In addition, the bearing structure 34 is a base body, which is movably arranged on the supporting structure 33 to make the milling tool 30 approach or be far away from the positioning structure 32, and the power unit 38 includes a drive to drive the The second motor 38b for the displacement of the bearing structure 34, wherein, based on one side of the positioning structure 32, the displacement direction of the support structure 33 (the moving directions f2, b2 as shown in Figure 1B) and the bearing structure 34 The displacement directions (movement directions f1, b1 as shown in Figure 1B) are perpendicular to each other. For example, a rail 35 is arranged on the upper side of the supporting structure 33, so that the slider 340 under the supporting structure 34 cooperates with the rail 35, and the slider 340 moves on the rail 35, so that the second motor 38b drives the supporting structure 34 performs a short-distance linear displacement along the track 35 relative to the supporting structure 33, so the milling tool 30 can linearly move to a desired planar position or processing position to approach or move away from the positioning structure 32. Specifically, a ball nut (figure omitted) is fixed on the lower side of the bearing structure 34, and a ball screw (figure omitted) is fixed on the supporting structure 33 to engage the ball nut, so that the second motor 38b rotates the The ball screw, because the ball screw only rotates in place without moving, the ball screw actuates the ball nut to produce linear displacement, so that the ball nut linearly drives the bearing structure 34 to move along the track 35, so that the milling cutter The tool 30 is linearly displaced to the required processing position.

In addition, the supporting structure 34 is equipped with a driving group 36 and the milling tool 30 with two brackets 34a, so that the driving group 36 drives the milling tool 30 to rotate, so that the milling cutter 300 is at a target position ( For example, the flange 91 that fits the side 9c of the target 9) remove the burrs of the flange 91 of the target 9.

Then, the second motor 38b displaces the supporting structure 34 close to (moving direction f1 as shown in Figure 1B) the positioning structure 32 (or the placing platform 32a) to displace the milling assembly 3a to the desired position. At the required position, the support structure 33 is linearly slid along the limit structure 37 by the first motor 38a (as the moving direction f2 shown in Figure 1B) to move the milling tool 30, so that the driving group 36 The milling cutter 300 driving the milling tool 30 mills the burrs on the flanges 91 of the four sides 9c of the target 9 so that the milling assembly 3a corresponds to the edges of the positioning structure 32 (or the placing platform 32a) Milling of the target object 9.

After that, the supporting structure 34 is displaced away from the positioning structure 32 (or the placing platform 32a) by the second motor 38b (the moving direction b1 shown in Figure 1B) to move the milling tool 30 to the desired position. At the required position, the support structure 33 is linearly slid along the limiting structure 37 by the first motor 38a (as shown in the moving direction b2 in Figure 1B) to move the milling assembly 3a back to the origin.

In summary, the milling device 3, 3'of the present invention uses the milling assembly 3a to process the burrs of the flange 91 on the side 9c on the raised floor, so as to speed up the production time and improve the production efficiency. Reduce manpower requirements.

Furthermore, the circular displacement (movement directions f1, f2, b1, b2 shown in Figure 1B) of the milling assembly 3a is designed to avoid repeated milling of the milling cutter 300 of the milling tool 30 The flange 91 on the side surface 9c can prevent the flange 91 on the side surface 9c of the target 9 from being over-milled and damaged or the milling cutter 300 from making mechanical noise.
