Description

Technical Field

[0001] The utility model relates to the technical field of electroplating of metal products, and specifically relates to an electroplating device for metal products. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of using electrolysis to attach a metal film to the surface of metal or other material parts, so as to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhance beauty, etc.

[0003] When electroplating metal products, they need to be immersed in the electrolyte and connected to the negative electrode. After electroplating, they are taken out of the electrolyte. However, when the existing electroplating equipment electroplates metal products, since the metal products and the electroplating solution are generally in a static state and not easy to move, the concentration of the electroplating solution is not uniform enough, resulting in uneven electroplating on the surface of the metal products.

[0004] The utility model aims to solve the technical problems existing in the prior art. For this purpose, an electroplating device for metal products is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electroplating device for metal products to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An electroplating device for metal products includes an electrolytic cell and a support frame. The electrolytic cell is fixedly connected to the support frame. A lifting device is fixedly connected to one side of the support frame. A driving mechanism is rotatably connected to the lifting device. A transmission mechanism is slidably connected to the lifting device. The driving mechanism cooperates with the transmission mechanism. The other end of the transmission mechanism is fixedly connected to a fixing device.

[0008] As a further scheme of the utility model: The lifting device includes a cylinder. The cylinder is fixedly connected to the support frame. A telescopic rod is fixedly connected to the contact surface between the cylinder and the support frame. The other end of the telescopic rod is fixedly connected to a lifting block. A card slot is opened inside the lifting block. The card slot is in sliding contact with the transmission mechanism.

[0009] As a further scheme of the utility model: The transmission mechanism includes a transmission rod. The transmission rod vertically penetrates the card slot. A limiting rod is fixedly connected to the cylindrical surface of the transmission rod. The limiting rod is located in the card slot and is in sliding contact with the lifting block. The other end of the transmission rod is fixedly connected to a limiting block. The transmission rod cooperates with the driving mechanism. The other end of the transmission rod is fixedly connected to a fixing device.

[0010] As a further solution of the utility model: The driving mechanism includes a turntable, which is sleeved on the cylindrical surface of the telescopic rod and is in sliding contact with the telescopic rod. One side of the turntable is fixedly connected with a push rod. An inclined groove is opened inside the turntable, and the inclined groove is inclined. One end of the transmission rod extends into the inclined groove and is in sliding contact with the turntable. The limiting block vertically limits the support frame.

[0011] As a further solution of the utility model: The fixing device includes a connecting block. A spring is fixedly connected to the inner surface of the connecting block. The other end of the spring is fixedly connected with a pressing block. The pressing block is in sliding contact with the connecting block. A clamping jaw is rotatably connected to the cylindrical surface of the pressing block. One side of the clamping jaw is in sliding contact with the connecting block. A limiting slider is fixedly connected to the cylindrical surface of the pressing block. A limiting sliding groove is opened on the inner surface of the connecting block. The limiting slider is located in the limiting sliding groove and is in sliding contact with the connecting block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. The device drives the turntable to rotate by pushing the push rod. The turntable drives the inclined groove to rotate. Since the inclined groove is inclined, one end of the transmission rod is located in the inclined groove and is in sliding contact with the turntable. At the same time, the clamping groove limits the transmission rod through the limiting rod so that it can only move horizontally. That is, when driving the inclined groove to rotate forward, the vertical intersection point of the inclined groove and the clamping groove gradually deviates towards the center of rotation of the turntable. That is, the turntable squeezes the transmission rod to make the transmission rod move. The transmission rod drives the connecting block to move. The connecting block drives the pressing block to move through the spring. That is, the pressing block squeezes the workpiece. According to the reciprocity of forces, it can be understood that the pressing block is squeezed by the workpiece, then the pressing block moves to squeeze the spring, and at the same time the pressing block drives the clamping jaw to move. Since one side of the clamping jaw is in sliding contact with the connecting block, when the clamping jaw moves, one side of the clamping jaw is squeezed by the connecting block and expands. According to the lever principle, the other end of the clamping jaw contracts to clamp and fix the workpiece, which can facilitate the fixing of the workpiece and the removal of the workpiece after electroplating is completed;

[0013] 2. The device controls the telescopic rod to extend, that is, the telescopic rod drives the support frame to descend. The support frame drives the connecting block to descend through the limiting rod and the transmission rod. The connecting block then drives the workpiece to descend into the electrolytic cell through the pressing block and the clamping jaw for electroplating, which can facilitate the adjustment of the position of the workpiece in the electrolytic cell and avoid the uneven electroplating on the surface of the metal product caused by the non-uniform concentration of the electroplating solution due to the long-term stillness of the workpiece.
