Description

Technical Field

[0001] This invention belongs to the field of intelligent manufacturing grinding devices, specifically relating to a grinding device for processing intelligent manufacturing hydraulic cylinders. Background Technology

[0002] During the machining stage, the inner circle of the hydraulic cylinder needs to be ground. The grinding wheel is moved back and forth on the inner circle to perform thorough grinding. During the grinding process, grinding fluid needs to be sprayed to cool and lubricate the grinding wheel.

[0003] Patent publication number CN108942439B relates to a roller-type internal grinding machine, comprising a base plate, a mounting seat, a clamping mechanism, a drive mechanism, and a processing assembly. The mounting seat is fixed to the base plate. The clamping mechanism includes fixed clamping members, movable clamping members, and a top clamping member distributed around the workpiece for clamping it, and a centering shaft located at one end of the workpiece for top clamping it. The fixed clamping member and the movable clamping member are respectively provided with a first pulley and a second pulley. The drive mechanism is connected to the first and second pulleys via a belt. The processing assembly is located on the side of the workpiece to be processed. This roller-type internal grinding machine is easy to clamp, requires no manual clamping, has high production efficiency, and does not rely on the operator's experience, ensuring the machining accuracy and concentricity of the workpiece.

[0004] In the aforementioned patent, the roller-type internal grinding machine is easy to clamp, does not require manual clamping, has high production efficiency, and does not rely on the operator's work experience, ensuring the machining accuracy and concentricity of the workpiece. However, in the process of grinding the inner circle, in order to ensure the grinding effect, it is necessary to grind repeatedly and thoroughly in different areas, and to spray grinding fluid to ensure the cooling and lubrication effect of the grinding wheel. The aforementioned patent makes it difficult to spray grinding fluid accurately in real time according to the current grinding position. Moreover, if the fixed spray pipe of the prior art is used, the grinding wheel is prone to adhering grinding fluid containing impurities during the grinding process. Furthermore, the used grinding fluid containing impurities is difficult to flow out in time, and the flow direction is difficult to control. It will remain in the grinding area and continue to adhere to the grinding wheel, leaving grinding impurities on the grinding wheel, which can easily lead to excessive wear on the workpiece surface and affect the grinding effect. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a grinding device for intelligent manufacturing hydraulic cylinder processing, which can accurately spray grinding fluid onto the grinding area in conjunction with the frequent movement of the grinding wheel, ensuring that the grinding wheel is in constant contact with clean grinding fluid free of impurities.

[0006] A grinding device for machining hydraulic cylinders according to an embodiment of the present invention includes: a base and a slide rail. The slide rail is disposed on the surface of the base, and a feed mechanism is slidably mounted on the surface of the slide rail. The feed mechanism slides on the slide rail, and a motor is mounted on the surface of the feed mechanism. A grinding head is mounted on the output end of the motor. The movement of the feed mechanism drives the grinding head to move to the grinding area. Hydraulic clamps are disposed on both sides of the base to fix the workpiece. A spray pipe is disposed on the surface of the base, and an external spray system is connected to the spray pipe to deliver grinding fluid. The spray nozzle is connected to the grinding head. As the grinding head moves, the nozzle can precisely spray grinding fluid onto the grinding area where the grinding head is located. The surface of the grinding head has grooves. A protective frame mechanism is provided on the surface of the base near the spray nozzle. The protective frame mechanism includes an outer frame and an inner frame. The outer frame is installed on the surface of the base, and the inner frame is slidably installed on the inner wall of the outer frame. The spray nozzle is covered by the outer frame and the inner frame. Several flow grooves are provided at the edge of the grinding head surface so that the grinding fluid can flow to the other side of the grinding head in time after participating in the grinding.

[0007] In some embodiments of the present invention, the spray pipe is connected to an external spraying system. The spray pipe is located inside an outer frame and an inner frame. The outer frame and the inner frame control the deformation of the spray pipe within a certain range to prevent the spray pipe from being squeezed and deformed by the movement of the grinding head and impacting the inner wall of the workpiece. A nozzle is installed at the right end of the inner frame. The nozzle is connected to the spray pipe. A fixing frame is rotatably installed on the surface of the grinding head. Clips are provided on both sides of the fixing frame. The clips are used to connect the nozzle to the fixing frame to complete the docking of the nozzle and the grinding head.

[0008] In some embodiments of the present invention, a push rod is slidably mounted on the surface of the inner frame, and a first spring is provided between the push rod and the inner frame. The elastic force of the first spring drives the push rod to reset. A friction plate is slidably mounted on the surface of the push rod. When the inner frame moves, it drives the friction plate to move. The surface of the friction plate is in contact with the inner wall of the outer frame. When the friction plate moves, friction is generated between it and the inner wall of the outer frame. A support spring is provided between the friction plate and the push rod. The elastic force of the support spring ensures that the friction plate is in close contact with the inner wall of the outer frame to generate friction. A baffle is installed in the slot. The friction force pushes the friction plate to move outward, thereby pushing the push rod to move. A slip ring is slidably mounted in the slot near the baffle. After the push rod moves, it pushes the slip ring. After the slip ring moves, it is in contact with the baffle. A second spring is provided between the slip ring and the grinding head. The elastic force of the second spring causes the slip ring to reset.

[0009] In some embodiments of the present invention, a rack is mounted on the surface of the inner frame, which moves the rack during the movement of the inner frame. A gear is rotatably mounted on the surface of the outer frame, which meshes with the rack. When the rack moves, it drives the gear to rotate. A gear ring is rotatably mounted on the surface of the outer frame, which meshes with the gear. When the gear rotates, it drives the gear ring to rotate. A rotating ring is rotatably mounted on the surface of the inner frame, and a sleeve rod is mounted on the surface of the rotating ring. The rotating ring is sleeved with the gear ring through the sleeve rod. When the gear ring rotates, it drives the rotating ring to rotate by pushing the sleeve rod. Several triangular blocks are mounted on the surface of the rotating ring, which rotates when the rotating ring rotates. A push ring is slidably mounted on the surface of the inner frame, and a protruding rod is mounted on the surface of the push ring. The inclined surfaces of the triangular blocks frequently press against the protruding rod, pushing the push ring to move back and forth. A sliding rod is slidably mounted on the surface of the grinding head, and a left push plate is slidably mounted on the left end of the sliding rod. A rotating rod is sleeved on the surface of the push ring, and a locking rod is rotatably mounted on the surface of the rotating rod. The locking rod is sleeved on the surface of the sliding rod to complete the connection between the sliding rod and the push ring.

[0010] In some embodiments of the present invention, a right push plate is slidably mounted on the right end of the slide rod, and elastic elements are provided between the left and right push plates and the slide rod. The slide rod drives the left and right push plates to reciprocate left and right through the supporting force of the elastic elements. A folding rod is slidably mounted on the surface of the grinding head, and a stop rod is mounted on the surface of the slip ring. An inclined surface is provided on the surface of the folding rod near the stop rod. Limiting rods are installed at both ends of the folding rod. Circular holes are opened on the surfaces of the left and right push plates. By changing the position of the slip ring, the contact between the stop rod and the inclined surface of the folding rod is changed, thereby controlling the lifting or lowering of the folding rod and adjusting the limiting situation of the left and right push plates.

[0011] In some embodiments of the present invention, the left push plate and the right push plate are respectively located below the left side and above the right side of the grinding head. The left push plate and the right push plate are staggered so that they will not be blocked by each other when pushing the grinding fluid during their respective operations. A third spring is provided between the push ring and the inner frame. The elastic force of the third spring causes the push ring to return to its original position. A first torsion spring is provided between the clamping rod and the rotating rod. The elastic force of the first torsion spring supports the clamping rod and applies a pushing force to the clamping rod in the direction of the sliding rod to ensure that the clamping rod is tightly attached to the surface of the sliding rod. A return spring is provided between the bending rod and the grinding head. The elastic force of the return spring causes the bending rod to return to its original position.

[0012] In some embodiments of the present invention, push bars are installed on the upper and lower sides of the inner wall of the inner frame. The push bars are moved by the movement of the inner frame. Several rollers are rotatably installed on the surface of the push bars. The movement of the push bars drives the rollers to move. The upper and lower sides of the inner wall of the left end of the outer frame are rotatably installed with rocker arms. The rollers frequently squeeze the rocker arms and then pass over them. An arc plate is provided at the bottom of the rocker arm. The rocker arm rotates after being squeezed, causing the arc plate to deflect and contact the surface of the spray pipe. The movement of the arc plate pushes the spray pipe and transports the spray pipe to an open direction outside the outer frame.

[0013] In some embodiments of the present invention, a rotating block is rotatably mounted at the bottom of the rocker arm, the arc plate is slidably mounted at the bottom of the rotating block, a stop bar is mounted on the surface of the arc plate, and an arc strip is mounted on the surface of the rocker arm. The arc surface of the arc strip presses against the stop bar, causing the arc plate to lift up and release force. A second torsion spring is provided between the rocker arm and the outer frame. The supporting force of the second torsion spring causes the rocker arm to be in an inclined state and to return to its original position after rotation. A fourth spring is provided between the arc plate and the rotating block. The elastic force of the fourth spring causes the arc plate to lift up and then return to its original position.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a nozzle that follows the movement of the grinding head to precisely spray grinding fluid onto each grinding area according to the change in the grinding position of the grinding head. Each grinding area can come into contact with fresh grinding fluid, avoiding impurities that reduce grinding efficiency. No matter which direction the grinding head moves, the nozzle can change the direction of liquid discharge according to the direction of the grinding head's movement, spraying the grinding fluid in advance onto the area that the grinding head is about to grind, so that each grinding area can come into contact with fresh, impurity-free grinding fluid, ensuring the grinding effect.

[0015] 2. This invention, by creating a flow groove on the surface of the grinding head, allows the grinding fluid to flow promptly to the other side of the grinding head after participating in grinding, avoiding accumulation on the grinding head's travel path and affecting the grinding of the remaining area. By setting a left pusher plate and a right pusher plate, a thrust is applied to the grinding fluid containing impurities to promote flow. Regardless of which direction the grinding head is grinding, only one of the left and right pusher plates is always in a reciprocating state, pushing the used grinding fluid to the other side of the grinding area of ​​the grinding head. When the grinding head moves to the left, it pushes the grinding fluid to the right, and when the grinding head moves to the right, it pushes the grinding fluid to the left, away from the area to be ground.

[0016] 3. In this invention, the slurry pipe is enclosed by an outer frame and an inner frame. The outer frame and the inner frame control the deformation of the slurry pipe within a certain range, preventing the slurry pipe from being squeezed and deformed by the movement of the grinding head and impacting the inner wall of the workpiece. This ensures that sufficient space is left for the grinding head to grind the workpiece. At the same time, the relative movement of the inner frame and the outer frame drives the arc plate to move and push the slurry pipe, conveying the slurry pipe to an open direction outside the outer frame. This prevents the slurry pipe from being squeezed, bent, or folded by the grinding head, which would affect the flow rate of the grinding fluid. This ensures that the grinding fluid is sprayed out stably and that the grinding work is carried out continuously and stably. Attached Figure Description

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 - Figure 14As shown, one embodiment of the present invention is: a grinding device for intelligent manufacturing hydraulic cylinder processing, comprising: a base 1 and a slide rail 2, the slide rail 2 being disposed on the surface of the base 1, a feed mechanism 3 being slidably mounted on the surface of the slide rail 2, the feed mechanism 3 sliding on the slide rail 2, a motor 4 being mounted on the surface of the feed mechanism 3, a grinding head 5 being mounted on the output end of the motor 4, the feed mechanism 3 moving to drive the grinding head 5 to the grinding area, hydraulic clamps 6 being disposed on both sides of the base 1, the hydraulic clamps 6 fixing the workpiece, a spray pipe 7 being disposed on the surface of the base 1, an external spraying system spraying grinding fluid from a nozzle 10 through the spray pipe 7, the spray pipe 7 Connected to the grinding head 5, as the grinding head 5 moves, the nozzle 10 can precisely spray grinding fluid onto the grinding area where the grinding head 5 is located. The surface of the grinding head 5 has a groove 13. The surface of the base 1 is provided with a protective frame mechanism near the spray pipe 7. The protective frame mechanism includes an outer frame 8 and an inner frame 9. The outer frame 8 is installed on the surface of the base 1, and the inner frame 9 is slidably installed on the inner wall of the outer frame 8. The spray pipe 7 is covered by the outer frame 8 and the inner frame 9. Several flow grooves are provided at the edge of the surface of the grinding head 5 so that the grinding fluid can flow to the other side of the grinding head 5 in time after participating in the grinding, avoiding accumulation on the path of the grinding head 5 and affecting the grinding of the remaining area by the grinding head 5.

[0021] The spray pipe 7 is connected to an external spray system. The spray pipe 7 is located inside the outer frame 8 and the inner frame 9. The outer frame 8 and the inner frame 9 control the deformation of the spray pipe 7 within a certain range to prevent the spray pipe 7 from being squeezed and deformed by the movement of the grinding head 5 and impacting the inner wall of the workpiece. This ensures that there is enough space for the grinding head 5 to grind the workpiece. A nozzle 10 is installed on the right end of the inner frame 9. The nozzle 10 is connected to the spray pipe 7. A fixed frame 11 is rotatably installed on the surface of the grinding head 5. Clips 12 are set on both sides of the fixed frame 11. The clips 12 are used to connect the nozzle 10 to the fixed frame 11, completing the docking of the nozzle 10 and the grinding head 5. This ensures that the nozzle 10 moves linearly under the push of the grinding head 5 and stably sprays the grinding area.

[0022] A push rod 16 is slidably mounted on the surface of the inner frame 9. A first spring is provided between the push rod 16 and the inner frame 9. The elastic force of the first spring drives the push rod 16 to return to its original position. A friction plate 17 is slidably mounted on the surface of the push rod 16. When the inner frame 9 moves, it also drives the friction plate 17 to move. The surface of the friction plate 17 is in contact with the inner wall of the outer frame 8. Friction is generated between the friction plate 17 and the inner wall of the outer frame 8 when the friction plate 17 moves. A support spring 18 is provided between the friction plate 17 and the push rod 16. The elastic force of the support spring 18 ensures that the friction plate 17 is in close contact with the inner wall of the outer frame 8 to generate friction. A baffle 14 is installed in the slot 13. The friction force pushes the friction plate 17 to move outward, thereby pushing... The push rod 16 moves, and a slip ring 15 is slidably installed in the slot 13 near the baffle 14. After the push rod 16 moves, it pushes the slip ring 15. After the slip ring 15 moves, it fits against the baffle 14. The contact state between the slip ring 15 and the baffle 14 is adjusted by the extension and retraction of the push rod 16, which changes the direction of the grinding fluid flow at the nozzle 10. No matter what direction the grinding head 5 moves, the nozzle 10 can spray the grinding fluid in advance onto the area that the grinding head 5 is about to grind, so that each grinding area can come into contact with fresh grinding fluid without impurities, ensuring the grinding effect. A second spring is provided between the slip ring 15 and the grinding head 5. The elastic force of the second spring makes the slip ring 15 return to its original position.

[0023] In this embodiment, during operation: the workpiece to be ground is clamped and fixed by the hydraulic clamp 6, and the workpiece covers the inner frame 9, so that the inner frame 9 is located in the inner circle of the workpiece. The nozzle 10 is connected to the grinding head 5, and the clamp 12 is used to connect the nozzle 10 to the fixed frame 11, completing the connection between the nozzle 10 and the grinding head 5. The equipment is started, and the feeding mechanism 3 and the motor 4 start working. The output end of the motor 4 drives the grinding head 5 to rotate. With the reciprocating movement of the feeding mechanism 3, the grinding head 5 drives the grinding head 5 to grind the inner wall of the workpiece in the inner circle. While the feeding mechanism 3 drives the grinding head 5 to reciprocate, the nozzle 10 moves with the grinding head 5. The external spraying system sprays grinding fluid from the nozzle 10 through the connecting spray pipe 7. As the grinding head 5 moves, the nozzle 10 can accurately spray grinding fluid onto the grinding area where the grinding head 5 is located. In the prior art, grinding fluid spraying devices... Typically, the position is fixed, and only the outlet angle can be slightly changed. Because the grinding wheel needs to reciprocate within the inner circle of the workpiece during grinding, the grinding area and range of the grinding wheel change in real time. Existing spray devices cannot adjust the grinding fluid spray range in real time according to the changes in the grinding area. During the movement of the grinding wheel, the grinding fluid used in the previous grinding area will be carried into the new grinding area, causing the grinding fluid that has already participated in grinding to flow to the next grinding area after containing grinding impurities. When grinding impurities are between the grinding wheel and the inner wall of the workpiece, they affect the contact between the grinding wheel and the workpiece, causing unnecessary losses and affecting the smoothness of grinding. By having the nozzle 10 follow the movement of the grinding head 5, the grinding fluid can be precisely sprayed onto each grinding area according to the change in the grinding position of the grinding head 5. Each grinding area can come into contact with new grinding fluid, avoiding the introduction of impurities and reducing grinding efficiency.

[0024] Several flow grooves are opened at the edge of the grinding head 5 so that the grinding fluid can flow to the other side of the grinding head 5 in time after participating in the grinding, avoiding the accumulation on the travel path of the grinding head 5 and affecting the grinding of the remaining area. The spray pipe 7 is covered by the outer frame 8 and the inner frame 9. The outer frame 8 and the inner frame 9 control the deformation of the spray pipe 7 within a certain range, preventing the spray pipe 7 from being squeezed and deformed by the movement of the grinding head 5 and impacting the inner wall of the workpiece, ensuring that there is enough space for the grinding head 5 to grind the workpiece. The outer frame 8 and the inner frame 9 provide support for the nozzle 10. The fixing frame 11 connects the nozzle 10 to the grinding head 5. When the grinding head 5 rotates, it will not drive the nozzle 10 to rotate, ensuring that the nozzle 10 moves linearly under the push of the grinding head 5 and sprays the grinding area stably. When the grinding head 5 drives the nozzle 10 to move back and forth, it pushes and pulls the inner frame 9 back and forth. When the grinding head 5 feeds from right to left, it pushes the inner frame 9 to move inward into the outer frame 8. The movement of the inner frame 9 simultaneously drives the friction plate 17 to move. When the friction plate 17 moves, it generates friction with the inner wall of the outer frame 8. Through friction, the friction plate 17 moves outward, thereby pushing the push rod 16 to move. After the push rod 16 moves, it pushes the slip ring 15. After the slip ring 15 moves, it comes into contact with the baffle 14 and together with the baffle 14, they form a barrier to block the flow of grinding fluid sprayed from the nozzle 10, causing the grinding fluid to flow out from the left side of the grinding head 5. Because the grinding head 5 is moving from right to left at this time, the grinding fluid drips out from the left side of the grinding head 5, causing the grinding area that the grinding head 5 is about to contact to adhere in advance. When the grinding head 5 completes one grinding cycle from right to left on the workpiece, it begins to move in the opposite direction, grinding the workpiece from left to right. At this time, the grinding head 5 pulls the inner frame 9 out of the outer frame 8, and the direction of the friction force between the outer frame 8 and the friction plate 17 reverses. It no longer applies a pushing force to the push rod 16 and pulls the push rod 16 back. The push rod 16 no longer pushes the slip ring 15. The slip ring 15 resets under the elastic force, adheres to the surface of the nozzle 10, and opens the gap between it and the baffle 14. Because the slip ring 15 is now in contact with the nozzle 10, it forms a blockage from the left side of the nozzle 10. At this time, the grinding fluid at the nozzle 10 can only flow out from the right side of the grinding head 5 through the gap between the slip ring 15 and the baffle 14, and spray the grinding area behind it in advance along the reset path of the grinding head 5. Regardless of the direction of movement of the grinding head 5, the nozzle 10 can spray the grinding fluid in advance onto the area of ​​the grinding head 5 that is about to be ground, so that each grinding area can come into contact with fresh grinding fluid without impurities, thus ensuring the grinding effect.

[0025] Please see Figure 1 - Figure 14In another embodiment of the present invention, based on the above embodiments, a rack 19 is mounted on the surface of the inner frame 9, and the rack 19 moves during the movement of the inner frame 9. A gear 20 is rotatably mounted on the surface of the outer frame 8, and the gear 20 meshes with the rack 19. When the rack 19 moves, it pushes the gear 20 to rotate. A gear ring 21 is rotatably mounted on the surface of the outer frame 8, and the gear ring 21 meshes with the gear 20. After the gear 20 rotates, it pushes the gear ring 21 to rotate. A rotating ring 22 is rotatably mounted on the surface of the inner frame 9, and a sleeve rod 26 is mounted on the surface of the rotating ring 22. The rotating ring 22 passes through the gear ring 21 and is sleeved with the gear ring 21 through the sleeve rod 26. When the gear ring 21 rotates, it pushes the sleeve rod 26 to drive the rotating ring 22 to rotate. A gear ring 22 is mounted on the surface of the rotating ring 22. Several triangular blocks 23 are rotated when the rotating ring 22 rotates. A push ring 25 is slidably installed on the surface of the inner frame 9. A protruding rod 24 is installed on the surface of the push ring 25. The inclined surface of the triangular block 23 frequently presses against the protruding rod 24, pushing the push ring 25 to move back and forth. A slide rod 29 is slidably installed on the surface of the grinding head 5. A left push plate 30 is slidably installed on the left end of the slide rod 29. A rotating rod 28 is sleeved on the surface of the push ring 25. A locking rod 27 is rotatably installed on the surface of the rotating rod 28. The locking rod 27 is sleeved on the surface of the slide rod 29 to complete the docking of the slide rod 29 and the push ring 25. When the push ring 25 moves, it drives the slide rod 29 to move left and right, which drives the left push plate 30 to move and push away the grinding fluid used during grinding when the grinding head 5 moves to the left.

[0026] A right push plate 31 is slidably mounted on the right end of the slide rod 29. Elastic elements are provided between the left push plate 30 and the right push plate 31 and the slide rod 29. The slide rod 29 drives the left push plate 30 and the right push plate 31 to move back and forth through the supporting force of the elastic elements. A folding rod 32 is slidably mounted on the surface of the grinding head 5. A stop rod 34 is mounted on the surface of the slip ring 15. An inclined surface is provided on the surface of the folding rod 32 near the stop rod 34. Limit rods 33 are installed at both ends of the folding rod 32. Circular holes are opened on the surfaces of the left push plate 30 and the right push plate 31, allowing the slip ring 15 to pass through. The positional change of the contact between the abutment 34 and the inclined surface of the bending rod 32 controls the upward or downward movement of the bending rod 32, adjusting the limiting of the left push plate 30 and the right push plate 31. Regardless of which direction the grinding head 5 is grinding, only one of the left push plate 30 and the right push plate 31 is always in a reciprocating state. When the grinding head 5 rotates and moves them to the area containing impurities in the grinding fluid, the reciprocating movement accelerates the flow of the grinding fluid, pushing the used grinding fluid to the other side of the grinding area of ​​the grinding head 5, away from the area to be ground.

[0027] The left push plate 30 and the right push plate 31 are located below the left side and above the right side of the grinding head 5, respectively. The left push plate 30 and the right push plate 31 are staggered so that they will not be blocked by each other when pushing the grinding fluid during their respective operations, ensuring smooth flow of the grinding fluid. A third spring is provided between the push ring 25 and the inner frame 9. The elastic force of the third spring causes the push ring 25 to return to its original position. A first torsion spring is provided between the locking rod 27 and the rotating rod 28. The elastic force of the first torsion spring supports the locking rod 27 and applies a pushing force to the locking rod 27 in the direction of the sliding rod 29, ensuring that the locking rod 27 is tightly attached to the surface of the sliding rod 29. A return spring is provided between the bending rod 32 and the grinding head 5. The elastic force of the return spring causes the bending rod 32 to return to its original position.

[0028] In this embodiment, when the nozzle 10 and the grinding head 5 are connected, the locking rod 27 is sleeved on the surface of the slide rod 29 to complete the connection between the slide rod 29 and the push ring 25. During the movement of the inner frame 9, the rack 19 moves, which in turn drives the gear 20 to rotate. The gear 20 then drives the gear ring 21 to rotate. The rotation of the gear ring 21 drives the rotating ring 22 via the sleeve rod 26. The rotating ring 22 then drives the triangular block 23 to rotate. The rotation of the triangular block 23 causes its surface to frequently press against the protruding rod 24, pushing the push ring 25 to move back and forth. The movement of the push ring 25 drives the sliding rod 29 to move left and right. The sliding rod 29, supported by the elastic element, drives the left push plate 30 and the right push plate 31 to move back and forth. When the grinding head 5 rotates, it moves the left push plate 30 or the right push plate 31 to the bottom of the grinding area, pushing the accumulated grinding fluid containing impurities at the bottom. This causes the grinding fluid to flow out of the flow groove and away from the grinding area in front. Furthermore, when the grinding head 5 moves to the left, the sliding ring 15 is in contact with the baffle 14. At this time, the sliding ring 15 drives the abutment rod 34. The inclined surface of the folding rod 32 is pressed, causing the folding rod 32 to move downwards, which drives the right limiting rod 33 into the round hole on the surface of the right push plate 31, locking the right push plate 31 and restricting its movement. When the grinding head 5 grinds to the left, only the left push plate 30 continues to move. When the grinding head 5 grinds to the right, the slip ring 15 no longer drives the abutment rod 34 to press the folding rod 32, and the right limiting rod 33 releases its restriction on the right push plate 31. At the same time, the left limiting rod 33 enters the round hole on the surface of the left push plate 30 to restrict the left push plate 30. When the grinding head grinds to the right, only the right push plate 31 is in a moving state. No matter which direction the grinding head 5 grinds, only one of the left push plate 30 and the right push plate 31 is always in a reciprocating state. When the grinding head 5 rotates and moves them to the grinding fluid containing impurities, the reciprocating movement accelerates the flow of the grinding fluid and pushes the used grinding fluid to the other side of the grinding area of ​​the grinding head 5, away from the area to be ground.

[0029] Please see Figure 1 - Figure 14Based on the above embodiments, in another embodiment of the present invention, push bars 35 are installed on the upper and lower sides of the inner wall of the inner frame 9. The push bars 35 are moved by the movement of the inner frame 9. Several rollers 36 are rotatably installed on the surface of the push bars 35. The movement of the push bars 35 drives the rollers 36 to move. The upper and lower sides of the inner wall of the left end of the outer frame 8 are rotatably installed with rocker arms 37. The rollers 36 frequently squeeze the rocker arms 37 and then pass over the rocker arms 37. An arc plate 38 is provided at the bottom of the rocker arms 37. The rocker arms 37 rotates after being squeezed, causing the arc plate 38 to deflect and contact the surface of the slurry pipe 7. The movement of the arc plate 38 pushes the slurry pipe 7 and conveys the slurry pipe 7 to an open direction outside the outer frame 8. This avoids the slurry pipe 7 from being squeezed and bent by the grinding head 5, which would affect the flow rate of the grinding fluid and ensure that the grinding fluid is sprayed out stably, thus ensuring that the grinding work continues stably.

[0030] A rotating block 39 is rotatably mounted at the bottom of the rocker arm 37. An arc plate 38 is slidably mounted at the bottom of the rotating block 39. A stop bar 41 is mounted on the surface of the arc plate 38. An arc strip 40 is mounted on the surface of the rocker arm 37. The arc surface of the arc strip 40 presses against the stop bar 41, causing the arc plate 38 to lift up to release force, avoiding excessive pressure on the shower pipe 7, and ensuring that the arc plate 38 can be smoothly reset without pushing the shower pipe 7 back. A second torsion spring is provided between the rocker arm 37 and the outer frame 8. The supporting force of the second torsion spring keeps the rocker arm 37 in an inclined state and resets after rotation. A fourth spring is provided between the arc plate 38 and the rotating block 39. The elastic force of the fourth spring causes the arc plate 38 to be lifted up and reset.

[0031] In this embodiment, when the grinding head 5 moves to the left, it is in a squeezing state on the slurry tube 7. The inner frame 9 moves, driving the pusher 35 to move, so that the roller 36 frequently squeezes the rocker arm 37 and passes over the rocker arm 37. After being squeezed, the rocker arm 37 rotates, causing the arc plate 38 to deflect and contact the surface of the slurry tube 7. The movement of the arc plate 38 pushes the slurry tube 7, conveying it to an open direction outside the outer frame 8. This prevents the slurry tube 7 from bending and folding due to the squeezing of the grinding head 5, which would affect the flow rate of the grinding fluid and ensure that the grinding fluid is sprayed out stably, thus ensuring that the grinding work continues stably. The rotation of the rocker arm 37 also drives the arc bar 40 to rotate. When the rocker arm 37 rotates and drives the arc plate 38 to move to a certain extent, the arc surface of the arc bar 40 squeezes the stop bar 41, causing the arc plate 38 to lift up to release the force, avoiding excessive squeezing of the slurry tube 7, and ensuring that the arc plate 38 can be smoothly reset without pushing the slurry tube 7 back.
