Specifically, the hood (216) is disposed on one surface of the gear case (213), wraps the pulley (30) and the scraper (60), is open only at the lower portion through which the belt (50) passes, and is box-shaped. The protective cover (216) can prevent safety accidents in the operation process. The accidents that the fingers of the user are clamped between the belt (50) and the scraper (60) can be prevented. The second body (217) is disposed below the first body (211), and has a rectangular box body in which a space into which the lower body can be inserted is formed. The second body (217) is disposed below the first body (211) and has a rectangular shape in which a space into which the lower body can be inserted is formed. In the second body (217), the first step is a lever (218) connected by a hinge. When the first gear of the lever (218) is connected to the second main body (217) in a hinge mode, the other gears form a hanging buckle (2181) through the elastic force support of a spring (2182), and the hanging buckle can be hung on one of a plurality of connecting grooves (2221) formed on the lower main body (22). The lever (218) is fixed to the second body (217) by a latch hinge method, and is formed in a lever shape in such a manner that one side is pressed and the other side slides upward. In order to adjust the position of the pump (70), after the upper main body (21) is moved up and down, if the height of the upper main body (21) is determined, the hanging buckle (2181) of the lever (218) is hung on one of the connecting grooves (2221), so that the height of the upper main body (21) can be fixed. When the lower body (22) is provided with a bracket (221) at the lower part, the bracket (221) is provided with an embedding part (222). The embedded part (222) is an embedded part in the second body (217), and a plurality of connecting grooves (2221) are arranged on the side surface. The connecting groove (2221) is divided into a plurality of vertical directions, and the lever (218) arranged on the upper main body (21) can adjust the water immersion height of the pump (70). That is, the hook 2181 of the lever 218 is inserted into any one of the connection grooves 2221 to be combined therewith, and determines the height of the upper body 21. The pulley (30) is connected to a drive shaft (2121) of a motor (212) and a first transmission means (214), rotates with the drive shaft (212), and has an outer peripheral surface around which a belt (50) is wound. The drive shaft (2121) rotates the belt (50), and the belt (50) rotates together with the pulley (30). The roller 40 is mounted on the lower body 22, and guides a circulation path of the belt 50 while rotating together with the pulley 30 by winding the belt 50 around the pulley 30 according to the rotation of the pulley 30. The roller 40 is arranged as a lower side of the pulley 30 at a position opposed to the pulley 30 and is immersed in the cutting fluid tank 90. The belt (50) is wound around the pulley (30 years old) and the roller (40), at least a part of the belt is immersed in the cutting fluid S) in the cutting fluid tank (90), and the surface of the belt (50) is oiled.

Specifically, oil forming a coating on the surface of the cutting fluid adheres to the surface of the belt (50) due to the difference in specific gravity. Such a belt (50) may be made of an oil-absorbent material, depending on the oil characteristics. The scraper (60) is fixed to a gear case (213) of the upper body (21), and the first stage is configured to contact the surface of the belt (50) and scrape oil. The other gears are inclined downwards from the first gear, so that oil stained on the surface of the belt (50) can flow downwards by the self weight. The scraper (60) is fixedly arranged on one surface of the gear box (213), and the lower end of the scraper is provided with an oil guide rail (61). The pump (70) circulates the cutting fluid in the cutting fluid tank (90) to attract the belt (50) with oil on the surface of the cutting fluid. The pump (70) is configured to have a flow rate of the cutting fluid flowing into the pump body (71) faster than a flow rate of the cutting fluid discharged from the pump (70), and includes a pump body (71) and an impeller (72). The pump body (71) is provided with an impeller (72) inside, a water inlet (711) for the inflow of cutting fluid, and a water outlet (712) for the discharge of cutting fluid. The size of the water inlet (711) is smaller than the size of the water outlet (712), so that the flow rate of water near the water inlet (711) is faster than the flow rate of water under the water around the water outlet (712). A water inlet (711) is arranged at the upper side of the pump body (71), a water outlet (712) is arranged at the lower side of the pump body (71), and the cutting oil flowing in through the upper side of the pump body (71) is induced to be discharged through the water outlet by the impeller (72). The impeller (72) is arranged inside the pump body (71) as the lower side of the belt (50 years old), rotated by the driving force of the motor (212), and immersed inside the cutting fluid. The impeller (72) is directly connected to the bevel gear and the connecting rod, and the driving force of the motor (212) is transmitted through the gear, and if the driving shaft (2121) of the motor (212) rotates, the driving shaft is interlocked, and the impeller (72) also rotates. The cutting fluid in the cutting fluid tank is circulated as the impeller (72) inside the pump body (71) rotates. Specifically, the impeller (72) is designed to collect the cutting fluid around the belt (50) to form a fluid flow. The control unit (80) controls the motor (212). The control unit (80) allows a predetermined power supply to be approved by the motor (212), and enables the motor (212) to be opened and closed. The control unit (80) is connected to a timer (83) and causes the motor (212) to operate only for a predetermined time. In addition, the control part (80) is connected with the identification part (81), so that the operation state of the motor (212) can be displayed outwards through the picture. The control part (80) is arranged at the lower end of the main body (20) and is connected with a temperature sensing sensor (82) immersed in the cutting fluid, and the temperature of the cutting fluid sensed by the temperature sensing sensor (82) can be visually displayed through the mark part (81). The operator who knows the temperature of the cutting fluid can confirm the degree of deterioration of the cutting fluid. The temperature of the cutting fluid can be managed by workers, and finally certain processing quality is ensured. That is, when the temperature of the cutting fluid is too high, the worker can know that the temperature of the cutting fluid is lowered to an appropriate level by using an appropriate cooling device. The pump-type cutting fluid circulation and oil separation device (10) of the utility model has the following functions and effects that firstly, the pump-type cutting fluid circulation and oil separation device (10) is arranged in the cutting fluid groove (90). Then, the vertical position of the upper body (21) is adjusted in the cutting fluid of the cutting fluid pump (70), and the water immersion height of the pump (70) is adjusted. The rotating motor (212) drives the shaft (212) to rotate, and at the same time, the rotating force of the motor (212) is transmitted to the pulley (30) through the first transmission means (214), so that the belt (50) rotates. At the same time, the rotational force of the motor (212) is transmitted to the impeller (72) of the pump (70) via the bevel gear of the second transmission means (215), and the impeller (72) is rotated. When the impeller 72 rotates, the cutting fluid circulates, and specifically, as shown in fig. 9, the cutting fluid flows in through the impeller 72 via the water inlet 711 of the pump body 71, and the cutting fluid flows out of the water outlet 721. The cutting fluid flowing out from the water outlet (721) of the pump body (71) moves along the bottom surface of the cutting fluid tank (90), then rises again along the side surface of the cutting fluid tank (90), and then circulates again to the water inlet (711) of the pump body (71). In the utility model, the impeller (72) and the belt (50) can be started simultaneously by using one motor (212), and the circulation of oil and cutting fluid can be removed by a simple structure. The bevel gear for transmitting power to the pump (70) is mounted above the main body (20) instead of inside the cutting fluid. Because the cutting fluid only immerses the impeller (72). The bevel gear cutting machine has the advantage that foreign matters existing in cutting fluid cannot be clamped in the gap of the bevel gear. That is, there is no fear that foreign materials get stuck to the gear, so that it can operate for a long time without trouble. Fig. 10 schematically illustrates a process of removing grease, in which oil (O) of a coating of a cutting fluid (S) circulated by an impeller (72) is attached to a belt (50), and the oil on the surface of the belt (50) is removed from the surface of the belt (50) by a scraper (60) as the belt (50) moves endlessly. Then, the oil (O) flowing downward by gravity with the scraper (60) is collected in an oil receiving box (91) provided around the cutting fluid tank (90) as an oil guide rail (61) provided on the gear box (213) is lowered. The oil guide rail (61) can be adjusted in angle, so that the oil guide rail can be placed in recovery boxes at various positions as required to collect oil. In this case, the oil receiving box (91) is used for oil extraction and disposal, and an arbitrarily selected ordinary waste water tank can be used. Further, the water inlet (711) of the pump main body (71) is smaller than the water outlet (712), and therefore the flow velocity is high near the water surface. According to Bernoulli's principle, the lower end of the low-pressure fluid flowing cutting fluid box (90) which generates rapid flow velocity near the water surface can generate high-pressure fluid flow, and oil on the water surface can be collected rapidly and effectively. In this case, the cutting fluid is a water-soluble cutting fluid used for general machining, and the oil is a gear oil/lubricating oil type for general machines, and a water-insoluble oil is used. The pump type cutting fluid circulation and oil separation device according to the present invention is not limited to the above embodiment, and may be modified in such a manner that the driving force of the motor is directly connected to the pulley, and the power is transmitted when the angle of the pump is changed from the bevel gear to 90 degrees. That is, as shown in fig. 12 and 13, when the motor (212) is vertically erected, the pump (70) may be directly connected, and the pulley (30) may transmit power in a 90-degree angle change state by means of the bevel gear (31). The driving force generated by the single motor (212) can be directly transmitted to the pump (70), and the pulley (30) can change the power transmission angle to transmit the driving force. The above embodiment describes the pump-type cutting fluid circulation and oil separation device according to the present invention, but the present invention is not limited thereto, and various modifications can be made.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
