Description

Technical Field

[0001] This utility model relates to the technical field of drilling and milling machining centers, and in particular to a drilling and milling machining center that facilitates drill bit replacement. Background Technology

[0002] A machining center is an automated machining equipment developed from a general milling machine. Drilling equipment in a machining center is a highly mechatronic CNC machine tool. When drilling and milling machining centers process parts, different drill bits need to be changed when drilling holes of different sizes, and different cutting tools are used frequently. Moreover, after long-term use, the cutting tools will inevitably break, and they need to be replaced in time.

[0003] In existing drilling and milling machining centers, when replacing drill bits, it is necessary to use other tools to disassemble the connecting structure before the drill bit can be removed. This is time-consuming and inconvenient, and it is not convenient to quickly disassemble and replace drill bits. Moreover, the drill bits are heavy, and cutting fluid and other oil stains adhere to their surface during machining, making the drill bits slippery and difficult to pull out. Furthermore, when removing the drill bits, they are easy to slip from under the drill bit mounting seat and fall, potentially damaging the machining center. There is no way to catch the disassembled drill bits or prevent them from slipping and falling.

[0004] Therefore, we provide a drilling and milling machining center that allows for easy replacement of drill bits. Utility Model Content

The receiving plate 13 is slidably engaged with the outside of the drill bit 3 and the bottom of the clamping plate 24 through the inlet / outlet groove 12. The receiving plate 13 is elastically connected to the support plate 14 through the guide rod 31 and the spring 15. When disassembling the drill bit 3, the positioning rod 22 is pulled out and the receiving plate 13 is pressed down. The drill bit 3 slides down from the mounting base 4 and is engaged in the inlet / outlet groove 12 on the surface of the receiving plate 13 through the clamping plate 24. Then, the drill bit 3 is horizontally and stably removed from the inlet / outlet groove 12 to prevent the drill bit 3 from slipping out of your hand and falling.

[0045] Furthermore, when installing the drill bit 3, the receiving plate 13 is pulled down and the spring 15 is stretched. The drill bit 3 is snapped into place on the top of the receiving plate 13 through the inlet / outlet groove 12 and is located directly below the mounting hole 25. At the same time, the receiving plate 13 is released, the spring 15 retracts, and the receiving plate 13 and the drill bit 3 are pulled upward, so that the drill bit 3 and the snapping plate 24 are inserted into the mounting hole 25 and the snapping groove 26. The positioning rod 22 is used to position and connect the drill bit 3 to the mounting base 4.
