Description

Technical Field

[0001] This utility model relates to the field of cooling technology for CNC machine tool control cabinets, and in particular to an active cooling circulation structure for CNC machine tool control cabinets. Background Technology

[0002] The CNC machine tool control cabinet is the core control unit and power supply hub of the CNC machine tool. It integrates the electrical control system, CNC system, drive system, and auxiliary control modules. By receiving and processing instructions and driving the execution components, it achieves high-precision and automated control of the machine tool machining process. In order to maintain the normal operation of electrical equipment, a heat dissipation device is usually installed inside the cabinet. There is a type of cabinet air conditioner on the market for cooling CNC machine tool control cabinets. Its core principle is to use the phase change cycle of refrigerant to forcibly transfer the heat inside the control cabinet to the external environment, while ensuring that the air inside the cabinet is isolated from the outside. The cabinet air conditioner uses an internal fan to draw hot air into the air conditioner evaporator. The low-temperature refrigerant in the evaporator absorbs heat and evaporates into a gaseous state, which rapidly reduces the temperature of the air inside the cabinet. The cooled air is then sent back into the control cabinet, realizing the active cooling cycle of the CNC machine tool control cabinet.

[0003] In existing technologies, when an air conditioner is installed in the control cabinet of a CNC machine tool for active cooling circulation, an air inlet window is set on the outer shell of the air conditioner away from the cabinet. However, dust and fumes are often generated during the machining process of some CNC machine tools. The air conditioner, which is close to the CNC machine tool, is prone to internal pollution due to the air intake, which affects the stable operation of the active cooling circulation of the CNC machine tool control cabinet. We propose an active cooling circulation structure for CNC machine tool control cabinets. Utility Model Content

[0004] The main objective of this invention is to provide an active cooling circulation structure for CNC machine tool control cabinets. An air intake mechanism is installed at the air conditioner body of the cabinet. An extended duct can flexibly adapt to the distance from the control cabinet to the outdoor area of ​​the factory. A conical filter and an inner frame ring with filter discs, combined with a fan, provide dual filtration and air intake, thereby introducing clean air to a square guide hood. This square guide hood covers the air intake of the air conditioner body, ensuring clean air supply. This effectively prevents the air conditioner body from drawing in fumes and dust generated during CNC machine tool processing, ensuring stable active cooling circulation for the CNC machine tool control cabinet. This improves the reliability of the cooling system in complex processing environments and effectively solves the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An active cooling circulation structure for a CNC machine tool control cabinet includes an air conditioning unit and an air intake mechanism. The air intake mechanism includes a square guide cover, a tail tube, an extension tube, a connecting ring, a fan, symmetrical branch pipes, a connector, a back frame cover, and a conical filter. A square guide cover is installed at the outer air intake of the air conditioning unit. A tail tube, which is integrally formed on the outer surface of the square guide cover and fitted into the extension tube, is installed at the outer opening of the extension tube away from the square guide cover. A connecting ring is fitted inside the extension tube on one side of the fan. A conical filter is welded into the annular hole of the connecting ring and extends into the extension tube. A symmetrical branch pipe is integrally formed on the outer surface of the extension tube between the fan and the tail tube. A connector is inserted into one group of the symmetrical branch pipes. A back frame cover is screwed onto the outer surface of the remaining pipe of the symmetrical branch pipe away from the connector.

[0006] Furthermore, a recessed stepped annular groove is provided at the outer opening of the extended conduit away from the tail insert, and a lap ring is fitted inside the recessed stepped annular groove; By adopting the above technical solution, the lap ring can be clamped in the concave annular groove of the extension catheter.

[0007] Furthermore, the bottom of the cone filter screen is welded with a core frame disc of an inner frame ring through a riser, and filter screen pieces are welded between the inner frame body and the ring body of the inner frame ring. By adopting the above technical solution, the inner frame ring can carry the filter screen to form a two-stage filtration structure in the extension duct behind the cone filter screen, reducing the amount of dust and fumes entering the extension duct.

[0008] Furthermore, the extended guide tube on the outer side of the lap ring is symmetrically welded with an upper clamping plate and a support plate, and the surface of the upper clamping plate is provided with mounting holes for cooperating with the fan screw-on mounting bolts, and the fan housing is pressed on the surface of the support plate. By adopting the above technical solution, the air outlet of the fan can be blocked at the air inlet of the extension duct, and then the mounting plate of the fan can be locked to the upper clamping plate with bolts, while the fan casing can be supported by the support plate.

[0009] Furthermore, the outer sides of the insert tube and the tail insert of the insert connector are symmetrically fitted with sealing rings, and the diameters of the insert tube and the tail insert of the insert connector are the same. The diameter of the other end of the insert connector away from the insert tube is the same as the diameter of the extension conduit. By adopting the above technical solution, the head tube and tail tube of the insert pipe can be sealed and inserted into the extension conduit or symmetrical branch pipe with the help of the sealing ring. At the same time, the tail tube of another set of square guide covers can be inserted into the pipe opening of the other end of the insert pipe away from the symmetrical branch pipe, so as to facilitate the supply of air to another set of electrical cabinet air conditioners. After the back frame cover of the symmetrical branch pipe is unscrewed, the remaining square guide covers can be connected with the insert pipe, thereby supplying air to multiple sets of electrical cabinet air conditioners.

[0010] Furthermore, a frame is welded to the housing of the air conditioner body near its own air inlet, and the frame is embedded in a square guide cover. By adopting the above technical solution, the main body of the air conditioner cabinet is sealed with a square guide cover embedded in the frame to prevent dust and smoke impurities from entering the contact surface between the square guide cover and the main body of the air conditioner cabinet.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model incorporates an air intake mechanism at the main body of the air conditioner cabinet. An extended duct allows for flexible adaptation to the distance from the control cabinet to the outdoor area of ​​the factory. A conical filter and an inner frame ring with filter discs, combined with a fan, provide dual filtration to introduce clean air into a square guide hood. This square guide hood covers the air intake of the air conditioner cabinet, effectively preventing the air conditioner cabinet from drawing in fumes and dust generated by CNC machine tool processing. This ensures the air conditioner cabinet provides stable active cooling circulation to the CNC machine tool control cabinet, improving the reliability of the cooling system in complex processing environments. Furthermore, the extended conduit has many symmetrical branch pipes on its outer side, which can be connected to the back frame cover and the insert fitting with the square guide cover to supply air to multiple electrical cabinet air conditioners, making it easy to flexibly expand the cooling air supply system according to the distribution of electrical cabinet air conditioners in the factory area.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4 As shown, an active cooling circulation structure for a CNC machine tool control cabinet includes an air conditioning unit 1 and an air intake mechanism 3. The air intake mechanism 3 includes a square guide shroud 4, a tail tube 5, an extension duct 6, a connecting ring 7, a fan 8, symmetrical branch pipes 9, a connector 10, a back frame cover 11, and a conical filter screen 14. The square guide shroud 4 is fitted onto the outer air intake of the air conditioning unit 1, and the tail tube 5, which is integrated into the outer surface of the square guide shroud 4 and fitted into the extension duct 6, is integrally formed therewith. A fan 8 is installed at the outer opening of the extension conduit 6 away from the square guide cover 4, and a snap ring 7 is fitted inside the extension conduit 6 on one side of the fan 8. A conical filter screen 14 extending into the extension conduit 6 is welded into the ring hole of the snap ring 7. A symmetrical branch pipe 9 is integrally formed on the outer side of the extension conduit 6 between the fan 8 and the tail insert pipe 5. A head connector 10 is inserted into one set of pipe bodies of the symmetrical branch pipe 9. A back frame cover 11 is screwed onto the outer side of the remaining pipe body of the symmetrical branch pipe 9 away from the head connector 10.

[0019] The extension conduit 6 has a recessed stepped annular groove at the outer opening of the tube away from the tail insert 5, and a lap ring 7 is fitted inside the recessed stepped annular groove. By adopting the above technical solution, the clasp 7 can be fitted into the concave annular groove of the extension catheter 6.

[0020] The cone filter screen 14 has a core frame plate of inner frame ring 15 welded to the bottom of the screen via a riser, and a filter screen sheet 16 is welded between the inner frame body and the ring body of the inner frame ring 15. By adopting the above technical solution, the inner frame ring 15 can carry the filter screen 16 to form a two-stage filtration structure in the extension duct 6 behind the cone filter screen 14, thereby reducing the amount of dust and fumes entering the extension duct 6.

[0021] Among them, the extension guide 6 on the outer side of the lap ring 7 is symmetrically welded with an upper clamping plate 12 and a support plate 13, and the surface of the upper clamping plate 12 is provided with mounting holes for screwing the mounting bolts of the fan 8, and the housing of the fan 8 is pressed on the surface of the support plate 13. By adopting the above technical solution, the air outlet of the fan 8 can be blocked at the air inlet of the extension duct 6, and then the mounting plate of the fan 8 can be locked at the upper clamping plate 12 with bolts. At the same time, the housing of the fan 8 can be supported by the support plate 13.

[0022] Among them, the outer sides of the insert tube and the tail insert tube 5 of the insert connector 10 are symmetrically fitted with sealing rings, and the diameters of the insert tube and the tail insert tube 5 of the insert connector 10 are the same. The diameter of the other end of the insert connector 10 away from the insert tube is the same as the diameter of the extension guide tube 6. By adopting the above technical solution, the insert tube and tail insert tube 5 of the insert tube 10 can be sealed and inserted into the extension conduit 6 or the symmetrical branch pipe 9 with the help of the sealing ring. At the same time, the tail insert tube 5 of another set of square guide covers 4 can be inserted into the other end of the insert tube 10 away from the symmetrical branch pipe 9, so as to facilitate the supply of air to another set of electrical cabinet air conditioning bodies 1. After the back frame cover 11 at the symmetrical branch pipe 9 is rotated away, the remaining square guide covers 4 can be connected with the insert tube 10, so as to supply air to multiple sets of electrical cabinet air conditioning bodies 1.

[0023] The air conditioner body 1 of the electrical cabinet has a frame 2 welded to the shell near its own air inlet, and the frame 2 is embedded in the square guide cover 4. By adopting the above technical solution, the main body of the air conditioner cabinet 1 is sealed by a square guide cover 4 embedded in the frame 2 to prevent dust and smoke impurities from entering the contact surface between the square guide cover 4 and the main body of the air conditioner cabinet 1.

[0024] It should be noted that this utility model is an active cooling circulation structure for a CNC machine tool control cabinet. An air intake mechanism 3 is installed at the air conditioner body 1 of the control cabinet for active cooling circulation. The extension pipe 6 of the air intake mechanism 3 can be set according to the distance from the control cabinet to the outside of the factory area. Subsequently, multiple sets of symmetrical branch pipes 9 can be set according to the location of the machine tool control cabinet within the factory. A conical filter screen 14 and an inner frame ring 15 with filter screen pieces 16 are inserted into the pipe opening of the extension pipe 6 extending outside the factory area, allowing the overlapping ring 7 to be fitted into the concave annular groove of the extension pipe 6. Then, a fan 8 is installed at the upper clamping plate 12, pressed against the outside of the extension pipe 6. The housing of the fan 8 can be supported by a support plate 13. The lower part of the extension pipe 6 can be adjusted according to the support height under the guidance of welding technicians within the factory. The welding bracket is required to support the pipe below. The other end of the extended duct 6 away from the fan 8 can be connected by inserting the tail pipe 5 of the square guide cover 4. Then, this set of square guide covers 4 can be locked to the outside of the air cabinet air conditioner body 1 with bolts to cover the air inlet of the air cabinet air conditioner body 1 for air supply. At the symmetrical branch pipe 9, the back frame cover 11 can be unscrewed and the insert head pipe 10 can be inserted according to the distribution position of the other air cabinet air conditioner bodies 1 in the factory. The other end of the insert head pipe 10 away from the symmetrical branch pipe 9 can be connected by inserting the tail pipe 5 of another set of square guide covers 4 to facilitate air supply to another set of air cabinet air conditioner bodies 1. After the back frame cover 11 of several sets of symmetrical branch pipe 9 is unscrewed, the other square guide covers 4 can be connected by insert head pipe 10 to supply air to multiple sets of air cabinet air conditioner bodies 1. When the fan 8 introduces clean air from outside the factory area, it is filtered twice by the cone filter 14 and the filter screen 16, and then supplied to the square guide shroud 4 at the extension duct 6 and the symmetrical branch pipe 9. When the air conditioner body 1 encounters smoke and dust impurities at the control cabinet of the CNC machine tool, it is shielded by the square guide shroud 4, which makes it difficult for the air conditioner body 1 to suck in the smoke and dust generated by machining near the CNC machine tool, ensuring that the air conditioner body 1 can stably provide active cooling circulation for the control cabinet of the CNC machine tool. After removing the bolts of the square guide cover 4, the square guide cover 4 can be removed, which makes it easier to maintain the air conditioner body 1 of the electrical cabinet. After unscrewing the bolts at the upper clamping plate 12 and the fan 8, the fan 8 can be removed, and the connecting ring 7, the cone filter screen 14 and the inner frame ring 15 with the filter screen 16 can be taken out for cleaning and maintenance of the metal filter screen body.
