Abstract
The utility model relates to a coaxial degree regulator, belonging to an experimental device of material mechanics. A flat joint seat is fixedly connected with a ball joint seat, a flat joint is arranged in the flat joint seat, a ball joint is arranged in the ball joint seat, and a pressure spring is arranged between the flat joint and the ball joint; a threaded hole 1 is opened on the quarter position at the outer circle face of the flat joint seat, and a holding screw 1 is arranged in the threaded hole 1 and is connected with the flat joint in a propping manner; a threaded hole 2 is opened on the quarter position at the outer circle face of the ball joint seat, and a holding screw 2 is arranged in the threaded hole 2 and is connected with the ball joint in a propping manner; an internal thread 1 is arranged on the ball joint; and an internal thread 2 is arranged below the flat joint. The coaxial degree regulator has the advantages of novel structure, high regulating precision, convenient utilization and compact structure. The coaxial degree regulator can satisfy the requirements specified by experimental methods and experimental machine standards home and abroad.
Description
Technical field
The utility model belongs to materials mechanics experimental device technique field, can realize the adjusting of the right alignment of lower chuck.
Background technology
The right alignment regulator is to be used for universal testing machine, a kind of annex of right alignment between lower chuck in the adjusting.
In the tension test of material, last lower chuck is eccentric can to produce bending strain or stress, and yield characteristic changes, and the material with obvious yield situation is become so obviously and yield strength changes; The material gauge of no remarkable yield state is decided disproportional extension strength (R
P) time, curve offset R
PJust produce error.So the right alignment of upper and lower chuck is one of key factor that influences stretch test result.The right alignment of upper and lower chuck is by the cumulative limit decision of the physical dimension and the form and position tolerance of many parts itself such as the moving beam of collet body, pitman shaft, jaw, slide plate and the main frame of two chucks, entablature, work top, column, leading screw.Therefore, only depending on the machining precision of part to control right alignment is suitable difficulty.So it is necessary being equipped with an elimination cumulative errors device on testing machine.
Summary of the invention
The utility model provides a kind of right alignment regulator, and the difficulty that only depends on the machining precision control right alignment of part to exist with solution is big, weak effect, the inaccurate problem of result.Technical solutions of the utility model are: flush headstock and fixedly connected with the spherojoint seat, plain adapter is positioned at and flushes headstock, and spherojoint is positioned at the spherojoint seat, and in the middle of this plain adapter and the spherojoint stage clip is arranged; Flush on the headstock outer circumference surface quartern position and have threaded hole one, holding screw one is housed in this hole, and with the plain adapter apical grafting; The spherojoint seat outer circumference surface quartern also has threaded hole two on the position, and holding screw two is housed respectively in this hole, and with the spherojoint apical grafting; Internal thread one is arranged on the spherojoint; There is internal thread two the plain adapter below.
The internal thread one of spherojoint links with the testing machine load sensor during use; The internal thread two and the upper grip of plain adapter link.Flush on the headstock outer circumference surface quartern position and have threaded hole one, holding screw two is housed in the hole, the plain adapter that its rotation can promote to connect upper grip moves; Equally, four holding screws two on the spherojoint seat, can make the spherojoint seat is centroclinal with the centre of sphere, reaches the purpose that upper grip turns an angle.
The utility model advantage is: novel structure.Can compensate machining error; The chuck center line and load axis and be adjusted to consistently,, correspondingly align the adjusting that horizontal level or angle can realize right alignment according to the shown side-play amount of detector and direction with the supporting use of mechanical type right alignment detector.The degree of regulation height, easy to use, compact conformation.Regulating chuck centerline angles degree scope is-3 °～+ 3 °, the horizontal level range of adjustment is-5～+ 5mm, can satisfy the requirement of domestic and international test method and testing machine standard code.
