Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1 Combined with Figure 2 , the embodiments of the present utility model include:

[0016] A numerical control machine tool electrical cabinet, including a cabinet door 1, a cabinet body 2, a drive installation component, a heat dissipation component and an electrical component.

[0017] Among them, the cabinet door 1 is fixed at the opening on the front side of the cabinet body 2 through a rotating snap ring 3, which is convenient for opening and closing. A rubber ring is provided on the cabinet door 1 to keep the electrical cabinet in a closed state.

[0018] A switch buckle 4 is arranged on the movable side of the cabinet door 1 for opening and closing the cabinet door 1.

[0019] A plurality of Ethernet ports 5 are arranged at the bottom of the fixed side of the cabinet door 1. The Ethernet receiving device is installed in the reserved hole of the Ethernet port 5, which is customized for the interaction between the outside and the machine tool. The position is moderate, close to the operator, convenient for maintenance, and a multi-functional module is built.

[0020] A serrated cable fixing row 6 is arranged at the front side of the top inside the cabinet body 2. With a serrated design, it can realize wire inlet at any angle and fix it on the wire groove, which can reduce the heat generated by the wire swing friction.

[0021] A plurality of wire outlet holes 7 are arranged on one side of the top of the cabinet body 2, which are fixed grooves for power lines and signal lines, and a distance is reserved for the lines to pass through.

[0022] A longitudinally distributed fixed wire groove 8 is arranged on one side below the wire outlet hole 7 of the cabinet body 2 for centralized wire supply of the wire harness and leading it out through the wire outlet hole 7.

[0023] A plurality of multi-functional mounting holes 9 are arranged at the lower part of the opposite side of the fixed wire groove 8 of the cabinet body 2, and a plurality of cable fixing mounting holes 10 are arranged at the bottom of the cabinet body 2, realizing the characteristic of multi-functional connection of the electrical cabinet. The multi-functional mounting holes 9 reserve the mounting surface for heavy-duty power signals through punching. Each mounting surface has four screw holes to fix the external installation. Many mounting hole positions are designed to meet the subsequent function addition and the configuration is perfect.

[0024] The drive installation component includes a drive installation bin 11 and a drive module 12. The drive installation bin 11 is fixed to the other side of the inner top of the cabinet body 2 and is fixedly attached to the back and side portions. The drive installation bin 11 and the side portion of the cabinet body 2 are provided with an air outlet 13 and an air inlet 14 which are vertically distributed. The drive module 12 is correspondingly arranged in the drive installation bin 11. After the drive is fixed, the cable passes through the serrated cable fixing row 6 and extends to the wire outlet hole 7 to connect out of the electrical cabinet.

[0025] The heat dissipation component is correspondingly arranged on the cabinet door 1 and the air outlet 13, and includes a first heat dissipation fan 15, a heat insulation space plate 16 and a second heat dissipation fan 17.

[0026] The first heat dissipation fan 15 is fixed on the air outlet 13 to dissipate heat. The air inlet 14 is provided with a dust-proof and waterproof cotton to prevent dust and water droplets from entering. Under the action of atmospheric pressure, the high-temperature gas will gather in the upper layer. While the first heat dissipation fan 15 blows outwards, it forms a communication effect with the air inlet 14 to conduct ventilation at all times, achieving the effect of cooling the main heat generation area.

[0027] The heat insulation space plate 16 is embedded in the fixed side of the cabinet door 1. The second heat dissipation fan 17 is fixed at the lower part of the heat insulation space plate 16. In a closed environment, the heat diffuses slowly and accumulates around the heat generating components and wires. Through the combination of the second heat dissipation fan 17 and the heat insulation space plate 16, the wind force of the second heat dissipation fan 17 is compressed by the heat insulation space plate 16, so that the wind force gathers and blows out from the uppermost end of the heat insulation space plate 16. The upper air outlet and the air suction of the second heat dissipation fan 17 form an internal circulation, making the inside of the electrical cabinet form a circulation. The heat accumulated at the upper end is blown to the bottom and sucked into the heat insulation space plate 16. As the heat insulation space plate 16 absorbs heat and diffuses it into the external air, the temperature of the electrical cabinet is evenly distributed within a safe operating temperature.

[0028] The electrical component is fixed to the back inside the cabinet body 2 and is located below the drive installation component, and includes a wiring row 18, a grounding row 19, three groups of relay I / O boards 20, two groups of circuit breakers 21, a power supply 22 and a contactor 23.

[0029] Specifically, the terminal block 18, the grounding bar 19, the relay I / O board 20 and the relay I / O board 20, the circuit breaker 21 and the relay I / O board 20, the power supply 22, the circuit breaker 21 and the contactor 23 are arranged at intervals from top to bottom, and a wiring groove 24 is provided at any of the intervals. The circuit breaker 21 controls the entire circuit and strictly protects the line from tripping in time when overloaded to reduce the temperature rise. Each component is connected through the wiring groove 24, breaking the traditional wiring method of bundling with cable ties. Enough wiring grooves 24 are left for easy placement and troubleshooting. The wiring groove 24 is also covered with a cover plate to prevent the wires from being intertwined when connecting the wires and to keep the entire electrical cabinet clean and beautiful.

[0030] The wiring groove 24 uses a serrated shape with gaps to facilitate the connection and passage of wires and the heat dissipation of electrical wires. The heat diffuses into the air in the electrical cabinet through the tooth gaps, and it is convenient for the circulating air to suck away the temperature.

[0031] In summary, a numerical control machine tool electrical cabinet pointed out by the present utility model has complete functions, centralized modules and separate classifications. On the premise of realizing multi-functional and diversified control of the machine tool, it safely controls the machine tool and improves efficiency. The electrical cabinet is simple, beautiful, safe and reliable, greatly reducing the risk of short circuit and burnout caused by complex cable entanglement; in a closed dust-proof and waterproof environment, while reducing heat generation, a large amount of heat emitted from a fixed position can be evenly distributed through the action of the internal circulating air flow by the electrical cabinet fan, and the heat is dissipated into the surrounding air through the electrical cabinet itself, achieving the effect of reducing the temperature inside the cabinet while reducing costs, protecting the safety of components and cables, and also achieving the environmental protection effect of energy conservation and emission reduction.
