Description

Technical Field

[0001] The utility model relates to the technical field of ion nitriding clamping, in particular to a stable clamping tool. Background Art

[0002] Nitriding treatment refers to a chemical heat treatment process that allows nitrogen atoms to penetrate into the surface of the workpiece at a certain temperature and in a certain medium. The products treated with nitriding have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. During the nitriding process, the product needs to be fixed.

[0003] Some equipment on the market generally uses a bidirectional motor, an adjusting screw and a threaded seat to adjust the distance between the first support plate and the load-bearing base plate, and then adjusts the distance between the second support plate and the first support plate by extending and retracting the telescopic support rod, making it convenient to place products of different sizes and specifications according to needs during use.

[0004] However, during the actual use of the above equipment, the product is clamped between the support plates, which prevents the contact surface of the product with the support plates from being well contacted with the nitrogen during the nitriding treatment, resulting in poor nitriding effect of the product; in view of this, we proposed a stable clamping tool.
