Description

Technical Field

[0001] The present invention belongs to the technical field of automotive tire testing, and specifically relates to a tire side stamping experiment device. Background Art

[0002] The wheel is one of the important components of an automobile, and the tire on the wheel mainly plays a role in shock absorption, providing good comfort for the whole vehicle. In the prior art, for the structure of a radial tire, the tread has multiple layers of steel wires, and there is no steel wire or only a single layer of steel wire on the side. This structure of the radial tire determines that the side of the tire is very weak and vulnerable to external force damage. Especially under the extrusion of road protrusions and the rim, it is easy to cause the breakage of the carcass cord, the generation of bulges or even tire blowouts. During the enhanced road test of the tire, due to the large number of road protrusions, it is easy to cause tire bulges; during the use by market customers, there are situations such as driving onto the curb, quickly passing through rough roads, off-roading, etc., and tire bulges also occur frequently.

[0003] Currently, all tests related to tire strength are carried out on the tread, and there is no test device for the tire side. In order to effectively control the quality of the tire side, it is necessary to test the physical properties, durability, and safety performance of the tire side. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a tire side stamping experiment device, including: an operation table, on the top of which there is a lifting frame; a flipping mechanism, the top of which is rotationally connected to the bottom of the lifting frame, and the flipping mechanism is used to place the tire flat and upright; a testing mechanism, the bottom of which is rotationally connected to the bottom of the inner wall of the operation table, and there is a tire placed above the testing mechanism, and the testing mechanism is used to detect the wear resistance and impact resistance of the tire sidewall; a stamping machine, which is installed on the outer wall of the operation table.

[0005] Furthermore, the flipping mechanism includes: a rotating shaft installed at the bottom of the lifting frame, with a cylinder rotatably connected to the bottom of the rotating shaft; a T-shaped shaft installed at the bottom of the cylinder, with a base rotatably connected to the bottom of the T-shaped shaft. Symmetrical positioning holes are provided at the bottom of the T-shaped shaft, and symmetrical telescopic blocks are provided on the outer wall of the base. The flipping mechanism further includes: a drive shaft, the top of which is rotatably connected to the bottom of the base; a support assembly, on the outer wall of which a first telescopic rod is installed. The first telescopic rods are evenly arranged on the outer wall of the drive shaft. The support assembly is used to support the rubber layer and the tire itself and drive them to rotate, so that the support assembly supports the tire from the inside. Then, the T-shaped shaft rotates with the base to place the tire flat on the surface of the testing mechanism. By rotating the testing mechanism to make it rub against the tire surface, the wear resistance of the tire is detected. When it is necessary to simulate the tire during driving, the T-shaped shaft drives the base to rotate 90 degrees, so that the support assembly stands up, and then the tire is also placed upright. The drive shaft drives the tire to rotate to simulate the state of the tire during driving, and then cooperate with the testing mechanism for testing. Through the testing of the tire in two states, the wear resistance and impact resistance of the rubber can be evaluated more comprehensively.

[0006] Furthermore, the testing mechanism includes: a testing table, at the bottom of which a rotating table is provided, and the bottom of the rotating table is rotatably connected to the bottom of the inner wall of the operating table. An arc-shaped conveyor belt is provided on the top of the testing table, which is used to rotate in place on the surface of the tire after the tire stands up; a moving assembly, the bottom of which is slidably connected to the top of the testing table, and two moving assemblies are symmetrically arranged. The testing mechanism further includes: a friction assembly installed on one moving assembly, which is used to perform friction tests on the tire with different sharpness levels; an impact assembly installed on the other moving assembly, which is used to cooperate with a punching machine to test the impact resistance of the tire. When the tire rotates, it contacts the friction assembly, and the impact assembly cooperates with the punching machine to impact the side of the tire, so as to test the impact resistance of the tire. By changing the protrusions in the friction assembly, the sharpness of the object contacting the tire is changed. The impact assembly tests the situation of the tire when encountering a large impact and a sharp object. Through the test simulating an extremely complex environment, the safety performance test result of the tire is obtained.

[0007] Further, the support assembly includes: a sleeve housing which is installed at one end of the first telescopic rod. An airbag is provided on the inner wall of the sleeve housing, and the airbag is used to support the rubber layer of the tire; an arc-shaped rod, on the outer wall of which a motor is provided. The motor is installed on the upper and lower sides of the sleeve housing. The arc-shaped rod is used to support the inner diameter of the tire. The motor drives the arc-shaped rod to rotate, so that the two arc-shaped rods present a larger arc to support and fix the tire from the inner wall of the tire, which is applicable to the test of tires and tires with inner tubes.

[0008] Further, the moving assembly includes: a slider, the bottom of which is slidably connected to the top of the test bench, and a mounting plate is provided on the outer wall of the slider; a connecting frame, one end of which is rotatably connected to the inner wall of the mounting plate, and the other end of the connecting frame is fixedly connected to a second telescopic rod. The second telescopic rod is connected to the friction assembly and the impact assembly, so that the second telescopic rod rotates from the horizontal to the vertical direction, and the friction assembly is brought into contact with the tire surface. Similarly, when the impact assembly is testing, when the second telescopic rod rotates, the connecting plate is placed vertically and close to the tire. The second telescopic rod drives the friction assembly to move up and down to simulate the friction test of the tire by the roadside at different heights.

[0009] Further, the friction assembly includes: a fixing plate, the bottom of which is connected to the outer wall of the second telescopic rod, and a plurality of grooves are evenly formed on the top of the fixing plate; a spiked block, the outer wall of which is rotatably connected to the inner wall of the groove; a special-shaped block, the outer wall of which is rotatably connected to the inner wall of the groove. A support plate is arranged below the special-shaped block, and a sliding plate is installed on the outer wall of the support plate. The outer wall of the sliding plate is slidably connected to the inner wall of the groove, so that the support plate moves away from the concave part of the special-shaped block or the spiked block, thereby ensuring that the special-shaped block and the spiked block can rotate, and further enabling the surfaces of the special-shaped block and the spiked block to be exposed from the inside of the groove and contact the tire. Moreover, the second telescopic rod drives the fixing plate to move up and down, which can simulate the friction positions of the roadside at different heights with the tire, and simulate various extreme situations encountered by the vehicle when driving on the road through various forms, making the test results more comprehensive.

[0010] Furthermore, the impact component includes: a connecting plate, the bottom of the connecting plate is connected to one end of the second telescopic rod, circular holes are symmetrically formed at the top of the connecting plate, the positions of the circular holes correspond to the positions of the punching machine, and guide rods are uniformly arranged at the top of the connecting plate; a moving column, the moving column is placed on the top of the connecting plate, and the inner wall of the moving column is slidably connected to the outer wall of the guide rod; a thorn needle, the thorn needle is installed on the inner wall of the moving column, telescopic columns are uniformly arranged at the top of the moving column, and a baffle is installed at the top of the telescopic column. Initially, it is the baffle that contacts the tire. After testing for a period of time, the telescopic columns retract, causing the sharp thorns to protrude from the baffle, and then under the drive during movement, the tire is impacted again. At this time, it is the sharp thorns that contact the tire surface, which is used to simulate the degree of harm caused by the impact of sharp objects on the tire.

[0011] The beneficial effects of the present invention are as follows: 1. By setting the flipping mechanism in the present invention, when it is necessary to simulate the state of the tire during driving, the T-shaped shaft drives the base to rotate 90 degrees, so that the support component stands up, and then the tire is also placed upright. The drive shaft drives the tire to rotate to simulate the state of the tire during driving, and then cooperate with the testing mechanism for testing. Through the testing of the tire in two states, the wear resistance and impact resistance of the rubber can be evaluated more comprehensively.

[0012] 2. By setting the testing mechanism in the present invention, the tire contacts the friction component during rotation, and the impact component cooperates with the punching machine to impact the side of the tire, so as to test the impact resistance of the tire. By changing the protrusions in the friction component, the sharpness of the object contacting the tire is changed. The impact component tests the situation when the tire encounters a large impact and sharp objects, and the safety performance test results of the tire are obtained through the test simulating an extremely complex environment.

[0013] 3. By setting the friction component in the present invention, the support plate is moved away from the concave parts of the special-shaped block or the spiked block, so as to ensure that the special-shaped block and the spiked block can rotate, and then the surfaces of the special-shaped block and the spiked block are exposed from the inside of the groove and contact the tire. And the second telescopic rod drives the fixed plate to move up and down, which can simulate the friction positions between the side of the road at different heights and the tire. By simulating various extreme situations encountered by the vehicle during driving in multiple forms, the test results are more comprehensive.

[0014] 4. By setting the impact component in the present invention, initially, it is the baffle that contacts the tire. After testing for a period of time, the telescopic columns retract, causing the sharp thorns to protrude from the baffle, and then under the drive during movement, the tire is impacted again. At this time, it is the sharp thorns that contact the tire surface, which is used to simulate the degree of harm caused by the impact of sharp objects on the tire. Description of the Drawings

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0018] Example 1, please refer toFigures 1 - 6 , the present invention provides a technical solution: a tire side stamping experiment device will be described as follows.

[0019] It includes: an operating table 1, on the top of the operating table 1 there is a lifting frame 2; a flipping mechanism 3, the top of the flipping mechanism 3 is rotatably connected to the bottom of the lifting frame 2, and the flipping mechanism 3 is used to place the tire 4 flat and vertically; a testing mechanism 5, the bottom of the testing mechanism 5 is rotatably connected to the bottom of the inner wall of the operating table 1, above the testing mechanism 5 there is a tire 4 placed, and the testing mechanism 5 is used to detect the wear resistance and impact resistance of the tire 4; a stamping machine 6, the stamping machine 6 is installed on the outer wall of the operating table 1.

[0020] At the beginning, the staff places the tire 4 on the flipping mechanism 3, and the flipping mechanism 3 drives the tire 4 to be horizontally placed inside the testing mechanism 5, presses and rubs the tire 4 to simulate and test the wear resistance of the tire 4. Subsequently, the flipping mechanism 3 vertically lifts the tire 4 to simulate the situation when the tire 4 is subjected to friction and impact during driving. Finally, the staff judges the test result of the tire 4.

[0021] The flipping mechanism 3 includes: a rotating shaft 301, the rotating shaft 301 is installed at the bottom of the lifting frame 2, and the bottom of the rotating shaft 301 is rotatably connected to a cylinder 302; a T-shaped shaft 303, the T-shaped shaft 303 is installed at the bottom of the cylinder 302, the bottom of the T-shaped shaft 303 is rotatably connected to a base 304, and symmetrically opened positioning holes 309 are provided at the bottom of the T-shaped shaft 303, and symmetrically arranged telescopic blocks 305 are provided on the outer wall of the base 304; the telescopic blocks 305 can be inserted into the positioning holes 309 to make the connection between the base 304 and the T-shaped shaft 303 more stable. The flipping mechanism 3 further includes: a driving shaft 306, the top of the driving shaft 306 is rotatably connected to the bottom of the base 304; a support assembly 308, on the outer wall of the support assembly 308 there is a first telescopic rod 307, the first telescopic rods 307 are uniformly arranged on the outer wall of the driving shaft 306, and the support assembly 308 is used to support the rubber layer of the tire 4 and the tire 4 itself and drive it to rotate.

[0022] Initially, the T-shaped shaft 303 forms a 90-degree angle with the base 304, causing the support assembly 308 to stand upright. The worker puts the tire 4 on the support assembly 308, and the support assembly 308 supports the tire 4 from the inside. Then the T-shaped shaft rotates with the base 304, and the tire 4 is placed flat on the surface of the test mechanism 5. By rotating the test mechanism 5 to rub against the surface of the tire 4, the wear resistance of the tire 4 is detected. When it is necessary to simulate the tire 4 during driving, the T-shaped shaft drives the base 304 to rotate 90 degrees, so that the support assembly 308 stands upright, and thus the tire 4 is also placed upright. The drive shaft 306 drives the tire 4 to rotate to simulate the state of the tire 4 during driving, and then cooperate with the test mechanism 5 for testing. Through the tests of the tire 4 in two states, the wear resistance and impact resistance of the tire 4 can be evaluated more comprehensively.

[0023] The test mechanism 5 includes: a test bench 502, a turntable 501 is arranged at the bottom of the test bench 502, the bottom of the turntable 501 is rotatably connected to the bottom of the inner wall of the operating table 1, and an arc-shaped conveyor belt 506 is arranged at the top of the test bench 502.

[0024] When the tire 4 is placed horizontally on the test bench 502, when the friction assembly 504 starts and the turntable 501 drives the test bench 502 to rotate, the friction assembly 504 can contact the surface of the tire 4 and generate friction, so that the wear resistance of the tire 4 can be tested. When the tire 4 is vertical, its surface contacts the arc-shaped conveyor belt 506 of the test bench 502, so that the tire 4 can stay in place during rotation. Subsequently, the moving assembly 503 drives the friction assembly 504 to rotate and approach the tire 4, so that the tire 4 contacts the friction assembly 504 during rotation. The impact assembly 505 cooperates with the punching machine 6 to impact the side of the tire 4, so as to test the impact resistance of the tire 4. By changing the protrusions in the friction assembly 504, the sharpness of the object contacting the tire 4 is changed. The impact assembly 505 tests the situation of the tire 4 when encountering a large impact and a sharp object. Through the test simulating an extremely complex environment, the safety performance test result of the tire 4 is obtained.

[0025] Example 2, please refer to Figures 1 - 10, the present invention provides a technical solution: on the basis of Embodiment 1, the support assembly 308 includes: a sleeve 3081, the sleeve 3081 is installed at one end of the first telescopic rod 307, and an airbag 3082 is arranged on the inner wall of the sleeve 3081, and the airbag 3082 is used to support the rubber layer of the tire 4; an arc-shaped rod 3084, an electric motor 3083 is arranged on the outer wall of the arc-shaped rod 3084, the electric motor 3083 is installed on the upper and lower sides of the sleeve 3081, and the arc-shaped rod 3084 is used to support the inner diameter of the tire 4.

[0026] Initially, the worker puts the tire 4 on the sleeve 3081, inflates the airbag 3082, supports the tire 4 from the inside, thereby driving the tire 4 to change its position. When testing a tire 4 with an inner tube, the electric motor 3083 drives the arc-shaped rod 3084 to rotate, so that the two arc-shaped rods 3084 rotate 90 degrees around the electric motor 3083, enabling the arc-shaped rod 3084 to be inserted into the rim of the tire, and supporting and fixing the tire 4 from the rim. It is applicable to test the rubber layer of the tire 4 and the tire 4 with a rim.

[0027] The moving assembly 503 includes: a slider 5031, the bottom of the slider 5031 is slidably connected to the top of the test bench 502, and a mounting plate 5032 is arranged on the outer wall of the slider 5031; a connecting frame 5033, one end of the connecting frame 5033 is rotatably connected to the inner wall of the mounting plate 5032, and the other end of the connecting frame 5033 is fixedly connected with a second telescopic rod 5034, and the second telescopic rod 5034 is connected to the friction assembly 504 and the impact assembly 505.

[0028] When performing a friction test on the sidewall of the tire 4, first, the slider 5031 drives the friction assembly 504 to approach the tire 4, and then the mounting plate 5032 drives the connecting frame 5033 to rotate, so that the second telescopic rod 5034 rotates from the horizontal to the vertical direction and brings the friction assembly 504 into contact with the surface of the tire 4. Similarly, when the impact assembly 505 is tested, when the second telescopic rod 5034 rotates, the connecting plate 5051 is placed vertically and approaches the tire 4, and the second telescopic rod 5034 drives the friction assembly 504 to move up and down to simulate the friction test of the tire 4 by the roadside at different heights.

[0029] The friction assembly 504 includes: a fixing plate 5041, the bottom of the fixing plate 5041 is connected to the outer wall of the second telescopic rod 5034, and a plurality of grooves 5042 are evenly arranged on the top of the fixing plate 5041; a spike block 5043, the outer wall of the spike block 5043 is rotatably connected to the inner wall of the groove 5042; a special-shaped block 5044, the outer wall of the special-shaped block 5044 is rotatably connected to the inner wall of the groove 5042, and a support plate 5046 is arranged below the special-shaped block 5044, and a sliding plate 5045 is installed on the outer wall of the support plate 5046, and the outer wall of the sliding plate 5045 is slidably connected to the inner wall of the groove 5042.

[0030] The spiked block 5043 and the irregular block 5044 respectively simulate the stones and sharp objects on the road surface. When the fixing plate 5041 approaches the tire 4 vertically, the built-in drive in the fixing plate 5041 drives the sliding plate 5045 to move, so that the support plate 5046 moves away from the recesses of the irregular block 5044 or the spiked block 5043, thereby ensuring that the irregular block 5044 and the spiked block 5043 can rotate. Furthermore, the surfaces of the irregular block 5044 and the spiked block 5043 are exposed from inside the groove 5042 to the outside and come into contact with the tire 4. And the second telescopic rod 5034 drives the fixing plate 5041 to move up and down, which can simulate the friction positions between the side of the road at different heights and the tire 4. By simulating various extreme situations that a car encounters when driving on the road in multiple forms, the test results are made more comprehensive.

[0031] The impact component 505 includes: a connecting plate 5051, the bottom of the connecting plate 5051 is connected to one end of the second telescopic rod 5034, circular holes 5052 are symmetrically opened at the top of the connecting plate 5051, the positions of the circular holes 5052 correspond to the position of the punching machine 6, and guide rods 5054 are uniformly arranged at the top of the connecting plate 5051; a moving column 5053, the moving column 5053 is placed on the top of the connecting plate 5051, and the inner wall of the moving column 5053 is slidably connected to the outer wall of the guide rod 5054; a thorn needle 5055, the thorn needle 5055 is installed on the inner wall of the moving column 5053, telescopic columns 5056 are uniformly arranged at the top of the moving column 5053, and a baffle 5057 is installed at the top of the telescopic column 5056.

[0032] When testing the impact performance, the connecting plate 5051 is placed vertically. At this time, the circular holes 5052 on the connecting plate 5051 correspond to the position of the punching machine 6. The punching machine 6 drives the end to approach the moving column 5053 and sleeved with the bottom of the moving column 5053. Subsequently, the punching machine 6 is started to make the moving column 5053 impact towards the tire 4 along the guide rod 5054. Initially, the baffle 5057 is in contact with the tire 4. After testing for a period of time, the telescopic column 5056 retracts, so that the thorns protrude from the baffle 5057, and then under the drive during movement, it impacts the tire 4 again. At this time, the thorns are in contact with the surface of the tire 4, which is used to simulate the degree of harm caused by the impact of sharp objects on the tire 4.

[0033] The specific working process is as follows: Initially, the T-shaped shaft 303 forms a 90-degree angle with the base 304, causing the support assembly 308 to stand upright. The worker puts the tire 4 on the support assembly 308, and the support assembly 308 supports the tire 4 from the inside. Then the T-shaped shaft rotates with the base 304 to place the tire 4 flat on the surface of the testing mechanism 5. By rotating the testing mechanism 5 to rub against the surface of the tire 4, the abrasion resistance of the tire 4 is detected. When it is necessary to simulate the tire 4 during driving, the T-shaped shaft drives the base 304 to rotate 90 degrees, so that the support assembly 308 stands upright, and thus the tire 4 is also placed upright. The drive shaft 306 drives the tire 4 to rotate to simulate the state of the tire 4 during driving. When the tire 4 is placed horizontally on the test bench 502, the friction assembly 504 is activated. When the turntable 501 drives the test bench 502 to rotate, the friction assembly 504 can contact the surface of the tire 4 and generate friction, thereby testing the abrasion resistance of the tire 4. When the tire 4 is vertical, its surface contacts the arc-shaped conveyor belt 506 of the test bench 502, enabling the tire 4 to remain in place during rotation. Subsequently, the moving assembly 503 drives the friction assembly 504 to rotate and approach the tire 4, causing the tire 4 to contact the friction assembly 504 during rotation. The impact assembly 505 cooperates with the stamping machine 6 to impact the side of the tire 4 to test the impact resistance of the tire 4. By changing the protrusions in the friction assembly 504, the sharpness of the object contacting the tire 4 is changed. The impact assembly 505 tests the situation when the tire 4 encounters a large impact and sharp objects. The safety performance test results of the tire 4 are obtained through tests simulating extremely complex environments, and finally the test results of the tire 4 are judged by the staff.
