Description
Technical Field
The utility model relates to the field of machine tool equipment, in particular to a gantry machining center vertical ram with vibration suppression capability.
Background
With the rapid development of the equipment manufacturing industry, the requirement on the machining master machine is remarkably improved in order to meet the machining requirements of various industries as the machine tool industry of the equipment manufacturing machining master machine. The existing casting vertical ram is characterized in that a main shaft is arranged on a main shaft sleeve of the vertical ram, a single-layer wall structure is arranged on the main shaft sleeve, the main shaft is fixed at the lower end of the vertical ram, the ram is only fixedly connected with a main shaft flange, when a machine tool is used for machining and cutting, particularly in the cutting process of high-speed rotation, the stress of the main shaft is transmitted to the vertical ram, and the vertical ram generates vibration, noise and the like, so that the machining precision of the machine tool and the surface quality of a machined part are influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of the prior art, and provides a vertical ram of a gantry machining center with vibration suppression capability, which can solve the problems of vibration, noise and the like of the vertical ram in the prior art, improve the machining precision of a machine tool and improve the surface quality of a machined part.
The technical scheme for solving the technical problems is as follows: the vertical ram of the gantry machining center with the vibration suppression capability comprises a vertical ram spindle sleeve and a spindle arranged in the vertical ram spindle sleeve, and is characterized in that the vertical ram spindle sleeve is of a double-side-wall sleeve structure, the thickness of the inner wall of the vertical ram spindle sleeve is larger than that of the outer wall of the vertical ram spindle sleeve, the upper end and the lower end of the outer wall of the vertical ram spindle sleeve are welded with the inner wall of the vertical ram spindle sleeve through a closed ring to form a sandwich space, and damping media are filled in the sandwich space.
Further, the damping medium is made of steel, lead or tungsten particles.
Furthermore, the vertical ram body is made of Q355A material.
Furthermore, a threaded hole for filling damping particles is reserved in the closed ring, and a plug is arranged at the threaded hole.
Further, the inner wall is 20mm thicker than the outer wall.
The utility model has the beneficial effects that: according to the utility model, the vertical ram spindle sleeve with a double-side-wall structure is arranged, a double-layer sandwich space is formed between the inner wall and the outer wall of the vertical ram spindle sleeve through sealing and closed-loop welding, damping media such as large damping steel, lead or tungsten particles are filled in the double-layer sandwich space, the natural frequency of the vertical ram is changed, and the system damping ratio of the vertical ram is also changed. The problems of vibration, noise and the like generated by the vertical ram can be reduced, the machining precision of the machine tool is improved, and the surface quality of a machined part is improved.

in the figure: 1. the ram comprises a main shaft, 2 vertical ram main shaft sleeves, 3 inner walls, 4 outer walls, 5 sandwich spaces, 6 damping media, 7 closed rings and 8 plug heads.
Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the utility model.
As shown in fig. 1-3, the main body of the gantry machining center vertical ram with vibration suppression capability of the present embodiment is formed by welding Q355A material, and includes a vertical ram spindle sleeve 2 and a spindle 1 installed therein;
the vertical ram spindle sleeve 2 is of a double-side-wall sleeve structure, the thickness of the inner wall 3 of the vertical ram spindle sleeve is 28mm, the thickness of the outer wall 4 of the vertical ram spindle sleeve is 8mm, the inner side of the vertical ram spindle sleeve is a sleeve with a thicker wall thickness, the rigidity of the spindle sleeve is ensured, the outer side of the vertical ram spindle sleeve is a sleeve with a thinner wall thickness, and a double-layer sandwich spindle sleeve is formed inside and outside the vertical ram spindle sleeve; the upper end and the lower end of the outer wall 4 are welded with the inner wall 3 through a closed ring 7 to form a sandwich space, damping media 6 are filled in the sandwich space, specifically steel, lead or tungsten particles are adopted, a threaded hole for filling the damping particles is reserved on the closed ring 7, and a plug 8 is arranged at the threaded hole.
The inner and outer walls 3 and 4 of the main shaft are welded and formed by the sealing ring 7 in the main shaft sleeve, threaded holes for filling damping particles are reserved in the sealing ring, the damping particles are filled after the welding blank is formed and tempered, and the sealing ring is sealed by a plug 8 after the filling. When a machine tool is used for cutting, particularly in the cutting process of high-speed rotation, the vertical ram spindle sleeve of the double-side-wall sleeve with the double-layer sandwich structure is adopted and filled with large damping steel, lead or tungsten particles, so that the natural frequency of the vertical ram can be changed, and the system damping ratio of the vertical ram can also be changed, thereby reducing the problems of vibration, noise and the like of the vertical ram, improving the processing precision of the machine tool and improving the surface quality of a processed part.
