Gravity center follow-up balance compensating device of floor type boring and milling machine

Abstract

The invention relates to a gravity center follow-up balance compensating device of a floor type boring and milling machine. The floor type boring and milling machine comprises a ram and a ram seat; the gravity center follow-up balance compensating device comprises a ram balance compensating device; the ram balance compensating device comprises a guide rail arranged on the upper part of the ram seat, a slide block matched with the guide rail and a rack; the rack is fixedly connected with the ram and positioned on the gravity center line vertical to the motion direction of the ram; and the rack is connected with the slide block by screw threads. The device can eliminate deflection error generated due to dead weight when the ram is extended, can compensate lowering error generated by integral gravity center shift of the ram seat, has simple structure and low cost, is easy to implement and control, and greatly improves various precision indexes compared with those of the lowering error which is not compensated.

Description

Technical field [0001] The invention belongs to the technical field of devices for avoiding or reducing unbalanced forces such as caused by motion, and particularly relates to a center of gravity compensation device suitable for large-scale floor milling and boring machines. Background technique [0002] Large-scale CNC floor milling and boring machine is mainly used for precision boring and milling of large and heavy parts. It can also perform drilling, reaming, thread cutting, groove cutting and three-dimensional curved surface processing. It is widely used in the machinery manufacturing industry. Important metal cutting equipment. [0003] In the development of large-scale CNC floor milling and boring machines, the center of gravity offset compensation technology of the ram and headstock has always been a key technology on floor milling and boring machines at home and abroad, and the technical methods adopted are also diverse. [0004] In the prior art, there are two main methods...

AI Technical Summary

Problems solved by technology

[0006] The technical problem solved by the present invention is that the center of gravity balance adjustment device of the machine tool cannot simultaneously adjust the center of gravity and balance the machine due to the fact that the existing technology cannot make the center of gravity balance compensation device of the large floor milling and boring machine have the advantages of stability and economy. And the problem of reducing the cost and expenditure requirements, and then provides a center of gravity follow-up balance compensation device for floor milling and boring machines
