Description

Technical Field

[0001] The present invention relates to a precision high-speed hydraulic machine tool, and particularly to an internal flexible precision high-speed hydraulic machine tool applied in the field of machine tools. Background Art

[0002] The internal flexible precision high-speed hydraulic machine tool is an advanced machine tool that combines high precision, high speed, flexible machining capabilities, and hydraulic drive technology. It is mainly used for the efficient precision machining of complex parts. During the actual machining process of the machine tool, cutting fluid is usually used to assist in cooling, lubricating, chip removal, and rust prevention.

[0003] The specification of Chinese Utility Model Patent CN215847212U discloses a cutting fluid solid-liquid separation device for a numerical control machine tool. This device uses a lower scraper to scrape the iron filings on the lower filter plate into the first diversion groove, and the iron filings are washed into the iron filing box from the first diversion groove. The cutting fluid flows into the liquid storage tank through the lower filter plate, having the advantage of classified treatment.

[0004] The specification of Chinese Utility Model Patent CN212043783U discloses a numerical control machine tool. By setting a chip removal device and a filter box, the cutting fluid is separated from the iron filings, reducing the debris content in the cutting fluid, lowering the probability of damage to the product by the cutting fluid, thereby improving the product quality and the qualified rate of the product.

[0005] For the existing devices to clean the filter screen, the surface of the filter screen is usually cleaned by the push of a scraper. However, since there may be flat brittle materials in the waste chips, during the scraping and pushing process, the flat brittle waste chips will be further broken, resulting in their passing through the filter screen and causing pollution to the filtered cutting fluid. If a track device is used for filtration, the waste chips blocked on the surface of the filtration track are also separated by the gravity during the track commutation, and the cleaning degree is insufficient. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is how to efficiently clean the filtration structure on the basis of filtering the mixture of cutting fluid and waste chips.

[0007] To solve the above problems, the present invention provides an internally flexible precision high-speed hydraulic machine tool, which includes a machine tool main body. Below the machine tool main body, there is a cutting pool with an open top design. Inside the cutting pool, there are two symmetrically arranged conveyor rollers. The surfaces of the two conveyor rollers are connected by a filtering track. In the middle between the two conveyor rollers, there is a partition that is rotationally sealed. At the bottom of the partition, there is a toggle plate installed through symmetrically arranged pushing components, and the toggle plate is located above the lower layer of the filtering track. On one inner wall of the cutting pool, at a position between the partition and the upper layer of the filtering track, there is an outlet pipe for circulating cutting fluid. On the inner wall of the cutting pool, there are multiple rockers installed rotatably below the lower layer of the filtering track, and on the surface of each rocker, there is an isolation component. The end of each rocker extends to the outside of the cutting pool, and the surfaces of multiple rockers are connected by a conveyor belt. The length value of each isolation component is equal to the horizontal distance value between adjacent two rockers. The surface of the filtering track is provided with depressions, and at the bottom of the filtering track, there is a layer of electromagnetic shielding material; The pushing component includes a waterproof box. Inside the waterproof box, there is a micro electro-telescopic rod. The output end of the micro electro-telescopic rod is connected to a movable shaft frame. The two ends of the movable shaft frame are respectively hinged to the surfaces of the partition and the toggle plate.

[0008] In the above internally flexible precision high-speed hydraulic machine tool, through multiple structural designs, efficient circulation of cutting fluid and automatic cleaning of waste chips are achieved, and the protection of the filtering track and the cleaning quality are taken into account through a non-contact disturbance cleaning method.

[0009] As a further improvement of the present application, when the toggle plate moves down to the maximum distance value, the toggle plate is located above the lower layer of the filtering track. When the isolation component swings horizontally, the sum of the horizontal projection areas of the isolation component and the rocker is the same as the inner wall area of the cutting pool.

[0010] As a further improvement of the present application, on one outer wall of the cutting pool, there is a first motor and a second motor installed, and the output end of the first motor is connected to the end of one of the conveyor rollers, and the output end of the second motor is connected to the end of one of the rockers.

[0011] As a further improvement of the present application, the isolation component includes a fixed plate fixedly installed on the surface of the rocker with a hollow interior, and the fixed plate communicates with the rocker. Inside the inner wall of the fixed plate, there is a movable plate slidably installed. On one surface of the movable plate, there is a cleaning part installed through a connecting rod. On the surface of the cutting pool, there is a vertical plate installed. On the surface of the movable plate, there is an elastic reset part installed, and the tail end of the elastic reset part is connected to the surface of the rocker.

[0012] As a further improvement of the present application, on the surface of the vertical plate, there is a suction pump installed. The output end of the suction pump is connected to a branch hose, and the tail end of the branch hose is connected to the end of the rocker through a rotary joint.

[0013] When the movable plate is placed vertically, the tail end of the cleaning piece is located at the top end of the fixed plate surface; when the movable plate is placed horizontally, the tail end of the cleaning piece is located at the tail end of the fixed plate surface.

[0014] As a further improvement of the present application, an annular permanent magnet is sleeved on the surface of the conveying roller, and an arc-shaped magnetic conductive groove is provided on the surface of the partition close to the annular permanent magnet, and magnetic fluid is injected into the magnetic conductive groove to form a magnetic fluid seal.

[0015] As another improvement of the present application, a No. 3 motor is installed on the outer wall of the other side of the cutting pool, and the output end of the No. 3 motor is connected to a screw arranged parallel to the rocker arm. The surface of the screw is threadedly connected to a scraper in contact with the bottom wall of the cutting pool. The bottom side of the cutting pool is connected to a discharge pipe through a feed port. A discharge port is provided at the bottom of the discharge pipe. A water storage pipe is rotatably installed inside the discharge pipe, and a surrounding baffle is installed on the surface of the water storage pipe. A water inlet pipe arranged at intervals from the baffle is installed around and through the surface of the water storage pipe, and a baffle net and a one-way valve are installed inside the water inlet pipe.

[0016] As another improvement of the present application, a No. 4 motor is installed at one end of the discharge pipe, and a reflux pipe is installed at one end of the water storage pipe, and the tail end of the reflux pipe extends to the space below the partition, and a water pump is installed in the middle of the reflux pipe.

[0017] To summarize, the filter belt in the cutting pool is driven by the conveyor roller to form an upper and lower double-layer structure. The partition and the conveyor roller use magnetic fluid seals to ensure rotational sealing. When cleaning waste chips, the micro-electric extension rod drives the toggle plate to disturb the water body to remove waste chips in the depression of the filter belt. At the same time, the No. 2 motor drives the isolation component to expand horizontally to isolate and precipitate waste chips. The suction air pump realizes waste chip suction through the hollow rocker. In addition, the scraper and discharge pipe mechanism driven by the No. 3 motor realizes waste chip dehydration and separation through the rotation of the baffle and the water storage pipe. When the No. 4 motor drives the water storage pipe to rotate, the filtered cutting fluid returns to the cutting pool through the reflux pipe. The electromagnetic shielding material layer can prevent electromagnetic interference, ensure the stable operation of the system, and realize the full automation of waste chip cleaning and cutting fluid circulation, significantly improving cleaning efficiency and ensuring processing accuracy.

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method: Figures 1-5The invention discloses an internal flexible precision high-speed hydraulic machine tool, comprising a machine tool body 1, a cutting pool 2 with an open top is installed under the machine tool body 1, two symmetrically arranged conveying rollers 7 are installed inside the cutting pool 2, the surfaces of the two conveying rollers 7 are connected by a filter belt 6, and a partition 8 is rotatably sealed in the middle of the two conveying rollers 7, and a toggle plate 9 is installed at the bottom of the partition 8 through a symmetrically arranged pushing assembly, and the toggle plate 9 is located above the lower layer of the filter belt 6, and an outlet pipe for circulating cutting fluid is installed on the inner wall of one side of the cutting pool 2 at a position between the partition 8 and the upper layer of the filter belt 6, a plurality of rockers 10 are rotatably installed on the inner wall of the cutting pool 2, and an isolation assembly 11 is installed on the surface of each rocker 10, the end of each rocker 10 extends to the outside of the cutting pool 2 and the surfaces of the plurality of rockers 10 are connected by a conveyor belt, the length of each isolation assembly 11 is equal to the horizontal distance between two adjacent rockers 10, the surface of the filter belt 6 is provided with a depression, and a layer of electromagnetic shielding material is installed at the bottom of the filter belt 6; The pushing assembly includes a waterproof box, inside which a micro electric extension rod 12 is installed. The output end of the micro electric extension rod 12 is connected to a movable shaft frame 13, and the two ends of the movable shaft frame 13 are respectively hinged to the surfaces of the partition 8 and the toggle plate 9.

[0022] An annular permanent magnet is sleeved on the surface of the conveying roller 7 , and an arc-shaped magnetic conductive groove is provided on the surface of the partition plate 8 close to the annular permanent magnet. Magnetic fluid is injected into the magnetic conductive groove to form a magnetic fluid seal.

[0023] When the toggle plate 9 moves down to the maximum distance value, the toggle plate 9 is located above the lower layer of the filter track 6. When the isolation assembly 11 swings horizontally, the sum of the horizontal projection areas of the isolation assembly 11 and the rocker 10 is the same as the inner wall area of the cutting pool 2.

[0024] A No. 1 motor 3 and a No. 2 motor 4 are installed on one side outer wall of the cutting pool 2, and the output end of the No. 1 motor 3 is connected to the end of one of the conveying rollers 7, and the output end of the No. 2 motor 4 is connected to the end of one of the rocking arms 10.

[0025] Specifically, since the conveying roller 7 and the partition 8 are connected in a rotating sealed manner, the space formed between the upper layer of the filter belt 6 and the partition 8 is the purification chamber, and the space formed between the lower layer of the filter belt 6 and the horizontally placed isolation assembly 11 is the clean chamber; When machining a machine tool, the mixture of waste chips and cutting fluid falls onto the upper layer of the filter track 6 together. Under the filtering and intercepting action of the filter track 6, the filtered cutting fluid can enter the purification chamber, and then is discharged from the purification chamber through the outlet pipe for recycling. The waste chips intercepted in the recesses of the filter track 6 can be transferred downward through the rotation of the filter track 6. At this time, the micro-electric telescopic rod 12 in the pushing component is started to reciprocate in the horizontal direction for elongation and retraction actions, driving the movable shaft frame 13 to elongate and retract in the vertical direction, thereby driving the dialing plate 9 to swing up and down in the water body in the space below the partition plate 8 in the cutting pool 2, so as to form a disturbing water flow effect, which plays a disturbing role on the filter track 6 immersed therein and the recesses on its surface (as Figure 6 shown), and then the waste chips in the recesses are cleaned out. Through a non-contact method, a more thorough waste chip cleaning operation can be realized.

[0026] In addition, in order to avoid the influence on the cleaning quality caused by the disturbance when the water body in the space below the partition plate 8 contains waste chips. Because when disturbing in the state that the water body contains waste chips, the waste chips will float up, and the water body used to immerse the filter track 6 and loosen the waste chips in the recesses will also contain the waste chips left by the previous cleaning operation, which will re-adhere to the surface of the filter track 6 and affect the cleaning quality. Before starting the pushing component, the second motor 4 is started to drive the isolation component 11 to be in a horizontal placement state, so that the isolation component 11 can isolate the precipitated waste chips and the upper static water body, and then the pushing component is started. When performing dynamic disturbance cleaning, the floating and mixing of the already precipitated waste chips and secondary adhesion can be avoided, thereby ensuring the cleaning quality.

[0027] Figures 7-8 It is shown that the isolation component 11 includes a fixed plate 111 fixedly installed on the surface of the hollow rocker 10, and the fixed plate 111 communicates with the rocker 10. A movable plate 112 is slidably installed on the inner wall of the fixed plate 111. One surface of the movable plate 112 is provided with a cleaning member 113 through a connecting rod. A vertical plate is installed on the surface of the cutting pool 2. An elastic reset member 114 is installed on the surface of the movable plate 112, and the tail end of the elastic reset member 114 is connected to the surface of the rocker 10.

[0028] A suction pump 5 is installed on the surface of the vertical plate. The output end of the suction pump 5 is connected with a branch hose (not shown in the figure), and the tail end of the branch hose is connected to the end of the rocker 10 through a rotary joint.

[0029] When the movable plate 112 is vertically placed, the tail end of the cleaning member 113 is located at the top of the surface of the fixed plate 111. When the movable plate 112 is horizontally placed, the tail end of the cleaning member 113 is located at the tail end of the surface of the fixed plate 111.

[0030] Specifically, since the isolation component 11 has a certain length, and as the filtering operation continues, the thickness of the waste chips at the bottom wall of the cutting pool 2 will increase, which may submerge the bottom part of the isolation component 11. Therefore, when switching from the vertical state to the horizontal state, the surface of the isolation component 11 will disturb some waste chips and float with the horizontally placed isolation component 11 into the water body between the isolation component 11 and the partition plate 8. During subsequent disturbances, it will affect the cleaning quality of the filtering track 6.

[0031] To solve the above problems, a retractable and movable isolation component 11 is designed. When the isolation component 11 is about to switch to the horizontal state, first rotate the rocker 10 to make it in the horizontal state. At this time, the fixed plate 111 is in a shorter state and will not contact the accumulated waste chips. Therefore, the waste chips will not be lifted when rotating. Use the suction pump 5 to inflate the fixed plate 111, drive the movable plate 112 to extend, and drive to isolate the space below the partition plate 8, which is convenient for subsequent disturbance cleaning operations.

[0032] After that, it is necessary to restore the isolation component 11 to the vertical state. At this time, the suction pump 5 deflates the fixed plate 111. Under the action of the elastic resetting member 114, which can be a spring or other components, the movable plate 112 is reset. During the reset process, the flake-shaped waste chips adhered to the surfaces of the cleaning member 113 and the movable plate 112 are scraped off.

[0033] The second implementation method: Figures 9-10 It is shown that a third motor 15 is installed on the outer wall of the other side of the cutting pool 2. The output end of the third motor 15 is connected to a lead screw arranged in parallel with the rocker 10. The surface of the lead screw is threadedly connected with a scraper 14 in contact with the bottom wall of the cutting pool 2. One side of the bottom of the cutting pool 2 is connected to a discharge pipe 16 through a feed port 161. A discharge port 162 is provided at the bottom of the discharge pipe 16. A water storage pipe 165 is rotatably installed inside the discharge pipe 16. A surrounding baffle 163 is installed on the surface of the water storage pipe 165, and a water inlet pipe arranged at intervals with the baffle 163 is installed around and through the surface of the water storage pipe 165. A retaining net 164 and a one-way valve are installed inside the water inlet pipe.

[0034] One end of the discharge pipe 16 is installed with a fourth motor (not shown in the figure), and one end of the water storage pipe 165 is installed with a reflux pipe. The tail end of the reflux pipe extends to the space below the partition plate 8, and a water pump is installed in the middle of the reflux pipe.

[0035] Different from the first implementation method, this implementation method is mainly used to discharge the waste chips on the bottom wall of the cutting pool 2 in the first implementation method.

[0036] Specifically, when cleaning the waste chips on the bottom wall of the cutting pool 2, the No. 3 motor 15 is started to drive the scraper 14 on the surface of the screw to move, so that the waste chips on the bottom wall of the cutting pool 2 can be pushed to the feed port 161 and enter the discharge pipe 16. As the No. 4 motor drives the water storage pipe 165 to rotate, the space between the two adjacent baffles 163 accommodates a mixture of water and waste chips. The water is filtered by the baffle 164 and then enters the water storage pipe 165 in one direction. The waste chips intercepted outside are transferred to the position of the discharge port 162 through rotation and then discharged. The water entering the water storage pipe 165 is returned to the space below the partition 8 in the cutting pool 2 through the reflux pipe and the water pump, and the water level in the space below the partition 8 continues to be stable (such as Figure 11 shown).

[0037] In summary, through the multiple structural designs, efficient circulation of cutting fluid and automatic cleaning of waste chips are achieved. The filter belt 6 in the cutting pool 2 is driven by the conveying roller 7 to form an upper and lower double-layer structure. The partition 8 and the conveying roller 7 use magnetic fluid seals to ensure rotational sealing. When cleaning waste chips, the micro electric extension rod 12 drives the toggle plate 9 to disturb the water body to remove the waste chips in the depression of the filter belt 6. At the same time, the No. 2 motor 4 drives the isolation component 11 to expand horizontally to isolate and precipitate the waste chips. The suction air pump 5 realizes waste chip suction through the hollow rocker 10. In addition, the scraper 14 and the discharge pipe 16 mechanism driven by the No. 3 motor 15 realize waste chip dehydration and separation through the rotation of the baffle 163 and the water storage pipe 165. When the No. 4 motor drives the water storage pipe 165 to rotate, the filtered cutting fluid returns to the cutting pool 2 through the reflux pipe. The electromagnetic shielding material layer can prevent electromagnetic interference, ensure the stable operation of the system, realize the full automation of waste chip cleaning and cutting fluid circulation, significantly improve the cleaning efficiency and ensure the processing accuracy.

[0038] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
