Abstract
The invention discloses a spindle cooling structure, which is applied to a spindle of a machine tool. The spindle is arranged inside a spindle box; a bearing short sleeve is arranged on the spindle; and an annular cutting groove is arranged on the spindle box corresponding to the bearing short sleeve, so that an annular cavity is formed between the bearing short sleeve and the annular cutting groove. A cooling liquid inlet and a cooling liquid outlet are formed on the upper and lower parts of the annular cavity respectively; and a sealed rubber ring is arranged on the connecting part of the bearing short sleeve and the spindle box so as to guarantee the tightness of the annular cavity. In order to improve the cooling effect, a circulation loop is arranged between the cooling liquid inlet and the cooling liquid outlet. The cooling liquid of the loop flows more rapidly by arranging a circulating pump on the loop. The heat is generated and temperature rise happens when workpieces rotate at a high speed; the spindle box and the short sleeve are cooled by the circulating cooling liquid, so that the heat produced by the bearing is taken away; the temperature rise of the bearing is effectively reduced; and the service life of the spindle is prolonged.
Description
Technical field
The present invention 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.
Summary of the invention
The purpose of this invention is to provide the employed cooling structure of a kind of main shaft of numerical control machine tool, solve the problem of main shaft of numerical control machine tool cooling.
The objective of the invention 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 present invention 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 embodiment of the invention.
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.
