Problems solved by technology

Therefore, a certain type of engine (WS8) requires high precision in the size of the combustion chamber. Due to the stress concentration after welding, the stress in this part is released during heat treatment, resulting in serious deformation of the parts and difficulty in subsequent processing.

Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the present invention includes a support shaft, a base, a positioning pin, a bushing and a cover plate located at the upper end of the support shaft.

[0020] A protruding installation hole is arranged at the center of the lower surface of the upper cover plate, and the bushing can be installed in the installation hole, and the outer diameter is equal to the diameter of the installation hole. In order to increase the stability, a protruding ring is arranged on the periphery of the bush, and the through hole is engaged with the protruding ring, so that the protruding ring can limit the upper cover plate. Preferably, the inner diameter of the bush is equal to the outer diameter of the support shaft, so that the upper end of the support shaft can be better fixed in the bush. The upper cov...

Abstract

The invention provides a tool applied to engine heat treatment. The tool comprises a supporting shaft, a base arranged at the lower end of the supporting shaft, a locating pin, a lining sleeve and a cover plate, wherein an axial through hole is arranged at the central position of the base, a convex installation hole is arranged in the center of the lower surface of the upper cover plate, the lining sleeve is arranged in the installation hole, the upper end of the supporting shaft can extend into the lining sleeve, the lower end of the supporting shaft can extend into the through hole, a pin hole is arranged on the base, and the base can be fixed to a work platform through the locating pin. The tool disclosed by the invention can reduce part deformation, can prevent parts from deforming inheat treatment and prevent subsequent processing from being performed, can improve part yield and can overcome delay and even scrap caused by part deformation.

Description

technical field [0001] The invention relates to the technical field of tooling, in particular to a tooling used for engine heat treatment. Background technique [0002] The engine combustion chamber is a device in which the fuel generates high-temperature gas, and the engine casing is required to have a certain compressive strength and rigidity. Therefore, a certain type of engine (WS8) requires high precision in the size of the combustion chamber. Due to the stress concentration after welding, the stress in this part is released during heat treatment, resulting in serious deformation of the parts and difficulty in subsequent processing. [0003] If a matching special tool can be designed, the engine combustion chamber can be fixed on the special tool, the influence of stress can be eliminated, and the qualified rate of the product can be increased. Contents of the invention [0004] In order to solve the above problems, the present invention provides a tool for heat trea...
