Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and in particular to a hydraulic valve core cutting device and a processing technology thereof. Background Art

[0002] The hydraulic valve core is the core component of the hydraulic valve. Its design and performance directly impact the pressure, flow, and directional control accuracy of the hydraulic system. The valve core adjusts the valve opening through relative motion with the valve body, thereby controlling the flow of the hydraulic medium. It is widely used in engineering machinery, metallurgical equipment, hydraulic support, and other fields.

[0003] The hydraulic valve core needs to be axially cut multiple times during the manufacturing process. When the valve core or other metal shaft parts are axially cut, a large amount of cutting debris will be generated. The debris will fall to the recovery area together with the cutting fluid, and the debris and cutting fluid will be separated and then recycled.

[0004] For example, the existing patent with application number 202021839996.2 and name “A simple metal cutting machine for collecting debris” controls the airflow and water flow by controlling the three-way valve to realize the spraying of cutting fluid or the spraying of airflow to facilitate the collection of debris; a workbench is fixedly installed on the machine tool body, and the bottom end of the workbench is fixedly connected to a funnel-shaped liquid-chip separation box, a sieve-like mesh filter is provided inside the funnel-shaped liquid-chip separation box, and a debris collection box is provided at the lower end of the outer side of the funnel-shaped liquid-chip separation device to realize liquid-chip separation.

[0005] The aforementioned prior art and prior art all suffer from a common drawback: because the chips gradually fall down and are discharged into the collection box along with the cutting fluid, the chips become a fluffy pile after separation from the cutting fluid. This fluffy pile of chips contains more cutting fluid, which reduces the separation quality of the chips and cutting fluid. Therefore, in actual machining processes, to separate more cutting fluid from the chips, a dedicated squeezing mechanism is used to separately squeeze the fluffy chips after separation to drain more cutting fluid from the chips, thereby improving the separation quality of the chips and cutting fluid. However, this separate squeezing of the chips after separation consumes additional operator time and energy, increasing the operator's workload and reducing work efficiency. Therefore, how to separate the fluffy chips after separation without requiring the operator to perform a separate squeezing operation, thereby draining more cutting fluid from the chips and improving the separation quality and work efficiency, is an urgent technical problem to be solved. Summary of the Invention

[0006] The purpose of the present invention is to provide a hydraulic valve core cutting device and a processing technology thereof to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a hydraulic valve core cutting device, comprising a base, a clamping mechanism for fixing the valve core, and an X-axis motion assembly for driving the cutting tool to reciprocate axially along the valve core. A toothed plate is fixedly mounted on the X-axis motion assembly, a gear meshing with the toothed plate is rotatably disposed in the base, and an eccentric shaft is disposed on the gear; A baffle is provided in the base, and an extrusion plate opposite to the baffle is slidably provided, and a rotating arm is rotatably connected between the extrusion plate and the eccentric shaft; A filter assembly with one end overlapping the baffle is rotatably provided in the base, and a debris receiving area is formed between the filter assembly, the baffle and the extrusion plate. The debris generated during cutting enters the debris receiving area and filters out the cutting fluid. During the resetting process of the cutting blade, the tooth plate drives the gear to rotate so that the rotating arm pulls the extrusion plate toward the baffle to squeeze the debris.

[0008] In the above-mentioned hydraulic valve core cutting device, the baffle is elastically swingingly arranged in the base, a limit plate is fixedly installed on the bottom of the baffle, and one end of the filter assembly is overlapped on the limit plate. As the debris continues to enter the debris receiving area, the extrusion plate squeezes the debris toward the baffle, driving the debris to push the baffle to swing elastically so that the filter assembly is disengaged from the limit plate and rotates downward to open the debris receiving area.

[0009] The above-mentioned hydraulic valve core cutting device, the extrusion plate includes a fixedly arranged pushing square rod, the filter assembly includes a rotatably arranged main body plate, and a high plane is formed on the top of the end of the main body plate away from the baffle. During cutting, the extrusion plate drives the pushing square rod to move toward the high plane until the bottom surface of the pushing square rod abuts against the top surface of the high plane, thereby driving the pushing square rod to push the filter assembly to reset after rotating downward.

[0010] In the above-mentioned hydraulic valve core cutting device, a fixed block is fixedly installed in the base, and a limiting spring is fixedly connected between the fixed block and the limiting plate.

[0011] The above-mentioned hydraulic valve core cutting device has two tooth plates and two gears, which are meshed one-to-one. Both gears are provided with eccentric shafts. There are two rotating arms, which are rotatably connected to the two eccentric shafts one-to-one. The extrusion plate is located between the two rotating arms.

[0012] The above-mentioned hydraulic valve core cutting device has two groups of vertical guide rails symmetrically arranged in the front and back, fixedly installed in the base, and the number of vertical guide rails in each group is two and arranged up and down. Two horizontal rods arranged up and down are inserted on the extrusion plate, and a vertical sliding block is installed at both ends of the two horizontal rods. The four vertical sliding blocks are slidably arranged in the four vertical guide rails in a one-to-one manner, and the connection position of the rotating arm and the extrusion plate is located between the two horizontal rods.

[0013] The above-mentioned hydraulic valve core cutting device, the filter assembly also includes a push-pull mechanism fixedly installed in the main body plate and a first filter plate elastically slidably arranged on the push-pull mechanism, the push-pull mechanism is located below the first filter plate and abuts against the bottom of the first filter plate, and the filter assembly is disengaged from the limit plate and rotated downward, driving the first filter plate to elastically slide above the push-pull mechanism to cause the first filter plate to vibrate.

[0014] The above-mentioned hydraulic valve core cutting device, the push-pull mechanism includes a box body fixedly connected to the main plate, the first filter plate is slidably engaged with the box body, and a second filter plate is elastically slidably provided in the box body to abut the bottom of the first filter plate.

[0015] The above-mentioned hydraulic valve core cutting device, the first filter plate includes a plurality of trapezoidal plates fixedly mounted on its bottom, the second filter plate includes a plurality of hemispheres fixedly mounted on its top, the tops of the plurality of hemispheres elastically abut against the bottom of the first filter plate, and when the first filter plate elastically slides above the push-pull mechanism, the hemispheres elastically pass over the trapezoidal plates and hit the bottom of the first filter plate.

[0016] A hydraulic valve core cutting process, comprising the above-mentioned hydraulic valve core cutting device, comprises the following steps: S1: Installation: First, the X-axis motion assembly and the cutting tool are in the initial position. At this time, the cutting tool is farthest from the clamping mechanism. Then, the valve core to be cut is fixed to the clamping mechanism. S2: Chip cutting: The clamping mechanism is driven by the driving mechanism to rotate, thereby driving the valve core to rotate. Then, the X-axis motion assembly drives the cutting tool to move toward the valve core. At this time, the X-axis motion assembly drives the tooth plate to drive the gear to rotate. The gear pushes the extrusion plate to slide away from the baffle through the rotating arm to enlarge the top opening of the chip receiving area. Before the cutting tool contacts the valve core, the tooth plate and the gear separate. At this time, the top opening of the chip receiving area covers the entire valve core. Then, the cutting tool cuts the valve core. The chips generated during cutting fall into the chip receiving area with the cutting fluid. The cutting fluid falls through the filter assembly, while the chips continue to remain in the chip receiving area. S3: Extruding chips: After cutting is completed, the X-axis motion assembly drives the cutting tool to move away from the valve core until it resets. During this process, the X-axis motion assembly drives the tooth plate to drive the gear to rotate so that the rotating arm pulls the extrusion plate toward the baffle to squeeze the chips, so that the cutting fluid in the chips is squeezed out.

[0017] Beneficial effects: 1. In the above-mentioned technical solution, the present invention provides a hydraulic valve spool cutting device and a processing process thereof. The present invention provides a debris receiving area and, during the cutting process, cleverly utilizes an X-axis motion assembly to drive the movement of the cutting blade, thereby causing the volume of the debris receiving area to increase and decrease. When the cutting blade cuts the valve spool, the volume of the debris receiving area increases and covers the entire valve spool. As a result, debris generated during cutting, along with cutting fluid, falls into the debris receiving area. The cutting fluid is filtered out by the filter assembly, and the debris remains in the debris receiving area. When cutting is complete, the X-axis motion assembly drives the cutting blade back to its original position, and the volume of the debris receiving area decreases, squeezing out the debris remaining in the debris receiving area and automatically squeezing out the remaining cutting fluid. Because the chip squeezing is automatically achieved throughout the valve spool cutting process, the operator does not need to separately squeeze out the fluffy debris, thus saving the operator's time and energy. Furthermore, more cutting fluid is discharged from the debris, thereby improving the separation quality of the debris and cutting fluid and enhancing work efficiency.

[0018] 2. The present invention sets the baffle plate to be elastically rotatable, so that the debris receiving area can be automatically opened after the debris is squeezed to a certain extent, thereby realizing automatic discharge of the extruded debris. At the same time, by providing a high plane protruding from the top surface of the filter assembly and fixing a pushing square rod corresponding to the high plane on the extrusion plate, when the filter assembly is rotated downward to open the debris receiving area, when cutting again, the extrusion plate drives the pushing square rod to push the filter assembly to rotate. When the bottom surface of the pushing square rod is aligned with the high plane, the end of the filter assembly passes over the limit plate and re-engages with the top surface of the limit plate, so that the filter assembly is automatically reset, thereby realizing the reset of the debris receiving area. It can be seen that the extrusion of the debris, the discharge of the extruded debris, and the reset of the debris receiving area are all achieved during the cutting process, and no additional operation of the staff is required throughout the process, and there is no need to set up additional drive components for control, which can greatly improve convenience and cost.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] First embodiment: like Figure 1-18 As shown, an embodiment of the present invention provides a hydraulic valve core cutting device, comprising a base 1, a clamping mechanism 6 for fixing the valve core, and an X-axis motion assembly for driving a cutting blade 10 to reciprocate in the axial direction of the valve core. A toothed plate 14 is fixedly mounted on the X-axis motion assembly. A gear 15 is rotatably provided in the base 1 and meshes with the toothed plate 14. An eccentric shaft 1502 is provided on the gear 15. A baffle 16 is provided in the base 1, and an extrusion plate 17 is slidably provided opposite to the baffle 16. A rotating arm 18 is rotatably connected between the extrusion plate 17 and the eccentric shaft 1502. A filter assembly with one end overlapping the baffle 16 is rotatably provided in the base 1. A debris receiving area is formed between the filter assembly, the baffle 16 and the extrusion plate 17. The debris generated during cutting enters the debris receiving area and filters out the cutting fluid. During the resetting process of the cutting blade 10, the tooth plate 14 drives the gear 15 to rotate so that the rotating arm 18 pulls the extrusion plate 17 toward the baffle 16 to squeeze the debris.

[0024] The hydraulic valve core cutting device provided in this embodiment is used for cutting valve cores, particularly axial cutting of the outer surface. It automatically squeezes and discharges debris during the continuous cutting process, thereby improving the separation quality of debris and cutting fluid. This eliminates the need for workers to perform additional chip squeezing operations, thereby improving work efficiency. The terms related to directions and positions in this embodiment are relative to the accompanying drawings. A base 1 serves as the supporting body of the valve core cutting device. The base 1 has a drop-in port 101 at the top, a cutting fluid outlet 105 at the front, and a chip outlet 104 at the left. A third filter plate 102 for chip removal is removably mounted in the inner cavity of the base 1 via screws, dividing the inner cavity of the base 1 into an upper chamber and a lower chamber 103. The drop-in port 101 and the chip outlet 104 communicate with the upper chamber, while the lower chamber 103 communicates with the cutting fluid outlet 105. The lower chamber 103 is used to hold cutting fluid, which flows out through the cutting fluid outlet 105. The extruded debris is in the form of compressed blocks. When a certain amount of debris is accumulated, the debris receiving area opens, allowing the extruded debris to fall onto the third filter plate 102 and slide down along the third filter plate 102 toward the debris outlet 104, which is used to remove the extruded debris. A bracket 3 and a fixed platform 11 are fixedly mounted on the top of the base 1. A main shaft 4 is rotatably mounted on the bracket 3. A driven wheel 5 and a clamping mechanism 6 are coaxially fixedly mounted on the main shaft 4. The clamping mechanism 6 is used to clamp the valve core. The clamping mechanism 6 is preferably a three-jaw chuck, which is conventional and will not be described in detail. A first motor 2 is fixedly mounted on the base 1. A driving wheel 201 is coaxially fixedly mounted on the power output end of the first motor 2. The driving wheel 201 is connected to the driven wheel 5 via a transmission belt. By starting the first motor 2, the driving wheel 201 is driven to rotate. The driving wheel 201 drives the driven wheel 5 and the bracket 3 to rotate via the transmission belt. The bracket 3 drives the valve core to rotate at high speed to cut the valve core. The first motor 2, the driving wheel 201, the main shaft 4, the driven wheel 5, and the bracket 3 constitute a driving mechanism for driving the clamping mechanism 6 to rotate. The structure of the clamping mechanism 6 is prior art and will not be described in detail in this embodiment. Of course, the method by which the first motor 2 drives the clamping mechanism 6 to rotate is also prior art and will not be described in detail in this embodiment. The clamping mechanism 6 can also be driven to rotate by other transmission methods.Among them, an X-axis motion component and a Y-axis motion component are provided on the fixed platform 11, and the X-axis motion component includes a fixedly installed second motor 12, the second motor 12 is fixedly connected to the base 1 or the fixed platform 11, and the power output end of the second motor 12 is coaxially connected to the X-axis screw rod 1201 through a coupling (the threads on the X-axis screw rod 1201 and the Y-axis screw rod 1301 are not shown in the figure), and a first bearing seat 1102 is fixedly installed on the fixed platform 11 through a fixed connecting plate 1103. The end of the X-axis screw rod 1201 is rotatably plugged into the first bearing seat 1102, and the front end of the fixed platform 11 is fixedly installed The two lower guide rails 1101 are arranged relatively to each other at the rear, and the X-axis table 7 is slidably installed on the lower guide rails 1101 through two groups of lower sliders 702, wherein the bottom of the X-axis table 7 is fixedly connected to the two groups of lower sliders 702, and the two groups of lower sliders 702 are slidably engaged with the two lower guide rails 1101 in a one-to-one correspondence, and the first screw block 703 is screwed on the X-axis screw rod 1201, and the first screw block 703 is fixedly connected to the X-axis table 7. By starting the second motor 12 to drive the X-axis screw rod 1201 to rotate, the rotation of the X-axis screw rod 1201 drives the first screw block 703 and the X-axis table 7 to move along the axial direction of the X-axis screw rod 1201; The Y-axis motion assembly includes two groups of upper sliders 701 fixedly mounted on the top of the X-axis table 7, and an upper guide rail 801 is slidingly connected to the two groups of upper sliders 701 in a one-to-one corresponding manner. The top of the two upper guide rails 801 is fixedly mounted with a Y-axis table 8, and the top of the Y-axis table 8 is fixedly mounted with a tool holder 9 for fixing the cutting tool 10. The structure of the tool holder 9 is the existing technology and is not repeated here. A second screw block 802 is fixedly mounted on the bottom of the Y-axis table 8, and a third motor 13 is fixedly mounted on the X-axis table 7. The power output end of the third motor 13 is coaxially connected to a Y-axis screw rod 1301 through a coupling. The Y-axis screw rod 1301 and the second Screw block 802 is threadedly connected, and the end of Y-axis screw rod 1301 is rotatably plugged into a second bearing seat (not shown) fixedly mounted on X-axis stage 7. By activating third motor 13 to rotate Y-axis screw rod 1301, Y-axis screw rod 1301 drives second screw block 802 and Y-axis stage 8 to move axially along Y-axis screw rod 1301. Y-axis stage 8 then drives tool holder 9, to which cutting blade 10 is fixed, to move synchronously, thereby adjusting the position of cutting blade 10 in the Y-axis direction. The X-axis motion assembly drives X-axis stage 7 to move axially along X-axis screw rod 1201 to achieve X-axis motion of cutting blade 10. The X-axis direction is the axial direction of the valve core, and the Y-axis direction is perpendicular to the valve core axis.

[0025] In this embodiment, the tooth plate 14 is fixedly mounted on the bottom of the X-axis table 7 on the X-axis motion assembly. When the X-axis table 7 moves along the axial direction of the X-axis screw rod 1201, it drives the tooth plate 14 to move synchronously. The center rotation of the gear 15 is connected with a rotating shaft 1501. One end of the rotating shaft 1501 is rotatably connected or fixedly connected to the base 1. The tooth plate 14 is engaged with the gear 15. When the tooth plate 14 moves, it drives the gear 15 to rotate. The eccentric position of the gear 15 is fixedly installed with an eccentric shaft 1502. The extrusion plate 17 is slidably arranged in the base 1 along the axial direction of the valve core. A connecting shaft 1701 is fixedly installed or rotatably installed on the side of the extrusion plate 17. One end of the rotating arm 18 is rotatably connected to the eccentric shaft 1502, and the other end is rotatably connected to the connecting shaft 1701. When the X-axis stage 7 moves toward the valve core, the gear plate 14 is driven to drive the gear 15 to rotate clockwise. The clockwise rotation of the gear 15 drives the eccentric shaft 1502 to push the rotating arm 18. The rotating arm 18 pushes the extrusion plate 17 to slide away from the baffle 16, thereby enlarging the top opening of the debris receiving area and increasing the volume. Increase, the tooth plate 14 and the gear 15 are separated before the cutting blade 10 contacts the valve core. At this time, the tooth plate 14 will not drive the gear 15 to rotate, and the position of the extrusion plate 17 will not change. At this time, the top opening of the debris receiving area covers the entire valve core, so that the debris generated during cutting falls into the debris receiving area from the top opening of the debris receiving area, and because the tooth plate 14 and the gear 15 are separated before the cutting blade 10 contacts the valve core, the engagement between the tooth plate 14 and the gear 15 during the cutting operation will not affect the stable feed of the X-axis motion assembly, and thus will not affect the cutting quality. Similarly, when the cutting is completed, the X-axis table 7 moves in the direction away from the valve core to gradually reset the cutter 10. During the reset process of the cutter 10, when the cutter 10 is staggered from the valve core, the tooth plate 14 and the gear 15 are re-engaged, so that the tooth plate 14 and the gear 15 rotate counterclockwise. The counterclockwise rotation of the gear 15 drives the eccentric shaft 1502 to pull the rotating arm 18, and the rotating arm 18 then pulls the extrusion plate 17 close to the baffle 16, so that the volume of the debris receiving area is continuously reduced. When the amount of debris in the debris receiving area is large, the extrusion plate 17 is close to the baffle 16. During the process, the debris is continuously squeezed to compact the originally fluffy debris, thereby discharging the cutting fluid remaining in the debris, and the cutting fluid flows downward through the filter assembly. After passing through the filter assembly, the cutting fluid enters the upper chamber from the drop-in port 101, and then passes through the third filter plate 102 to enter the lower chamber 103 for collection; wherein, when the debris enters the debris receiving area, it falls on the filter assembly, and the bottom surface of the squeezing plate 17 abuts against the top surface of the filter assembly. In the process of the squeezing plate 17 moving toward the baffle 16, the squeezing plate 17 effectively pushes the debris falling on the filter assembly.

[0026] The principle is as follows: first, the X-axis motion assembly and the cutting blade 10 are in the initial position, at which time the cutting blade 10 is farthest from the clamping mechanism 6, then the valve core to be cut is fixedly installed on the clamping mechanism 6, and then the clamping mechanism 6 is driven to rotate by the driving mechanism, thereby driving the valve core to rotate, and then the X-axis motion assembly drives the cutting blade 10 to move toward the valve core, at this time the X-axis motion assembly drives the tooth plate 14 to drive the gear 15 to rotate, and the gear 15 pushes the extrusion plate 17 through the rotating arm 18 to slide away from the baffle 16 to make the top opening of the debris receiving area larger, and before the cutting blade 10 contacts the valve core, the tooth plate 14 and the gear 15 are separated, and at this time the top opening of the debris receiving area covers the entire valve core, and then the cutting blade 10 cuts the valve core, and the debris generated during cutting falls into the debris receiving area with the cutting fluid, and the cutting fluid falls through the filter assembly, while the debris continues to remain in the debris receiving area. After cutting is completed, the X-axis motion assembly drives the cutting knife 10 to move away from the valve core until it is reset. During this process, the X-axis motion assembly drives the gear plate 14 to drive the gear 15 to rotate so that the rotating arm 18 pulls the extrusion plate 17 toward the baffle 16 to squeeze the debris, so that the cutting fluid in the debris is squeezed out.

[0027] Thus, the present invention provides a debris receiving area and, during the cutting process, cleverly utilizes the X-axis motion assembly to drive the movement of the cutting blade 10, thereby causing the volume of the debris receiving area to increase and decrease. When the cutting blade 10 cuts the valve core, the volume of the debris receiving area increases and covers the entire valve core, so that debris generated during cutting and cutting fluid fall into the debris receiving area. The cutting fluid is filtered out by the filter assembly, and the debris remains in the debris receiving area. When the cutting is completed and the X-axis motion assembly drives the cutting blade 10 to return, the volume of the debris receiving area decreases, squeezing the debris remaining in the debris receiving area, thereby automatically squeezing out the cutting fluid remaining in the debris. Because the squeezing of the debris is automatically achieved throughout the entire process of cutting the valve core, the operator does not need to separately squeeze the fluffy debris again, thereby saving the operator's working time and energy. More cutting fluid is discharged from the debris, thereby improving the separation quality of the debris and cutting fluid and improving work efficiency.

[0028] Furthermore, a baffle shaft 1601 is rotatably plugged into the baffle 16, and both ends of the baffle shaft 1601 are fixedly connected to the base 1. The baffle 16 is elastically swingingly arranged in the base 1, and the baffle 16 rotates around the baffle shaft 1601. A limit plate 1602 is fixedly installed at the bottom of the baffle 16, and one end of the filter assembly is overlapped on the limit plate 1602. As the debris continues to enter the debris receiving area, the extrusion plate 17 squeezes the debris toward the baffle 16, driving the debris to push the baffle 16 to swing elastically around the baffle shaft 1601 to disengage the filter assembly from the limit plate 1602 and rotate downward to open the debris receiving area. After the debris receiving area is opened, the squeezed debris disengages from the debris receiving area and passes through the upper cavity and falls onto the third filter plate 102, and then slides along the third filter plate 102 to the debris outlet 104 for removal. It can be seen that the present invention can automatically open the debris receiving area after the debris is squeezed to a certain extent by setting the baffle 16 to rotate elastically, so as to realize automatic discharge of the extruded debris.

[0029] Specifically, the top surface of the limiting plate 1602 extends toward the extrusion plate 17. In the initial state, the baffle 16 is in a vertical state, and the bottom of one end of the filter assembly abuts against the top surface of the limiting plate 1602. At this time, the limiting plate 1602 plays a limiting role on the filter assembly, so that the filter assembly becomes the bottom plate of the debris receiving area, which is used to receive debris. At this time, the bottom surface of the extrusion plate 17 abuts against the top surface of the filter assembly, and when the extrusion plate 17 moves toward the baffle 16, the debris is squeezed. In the early stage of collecting debris, due to the small amount of debris, even if the volume of the debris receiving area reaches the minimum, the debris will not be squeezed, and the debris can only be pushed to one place for accumulation. As the debris continues to increase, the accumulation amount of the debris continues to increase. When the volume of the debris receiving area becomes smaller, the debris is squeezed, and as the amount of debris continues to increase, the squeezing force received by the debris also becomes greater. When the squeezing force received by the debris is greater than the elastic rotation resistance of the baffle 16, the debris squeezing baffle 16 elastically rotates to make the limit plate 1602 move away from the filter assembly until the end of the filter assembly is separated from the limit plate 1602. At this time, under the action of the gravity of the debris and the gravity of the filter assembly, the filter assembly rotates downward. At this time, the debris receiving area is opened, so that the squeezed debris falls onto the third filter plate 102. The squeezed debris is in a compacted block shape, so that it can slide down along the third filter plate 102 to the debris outlet 104.

[0030] Furthermore, the extrusion plate 17 includes a fixed pushing square rod 1703, and the filter assembly includes a rotatable main plate 20. A high plane 2001 is formed on the top of the end of the main plate 20 away from the baffle 16. During cutting, the extrusion plate 17 drives the pushing square rod 1703 to move toward the high plane 2001 until the bottom surface of the pushing square rod 1703 abuts against the top surface of the high plane 2001, thereby driving the pushing square rod 1703 to push the filter assembly to reset after rotating downward. Specifically, the front and rear sides of the main plate 20 are rotatably connected with a coaxial main plate shaft 2002, and the main plate shaft 2002 is fixedly connected or rotatably connected to the base 1. The main plate 20 rotates around the main plate shaft 2002, and the high plane 2001 protrudes upward from the top surface of the filter assembly. The number of high planes 2001 is two and they are arranged front to back. The number of pushing square rods 1703 is two and corresponds to the two high planes 2001 one by one. The main plate shaft 2002 is located above the pushing square rod 1703, so that the pushing square rod 1703 does not contact the main plate shaft 2002. When the filter assembly rotates downward to When the debris receiving area is opened, when cutting again, the extrusion plate 17 slides in the direction away from the baffle 16, so that the ends of the two extrusion plates 17 abut against the main plate 20 and push the main plate 20 to rotate around the main plate rotation axis 2002, driving the end of the filter assembly to abut against the side of the limit plate 1602 and push the limit plate 1602 to elastically rotate in the direction away from the main plate 20. When the bottom surfaces of the two extrusion plates 17 correspond one to one with the two high planes 2001, the end of the filter assembly passes over the limit plate 1602 and re-overlaps with the top surface of the limit plate 1602, so that the filter assembly is automatically reset.

[0031] The side surface of the limiting plate 1602 that contacts the filter assembly is an inclined surface. The inclined surface is designed so that when the filter assembly rotates upward, the limiting plate 1602 can be pushed to rotate by the inclined surface.

[0032] In this embodiment, the filter assembly rotates downward around the main plate rotation axis 2002 .

[0033] A fixed block 107 is fixedly installed within the base 1. A limit spring 19, which is a compression spring, is fixedly connected between the fixed block 107 and the limit plate 1602. Specifically, there are two fixed blocks 107, each fixedly installed on the front and rear inner walls of the base 1. A limit spring 19 is connected between each of the two fixed blocks 107 and the limit plate 1602. The elastic force of the limit spring 19 enables the elastic rotation of the baffle 16. In the initial state, the limit spring 19 is in a non-compressed state. When the filter assembly pushes the limit plate 1602 to rotate, the limit spring 19 is compressed and deformed. The fixed block 107 and the gear 15 are staggered front and back, and the rotating arm 18 and the rotating shaft 1501 are staggered front and back.

[0034] In this embodiment, there are two tooth plates 14 and two gears 15, which are meshed in a one-to-one correspondence. The two gears 15 are each rotatably mounted on the front and rear inner walls of the base 1 through a rotating shaft 1501. An eccentric shaft 1502 is provided at the eccentric position of the two gears 15. There are two rotating arms 18, which are rotatably connected to the two eccentric shafts 1502 in a one-to-one correspondence. The extrusion plate 17 is located between the two rotating arms 18. When the gear 15 rotates, the two rotating arms 18 are driven to synchronously push and pull the extrusion plate 17 to slide, thereby improving the force balance of the extrusion plate 17.

[0035] The sliding setting of the extrusion plate 17 is as follows: two groups of vertical guide rails 106 arranged symmetrically in the front and back are fixedly installed in the base 1, and the number of vertical guide rails 106 in each group of vertical guide rails 106 is two and arranged up and down. Two horizontal rods 1702 arranged up and down are inserted into the extrusion plate 17, and a vertical sliding block 17021 is installed at both ends of the two horizontal rods 1702. The four vertical sliding blocks 17021 are slidingly set in the four vertical guide rails 106 in a one-to-one manner. The connection position of the rotating arm 18 and the extrusion plate 17 is located between the two horizontal rods 1702, that is, the connecting shaft 1701 is located between the two horizontal rods 1702.

[0036] In this embodiment, the filter assembly also includes a push-pull mechanism fixedly installed in the main body plate 20 and a first filter plate 21 elastically slidably arranged on the push-pull mechanism. The push-pull mechanism is located below the first filter plate 21 and abuts against the bottom of the first filter plate 21. During the process of the filter assembly disengaging from the limit plate 1602 and rotating downward, the first filter plate 21 is driven to elastically slide above the push-pull mechanism to vibrate the first filter plate 21. The vibration of the first filter plate 21 allows the fine debris remaining on the first filter plate 21 to be more smoothly separated from the first filter plate 21, thereby achieving the cleaning effect of the debris remaining on the first filter plate 21. Specifically, the top surface of the first filter plate 21 and the top surface of the main plate 20 are located on the same horizontal plane. The top surface of the first filter plate 21 and the top surface of the main plate 20 together constitute the top surface of the filter assembly. The debris and cutting fluid generated during cutting fall on the top surface of the first filter plate 21, and the cutting fluid flows downward through the several first filter holes 2101 opened on the first filter plate 21. When the extrusion plate 17 slides toward the baffle 16, the extrusion plate 17 pushes the debris to the top surface of the main plate 20, so that the debris will not be stuck in the first filter holes 2101 during the subsequent extrusion process, thereby facilitating the discharge of the debris. Among them, the front and rear sides of the first filter plate 21 are fixedly installed with side guide plates 2102, and the push-pull mechanism is provided with two side guide grooves 2301 which are slidably plugged in one by one with the two side guide plates 2102. The end of the first filter plate 21 is fixedly installed with an end plate 22, and a flat compression spring 26 is connected between the end plate 22 and the push-pull mechanism. A mounting seat 27 is fixedly installed in the base 1, and a top rod 2701 is fixedly installed on the mounting seat 27, which is in contact with the side of the end plate 22 away from the first filter plate 21. In the initial state, the filter assembly is overlapped with the limit plate 1602. At this time, the top rod 2701 abuts against the side of the end plate 22, the end of the first filter plate 21 abuts against the side of the main plate 20, and the flat compression spring 26 is fixedly installed in the base 1. 6 is in a compressed state. When the filter assembly is separated from the limit plate 1602 and rotates downward around the main plate rotation axis 2002 under the action of its own gravity and the gravity of the debris, the main plate 20, the push-pull mechanism, the first filter plate 21 and the end plate 22 rotate downward synchronously. The rotation of the end plate 22 causes the end plate 22 to move away from the top rod 2701, so that the elastic force of the flat compression spring 26 is released to push the end plate 22 and the first filter plate 21 to slide relative to the push-pull mechanism. Since the push-pull mechanism abuts against the bottom surface of the first filter plate 21, the push-pull mechanism drives the first filter plate 21 to vibrate when it slides, and the vibration force is used to make the fine debris remaining on the first filter plate 21 fall along the first filter plate 21.

[0037] The push-pull mechanism is provided with a leak 2403. When the push-pull mechanism slides, the leak 2403 is offset from the side of the first filter plate 21, allowing fine debris falling from the first filter plate 21 to pass through the leak 2403 and fall into the upper cavity of the base 1. Similarly, when the filter assembly is pushed upward and reset by the pushing square rod 1703, the side of the end plate 22 re-engages with the push rod 2701. The blocking action of the push rod 2701 causes the end plate 22 to compress and lay flat against the compression spring 26 until the filter assembly is reset. There are at least two push rods 2701, and the push rods 2701 are staggered front and back relative to the pushing square rod 1703.

[0038] In this embodiment, the push-pull mechanism includes a box body 23 fixedly connected to the main plate 20, the first filter plate 21 is slidably engaged with the box body 23, and a second filter plate 24 is elastically slidably provided in the box body 23 to abut against the bottom of the first filter plate 21. Specifically, two side guide grooves 2301 are correspondingly formed on the front and rear inner walls of the box body 23. The box body 23 is provided with a plurality of 2302, and the second filter plate 24 is provided with a plurality of second filter holes 2401. The first filter holes 2101, 2302, and second filter holes 2401 are used to pass cutting fluid. A plurality of vertical compression springs 25 are fixedly mounted within the box body 23. The top of the vertical compression springs 25 is fixedly connected to the bottom of the second filter plate 24. The left and right side surfaces, as well as the front and rear side surfaces, of the second filter plate 24 slide against the inner wall of the box body 23 to achieve a sliding connection between the second filter plate 24 and the box body 23. Due to the position restriction of the inner wall of the box body 23, the second filter plate 24 cannot move horizontally and can only slide up and down. Under the compressive force of the vertical compression springs 25, the second filter plate 24 elastically abuts against the bottom of the first filter plate 21. A leak 2403 extends through the second filter plate 24 and the box body 23.

[0039] A strip plate 2404 is fixedly installed on the top of the second filter plate 24 , and there are one or more flat compression springs 26 , one end of the flat compression spring 26 is fixedly connected to the strip plate 2404 , and the other end is fixedly connected to the end plate 22 .

[0040] Furthermore, the first filter plate 21 includes a plurality of trapezoidal plates 2103 fixedly mounted on its bottom, and the second filter plate 24 includes a plurality of hemispherical bodies 2402 fixedly mounted on its top. The tops of the plurality of hemispherical bodies 2402 are elastically in contact with the bottom of the first filter plate 21. The pushing force generated by the flat compression spring 26 on the first filter plate 21 is greater than the resistance of the hemispherical body 2402 when it passes over the trapezoidal plate 2103. When the elastic force of the flat compression spring 26 drives the first filter plate 21 to slide elastically above the push-pull mechanism, the hemispherical body 2402 elastically passes over the trapezoidal plate 2103 and hits the bottom of the first filter plate 21. Several hemispheres 2402 are arranged in a rectangular array so that the hemispheres 2402 form multiple vertical columns, and multiple trapezoidal plates 2103 are arranged horizontally. The hemispheres 2402 in the multiple vertical columns correspond to the multiple trapezoidal plates 2103 one by one, and the hemispheres 2402 in each vertical column are at the same distance from the corresponding trapezoidal plates 2103, so that the hemispheres 2402 in the multiple vertical columns pass over the corresponding trapezoidal plates 2103 at the same time. By utilizing the elastic force of the upright compression spring 25, when the hemispheres 2402 pass over the corresponding trapezoidal plates 2103, the hemispheres 2402 are driven to elastically hit the bottom of the first filter plate 21 to enhance the vibration force of the first filter plate 21.

[0041] The extrusion plate 17 is provided with an escape opening 1704 running through the bottom thereof. The top surface of the escape opening 1704 is the bottom surface of the extrusion plate 17 , and the top surface of the escape opening 1704 abuts against the top surface of the first filter plate 21 and the top surface of the main plate 20 .

[0042] Two limit plates are fixedly installed on the baffle shaft and the main plate shaft. The baffle shaft is located between the corresponding two limit plates, and the main plate shaft is located between the corresponding two limit plates. The limit plates are used to axially limit the baffle shaft and the main plate shaft.

[0043] In this embodiment, a blocking component can be selectively fixed in the base 1 to abut against the filter assembly when it rotates downward. The blocking component is not limited to any shape as long as it can block the filter assembly. When the filter assembly rotates downward to a specific angle, it abuts against the blocking component. The specific angle is any angle that can allow debris to slide downward from the debris receiving area.

[0044] The top surface of the main body plate 20 is seamlessly connected to the high plane 2001 through an inclined surface, so that the pushing square rod 1703 can be smoothly pushed onto the high plane 2001 when pushing the filter assembly.

[0045] Second embodiment: A hydraulic valve core cutting process, the structure of which can be referred to as a hydraulic valve core cutting device, includes the following steps: S1: Installation: First, the X-axis motion assembly and the cutting blade 10 are in the initial position. At this time, the cutting blade 10 is farthest from the clamping mechanism 6. Then, the valve core to be cut is fixedly installed on the clamping mechanism 6. S2: Chip cutting: The clamping mechanism 6 is driven to rotate by the driving mechanism, thereby driving the valve core to rotate. Then, the X-axis motion assembly drives the cutting blade 10 to move toward the valve core. At this time, the X-axis motion assembly drives the tooth plate 14 to drive the gear 15 to rotate. The gear 15 pushes the extrusion plate 17 to slide away from the baffle 16 through the rotating arm 18 to enlarge the top opening of the chip receiving area. Before the cutting blade 10 contacts the valve core, the tooth plate 14 and the gear 15 separate. At this time, the top opening of the chip receiving area covers the entire valve core. Then, the cutting blade 10 cuts the valve core. The chips generated during cutting fall into the chip receiving area together with the cutting fluid. The cutting fluid falls through the filter assembly, while the chips continue to remain in the chip receiving area. S3: Extruding the chips: After cutting is completed, the X-axis motion assembly drives the cutting blade 10 to move away from the valve core until it is reset. During this process, the X-axis motion assembly drives the gear plate 14 to drive the gear 15 to rotate so that the rotating arm 18 pulls the extrusion plate 17 toward the baffle 16 to squeeze the chips, so that the cutting fluid in the chips is squeezed out.

[0046] In step S3, a baffle shaft 1601 is rotatably plugged into the baffle 16, and both ends of the baffle shaft 1601 are fixedly connected to the base 1. The baffle 16 is elastically swingingly arranged in the base 1, and the baffle 16 rotates around the baffle shaft 1601. A limit plate 1602 is fixedly installed at the bottom of the baffle 16, and one end of the filter assembly is overlapped on the limit plate 1602. As the debris continues to enter the debris receiving area, the extrusion plate 17 squeezes the debris toward the baffle 16, driving the debris to push the baffle 16 to swing elastically around the baffle shaft 1601 to disengage the filter assembly from the limit plate 1602 and rotate downward to open the debris receiving area. After the debris receiving area is opened, the squeezed debris disengages from the debris receiving area and passes through the upper cavity and falls onto the third filter plate 102. It then slides along the third filter plate 102 to the debris outlet 104 for removal. It can be seen that the present invention can automatically open the debris receiving area after the debris is squeezed to a certain extent by setting the baffle 16 to rotate elastically, so as to realize automatic discharge of the extruded debris.

[0047] The extrusion plate 17 includes a fixed pushing square rod 1703, and the filter assembly includes a rotatable main plate 20. A high plane 2001 is formed on the top of the end of the main plate 20 away from the baffle 16. During cutting, the extrusion plate 17 drives the pushing square rod 1703 to move toward the high plane 2001 until the bottom surface of the pushing square rod 1703 abuts against the top surface of the high plane 2001, thereby driving the pushing square rod 1703 to push the filter assembly to reset after rotating downward. Specifically, the front and rear sides of the main plate 20 are rotatably connected with a coaxial main plate shaft 2002, and the main plate shaft 2002 is fixedly connected or rotatably connected to the base 1. The main plate 20 rotates around the main plate shaft 2002, and the high plane 2001 protrudes upward from the top surface of the filter assembly. The number of high planes 2001 is two and they are arranged front to back. The number of pushing square rods 1703 is two and corresponds to the two high planes 2001 one by one. The main plate shaft 2002 is located above the pushing square rod 1703, so that the pushing square rod 1703 does not contact the main plate shaft 2002. When the filter assembly rotates downward to When the debris receiving area is opened, when cutting again, the extrusion plate 17 slides in the direction away from the baffle 16, so that the ends of the two extrusion plates 17 abut against the main plate 20 and push the main plate 20 to rotate around the main plate rotation axis 2002, driving the end of the filter assembly to abut against the side of the limit plate 1602 and push the limit plate 1602 to elastically rotate in the direction away from the main plate 20. When the bottom surfaces of the two extrusion plates 17 correspond one to one with the two high planes 2001, the end of the filter assembly passes over the limit plate 1602 and re-overlaps with the top surface of the limit plate 1602, so that the filter assembly is automatically reset.

[0048] In step S2, the filter assembly further includes a push-pull mechanism fixedly mounted in the main plate 20 and a first filter plate 21 elastically slidably mounted on the push-pull mechanism. The push-pull mechanism is located below the first filter plate 21 and abuts against the bottom of the first filter plate 21. During the process of the filter assembly disengaging from the limit plate 1602 and rotating downward, the first filter plate 21 is driven to elastically slide above the push-pull mechanism to vibrate the first filter plate 21. The vibration of the first filter plate 21 allows fine debris remaining on the first filter plate 21 to be more smoothly separated from the first filter plate 21, thereby achieving the cleaning effect of the debris remaining on the first filter plate 21. The push-pull mechanism is provided with a leakage port 2403. When the push-pull mechanism slides, the leakage port 2403 is offset from the side of the first filter plate 21, so that fine debris falling from the first filter plate 21 passes through the leakage port 2403 and falls into the upper cavity in the base 1. Similarly, when the filter assembly is pushed upward and reset by the pushing square rod 1703, the side of the end plate 22 re-engages the push rod 2701, and the blocking action of the push rod 2701 causes the end plate 22 to compress and lay flat against the compression spring 26 until the filter assembly is reset. There are at least two push rods 2701, and the push rods 2701 are staggered front and back with respect to the pushing square rod 1703.

[0049] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
