Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, in particular to a shock absorption mechanism and a numerical control machining center. Background Technique

[0002] For the Chinese patent document with the publication number CN213003747U, it discloses a buffer base for a numerical control machining center, which includes a support base and a support bottom plate. The number of the support bottom plates is four, and the four support bottom plates are respectively located at the four corners of the bottom of the support base. A shock absorption pad is fixedly connected to the bottom of the support bottom plate, and a support mechanism is arranged between the support bottom plate and the support base. For this buffer base for a numerical control machining center, when the machine tool located at the top of the support base is working, if vibrations occur, the support base will move up and down on the top of the support bottom plate through the support mechanism, causing the support rod to move up and down inside the fixed tube, and then causing the first spring to move up and down inside the fixed tube, and the second spring to move up and down inside the outer sleeve. Through the elastic action of the first spring and the second spring, the vibrations during the use of the machine tool can be reduced, and thus the shock absorption effect is achieved.

[0003] However, in the above scheme and the prior art, shock absorption pads are usually arranged on the base of the existing numerical control machining center to contact the ground to improve the shock absorption effect during the operation of the numerical control machining center. During the use process, the shock absorption pads need to be replaced in time due to wear with the ground. The wear degree of the side position of the shock absorption pad is more serious than that of the central position. When the side of the shock absorption pad is worn, the wear degree of the central position of the shock absorption pad is relatively low and it can still be used. Discarding the shock absorption pad at the central position that can still be used when the whole shock absorption pad is disassembled and replaced causes waste.
