Problems solved by technology

[0003] The purpose of the present invention is to provide a method for adjusting the center of gravity of the workpiece in a large range, so as to overcome the problems that the current steady frame is difficult to adjust the force when clamping the workpiece, and it is easy to cause the workpiece to loosen and form an ellipse on the end face of the workpiece or lock due to excessive force. And the problem of the small adjustment range of the conventional steady frame

Abstract

The invention discloses a method for adjusting the gravity center of a workpiece in a large range. An installation base (8) is included. A center rest body (9) is arranged on the installation base (8). Three clamping grooves (12) are evenly formed in the center rest body (9). A fixing bolt (13) is arranged on the sidewall of each clamping groove (12). An adjusting barrel (10) is installed in each clamping groove (12). Top wheels are installed at the ends, located on the inner side of the center rest body (9), of the three adjusting barrels (10). According to the method, frictional force of the workpiece and the center rest body is converted into rolling frictional force, and the condition that the workpiece is locked is reduced. Meanwhile, acting force between the top wheels and the workpiece can be adjusted through driving of rotating plates, so that the workpiece is stressed evenly. The relative position relation between the adjusting barrels and the center rest body can be changed through the fixing bolts on the clamping grooves, so that the application range of center rests of the same model is enlarged.

Description

technical field [0001] The invention relates to an auxiliary device in the machining and cutting process, in particular to a method for adjusting the center of gravity of a workpiece in a wide range. Background technique [0002] In the machining industry, especially in the cutting of slender workpieces, steady rests are often used. The center frame is an auxiliary device for radially supporting the rotating workpiece during machining. When machining slender shaft parts, the length-diameter ratio L / D>15, in order to prevent the workpiece from being bent and deformed by the radial cutting force, commonly used The center frame is used as an auxiliary support to increase the rigidity of the workpiece. During processing, there is no relative axial movement with the workpiece, the center frame should be fixed on the bed, rough alignment with a scribe, after applying lubricating oil, the bed rotates at low speed to adjust the speed according to the thickness and weight of the ...
