Description

Technical Field

[0001] This utility model belongs to the field of tires, specifically relating to a non-pneumatic tire tread component assembly and disassembly testing device. Background Technology

[0002] Currently, some non-pneumatic tire designs consist of a rim and multiple tread components covering it. With this type of tire structure, if the tread is damaged by impact, it is not necessary to replace the entire tire tread; only the tread component corresponding to the damaged rubber needs to be replaced. This saves manufacturing costs while ensuring the performance and safety of the non-pneumatic tire.

[0003] The tread component consists of a rubber tread, a tread base plate, and side plates. Currently, the external appearance of the tread component is typically assessed for product quality through visual inspection and hardness testing. Then, specialized equipment, such as X-ray inspection equipment, is used to inspect the internal components. Once the entire tread component passes inspection, it is transported to the installation area to await installation.

[0004] The aforementioned process setup is relatively complex, which greatly restricts the efficiency of testing and installation. Utility Model Content

[0041] In this utility model, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this utility model. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this utility model may be combined with other embodiments without conflict.

[0042] A non-pneumatic tire tread component assembly and disassembly testing device, comprising:

[0043] Gantry frame;

[0044] The sliding seat 2 is slidably installed along the upper crossbeam of the gantry frame;

[0045] The drive shaft 7 is rotatably connected at both ends to the side supports of the gantry frame and is located below the crossbeam;

[0046] The gripper 1 is located on one side of the sliding seat 2, and is moved vertically by a vertical lifting device.

[0047] The hammer 3 and the accelerometer 4 are respectively installed on the other side of the crossbeam sliding seat 2 via the hammer drive telescopic mechanism 5 and the accelerometer drive telescopic mechanism 6. The hammer 3 is driven by the hammer drive telescopic mechanism 5 to move and apply an impact force to the tread component to be tested. During the above process, the accelerometer 4 is kept in contact with the tread component to be tested by driving the movement of the accelerometer drive telescopic mechanism 6.

[0048] Force sensor 18 is disposed at the striking end face of the force hammer 3.

[0049] The rim structure is mounted on the drive shaft 7, and by rotating the drive shaft 7, the gripper 1, the hammer 3 and the acceleration sensor 4 can be aligned with the corresponding tread component to be installed or tested and the position where it needs to be installed or tested.

[0050] First, after the drive shaft 7 rotates to the designated position, the gripper 1 places the corresponding tread component onto the designated position on the surface of the non-pneumatic tire rim via the sliding seat 2 and the vertical lifting device. Then, by controlling the position of the sliding seat 2 and the vertical lifting device, the hammer 3 and the acceleration sensor 4 are positioned directly opposite the tread component. The hammer drives the telescopic mechanism 5 to apply a striking force, while the acceleration sensor drives the telescopic mechanism 6 to ensure that the acceleration sensor 4 remains in contact with the tread component during the striking process. After the test is completed, tread components that meet the test requirements can be directly installed in their corresponding positions.

[0051] Testing process: The force hammer 3 applies vibration to the tread component, and the vibration signal is collected by the force sensor 18 and the acceleration sensor 4. The collected signal is transmitted to the data acquisition unit for processing to obtain the modal vibration mode of the tread component after installation. The modal vibration mode characteristic parameters of the tread component without defects are compared with those of the standard tread component. That is, by comparing the current modal vibration mode with the standard vibration mode, the presence of defects inside the tread component can be identified.

[0052] Detection principle: Defects in the tread components can cause changes in structural signals, affecting the modal vibration modes of the tread components. By observing the modal vibration modes, key information such as the location and severity of internal defects can be obtained, providing a reference for subsequent production process improvements.

[0053] In some embodiments, the gripper includes:

[0054] The first clamping seat 12 and the second clamping seat 13 are arranged in a staggered structure along their clamping movement direction;

[0055] Clamping plates 15 are respectively disposed on the first clamping seat 12 and the second clamping seat 13.

[0056] Specifically, the staggered structure is adopted mainly to address the fact that the tread component itself is installed on an inclined surface. Since the tread component can be installed on an inclined surface to improve its installation stability, the first clamping seat 12 and the second clamping seat 13 are also appropriately designed with staggered positioning to ensure the stable clamping effect.

[0057] In some embodiments, a clamping plate telescopic drive device 14 for moving the clamping plate 15 in the vertical direction is provided between the clamping plate 15 and both the first clamping seat 12 and the second clamping seat 13. In this embodiment, by providing the clamping plate telescopic drive device 14, the clamping plate 15 can be adjusted in the vertical direction, and the clamping sensitivity can be improved in conjunction with the vertical lifting device.

[0058] Furthermore, based on this scheme, the cross-section of the clamping plate 15 is designed as an L-shaped structure, and the opposing surfaces of the clamping plate 15 and its corresponding first clamping seat 12 and second clamping seat 13 are both arc-shaped structures.

[0059] Specifically, such as Figure 3 As shown, the upper end face of the L-shaped structure of the clamping plate 15 and the lower end face of the first clamping seat 12 form a structure for clamping the upper and lower end faces of the tread component. The structure is set as an arc shape to make it more adaptable. The method of simply applying lateral clamping force, that is, the two clamping plates 15 clamping the tread component laterally, is replaced by using the clamping plate telescopic drive device 14 to adjust and adapt to tread components of different thicknesses. The hooking method of the L-shaped structure reduces the locking force that needs to be applied laterally, thereby reducing the risk of extrusion deformation of the tread component.

[0060] In some embodiments, a clamping mechanism telescopic drive device 16 for driving the clamping movement of the first clamping seat 12 and the second clamping seat 13 is provided between them. The above arrangement achieves a compact device structure layout.

[0061] In some embodiments, it also includes:

[0062] Auxiliary suction cups 17 are respectively disposed on the first clamping seat 12 and the second clamping seat 13, and are located inside the clamping plate 15. The auxiliary suction cups 17 can further improve stability.

[0063] In some embodiments, the drive shaft 7 includes:

[0064] Connecting shaft 8, one end of which is rotatably connected to one side of the gantry frame;

[0065] The retractable shaft 10 is connected to the other end of the connecting shaft 8. The other end of the shaft is connected to the telescopic structure to realize the installation space for the non-pneumatic tire rim in the retracted state and the rotational connection with the other side of the gantry in the extended state.

[0066] Since the process of the above embodiments inevitably involves the technical step of installing the wheel rim on the drive shaft 7, in order to improve the convenience of installation, the connecting retractable shaft 10 adopts a retractable structure. During the installation process, it first retracts to provide the wheel rim with the corresponding installation space, and after installation, it extends to form a rotating connection state to ensure the normal use of the equipment.

[0067] In some embodiments, it also includes:

[0068] The mounting sleeve 9 is fitted onto the connecting shaft 8, and a connecting disc 11 is mounted on it. A fixed connection is achieved between the connecting disc 11 and the corresponding wheel rim.

[0069] In some embodiments, it also includes:

[0070] A crossbeam seat is horizontally mounted on the crossbeam;

[0071] A vertical lifting device is provided between the crossbeam seat and the sliding seat 2 to drive the sliding seat 2 to move in the vertical direction.

[0072] In some embodiments, it also includes:

[0073] The vision inspection drive and control unit is used to monitor the position of the tread component to be inspected and drive the drive shaft 7 to rotate so that the gripper 1, the force hammer 3 and the acceleration sensor 4 are in the corresponding working position.

[0074] Its working principle is as follows:

[0075] First, a corresponding bracket is installed below one side of the connecting retraction shaft 10 for support to prevent deformation of one end of the connecting shaft 8 due to unbalanced force. The connecting retraction shaft 10 retracts, and the rim to be installed is clamped and lifted using the gripper 1. Then, the rim is installed on the mounting sleeve shaft 9 by adjusting its position, and finally, a fixed connection is completed via the connecting plate 11. In the above process, after the rim is installed on the mounting sleeve shaft 9, the connecting retraction shaft 10 extends to achieve an overall rotational connection of the drive shaft 7.

[0076] Tread component inspection and installation: The tread component is gripped and moved to the designated position by the gripper 1. The drive shaft 7 rotates accordingly to complete the pre-installation and placement of the tread component. After pre-installation and placement, the sliding seat 2 moves, and the corresponding positions of the force hammer 3 and acceleration sensor 4 are adjusted for inspection. The current inspection data is compared with pre-stored standard data to determine whether it meets the corresponding requirements. If it meets the requirements, the tread component is directly connected and fixed to the rim. If it does not meet the requirements, the tread component is replaced. The above steps are performed sequentially until the entire non-pneumatic tire inspection and installation operation is completed.

[0077] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
