[0002] Universal joint forks are generally used on transmission shafts. They are widely used in conjunction with cross shafts. Universal joint forks are U-shaped block structures, including fork feet and mounting heads. Two ear holes with the same axis are opened in the fork feet (such as Figure 2 As shown). According to the design requirements of the universal joint fork, the ear holes need to be machined to meet their design functions. However, the current drilling equipment, such as lathes and drilling machines, have a certain degree of difficulty in clamping the universal joint fork, and the drilling difficulty coefficient is high, the production efficiency is low, and the degree of automation is low, which cannot meet the requirements of mass drilling of universal joint fork ear holes.

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the universal joint fork processing fixture comprises a fuselage base 1, a processing table 2 for processing the universal joint fork is arranged on the right side of the fuselage base 1, a clamping device 3 for clamping the universal joint fork is arranged at the left end of the fuselage base 1, a sliding seat 4 is arranged at the bottom end of the clamping device 3, and the clamping device 3 is moved laterally on the fuselage base 1 through the sliding seat 4, and the clamping device 3 is composed of a fixed base 5, a clamping mechanism 6 and a flipping mechanism 7, and fixed bases 8 are fixedly arranged on both sides of the fixed base 5, and the flipping mechanism 7 includes a driving gear 9, a rotating shaft 10 and a driving motor 11 The motor shaft of the driving motor 11 is connected to the rotating shaft 10, and the rotating shaft 10 extends into the clamping mechanism 6. The two fixing seats 8 are provided with fixing members 12, and the fixing members 12 are provided with a plurality of racks that match the driving gear 9, and the driving gear 9 is meshed with the rack on the fixing member 12. The driving gear 9 is meshed with the rack so that the driving gear 9 rolls on the fixing member 12, thereby rotating the clamping mechanism 6 as a whole. The driving gear 9 is arranged on the rotating shaft 10 and is driven by the driving motor 11 to rotate on the rack, thereby driving the clamping mechanism 6 to flip as a whole.

[0017] To elaborate further, during processing, the yoke to be processed is fixedly placed on the clamping mechanism 6, and the yoke is clamped by the three claws 14 on the clamping mechanism 6. When the yoke is installed, the driving motor 11 drives the driving gear 9 on the rotating shaft 10 to rotate, so that the driving gear 9 rotates on the fixing member 12 meshing therewith, so that the clamping device 3 is flipped, thereby positioning the yoke laterally. After adjustment, the sliding seat 4 moves on the slide rail to move the laterally positioned yoke to the processing table 2, and the positioning portion 16 on the processing table 2 is matched with the hole inside the yoke, and then the yoke can be processed.

[0018] In further details, the clamping mechanism 6 includes a chuck body 13 , three clamping claws 14 and a driving assembly 15 . The three clamping claws 14 are all arranged on the chuck body 13 , and clamp the universal joint fork under the drive of the driving assembly 15 .

[0019] In further detail, a positioning portion 16 for positioning the yoke is provided on the processing table 2, and the positioning portion 16 matches the hole on the yoke. Since the yoke is arranged in a U-shaped structure, the inner end faces of the inner fork legs of the yoke are respectively attached to the upper and lower ends of the positioning portion 16, and the hole in the yoke is connected to the positioning portion 16, so that the yoke is positioned on the processing table 2.

[0020] In further detail, a slide rail assembly 17 is disposed between the slide seat 4 and the body base 1 .

[0021] To be more specific, the clamping mechanism 6 can be rotated 90 degrees by the flipping mechanism 7 .
