Electroplating processing device for inner bore and end faces of workpiece

Abstract

The invention provides an electroplating processing device for an inner bore and end faces of a workpiece. The inner bore is formed in the processed workpiece in the length direction; a processing device includes an anode bar, and the axis direction of the anode bar is defined as a first direction; the processing device further includes a fastening structure, and a first anode plate, a first fixing piece, a second fixing piece and a second anode plate which are sequentially arranged on the anode rod in a sleeving manner in the first direction; the first fixing piece and the second fixing pieceare arranged at an interval; a first through hole is formed in the first fixing piece; and when the processed workpiece is arranged on the anode bar in a sleeving manner and is contained in a first space, the inner wall face of the first through hole is located at the outer side of the boundary of the inner bore in a first end face, and a gap is present between the first anode plate and the firstend face as well as between the second anode plate and a second end face. The electroplating processing device can change the distribution of power lines in the electroplating process of the workpiece, and thus, uniform distribution of the current density of the electroplated surface of the workpiece is promoted, plating is evenly deposited on the surface of the workpiece, so that chromium plating of multiple parts of the inner bore and the end faces is completed at a time.

Description

technical field [0001] The invention belongs to the field of special process processing methods, can be applied to the processing of holes and multi-position electroplating workpieces on end faces, and relates to a one-time electroplating processing device for inner holes and multi-position end faces. Background technique [0002] The electroplating device is an important fixture for electroplating production. Such as figure 1 (a), figure 1 As shown in (b), for the workpiece 10 to be processed, the inner hole 100 (the part of ΦX) and the two end surfaces (the part of ΦY of the first end surface 1001 and the part of ΦY of the second end surface 1002 ) need to be electroplated. For this kind of chrome-plated workpiece with multiple parts on the inner hole and end face, the traditional method is to protect it by staged electroplating or manually pasting electroplating tapes. The electroplating cycle is long, manual protection is complicated, and the qualified rate of electrop...
