[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, a fan blade turning device includes a fixed platen 1, a rotating chuck 2, a first tool 9, a transfer chuck 4, a tool holder 3, a fixed chuck 5, a third tool 18, and a second tool 10 is connected to the tool holder 3. A cover plate 19 is provided below the fixed platen 1.

[0031] The first tool 9 is installed on the tool moving device, and the tool is driven to move along the X-axis and Y-axis directions by the tool moving device; when the rotating chuck 2 clamps the fan blade 30, the hub end face 30-2 on the fan blade 30 faces upward, and the hub end face 30-2 and the blade end face 30-4 on the fan blade 30 are processed by the first tool 9.

[0032] Specifically, the tool movement device includes a first Y-axis linear module 6, which is fixedly mounted on a fixed platen 1. A first X-axis linear module 7 is mounted on the first Y-axis linear module 6, which is equipped with a tool extension column 8. A first tool 9 is fixedly mounted on the tool extension column 8. The first Y-axis linear module 6 is used to drive the first X-axis linear module 7 along the Y-axis, while the first X-axis linear module 7 is used to drive the tool extension column 8 along the X-axis. The tool extension column 8 is arranged horizontally. The combination of the first Y-axis linear module and the first X-axis linear module enables the first tool 9 to move along both the X-axis and the Y-axis.

[0033] The rotary chuck 2 is connected to the rotary chuck drive motor 13 and is driven to rotate by the rotary chuck drive motor 13. The rotary chuck drive motor 13 is fixedly arranged at the lower end of the fixed table 1, and the rotary chuck 2 is located above the fixed table 1. In this embodiment, the rotary chuck 2 is a three-jaw chuck, which clamps the workpiece in an internal clamping manner. When clamping, the jaws on the three-jaw chuck are in tight contact with the outer cavity side wall 30-6 of the fan blade 30, and the fan blade 30 is placed horizontally in the clamped state. The first tool 9 is moved to perform chip processing on the hub end face 30-2 and the blade end face 30-4 of the fan blade 30, thereby realizing the first processing step of the fan blade 30.

[0034] The transfer chuck 4 is installed on the transfer drive device, and the transfer drive device drives the transfer chuck 4 to move along the X-axis and Y-axis directions; the transfer chuck 4 is connected to the transfer chuck 4 drive motor, and the transfer chuck 4 drive motor drives the transfer chuck 4 to rotate; when the transfer chuck 4 clamps the fan blade 30, the outer cavity on the fan blade 30 faces downward; the second tool 10 extends into the outer cavity and processes the outer end face 30-7, the inner end face 30-8 and the side wall 30-6 of the outer cavity.

[0035] The transfer drive device includes a second X-axis linear module 11, mounted on a second Y-axis linear module 12. The transfer chuck 4's drive motor is mounted on this second Y-axis linear module 12. This motor drives the transfer chuck 4 to rotate horizontally. The combination of the second X-axis linear module 11 and the second Y-axis linear module 12 enables the transfer chuck 4 to move along both the X- and Y-axes. The second X-axis linear module is mounted on the fixed platen 1.

[0036] The transfer chuck 4 can be a three-jaw chuck. The transfer chuck 4 clamps the fan blade 30 in an external clamping manner. During clamping, the clamping claws on the transfer chuck 4 contact the outer side of the hub 30 - 1 of the fan blade 30 .

[0037] By moving the transfer chuck 4 in the X-axis direction, the fan blade 30 can be transferred between different processing stations. That is to say, after the fan blade 30 is processed at the station where the rotating chuck 2 is located, the fan blade 30 can be transferred to the station where the second tool 10 is located by moving the transfer chuck 4 and the second processing step can be performed; when the fan blade 30 is processed at the station where the second tool 10 is located, the fan blade 30 can be transferred to the station where the fixed chuck 5 is located by the transfer chuck 4 and the third processing step can be performed.

[0038] At the same time, the rotary chuck 2 can rotate and move along the Y-axis under the drive of the transfer chuck 4 drive motor. Through the above two movements and in cooperation with the second tool 10, the outer cavity side wall 30-6, the outer end surface 30-7, and the inner end surface 30-8 of the outer cavity can be processed, thereby completing the second processing step of the fan blade 30. In other words, the transfer chuck 4 not only has the function of transferring the workpiece, but also the transfer chuck 4 itself serves as part of the second processing step, cooperating with the second tool 10 to complete the processing task of the fan blade 30.

[0039] The tool holder 3 is provided with an insertion hole, and the handle of the second tool 10 is inserted into the insertion hole; the tool holder 3 is provided with a tool tightening screw 20 for tightening the second tool 10.

[0040] The fixed chuck 5 is disposed on the fixed platen 1. The fixed chuck 5 is provided with at least three jaws, between which a third tool 18 is positioned. The third tool 18 is mounted on a third Y-axis linear module 14. The third tool 18 is driven along the Y-axis by the third Y-axis linear module 14. The third Y-axis linear module 14 is provided with a tool drive motor 15 for rotating the third tool 18. When the fixed chuck 5 clamps the fan blade 30, the inner cavity of the fan blade 30 faces downward. The third tool 18 extends into the inner cavity and processes the inner cavity sidewall 30-9.

[0041] Among them, the claws on the fixed chuck 5 can move along the radial direction of the fixed chuck 5, and the fixed chuck 5 clamps the fan blade 30 by external clamping. During clamping, the chuck on the fixed chuck 5 presses against the outer surface of the hub 30-1 of the fan blade 30.

[0042] A rotating shaft 16 is connected to the tool drive motor 15 and is coaxially arranged with the fixed chuck 5. A third tool 18 is connected to the upper end of the rotating shaft 16. A bearing seat 17 is provided on the third Y-axis linear module. The rotating shaft 16 passes through the bearing seat 17 and rotates in conjunction with the bearing seat 17. The rotating shaft 16 is arranged along the Y-axis and supported by the bearing seat 17, ensuring its stability during rotation.

[0043] In this embodiment, the third tool 18 can be an eccentric boring tool. The third tool 18 is connected to the upper end of the rotating shaft 16. The tool drive motor 15 drives the third tool 18 to rotate, achieving the main motion of the third tool 18. The third tool 18 is driven by the third Y-axis linear module 14 to move along the Y-axis, achieving the feed motion of the third tool 18.

[0044] It is worth mentioning that during the machining process, the fixed chuck 5 does not rotate, and the cutting process of the side wall of the inner cavity is achieved by the rotation of the third tool 18 .

[0045] The utility model includes the following specific steps when processing the fan blades:

[0046] Step 1: Place the fan blade to be processed on the rotary chuck 2, and the rotary chuck 2 clamps the fan blade 30. At this time, the hub end face 30-2 on the fan blade 30 faces upward. The rotary chuck 2 drives the fan blade 30 to rotate, and the hub end face 30-2 and the blade end face 30-4 on the fan blade 30 are processed by the first tool 9; after the processing is completed, the rotary chuck 2 stops rotating.

[0047] Step 2: Rotate the chuck 2 to loosen the fan blade 30, move the transfer chuck 4 to the top of the fan blade 30 and clamp the fan blade 30, and then move the transfer chuck 4 to move the fan blade 30 to the top of the second tool 10; then the transfer chuck 4 rotates and moves downward, and the second tool 10 extends into the outer cavity on the fan blade 30 and processes the outer cavity side wall 30-6, the outer end face 30-7, and the inner end face 30-8 of the outer cavity; after the processing is completed, the transfer chuck 4 stops rotating.

[0048] Step three: The transfer chuck 4 moves the fan blade 30 to the fixed chuck 5 and loosens the fan blade 30. The fixed chuck 5 clamps the fan blade 30. At this time, the inner cavity on the fan blade 30 faces downward; the tool drive motor 15 drives the third tool 18 to rotate, and drives the third tool 18 upward through the third Y-axis linear module. The third tool 18 extends into the inner cavity and processes the side wall 30-9 of the inner cavity; after the processing is completed, the third tool 18 stops rotating and withdraws from the inner cavity.

[0049] Step 4: Loosen the fan blade 30 with the fixed chuck 5 and remove the processed fan blade from the fixed chuck 5.

[0050] The utility model has the following advantages: the utility model can automatically complete the processing of the hub end face 30-2, the blade end face 30-4, the outer cavity side wall 30-6, the outer end face 30-7, the inner end face 30-8, and the inner cavity side wall 30-9 on the fan blade 30, and realize the transfer of the workpiece between various workstations through the transfer chuck. No human participation is required during the processing, which greatly improves the processing efficiency and reduces labor costs.

[0051] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
