Adjustable prestress heat treatment fixture

Abstract

The invention provides an adjustable prestress heat treatment fixture which comprises V-shaped iron, a guide rod, a screw rod and a base, wherein the lower part of the screw rod and the lower part of the guide rod are respectively fixed connected to the base, and the upper part of the screw rod and the upper part of the guide rod are respectively in clearance fit with the V-shaped iron; a steel ball is arranged on the upper part of the screw rod and the upper part of the steel ball is contacted with the V-shaped iron, wherein the guide rod can be used for fixing the position of the V-shaped iron in the horizontal direction, and the screw rod can be used for adjusting the height of the V-shaped iron in the vertical direction. The heat treatment fixture disclosed by the invention has the following beneficial effects that the heat treatment fixture has the advantages of being simple in structure, convenient to use, wide in application, long in service life and the like.

Description

technical field [0001] The invention belongs to the technical field of heat treatment tooling, in particular to an adjustable prestressed heat treatment tool capable of controlling and adjusting the heat treatment deformation of stepped shafts. Background technique [0002] In industrial mechanical structures, stepped shaft workpieces are often required. Due to the small machining allowance after the quenching process, it is necessary to control the deformation of the workpiece during the heat treatment process. The traditional heat treatment tooling is: directly use V-shaped iron to suspend the workpiece or directly place the workpiece horizontally on the flat tooling. Although these two traditional methods can ensure the level of the workpiece, due to the stress changes during the heat treatment process and the workpiece Due to its own weight, there are often technical problems such as out-of-tolerance workpiece deformation during heat treatment, and difficult alignment du...

The traditional heat treatment tooling is: directly use V-shaped iron to suspend the workpiece or directly place the workpiece horizontally on the flat tooling. Although these two traditional methods can ensure the level of the workpiece, due to the stress changes during the heat treatment process and the workpiece Due to its own weight, there are often technical problems such as out-of-tolerance workpiece deformation during heat treatment, and difficult alignment due to the special shape of the workpiece.
