DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] For example, see Figure 1-3A protective frame for a CNC machine tool comprises a top plate 1, a telescopic rod 2 is slidably connected to the top plate 1, a side plate 3 is fixedly connected to the telescopic rod 2, a cooling device 4 is arranged on the top plate 1, a temperature control component 5 is arranged on the top plate 1, the cooling device 4 comprises a shell 41, the shell 41 is fixedly connected to the lower outer wall of the top plate 1, a motor 42 is fixedly connected to the top of the top plate 1, the output shaft of the motor 42 passes through the top plate 1 and the inner wall of the shell 41, the output shaft of the motor 42 is fixedly connected to a rotating wheel 43, the rotating wheel 43 is fixedly connected to an extrusion wheel 44, and the inside of the shell 41 is movably connected to a soft The hose 45 is made of soft rubber. By setting the material of the hose 45, it is ensured that the hose 45 has a certain deformation ability, so as to achieve the expected effect. The hose 45 is arranged in the area between the inner wall of the shell 41 and the rotating wheel 43, and the distance between the squeezing wheel 44 and the inner wall of the shell 41 after rotating to the closest position to the shell 41 is exactly equal to twice the thickness of the hose 45. By setting the position of the hose 45 and the closest position of the squeezing wheel 44 to the shell 41, it is ensured that the squeezing wheel 44 can squeeze the hose 45, so as to achieve the expected effect. The hose 45 is connected to the water storage tank 46. The wheel 43 is fixedly connected with a perforated hollow wheel 47, and one end of the hose 45 away from the water storage tank 46 is fixedly connected with an annular slide, and the annular slide is slidably connected to the inner wall of the perforated hollow wheel 47. By setting the annular slide, the end of the hose 45 can be fixed inside the perforated hollow wheel 47, and it is ensured that the water flow does not flow out through the through hole on the perforated hollow wheel 47. The end of the hose 45 away from the water storage tank 46 passes through the inner wall of the perforated hollow wheel 47. The shape of the perforated hollow wheel 47 is a shape in which a small diameter ring is connected to a large diameter perforated hollow cylinder. The shape of the perforated hollow wheel 47 ensures that the perforated hollow wheel 47 can be connected to the rotating wheel 43 without affecting the watering effect. The rotating wheel 43 is driven to rotate by the motor 42, thereby driving the extrusion wheel 44 to rotate, and the extrusion wheel 44 squeezes the hose 45 while rotating, so that the liquid inside the hose 45 is squeezed and sprayed out while generating negative pressure water absorption, and the perforated hollow wheel 47 is driven to rotate by the rotating wheel 43, so that the liquid flowing into the perforated hollow wheel 47 from the hose 45 flows out from the through hole opened on the perforated hollow wheel 47 under the action of centrifugal force, thereby achieving the effect of spraying water for cooling.
[0020] When in use, the staff first adjusts the telescopic length of the telescopic rod 2 so that the telescopic rod 2 can drive the side plate 3 and the top plate 1 to be in the external area of the CNC machine tool. When the adjustment is completed, the staff starts the CNC machine tool. When the CNC machine tool generates heat during operation, when the heat is too large, the switch of the motor 42 of the temperature control component 5 is turned on, so that the motor 42 drives the rotating wheel 43 to rotate, and the rotating wheel 43 drives the extrusion wheel 44 to rotate. During the rotation process, the extrusion wheel 44 contacts and squeezes the hose 45, causing the hose 45 to deform, and during the extrusion process, drives the liquid inside the hose 45. The water moves and flows out through the end portion of one side close to the punched hollow wheel 47. At the same time, negative pressure is generated inside the hose 45 during the squeezing process, thereby absorbing the water through the inside of the water storage tank 46. After the water enters the punched hollow wheel 47 through the hose 45, the punched hollow wheel 47 rotates driven by the impeller 43, and the water flows out through different through holes opened below the punched hollow wheel 47 under the combined action of the centrifugal force generated by the rotation of the punched hollow wheel 47 and gravity, and falls on the outer wall of the CNC machine tool below, so that the outer wall of the CNC machine tool contacts the water, thereby achieving a cooling effect on the CNC machine tool.
[0021] For example 2, please refer to Figure 1-4 On the basis of the first embodiment, the temperature control component 5 includes a fixing plate 51, which is fixedly connected to the lower outer wall of the top plate 1, and an airbag 52 is fixedly connected to the fixing plate 51. The material of the airbag 52 is polyamide fiber, and the inside of the airbag 52 is coated with a silicone rubber coating. The setting of the material of the airbag 52 ensures that the airbag 52 has a certain high temperature resistance and ensures that the airbag 52 will not be damaged due to excessive heat. A control board 53 is slidably connected to the inner wall of the fixing plate 51, and a switch of the motor 42 is provided on the lower outer wall of the top plate 1. The control board 53 and the top plate 1 are elastically connected by a spring 54. When the temperature rises, the airbag 52 expands, thereby pushing the control board 53, so that the control board 53 moves upward to squeeze the switch of the motor 42, so that the motor 42 is turned on, so as to achieve the effect of automatically starting the cooling device by temperature rise.
[0022] During use, on the basis of Example 1, when the temperature of the CNC machine tool rises, the gas inside the airbag 52 expands due to the heat, thereby compressing the control board 53, so that the control board 53 slides upward after being squeezed upward, and squeezes the switch of the motor 42 after the upward movement distance reaches a certain value, so that the motor 42 is turned on. When the temperature of the CNC machine tool drops under the operation of the cooling device 4, the gas inside the airbag 52 contracts. At this time, the control board 53 moves downward under the action of the rebound force of the spring 54, thereby moving away from the switch of the motor 42, so that the cooling device 4 is automatically closed.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
