Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts, in particular to a parallel independent air spring vibration isolation platform. Background Art

[0002] Air spring is a rubber bag reinforced by cords, filled with compressed air, and a vibration-damping rubber product that uses the compressibility of gas to act as a spring. There are long pillow type, gourd type and diaphragm type. The air springs used in automobiles can be roughly divided into free film type, hybrid type, sleeve type and bag type air springs. The rubber bag structure is similar to that of tubeless tires, consisting of an inner rubber layer (airtight layer), an outer rubber layer, a cord reinforcement layer and a wire ring. The load is mainly borne by the cord, and the material of the cord is the decisive factor in the pressure resistance and durability of the air spring.

[0003] In the prior art, air springs are usually used for automobile shock absorption and silencing, which can effectively improve the sound insulation and shock absorption effects of the car during driving. Since air springs must be tested to see if they meet the use requirements before they go out, the air springs are usually placed on the ground and pressed by multiple plates, and the feedback of the air springs is observed for detection. Air springs simply placed on the ground are prone to tipping and shaking when in contact with the plates, which will affect the judgment of the staff, thereby reducing the efficiency of air spring detection.

[0004] To this end, we designed a parallel independent air spring vibration isolation platform. Summary of the invention

[0005] The utility model aims to solve the problem that the existing detection tools affect the detection efficiency of air springs and proposes a parallel independent air spring vibration isolation platform.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A parallel independent air spring vibration isolation platform includes two fixed platforms, each of which is provided with a device body for detection, a compression shaft symmetrically arranged at the bottom of the fixed platform for dispersing excessive pressure, a rubber pad for increasing friction with the ground is arranged on the compression shaft, and threaded rods for improving the stability of the device body are symmetrically arranged on the fixed platform. The two fixed platforms are fixedly connected by a first connecting shaft, an iron frame for increasing the connection strength of the first connecting shaft is arranged on the fixed platform, a fixture for adjusting the balance of the device body on the fixed platform is arranged on the fixture, and a clamping ring for limiting the movement of the device body is arranged on the fixture.

[0008] Preferably, a column is fixedly mounted on the fixing platform, and a hole is opened on the column, one end of the threaded rod is provided with a drilling end for penetrating the ground, the threaded rod is adapted to the hole, and the drilling end penetrates the hole.

[0009] Preferably, the first connecting shaft is fixedly connected to the fixing platform via a fastener, and the fixing platform is provided with a plurality of second connecting shafts for improving stability.

[0010] Preferably, both ends of the iron frame are groove-shaped, and a welding pipe for reducing bending of the fixing platform is provided inside the iron frame.

[0011] Preferably, the fixer is fixedly connected to the fixing platform via a fastener, an elastic shaft for improving the pressing device body is provided inside the fixer, and auxiliary bodies are provided at both ends of the fixer.

[0012] Preferably, the clamping ring is fixedly connected to the auxiliary body via an auxiliary shaft, and the clamping ring abuts against the device body.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can effectively improve the stability of the device body on the fixing table after the device body is placed on the fixing table by arranging the fixer and the clamping ring, and can avoid displacement and tipping when multiple plates are pressed on the device body, further improving the quality of feedback after the device body is pressed, and at the same time making it easy for the staff to obtain effective feedback data, thereby improving the detection efficiency of the device body.

[0015] The utility model arranges the drilling end so that when the device body is pressed by a larger plate, distortion of the compression shaft and the rubber pad can be avoided, which causes the fixing platform to tilt. At the same time, when the drilling end is fixed on the ground, the stability of the fixing platform itself on the ground can be further improved. The clamping effect of the clamping ring on the device body can be improved through the elastic shaft, and the rebound effect of excess inertia generated after the device body is pressed by the plate can be reduced.

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A parallel independent air spring vibration isolation platform includes a fixed platform 1. The fixed platform 1 is provided with two frames in total and arranged in parallel. Two device bodies 2 can be detected at the same time. The fixed platform 1 is composed of aluminum alloy wear-resistant metal components and has anti-deformation effect, which can effectively improve the service life of the fixed platform 1. The device body 2 is an existing air spring, which is mainly used for shock absorption and sound insulation components in automobiles. The compression shaft 3 is an existing hydraulic damper, which can effectively absorb the excess pressure on the device body 2 and avoid damage to the device body 2 that has not been shipped out of the factory. The rubber pad 4 can increase the friction between the compression shaft 3 and the ground, further improving the stability of the fixed platform 1 on the ground.

[0022] Threaded rods 6 for improving the stability of the device body 2 are symmetrically arranged on the fixed platform 1. The threaded rods 6 are threaded screws in the prior art and are mainly used to adjust the depth of the drilling end 7 in the ground. A column 5 is fixedly installed on the fixed platform 1. The column 5 is a limiting component and is mainly used to limit the adjustment length of the threaded rod 6. A hole is opened on the column 5. The hole is used to place the threaded rod 6. One end of the threaded rod 6 is provided with a drilling end 7 for penetrating the ground. The drilling end 7 is overall from thick to thin, and the thin end is conducive to piercing the ground, which is convenient for adjusting the threaded rod 6. The threaded rod 6 is adapted to the hole, and the drilling end 7 penetrates the hole. The drilling end 7 is fixed to the threaded rod 6 by welding.

[0023] The two fixed platforms 1 are fixedly connected by a first connecting shaft 8. The first connecting shaft 8 is a connecting component of the two fixed platforms 1, and secondly, a main component used for the two fixed platforms 1 to be symmetrical with each other. The first connecting shaft 8 is fixedly connected to the fixed platform 1 by fasteners. A plurality of second connecting shafts 9 for improving stability are provided on the fixed platform 1. The second connecting shafts 9 improve the connection strength of the two fixed platforms 1 on the basis of the first connecting shafts 8, and are all fixed to the fixed platform 1 by fasteners.

[0024] An iron frame 10 for increasing the connection strength of the first connecting shaft 8 is provided on the fixed platform 1. The iron frame 10 is an auxiliary component. After the use of the two fixed platforms 1 is determined, the two fixed platforms 1 are welded through the iron frame 10 to make the two fixed platforms 1 become one. The two ends of the iron frame 10 are groove-shaped, and a welding pipe for reducing the bending of the fixed platform 1 is provided inside the iron frame 10. The welding pipe is a welding route formed after the welding process.

[0025] The fixing platform 1 is provided with a fixture 11 for adjusting the balance of the device body 2 on the fixing platform 1.

An elastic shaft 12 for improving the tightness of the device body 2 is provided in the fixture 11. The elastic shaft 12 is arranged in the middle of the fixture 11, and a compression spring for improving the effect is wound on the elastic shaft 12. Auxiliary bodies 13 are provided at both ends of the fixture 11. The auxiliary bodies 13 can further improve the fixing strength of the clamping ring 15 on the device body 2.

[0026] The fixture 11 is provided with a clamping ring 15 for limiting the movement of the device body 2. The specifications of the clamping ring 15 are only for a certain model of the device body 2, and each clamping ring 15 needs to be set according to the specifications of the device body 2. The clamping ring 15 is fixedly connected to the auxiliary body 13 through an auxiliary shaft 14. The auxiliary shaft 14 is a connecting component, and the clamping ring 15 is against the device body 2.

[0027] The working principle of the utility model is as follows: two device bodies 2 are placed on the fixing platform 1, and it is ensured that the two device bodies 2 are kept at the same level, and then the clamping ring 15 is completely pressed against the device body 2 by adjusting the fixer 11, and then the threaded rod 6 is rotated to make the drilling end 7 penetrate into the ground, thereby improving the stability of the fixing platform 1.
