Description

Technical Field

[0001] This utility model belongs to the technical field of precision milling fixtures for tire mold tread blocks, and specifically relates to a precision milling fixture suitable for different tread blocks. Background Technology

[0002] Tire mold tread blocks are key components used to shape the tread pattern on the tire surface during tire manufacturing. These patterns not only affect the tire's appearance but, more importantly, are related to key driving characteristics such as grip, water drainage, and noise control. Tread blocks come in various designs and are precision-machined using molds to ensure that each tire replicates the exact tread pattern. The production of tire mold tread blocks involves multiple processes. In the precision milling process, to facilitate the machining of the tire mold tread blocks, most manufacturers use precision milling fixtures to clamp them before performing precision milling with a milling cutter. However, most common precision milling fixtures cannot adjust the angle. During production, precision milling of different positions on the tire mold tread blocks requires frequent clamping and loosening, and multiple adjustments to achieve the final position. This leads to frequent adjustments by operators, hindering overall work efficiency and increasing the workload of the operators.

[0003] In summary, the precision milling fixture, which cannot easily adjust the angle of the tread blocks in the tire mold, has some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a precision milling fixture suitable for different patterned blocks, and to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a precision milling fixture suitable for different pattern blocks, comprising: a fixture body, a left-end clamping mechanism, and a right-end clamping assembly. The fixture body has a base at its lower end. The upper surface of the base has vertical plates on both the left and right ends for mounting the left-end clamping mechanism and the right-end clamping assembly. The right side of the left vertical plate has a left-end clamping mechanism for clamping tire mold pattern blocks, and the left side of the right vertical plate has a right-end clamping assembly for clamping tire mold pattern blocks. The left-end clamping mechanism consists of the right-end left-end clamping assembly and the left-end angle adjustment assembly.

[0006] In a preferred embodiment, the left-end clamping assembly and the right-end clamping assembly have a rotating shaft at the end away from the center of the tooling body, and a clamping seat at the end of the rotating shaft near the center of the tooling body.

[0007] In a preferred embodiment, the clamping seat is provided with a clamping cylinder at one end near the center of the tooling body for moving the clamping plate, and the clamping cylinder is provided with a clamping plate at one end near the center of the tooling body for clamping the tire mold tread block. The clamping cylinder can move the clamping plate so that the two sets of clamping plates clamp and fix the tire mold tread block.

[0008] In a preferred embodiment, the angle adjustment assembly has an adjustment plate at its upper end, two sets of spaced rotating seats on the left rear side of the adjustment plate, and a rotating block between the two sets of rotating seats.

[0009] In a preferred embodiment, an adjusting rod is provided below the rotating block, an adjusting threaded hole is provided on the lower surface of the adjusting rod, an adjusting stud is provided inside the adjusting threaded hole, and the adjusting stud is threadedly connected to the adjusting threaded hole;

[0010] The lower end of the adjusting stud is provided with a bearing, and an adjusting seat is provided on the outside of the bearing. Above the adjusting seat and on the outside of the adjusting stud, there is a fixing tooth for assisted angle fixing of the adjusting stud. Rotating the adjusting stud to make it rotate inside the adjusting thread hole allows the adjusting plate to rotate when the rotating block is connected to the rotating seat, thereby achieving the effect of angle adjustment.

[0011] In a preferred embodiment, the lower left rear side of the left end of the upright plate is provided with a fixing plate for fixing the left end clamping mechanism, and a fixing seat is provided above the fixing plate, with an inner cavity opened on the right side of the inner side of the fixing seat.

[0012] In a preferred embodiment, a fixing spring is provided on the inner side of the cavity, a push plate is provided on the left side of the fixing spring, a fixing post is provided on the left side of the push plate, and a fixing block is provided on the left side of the fixing post. The fixing block engages with the outer side of the fixing tooth.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By adding the main body of the tooling, the left-end clamping mechanism and the right-end clamping assembly, the tire mold tread block is placed between the left-end clamping plate and the right-end clamping plate. Activating the two sets of clamping cylinders can clamp and fix the tire mold tread block. Rotating the adjusting stud makes it rotate inside the adjusting thread hole. The connection between the rotating block and the rotating seat can drive the adjusting plate to rotate, so that the left-end clamping assembly can rotate around the rotating shaft, thereby achieving the effect of convenient angle adjustment. By adding the main body of the tooling and the left-end clamping mechanism, when angle adjustment is required, the fixing column is pressed to the right to compress the fixing spring. After the angle adjustment is completed, the external force is removed so that the fixing block and the outer side of the fixing tooth can be engaged, which can assist in fixing the adjusting stud.

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.

[0026] Please see Figures 1 to 6 The present invention provides a technical solution: a precision milling fixture suitable for different patterned blocks, comprising: a fixture body 100, a left-end clamping mechanism 200 and a right-end clamping assembly 300, wherein the lower end of the fixture body 100 is provided with a base 101.

[0027] The upper surface of the base 101 is provided with upright plates 102 at both the left and right ends for mounting the left end clamping mechanism 200 and the right end clamping assembly 300. The left end upright plate 102 is provided with a left end clamping mechanism 200 for clamping the tire mold pattern block on the right side.

[0028] The right end plate 102 has a right end clamping component 300 for clamping the tire mold pattern block on the left side. The left end clamping mechanism 200 is composed of the right end left end clamping component 201 and the left end angle adjustment component 202.

[0029] The left clamping assembly 201 and the right clamping assembly 300 have a rotating shaft 201a at the end away from the center of the tooling body 100, and a clamping seat 201b at the end of the rotating shaft 201a near the center of the tooling body 100.

[0030] The clamping base 201b is provided with a clamping cylinder 201c at one end near the center of the tooling body 100 for moving the clamping plate 201d. The clamping cylinder 201c is provided with a clamping plate 201d at one end near the center of the tooling body 100 for clamping the tire mold tread block. The clamping cylinder 201c can drive the clamping plate 201d to move, so that the two sets of clamping plates 201d clamp and fix the tire mold tread block.

[0031] The angle adjustment assembly 202 has an adjustment plate 202a at its upper end, two sets of spaced rotating seats 202b on the left rear side of the adjustment plate 202a, and a rotating block 202c between the two sets of rotating seats 202b.

[0032] Below the rotating block 202c, there is an adjusting rod 202d. An adjusting threaded hole is opened on the lower surface of the adjusting rod 202d. An adjusting stud 202e is provided inside the adjusting threaded hole. The adjusting stud 202e is threadedly connected to the adjusting threaded hole.

[0033] A bearing is provided on the outer side of the lower end of the adjusting stud 202e, and an adjusting seat 202g is provided on the outer side of the bearing.

Rotating the adjusting stud 202e to make it rotate inside the adjusting thread hole allows the adjusting plate 202a to rotate when the rotating block 202c is connected to the rotating seat 202b, thereby achieving the effect of angle adjustment.

[0034] Please see Figures 1-2 and Figures 4-6 As the first embodiment of this utility model: First, the operator places the tire mold tread block between the left end clamping plate 201d and the right end clamping plate 201d. Activating the two sets of clamping cylinders 201c can clamp and fix the tire mold tread block. Second, according to the milling position requirements, the operator rotates the adjusting stud 202e to rotate inside the adjusting threaded hole, changing the extension length of the adjusting stud 202e. This allows the adjusting plate 202a to rotate through the connection between the rotating block 202c and the rotating seat 202b, causing the left end clamping assembly 201 to rotate around the rotating shaft 201a, thereby achieving the effect of convenient angle adjustment.

After the angle adjustment is completed, the external force is removed so that the fixing block 108 engages with the outer side of the fixing tooth 202f, which can assist in the fixing of the adjusting stud.

[0037] Please see Figures 1-4 and Figure 6 As a second embodiment of this utility model: Based on the first embodiment above, before the tire mold tread block needs to be adjusted in angle, the operator presses the fixing post 106 to the right to compress the fixing spring 107, so that the fixing block 108 disengages from the outer side of the fixing tooth 202f. After the angle adjustment is completed, the external force is removed, and the rebound force of the fixing spring 107 drives the fixing block 108 to engage with the outer side of the fixing tooth 202f, thereby assisting in the adjustment of the stud fixing.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
