Description

Technical Field

[0001] This invention relates to the field of hydraulic pump auxiliary equipment technology, specifically a damping device for an axial piston pump. Background Technology

[0002] Axial piston pumps are mainly used to transmit and regulate hydraulic energy. They consist of main components such as cylinder, piston, spring, and axial valve. Through the reciprocating motion of the piston in the cylinder, oil is drawn in and discharged, thereby transmitting energy.

[0003] During operation, axial piston pumps generate vibrations and noise, which not only affect the normal operation of the pump but also have a certain impact on the surrounding environment and personnel. If vibration dampers and vibration isolators are directly installed on the axial piston pump, these devices have certain requirements for temperature and humidity, and the operation of such structures is relatively complicated. In addition, the design and manufacture of vibration isolators are also complex and costly, which is not conducive to practical use.

[0036] Adjustment component 5 is mounted on base 1 and connected to first fastening component 2. Adjustment component 5 is used to improve the stability of first fastening component 2.

The cylindrical pull block 51 is located on the side of base 1. The connecting cable 52 is movably disposed inside base 1. The steering ring 53 is fixedly mounted on base 1. The steering pulley 54 is rotatably disposed inside base 1.

The slider 55 is slidably disposed on the cylindrical pull block 51. The clamping blocks 56 are located on the side of the slider 55. Shaft 57 is mounted on cylindrical pull block 51.

The force generated by first reset torsion spring 212 is greater than the force generated by second reset torsion spring 512, further ensuring the rationality of the overall device and ensuring the performance of the overall device.

[0037] Working principle: Four fastening bolts 21 are threaded at four diagonal points on the base 1. The fastening bolts 21 are rotatably connected to the cover plate 22. The four fastening bolts 21 can be driven by a first belt 214 that moves inside the cover plate 22. An L-shaped rack 23 is fixed to the cover plate 22. A first gear 24 is fixed to a first lead screw 32 and meshes with a second gear 25. While sliding inside the base 1, the convex block 26 is also connected to the base 1 using a first return spring 27. The convex block 26 has openings that cooperate with the L-shaped rack 23. The limiting tooth 261, the L-shaped rack 23 meshing with the second gear 25, the movable seat 28 sliding inside the base 1, the movable seat 28 also threadedly connected to the threaded rod 29 rotating inside the base 1, the slide rod 211 sliding on the base 1 and the movable seat 28, and the slide rod 211 also connected to the movable seat 28 using the second return spring 210, so when the fastening bolt 21 is rotated to install the base 1 in the predetermined installation position, since the cover plate 22 can slide on the base 1, the fastening bolt 21 rotates, such as Figure 2As shown, the cover plate 22 will slide downwards, pressing the slide rod 211 while the L-shaped rack 23 slides downwards simultaneously, thereby driving the second gear 25 to rotate. The first gear 24 rotates along with the second gear 25, and the first lead screw 32 rotates synchronously. At this time, the position of the first slide block 31 and the second slide block 41 can be changed as the base 1 is connected to the mounting surface, so that while the base 1 is fixed on the mounting surface, the second fastening component 3 fixes the position of the axial piston pump, and the damping component 4 contacts the axial piston pump to eliminate the influence of vibration during operation. After fixing, the slide rod 211 pushes the convex block 26 to slide towards the L-shaped rack 23, and the L-shaped rack 23 slides downwards and will contact the convex block. The limiting teeth 261 on 26 engage to restrict the position of the L-shaped rack 23, thereby restricting the rotation of the first lead screw 32 and improving overall stability. In the process, the size of the second gear 25 is larger than that of the first gear 24, so the rotation frequency of the first gear 24 is greater than that of the second gear 25, providing the first lead screw 32 with sufficient rotations to ensure the connection between the first slide block 31 and the axial piston pump. At the same time, in the initial state, there is a certain distance between the slide rod 211 and the convex block 26, so that the L-shaped rack 23 first descends to a position where it can engage with the convex block 26, and then the convex block 26 slides towards the L-shaped rack 23 to engage with it, ensuring that the established structure can operate stably and reasonably.

[0038] Both first slide blocks 31 slide on the base 1, and their mirror-image, oppositely spiraled threads are threadedly connected to the first slide blocks 31. The driving worm gear 44 is fixed to the first lead screw 32, which is rotatable inside the base 1. The movable cylinder 33 rotates inside the base 1 and is also threadedly connected to the first lead screw 32. The auxiliary pulley 34 and the threaded cylinder 36 are both rotatably disposed inside the first slide blocks 31. Through the rotation of the auxiliary pulley 34, the movable cylinder 33 and the threaded cylinder 36 can be connected by a second belt 35. The fastening screw 37 is threadedly disposed inside the threaded cylinder 36. Therefore, the first... When the lead screw 32 rotates, the movable cylinder 33 and the driving worm gear 44 rotate synchronously, and the first slide 31 slides toward the axial piston pump. When the first slide 31 contacts the axial piston pump, under the action of the synchronous rotation of the threaded cylinder 36, the fastening screw 37 will unscrew the threaded connection between the first slide 31 and the axial piston pump. Then, with the cooperation of multiple fastening screws 37, the position of the axial piston pump is fixed on the base 1. At this point, the damping component 4 can be adjusted together with the second fastening component 3. Moreover, the pitch of the second lead screw 42 is smaller than the pitch of the first lead screw 32, so the first slide 31 can contact the axial piston pump before the second slide 41.

[0039] The second slide block 41 slides on the base 1, and the second lead screw 42 rotates inside the base 1. Two sections of threads with opposite helical directions are mirror-imagely arranged on the second lead screw 42, which are threadedly connected to the two second slide blocks 41 respectively. The driven worm gear 43 fixed on the second lead screw 42 is threadedly connected to the driving worm gear 44 rotating inside the base 1. The connecting rod 45 slides on the second slide block 41, and the connecting seat 46 slides synchronously on the second slide block 41. The connecting seat 46 is also connected to the second slide block 41 by an energy-absorbing spring 47. The connecting rod 45 and the connecting seat 46 are connected by a movable connecting rod 48, which connects to the axial piston pump. The arc-shaped block 49 is fixed on the connecting rod 45. The axial piston pump is placed on the base 1. The first fastening assembly 2 is operated, and the first gear 24 contained therein rotates with the second gear 25. Then the first lead screw 32 rotates synchronously. Since the driving worm 44 is fixed on the first lead screw 32, the driving worm 44 rotates together. After the driving worm 44 rotates, the two second slides 41 slide toward the axial piston pump, so that the arc-shaped block 49 contacts it. When the axial piston pump is running, the energy-absorbing spring 47 uses its own elastic potential energy to counteract the vibration generated by the operation of the body, thereby achieving the effect of energy absorption and shock absorption.

[0040] The connecting cable 52 is movable inside the base 1. The base 1 has an opening slot for the connecting cable 52 to move. The steering ring 53 is fixed to the side of the slot, and the steering pulley 54 slides inside the base 1. The end of the connecting cable 52 passes through the steering ring 53, then around the steering pulley 54 and is fixedly connected to the movable seat 28. The fixing block 213 fixed on the threaded rod 29 is also connected to the base 1 using the first return torsion spring 212. The other end of the connecting cable 52 is connected to the cylindrical pull block 51 inside. The rotating winding roller 511 is fixedly connected, and the winding roller 511 is synchronously connected to the cylindrical pull block 51 via the second return torsion spring 512. The slider 55 slides on the cylindrical pull block 51, and the slider 55 is also movably connected to the clamping block 56 via the connecting short rod 59. The two clamping blocks 56 are movably connected via the connecting shaft 57 set on the cylindrical pull block 51. The two clamping blocks 56 are also connected by the clamping torsion spring 58. The two clamping blocks 56 synchronously use the elastic force of the clamping torsion spring 58 to clamp and restrict the connecting cable 52. Figure 11 and Figure 12In this state, pulling the cylindrical pull block 51 causes the threaded rod 29 to rotate under the connection of the connecting cable 52. The movable seat 28 then slides away from the L-shaped rack 23, and the slide rod 211 slides along with the movable seat 28, not contacting the convex block 26. Under the action of the first return spring 27, the convex block 26 returns to its initial position and does not engage with the L-shaped rack 23. At this time, rotating the fastening bolt 21 in the opposite direction causes the first lead screw 32 and the second lead screw 42 to rotate synchronously, thus removing the overall structure's restriction on the axial piston pump. After releasing the cylindrical pull block 51, under the action of the first return torsion spring 212, the threaded rod 29 rotates in the opposite direction, and the movable seat 28, along with the slide rod 211, returns to its initial position. The threaded rod 29 also rewraps the part of the connecting cable 52 that has detached onto the threaded rod 29 for future use. Pushing the slider 55, under the action of the auxiliary rod 510 connected to the short rod 59, will expand... The distance between the two clamping blocks 56 ensures that they do not contact the connecting cable 52, and the force generated by the second reset torsion spring 512 is less than that of the first reset torsion spring 212. At this time, pulling the cylindrical pull block 51 again can pull out the part of the connecting cable 52 that is wrapped around the winding roller 511. Since the excess of the connecting cable 52 left outside increases, the position of the cylindrical pull block 51 can be changed through the preset groove on the base 1. Then, the slider 55 is released, and the clamping block 56 can clamp and restrict the connecting cable 52 to meet different actual usage scenarios. When the clamping block 56 is adjusted again to not contact the connecting cable 52, the first reset torsion spring 212 is in the state after potential energy release, while the second reset torsion spring 512 is in the state of potential energy compression. The second reset torsion spring 512 will drive the winding roller 511 to rotate, and wrap the excess part of the connecting cable 52 around the surface of the winding roller 511 to meet the actual usage requirements.
