Description

Technical Field

[0001] The utility model relates to the technical field of tire processing and positioning, in particular to a positioning device. Background Art

[0002] Tires are annular elastic rubber products that enable vehicles to contact and travel on the road, usually mounted on metal wheels. During the production and processing of tires, it is usually necessary to use a suitable positioning device to clamp and fix the tires for subsequent operations.

[0003] Existing tire positioning devices generally use clamping blocks to directly clamp the tread of the tire. However, when the clamping blocks used for positioning clamp the tire, on the one hand, due to the small clamping area, the pressure is large, and the tire is prone to uneven force, thereby affecting the processing quality of the tire (such as wear, cracks, and bulges); on the other hand, the clamping effect of the clamping blocks is relatively poor, and the tire is prone to fall off, shift, and other phenomena during operations after positioning, which reduces processing accuracy and efficiency. Utility Model Content

[0004] The utility model aims to solve the technical problem that the existing tire positioning device easily causes excessive force on the tire and poor clamping effect. The utility model provides a positioning device that can ensure the quality of the tire during the tire processing and positioning process and effectively improve the positioning effect.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a positioning device, comprising:

[0006] A base, used for supporting a tire, wherein a sidewall of one side of the tire contacts the base;

[0007] A first positioning assembly includes two first clamps, wherein the first clamps are connected to the base in a manner that they can move along a first direction;

[0008] A second positioning assembly includes two second clamps, wherein the second clamps are connected to the base in a manner that they can move along a second direction; the two first clamps and the two second clamps are used to abut against the inner surface of the tire along the first direction and the second direction respectively, and the abutting surfaces of the first clamps and the second clamps are adapted to the inner surface of the tire;

[0009] A plurality of third positioning assemblies connected to the first fixture and / or the second fixture, each of the third positioning assemblies comprising a pressing plate, the pressing plate being used to move relative to the base to switch between a first state and a second state;

[0010] In the first state, the pressure plate abuts against the sidewall of the other side of the tire to limit the movement of the tire relative to the base;

[0011] In the second state, the pressure plate and the sidewall of the other side of the tire are staggered along a third direction; the third direction is perpendicular to the first direction and the second direction respectively.

[0012] By adopting the above technical solution, the first clamp of the first positioning assembly and the second clamp of the second positioning assembly can be clamped together on the inner surface of the tire (i.e., the inner surface of the tire for setting the rim portion) along the first direction and the second direction respectively, so as to achieve a multi-directional clamping effect, and have a better clamping and positioning effect. Moreover, the abutting surfaces of the first clamp and the second clamp can be adapted to the inner surface of the tire, so that the tire will not be subjected to a large pressure due to a small clamp area, or the tire will not be subjected to uneven force. Such adverse effects such as wear, damage, displacement, etc. will be avoided, which provides safety and quality assurance for the subsequent processing of the tire after it is positioned.

[0013] When using the positioning device, the pressure plate of the third positioning component can move relative to the base so that the pressure plate is first in the second state (so that the pressure plate and the sidewall of the tire are offset relative to the third direction, and the pressure plate is separated from the sidewall of the tire). On this basis, the tire can be placed on the base, and along the third direction, the sidewall of one side of the tire faces upward; then the first clamp of the first positioning component abuts against the inner surface of the tire along the first direction, and the second clamp of the second positioning component abuts against the inner surface of the tire along the second direction, thereby providing all-round support, clamping and fixing along the circumference of the tire.

[0014] At the same time, the pressure plate of the third positioning assembly can also move relative to the base to switch from the second state to the first state; when in the first state, the pressure plate can abut against the side surface of the tire, and then cooperate with the first and second positioning assemblies to jointly clamp the inner surface of the tire, which can effectively improve the clamping and positioning effect of the positioning device, effectively improve the stability of the tire in the positioning device, thereby also improving the processing accuracy to effectively improve the overall quality of the tire.

[0015] It should be noted that when there is no need to position the sidewall of the tire (i.e., when it is necessary to switch from the first state to the second state), the pressure plate can move in a certain direction relative to the base (e.g., move in the third direction described later and rotate in the fourth direction, or rotate in the fourth direction described later) so that the pressure plate switches to the above-mentioned second state. In this case, when the first and second positioning components are not in contact with the inner surface of the tire, the tire can be removed from the base, and when the first and second positioning components are still in contact with the inner surface of the tire, the tire is still in a state of being positioned by the positioning device, but the third positioning component no longer restricts the sidewall of the tire, that is, the pressure plate and the tire are staggered.

[0041] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] See also Figure 1 and Figure 2 The embodiment of the present application provides a positioning device 1 for clamping and positioning a tire 10. Figure 1 The schematic diagram of the structure of the positioning device 1 with the tire 10 is shown as an example. Figure 2 The exploded view of the positioning device 1 according to the embodiment of the present application is shown as an example, and for the convenience of demonstration, Figure 2 The tire 10 is hidden.

[0043] The positioning device 1 of the embodiment of the present application comprises a base 2, a first positioning component 3, a second positioning component 4 and four third positioning components 5. Figure 1 and Figure 2 Four third positioning components 5 are exemplarily shown in the figure, but the embodiment of the present application does not limit the number of the third positioning components 5. For example, three, five, six, etc. can also be set.

[0044] See also Figure 1 It can be seen that the sidewall of the tire 10 is supported on the working surface of the base 2 (i.e. Figure 1 The positioning device 1 can be moved in a first direction (such as Figure 1 The X direction shown in FIG. 1 and the second direction (as shown in FIG. Figure 1 The inner surface of the tire 10 (i.e., the inner surface of the tire 10 for fitting the rim, i.e., the side opposite to the tread) is jointly extruded by the two wheels.

[0045] See also Figure 1 and Figure 2 The above-mentioned extrusion process of the tire 10 along the first direction and the second direction is achieved by the cooperation of the first positioning component 3 and the second positioning component 4.

[0046] The first positioning assembly 3 includes two first clamps 31. It can be seen that one of the first clamps 31 is located on the left side in the first direction (i.e. Figure 1 and Figure 2 The other first fixture 31 is located on the right side in the first direction (i.e. Figure 1 and Figure 2 The two first clamps 31 are connected to the base 2 in a manner that they can move along the first direction. That is, each first clamp 31 can move leftward (eg, Figure 1 and Figure 2 X1 direction shown in the figure) and rightward (as shown in the figure Figure 1 and Figure 2 Movement in the X2 direction shown in FIG.

[0047] The second positioning assembly 4 includes two second clamps 41. It can be seen that one of the second clamps 41 is located at the front side in the second direction (i.e. Figure 1 and Figure 2 The other second fixture 41 is located at the rear side in the second direction (ie Figure 1 and Figure 2 The two second clamps 41 are connected to the base 2 in a manner that they can move along the second direction. That is, each second clamp 41 can move forward along the second direction relative to the base 2 (eg, Figure 1 and Figure 2 Y1 direction shown in the figure) and backward (as shown in the figure Figure 1 and Figure 2 Movement in the Y2 direction shown in FIG.

[0048] Based on this, the two first clamps 31 can move away from each other along the first direction to respectively abut against the inner surface of the tire 10, and at the same time, the two second clamps 41 can move away from each other along the second direction to respectively abut against the inner surface of the tire 10. In addition, the abutting surface of each first clamp 31 and each second clamp 41 is adapted to the inner surface of the tire 10, that is, each first clamp 31 and each second clamp 41 has an arc surface adapted to the inner surface of the tire 10, so that when the inner surface of the tire 10 is squeezed, the clamping effect can be effectively improved.

[0049] Continue reading Figure 1 and Figure 2 The positioning device 1 of the embodiment of the present application can further restrict the sidewall of the tire through the above-mentioned four third positioning components 5 to further improve the fixing effect of the tire 10.

[0050] It can be seen that each of the first clamps 31 is connected to a third positioning component 5, and each of the second clamps 41 is connected to a third positioning component 5. However, the embodiment of the present application does not limit this, that is, the third positioning component 5 can be only provided on the two first clamps 31 according to the actual application, or only provided on the two second clamps 41, or the third positioning component 5 is only provided on one of the first clamps 31, or the third positioning component 5 is only provided on one of the second clamps 41.

[0051] Continue reading Figure 1 and Figure 2 Each third positioning assembly 5 includes a pressing plate 51, and the pressing plate 51 is used to move relative to the base 2 to switch between the first state and the second state. Figure 1 The structural diagram in the first state is exemplarily shown.

[0052] It can be seen that in the first state, the pressure plate 51 abuts against the sidewall of the tire 10 that is away from the base 2 (i.e. Figure 1 In the second state, the pressure plate 51 and the sidewall of the tire 10 are aligned along the third direction (as indicated by the Z1 direction in the figure), thereby limiting the movement of the tire 10 relative to the base 2 (i.e., the tire 10 cannot be separated from the base 2). Figure 1 The pressure plate 51 is offset from the sidewall of the tire 10 (in the Z direction shown in FIG).

[0053] In a possible implementation, the pressing plate 51 can be arranged along a third direction (eg Figure 1 The Z direction shown in FIG. 1 ) moves, and moves along a fourth direction (such as Figure 1 The device can be rotated in the W direction shown in FIG. 1 , thereby being able to switch between the above-mentioned first state and the above-mentioned second state.

[0054] In another possible implementation, the pressing plate 51 may be directly arranged along the fourth direction (eg Figure 1 W direction shown in the figure) rotates, thereby switching between the above-mentioned first state and the above-mentioned second state.

[0055] It should be noted that the third party (such as Figure 1 and Figure 2 The Z direction shown in FIG. 1 is respectively related to the first direction (as shown in FIG. Figure 1 and Figure 2 The X direction shown in FIG. 1 ), the second direction (such as Figure 1 and Figure 2 The fourth direction (as shown in the Y direction) is perpendicular to the Figure 1 W direction shown in ) is arranged around a third direction.

[0056] See also Figure 3 Combined with Figure 1 and Figure 2 In a possible implementation manner, the base 2 is provided with a first slot 21, and the first slot 21 is arranged along a first direction (such as Figure 3 The X direction shown in FIG. 1 extends.

[0057] See also Figure 1 Combined with Figure 3 The first positioning assembly 3 also includes a first driving unit 32, and the first driving unit 32 includes a first part and a second part. It can be seen that the first part is accommodated in the first slot body 21 (such as the first bidirectional screw rod and the first transmission block described later), and the second part (such as the first motor described later) is located outside the first slot body 21.

[0058] In addition, the first clamps 31 are arranged at intervals at the top of the first tank body 21 along the third direction (i.e. Figure 1In other words, illustratively, the first fixture 31 does not contact the working surface of the base 2, so that the first fixture 31 can move left and right relative to the base 2. In addition, the first fixture 31 is connected to the first driving part 32 in a movable manner along the first direction.

[0059] See also Figure 4 Combined with Figure 1 In a possible implementation, the two first clamps 31 are respectively located on both sides of the first driving part 32, and the first driving part 32 is used to drive the two first clamps 31 to move in opposite directions along the first direction, that is, the first driving part 32 can drive the first clamp 31 on the left side to move leftward along the first direction (such as Figure 4 The first driving unit 32 can drive the first clamp 31 on the right side to move rightward along the first direction (as shown in the X1 direction). Figure 4 Therefore, the two first clamps 31 can be brought into contact with the inner surface of the tire 10 (such as Figure 1 shown).

[0060] Alternatively, the first driving unit 32 can drive the two first clamps 31 to move toward each other along the first direction, that is, the first driving unit 32 can drive the first clamp 31 on the left to move rightward along the first direction (such as Figure 4 The first driving unit 32 can drive the first clamp 31 on the right side to move to the left along the first direction (as shown in the X2 direction). Figure 4 The two first clamps 31 move together away from the inner surface of the tire 10 (in the X1 direction shown in FIG. 1 ).

[0061] See also Figure 4 Combined with Figures 1 to 3 In a possible implementation, the first driving unit 32 includes a first motor 321 (ie, the second part mentioned above), a first bidirectional screw rod 322, and two first transmission blocks 323 (ie, the first part mentioned above).

[0062] It can be seen that the first bidirectional screw rod 322 is arranged along the first direction (such as Figure 4 The first motor 321 is located outside the first tank 21 and connected to the first bidirectional screw rod 322. The two first transmission blocks 323 are respectively located on both sides of the first bidirectional screw rod 322, and each first transmission block 323 is sleeved on the first bidirectional screw rod 322. At the same time, each first transmission block 323 is connected to the first clamp 31.

[0063] The first motor 321 can drive the first bidirectional screw rod 322 to move in a fifth direction (such as Figure 4Alternatively, the first motor 321 can drive the first bidirectional screw rod 322 to rotate in the sixth direction (as shown in the a direction) to drive the two first transmission blocks 323 to slide oppositely along the first slot 21 (i.e., along the first direction). Figure 4 b direction) to drive the two first transmission blocks 323 to slide toward each other along the first slot body 21. It can be understood that the first slot body 21 can further provide a better guiding effect for the first positioning assembly 3 of the embodiment of the present application.

[0064] It should be noted that the embodiment of the present application does not limit the fifth direction and the sixth direction. As long as the first motor 321 can drive the two first transmission blocks 323 to move in opposite directions and towards each other along the first direction, they are within the protection scope of the embodiment of the present application.

[0065] See also Figure 4 Combined with Figure 1 and Figure 2 In a possible implementation, each first clamp 31 includes a first arc-shaped positioning plate 311, and the first arc-shaped positioning plate 311 includes an outer arc surface 3111, and the outer arc surface 3111 of the first arc-shaped positioning plate 311 is the abutting surface of the first clamp 31, that is, the outer arc surface 3111 of the first arc-shaped positioning plate 311 is used to abut against the inner surface of the tire 10, and according to the foregoing, the outer arc surface 3111 of the first arc-shaped positioning plate 311 is adapted to the curvature of the inner surface of the tire 10. Further, it can be seen that the first arc-shaped positioning plate 311 is used to connect with the corresponding first transmission block 323.

[0066] See also Figure 4 and Figure 6 In a possible implementation, each first fixture 31 further includes a first arc-shaped clamping block 312, and the first arc-shaped clamping block 312 is connected to the corresponding first transmission block 323. Combined with the above description, the first transmission block 323 can be driven along the first direction (such as Figure 4 and Figure 6 Therefore, the first arc-shaped clamping block 312 can move away from and towards each other along the first direction through the corresponding first transmission block 323.

[0067] Continue reading Figure 4 and Figure 6 The first arc-shaped positioning plate 311 also includes an inner arc surface 3112 , and the first arc-shaped clamping block 312 is connected to the inner arc surface 3112 of the first arc-shaped positioning plate 311 .

[0068] It can also be seen that along the third direction (such as Figure 4The height of the first arc-shaped positioning plate 311 is greater than the height of the first arc-shaped clamping block 312. Therefore, the first arc-shaped clamping block 312 and the inner arc surface 3112 of the first arc-shaped positioning plate 311 can form a Figure 4 The first placement space 30 shown is further combined with Figure 1 The first placement space 30 is used to place the third positioning component 5 (exemplarily, a bracket described later for placing the third positioning component 5).

[0069] See also Figure 3 Combined with Figure 1 and Figure 2 In a possible implementation manner, the base 2 is further provided with a second slot 22, and the second slot 22 is arranged along a second direction (such as Figure 3 Extends in the Y direction shown in FIG.

[0070] See also Figure 1 Combined with Figure 3 The second positioning assembly 4 also includes a second driving portion 42, and the second driving portion 42 includes a third portion and a fourth portion connected to each other. It can be seen that the first portion is accommodated in the second slot body 22 (for example, the second bidirectional screw rod and the second transmission block described later). In addition, the second clamp 41 is arranged at intervals at the top of the second slot body 22 along the third direction (i.e. Figure 1 In other words, illustratively, the second fixture 41 does not contact the working surface of the base 2, so that the second fixture 41 can move forward and backward relative to the base 2. In addition, the second fixture 41 is connected to the second driving part 42 in a movable manner along the second direction.

[0071] See also Figure 5 Combined with Figure 1 In a possible implementation, the two second clamps 41 are respectively located on both sides of the second driving part 42, and the second driving part 42 is used to drive the two second clamps 41 to move in opposite directions along the second direction. That is, the second driving part 42 can drive the second clamp 41 on the front side (i.e. Figure 5 The second fixture 41 indicated by the Y1 direction in the figure) moves forward in the second direction (eg Figure 1 and Figure 5 The second driving unit 42 can drive the second clamp 41 on the rear side to move backward along the second direction (as shown in the Y1 direction). Figure 1 and Figure 5 Therefore, the two second clamps 41 can be brought into contact with the inner surface of the tire 10 (such as Figure 1 shown).

[0072] Alternatively, the second driving part 42 can drive the two second clamps 41 to move toward each other along the second direction, that is, the second driving part 42 can drive the front second clamp 41 to move backward along the second direction (such as Figure 5 The second driving part 42 can drive the second clamp 41 at the rear side to move forward along the second direction (as shown in the Y2 direction). Figure 4 The two second clamps 41 move together away from the inner surface of the tire 10 (in the Y1 direction shown in FIG. 1 ).

[0073] See also Figure 5 In a possible implementation manner, the third part of the second driving part 42 includes a second bidirectional screw rod 422 and two second transmission blocks 423 , and the fourth part of the second driving part 42 includes a second motor 421 .

[0074] It can be seen that the second bidirectional screw 422 extends along the second direction and is accommodated in the second slot body 22, and the second motor 421 is located outside the second slot body 22 and connected to the second bidirectional screw 422. Two second transmission blocks 423 are respectively located on both sides of the second bidirectional screw 422, and each second transmission block 423 is sleeved on the second bidirectional screw 422, and each second transmission block 423 is connected to the second clamp 41.

[0075] The second motor 421 can drive the second bidirectional screw rod 422 to move in a fifth direction (eg Figure 5 Alternatively, the second motor 421 can drive the second bidirectional screw rod 422 to rotate in the sixth direction (as shown in the a direction) to drive the two second transmission blocks 423 to slide oppositely along the second slot 22 (i.e., along the second direction). Figure 5 b direction) to drive the two second transmission blocks 423 to slide toward each other along the second slot body 22. It can be understood that the second slot body 22 can also further provide a better guiding effect for the second positioning assembly 4 of the embodiment of the present application.

[0076] See also Figure 5 Combined with Figure 1 and Figure 2 In a possible implementation, each second clamp 41 includes a second arc-shaped positioning plate 411 , and the second arc-shaped positioning plate 411 includes an outer arc surface 4111 , and the outer arc surface of the second arc-shaped positioning plate 411 is the abutment surface of the second clamp 41 .

[0077] That is, the outer arc surface 4111 of the second arc-shaped positioning plate 411 is used to abut against the inner surface of the tire 10, and according to the foregoing, the outer arc surface 4111 of the second arc-shaped positioning plate 411 is adapted to the curvature of the inner surface of the tire 10. Further, it can be seen that the second arc-shaped positioning plate 411 is used to connect with the corresponding second transmission block 423.

[0078] See also Figure 5 and Figure 6 In a possible implementation, each second clamp 41 further includes a second arc-shaped clamping block 412, and the second arc-shaped clamping block 412 is connected to a corresponding second transmission block 423. Combined with the above description, the second transmission block 423 can be driven along the second direction (such as Figure 5 and Figure 6 Therefore, the second arc-shaped clamping block 412 can move away from and towards each other along the second direction through the corresponding second transmission block 423.

[0079] Continue reading Figure 5 and Figure 6 The second arc-shaped positioning plate 411 also includes an inner arc surface 4112 , and the second arc-shaped clamping block 412 is connected to the inner arc surface 4112 of the second arc-shaped positioning plate 411 .

[0080] It can be seen that along the third direction (such as Figure 5 The height of the second arc-shaped positioning plate 411 is greater than the height of the second arc-shaped clamping block 412. Therefore, the second arc-shaped clamping block 412 and the inner arc surface of the second arc-shaped positioning plate 411 can form a Figure 5 The second placement space 40 shown is further combined with Figure 1 The second placement space 40 is used to place the third positioning component 5 (exemplarily, a bracket described later for placing the third positioning component 5).

[0081] See also Figure 1 For example, the first bidirectional screw rod 322 is placed in the first slot body 21, and the second bidirectional screw rod 422 is placed in the second slot body 22. Figure 1 It can be seen intuitively that along the third direction (such as Figure 1 In the Z direction shown in the figure, the first bidirectional screw rod 322 in the first slot body 21 is located on the top of the second bidirectional screw rod 422 in the second slot body 22, that is, the first bidirectional screw rod 322 in the first slot body 21 and the second bidirectional screw rod 422 in the second slot body 22 are alternately arranged up and down along the third direction.

[0082] Further reading Figure 2 and Figure 3 ,exist Figure 2 and Figure 3 In the embodiment, the inner wall of the first groove body 21 can be seen directly, but the inner wall of the second groove body 22 cannot be seen. Figure 2 and Figure 3 The depth of the first slot body 21 is shown as an example to be less than the depth of the second slot body 22, but the embodiment of the present application is not limited thereto. For example, along the third direction (such as Figure 1, Figure 2 , Figure 3 The depth of the first slot body 21 may also be greater than the depth of the second slot body 22. As long as the first bidirectional screw rod 322 and the second bidirectional screw rod 422 can respectively perform the above-mentioned movements in the first slot body 21 and the second slot body 22, they all fall within the protection scope of the embodiments of the present application.

[0083] See also Figure 7 Combined with Figure 1 and Figure 2 In a possible implementation manner, the third positioning component 5 also includes an elastic component 52 and a bracket 53 .

[0084] Exemplarily, the bracket 53 is a rectangular frame structure. As can be seen from the foregoing, the third positioning component 5 is used to be placed in the first placement space 30 of the first fixture 31 (such as Figure 4 As shown in FIG. 1 , that is, the bracket 53 can be placed in the first placement space 30 to be connected to the first fixture 31. Accordingly, according to the foregoing, the third positioning assembly 5 is used to be placed in the second placement space 40 of the second fixture 41 (as shown in FIG. 1 ). Figure 5 As shown), that is, the bracket 53 can be placed in the second placement space 40 to be connected to the second clamp 41. The embodiment of the present application does not limit the shape and number of the bracket 53, as long as it can be stably connected to the first clamp 31 and the second clamp 41, it belongs to the protection scope of the embodiment of the present application.

[0085] Continue reading Figure 7 Combined with Figure 1 and Figure 2 The elastic component 52 is disposed inside the bracket 53, and the top end of the elastic component 52 (i.e. Figure 7 The end indicated by the Z1 direction in the middle) is elastically connected to the bracket 53, and the pressing plate 51 is located outside the bracket 53, and the pressing plate 51 is arranged along the third direction (such as Figure 7 The Z direction shown in FIG. 1 is movable in a manner that is compatible with the bottom end (i.e. Figure 7 That is, along the third direction, the pressing plate 51 is elastically connected to the bracket 53 through the elastic component 52.

[0086] In a possible implementation described above, the pressing plate 51 can move along the third direction and rotate along the fourth direction to switch between the first state and the second state. That is, in this case, for example, the pressing plate 51 can move upward along the third direction (such as Figure 7 The elastic component 52 moves upward along the third direction. At the same time, the pressing plate 51 moves along the fourth direction (such as Z1 direction shown in FIG. 5 ) through the elastic component 52 and the bracket 53. Figure 7The pressure plate 51 is rotatably connected in the W direction shown in the figure, that is, the pressure plate 51 can be rotated in a fourth direction so that the pressure plate 51 and the sidewall of the tire 10 are staggered along the third direction, that is, the pressure plate 51 is away from the sidewall of the tire 10 (that is, the above-mentioned second state).

[0087] Then, the elastic component 52 can drive the pressing plate 51 downward along the third direction (such as Figure 7 The pressure plate 51 moves in the Z2 direction shown in the figure to press the sidewall of the tire 10 downward (ie, the first state described above).

[0088] That is to say, in actual application, the pressing plate 51 can be pulled up to drive the elastic component 52 connected to the pressing plate 51 to move upward along the third direction, and the pressing plate 51 can be turned to one side of the tire 10 along the fourth direction through the elastic component 52. At this time, the pressing plate 51 is released, and the pressing plate 51 can press the tire 10 downward under the elastic force of the elastic component 52 downward along the third direction. When the positioning of the third positioning component 5 is not needed, the pressing plate 51 can be pulled up, and the pressing plate 51 can be turned to any other position away from the tire 10 along the fourth direction through the elastic component 52, so as to switch to the non-pressing state (i.e., the second state).

[0089] In another possible embodiment described above, the pressing plate 51 can be directly rotated in the fourth direction to switch between the first state and the second state. In this case, although the pressing plate 51 is pressed against the sidewall of the tire (the first state), the pressing plate 51 can still be rotated forward or backward in the fourth direction to move the pressing plate 51 away from the sidewall of the tire 10.

[0090] See also Figure 7 Combined with Figure 1 and Figure 2 In a possible implementation manner, it can be seen that the interior of the bracket 53 includes a receiving chamber 530 ; the elastic component 52 includes a sliding column 521 , a sliding plate 522 , and a spring 523 .

[0091] It can be seen that the sliding column 521 moves along the third direction (such as Figure 7 The sliding post 521 extends in the Z direction shown in FIG. 5 , and a portion of the sliding post 521 is accommodated in the accommodating cavity 530. The top end of the sliding post 521 (i.e. Figure 7 The Z1 direction) passes through and extends out of the bracket 53, and the extended part is connected to the above-mentioned pressing plate 51.

[0092] Furthermore, the sliding plate 522 is a rectangular plate-shaped structure and is accommodated in the above-mentioned accommodation cavity 530. Figure 7 In the state shown in FIG. 1 , the sliding plate 522 and the inner bottom wall of the bracket 53 (i.e., the bottom wall of the accommodating cavity 530, as shown in FIG. 1 ) are aligned with each other. Figure 7Furthermore, the bottom end of the sliding column 521 (i.e. Figure 7 The Z2 direction is rotatably connected to the sliding plate 522.

[0093] The spring 523 is fixed to the sliding plate 522 and the top wall of the accommodating cavity 530 (such as Figure 7 That is, the top end of the spring 523 is connected to the top cavity wall of the accommodating cavity 530, and the bottom end of the spring 523 is connected to the sliding plate 522.

[0094] Based on this, combined with the above description, illustratively, when the pressing plate 51 is lifted, the sliding column 521 connected to the pressing plate 51 can drive the sliding plate 522 upward along the third direction (such as Figure 7 When the pressing plate 51 is released, the spring 523 can drive the sliding plate 522 downward along the third direction (such as Z1 direction shown in FIG. Figure 7 The Z2 direction shown in FIG. 1 moves to drive the pressing plate 51 to move downward to squeeze the Figure 1 When the tire 10 does not need to be positioned in the third direction, the pressing plate 51 can be lifted along the third direction, and at the same time, the pressing plate 51 can continue to be rotated along the fourth direction under the action of the sliding column 521, or the pressing plate 51 can be directly rotated along the fourth direction to keep the pressing plate 51 away from the sidewall of the tire 10.

[0095] See also Figure 7 In a possible implementation, the third positioning assembly 5 further includes a guide post 54, which extends along the third direction and is disposed in the above-mentioned accommodation cavity 530. Figure 7 Two guide posts 54 are exemplarily shown in the figure, but the embodiment of the present application does not limit the number of guide posts 54.

[0096] The sliding plate 522 is used to be slidably mounted on the outer periphery of the guide column 54 along the third direction. Therefore, when the sliding plate 522 performs the upward and downward movements along the third direction, the guide column 54 can provide a guiding function for the sliding plate 522 .
