Abstract

The invention relates to the technical field of quenching equipment, and provides an inner wall quenching device which comprises heating structures arranged on the inner wall of a cylinder barrel, and a driving unit is connected between the heating structures through a connecting rod mechanism so as to adjust the diameter of the heating structures; and the inner wall supporting structure is supported on the inner wall of the cylinder barrel, the inner wall supporting structure comprises first sliding blocks and an inner supporting structure, an air pressure cavity is formed between the first sliding blocks, and the first sliding blocks push the inner supporting structure to adjust the diameter of the inner wall supporting structure. According to the inner wall quenching device provided by the invention, the diameter of the heating structure is adjusted by utilizing the connecting rod mechanism, and the diameter of the inner wall supporting structure is adjusted by utilizing expansion and contraction of the air pressure cavity; and the heating structure and the inner wall supporting structure do not need to be replaced, so that the quenching requirements of cylinder barrels/steel pipes with different inner diameter specifications are met, the quenching working efficiency is improved, the applicability of the device is expanded, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to an inner wall quenching device. Background technique [0002] The hydraulic cylinder is an important part of the mechanical equipment to realize the operation action. In order to meet the working strength requirements of the construction machinery, it has high quality requirements. As the main part of the hydraulic cylinder, the inner wall surface of the cylinder bears the impact of high-pressure hydraulic oil and the continuous friction of the piston and seal during operation. Generally, quenching is used to increase the hardness of the inner wall of the cylinder and refine the metallographic structure of the inner wall to achieve the purpose of wear resistance. [0003] At present, the main structure of the inner wall quenching device of a cylindrical structure such as an oil cylinder includes: a heating coil, a double-layer copper rod for cooling water, a universa...
