This invention relates to the field of electroplating equipment technology, and in particular to an electroplating device for precision electroplating of aerospace parts. The device includes a base plate and a sealing top plate. An electroplating tank is fixedly connected to the front side of the top of the base plate. Two symmetrical crossbars are fixedly connected between the left and right side walls inside the electroplating tank. Multiple linearly arrayed metal baskets are hung at the bottom of each crossbar. A locking mechanism is used to lock the sealing base plate and the sealing top plate together, thereby sealing the inside of the conical cylinder and preventing the inner surface of the conical cylinder from being plated with precious metals, reducing waste of precious metals and lowering electroplating costs. An electroplating adjustment mechanism ensures that the inner wall of the conical cylinder can be uniformly and periodically electrically connected to the electrodes, resulting in relatively similar attraction of metal ions at different locations, effectively reducing the thickness error of the metal coating on the outer surface of the conical cylinder.

The utility model discloses a kind of outer wall screw hole waterproof brushing devices, it is related to building construction field, technical scheme is, including paint box and brush, the upper portion of paint box is provided with opening, the side of paint box is fixedly provided with positioning plate, positioning plate is rectangular, and through hole is opened on the board body of positioning plate;Brush includes handle, and handle is fixedly provided with brush holder, and brush holder is fixedly provided with brush hair;Paint box is fixedly provided with handle on the side opposite to positioning plate, and clamping groove is opened on handle, and clamping groove is connected with handle.The beneficial effects of the utility model are that: the standardization of brushing size can be realized, the image of outer wall waterproof construction is improved, the thickness and uniformity of brushing are facilitated to control, and thickness error is reduced;Waterproof coating dripping waste when brushing waterproof coating can be reduced, recycling of dripping waterproof coating is realized, thereby material cost is reduced;It can be carried on site, and it is simple and practical to operate, and construction efficiency is improved.
