Technical Field

The invention relates to an electroplating conductive hanger, in particular to a clamping opening and closing structure for the electroplating conductive hanger.

Background

The hanging tool is an important part in the shaft hanging plating process. The screw head is a shaft part, and the electroplating of the screw head also adopts a shaft rack plating process. A conventional screw head electroplating conductive hanger is shown in fig. 1a, 1b and 1c, and comprises a transverse frame body 100 and a hanger unit 101, wherein the hanger unit 101 is composed of a cathode mounting hanger 102 for mounting a cathode 108 with a spiral shape on a plane and a shaft clamping hanger 103 for clamping a screw head 109, one end of the cathode mounting hanger 102 is connected with the transverse frame body 100 to make the cathode mounting hanger 102 hang on the transverse frame body 100, the shaft clamping hanger 103 comprises a cylindrical clamping sleeve 104, a locking bolt 105 radially arranged on the cylindrical clamping sleeve 104, and a nut 106 matched with the locking bolt 105, one shaft end of the cylindrical clamping sleeve 104 is connected with the other end of the cathode mounting hanger 102, the upper part of the screw head 109 extends into an inner hole of the cylindrical clamping sleeve 104 from the other shaft end of the cylindrical clamping sleeve 104 when the screw head 109 is clamped, a force is applied to the locking bolt 105 to make the head of the locking bolt 105 and the radial surface of the upper part of the screw head 109 abut against each other shaft end of the screw head 109 and push the upper part of the screw head 109 to make the upper part of the screw head 109 abut against each other shaft end of the cylindrical clamping sleeve 109 The inner hole wall of the clamping sleeve 104 is tightly attached, and the upper part of the screw head 109 is limited between the inner hole wall of the cylindrical clamping sleeve 104 and the head part of the locking bolt 105, so that the clamping of the screw head 109 is realized. The shaft clamping pendant 103 with the structure is of a closed structure, and can meet the basic process requirement of rack plating of the screw head although clamping of the screw head 109 is realized, but has the following problems: 1) in order to adapt the screw head electroplating conductive hanger to screw heads 109 with different sizes, the bore diameter of an inner bore of the cylindrical clamping sleeve 104 is generally designed to be larger, so that when the screw head 109 to be electroplated is smaller in size, the screw head 109 is easily tilted when the screw head 109 is manually clamped, namely the screw head 109 is not parallel to the axis of the cylindrical clamping sleeve 104, and the tilted screw head 109 is easily dropped, which requires a certain skill of an operator, however, even an operator with high skill cannot ensure that the clamping is not tilted every time; 2) after the screw head 109 is fixed, the contact is only the line contact between the upper radial surface of the screw head 109 and the inner hole wall of the cylindrical clamping sleeve 104, and the contact between the head of the locking bolt 105 and the upper radial surface of the screw head 109, that is, the contact surface is only one line, which is not only bad in clamping stability, especially bad in clamping other long-axis parts or heavy-axis parts, but also bad in conductivity because the conductivity is limited to one line, and bad in conductivity.
