Technical Field
[0001] This utility model relates to a tread grooving device for all-steel radial tires, belonging to the technical field of tire grooving devices. Background Technology
[0002] Radial tires are a type of tire structure, distinct from bias-ply tires, arched tires, and adjustable-pressure tires. The international designation for radial tires is "R," and they are commonly known as "steel-belted tires." When grooving the tread of a radial tire, a grooving device is required.
[0003] According to CN221021198U, a tire tread grooving device is disclosed, belonging to the field of tire production technology. It includes a base, an adjustment component installed on the vertical side wall of the top of the base, and an adjustment plate connected to the side of the adjustment component. The horizontal end of the adjustment plate is connected to a support plate through several connecting plates. A servo motor is fixed at the end of the support plate near the adjustment plate, and the drive end of the servo motor passes through the support plate and is connected to a fixing structure for fixing the tire. A stepper motor is installed on the side of the base away from the adjustment component, and the top of the base is provided with an adjustment groove for limiting the movement. A second lead screw is installed inside the adjustment groove, and a movable block connected to the adjustment groove is threaded to the side of the second lead screw. One end of the second lead screw passes through the adjustment groove and is connected to the drive end of the stepper motor. This tire tread grooving device can control the spacing between grooves and the number of grooves, and can be adjusted according to actual conditions, thus expanding the device's applicability. However, although the position of the grooving blade can be adjusted to make it suitable for grooving tires of different specifications, each tire requires multiple grooving operations to complete the job, resulting in low production efficiency. Furthermore, the inclusion of multiple electric push rods increases the probability of device damage, thus reducing the device's practicality. Utility Model Content
[0004] The purpose of this invention is to provide a tread grooving device for all-steel radial tires. This invention can reduce the probability of device damage, improve the production efficiency of the device, and facilitate the adjustment of the cutting tool according to the tire, thereby improving the practicality and applicability of the device, 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:
[0006] A grooving device for all-steel radial tire treads includes a base, a support fixedly mounted on the top of the base, vertical plates fixedly mounted on the top of both sides of the base, a rotating shaft rotatably embedded on the front side of the support, a fixed seat fixedly connected to the front end of the rotating shaft, multiple support rods symmetrically and slidably mounted in a ring on the outer wall of the fixed seat, a fixed plate fixedly connected to each adjacent support rod, a horizontal bar slidably mounted between the vertical plates, multiple nuts fixedly and slidably mounted in an array within the horizontal bar, an adjusting screw threadedly mounted within each nut, the front end of each adjusting screw extending to the front side of the horizontal bar and rotatably connected to a mounting seat, a cutting tool slidably mounted through each mounting seat, and a clamping screw threadedly mounted on the front side of each mounting seat.
[0007] Furthermore, the fixed base has a plurality of sliding grooves arranged in a ring array. Each sliding groove is rotatably provided with a lead screw, and each lead screw is threaded with a slider. The end of the support rod away from the fixed plate extends into the adjacent sliding groove and is fixedly connected to the slider.
[0008] Furthermore, the fixed base has a cavity, and a motor is fixedly installed on the rear inner wall of the cavity. The output end of the motor is fixedly connected to a bevel gear. One end of the lead screw extends into the cavity and is fixedly connected to a bevel gear. The bevel gears mesh with the bevel gears.
[0009] Furthermore, a second motor is fixedly embedded in the support, and a rotating gear is fixedly provided on both the output end of the second motor and the rotating shaft, with the two rotating gears meshing with each other.
[0010] Furthermore, a second sliding groove is provided in the upper part of one of the vertical plates, and a third motor is fixedly provided on the inner wall of the bottom end of the second sliding groove. A second lead screw is fixedly connected to the output end of the third motor, and a second slider is threaded on the second lead screw. The second slider is fixedly connected to the side adjacent to the crossbar.
[0011] Furthermore, a groove three is provided in the upper part of another vertical plate, and a slider three is slidably disposed in the groove three. The slider three is fixedly connected to the side of the crossbar adjacent to it.
[0012] Furthermore, each of the mounting bases is fixedly provided with a sliding rod on its upper rear side, the rear end of each sliding rod extending through the crossbar to the rear side of the crossbar, and each sliding rod is provided with scale lines.
[0013] The beneficial effects of this utility model are:
[0014] This invention incorporates a first bevel gear, a second bevel gear, and multiple mounting seats. In use, the tire is fitted onto the mounting seats. A motor drives the first bevel gear to rotate, which in turn drives a lead screw to rotate. The lead screw then moves a slider, which, via a support rod, pushes a fixed plate outwards, bringing the fixed plate into contact with the inner wall of the tire and securing it. This reduces the number of drive components and lowers the probability of device damage. Simultaneously, rotating the adjusting screw causes the mounting seats to move back and forth via a nut, allowing adjustment of the mounting seats to the appropriate position and the individual cutters to the appropriate height. This enables simultaneous grooving of multiple grooves on the tire, improving the device's production efficiency. This invention reduces the probability of device damage, increases production efficiency, and facilitates cutter adjustment according to the tire, thus enhancing the device's practicality and applicability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:
[0024] A grooving device for all-steel radial tire treads includes a base 1, a support 2 fixedly mounted on the top of the base 1, vertical plates 3 fixedly mounted on the top of both sides of the base 1, a rotating shaft 4 rotatably embedded on the front side of the support 2, a fixed seat 5 fixedly connected to the front end of the rotating shaft 4, a plurality of support rods 6 symmetrically and slidably mounted in a ring on the outer wall of the fixed seat 5, a fixed plate 7 fixedly connected to each adjacent support rod 6, a horizontal bar 8 slidably mounted between the vertical plates 3, a plurality of nuts 9 fixedly and slidably mounted in an array within the horizontal bar 8, an adjusting screw 10 threadedly mounted within each nut 9, the front end of each adjusting screw 10 extending to the front side of the horizontal bar 8 and rotatably connected to a mounting seat 11, a cutting tool 12 slidably mounted through each mounting seat 11, and a clamping screw 13 threadedly mounted on the front side of each mounting seat 11.
[0025] Specifically, such as Figures 1-5 As shown, the fixed base 5 has multiple sliding grooves 14 arranged in a ring array. Each sliding groove 14 has a lead screw 15 rotatably mounted therein. Each lead screw 15 has a slider 16 threaded onto it. The end of the support rod 6 away from the fixed plate 7 extends into the adjacent sliding groove 14 and is fixedly connected to the slider 16. The fixed base 5 has a cavity, and a motor 17 is fixedly mounted on the rear inner wall of the cavity. The output end of the motor 17 is fixedly connected to a bevel gear 18. One end of each lead screw 15 extends into the cavity and is fixedly connected to a bevel gear 19. The bevel gear 19 meshes with the bevel gear 18. The motor 17 drives the bevel gear 18 to rotate, which in turn drives the lead screw 15 to rotate via the bevel gear 19. This causes the lead screw 15 to move the slider 16, which in turn pushes the fixed plate 7 outward via the support rod 6.
[0026] Specifically, such as Figures 1-5As shown, a second motor 20 is fixedly embedded in the support 2. A rotating gear 21 is fixedly provided on both the output end of the second motor 20 and the rotating shaft 4. The two rotating gears 21 mesh with each other. The second motor 20 drives the corresponding rotating gear 21 to rotate. At this time, the rotating gear 21 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the fixed seat 5 to rotate.
[0027] Specifically, such as Figures 1-5 As shown, one of the vertical plates 3 has a groove 22 in its upper part. A motor 23 is fixedly installed on the inner wall of the bottom end of the groove 22. A lead screw 24 is fixedly connected to the output end of the motor 23. A slider 25 is threaded onto the lead screw 24. The slider 25 is fixedly connected to the side adjacent to the crossbar 8. The other vertical plate 3 has a groove 26 in its upper part. A slider 27 slides in the groove 26. The slider 27 is fixedly connected to the side adjacent to the crossbar 8. The motor 23 drives the lead screw 24 to rotate, causing the lead screw 24 to move the slider 25 in the groove 22. The slider 25 can move the crossbar 8 up and down, so that the crossbar 8 can move the mounting base 11 and the cutter 12 to a suitable height through the adjusting screw 10. When the crossbar 8 moves, it will drive the slider 27 to move in the groove 26. The slider 27 can support the crossbar 8.
[0028] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that: each of the upper rear sides of the mounting base 11 is fixedly provided with a slide rod 28, the rear end of each slide rod 28 extends through the crossbar 8 to the rear side of the crossbar 8, and each slide rod 28 is provided with scale lines. When the mounting base 11 moves, the mounting base 11 will drive the slide rod 28 to move on the crossbar 8. The slide rod 28 can support the mounting base 11, and at the same time, the scale lines on the slide rod 28 make it easy to adjust the cutter 12 to a suitable position.
[0029] The working principle of this utility model is as follows: In use, the tire is fitted onto the fixed base 5. Motor 17 drives bevel gear 18 to rotate, which in turn drives lead screw 15 via bevel gear 19. Lead screw 15 then moves slider 16, which, via support rod 6, pushes fixed plate 7 outwards, causing it to contact the inner wall of the tire and thus securing it. Simultaneously, rotating adjusting screw 10, via nut 9, moves mounting base 11 back and forth, adjusting it to a suitable position. As mounting base 11 moves, it causes sliding rod 28 to move on crossbar 8. Sliding rod 28 supports mounting base 11, and the scale lines on sliding rod 28 facilitate adjustment of the cutter 12 to a suitable position. Each cutter 12 is moved to a suitable height, and then the clamping screw 13 is tightened to fix the cutter 12. At this time, the motor 20 drives the corresponding rotating gear 21 to rotate, which in turn drives the rotating shaft 4 to rotate, causing the fixed seat 5 to rotate, which in turn drives the tire to rotate. Then, the motor 3 23 drives the lead screw 24 to rotate, which in turn drives the slider 25 to move within the groove 22. The slider 25 drives the crossbar 8 to move downward, which in turn drives the mounting seat 11 and the cutter 12 to a suitable height via the adjusting screw 10. When the crossbar 8 moves, it drives the slider 3 27 to move within the groove 3 26. The slider 3 27 supports the crossbar 8, allowing the cutter 12 to contact the tire tread and perform grooving.
