Description

Technical Field

[0001] This utility model relates to testing equipment for testing the outer diameter and scanning shape of air springs, and involves an infrared emitter, an infrared receiving template, and an infrared conversion imaging system. Background Technology

[0002] As air suspension systems, which use air springs as elastic elements, become increasingly mature, the automotive industry's demand for them is gradually increasing, leading to the rise of the domestic air spring industry. To seize market share, in addition to affordable prices, strict quality control during the production process and the production of products with stable and suitable mechanical properties are key to success.

[0003] The most commonly tested mechanical properties of air springs are the outer diameter of the bladder, load-bearing capacity, and static stiffness. The outer diameter requires measurement using vernier calipers, which can easily lead to two problems: error and safety. Errors may arise during measurement due to the vernier calipers or the experimenter's reading errors. Some products have sloping top or bottom covers, posing a risk of insufficient friction causing the bladder to slide to one side and injure the experimenter (low probability). Some 2B and 3B category products, when inflated to higher pressure, may not maintain balance between the upper and lower halves, tending to squeeze to one side. During static stiffness testing, some C category products, when inflated to higher pressure, may gradually develop a banana-shaped bladder, creating a risk of squeezing and ejecting to one side.

[0004] Therefore, we propose an air spring outer diameter and shape scanning system to solve the problems mentioned above. Utility Model Content

[0008] As a further embodiment of this utility model: the infrared emitter adopts a long strip-shaped infrared emitting lamp, and the protective shell of the infrared emitting lamp is made of metal or plastic as required. Threaded holes are drilled on both sides of the lamp, perpendicular to the horizontal plane, and the lamp is rotated into the screw guide rail of the infrared emitter, so that it can move freely up and down while the screw guide rail rotates.

[0009] As a further embodiment of this utility model: the infrared transmitter guide rail uses an electric motor as the power unit, a conveyor belt and a multi-stage speed-changing gear as the transmission device, and a threaded rod as the main power output.

[0019] The components include: 1. Infrared transmitter; 2. Infrared transmitter rail; 3. Rail frame; 4. Infrared receiver screen; 5. Receiver screen frame; 6. Central control system. Detailed Implementation

[0020] In one embodiment, such as Figures 1-3 As shown, an air spring outer diameter and shape scanning system includes: an infrared emitter 1, an infrared emitter rail 2, a rail frame 3, an infrared receiver screen 4, a receiver screen frame 5, and a central control system 6. The infrared emitter 1 is mounted and positioned on the infrared emitter rail 2. The infrared light emitted by the infrared emitter 1 is a line segment. By moving up and down in the infrared emitter rail 2, the infrared line segment is scanned into an infrared plane, thereby projecting the outer diameter and shape of the air spring to be tested onto the infrared receiver screen 4. The infrared emitter rail 2 is mounted on the infrared receiver screen 4. On the rail frame 3, the central control program 6 controls the operation, gear shifting, and direction changing of the motor on the infrared transmitter guide rail 2, thereby enabling the infrared transmitter 1 to move up and down on the infrared transmitter guide rail 2 at the required speed. A tensioning machine is installed on one side of the rail frame 3, and the infrared receiving screen 4 is installed on the other side of the tensioning machine. If there is a risk of the air spring popping out: 1. The central control system 6 can be used to manually control the pop-out protective frame to ensure the safety of the infrared transmitter 1, its infrared transmitter guide rail 2, and the infrared receiving screen 4; 2. The load value displayed by the tensioning machine control system can be monitored. The system detects sudden changes and risks, triggering the protective frame to pop out. The program can be programmed to scan the normal shape of the air spring's bladder and upload it to the protection system. If the bladder's shape deviates significantly from the normal value during testing, the protection system will automatically trigger, popping out the protective frame. The infrared receiver screen 4 is fixed to the receiver screen frame 5. When the infrared light scans the air spring, the air spring blocks some infrared rays, creating a shadow area with the infrared light directly hitting the infrared receiver screen 4. This shadow area represents the desired air spring shape. After identifying the air spring shape, the infrared receiver screen 4 uploads it to the central control system 6 to generate an air spring diagram, thus obtaining information such as the air spring's outer diameter and shape. The central control system 6 is installed on an office computer and is used to generate the air spring diagram and control the operation of the air spring's outer diameter and shape scanning system. The office computer is located on one side of the receiver screen frame 5. The infrared transmitter 1 can be moved freely up and down on the infrared transmitter guide rail 2 at the desired speed using a mouse. In an emergency, the guide rail frame 3 and receiver screen frame 5 can be actively commanded to activate the protection device, popping out the protective frame to protect the entire system from accidental damage to the air spring.

[0021] like Figure 1As shown, the infrared transmitter 1 uses a long, strip-shaped infrared emitter. The protective shell of the infrared emitter is made of metal or plastic, depending on the requirements. Threaded holes are drilled on both sides, perpendicular to the horizontal plane, and the emitter is rotated into the screw guide rail of the infrared transmitter 1, allowing it to move freely up and down as the screw guide rail rotates. The infrared transmitter guide rail 2 uses an electric motor as the power unit, a conveyor belt, a multi-stage gearbox as the transmission device, and a threaded rod as the main power output. Through the cooperation of the electric motor, conveyor belt, multi-stage gearbox, and threaded rod, it can autonomously select high-speed gears, low-speed gears, and ascending / descending operations, meeting the power operation requirements of the entire system. Both the guide rail frame 3 and the receiver screen frame 5 are constructed from sheet metal panels. The guide rail frame 3 and the receiver screen frame 5 are equipped with active control protection and automatic system judgment protection (1. Automatic protection activated when the system detects a sudden change in the load value; 2. Automatic protection activated when the shape of the scanning spring bladder deviates too much from the set value), providing multiple protection methods to prevent damage to other devices. The infrared receiver screen 4 is a glass screen that receives signals from the infrared transmitter 1 and uploads them to the central control system 6 to draw the shape of the air spring. The central control system 6 is an operation control program: the commands that can be operated through this program are: 1. Control the infrared transmitter to emit infrared rays; 2. Control the guide rail to rise and fall at the required speed to scan the air spring; 3. Process the information from the infrared receiver screen to form an air spring scan image, and process the image to obtain information such as the outer diameter and shape of the air spring; 4. Activate the active protection device to protect the entire system from damage.

[0022] The above embodiment discloses an air spring outer diameter and shape scanning system. An infrared emitter 1 emits infrared rays to the air spring to be tested. The infrared emitter guide rail 2 can be controlled to move the infrared emitter 1 up or down, thereby scanning the air spring. The air spring to be tested is scanned onto the infrared receiving screen 4. The image is uploaded from the infrared receiving screen 4 to the central control system 6. The central control system 6 generates the outer diameter and shape information of the air spring and feeds it back to the computer display screen, so that the experimenter can obtain the required data. The air spring outer diameter and shape scanning system is equipped with a protection system that can pop out a protective plate to protect the infrared receiving screen 4 under specific circumstances.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
