Damping structure of drilling machine supporting seat

Abstract

The invention relates to a damping structure of a drilling machine supporting seat. The damping structure comprises the supporting seat which comprises wall plates of two-layer structures, retaining plates are fixedly connected at two ends of the wall plates, a damping rib is welded between the wall plates, the wall plates and the damping rib are not completely welded and can slide mutually, the section of the damping rib is of a curved structure, a first filling cavity and a second filling cavity are formed between the damping rib and the wall plate, two ends of the damping rib are provided with vertical plates respectively, the vertical plates are fixedly connected with the retaining plates, a third filling cavity is formed between the two ends of the damping rib and the wall plates by the aid of the vertical plates, and buffering padding is arranged in the first filling cavity, the second filling cavity and the third filling cavity respectively. A two-layer wall plate structure and a welding structure with high damping performance are adopted, so that vibration of a drilling machine is effectively reduced, drilling accuracy is improved. The damping structure has the advantages of simple structure and good damping effect.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a support seat of a drilling machine. Background technique [0002] The support base is the foundation of the drilling machine, and its structural stability directly affects the drilling accuracy. When the existing drilling machine (especially the rocker drilling machine) is working, the support seat will vibrate to a certain extent, which will cause the drill bit to vibrate. Generally, the vibration can be reduced by adjusting the drilling speed or changing the fixing method of the workpiece Due to the deviation brought about, it can only meet the processing of parts with low precision requirements and large hole diameters, and cannot realize the finishing of precision parts, and its operation is cumbersome, the drilling accuracy is low, and the work efficiency is low. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the existing ...
