Problems solved by technology

[0002] In the prior art, when the electroplating of discontinuous multi-section inner holes is involved, the method of staged electroplating or manual tape protection is usually adopted. The electroplating cycle is long, manual protection is difficult, and the uniformity of the coating is poor, and the chrome plating transition area (edge ​​area) is not good. Specification (poor quality) and other issues, low pass rate of chrome plating

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] see Figure 1-10 , the workpiece 10 includes four inner holes: the first inner hole 101, the second inner hole 102, the third inner hole 103 and the fourth inner hole 104, and the first inner hole 101 and the third inner hole The hole 103 is electroplated (the electroplating part of the inner hole), and the inner hole 102 of the second section is not electroplated (the non-electroplating part of the inner hole) as an example. The inner hole electroplating device of the present invention includes an anode rod 7 and a protective sleeve 2 sleeved on the anode rod 7, the second section inner hole 102 of the workpiece 10 is sleeved on the protective sleeve 2, and the anode rod 7 is located on the In the inner hole of the workpiece 10, and there is a gap between the first section of the inner hole 101 and the third section of the inner hole 103 and the anod...

Abstract

The invention discloses an inner hole electroplating device. The inner hole electroplating device comprises an anode rod and a protective sleeve, wherein the protective sleeve is arranged on the anoderod in a sleeving manner; a workpiece is arranged on the anode rod and the protective sleeve in a sleeving manner; the protective sleeve is arranged corresponding to the non-electroplated sections ofan inner hole in the workpiece; a gap is formed between the electroplated sections of the inner hole in the workpiece and the anode rod; a metal lining is arranged at the other end of the outer surface of the protective sleeve; a first gasket and a second gasket which are arranged with metal nuts in an overlapping manner are arranged at one end of the anode rod; the first gasket is made of a metal material; the second gasket is made of an insulating material; and the first gasket and the metal lining exert the cathode protective function in the electroplating process. By adoption of the innerhole electroplating device disclosed by the invention, a plurality of discontinuous sections of the inner hole can be electroplated at a time, thereby shortening the electroplating time; the thickness of an electroplated layer is uniform and consistent, thereby lowering the consumption of an electroplating material; and the edge quality of the electroplated layer is improved.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to an inner hole electroplating device. Background technique [0002] In the prior art, when the electroplating of discontinuous multi-section inner holes is involved, the method of staged electroplating or manual tape protection is usually adopted. The electroplating cycle is long, manual protection is difficult, and the uniformity of the coating is poor, and the chrome plating transition area (edge ​​area) is not good. Specification (poor quality) and other issues, low pass rate of chrome plating. Therefore, it is necessary to design a stable and practical process device in the electroplating process to realize the electroplating of discontinuous multi-section inner holes, so that the coating needs to be evenly deposited on the inner holes of the workpiece to ensure the quality of the coating. Contents of the invention [0003] Aiming at the technical problems existi...
