Description

Technical Field

[0001] The utility model relates to the technical field of tire mold pattern detection. More specifically, the utility model relates to a simple tooling for quickly detecting the symmetry of tire mold pattern blocks. Background Technique

[0002] A tire mold is a mold used for vulcanizing and molding various tires. Generally, a tire mold is assembled from parts with different functions. Among the components of a tire mold, a pattern block is the main tool for manufacturing tire patterns. The patterns of tires can increase the friction between the tread and the road surface to prevent the wheels from slipping. However, different depths of the symmetry points of the pattern block will generate a taper, which may lead to a reduction in the contact area between the tire and the ground, thereby reducing the grip. This will affect the handling performance of the vehicle. Especially in wet or emergency braking situations, it may cause the vehicle to lose control. To solve this problem, a tool for detecting the symmetry of tire mold pattern blocks is needed.

[0003] Chinese Patent with the patent announcement number CN213902211U discloses a simple tooling for quickly detecting the symmetry of tire mold pattern blocks. The device measures the width of the tire mold pattern block accurately by designing a main bracket with a scale value and a fixed bracket with a zero position set, and a movable fixing device is arranged at the other end of the main bracket to obtain the midpoint position; the positions of the upper and lower symmetry points are found through the midpoint. Secondly, through a slider equipped with a digital display dial indicator, the depth values of the upper and lower symmetry point positions are accurately detected, realizing the rapid and accurate measurement of whether there is a taper at the symmetry points of the pattern block.

[0004] However, in actual use, during the process of measuring the symmetry points with this tooling, it is necessary to obtain the midpoint after measuring the width of the tire, and then detect whether the depths of the symmetry points are the same through the midpoint, which is time-consuming and laborious, resulting in an increase in the workload of the staff. At the same time, the two symmetry points need to be moved twice respectively, and it is difficult to ensure that the two moving distances are exactly the same, resulting in inaccurate measurement accuracy.

[0024] As shown in the attached Figures 1-4 A simple tooling for quickly detecting the symmetry of the pattern block 11 of a tire mold, including a main bracket 1. A two-way measurement structure is arranged outside the main bracket 1. The two-way measurement structure includes two positioning blocks 2 fixedly installed at the top of the main bracket 1, and the two positioning blocks 2 are symmetric with each other. A first double lead screw 3 is rotatably connected between the two positioning blocks 2. Two threaded blocks 4 are threadedly connected to the outside of the first double lead screw 3, and the two threaded blocks 4 are symmetric with each other. One end of each of the two threaded blocks 4 is fixedly connected to a micrometer 5;

[0025] One end of the first double lead screw 3 is fixedly connected to a T-shaped rod 6;

[0026] A moving groove 7 is opened inside the main bracket 1, and the micrometer 5 is slidably connected to the moving groove 7.

[0027] In a specific embodiment, as shown in the attached Figure 1 As shown, a plurality of scale bars 8 are installed on the surface of the main bracket 1, and the tops of the scale bars 8 are on the same horizontal plane as the top of the main bracket 1, so as to quickly detect the width of the pattern block 11.

[0028] Specifically, in this structure, after the staff clamps the pattern block 11, the width of the pattern block 11 can be quickly read.

[0029] In a specific embodiment, as shown in the attached Figure 2 figure, a clamping structure is provided inside the main bracket 1. The clamping structure includes a T-shaped groove 9 opened inside the main bracket 1. Two T-shaped blocks 10 are slidably connected inside the T-shaped groove 9. A pattern block 11 is arranged between the two T-shaped blocks 10 to facilitate the quick clamping of the pattern block 11.

[0030] Specifically, in this structure, the T-shaped blocks slide inside the T-shaped groove 9 to clamp the pattern block 11.

[0031] In a specific embodiment, as shown in the attached Figure 4 figure, a second bidirectional lead screw 12 is threadedly connected between the two T-shaped blocks 10. One end of the second bidirectional lead screw 12 is rotatably connected to the main bracket 1, and the other end of the second bidirectional lead screw 12 penetrates through the main bracket 1 and extends to the outside of the main bracket 1 to facilitate the movement of the T-shaped blocks 10 to both sides.

[0032] Specifically, in this structure, the two symmetric T-shaped blocks 10 move to both sides simultaneously under the rotation of the second bidirectional lead screw 12.

[0033] In a specific embodiment, as shown in the attached Figure 1 figure, a rotating disk 13 for rotating the second bidirectional lead screw 12 is fixedly connected to the end of the second bidirectional lead screw 12 away from the main bracket 1 to facilitate the staff to rotate the second bidirectional lead screw 12.

[0034] Specifically, in this structure, the staff rotates the rotating disk 13, and the rotating disk 13 drives the second bidirectional lead screw 12 to rotate.

[0035] In a specific embodiment, as shown in the attached figure, a bubble level for detecting the levelness is installed on the side of the main bracket 1. Figure 3

[0036] Specifically, in this structure, the guide rod 14 guides the movement of the threaded block 4 to both sides or inward.

[0037] In a specific embodiment, as shown in the attached figure, a bubble level for detecting the levelness is installed on the side of the main bracket 1.

[0038] Working principle of the utility model: First, the staff rotates the rotating disk 13, and the rotating disk 13 drives the second double-headed screw rod 12 to rotate. The rotation of the second double-headed screw rod 12 drives the rotation of two symmetrical T-shaped blocks 10. Under the restriction of the T-shaped groove 9, the two symmetrical T-shaped blocks 10 move simultaneously to both sides inside the T-shaped groove 9. Then, the simple tooling is placed above the pattern block 11. At the same time, the staff judges whether the tooling is placed horizontally by observing the bubble level. By rotating the rotating disk 13, the two T-shaped blocks 10 move simultaneously towards the inside on the second double-headed screw rod 12 to clamp the pattern block 11. At the same time, the scale bar 8 on the main support 1 can measure the width of the pattern block 11. After measuring the width of the pattern block 11, the corresponding position of the center point of the pattern block 11 on the scale bar 8 can be obtained through quick calculation to ensure the accuracy of the measurement data. After that, rotate the T-shaped rod 6, and the T-shaped rod 6 drives the first double-headed screw rod 3 to rotate inside the two positioning blocks 2. At the same time, under the guidance of the guide rod 14, the two symmetrical threaded blocks 4 threadedly connected to the surface of the first double-headed screw rod 3 move respectively to both sides on the first double-headed screw rod 3. When the two threaded blocks 4 move to both sides, they drive the dial indicators 5 to move to both sides. At the same time, moving the dial indicators 5 saves the working time of the staff and improves work efficiency. The two dial indicators 5 moving to both sides simultaneously can quickly locate two symmetrical points. At the same time, the dial indicators 5 allow the staff to quickly read the data. If the data of the two dial indicators 5 are the same, it means that the positions of the symmetrical points are the same and there is no taper. If the symmetrical positions of the two dial indicators 5 are the same but the dial data is different, it means that there is taper, achieving the effect of quick detection.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
