[0053] The present application provides a movable and highly integrated automated testing device for testing various performance indicators of a telescopic guide rail, which is helpful in simplifying the testing process.

[0054] See also Figure 1 The automated testing device 1 of the present application includes a main frame 10 and a fatigue and load testing component 20 , a friction resistance testing component 30 and an impact testing component 40 respectively connected to the main frame 10 .

[0055] In this embodiment, the main frame 10 is a rigid structure as a whole, which is used to support the overall structure of the automated testing device 1, fix the fatigue and load testing component 20, the friction resistance testing component 30 and the impact testing component 40, and maintain the relative position relationship between the fatigue and load testing component 20, the friction resistance testing component 30 and the impact testing component 40.

[0056] See also Figure 2 The main frame 10 includes a base plate 11, a support frame 12 and a mounting platform 13. The support frame 12 has a first end 121 and a second end 122. The base plate 11 is fixedly connected to the first end 121 of the support frame 12, and the mounting platform 13 is fixedly connected to the second end 122 of the support frame 12. When the automated testing device 1 is placed on the ground, the first end 121 is closer to the ground than the second end 122. The support frame 12 includes four support bars 123 extending from the first end 121 to the second end 122 and spaced apart from each other. The four support bars 123 are perpendicular to the ground. Impact test assembly 40 (see Figure 1 ) is located in the space between the four support bars 123. That is, the impact test assembly 40 is located between the base plate 11 and the mounting table 13.

[0057] The bottom plate 11 as a whole is a thin plate-like structure of approximately equal thickness, including a first mounting portion 111 and four second mounting portions 112. The first mounting portion 111 is approximately rectangular, and the four second mounting portions 112 extend outward from the four vertex positions of the first mounting portion 111 in a strip shape. The automated testing device 1 also includes a moving assembly 50. The moving assembly 50 is fixedly connected to the surface of the bottom plate 11 away from the support frame 12, so that the bottom plate 11 is located between the support frame 12 and the moving assembly 50. The moving assembly 50 includes four universal wheels 51. The four universal wheels 51 are fixedly connected one by one to the surfaces of the four second mounting portions 112 away from the support frame 12 (i.e., the surfaces facing the ground).

[0058] In other embodiments of the present application, the bottom plate 11 may not include the second mounting portion 112, and the universal wheel 51 may be directly fixedly connected to the surface of the first mounting portion 111 away from the support frame 12. In other embodiments of the present application, the second mounting portion 112 and the universal wheel 51 may be other numbers. In other embodiments of the present application, the automated testing device 1 may not include the moving component 50. In this embodiment, by providing the moving component 50, it is convenient to move the position of the automated testing device 1.

[0059] The mounting platform 13 is a thin plate-like structure with substantially equal thickness at all locations, and has a first surface 131 connected to the support frame 12 and a second surface 132 away from the support frame 12, wherein the first surface 131 is located between the second surface 132 and the support frame 12. The first surface 131 is substantially parallel to the second surface 132, and the first surface 131 and the second surface are substantially rectangular. Figure 1 The fatigue and load test assembly 20 and the friction test assembly 30 are arranged on the second surface 132 of the mounting platform 13. The automated testing device 1 further includes a moving handle 60. The handle 60 is fixedly connected to the second surface of the mounting platform 13, and is convenient for grasping to move the automated testing device 1.

[0060] In this embodiment, the fatigue and load test assembly 20 includes a first counterweight 21 and a first push-pull rod 22. The first push-pull rod 22 is fixedly connected to the surface of the first counterweight 21 away from the mounting platform 13, that is, the first counterweight 21 is located between the first push-pull rod 22 and the mounting platform 13. The first counterweight 21 is a rectangular flat plate structure.

[0061] When fatigue testing is required for the telescopic guide rail 2, the telescopic guide rail 2 is fixed to the second surface 132 of the mounting platform 13 and in contact with the second surface 132, and the first counterweight 21 covers the surface of the telescopic guide rail 2 away from the mounting platform 13 and is connected to the telescopic guide rail 2. The first push-pull rod 22 is connected to the surface of the first counterweight 21 away from the telescopic guide rail 2. When the first push-pull rod 22 is pushed and pulled, the first counterweight 21 is subjected to force and moves synchronously in the same direction as the first push-pull rod 22. By placing counterweight structures of different weights on the surface of the first counterweight 21 away from the telescopic guide rail 2, the performance and life of the telescopic guide rail 2 under various loads can be evaluated.

[0062] Please also read Figure 3 and Figure 4 In this embodiment, the friction test assembly 30 includes a sample fixing platform 31, a clamping structure 32, a sliding structure 33, a pressure structure 34 and a second push-pull rod 35. The clamping structure 32 and the sliding structure 33 are respectively connected to the sample fixing platform 31, and the pressure structure 34 and the second push-pull rod 35 are connected to the sliding structure 33.

[0063] The sample fixing table 31 is formed with a U-shaped groove 311 extending along the first direction X. The U-shaped groove 311 has a first side wall 312, a second side wall 313 and a bottom wall 314. The bottom wall 314 is connected between the first side wall 312 and the second side wall 313, and the first side wall 312 and the second side wall 313 are parallel to each other and perpendicular to the bottom wall 314 respectively.

[0064] The clamping structure 32 includes a servo motor 321 and a clamping member 322 connected to the servo motor 321. The servo motor 321 is located outside the U-shaped groove 311 and on the side of the first side wall 312 away from the second side wall 313. The clamping member 322 is located in the U-shaped groove 311. The clamping member 322 is a rectangular plate-shaped structure as a whole, parallel to the first side wall 312 and the second side wall 313. The servo motor 321 is used to drive the clamping member 322 to translate along the second direction Y in the U-shaped groove 311. The second direction Y is perpendicular to the first side wall 312 and the second side wall 313, respectively.

[0065] When the telescopic guide rail needs to be tested, the telescopic guide rail is placed in the U-shaped groove 311 and between the second side wall 313 and the clamping member 322. During the process of the servo motor 321 driving the clamping member 322 to translate toward the second side wall 313, the clamping structure 32 gradually clamps the telescopic guide rail. When the stress strain gauge (not shown) in the clamping structure 32 reaches the set extrusion pressure, the servo motor 321 stops driving the clamping member 322 to move. After the servo motor 321 stops driving, the telescopic direction of the telescopic guide rail is parallel to the extension direction of the U-shaped groove 311 (that is, the first direction X).

[0066] The sliding structure 33 includes a first slider 331, a second slider 332, a first track member 333 and a second track member 334. The first track member 333 is fixedly disposed on the second side wall 313 and is formed with a first track 335 extending along the first direction X. The first slider 331 is slidably connected to the first track member 333 and can slide along the first track 335. The second track member 334 is fixedly disposed on a surface of the first slider 331 away from the first track member 333. The second track member 334 is formed with a second track 336 extending along a third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y, respectively. The second slider 332 is slidably connected to the second track member 334 and can slide along the third direction Z.

[0067] The pressure structure 34 includes a counterweight platform 341 and a rubber head 342. The counterweight platform 341 is fixedly connected to the surface of the second slider 332 away from the second track member 334. The rubber head 342 is detachably connected to one side of the counterweight platform 341 facing the bottom wall 314 of the U-shaped groove 311.

[0068] The counterweight platform 341 is formed with a receiving groove 343. When the pressure structure is placed in the receiving groove 343, the second slider 332 moves toward the bottom wall 314 in the second track 336, driving the pressure structure 34 to move synchronously until the rubber head 342 abuts against the telescopic track. Based on the gravity of the counterweight structure placed in the counterweight platform 341, the pressure structure 34 applies pressure to the telescopic track.

[0069] The second push-pull rod 35 is fixedly connected to the side of the first slider 331 away from the bottom wall 314. By applying a push-pull force to the second push-pull rod 35 along the first direction X, the first slider 331 can be pushed and pulled to slide in the first track 335 synchronously. When the first slider 331 slides in the first track 335, the second slider 332, the second track member 334 and the pressure structure 34 as a whole also move synchronously along the first direction X.

[0070] Please also read Figure 5 and Figure 6 In this embodiment, the impact test assembly 40 includes an upper fixing plate 41, a lower fixing plate 42, a support column 43, a pulley structure 44, a test table 45, a second counterweight block 46 and a fixing member 47.

[0071] The upper fixing plate 41 and the lower fixing plate 42 are plate-shaped structures and are parallel to each other. The lower fixing plate 42 is fixedly connected to the surface of the bottom plate 11 facing the mounting platform 13. The upper fixing plate 41 is spaced apart and arranged in parallel with the mounting platform 13. The impact test assembly 40 includes four support columns 43, and the four support columns 43 are spaced apart and parallelly connected between the upper fixing plate 41 and the lower fixing plate 42.

[0072] The test bench 45 is sleeved on two of the support columns 43 and can be displaced between the upper fixing plate 41 and the lower fixing plate 42 along the extension direction of the support columns 43. The second counterweight 46 is sleeved on the remaining two support columns 43 and can be displaced between the upper fixing plate 41 and the lower fixing plate 42 along the extension direction of the support columns 43.

[0073] The pulley structure 44 is connected to the upper fixed plate 41, and the two ends are respectively connected to the test bench 45 and the second counterweight 46, and is used to cooperate with the movement of the test bench 45 and the second counterweight 46. In this embodiment, the pulley structure 44 includes a first pulley 441, a second pulley 442 and a wire rope 443. The first pulley 441 and the second pulley 442 are fixedly arranged on the upper fixed plate 41. The wire rope 443 is wound around the first pulley 441 and the second pulley 442, and the two ends are respectively connected to the test bench 45 and the second counterweight 46.

[0074] The fixing member 47 is fixedly connected to the surface of the bottom plate 11 facing the mounting platform 13, and is used to fix the telescopic guide rail 2. When the telescopic guide rail 2 is fixed to the fixing member 47, the telescopic direction of the telescopic guide rail 2 is parallel to the third direction Z, and is connected to the test platform 45, and is telescopic with the displacement process of the test platform 45.

[0075] As described above, the automated testing device 1 of the embodiment of the present application integrates the fatigue and load testing component 20, the friction resistance testing component 30 and the impact testing component 40, and can simultaneously support fatigue testing, load testing, friction resistance testing and impact testing for the telescopic guide rail 2. The process of testing the telescopic guide rail 2 by the automated testing device 1 of the embodiment of the present application is described below.

[0076] The automated testing device 1 of the present application embodiment is used for testing Figure 7 and Figure 8 The telescopic guide rail 2 shown. The telescopic guide rail 2 includes a base 201, a sliding member 202 and a plurality of balls 203 located between the sliding member 201 and the base 201. The sliding member 201 can move relative to the base 201, so that the telescopic guide rail 2 can be telescoped.

[0077] Fatigue testing:

[0078] Fatigue testing is used to evaluate the durability of telescopic guide rails 2 during long-term use. Fig. 9 During the test, the sliding member 201 of the telescopic guide rail 2 is connected to the first counterweight 21, and the first push-pull rod 22 is repeatedly pulled and pulled, so that the first counterweight 21 drives the sliding member 202 of the telescopic guide rail 2 to move relative to the base 201, that is, the telescopic guide rail 2 is repeatedly extended and retracted. The durability of the telescopic guide rail 2 is evaluated by detecting the deformation degree and durability of the ball in the telescopic guide rail 2 after pulling and pulling. Usually, the fatigue of the telescopic guide rail 2 can be tested by comparing the push-pull force before and after the test.

[0079] Load Testing:

[0080] The load test is used to evaluate the performance and stability of the telescopic guide rail 2 under normal or extreme load conditions. During the test, a counterweight structure of a specified weight is placed on the first counterweight block 21 to apply a specified gravity to the telescopic guide rail 2, and then the first push-pull rod 22 is repeatedly pulled to repeatedly extend and retract the telescopic guide rail 2, and the performance and life of the telescopic guide rail 2 under the load are evaluated.

[0081] Friction resistance test:

[0082] Friction testing is used to evaluate the durability and performance of materials or products under friction. Figure 3 and Figure 4 During the test, the telescopic rail is placed in the U-shaped groove 311, and the servo motor 321 drives the clamping member 322 to translate along the second direction Y until the telescopic rail is clamped. After the telescopic rail is clamped, a pressure structure with a specific weight is placed in the counterweight platform 341, so that the second slider 332 drives the pressure structure to move downward along the second track 336 (that is, along the third direction Z) until the rubber head 342 abuts against the telescopic rail 2. The second push-pull rod 35 is pushed and pulled back and forth multiple times along the first direction X. After the pushing and pulling is completed, the friction resistance of the telescopic rail 2 is evaluated by measuring parameters such as friction force, friction coefficient and sample wear.

[0083] Impact test:

[0084] The impact test is to evaluate the performance and reliability of the telescopic guide rail 2 under abnormal push and pull forces. This test usually simulates impact events that may occur in actual use to determine the impact resistance and structural strength of the telescopic guide rail 2. During the test, the telescopic guide rail 2 will be subjected to high-intensity impact in the telescopic direction to simulate various possible working conditions and unexpected situations.

[0085] See also Fig.10 During the test, the base 201 of the telescopic rail 2 is fixed to the fixing member 47, the sliding member 202 of the telescopic rail 2 is connected to the test bench 45, and a second counterweight block 46 of a specific weight is arranged at one end of the steel wire 443. At this time, the telescopic direction of the telescopic rail 2 is parallel to the third direction Z.

[0086] Please refer to Figure 6, press the test bench 45 downward, so that the test bench 45 drives the sliding member 202 of the telescopic guide rail 2 to slide synchronously downward along the third direction Z under the action of the pressing force, that is, the telescopic guide rail 2 shrinks at this time. Under the action of the pressing force on the test bench 45, the pulley structure 44 drives the second counterweight 46 to rise. When the telescopic guide rail 2 shrinks to the limit or the second counterweight 46 rises to the limit, the test bench 45 is released instantly. Due to the gravity of the second counterweight 46, after the test bench 45 is released, the second counterweight 46 falls, and the pulley structure 44 drives the test bench 45 to rise at a high speed under the gravity of the second counterweight 46. At this time, the sliding member 202 of the telescopic guide rail 2 rises synchronously with the test bench 45 at a high speed, and the telescopic guide rail 2 is subjected to a large impact force when the rise stops quickly. It can be judged whether the relevant requirements are met based on the structural integrity and functional performance of the telescopic guide rail 2 after the impact, so as to improve the structural design of the telescopic guide rail, improve the impact resistance and reliability of the telescopic guide rail 2, and ensure that it can work safely and reliably in actual use.

[0087] Environmental life test:

[0088] The material of the telescopic guide rail will undergo some deformation, thermal expansion and contraction, and deformation at different temperatures, because the temperature will accelerate the activation factor and cause aging. Through the calculation of the Arnold model formula, the telescopic guide rail is placed in a high temperature or low temperature environment, and then repeatedly rotated after a certain period of time to observe the deformation and recovery ability of the telescopic guide rail to evaluate its temperature adaptability and stability.

[0089] The automated testing device 1 of the embodiment of the present application can be conveniently pushed into a step-type constant temperature and humidity test chamber by providing a moving component 50 to perform an automated aging test on the telescopic guide rail 2 .

[0090] Test passing criteria:

[0091] 1. The push-pull force remains consistent before and after the test, and there is no jamming or jamming during the extension and retraction process of the telescopic guide rail.

[0092] 2. If the telescopic guide rail is a silent guide rail, there will be no noise before and after the test; if the telescopic guide rail is an ordinary guide rail, the noise before and after the test will be the same.

[0093] 3. During the test, no abnormal conditions such as lubricating oil leakage, metal chips flying, and scratches occurred on the telescopic guide rail.

[0094] 4. After the friction resistance test is completed, the telescopic guide rail has no primer exposed;

[0095] 5. There is no oil leakage in the telescopic guide rail before and after the test, the subjective experience of pushing and pulling is normal, and there is no ball falling, friction iron fragments, etc.

[0096] The above-mentioned automated testing device 1 of the present application comprises a main frame 10 and a fatigue and load testing assembly 20, a friction test assembly 30 and an impact test assembly 40 respectively connected to the main frame 10. The automated testing device 1 has a high degree of integration, so that a single testing device can simultaneously complete fatigue testing, load testing, friction testing and impact testing of the telescopic guide rail 2, which is conducive to reducing manpower, financial resources and time costs.

[0097] In addition, the above-mentioned automated testing device 1 is easy to operate and can be quickly used. It can be combined with a robotic arm to perform automated testing (pulling the first push-pull rod 22 and the second push-pull rod 35, pressing the test bench 45, etc. can all be operated by the robotic arm). The test technique has a small error, all are fixed operations, and the measurement consistency is good. The automated testing device 1 is made of aluminum and galvanized sheet material, with simple usage scenarios, not easy to deform and corrode, high measurement accuracy, and high test smoothness. The space enclosed by the main bracket 10 can be used to place a counterweight, and the universal wheel 51 has a brake pad, so that the automated testing device 1 is stable and does not shake easily.

[0098] In addition, the above-mentioned automatic testing device 1 is easy to install, and the telescopic guide rail 2 is fixed by screw fastening, which indirectly checks the thread stress of the fixing screw.
