[0029] Figure 1 This is a three-dimensional diagram of a melon slice support according to an embodiment of the present invention; Figure 2 This is a top view of a melon slice support according to an embodiment of the present invention; Figure 3 It is a schematic diagram of a push-pull clamp according to an embodiment of the present invention.

[0030] like Figure 1 and 2 As shown, the utility model provides a melon slice bracket, comprising: a high bracket and a low bracket, the high bracket is used to support the inner side surface of the upper end of the melon slice workpiece, and the low bracket is used to support the lower end of the melon slice workpiece.

[0031] Unlike traditional molds that use a monolithic surface to support the melon slice workpiece, the melon slice support in this embodiment utilizes a high bracket and a low bracket that, in conjunction with the mold, support the processed melon slice workpiece. This allows for welding and supporting the melon slice ring, reducing tooling costs. The high bracket and low bracket can be relatively independent brackets, or they can be welded or assembled into a single structure.

[0032] According to one embodiment of the present invention, the elevated support comprises an elevated base 10 and a roller 1, which is rotatably disposed on the top of the elevated base 10. The roller 1 is used to support the upper end surface of the melon slice workpiece and rotate along the circumferential direction of the melon slice support by rotating the melon slice workpiece.

[0033] In this embodiment, the elevated base can be provided with a high-profile steel frame 2, with rollers rotatably mounted on the top of the high-profile steel frame. The high-profile steel frame and the elevated base can be integrally formed or removably connected, and the elevated base can be fixedly connected to ground connection holes or bolts. The melon slice support can rotate on the melon slice support by rotating the rollers, thereby coordinating the melon slice workpiece.

[0034] According to one embodiment of the present invention, the low support includes a low support base 9 and a roller wheel 7, which is rotatably arranged on the top of the low support base 9. The roller wheel 7 is used to support the lower end surface of the melon slice workpiece and rotates to cooperate with the melon slice workpiece to rotate along the circumferential direction of the melon slice support.

[0035] In this embodiment, the low-profile base can be provided with a low-profile steel frame 8, and the roller wheel can be mounted on top of the low-profile steel frame. The low-profile steel frame and the elevated base can be integrally formed or removably connected, and the elevated base can be fixedly connected to a connection hole or bolts on the ground. The melon slice support can assist the melon slice workpiece in rotating on the melon slice support through the rotation of the roller wheel. For example, the roller wheel can be a steel roller.

[0036] Different from the traditional mold that uses a fixed method to support the melon slice workpiece, the melon slice bracket of the utility model uses multiple sets of rollers and roller wheels for the support and contact parts of the melon slice workpiece, making the movement of the melon slice workpiece on the melon slice bracket more convenient, and does not require multiple people to carry it or use a crane to lift it.

[0037] According to one embodiment of the present invention, the melon segment support is a circular ring support, a circumference tire 5 is provided at the top of the low support, and the inner side surface of the melon segment workpiece is placed in contact with the circumference tire 5 .

[0038] The melon slice support of this embodiment can be a non-circular ring structure, with a single melon slice mold placed in the gap to form a full-circular structure to support and weld the melon slice workpiece to the tank bottom. After the melon slice workpiece is welded on the mold, it can be transferred to the melon slice support. The melon slice support uses the perimeter mold as the reference for the lower end profile and perimeter of the melon slice workpiece, which can achieve control of the total perimeter of the melon slice ring formed by welding the melon slice workpiece. The perimeter mold can be a whole or include multiple arc segments distributed along the melon slice support.

[0039] According to one embodiment of the present invention, the perimeter tire 5 is provided with a plurality of oblong holes 6 along its circumference, and the oblong holes 6 are used to align with the pin holes of the melon slice workpiece to position the melon slice workpiece.

[0040] In this embodiment, the oblong holes 6 can be connected to the pin holes on the melon slice workpiece using pins to limit the height of the melon slice workpiece on the melon slice support. For example, the connection can be made by manually inserting the pins. The oblong holes 6 can be evenly distributed along the circumference of the tire.

[0041] According to one embodiment of the present invention, a plurality of retractable pins are provided along the circumference of the circumferential tire 5 , and the retractable pins are used to cooperate with the pin holes of the melon slice workpiece to position the melon slice workpiece.

[0042] In this embodiment, the retractable pins can be pneumatic or electric retractable pins, which improve the degree of automation of the melon slice stand.

[0043] According to one embodiment of the present invention, an arc-segment pressing device is further provided at the top of the low support, comprising a push-pull fixture 3 and an arc-shaped pressing block 4. The push-pull fixture 3 is fixedly connected to the arc-shaped pressing block 4 and is used to push the arc-shaped pressing block 4 toward the melon slice workpiece to press the melon slice workpiece against the circumference tire 5, or to pull the arc-shaped pressing block 4 away from the melon slice workpiece.

[0044] In this embodiment, the circumference tire can be set at the part of the top of the low-profile steel frame close to the inner side surface, and the push-pull clamp moves radially inward along the melon slice support toward the melon slice workpiece, pressing the inner side surface of the melon slice workpiece to the circumference tire. Alternatively, the circumference tire can be set at the part of the top of the low-profile steel frame close to the outer side surface, and the push-pull clamp moves radially outward along the melon slice support toward the melon slice workpiece, pressing the outer side surface of the melon slice workpiece to the circumference tire. The push-pull clamp can be a manual push-pull clamp, which forms a manual pressing device with the arc-shaped pressure block. The melon slice support presses the melon slice workpiece onto the circumference tire through the arc-segment pressing device, and the melon slice ring can be radially positioned with the circumference tire as a reference to ensure the consistency of the total circumference of the melon slice ring formed by welding the melon slice workpieces.

[0045] Before using the arc segment pressing device to press the melon slice workpiece, the oblong hole can be connected to the pin hole on the melon slice workpiece using a pin to prevent the height of the melon slice workpiece from moving during the pressing process of the melon slice workpiece.

[0046] According to one embodiment of the present invention, the push-pull clamp 3 includes an arc-segment drive cylinder. One end of the arc-segment drive cylinder is connected to the low bracket, and the other end is connected to the arc-shaped pressing block 4 to push or pull the arc-shaped pressing block 4.

[0047] In this embodiment, the arc segment driving cylinder can be a pneumatic cylinder or an electric cylinder. The melon slice support can realize automatic pressing of the melon slice workpiece through the arc segment driving cylinder.

[0048] According to an embodiment of the present invention, the push-pull clamp 3 includes a screw rod 13 , which is slidable relative to the upper end surface of the lower bracket. One end of the screw rod 13 is connected to the arc-shaped pressing block 4 to push or pull the arc-shaped pressing block 4 .

[0049] like Figure 3As shown, according to one embodiment of the present invention, the push-pull clamp may include a push-pull base 11 fixed to a low frame base, and the push-pull base 11 is provided with a rotatable handle 12. One end of the handle is rotatably connected to a screw 13. The handle rotates around the push-pull base to drive the screw to move along the push-pull base, thereby pushing or pulling the arc-shaped pressure block.

[0050] According to one embodiment of the present invention, in addition to the screw 13, the push-pull clamp 3 also includes two nuts. The arc-shaped pressure block 4 is provided with a threaded hole, through which the screw extends. The two nuts are respectively mounted on the screw and are located on either side of the arc-shaped pressure block 4 to restrict movement of the arc-shaped pressure block 4 relative to the screw.

[0051] The melon slice support provided by the utility model is simple to operate and convenient to disassemble. For example, for melon slices of different sizes, the perimeter tire and arc-shaped pressure block can be replaced, and the installation position of the push-pull clamp, roller and roller wheel can be adjusted to accommodate melon slices of different sizes.

[0052] The melon slice support provided by the embodiment of the present invention can be used to manually transfer the melon slice workpiece that has been welded on the mold to the support. The height of the roller wheel used to support the melon slice workpiece is consistent with the height of the melon slice on the mold, and the welded melon slice workpiece can be smoothly rotated onto the melon slice support. After each longitudinal seam is welded, the melon slice workpiece is rotated from the mold along the circumference tire by a distance of the melon slice workpiece width. The longitudinal seams between the melon slice workpieces are welded in sequence. Before welding the last melon slice longitudinal weld seam, the oblong holes are connected to the pin holes on the melon slice workpiece in sequence with pins, and the arc-shaped pressure blocks are pressed in sequence using a push-pull clamp to press the melon slice workpiece onto the circumference tire so that the melon slice workpiece is pressed against the axial outer side of the circumference tire. At this point, the melon slice workpiece fits the circumference tire, and it can be considered that the circumference of the pressed part of the melon slice workpiece is the same as the circumference of the circumference tire. On this basis, the last longitudinal seam is cut and welded to ensure the consistency of the circumference of the entire melon slice ring.

[0053] The above embodiments of the present invention can be combined with each other and have corresponding technical effects.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
