Floating joint and punch applying floating joint

Abstract

The invention discloses a floating joint and a punch applying the floating joint. The floating joint comprises a male joint, a female joint and a cover plate, wherein the upper end of the male joint is a connecting end; the lower end of the male joint is fixedly clamped in a cavity formed by connecting the cover plate and the female joint; the lower end of the female joint is provided with a connecting structure. The floating joint is reasonable in structure; punching and necking are performed on components, so that high accuracy and easiness in machining can be realized easily, radial errors, axial errors and angular errors within certain ranges can be corrected, the axial length can be adjusted, and high adaptability is achieved. The characteristic of the presence of a bearing, a spring or other elastic structures in the conventional floating joint is abandoned; a novel flexible connecting structure is adopted, so that assembly errors are eliminated, and higher pressure can be borne at the same time; the floating joint has the advantages of little wear, long service life, reliable structure, high tensile strength, high compression resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of machining components, and relates to a mechanical connection device. Background technique [0002] The function of the floating joint is to connect two shafts in different mechanisms, the driving shaft and the driven shaft, so that they rotate together to transmit torque. The second is to eliminate errors, especially in some high-speed and heavy-load environments, the output of the power mechanism is relatively large. If the direction of the force and the point of force are not on the same line when the power mechanism is extended, the shaft rod is easy to deform , One end of the floating joint is floating, which can be used to absorb or correct the lateral force, to achieve flexible connection, even if there are some dimensional deviations, it is not a big problem, to protect related components and make the equipment run smoothly, and to prolong the service life of the equipment.

Problems solved by technology

[0003] The traditional floating joint has bearings, springs or other elastic components inside, which cannot withstand high pressure, is easy to wear, has a short service life, and has a complex structure. It requires high machining accuracy and assembly accuracy and is difficult to guarantee, resulting in high costs.
