A plurality of positioning seats 18 are fixedly installed on a horizontal surface and a vertical surface of the carrier frame 13. The positioning seat 18 is connected with a ball 17 in clearance fit. Only through the third motor 37, the two carrier frames 13 and the two limiting side bars 11 can be driven, so that a tire can be positioned in front, rear, left, right, upper and lower directions, the function of synchronous positioning is ensured, and the positioning effect is good. Meanwhile, rolling friction contact is adopted at multiple positions, so that when the tire is driven to rotate, rolling friction can be carried out, the friction resistance is low, the wear is small, and damage is avoided. At the same time, a positioning structure is integrally integrated in the shell and two sides of the shell, and is small in occupied space. The tire is inserted from the bottoms of the two carrier frames 13, so that the top of the tire is in contact with the disc 26. The control cabinet 15 controls the third motor 37. The third motor 37 drives the second circular shaft 31 to rotate, so that the second cylindrical gear 32 rotates. The second cylindrical gear 32 drives the two first cylindrical gears 30 to rotate in opposite directions. The first cylindrical gear 30 is in engaged transmission with the tooth space 20, so that the carrier frame 13 is driven to move. Because the rotating directions of the two first cylindrical gears 30 are opposite, the two carrier frames 13 move in opposite directions. During the moving process, the two carrier frames 13 approach each other under the guidance of the guide rod 21 and the guide hole, so that the top of the tire is positioned and suspended. Atop outer ring of the tire is in contact with the bottom of the disc 26. A back surface and a front surface of the top of the tire are in contact with the ball 17 on the vertical surface of the carrier frame 13 to realize positioning at front and rear positions.

At the same time, when the second cylindrical gear 32 rotates, the third cylindrical gear 33 is driven to rotate. The two screw rods 38 are driven to rotate. The two screw rods 38 are opposite in threaded rotating directions. At the same time, the screw hole 39 is matched with the screw rod 38. The two screw rods 38 provide driving for the limiting side bars 11 when rotating. The limiting side bars 11 are guided by the guide groove 34 to move left and right. Because the two screw rods 38 are opposite in threaded rotating directions, the two limiting side bars 11 move in opposite directions. The two limiting side bars 11 approach each other, and the rollers 14 are in contact with two sides of the tire, so that a tire body is positioned at left and right positions.

[0037] As shown in FIG. 3 and FIG. 6, as a specific scheme, a positioning frame 23 is arranged between the two carrier frames 13. The positioning frame 23 is located at the bottom of the shell 10. Slots are formed in two ends of the positioning frame 23. The slot is connected with the guide bar 22 in clearance fit. A tail end of the guide bar 22 is fixedly connected with a vertical frame surface of the carrier frame 13. A plurality of springs 24 are arranged inside the slot. A through groove 25 is formed in the middle of the positioning frame 23. A frame body 27 is fixedly installed on the top of the positioning frame 23. A second motor 28 is fixedly installed on one side of the frame body 27. An output shaft of the second motor 28 is fixedly in sleeve joint with a disc 26. The disc 26 runs through the through groove 25. The second motor 28 drives the disc 26 to rotate. Through friction between the disc 26 and the tire, the tire can be driven to rotate. A soaking position at the bottom of the tire body can be changed, and soaking detection at each position can be realized. At the same time, a structure for driving rotation is arranged between the two carrier frames 13, and does not occupy space. At the same time, a telescopic design is adopted, that is, the positioning frame and the guide bar can slide to realize telescoping. The movement between the two carrier frames 13 is not affected. At the same time, the springs 24 between the two carrier frames 13 provide elastic pressure for two ends of the positioning frame 23, the positioning frame 23 is clamped and positioned, and the position of the positioning frame 23 is maintained. It should be noted that the springs 24 are in a completely compressed state during tire installation, and the same elastic pressure can be provided for two ends of the positioning frame 23, so that the position is ensured to realize clamping.

[0038] As shown in FIG. 1 and FIG. 8, as a specific scheme, a fan 8 is arranged on the back of the tire clamping assemblies. The fan 8 is fixedly connected with the supporting column 5. A frame body 801 is fixedly installed on the back of the fan 8. A filter screen 802 is fixedly installed inside the frame body 801. Blowing can be provided by the fan 8, so that the drying of the tire after detection can be facilitated.

[0039] A plurality of counter weights 40 are fixedly installed at the bottom of the detection cell 1, and a drain valve 4 is fixedly installed on one side of the detection cell Ito play a counter weight role. Liquid in the detection cell 1 can be drained through the drain valve 4.

[0040] A fixed mount 16 is fixedly installed on one side of the supporting column 5. A control cabinet 15 is fixedly installed on the fixed mount 16. The control cabinet 15 is electrically connected with the first motor 9, the second motor 28, the third motor 37, the fan 8 and the air cylinder 7. Overall control is carried out through the control cabinet 15. The control cabinet 15 is internally provided with a control circuit, a connecting circuit and a control chip for overall control, and control buttons are arranged on a surface of the control cabinet 15 for manual operation.

[0041] In FIG. 9, the tire in a positioning state is of a circular ring-shaped structure in the figure. The balls 17 in contact with the top inner ring of the tire are transversely distributed as shown in the figure. The balls 17 are transversely distributed in a circular arc shape, that is, the transverse balls 17 are located on the same circular arc line for better contact with the top inner ring of the tire.

[0042] In a using method, when the whole detection device is used, the tire is firstly positioned. The tire is inserted from the bottoms of the two carrier frames 13, so that the top of the tire is in contact with the disc 26. The control cabinet 15 controls the third motor 37. The third motor 37 drives the second circular shaft 31 to rotate, so that the second cylindrical gear 32 rotates. The second cylindrical gear 32 drives the two first cylindrical gears 30 to rotate in opposite directions. The first cylindrical gear 30 is in engaged transmission with the tooth space 20, so that the carrier frame 13 is driven to move. Because the rotating directions of the two first cylindrical gears 30 are opposite, the two carrier frames 13 move in opposite directions. During the moving process, the two carrier frames 13 approach each other under the guidance of the guide rod 21 and the guide hole, so that the top of the tire is positioned and suspended. Atop outer ring of the tire is in contact with the bottom of the disc 26. Aback surface and a front surface of the top of the tire are in contact with the ball 17 on the vertical surface of the carrier frame 13 to realize positioning at front and rear positions. Atop inner ring of the tire is in contact with the ball 17 on the horizontal surface of the carrier frame 13 to realize positioning at upper and lower positions. At the same time, when the second cylindrical gear 32 rotates, the third cylindrical gear 33 is driven to rotate. The two screw rods 38 are driven to rotate. The two screw rods 38 are opposite in threaded rotating directions. At the same time, the screw hole 39 is matched with the screw rod 38. The two screw rods 38 provide driving for the limiting side bars 11 when rotating. The limiting side bars 11 are guided by the guide groove 34 to move left and right. Because the two screw rods 38 are opposite in threaded rotating directions, the two limiting side bars 11 move in opposite directions. The two limiting side bars 11 approach each other, and the rollers 14 are in contact with two sides of the tire, so that a tire body is positioned at left and right positions.

[0043] After positioning, the air cylinder 7 is extended to drive the tire to move, so that the bottom of the tire enters the detection cell 1 and is soaked in detection liquid. The front and bottom of a tire bottom are observed through the transparent observation window 3, so that whether air leakage exists or not is detected. If air bubbles exist, air leaks. If no air bubble exists, the position is in a good condition. After detection, the disc 26 is driven by the second motor 28 to rotate, and the friction between the disc 26 and the top outer ring of the tire drives the tire to rotate, and the soaking position is changed to realize detection of the whole tire.

[0044] After front detection is finished, back detection is carried out. The first motor 9 drives the tire to rotate as a whole, so that positions of two sides of the tire are switched to complete the back detection.

[0045] After detection, the air cylinder 7 is stretched so that the tire moves to the top of the detection cell 1 for draining. In cooperation with the blowing provided by the fan 8, drying is realized, and the tire is taken off after drying to complete detection.

[0046] According to the technical scheme of the present disclosure, improvement is made in the prior art. The tire clamping assemblies can clamp and suspend the tire. At the same time, the tire can be suspended and positioned through the two limiting side bars 11 capable of being adjusted left and right, so that the positioning effect is good. The tire is soaked in the detection cell 1 for detection, and the first motor 9 can drive the tire to rotate, so that front and back positions of the tire under suspension can be changed, and observation of two sides of the tire can be facilitated through the transparent observation window 3. In the tire clamping assemblies, the two carrier frames 13 are driven to approach and separate from each other, and the two limiting side bars 11 are moved to the left and right, synchronous driving can be carried out through driving of the third motor 37. Positioning driving of the tire can be realized at left, right, upper and lower positions only by the third motor 37, and the tire is convenient to use. At the same time, the second motor 28 and the disc 26 can drive the clamped tire to rotate, and the soaking position of the tire in the detection cell 1 can be changed, so that the detection at different positions is facilitated.

[0047] The foregoing descriptions are merely specific embodiments of the present disclosure, but are not intended to limit the present disclosure, and for the skill in the art, the present disclosure can be of various modifications and changes. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
