Spring-type quenching clamp assembly

Abstract

The invention relates to a clamp assembly which is used for quenching a workpiece and in particular relates to a spring-type quenching clamp assembly. The spring-type quenching clamp assembly comprises a rack, an outer sleeve, an inner sleeve, a limiting clamp and a clamping body, wherein the inner sleeve is arranged below the outer sleeve; a quenching oil hole is formed on the inner sleeve; the extending end of the inner sleeve is arranged on the inner part of the outer sleeve; an inclined surface structure which is fitted with the outer sleeve and the inner sleeve is arranged on a branch structure, respectively; an annular flange for supporting the limiting clamp is supported at the top end of the branch structure; a boss is arranged in the limiting clamp; the limiting clamp is supported by a bracket and arranged on the inner part of the inner sleeve; and the bracket is connected with a drive device. Compared with the prior art, the spring-type quenching clamp assembly has the advantages of reducing the deflection after quenching, reducing the subsequent processing amount and the processing amount of the early process, and reducing the cost; the spring-type quenching clamp assembly can be fitted to various associated equipment and can be used for realizing various working modes such as a continuous working mode, a single-step working mode, and the like; moreover, the optional range is large and the production efficiency is greatly improved; the limited-type quenching of the workpieces with different sizes can be realized by changing the clamping body; and the mould is simple and convenient to change.

Description

technical field [0001] The invention relates to a fixture assembly for quenching workpieces, in particular to a spring type quenching fixture assembly. Background technique [0002] At present, when quenching workpieces of rotating bodies such as bearing rings and friction rings, free quenching or other simple forms of limited quenching are used. There are following limitations and deficiencies: [0003] The product is deformed after quenching. Due to the combined effect of thermal stress and structural transformation stress, thin-walled parts deform greatly; free quenching or other simple forms of limited quenching are difficult to ensure that the predetermined deformation range is reached after quenching, which increases the difficulty of subsequent processing and production improvement. . [0004] The production efficiency is low. Due to the limitation of the equipment, it can only be operated automatically with a single station or a double station, or manual operation...

AI Technical Summary

Problems solved by technology

[0003]The product has large deformation after quenching

Due to the combined effect of thermal stress and structural transformation stress, thin-walled parts deform greatly; free quenching or other simple forms of limited quenching are difficult to ensure that the predetermined deformation range is reached after quenching, which increases the difficulty of subsequent processing and production improvement.

[0004]The production efficiency is low. Due to the limitation of the equipment, it can only be operated automatically with a single station or a double station, or manual operation. The number of stations is small and the production efficiency is low.

[0005]Due to large deformation, material utilization rate is low and often results in scrap
