Description

Technical Field

[0001] The invention relates to the technical field of milling machines, and in particular to a gantry milling machine. Background Art

[0002] Gantry milling machine is a common large milling machine. Gantry milling machine is widely used in machinery manufacturing, aerospace, automobile manufacturing, energy, mold manufacturing and other industries. It is named because of its portal frame structure. The gantry milling machine has a portal frame composed of columns and top beams. The frame usually has one or more milling heads that can move laterally along the crossbeam guide rails. Milling heads with horizontal spindles can also be installed on the two columns respectively. These milling heads can move up and down along the column guide rails. In addition, a movable workbench is provided on the horizontal long bed for installing workpieces. The workpiece can be fed longitudinally with the workbench. The main movement of the gantry milling machine is the rotation of the milling cutter. The feed motion is the movement of the workpiece along the longitudinal direction of the worktable and the movement of the milling head along the transverse and vertical directions. By controlling the relative motion trajectory between the milling cutter and the workpiece, the workpiece is cut using the cutting edge of the milling cutter, thereby achieving the processing of various surfaces of the workpiece, such as planes, grooves, steps, inclined surfaces, curved surfaces, etc. By changing the relative position and motion trajectory of the tool and the workpiece, parts of various shapes and sizes can be processed. Modern gantry milling machines are increasingly using CNC technology and are equipped with advanced CNC systems to achieve automated processing. CNC gantry milling machines can accurately control the motion trajectory and cutting parameters of the tool through programming, and can process parts of complex shapes. Summary of the invention

[0019] In this embodiment, through a pre-set program and route, in cooperation with the first motor 5, when the first motor 5 drives the first screw rod 6 to rotate, the position of the clamping mechanism 4 is adjusted to change the position of the plate. At this time, the second motor 202 and the third motor 208 cooperate to drive the second screw rod 203 and the third screw rod 205 to rotate. The threaded connection between the second screw rod 203 and the transverse groove plate 204 is coordinated with the threaded connection between the third screw rod 205 and the slider 207, so that the position between the turning tool mechanism 3 and the plate is changed, so that the turning tool mechanism 3 performs turning processing on the plate.

A turning tool 34 is detachably installed between the curved panels 36, and the top of the outer side of the turning tool 34 is tightly fitted with the elastic pad 39.

[0022] In this embodiment, the fourth motor 32 drives the threaded barrel 33 to rotate, so that the threaded barrel 33 drives the turning tool 34 to rotate at high speed through the threaded cover 37 and the empty groove barrel 38, so that the blade position at the bottom of the turning tool 34 contacts the plate, and the plate is turned during the high-speed rotation. At the same time, when the turning tool 34 is fixed, the turning tool 34 is placed in the empty groove barrel 38, and then the threaded cover 37 is rotated to connect the threaded cover 37 with the threaded barrel 33, driving the empty groove barrel 38 to move upward.

[0025] In the gantry 2, through the pre-set program and route, it cooperates with the first motor 5. When the first motor 5 drives the first screw rod 6 to rotate, the position of the clamping mechanism 4 is adjusted to change the position of the plate. At this time, the second motor 202 cooperates with the third motor 208 to drive the second screw rod 203 and the third screw rod 205 to rotate. The threaded connection between the second screw rod 203 and the transverse groove plate 204 is coordinated with the threaded connection between the third screw rod 205 and the slider 207, so that the position between the turning tool mechanism 3 and the plate is changed, and the turning tool mechanism 3 performs turning processing on the plate. At the same time, during the movement of the turning tool mechanism 3, the transverse groove plate 204 moves up and down inside the support frame 201. During the movement, it is closely fitted with the support frame 201 through the pulley 209, so that the sliding friction force is converted into rotational friction force.

[0026] In the turning tool mechanism 3, the fourth motor 32 drives the threaded barrel 33 to rotate, so that the threaded barrel 33 drives the turning tool 34 to rotate at high speed through the threaded cover 37 and the empty groove barrel 38, so that the blade position at the bottom of the turning tool 34 contacts the plate, and the plate is turned during the high-speed rotation. At the same time, when the turning tool 34 is fixed, the turning tool 34 is placed in the empty groove barrel 38, and then the threaded cover 37 is rotated to connect the threaded cover 37 with the threaded barrel 33, driving the empty groove barrel 38 to move upward. During the upward movement, the contact between the bevel cover 35 and the arc panel 36 makes the arc panel 36 slide inward during the upward movement, and the turning tool 34 is clamped and fixed by the elastic pad 39 on the opposite side of the arc panel 36.
