[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0028] Please see Figures 1 to 3 This disclosure provides a complex curved surface machining equipment, which can be used to machine engine blades and other complex curved surface parts, which will not be described in detail here. The complex curved surface machining equipment includes a frame 10, an X-axis moving mechanism 21, a Y-axis moving mechanism 22, a Z-axis moving mechanism 23, an A-axis rotary table 31, a B-axis rotary table 32, a gearbox 41, and a fixture 42. The X-axis moving mechanism 21 is mounted on the frame 10. The Y-axis moving mechanism 22 is mounted on the X-axis moving mechanism 21. The Z-axis moving mechanism 23 is mounted on the Y-axis moving mechanism 22. The X, Y, and Z axes are perpendicular to each other. Specifically, as shown... Figure 2 As shown, the X direction can be the left or right direction of rack 10, corresponding to... Figure 1 It should be the front-to-back direction of rack 10. For example... Figure 1As shown, the Y direction is the left-right direction of the frame 10, and the Z direction is the up-down direction of the frame 10. The A-axis rotary table 31 is mounted on the Z-axis moving mechanism 23 and is used to connect to the grinding wheel (not shown in the figure). The axis of the rotating disk of the A-axis rotary table 31 is in the X direction. The C-axis rotary table 32 is mounted on the frame 10, and the axis of the rotating disk of the C-axis rotary table 32 is in the Z direction. The gearbox 41 is mounted on the C-axis rotary table 32. The fixture 42 is mounted on the output shaft of the gearbox 41. The axis of the output shaft of the gearbox 41 can be named the B-axis, and the direction of the B-axis is in the Y direction. The fixture 42 is used to hold the workpiece to be processed (not shown in the figure). The A-axis rotary table 31, B-axis rotary table 32, gearbox 41, and fixture 42 are all prior art and will not be described in detail here.

[0029] Understandably, high-precision machining of the workpiece is achieved through the coordinated operation of a series of vertically intersecting moving and rotating mechanisms. Specifically, the coordinated movement of the X-axis moving mechanism 21, the Y-axis moving mechanism 22, and the Z-axis moving mechanism 23 enables fine-tuning and positioning of the workpiece in three-dimensional space; the rotation of the A-axis rotary table 31 allows the grinding wheel to rotate along the X-axis, thus enabling flexible adjustment of the grinding wheel's machining direction; the rotation of the C-axis rotary table 32 allows the workpiece to rotate and reposition in the Z-axis, facilitating machining from different angles; furthermore, power is transmitted to the fixture 42 through the gearbox 41, ensuring stable clamping of the workpiece during machining and guaranteeing machining accuracy. The entire workflow begins by clamping the workpiece onto the fixture 42. Then, the workpiece is precisely positioned to the machining location using the X, Y, and Z-axis moving mechanisms. Next, the machining angle between the grinding wheel and the workpiece is adjusted by the A-axis rotary table 31. Then, the workpiece's posture is changed by the C-axis rotary table 32 and the gearbox 41. Finally, the grinding wheel is started for machining. Throughout the process, various mechanisms work closely together to ensure machining efficiency and accuracy, while reducing the labor intensity of workers.

[0030] In one implementation, please refer to Figures 1 to 3The X-axis moving mechanism 21, Y-axis moving mechanism 22, and Z-axis moving mechanism 23 each include a motor 231, a lead screw 232, a slider 233, and two guide rails 234. The lead screw 232 is connected to the motor 231, and the slider 233 is sleeved on the lead screw 232 and threadedly connected to it. The two sides of the slider 233 are slidably connected to the two guide rails 234. This complex surface machining equipment achieves precise three-dimensional spatial movement through the X, Y, and Z-axis moving mechanisms 23, ensuring the flexibility and accuracy of the machining process. During operation, the motor 231 drives the lead screw 232 to rotate, causing the slider 233, which is threadedly connected to the lead screw 232, to move along the lead screw 232. The two sides of the slider 233 are guided by the two guide rails 234, ensuring that the slider 233 moves smoothly on a straight track. Thus, the X, Y, and Z-axis moving mechanisms 23 work together to enable the machining head to move precisely and flexibly in three-dimensional space, thereby efficiently machining complex surfaces.

[0031] In one implementation, please refer to Figure 1 A nut is installed on the slider 233, and the slider 233 is connected to the lead screw 232 through the nut. The nut is sleeved on the lead screw 232 and is threadedly connected to the lead screw 232 to prevent wear of the slider 233.

[0032] In one implementation, please refer to Figure 1 A clamping mechanism 50 is also installed on the C-axis rotary table 32. The clamping mechanism 50 and the fixture 42 are respectively located on both sides of the workpiece to be processed. The clamping mechanism 50 includes a top seat, a slide rail, a lead screw, and a servo motor. The servo motor is connected to the lead screw, the top seat is sleeved on the lead screw and threadedly connected to the lead screw, and the top seat is slidably connected to the slide rail. By installing the clamping mechanism on the C-axis rotary table, precise clamping of both sides of the workpiece is achieved. This clamping mechanism includes a top seat, a slide rail, a lead screw, and a servo motor. The servo motor drives the lead screw to rotate, causing the top seat to move up and down along the lead screw to the appropriate position. Then, the slide rail enables the top seat to slide laterally, thereby reliably clamping the fixture and the workpiece to be processed located on both sides of the C-axis rotary table, ensuring the stability of the workpiece during processing and preventing displacement or loosening during the processing of complex curved surfaces. By precisely controlling the angle and movement distance of the servo motor, it can adapt to workpieces of different sizes and shapes, thereby improving processing efficiency and processing quality. In terms of working principle, the lead screw is first driven to rotate by a servo motor, and the top seat moves laterally along the slide rail to the workpiece position. Then, the pressure of the top seat causes the clamping force on the fixture and the workpiece to act on it, thereby achieving the effect of synchronous clamping on both sides and ensuring the stability of the workpiece throughout the entire processing process.

[0033] In one implementation, please refer to Figure 1 and Figure 2The complex curved surface machining equipment also includes a dual electric spindle 60, which is used to mount grinding wheels. The A-axis rotary table 31 is connected to the grinding wheels via the dual electric spindle 60. When machining the main body of a complex curved surface, the dual electric spindle 60 can be used to mount the sanding belt; when grinding details, it can be used to mount the grinding wheel. This equipment integrates the sanding belt and grinding wheel into the same machine. By changing the sanding belt and grinding wheel and through five-axis linkage interpolation, the entire blade profile, including the R-angle and damping table, can be ground, improving blade machining efficiency. It also enables production line integration and compatibility with various workpiece types, thus achieving production line integration and flexibility.

[0034] In one implementation, please refer to Figure 2 and Figure 3 The complex curved surface machining equipment also includes a tool magazine 70. Users can control the dual electric spindles 60 to move to the tool magazine 70 through the automatic control system to achieve automatic tool changing.
