Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to a testing machine for detecting the length of a damper. Background Technology

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. Various types of dampers (or shock absorbers) have long been used in industries such as aerospace, aviation, military, artillery, and automobiles to reduce vibration and dissipate energy. During damper production, measurements are required, including the relationship between extension length and tension, and the relationship between extension length and return to equilibrium. In the industry, damper dimensions are typically sampled and inspected. A hydraulic drawing machine is used to stretch and compress the damper to its limit position, and then calipers are used for measurement.

[0003] A search revealed a Chinese utility model patent (authorization announcement number: CN215338878U) that provides a measuring mechanism for damper production, including a support platform. One end of the support platform has a support plate fixedly mounted on it. A fixed base is fixedly mounted on the upper part of the support platform. A first servo motor and a second servo motor are fixedly mounted on the bottom back of the support plate. Both the first and second servo motors have a winding reel at their output ends, and a transmission rope is wound around the winding reel. A guide plate is fixedly mounted on one side of the top of the support platform. A first transmission component and a second transmission component are fixedly mounted on the back and top of the support platform. A third transmission component is fixedly mounted at the end of the guide plate. The transmission rope is sequentially attached to the first transmission component, the second transmission component, and the third transmission component. A tension gauge is connected to the bottom end of the transmission rope, and a fixed hanger is fixedly connected to the bottom end of the tension gauge.

[0004] By adopting the above technical solution, a servo motor drives a winding reel to wind the transmission rope, which is then fixed to both ends of the damper by a fixed hanger and a fixed base. The tension is then measured by a tension gauge on the transmission rope. This existing technology can be used to install and fix various dampers, achieving the function of testing. This makes the testing device widely applicable, and its simple structure allows for simultaneous testing of at least two sets of dampers, which is convenient and fast.

[0005] The aforementioned shortcomings of the existing technology are that the guide rope on the winding reel cannot withstand large tension. When testing a damper with large damping, the guide rope may break, causing equipment damage and potentially even safety accidents. Therefore, it is urgent to improve this shortcoming. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems. This invention provides a testing machine for damper length detection, which has the advantages of being able to test dampers with larger damping and having a more convenient and faster testing method.

The first fixing component and the second fixing component are respectively used to fix the two ends of the damper. A cylinder is provided on the base for driving the guide rail assembly to move, and the cylinder drives the guide rail assembly to reciprocate along the height direction of the upright plate.

[0008] Preferably, the guide rail assembly includes a guide rail, a slider, and a connecting plate. The guide rail is mounted on the upright plate and extends along the height direction of the upright plate. The slider slides in cooperation with the guide rail. The connecting plate is mounted on the slider. The second fixing component is fixedly mounted on the connecting plate.

[0009] Preferably, the upright plate is provided with a sliding groove, the cylinder is disposed on the back of the upright plate, and a connecting rod is installed between the output end of the cylinder and the connecting plate, the connecting rod being slidably engaged in the sliding groove.

[0010] Preferably, the upright plate is provided with a grating ruler, and the connecting rod is equipped with a pointer that cooperates with the grating ruler.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a testing machine for detecting the length of a damper. A cylinder drives a guide rail assembly to reciprocate along the height of a vertical plate, thereby causing the damper to stretch and compress along the height direction. This allows for the detection of the maximum stretching and compression distances of the damper. The cylinder drive enables it to withstand greater forces, and the use of a grating ruler facilitates distance observation. Furthermore, this device has three stations; after pressing the test start button, two additional dampers can be installed and removed, repeating the process cyclically, thus improving testing efficiency.

The height of the connecting plate 63 is adjusted, and then the first end of the damper 4 is installed on the first fixed seat 31. The first end of the damper 4 is fixed by the first pin 32. Then the test button is pressed, and the cylinder 2 is started to move upward. When the damper 4 is stretched to the limit position, the data of the grating ruler 71 is read. Then the cylinder 2 drives the connecting rod 21, the connecting plate 63, the connecting seat 51 and the second fixed seat 52 to move downward. When the damper 4 is pressed down to the limit position, the data of the grating ruler 71 is read. Finally, the cylinder 2 drives the connecting rod 21, the connecting plate 63, the connecting seat 51 and the second fixed seat 52 to move back to the initial installation position of the damper 4.
