[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 2 , the utility model embodiment includes:

[0017] A machine tool bearing cooling system is used for cooling a bearing 3 fixed on a screw rod 2 in a bearing seat 1, comprising an air source 4, an air dryer 5, an air filter 6, a stop valve 7, a pressure reducing valve 8, a speed control valve 9, a one-way valve 10, a vortex generator 11, an air outlet block 12 and a temperature detection module 13.

[0018] Among them, the air source 4, air dryer 5, air filter 6, stop valve 7, pressure reducing valve 8, speed control valve 9 and one-way valve 10 are connected in sequence through pipelines. The compressed air is filtered from the air source 4 through the air dryer 5 to prevent the water vapor from causing oxidation and rust of the transmission parts; then it passes through the air filter 6, which adopts a 5μm filter pore size to filter dust particles in the gas to avoid affecting the accuracy of subsequent components; the stop valve 7 is used to open and close the entire passage; the pressure reducing valve 8 and the speed control valve 9 can adjust the pressure and flow control according to the requirements of the cooling end; the one-way valve 10 ensures the consistency of the flow direction of the air source 4 and blocks the dust particles at the outlet from flowing back into the air path control element.

[0019] The air inlet end of the vortex generator 11 is connected to the one-way valve 10 through a pipeline, and the cold air end of the vortex generator 11 is connected to the air outlet block 12 through a pipeline. The air source 4 enters the vortex generator 11 and accelerates the rotation of the compressed air by utilizing the vortex effect and the energy separation principle. The outer layer of air generates heat due to friction, and the inner layer of air becomes cold. At the tail of the vortex generator 11, it is separated into a hot air flow and a cold air flow. The hot air flow is drawn out from the hot air end, and the cold air flow is sent from the cold air end to the air outlet block 12 to act on the bearing seat 1.

[0020] The air outlet block 12 is arranged in a square structure and has a semicircular contoured groove 121 which is concave in the center of the lower surface and corresponds to the outer surface of the bearing seat 1 , thereby ensuring uniform air distribution on the outer surface of the bearing seat 1 .

[0021] The outlet block 12 is provided with a horizontally distributed total air inlet hole 122 on the adjacent side of the bottom of the profiling groove 121, and the total air inlet hole 122 is connected to the cold air end of the vortex generator 11 through a pipeline; the outlet block 12 is provided with a plurality of branch air inlet holes 123 which are perpendicular to and connected to the total air inlet hole 122 and are evenly spaced and horizontally distributed on both end sides of the profiling groove 121; the outlet block 12 is provided with a plurality of air distribution holes 124 which are perpendicular to and correspondingly connected to the plurality of branch air inlet holes 123 and are distributed in a longitudinal array on the concave surface of the profiling groove 121, and the cold air flow acts evenly on the bearing seat 1 through the air distribution holes 124. The bearing seat 1 is cooled down under the action of the cold air flow, and the bearing 3 wrapped by the bearing seat 1 is cooled down through material conduction.

[0022] The air outlet block 12 is provided with fixing seats 126 with threaded holes 125 extending outwardly from both end sides of the contoured groove 121 for fixing and installing the air outlet block 12 .

[0023] The bearing seat 1 is also connected to a temperature detection module 13, and the temperature around the bearing 3 is controlled by the temperature detection module 13. When the temperature exceeds the preset range, the temperature detection module 13 gives a high temperature signal, and the on-off valve 7 of the gas circuit is powered on to open for cooling. When the temperature is lower than the preset temperature range, the temperature detection module 13 gives a low temperature signal, and the on-off valve 7 of the gas circuit is powered off and closed. As the bearing 3 rotates continuously, friction generates heat, and the cooling system continuously repeats the above cooling action to achieve the purpose of controlling the temperature rise of the bearing 3.

[0024] In summary, the machine tool bearing cooling system pointed out in the utility model is more energy-saving and environmentally friendly than traditional liquid cooling equipment, and is more economical and affordable while meeting the purpose of use control; it truly embodies cost reduction and efficiency improvement, and plays a positive and beneficial role in the promotion of the product in the market.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
