Description

Technical Field

[0001] The utility model relates to the field of heat treatment fixtures, in particular to a heat treatment fixture for shaft parts which is anti-slip. Background Art

[0002] Heat treatment refers to a metal hot processing technology that obtains the same structure and properties as the material by means of heating, heat preservation and cooling in the solid state. In the processing of bearing parts, due to process requirements, cylindrical workpieces are often subjected to normalizing, quenching, annealing, tempering and other heat treatment operations to enhance the hardness of the metal.

[0003] Shaft parts are important parts commonly used in mechanical equipment to transmit torque. After being processed and formed, shaft parts need to be heat treated to increase the physical properties of long shaft parts. Due to their long axial length, shaft parts are prone to deformation during heat treatment in a high temperature environment if they are not fixed properly, resulting in a large number of defective products. However, traditional shaft parts fixtures are not easy to install, and due to the small number of fixing points, they are prone to slippage. Based on this, the utility model proposes an anti-slip shaft parts heat treatment fixture, which can quickly clamp shaft parts and can adjust the position through a slider to meet the heat treatment positioning and fixation of shaft parts of different lengths; at the same time, because the fixture is equipped with two upper chucks and a lower chuck, its fixation is more stable.
