Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electroplating fixture technology, and specifically relates to an electroplating fixture for a hydraulic cylinder chrome-plating piston rod. Background Technology
[0002] Electroplating is a crucial step in the machining of hydraulic cylinder piston rods. Currently, most piston rod electroplating uses a single-layer upper conductive hanger, with a conductive head fixedly mounted on the hook. The conductive head has internal threads. When using the hanger, the external threads on the piston rod need to connect with the internal threads of the conductive head. Because piston rods are relatively heavy, approximately 15kg-20kg, loading and unloading them requires prolonged support, making it strenuous and requiring two people to operate. Furthermore, when unloading, the piston rod may suddenly disengage from the conductive head's threads; if the operator doesn't catch the product in time, it can easily fall, posing a risk of injury.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0034] like Figure 1-6 As shown, this utility model provides a chrome-plated piston rod electroplating fixture for hydraulic cylinders, including: a conductive copper busbar 110, a conductive main beam 120, a conductive crossbeam 130, a conductive seat 140, and a conductive head 150.
[0035] One end of the conductive main beam 120 is fixedly connected to the conductive copper busbar 110. The conductive copper busbar 110 is a long strip plate, and the conductive main beam 120 is also a long strip plate, with the length of the conductive main beam 120 being greater than the length of the conductive copper busbar 110. The conductive main beam 120 is stacked on the outside of the conductive copper busbar 110 along its length, and bolt holes 121 are provided at the upper end of the conductive main beam 120. Bolt holes 111 are provided on the conductive copper busbar 110. The bolt holes 111 and 121 are aligned, and the conductive main beam 120 and the conductive copper busbar 110 are fixed together by installing bolts in the bolt holes 111 and 121.
[0036] At least two conductive crossbeams 130 are spaced apart on the conductive main beam 120 along its length, and the conductive crossbeams 130 are positioned near the lower end of the conductive main beam 120. The conductive crossbeams 130 are perpendicular to the conductive main beam 120.
[0037] At least two sets of conductive seats are provided, each corresponding to one of the conductive beams 130; that is, one set of conductive seats is provided on each conductive beam 130. Each set of conductive seats includes at least two conductive seats 140, and the conductive seats 140 in the same set are spaced apart along the length of the conductive beam 130. The top of each conductive seat 140 has a groove 141, and the side of each conductive seat 140 has a mounting opening 142, which extends to the middle of the conductive seat 140 and communicates with the groove 141.
[0038] The conductive head 150 includes a connecting sleeve 151, a connecting rod 152, and a support rod 153. The connecting sleeve 151 has a cylindrical structure and an opening at one end (lower end), and its inner wall has threads. One end (lower end) of the connecting rod 152 is fixedly connected to the other end (upper end) of the connecting sleeve 151; the support rod 153 is fixedly connected to the other end (upper end) of the connecting rod 152. The connecting rod 152 can move from the mounting port 142 into the conductive seat 140, allowing the support rod 153 to engage in the groove 141. The upper end of the piston rod workpiece 210 is connected to the connecting sleeve 151 via an external thread. The outer wall of the connecting sleeve 151 has a surface that mates with a wrench to facilitate the connection and disassembly of the piston rod workpiece 210 and the connecting sleeve 151.
[0039] As a preferred embodiment, both the connecting rod 152 and the support rod 153 are cylindrical rods; the connecting rod 152 is coaxially arranged with the connecting sleeve 151; the support rod 153 is perpendicular to the connecting rod 152, and the connecting rod 152 is connected to the middle position of the support rod 152.
[0040] Preferably, the conductive base 140 is cylindrical. The bottom (lower end) of the conductive base 140 is fixed to the conductive beam 130. A groove 141 is formed radially along the conductive base 140, extending radially through the top (upper end) of the conductive base 140. A mounting port 142 is also formed radially along the conductive base 140, with one end located on the outer circumference of the conductive base 140 and the other end extending inward to the center of the conductive base 140, communicating with the groove 141 at the top of the conductive base 140; and the mounting port 142 extends axially through the conductive base 140. The radial extension direction of the mounting port 142 is perpendicular to the radial extension direction of the groove 141.
[0041] In this embodiment, the groove 141 is configured as a V-shaped groove. The structure of the V-shaped groove, which is larger at the top and smaller at the bottom, makes it easier for the support rod 153 to enter or exit the groove 141.
[0042] The mounting port 142 (opening direction) is positioned towards the end edge or side edge of the conductive beam 130, and the conductive beam 130 has a clearance opening 131 aligned with the mounting port 142. The length of the connecting rod 152 is greater than the total thickness of the conductive beam 130 and the conductive base 140 combined, to facilitate the movement of the conductive head 150. Positioning the mounting port 142 towards the edge of the conductive beam 130 allows for easy mounting of the conductive head 150 onto the conductive base 140.
[0043] In this embodiment, each group (conductive base) is provided with two conductive bases 140, and the two conductive bases 140 are respectively disposed at both ends of the conductive beam 130. The mounting openings 142 of the two conductive bases 140 are respectively positioned towards the outer edge of the end of the conductive beam 130 to which they are located; that is, the mounting opening 142 of the conductive base 140 located at the left end of the conductive beam 130 is positioned towards the left end of the conductive beam 130, and the mounting opening 142 of the conductive base 140 located at the right end of the conductive beam 130 is positioned towards the right end of the conductive beam 130.
[0044] In this embodiment, the upper end of the conductive copper busbar 110 is bent to form a first hook portion 112, and the upper end of the conductive main beam 120 is bent to form a second hook portion 122. The second hook portion 122 passes around the top of the first hook portion 112 and is arranged in a surrounding manner on the outside of the first hook portion 112; wherein, the inner surface of the second hook portion 122 abuts against the outer surface of the first hook portion 112. A nut 123 is welded to the outside of the second hook portion 122, and a bolt hole is coaxially opened at the corresponding nut 123. A set screw is installed in the nut 123, and one end of the set screw passes through the nut 123 and the bolt hole, abutting against the first hook portion 112.
[0045] In use, the first hook 112 is hung on the cathode bar, and the top ribbon installed on the second hook 122 is locked to drive the conductive copper busbar 110 into close contact with the electroplating cathode bar, thereby improving conductivity. When installing the piston rod 210 workpiece, the piston rod workpiece 210 is first connected to the connecting sleeve 151 of the conductive head 150. Then, the connecting rod 152 of the conductive head 150 is moved from the mounting port 142 into the conductive seat 142, so that the position of the support rod 153 of the conductive head 150 is aligned with the groove 141 on the top of the conductive seat 140 and matched and engaged in the groove 141, thus completing the electroplating loading process of the piston rod workpiece 140.
[0046] The electroplating fixture for chrome-plated piston rods of hydraulic cylinders provided by this utility model, through the setting of a conductive seat 140 and the improvement of the structure of the conductive head 150, makes it easier to load and unload piston rod workpieces, improves loading and unloading efficiency, and avoids the risk of injury during unloading. Moreover, due to the structure of setting at least two conductive crossbeams, the number of piston rod workpieces electroplated in the same time can be at least doubled, improving electroplating efficiency.
[0047] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
