between the first cylinder and the second cylinder and further ensures that the damper can maintain normal operation.

[0018] Preferably, the rubber ring is uniformly and fixedly connected with a plurality of slot blocks, and a threaded pin is inserted into the slot of the slot block. The threaded pin is fixedly connected to the outer surface of the second cylinder, and a nut is threadedly connected to the outer surface of the threaded pin.

[0019] By setting a threaded pin, inserting the threaded pin into the inner wall of the slot block, and then putting a nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the slot block, the rubber ring and the second cylinder can be auxiliaryly fixed, which helps to prevent the rubber ring from easily detaching from the second cylinder. At the same time, it also makes the rubber ring detachable, which is convenient for replacing the damaged rubber ring individually.

[0020] Preferably, a rubber pad is fixedly connected to the side of the nut near the slot block, the rubber pad having a round hole, and the shape and size of the round hole matching the threaded pin.

[0021] By placing a rubber pad on one side of the nut, it can replace one side of the nut in contact with one side of the slot block, which helps prevent the nut from loosening.

[0022] The beneficial effects of this utility model are as follows: By setting two clamping plates with rubber blocks, the clamping plates move towards each other under the action of the threaded rod until the rubber blocks on the clamping plates are fully clamped to the transmission shaft of the mechanical device connected to the connecting plate, thus achieving auxiliary fixation of the connecting plate and the transmission shaft. This helps prevent loosening of the connection between the connecting plate and the transmission shaft, facilitating the normal operation of the damper. A displacement sensor is set to monitor the displacement of the damper in real time during operation. A bearing is installed in the hole of the extension plate, which can reduce the friction between the threaded rod and the extension plate when rotating the threaded rod, making it easier to rotate the threaded rod. The threaded rod is fixedly connected to the operating block, and rotating the operating block drives the threaded rod to rotate, while the operating block... The surface is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and provide anti-slip effect when rotating the operating block; by setting a round rod, when the clamping plate is moved under the action of the threaded rod, the clamping plate will slide synchronously on the outer surface of the round rod, which can limit and guide the clamping plate; by setting a sealing device, the sealing between the first cylinder and the second cylinder is improved, further ensuring that the damper can maintain normal operation; by inserting the threaded pin into the inner wall of the slot block, and then putting the nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the slot block, the rubber ring and the second cylinder can be auxiliaryly fixed, which helps to prevent the rubber ring from easily detaching from the second cylinder.

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0029] See Figures 1 to 4 As shown, this embodiment is an adjustable clamping damper, including a first cylinder 1. A piston 2 is disposed inside the first cylinder 1, and the outer surface of the piston 2 abuts against the inner wall of the first cylinder 1. A push rod 3 is fixedly connected to one side of the piston 2. A second cylinder 4 is slidably connected to the outer surface of the first cylinder 1. A displacement sensor 5 is fixedly connected to the outer surface of the push rod 3. The push rod 3 and the displacement sensor 5 pass through the inner walls of the first cylinder 1 and the second cylinder 4. A connecting plate 6 is fixedly connected to one end of the push rod 3 and one end of the first cylinder 1. The outer surface of the connecting plate 6... An auxiliary device 7 is provided, which includes two extension plates 71. The two extension plates 71 are symmetrically arranged and fixedly connected to the same side of the connecting plate 6. The two extension plates 71 have through holes, and each hole is provided with a threaded rod 72. The two threaded rods 72 are fixedly connected at their close ends. The threads of the two threaded rods 72 are the same size but opposite in direction. The outer surface of the threaded rods 72 is threadedly connected to two clamping plates 73. The two clamping plates 73 are symmetrically arranged between the two extension plates 71. A rubber block 74 is fixedly connected to the close side of each of the two clamping plates 73.

[0030] By using two clamping plates with rubber blocks, and with the help of two threaded rods, rotating these rods causes each clamping plate to move in opposite directions until the rubber blocks on one side of each clamping plate completely clamp the drive shaft of the mechanical device connected to the connector. This provides auxiliary fixation between the connector and the shaft, preventing loosening and facilitating the normal operation of the damper. Simultaneously, a displacement sensor monitors the damper's displacement in real time during operation.

[0031] The holes in the extension plate 71 are concentric and the same size. A bearing 75 is installed in the hole. The outer ring of the bearing 75 is fixedly connected to the extension plate 71, and the inner ring is fixedly connected to the threaded rod 72.

[0032] By incorporating bearings, the friction between the threaded rod and the extension plate can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0033] An operating block 76 is fixedly connected to one end of each of the two threaded rods 72 that are far apart. The outer surface of the operating block 76 is provided with protrusions.

[0034] By setting an operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0035] The inner walls of the two clamping plates 73 are slidably connected to the same round rod 77, and the two ends of the round rod 77 are fixedly connected to the two extension plates 71 respectively.

[0036] By setting a round rod, when the clamping plate moves under the action of the threaded rod, the clamping plate will slide synchronously on the outer surface of the round rod, which can limit and guide the clamping plate.

[0037] The connecting plate 6 has a through hole, and the two rubber blocks 74 have grooves 78 on their adjacent sides. The hollow area formed by the two grooves 78 matches the position, size and shape of the through hole in the connecting plate 6.

[0038] By setting grooves, the shape and size of which are adapted to the inner wall of the connector, the contact area between the shaft and the rubber block can be increased, making the shaft more securely fixed.

[0039] A sealing device is provided at the connection between the first cylinder 1 and the second cylinder 2. The sealing device 8 includes a rubber ring 81, which covers the open end of the second cylinder 4, and the inner wall of the rubber ring 81 abuts against the outer surface of the first cylinder 1.

[0040] By setting a rubber ring, an auxiliary seal can be provided between the first cylinder and the second cylinder, which helps to improve the sealing performance between the first cylinder and the second cylinder and further ensures that the damper can maintain normal operation.

[0041] A number of slot blocks 82 are evenly and fixedly connected to the rubber ring 81. Threaded pins 83 are inserted into the slots of the slot blocks 82. The threaded pins 83 are fixedly connected to the outer surface of the second cylinder 4. Nuts 84 are threadedly connected to the outer surface of the threaded pins 83.

[0042] By setting a threaded pin, inserting the threaded pin into the inner wall of the slot block, and then putting a nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the slot block, the rubber ring and the second cylinder can be auxiliaryly fixed, which helps to prevent the rubber ring from easily detaching from the second cylinder. At the same time, it also makes the rubber ring detachable, which is convenient for replacing the damaged rubber ring individually.

[0043] A rubber pad 85 is fixedly connected to the side of the nut 84 near the slot block 82. The rubber pad 85 has a round hole, and the shape and size of the round hole match the threaded pin 83.

[0044] By placing a rubber pad on one side of the nut, it can replace one side of the nut in contact with one side of the slot block, which helps prevent the nut from loosening.

[0045] In actual use, the rotating operating block 76 drives the two threaded rods 72 to rotate. Under the limit of the round rod 77, the two threaded rods 72 will drive a clamping plate 73 to move towards each other until the groove 78 of the rubber block 74 on one side of the two clamping plates 73 completely clamps the transmission shaft of the mechanical device connected to the connector 6. This can provide auxiliary fixation between the connector 6 and the rotating shaft, which helps to prevent the connection between the connector 6 and the transmission shaft from becoming loose, and facilitates the normal operation of the damper. The threaded pin 83 is inserted into the inner wall of the slot block 82, and then the nut 84 is sleeved on one end of the threaded pin 83. The nut 84 is rotated so that the rubber pad 85 on one side of the nut 84 abuts against one side of the slot block 82. This can provide auxiliary fixation between the rubber ring 81 and the second cylinder 4. The rubber ring 81 can provide auxiliary sealing between the first cylinder 1 and the second cylinder 4, which helps to improve the sealing performance between the first cylinder 1 and the second cylinder 4, and further ensures that the damper can maintain normal operation.
