Technical Field

[0001] This utility model relates to the field of tire mold production technology, specifically a roundness detection device for tire mold production. Background Technology

[0002] In the process of tire mold production and use, in order to prevent the production of substandard tires due to unqualified tire molds, and to prevent the molds from wearing out due to wear after continuous use, which would cause changes in the roundness of the molds and thus reduce product quality, it is necessary to inspect them.

[0003] In the current technology, the roundness of tire molds is mostly detected manually using angle tools, which is cumbersome, the results are not obvious, and the detection error is large, which is not conducive to subsequent tire production. Therefore, it is necessary to improve the roundness detection device for tire mold production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a roundness detection device for tire mold production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roundness detection device for tire mold production, comprising a U-shaped frame, a drawing board arranged on the inner side of the U-shaped frame, four bolts A installed on the internal thread of the drawing board, a detection mechanism arranged inside the U-shaped frame, and a positioning mechanism arranged inside the U-shaped frame.

[0006] Preferably, the detection mechanism includes a motor A, which is fixedly mounted on the top of a U-shaped frame. A rotating shaft is fixedly mounted on the output end of the motor A, and a turntable A is fixedly mounted on the bottom of the rotating shaft. A limit ring is fixedly mounted on the top of the turntable A, and a fixed frame is fixedly mounted on the bottom of the turntable A. A motor B is fixedly mounted on the right end of the fixed frame, and a threaded rod is fixedly mounted on the output end of the motor B. A moving rod is installed on the external thread of the threaded rod, and a mounting block is provided inside the moving rod. A bolt B is installed on the internal thread of the mounting block, and a spring is fixedly mounted inside the mounting block. A slider A is fixedly mounted on the end of the spring away from the mounting block, and a ball bearing is movably mounted inside the slider A. A pen is fixedly mounted on the bottom of the slider A to draw lines.

[0007] Preferably, the paintbrush is movably mounted on the top of the drawing board, the bolt A is threadedly mounted inside the U-shaped frame, and the paintbrush is slidably mounted inside the mounting block, so that the movement of the slider A can drive its movement, thereby making the drawn circle not perfectly round, which facilitates the observation of the test results.

[0008] Preferably, the slider A is slidably installed inside the mounting block, the bolt B is threadedly installed inside the moving rod, the limiting ring is rotatably installed inside the U-shaped frame, the threaded rod is rotatably installed inside the fixed frame, and the moving rod is slidably installed inside the fixed frame, thereby moving the mounting block and enabling the pen to draw a circle.

[0009] Preferably, the positioning mechanism includes a motor C, which is fixedly installed inside the U-shaped frame. A turntable B is fixedly installed at the output end of the motor C. The turntable B has four movable slots inside, and movable columns are movably installed inside the movable slots. A slider B is fixedly installed on the top of the movable column, and an installation shaft is fixedly installed on the top of the slider B. A roller is rotatably installed on the outside of the installation shaft, so that the tire mold can continue to be clamped and positioned when it rotates slightly.

[0010] Preferably, the roller is movably mounted inside the drawing board, and the slider B is slidably mounted inside the U-shaped frame, so that the mounting shaft drives the roller to move.

[0011] Preferably, the turntable B is rotatably mounted inside the U-shaped frame, so that the movable column moves inside the movable slot.

[0012] Compared with the prior art, this utility model provides a roundness detection device for tire mold production, which has the following beneficial effects:

[0013] 1. The roundness detection device for tire mold production uses a ball bearing moving on the outside of the tire mold to draw a circle with a pen. If the outside of the tire mold is not round, the slider A moves the pen, causing obvious jitter in the circle drawing. If the roundness is obviously not round, the next tire mold roundness test can be performed.

[0014] 2. Based on this, the present invention uses motor B to drive the ball bearing away from the tire mold, slightly rotates the tire mold, and offsets the position of the ball bearing that was previously aligned with the tire mold. Then, the fixing frame is activated to reset the ball bearing and draw a circle again. By observing whether the two circles overlap, the roundness of the tire mold is judged, thus completing the tire mold roundness test, which is more rigorous.

[0015] 3. Based on this, the present invention utilizes the cooperation of four rollers so that when the center of the tire mold does not coincide with the center of turntable B, the part of the inner side of the tire mold that is closest to the roller will be pushed by the moving roller, so that the tire mold moves until its center coincides with the center of turntable B, thus completing the installation of the tire mold.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a roundness detection device for tire mold production, including a U-shaped frame 1, a drawing board 2 is provided on the inner side of the U-shaped frame 1, four bolts A3 are installed on the internal thread of the drawing board 2, a detection mechanism 4 is provided inside the U-shaped frame 1, and a positioning mechanism 5 is provided inside the U-shaped frame 1.

[0027] Furthermore, the detection mechanism 4 includes a motor A41, which is fixedly mounted on the top of the U-shaped frame 1. A rotating shaft 42 is fixedly mounted on the output end of the motor A41. A turntable A43 is fixedly mounted on the bottom of the rotating shaft 42. A limit ring 44 is fixedly mounted on the top of the turntable A43. A fixed frame 45 is fixedly mounted on the bottom of the turntable A43. A motor B46 is fixedly mounted on the right end of the fixed frame 45. A threaded rod 47 is fixedly mounted on the output end of the motor B46. A moving rod 48 is installed on the external thread of the threaded rod 47. An installation block 49 is provided inside the moving rod 48. A bolt B410 is installed on the internal thread of the installation block 49. A spring 411 is fixedly mounted inside the installation block 49. A slider A412 is fixedly mounted on the end of the spring 411 away from the installation block 49. A ball bearing 413 is movably installed inside the slider A412. A pen 414 is fixedly mounted on the bottom of the slider A412 to draw lines.

[0028] Furthermore, the pen 414 is movably mounted on the top of the drawing board 2, the bolt A3 is threadedly mounted inside the U-shaped frame 1, and the pen 414 is slidably mounted inside the mounting block 49, so that the movement of the slider A412 can drive its movement, thereby making the drawn circle not round, which makes it easier to observe the test results.

[0029] Furthermore, slider A412 is slidably installed inside mounting block 49, bolt B410 is threadedly installed inside moving rod 48, limit ring 44 is rotatably installed inside U-shaped frame 1, threaded rod 47 is rotatably installed inside fixed frame 45, and moving rod 48 is slidably installed inside fixed frame 45, driving mounting block 49 to move, so that pen 414 draws a circle.

[0030] Example 2:

[0031] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the positioning mechanism 5 includes a motor C51, which is fixedly installed inside the U-shaped frame 1. A turntable B52 is fixedly installed at the output end of the motor C51. Four movable slots 53 are opened inside the turntable B52. Movable columns 54 are movably installed inside the movable slots 53. A slider B55 is fixedly installed on the top of the movable column 54. An installation shaft 56 is fixedly installed on the top of the slider B55. A roller 57 is rotatably installed on the outside of the installation shaft 56, so that the tire mold can continue to be clamped and positioned when it rotates slightly.

[0032] Furthermore, the roller 57 is movably installed inside the drawing board 2, and the slider B55 is slidably installed inside the U-shaped frame 1, so that the mounting shaft 56 drives the roller 57 to move.

[0033] Furthermore, the turntable B52 is rotatably mounted inside the U-shaped frame 1, so that the movable column 54 moves inside the movable slot 53.

[0034] In actual operation, when this device is used, the starter motor C51 drives the turntable B52 to rotate. Since the slider B55 slides inside the U-shaped frame 1, when the turntable B52 rotates, the movable column 54 moves inside the movable groove 53, causing the slider B55 to move. This causes the mounting shaft 56 to drive the roller 57 to retract inward, placing the tire mold inside the U-shaped frame 1. The starter motor C51 then reverses the turntable B52, causing the four rollers 57 to move. When the center of the tire mold does not coincide with the center of the turntable B52, the part of the tire mold that is closest to the roller 57 will be pushed by the moving roller 57, causing... The tire mold is moved until its center coincides with the center of turntable B52, thus completing the installation of the tire mold. Motor B46 is then started, driving the threaded rod 47 to rotate, causing the moving rod 48 to slide inside the fixed frame 45, moving the mounting block 49 until the ball bearing 413 is pressed against the outside of the tire mold. At this point, the spring 411 is compressed, and the slider A412, near the spring 411, is in the middle of the sliding cavity, with room to move to both sides. The paintbrush 414 is positioned at the top of the drawing board 2. Motor A41 is then started, driving the rotating shaft 42 to rotate, causing the turntable A43 to rotate the fixed frame 45, thereby moving the mounting block 49. The pen 414 moves to the top of the drawing board 2 and draws lines. After rotating one full circle, the roundness of the circle drawn by the lines can be observed. If the outside of the tire mold is not round, the ball bearing 413 moves outside the tire mold, causing the slider A412 to move. The spring 411 is initially in a stretched state. The slider A412 moves the pen 414, resulting in obvious jitter in the drawn circle. If it is obviously not round, the roundness test of the next tire mold can be performed. If it is relatively round, the motor B46 is started to move the ball bearing 413 away from the tire mold. The tire mold is slightly rotated to offset the position of the ball bearing 413 that was previously aligned with the tire mold. Then, the fixed frame 45 is activated to reset the ball bearing 413. The motor A41 is started to draw a circle again with the drawing pen 414. By observing whether the two circles overlap, the roundness of the tire mold is judged, thus completing the tire mold roundness test. This avoids the problems of manual inspection using angle tools, which is cumbersome, the test results are not obvious, and the test error is large, which is not conducive to subsequent tire production. The drawing pen 414 and its connected mechanism can be replaced by bolt B410 to avoid the drawing pen 414 breaking ink, resulting in unclear lines and unclear contrast. The drawing board 2 can be replaced by bolt A3 to avoid too many lines causing inconvenience in observation.
