[0002] During tire production, pores in the tire tread need to be machined, or vented when pores become blocked by rubber during use. Existing technology involves manually drilling the pores in the tread block mold with a pistol drill or a pneumatic drill, with the operator visually aligning the holes on the tread block, or by mounting the tread block separately on a machine tool for machining. Due to the specific position and angle of the pores in the tread block, manual visual alignment can easily lead to angle deviations, resulting in poor positioning and angular accuracy and low efficiency.

There are three clamping assemblies, which are distributed on both sides, two on one side and one on the other side. The clamping assemblies are arranged on the rotating rod 3. The three clamping assemblies are used to fix the tire tread block mold. The driving assembly is arranged on the vertical plate 4, and the driving assembly is used to drive the three clamping assemblies to work. During the process of rotating the clamping plate 11 to clamp the tire tread block mold, the clamping plate 11 can automatically and adaptively adjust the length and angle of extension, so that it can stably clamp the tire tread block mold at any position.

[0021] Please see the attached Figure 1 -Attached Figure 7 In a preferred embodiment, the clamping assembly includes: a collar 8, which is rotatably sleeved on the surface of the rotating rod 3, and an open box 9 is fixedly installed on the surface of the collar 8, the bottom of the open box 9 is open, and a connecting plate 10 is slidably arranged inside the open box 9, and a first T-slot 22 and a second T-slot 23 are opened inside the connecting plate 10, and the first T-slot 22 and the second T-slot 23 pass through the top of the connecting plate 10, and a sliding post 24 is movably installed inside the first T-slot 22 and the second T-slot 23, and a limiting rod 16 is slidably provided inside the first T-slot 22, and the end of the limiting rod 16 is fixedly installed at the top of the corresponding sliding post 24, and the inside of the horizontal side of the second T-slot 23 is connected with a screw 15 by a thread, and the end of the screw 15 is fixedly installed at the top of the corresponding sliding post 24, and the top of the limiting rod 16 is fixedly installed on the open box 9 The inner top, and the top of the screw 15 is rotatably mounted on the inner top of the open box 9, the surface of the screw 15 is fixedly sleeved with a second bevel gear 20, the side of the second bevel gear 20 is meshed with a first bevel gear 19, and the center of the end face of the first bevel gear 19 is fixedly mounted with a rotating shaft 18, the other end of the rotating shaft 18 is rotatably mounted on the inner wall of the open box 9, and the outside of the open box 9 is rotatably mounted with a second gear 17, the end face of the second gear 17 is fixedly mounted at the center of the end face of the rotating shaft 18 through a connecting shaft, a toothed disc 12 is fixedly sleeved on the surface of the rotating rod 3, and the toothed disc 12 is meshed with the second gear 17, a shaft 21 is rotatably mounted on the end of the connecting plate 10, and a splint 11 is fixedly mounted on the surface of the shaft 21, a first gear 14 is fixedly mounted on the end of the shaft 21, a rack 13 is fixedly mounted on the inner wall of the open box 9, and the first gear 14 is meshed with the rack 13; When it is necessary to clean the pores on the tire tread block mold, first place the tire tread block mold on the four slope blocks 2; Then the driving assembly works to drive the open box 9 to move. Since the open box 9 is limited by the collar 8, the open box 9 will rotate with the rotating rod 3 as the center. The rotation of the open box 9 drives the components on it to rotate with the rotating rod 3 as the center. Due to the arrangement of the toothed disc 12, when the second gear 17 revolves around the rotating rod 3, it also rotates. The rotation of the second gear 17 drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the screw 15 to rotate. The rotation of the screw 15 drives the connecting plate 10 to move inside the opening box 9. The connecting plate 10 moves through the shaft 21 to drive the clamping plate 11 and the first gear 14 to move, so that the extended length of the clamping plate 11 can be adaptively and automatically adjusted during the process of clamping the tire tread block mold, so that it can adapt to tire tread block molds of different specifications, ensuring that when clamping tire tread block molds of different specifications, there is a clamping plate 11 with a length that is exactly adapted to clamp the tire tread block mold, thereby ensuring the clamping effect of the clamping plate 11 on the tire tread block mold; Due to the setting of the rack 13, the first gear 14 will also rotate when it moves. The rotation of the first gear 14 will drive the clamping plate 11 to rotate, so that the clamping plate 11 can automatically adjust the angle adaptively when following the rotation, ensuring that when clamping tire tread block molds of different specifications, the angle of the clamping plate 11 can be the same as the angle of the tire tread block molds of different specifications, avoiding the situation where the angle of the clamping plate 11 is fixed or the angle of the clamping plate 11 needs to be adjusted independently, and then the tire tread block mold vent can be adjusted, and the tire tread block mold has a good fixing effect, further improving the effect of the tire tread block mold vent.

[0022] Please see the attached Figure 1 -Attached Figure 7 In a preferred embodiment, the driving assembly includes: a first L-shaped frame 5, the first L-shaped frame 5 is fixedly installed on one side of the vertical plate 4, the long side of the first L-shaped frame 5 is hinged with a first cylinder 7, and the telescopic end of the first cylinder 7 is hinged to the surface of the corresponding opening box 9, and the other side of the vertical plate 4 is fixedly installed with a second L-shaped frame 6, the long side of the second L-shaped frame 6 is hinged with two second cylinders, and the telescopic ends of the two second cylinders are hinged to the surfaces of the other two opening boxes 9; The first cylinder 7 and the second cylinder are driving sources, which are used to enable the four opening boxes 9 to rotate around the rotating rod 3, further facilitating the opening boxes 9 to drive the three clamping plates to clamp and position the tire tread block mold; Specifically: start the first cylinder 7 and the second cylinder, and the first cylinder 7 and the second cylinder work to drive the open box 9 to move. Since the open box 9 is limited by the ring 8, the open box 9 will rotate with the rotating rod 3 as the center of the circle. The rotation of the open box 9 drives the components on it to rotate with the rotating rod 3 as the center of the circle.

[0023] Please see the attached Figure 1In a preferred embodiment, a ramp block 2 is fixedly installed on the top of the base 1. There are four ramp blocks 2, which are symmetrically arranged to receive the tire tread block mold. The four slope blocks 2 are used to support the tire tread block mold, which not only facilitates the placement of the tire tread block mold, because the tire tread block mold is arc-shaped and placed directly on the base 1, the tire tread block mold will swing left and right, and also facilitates the subsequent vent holes of the tire tread block mold.

[0024] In summary, in the process of rotating the clamping plate 11 to clamp the tire tread block mold, the clamping plate 11 can adaptively and automatically adjust the extended length and angle, so that it can stably clamp the tire tread block mold at any position, thereby improving the use effect of the equipment.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
