[0035] The fixture 2 includes a carrier plate 21, which has a plurality of through holes 201 that penetrate the carrier plate 21 along its thickness direction.
[0036] The product fixing component 3 includes an electromagnet 31 and a magnetic conductive component 32. The electromagnet 31 is disposed on the mounting base 1, and the magnetic conductive component 32 is disposed in the through hole 201 and protrudes out of the through hole 201. The electromagnet 31 and the magnetic conductive component 32 are in contact.
[0037] Specifically, in this embodiment, the mounting base 1 is fixed to an external CNC machine tool machining center, and the carrier plate 21 is fixed to the mounting base 1. The carrier plate 21 is used to support and fix the external workpiece 100. The carrier plate 21 is machined with multiple through holes 201. The product fixing component 3 includes an electromagnet 31 and multiple magnetic conductive components 32. The magnetic conductive components 21 are made of silicon steel sheets. The electromagnet 31 is fixed to the mounting base 1 and located directly below the carrier plate 21. One magnetic conductive component 32 is fixed in one through hole 201. The electromagnet 31 and the magnetic conductive component 32 are in contact. When the electromagnet 31 is connected to an external power source, it generates magnetism and attracts the metal part of the product fixing component 3 through the magnetic conductive component 32, thereby achieving the purpose of firmly fixing the external workpiece 100 to the carrier plate 21.
[0038] By installing multiple magnetic conductive elements 32 on the carrier plate 21, the electromagnet 31 is located below the carrier plate 21 and is in contact with the magnetic conductive elements 32. The magnetism generated by the electromagnet 31 when energized attracts and fixes the metal part of the external workpiece 100 through the magnetic conductive elements 32, thereby achieving the purpose of quickly fixing the external workpiece 100, improving loading and unloading efficiency, and reducing production costs.
[0039] The mounting base 1 is provided with a through hole 101, through which the electromagnet 31 passes. The mounting base 1 includes a support plate and a base plate connected to the support plate. The through hole 101 is located on the base plate. The electromagnet 31 is located between two support plates. The electromagnet 31 passes through the through hole 101 and abuts against the magnetic conductive element 32. The mounting base 1 protects the electromagnet 31 and improves its service life.
[0040] Please see Figures 4 to 5 The carrier plate 21 includes a base plate 211 and a hole positioning member 212. The hole positioning member 212 is disposed on the base plate 211 and protrudes from the base plate 211. The hole positioning member 212 matches the hole on the external workpiece 100 to pre-position the external workpiece 100.
[0041] The material carrier plate 21 further includes a mold closing positioning member 213, which is disposed on the substrate 211 and protrudes from the substrate 211. The height of the mold closing positioning member 213 protruding from the substrate 211 is greater than the height of the hole positioning member 212 protruding from the substrate 211.
[0042] The fixture 2 also includes an upper cover plate 22, which is movably connected to the material carrier plate 21. The upper cover plate 22 is provided with a limiting hole 221, and the mold closing positioning member 213 extends into the limiting hole 221. The mold closing positioning member 213 is elongated, and the limiting hole 221 is elongated, to ensure the accuracy of the upper cover plate 22 in closing the material carrier plate 21.
[0043] The upper cover plate 22 presses the external workpiece 100 onto the carrier plate 21 for upper surface protection. The upper cover plate 22 is fixedly connected to the carrier plate 21 to avoid damage to the surface of the external workpiece 100 during the processing.
[0044] The carrier plate 21 also includes a product fixing part 214, which protrudes from the upper surface of the substrate 211. The height of the product fixing part 214 protruding from the substrate 211 is less than the height of the hole positioning part 212 protruding from the substrate 211. The through hole 201 is located in the product fixing part 214. The outer contour of the product fixing part 214 matches the external workpiece 100 to pre-position the external workpiece 100.
[0045] Please see Figure 6The hole positioning component 212 includes a mounting sleeve 2121 and a tapered portion 2122. The mounting sleeve 2121 is disposed on the substrate 211 or the product fixing part 214, and the tapered portion 2122 is disposed on the mounting sleeve 2121 and protrudes from the mounting sleeve 2121. Preferably, mounting holes are machined in the substrate 211 or the product fixing part 214 at preset positions, the mounting sleeve 212 is fixed in the mounting holes, and the tapered portion 2122 is connected to the mounting sleeve 212. The structure of the tapered portion 2122 facilitates fine adjustment of the external workpiece 100 and improves the processing accuracy.
[0046] Please see Figure 7 The material fixing fixture for CNC also includes a pressing component 4, which is located on the mounting base 1 and is used to press the upper cover plate 22 so that the upper cover plate 22 fixes the external workpiece 100 to the material carrier plate 21, thereby improving the controllability of safe production.

One end of the swinging member 42 is rotatably connected to the connector 41, and the other end of the swinging member 42 is pressed against the upper cover plate 22. The swinging member 42 and the connector 41 are connected by a rotating shaft, which facilitates the handling of external workpieces.
[0048] The upper cover plate 22 is provided with a groove 222, which is located away from the material carrier plate 21. The other end of the swing member 42 is pressed against the groove 222. The groove 222 ensures the consistency of the position of the swing member 42 pressing against the upper cover plate 22.
