Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire processing equipment technology, and in particular to a tire tread engraving stand. Background Technology
[0002] Tire tread engraving is a crucial step in the tire manufacturing or retreading process, aiming to enhance tire performance through carefully designed patterns. These patterns not only increase the friction between the tire tread and the road surface, effectively preventing wheel slippage, but also further enhance the frictional contact between the tire and the road surface through the elastic deformation of the tread blocks under tangential forces such as driving force, braking force, and lateral force. Furthermore, the clever layout of the tire tread also helps with water drainage, significantly improving tire grip on wet and slippery roads and ensuring driving safety.
[0003] In response to the need for tire tread engraving, patent publication number CN218018817U discloses a tire tread engraving stand, which solves the technical problem that existing tire tread engraving stands require matching rims or other auxiliary tools to fix the engraved tires. It has the feature of being able to quickly fix all types of passenger car tires.
[0004] However, in practical applications, this platform still has limitations: it only clamps the tire in the vertical direction and lacks horizontal stabilization measures, making the tire susceptible to slippage due to external forces during the carving process, thus affecting processing accuracy. Furthermore, the height of its fixing components remains constant, requiring operators to lift and move the tire onto the unidirectional rotating shaft during installation—a time-consuming and labor-intensive process. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the present invention provides a tire pattern engraving stand.
[0006] The technical implementation scheme of this utility model is as follows: a tire tread engraving frame includes a base plate, columns, U-shaped mounting brackets, a fixed plate, a hydraulic cylinder, a rotating component, a vertical clamping component, and a horizontal clamping component. Two columns are fixedly connected at intervals on the left and right sides of the top of the base plate. U-shaped mounting brackets are slidably connected between the two columns on the left and the two columns on the right. Fixed plates are fixedly connected between the upper and middle parts of the two U-shaped mounting brackets. A hydraulic cylinder is installed in the middle of the top of the base plate. The piston rod of the hydraulic cylinder is fixedly connected to the fixed plate in the middle of the U-shaped bracket. A rotating component is provided between the front sides of the two U-shaped mounting brackets. A vertical clamping component for vertically clamping the tire is provided on the rotating component. The rotating component is used to drive the vertical clamping component to rotate. A horizontal clamping component for horizontally clamping the tire is provided on the vertical clamping component.
[0007] To further explain, the rotating assembly includes a mounting ring, a turntable, a gear ring, a stepper motor, and a spur gear.

The output shaft end of the stepper motor is fixedly connected to a spur gear, which meshes with the gear ring.
[0008] To further explain, the vertical clamping assembly includes a mounting frame, lead screw a, bevel gear a, servo motor, bevel gear b, and L-shaped clamping plate. Three mounting frames are fixedly connected to the front side of the turntable at even intervals along the circumference. Lead screw a is rotatably connected to each of the three mounting frames. Bevel gear a is fixedly connected to the ends of the three lead screws a that are close to each other. A servo motor is mounted on the rear side of the turntable. The output shaft of the servo motor passes through the turntable, and bevel gear b is fixedly connected to its end. All three bevel gears a mesh with bevel gear b. L-shaped clamping plates are slidably arranged in each of the three mounting frames. The three lead screws a pass through adjacent L-shaped clamping plates and are threaded together.
[0009] To further explain, the transverse clamping assembly includes a fixed base, a geared motor, a lead screw b, and clamping plates. Two fixed bases are fixedly connected to each of the three L-shaped clamping plates at intervals. A lead screw b is rotatably connected between the two fixed bases on the same L-shaped clamping plate. A geared motor is installed on each of the three L-shaped clamping plates. The output shaft end of each geared motor is fixedly connected to the rear end of the adjacent lead screw b. Two clamping plates are slidably connected to each of the three L-shaped clamping plates at intervals. The three lead screws b pass through the adjacent clamping plates and are threaded into them.
[0010] To further explain, it also includes reinforcing plates, with two reinforcing plates fixedly connected at intervals to each of the three L-shaped plates.
[0011] To further explain, it also includes a protective shell, which is fixedly connected to the middle of the front side of the turntable.
[0012] The beneficial effects of this utility model are as follows: Through the coordinated work of servo motor, geared motor and stepper motor, this utility model realizes the stable clamping and multi-position engraving of tires of different models. At the same time, the adjustment function of hydraulic cylinder makes the height of U-shaped mounting bracket adjustable, which can adapt to different sizes without moving the tire, greatly improving work efficiency and operation convenience, and ensuring the stability and safety of the processing process.

Detailed Implementation
[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0019] Example: A tire tread pattern engraving stand, such as Figures 1-4 As shown, the device includes a base plate 1, uprights 2, a U-shaped mounting bracket 21, a fixing plate 22, a hydraulic cylinder 23, a rotating assembly, a vertical clamping assembly, and a horizontal clamping assembly. Two uprights 2 are welded and fixed to the top left and right sides of the base plate 1 at intervals. The U-shaped mounting brackets 21 are slidably connected between the two uprights 2 on the left and the two uprights 2 on the right. The fixing plate 22 is welded and fixed between the upper and middle parts of the two U-shaped mounting brackets 21. A hydraulic cylinder 23 is bolted to the top center of the base plate 1. The piston rod of the hydraulic cylinder 23 is fixedly connected to the fixing plate 22 in the middle of the U-shaped bracket. A rotating assembly is provided between the front sides of the two U-shaped mounting brackets 21. The rotating assembly has a vertical clamping assembly for vertically clamping the tire and drives the vertical clamping assembly to rotate. The vertical clamping assembly has a horizontal clamping assembly for horizontally clamping the tire.
[0020] like Figure 1 , Figure 2 and Figure 3As shown, the rotating assembly includes a mounting ring 31, a turntable 32, a gear ring 33, a stepper motor 34, and a spur gear 35. The mounting ring 31 is fixed between the front sides of the two U-shaped mounting brackets 21 by bolts. The turntable 32 is rotatably connected to the middle of the mounting ring 31. The gear ring 33 is fixed to the rear side of the turntable 32 by bolts. The stepper motor 34 is mounted on the lower side of the fixing plate 22 on the upper part of the U-shaped mounting bracket 21 by bolts. The spur gear 35 is fixedly connected to the output shaft end of the stepper motor 34, and the spur gear 35 meshes with the gear ring 33.
[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the vertical clamping assembly includes a mounting frame 41, a lead screw a42, a bevel gear a43, a servo motor 44, a bevel gear b45, and an L-shaped clamping plate 46. Three mounting frames 41 are welded and fixed to the front side of the turntable 32 at even intervals along the circumference. The lead screw a42 is rotatably connected to each of the three mounting frames 41. The bevel gear a43 is fixedly connected to the close ends of the three lead screws a42. The servo motor 44 is bolted to the rear side of the turntable 32. The output shaft of the servo motor 44 passes through the turntable 32, and the bevel gear b45 is fixedly connected to its end. The three bevel gears a43 mesh with the bevel gear b45. The L-shaped clamping plate 46 is slidably arranged in each of the three mounting frames 41. The three lead screws a42 pass through adjacent L-shaped clamping plates 46 and are threaded together.
[0022] like Figure 4 As shown, the transverse clamping assembly includes a fixed base 51, a reduction motor 52, a lead screw b53, and clamping plates 54. Two fixed bases 51 are welded and fixed to each of the three L-shaped clamping plates 46 at intervals. The lead screw b53 is rotatably connected between the two fixed bases 51 located on the same L-shaped clamping plate 46. The reduction motor 52 is bolted to each of the three L-shaped clamping plates 46. The output shaft end of each reduction motor 52 is fixedly connected to the rear end of the adjacent lead screw b53. Two clamping plates 54 are slidably connected to each of the three L-shaped clamping plates 46 at intervals. The three lead screws b53 pass through the adjacent clamping plates 54 and are threaded to them. The lead screw b53 is a bidirectional lead screw. When the lead screw b53 rotates, it can drive the two adjacent clamping plates 54 to move closer or further apart.
[0023] First, the worker rolls the tire to be processed to the front of the three L-shaped clamps 46, then pushes the tire backward so that it fits onto the three L-shaped clamps 46 and is positioned between the two clamping plates 54 on the same L-shaped clamp 46. Next, the servo motor 44 is started, driving the bevel gear b45 to rotate. Through the meshing of the three bevel gears a43 and the bevel gear b45, the three lead screws a42 are driven to rotate, thereby pushing the three L-shaped clamps 46 outward along the adjacent mounting frames 41 to clamp and fix the middle of the tire. This meets the fixing requirements of different tire models. Subsequently, the worker simultaneously starts the three reduction motors 52, which drive the three adjacent lead screws b53 to rotate, thereby pushing the two adjacent... The clamping plates 54 move closer to each other to clamp and fix the front and rear sides of the tire. This ensures that the tire will not slip horizontally during processing. After the tire is fixed, engraving can be performed. At the same time, by starting the stepper motor 34, the stepper motor 34 drives the turntable 32 to rotate through the meshing of the spur gear 35 and the gear ring 33, which allows for engraving at different positions on the tire. When processing other tire models (larger or smaller), the operator can start the hydraulic cylinder 23 to control the extension or retraction of the piston rod of the hydraulic cylinder 23 to adjust the height of the U-shaped mounting bracket 21. This allows the three L-shaped clamping plates 46 to be positioned in the middle of different tire models, eliminating the need to lift the tire and place it on the L-shaped clamping plates 46, thus saving time and effort.
[0024] like Figure 4 As shown, it also includes reinforcing plates 6, with two reinforcing plates 6 welded and fixed at intervals on each of the three L-shaped plates.
[0025] By setting the reinforcing plate 6, the structural strength of the L-shaped clamp 46 is further enhanced, ensuring the stability of the L-shaped clamp 46 when clamping the tire.
[0026] like Figure 4 As shown, it also includes a protective shell 7, which is fixed to the center of the front side of the turntable 32 by bolts.
[0027] By providing the protective shell 7, the bevel gears a43 and b45 can be effectively protected, preventing them from being damaged by external factors.
[0028] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
