Description

Technical Field

[0001] The utility model relates to the technical field of piston rod electroplating, in particular to a tool for simultaneously electroplating the inside and outside of a deep hole piston rod. Background Art

[0002] Copper-tin alloy plating has good corrosion resistance and is currently widely used in high-end hydraulic support jack piston rods. Its advantages are particularly prominent in mining environments such as high temperature, high humidity, high chloride ions, and high sulfate ions.

[0003] At present, the deep holes of the piston rods of high-end hydraulic support jacks are also required to be electroplated with copper-tin alloy. The general electroplating method is to electroplate the deep holes first, with the piston end facing upward and hung on the piston end, and then electroplate the outer circle, with the piston end facing downward and hung on the rod head end. The deep hole part and the outer circle surface need to be electroplated separately, resulting in the piston rod with deep holes needing to be electroplated twice, which makes the electroplating process long and reduces production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a tool for simultaneously electroplating the inside and outside of a deep-hole piston rod, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides a tool for simultaneous electroplating of the inside and outside of a deep-hole piston rod, comprising a tool frame, wherein two large hooks are fixedly connected to the upper side of the tool frame, and a small hook is fixedly connected to one side of the large hook. A plurality of piston rods with inner holes are arranged inside the tool frame, and an electroplating mechanism is arranged inside the piston rod with an inner hole, and the electroplating mechanism is used for simultaneous electroplating of the inside and outside of the piston rod with an inner hole, and the electroplating mechanism comprises a conductive copper busbar, which is fixedly connected to the upper end side of the tool frame, and a plurality of anode fixing modules are fixedly connected to the inner top wall of the tool frame, and a conductive wire is fixedly connected to the inside of the anode fixing module, and an auxiliary anode is fixedly connected to the inside of the anode fixing module, and insulation treatment is performed between the auxiliary anode and the anode fixing module, and the lower end of the auxiliary anode extends to the inside of the piston rod with an inner hole, and insulating rings are equidistantly sleeved on the auxiliary anode.

[0006] As a further improvement of the present technical solution, the inner bottom wall of the tooling frame is fixedly connected with multiple bases, and the bases are aligned with the center position of the anode fixing module. Fixed blocks are provided on both sides of the base, and the interior of the fixed block is threadedly connected to the lower end of the piston rod with an inner hole by bolts.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: by fixing the piston rod with an inner hole on the base, inserting the lower end of the auxiliary anode into the piston rod with an inner hole, and fixing the upper end of the auxiliary anode on the anode fixing module, the auxiliary anode is connected to the rectifier anode through a conductive wire and a conductive copper bus, thereby achieving simultaneous electroplating of the inner hole and outer circle of the piston rod with an inner hole, and completing the electroplating in one time, reducing the electroplating process and thus improving production efficiency.

[0018] Example 1

[0019] See also Figure 1-Figure 4 As shown, this embodiment provides a tool for simultaneous electroplating of the inside and outside of a deep-hole piston rod, including a tool frame 1, two large hooks 11 are fixedly connected to the upper side of the tool frame 1, and a small hook 12 is fixedly connected to one side of the large hook 11. A plurality of piston rods 3 with inner holes are arranged inside the tool frame 1, and an electroplating mechanism is arranged inside the piston rods 3 with inner holes. The electroplating mechanism is used for simultaneous electroplating of the inside and outside of the piston rods 3 with inner holes.

[0020] The electroplating mechanism includes a conductive copper busbar 33, which is fixedly connected to the upper side of the tooling frame 1, and the connection parts are insulated. A plurality of anode fixing modules 32 are fixedly connected to the inner top wall of the tooling frame 1, and the interior of the anode fixing module 32 is fixedly connected with a conductive wire 34. The interior of the anode fixing module 32 is fixedly connected with an auxiliary anode 31, and the auxiliary anode 31 and the anode fixing module 32 are insulated. The lower end of the auxiliary anode 31 extends to the interior of the piston rod 3 with an inner hole. The auxiliary anode 31 is a device for electroplating deep holes in the piston rod 3 with an inner hole. It is connected to the rectifier anode through the conductive wire 34 and the conductive copper busbar 33. Insulating rings 35 are equidistantly sleeved on the auxiliary anode 31 to prevent sparks during the electroplating process, which affects the electroplating effect of the piston rod 3 with an inner hole.

[0021] The inner bottom wall of the tooling frame 1 is fixedly connected with multiple bases 2, which have the same shape as the piston rod 3 with an inner hole, and the base 2 is aligned with the center position of the anode fixing module 32. The base 2 is a device for fixing the piston rod 3 with an inner hole. Fixed blocks 21 are provided on both sides of the base 2. The fixed block 21 is used to fix the piston rod 3 with an inner hole on the base 2. The interior of the fixed block 21 is threadedly connected to the lower end of the piston rod 3 with an inner hole with a bolt 22. By placing the piston rod 3 with an inner hole on the base 2 and rotating the bolt 22 in cooperation with the fixed block 21, the piston rod 3 with an inner hole is fixed to the base 2. The tooling frame 1, the outer side of the base 2, the anode fixing module 32 and the conductive copper bus 33 are all coated with hanger glue. The hanger glue mainly plays the role of insulation and corrosion protection. At the same time, the glue layer is thick and smooth with good toughness, which extends the service life of the device.

[0022] When the deep-hole piston rod internal and external simultaneous electroplating tool of this embodiment is used, the piston rod 3 with an inner hole is placed on the base 2, and the piston rod 3 with an inner hole is fixed to the base 2 by bolts 22 and fixing blocks 21. The lower end of the auxiliary anode 31 is inserted into the piston rod 3 with an inner hole, and the upper end of the auxiliary anode 31 is fixed on the anode fixing module 32. The auxiliary anode 31 is connected to the rectifier anode through a conductive wire 34 and a conductive copper bus 33, thereby realizing the simultaneous electroplating of the inner hole and outer circle of the piston rod 3 with an inner hole, reducing the electroplating process and thus improving production efficiency.
