[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3, A processing device for multi-faceted one-time clamping of a universal joint fork, including a base 10, and a processing frame 11 is provided on the base 10.

[0023] A four-axis rotary table 1 and a four-axis rotary tailstock 2 are respectively provided on the base 10. A central roller 8 is coaxially connected between the four-axis rotary table 1 and the four-axis rotary tailstock 2. On both sides of the central roller 8, there are a plurality of clamping assemblies for clamping a workpiece to be processed 7. A servo motor is provided in the four-axis rotary table 1, and the output shaft of the servo motor is coaxially connected to the central roller 8.

[0024] It can be understood that the four-axis rotary table 1, the four-axis rotary tailstock 2 and the base 10 are integrally designed as the main clamping and control carrier. The servo motor provided in the four-axis rotary table 1 can accurately control the rotation angle of the central roller 8 so as to effectively process different positions of the workpiece to be processed 7.

[0025] Among them, the clamping assembly includes a fixing member 5 and a slider 9. Every two longitudinally arranged fixing members 5 are symmetrically arranged on both sides of the central roller 8. On the opposite sides of every two longitudinally arranged fixing members 5, a counter arm 6 is slidably connected through a slider 9. On the opposite sides of every two longitudinally corresponding counter arms 6, a cover plate 3 is provided. Between every two counter arms 6 provided on the fixing member 5, there is a clamping claw 4 for clamping the workpiece to be processed 7.

[0026] In addition, two vacuum cleaners 13 and dust collection boxes 12 which are symmetrically distributed are provided on the base 10. The air outlet of the vacuum cleaner 13 penetrates through the dust collection box 12 and extends into the interior of the dust collection box 12. A screen is clamped in the dust collection box 12, and a plurality of screen holes are opened on the screen.

[0027] In this embodiment, by setting the vacuum cleaner 13 and the dust collection box 12, the generated debris and sundries during processing can be effectively absorbed and collected, and through the snap-in screen design, the debris and sundries collected in the dust collection box 12 can be effectively cleaned.

[0028] The working principle of this embodiment is as follows:

[0029] Place the fork to be processed 7 between the clamping claws 4 for clamping. After the clamping is completed, start the four-axis rotary table 1 to drive the rotation of the central rotating shaft 8, the processing frame 11 and other structures, and then synchronously drive the fork to be processed 7 to rotate. According to the processing requirements of different hole positions, adjust the rotation angle, and multi-station common processing can be achieved without multiple clamping. After the processing is completed, the generated debris and dust can also be quickly collected into the dust collection box 12 by the vacuum cleaner 13, improving the working environment during work.
