With the continuous progress of technology, the application of mechanical equipment is gradually promoted, such as various vehicles, agricultural machinery, processing robots and the like, so that people can more conveniently live and work through the use of mechanized and automatic equipment, and various connecting pieces are indispensable in various mechanical equipment, such as connecting forks, shaft rods, plate members and the like.

The conventional connecting fork forge piece structure (simply called a connecting fork) is generally in a shape that one end of the connecting fork is approximately Y-shaped, and the other end of the connecting fork is in an opening state, namely, the connecting fork is connected with an external shaft rod through a cylindrical body part, the fork part at the opening part is connected with an external pin rod, and when the external shaft rod moves or rotates, the shaft rod can drive the pin rod to synchronously move through the connecting fork, so that power transmission is realized.

However, when the technology is used, the fork part of the connecting fork made of the conventional material is in an opening state, so that the fork part is easy to deform and bend when the torque born in the power transmission process is large, and the strength of the conventional Y-shaped connecting fork is required to be improved; therefore, in order to solve the above technical problems, we propose a novel connecting fork forging structure.

Example 2

Referring to fig. 1 to 4, in the case where the other portions are the same as in embodiment 1, this embodiment differs from embodiment 1 in that:

the two sides of the body part 1, which are close to one end of the spline groove 2, are fixedly connected with lugs 8, the middle part of the lugs 8 and the middle part of the spline groove 2 are jointly provided with displacement grooves 9, the two ends of each displacement groove 9 are provided with corresponding bolt holes 10 for installing bolts, and the arrangement of each displacement groove 9 ensures that after the personnel bolt holes 10 are internally meshed with bolts, the lugs 8 and the body part 1 positioned at the upper side and the lower side of each displacement groove 9 are mutually close along with the rotation of the bolts, and the body part 1 which is mutually close clamps the end parts of shaft rods in the spline groove 2, so that the body part 1 is relatively firm in installation with the shaft rods outside; the inner wall of the hole with the bolt hole 10 above the displacement groove 9 is a smooth inner wall, and the inner wall of the hole with the bolt hole 10 below the displacement groove 9 is provided with matched threads corresponding to the bolt, and the inner wall of the bolt hole 10 above the displacement groove 9 is a smooth inner wall, so that when the bolt fixes the body part 1, the body parts 1 are positioned on the upper side and the lower side of the displacement groove 9 and are close to each other, and the clamping and the fixing of the shaft rod inside the spline groove 2 are facilitated.

The inner ring surfaces of the penetrating holes 7 are smooth surfaces, and the two penetrating holes 7 are coaxial, so that when an external pin rod is arranged in the two penetrating holes 7, the abrasion between the outer ring surfaces of the pin rod and the inner wall of the penetrating holes 7 is smaller, the phenomenon that the service life of the pin rod or a connecting fork is abnormally attenuated due to quicker abrasion can be avoided, and the two penetrating holes 7 are coaxial, so that the inner walls of the two penetrating holes 7 are relatively attached when the inner walls of the two penetrating holes 7 are contacted with the outer ring surfaces of the pin rod, namely, the abrasion speed between the pin rod and the penetrating holes 7 is further reduced; the inside that the cylinder portion 5 kept away from connector 4 one end is equipped with ball groove 11, and the outer anchor face of cylinder portion 5 is smooth surface, and ball groove 11's setting can reduce the holistic weight of fork.
