Description

Technical Field

[0001] The utility model relates to the technical field of coolants, and in particular to a multi-coolant supply device. Background Art

[0002] In traditional mechanical processing, emulsion has good cooling effect and is suitable for rough processing. However, if emulsion is used in fine processing, the lubrication effect is poor, which will reduce the surface roughness and processing accuracy of parts. Since emulsion has good cooling effect, but it is difficult to ensure processing accuracy, it is suitable for rough processing of products. If cutting oil is used for rough processing, the processing volume is large and the cooling effect is poor, it will cause environmental pollution, and it will cause the tool temperature to rise and reduce the tool life. Since the fine processing allowance is small and the cutting oil has good lubrication, the surface roughness of the workpiece and the size of the parts will increase during fine processing, so cutting oil is generally used for fine processing of parts. Therefore, the defect of the prior art is that it is difficult for a single cutting fluid to quickly match different processing requirements.

[0003] After searching, the announcement number CN213592398U discloses a multi-coolant supply device, including a shell, a first coolant delivery pump, a second coolant delivery pump, a third coolant delivery pump and an oil-water separator.

The multi-coolant supply device can solve the technical problem that the cutting fluid of the prior art processing equipment is difficult to quickly match different processing requirements.

[0004] However, the above-mentioned multi-coolant supply device still has the following problems: the above-mentioned multi-coolant supply device divides the shell into a cutting oil chamber, an emulsion chamber and a mixing chamber through two partitions, and the installation position of the partition is relatively fixed, so that the capacity of the cutting oil chamber and the emulsion chamber is constant, and in actual use, the workload of fine machining and rough machining may be different, which makes the amount of cutting oil and emulsion required for fine machining and rough machining different, and the above-mentioned multi-coolant supply device cannot specifically solve this problem.
