Description

Technical Field

[0001] This utility model relates to the field of metal processing, and in particular to an electrolytic polishing fixture. Background Technology

[0002] Before testing metal product samples, the surface to be tested needs to be flat and clean to facilitate subsequent inspections, such as scanning electron microscopy and microscopic observation. Electropolishing is typically used to treat the workpiece, thus facilitating subsequent testing. However, most existing electropolishing methods perform electropolishing on the entire workpiece and lack electropolishing fixtures specifically designed for this purpose. Therefore, there is a need for an electropolishing fixture that meets the requirements of small-batch, single-sided inspection, has a simple structure, a stable connection, reduces the influence of human factors, and provides better polishing results. Utility Model Content

[0003] The main purpose of this utility model is to provide an electropolishing fixture that meets the needs of small-batch single-sided inspection processing, has a simple structure, a stable connection, reduces the influence of human factors, and has a better polishing effect.

[0004] This utility model proposes an electrolytic polishing fixture, including an electrode connecting rod, a fixture body and a pressing screw;

[0005] The top of the clamp body is fixedly connected to the electrode connecting rod, and the bottom of the clamp body is provided with a long strip-shaped connecting protrusion and a supporting protrusion, which are arranged opposite to each other.

[0006] The connecting protrusion is provided with at least one connecting threaded hole, the workpiece is disposed between the connecting protrusion and the supporting protrusion, the pressing screw is threadedly connected to the connecting protrusion through the connecting threaded hole, and passes through the connecting threaded hole to press the workpiece onto the supporting protrusion.

[0007] Preferably, the support protrusion is disposed in the middle of the bottom of the clamp body, and there are two connecting protrusions disposed opposite each other on both sides of the support protrusion.

[0008] Preferably, the connecting threaded hole is partially disposed on the connecting protrusion and partially disposed on the clamp body, and the connecting threaded hole extends toward the inner side of the clamp body to form a threaded groove disposed between the connecting protrusion and the supporting protrusion;

[0009] By setting threaded grooves, the pressing screw can press down on a relatively thin workpiece, and the electropolishing fixture should not come into contact with the liquid surface as much as possible.

[0010] Preferably, the bottom of the electrode connecting rod is provided with a threaded connector, and the top of the clamp body is provided with a fixed threaded hole. The clamp body is threadedly connected to the bottom of the electrode connecting rod by the engagement of the threaded connector and the fixed threaded hole.

[0011] Preferably, the top of the electrode connecting rod is provided with an electrode connecting rod connecting hole, and the electrode connecting rod can be connected to the positive terminal of the power supply through the electrode connecting rod connecting hole.

[0012] The beneficial effects of the electrolytic polishing fixture of this utility model are as follows:

[0013] 1. It can clamp multiple workpieces at the same time without interfering with each other, which can effectively improve the electropolishing efficiency of the workpieces.

[0014] 2. By setting threaded grooves, it is possible to prevent the pressing screw from extending beyond the bottom surface of the fixture body after being screwed on. The area to be polished is only the bottom plane area of ​​the workpiece, which can make the electrolytic polishing fixture as far from contacting the liquid surface as possible.

[0015] 3. Electrolytic polishing fixtures can move vertically by suspension. Compared with manual hand operation, the workpiece is more stable when in contact with the electrolyte surface, reducing the influence of human factors on the polishing effect. This results in more stable current and voltage and better polishing effect. Attached Figure Description

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] Reference Figures 1 to 4 An embodiment of the electropolishing fixture of this utility model is presented:

[0024] An electropolishing fixture includes an electrode connecting rod 1, a fixture body 2, and a pressing screw 3.

[0025] The electrode connecting rod 1 has an electrode connecting rod connecting hole 11 at its top, through which it can be connected to the positive terminal of the power supply. The electrode connecting rod 1 has a threaded connector 12 at its bottom.

[0026] The top of the clamp body 2 is provided with a fixing threaded hole 25. The clamp body 2 is threadedly connected to the bottom of the electrode connecting rod 1 by the engagement of the threaded connector 12 with the fixing threaded hole 25. The bottom of the clamp body 2 is provided with an elongated connecting protrusion 22 and a supporting protrusion 21. The supporting protrusion 22 is located in the middle of the bottom of the clamp body 2. There are two connecting protrusions 21, which are arranged opposite each other on both sides of the supporting protrusion 22 and are located on the edge of the clamp body 2.

[0027] The connecting protrusion 21 has three threaded holes 23, some of which are located on the connecting protrusion 22 and some on the fixture body 2. The threaded holes 23 extend inward to form a threaded groove 24 between the connecting protrusion 22 and the supporting protrusion 21. The workpiece 4 is placed between the connecting protrusion 22 and the supporting protrusion 21. The pressing screw 3 is threadedly connected to the connecting protrusion 22 through the threaded holes 23 and passes through the threaded holes 23 to press the workpiece 4 onto the supporting protrusion 21. By setting the threaded groove 24, the pressing screw 3 is prevented from extending beyond the bottom surface of the fixture body 2 after being screwed on. The area to be polished is only the bottom plane area of ​​the workpiece 4, which allows the electrolytic polishing fixture to avoid contact with the liquid surface as much as possible.
