Description

Technical Field

[0001] This utility model relates to the field of rubber vibration damper technology, specifically to a pre-compression structure for a rubber vibration damper. Background Technology

[0002] Rubber shock absorbers are devices that utilize the elastic properties of rubber to reduce mechanical vibration, impact, and noise. They absorb and reflect vibration energy, preventing the propagation of vibration waves, thereby achieving the effects of shock absorption, noise reduction, and minimizing the damage caused by impact.

[0003] A search revealed a Chinese patent document disclosing a pre-compression structure for a rubber vibration damper [Announcement No.: CN212379005U]. This pre-compression structure for the rubber vibration damper includes a fixed base, a dual-axis cylinder connected to the top of the fixed base, a push plate connected to the power output end of the dual-axis cylinder, and through holes at the four corners of the push plate, with T-shaped guide sleeves installed in the through holes.

[0004] The pre-compression structure of the rubber vibration damper disclosed in this patent uses a T-shaped guide sleeve to allow the slide rod to slide within the T-shaped guide sleeve, which provides a guiding effect during the pre-compression process and improves the pre-compression effect. However, this pre-compression structure cannot accurately place the rubber vibration damper at the center of the top of the lower pressure plate when it is placed on the lower pressure plate. When the position of the rubber vibration damper is deviated, it can easily affect the force between the lower pressure plate and the upper pressure plate. Long-term unilateral force on the lower pressure plate and the upper pressure plate can easily affect the service life of the dual-axis cylinder and affect the subsequent pre-compression effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 As shown, a preloading structure for a rubber vibration damper includes a preloading machine body 1 and a base plate 2 slidably connected inside it. A clamping structure 4 is provided inside the base plate 2. The clamping structure 4 includes a fixed frame 42 and a sliding frame 41 fixedly connected to the top of the fixed frame 42. The fixed frame 42 is fixedly connected to a circular hole opened at the top of the base plate 2. Movable rods 43 are slidably connected to the circumference of the sliding frame 41. The bottom of the movable rods 43 contacts the interior of a rotating disk 9. The output shaft of a motor 3 is rotatably connected to the fixed frame 42. When the motor 3 is turned on to rotate the rotating disk 9, it can drive the movable rods. 43 slides radially and adjusts the position of the movable rod 43 so that the movable rod 43 can be inserted into the hole at the bottom of the rubber vibration damper, thereby restricting the position of the rubber vibration damper and avoiding the impact on the preloading operation due to the deviation of the rubber vibration damper's position. A motor 3 is provided at the bottom of the clamping structure 4, and a rotating disk 9 is fixedly connected to the output end of the motor 3. A fixed plate 5 is fixedly connected inside the preloading machine body 1. A limit structure 6 is provided inside the fixed plate 5. The limit structure 6 includes a groove 62 opened inside the fixed plate 5 and a baffle 61 sliding inside the groove 62. The baffle 61 is in the shape of a sliding groove 62. Figure 1In the indicated state, the limiting rod at the bottom of the base plate 2 cooperates with the limiting hole 63 at the top of the base plate 2 to restrict the position of the base plate 2. At the same time, the baffle 61 can block the front of the rubber vibration damper during the pre-compression operation, thereby increasing the safety of the pre-compression operation. The top of the base plate 2 is provided with several limiting holes 63, and the bottom of the baffle 61 is provided with several limiting rods that cooperate with the limiting holes 63. The right side of the bottom of the fixed plate 5 is provided with a positioning mechanism 64. When the baffle 61 moves downward, it can drive the limiting rods to insert into the limiting holes 63, thereby preventing the base plate 2 from moving arbitrarily and achieving position fixation.

[0018] The positioning mechanism 64 includes a spring sleeve 641 and a positioning pin 642 slidably connected inside it. The other end of the positioning pin 642 is fixedly connected to a moving block 643. The spring sleeve 641 is fixedly connected to the bottom right side of the fixed plate 5. A circular piece 645 is fixedly connected to the surface of the positioning pin 642. Grooves that cooperate with the moving block 643 are provided on the upper and lower sides of the right side of the baffle 61. A spring 644 is sleeved on the surface of the positioning pin 642. The two ends of the spring 644 are fixedly connected to the surface of the circular piece 645 and the inside of the spring sleeve 641, respectively. When the operator pulls the positioning pin 642 to move, the circular piece 645 moves accordingly and compresses the spring 644. When the circular piece 645 moves, the moving block 643 disengages from the groove on the right side of the baffle 61, thereby canceling the limitation on the baffle 61.

[0019] Both sides of the pre-compressor body 1 are fixedly connected to support seats. The support seats have slots 10 inside. Both sides of the base plate 2 are fixedly connected to card plates 11 that slide in the slots 10. By cooperating with the slots 10 inside the support seats, the straightness and stability of the base plate 2 when sliding can be ensured, and the base plate 2 can be prevented from shifting when moving.

[0020] A square groove 7 is provided on the surface of the baffle 61. The square groove 7 is located at the top of the front side of the baffle 61. The square groove 7 makes it easy to pull the baffle 61 to move up and down.

[0021] A U-shaped plate 8 is fixedly connected to the bottom of the fixed frame 42. The motor 3 is in contact with the bottom of the inner wall of the U-shaped plate 8. The U-shaped plate can support the motor 3, thereby increasing the stability of the motor 3.

[0022] A pressing device is installed at the top inside the pre-compressor body 1, and the bottom plate 2 is in the state of... Figure 1As shown, the pressing device is located directly above the base plate 2. The pressing device can pre-press the rubber shock absorber placed on the top of the base plate 2 by moving downward. It is worth noting that the technical features such as the pre-pressing machine body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can adopt conventional choices in this field. This technical solution will not elaborate further.

[0023] Working principle: When using the pre-compression machine body 1 to pre-compress the rubber shock absorber, first pull the positioning pin 642 to move it. The positioning pin 642 drives the circular piece 645 to move. At the same time, the moving block 643 disengages from the groove on the right side of the baffle 61. At this time, the operator can pull the baffle 61 upward through the square groove 7. The groove on the lower right side of the baffle 61 aligns with the moving block 643. The operator releases the positioning pin 642. At this time, the elastic force of the spring 644 can drive the positioning pin 642 and the moving block 643 back to the starting position. The moving block 643 inserts into the groove, which can fix and limit the baffle 61. The limitation on the bottom plate 2 is released. The operator can pull the bottom plate 2 outward and start the motor 3 to adjust the position of the movable rod 43 according to the size of the rubber shock absorber. The output shaft of the motor 3 drives the rotating disk 9 to rotate. At this time, the movable rod 43 can... As the rotating disk 9 rotates, it moves radially along the inner wall of the sliding frame 41, thereby adjusting the position of the movable rod 43. When the operator places the rubber shock absorber on top of the base plate 2, the hole at the bottom of the rubber shock absorber can be fitted onto the surface of the movable rod 43. This restricts the position of the rubber shock absorber, ensuring that its placement is correct and preventing it from shifting during pre-compression, which would affect the pre-compression effect. Then, the base plate 2 is pushed back into the pre-compression machine body 1. The above operation is then repeated to release the limit on the baffle 61 and pull the baffle 61 downward, so that the limiting rod at the bottom of the baffle 61 is inserted into the limiting hole 63. This restricts the position of the base plate 2 so that the rubber shock absorber can be placed below the pressing device. At this time, the pressing device at the top of the pre-compression machine body 1 can be started to pre-compress the rubber shock absorber.
