DETAILED DESCRIPTION

[0023] The present application will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams and only schematically illustrate the basic structure of the present application, and therefore only show the components related to the present application.

[0024] As Figures 1 to 5As shown, the laser cutting tool of the utility model includes a bearing plate 1, a plurality of support plates 2 are arranged on the bearing plate 1 at intervals, and the plurality of support plates 2 surround to form a central region 13 and a peripheral region 14. A plurality of support columns 3 are arranged in the central region 13 and are used to support the shell member to be cut. The bearing plate 1 is also provided with a plurality of pressing assemblies 4, and the plurality of pressing assemblies 4 are located on the side of the support plate 2 facing the peripheral region 14 and are used to press the shell member on the bearing plate 1.

[0025] In specific implementation, the shell member to be cut is placed in the central region 13 of the bearing plate 1 and is preliminarily supported by the support column 3. Then, the shell member is pressed on the bearing plate 1 by operating the pressing assembly 4, so that the shell member is ensured not to move or shake during the cutting process.

[0026] The bottom of the support plate 2 is fixed on the bearing plate 1 by a screw, and the threaded hole on the support plate 2 or the bearing plate 1 can be a slot hole, so that the position of the support plate 2 can be adjusted to adaptively form precise and stable support for the shell member. In addition, the pressing assembly 4 is located on the outer side of the support plate 2, and the shell member is fixed in the up-down direction by the support plate 2 and the pressing assembly 4, so that the shell member is in a stable state during the cutting process, thereby ensuring the cutting effect.

[0027] Further, a light barrier 5 is arranged between two adjacent support plates 2, and the light barrier 5 and the support plate 2 surround to form a relatively closed region in the horizontal direction, that is, the aforementioned central region 13 and peripheral region 14. Since strong light generated by laser cutting will be reflected on the bearing plate 1 during the laser cutting process, the side of the shell member relatively facing the bearing plate 1 will be damaged. Therefore, the light barrier 5 is specially arranged between the adjacent support plates 2, so as to reduce the damage to the shell member.

[0028] The top of the support plate 2 extends upward and is provided with a support protrusion 6 in the region relatively close to the peripheral region 14. The support protrusion 6 can further improve the support stability of the shell member, especially for the concave-convex shell member, which can better adapt to the shape and provide stable support.

[0029] The top of the support column 3 is provided with a support disc 7, and the support disc 7 can increase the contact area between the support column 3 and the shell member and improve the stability of the support.

[0030] In other embodiments, the support disc 7 can be made of rubber material to avoid bumping the surface of the shell member.

[0031] The bearing plate 1 is provided with a limiting plate 8, the limiting plate 8 comprises an inclined plate 81 and a vertical plate 82. The bottom of the vertical plate 82 is connected with the bearing plate 1, the bottom of the inclined plate 81 is connected with the top of the vertical plate 82, and the bottom of the inclined plate 81 is inclined towards the center area 13. The limiting plate 8 can further limit the movement of the shell member during cutting, and ensure the cutting accuracy.

[0032] The limiting plate 8 can form a certain guiding effect on the shell member, especially when placing the shell member towards the center area 13.

[0033] The pressing assembly 4 comprises a rotary pressing cylinder 41, a pressing plate 42 and a pressing jaw 43. The pressing plate 42 is connected with the piston rod of the rotary pressing cylinder 41, and the pressing jaw 43 is connected with the pressing plate 42. When the rotary pressing cylinder 41 works, the piston rod drives the pressing plate 42 and the pressing jaw 43 to move downwards, and the shell member is pressed on the bearing plate 1.

[0034] The bearing plate 1 is provided with a weight-reducing cavity 9, and the weight-reducing cavity 9 is located in the center area 13 of the bearing plate 1. The weight-reducing cavity 9 can reduce the weight of the whole tooling, and facilitate carrying and moving.

[0035] The upper side of the bearing plate 1 is provided with a lifting ring 10, and the lifting ring 10 facilitates lifting the tooling as a whole by using lifting equipment to move or install.

[0036] In addition, the laser cutting tooling further comprises a support frame 11, the support frame 11 is connected with the lower side of the bearing plate 1, and the bottom of the support frame 11 is provided with a fixing plate 12 used for being connected with a workbench. The tooling is fixed on the workbench through the fixing plate 12, so that the stability of the tooling during cutting is ensured.

[0037] In some other embodiments, the fixing plate can be provided with a positioning pin hole and a threaded hole, so as to ensure the installation accuracy.

[0038] Working principle:

[0039] In use, first, the shell member to be cut is placed in the center area 13 of the bearing plate 1 and is preliminarily supported by the support column 3 and the support disc 7. Then, the rotary pressing cylinder 41 is operated, so that the piston rod drives the pressing plate 42 and the pressing jaw 43 to move downwards and press the shell member on the bearing plate 1. Next, the laser cutting equipment is started to cut the shell member. During cutting, the light shield plate 5 shields the light generated by laser cutting, so as to avoid damaging the side of the shell member facing the bearing plate 1 after reflection. After cutting, the rotary pressing cylinder 41 is operated, so that the piston rod drives the pressing plate 42 and the pressing jaw 43 to move upwards, the pressing of the shell member is released, and then the cut shell member is taken out.

[0040] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from this still fall within the scope of protection of the present application.
