DETAILED DESCRIPTION

[0023] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0024] like Figure 1 、 2 As shown in Figure 3, a filtering device for coolant of a CNC milling machine comprises a filter box 101, a feed pipe 102 is provided at the left end of the filter box 101, a discharge pipe 103 is provided at the right end, a mounting frame 105 is provided inside the filter box 101, a filter screen 106 is detachably provided inside the mounting frame 105, a fixing component for fixing the filter screen 106 is provided at the upper right end of the mounting frame 105, a cover plate 107 is rotatably connected to the upper end of the filter box 101, a handle is fixedly provided at the upper end of the cover plate 107, and the cover plate 107 is provided to facilitate the staff to replace the filter screen 106, and a cleaning component for cleaning the filter screen 106 is provided at the left end of the mounting frame 105.

[0025] like Figure 1 、 2The cleaning component includes a slide 201 symmetrically arranged on the side wall of the filter box 101, and a slide rod 201 is slidably provided inside the slide, and a mounting bracket 202 is slidably provided between the two slide rods 201. The interior of the mounting bracket 202 is provided with a cleaning member. The cleaning member includes a brush plate 203 arranged inside the mounting bracket 202, and a brush bristle 204 is provided on the brush plate 203 to conflict with the filter screen 106. The upper end of the filter box 101 is provided with a driving member for driving the mounting bracket 202 to move. The driving member includes a telescopic push rod 205 arranged at the upper end of the filter box 101. The output end of the telescopic push rod 205 extends into the interior of the filter box 101 and is connected to the upper side wall of the mounting bracket 202. When the telescopic push rod 205 is started, its telescopic end drives the mounting bracket 202 to move up and down, and the mounting bracket 202 drives the brush plate 203 and the bristles 204 to clean the debris deposited on the filter screen 106 to avoid clogging at the mesh of the filter screen 106 and affecting the circulation effect of the coolant.

[0026] like Figure 1 、 2 As shown, a second through hole 206 is provided at the bottom of the filter box 101, and the second through hole 206 is located below the brush plate 203. A sedimentation box 104 is provided at the second through hole 206. By providing the sedimentation box 104, impurities such as metal debris cleaned from the filter screen 106 by the brush plate 203 can fall into the interior of the sedimentation box 104 through the second through hole 206 for collection.

[0027] like Figure 1 、 3 As shown in Figure 4, the fixing assembly includes a fixing box 301 arranged at the right end of the installation frame 105. A pin 302 is slidably provided inside the fixing box 301. The right end of the pin 302 is fixedly connected to a pull rod 303 slidably connected to the fixing box 301. A spring 304 is sleeved on the outer arc surface of one end of the pull rod 303 located inside the fixing box 301. One end of the spring 304 is connected to the right side wall of the pin 302, and the other end is connected to the right side wall of the fixing box 301. A pull plate 305 is provided at the right end of the pull rod 303, and a through hole 1 adapted to the pin 302 is provided on the right side wall of the installation frame 105, and a slot 306 adapted to the pin 302 is provided on the side wall of the filter 106. When the filter 106 needs to be replaced, the pull rod 303 is pulled toward the right end, and the pull rod 303 drives the pin 302 to compress the spring 304, so that it disengages from the inside of the slot 306 on the filter 106 so that the filter 106 can be disassembled.

[0028] During use, the coolant to be filtered is injected into the interior of the filter box 101 through the feed pipe 102, and the coolant flows through the filter screen 106 to filter the metal chips, dirt, impurities, etc. therein, to prevent these particles from circulating with the coolant to the key components of the machine tool, thereby reducing the risk of wear and blockage. The coolant after filtering is flown to the next processing step through the discharge pipe 103. After the filter screen 106 has been filtered for a period of time, some impurities may accumulate on the filter screen 106. At this time, the telescopic push rod 205 is started, so that its telescopic end drives the mounting frame 202 to move back and forth along the slide bar 201, and the mounting frame 202 drives the brush plate 203 and the bristles 204 to clean the impurities deposited on the filter screen 106. The cleaned impurities fall into the interior of the sedimentation box 104 through the second through hole 206, so as to clean the impurities and improve the filtering efficiency.

[0029] When the filter 106 needs to be replaced, open the cover 107 and pull the pull plate 305 to the right end. The pull plate 305 drives the pull rod 303 to move, and the pull rod 303 drives the pin 302 to compress the spring 304, so that it disengages from the inside of the slot 306 on the filter 106, so that the filter 106 can be removed from the installation frame 105. After the filter 106 is cleaned, the filter 106 is moved from the upper end of the installation frame 105 to the inside. At this time, lightly pull the pull rod 303 to make the side wall of the pin 302 conflict with the side wall of the filter 106, and continue to push the filter 106 to move toward the inside of the installation frame 105 until the pin 302 is inserted into the inside of the slot 306 under the action of the spring 304, thereby completing the disassembly and assembly of the filter 106.

[0030] According to another embodiment of the present invention, Figure 1 As shown, a sealing gasket 108 is provided on the side wall of the cover plate 107. The sealing gasket 108 ensures a tight fit between the cover plate 107 and the filter box 101, effectively preventing the coolant from leaking from the interface, and keeping the working environment clean and safe.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
