Description

TECHNICAL FIELD

[0002] The four-axis machining center is a machining center with an additional rotating shaft, vertical (A-axis) and horizontal (B-axis), which can realize four-axis four-linkage. The four-axis machining center is generally used for products that cannot be processed by three-axis due to depth and angle limits, such as fan blades, worms, and deep cavities. It can process rotating surfaces, such as shaft parts.

[0074] Example 8

[0075] This embodiment describes a method for milling a four-axis inclined plane using the milling fixture of Embodiment 7, including the following steps:

[0076] S1. Place the workpiece to be processed between the fixed clamping head 210 and the movable clamping head 211, with the bottom surface of the workpiece in contact with the top seat 23. Adjust the height of the telescopic heads 212 on the fixed clamping head 210 and the movable clamping head 211 according to the thickness of the workpiece. Use the main lead screw 22 to drive the push frame 201 to move on the connecting block 200, and push the movable clamping head 211 to continuously approach the fixed clamping head 210 to clamp and fix the workpiece to be processed. During the movement of the movable clamping head 211, the guide wheel 2111 on the slider 2110 moves and rotates along the inner wall of the mounting base 20.

[0077] S2. Pull out the two support beams 301, and then adjust the position of the sliding beam 30. When the support beams 301 are released, the two support beams 301 move closer to each other under the action of the return spring 303, and are fixed to the mounting base 20 by the locking block 3010. Then rotate the first set of lead screws 32 at both ends of the sliding beam 30, and use the first set of lead screws 32 to drive the first threaded seat 320 to move inside the first slide groove 300. At this time, the support rod 310 supports the support base 31, and supports and fixes the two ends of the bottom surface of the workpiece to be processed. Rotate the two adjusting arms 40 to the appropriate position, and then adjust the position of the arc frame 411 by the second set of lead screws 42. Adjust the position and height of the clamping rollers 413 on the arc frame 411, and use the locking nut to fix the position of the clamping rollers 413, and clamp and fix the ends of the two workpieces to be processed.

[0078] S3. Attach the base 1 to the chuck of the four-axis machining center via the clamping body 10, and use the four-axis machining center to perform milling and drilling on the workpiece.
