Description

Technical Field

[0001] The utility model belongs to the field of tire mold detection, and in particular relates to a tire mold wire cutting detection device. Background Art

[0002] Before the entire tire mold tread ring is cut into multiple sector-shaped blocks using wire cutting equipment, it is necessary to mark the block positions on the upper end of the tread ring so that the wire cutting equipment can cut according to each marking position. Generally, 8-12 positions are marked. Because the inner surface of the tread ring has tread ribs of different shapes, in order to avoid cutting the ribs, each cutting position is precisely designed by technicians. In order to prevent the engraving machine from deviating when marking, it is necessary to check whether there is a hidden danger of cutting the ribs at the marking position after the marking on the upper end of the tread ring is completed.

[0003] At present, there are two commonly used detection methods by tire mold manufacturers: one is to use a template made of galvanized sheet to compare the marked position with the tread cavity surface. The disadvantage of this method is that the operating error is large. It is difficult to ensure that the template is perpendicular to the upper end face of the tread ring by hand. The template needs to avoid the tread ring before it can be lowered to the tread. In this way, there is no clear judgment on whether the tread ring is cut badly; the other is to make tooling and use the laser pen to swing up and down to detect whether the tread ring is cut badly (for details, please refer to Chinese invention patent 202010107333.X). The disadvantage is that the tooling cannot completely ensure that the laser pen passes through the center of the tread ring, and when the next dividing line is detected, it needs to be re-aligned, which will not only cause detection deviations, but also have low efficiency. Utility Model Content

[0004] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects, and advantages of the present application more readily apparent.

[0005] The utility model provides a tire mold wire cutting detection device, which greatly improves the detection accuracy and efficiency by quickly determining the rotation center of the laser pen and adopting axial upper and lower limit movement and circumferential 360° rotation.

[0006] The utility model discloses a tire mold wire cutting detection device, comprising:

[0007] Center seat;

[0008] A center column, vertically installed above the center seat;

[0009] A lifting seat moves up and down along the axial direction of the central column;

[0010] A laser pen is arranged in a horizontal direction and is rotatably mounted on the lifting seat through a rotating seat;

[0011] A plurality of positioning rods are arranged on the outer periphery of the center seat, and the outer end of each positioning rod is used to abut against the inner wall of the tire mold to be detected, so as to fix the rotation center position of the laser pen and make it coincide with the geometric center of the tire mold to be detected.

[0012] In some embodiments, the lifting seat is sleeved outside the central column, and a guide rail and a groove for sliding and locking connection are provided between the lifting seat and the central column.

[0013] In some embodiments, an annular groove is provided on the outer circumference of the lifting seat; the rotating seat sleeve is arranged on the annular groove; and the laser pen is connected to the outer wall of the rotating seat.

[0014] In some embodiments, the laser pen is threadedly connected to the outer wall of the rotating base.

[0015] In some embodiments, each of the positioning rods is composed of a plurality of connecting rods, a sleeve is provided on the outer sliding sleeve between adjacent connecting rods, and an adjusting bolt is provided between each connecting rod and the sleeve.

[0016] In some embodiments, a spherical protrusion is provided at the outer end of the positioning rod.

[0017] In some embodiments, the positioning rod is detachably connected to the central seat.

[0018] In some embodiments, the center column is located at the geometric center of the center seat, and the two are fixedly connected by mounting grooves and mounting bolts.

[0019] In some embodiments, there are three positioning rods, and the angle between adjacent positioning rods is 120°.

[0020] In some embodiments, the positioning rod and the sleeve are provided with scale marks on the outside.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] In view of the fact that the tangent line when cutting the tire mold tread ring is a vertical line structure, a lifting seat moving in the axial direction is used to ensure that when detecting the cutting line, as long as the laser is aligned with the current cutting line and then vertically lifted, the accuracy of the entire cutting line can be checked. At the same time, the cutting lines in different directions can be directly adjusted accordingly by rotation. Since the rotation center of the laser is always fixed by adjustment to coincide with the center of the tire mold tread ring to be detected, there is no need to make a secondary adjustment to the rotation center of the laser, which greatly improves the detection efficiency and accuracy.

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] Obviously, the drawings described below are only some examples or embodiments of the utility model. For ordinary technicians in this field, the utility model can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0030] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0031] A tire mold wire cutting detection device, comprising:

[0032] The center seat 1 may be a circular structure or a polygonal structure;

[0033] The center column 2 is vertically installed above the center seat 1, and can be a cylindrical structure as in this embodiment, or a rectangular parallelepiped structure;

[0034] The lifting seat 3 moves up and down along the axial direction of the central column 2;

[0035] The laser pen 6 is arranged in a horizontal direction and is rotatably mounted on the lifting base 3 through the rotating base 5;

[0036] A plurality of positioning rods 7 are arranged on the outer periphery of the center seat 1, and the outer end of each positioning rod 7 is used to abut against the inner wall of the tire mold to be detected, so as to fix the rotation center position of the laser pen 6 and make it coincide with the geometric center of the tire mold to be detected.

[0037] The laser pen 6 is rotated to adjust the emission position of its laser so as to align it with the cutting line to be detected, and then the height of the lifting seat 3 is adjusted to detect and judge the entire cutting line. The rotation center of the laser pen 6 is adjusted and fixed by multiple positioning rods 7 so that the rotation center of the laser pen 6 coincides with the geometric center of the tire mold to be detected. Therefore, when the next cutting line detection is performed, there is no need to repeatedly calibrate the center point, which greatly improves the detection efficiency.

[0038] In some embodiments, the lifting seat 3 is sleeved outside the central column 2, and a guide rail 4 and a groove connected by sliding engagement are provided between the lifting seat 3 and the central column 2. In this embodiment, since the central column 2 adopts a cylindrical structure design, in order to ensure that the laser pen 6 will not be deflected due to the rise and fall of the lifting seat 3 during lifting, a guide rail 4 with a convex structure is specifically provided on one side of the central column 2, and a corresponding groove is configured in the lifting seat 3 to achieve a guiding effect. If the central column 2 adopts a rectangular parallelepiped structure or a polygonal structure, there is no need to provide a corresponding guide rail 4 and a groove.

[0039] In some embodiments, an annular groove is provided on the outer periphery of the lifting seat 3; the rotating seat 5 is sleeved on the annular groove; and the laser pen 6 is connected to the outer wall of the rotating seat 5. The stability of the rotating seat 5 during rotation is ensured by the setting mode of the annular groove being embedded, and at the same time, a corresponding damping structure can be added between the annular groove and the rotating seat 5 to increase the friction coefficient therebetween, so as to prevent the laser pen 6 from deflecting due to interference during the inspection and maintenance process, resulting in inaccurate inspection. Similarly, a corresponding locking screw can also be added to achieve this.

[0040] In some embodiments, the laser pen 6 is threadedly connected to the outer wall of the rotating base 5 to facilitate installation and disassembly of the entire device.

[0041] In some embodiments, each positioning rod 7 is composed of a plurality of connecting rods, a sleeve 8 is provided on the outer sliding sleeve between adjacent connecting rods, and an adjusting bolt 9 is provided between each connecting rod and the sleeve 8 .

[0042] Since the sizes of different molds are different, such as 19 inches, 20 inches, 21 inches, etc., the length can be adjusted through the above structure, thereby increasing the application range of the equipment. During the adjustment process, the length change is controlled by pulling the corresponding connecting rod, and then the adjustment bolt 9 is used to lock and position.

[0043] In some embodiments, the outer end of the positioning rod 7 is provided with a spherical protrusion 12. The spherical protrusion 12 can reduce the collision with the inner wall while achieving positioning, and is also for the consideration that the inner wall of the tire mold is an arc-shaped structure.

[0044] In some embodiments, the positioning rod 7 is detachably connected to the center seat 1, such as by plugging, threading, etc.

[0045] In some embodiments, the center column 2 is located at the geometric center of the center seat 1, and the two are fixedly connected by means of the mounting groove 10 and the mounting bolt 11. The above-mentioned structural setting facilitates the adjustment and control of the length of the positioning rod 7, and it is only necessary to ensure that the length of each positioning rod 7 is equal to ensure that the rotation center of the laser pen 6 coincides with the geometric center of the tire mold to be detected.

[0046] In some embodiments, there are three positioning rods 7, and the angle between adjacent positioning rods 7 is 120°. The triangular structure supports stability and reliability, and is convenient and quick to adjust.

[0047] In some embodiments, the positioning rod 7 and the sleeve 8 are provided with scale marks on the outside to facilitate quick reading and determination of the overall length, so as to improve the work efficiency during adjustment and positioning.

[0048] Its working principle is:

[0049] Place the center seat 1 inside the tire mold to be tested, and then adjust the lengths of the three positioning rods 7. When the spherical protrusions 12 of the three positioning rods 7 are all in contact with the inside of the tire mold to be tested and have the same length, the calibration and positioning of the rotation center of the laser pen 6 are completed.

[0050] Turn on the laser pen 6 and adjust the rotation position of the rotating seat 5 so that the laser is irradiated onto the corresponding cutting line, and then quickly detect the entire cutting line by controlling the lifting and lowering of the lifting seat 3. After completion, adjust the position of the laser pen 6 again to detect the next cutting line.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
