Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, fig. 2, fig. 4 and fig. 5, the cooling system for the main shaft of the machine tool working table of the present invention includes a brush net 1, a condensation nozzle 2, a vortex cooling pipe, an adjustable condensation flexible pipe 6, a regulating valve 3, an industrial gas source 4 and a connecting block 5.
The brush net 1 is arranged on the connecting block 5, the connecting block 5 is arranged on the outer side of the spindle motor, and the brush net 1 is arranged into a rectangle and surrounds the outer side of the spindle. The brush net 1 forms a rectangular closed space outside the main shaft to prevent metal chips from splashing during cutting work, and the metal chips can enter a chip cleaner along a through hole below the workbench under the action of self gravity, the inclined workbench and the movement of the main shaft; the brush net 1 also has the function of heat preservation. The brush net 1 is arranged on the connecting block 5 and is positioned outside the main shaft, so that the working state and the replacement of the main shaft, the cutter and the fixture inside the brush net can not be influenced. In other embodiments of the present invention, the brush net 1 may be arranged in a circular shape or other shapes.
The vortex refrigerating pipe is arranged on the connecting block 5. As shown in fig. 3, the vortex cooling pipe is provided with a cold end air outlet 7, an air inlet 8, a control valve 9 and a noise reduction silencer. The compressed air is injected into the turbine flow cooling pipe from the air inlet 8 and flows at a velocity of 1000000rmp toward the hot end (right side in fig. 3). When the hot air flows to the hot end, a small part overflows through the control valve 9, and the rest is forced to flow towards the other end and is discharged from the cold end air outlet 7 in the form of cooling air, and the temperature of the cooling air can be reduced to minus 40 ℃.
An adjustable condensation movable hose 6 is installed at a cold end air outlet 7 of the vortex refrigeration pipe, and the adjustable condensation movable hose 6 is connected with the condensation nozzle 2. The adjustable condensation flexible pipe 6 can rotate at any angle, and the condensation nozzle 2 can send cold air to a designated position. The air inlet 8 is connected with the industrial gas source 4. And the air inlet 8 of the vortex cooling pipe is provided with a regulating valve 3, and the regulating valve 3 is used for controlling the air inflow of the air inlet 8. When the industrial air source 4 is connected, high-pressure air flow enters the vortex refrigerating pipe through the air inlet 8, and is circulated in the vortex refrigerating pipe to obtain cooling air which is sprayed out of the condensing nozzle 2 through the adjustable condensing movable hose 6 to cool the surfaces of the cutter and the workpiece. The cooling air flows out and then is sprayed to the surfaces of the cutter and the workpiece in the form of gas mist. Due to the fact that the machining temperature of the cutter is high and the temperature of part of the surface of the cutter is high, cooling air can be instantly atomized and evaporated, and meanwhile the effects of cooling and no residual liquid are achieved.
The adjustable condensation movable hose 6 and the condensation nozzle 2 are positioned on the inner side of the hairbrush net 1, and the rectangular closed scrap-retaining heat-insulating hairbrush net 1 forms a better closed space in a processing area, so that the condensation nozzle 2 and the adjustable condensation movable hose 6 are positioned in the hairbrush net, and the position of the nozzle can be flexibly adjusted according to the positions of a cutter and a fixture. And the air is connected with a noise reduction silencer to reduce the noise of the environment. The cooling nozzle can also assist in removing fine debris left on the cut workpiece. Because the rectangular closed chip-blocking heat-preservation hairbrush net 1 is a better closed space in a processing area, the lower temperature in a certain area can be kept, the stable working temperature of a cutter and the surface temperature of a workpiece can be kept, and the service life of the cutter and the surface quality of the workpiece can be maintained.
When the cooling system of the main shaft of the machine tool workbench works, the position of the condensing nozzle 2 is firstly adjusted to be aligned with a cutter; and then an industrial air source 4 is opened, the air enters the vortex cooling pipe and becomes cold air, and the cold air is sprayed out from the condensing nozzle 2, so that the cutter and the workpiece are cooled.
The utility model discloses lathe workstation main shaft cooling system adopts vortex refrigeration pipe to convert highly-compressed air into low temperature air, cools down cutter and work piece, ensures operational environment, roughness and the life of cutter. The vortex refrigerating pipe has simple structure, convenient use and no maintenance. The low-temperature air can produce high-pressure aerial fog in the twinkling of an eye when meeting cutter and the work piece of high temperature, and high-pressure aerial fog can reduce the temperature on work piece surface simultaneously, reduces the heat altered shape, and high-pressure aerial fog can directly volatilize simultaneously and do not have the coolant liquid to remain.
The hairbrush net outside the condensing nozzle can form a relatively closed space area outside the end face of the main shaft, so that metal scraps are prevented from splashing, the temperature in the area is kept relatively stable, and the cooling effect on the cutter and the workpiece is enhanced.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
