Description

Technical Field

[0001] The utility model relates to the technical field of piston rod processing, in particular to a piston rod surface electroplating device. Background Art

[0002] Surface electroplating of piston rods is an essential process in the production and processing of piston rods. Usually, the processed piston rods are placed in an electroplating pool for surface electroplating. After the electroplating is completed, the processed piston rods are fished out, wiped clean of water, and transferred to the subsequent process. At present, the process of wiping water after the piston rods are fished out is mainly completed by manpower, especially for large piston rods with a length of more than 1 meter or a weight of tons. It is very inefficient to wipe water by manpower after electroplating. Therefore, the current treatment method for large piston rods in the field is to fish out and control water or dry them. Although it saves labor, it undoubtedly increases waiting time and slows down the subsequent processing progress of the piston rods. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-Figure 3 The piston rod surface electroplating device shown includes an electroplating pool, and a salvage device is arranged above the electroplating pool; the salvage device includes a main board, and the upper end of the main board is connected to a moving device, such as a crane or gantry crane equipped in a workshop, which can lift the salvage device as a whole to the top of the electroplating pool and drive the salvage device to move horizontally. A wiping roller is fixed to the lower end of the main board, and the wiping roller is located on both sides of the main board. A salvage hook is arranged between the two wiping rollers. A through hole is opened in the middle of the main board, and the upper end of the salvage hook passes through the through hole and is fixedly connected to the sub-board, and a hydraulic cylinder is arranged between the sub-board and the main board.

[0019] The cylinder body of the hydraulic cylinder is installed on the main plate, and the telescopic end is installed on the auxiliary plate, so that the hydraulic cylinder can drive the auxiliary plate to move up and down relative to the main plate, thereby driving the salvage hook fixed to the auxiliary plate to move up and down.

[0020] The electroplating tank is made of cement and is long. A plurality of bolsters extending in the width direction are arranged in the electroplating tank, and a lower hook space is provided between two adjacent bolsters. The processed piston rod is placed in the electroplating tank in a corresponding length.

[0021] The number of the fishing hooks is at least two and is less than or equal to the number of the lower hook spaces; in this embodiment, the number of the fishing hooks is three, which are respectively located at the two ends and the middle of the main board. The fishing hook is located just above the lower hook space, so as to facilitate hooking the processing piston rod from the lower hook space.

[0022] The main board is long and arranged in the length direction of the electroplating pool. A plurality of salvage hooks are distributed in a straight line along the length direction of the main board, so that the salvage hooks can hook different parts of the processed piston rod.

[0023] The extension direction of the wiping roller is the same as the length direction of the main board. The wiping roller includes an axis roller and a water-absorbing cotton layer wrapped on the surface of the axis roller and having a thickness, preferably a sponge, and the thickness is preferably 3-5 cm; the distance between the two wiping rollers is smaller than the diameter of the processing piston rod. In this way, when the processing piston rod rises and passes through the two wiping rollers, the water-absorbing cotton layer of the wiping roller can be in pressure contact with the surface of the processing piston rod, thereby increasing the contact area between the wiping roller and the processing piston rod to absorb the moisture on the surface of the processing piston rod.

[0024] Connecting rods are fixed at both ends of the shaft roller, and the connecting rods are fixed on the main board. The length of the connecting rods is greater than the diameter of the processing piston rod, so that the processing piston rod can continue to rise after passing through the wiping roller. The water-absorbing cotton layer on the wiping roller is elastic and can recover its deformation after being squeezed. Therefore, when the processing piston rod passes through the wiping roller, the processing piston rod squeezes the water-absorbing cotton layer due to the small distance between the two wiping rollers. When the processing piston rod is located at a tangent position to the wiping roller, the water-absorbing cotton layer that is not squeezed recovers its original radius and can contact the position near the lower surface of the processing piston rod, so that water absorption is more comprehensive.

[0025] There are lifting rings installed at the four corners of the mainboard, and the lifting rings can be detachably connected to the moving device. The cranes and gantry cranes in the factory are usually connected to the heavy objects through hooks, so the hooks can be hooked on the four lifting rings. When not in use, the hooks can be taken off the lifting rings.

[0026] When in use, the fishing hook descends to the bottom of the electroplating tank and hooks the processed piston rod after electroplating. Then the hydraulic cylinder drives the fishing hook to rise. The processed piston rod first rises and leaves the electroplating tank liquid surface, and continues to rise and passes through the wiping roller to be absorbed. Then, the fishing device is driven by the moving device to move horizontally to the outside of the electroplating tank. The hydraulic cylinder drives the fishing hook to descend below the wiping roller, and the processed piston rod can be removed from the fishing hook.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
