[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown, the utility model provides a CNC machine tool with an internal gas storage cylinder, comprising a machine tool body 1;

[0026] An air reservoir 2 is vertically suspended in the machine tool body 1, and an air inlet 21 for supplying air to the air reservoir 2 is provided on the air reservoir 2, and the air inlet 21 is connected to the air source through a pipeline;

[0027] The air inlet 21 of the air storage cylinder 2 is connected to the air source through a pipeline to inject compressed air, and a one-way valve is installed at the air inlet 21 to prevent the compressed air from flowing back and stabilize the air pressure in the air storage cylinder 2; the compressed air is filtered by the oil-water separator at the air source port to ensure the cleanliness of the air source.

[0028] An outlet 22 for outputting gas is provided at the bottom of the gas storage cylinder 2, and the outlet 22 is connected to the processing station through a pipeline;

[0029] Specifically,

[0030] The compressed air from the air outlet 22 of the air reservoir 2 is diverted through pipelines and can flow into different processing stations for processing. The air reservoir 2 of the utility model is connected to the tool magazine tool flipping station, the spindle tool beating station and the tool changing and air blowing station through pipelines, and solenoid valves are installed between the air reservoir 2 and the tool magazine tool flipping station, the spindle tool beating station and the tool changing and air blowing station.

[0031] The gas outlet 22 is placed at the lowest end of the gas cylinder 2. The gas in the gas cylinder 2 is discharged from the lowest end to the processing station. If there is water in the gas, it will be discharged outwards. Of course, the gas cylinder 2 continues to exhaust gas outwards at the lowest end. The water content in the gas is very small and will not affect the normal use of the machine tool. At the same time, the gas cylinder 2 can be kept dry, thereby increasing the service life of the gas cylinder 2.

[0032] If the air cylinder 2 is arranged horizontally in the prior art, the air outlet 22 is set on the air outlet cylinder 2, and a drain pipe is usually installed at the lowest end of the air cylinder 2. Since the oil and water in the compressed air are deposited in the air cylinder 2, the air cylinder 2 needs to be stopped and drained after being used for a period of time, which affects the utilization rate of the machine tool.

[0033] On the basis of the above-mentioned embodiment, a ball valve is installed at the connection between the gas outlet 22 and the pipeline to control the flow of gas in the pipeline.

[0034] On the basis of the above embodiment, a receiving chamber for the gas cylinder 2 is provided on one side of the machine tool body 1, and the gas cylinder 2 is detachably installed in the receiving chamber.

[0035] On the basis of the above embodiment, a longitudinal support frame 4 is arranged on the inner wall of the accommodating cavity, and the gas storage cylinder 2 includes a cylinder 23 and a group of hangers 24 arranged on the cylinder 23, and the hangers 24 are evenly distributed along the vertical direction of the cylinder 23. The hangers 24 are in surface contact with the longitudinal support frame 4 and are fastened to the longitudinal support frame 4 by bolts. The cylinder 23 is cylindrical, and the simple connection structure enables the cylinder 23 and the machine tool body 1 to be installed stably.

[0036] On the basis of the above embodiment, a cabinet door 3 is rotatably installed on the machine tool body 1 corresponding to the accommodating cavity, and the air storage cylinder 2 is built into the machine tool body 1 and provided with a cabinet door 3, which is a hidden structure and does not affect the overall appearance design of the machine tool.

[0037] In summary:

[0038] The utility model discloses a CNC machine tool with an air storage cylinder, wherein the air storage cylinder is arranged in a built-in manner relative to the machine tool, so that the overall air path and pipeline layout of the machine tool is neat and beautiful, and the stability of the air path pressure of the processing station is improved;

[0039] The air storage cylinder is arranged vertically, and the air outlet is placed at the lowest end of the air storage cylinder body. The air is continuously exhausted outward from the lowest end of the cylinder body, which can keep the air storage cylinder dry and increase the service life of the air storage cylinder.
