[0028] The present utility model provides a slicing jig, Figures 1 to 3 which is a specific embodiment of the slicing jig provided by the present utility model.

[0029] Refer to Figures 1 to 3 , the slicing jig includes:

[0030] Base 1, on both side edges of the upper surface of the base 1, receiving grooves are provided, and the receiving grooves are provided with openings 12 facing the outside of the base 1;

[0031] Pressing plate 2, the pressing plate 2 is arranged on the upper side of the base 1, the pressing plate 2 is provided with limiting blocks 21 corresponding to the receiving grooves, and a limiting gap 22 for limiting the metal product 3 is provided between the limiting blocks 21 and the side surfaces of the receiving grooves;

[0032] The metal product 3 has opposite first side panels, second side panels and opposite third side panels and fourth side panels. The receiving grooves include a plurality of first square grooves 111, second square grooves 112, first triangular grooves 113, and second triangular grooves 114. The opening 12 of the first square groove 111 is for the first side panel to extend out of the base 1, the opening 12 of the second square groove 112 is for the third side panel to extend out of the base 1, the opening 12 of the first triangular groove 113 is for part of the first side panel and the third side panel to extend out of the base 1, and the opening 12 of the second triangular groove 114 is for part of the second side panel and part of the fourth side panel to extend out of the base 1.

[0033] Wherein, after the slicing fixture fixes the metal product 3, the part of the metal product 3 extending out of the base 1 is ground and sliced by a grinding machine. After slicing, an OMM measuring device is used to measure the thickness of the side panel located in the grinding gap.

[0034] The slicing fixture of the present utility model fixes the metal product 3 through the first square groove 111, the second square groove 112, the first triangular groove 113, and the second triangular groove 114, and makes the metal product 3 in four different position states. The structures of the parts of the metal product 3 extending out of the base 1 are also different. Thus, the grinding machine can simultaneously slice the metal products 3 in four different states, and multiple first grooves, second square grooves 112, first triangular grooves 113, and second triangular grooves 114 can be respectively provided, and multiple metal products 3 can be sliced at one time. Multiple measurement data of multiple metal products 3 at various different positions can be obtained in one slicing, and the efficiency is higher. Due to the fixing effect of the limiting grooves and the limiting blocks 21 on the metal product 3, the problem that the metal product 3 moves during the slicing process, resulting in errors in the measurement results, can be avoided.

[0035] The pressing plate 2 is provided with positioning holes 23, and the base 1 is provided with positioning posts 13 for extending into the positioning holes 23. Through the positioning cooperation of the positioning holes 23 and the positioning posts 13, it is convenient for the testers to operate and can improve the alignment accuracy of the pressing plate 2 and the base 1. In addition, when the pressing plate 2 is misaligned during installation, the pressing plate 2 can be restricted by the positioning posts 13 to avoid the limiting blocks 21 on the pressing plate 2 being misaligned and damaged while the metal product 3 is damaged.

[0036] The end of the positioning post 13 is provided with a guiding structure 131. Specifically, the guiding structure 131 is a hemispherical structure. The hemispherical structure has an arc-shaped surface that can provide a guiding effect for the pressing plate 2, making it easier for the positioning post 13 to accurately enter the positioning hole 23, thus simplifying the installation between the pressing plate 2 and the base 1 and making the operation more simple and convenient.

[0037] A number of screw holes 14 are provided on the base 1, and mounting holes 24 corresponding to the positions of the screw holes 14 are provided on the pressing plate 2. The screw holes 14 and the mounting holes 24 are connected by screws. The corresponding screw holes 14 and mounting holes 24 are connected by screws, that is, the pressing plate 2 and the base 1 are connected by screws, which can fix the pressing plate 2 and the base 1 together, and can prevent the pressing plate 2 from loosening during the slicing process and causing the metal product 3 to move, resulting in poor slicing effect; the screw connection can ensure the stable and reliable connection between the pressing plate 2 and the base 1, and the installation and disassembly of the screws are simple, which is convenient for the testers to operate.

[0038] A chamfer is provided on the lower side of the limiting block 21. This setting can make the limiting block 21 have no sharp corners, thus avoiding the problem that when the pressing plate 2 presses and fixes the metal product 3, the sharp corners on the limiting block 21 press the product and deform it, resulting in measurement errors.

[0039] A relief groove 25 is provided on the lower side of the pressing plate 2, and the accommodating groove is provided on the bottom surface of the relief groove 25. When the height of the side panel of the metal product 3 is higher than the depth of the accommodating groove, the relief groove 25 can provide space for the part of the side panel that is higher than the accommodating groove, thus preventing the pressing plate 2 from damaging or deforming the metal product 3.

[0040] A first magnetic member is provided on the base 1, and a second magnetic member magnetically connected to the first magnetic member is provided on the pressing plate 2. The first magnetic member and the second magnetic member can be quickly adsorbed, making the alignment and installation between the pressing plate 2 and the base 1 simpler and faster, thus improving the installation efficiency. Optionally, two first magnetic members are provided on the base 1, and the two first magnetic members are respectively arranged at both ends of the base 1, and two second magnetic members corresponding to the two first magnetic members are provided on the pressing plate 2.

[0041] Both the first magnetic member and the second magnetic member are magnets. Magnets have a low cost and can maintain magnetism for a long time without the need for external energy to maintain their magnetic fields, so they have a long service life. Magnets are usually made of metal alloys such as iron, nickel, and cobalt. These materials are relatively abundant and environmentally friendly, and can be recycled and reused.

[0042] The receiving grooves on the two side edges of the base 1 are arranged in central symmetry. That is, the first square groove 111, the second square groove 112, the first triangular groove 113, and the second triangular groove 114 on the two side edges are all centrally symmetric, so that the two side limit blocks 21 of the pressing plate 2 are also centrally symmetric. This setting makes it unnecessary to confirm the left - right orientation of the pressing plate 2 when installing the pressing plate 2, and it can be directly installed, with higher installation efficiency.

[0043] Optionally, the pressing plate 2 is provided with marks corresponding to the two side edges of the base 1. Through the marks, it is convenient for testers to distinguish the metal products 3 on both sides, which is convenient for the measurement personnel to record the measurement data of the metal products 3 on both sides after slicing measurement, and avoids confusion.

[0044] The above are only optional embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural transformations made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present utility model.
