Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid circulation, in particular to a cutting fluid circulation device which can avoid blockage. Background Art

[0002] Cutting fluid is a substance designed for use in metalworking and machining processes where it performs the dual role of lubricant and coolant.

[0003] The prior art does not have a structure for filtering out floating oil on the cutting fluid surface and filtering and circulating the cutting fluid when in use. As a result, when the prior art cutting fluid is in use, due to a large amount of protective oil or lubricating oil remaining on the surface of the workpiece, when the cutting fluid flushes the workpiece during processing, the oil can easily slide into the waste liquid barrel along with the cutting fluid, and needs to be separated by other equipment before it can be used, which is rather cumbersome. At the same time, when in use, the cutting fluid will carry a large amount of fine impurities with it and still needs to be collected and filtered by other equipment before it can be used. It cannot achieve self-filtration circulation and is inconvenient to use. Based on the deficiencies of the prior art, the utility model designs a cutting fluid circulation device that avoids blockage. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a cutting fluid circulation device which avoids clogging and has the advantages of filtering out floating oil on the surface of the cutting fluid and filtering and circulating the cutting fluid.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. A cutting fluid circulation device that avoids clogging. When the cutting fluid level is higher than the lowest point of the oil drain tank and there is floating oil on the surface, the float squeezes the floating oil due to its own density and floats on the cutting fluid surface. Since the top surface of the movable baffle is flush with the bottom surface of the float, after the float is flush with the cutting fluid surface, the float drives the through groove to rise and fall through the connecting rod to keep it flush with the cutting fluid surface. At this time, the floating oil slightly higher than the top surface of the movable baffle passes through the top of the movable baffle and flows into the interior of the oil storage tank for collection. The device is convenient for filtering out the floating oil on the surface of the cutting fluid.

[0016] 2. A cutting fluid circulation device that avoids clogging, wherein the liquid storage tank is placed under the lathe, and when the lathe is performing turning operations, the circulation pump is started to pump the turning fluid in the separation tank into the liquid outlet pipe for discharge to cool the lathe workpiece, and the sprayed turning fluid carries metal chips with it when falling and falls onto the separation plate for collection. Since filter holes are provided on the separation plate, the turning fluid that falls into the separation plate will pass through the filter holes and flow back into the separation tank to achieve circulation, while the metal chips will be intercepted by the filter holes. Finally, the separation plate can be taken out by holding the pull rod to clean up the chips. The device facilitates the recycling of cutting fluid. BRIEF DESCRIPTION OF THE DRAWINGS

The inner end of the connecting rod 306 is fixedly connected to the top surface of the movable baffle 304. The movable baffle 304 is slidably connected to the inside of the oil drain groove 302. The top surface of the movable baffle 304 is flush with the bottom surface of the float 307. The density of the float 307 is less than the density of the cutting fluid but greater than the density of the floating oil on the cutting surface.

[0026] By setting the float 307 and the connecting rod 306, the movable baffle 304 can be controlled in real time according to the cutting fluid level to keep it flush with the liquid surface. By setting the movable baffle 304, the cutting fluid in the separation tank 102 can be intercepted so that the floating oil on the cutting fluid surface above the movable baffle 304 can pass through from above and flow into the oil storage tank 103 for collection.

[0027] See also Figure 4 A filter hole 201 is formed through the separation plate 2, a fixed column 202 is fixedly connected to the bottom of the inner cavity of the separation tank 102, a support plate 203 is fixedly connected to the fixed column 202, a pull rod 204 is fixedly connected to the upper surface of the separation plate 2, a rotating hole 205 is formed on the top surface of the liquid storage tank 1, a limited rotating plate 206 is rotatably inserted inside the rotating hole 205, a side groove 207 is formed on one side of the separation plate 2, the separation plate 2 is arranged on the upper surface of the support plate 203, the limited rotating plate 206 is arranged on the top of the fixed column 202, and a connecting rod 306 is inserted inside the side groove 207.

[0028] The separation plate 2 is provided to collect the used cutting fluid and metal debris, the filter hole 201 is provided to filter and separate the metal debris contained in the cutting fluid, and the pull rod 204 is provided to quickly lift the separation plate 2 to clean the metal debris filtered out by the filter hole 201.

[0029] Working principle: when a cutting fluid circulation device that avoids clogging is used, in the initial state, first, the separation tank 102 and the oil storage tank 103 are opened inside the liquid storage tank 1, and the oil discharge valve 104 and the circulation pump 105 arranged outside the liquid storage tank 1 are communicated with the oil storage tank 103 and the separation tank 102 respectively, so as to circulate the cutting fluid and discharge the filtered oil. A filter hole 201 is opened on the separation plate 2 arranged in the separation tank 102, and the separation plate 2 is limited and supported by the fixed column 202 and the support plate 203, so as to filter the cutting fluid. At the same time, a partition plate 301 is arranged between the separation tank 102 and the oil storage tank 103, and a movable baffle 304 is raised and lowered in the oil discharge tank 302 that runs through the partition plate 301, and the movable baffle 304 is controlled by the connecting rod 306 and the float 307, so as to filter the oil according to the liquid level.

[0030] When it is necessary to filter out the floating oil on the surface of the cutting fluid, first when the cutting fluid level is higher than the lowest point of the oil drain groove 302 and there is floating oil on the surface, the float 307 squeezes the floating oil due to its own density and floats on the cutting fluid surface. Since the top surface of the movable baffle 304 is flush with the bottom surface of the float 307, after the float 307 is flush with the cutting fluid surface, the float 307 drives the through groove 305 to rise and fall through the connecting rod 306 to keep it flush with the cutting fluid surface. At this time, the floating oil slightly higher than the top surface of the movable baffle 304 passes through the top of the movable baffle 304 and flows into the interior of the oil storage tank 103 for collection. This device is convenient for filtering out the floating oil on the surface of the cutting fluid.

[0031] When the cutting fluid needs to be recycled, first place the liquid storage tank 1 under the lathe. When the lathe is performing turning operations, start the circulation pump 105 to pump the cutting fluid in the separation tank 102 into the liquid outlet pipe 106 for discharge to cool the lathe workpiece. When the sprayed cutting fluid falls, it carries metal chips with it and falls on the separation plate 2 for collection. Since the separation plate 2 is provided with a filter hole 201, the cutting fluid will pass through the filter hole 201 after falling into the separation plate 2 and flow back into the separation tank 102 to achieve circulation, while the metal chips will be intercepted by the filter hole 201. Finally, hold the pull rod 204 to take out the separation plate 2 to clean up the debris. This device facilitates the recycling of cutting fluid.
