[0054] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0055] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0056] Example 1: Vertical turning, milling, and boring multi-functional composite machining center, such as Figure 1-7 As shown, the system includes a workbench 1, a tool turret on one side of the workbench 1, a tool magazine 4 on the other side of the workbench 1, an electrically controlled door 5 on one side of the tool magazine 4, and a workpiece positioning mechanism, a cutting fluid output mechanism, and a cutting fluid recovery mechanism on the workbench 1. The workpiece positioning mechanism is used to fix and adjust the position of the workpiece, and works with the tool turret to perform machining operations. The cutting fluid output mechanism is used to output cutting fluid to the workpiece. The cutting fluid recovery mechanism is used to recover the output cutting fluid. A mounting platform 26 is provided in the middle of the workbench 1. The mounting platform 26 has a boss-like structure with an upward bulge in the middle, and an annular cavity is provided between the workbench 1 and the mounting platform 26.

[0057] The cutting fluid recovery mechanism includes:

[0058] An annular filter tank 14, which is slidably connected up and down in the annular cavity. The annular filter tank 14 is provided with evenly distributed filter holes 13.

[0059] A spring 25, the top of the spring 25 is fixed to the outer wall of the bottom of the annular filter tank 14, and the bottom of the spring 25 is fixed to the inner wall of the bottom of the annular cavity.

[0060] A collection chamber 24, which is arranged in the operating table 1. A plurality of leakage ports 23 are provided at the bottom of the annular cavity. The annular cavity is communicated with the collection chamber 24 through the leakage ports 23. The collection chamber 24 is communicated with the pumping end of the cutting fluid output mechanism through the operating table 1.

[0061] By setting the cutting fluid recovery mechanism, the installation platform 26 can be used for diversion, so that the cutting fluid can flow smoothly into the annular filter tank 14, and after being filtered through the filter holes 13, it flows into the collection chamber 24 for convenient recycling.

[0062] For the convenience of processing; as Figure 4-7 shown, the workpiece positioning mechanism includes:

[0063] A fixture seat 18, on which an installation cavity is provided.

[0064] A fixture 42, with a clamping structure 40 arranged inside the fixture 42. The fixture 42 is detachably installed in the installation cavity of the fixture seat 18.

[0065] An angle adjustment component, which is used to adjust the angle of the fixture seat 18.

[0066] By setting the workpiece positioning mechanism, the corresponding fixture 42 can be installed according to requirements, and the fixture 42 is used to position the workpiece.

[0067] For the convenience of outputting cutting fluid; as Figure 7 shown, the inner side of the top of the fixture seat 18 is of a hollow structure. A plurality of liquid spraying heads 41 are fixed to the top of the fixture seat 18. The liquid spraying heads 41 are in a "丿" - shaped structure and are conducted with the inside of the fixture seat 18. A second connector 39 is arranged on one side of the fixture seat 18, which is conducted with the inside of the fixture seat 18. One end of the second connector 39 is detachably installed with the cutting fluid output mechanism; a discharge port 36 is arranged on the side of the fixture seat 18.

[0068] By setting structures such as the liquid spraying heads 41, the cutting fluid can be output based on the cutting fluid output mechanism, discharged from the end of the liquid spraying heads 41 after passing through the inside of the fixture seat 18. Since the liquid spraying heads 41 are located outside the fixture 42, the cutting fluid can be better applied and is not interfered by the movement of the fixture seat 18, improving the reliability.

[0069] To facilitate the recycling of cutting fluid; such as Figure 2 , Figure 7 As shown, the cutting fluid output mechanism includes:

[0070] The cutting fluid tank is integrated into the tool magazine 4. Two pumps are installed in the cutting fluid tank for pumping in and pumping out cutting fluid, respectively. One end of the connecting pipe 7 is connected to the pumping end of one of the pumps.

[0071] Connecting pipe 6, one end of which is connected to the output end of another pumping pump, and a first connector 19 is provided at one end of the connecting pipe 6. The first connector 19 is detachably installed on the second connector 39.

[0072] By setting up a cutting fluid output mechanism, the cutting fluid can be output to the fixture seat 18 through the connecting pipe 6 and the first connector 19 using a pump, so that it can be sprayed out from the spray head 41 to apply the cutting fluid. Since the first connector 19 and the second connector 39 of the fixture seat 18 can be flexibly disassembled and installed, the convenience is improved and the maintenance is easier.

[0073] To facilitate adjustment of the structural angle; such as Figure 6 As shown, the angle adjustment component includes:

[0074] Support frame 32, with an arc-shaped frame 31 fixed to the top of support frame 32;

[0075] The support base 16 and the clamp base 18 are adjustablely mounted on the support base 16. An arc-shaped seat 29 is fixed at the bottom of the support base 16, and the arc-shaped seat 29 slides on the outer wall of the arc-shaped frame 31.

[0076] The slide rail 15 is fixed on both sides of the support frame 32. A threaded rod 33 is rotatably installed in one slide rail 15. A translation drive motor 20 for driving the threaded rod 33 to rotate is installed at the end of the slide rail 15.

[0077] A lever 17 is slidably mounted on the inner wall of the slide rail 15, and two levers 17 are connected by a connecting rod.

[0078] Two ball joints 35 are fixed on both sides of the arc-shaped seat 29 respectively. The ends of the ball joints 35 are spherical structures. The lever 17 is provided with a lifting slide cavity 30 that is adapted to the ball joints 35. The ends of the ball joints 35 are movably installed in the lifting slide cavity 30.

[0079] By setting up structures such as ball head rod 35 and lever 17, the translation drive motor 20 can work to drive the threaded rod 33 to rotate, thereby driving the lever 17 to move within the slide rail 15. When the lever 17 moves, it can push the ball head rod 35, thereby causing the arc seat 29 to move on the arc frame 31. Since the arc frame 31 is an arc structure, it can realize the angle adjustment of the workpiece.

[0080] To further adjust the angle of the machined part; such as Figure 5-7 As shown, the clamp seat 18 is rotatably mounted on the support seat 16 via a shaft; a rotation drive motor 38 is mounted on one side of the outer wall of the support seat 16 via a bracket, and the output end of the rotation drive motor 38 is connected to the shaft of the clamp seat 18 via a gear transmission assembly 37.

[0081] For better filtering; such as Figure 5-7 As shown, a linkage frame 21 is fixed to the top of the annular filter tank 14, and the linkage frames 21 are arranged linearly. A linkage block 28 is fixed to the end of the linkage frame 21. A pushing component is installed on one side of the lever 17, and each linkage block 28 is located on the moving path of the pushing component. A plurality of unblocking rods 22 are fixed to the inner wall of the bottom of the annular cavity. The unblocking rods 22 are located directly below the filter holes 13, and the diameter of the unblocking rods 22 is smaller than the inner diameter of the filter holes 13.

[0082] By setting up structures such as the linkage frame 21 and the unblocking rod 22, the linkage block 28 can be pushed by the pushing component based on the movement of the lever 17, thereby causing the annular filter tank 14 to vibrate up and down. During the process, the unblocking rod 22 is inserted into the filter hole 13 to achieve the unblocking effect.

[0083] To improve reliability; such as Figure 5 , Figure 6 As shown, the pushing component includes a connecting frame 34, which is fixed to the outer wall of one side of the lever 17. A linkage wheel 27 is rotatably mounted on the outer wall of one side of the connecting frame 34 via a shaft. The top surface of the linkage block 28 is an arc surface structure.

[0084] By setting up structures such as the linkage wheel 27, the linkage wheel 27 can press the linkage block 28 when the lever 17 moves. Since the linkage block 28 has an arc surface structure, the smoothness of the movement is ensured.

[0085] For ease of processing; such as Figure 3 As shown, the turret includes:

[0086] The main body of the turret 2 has a control panel 3 on its front side;

[0087] The first translation adjustment mechanism 9 is installed inside the turret body 2, and a mounting base 10 is installed on the first translation adjustment mechanism 9.

[0088] The lifting slide rail 11 is fixed on the mounting base 10. The second translation adjustment mechanism 12 is slidably installed inside the lifting slide rail 11. The mounting base 10 is provided with a lifting drive assembly for driving the second translation adjustment mechanism 12 to move up and down.

[0089] Processing module 8 is installed at one end of the second translation adjustment mechanism 12.

[0090] Example 2: Based on Example 1, this example provides a machining method for a vertical turning, milling, and boring multi-functional composite machining center, which includes the following steps:

[0091] S1: Select the appropriate fixture 42 according to the workpiece;
