Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a machining oil self-supplementing device. Background Technique

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Processing equipment usually has an oil tank to store cutting fluid.

[0003] The oil tank set in the processing equipment usually has an oil pump to transport the cutting fluid in the oil tank into the processing equipment.

[0004] In view of the above related technologies, the inventor believes that in the prior art, people often have to check the oil tank to see if cutting fluid needs to be replenished, which is extremely inconvenient. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides a machining oil self-supplementing device, which solves the problems raised in the above background technique.

[0007] (2) Technical Solution

[0008] To achieve the above object, the utility model is realized through the following technical solutions: a machining oil self-supplementing device, including a box body, a float valve mechanism and an exhaust valve. An inlet is opened at the top of one side of the box body, and an outlet is opened at the bottom of the other side of the box body opposite to the inlet. A fixed block is fixedly installed in the box body near the outlet. A siphon tube is opened in the fixed block. An air-liquid tube is arranged at the top of the siphon tube.

[0029] The present utility model will be further elaborated in detail below with reference to the drawings and embodiments.

[0030] As Figures 1-4 shown: A machining oil self-supplementing device includes a box body 1. A liquid inlet 11 is provided on one side of the box body 1. The part of the liquid inlet 11 extending into the box body 1 is a right-angle pipe. Refer to Figure 1 , on the bottom of the other side of the box body 1 away from the liquid inlet 11, a liquid outlet 12 is opened. The liquid outlet 12 is connected to the machine tool liquid inlet device. Inside the box body 1 near the liquid outlet 12, a fixed block 15 is installed. A siphon tube 13 is provided inside the fixed block 15. The siphon tube 13 is arranged in an inverted U shape.

[0031] Since the siphon tube 13 is sealed, when the equipment stops being used, air bubbles are likely to enter at the liquid outlet end of the machine tool, thus affecting the flow of cutting fluid in the siphon tube 13. Therefore, a gas-liquid tube 14 is provided at the top of the inverted U-shaped siphon tube 13. The gas-liquid tube 14 extends outside the box body 1 and the outer end is bent upward at a right angle. An exhaust valve 3 is installed at the top for exhausting the gas in the siphon tube 13. Since the gas is lighter, it will enter the exhaust valve 3 at the end of the gas-liquid tube 14 through the siphon tube 13. When there is too much gas in the exhaust valve 3, the cutting fluid in the exhaust valve 3 will be pushed out, and the floating block 32 will lose the buoyancy and drop.

[0032] A fixed groove 322 is opened at the top of the floating block 32. A sealing rod 323 is installed in the fixed groove 322. An air outlet pipe 311 is installed on one side of the housing 31 of the exhaust valve 3. The top of the sealing rod 323 is a rubber cushion block for sealing the air outlet pipe 311 located inside the housing 31. A spring 33 is sleeved on the air outlet pipe 311 inside the housing 31 and the sealing rod 323.

[0033] When the floating block descends, the spring 33 bends, causing the sealing rod 323 to follow the floating block 32 and descend, thereby opening the air outlet pipe 311. Due to the pressure in the box body 1, the cutting fluid in the exhaust valve 3 rises to discharge gas. During the rising process of the cutting fluid, the floating block 32 floats upward and drives the sealing rod 323 to seal the air outlet pipe 311 again. The limit plate 324 provided at the top of the floating block 32 is used to limit the floating block 32 to prevent the cutting fluid from causing the floating block 32 to continue floating upward and contacting the top inside the housing 31, resulting in the sealing rod 323 opening again and causing the cutting fluid to overflow.

[0034] A slide bar 16 is installed below the liquid inlet 11 inside the box body 1. A floating valve mechanism 2 is sleeved and slid on the slide bar 16. The floating valve mechanism 2 includes a floating body 21 and a sealing block 22 installed on the top of the floating body 21 and cooperating with the liquid inlet 11.

[0035] When the liquid level in the box drops, the floating body 21 moves downward to open the liquid inlet 11 for replenishing liquid. The liquid falls into the box body 1 through the liquid inlet 11. The rising liquid level drives the floating body 21 to float, causing the sealing block 22 to block the liquid inlet 11, completing automatic liquid replenishment.

[0036] When the liquid level in the box body 1 is too low, the cutting fluid flows into the box body 1 through the liquid inlet 11, and the oil fluid enters the machine tool through the siphon tube 13. The air at the machine tool end flows backward into the siphon tube 13 and is discharged from the exhaust valve 3. The liquid inlet 11 should be higher than the exhaust valve 3 and the siphon tube 13, aiming to achieve the siphon effect so that no bubbles will appear when the machine tool uses the cutting fluid.

[0037] As described above, based on the embodiments as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the idea of this invention. The technical scope of this utility model is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
