Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and in particular relates to a cooling liquid filtering structure for numerical control machine tools. Background Art

[0002] CNC machining is an effective way to solve problems such as a wide variety of parts, small batches, complex shapes, and high precision, and to achieve efficient and automated processing. During the CNC machining process, coolant is usually used to cool the related tools required for CNC machining.

[0003] After searching Chinese patents (publication number: CN219234731U), a coolant filtering mechanism for CNC machine tools is disclosed. The coolant is often accompanied by a large amount of debris generated during the processing after cooling the tool. The chips are usually directly mixed together and fall into the waste box, making it difficult to separate the coolant and the chips, which brings many difficulties to subsequent processing. However, when cleaning the chips, the device needs to drain all the water, and the cleaning cycle is too short, affecting the processing efficiency. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the present invention in conjunction with the specific implementation methods and with reference to the attached drawings. Figure 1-3 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] The utility model provides a cooling liquid filtering structure for a numerically controlled machine tool, comprising a filter pool 9, wherein a filter assembly is provided in the filter pool 9 in a liftable manner, wherein a filter cloth 7 is provided on the filter assembly in a detachable manner, wherein the filter assembly comprises a support frame 14 and a filter screen 22 arranged on the support frame 14, wherein the support frame 14 comprises a support frame 20, wherein a placement groove 23 is provided on the inner side of the support frame 20, wherein the filter cloth 7 is arranged in the placement groove 23, wherein a magnetic block 24 is provided at the upper end of the filter cloth 7, and wherein the material of the support frame 24 is iron. When the filter assembly is used for a long time, a large amount of waste debris is accumulated on the filter cloth 7, at which time the magnetic block 24 is removed, and the filter cloth 7 is removed from the support frame 20, and the filtered waste debris can be directly taken out, which is convenient and quick, and then a new filter cloth 7 is installed in the placement groove 23 on the support frame 20, and the magnetic block 24 is placed on the filter cloth 7, and the filter cloth 7 is fixed by magnetic attraction.

[0021] The filter assembly can be raised to the upper end of the filter pool 9. A lifting cylinder 13 is provided at the bottom center of the support frame 14. A lifting screw 12 is screwed into the lifting cylinder 13. The lifting screw 12 is connected to the lifting motor 11 at the bottom of the filter pool. A lifting track groove 16 is provided on the filter pool 9. A track block 15 corresponding to the lifting track groove 16 is provided on the support frame 14. When there is too much filter residue on the filter cloth 7, the lifting motor 11 rotates to drive the lifting cylinder 13 to move upward through the lifting screw 12, so that the filter assembly is raised to the upper end of the coolant level, which is convenient for replacing the filter cloth 7. After the replacement is completed, the lifting motor 11 rotates in the opposite direction to drive the filter assembly downward to continue the filtering work.

[0022] A water level detector 8 is provided at the upper end of the filter pool 9, and the water level detector 8 is embedded in the pool wall of the filter pool 9, and does not affect the lifting and lowering of the filter assembly. When the water level detector 8 detects an alarm, it indicates that the filtering efficiency of the filter assembly is reduced, and the filter cloth 7 needs to be replaced in time to prevent the coolant from overflowing. The automation is strong and does not require continuous attention from workers.

[0023] The filter pool 9 is provided with an inlet pipe 4 at the top, and a diverter is provided at the outlet of the inlet pipe 4. The diverter includes a conical diverter plate 17 and a connector 5 connected to the inlet pipe. The connector 5 is connected to the diverter plate 17 through a connecting rod 6. The coolant in the inlet pipe 4 falls on the diverter plate 17 and then falls on the filter assembly, which reduces the impact of the coolant on the filter assembly and increases the service life of the filter assembly. The diverter plate 17 is conical to avoid the accumulation of waste chips and leave no dead corners for filtering.

[0024] The water inlet pipe 4 is connected to the coolant pipe 19 through a universal telescopic tube 18. The setting of the universal telescopic tube 8 can facilitate the movement of the water inlet pipe 4. A lifter is provided on the water inlet pipe 4, and a water outlet pipe 10 is provided at the bottom of the filter tank 9. The lifter includes a water inlet pipe seat 3 fixed on the water inlet pipe 4, a suspension shaft 2 is provided on the water inlet pipe seat 3, a suspension rope 25 is provided on the suspension shaft 2, and the suspension rope 25 is connected to the reel 1. The height of the water inlet pipe head is determined by controlling the length of the suspension rope by the reel. During filtering, the water inlet pipe head is located directly above the filter tank to avoid the coolant flowing out and causing waste of coolant. When the filter cloth is replaced, the water inlet pipe rises, which is convenient for the operation of the filter assembly.

[0025] The utility model can facilitate the replacement of filter cloth by installing the filter component in a liftable manner on the filter pool without stopping the machine for waiting. At the same time, the filter cloth can be replaced quickly and conveniently. The diverter on the water inlet pipe can buffer the impact force of the coolant on the filter component and extend the service life of the filter component.
