[0027] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0028] Specifically, Figures 1 to 6 As shown, a floating electromagnet positioning mechanism comprises an electromagnet mounting seat 1, wherein two sets of electromagnetic positioning components 2 are arranged inside the electromagnet mounting seat 1;

[0029] The electromagnetic positioning assembly 2 includes a support plate 21 , a floating body 22 , a hinge support 23 , an electromagnet mounting plate 24 , an electromagnet 25 and an adjusting screw 28 .

[0030] It should be noted that for Figure 1 The lower workbench is marked with A, the upper workbench is marked with B, and the machine body is marked with C.

[0031] The support plates 21 are symmetrically arranged in two groups, and the floating body 22 is hinged to the support plates 21 via a pin shaft 26 .

[0032] The hinge supports 23 are provided in two groups and are fixedly connected to the two ends of the top of the floating body 22 by bolts.

[0033] Both ends of the electromagnet mounting plate 24 are rotatably connected to the hinge support 23 via a rotating shaft 27 .

[0034] The electromagnet 25 is fixedly mounted on the top of the electromagnet mounting plate 24 .

[0035] The surface of the electromagnet mounting seat 1 is provided with a dust cover 3 adapted to the electromagnetic positioning assembly 2;

[0036] It should be noted that the electromagnet 25 is firmly mounted on the electromagnet mounting plate 24, and the two ends of the electromagnet mounting plate 24 are provided with a rotating shaft 27, and the rotating shaft 27 is matched with the hinge support 23 for travel rotation, which is regarded as the X axis; the hinge support 23 is mounted on the floating body 22, and the floating body 22 is hingedly connected with the support plate 21 through the pin shaft 26, which is regarded as the Y axis;

[0037] The above structures together constitute an articulated connection in the X and Y directions, and the electromagnet 25 can rotate freely in these two directions. Therefore, the working plane of the electromagnet 25 can be adjusted in two directions in the X and Y planes to form a floating working plane.

[0038] In addition, the adjustment amount of the electromagnet working plane is controlled by the adjusting screw at the rear, and the initial posture of the electromagnet working plane can also be adjusted.

[0039] The specific working method is described below with specific embodiments: Example 1

[0040] The workbench enters the working area and switches between high and low speeds when it approaches the electromagnetic positioning device by 400mm. When it approaches the electromagnetic positioning device by about 20mm, the workbench triggers an in-position signal, and the electromagnet is energized to generate suction. The moment the workbench approaches, the floating adjustment of the electromagnet working plane is completely attracted to the workbench plane, exerting the maximum suction force of the electromagnet, so that the workbench is well positioned and fixed, and the working frame remains stable during the cutting process.

[0041] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above-mentioned concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
