Description

Technical Field

[0002] During the production and processing of high-strength bolts, multiple surface treatment processes such as pickling and electroplating are often required to improve the strength and quality of the bolts.

[0003] After searching, the existing patent (Announcement No.: CN216234373U) discloses a high-strength bolt outer surface treatment device. During use, the bolt's movement trajectory can be changed into a W-shaped movement trajectory through the action of the bolt operating mechanism. When the bolt moves to the bottom, the bolt can be pickled, electroplated, and other operations; the corresponding surface treatment operations can be performed while the bolt is moving, greatly improving work efficiency. However, in the process of realizing the present invention, the inventor found that the existing technology has the following problems: When the above-mentioned treatment device performs surface treatment on the high-strength bolt, the bolt is directly transported and immersed in the pickling liquid for pickling treatment. The outer surface of the bolt has a thread groove. For a deep thread groove, when the bolt is immersed in the pickling tank, it will be blocked by bubbles trapped inside the thread groove, and there is a situation where the pickling liquid and the inner wall of the thread groove are not in close contact, which leads to pickling leaks on the bolt surface, reducing the quality of the bolt.
