[0002] The silvering method refers to sintering and infiltrating a layer of silver on the surface of a ceramic workpiece as the electrode of components such as capacitors and filters or the conductive network of an integrated circuit substrate. This technology is mainly used to improve the conductivity and antioxidant capacity of the ceramic workpiece. Columnar ceramic workpieces are used to manufacture capacitors, insulators, or part of certain mechanical components. When silvering a columnar ceramic workpiece,

[0003] The columnar ceramic workpiece needs to have conductivity on both end surfaces. After most clamping devices clamp the ceramic workpiece, only one end of the ceramic workpiece can be coated with a layer of silver film. When it is necessary to coat a layer of silver film on the other end, the ceramic workpiece needs to be removed from the clamping device and replaced with the other end, which is rather troublesome and reduces the work efficiency. Based on this, this solution provides a clamping device for double-sided silvering to solve the above-mentioned problems. Content of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] Refer to Figures 1-4 As shown, a clamping device for double-sided silvering includes a base 1. Both the left and right sides of the upper end of the base 1 are fixedly connected with mounting plates 2. The right end of the left mounting plate 2 is fixedly installed with a first bearing seat 3. A first rotating rod 4 is rotatably installed inside the first bearing seat 3. A second rotating rod 5 is rotatably installed inside the right mounting plate 2. There is a clamping assembly 6 between the second rotating rod 5 and the first rotating rod 4. The distance between the clamping assembly 6 and the support assembly 7 is long enough, and the clamping assembly 6 will not touch the support assembly 7 when rotating. The clamping assembly 6 includes a fixed frame 601. The left and right ends of the fixed frame 601 are respectively fixedly connected with the right end of the first rotating rod 4 and the left end of the second rotating rod 5. Threaded sleeves 602 are fixedly installed inside the front and rear ends of the fixed frame 601. Threaded rods 603 are threadedly connected inside both threaded sleeves 602. The inner sides of both threaded rods 603 are rotatably connected with second bearing seats 605. Clamping plates 606 are fixedly installed inside both second bearing seats 605. The left and right ends of both clamping plates 606 are respectively slidably connected with the inside of the fixed frame 601. The outer ends of both threaded rods 603 are fixedly connected with rotating blocks 604. A plurality of arc-shaped grooves 607 are opened on the inner sides of both clamping plates 606. First rubber pads 608 are provided on the inner walls of the plurality of arc-shaped grooves 607. The first rubber pads 608 can not only protect the outer surface of the columnar ceramic workpiece, but also provide a certain amount of friction, so that the two clamping plates 606 clamp the columnar ceramic workpiece more firmly.

[0025] Refer to Figures 3-4As shown in the figure, a rotating wheel 9 is fixedly installed at the right end of the second rotating rod 5. A limiting rod 10 is slidably installed inside the rotating wheel 9. At the right end of the right installation plate 2, two limiting holes 8 adapted to the limiting rod 10 are opened. The two limiting holes 8 are located on the upper and lower sides of the second rotating rod 5, and the two limiting holes 8 are axisymmetric about the center of the second rotating rod 5. By inserting the limiting rod 10 into the limiting hole 8, the rotating wheel 9 can be fixed, and then the clamping assembly 6 can be fixed, so that a silver film can be evenly coated on the surface of the columnar ceramic workpiece. A support assembly 7 is provided at the upper end of the base 1. The support assembly 7 includes a connecting plate 701. The lower end of the connecting plate 701 is fixedly connected to the upper end of the base 1. In the middle of the upper end of the connecting plate 701, an electric telescopic rod 702 is fixedly installed. The output end of the electric telescopic rod 702 is fixedly connected to a support plate 703. A second rubber pad 704 is provided at the upper end of the support plate 703. The second rubber pad 704 can prevent the columnar ceramic workpiece from directly contacting the support plate 703 and causing damage.

[0026] The working principle and usage process of the present utility model: When in use, place the columnar ceramic workpiece on the upper surface of the second rubber pad 704 at the upper end of the support plate 703, and the columnar ceramic workpiece is located between the arc-shaped grooves 607 opened on the inner sides of the two clamping plates 606. Rotate the rotating blocks 604 on both sides to drive the threaded rod 603 to rotate inside the threaded sleeve 602, so that the two clamping plates 606 move towards each other to clamp and fix the columnar ceramic workpiece. After the fixing is completed, the electric telescopic rod 702 contracts, and a silver film is coated on one side of the columnar ceramic workpiece. After one side is coated, take out the limiting rod 10 in the rotating wheel 9 from the upper limiting hole 8, then rotate the rotating wheel 9. After the rotating wheel 9 rotates 180 degrees, insert the limiting rod 10 into the lower limiting hole 8 to fix the rotating wheel 9. When the rotating wheel 9 rotates 180 degrees, the rotating wheel 9 drives the second rotating rod 5 to rotate. The second rotating rod 5 cooperates with the first bearing and the first rotating rod 4 to rotate the fixing frame 601 by 180 degrees, and then coat a silver film on the other side, completing the operation of silver plating on both sides of the columnar ceramic part, which is convenient and fast and improves work efficiency.
