[0002] In the field of machining, processing large and complex structural parts has always been a challenge. Traditional five-axis machine tools have many shortcomings in the machining process, such as: a significant bottleneck in processing efficiency, making it difficult to meet the needs of aerospace, automotive mold and other fields; limited precision in machining complex curved surfaces, failing to meet the requirements of high-precision parts; the dynamic performance and stability of machine tools need to be enhanced, and problems such as insufficient rigidity and interference are prone to occur when machining large-sized workpieces; insufficient multi-functional composite machining capabilities, making it difficult to cope with the machining of multi-directional composite features; and insufficient self-sufficiency in domestic high-end equipment, leaving gaps in equipment for complex and high-precision machining.

[0003] Therefore, there is an urgent need for a processing equipment that can solve the above problems. Utility Model Content

[0025] Example:

[0026] Combined with appendix Figure 1-3 This embodiment discloses a gantry five-axis machine tool with an angle head, comprising:

[0027] The gantry frame structure 100 includes a base 101, a workbench 102 disposed on the upper part of the base 101, a left column 103 and a right column 104 disposed on both sides of the base 101, and a front door 105 and a rear door 106 disposed at both ends of the base 101 and connecting the left column 103 and the right column 104. It also includes a crossbeam 107, which is supported on the top of the left column 103 and the right column 104.

[0028] A five-axis motion system includes a Y-axis linear motion mechanism 200 disposed between the crossbeam 107 and the left column 103 and the right column 104, an X-axis linear motion mechanism 300 disposed along the length of the crossbeam 107, and a Z-axis linear motion mechanism 400 disposed on the X-axis linear motion mechanism 300. A C-axis rotation mechanism 500 is also disposed at the end of the Z-axis linear motion mechanism 400, and an A-axis rotation mechanism 600 is disposed on one side of the C-axis rotation mechanism 500.

[0029] Angle head 700 is mounted on A-axis rotation mechanism 600. The output end of angle head 700 is provided with tool mounting interface, and tool 800 is mounted on tool mounting interface.

[0030] The control system is used to control the movement of the X-axis linear motion mechanism 300, the Y-axis linear motion mechanism 200, the Z-axis linear motion mechanism 400, the A-axis rotation mechanism 600, the C-axis rotation mechanism 500, and the angle head.

[0031] The Y-axis linear motion mechanism 200 includes a first electric linear guide rail disposed on the top of the left column 103 and the right column 104, and the crossbeam 107 is fitted onto the slider of the first electric linear guide rail; the X-axis linear motion mechanism 300 includes a second electric linear guide rail disposed on the crossbeam 107, and a Z-axis connecting beam is fitted onto the slider of the second electric linear guide rail; the Z-axis linear motion mechanism 400 is vertically disposed in the Z-axis connecting beam, and the crossbeam 107 is provided with a moving channel 108 corresponding to the Z-axis linear motion mechanism 400; the Z-axis linear motion mechanism 400 includes a third electric linear guide rail, and the Z-axis connecting beam is fitted onto the slider of the third electric linear guide rail.

[0032] The C-axis rotation mechanism 500 is located at the bottom of the Z-axis linear motion mechanism 400 and rotates along the axial direction of the Z-axis linear motion mechanism 400. The swing range of the C-axis rotation mechanism 500 is ±360°.

[0033] The rotation axis of the A-axis rotation mechanism 600 is perpendicular to the rotation axis of the C-axis rotation mechanism 500, and the swing range of the A-axis rotation mechanism 600 is ±110°; the angle head is installed on the A-axis rotation mechanism 600 through an ISO / BT standard interface.

[0034] During linear motion along the Y-axis, the crossbeam 107 moves laterally (left and right) along the Y-axis via the first electric linear guide rails at the top of the left and right columns 104, thereby positioning the entire machining actuator within the width range of the gantry frame.

[0035] During linear motion along the X-axis, the Z-axis connecting beam moves back and forth along the X-axis direction (the length direction of the beam 107) via the second electric linear guide on the crossbeam 107, further reducing the lateral range of the machining position.

[0036] During Z-axis linear motion, the third electric linear guide inside the Z-axis linear motion mechanism 400 drives the tool to move up and down along the Z-axis (vertical) direction, thereby adjusting the vertical distance between the tool 800 and the workpiece.

[0037] When the C-axis rotates, the C-axis rotation mechanism at the end of the Z-axis linear motion mechanism 400 can rotate infinitely around the Z-axis axis ±360°, driving the angle head and the tool to rotate in the horizontal plane and adjust the circumferential machining angle of the tool.

[0038] When the A-axis rotates, the A-axis rotation mechanism 600 is perpendicular to the C-axis, with a swing range of ±110°, which can drive the angle head 700 to tilt in the vertical plane, allowing the tool to cut into the workpiece at any angle.

[0039] The angle head 700 is mounted on the A-axis via an ISO / BT standard interface. Its output end tool mounting interface can fix different types of tools 800. In conjunction with the rotation of the A and C axes, it can achieve full-degree-of-freedom adjustment of the tool posture.

[0040] This embodiment enhances the machining flexibility of five-axis machining by expanding the tool's directional degrees of freedom, which greatly increases the application difficulty. However, precisely because of the addition of the angle head, the utilization rate of the equipment is greatly improved, and more complex multi-angle products can be processed, as follows:

[0041] Aerospace: integral machining of launch vehicle fuel tanks (reducing welding joints by 80%); Energy equipment: deep hole group machining of nuclear power steam generator tube sheets (hole depth-to-diameter ratio 30:1); Medical devices: integrated molding of porous structures for orthopedic implants (porosity accuracy ±2%).

[0042] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
