[0037] 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.

[0038] like Figure 1-8 As shown, this utility model provides a quick-clamp conductive tooling for hard chrome plating of shock absorber piston rods, including: a clamping rod 100, a shielding cover 200, and a connecting bolt 300.

[0039] The clamping rod 100 includes a first clamping arm 110 and a second clamping arm 120, which are symmetrically arranged. One end of the first clamping arm 110 and the second clamping arm 120 are fixedly connected, while the other end is a free end.

[0040] In this embodiment, the clamping rod 100 is cylindrical in shape, and an elongated slot is cut along the axial symmetry plane of the clamping rod 100 to divide one end of the clamping rod 100 into a first clamping arm 110 and a second clamping arm 120. The thickness of the elongated slot, i.e., the gap between the first clamping arm 110 and the second clamping arm 120, is 4 mm; the length of the unslotted portion of the clamping rod 100 is at least 10 mm.

[0041] A first connecting hole 111 is formed on the first clamping arm 110 and is located near the free end of the first clamping arm 110. The first connecting hole 111 is formed radially along the clamping rod 100 and along the thickness direction of the elongated groove. A second connecting hole 121 is formed on the second clamping arm 120 and is coaxially arranged with the first connecting hole 111; wherein, the second connecting hole 121 is a threaded hole.

[0042] The shield 200 is coaxially sleeved on the clamping rod 100; the shield 200 has a first through hole 210 and a second through hole 220, the first through hole 210 and the second through hole 220 are coaxial, and the positions of the first through hole 210 and the second through hole 220 correspond to the first connecting hole 111 and the second connecting hole 121, respectively.

[0043] The connecting bolt 300 thread passes through the first through hole 210 and the first connecting hole 111 in sequence, and is threaded onto the second connecting hole 121. The free end of the thread passes through the second through hole 220 and extends to the outside of the second through hole 220.

[0044] As a preferred embodiment, the head of the connecting bolt 300 is equipped with a handle to facilitate tightening the connecting bolt 300. The handle may be made of thermosetting plastic or thermoplastic plastic.

[0045] A first groove 112 is formed along the central axis on the side of the first clamping arm 110 facing the second clamping arm 120. One end of the first groove 112 is located at the free end of the first clamping arm 110, and the other end extends to the first connecting hole 111. The cross-section of the first groove 112 is arc-shaped and matches the size of the threaded end of the piston rod workpiece to be clamped. A second groove 122 is formed on the second clamping arm 120, and the second groove 122 and the first groove 112 are symmetrically arranged about the central axis of the clamping rod 100.

[0046] The quick-clamp conductive tooling for hard chrome plating of the shock absorber piston rod further includes a connecting rod 400, which is a threaded rod coaxially fixedly connected to the clamping rod 100 and located at the connection end of the first clamping arm 110 and the first clamping arm 120 (i.e., the unslotted end of the clamping rod 100). The diameter of the connecting rod 400 is smaller than the diameter of the clamping rod 100. The connecting rod 400 is threadedly connected to the conductive seat of the electroplating equipment.

[0047] Preferably, the shielding cover 200 has at least one row of circular holes 230, with the holes 230 in the same row evenly spaced along the circumference of the shielding cover 200. The circular holes 230 are located close to the lower end of the shielding cover 200. In this embodiment, the diameter of the circular holes 230 is set to 12mm. By providing the circular holes 230, electric field lines can be shielded, resulting in a more uniform plating thickness on the electroplated product. Figure 8 As shown, in one embodiment, two rows of circular holes are provided, which are arranged along the circumference of the shield and are located near the lower end of the shield.

[0048] A baffle 240 is provided inside the shielding cover 200. The baffle 240 is annular and coaxially arranged with the shielding cover 200. The outer edge of the baffle 240 is fixedly connected to the inner wall of the shielding cover 200. The diameter of the central through hole 241 of the baffle 240 matches the diameter of the threaded end of the piston rod workpiece to be clamped. The baffle 240 is located above and close to the circular hole 230. The distance between the baffle 240 and the central axis of the first through hole 210 is greater than the distance between the free end of the first clamping arm 110 and the central axis of the first connecting hole 111. In this embodiment, the thickness of the baffle 240 is set to 5 mm.

[0049] In use, the baffle 240 is positioned below the free ends of the first clamping arm 110 and the second clamping arm 120. The threaded end of the piston rod workpiece to be clamped passes through the central through hole 221 of the baffle 240 and is inserted between the first groove 112 and the second groove 122. By tightening the connecting bolt 300, the piston rod workpiece is fixedly clamped between the first clamping arm 110 and the second clamping arm 120, thus completing the loading process.

[0050] The quick-clamp conductive tooling for hard chrome plating of shock absorber piston rods provided by this utility model can realize the quick clamping of shock absorber piston rods, which not only improves loading efficiency and reduces manual labor intensity, but also solves the quality problem of inconsistent conductivity, while avoiding the problem of electric shock.
