Description

Technical Field

[0001] The utility model specifically relates to the technical field of cutting structures, in particular to a cutting mechanism of a machining center. Background Art

[0002] The cutting mechanism is an important cutting effect of the machining center during processing and production. The workpiece is processed through the installed tools to ensure that the workpiece is processed to the required shape and size. The machining center can realize a variety of processing of the workpiece such as turning, milling, planing, grinding and drilling. A machining center can realize a variety of processing of the workpiece.

[0044] In this embodiment, a T-shaped knife groove 161 is opened at a symmetrical position on the side of the mounting cylinder 16, and a slide groove 162 is opened on both sides of the knife groove 161. Stop blocks 163 with arc-shaped inclined surfaces are installed at both ends of the slide groove 162 near the knife groove 161, and an arc-shaped slider 1631 is fixedly installed at the connection position between the stop block 163 and the slide groove 162. The arc surface of the arc-shaped slider 1631 is installed in contact with the slide groove 162, and a limit block 1632 is fixedly installed on one side of the arc-shaped slider 1631 near the side of the knife groove 161. Multiple groups of return springs 1633 are installed on the inner side of the limit block 1632, and the return spring 1633 is fixedly connected to the side of the knife groove 161.

[0045] In this embodiment, an elliptical tool holder 164 is installed inside the tool groove 161, and a clamping groove 1641 is opened on both sides of the long axis position of the tool holder 164. The width of the clamping groove 1641 is consistent with the thickness of the tool groove 161, and the clamping groove 1641 is clamped and connected to the tool groove 161. A welding hole 1642 is opened at the center of the inner part of the tool holder 164 for welding the tool;

[0046] In this embodiment, an adjustment groove 165 is provided on the side of the mounting cylinder 16 at a position perpendicular to the knife groove 161, and the top of the adjustment groove 165 is connected to the slide groove 162, and guide wheels 167 are movably installed at the positions on both sides of the adjustment groove 165 connected to the slide groove 162, and a pulling wire 168 is installed on the surface of the guide wheel 167, one end of the pulling wire 168 is fixedly connected to the blocking block 163, and an adjustment block 166 is movably installed inside the adjustment groove 165, and the adjustment block 166 is fixedly connected to the other end of the pulling wire 168.

[0047] The working principle of the present invention is as follows: when in use, the tool is welded to the welding hole 1642 of the tool holder 164. During the process of installing the tool, it is only necessary to insert the long axis end of the elliptical tool holder 164 into the top of the tool groove 161 on the side of the mounting cylinder 16, and at the same time align the engaging groove 1641 with the side of the tool groove 161 to engage and slide downward. When it reaches the lowest point, it squeezes the blocking block 163 with the arc-shaped inclined surface, pushing it to move to both sides along the slide groove 162. When the tool holder 164 reaches the lowest point, the return spring 1633 at the bottom of the blocking block 163 acts to limit the tool holder 164.

[0048] On the other hand, during the disassembly process, the operator only needs to push the adjustment block 166 downward along the adjustment slot 165, and the adjustment block 166 will pull the pulling wire 168 to retract. At this time, the return spring 1633 is compressed, and the blocking blocks 163 on both sides are opened. Subsequently, the tool holder 164 is taken out along the tool slot 161 to complete the tool quick change process.

[0049] The driven runner 13 is fixedly mounted on the top of the rotating shaft connected to the mounting cylinder 16. The driven runner 13 is connected to the driving runner 11 through the connecting belt 12. The driving runner 11 is driven by the rotating motor 10 to rotate so that the tool on the cutting edge 14 can effectively rotate and cut.

[0050] During the cutting process, the first drive motor 33 drives the first screw rod 32 to rotate, so that the movable plate can be longitudinally moved and adjusted along the longitudinal slide rail 31 through the longitudinal slider 23, thereby moving the tool to the processing height to meet the processing requirements. The second drive motor 20 drives the second screw rod 24 to rotate, so that the mounting frame 5 drives the rotary cylinder 4 and the cutting assembly 1 to be horizontally adjusted.

[0051] During the processing, when the side of the workpiece needs to be tilted, the rotating cylinder 4 inside the mounting frame 5 drives the mounting plate 15 to rotate at a moving angle, so as to facilitate rotating the processing tool to the angle required for chip cutting, thereby realizing tilted cutting of the workpiece.
