Embodiment Construction

[0013] Such as figure 1 As shown, a screw pin for connecting rod assembly provided by the present invention includes a tightening part 1, a non-cooperating part 2, a pin post part 3 and a threaded part 4, and the tightening part 1 is used for tightening and locking the screw pin. Dead, the pin part 3 is matched with the connecting rod screw pin hole, the threaded part 4 is matched with the hex nut 5, and the diameter of the pin part 3 is larger than the diameter of the threaded part 4.

[0014] Compared with ordinary screws, since the pin post part 3 is added in the middle section of the screw pin, the diameter of the pin post part 3 is larger than that of the thread part 4, and the strength of the screw pin is enhanced due to the increase of the cross-sectional area. At the same time, preferably, in order to reduce the transition area 7 between the non-cooperating part 2 and the pin part 3 (ie figure 1 The processing residual stress generated during processing in the middle ...

Abstract

The invention relates to a screw pin for joint assembly of connecting rods. The screw pin comprises a screwing part, a non-mating part, a pin stud part and a thread part, wherein the screwing part is used for tightly screwing the screw pin, the pin stud part is matched with screw pin holes of the connecting rods, the thread part is matched with a hexagonal nut, and the diameter of the pin stud part is larger than that of the thread part. The screw pin for joint assembly of the connecting rods is simple in structure and reasonable in design, provides convenience for joint assembly of the connecting rods, and improves the joint strength and reliability.

Description

technical field [0001] The invention relates to a connecting rod connecting device in the technical field of presses, in particular to a screw pin for connecting rod connecting and assembling. Background technique [0002] In the current assembly of the connecting rod of the press, in order to facilitate the assembly of the connecting rod, the connecting rod is generally designed to be divided into two parts, the upper and lower parts. Affect the accuracy of parts, but also increase double pin or multi-pin positioning. This connection method is the most widely used form at present, but there are many processes during processing, and there are correspondingly many parts for assembly, and the screws and pins are prone to shearing failures. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a new type of connecting rod connecting assembly screw pin with simple structure, reasonable design,...
