TECHNICAL FIELD

[0001] The utility model belongs to aviation chrome plating technical field, concretely relates to an array type plane local chrome plating tool. BACKGROUND

[0002] In the field of chrome plating, in order to realize the wear resistance and sealing of the plane of the part, there are many parts that need to be plated on the plane of the part. In the process of plating such parts, due to the process characteristics of chrome plating, the uniformity of the chrome plating layer is difficult to guarantee.

[0003] At present, there are mainly two methods for local chrome plating of the plane of small parts: one is to fix the parts by binding, and then to insulate the parts that do not need to be plated by using plastic cloth. Due to the instability of manual insulation and binding operation, it is difficult to guarantee the uniformity of the plating layer by this method. The other is to make special clamping mechanisms to clamp the parts, and then to increase auxiliary anodes on the chrome plating plane. Such clamps can solve the problem of uniformity of the plating layer, but the loading capacity of each slot is small, generally 1 to 2 parts, and the production efficiency is low.

[0004] The prior art CN106435702 discloses a "part plane chrome plating device and method", which fixes the parts by movable components. The clamping method is complex, the parts are numerous, and it is not easy to operate. Only two parts can be clamped in parallel.

[0005] The prior art CN218203120 discloses a "plane type chrome plating process device", which is connected by a main shaft and fixed by an iron sheet. The device is composed of multiple parts and is inconvenient to operate. Only two parts are arranged vertically, and the efficiency is low. UTILITY MODEL CONTENTS

[0009] Further, one end of the copper hook is connected with a conductive rod at the end of the connecting groove, and the other end is welded with the metal main shaft.

[0010] Further, the copper hook is a square copper hook.

[0011] Further, the sleeve has eight, every two form a sleeve group, the sleeve group is welded on the metal main shaft at equal intervals.

[0012] Further, the sleeve is made of stainless steel material.

[0013] Further, the threaded hole in the side surface of the sleeve cooperates with the screw to fix the part.

[0014] Further, the screw is made of polytetrafluoroethylene material.

[0015] Advantages

[0016] The tool provided by the utility model has a cathode protection sleeve made of stainless steel as a main body, and parts are positioned at the center of the sleeve through sleeve limiting parts, and only the chrome-plated plane of the parts is exposed, so that the instability of artificial insulation parts and the time-consuming problem of insulation operation are avoided.

[0017] The sleeve is made of stainless steel and is connected with the chrome-plated plane of the parts, the chrome-plated edge is expanded, and the uneven phenomenon of the plating layer caused by the sharp end discharge phenomenon of the parts is avoided. Meanwhile, the eight sleeves are connected with the main shaft in an array mode, and the parts are fixed through screws, so that one set of tool can clamp eight parts, the problem of small loading capacity of the chrome-plated plane of the parts is solved, the clamping of the parts is fast, and the positioning is accurate. The tool is widely applied in the factory and has achieved good effects. BRIEF DESCRIPTION OF DRAWINGS
