Abstract
A main shaft cooling structure is applicable to a main shaft of a machine tool, wherein, the main shaft is installed inside a main shaft box, a bearing short sleeve is mounted on the main shaft, a ring cutting groove corresponding to the bearing short sleeve is arranged on the main shaft box in a way that the bearing short sleeve and the ring cutting groove form a ring-shaped cavity, a coolant inlet and a coolant outlet are respectively arranged at the upper and the lower parts of the ring-shaped cavity, and a sealing ring rubber ring is installed at the joint of the bearing short sleeve and the main shaft box to prevent the ring-shaped cavity from leakage. In order to improve cooling performance, a circulation pipeline can be arranged between the coolant inlet and the coolant outlet. To enable coolant in the pipeline to move faster, a circulation pump can be added to the circulation pipeline. When rotating at a high speed, a work piece can generate heat, and temperature rise occurs. Cooling the main shaft box and the short sleeve with circulating coolant can take away heat generated by a bearing, thereby effectively minimizing the temperature rise of the bearing and prolonging the service life of the main shaft.
Description
Technical field
The utility model relates to the spindle cooling structure on a kind of Digit Control Machine Tool.
Background technology
Various lathes all can produce a large amount of heats in the process of running, if heat can not distribute the service life of the equipment that will have a strong impact on timely.So present employed equipment has various cooling systems, cooling structure etc.
The utility model content
The purpose of this utility model provides the employed cooling structure of a kind of main shaft of numerical control machine tool, solves the problem of main shaft of numerical control machine tool cooling.
The purpose of this utility model is to be achieved through the following technical solutions:
Spindle cooling structure, be applied on the machine tool chief axis, described main shaft is installed in main spindle box inside, the short cover of bearing is installed on the main shaft, corresponding described bearing weak point is enclosed within a ring cutting groove is set on the described main spindle box, makes the short cover of bearing form an annular housing with described ring cutting groove, is respectively arranged with cooling fluid inlet and cooling liquid outlet in the upper and lower of described annular housing, junction at short cover of bearing and main spindle box is equipped with the sealing ring cushion rubber, to guarantee the sealing of annular housing.
For improving cooling effect, a circulation line can be set between the cooling fluid entrance and exit, for the coolant flow that makes pipeline is more rapid, can on pipeline, set up a circulating pump again.
Can produce the heat temperature rise during Work piece high-speed rotation,, the heat that bearing produces can be taken away, reduce the temperature rise of bearing effectively, prolong the service life of main shaft with circulating cooling liquid cooling main spindle box and short cover.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of the described spindle cooling structure of the utility model embodiment.
Fig. 2 is an A place partial enlarged drawing among Fig. 1.
Among the figure:
1, main shaft; 2, main spindle box; 3, the short cover of bearing; 4, annular housing; 5, sealing ring cushion rubber; 6, cooling fluid inlet; 7, cooling liquid outlet.
The specific embodiment
Shown in Fig. 1-2, spindle cooling structure, be applied on the machine tool chief axis 1, described main shaft 1 is installed in main spindle box 2 inside, the short cover 3 of bearing is installed on the main shaft 1, the short cover 3 of corresponding described bearing is provided with a ring cutting groove on described main spindle box 2, make the short cover 3 of bearing form an annular housing 4 with described ring cutting groove, be respectively arranged with cooling fluid inlet 6 and cooling liquid outlet 7 in the upper and lower of described annular housing 4, junction at short cover 3 of bearing and main spindle box 2 is equipped with sealing ring cushion rubber 5, to guarantee the sealing of annular housing.
Be to improve cooling effect, can cooling fluid enter the mouth 6 and export 7 between a circulation line is set, for the coolant flow that makes pipeline is more rapid, can on pipeline, set up a circulating pump again.
Can produce the heat temperature rise during Work piece high-speed rotation,, the heat that bearing produces can be taken away, reduce the temperature rise of bearing effectively, prolong the service life of main shaft with circulating cooling liquid cooling main spindle box and short cover.
