SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lathe main shaft cooling device to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a lathe main shaft cooling device, includes the main shaft, its innovation point lies in: the left and right sides of main shaft sets up the bearing, cup joint the cooling jacket between the bearing, set up helical structure's water-cooling passageway and air-cooled passageway in the cooling jacket respectively, the one end of water-cooling passageway is the inlet, and the other end is the liquid outlet, the one end of air-cooled passageway is the air inlet, and the other end is the gas outlet, a plurality of fumaroles are seted up to the below of water-cooling passageway, the fumarole is towards the main shaft.
Furthermore, the inner wall of the cooling jacket is convex, and a gap is reserved between the inner wall of the cooling jacket and the surface of the main shaft, and the gap is 1-2mm.
Furthermore, the water cooling channel and the air cooling channel are distributed in a staggered mode.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has simple structure and convenient use; the spindle is cooled by cooling water and cooling air, and the mode of combining water cooling and air cooling is adopted, so that the temperature rise of the spindle is effectively kept within a normal range, the service life of the machine tool spindle is ensured, and the spindle is simple in structure, convenient to machine, stable in performance and remarkable in effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals:
the device comprises a main shaft 1, a bearing 2, a cooling jacket 3, a water cooling channel 4, an air cooling channel 5 and an air injection hole 6.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, a machine tool spindle cooling device comprises a spindle 1, bearings 2 are arranged on the left side and the right side of the spindle 1, a cooling jacket 3 is sleeved between the bearings 2, a water cooling channel 4 and an air cooling channel 5 of a spiral structure are respectively arranged in the cooling jacket 3, one end of the water cooling channel is a liquid inlet, the other end of the water cooling channel is a liquid outlet, one end of the air cooling channel is an air inlet, the other end of the air cooling channel is an air outlet, a plurality of air injection holes 6 are arranged below the water cooling channel, and the air injection holes face the spindle. Specifically, through pouring into the cooling water into water-cooling channel 4, pour into cooling air into air-cooling channel 5 in to carrying out water-cooling and forced air cooling to main shaft 1, both intercombination improve cooling efficiency, cooling air is from jet orifice 6 blowout simultaneously, direct and main shaft 1 surface contact, further improved cooling efficiency, the temperature rise that effectively keeps the main shaft is in normal range, ensures the life of lathe main shaft, and its simple structure, processing convenience, stable performance, effect are showing moreover.
In this embodiment, the inner wall of the cooling jacket 3 is convex, and a gap is left between the inner wall and the surface of the main shaft, and the gap is 1-2mm. The gap can ensure that the cooling air is spread along the main shaft 1 to a certain extent, which is beneficial to cooling.
In this embodiment, the water cooling channel 4 and the air cooling channel 5 are distributed in a staggered manner, so that the water cooling channel and the air cooling channel can be used normally.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
