Description

Technical Field

[0001] The present invention relates to the technical field of chip removal of machine tools, and more particularly to a water flushing chip removal system. Background Art

[0002] A chip conveyor is a device used to discharge and collect waste materials. In equipment such as numerical control machine tools and machining centers, a chip conveyor is used to form a chip removal system to separate and filter waste materials and coolant.

In this chip removal device, the chain plate type chip conveyor and the water tank are arranged in parallel. When it is necessary to move the chain plate type chip conveyor out for cleaning, only a distance slightly larger than the width of the water tank needs to be reserved beside the machine tool to achieve this. In a plant with limited space, the utilization rate of the plant is effectively improved, thereby improving production efficiency; and the chain plate type chip conveyor and the water tank are arranged in parallel, which reduces the production process of producing the above chip removal device, reduces the overall weight, reduces the processing materials used, and reduces the production cost; the cutting fluid and chips received by the chain plate type chip conveyor can flow into the water tank faster and are not easily precipitated in the chain plate type chip conveyor, extending the cleaning cycle of the chain plate type chip conveyor.

[0004] In the prior art including the above patent, most of the chip conveyors cooperating with the coolant water tank are chain plate type chip conveyors. During the process of machining in the airport, long spiral waste materials and fine chip waste materials will be cut out. The fine chip waste materials are likely to fall into the coolant tank and accumulate during transportation, and it is difficult for the chain plate type chip conveyor to scrape off the fine chips, which is easy to accumulate chips and breed bacteria.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] like Figure 1-12 As shown, a water-flushing chip removal system includes a chip conveyor frame 1, and the chip conveyor frame 1 includes:

[0037] A frame shell 11, on which an accumulation channel 110 and a compression arc channel 12 are arranged;

[0038] The chip removal mechanism 2 comprises a chain plate 21 sleeved on the frame housing 11, and a plurality of retractable scrapers 22 are arranged on the chain plate 21 in a linear array;

[0039] The retractable scraper 22 moves along with the chain plate 21 to scrape the debris along the accumulation channel 110 and slides out of the accumulation channel 110 along the compression arc path 12 .

[0040] Specifically, an inclined discharge part 10 and a material receiving port 111 that communicate with each other are provided on the frame housing 11. The inclined discharge part 10 communicates with the accumulation channel 110, and the material receiving port 111 communicates with the compression arc channel 12. The material receiving port 111, the compression arc channel 12, the accumulation channel 110, and the inclined discharge part 10 form a cycle of the chain plate 21. The material receiving port 111 is docked with the material receiving hopper of a five-axis machine tool or a machining center to collect waste materials and coolant. A symmetrical predetermined distance (the predetermined distance is 20 mm to 35 mm) is reserved between the chain plate 21 and the frame housing 11. When the coolant (also called cutting fluid) flows along the material receiving hopper into the chain plate 21 through the material receiving port 111, it will flow into the accumulation channel 110 along the predetermined distance and flow along the inner wall of the accumulation channel 110, flushing the fine debris along with the coolant to the center of the accumulation channel 110 for convenient scraping by the telescopic scraper 22. An electric motor is provided on the inclined discharge part 10, and the output end of the electric motor is arranged inside the chain plate 21 through a connecting shaft to drive the chain plate 21 to rotate. During use, the chain plate 21 is driven to rotate along the frame housing 11 to collect and discharge the spiral debris and fine debris that fall into the material receiving port 111 along the inclined discharge part 10. Then, the telescopic scraper 22 enters the accumulation channel 110, and the telescopic scraper 22 extends and fits against the accumulation channel 110 for scraping, turning the debris in the accumulation channel 110 out of the accumulation channel 110 along the compression arc channel 12 for discharge.

[0041] In the above technical solution, when the chain plate 21 moves along the frame housing 11 to transport metal waste, the telescopic scraper 22 will scrape along the accumulation channel 110 to scrape out the fine debris accumulated under the accumulation channel 110. Moreover, when the telescopic scraper 22 gradually retracts along the compression arc channel 12, it can directly scrape the fine debris along the compression arc channel 12 onto the chain plate 21 for transportation, so as to prevent the fine debris from accumulating in the accumulation channel 110 and breeding bacteria, maintaining the parameters of the coolant and not affecting the use of the tool and the workpiece.

[0042] As an embodiment provided by the present invention, a discharge port 112 is provided on the frame housing 11, and the telescopic scraper 22 extends when moving with the chain plate 21 to the discharge port 112.

[0043] Specifically, the discharge port 112 is provided on the inclined discharge part 10 and is vertically downward at the highest point of the inclined discharge part 10. The telescopic scraper 22 is compressed and locked after moving and scraping along the compression arc channel 12, and then pops out and extends when reaching the discharge port 112 to break free from the spiral long metal waste that is easily wound around the telescopic scraper 22, preventing the spiral long metal from staying on the telescopic scraper 22 for a long time and rusting, which affects the quality of the coolant. Moreover, when the telescopic scraper 22 pops out, the chain plate 21 will vibrate due to the inertia of the pop-out, shaking off the fine debris adsorbed on the telescopic scraper 22 and the chain plate 21 due to the surface tension of the coolant, reducing the residue of the fine debris.

[0044] When in use, the chain plate 21 is driven to rotate along the frame shell 11 to collect the spiral debris and fine debris that fall into the receiving port 111 and move them along the inclined discharge portion 10 to the discharge port 112, and then the telescopic scraper 22 pops out to discharge the debris, and then the telescopic scraper 22 enters the accumulation channel 110, and the telescopic scraper 22 extends to fit the accumulation channel 110 for scraping, and the debris in the accumulation channel 110 is turned out of the accumulation channel 110 along the compression arc 12 for discharge, and the telescopic scraper 22 is compressed and locked.

[0045] As the optimal embodiment provided by the present invention, the telescopic scraper 22 includes a telescopic sleeve 221 and an elastic inner scraper 222, between which a spring 224 is sleeved. The elastic inner scraper 222 is provided with an outward groove 2221 and a locking plate 2231. The elastic inner scraper 222 is driven to rub against the accumulation channel 110 and bend along the outward groove 2221, so that the locking plate 2231 is clamped on the telescopic sleeve 221 and locked.

[0046] Specifically, a locking groove 2211 is opened in the telescopic sleeve 221, and the locking plate 2231 is clamped in the locking groove 2211 for locking. A metal sheet can be set on the side of the elastic inner scraper 222 that fits the accumulation channel 110 to increase wear resistance. When the elastic inner scraper 222 moves with the chain plate 21 and slides into the compression arc 12, it will slide along the telescopic sleeve 221, and because of the friction force, the elastic inner scraper 222 will bend slightly along the outward groove 2221 to drive the locking plate 2231 to always fit the inner wall of the elastic inner scraper 222, and as the elastic inner scraper 222 continues to slide along the telescopic sleeve 221, the locking plate 2231 is clamped in the locking groove 2211 to lock the elastic inner scraper 222.

[0047] When in use, the chain plate 21 is driven to rotate along the frame shell 11 to collect the spiral debris and fine debris that fall into the receiving port 111 and move them along the inclined discharge part 10 to the discharge port 112, and then the elastic inner scraper 222 is unlocked, and the telescopic sleeve 221 pops out to discharge the debris, and then the elastic inner scraper 222 enters the accumulation channel 110, and the telescopic scraper 22 extends to fit the accumulation channel 110 for scraping, and the debris in the accumulation channel 110 is turned out of the accumulation channel 110 along the compression arc 12 for discharge, and when the elastic inner scraper 222 slides along the compression arc 12, the elastic inner scraper 222 will bend slightly along the outward groove 2221 to drive the locking plate 2231 to engage the locking groove 2211 and lock it.

[0048] As the optimal embodiment provided by the present invention, it also includes a discharge port 112, on which a reverse toggle plate 14 is arranged, and a locking lever 223 rotatably connected to a locking plate 2231 is movably connected inside the elastic inner scraper plate 222. The reverse toggle plate 14 rebounds after being toggled by the elastic inner scraper plate 222 to push the locking lever 223 to drive the locking plate 2231 to unlock.

[0049] Specifically, a support plate 141 is provided on the reverse toggle plate 14. Both the support plate 141 and the reverse toggle plate 14 are made of elastic metal plates. The elasticity of the support plate 141 is better than that of the reverse toggle plate 14. When the elastic inner scraping plate 222 retracts into the telescopic sleeve 221 and moves to the discharge port 112 along with the chain plate 21, it will first push against the support plate 141 to bend and deform, and cause the reverse toggle plate 14 to bend towards the discharge port 112. Then, when the elastic inner scraping plate 222 crosses the reverse toggle plate 14 and loses the bending force on the support plate 141, the support plate 141 will rebound and push against the reverse toggle plate 14 to push against the outer expansion groove 2221 on the elastic inner scraping plate 222 to close. At this time, the locking lever 223 will toggle the locking plate 2231 to slide out of the locking groove 2211 to achieve unlocking, so that the spring 224 pushes against the elastic inner scraping plate 222 to pop out.

[0050] During use, the chain plate 21 is driven to rotate along the housing 11 to collect the spiral debris and fine debris falling into the material collection port 111 and move them along the inclined discharge part 10 to the discharge port 112, so that the elastic inner scraping plate 222 pushes against the support plate 141 to bend and deform, and then crosses the reverse toggle plate 14. At this time, the support plate 141 will rebound and push against the reverse toggle plate 14 to unlock the elastic inner scraping plate 222 and pop out of the telescopic sleeve 221 to discharge the debris. Then, the elastic inner scraping plate 222 enters the accumulation channel 110, and the telescopic scraping plate 22 extends to fit the accumulation channel 110 for scraping, and discharges the debris in the accumulation channel 110 along the compression arc 12 out of the accumulation channel 110. When the elastic inner scraping plate 222 slides along the compression arc 12, the elastic inner scraping plate 222 will bend slightly along the outer expansion groove 2221 to drive the locking plate 2231 to be clamped in the locking groove 2211 for locking.

[0051] As the optimal embodiment provided by the present invention, the telescopic scraping plate 22 moves along with the chain plate 21, fits the accumulation channel 110 and maintains a constant length;

[0052] Narrowing plates 15 are provided at both ends of the accumulation channel 110. The telescopic scraping plate 22 includes an elastic inner scraping plate 222 and a telescopic sleeve 221. Deformation grooves 2223 are symmetrically opened at both ends of the elastic inner scraping plate 222. The elastic inner scraping plate 222 slides into the two narrowing plates 15 along with the chain plate 21 to squeeze the deformation grooves 2223 to deform and fit the telescopic sleeve 221 for locking.

[0053] Specifically, an elastic protrusion is clamped between two deformation grooves 2223. A folding groove 2222 is formed in the elastic protrusion. The folding groove 2222 is V-shaped. When the telescopic squeegee 22 enters the accumulation channel 110, the elastic inner squeegee 222 will slide along the two narrowing plates 15, causing the two deformation grooves 2223 to fold and deform, enabling the elastic protrusion to deform along the folding groove 2222, extending and fitting the telescopic sleeve 221 to lock in an extended state and maintaining a constant length (the constant length is that the elastic inner squeegee 222 fits the accumulation channel 110). When the elastic inner squeegee 222 moves along the accumulation channel 110, it can scrape the fine debris adsorbed on the accumulation channel 110 due to tension, further reducing the residue of the debris.

[0054] During use, the chain plate 21 is driven to rotate along the frame housing 11 to collect the spiral debris and fine debris falling into the material receiving port 111 and move them along the inclined discharge portion 10 to the discharge port 112, causing the elastic inner squeegee 222 to push against the support plate 141 to bend and deform. Subsequently, it passes over the reverse deflector 14. At this time, the support plate 141 will rebound and push against the reverse deflector 14 to unlock the elastic inner squeegee 222 and eject the telescopic sleeve 221 to discharge the debris. Then, the elastic inner squeegee 222 enters the accumulation channel 110. At this time, the elastic inner squeegee 222 compresses and fits the telescopic sleeve 221 along the narrowing plate 15 to lock. Then, the elastic inner squeegee 222 fits the accumulation channel 110 to scrape, turning the debris in the accumulation channel 110 out of the accumulation channel 110 along the compression arc 12 for discharge. When the elastic inner squeegee 222 slides along the compression arc 12, the elastic inner squeegee 222 will slightly bend along the outward expansion groove 2221 to drive the locking plate 2231 to be clamped and locked in the locking groove 2211.

[0055] As an embodiment provided by the present invention, it further includes a cooling circulation mechanism 3. The cooling circulation mechanism 3 includes a cooling water tank 31 provided on the frame housing 11. A plurality of inclined liquid discharge holes 131 are linearly arranged between the two. A static frame 32 is provided on the frame housing 11 and located inside the cooling water tank 31. A guide oil pipe 33 floating on the water surface is provided on the static frame 32.

[0056] Specifically, a connecting plate 13 is provided between the frame housing 11 and the cooling water tank 31. Drain holes are provided under the static frame 32 for discharging the coolant into the cooling water tank 31. The static frame 32 is located within the water level floating line of the cooling water tank 31 (when the cooling system is started or closed, the water level in the cooling water tank 31 is within the static frame 32). The inclined liquid discharge holes 131 are formed on the connecting plate 13. The static frame 32 is provided on the connecting plate 13. The coolant scraped by the elastic inner squeegee 222 in the accumulation channel 110 will mix with the oil fluid of the machine tool (the oil fluid is composed of the protective oil of the workpiece, the lubricating oil of the machine tool, etc.), and then be discharged through the inclined liquid discharge holes 131 into the static frame 32 for static separation of oil and water, and the oil fluid is gathered in the static frame 32 for convenient treatment.

[0057] In use, the chain plate 21 is driven to rotate along the frame housing 11 to collect the spiral debris and fine debris falling into the material receiving port 111 and move them along the inclined discharge portion 10 to the discharge port 112, so that the elastic inner scraper 222 pushes against the support plate 141 and bends and deforms. Then it passes over the reverse deflector plate 14. At this time, the support plate 141 will rebound and push against the reverse deflector plate 14 to unlock the elastic inner scraper 222, and the telescopic sleeve 221 will pop out to discharge the debris. Then the elastic inner scraper 222 enters the accumulation channel 110. At this time, the elastic inner scraper 222 is compressed and fitted along the narrowing plate 15 to lock the telescopic sleeve 221. Then the elastic inner scraper 222 scrapes along the accumulation channel 110, and the debris in the accumulation channel 110 is turned out of the accumulation channel 110 along the compression arc 12 for discharge. When the elastic inner scraper 222 slides along the compression arc 12, the elastic inner scraper 222 will be slightly bent along the outward expansion groove 2221 to drive the locking plate 2231 to be clamped in the locking groove 2211 for locking and recycle again. And the coolant in the accumulation channel 110 will be discharged along the drain hole 131 into the static frame 32 for static settlement for the next use.

[0058] As the optimal embodiment provided by the present invention, it further includes a chain plate 21, and the oil guide pipe 33 moves with the chain plate 21 to pump oil.

[0059] A rotating shaft 20 is sleeved inside the chain plate 21. A paddle 342 is arranged on the rotating shaft 20. A closed cover 341 is fixedly communicated with the oil guide pipe 33. The paddle 342 is rotatably connected inside the closed cover 341, and the paddle 342 rotates as the rotating shaft 20 rotates.

[0060] Specifically, the rotating shaft 20 is rotatably connected to the frame housing 11. A paddle 342 is arranged on the rotating shaft 20. When the chain plate 21 is driven to rotate by a motor, the rotating shaft 20 will rotate together to drive the paddle 342 to rotate. The paddle 342 rotates inside the closed cover 341 to drive the oil guide pipe 33 to suck the waste oil in the static frame 32. A top suction cup 331 is fixedly communicated with the oil guide pipe 33. A floating plate 332 is arranged on the top suction cup 331. The floating plate 332 floats on the water surface and sinks to the bottom of the oil. When the oil liquid covers the top suction cup 331, the excessive waste oil will be pumped away by the oil guide pipe 33.

[0061] During use, the chain plate 21 is driven to rotate along the housing 11 to collect the spiral debris and fine debris falling into the material receiving port 111 and move them along the inclined discharging portion 10 to the discharging port 112, so that the elastic inner scraper 222 is pushed against the support plate 141 to bend and deform. Then, it passes over the reverse deflector plate 14. At this time, the support plate 141 will rebound and push against the reverse deflector plate 14 to unlock the elastic inner scraper 222, and the telescopic sleeve 221 will pop out to discharge the debris. Then, the elastic inner scraper 222 enters the accumulation channel 110. At this time, the elastic inner scraper 222 compresses and fits the telescopic sleeve 221 along the narrowing plate 15 to lock. Then, the elastic inner scraper 222 scrapes along the accumulation channel 110, and the debris in the accumulation channel 110 is turned out of the accumulation channel 110 along the compression arc 12 for discharge. When the elastic inner scraper 222 slides along the compression arc 12, the elastic inner scraper 222 will bend slightly along the outward expansion groove 2221 to drive the locking plate 2231 to be locked in the locking groove 2211 for recycling. The coolant in the accumulation channel 110 will be discharged along the drain hole 131 into the static frame 32 for static settlement. When the oil covers the top suction cup 331, the rotating shaft 20 drives the paddle 342 to rotate in the closed cover 341 to extract the excess oil.

[0062] As the optimal embodiment provided by the present invention, it further includes a telescopic scraper 22. A quick drainage cover 30 is rotatably connected to the drain hole 131. A spiral rubber strip 301 is sleeved on the quick drainage cover 30. The quick drainage cover 30 rotates as the telescopic scraper 22 slides to move along the drain hole 131.

[0063] Specifically, the quick drainage cover 30 is made of stainless steel. Filter holes 302 are provided on the quick drainage cover 30 to intercept fine debris. The drain hole 131 is inclined to allow the fine debris to fall along the quick drainage cover 30. When the quick drainage cover 30 does not receive a pushing force, it will fall along the inclined drain hole 131 due to gravity. When the chain plate 21 passes by, the telescopic sleeve 221 will push against the highest point of the inclined quick drainage cover 30 to make it rotate. At this time, due to the spiral rubber strip 301, the quick drainage cover 30 will move along the high point of the drain hole 131 to promote the discharge of the coolant. Then, the drain hole 131 will fall again to achieve reciprocation.

[0064] During use, the chain plate 21 is driven to rotate along the frame housing 11 to collect the spiral debris and fine debris falling into the material receiving port 111 and move them along the inclined discharge portion 10 to the discharge port 112, causing the elastic inner scraper 222 to push against the support plate 141 and bend it. Subsequently, it passes over the reverse deflector plate 14. At this time, the support plate 141 rebounds and pushes against the reverse deflector plate 14 to unlock the elastic inner scraper 222, and the telescopic sleeve 221 pops out to discharge the debris. Then, the elastic inner scraper 222 enters the accumulation channel 110. At this time, the elastic inner scraper 222 compresses and fits along the narrowing plate 15 to lock the telescopic sleeve 221. Then, the elastic inner scraper 222 scrapes against the accumulation channel 110, turning the debris in the accumulation channel 110 out of the accumulation channel 110 along the compression arc 12 for discharge. When the elastic inner scraper 222 slides along the compression arc 12, the elastic inner scraper 222 will bend slightly along the outward expansion groove 2221 to drive the locking plate 2231 to engage and lock in the locking groove 2211 for another cycle. The coolant in the accumulation channel 110 will be discharged along the drain hole 131 into the static frame 32 for static settlement. When the oil submerges the top suction cup 331 and at the same time the rotating shaft 20 drives the paddle 342 to rotate in the closed cover 341 to extract the excessive oil. When the chain plate 21 passes by the drain hole 131, the telescopic sleeve 221 will push against the highest point of the inclined quick drainage cover 30 to make it rotate, driving the quick drainage cover 30 to move.

[0065] As the optimal embodiment provided by the present invention, a piston 225 is provided on the elastic inner scraper 222, and a water spraying port 226 is opened on the telescopic sleeve 221. The piston 225 reciprocates along the telescopic sleeve 221 as the elastic inner scraper 222 moves to spray the coolant towards one of the adjacent telescopic scrapers 22.

[0066] Specifically, a blocking plate 24 is provided on the chain plate 21, and an inclined surface 241 is opened on the blocking plate 24. A pre-pressing channel 101 is provided on the inclined discharge portion 10. The pre-pressing channel 101 compresses the telescopic scraper 22 without causing the locking plate 2231 to engage in the locking groove 2211, so that when the telescopic scraper 22 enters the accumulation channel 110, it extends through the water spraying port 226 to pump water. When the elastic inner scraper 222 passes through the compression arc 12, the inclined surface 241 on the blocking plate 24 will fit and incline along the rotating shaft 20, causing the blocking plate 24 to fit and block the water spraying port 226. Then, the elastic inner scraper 222 compresses along the compression arc 12, reducing the space and increasing the pressure inside the piston 225 and the telescopic sleeve 221. Subsequently, the chain plate 21 leaves the rotating shaft 20, and the water spraying port 226 opens to release the pressurized water flow to wash away the fine debris on the long spiral metal waste on the chain plate 21, preventing the fine debris from flying out when the subsequent telescopic scraper 22 pops out.

[0067] In use, the chain plate 21 is driven to rotate along the frame housing 11 to collect the spiral debris and fine debris falling into the material receiving port 111 and move them along the inclined discharge portion 10 to the discharge port 112, so that the elastic inner scraper 222 pushes against the support plate 141 and bends it. Then, it passes over the reverse deflecting plate 14. At this time, the support plate 141 will rebound and push against the reverse deflecting plate 14 to unlock the elastic inner scraper 222, and the telescopic sleeve 221 will pop out to discharge the debris. Then, the elastic inner scraper 222 enters the pre-pressurization channel 101 to compress the telescopic scraper 22 and extends into the accumulation channel 110 to pump water. Then, the elastic inner scraper 222 compresses and fits along the narrowing plate 15 to lock the telescopic sleeve 221. Then, the elastic inner scraper 222 fits against the accumulation channel 110 to scrape, and the debris in the accumulation channel 110 is turned out of the accumulation channel 110 along the compression arc 12 for discharge. When the elastic inner scraper 222 slides along the compression arc 12, the elastic inner scraper 222 will be slightly bent along the outward expansion groove 2221 to drive the locking plate 2231 to be clamped and locked in the locking groove 2211 for another cycle. At the same time, the inclined surface 241 on the blocking plate 24 will be inclined and fitted along the rotating shaft 20 to block the water spray port 226. Then, the elastic inner scraper 222 compresses along the compression arc 12. Then, the chain plate 21 leaves the rotating shaft 20, and the water spray port 226 is opened to release the pressurized water flow. The coolant in the accumulation channel 110 will be discharged along the drain hole 131 into the static frame 32 for static settlement. When the oil liquid covers the top suction cup 331, at the same time, the rotating shaft 20 drives the paddle 342 to rotate in the closed cover 341 to extract the excessive oil liquid. When the chain plate 21 passes by the drain hole 131, the telescopic sleeve 221 will push against the highest point of the inclined quick-drain cover 30 to rotate it, so as to drive the quick-drain cover 30 to move.

[0068] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
