Description

Technical Field

[0001] The utility model relates to the technical field of automobile tire testing, in particular to a self-repairing film nail puncture testing device. Background Art

[0002] Tire self-repairing film is a polymer composite material coated inside the tire or at a specific location. When the tire is punctured by a sharp object, the polymer composite material will respond quickly and wrap the punctured object, while filling the damaged area to form a sealing layer. Once the punctured object is pulled out, the sealing layer will continue to maintain a sealed state to prevent gas leakage.

[0003] The self-repairing film puncture test usually attaches the self-repairing film to the inside of the tire, and then conducts the self-repairing film test experiment on the tire puncture test device. During the test, the tire puncture test device simulates the force, angle and depth of the tire puncture. By observing and recording the performance changes of the tire before and after the puncture (such as the pressure drop, repair time, etc.), the effect and reliability of the self-repairing film can be evaluated. However, the tire puncture test device requires the use of a whole tire, and the entire device is large in size. The test personnel need to consume a lot of physical strength when installing and removing the tire. Female staff may not be able to conduct the test alone. In addition, the existing tire puncture test device cannot observe the repair process of the self-repairing film inside the tire. It can only judge the performance of the self-repairing film by recording the pressure difference and repair time. It is impossible to specifically discover the shortcomings or potential problems of the self-repairing film, such as too slow repair speed, unstable repair effect, etc., which is not conducive to the R&D team to timely adjust and optimize the design of the self-repairing film and improve the overall performance of the self-repairing film.

[0041] The sealing mechanism 3 includes an upper sealing mechanism 31 and a lower sealing mechanism 32 of a cubic structure. A pressure sensor, a temperature sensor and a humidity sensor are arranged inside the upper sealing mechanism 31. The pressure sensor in the upper sealing mechanism 31 is used to detect the change of the pressure inside the sealing device to ensure the repair effect of the self-repairing film and to evaluate whether the tire can continue to drive. The temperature sensor and humidity sensor in the upper sealing device are used to simulate the humidity and temperature inside the tire in real time and to evaluate the self-repairing effect of the tire under different humidity, temperature and other conditions. Observation windows 311 are arranged on the front and rear sides of the upper sealing mechanism 31. A high-speed camera 7 is arranged on one side of the observation window 311. The high-speed camera 7 can record the self-repairing film at the moment of being punctured and its changes, as well as the details of its repair process through the observation window 311, providing rich basis for subsequent research and development. An inflation port 312 is arranged on the right side of the upper sealing mechanism 31. An inflation pump 8 is arranged on one side of the inflation port 312. The inflation pump 8 fills gas into the sealing mechanism 3 through the inflation port 312 to pressurize it, simulating the state of tire pressure during the driving of the car. The pressure is 2.3×10 5 Pa. A circular groove is provided at the bottom of the upper sealing mechanism 31, a protrusion matching the groove of the upper sealing mechanism 31 is provided at the top of the lower sealing mechanism 32, and a sealing ring is provided at the connection between the upper sealing mechanism 31 and the lower sealing mechanism 32 to ensure the airtightness of the connection between the upper sealing mechanism 31 and the lower sealing mechanism 32. A movable plate 313 is fixedly provided on the left side of the upper sealing mechanism 31.

[0042] The adjusting mechanism 5 is arranged on the left side of the sealing mechanism 3, and includes a guide plate 52 matching the movable plate 313, and slide grooves are arranged on both sides of the movable plate 313. Slide rails matching the slide grooves of the movable plate 313 are arranged on both sides of the guide plate 52. The guide plate 52 is perpendicular to the horizontal plane, and a support plate 53 is arranged on the left side of the guide plate 52. The left side of the support plate 53 is arranged in a triangular structure to ensure the stability of the support of the guide plate 52. The bottom of the support plate 53 and the guide plate 52 are both provided with pads 56, and the pads 56 are symmetrically distributed along the middle of the guide plate 52 to ensure the accuracy of the up and down movement of the upper sealing mechanism 31. A motor support plate 53 is provided on the top of the support plate 53 and the guide plate 52, and an adjustment motor 51 is provided on the motor support plate 53. The adjustment motor 51 is located in the middle position above the guide plate 52. The output end of the adjustment motor 51 is connected to a ball screw 54 through a coupling. The ball screw 54 is threadedly connected to the moving plate 313. When the adjustment motor 51 is started, the ball screw 54 is driven to rotate, thereby driving the upper sealing mechanism 31 to move up and down. A brake system is added to the adjustment motor 51 to prevent the ball screw 54 from failing and other unexpected dangers. Limit blocks 55 are respectively provided at the upper and lower ends of the ball screw 54. The limit blocks 55 can ensure the safety of the mechanism when obstacles occur in the adjustment motor 51 or the ball screw 54.

[0043] The fastening mechanism 6 is arranged on the right side of the sealing mechanism 3, and includes a fastening base 61 arranged adjacent to the upper sealing mechanism 31. A caliper 62 is rotatably connected in the fastening base 61. The left side wall of the caliper 62 is close to the upper sealing mechanism 31, and the bottom of the caliper 62 is connected to the fastening base 61 through a rotating shaft 68. A fastening motor 63 is arranged on the right side of the fastening base 61, and a motor pad 69 is arranged at the bottom of the fastening motor 63. The motor pad 69 makes up for the height deficiency of the fastening motor 63. The output end of the fastening motor 63 is connected to a transmission screw 64 through a coupling. The other end of the transmission screw 64 is arranged inside the fastening base 61. A slider 65 is threadedly connected to the transmission screw 64. A limit rod 66 is arranged on the upper part of the slider 65. The other end of the limit rod 66 penetrates the fastening base 61 and is aligned with the limit hole 621 at the bottom of the caliper 62. When the fastening motor 63 is started, it drives the transmission screw 64 to rotate, controls the slider 65 to move left and right, and then controls the limit rod 66 to move left and right. When the limit rod 66 enters the limit hole 621, the position of the caliper 62 is fixed, and the caliper 62 tightly fits the upper sealing mechanism 31 and the lower sealing mechanism 32 together to prevent the upper sealing mechanism 31 from tipping upward under great pressure. When the limit rod 66 is separated from the limit hole 621, the upper sealing mechanism 31 moves upward under the drive of the adjustment mechanism 5, and the caliper 62 moves in an arc around the rotating shaft 68 to separate from the upper sealing mechanism 31. The upper sealing mechanism 31 loses the restriction of the caliper 62 and moves upward smoothly. A spring 67 is arranged between the caliper 62 and the fastening base 61. After the upper sealing mechanism 31 is separated from the caliper 62, the caliper 62 returns to its initial position under the action of the spring 67.

[0044] The caliper 62 is a "7"-shaped structure as a whole. The protrusion above the caliper 62 can tightly fix the upper sealing mechanism 31 to prevent the upper sealing mechanism 31 from flying up and affecting the normal progress of the experiment. An upper inclined surface 622 is provided at one end of the top of the caliper 62 close to the upper sealing mechanism 31. The upper inclined surface 622 facilitates the upper sealing mechanism 31 to move downward smoothly and fit with the lower sealing mechanism 32. A lower inclined surface 623 is provided at one end of the bottom of the caliper 62 close to the upper sealing mechanism 31. The lower inclined surface 623 can ensure that when the caliper 62 makes an arc motion around the rotating shaft 68, the bottom of the caliper 62 does not touch the side wall of the upper sealing mechanism 31, thereby hindering the movement of the caliper 62. A limiting hole 621 corresponding to the limiting rod 66 is provided at the bottom of the right side wall of the caliper 62.

[0045] The flip mechanism 4 includes an upper plate 47 arranged on the horizontal plane of the top of the frame 1. The upper plate 47 is arranged horizontally. The sealing mechanism 3, the adjustment mechanism 5, the fastening mechanism 6, the high-speed camera 7 and the air pump 8 are arranged on the upper plate 47. The lower sealing mechanism 32 is arranged in the upper plate 47. A rotating shaft 48 is arranged on one side of the upper plate 47. The upper plate 47 is hinged to the frame 1 through the rotating shaft 48. A supporting plate 53 is arranged below the upper plate 47. The supporting plate 53 is arranged parallel to the upper plate 47. The front and rear width of the supporting plate 53 is greater than that of the upper plate 4. 7. A flip motor 41 is arranged in the middle position of one side of the support plate 53. The output end of the flip motor 41 is connected to a transmission shaft 43 through a coupling. The front and rear ends of the transmission shaft 43 are fixedly connected to a first connecting rod 44. Two bearing seats 42 are arranged between the front and rear first connecting rods 44. The bearing seats 42 are close to the adjacent first connecting rods 44. The transmission shaft 43 passes through the front and rear bearing seats 42. The other end of the first connecting rod 44 is rotatably connected to a second connecting rod 45. The other end of the second connecting rod 45 is rotatably connected to the middle position of the side of the upper plate 47. The flip motor 41 is started to drive the transmission shaft 43 to rotate. The rotation of the transmission shaft 43 causes the first connecting rod 44 to rotate with the transmission shaft 43 as the center of the circle. The rotation of the first connecting rod 44 further drives the second connecting rod 45 to rotate, so that the upper plate 47 rotates with the rotating shaft 48 as the center of the circle, so that the lower sealing mechanism 32 on the upper plate 47 forms different angles with the horizontal plane, and changes the piercing angle of the self-repairing film and the tire material in the sealing mechanism 3.

[0046] The piercing mechanism 2 is arranged inside the frame 1, below the flip mechanism 4, and includes a cylinder 24 vertically arranged below the lower sealing mechanism 32. A three-jaw chuck 25 is arranged at the telescopic end of the cylinder 24, and a tungsten steel needle 26 is arranged in the three-jaw chuck 25. A pressure sensor is arranged below the three-jaw chuck 25. The pressure sensor can detect the pressure change trend and the final piercing pressure of the tire material and the self-repairing film during piercing, which is used for data recording and summary, and is convenient for subsequent analysis. A square hole is arranged on the support plate 53 above the three-jaw chuck 25, and the area of ​​the square hole is larger than the cross-sectional area of ​​the cylinder 24. A support platform 27 is arranged at the bottom of the cylinder 24, and the support platform 27 reduces the distance between the cylinder 24 and the lower sealing mechanism 32. An air pump 23 for providing gas to the cylinder 24 is arranged on one side of the cylinder 24, and the air pump 23 is connected to the piercing motor 21 through the reduction box 22. The piercing motor 21 is started, and the speed and torque are adjusted through the reduction box 22 to provide power for the movement of the cylinder 24. The three-jaw chuck 25 firmly clamps the tungsten steel needle 26 to ensure that it remains stable during the piercing process. The air pump 23 is started to provide compressed air to the cylinder 24. The piston of the cylinder 24 pushes the tungsten steel needle 26 from bottom to top under the pressure, and pierces the tire surface at a preset speed and force to complete the piercing operation. After the piercing is completed, the cylinder 24 is reversed by the air pump 23, and the piston returns to its position, and the tungsten steel needle 26 is pulled out of the tire material. The piercing motor 21, the reduction box 22, the cylinder 24, the air pump 23, the three-jaw chuck 25 and the tungsten steel needle 26 work together to achieve a high-precision piercing operation.

[0047] The working process of the utility model is:

[0048] The self-repairing film is attached to the tire material, and the tire material attached with the self-repairing film is placed on the lower sealing mechanism 32. The adjustment mechanism 5 controls the upper sealing mechanism 31 to move downward along the upper inclined surface 622 of the caliper 62. Under the action of the upper sealing mechanism 31, the caliper 62 moves in an arc around the rotating shaft 68. When the upper sealing mechanism 31 moves to fit tightly with the lower sealing mechanism 32, a sealed space is formed inside the upper sealing mechanism 31 and the lower sealing mechanism 32. The caliper 62 returns to its initial position under the action of the elastic force of the spring 67. The bottom of the "7"-shaped protrusion above the caliper 62 is close to the top of the upper sealing mechanism 31. The fastening motor 63 is started, and the control limit rod 66 is inserted into the limit hole 621 at the bottom of the caliper 62 to fix the position of the caliper 62, and the upper sealing mechanism 31 is firmly close to the lower sealing mechanism 32. At this time, the air pump 8 presses air into the sealing mechanism 3 through the inflation port 312 on the right side of the upper sealing mechanism 31, so that the pressure inside the sealing mechanism 3 reaches 2.3×10 5 Pa, simulates the tire pressure during normal driving.

[0049] The flipping motor 41 controls the upper plate 47 to rotate around the rotating axis 68, and the sealing mechanism 3 on the upper plate 47 flips together with the upper plate 47, so that the repairable film in the sealing mechanism 3 changes its angle as the upper plate 47 rotates, and the repairable film forms different angles with the horizontal plane. The tungsten steel needle 26, under the power of the piercing motor 21, quickly reaches a preset speed and pierces into the repairable film from different angles at a preset speed to observe and record its repair process.
