[0014] Compared with the existing tire mold detection device, the present invention provides a tire mold detection device with adjustable multi - sizes, having the following beneficial effects:

[0015] 1. The present invention is provided with a tightening module. The base of the tire mold is of a ring structure. By controlling the telescopic motor, the rubber - coated tightening wheel can be telescoped to automatically adjust the position of the rubber - coated tightening wheel, so that it is in fixed contact with the inner - side section of the ring of the tire mold base, playing a role of positioning and fixing. The rubber - coated tightening wheel has good elasticity and shock - absorption performance, which can effectively absorb the vibration and impact generated during operation, avoid the jitter of the tire mold detection device during operation, and thus make the operation of the tire mold detection device more stable.

[0016] 2. The present invention is provided with a lead screw Ⅰ and a lead screw Ⅱ with the same specification but opposite thread directions. The two sides of the worm gear are fixedly connected to the lead screw Ⅰ and the lead screw Ⅱ with opposite thread directions through flanges. The rotation of the worm gear drives the rotation of the lead screw Ⅰ and the lead screw Ⅱ, which can respectively drive two sliders Ⅰ to reciprocate and telescopically move in the opposite direction for the same stroke, making the movement of the tightening module more stable and reducing impact and vibration.

[0017] 3. The present invention is provided with an H - groove bearing. The bearing in the groove of the H - groove bearing is closely attached to the outer wall of the cylindrical gear ring, and the bearing groove clamps and extrudes the outer end face of the cylindrical gear ring, playing a role of limiting the cylindrical gear ring, so as to ensure the stable rotation of the cylindrical gear ring and the rotation module.

[0018] 4. The present invention is provided with a rotation module. Four sets of rotating rollers and roller shafts are deployed around the rotating base. The rotating rollers are in contact with the upper - end face of the ring of the tire mold base, which can play a supporting role. The rotation of the rotation module can make the rotating base drive the rotating rollers to roll smoothly on the upper - end face of the ring of the tire mold base, so that the lifting column module and the detection length adjustment module fixed on the rotation module are more stable when rotating, ensuring the stability of the rotation of the camera module, and further improving the detection accuracy of the tire mold.

[0019] 5. The present invention is provided with a lifting column module and a detection length adjustment module. The rotation of the ball screw can be driven by a motor, and then drive the screw nut and the detection length adjustment module to lift, controlling the height of the detection length adjustment module. While driving the screw nut and the detection length adjustment module to lift, the detection length adjustment module drives the moving plate of the detection length adjustment module and the camera module fixedly connected thereto to move horizontally through the motor - driven synchronous belt. Through lifting and horizontal movement, the pose of the camera module can be accurately adjusted, and the pose of the camera module can be flexibly controlled, so that it can meet the detection pose requirements of tire molds of different sizes, and further realize the adjustable size of the tire mold detection device, meeting the defect detection requirements of tire molds of different models.

[0020] 6. The detection length adjustment module of the present invention fixes the upper and lower belt clips of the synchronous belt to the moving plate and the base of the detection length adjustment module respectively, and the motor of the detection length adjustment module is fixedly connected to the intermediate moving plate of the detection length adjustment module. It can realize that while the moving plate of the detection length adjustment module moves horizontally, the intermediate moving plate of the detection length adjustment module also moves horizontally, achieving double-stroke detection length adjustment for the camera module, so as to meet the detection requirements of some relatively large tire molds. Moreover, the double-stroke detection length adjustment structure can reduce the volume of the tire mold detection device. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating base 21 rotates, the rotating rollers 211 are in contact with the upper end surface of the tire mold base ring.

[0035] As Figure 6 shown in the figure, the lifting column module 4 includes: a lead screw bearing seat 41, a lead screw III 42, a trapezoidal nut 43, a coupling II 44, a lifting motor 45, a limit block II 46, a slider III 47, a column 48, and a column bracket 49. The lifting motor 45 is connected to the lead screw III 42 by the coupling II 44; the bottom end of the lead screw II 42 is connected to the lead screw bearing seat 41 by a thrust ball bearing; the lead screw bearing seat 41 is fixedly connected to the column 48 by bolts; the column 48 is fixedly connected to the column bracket 49 and the limit block II 46 by bolts; the slider III 47 is fixedly connected to the trapezoidal nut 43 by bolts; the trapezoidal nut 43 is threadedly connected to the lead screw III 42; the trapezoidal nut 43 is fixedly connected to the detection length adjustment module 5 by bolts; the lifting motor 45 drives the lead screw III 42 to rotate to drive the trapezoidal nut 43 and the detection length adjustment module 5 to lift, which can control the height of the detection length adjustment module 5 to meet the detection height requirements of tire molds of different sizes and models.

[0036] As Figure 7 andFigure 8 As shown in the figure, the detection length adjustment module 5 includes a synchronous belt driving pulley 51, a detection length adjustment module motor 52, a motor bracket III 53, a slider IV 54, a slider V 55, a detection length adjustment module intermediate moving plate 56, a pulley mounting plate 57, a synchronous belt driven pulley 58, a belt clip I 59, a detection length adjustment module moving plate 510, a synchronous belt 511, a belt clip II 512, and a detection length adjustment module base 513. The top of the slider IV 54 is fixedly connected to the detection length adjustment module intermediate moving plate 56 by bolts. The detection length adjustment module intermediate moving plate 56 is fixedly connected to the motor bracket III 53, the pulley mounting plate 57, and the guide rail by bolts. The motor bracket III 53 is fixedly connected to the detection length adjustment module motor 52 by bolts. The detection length adjustment module motor 52 is key-connected to the synchronous belt driving pulley 51 to drive the synchronous belt driving pulley 51 to rotate.

Since the belt clip I 59 is fixedly connected to the detection length adjustment module base 513, the lower belt of the synchronous belt cannot be transmitted back and forth. When the upper belt of the synchronous belt moves forward, the tension force generated by the synchronous belt drives the synchronous belt driving pulley 51 to move horizontally forward, thereby driving the detection length adjustment module motor 52 and the detection length adjustment module intermediate moving plate 56 to move horizontally forward. The moving stroke of the detection length adjustment module intermediate moving plate 56 is half of the stroke of the detection length adjustment module moving plate 510. When the upper belt of the synchronous belt moves backward, the tension force generated by the synchronous belt drives the synchronous belt driven pulley 58 to move horizontally backward, thereby driving the detection length adjustment module motor 52 and the detection length adjustment module intermediate moving plate 56 to move horizontally backward. The moving stroke of the detection length adjustment module intermediate moving plate 56 is half of the stroke of the detection length adjustment module moving plate 510. Therefore, only one detection length adjustment module motor 52 can enable the detection length adjustment module moving plate 510 to achieve a double-stroke horizontal movement, realizing the double-stroke detection length adjustment of the camera module, so as to be able to meet the detection requirements of tire molds with different sizes, and the volume of the tire mold detection device can be reduced through the structure of the double-stroke detection length adjustment.
