[0032] As Figures 1-4 shown, the present utility model provides a detection device for a tire mold, having a detection table 1. Among them, a placement plate 2 is rotatably connected to the detection table 1. Four slideways 21 that form a 90° angle with each other are provided on the placement plate 2. A sliding block 22 is slidably connected to each of the slideways 21. An arc-shaped plate 23 for clamping the tire mold is fixedly installed on the top wall of each sliding block 22;

[0033] Above the placement plate 2, there is a telescopic cylinder 3 that moves horizontally. A sliding sleeve 31 is fixedly installed on the movable end of the telescopic cylinder 3. A slide bar 32 is horizontally slidably connected to the sliding sleeve 31;

[0034] The left end of the slide bar 32 is fixedly installed with an L-shaped plate 33. A spring 30 is fixedly installed between the L-shaped plate 33 and the sliding sleeve 31. The bottom end of the L-shaped plate 33 is rotatably connected to a rotating rod 34. A roller 35 that abuts against the circumferential surface of the tire mold is fixedly installed in the middle of the bottom wall of the rotating rod 34.

[0035] Optionally, in the above technical solution, the bottom wall of the placement plate 2 is rotatably connected to a rotating plate 24 arranged concentrically therewith. The rotating plate 24 is of a rectangular structure, and a positioning post A25 is fixedly installed at each of the four corners. A positioning sleeve A26 is rotatably connected to each positioning post A25.

[0036] Optionally, in the above technical solution, a positioning post B27 is fixedly installed at the inner end of the middle part of the bottom wall of the I-shaped block 22. A positioning sleeve B28 is rotatably connected to each positioning post B27. One end of an L-shaped rod 29 is fixedly installed on the positioning sleeve A26, and the other end of the L-shaped rod 29 is fixedly installed on the positioning sleeve B28.

[0037] Optionally, in the above technical solution, the bottom end of the placement plate 2 is fixedly installed on a support circular plate 42 through two symmetrically arranged connecting rods 41. A first groove 11 is opened in the middle of the top wall of the detection table 1. A reduction motor A4 is fixedly installed in the first groove 11. A lower rotating rod 40 is fixedly installed in the middle of the bottom wall of the support circular plate 42. The output shaft of the reduction motor A4 is fixedly connected to the lower rotating rod 40 through a coupling.

[0038] Optionally, in the above technical solution, a reduction motor B43 is fixedly installed in the middle of the top wall of the support circular plate 42. An upper rotating rod 44 is fixedly installed in the middle of the bottom wall of the rotating plate 24. The output shaft of the reduction motor B43 is fixedly connected to the upper rotating rod 44 through a coupling.

[0039] Optionally, in the above technical solution, a support frame 5 in an inverted "U" shape is fixedly installed on the top wall of the detection table 1 and located outside the placement plate 2. A second groove 50 arranged horizontally is opened at the bottom wall of the upper end of the support frame 5. A screw rod 51 is rotatably connected in the second groove 50. A nut block 52 is sleeved on the outer circumference of the screw rod 51 and is threadedly connected thereto. The nut block 52 is slidably connected in the second groove 50 and is fixedly connected to the fixed end of the telescopic cylinder 3.

[0040] Optionally, in the above technical solution, a through groove is opened on the support frame 5 at the rear end of the telescopic cylinder 3. A drawing board 37 is inserted in the through groove. A paintbrush 36 is fixedly installed at the right end of the rear wall of the sliding rod 32. The tip of the paintbrush 36 abuts against the drawing board 37.

[0041] Further, one end of the screw rod 51 is rotatably connected to the left wall of the second groove 50, and a reduction motor C53 is fixedly installed on the right wall of the second groove 50. The output shaft of the reduction motor C53 extends leftward and is fixedly connected to the other end of the screw rod 51 through a coupling.

[0042] Among them, during detection, the inner arc surface of the arc-shaped plate 23 is abutted against the outer circumferential surface of the tire mold, or the outer arc surface of the arc-shaped plate 23 is abutted against the inner circumference of the tire mold.

[0043] Among them, limit plates 291 are fixedly installed on the bottom walls of positioning posts A25 and B27 to prevent positioning sleeves A26 and B28 from sliding up and down.

[0044] Among them, the front wall of the drawing board 37 abuts against the tip of the paintbrush 36.

[0045] Among them, the L-shaped plate 33 is pushed under the elastic force of the spring 30, so that the roller 35 is always in contact with the surface of the tire mold, and the spring 30 is always in a state of not being stretched.

[0046] When detecting the inner ring of the tire mold, the roller 35 abuts against the left end of its inner circumferential surface. When detecting the outer ring of the tire mold, the roller 35 abuts against the right end of its outer circumferential surface.

[0047] During use, according to the outer diameter (or inner diameter) of the tire mold to be detected, the position of the arc-shaped plate 23 is initially adjusted. After adjustment, the tire mold is placed on the placement plate 2 so that its bottom wall contacts the top wall of the I-shaped block 22. Then, the arc-shaped plate 23 is adjusted again until the arc-shaped plate 23 retracts to clamp the tire mold (or the arc-shaped plate 23 moves outward to press against the tire mold) to prevent the tire mold from moving;

[0048] At this time, start the reduction motor C53 to make the screw rod 51 rotate in place, so that the screw block 52 drives the telescopic cylinder 3 to move horizontally until the telescopic cylinder 3 makes the roller 35 abut against the outer circumferential surface (or inner circumferential surface) of the tire mold. At this time, insert the drawing board 37 into the support frame 5;

[0049] Start the reduction motor A4 to drive the support circular plate 42 to rotate in place through the lower rotating rod 40. The support circular plate 42 drives the placement plate 2 to rotate through the connecting rod 41, so that the tire mold on the placement plate 2 rotates in place for one circle;

[0050] The rotation of the tire mold makes its outer circumferential surface (or inner circumferential surface) rotate relative to the roller 35. When the uneven position of the tire mold abuts against the roller 35, the spring 30 will be compressed or rebound to drive the paintbrush 36 to move horizontally. By observing the line drawn by the paintbrush 36 on the drawing board 37, the roundness of the outer circumferential surface (or inner circumferential surface) of the tire mold can be judged;

[0051] The adjustment method of the arc-shaped plate 23 is as follows: start the reduction motor B43 to drive the rotating plate 24 to rotate in place through the upper rotating rod 44. The rotating plate 24 drives the positioning post A25 to rotate, and thus drives one end of the L-shaped rod 29 to move through the positioning sleeve A26. The other end of the L-shaped rod 29 drives the positioning post B27 to move through the positioning sleeve B28. The positioning post B27 drives the I-shaped block 22 to slide along the slideway 21, so that the four arc-shaped plates 23 move simultaneously.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
