Description

Plating rack and its combined clamping fixture

The invention relates to a plating rack and a combination plate clamp thereof; in particular, an innovative structure designer of a plating rack which is composed of metal sheets.

According to the plating technology and procedures of the current electroplating, the workpiece is generally fixed on a plating rack, and the plating rack is placed in a plating tank filled with the plating solution together with the fixed workpiece. The conductive rod on the plating rack is electrically connected to the workpiece, so that the area where the workpiece and the conductive rod are in contact can be electroplated.

Generally, the plating rack structure is mainly composed of a main frame body and at least one sub-frame body. However, in order to increase the productivity of the plating operation, the number of the sub-frames is usually set to plural. The main frame body has a plurality of conductive rods, and the at least one sub-frame body is provided with a plurality of clamps. After the workpieces are clamped by the clamps, the sub-frame body and the main frame body are combined and welded. If the sub-frame that has been fixed by welding needs to be matched with the angle of the workpiece, it must be bent. However, in the process of bending, a certain degree of error will inevitably occur. If the two ends of the same workpiece need to be clamped at the same time, if the angles of the clamps on both sides are not parallel, the error of the angle will be accumulated. Therefore, the yield of the finished product is seriously affected. Therefore, it is necessary to adjust the angle of the clamp one by one while clamping the workpiece. Such a treatment cannot completely solve the lack of the conventional plating hanger. In this way, no matter how precise the front-end machining operation of the sub-frame is, the precision machining operation of the front-end work will be abandoned as soon as it encounters the need to bend the adjustment angle, which is completely inconsistent with economic benefits.

Therefore, in view of the problems existing in the above-mentioned conventional technologies, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.
