In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a coolant circulation system of a CNC cutting machine, including a shell 1 and an electric slide 4, a rectangular opening 2 for the workpiece and the cutter to enter is formed in the middle of the shell 1, a liquid storage tank 13 connected to the rectangular opening 2 is formed at the bottom of the shell 1, a water cavity is formed inside the top of the shell 1, a plurality of liquid outlet holes 12 connected to the water cavity are provided on the top surface of the rectangular opening 2, a filter bag 5 is provided in the opening of the liquid storage tank 13, a plurality of springs 7 for pressing the filter bag 5 into position are installed on the outer wall surface of the shell 1, the electric slide 4 is arranged on one side of the shell 1, a connecting rod 3 is installed between the moving platform of the electric slide and the shell 1, and a circulation mechanism is installed on one side of the shell 1.
[0022] In this embodiment, the circulation mechanism includes a circulation pipe 10 and a circulation pump 11. The circulation pipe 10 is installed on a side surface of the shell 1 away from the connecting rod 3. One end of the circulation pipe 10 is connected to the water cavity, and the other end is connected to the liquid storage tank 13. The circulation pipe 10 is installed in the middle of the circulation pipe 10.
[0023] In this embodiment, the open ends on both sides of the filter bag 5 are bent outward to form flanges 6, and the flanges 6 are placed on the open end surface of the liquid storage tank 13. One end of the spring piece 7 is bent inward to form an extrusion portion 8, and the extrusion portion 8 is set to contact the top surface of the flange 6. A pull block 9 is installed on the outer surface of the spring piece 7.
[0024] In this embodiment, the filter bag 5 is made of nylon material, which increases its firmness and service life and reduces the cost of replacement.
[0025] In this embodiment, the spring piece 7 is a metal spring piece, so that the spring piece has good elasticity, thereby being able to press the flange tightly.
[0026] In this embodiment, the housing 1 is made of stainless steel, which prevents rust and increases the service life.
[0027] The rectangular opening on the housing is arranged opposite to the clamping seat on the cutting machine tool, so that after one end of the workpiece is fixed on the clamping seat, the other end of the workpiece can be inserted into the rectangular opening, wherein the housing can move along the cutting of the workpiece. When it is needed, the electric push rod can be started, so that the moving platform of the electric push rod drives the connecting rod and the housing to move, so that the housing is always in the cutting position;
[0028] During the cutting process, the circulation pump can be started, and the circulation pump can extract the coolant in the liquid storage tank and inject it into the water cavity through the circulation pipe until it is discharged from the liquid outlet. The discharged coolant can directly flush the workpiece and the cutting head for cutting the workpiece, so as to cool them. Moreover, since the shell is directly sleeved on the outside of the tool, the internal circulation path of the coolant is shorter, and the amount of coolant is reduced. In addition, the shell can block part of the debris generated during cutting, and the blocked debris can be collected and processed by the filter bag.
[0029] When a large amount of debris is stored in the filter bag, the spring piece can be pulled outward by the pull block. After the extrusion part on the spring piece is separated from the flange, the filter bag can be directly taken out of the liquid storage tank upward, which is convenient for installation and disassembly.
