DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Embodiment 1

[0026] like Figure 1 As shown, a tire explosion device for automobile inspection includes a workbench 5, a blasting assembly 6 whose left and right ends are symmetrically fixedly connected to a support frame 4, a feeding assembly 3 is fixedly connected to the rear of the upper end of the workbench 5, a clamping device 2 is slidably connected to the middle of the upper end of the workbench 5, a motor 1 is fixedly connected to the right of the clamping device 2, and a blasting assembly 6 is slidably connected to the front of the upper end of the workbench 5.

[0027] During the implementation of this embodiment, the tire to be tested is first placed on the lower part of the clamping device 2 through the loading assembly 3, and then the tire is lifted and fixed on the clamping device 2. Then the motor 1 can be started to drive the clamping device 2 to rotate backward. The speed of the motor 1 can be controlled to control the speed of tire rotation, thereby expanding the experimental range. Then, the blasting assembly 6 can be used to perform a blasting test on the tire.

[0028] Specifically, in order to reduce the pressure on staff to load materials, refer to Figure 3 In this embodiment, the feeding assembly 3 includes a bidirectional threaded rod 31, a middle portion of the outer surface of the bidirectional threaded rod 31 is rotatably connected to an arc-shaped receiving block 33, and an inclined plate 32 is fixedly connected to the upper rear portion of the outer surface of the arc-shaped receiving block 33;

[0029] For further information, see Figure 3 In this embodiment, the bidirectional threaded rod 31 is rotatably connected to the workbench 5, and the bidirectional threaded rod 31 is threadedly connected to the two slides 22;

[0030] The width of the arc-shaped receiving block 33 is much smaller than the width of the tire, which will not affect the rotation and fixation of the tire. The height of the arc-shaped receiving block 33 is smaller than the height of the tire after fixation, which will not affect the rotation of the tire.

[0031] It can be seen that in specific practice, the initial state of the device is that the two slides 22 are away from each other, which is convenient for installing the tire. At this time, the staff can roll the tire to the upper end of the arc-shaped receiving block 33 through the inclined plate 32 and temporarily place it there to reduce labor pressure. Then, the tire is lifted and the threaded hole for fixing on the tire is put on the fixing rod 23. Then, the two-way threaded rod 31 can be rotated to fix the tire using the clamping device 2. After the test, the two-way threaded rod 31 can be rotated again to make the slides 22 on both sides move away from each other, and the tire can be lifted down and placed on the upper end of the arc-shaped receiving block 33, and then rolled down using the inclined plate 32 again.

[0032] Specifically, in order to expand the range of tire detectable conditions, see Figure 2 In this embodiment, the clamping device 2 includes two slide plates 22, and the upper parts of the two slide plates 22 close to each other are rotatably connected with a turntable 21, the left end of the turntable 21 located on the right is fixedly connected with a plurality of fixing rods 23 in a circular array, and the right end of the turntable 21 located on the left is provided with a plurality of through holes in a circular array, and the outer sides of the two turntables 21 close to each other are fixedly connected with a rubber ring 24;

[0033] For further information, see Figure 2 , in this embodiment, the turntable 21 located on the right is fixedly connected to the motor 1;

[0034] It can be seen that in the practical process of fixing the tire by the clamping device 2, when the bidirectional threaded rod 31 is rotated, the slides 22 on both sides approach each other, and then several fixing rods 23 will pass through the side through holes opened in the turntable 21 on the other side until the turntables 21 on both sides are close to the two sides of the tire. At this time, the bidirectional threaded rod 31 can be continued to be rotated to completely fix the tire, and the rubber rings 24 on both sides can continue to protect the two sides of the tire to avoid friction and wear between the tire and the turntables 21 on both sides. After the fixation is completed, the motor 1 can be started to drive the turntables 21 on both sides to start rotating, thereby driving the tire to start rotating, and then the blasting detection can be continued in cooperation with the blasting assembly 6. During this process, the rotation speed of the motor 1 can be controlled to expand the state range of the tire and improve the range of test detection.

[0035] Specifically, in order to improve the reliability of experimental data, see Figure 4 and Figure 5 In this embodiment, the blasting assembly 6 includes a cylinder 61 and two guide plates 62. The piston rod at the output end of the cylinder 61 is fixedly connected to a sliding member 63, and the upper end of the sliding member 63 is fixedly connected to a cutting assembly 64;

[0036] For further information, see Figure 4 In this embodiment, the sliding member 63 is slidably connected to the workbench 5, and the two guide plates 62 are fixedly connected to the workbench 5;

[0037] For further information, see Figure 5 In this embodiment, the cutting assembly 64 includes a placement block 642, the placement block 642 is fixedly connected to the sliding member 63, a bayonet 643 is slidably connected to the rear end of the placement block 642, and a slide bar 641 is fixedly connected to the left and right ends of the placement block 642, and the two slide bars 641 are slidably connected to the guide plate 62 on the same side;

[0038] It can be seen that when the tire starts to rotate, the cylinder 61 can be started to push the sliding member 63 to move backward quickly, driving the placement block 642 to move backward quickly. During this process, the sliding rods 641 on both sides move close to each other at the end of the guide plate 62 on the same side to maintain the stability of the placement block 642. The placement block 642 also drives the bayonet 643 to move quickly toward the tire during the rapid movement of the tire. During the rapid rotation of the tire, the bayonet 643 will quickly pierce into the inside of the tire to complete the explosion. At this time, the tire is still rotating, which can drive the bayonet 643 to slide out from the inside of the placement block 642, thereby simulating the accidental explosion of the tire during the driving of the vehicle, further improving the realism of the simulation, and improving the authenticity and reliability of the detection data.

[0039] It should be noted that the specific installation method of the motor 1 and the cylinder 61, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
