Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, specifically a tire mold tread block fitting and finishing platform. Background Technology

[0002] In the process of trimming the tread blocks of tire molds, effective clamping of the tread blocks is a key prerequisite for ensuring trimming accuracy and operational safety. However, the clamping method used by traditional trimming platforms has significant defects, and its core problem lies in the limitations of the clamping and fixing mode.

[0003] Traditional platforms generally employ a simple double-sided clamping structure, using mechanical force to apply pressure from both sides of the pattern block for fixation. While this clamping method seems direct, the clamping force can only act on a limited number of flat sides when clamped on both sides. This not only fails to cover the overall outline of the pattern block but also easily leads to a shift in the clamping center of gravity due to the single point of force application. When workers perform filing, grinding, or other force-applying operations, the pattern block is prone to slight slippage along the clamping direction, or even localized vibrations, severely affecting the precise fit between the finishing tool and the pattern block surface. Furthermore, the fixed height of the mold finishing workbench makes it difficult for workers of different heights to operate, resulting in significant strain on their lower backs and increasing the risk of occupational diseases. Moreover, the platform is usually fixed, preventing mold rotation. After finishing a certain area, workers need to use handling tools to rotate the pattern block at a certain angle before finishing other areas, which is time-consuming, labor-intensive, and reduces production efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tire mold tread block fitter's trimming platform, including an operating table, on which a multi-directional adjustment mechanism is installed, an upper plate is fixed at the top of the multi-directional adjustment mechanism, and a clamping mechanism is installed at the top of the upper plate. The clamping mechanism includes a main clamping component for applying clamping force to both sides of the workpiece, and an auxiliary clamping component for providing auxiliary support to the workpiece's arc surface.

[0005] Furthermore, the auxiliary clamping assembly includes a recessed block, on which two sets of connecting rod structures are mounted, and a push top on both sides that pushes the two sets of connecting rod structures to clamp.

[0006] Furthermore, the linkage structure includes several linkages and several connecting plates. Fixed shafts and positioning shafts are respectively installed at both ends of the concave block. The positioning shafts are linked with the linkages through the connecting plates. Multiple sets of pulleys rotate at both ends of the linkages. The two outermost sets of linkages are rotatably connected to two sets of arc-shaped plates with their corresponding fixed shafts. A concave plate adapted to the arc-shaped plate rotates on the positioning shaft.

[0007] Furthermore, the push top includes a second bidirectional threaded screw that is laterally rotatably connected to the upper plate and passes through the concave block. The threaded section of the second bidirectional threaded screw is threadedly connected to a movable block that slides with the upper plate. A rotating shaft is fixed on the movable block, and bearings located below the corresponding arc plate are installed at both ends of the rotating shaft.

[0008] Furthermore, the main clamping assembly includes a first bidirectional threaded screw that is rotatably connected to the upper plate and passes through the concave surface of the recessed block. The threaded end of the first bidirectional threaded screw is threadedly connected to a counter clamping plate that slides with the upper plate. A support block that slides with the upper plate is formed on the opposite side of the counter clamping plate.

[0009] Furthermore, the multi-directional adjustment mechanism includes a height adjustment component, a tilt adjustment component, and a rotation adjustment component.

[0010] Furthermore, the height adjustment assembly includes a frame plate slidably connected to the operating table, a screw jack is mounted on the frame plate, and a guide sleeve adapted to the screw of the screw jack is mounted on the operating table.

[0011] Furthermore, the tilt adjustment assembly includes a pair of upper plates fixed to the top of the frame plate, and a pair of upper lifting cylinders hinged to the inner side. A lower plate is hinged between the upper plates, and the piston rod of the upper lifting cylinder is hinged to the bottom of the lower plate.

[0012] Furthermore, the rotation adjustment assembly includes a drive motor mounted on the bottom of the lower plate and driving the upper plate to rotate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The clamping mechanism adopts a collaborative working mode of main clamping component and auxiliary clamping component. The main clamping component provides symmetrical clamping force from the side, while the auxiliary support unit provides adaptive support for complex structures such as curved and irregular surfaces of the pattern block, forming a multi-point, all-round stable clamping. This effectively solves the problems of single force and easy slippage in traditional clamping methods. It can adapt to the clamping needs of pattern blocks of different specifications and structures, and significantly improves the stability and accuracy of the finishing operation.

[0015] 2. The multi-directional adjustment mechanism can adjust the height, rotation and tilt, which can adapt to the working posture of operators of different heights, avoid operators being in poor posture for a long time, reduce the risk of occupational diseases, and improve the comfort and safety of operation. At the same time, it can switch and trim different areas of the pattern block without manual handling, which greatly saves the workpiece flipping time and labor costs, while avoiding positioning deviations during the handling process and ensuring the continuity and accuracy of trimming.

[0021] 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.

[0022] Please see Figure 1-4 This embodiment of a tire mold tread block fitter's trimming platform includes an operating table 1. A multi-directional adjustment mechanism is installed on the operating table 1 to realize the height, tilt and rotation adjustment of the platform. An upper plate 8 is fixed to the rotating end of the multi-directional adjustment mechanism, and the upper plate 8 provides a mounting carrier for the clamping mechanism. A clamping mechanism is installed on the top of the upper plate 8. The clamping mechanism is divided into a main clamping component for applying clamping force to both sides of the workpiece and an auxiliary clamping component for auxiliary support of the workpiece's arc surface, for stabilizing the clamping of the tire mold tread block. A control box is also installed on the operating table 1.

[0023] like Figure 2 The multi-directional adjustment mechanism includes a height adjustment component, a tilt adjustment component, and a rotation adjustment component.

[0024] The height adjustment assembly includes a frame plate 2 that is slidably connected to the side wall of the operating platform 1. A screw jack 4 is installed on the top of the protruding end of the frame plate 2. A guide sleeve 3 is installed on the bottom of the operating platform 1. The screw of the screw jack 4 is threadedly connected in the guide sleeve 3. When the screw jack 4 on the frame plate 2 is working, its screw moves up and down along the guide sleeve 3 on the operating platform 1, thereby driving the frame plate 2 and the structure above it to move up and down as a whole, so as to adjust the height of the platform to suit the working needs of operators of different heights.

[0025] The tilt adjustment assembly includes two sets of upper plates 24 fixed to the top of the frame plate 2. A lower plate 6 is hinged between the upper plates 24. A pair of upper cylinders 5 are hinged to the side wall of the frame plate 2. The piston rod of the upper cylinder 5 is hinged to the bottom of the lower plate 6. The lower plate 6 is hinged between the upper plates 24. When the piston rod of the upper cylinder 5 hinged on the inner side extends or retracts, it can push the lower plate 6 to rotate around the hinge point with the upper plate 24, thereby realizing the tilt angle adjustment of the upper plate 8 and the workpiece, which is convenient for the operator to adjust the different tilt surfaces of the workpiece.

[0026] The rotary adjustment assembly includes an upper plate 8 rotatably connected to the lower plate 6. A drive motor 7 is installed at the bottom of the lower plate 6 to drive the upper plate 8 to rotate. When the drive motor is running, it can directly drive the upper plate 8 to rotate, thereby driving the clamped pattern block to rotate. The workpiece can be switched and trimmed in different areas without manual handling, saving time and manpower. The two sets of buttons on the control box control the screw jack 4 and the drive motor 7 respectively.

[0027] like Figure 4The auxiliary clamping assembly includes a recessed block 16 fixed at the center of the upper plate 8, and a pusher top that passes through the recessed block 16. Both protruding ends of the recessed block 16 are equipped with connecting rod structures. The pusher top is used to drive the connecting rod structures to provide auxiliary support for the workpiece's curved surface. The connecting rod structure includes a fixed shaft 21 and a positioning shaft 17 respectively fixed to the two protruding ends of the recessed block 16. The positioning shaft 17 is linked to multiple connecting rods 23 via multiple sets of connecting plates 19. Two sets of curved plates 20 are rotatably mounted on the leftmost and rightmost connecting rods 23 and their corresponding fixed shafts 21. Both ends of the connecting rods 23 are rotatably mounted with pulleys 18, which reduce friction with the workpiece. The positioning shaft 17 is also rotatably mounted with one end of the curved plate 20 facing inwards. The concave plate 22 is equipped with a second bidirectional threaded screw 12 that passes through the concave block 16 and is laterally rotatably connected to the upper plate 8. The threaded section of the second bidirectional threaded screw 12 is threadedly connected to a movable block 13 that slides with the upper plate 8. A rotating shaft 14 is fixed on the movable block 13, and bearings 15 are fixed at both ends of the rotating shaft 14. The rotation of the second bidirectional threaded screw drives the movable block to move along the upper plate, which in turn drives the bearings 15 to push the corresponding arc plate 20 to rotate. The arc plate 20 is rotatably connected to the fixed shaft 21 and is linked with the positioning shaft 17 through the connecting rod 23 and the connecting plate 19, forming a multi-point auxiliary support for the workpiece arc surface. Together with the main clamping assembly, it achieves all-round stable clamping of the workpiece and avoids slippage or vibration during the trimming process.

[0028] like Figure 3 The main clamping assembly includes a first bidirectional threaded screw 9 that is rotatably connected to the upper plate 8 and passes through the concave surface of the recessed block 16. When the first bidirectional threaded screw 9 is rotated, its threaded end is threadedly connected to a clamping plate 10. The clamping plate 10 slides along the upper plate 8. A support block 11 is formed on the opposite side of the clamping plate 10 and slides synchronously on the upper plate 8. The opposite side of the clamping plate 10 is also textured. Symmetrical clamping forces are applied from both sides of the workpiece. With the support of the support block and the texture, the workpiece is stably fixed.

[0029] The working principle of the above embodiments is as follows:

[0030] After placing the tire mold tread block between the connecting rod structures, the initial positioning is achieved by adapting the size of the tire mold tread block through the linkage of the connecting rod and the connecting plate. The second bidirectional threaded screw, laterally connected to the upper plate, is rotated. When the second bidirectional threaded screw rotates, the moving block connected to its threaded section slides along the upper plate, causing the bearings at both ends of the rotating shaft on the moving block to move synchronously. The bearings push the arc-shaped plates on both sides to rotate around the fixed axis. The arc-shaped plates, through the connecting plate, drive multiple sets of connecting rods on the positioning shaft. The pulleys at both ends of the connecting rods reduce friction with the workpiece, while the concave plate adapts to the rotating rail on the inner end of the arc-shaped plate. Ultimately, the arc-shaped plate, through its linkage with the connecting rod structure, forms multi-point support for the workpiece's arc surface. Then, in conjunction with the main clamping assembly, the first bidirectional threaded screw, which passes longitudinally through the concave surface of the concave block, rotates. When the first bidirectional threaded screw rotates, the two sets of clamping plates connected to its threaded end slide along the upper plate and move closer to each other. The support blocks on opposite sides of the clamping plates move synchronously, while simultaneously applying symmetrical clamping forces to the clamping plates from both sides of the workpiece. The texture on the inner side of the clamping plates increases the friction with the workpiece, and in conjunction with the supporting action of the support blocks, achieves stable fixation of both sides of the workpiece, realizing omnidirectional stable clamping of the workpiece.

[0031] According to their own height requirements, the operator starts the screw jack on the platform. When the screw jack is working, its screw moves up and down along the guide sleeve at the bottom of the operating platform, which in turn drives the platform and the tilt adjustment component, rotation adjustment component and clamping mechanism above it to move up and down as a whole until the platform height is suitable for the operator's work, thus achieving precise height adjustment.

[0032] When different inclined surfaces of the workpiece need to be adjusted, the upper cylinder hinged to the side wall of the control plate is activated. When the piston rod of the upper cylinder extends or retracts, it pushes the lower plate to rotate around the hinge point with the upper plate. The two sets of upper plates are fixed on the top of the control plate, providing a hinge fulcrum for the lower plate. The rotation of the lower plate drives the upper rotary adjustment component, the upper plate and the clamped workpiece to tilt synchronously, thereby realizing the adjustment of the workpiece tilt angle, which makes it easier for operators to handle the inclined surface of the workpiece.

[0033] When it is necessary to switch between different areas of the workpiece during the trimming process, the drive motor at the bottom of the lower platen is started. When the drive motor is running, it directly drives the upper platen connected to it to rotate. The upper platen drives the patterned block held at the top to rotate synchronously. The switching between different trimming areas of the workpiece can be completed without manual handling, saving manpower and time.
