Description

Technical Field

[0001] This invention relates to the field of tire technology, and in particular to a detection device and control method for tire internal support structures. Background Technology

[0002] The design of automobile tires has gradually shifted towards tubeless structures, which allow the tire to be directly mounted to the rim, simplifying the tire structure. This simplification not only makes the tire structure more streamlined but also improves performance. Based on the tubeless tire design, further technological innovations have enabled the development of various specialty tires. Among these specialty tires, run-flat tires have attracted much attention due to their wide range of applications. A typical construction of a run-flat tire involves mounting a ring-shaped support structure on the rim. This structure provides necessary support when the tire loses pressure, ensuring safe driving even in the event of tire depressurization or blowout.

[0003] The typical structure of a tire's inner support is an interlocking arc-shaped block structure in the circumferential direction. Abnormalities during the molding process of the tire's inner support can lead to dimensional inaccuracies and structural strength issues. Due to the complexity of the structure, current testing methods for these two aspects are still primarily manual, which is inefficient and makes online testing impossible. Summary of the Invention

[0004] The main objective of this invention is to provide a detection device and control method for tire internal support structures, aiming to solve the problem that due to the complexity of the tire internal support structure, the current detection method is still manual, which is inefficient and cannot achieve online testing.

[0005] To achieve the above objectives, the present invention provides a detection device for a tire inner support body, wherein the tire inner support body is provided with a plurality of structural holes spaced apart, and the detection device includes: Active delivery component; The receiving platform, corresponding to the output end of the active conveying component, is provided with multiple working holes with a projected area covering and larger than the structural holes. The lifting assembly includes a first drive with its output end at the top and a lifting platform disposed at the output end of the first drive. The lifting platform is provided with multiple support columns corresponding to the working hole. The support columns are arranged sequentially from top to bottom as guide sections, fixing sections and support sections that are interconnected and whose projected areas gradually increase and are nested. The shape of the fixing section is consistent with and matches the structural hole. The testing unit includes a pressure output unit and a pressure testing unit arranged opposite to each other. The pressure output unit includes an output base and a second drive installed on the output base. The output end of the second drive is connected to a pressure head. The pressure testing unit includes a testing base and a pressure sensing component installed on the testing base. The outer wall of the pressure sensing component is provided with a sample position that has a first pressure sensing part on the inner side and is arc-shaped. When the first drive moves upward, it transfers the tire inner support body on the receiving platform to the sample position. When the second drive extends, the pressure head clamps the tire inner support body with the sample position.

[0006] Furthermore, a second pressure sensing unit is provided on the portion of the pressure head corresponding to the inner support body of the tire.

[0007] Furthermore, the detection device also includes a rear conveying component arranged in the same direction as the active conveying component along its length. The rear conveying component includes a rear conveying base, a rear conveying part, and a third drive. The rear conveying part is disposed on the rear conveying base, and the third drive drives the rear conveying base to reciprocate along its length, thereby entering and exiting between the receiving platform and the pressure sensing component.

[0008] Furthermore, the pressure sensing component is detachably mounted on the test base, and the pressure head is detachably mounted on the second drive.

[0009] Furthermore, the output base is connected to the test base.

[0010] Furthermore, the active delivery component restricts and clamps the inner support of the tire during operation.

[0011] Furthermore, the upper surface of the support section is provided with an annular third pressure sensing element.

[0012] The present invention also provides a control method applied to the above-mentioned detection device for tire inner support, comprising: S1. Control the first drive to drive the lifting platform to the height of the sample position; S2. After controlling the second drive to extend and clamp the tire inner support body with the sample position through the pressure head, control the first drive to drive the lifting platform to a position lower than the receiving platform. S3. Control the second drive output with a preset pressurization curve; S4. Receive the first real-time sensing data sent by the first pressure sensing unit, and determine the performance of the tire inner support body based on the first real-time sensing data.

[0013] Furthermore, an annular third pressure sensing element is provided on the upper surface of the support segment, and step S1 is followed by: Receive second real-time sensing data from multiple third pressure sensing units; Based on the relationship between the second real-time sensing data and the preset comparison data, it is determined whether the tire internal support is properly supported.

[0014] Furthermore, a second pressure sensing unit is provided on the portion of the pressure head corresponding to the inner support of the tire, and step S2 is followed by: The system receives third real-time sensing data sent by the second pressure sensing unit and determines the clamping state of the tire inner support body based on the third real-time sensing data.

[0015] The step S4 is followed by: The system receives third real-time sensing data sent by the second pressure sensing unit and determines the performance of the tire internal support based on the third real-time sensing data.

[0016] The beneficial effects of this invention are as follows: This invention provides a detection device and control method for tire inner support bodies. Multiple working holes on the receiving platform provide a basis for the alignment of the tire inner support body and the operation of the lifting platform. During the lifting platform's ascent, the guide section first adapts to the tire inner support body to be tested, the fixing section then forms an accurate fit with the structural holes of the tire inner support body, and the support section finally provides over-support, thus enabling the tire inner support body to be supported and lifted to the sample position in an accurate posture. When the tire inner support body is in the upper position, the pressure head clamps the tire inner support body with the sample position when the second drive extends. At this time, the sensing data obtained on the first pressure sensor can reflect the accuracy of the structural dimensions and structural strength performance of the tire inner support body; ultimately achieving an accurate, efficient, and online measurement process.

[0023] Reference Figures 1 to 6 In one embodiment of the present invention, a detection device for a tire inner support body is provided, wherein the tire inner support body 010 is provided with a plurality of structural holes 011 spaced apart, including: Active transmission component 100; The receiving platform 200 corresponds to the output end of the active conveying component 100. The receiving platform 200 is provided with multiple working holes 210 whose projected area covers and is larger than the structural holes 011. The lifting assembly 300 includes a first drive 310 with its output end at the top and a lifting platform 320 disposed at the output end of the first drive 310. The lifting platform 320 is provided with a plurality of support columns 321 corresponding to the working hole 210. The support columns 321 are arranged from top to bottom as interconnected and nested guide sections 322, fixing sections 323 and support sections 324 with gradually increasing and nested projected areas. The shape of the fixing section 323 is consistent with and matches the structural hole 011. The testing unit includes a pressure output unit 410 and a pressure testing unit 420 arranged opposite to each other. The pressure output unit 410 includes an output base 411 and a second drive 412 mounted on the output base 411. The output end of the second drive 412 is connected to a pressure head 413. The pressure testing unit 420 includes a testing base 421 and a pressure sensing component 422 mounted on the testing base 421. The outer wall of the pressure sensing component 422 is provided with a sample position 423 that has a first pressure sensing part 424 on its inner side and is arc-shaped. When the first drive 310 drives upward, it transfers the tire inner support 010 on the receiving platform 200 to the sample position 423. When the second drive 412 extends, the pressure head 413 and the sample position 423 clamp the tire inner support 010.

[0024] In existing technologies, when abnormalities occur during the molding process of the tire inner support, the accuracy of the structural dimensions and the structural strength performance may also be abnormal. Due to the complexity of the structure, the current method for testing these two aspects is still manual, which is inefficient and makes online testing impossible.

[0025] The tire inner support body detection device provided by this invention is used to detect the tire inner support body 010. The tire inner support body 010 has multiple structural holes 011 spaced apart. It should be noted that the tire inner support body 010 in this invention does not refer to the entire body after forming a ring structure. In actual use, multiple tire inner support bodies 010 need to be assembled and combined in the circumferential direction of the wheel hub to complete the operation. The structural holes 011 on the tire inner support body 010 enhance the elasticity of the tire inner support body 010 without compromising the overall structural strength, thus improving the performance of the tire inner support body 010 after a tire blowout. The structural holes 011 can be through holes or blind holes, depending on the design.

[0026] The testing device includes an active conveying component 100, a receiving platform 200, a lifting component 300, and a testing work section, enabling online monitoring.

[0027] The active conveying assembly 100 actively conveys the tire inner support 010 to be inspected. For example, the active conveying assembly 100 is a conveying roller with a drive source, thereby stably conveying the tire inner support 010. The active conveying assembly 100 may also be equipped with a position limiting structure corresponding to the tire inner support 010, thereby reducing the possibility of abnormal position of the tire inner support 010 during the transfer process.

[0028] The receiving platform 200 corresponds to the output end of the active conveying component 100. The tire inner support 010, which exits from the output end of the active conveying component 100, is transferred to the receiving platform 200. The receiving platform 200 can also be provided with limiting structures (such as baffles) in the width direction corresponding to the tire inner support 010. The receiving platform 200 is provided with multiple working holes 210 corresponding to multiple structural holes 011, with a projected area covering and larger than the structural holes 011. The working holes 210 provide a basis for the subsequent operation of the lifting component 300 and further provide a basis for locking the position of the tire inner support 010. The positions of the multiple working holes 210 need to be adapted to the multiple structural holes 011 of the tire inner support 010. When the tire inner support 010 is transferred from the active conveying component 100 to the receiving platform 200, the multiple structural holes 011 on the tire inner support 010 are approximately aligned with the working holes 210 on the receiving platform 200. The abnormal position of the tire inner support 010 during the transfer process may be due to the unique structure of the tire inner support 010, which prevents precise positioning, or the active conveying component 100, which cannot achieve precise positioning from its working angle. The receiving platform 200 can be equipped with an image recognition device or an infrared screen to monitor whether the tire inner support 010 has reached the appropriate position and control the start and stop of the active conveying component 100.

[0029] The lifting assembly 300 includes a first drive 310 with its output end at the top and a lifting platform 320 disposed at the output end of the first drive 310. During operation, the first drive 310 raises and lowers the lifting platform 320 in the vertical direction. Multiple support columns 321 are disposed on the lifting platform 320 corresponding to the working hole 210. From top to bottom, the support columns 321 are interconnected and nested, consisting of a guide section 322, a fixing section 323, and a support section 324, all with progressively increasing projected areas. The shape of the fixing section 323 matches the shape of the structural hole 011. The cross-section of the guide section 322 is smaller than that of the structural hole 011. Therefore, when the position of the inner tire support 010 deviates to a certain extent, during the ascent of the lifting platform 320, the guide section 322 first adapts to the inner tire support 010 under test. The guide section 322 can still correspond to the structural hole 011 of the inner tire support 010. The guide section 322 can be a tapered structure relative to the fixed section 323, or a chamfered structure of the fixed section 323, depending on whether it can guide the movement. When the lifting platform 320 continues to rise, the fixed section 323 on the support column 321 engages with the structural hole 011 of the inner tire support 010. If the inner tire support 010 does not have a large dimensional abnormality, the position of the inner tire support 010 can be accurately determined. At this time, the lifting platform 320 continues to rise, and the support section 324 contacts the inner tire support 010, thereby supporting and lifting the inner tire support 010 in an accurate posture. It should be noted that, in order to ensure the accurate positioning of the tire inner support 010 on the lifting platform 320, the first drive 310 can control the lifting platform 320 to vibrate vertically during the engagement process, thereby assisting the tire inner support 010 in accurate positioning. The power source for the first drive 310 can be pneumatic, hydraulic, or electric motor driven.

[0030] The testing unit includes a pressure output unit 410 and a pressure testing unit 420 arranged opposite to each other. The pressure output unit 410 and the pressure testing unit 420 can be respectively positioned at opposite ends of the receiving platform 200 in the width direction to complete the work; their specific positions can be set and adjusted according to the subsequent working process. The pressure output unit 410 includes an output base 411 and a second drive 412 mounted on the output base 411. The output end of the second drive 412 is connected to a pressure head 413. The second drive 412 provides the pressure required for testing the tire inner support body 010. The power source for the second drive 412 can be pneumatic, hydraulic, or electric. The pressure head 413 ensures that the pressure is applied correctly and stably to the tire inner support body 010.

[0031] The pressure testing unit 420 includes a test base 421 and a pressure sensing assembly 422 mounted on the test base 421. The outer wall of the pressure sensing assembly 422 has an arc-shaped sample position 423, and the inner side of the sample position 423 has a first pressure sensing unit 424. The first pressure sensing unit 424 can be multiple independent pressure sensors or a single sheet-like pressure sensor, depending on whether it can monitor pressure over a large range. The operating type of the first pressure sensing unit 424 can be various, such as resistive, capacitive, or piezoelectric, depending on whether it can accurately perform pressure detection over a large area. The pressure head 413 corresponds to the inner side of the tire inner support 010 (the side in contact with the wheel hub), and the sample position 423 corresponds to the outer side of the tire inner support 010 (the supporting side).

[0032] The work process: The tire inner support 010, which exits from the output end of the active conveying component 100, is transferred to the receiving platform 200, and the multiple structural holes 011 on the tire inner support 010 are roughly aligned with the working holes 210 on the receiving platform 200.

[0033] During the ascent of the lifting platform 320, the guide section 322 first mates with the inner support body 010 of the tire under test. As the lifting platform 320 continues to rise, the fixing section 323 on the support column 321 engages with the structural hole 011 of the inner support body 010. With the lifting platform 320 continuing to rise, the support section 324 contacts the inner support body 010, allowing the inner support body 010 to be accurately supported and lifted to the sample position 423. At this point, the second drive 412 extends its pressure head 413 to clamp the inner support body 010 with the sample position 423. The second drive 412 provides the set pressure, which is applied to the inner support body 010 through the pressure head 413. The sensor data obtained by the first pressure sensor 424 reflects the accuracy of the structural dimensions and structural strength performance of the inner support body 010.

[0034] For example, by comparing the data at each point of the first pressure sensor 424 (not just the data at the last clamping time, but also the real-time data during the clamping process) with the pre-stored detection standard data, if there is a large deviation in the values ​​at each position, it can be determined that the size is abnormal, which causes abnormal contact between the tire inner support 010 and the first pressure sensor 424.

[0035] For example, if the maximum pressure is provided by the second drive 412 for a certain period of time, and the sensing data of the first pressure sensing unit 424 fluctuates, it can be determined that the structural strength performance of the tire inner support 010 is abnormal.

[0036] In summary, the multiple working holes 210 on the receiving platform 200 provide a foundation for the alignment of the tire inner support 010 and the operation of the lifting platform 320. During the ascent of the lifting platform 320, the guide section 322 first adapts to the tire inner support 010 to be tested, the fixing section 323 then forms an accurate fit with the structural hole 011 of the tire inner support 010, and the support section 324 finally provides over-support, so that the tire inner support 010 can be supported and lifted to the sample position 423 in an accurate posture. When the tire inner support 010 is in the upper position, when the second drive 412 extends, the pressure head 413 clamps the tire inner support 010 with the sample position 423. At this time, the sensing data obtained on the first pressure sensing unit 424 can reflect the accuracy of the structural dimensions and structural strength performance of the tire inner support 010, thus achieving an accurate, efficient, and online measurement process.

[0037] In one embodiment, the pressure head 413 is provided with a second pressure sensing unit corresponding to the portion of the tire inner support 010.

[0038] In this embodiment, the data from the second pressure sensor can indicate whether the pressure output unit 410 is correctly coupled with the tire inner support 010, and also whether the shape and structural strength of the tire inner support 010 meet the standards. During the process of the lifting assembly 300 supporting the tire inner support 010 and the pressure output unit 410 coupling with it, the sensing data from the second pressure sensor reflects the accuracy of this coupling process. For example, if the positional alignment is not established, the timing and magnitude of the sensing data from the second pressure sensor may be incorrect. When the lifting assembly 300 has separated from the tire inner support 010, and the tire inner support 010 is held by the pressure output unit 410 and the pressure testing unit 420, the sensing data from the first pressure sensor 424 and the second pressure sensor simultaneously evaluate whether the shape and structural strength of the tire inner support 010 meet the standards. The second pressure sensor can be multiple independent pressure sensors or a single sheet-like pressure sensor, specifically designed to monitor pressure over a wide range.

[0039] Reference Figures 5 to 6 In one embodiment, the detection device further includes a rear conveying component 500 arranged in the same direction as the active conveying component 100 along its length. The rear conveying component 500 includes a rear conveying base 510, a rear conveying part 520, and a third drive 530. The rear conveying part 520 is disposed on the rear conveying base 510. The third drive 530 drives the rear conveying base 510 to reciprocate in the length direction, thereby entering and exiting between the receiving platform 200 and the pressure sensing component 422.

[0040] In this embodiment, the rear conveying component 500 is used to receive and transfer the tested tire inner support 010. When the tire inner support 010 to be tested is not in the position of the pressure sensing component 422, the rear conveying component 500 needs to avoid the space between the receiving platform 200 and the pressure sensing component 422, thereby providing a spatial basis for the transfer of the tire inner support 010 to be tested. When the tire inner support 010 to be tested enters the position of the pressure sensing component 422, the rear conveying component 500 can be moved to below the pressure sensing component 422 by the operation of the third drive 530 to prepare to receive and transfer the tested tire inner support 010. The third drive 530 can be of various forms, such as a motor or a linear drive type, depending on the specific settings that can form a linear drive for the rear conveying base 510. The rear conveying unit 520 can have its own power or achieve transfer by the weight of the tire inner support 010.

[0041] In one embodiment, the pressure sensing component 422 is detachably mounted on the test base 421, and the pressure head 413 is detachably mounted on the second drive 412.

[0042] In this embodiment, the detachable configuration of the pressure sensing component 422 and the pressure head 413 enables the matching of the inner support body 010 for different tire models.

[0043] In one embodiment, the output base 411 is connected to the test base 421.

[0044] In this embodiment, the output base 411 and the test base 421 are connected, which facilitates maintenance and improves the overall structural stability.

[0045] In one embodiment, the active delivery component 100 restricts and clamps the tire inner support 010 during operation.

[0046] In this embodiment, the possibility of abnormal positioning of the tire inner support 010 is reduced by limiting the position of the active conveying component 100. Specifically, a clamping plate is provided at each end of the upper surface of the active conveying component 100 in the width direction, thereby limiting the position of the tire inner support 010. The clamping direction of the tire inner support 010 should be the most stable direction, such as the equivalent length direction.

[0047] In one embodiment, the upper surface of the support segment 324 is provided with an annular third pressure sensing element.

[0048] In this embodiment, the third pressure sensor is sleeved on the fixed section 323 and located on the upper surface of the support section 324. The support status of the tire inner support 010 is monitored through the sensing data from the third pressure sensor. For example, if only some of the multiple third pressure sensors generate sensing data, it can be inferred that the support status of the tire inner support 010 on the lifting platform 320 is abnormal; similarly, if some of the sensing data from all the third pressure sensors shows an anomaly compared to pre-stored comparison data, it can also be inferred that the support status of the tire inner support 010 on the lifting platform 320 is abnormal.

[0049] In one particular embodiment, a robotic arm can be positioned above the receiving platform 200. When it is determined that the support state of the tire inner support 010 on the lifting platform 320 is abnormal, the robotic arm is controlled to grasp and transfer the tire inner support 010. The form of the robotic arm can be varied and is not specifically limited.

[0050] The present invention also provides a control method applied to the above-mentioned detection device for tire inner support, comprising: S1. Control the first drive 310 to drive the lifting platform 320 to the height of the sample position 423; S2. After controlling the second drive 412 to extend and clamp the tire inner support 010 with the sample position 423 through the pressure head 413, control the first drive 310 to drive the lifting platform 320 to be lower than the receiving platform 200. S3. Control the output of the second drive 412 with a preset pressurization curve; S4. Receive the first real-time sensing data sent by the first pressure sensing unit 424, and determine the performance of the tire inner support 010 based on the first real-time sensing data.

[0051] In this embodiment, in step S1, the lifting assembly 300 includes a first drive 310 with its output end at the top and a lifting platform 320 disposed at the output end of the first drive 310. During operation, the first drive 310 raises and lowers the lifting platform 320 in the vertical direction. Multiple support columns 321 are disposed on the lifting platform 320 corresponding to the working hole 210. From top to bottom, the support columns 321 are interconnected and nested, consisting of a guide section 322, a fixing section 323, and a support section 324, with gradually increasing and nested projected areas. The shape of the fixing section 323 matches the structural hole 011. The cross-section of the guide section 322 is smaller than that of the structural hole 011. Therefore, when the position of the inner tire support 010 deviates to a certain extent, during the ascent of the lifting platform 320, the guide section 322 first adapts to the inner tire support 010 under test. The guide section 322 can still correspond to the structural hole 011 of the inner tire support 010. The guide section 322 can be a tapered structure relative to the fixed section 323, or a chamfered structure of the fixed section 323, depending on whether it can guide the movement. When the lifting platform 320 continues to rise, the fixed section 323 on the support column 321 engages with the structural hole 011 of the inner tire support 010. If the inner tire support 010 does not have a large dimensional abnormality, the position of the inner tire support 010 can be accurately determined. At this time, the lifting platform 320 continues to rise, and the support section 324 contacts the inner tire support 010, thereby supporting and lifting the inner tire support 010 in an accurate posture.

[0052] In step S2, the second drive 412 is controlled to extend and clamp the tire inner support 010 with the sample position 423 through the pressure head 413. During this process, the lifting platform 320 still cooperates with the tire inner support 010. Before applying the test pressure, the first drive 310 is controlled to drive the lifting platform 320 to a position lower than the receiving platform 200, providing a foundation for the tire inner support 010 to enter the receiving platform 200.

[0053] In steps S3 and S4, considering the standard dimensions of the tire inner support 010 (when the curvature or flatness is normal), the sensor signal obtained by the first pressure sensor 424 should have a small difference from the standard pressure signal. The second drive 412 provides the set pressure, which is applied to the tire inner support 010 through the pressure head 413. At this time, the sensor data obtained by the first pressure sensor 424 can reflect the accuracy of the structural dimensions and structural strength performance of the tire inner support 010. For example, by comparing the data at each point of the first pressure sensor 424 (not just the data at the last clamping time, but also the real-time data during the clamping process) with the pre-stored detection standard data, if there is a large deviation in the values ​​at each position, it can be determined that the dimensions are abnormal, causing abnormal contact between the tire inner support 010 and the first pressure sensor 424. For example, if the second drive 412 provides the maximum pressure for a certain period of time, and the sensor data of the first pressure sensor 424 fluctuates, it can be determined that the structural strength performance of the tire inner support 010 is abnormal.

[0054] In one particular embodiment, step S1 includes: The first drive 310 is controlled to drive the lifting platform 320 to the height of the sample position 423, wherein when the fixed section 323 contacts the structural hole 011 of the tire inner support 010, the second drive 412 is controlled to perform at least one extension and retraction vibration.

[0055] In this embodiment, the first drive 310 can control the lifting platform 320 to form a vibration in the vertical direction, thereby assisting the tire inner support 010 to be accurately positioned. The telescopic vibration process performed by the second drive 412 should be carried out on the premise that the tire inner support 010 does not fall.

[0056] In one embodiment, the upper surface of the support segment 324 is provided with an annular third pressure sensing element, and the step S1 is followed by: Receive second real-time sensing data from multiple third pressure sensing units; Based on the relationship between the second real-time sensing data and the preset comparison data, it is determined whether the tire inner support 010 is properly supported.

[0057] In this embodiment, the third pressure sensor is sleeved on the fixed section 323 and located on the upper surface of the support section 324. The sensor data from the third pressure sensor monitors the support status of the tire inner support 010. For example, if only some of the third pressure sensors generate sensor data, it can be inferred that the tire inner support 010's support status on the lifting platform 320 is abnormal; similarly, if some of the sensor data from all the third pressure sensors shows an anomaly compared to pre-stored comparison data, it can also be inferred that the tire inner support 010's support status on the lifting platform 320 is abnormal. A robotic arm can be installed above the receiving platform 200. When an abnormal support status of the tire inner support 010 on the lifting platform 320 is detected, the robotic arm is controlled to grasp and transfer the tire inner support 010. The form of the robotic arm can be varied and is not specifically limited.

[0058] In one embodiment, the pressure head 413 is provided with a second pressure sensing unit corresponding to the portion of the tire inner support 010, and the step S2 is followed by: The third real-time sensing data sent by the second pressure sensing unit is received, and the clamping state of the inner tire support 010 is determined based on the third real-time sensing data.

[0059] The step S4 is followed by: The system receives third real-time sensing data sent by the second pressure sensing unit and determines the performance of the tire inner support 010 based on the third real-time sensing data.

[0060] In this embodiment, the data from the second pressure sensor can determine whether the pressure output unit 410 is correctly coupled with the tire inner support 010. During the process of the lifting assembly 300 supporting the tire inner support 010 while the pressure output unit 410 is coupling with it, the sensing data from the second pressure sensor reflects the accuracy of this coupling process. For example, if a positional alignment criterion is not established, the timing and magnitude of the second pressure sensor's data may be incorrect. Third, real-time sensing data can provide an indication of whether the shape and structural strength of the tire inner support 010 meet the standards. When the lifting assembly 300 has separated from the tire inner support 010, and the tire inner support 010 is held by the pressure output unit 410 and the pressure testing unit 420, the sensing data from the first pressure sensor 424 and the second pressure sensor simultaneously evaluate whether the shape and structural strength of the tire inner support 010 meet the standards.

[0061] In summary, this invention provides a detection device and control method for tire inner support bodies. Multiple working holes 210 on the receiving platform 200 provide a basis for the alignment of the tire inner support body 010 and the operation of the lifting platform 320. During the ascent of the lifting platform 320, the guide section 322 first adapts to the tire inner support body 010 to be tested, the fixing section 323 then forms an accurate fit with the structural hole 011 of the tire inner support body 010, and the support section 324 finally provides over-support, thus enabling the tire inner support body 010 to be accurately supported and lifted to the sample position 423. When the tire inner support body 010 is in the upper position, when the second drive 412 extends, the pressure head 413 clamps the tire inner support body 010 with the sample position 423. At this time, the sensor data obtained on the first pressure sensor 424 can reflect the accuracy of the structural dimensions and structural strength performance of the tire inner support body 010, ultimately achieving an accurate, efficient, and online measurement process.
