[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a toughness testing device for tire production, including a workbench 1, a rotating plate 2, a fixed base 3, and a support frame 4. The workbench 1 has a rotating plate 2 on its top, and fixed bases 3 are symmetrically fixed at both ends of the rotating plate 2. The fixed bases 3 are equipped with clamping mechanisms, and a bidirectional cylinder 9 is installed in the middle of the fixed base 3. The two ends of the bidirectional cylinder 9 are respectively connected to two clamping mechanisms. The support frame 4 is fixedly connected to the back side of the workbench 1, and a compression mechanism is provided on the top of the support frame 4. Two stroller tires are placed on the top of the two fixed bases 3 respectively. The two stroller tires are fixed on the top of the fixed bases 3 by the cooperation of the bidirectional cylinder 9 and the clamping mechanism. Then, the compression mechanism moves downward to compress the stroller tires, causing them to deform. The size of the stroller tire after deformation is measured by a measuring tool, and compared with the original size of the stroller tire to determine whether it is qualified.
[0019] The clamping mechanism includes a first gear 5, a second gear 6, a gripper 7, and a connecting arm 8. The first gear 5 and the second gear 6 are symmetrically hinged to both sides inside the fixed base 3. Grippers 7 are fixedly connected to the outer walls of both the first gear 5 and the second gear 6. The two ends of the bidirectional cylinder 9 are respectively fixedly connected to the connecting arm 8. A pin is fixedly connected to one end of the connecting arm 8. The bottom end of the gripper 7 is provided with a strip groove, and one end of the pin is inserted into the inside of the strip groove.
[0020] The outer walls of the first gear 5 and the second gear 6 mesh with each other. The top of the gripper 7 is fixedly connected to a clamping block. The top of the fixed seat 3 is provided with a pressure bearing seat 10, and the interior of the pressure bearing seat 10 is provided with an arc-shaped groove.
[0021] After the stroller tire is placed on top of the fixing seat 3, the pressure seat 10 supports the stroller tire. The two ends of the bidirectional cylinder 9 drive the connecting arm 8 to move. The connecting arm 8 pulls the gripper 7 on the first gear 5 to rotate through the pin. The pin can slide inside the slot to eliminate the interference between the connecting arm 8 and the gripper 7. The first gear 5 drives the gripper 7 on the second gear 6 to rotate in the opposite direction, so that the two grippers 7 come closer to each other and clamp the stroller tire to fix the stroller tire on top of the fixing seat 3 and prevent it from popping outward under force. After the test is completed, the bidirectional cylinder 9 drives the connecting arm 8 to reset. The connecting arm 8 drives the gripper 7 away from the stroller tire, making it easy for people to remove the stroller tire.
[0022] The extrusion mechanism includes a lifting cylinder 11, a connecting plate 12, and an extrusion disc 13. The lifting cylinder 11 is fixedly installed on the top of the support frame 4. The output end of the lifting cylinder 11 is fixedly connected to the connecting plate 12. The two ends of the connecting plate 12 are symmetrically fixedly connected to the extrusion disc 13. The extrusion disc 13 is parallel to the position of the fixed seat 3. The output end of the lifting cylinder 11 can drive the extrusion disc 13 to move downward through the connecting plate 12, so that the extrusion disc 13 extrudes the stroller tire on the top of the fixed seat 3, causing the stroller tire to deform. The stroller tire is judged to be qualified by measuring the size of the deformed stroller tire and comparing it with the expected size.
[0023] The bottom of the workbench 1 is provided with a drive box 14, and a rotating shaft 16 is rotatably connected inside the drive box 14. The top end of the rotating shaft 16 is fixedly connected to the bottom of the rotating plate 2, and a rotating mechanism is provided inside the drive box 14.
[0024] The rotating mechanism includes a worm gear 17 and a worm wheel 18. The bottom end of the rotating shaft 16 is fixedly connected to the worm wheel 18. The worm gear 17 is rotatably connected to one side of the drive box 14. The outer wall of the worm gear 17 meshes with the outer wall of the worm wheel 18. A motor 15 is fixedly installed on one side of the drive box 14. The output end of the motor 15 is fixedly connected to one end of the worm gear 17. The motor 15 can drive the worm gear 17 to rotate inside the drive box 14. The worm gear 17 meshes with the worm wheel 18, and the worm gear 17 can drive the worm wheel 18 to rotate. The worm wheel 18 is connected to the rotating plate 2 as a whole through the rotating shaft 16 to drive the rotating plate 2 to rotate, so that the rotating plate 2 is in a longitudinal state, driving the fixed seat 3 to load and unload baby stroller tires in a range away from the extrusion plate 13, thereby improving the safety of the detection device.
[0025] The motor 15 is provided with a protective shell on its outer side. The protective shell is detachably connected to one side of the drive box 14 by bolts. The motor 15 is provided with a collision protection strip on its outer side. The collision protection strip and the protective shell can isolate the motor 15 from external objects and prevent direct contact, thus protecting the motor 15.
[0026] The tire toughness testing device places the stroller tire on top of the fixed base 3, where it is supported by the pressure seat 10. The two ends of the bidirectional cylinder 9 drive the connecting arm 8 to move. The connecting arm 8 pulls the gripper 7 on the first gear 5 to rotate via a pin. The pin can slide inside the slot to eliminate interference between the connecting arm 8 and the gripper 7. The first gear 5 drives the gripper 7 on the second gear 6 to rotate in the opposite direction, so that the two grippers 7 move closer to each other and clamp the stroller tire to fix it on top of the fixed base 3, preventing it from popping outward under force. After the test is completed, the bidirectional cylinder 9 drives the connecting arm 8 to reset, and the connecting arm 8 drives the gripper 7 away from the stroller tire, making it easy for people to remove the stroller tire.
