Abstract
Disclosed is a machine tool principal shaft bearing cooling device. A bearing sleeve is installed between a front support bearing and a support body of the principal shaft; a spiral cooling groove is processed on the outer circle of the bearing sleeve; a cooling liquid inlet and a cooling liquid outlet are processed on the support body; and the spiral cooling groove is communicated with the cooling liquid inlet and the cooling liquid outlet on the support body. When passing through the spiral cooling groove on the bearing sleeve, the cooling liquid takes away the heat and cools the bearing sleeve and furthermore reduces the temperature of the principal shaft bearing and the principal shaft, thus reducing the deformation caused by temperature rise of the principal shaft and improving the machining precision and the surface quality of the workpiece. The machine tool principal shaft bearing cooling device reduces the deformation of the principal shaft and improves the machining precision and the surface quality of the workpiece.
Description
Technical field:
The utility model relates to a kind of main shaft bearing cooling device.
Background technology:
At present existing machine tool mainshaft bearing does not have cooling device, and along with the high speed rotation of main shaft, the main shaft bearing temperature can be along with rising, and main shaft is at axial direction generation micro-deformation, influences the end face run-out of main shaft and then influences the precision of processing work.
Summary of the invention:
The utility model purpose is to overcome the prior art deficiency, and a kind of effective reduction main shaft bearing temperature is provided, and solves existing main shaft bearing temperature and raises the problem that the processing work precision is not high.
For achieving the above object, technical solution of the present utility model is: between block bearing and the supporting mass bearing holder (housing, cover) has been installed before the main shaft, process the spiral cooling bath on the outer peripheral face of bearing holder (housing, cover), being processed with cooling fluid on the supporting mass imports and exports, spiral cooling bath on the bearing holder (housing, cover) is communicated with cooling fluid import and export on the supporting mass, cooling fluid is taken away heat cooling bearing sleeving temperature during the spiral cooling bath and then is reduced main shaft bearing and main shaft temperature on by bearing holder (housing, cover), reduce that main shaft temperature rises and the distortion that brings, improved the precision and the surface quality of processing work.
The beneficial effects of the utility model are to reduce spindle deformation, improve processing work precision and surface quality.
Description of drawings:
Below in conjunction with accompanying drawing the utility model embodiment is done to further specify.
Accompanying drawing the utility model structural representation.
Among the figure: the 1----ring flange; The 2----bearing holder (housing, cover); 3----cooling fluid inlet; The 4----main shaft; The 5----main shaft bearing; The 6----cooling liquid outlet; The 7----supporting mass; 8----spiral cooling bath.
The specific embodiment:
In the accompanying drawings, main shaft bearing 5 is installed on the main shaft 4, between main shaft bearing 5 and supporting mass 7, bearing holder (housing, cover) 2 has been installed, spiral cooling bath 8 is arranged on the outer peripheral face of bearing holder (housing, cover) 2, be processed with cooling fluid inlet 3 and cooling liquid outlet 6 on the supporting mass 7, external refrigeration liquid flows into by cooling fluid inlet 3, flow out by cooling liquid outlet 6, cooling fluid inlet 3 and cooling liquid outlet 6 on spiral cooling bath 8 and the supporting mass 7 are communicated with, and ring flange 1 is installed in the bearing holder (housing, cover) 2, is used to adjust main shaft bearing 5 precision.
Embodiment: before main shaft 4 rotations, adjust main shaft bearing 5 precision by ring flange 1.Main shaft 4 is in the process of high speed rotary cutting, and external refrigeration liquid is by the inlet of the cooling fluid on the supporting mass 73 spiral cooling baths 8 that enter on the bearing holder (housing, cover) 2, and coolant temperature raises.The cooling that temperature raises is flowed out supporting mass 7 by the cooling liquid outlet on the supporting mass 76.Like this, just can reduce the temperature of main shaft 4, reduce main shaft 4 distortion, improve processing work precision and surface quality.
