[0019] This utility model provides the following technical solution:

[0020] Example 1, please refer to Figure 1 :

[0021] A roundness detection device for tire molds includes a base 1, an annular plate 2 rotatably connected to the upper surface of the base 1, and a driving mechanism provided on the rear side of the annular plate 2. Three movable frames 3 arranged in a triangular array are rotatably connected to the upper surface of the annular plate 2, and movable plates 4 slide through the inner cavity of the movable frames 3. A rotating shaft 5 is rotatably connected to the bottom of each movable plate 4, and the bottom end of the rotating shaft 5 is rotatably connected to the top of the base 1. A rotating rod 6 is vertically fixed through the other side of each movable plate 4, and a limiting roller 7 is rotatably connected to the top end of the rotating rod 6. A circular surface can be determined by the three limiting rollers 7 that are not on the same straight line, so that tire molds of different sizes can be clamped. A cavity 15 is preset in the middle of the base 1, and a horizontal plate 20 is fixedly connected to the inner cavity of the cavity 15 near the bottom.

[0022] The driving mechanism includes an annular rack plate 9, which is sleeved and fixed on the outer wall of annular plate 2. A movable rack 10 is engaged on the rear side of the annular rack plate 9, and the movable rack 10 is slidably connected to the top of the base 1. A threaded sleeve 11 is provided on the back side of the movable rack 10, and a threaded rod 12 is threadedly connected to the inner cavity of the threaded sleeve 11. Fixed plates 13 are provided on the left and right sides of the top of the base 1, and second bearings are provided on the fixed plates 13. The left and right ends of the threaded rod 12 pass through the inner cavities of the adjacent second bearings and are fixedly connected to rocker arms 14. By rotating the rocker arm 14, the threaded rod 12 is rotated. The rotation of the threaded rod 12 causes the movable rack 10 to move horizontally and rotates the annular rack plate 9. The rotation of the annular rack plate 9 causes the annular plate 2 to rotate, and the movable plate 4 is driven by the movable frame 3 to deflect around the rotating shaft 5, so that the three limiting rollers 7 are gathered together to clamp the tire mold, thereby improving the stability during the inspection operation.

[0023] The bottom end of the rotating rod 6 is connected to a ball bearing 8, and the bottom of the ball bearing 8 is fitted to the upper surface of the base 1. When the movable plate 4 rotates, the ball bearing 8 can roll on the top of the base 1, thereby improving the stability of the limiting roller 7 during deflection movement.

[0024] Working principle: When using this utility model, the tire mold is first placed into the inner cavity of the annular plate 2. Then, the rocker arm 14 on one side is rotated, which drives the threaded rod 12 to rotate, thereby driving the threaded sleeve 11 to move horizontally and the moving rack 10 to move horizontally. The movement of the moving rack 10 drives the annular rack plate 9 to rotate, which in turn drives the annular plate 2 to rotate. The rotation of the annular plate 2 causes the movable frame 3 to deflect, thereby pressing the movable plate 4 together and driving the limiting roller 7 to clamp the tire mold. This allows for the fixing of tire molds of different sizes, which not only improves the practicality of the device but also improves the accuracy of the device's detection.

[0025] Example 2, please refer to Figures 1 to 3 :

[0026] A through groove 16 communicating with the inner cavity of cavity 15 is provided at the top center of base 1, and a square hole tube 19 is rotatably connected to the center of the inner cavity of through groove 16. The top end of square hole tube 19 is fixedly connected to mounting plate 17, and a detector 18 is provided on the top of mounting plate 17. Several exhaust holes 39 are vertically and equidistantly provided on the outer wall of square hole tube 19. An electric rod 21 is provided on the top of horizontal plate 20, and a turntable 22 is fixedly connected to the power end of electric rod 21. A first bearing is provided on turntable 22, and the bottom end of square hole tube 19 passes through the inner cavity of the first bearing. The turntable 22 is driven to move vertically up and down by electric rod 21, thereby driving detector 18 to move vertically, so as to detect the roundness of different depth areas of the inner cavity of tire mold, improve the sufficiency of detection. An air intake mechanism is provided at the bottom of square hole tube 19, and a dust suction mechanism is provided in the inner cavity of annular plate 2.

[0027] The intake mechanism includes a square tube with a round hole 23, the outer diameter of which is adapted to the inner diameter of the square tube 19. The square tube 23 is slidably inserted into the bottom end of the inner cavity of the square tube 19, and a rotating sleeve 24 is fixedly fitted onto the outer wall of the square tube 23. A round hole adapted to the rotating sleeve 24 is provided on the horizontal plate 20, and the bottom end of the rotating sleeve 24 penetrates the inner cavity of the round hole and extends to the bottom of the horizontal plate 20. Two limiting rings 25 are fixedly fitted onto the outer wall of the rotating sleeve 24, and the two limiting rings 25 are respectively fitted to the upper and lower surfaces of the horizontal plate 20. A sealing ring 32 is slidably fitted into the inner cavity of the square tube 23, and the inner surface of the sealing ring 32 is... An air supply pipe 31 is fixedly installed through the cavity. The sealing effect of the air supply pipe 31 and the square tube 23 with round hole is improved by the setting of the sealing ring 32. An air pump 29 is set at the bottom of the cavity 15 near the left side, and the other end of the air supply pipe 31 is fixedly connected to the air pump 29. An air extraction pipe 33 is fixedly connected to the left side of the air pump 29, and the other end of the air extraction pipe 33 penetrates the left side wall of the base 1 and extends to the outside. By operating the air pump 29, outside air can be drawn into the cavity of the square tube 19 and blown towards the inner wall of the tire mold through the exhaust hole 39, thereby blowing away the dust adhering to the inner wall of the tire mold and thus cleaning the tire mold.

[0028] A pressurizing pump 30 is connected to the air supply pipe 31, and the pressurizing pump 30 is fixedly connected to the bottom of the inner cavity of the cavity 15. The pressurizing pump 30 pressurizes the air flowing in the inner cavity of the air supply pipe 31, thereby increasing the air pressure in the inner cavity of the square hole round pipe 19, and the air discharged from the exhaust hole 39 is blown towards the inner wall of the tire mold after being pressurized, thereby improving the cleaning effect on the inner cavity of the tire mold.

[0029] A drive motor 27 is installed at the top right side of the horizontal plate 20, and a transmission gear 28 is fixedly connected to the power end of the drive motor 27. A driven gear 26 that meshes with the transmission gear 28 is sleeved and fixed on the outer wall of the rotating sleeve 24. The drive motor 27 drives the transmission gear 28 to rotate and drives the driven gear 26 to rotate, thereby driving the rotating sleeve 24 to rotate. The rotation of the rotating sleeve 24 drives the round hole square tube 23 to rotate, and the rotation of the round hole square tube 23 drives the square hole round tube 19 to rotate. This can drive the detector 18 to rotate for all-round detection, and at the same time, it can also thoroughly clean the inner wall of the tire mold.

[0030] The dust collection mechanism includes two dust collection hoods 34, which are respectively located on the left and right sides of the inner cavity of the annular plate 2. The top of the base 1 has a fixing groove adapted to the two dust collection hoods 34, and the two dust collection hoods 34 are respectively located in the inner cavities of adjacent fixing grooves. A suction pipe 35 is inserted and fixed to the bottom of each dust collection hood 34, and the bottom end of the suction pipe 35 extends into the inner cavity of the cavity 15 and is fixedly connected to a suction pump 36. Both suction pumps 36 are fixedly installed on the top of the horizontal plate 20. Dust pump 36 is fixedly connected to dust discharge pipe 37 on both opposite sides. Dust collection boxes 38 are provided on both the left and right sides of the base 1. The other ends of the two dust discharge pipes 37 are respectively inserted and fixed to the outer wall of the adjacent dust collection box 38 and respectively connected to the inner cavity of the adjacent dust collection box 38. Through the operation of the dust pump 36, the dust raised in the inner cavity of the tire mold can be absorbed and discharged into the dust collection box 38, thereby avoiding secondary pollution caused by the raised dust. At the same time, it is convenient for staff to clean the dust collected in the dust collection box 38.

[0031] Working Principle: In use, after the tire mold is fixed, the electric lever 21 pushes the turntable 22 to move up and down, thereby adjusting the height of the detector 18. The drive motor 27 drives the transmission gear 28 to rotate, which in turn drives the driven gear 26 to rotate. The driven gear 26 then drives the rotating sleeve 24 to rotate, which in turn drives the round-hole square tube 23 to rotate. The round-hole square tube 23 then drives the square-hole round tube 19 to rotate, which in turn drives the mounting plate 17 to rotate, and consequently, the detector 18 to rotate horizontally. This allows for the inspection of the tire mold's inner cavity. After the inspection is completed... Simultaneously, the air pump 29, the pressurizing pump 30, and the dust pump 36 are started. The air pump 29 and the pressurizing pump 30 pressurize the air drawn into the inner cavity of the air inlet pipe 31 and deliver it into the inner cavity of the square hole round pipe 19. The air is then blown towards the inner wall of the tire mold through the exhaust port 39. The rotation of the square hole round pipe 19 can thoroughly clean the inner wall of the tire mold by blowing away dust. The operation of the dust pump 36 can suck up the dust that is raised through the dust suction pipe 35 and the dust collection hood 34, and discharge it into the dust collection box 38 through the dust discharge pipe 37. This not only avoids secondary pollution caused by the raised dust, but also makes it easier for the staff to clean the dust in the dust collection box 38.
