Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a chip fluid circulation filtration device for machine tool processing. Background Technology

[0002] When a machine tool processes and cuts a workpiece, high temperatures are generated between the cutting tool and the workpiece, affecting the cutting process. Operators usually use cutting fluid to spray the workpiece to cool it down. After use, the cutting fluid will contain a lot of iron filings. Therefore, it is necessary to use a filter device to remove metal particles from the cutting fluid, thereby extending the service life of the cutting fluid, reducing tool wear, improving tool durability, and thus improving production efficiency.

[0003] Some cutting fluid filtration devices simply filter the cutting fluid and then reuse it. However, this method is inefficient, cannot guarantee the filtration effect of the cutting fluid, and the filter plate of the filtration device will accumulate a lot of impurities during long-term use, which can easily cause the filter screen to become clogged, thus affecting the filtration of cutting fluid. Moreover, the filtration mechanism is relatively troublesome to disassemble. Therefore, it does not meet the existing needs. In response, we propose a cutting fluid circulation filtration device for machine tool processing. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting fluid circulation filtration device for machine tool processing, in order to solve the problems mentioned in the background art. Some cutting fluid filtration devices often simply filter the cutting fluid and then reuse it. However, this method is inefficient and cannot guarantee the filtration effect of the cutting fluid. In addition, the filter plate of the filter device will accumulate a lot of impurities during long-term use, which can easily cause the filter screen to be blocked, thereby affecting the filtration of the cutting fluid. Furthermore, the filter mechanism is troublesome to disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machining fluid circulation filtration device for machine tools, comprising a filter box, an inlet at the top of the filter box, an outlet connected to the side of the filter box near the bottom via a valve, mounting grooves at the top and bottom of the front end of the filter box, a filter frame detachably mounted inside the upper and lower mounting grooves, sliding strips fixedly connected to both sides of the outer surface of the filter frame, and the filter frame slidably connected to the inside of the mounting groove via the sliding strips, and a filter screen fixedly connected to the inside of the filter frame near the bottom.

[0006] Preferably, symmetrical grooves are provided on both sides of the front end of the filter frame, and crossbars are fixedly connected inside the grooves on both sides. Sliding plates are slidably connected to the outer surfaces of the crossbars on both sides and inside the grooves, with one end of the sliding plate extending through to the outside of the groove.

[0007] Preferably, the ends of the sliding plates on both sides that are close to each other are fixedly connected to the inner wall of the groove with springs, and the springs are wound around the outer surface of the crossbar.

[0008] Preferably, a limiting plate is fixedly connected to the ends of the sliding plates on both sides that are far apart from each other. The end of the limiting plate that is far away from the sliding plate moves through the groove and extends to the outside of the filter frame.

[0009] Preferably, symmetrical limiting grooves are provided on both sides of the inner wall of the mounting groove near the outer end, and the limiting plate extends through to one end of the filter frame and is inserted into the corresponding limiting groove.

[0010] Preferably, the bottom of the filter box is fixedly provided with a downward inclined guide block, and the rear side of the liquid outlet is provided with a return pipe that is connected to the inside of the filter box. Both the return pipe and the liquid outlet are located at the lowest inclined end of the guide block.

[0011] Preferably, a support plate is fixedly provided on the outer surface of the filter box near the upper end, and a water pump is provided at the upper end of the support plate. One end of the return pipe is connected to one side of the water pump, and the side of the water pump away from the return pipe is connected to the interior of the filter box through a connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, after the cutting liquid is filtered by the upper and lower filter screens inside the filter box, it accumulates at the bottom of the filter box. Then, guided by the guide block, the water pump is started. The water pump draws the filtered cutting liquid through the return pipe and sends it back to the upper end of the filter box through the connecting pipe. After another round of filtration, the filtration effect is improved.

[0014] 2. This utility model allows the sliding plates on both sides of the outer surface to be pinched, causing them to move along the crossbar towards each other and compress the spring. This, in turn, causes the limiting plate to disengage from the limiting groove and move into the interior of the groove. This releases the connection limit between the filter frame and the mounting groove, and allows the filter frame to be disassembled from the interior of the mounting groove for cleaning, thus preventing the filter screen from becoming clogged and affecting the filtration of cutting fluid.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1 As shown, one embodiment of this utility model is provided: a cutting fluid circulation filtration device for machine tool processing, including a filter box 1, an inlet 2 at the top of the filter box 1, an outlet 3 connected to the side of the filter box 1 near the bottom via a valve, mounting grooves 101 at the top and bottom of the front end of the filter box 1, and a filter frame 4 detachably installed inside the upper and lower mounting grooves 101, with sliding strips 5 fixedly connected to both sides of the outer surface of the filter frame 4, and the filter frame 4 slidably connected to the inside of the mounting groove 101 via the sliding strips 5, and a filter screen 6 fixedly connected to the inside of the filter frame 4 near the bottom.

[0022] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, a downward-sloping guide block 11 is fixedly provided at the bottom of the filter box 1. A return pipe 14 is provided on the rear side of the outlet 3 and is connected to the interior of the filter box 1. One end of the return pipe 14 and one end of the outlet 3 are both located at the lowest inclined end of the guide block 11. A support plate 12 is fixedly provided on the outer surface of the filter box 1 near the upper end. A water pump 13 is provided at the upper end of the support plate 12. One end of the return pipe 14 is connected to one side of the water pump 13. The side of the water pump 13 away from the return pipe 14 is connected to the interior of the filter box 1 through a connecting pipe 15.

[0023] In this embodiment, guided by the guide block 11, the water pump 13 is started. The water pump 13 pumps the filtered cutting liquid through the return pipe and sends it back into the upper end of the filter box 1 through the connecting pipe 15. After another round of filtration, the filtration effect is improved.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4As shown, symmetrical grooves 401 are provided on both sides of the front end of the filter frame 4. A crossbar 7 is fixedly connected inside the grooves 401 on both sides. A sliding plate 8 is slidably connected to the outer surface of the crossbar 7 and inside the groove 401. One end of the sliding plate 8 extends through to the outside of the groove 401. A spring 9 is fixedly connected between the ends of the sliding plates 8 that are close to each other and the inner wall of the groove 401. The spring 9 is wrapped around the outer surface of the crossbar 7. A limiting plate 10 is fixedly connected to the ends of the sliding plates 8 that are far from each other. The end of the limiting plate 10 that is far from the sliding plate 8 moves through the groove 401 and extends to the outside of the filter frame 4. Symmetrical limiting grooves 102 are provided on both sides of the inner wall of the mounting groove 101 near the outer end. The end of the limiting plate 10 that extends through to the outside of the filter frame 4 is inserted into the corresponding limiting groove 102.

[0025] In this embodiment, by pinching the sliding plates 8 on both sides of the outer surface, the sliding plates 8 on both sides move along the crossbar 7 toward the side that is closer to each other, and compress the spring 9, thereby causing the limiting plate 10 to disengage from the limiting groove 102 and move into the interior of the groove 401, thereby releasing the connection limit between the filter frame 4 and the mounting groove 101, and the filter frame 4 can be disassembled from the interior of the mounting groove 101 to clean the filter screen 6.

[0026] When using the machining fluid circulation filtration device, the used cutting fluid is introduced into the filter box 1 through the inlet 2. After being filtered by the filter screens 6 inside the filter box 1, the cutting fluid accumulates at the bottom of the filter box 1. Then, guided by the guide block 11, the water pump 13 is started. The water pump 13 pumps the filtered cutting fluid through the return pipe and sends it back into the upper part of the filter box 1 through the connecting pipe 15. After another round of filtration, the filtration effect is improved.

[0027] After prolonged use, the filter screen 6 inside the filter frame 4 can be squeezed by pinching the sliding plates 8 on both sides of the outer surface. This causes the sliding plates 8 on both sides to move towards each other along the crossbar 7, compressing the spring 9 and causing the limiting plate 10 to disengage from the limiting groove 102 and move into the interior of the groove 401. This releases the connection limit between the filter frame 4 and the mounting groove 101, allowing the filter frame 4 to be disassembled from the interior of the mounting groove 101 for cleaning of the filter screen 6 to prevent clogging and ensure proper filtration of the cutting fluid.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
