Description

Technical Field

[0001] The utility model relates to the technical field of sliding mechanisms, in particular to a sliding mechanism of a heading of a nut cold heading machine. Background Art

[0002] Nuts are nuts, which are parts that are screwed together with bolts or screws to tighten. In the production process of nuts, they need to be processed and produced in batches by cold heading machines. At present, when cold heading machines are used to produce nuts, the sliding mechanism is required to slide the pier head. However, the sliding distance of the pier head driven by the traditional sliding mechanism is limited, and the sliding effect of the pier head is poor.

[0003] In order to improve the sliding effect of the pier head, the utility model with patent publication number CN211101369U discloses a sliding mechanism for the nut cold heading machine, which can drive the screw on the transmission shaft to rotate by controlling the servo motor, so as to drive the nut and the first fixed seat together with the second fixed seat fixed with the heading head to move forward and backward through the threaded structure, thereby ensuring the sliding distance of the heading head. Although it is convenient to improve the sliding effect of the pier head, when the pier head slides, the first fixed seat and the second fixed seat are moved by the cooperation of the screw and the nut. When the pier head processes the nut, the first fixed seat and the second fixed seat are easily slightly displaced on the screw due to the vibration generated during the processing, which will cause partial deviation in the position of the pier head, thereby affecting the stability of the pier head when processing the nut.
