[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1

[0025] like Figures 1-3 As shown, a multi-station valve drilling and tapping composite machine includes a base 1, a processing platform 11 fixedly connected to the top of the base 1, a trapezoidal plate 12 fixedly connected to one side of the middle of the processing platform 11, multiple sets of placement plates 13 fixedly connected to the other side of the processing platform 11, a flipping component provided on one side of the middle of the processing platform 11, and a support component provided in the middle of the processing platform 11.

[0026] The flipping assembly includes a servo motor 2 and a limiting groove 24. The servo motor 2 is installed on one side of the processing platform 11. A lead screw 21 is fixedly connected to the output end of the servo motor 2. A threaded sleeve 22 is threadedly connected to the middle of the lead screw 21. A limiting rod 23 is fixedly connected to the bottom of the threaded sleeve 22. The limiting groove 24 is opened on one side of the processing platform 11. The two sides of the limiting rod 23 and the limiting groove 24 fit together. An L-shaped connecting post 25 is fixedly connected to the top of the threaded sleeve 22.

[0027] The flipping assembly also includes a hollow sleeve 3, which is fixed to one end of an L-shaped connecting post 25. A Y-shaped connecting post 31 is rotatably connected to the middle of the hollow sleeve 3, and a semi-circular groove is provided in the middle of the Y-shaped connecting post 31. Both ends of the forked Y-shaped connecting post 31 are fixed with connecting rings 32, and a dual-axis motor 33 is installed in the middle of each connecting ring 32. Drill bits 34 are installed at the upper and lower output ends of the dual-axis motor 33.

[0028] The flipping assembly also includes a gear 41, two sets of limiting plates 42 and a rack plate 43. The gear 41 is fixed to one end of the Y-shaped connecting post 31. The two limiting plates 42 are respectively fixed to both sides of the trapezoidal plate 12, and the semi-circular groove in the middle of the Y-shaped connecting post 31 fits against the top of the limiting plate 42. The rack plate 43 is fixed to the middle of the trapezoidal plate 12.

[0029] During operation, when valves need to be processed, two sets of valves can be placed on two sets of placement plates 13 near the servo motor 2. Then, the dual-axis motor 33 is driven to run near the output end of the processing platform 11, thereby driving the drill bit 34 to complete the valve processing. After the dual-axis motor 33 has been running for a period of time, the two sets of valves to be processed can be placed on two sets of placement plates 13 away from the servo motor 2. Then, the servo motor 2 is driven to run, thereby driving the lead screw 21 to rotate. The rotation of the lead screw 21 will drive the threaded sleeve 22, the limiting rod 23, and the L-shaped connecting column 25 to move synchronously. With the cooperation of the limiting rod 23 and the limiting groove 24, the movement trajectory of the threaded sleeve 22 can be restricted, thereby causing the threaded sleeve 22 to drive the L-shaped connecting column 25 to move linearly. When the L-shaped connecting column 25 moves, it will drive the hollow sleeve 3 and the Y-shaped connecting column 31. The connecting ring 32 and the dual-axis motor 33 move synchronously. When the Y-shaped connecting column 31 moves to a certain position, the semi-circular groove in its middle will disengage from the limiting plate 42, and the gear 41 will mesh with the rack plate 43. As a result, the Y-shaped connecting column 31, due to the lack of restraint, will drive the dual-axis motor 33 and the drill bit 34 to rotate in the middle of the hollow sleeve 3 under the action of thrust. When the Y-shaped connecting column 31 moves to another set of limiting plates 42, the rack plate 43 and the gear 41 will disengage, and at the same time, the semi-circular groove in the middle of the Y-shaped connecting column 31 will be stuck in another set of limiting plates 42, thereby restricting the Y-shaped connecting column 31 again and preventing it from rotating. At the same time, the Y-shaped connecting column 31 will rotate 180 degrees during the movement, thereby causing the dual-axis motor 33 to rotate half a revolution, causing the drill bit 34 at both ends of the dual-axis motor 33 to change its vertical position, thereby causing the two sets of drill bits 34 to work alternately.

[0030] This step, by reversing the component settings, can reduce the overheating phenomenon that the drill bit 34 is prone to during long-term continuous operation. Overheating not only easily leads to a decrease in the hardness and wear resistance of the drill bit 34, thus affecting the drilling accuracy and surface quality, but may also accelerate the wear of the drill bit 34 and shorten its service life. In addition, overheating of the drill bit 34 may also cause thermal deformation of the material, increase processing errors, and in some extreme cases, may even cause the drill bit 34 to break, affecting the continuous and stable operation of the production line.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the support assembly includes two sets of first support columns 5. Both first support columns 5 are fixed to the middle of the processing platform 11. The top of the two first support columns 5 is fixed with a slotted plate 51. The upper and lower sides of the inner circle of the slotted plate 51 are provided with rectangular slots 52.

[0033] The support assembly also includes multiple sets of rotating shafts 6, which are rotatably connected to both sides of the rectangular groove 52, and ball bearings 61 are fixedly connected to the middle of each of the multiple rotating shafts 6.

[0034] During operation, the first support column 5 and the slot plate 51 support the Y-shaped connecting column 31. When the Y-shaped connecting column 31 moves, it slides in the middle of the slot plate 51. At the same time, it rubs against the ball 61 and generates frictional force. Under the action of friction, the ball 61 and the rotating shaft 6 can be pushed to rotate in the middle of the rectangular slot 52, thereby reducing the resistance between the Y-shaped connecting column 31 and the slot plate 51.

[0035] This step, through the support component, can provide a certain support force for the Y-shaped connecting column 31, thereby improving the stability of the Y-shaped connecting column 31. At the same time, it can also reduce the resistance between the Y-shaped connecting column 31 and the slot plate 51 when the Y-shaped connecting column 31 moves, thereby improving the smoothness of its movement.

[0036] Example 3

[0037] like Figure 1 , Figure 2 As shown, a second support column 7 is fixedly connected to one corner of the top of the processing platform 11. A hollow ring 71 is fixedly connected to the top of the second support column 7, and one end of the lead screw 21 is rotatably connected to the middle of the hollow ring 71.

[0038] During operation, the second support column 7 supports the hollow ring 71. When the lead screw 21 rotates, the end of it that is away from the servo motor 2 will rotate in the middle of the hollow ring 71. This step, through the cooperation of the second support column 7 and the hollow ring 71, can play a role in supporting the lead screw 21, thereby improving the stability and reliability of the lead screw 21.
