[0055] A method for using a fast and stable foot milling device, characterized in that it comprises the following steps:

[0056] S1. Preliminary positioning: The air extraction pipe is connected to the air pump to extract the air inside the rubber box so that the workpiece is tightly adsorbed on the top surface of the rubber box for preliminary fixation;

[0057] S2. Alignment adjustment: adjust the clamping plate, change the position of the fulcrum of the positioning rod, push the adjustment rod along the adjustment hole, observe the scale line while moving the adjustment rod, and align the processing part with the milling cutter;

[0058] S3, re-positioning: the first cylinder drives the positioning rod to rotate along the connection point, and the positioning block at one end of the positioning rod is used to clamp the workpiece;

[0059] According to the above technical features, in step S1, when the workpiece is placed on the top of the exhaust pipe, the through hole of the workpiece is staggered with the air suction hole.

[0060] According to the above technical features, in step S2, the position of the clamping plate is adjusted according to the thickness of the clamping position of the workpiece, and when the positioning block moves to the bottom, the distance between the bottom surface and the top surface of the tray is equal to the thickness of the clamping position of the workpiece.

[0061] The working principle and use process of the present invention are as follows: when working on a workpiece, the workpiece is placed on the top of the rubber box 503, the air extraction pipe 506 is connected to the air pump, and the air inside the rubber box 503 is extracted. The filter 505 can prevent debris from being sucked into the rubber box 503, and the air pressure inside the rubber box 503 is reduced. The second spring 507 plays a supporting role, and the workpiece is tightly adsorbed on the top surface of the rubber box 503 for preliminary fixation;

[0062] After preliminary positioning, the clamping plate 303 is removed, and the position of the clamping plate 303 is adjusted according to the thickness of the workpiece, the first mounting hole 302 is aligned with the first positioning hole 304, the clamping plate 303 is fixed, and then the second mounting hole 307 is aligned with the second positioning hole 308 to install the positioning rod 306, and the connection position of the positioning rod 306 and the clamping plate 303 is changed, and then the adjustment rod 509 inside the adjustment hole 508 is slowly pushed, and the anti-skid rod 7 moves along the anti-skid groove 6 to ensure that the scale line 510 is at the top, which is convenient for observation, and the position of the rubber box 503 is adjusted. The scale line 510 is observed while moving until the milling cutter is facing the milling position to improve the accuracy of milling;

[0063] The first cylinder 305 pushes the positioning rod 306 to rotate with the fulcrum as the axis. The fulcrum is the connection point between the positioning rod 306 and the clamping plate 403. The two positioning blocks 310 squeeze the two sides of the top surface of the workpiece. When the positioning block 310 clamps and fixes the workpiece, the soft pad 405 at the bottom end of the positioning pin 403 first contacts the top surface of the workpiece. At this time, if the top of the workpiece is uneven, the bottom end of the corresponding positioning pin 403 will pierce the groove, and the remaining positioning pins 403 move, and the first spring 404 contracts. The positioning pin 403 is fixed in the groove to prevent the workpiece and the positioning block 410 from sliding during the clamping process, thereby improving the clamping accuracy.

[0064] During the milling process, the second cylinder 805 is started at the same time as the first cylinder 305 is started, and the second cylinder 805 pushes the rotating rod 804, thereby pushing the baffle 802 to rotate for shielding, so as to prevent the flying debris from causing injury to the operator;

[0065] After the milling is completed, when performing defect operation, if the next processing is for a workpiece of the same size, the adjustment step can be skipped, and the workpiece can be directly placed on the top of the rubber box 503, and then the first cylinder 305 is started to clamp and fix it. The clamping is fast and convenient, the operation is simple, and the work efficiency is improved.

[0066] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
