Deviation correcting device for abnormal bolt

Abstract

The invention relates to a deviation correcting device for an abnormal bolt, comprising a conveyor part (1) of the abnormal bolt (5) and a guide rail (2). The guide rail (2) on which the abnormal bolt runs is arranged on a stander, the guide rail arranged at one end of a thread rolling part (3) is provided with a righting frame, the righting frame is used for preventing the abnormal bolt (5) from rocking on the guide rail and comprises a left clamping plate (4) and a right clamping plate (4), each clamping plate (4) is an angle plate consisting of a vertical plate (41) and a transverse plate (42), the vertical plates (41) of the two clamp plates (4) are respectively fixed on corresponding side surfaces of the guide rail (2), the transverse plates (42) at the tops of the clamping plates (4) are located above the top surface of the guide rail (2), and the distance (h) between two opposite edges of the left transverse plate (42) and the right transverse plate (43) is equal to or just larger than the diameter (d) of the abnormal bolt (5). The invention has the advantages that: the righting frame is arranged on the guide rail, so the abnormal bolt is just limited in the right frame after the abnormal bolt moves in the righting frame, thereby limiting the transversely rocking of the bolt, preventing the abnormal bolt from entering the thread rolling part at a wrong state, and guarantying the thread rolling quality of the products.

Description

technical field [0001] The invention relates to the technical field of thread rolling machines, in particular to a deviation correcting device for the running position of special-shaped bolts. Background technique [0002] Existing a kind of patent No. is that CN98217653.8 name is called the Chinese utility model patent of " thread rolling machine automatic feeding mechanism " discloses a kind of structure, and its structure is realized by frame, material box, inclined bucket board, material trough guide rail, realizes feeding. The rotating wheel, the control wheel for realizing sequential material guidance, and the driving disc I and driving disc II for driving them to rotate are composed of. The utility model uses the continuous rotation of the rotating wheel to enclose the workpiece and transport it into the guide rail of the trough, and then freely slides down to the thread rolling machine to realize the purpose of automatic feeding. Its structure is simple, the manufac...

Problems solved by technology

But its disadvantage is that this kind of mechanism does not work well for special-shaped bolts. The reason is that special-shaped bolts are generally top-heavy, so when they run forward on the guide rail, they will swing. When the bolt is thread-rolled, oblique threads will appear, that is, it will become an unqualified product, so its structure still needs to be improved.
