Embodiment Construction

[0017] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] This embodiment proposes a sleeve electroplating protection tooling, its structure is as follows figure 2 shown. The sleeve electroplating protective tooling is made of nylon 66 material, and its weight is 1 / 7 of the iron tooling. Nylon 66 has a breaking elongation rate of 80% and good elasticity, which can reduce the impact with the sleeve during use, and be tightly combined with the sleeve to achieve the sealing effect.

[0019] The electroplating protective tooling includes a Φ12mm rod and two protective plugs. One of the protective plugs is located at the lower end of the rod and has an integrated structure with the rod, and the other protective plug is connected to the rod through the M12 thread at the up...

Abstract

The invention provides a sleeve electroplating protection tool which comprises a rod part and two protection plugs. One of the protection plugs is located at the lower end of the rod part and forms anintegral structure with the rod part, and the other protection plug is in threaded connection with the upper end of the rod part. Conical design is adopted on the contact face of each protection plugand the sleeve. By means of the protection tool, effective inner protection of a sleeve can be achieved, and defects caused by the collision between metal are avoided. Compared with other protectionadhesive tape and protection films, fast demounting can be achieved, and the problems of difficult operation of adhesive tape sticking of the inner surface and hard cleaning are avoided. It is verified through tests that the protection requirement for electrogalvanizing of the outer surface of the sleeve can be effectively met, and the functions of conducting fast demounting and effectively protecting the inner surface are achieved.

Description

technical field [0001] The invention belongs to the technical field of electroplating processing, and in particular relates to a sleeve electroplating protection tool used for internal sealing protection during sleeve electroplating. Background technique [0002] The door shaft sleeve used in a certain type of product has a structure such as figure 1 As shown, the sleeve has a through-hole structure, the diameters of the upper and lower ports are different, and there is no thread. The dimensional accuracy of the inner diameter of the sleeve is 0.005, and the outer surface is required to be galvanized. Due to the high accuracy of the inner diameter, it is necessary to strictly protect the inner surface of the sleeve during the electroplating process, and to avoid corrosion of the inner surface due to pickling and other processes during the electroplating process. [0003] Partial protection of electroplating usually adopts methods such as silica gel protection plug, protect...
