Eccentric bushing with eccentricity adjusting structure

Abstract

The invention discloses an eccentric bushing with an eccentricity adjusting structure. The eccentric bushing with the eccentricity adjusting structure comprises an eccentric bushing main body and an assembling ring, internal threads are arranged inside the eccentric bushing main body, the assembling ring is installed at the front end of the eccentric bushing main body, an unthreaded hole is formedinside the assembling ring, a left arc block is installed on the left side of the assembling ring, a right arc block is installed on the right side of the assembling ring, a rivet is installed abovethe right arc block, an assembling base is installed above the assembling ring, a positioning rod is installed below the assembling base, a fixing bolt is installed inside the assembling base, a sliding rod is installed above the assembling base, an eccentric block is installed above the sliding rod, and a sliding groove is formed inside the eccentric block. According to the eccentric bushing withthe eccentricity adjusting structure, by arranging the fixing bolt, the assembling base can be replaced, the position of the eccentric block can be adjusted through the sliding rod, and the eccentricity of the device can be accurately adjusted through cooperation of the fixing bolt and the sliding rod.

Description

technical field [0001] The invention relates to the technical field of eccentric workpieces, in particular to an eccentric sleeve with an eccentric adjustment structure. Background technique [0002] Eccentric workpiece refers to the workpiece whose outer circle and outer circle of the part or the outer circle and the axis of the inner hole are parallel and not coincident, and are offset by a distance. The distance between these two parallel axes is called the eccentricity, and the part that is eccentric between the outer circle and the outer circle is called the eccentric shaft or eccentric disc; the part that is eccentric between the outer circle and the inner hole is called the eccentric sleeve. In mechanical transmission, the rotary motion becomes Reciprocating linear motion or reciprocating linear motion into rotary motion is generally accomplished by using eccentric parts. [0003] The existing eccentric sleeves have narrow adaptability during use and cannot meet the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an eccentric sleeve with an eccentricity adjustment structure to solve the problem that the existing eccentric sleeve has narrow adaptability and cannot meet the adaptive adjustment of different eccentric errors in the use of the existing eccentric sleeve in the above-mentioned background technology. The problem is that the large amount of wear during use will cause changes in the positioning accuracy of the eccentric sleeve. When adjusting the eccentric amount of the eccentric sleeve, it is difficult to accurately adjust the eccentric amount. Small deviations will have a great impact on subsequent use and cannot be used very well. Meeting people's needs
