Description

Technical Field

[0001] The invention relates to the field of electroplating equipment, and in particular to an electroplating hanger device. Background Art

[0002] The electroplating hanger is one of the important factors to ensure that the plated parts meet the process requirements. Usually the hanger is composed of hooks, vertical poles, support rods, hooks and other parts. After the parts are hung, they become one with the hanger, and the relative position and angle remain unchanged. They are connected to the power supply electrode through the hanger. The parts to be plated on the gear parts are the gear teeth and splines, and local protection hoisting tank electroplating is required. Figure 1 As shown, during the electroplating process, the far anode area of ​​the part 20 caused by the hanging always exists, so it is necessary to rotate the hanger 90 degrees to make the far anode area of ​​the part face the anode plate 101, and adjust the deposition speed of the far anode area and the near anode area of ​​the part, so that the coating thickness is uniform on the circumference of the gear teeth. Conventional hangers need to rotate with the parts as a whole, which makes the operation difficult, and the power needs to be cut off during the rotation process, and the electroplating cannot be carried out continuously, which easily leads to the stratification of the coating, which is not conducive to ensuring the quality of the coating. For this reason, a dual DC power supply conductive mechanism is proposed on the market to realize the requirement of powering the workpiece during the rotating hanging plating process, but the mechanism is complex, the operation is complex, and the maintenance cost is high.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figures 2 to 6An embodiment of the electroplating hanger device of the present invention is shown. The electroplating hanger device of this embodiment includes a hook 1 and a hanging member 2 for hanging parts 20, and also includes a rotating mechanism 3, and the rotating mechanism 3 is connected between the hook 1 and the hanging member 2. Preferably, the hanging member 2 is a rod, which has a simple structure and is convenient for connecting with the connecting sleeve 34. At the same time, the flexible conductive member 4 is fixed thereon with a locking nut 52. Of course, in other embodiments, the hanging member 2 can also be in other forms.

[0032] The electroplating hanger device of this embodiment further provides a rotating mechanism 3 between the hook 1 and the hanging component 2, so that the hanging component 2 can rotate relative to the hook 1 under the action of external force. When the part 20 needs to be rotated 90 degrees during the electroplating process, the hook 1 can remain stationary, and only the part 20 and the hanging component 2 need to be rotated 90 degrees. The structure is simple, the cost is low, and the operation is convenient.

[0033] See Figure 2 and Figure 3 Further, in this embodiment, the rotating mechanism 3 includes a connecting shaft 31 fixedly connected to the hook 1, and a first end face gear 32 and a second end face gear 33 arranged on the connecting shaft 31, the first end face gear 32 meshes with the second end face gear 33, the hanging part 2 is fixedly connected to the first end face gear 32, and the second end face gear 33 is fixedly connected to the connecting shaft 31. As a further preferred technical solution, the first end face gear 32 is arranged above the second end face gear 33, and the lower end face of the first end face gear 32 and the upper end face of the second end face gear 33 are provided with gear teeth 331. When the part 20 needs to be rotated 90 degrees during the electroplating process, the part 20, the hanging part 2 and the first end face gear 32 can rotate around the connecting shaft 31, and the second end face gear 33, the connecting shaft 31 and the hook 1 remain stationary, which is convenient for operation. Under the gravity of the part 20, the first end face gear 32 and the second end face gear 33 mesh with each other, which can prevent the first end face gear 32 from accidentally rotating, thereby maintaining the relative position of the part 20, and having good reliability.

[0034] See Figures 4 to 6 Furthermore, in this embodiment, the gear teeth 331 of the first end face gear 32 and the second end face gear 33 are provided with mutually matching inclined surfaces 332 to realize the unidirectional rotation of the first end face gear 32. After a certain external force is applied, the first end face gear 32 can realize positive rotation along the direction of the inclined surface 332, but cannot rotate in the reverse direction, thereby maintaining the relative position of the part 20, further improving the reliability of the device.

[0035] Furthermore, in this embodiment, the first end face gear 32 can be axially moved along the connecting shaft 31. When no electroplating operation is performed, the first end face gear 32 can be axially moved along the connecting shaft 31 for a certain distance so that the first end face gear 32 is disengaged from the second end face gear 33. At this time, the first end face gear 32 can rotate forward and reverse, which is convenient for disassembly and maintenance. When electroplating operation is required, the first end face gear 32 is moved in the reverse direction so that the first end face gear 32 and the second end face gear 33 are meshed again.

[0036] As a preferred embodiment, a limiting flange 311 is provided at the end of the connecting shaft 31, and the limiting flange 311 is welded to the second end face gear 33, and the welding connection is high in strength and good in reliability.

[0037] As a preferred embodiment, a connecting sleeve 34 is welded on the outer periphery of the first end face gear 32, which has good connection reliability and is convenient for synchronous rotation. The connecting sleeve 34 is detachably connected to the mounting member 2. The connecting sleeve 34 can provide a certain protection for the first end face gear 32 and the second end face gear 33, and also connects the mounting member 2 and the first end face gear 32 as a whole. The connecting sleeve 34 is detachably connected to the mounting member 2, which is convenient for disassembly and maintenance.

[0038] As a preferred embodiment, the connecting sleeve 34 is threadedly connected to the hanging member 2. Specifically, the lower part of the connecting sleeve 34 is provided with an internal thread hole, and the hanging member 2 is provided with an external thread, so that the connection is reliable and easy to disassemble and assemble. Of course, in other embodiments, the internal and external threads can also be exchanged.

[0039] See Figure 2 In this embodiment, a flexible conductive member 4 is connected between the hook 1 and the hanging member 2. The first end face gear 32 can freely rotate 90 degrees in a fixed rotation direction. During the rotation, the change in the contact gap between the gear teeth 331 of the first end face gear 32 and the second end face gear 33 may not be able to maintain a tight connection to transmit current. In this case, the current required for the electroplating of the part 20 can be transmitted through the flexible conductive member 4 connecting the hook 1 and the hanging member 2, without causing power outages and plating stratification. It is suitable for plating types and workpieces with high requirements for plating quality and thickness uniformity, such as local silver plating, cadmium plating, copper plating and other electroplating processes of aviation gears, and the flexible conductive member 4 will not hinder the rotation of the part 20. The flexible conductive member 4 can be, for example, a flexible cable.

[0040] Furthermore, in the present embodiment, the rotating mechanism 3 is connected to the hook 1 by a threaded fastener 51 (such as a bolt or a screw), one end of the flexible conductive member 4 is sleeved on the threaded fastener 51 (for example, a conductive sheet with holes or a conductive connector is welded at both ends of a flexible cable, etc.) and is provided with a locking nut 52. The connection is reliable and the disassembly and maintenance are convenient. The other end of the flexible conductive member 4 is sleeved on the hanging member 2 and locking nuts 52 are clamped on both sides. The structural reliability is high and the disassembly and maintenance are convenient.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
