[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Refer to Figures 1-3 As shown: A multi-station turning machining center for shaft parts includes an operating table 2. A switching mechanism is provided on the top of the operating table 2. The switching mechanism includes a switching disk 1, a support frame 3, and a drive assembly 10. The bottom of the drive assembly 10 is fixedly connected to the operating table 2. The output shaft of the drive assembly 10 is fixedly connected to the switching disk 1. An electric push rod 12 is fixedly connected to one side of the drive assembly 10. One end of the electric push rod 12 is fixedly connected to the support frame 3. The bottom of the support frame 3 is slidably connected to the operating table 2. An electric push rod 23 is embedded inside the support frame 3. A limit frame 11 is fixedly connected to the top of the electric push rod 23. The limit frame 11 is slidably connected to the support frame 3, and the top of the limit frame 11 is engaged with the switching disk 1. An auxiliary plate 14 is fixedly connected to one side of the support frame 3. The bottom of the auxiliary plate 14 overlaps with the switching disk 1, and the bottom of the auxiliary plate 14 is engaged with the limit frame 11.

[0020] The drive assembly 10 is fixed on the operating table 2, and its output shaft is directly connected to the switching disk 1. The rotation of the drive assembly 10 drives the switching disk 1 to rotate, realizing the switching of different processing positions. One end of the electric push rod 12 is fixed to the side of the drive assembly 10, and the other end is connected to the support frame 3. It can push the support frame 3 to slide along the operating table 2 to adjust the relative position of the support frame 3 and the switching disk 1. The limit frame 11 slides up along the support frame 3 until the top of the limit frame 11 engages with the switching disk 1. At the same time, the bottom of the auxiliary plate 14 engages with the limit frame 11 to further enhance the locking stability, prevent the switching disk 1 from shaking during processing, and improve the stability of the switching disk 1 during use.

[0021] Example 2: Figures 1-4 As shown, an auxiliary frame 9 is fixedly connected to the top of the switching disk 1. A guide rod cylinder 15 is embedded inside the auxiliary frame 9. A connecting plate 16 is fixedly connected to the bottom of the guide rod cylinder 15. A clamping block 17 is fixedly connected to the bottom of the connecting plate 16. A clamping block 28 is engaged with the bottom of the clamping block 17. The bottom of the clamping block 28 is fixedly connected to the switching disk 1. A placement cavity is formed between the clamping block 17 and the clamping block 28. A sliding rod 19 is slidably connected inside the clamping block 28. An extension block 20 is fixedly connected to one end of the sliding rod 19. The bottom of the extension block 20 is slidably connected to the switching disk 1. A limit bolt 21 is installed between the extension block 20 and the switching disk 1. A support shaft 5 is engaged with the top of the switching disk 1. An installation part 6 is fixedly connected to the outer ring surface of the support shaft 5. A fan 7 is fixedly connected to one side of the installation part 6. A collection box 4 is engaged with the top of the operating table 2. A collection box 28 is provided on one side of the collection box 4. The bottom of the collection box 28 is engaged with the operating table 2.

[0022] The auxiliary frame 9 is fixed on the top of the switching disk 1. The guide rod cylinder 15 inside drives the connecting plate 16 to move up and down, thereby driving the clamping block 17 to rise and fall. When the clamping block 17 descends, it engages with the clamping block 2 18 fixed on the switching disk 1. The placement cavity between the two achieves the clamping of shaft parts. The clamping block 2 18 is slidably connected to the slide rod 19. One end of the slide rod 19 is connected to the extension block 20. When the extension block 20 slides along the surface of the switching disk 1, the slide rod 19 slides along the clamping block 2 18. By adjusting the sliding of the slide rod 19 and the extension block 20, parts of different lengths can be adapted. During processing, the fan 7 generates a directional airflow to blow the chips generated by turning away from the surface of the workpiece. The collection box 1 4 and the collection box 2 8 respectively receive the blown-off chips, thereby preventing the chips from accumulating in the processing area.

[0023] The operating method and working principle of this device are as follows: First, adjust the distance between clamping block 28 and extension block 20 according to the required length of the shaft part to be processed. Then, rotate the limiting bolt 21 so that the end of the limiting bolt 21 connects with the switching disk 1 to limit the extension block 20. Place the part above clamping block 28 and extension block 20. Then, use an external controller to start the guide rod cylinder 15. The guide rod cylinder 15 drives the connecting plate 16 and clamping block 17 to move down. The clamping block 17 presses the part to achieve the limiting. Then, use the drive assembly 10 to drive the switching disk 1 to rotate on top of the drive assembly 10 to realize the part processing. After the workstation is switched, the electric push rod 12 drives the support frame 3 to move closer to the switching plate 1, so that the auxiliary plate 14 overlaps the top of the switching plate 1. Then, the electric push rod 13 drives the limit frame 11 to move upward, so that the top of the limit frame 11 engages with the switching plate 1. At this time, the limit frame 11 and the auxiliary plate 14 are used to limit the switching plate 1. The machine tool drill bit above the operating table 2 can be used to process the parts. The fan 7 can accelerate the air flow around the workpiece and reduce the residue of debris on the surface of the parts. When processing the end of the parts, the debris can be collected in the collection box 2 8 and the collection box 4 respectively.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
