Description

TECHNICAL FIELD

[0001] The utility model relates to spring detection equipment field, concretely is a shock absorber spring's detection check machine. BACKGROUND

[0002] The shock absorber spring is a vital component in vehicles, machinery and other equipment, and its performance directly affects the stability, comfort and safety of the equipment. In practical applications, the shock absorber spring is subjected to alternating loads for a long time, and is prone to problems such as fatigue, deformation, and reduced elasticity. Therefore, regular detection and verification of the shock absorber spring are necessary to ensure that its performance meets the requirements, which is of great significance to the normal operation of the equipment and the safety of the users.

[0003] In the prior art, when the shock absorber spring is detected and verified, the shock absorber may not be fixed firmly, which may cause the shock absorber to shake or displace during detection, affecting the accuracy of the detection results. Moreover, the traditional detection equipment may be complex to operate and inefficient when adjusting the position of the shock absorber, or it may be difficult to adjust the shock absorber to an accurate detection position, which cannot meet the precise requirements of different detection items for the position of the shock absorber. Therefore, we propose a detection and verification machine for shock absorber springs to solve the existing problems. SUMMARY

[0004] The utility model discloses a kind of detection and verification machines for shock absorber springs to solve the problems raised in the above background.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of detection and verification machine for shock absorber springs, including detection machine, base, limiting mechanism, shock absorber and adjusting mechanism, the detection machine side is fixedly connected with base, base is fixedly connected with limiting frame on the side away from detection machine, base side is provided with the limiting mechanism of gear transmission, and base is provided with the adjusting mechanism of screw transmission, limiting mechanism is fixedly connected with limiting rod on limiting mechanism, limiting mechanism is detachably provided with shock absorber by limiting rod.

[0006] Preferably, the limiting mechanism includes a cover plate, a fixed frame, a first bevel gear, a rotating rod, a second bevel gear, a guide slot, a guide block, a first threaded rod, a telescopic rod, a limiting plate, and a transmission member. The base side is fixedly connected with the fixed frame, the fixed frame is movably connected with the cover plate, the cover plate is movably connected with the first bevel gear inside the fixed frame, and the fixed frame is provided with a guide slot inside. The guide block is slidably connected in the guide slot, the first threaded rod is movably connected in the guide slot, the guide block is movably connected on the first threaded rod, the rotating rod is fixedly connected on the upper side of the first threaded rod, the second bevel gear is provided on the rotating rod, and the first bevel gear and the second bevel gear are meshed with each other.

[0007] Preferably, a telescopic rod is fixedly connected inside the guide groove, the telescopic rod passes through the fixing frame and is fixedly connected to the limit plate, a transmission component is fixedly connected to one side of the limit plate, and the guide block has a trapezoidal structure, with the guide block and the transmission component cooperating with each other.

[0008] Preferably, the surface of the limiting plate is provided with a gasket, the gasket is made of rubber, and the limiting plate and the top of the shock absorber cooperate with each other.

[0009] Preferably, the side of the cover plate away from the fixed frame cooperates with the limiting frame, and a detection probe is provided on the cover plate, which is connected to the detection machine for signal transmission.

[0010] Preferably, the adjustment mechanism includes a second threaded rod, an adjustment groove, an adjustment block, and a servo motor. The base has an adjustment groove inside, a movable rod connected to the second threaded rod inside the adjustment groove, and a servo motor is provided on one side of the adjustment groove. The output end of the servo motor is fixedly connected to the second threaded rod. An adjustment block is slidably connected inside the adjustment groove. The adjustment block has a threaded structure inside, and the adjustment block and the second threaded rod cooperate with each other. A limit rod is fixedly connected to the upper side of the adjustment block, and the adjustment block is connected to the tail end of the shock absorber through the limit rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the limiting mechanism needs to be operated, the rotating cover plate and the limiting frame cooperate with each other, thereby driving the first bevel gear to rotate. Since the first bevel gear and the second bevel gear mesh with each other, when the first bevel gear rotates, it drives the first threaded rod fixedly connected to it to rotate. When the first threaded rod rotates, the guide block is movably connected to the first threaded rod, causing the guide block to slide in the guide groove. The guide block has a trapezoidal structure. When the guide block moves in the guide groove, it will cooperate with the transmission component. The movement of the guide block drives the limiting plate to move along the direction of the telescopic rod through the transmission component. The surface of the limiting plate is provided with a rubber pad. When the limiting plate moves to the appropriate position, the rubber pad can make close contact with the top of the shock absorber. The presence of the rubber pad increases the friction and also prevents damage to the top of the shock absorber, thereby achieving effective limiting of the top of the shock absorber.

[0013] 2. After the servo motor starts, its output end begins to rotate. Since the output end is fixedly connected to the second threaded rod, it will drive the second threaded rod to rotate in the adjustment groove. Under the action of the thread, the adjustment block moves linearly along the axial direction of the second threaded rod. A limit rod is fixedly connected to the upper side of the adjustment block and is connected to the tail end of the shock absorber through the limit rod. Therefore, when the adjustment block slides linearly in the adjustment groove under the drive of the second threaded rod, it will drive the shock absorber to move together through the limit rod, thereby realizing the adjustment of the position of the shock absorber and adjusting the shock absorber to the precise position required for testing and calibration.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figures 1-4 As shown, the present invention proposes a testing and calibration machine for shock absorber springs, comprising a testing machine 1, a base 2, a limiting mechanism 3, a shock absorber 4, and an adjusting mechanism 5. The base 2 is fixedly connected to one side of the testing machine 1, and a limiting frame 6 is fixedly connected to the side of the base 2 away from the testing machine 1. A gear-driven limiting mechanism 3 is provided on one side of the base 2, and a threaded adjusting mechanism 5 is provided inside the base 2. A limiting rod 7 is fixedly connected to the limiting mechanism 3, and the shock absorber 4 is detachably mounted on the limiting mechanism 3 via the limiting rod 7.

[0021] In an optional embodiment, the limiting mechanism 3 includes a cover plate 301, a fixing frame 302, a first bevel gear 303, a rotating rod 304, a second bevel gear 305, a guide groove 306, a guide block 307, a first threaded rod 308, a telescopic rod 309, a limiting plate 310, and a transmission component 311. The fixing frame 302 is fixedly connected to one side of the base 2. The cover plate 301 is movably connected to the fixing frame 302. The first bevel gear 303 is movably connected to the cover plate 301 inside the fixing frame 302. The fixing frame 302 has a guide groove 306 inside. The guide block 307 is slidably connected to the guide groove 306. The first threaded rod 308 is movably connected to the guide groove 306. The guide block 307 is movably connected to the first threaded rod 308. The rotating rod 304 is fixedly connected to the upper side of the first threaded rod 308. The second bevel gear 305 is provided on the rotating rod 304. The first bevel gear 303 and the second bevel gear 305 mesh with each other.

[0022] In an optional embodiment, a telescopic rod 309 is fixedly connected in the guide groove 306. The telescopic rod 309 passes through the fixing frame 302 and is fixedly connected to the limiting plate 310. A transmission component 311 is fixedly connected to one side of the limiting plate 310. The guide block 307 has a trapezoidal structure and cooperates with the transmission component 311.

[0023] In an optional embodiment, the surface of the limiting plate 310 is provided with a gasket made of rubber, and the limiting plate 310 cooperates with the top of the shock absorber 4.

[0024] In an optional embodiment, the side of the cover plate 301 away from the fixing frame 302 cooperates with the limiting frame 6, and a detection probe is provided on the cover plate 301, which is connected to the detection machine 1 via signal.

[0025] When the limiting mechanism needs to be operated, the rotating cover plate 301 cooperates with the limiting frame 6, thereby driving the first bevel gear 303 to rotate. Since the first bevel gear 303 meshes with the second bevel gear 305, when the first bevel gear 303 rotates, it drives the first threaded rod 308, which is fixedly connected to it, to rotate. When the first threaded rod 308 rotates, the guide block 307 is movably connected to the first threaded rod 308, causing the guide block 307 to slide in the guide groove 306. The guide block 307 has a trapezoidal structure. When the guide block 307 moves in the guide groove 306, it cooperates with the transmission component 311. The movement of the guide block 307 is facilitated by... The transmission component 311 drives the limiting plate 310 to move along the direction of the telescopic rod 309. The surface of the limiting plate 310 is provided with a rubber pad. When the limiting plate 310 moves to the appropriate position, the rubber pad can make close contact with the top of the shock absorber 4. The presence of the rubber pad increases the friction and also prevents damage to the top of the shock absorber 4, thereby achieving effective limiting of the top of the shock absorber 4. At the same time, the detection probe provided on the cover plate 301 is connected to the detection machine 1. The detection probe can perform relevant tests on the shock absorber 4 and transmit the detected signal to the detection machine 1 so as to analyze and verify the performance of the shock absorber spring, etc.

[0026] In an optional embodiment, the adjustment mechanism 5 includes a second threaded rod 501, an adjustment groove 502, an adjustment block 503, and a servo motor 504. The base 2 has an adjustment groove 502 inside. The second threaded rod 501 is connected to a movable rod inside the adjustment groove 502. The servo motor 504 is provided on one side of the adjustment groove 502. The output end of the servo motor 504 is fixedly connected to the second threaded rod 501. The adjustment block 503 is slidably connected inside the adjustment groove 502. The adjustment block 503 has a threaded structure inside. The adjustment block 503 and the second threaded rod 501 cooperate with each other. A limit rod 7 is fixedly connected to the upper side of the adjustment block 503. The adjustment block 503 is connected to the tail end of the shock absorber 4 through the limit rod 7.

[0027] After the servo motor 504 is started, its output end begins to rotate. Since the output end is fixedly connected to the second threaded rod 501, it will drive the second threaded rod 501 to rotate in the adjustment groove 502. Under the action of the thread, the adjustment block 503 moves linearly along the axial direction of the second threaded rod 501. The upper side of the adjustment block 503 is fixedly connected to the limit rod 7, and is connected to the tail end of the shock absorber 4 through the limit rod 7. Therefore, when the adjustment block 503 slides linearly in the adjustment groove 502 under the drive of the second threaded rod 501, it will drive the shock absorber 4 to move together through the limit rod 7, thereby realizing the adjustment of the position of the shock absorber 4, and thus adjusting the shock absorber 4 to the precise position required for testing and calibration.

[0028] The working principle of this utility model is as follows: When using this device, if the limiting mechanism needs to be operated, the rotating cover plate 301 cooperates with the limiting frame 6, thereby driving the first bevel gear 303 to rotate. Since the first bevel gear 303 and the second bevel gear 305 mesh with each other, when the first bevel gear 303 rotates, it drives the first threaded rod 308 fixedly connected to it to rotate. When the first threaded rod 308 rotates, since the guide block 307 is movably connected to the first threaded rod 308, the guide block 307 slides in the guide groove 306. 7 has a trapezoidal structure. When the guide block 307 moves in the guide groove 306, it will cooperate with the transmission component 311. The movement of the guide block 307 drives the limiting plate 310 to move along the direction of the telescopic rod 309 through the transmission component 311. The surface of the limiting plate 310 is provided with a rubber pad. When the limiting plate 310 moves to the appropriate position, the rubber pad can make close contact with the top of the shock absorber 4. The presence of the rubber pad increases the friction and can also prevent damage to the top of the shock absorber 4, thereby achieving effective limiting of the top of the shock absorber 4.

[0029] After the servo motor 504 starts, its output end begins to rotate. Since the output end is fixedly connected to the second threaded rod 501, it will drive the second threaded rod 501 to rotate in the adjustment groove 502. Under the action of the thread, the adjustment block 503 moves linearly along the axial direction of the second threaded rod 501. The upper side of the adjustment block 503 is fixedly connected to the limit rod 7, and is connected to the tail end of the shock absorber 4 through the limit rod 7. Therefore, when the adjustment block 503 slides linearly in the adjustment groove 502 under the drive of the second threaded rod 501, it will drive the shock absorber 4 to move together through the limit rod 7, thereby realizing the adjustment of the position of the shock absorber 4, thereby adjusting the shock absorber 4 to the precise position required for testing and verification. The detection probe set on the cover plate 301 is connected to the detection machine 1. The detection probe can perform relevant tests on the shock absorber 4 and transmit the detected signals to the detection machine 1 so as to analyze and verify the performance of the shock absorber spring, etc.
