[0002] The shift lever of a freight vehicle needs to use a rubber sleeve, which plays a role in shock absorption and dust prevention at the bottom of the vehicle. Currently, the shock absorption and dust prevention rubber sleeve of an automobile usually uses the rubber elasticity of the telescopic tube-shaped rubber sleeve itself to continuously expand and contract, so that the rubber sleeve can provide dust protection for the automobile shock absorption device in real time. However, during the continuous reciprocating expansion and contraction of the shock absorption and dust prevention rubber sleeve, it is easy to cause a reduction in the tensile capacity.

[0003] Chinese patent application with publication number CN108931425A discloses a tensile strength testing device for the production of fish-scale rubber sleeves, including a bottom plate. On both sides of the top end of the bottom plate, a first motor is fixed. The output shaft of the first motor is connected to a vertically arranged lead screw. At the top ends of the two lead screws, a horizontally arranged top plate is provided, and one end of each lead screw is rotatably connected to the bottom end of the top plate. A horizontally arranged movable plate is rotatably connected to the two lead screws. At the center position of the bottom end of the movable plate, a first cylinder is fixed.

The two clamping devices have the same structure, and the clamping device includes a hollow mounting plate. The device has a simple structure, is convenient for fixing the rubber sleeve, and the fixing is stable and firm. It can also detect rubber sleeves of different specifications and meet the detection of rubber sleeves of different lengths, with high flexibility and strong convenience.

When the inner rotating cylinder 402 and the outer rotating cylinder 403 rotate and cooperate in different ways, the deflection and rotation of the detection rod 415 can be realized.

[0022] In this embodiment: The fully automatic rubber sheath fatigue test device is mainly divided into four parts: an operating table 1, a horizontal movement mechanism 2, a vertical movement mechanism 3, and a detection mechanism 4. When this device is in use, first, the upper and lower ends of the rubber sheath to be tested are respectively fixed to the lower mounting seat 219 and the upper mounting seat 311. Then, the driving motor 216 and the lifting motor 313 are started. When the driving motor 216 drives the linkage ring 204 to rotate, the upper meshing rod 207 travels along the track 202, and its movement will also synchronously drive the connecting frame 214 to move. When the sliding sleeve 206 moves along the track 202, the second moving table 209 will also move relative to the bottom plate 201 in the same trajectory, so as to perform cyclic pulling on the bottom of the rubber sheath in the horizontal direction. When the lifting motor 313 drives the eccentric gear one 305 to rotate, since the output end of the lifting motor 313 is connected to the eccentric position of the eccentric gear one 305, the eccentric gear one 305 will drive the limit top plate 303 to move up and down reciprocally, so as to perform multiple and cyclic pulling on the top of the rubber sheath in the vertical direction.

[0023] Refer to Figures 2-5, the moving direction of the first moving platform 208 is perpendicular to that of the second moving platform 209. Connecting frames 214 facing downward are fixedly connected to both sides of the second moving platform 209. A sliding sleeve 206 is slidably arranged on the sliding arm 205. An upper meshing rod 207 movably arranged in the track 202 is provided at the top of the sliding sleeve 206. A lower meshing rod 215 movably connected to the middle of the connecting frame 214 is provided at the bottom of the sliding sleeve 206.

[0024] In this embodiment: When the driving motor 216 drives the linkage ring 204 to rotate, the upper meshing rod 207 drives the connecting frame 214 to move synchronously when traveling along the track 202. When the sliding sleeve 206 moves along the track 202, the second moving platform 209 also makes the same movement relative to the bottom plate 201, and its trajectory is also a square. When the sliding sleeve 206 moves along one set of right-angled sides on the track 202, the connecting frame 214 drives the second moving platform 209 to slide along the first limiting rail 210, and at this time, the first moving platform 208 remains stationary. When the sliding sleeve 206 moves along the other set of adjacent right-angled sides on the track 202, at this time, the first moving platform 208 slides along the first limiting groove 211, and at this time, the second moving platform 209 remains stationary relative to the first moving platform 208.

[0025] Refer to Figure 1 and Figure 4 , a rotating cavity 203 is opened in the middle of the bottom plate 201. Multiple mounting columns 102 cooperating with the bottom plate 201 are arranged at the top of the operating platform 1. A detecting vertical plate 103 cooperating with the mounting frame 401 is further arranged at the top of the operating platform 1. Multiple support legs 101 are arranged on the outer wall of the operating platform 1.

[0026] In this embodiment: In order to ensure that the linkage ring 204 is rotatably arranged at the bottom of the bottom plate 201, the rotating cavity 203 is opened.

[0027] Refer to Figures 1-5 , a driving motor 216 is further installed on the operating platform 1. A driving wheel 217 is installed at the output end of the driving motor 216. The driving wheel 217 is connected to the linkage ring 204 through a belt 218. The first limiting rail 210 is fixedly arranged at the top of the bottom plate 201. The first limiting groove 211 cooperating with the first limiting rail 210 is opened at the bottom of the first moving platform 208.

[0028] In this embodiment: In order to drive the linkage ring 204 to rotate, so as to drive the rubber sheath to be measured to move through the second moving platform 209, a drive motor 216 structure is designed. In order to ensure that the first moving platform 208 reciprocates along the bottom plate 201 and the second moving platform 209 reciprocates along the first moving platform 208, so as to pull the sheath from multiple angles and in all directions, a limiting rail and a limiting groove structure that cooperate with each other are designed.

[0029] Refer to Figure 2 and Figure 6 , a lower clamping cylinder 220 is further installed on the bottom plate 201 on both sides of the lower mounting seat 219, and an upper clamping cylinder 312 is further installed on the bottom of the upper mounting plate 310 on both sides of the upper mounting seat 311.

[0030] In this embodiment: In order to quickly lock and install the upper and lower ends of the rubber sleeve to be measured, a structure of a lower clamping cylinder 220 and an upper clamping cylinder 312 that cooperate with each other is designed.

[0031] Refer to Figures 6-7 , symmetric sliding columns 302 are fixedly arranged on the top of the fixed seat 301, a limiting top plate 303 is fixedly arranged on the top of the sliding column 302, and the lifting seat 306 is slidably arranged on the sliding column 302; a lifting plate 309 is arranged on the top of the lifting seat 306, and a sliding cavity 304 that cooperates with the lifting plate 309 is opened in the middle of the limiting top plate 303.

[0032] In this embodiment: When the lifting plate 309 drives the limiting top plate 303 to reciprocate up and down, the rubber sheath to be measured can be pulled up and down.

[0033] Refer to Figures 6-7 , an eccentric gear one 305 is movably installed on the outer wall of the fixed seat 301, an eccentric gear two 307 that meshes with the eccentric gear one 305 is installed on the outer wall of the lifting seat 306, the outer sides of the eccentric gear one 305 and the eccentric gear two 307 are movably connected through an engagement frame 308, and a lifting motor 313 connected to the eccentric gear one 305 is installed on the inner wall of the fixed seat 301.

[0034] In this embodiment: During the test operation, when the lifting motor 313 drives the eccentric gear one 305 to rotate, since the output end of the lifting motor 313 is connected to the eccentric position of the eccentric gear one 305, the eccentric gear one 305 will move up and down. And the middle of the lifting seat 306 is movably connected to the eccentric position of the eccentric gear two 307, so the eccentric gear one 305 will drive the lifting seat 306 to reciprocate up and down. In order to ensure that the eccentric gear one 305 and the eccentric gear two 307 always remain in a meshing state, an engagement frame 308 structure is designed.

[0035] Refer to Figures 8-11, a deflection gear one 408 is installed on the outer wall of the inner rotating cylinder 402, a linkage 409 is installed on the outer wall of the outer rotating cylinder 403, the linkage 409 includes a deflection gear two 410 and a first bevel gear 411 fixedly arranged on the top of the deflection gear two 410, and a second bevel gear 414 meshing with the first bevel gear 411 is fixedly installed on the inner wall of the swing frame 413. Symmetrical motor one 417 and motor two 419 are installed at the bottom of the mounting frame 401, a driving gear one 418 meshing with the deflection gear one 408 is installed at the output end of the motor one 417, and a driving gear two 420 meshing with the deflection gear two 410 is installed at the output end of the motor two 419.

[0036] In this embodiment: when the motor one 417 drives the deflection gear one 408 to rotate and the motor two 419 is not started, at this time the swing frame 413 drives the detection rod 415 and the sensor 416 to swing quickly. When the motor two 419 drives the deflection gear two 410 to rotate and the motor one 417 is not started, at this time under the cooperation of the first bevel gear 411 and the second bevel gear 414, the swing frame 413 drives the detection rod 415 and the sensor 416 to swing quickly. When the motor one 417 and the motor two 419 are started synchronously and have the same rotational speed, at this time the swing frame 413 drives the detection rod 415 to rotate quickly. When the motor one 417 and the motor two 419 are started synchronously but have different rotational speeds, complex movement of the detection rod 415 can be realized, so as to quickly monitor the fatigue degree of different positions of the rubber sheath to be measured.

[0039] Working principle of the present invention: When the device is in use, the upper and lower ends of the rubber sheath to be tested are first fixed to the lower mounting seat 219 and the upper mounting seat 311 respectively. Then, the driving motor 216 and the lifting motor 313 are started. When the driving motor 216 drives the linkage ring 204 to rotate, the upper engagement rod 207 moves along the track 202 and synchronously drives the connecting frame 214 to move. When the sliding sleeve 206 moves along the track 202, the second moving table 209 also makes the same movement relative to the bottom plate 201, and its trajectory is also a square, so as to perform cyclic pulling on the bottom of the rubber sheath in the horizontal direction. When the lifting motor 313 drives the first eccentric gear 305 to rotate, since the output end of the lifting motor 313 is connected to the eccentric position of the first eccentric gear 305, the first eccentric gear 305 drives the limit top plate 303 to move up and down reciprocally, so as to perform multiple and cyclic pulling on the top of the rubber sheath in the vertical direction.
