Description

Copper plating device and copper plating method for outer diameter of special-shaped ferrule Technical Field The invention relates to the technical field of bearing ring surface treatment, in particular to a copper plating device and a copper plating method for an outer diameter of a special-shaped ring. Background In the bearing ring processing field, when copper plating is carried out on the outer diameter of the special-shaped ring, various groove liquids are required to be strictly prevented from contacting the inner diameter (non-copper plating surface) so as to avoid chemical corrosion of the groove liquids on the inner diameter (non-copper plating surface). Two symmetrical bosses are arranged on the upper end face of the collar, and the bosses are higher than the horizontal plane. The existing processing modes of the traditional protection method mainly comprise two modes. Firstly, a special sealing ring is needed to be customized, and a rubber gasket with proper size is placed at the special-shaped part to protect the inner diameter (not copper plating surface). However, this operation is difficult to seal, and it is difficult to achieve 100% sealing. The dead weight of the bearing ring is not light, and is generally about 10KG, and the production site is completely manually operated, so that the tightness is required to be tested by repeatedly entering water. Products with different sizes and different structures need to be customized with special sealing rings, and in actual production, the special-shaped products have multiple types, small batch and high manufacturing cost. And secondly, a sealing method is to integrally glue the inner diameter (non-copper plating surface) of the bearing ring to be protected. However, the sealing method cannot be formed at one time, the sealing uniformity is required to be adjusted by coating for multiple times, the sealing requirement can be met by repeated drying, the whole sealing operation period of a single product at least needs 8 working hours, the glue has heavy smell and is in a peculiar smell sealing environment for a long time, the body health of operators is seriously damaged, and the operators commonly have contradicting heart states. After the copper electroplating is finished, the inner diameter (non-copper-plated surface) sealing adhesive layer is also required to be stripped. The sealing method has the problems of long processing period, high difficulty, high production cost and low efficiency, and can not meet the requirement of mass production of products. How to design a structure ingenious, simple and practical guarantees sealed effect, reduces the adjustment number of times, reduces intensity of labour simultaneously, realizes lasso copper plating process high efficiency, convenient, low strength operation, promotes production efficiency in order to satisfy the technical problem that mass production required a dysmorphism lasso external diameter coppering device and copper plating method need to solve now in the moment when guaranteeing product quality. Disclosure of Invention Aiming at the problems, the invention provides the copper plating device and the copper plating method for the outer diameter of the special-shaped ferrule, which are ingenious in structure, simple and practical, ensure the sealing effect, reduce the adjustment times, reduce the labor intensity, realize the efficient, convenient and low-strength operation of the copper plating process of the ferrule, ensure the quality of products and simultaneously improve the production efficiency so as to meet the requirement of mass production. The invention adopts the following technical scheme: The copper plating device for the outer diameter of the special-shaped ferrule comprises a fastening bolt piece, a gland and a base, wherein a space for placing the special-shaped ferrule is reserved between the gland and the base, the upper end of the base is provided with a round table for placing the special-shaped ferrule, the outer diameter of the round table is consistent with that of the special-shaped ferrule, the center of the round table is provided with a center screw hole matched with the fastening bolt piece, the center of the lower end of the base is provided with an outwards protruding boss, a blind hole communicated with the center screw hole is formed in the boss, and a rod head of the fastening bolt piece is screwed into and screwed into the blind hole from the center screw hole on the gland to firmly fix the two special-shaped ferrules which are stacked back to back in the middle. The special-shaped ferrule comprises two special-shaped ferrules with the same shape and size, the special-shaped ferrules are of a circular ring structure, the two special-shaped ferrules are stacked back to form a hollow inner cavity for water injection, two symmetrical and outwards-protruding portions are arranged on the special-shaped ferrules in the coaxial direction of the circle center,
