[0002] The statements in this part only provide the background technology related to the present disclosure and do not necessarily constitute the prior art.

[0003] A drill milling machine is a device that combines drilling, milling, boring, and grinding, and is applied to the processing of medium and small parts. It is suitable for drilling, reaming, boring, and hole machining; such as using a circular plate, a forming milling cutter, and an end milling cutter, it can machine planes, inclined planes, vertical planes, and grooves, etc. After installing an attachment vertical milling head, it can be used for milling in multiple directions.

[0004] During the actual processing process, it is necessary to perform drilling operations on different surfaces of multiple profiles. At present, a numerical control drill milling machine only has one clamping table and is equipped with one drill milling head, which can only perform one-way processing. The existing clamping table generally uses a clamping block driven by a lead screw mechanism. After the drilling of one surface in the length direction of the profile is completed, it is necessary to rotate the lead screw structure to loosen the clamping block and then take out the profile, turn the profile so that the surface in its thickness direction faces the drill bit direction, and then rotate the lead screw structure again to clamp the profile. If the thickness of the profile is quite different from its length, it takes a certain amount of time to rotate the lead screw structure when clamping after changing the surface, and only one profile can be supported for processing at a time, resulting in low processing efficiency. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a numerical control drill milling machine, and the utility model aims to solve the technical problem of time-consuming profile replacement in a numerical control drill milling machine.

[0008] It is further set that the first table is parallel to the upper side surface of the workpiece, the second table is parallel to the front side surface of the workpiece, and the third table is parallel to the left side surface of the workpiece.

[0029] Embodiment 1

[0030] A numerically controlled drill - milling machine, referring to Figure 1 and Figure 2 , includes a machine tool base 1, a drill bit 2 is arranged above the machine tool base 1, a first table 3 is horizontally arranged on the machine tool base 1, a second table 4 and a third table 5 are vertically arranged on both sides of the horizontal table and perpendicular to the machine tool base 1. The workpiece 7 is fixed on the first table 3, the second table 4 and the third table 5 through a screw 63 clamp 6, and the three tables are respectively parallel to the three side surfaces of the workpiece 7.

[0031] The first table 3 is parallel to the upper side surface of the workpiece 7, the second table 4 is parallel to the front side surface of the workpiece 7, and the third table 5 is parallel to the left side surface of the workpiece 7. After the screw 63 clamp 6 on each table clamps the workpiece 7, the upper side surface of the workpiece 7 faces the drill bit 2, the front side surface of the workpiece 7 faces the drill bit 2, and the left side surface of the workpiece 7 faces the drill bit 2. The workpiece 7 is a rectangular hexahedron, and the upper side surface, the front side surface and the left side surface of the workpiece 7 are arranged facing the upper drill bit 2, and the drill bit 2 drills and mills after moving to the corresponding side surface of the workpiece 7.

[0032] A plurality of installation grooves 8 are opened on the machine tool base 1, positioning pins 9 are arranged in the installation grooves 8, the first table 3, the second table 4 and the third table 5 are respectively arranged on one side of the positioning pins 9, the positioning pins 9 can be welded and fixed in the installation grooves 8, and the arrangement of the positioning pins 9 plays a positioning role when the first table 3, the second table 4 and the third table 5 are installed.

[0033] The first table surface 3, the second table surface 4, and the third table surface 5 are respectively installed with slide rails 14. A lead screw 63 clamp 6 is slidably installed on the slide rails 14. An existing linear guide rail can be used to drive the lead screw 63 clamp 6 to move along the slide rails 14. The lead screw 63 clamp 6 includes a bottom plate 61. Blocks 62 are arranged at both ends of the bottom plate 61. A lead screw 63 is arranged through the blocks 62. A handle 64 is arranged at one end of the lead screw 63. By rotating the handle 64, the lead screw 63 is driven to rotate. The end of the lead screw 63 abuts against the workpiece 7, and the workpiece 7 is pressed against the baffle to complete the clamping of the workpiece 7.

[0034] A bed body 10 is arranged on one side of the machine tool base 1. A support arm 11 is arranged on the top end of the bed body 10. A drill bit 2 is installed below the support arm 11. The support arm 11 is rotatably connected to a main shaft 12 below. A drill bit clamp 13 is arranged at the end of the main shaft 12. One end of the main shaft 12 can be connected to a driving motor. The rotation of the main shaft 12 drives the drill bit clamp 13 to rotate, and the drill bit clamp 13 drives the drill bit 2 to rotate.

[0035] The drill bit clamp 13 clamps and installs the drill bit 2. An existing clamp can be used to clamp the drill bit 2.

[0037] The working principle of the present utility model is as follows:

[0038] The clamps arranged on each table surface respectively clamp the workpiece 7. The surfaces to be machined of each workpiece 7 face upward. The three table surfaces are respectively parallel to the three side surfaces of the workpiece 7. By programming, the side surfaces of the three workpieces 7 facing the drill bit 2 are drilled in sequence. After the drilling is completed, the positions of the clamps are not adjusted. Only the lead screws 63 of the clamps on the first table surface 3 and the second table surface 4 need to be slightly rotated to loosen the machined workpieces 7.
