[0025] The utility model makes further detailed description in combination with the drawings, so that the person skilled in the art can implement according to the description text.

[0026] As Figures 1-4 The utility model provides a lower conductive piston rod electroplating hanger, it includes: conductive copper bar 110, conductive vertical rod 120, conductive cross rod 130 and conductive sleeve 140.

[0027] The conductive vertical rod 120 is vertically arranged, and the upper end of the conductive vertical rod 120 is fixedly connected to the conductive copper bar 110. In this embodiment, the conductive copper bar 110 is in the shape of a long strip, and the conductive vertical rod 120 is also in the shape of a long strip. The length of the conductive vertical rod 120 is greater than the length of the conductive copper bar 110. The conductive vertical rod 120 is stacked on the outer side of the conductive copper bar 110 along the length direction of the conductive copper bar 110, and the upper end of the conductive vertical rod 120 is provided with a bolt hole 121. The conductive vertical rod 120 is fixedly connected to the conductive copper bar 110 by means of bolts.

[0028] A plurality of conductive horizontal rods 130 are arranged on the conductive vertical rod 120 along the length direction (vertical direction) of the conductive vertical rod 120, and the conductive horizontal rods 130 are arranged close to the lower end of the conductive vertical rod 120. The conductive horizontal rods 130 are perpendicular to the conductive vertical rod 120, that is, the conductive horizontal rods 130 are horizontally arranged. In this embodiment, the conductive horizontal rods 130 are in the shape of long strips.

[0029] A plurality of conductive sleeves 140 are arranged on the conductive horizontal rods 130 along the length direction of the conductive horizontal rods 130. The axis direction of the conductive sleeves 140 is parallel to the conductive vertical rod 120, that is, the axis of the conductive sleeves 140 is arranged along the vertical direction. One end (the upper end of the conductive sleeve 140) of the conductive sleeve 140 facing the conductive copper bar 110 is provided with an opening for inserting the piston rod to be electroplated.

[0030] The vertically arranged conductive sleeve 140 can ensure that the piston rod is in a vertical state during the electroplating process, so that the taper of the electroplated piston rod can be controlled to be 0.02. If the piston rod is inclined, the electroplated taper will increase, which will affect the size of the piston rod.

[0031] As a preferred embodiment, the conductive sleeve 140 is a hollow circular tube. One end (the lower end of the conductive sleeve 140) of the conductive sleeve 140, which is away from the conductive copper bar 110, is fixedly connected to the conductive horizontal rod 130, so that the bottom (the opening) of the conductive sleeve 140 is closed by the conductive horizontal rod 130. A cylindrical recess 141 is formed in the conductive sleeve 140, and the inner diameter of the recess 141 matches the outer diameter of the piston rod, so that the piston rod cannot shake greatly in the recess 141.

[0032] In this embodiment, all the conductive horizontal rods 130 are parallel, that is, the axes of the conductive horizontal rods 130 are located on the same plane, so as to avoid interference with the electroplating hangers of adjacent electroplating stations when the electroplating hangers are used.

[0033] The distance between two adjacent conductive horizontal rods 130 is greater than the length of the piston rod, so that the piston rod can be smoothly placed in the conductive sleeve 140 without colliding with the upper conductive horizontal rod 130.

[0034] As a further preferred, the pipe wall of the conductive sleeve 140 is provided with a tapping hole near the opening end, and a nut 142 is coaxially fixedly connected outside the tapping hole for mounting a tapping screw.

[0035] In the embodiment, the conductive horizontal rod 130 is fixedly connected at the center of the conductive vertical rod 120, and the number of the conductive sleeve 140 on the conductive horizontal rod 130 is the same and the intervals are equal, so that the whole electroplating hanger is in an axial symmetry structure, ensuring the balance and position stability of the electroplating hanger during electroplating.

[0036] As a further preferred, the pipe wall of the conductive sleeve 140 is provided with a tapping hole near the opening end, and a nut 142 is coaxially fixedly connected outside the tapping hole for mounting a tapping screw.

[0037] In the embodiment, the conductive copper bar 110 is bent to form a first hook portion 111 at the upper end, and the conductive vertical rod 120 is bent to form a second hook portion 122 at the upper end, the second hook portion 122 is bypassed from the top of the first hook portion 111 and is arranged outside the first hook portion 111 in a ring shape, and the inner surface of the second hook portion 122 abuts against the outer surface of the first hook portion 111. A nut 123 is welded outside the second hook portion 122, and a bolt hole is coaxially provided at the position corresponding to the nut 123, and a tapping screw is mounted in the nut 123, one end of the tapping screw passes through the nut 123 and the bolt hole and abuts against the first hook portion 111.

[0038] In use, the first hook portion 111 is hung on the cathode rod, and the tapping screw mounted on the second hook portion 122 drives the conductive copper bar 110 to tightly contact with the electroplating cathode rod, thereby improving the conductivity. The piston rod is inserted into the conductive sleeve 140 one by one, and then the electroplating workpiece is hung into the electroplating position for electroplating.

[0039] The lower conductive piston rod electroplating hanger can facilitate the feeding of workpieces, improve the number of electroplated piston rods in each electroplating position under the premise of ensuring the electroplating taper, and thus improve the electroplating efficiency of the piston rod workpiece.

[0040] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
