Chip liquid separation and recovery type chip removal device

Abstract

This utility model relates to the field of machine tool processing technology and discloses a chip removal device for separating and recovering cutting fluid. It includes a chip removal structure, an outer frame with a filter plate and a sponge pad installed on the surface of the inner plate. The cutting fluid flows along the filter plate. Because the diameter of the filter holes on the surface of the filter plate varies, the recovery box can filter chips of different sizes. After the first filtration, the cutting fluid flows into the interior of the sponge pad, where it is filtered again, blocking even finer chips and preventing them from re-entering the filtered cutting fluid. After the cutting fluid is filtered, the top plate can be pressed down, causing the roller to press down on the filter plate and sponge pad, squeezing the sponge pad containing the cutting fluid. At this time, the handle can be held to push the sliding plate left and right at the top of the lower bar, squeezing the sponge pad against the filter plate at the bottom, thus fully squeezing the sponge pad and avoiding waste of cutting fluid.

Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a chip discharge device with chip fluid separation and recovery. Background Technology

[0002] Chip removal devices are key auxiliary equipment for CNC machine tools. Their main function is to quickly remove chips generated during machining from the machining area, while simultaneously separating chips from cutting fluid to ensure machining efficiency and accuracy. This device is widely used in high-efficiency equipment such as CNC machine tools, machining centers, and grinding machines to prevent chip accumulation that could lead to decreased machining stability or safety hazards. Common types include flat chain type, scraper type, and spiral type, each suitable for different chip shapes and spatial conditions.

[0003] For example, the intelligent chip removal and oil recovery device disclosed in CN222608907U includes an oil recovery device housing located below the machine tool. A feed pipe is connected to the oil recovery device housing, and a machine tool recovery hopper is fixedly connected between the feed pipe and the machine tool. A filter support pipe is rotatably connected inside the oil recovery device housing. The traditional fixed filter screen is replaced with a cylindrical rotating filter screen, which is supported by the filter support pipe. Therefore, during oil filtration, the filtration area is large, and debris can be autonomously discharged through the rotation of the filter support pipe and the filter screen, as well as gravity. This results in low cleaning frequency, easy maintenance, and autonomous collection and discharge of debris, leading to fast oil filtration speed and meeting usage requirements.

[0004] The aforementioned patent proposes that oil is collected through a machine tool recovery hopper and then fed into the interior of a filter support tube through a feed pipe. Under the drive of the drive unit, the filter support tube rotates, which in turn drives the filter screen to rotate. The filter screen is used to separate oil from debris. However, during use, when the filter screen rotates too fast, the debris on the filter screen will be subjected to centrifugal force. In particular, smaller or lighter debris will be thrown outwards due to centrifugal force, or even forcibly pushed into the mesh of the filter screen, which will affect the filtration effect of the filter screen and thus interfere with the recovery of cutting fluid. Summary of the Invention

[0005] The purpose of this invention is to provide a chip discharge device for separating and recovering cutting fluid, so as to solve the problem of poor filtration effect of the filter screen mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chip discharge device for separating and recovering cutting fluid, comprising a chip discharge structure, wherein the chip discharge structure includes a recovery box and support legs installed on both sides of the bottom end of the recovery box, a liquid inlet hopper is installed at the top of the recovery box, and a detachable component is installed on one side of the bottom end of the recovery box;

[0007] The recycling bin includes an outer frame and an inner plate installed on the lower outer surface of the outer frame. Limiting strips are installed on the top of the outer frame and on both sides of the liquid inlet. A filter plate and a sponge pad are installed on the inner side of the outer frame and on the surface of the inner plate.

[0008] Preferably, a feeding frame is installed at the bottom of the built-in plate and on the side near the detachable component, an alignment hole is provided through the top of the limiting strip, and a cleaning component is provided at the top of the limiting strip and inside the recycling bin.

[0009] Preferably, the detachable component includes a fixing strip installed inside one end of the recycling bin, a rubber strip installed on the outer surface of the fixing strip, and a rear plate installed on the inner side of the recycling bin.

[0010] Preferably, threaded holes are provided on both sides of one end of the recycling bin, and bolts are threaded into the internal threads of the threaded holes.

[0011] Preferably, the cleaning component includes a top plate and a through groove formed in the middle of the top plate. Lower strips are installed on the surface of the top plate and on both sides of the through groove. Insert rods are installed on both sides of the bottom end of the top plate. Compression springs are installed on the bottom end of the top plate and on the outside of the insert rods.

[0012] Preferably, a slide plate is slidably installed inside the through groove and at the top of the lower strip. A handle is installed at the top of the slide plate, a limit ring is installed at the bottom of the slide plate, and a roller is movably installed on the inner side of the limit ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cutting fluid separation and recovery chip discharge device of this utility model allows the cutting fluid to flow along the filter plate. Since the diameter of the filter holes on the surface of the filter plate is different, the recovery box can filter chips of different sizes. After the first filtration, the cutting fluid flows into the interior of the sponge pad, where it is filtered again to block even smaller chips and prevent them from re-entering the filtered cutting fluid.

[0015] 2. The chip removal device for separating and recovering cutting fluid according to this utility model can press down the top plate after the cutting fluid has been filtered, so as to cause the roller to press down the filter plate and sponge pad, and squeeze the sponge pad containing cutting fluid. At this time, the handle can be held and the sliding plate can be pushed left and right at the top of the lower bar. The sponge pad squeezes the filter plate at the bottom, and the sponge pad is fully squeezed to avoid wasting cutting fluid. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 and Figure 2 A chip removal device for separating and recovering cutting fluid includes a chip removal structure 1. The chip removal structure 1 includes a recovery box 11 and support legs 12 installed on both sides of the bottom end of the recovery box 11. A liquid inlet hopper 13 is installed at the top of the recovery box 11, and a detachable component 14 is installed on one side of the bottom end of the recovery box 11.

[0023] The recycling bin 11 includes an outer frame 111 and an inner plate 112 installed on the lower outer surface of the outer frame 111. Limiting strips 115 are installed on the top of the outer frame 111 and on both sides of the liquid inlet 13. A filter plate 113 and a sponge pad 114 are installed on the inner side of the outer frame 111 and on the surface of the inner plate 112.

[0024] A feed frame 118 is installed at the bottom of the built-in plate 112 and on the side near the detachable component 14. An alignment hole 116 is provided through the top of the limiting strip 115. A cleaning component 15 is provided at the top of the limiting strip 115 and inside the recycling box 11. The feed frame 118 facilitates the collection of filtered cutting fluid.

[0025] In this embodiment: the inlet hopper 13 collects the cutting fluid flowing down from the machine tool. Since the outer frame 111 is inclined, the cutting fluid entering the outer frame 111 will flow along the filter plate 113. Since the diameter of the filter holes on the surface of the filter plate 113 is different, the collection box 11 can filter debris of different sizes. After the first filtration, the cutting fluid flows into the interior of the sponge pad 114, where it is filtered again to block even smaller debris and prevent it from re-entering the filtered cutting fluid. After the second filtration, the cutting fluid flows downward along the inner plate 112 at the bottom. The cutting fluid flows into the interior of the feed frame 118 through the opening of the inner plate 112 for centralized collection.

[0026] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The detachable component 14 includes a fixing strip 141 installed inside one end of the recycling bin 11, a rubber strip 142 installed on the outer surface of the fixing strip 141, and a rear plate 143 installed on the inner side of the recycling bin 11. The rubber strip 142 seals the space between the fixing strip 141 and the rear plate 143.

[0027] The recycling bin 11 has threaded holes 117 on both sides of one end. Bolts 119 are threaded inside the threaded holes 117. The bolts 119 are threaded into the rear plate 143, rubber strip 142 and fixing strip 141 to fix the position of the rear plate 143.

[0028] The cleaning component 15 includes a top plate 151 and a through groove 152 that extends through the middle of the top plate 151. Lower strips 153 are installed on the surface of the top plate 151 and on both sides of the through groove 152. Insert rods 157 are installed on both sides of the bottom end of the top plate 151. Compression springs 156 are installed on the bottom end of the top plate 151 and on the outside of the insert rods 157. The insert rods 157 are adapted to the alignment holes 116. The inner diameter of the compression springs 156 is larger than the diameter of the alignment holes 116.

[0029] A slide plate 154 is slidably installed inside the sliding groove 152 and at the top of the lower bar 153. A handle 155 is installed at the top of the slide plate 154. A limiting ring rod 159 is installed at the bottom of the slide plate 154. A roller 158 is movably installed on the inner side of the limiting ring rod 159. The outer surface of the roller 158 contacts the top of the filter plate 113 to facilitate the squeezing and drainage of the sponge pad 114.

[0030] In this embodiment: After the cutting fluid is filtered, the top plate 151 can be pressed down to cause the insertion rod 157 to pass through the alignment hole 116. The compression spring 156 contracts at the top of the limiting strip 115, causing the roller 158 to press down the filter plate 113 and the sponge pad 114, squeezing the sponge pad 114 containing the cutting fluid. At this time, the handle 155 can be held to push the slide plate 154 to move left and right at the top of the lower strip 153. The sponge pad 114 squeezes the filter plate 113 at the bottom, squeezing the sponge pad 114 completely to avoid wasting cutting fluid. After the operation is completed, after turning the bolt 119, the rear plate 143 can be pulled out from the side of the outer frame 111, which makes it easy to clean the filter plate 113 and the sponge pad 114. After the filter plate 113 and the sponge pad 114 are pulled out, the inside of the recycling box 11 is cleaned to prevent debris from remaining inside the recycling box 11.
