Description

Technical Field

[0001] This utility model relates to a machining power head, and more particularly to a tool-changeable swing-type power head. Background Technology

[0002] Chinese Patent Publication No. CN110948289A, published on April 3, 2020, discloses a machining center including a frame, a fixture assembly, a horizontal guide rail, front and rear movable seats, a vertical movable seat, a horizontal movable seat, a first mounting block, a vertical tool magazine, a rotary axis, a driver, a tool holder, and a rotary tool axis. This structure improves the three-dimensional drive and tool magazine of the machining center, thereby increasing its accuracy and allowing multiple tools to be driven simultaneously by a single driver to machine workpieces. However, the rotary tool axis on the vertical tool magazine can only machine workpieces clamped on the machining center spindle in a direction perpendicular to the spindle. When machining inclined holes (holes tilted relative to the spindle) is required for some workpieces, the workpiece needs to be disassembled, re-clamped, and then drilled, resulting in low machining accuracy and low automation. Utility Model Content

[0003] The purpose of this utility model is to provide a simple and reasonable structure of a tool-changeable swing-type power head that can be applied to machining centers and CNC machine tools to perform oblique hole machining or different hole shape machining without disassembling the workpiece.

[0004] The purpose of this utility model is achieved as follows:

[0005] A tool-changeable oscillating power head includes a frame and a power head. The frame is equipped with a three-axis motion mechanism, an oscillating drive device, and a tool magazine. The power head is connected to the three-axis motion mechanism via the oscillating drive device. The three-axis motion mechanism controls the longitudinal, lateral, and vertical movements of the oscillating drive device and the power head. The oscillating drive device controls the oscillation of the power head. The power head contains a tool chuck and a rotary power device for driving the tool chuck to rotate. The tool magazine is located on the outer side of the power head and has two or more tool insertion positions.

[0006] The objective of this utility model can also be achieved by the following technical measures:

[0007] As a more specific embodiment, the tool magazine is a rotary tool magazine, which includes a support frame, a moving track, and tool cylinders. The support frame is fixedly connected to the frame. The moving track is mounted on the support frame and driven by a motor. Multiple tool cylinders are provided and mounted on the moving track. Each tool cylinder has a tool insert, which forms the tool insertion position.

[0008] As a further embodiment, the three-axis motion mechanism is also provided with a secondary power head and / or a tool holder.

[0009] As a further embodiment, the three-axis motion mechanism includes a transverse sliding frame, a longitudinal sliding frame, and a vertical sliding frame. The transverse sliding frame is slidably mounted on the frame, and the frame and the transverse sliding frame are connected by a transverse drive device. The longitudinal sliding frame is slidably mounted on the transverse sliding frame, and the longitudinal sliding frame and the transverse sliding frame are connected by a longitudinal drive device. The vertical sliding frame is slidably mounted on the longitudinal sliding frame, and the vertical sliding frame and the longitudinal sliding frame are connected by a vertical drive device.

[0010] As a further embodiment, the frame is also provided with a spindle for clamping workpieces.

[0011] The beneficial effects of this utility model are as follows:

[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 tool-changeable oscillating power head includes a frame 1 and a power head 6. The frame 1 is equipped with a three-axis motion mechanism, an oscillating drive device 5, and a tool magazine 7. The power head 6 is connected to the three-axis motion mechanism through the oscillating drive device 5. The three-axis motion mechanism is used to control the longitudinal, lateral, and vertical movements of the oscillating drive device 5 and the power head 6. The oscillating drive device 5 controls the oscillation 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 a tool cylinder 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 1 is also equipped with a spindle for clamping workpieces, which is not shown in the figure.

[0022] 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.

[0023] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. 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.
