[0013] like Figure 1As shown, this utility model discloses a chamfering processing device for a constant velocity joint long shank fork part, including a base 1. The base 1 is provided with two parallel first guide rails 2, each of which is provided with a first slider 3. The first slider 3 is provided with a first slide block 4. The base 1 is provided with a slide block drive motor 5 and two support seats 6. A lead screw 7 is rotatably connected between the two support seats 6. A nut seat is fixedly connected to the first slide block 4. The nut seat is provided with a threaded hole and is threadedly connected to the lead screw 7 through the threaded hole. The output shaft of the slide block drive motor 5 is fixedly connected to the end of the lead screw 7. A rotary chuck 8 is provided on the first slide block 4. Two first columns 9 are fixedly provided on one side of the rotary chuck 8 on the first slide block 4. A double-rod finger cylinder 10 is fixedly installed on the upper end of the first column 9. The double-rod finger cylinder 10 is located above the rotary chuck 8. The two output ends of the double-rod finger cylinder 10 are respectively connected to a clamping block 11.

[0014] A first grinding mechanism 24 is provided on one side of the first guide rail 2 on the base 1. The first grinding mechanism 24 includes two parallel second guide rails 12. The second guide rails 12 are set on the base 1 and are parallel to the first guide rail 2. Each second guide rail 12 is provided with a second slider 13. A guide rail clamp 14 is provided between the second slider 13 and the second guide rail 12. A second slide block 15 is provided on the second slider 13. A second column 16 is fixedly provided on the second slide block 15. A clamping seat 17 is provided at the upper end of the second column 16. A through hole is provided in the clamping seat 17. The clamping seat 17 is sleeved on the second column 16 through the through hole. An opening 18 is provided on one side of the through hole. The two sides of the opening 18 of the clamping seat 17 are connected by mounting holes 19 and screws. A mounting seat 20 is fixedly connected to the clamping seat 17. A grinding head rotation drive device is provided on the mounting seat 20. The rotation output end of the grinding head rotation drive device is connected to an electric grinding head 21.

[0015] Furthermore, a second grinding mechanism 25 is provided on the base 1 on the other side of the first guide rail 2. The structure of the second grinding mechanism 25 is the same as that of the first grinding mechanism 24.

[0016] Working principle:

[0017] The first grinding mechanism 24 is adjusted to a suitable position along the second guide rail 12 via the second slider 13, locked with the guide rail clamp 14, and the height of the electric grinding head 21 is adjusted via the clamping seat 17. The screws in the mounting hole 19 are tightened and fixed. Then, the lower end of the constant velocity joint long shank fork part 27 is clamped by the rotating chuck 8. The double-rod finger cylinder 10 drives the two clamping blocks 11 to clamp the upper part of the constant velocity joint long shank fork part 27. Then, the slide drive motor 5 drives the first slide 4 to move via the lead screw 7 and nut seat. The first slide 4 drives the constant velocity joint long shank fork part 27 to move closer to the electric grinding head 21 along the first guide rail 2. Then, the rotating chuck 8 drives the constant velocity joint long shank fork part 27 to rotate around its own axis. The grinding head rotation drive device drives the electric grinding head 21 to rotate to the upper edge of the constant velocity joint long shank fork part 27. At the same time, the electric grinding head 21 starts to chamfer the outer edge of the constant velocity joint long shank fork part 27. After the constant velocity joint long shank fork part 27 rotates one revolution, the machining is completed, and the grinding head rotation drive device rotates to drive the electric grinding head 21 away from the constant velocity joint long shank fork part 27. Next, the second grinding mechanism 25 starts and performs chamfering on the inner edge of the constant velocity joint long shank fork part 27 using the same working principle as the first grinding mechanism 24. Then, the rotary chuck 8 stops driving the constant velocity joint long shank fork part 27 to rotate, and the slide drive motor 5 drives the first slide 4 to drive the constant velocity joint long shank fork part 27 back to its original position. After the double-bar finger cylinder 10 and the rotary chuck 8 are released, the constant velocity joint long shank fork part 27 can be removed.

[0018] This invention utilizes a rotating chuck 8 to clamp and drive the constant velocity joint long shank fork part 27 to rotate. The slide drive motor 5 drives the constant velocity joint long shank fork part 27 to adjust its position. Then, the grinding head rotation drive device drives the electric grinding head 21 to perform chamfering on the constant velocity joint long shank fork part 27, thereby replacing the manual hand-grinding method. The clamping is stable, improving processing efficiency and product quality, reducing labor intensity, and reducing safety hazards.

[0019] Furthermore, the rotary chuck 8 is a pneumatic rotary chuck or a hydraulic rotary chuck.

[0020] The rotary chuck 8 includes a rotary mechanism and a three-jaw clamping mechanism. The three-jaw clamping mechanism is used to clamp the workpiece to be processed, and the rotary mechanism is used to drive the three-jaw clamping mechanism to rotate.

[0021] Furthermore, the grinding head rotation drive device includes a grinding head drive cylinder 22 and a rotating seat 23. The grinding head drive cylinder 22 is mounted on the mounting base 20, and the rotating seat 23 is rotatably connected to the mounting base 20. The output shaft of the grinding head drive cylinder 22 is connected to the rotating seat 23 through a transmission mechanism, and the end of the rotating seat 23 is fixedly connected to the electric grinding head 21 through a clamp 26.

[0022] Specifically, the grinding head drive cylinder 22 can be an SDAD dual-axis double-acting cylinder.

[0023] Furthermore, the clamping block 11 is provided with a clamping wheel, which is rotatably connected to the clamping block 11 via a bearing. The clamping wheel can cooperate with the rotation and rolling of the constant velocity joint long shank fork part 27 to reduce wear.

[0024] Specifically, the rotary chuck 8, double-bar finger cylinder 10, guide rail clamp 14, grinding head rotation drive device, electric grinding head 21, clamp 26, and other aspects not described in detail all adopt known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here. For example, the double-bar finger cylinder 10 can be the AirTAC HFT16-40S model.
