Auxiliary positioning device of rod piece and using method thereof

Abstract

The invention relates to an auxiliary positioning device of a rod piece. The auxiliary positioning device comprises a height-adjustable frame body, a fixing seat, a ring piece and a clamping piece, and the frame body is arranged on the ground; the fixing seat is mounted at the top of the frame body and can move back and forth in the direction perpendicular to the rod piece; the ring piece is installed on the fixing seat and can rotate around the axis direction, the exposed part of the rod piece is sleeved with the ring piece, and the center of the ring piece coincides with the center of the rod piece by adjusting the height of the frame body; and the clamping piece is installed on the ring piece and used for clamping the rod piece, the rod piece is clamped through the clamping piece so asto fix and support the exposed part of the rod piece, and the rod piece can drive the ring piece and the clamping piece to rotate together when rotating. According to the auxiliary positioning device,the problem that the rod piece machining precision is low is effectively solved, the auxiliary positioning device and the rod piece rotate synchronously, the rod piece can be prevented from shaking,the influence on the rod piece machining precision can be reduced, the rod piece cannot be damaged, and the machining quality can be guaranteed.

Description

technical field [0001] The invention relates to the field of parts processing, in particular to an auxiliary positioning device for rods. Background technique [0002] With the development of the national machinery industry, the parts processed by CNC machine tools are various, and the requirements for the machining accuracy of parts are getting higher and higher. In the actual processing of long rods, due to the long rods, a long part is located On the outside of the CNC machine tool, during the process of rotating the rod, the rod will vibrate up and down due to the action of gravity, thus affecting the machining accuracy. At present, in order to avoid this situation, the clamp is usually used to slightly clamp the rod. Graphite is applied between the tensioner and the rod to reduce the friction between the two, but this method still has an impact on the machining accuracy when the rod rotates rapidly, and may even cause damage to the rod such as bending and twisting . ...
