Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, and specifically relates to an air spring dual-station durable fixture. Background Technology

[0002] Air springs used in automobiles can effectively improve passenger comfort. To determine the service life of air springs, fatigue testing is required before they leave the factory. Various fatigue testing instruments are available on the market. For example, CN115452628A discloses a fatigue testing bench for air spring shock absorbers. This bench is driven by two sets of drive motors, which in turn drive eccentric wheels through main and driven pulleys and belts. The two eccentric wheels rotate up and down, mutually assisting each other, and with a relatively small driving force, repeatedly extend and retract the air spring.

[0003] However, the above test bench has the following drawbacks: First, the fixed eccentric wheel makes the lifting range of the test fixed, and it cannot be adjusted to the required lifting range and ensure lifting accuracy; Second, the two sets of drive components waste resources and increase costs; Third, during long-term testing, the belt is prone to damage in actual production, which will increase production costs. Utility Model Content

[0006] A dual-station durable air spring fixture includes an upper connecting pressure plate and multiple sets of clamping components. The upper connecting pressure plate is mounted on the output end of a linear power drive component. Multiple sets of air springs are installed between the upper connecting pressure plate and the multiple sets of connecting components. The deformation direction of the air springs is consistent with the output direction of the linear power drive component.

[0007] As a preferred technical solution, the linear power drive component includes an actuating cylinder.

[0008] As a preferred technical solution, the clamping component includes a base plate and a sliding rod. The bottom end of the air spring is mounted on the base plate, and the sliding rod is vertically mounted on the base plate. The sliding rod is slidably connected to the upper connecting pressure plate.

[0009] As a preferred technical solution, bearings are installed on the upper connecting plate, and the sliding rods and bearings are slidably connected in a one-to-one correspondence.

[0010] As a preferred technical solution, a piston fixing base is installed at the bottom of the air spring, and the piston fixing base is fixedly installed on the base plate.

[0011] As a preferred technical solution, the clamping component includes two sets of sliding rods, and the two sets of sliding rods are respectively installed on both sides of the air spring.

[0012] As a preferred technical solution, an upper air chamber connector is installed at the top of the air spring, and the upper air chamber connector is fixedly installed on the upper connecting pressure plate.

[0013] As a preferred technical solution, the middle part of the upper connecting pressure plate is fixedly connected to the output end of the linear power drive component, and the upper connecting pressure plate is connected to two sets of clamping components, with the two sets of clamping components being symmetrical about the output end of the drive component.

[0014] Beneficial effects

[0015] This device can simultaneously perform fatigue tests on multiple air springs using only one set of drive components, significantly improving testing efficiency and reducing equipment investment and operating costs. The distance between the upper connecting plate and the base plate is determined by the height of the air spring, thus this device can adapt to workpieces of different sizes and types, and can flexibly adjust test parameters such as amplitude.

The upper connecting pressure plate 2 is installed on the output end of the linear power drive component. Multiple sets of air springs 1 are installed between the upper connecting pressure plate 2 and the multiple sets of connecting components. The deformation direction of the air springs 1 is consistent with the output direction of the linear power drive component.

[0023] The air spring 1 is equipped with an upper air chamber connector 3 and a piston fixing base 7 at its top and bottom ends, respectively.

[0024] Preferably, the upper connecting pressure plate 2 is I-shaped, and the middle part of the upper connecting pressure plate 2 is fixedly connected to the output end of the linear power drive component. It includes two sets of clamping components, and the two sets of clamping components are symmetrically installed on both sides of the upper connecting pressure plate 2 about the output axis of the linear power drive component. Multiple sets of upper air chamber connectors 3 are fixedly connected to the upper connecting pressure plate 2, and the piston fixing base 7 is installed on the corresponding clamping components.

[0025] Preferably, the linear drive component is selected as a brake cylinder.

[0027] Preferably, the two sets of sliding rods 5 are symmetrically installed on both sides of the air spring 1.

[0028] Working process: After inputting the required amplitude, start the actuator cylinder. The actuator cylinder drives the upper connecting pressure plate 2 to rise and fall repeatedly.
