This apparatus typically consists of a drum and an electric motor. The workpiece is rotated by the drum, thereby achieving uniform coating coverage. For example, utility model patent CN219808024U discloses a workpiece barrel plating apparatus, including an electroplating tank containing a barrel plating mechanism. A lifting mechanism is located on one side of the electroplating tank. The barrel plating mechanism includes a barrel and a first gear, with the first gear fixedly installed at one end of the barrel. The barrel plating mechanism also includes a fixing plate and a connecting rod. The lifting mechanism includes a cylinder, a sleeve, and a support rod.

[0003] Existing barrel plating equipment, due to the rigid contact between the workpiece and the barrel, may cause scratches and wear on the workpiece surface, reducing the workpiece's lifespan and appearance quality. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant protection device for barrel-plated workpieces, which solves the problem that, in the use of existing barrel plating equipment, the workpiece surface may have scratches and wear due to the hard contact between the workpiece and the drum, thus reducing the service life and appearance quality of the workpiece.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a protective cover to the inner wall of the drum, which can isolate the workpiece from the hard contact between the workpiece and the drum, thereby minimizing the probability of wear and scratches on the workpiece during the drum plating process, and improving the quality and uniformity of the coating.

[0013] 2. This utility model provides a cleaning mechanism at the opening of the drum. The rotating shaft is turned by a knob, and then the two threaded shafts are rotated through the transmission between bevel gears.
