[0032] Among them, refer to Figure 2 and Figure 3 A first frame 140 is disposed horizontally in the electrical cabinet housing 100, and at least one filter layer 150 is detachably placed on the first frame 140. The filter layer 150 covers the frame holes of the first frame 140, and the filter layer 150 is used to filter dust in the air. The filter layer 150 divides the cavity 110 into an upper cavity 111 and a lower cavity 112, and the lower cavity 112 is used to install various electrical control components. Two air inlets 160 connected to the upper cavity 111 are disposed at the top of the electrical cabinet housing 100, and two fans 200 are symmetrically disposed at the top of the upper cavity 111, and the two fans 200 are respectively opposite to the two air inlets 160, and the two fans 200 are used to suck air from the two air inlets 160 and blow air into the upper cavity 111 after passing through the filter 161. The back plate 170 of the electric cabinet housing 100 is suspended, and is penetrated by a plurality of first air outlet holes 176 , and the left and right side plates of the electric cabinet housing 100 are penetrated by a plurality of second air outlet holes 180 , and the bottom plate of the electric cabinet housing 100 is provided with an air outlet 190 .

[0034] Compared with the prior art, the above one or more technical solutions in the machine tool electrical integrated distribution cabinet provided by the embodiment of the utility model have at least one of the following technical effects:

[0035] Reference Figure 2 and Figure 3When working, the two fans 200 operate to suck outside air into the upper cavity 111 from the two air inlets 160 and blow it into the lower cavity 112 after passing through the filter layer 150. Since the back plate 170 is provided with a plurality of first air outlet holes 176, the left and right sides of the electric cabinet shell 100 are provided with a plurality of second air outlet holes 180, and the bottom plate of the electric cabinet shell 100 is provided with an air outlet 190, the air blown into the lower cavity 112 quickly discharges the heat in the lower cavity 112 from the first air outlet holes 176, the second air outlet holes 180 and the air outlet 190, and the heat in the lower cavity 112 can be discharged from multiple directions at the same time, and the air flow effect is good, so that the air cooling and heat dissipation effect of the distribution cabinet is good.

[0036] The air outlet 190 can also be used as a threading port for cables, that is, the cables of the machine tool equipment pass through the air outlet 190 and are electrically connected to the electrical control components in the lower cavity 112, which facilitates wiring.

[0037] Reference Figure 2 At least one filter layer 150 is detachably placed on the first frame 140. The filter layer 150 filters dust in the passing air and blows it into the lower cavity 112, which greatly reduces the accumulation of dust in the electrical control components in the lower cavity 112 and ensures the normal operation of the electrical control components. In addition, the user can open the cabinet door 130 and easily remove the filter layer 150 from the upper cavity 111 to clean or replace the filter layer 150, which is easy to operate.

[0038] Further, refer to Figure 3 There is a cavity 101 between the back plate 170 and the back of the electric cabinet housing 100. The multiple first air outlet holes 176 of the back plate 170 are all facing the cavity 101. The left and right side plates and the bottom plate of the electric cabinet housing 100 are all provided with openings 102 connected to the cavity 101. The cavity 101 and the openings 102 are used for air circulation. Specifically, the cavity 101 is used for the heat in the lower cavity 112 to be discharged from the first air outlet holes 176 through the cavity 101 and the openings 102 to the outside. In addition, the cavity 101 is conducive to air circulation, which further improves the diffusion effect of the heat in the lower cavity 112.

[0039] Further, refer to Figure 3 The rear end wall of the lower cavity 112 is provided with a second frame 103, and the back plate 170 is fixedly arranged on the second frame 103. Specifically, the back plate 170 can be fixed on the second frame 103 by means of clamping, bonding, welding, or screwing.

[0040] Further, refer to Figure 2 The back plate 170 is symmetrically provided with vertical poles 171, and a plurality of horizontal poles 173 are horizontally provided between the two vertical poles 171. The horizontal poles 173 are used to install the electric control components, and the electric control components can be installed on the horizontal poles 173 by means of snap connection or screw connection.

[0041] Further, refer to Figure 2 The vertical rod 171 is provided with a plurality of screw holes 174 along its height direction, and the two ends of the cross bar 173 are provided with connection holes 175, and the connection holes 175 are screwed with the screw holes 174. By screwing the screws to the screw holes 174 at different heights, the installation position of the cross bar 173 can be adjusted, which is convenient for installing the electric control device (not shown in the figure).

[0042] Further, refer to Figure 2 The edge of the cabinet opening 120 is bent to form a reinforcing portion 121, and the reinforcing portion 121 can strengthen the strength of the edge of the cabinet opening 120, so that the cabinet opening 120 is not easily deformed and the structure is reliable.

[0043] Further, refer to Figure 2 A partition 106 is vertically disposed in the middle of the upper cavity 111, and the partition 106 separates the two fans 200. There is a gap between the bottom of the partition 106 and the first frame 140, and the filter layer 150 can be movably inserted into the gap and can be detachably placed on the first frame 140. The partition 106 separates the two fans 200, which can reduce the interference caused by the collision of the two fans 200 when they are running, and improve the blowing efficiency of the two fans 200.

[0044] Further, refer to Figure 2 and Figure 3 The left and right side panels of the electric cabinet housing 100 both extend outward with a plurality of mounting seats 104, and the mounting seats 104 are provided with mounting holes 105. The mounting holes 105 are combined with bolts to fix the electric cabinet housing 100 on the outer wall of the machine tool, so as to facilitate the installation of the electric cabinet housing 100.

[0045] Further, refer to Figure 1 and Figure 2 The left and right side panels of the electric cabinet housing 100 are both provided with a plurality of second air outlet holes 180 arranged along the height direction thereof. The arrangement of the plurality of second air outlet holes 180 is conducive to the heat in the upper cavity 111 being discharged from the plurality of second air outlet holes 180 driven by the fan 200 .

[0046] Further, refer to Figure 1 and Figure 2 The two air inlets 160 are both covered with a filter screen 161 , and the filter screen 161 is used to filter the dust entering the upper cavity 111 through the middle air inlet 160 .
