Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of machining power head, in particular to a kind of double spindle turning and milling center machine tool. BACKGROUND

[0002] Chinese patent publication number CN110948289A discloses a machining center on April 3, 2020, which includes a rack, a clamp assembly, a horizontal guide rail, a front and rear movable seat, a vertical movable seat, a horizontal movable seat, a first mounting block, a vertical tool magazine, a rotating shaft, a driver, a tool holder, and a rotating tool shaft. The structure improves the three-dimensional drive and tool magazine of the machining center, making the machining center more accurate and allowing a single driver to drive multiple tools simultaneously for machining workpieces. However, the rotating tool shaft on the vertical tool magazine can only process workpieces clamped on the machining center spindle vertically to the spindle. When certain workpieces need to be processed with inclined holes (holes inclined relative to the spindle), the workpieces need to be disassembled, re-clamped, and then drilled, resulting in low processing accuracy and low automation level.

Attached Figure Description

[0013] Figure 1 This is a schematic diagram of an embodiment of the present invention.

[0014] Figure 2 for Figure 1 Another structural diagram from a different angle. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] See Figure 1 and Figure 2 As shown, a dual-spindle milling and turning center includes a frame 1 and a power head 6. The frame 1 is equipped with a three-axis motion mechanism, a swing drive device 5, and a tool magazine 7. The power head 6 is connected to the three-axis motion mechanism through the swing drive device 5. The three-axis motion mechanism is used to control the longitudinal, transverse, and vertical movements of the swing drive device 5 and the power head 6. The swing drive device 5 controls the swing of the power head 6. The power head 6 is equipped with a tool chuck and a rotary power device for driving the tool chuck to rotate (this is prior art and will not be described in detail here). The tool magazine 7 is located on the outer side of the power head 6 and has two or more tool insertion positions 73.

[0017] The tool magazine 7 is a rotary tool magazine, which includes a support frame 71, a moving track 75, and tool cylinders 72. The support frame 71 is fixedly connected to the frame 1. The moving track 75 is mounted on the support frame 71 and driven by a motor. Multiple tool cylinders 72 are provided and mounted on the moving track 75. Tool inserts are provided on the tool cylinders 72, and the tool inserts form the tool insertion position 73.

[0018] The three-axis motion mechanism is also equipped with a secondary power head 9 and a tool holder 8.

[0019] The three-axis motion mechanism includes a transverse sliding frame 2, a longitudinal sliding frame 3, and a vertical sliding frame 4. The transverse sliding frame 2 is slidably mounted on the frame 1, and the frame 1 and the transverse sliding frame 2 are connected by a transverse drive device 11. The longitudinal sliding frame 3 is slidably mounted on the transverse sliding frame 2, and the longitudinal sliding frame 3 and the transverse sliding frame 2 are connected by a longitudinal drive device 21. The vertical sliding frame 4 is slidably mounted on the longitudinal sliding frame 3, and the vertical sliding frame 4 and the longitudinal sliding frame 3 are connected by a vertical drive device 41.

[0020] The auxiliary power head 9 and the tool holder 8 are mounted on the vertical sliding frame 4.

[0021] The frame is also equipped with a main spindle 10 and a secondary spindle 20 for clamping workpieces.

[0022] The main spindle 10 is movably mounted on the frame 1, and the auxiliary spindle 20 is fixedly mounted on the frame 1.

[0023] The frame is also provided with a central frame 30, a longitudinal adjustment table 40, and a clamping head 50.

[0024] Its working principle is as follows: When the three-axis motion mechanism and the swing drive device 5 return to the origin, the rotation axis of the power head 6 is aligned with a tool insertion position 73 of the rotary tool magazine. The three-axis motion mechanism controls the lateral movement of the power head 6, and the tool chuck of the power head 6 can hold a tool from the tool insertion position 73. The three-axis motion mechanism controls the power head 6 to reset, thus removing a tool and proceeding with subsequent drilling of the workpiece on the spindle. By controlling the swing drive device 5 to swing the power head 6, the relative angle between the drilling and the spindle is changed, achieving the machining of inclined holes. When machining other types of holes is required, the three-axis motion mechanism and the swing drive device 5 drive the power head 6 to reset and insert the tool into the original position. After releasing the tool chuck, it returns to its original position. By controlling the rotation of the rotary tool magazine, the required tool is moved to the position aligned with the power head 6, and the power head 6 installs another tool using the same method as the first tool loading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
