Description

Technical Field

[0001] The present invention relates to the technical field of numerical control equipment, and particularly relates to a high-precision numerically controlled horizontal machining center. Background Art

[0002] A horizontal machining center refers to a machining center with a spindle axis parallel to the worktable, which is mainly suitable for machining box parts. After clamping the workpiece, the computer selects different tools to sequentially complete the machining of multiple surfaces and processes of the workpiece. The horizontal machining center has the advantages of high machining accuracy, accurate positioning accuracy, strong thermal deformation and vibration resistance, and easy maintenance.

[0003] According to the patent number CN112775722B, the publication (announcement) date: February 22, 2022, discloses a horizontal double-sided machining center. It can realize the simultaneous machining of workpieces by two machining devices. A large amount of coolant is used during the machining process. The used coolant will leave cutting chips, so it becomes waste liquid. The drainage device provided in the drainage groove can lead the waste liquid and cutting chips to the discharge port to prevent the situation of accumulation and odor caused by excessive cutting chips. And the waste liquid and cutting chips flow into the coolant filtering device. After filtration, the cutting chips can be filtered out, and the filtered waste liquid can be recycled again, saving resources and costs.

[0004] In the prior art including the above patent, for the tool on the horizontal machining center, in order to avoid overheating and causing metal fatigue during use, coolant will be continuously sprayed on the tool during the rotation of the tool to cool the tool. Therefore, a large amount of coolant is used during machining. In order to realize the recycling of the coolant, the sprayed coolant will be collected, filtered and used. It is known that during the cutting process of machined parts, a large amount of cutting chips will be generated. The mixing of cutting chips and coolant will cause the cutting chips to retain coolant. Subsequently, during the cleaning process of the cutting chips, it is easy to take out the coolant remaining on the cutting chips together, thereby causing the loss of coolant. At the same time, the coolant remaining on the cutting chips is not convenient for cleaning the cutting chips. Summary of the Invention

[0042] 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 introduced in detail below in conjunction with the accompanying drawings.

[0043] As Figures 1-15 shown, a high-precision CNC horizontal machining center includes a base 1 with a slide groove 11 opened at the top. A tapered block 14 is provided on the inner wall of one side of the slide groove 11. A scraper 4 is slidably arranged in the slide groove 11. A shoveling part 42 that moves along the slide groove 11 is provided on the outer wall of one side of the scraper 4. The shoveling part 42 moves relative to the tapered block 14 to gather and squeeze the cutting chips;

[0044] The shoveling part 42 is provided with a first air blowing unit and a second air blowing unit;

[0045] The first air blowing unit includes a liquid removing air cavity 45, which blows air when the shoveling part 42 is attached to the tapered block 14;

[0046] The second air blowing unit includes a blowing material air outlet 48, which is distributed on the high-position side of the shoveling part 42 and blows air when the shoveling part 42 is away from the tapered block 14 by a predetermined distance.

[0047] Specifically, the shovel part 42 is movably arranged on the inclined surface on one side of the conical block 14, and the inclined surfaces of the conical block 14 and the shovel part 42 match each other. The shovel part 42 includes a lower position and a higher position. When the scraping part 4 slides to make the shovel part 42 shovel up the cutting chips, the cutting chips located in the chute 11 are shoveled by the shovel part 42 along the lower position of the shovel part 42 onto the shovel part 42, and then the cutting chips are pressed and gathered and the coolant on the cutting chips is extruded through the mutual fitting and extrusion between the shovel part 42 and the inclined surface of the conical block 14.

[0048] And a plurality of air-blowing platforms 43 are arranged in an array on the shovel part 42. The liquid-removing air cavities 45 are multiple and their air outlets are respectively located on one side of the air-blowing platforms 43, and the air outlets on the air-blowing platforms 43 face the shoveling surface of the shovel part 42.

[0049] Further, the scraping part 4 can be pushed by a hydraulic cylinder to slide in the chute 11; it can also be driven by a motor in cooperation with gears and racks to slide the scraping part 4; or any other known way to drive the scraping part 4 to slide by those skilled in the art is acceptable.

[0050] Moreover, air can be blown along the liquid-removing air cavity 45 by connecting a blower to the liquid-removing air cavity 45 to make the blower blow air into the liquid-removing air cavity 45; it can also be to open an activity cavity communicating with the liquid-removing air cavity 45 in the scraping part 4 and use a piston to move in the activity cavity to squeeze and blow air; or any other known way to drive the liquid-removing air cavity 45 to blow air by those skilled in the art is acceptable.

[0051] Furthermore, a blower can be connected to the material-blowing air outlet 48 to make the blower blow air into the material-blowing air outlet 48; it can also be to open an activity cavity communicating with the material-blowing air outlet 48 in the scraping part 4 and use a piston to move in the activity cavity to squeeze and blow air; or any other known way to drive the material-blowing air outlet 48 to blow air by those skilled in the art is acceptable.

[0052] In the above technical solution, after the machining part completes the cutting operation on the base 1 and the coolant cools the cutting tool, the cutting chips and the coolant then fall into the chute 11 on the base 1. When it is necessary to collect the cutting chips, at this time, the scraping part 4 slides in the chute 11 to use the shovel part 42 to scrape the cutting chips on the chute 11 and make the cutting chips gather close to the conical block 14, and then under the extrusion of the conical block 14 and the shovel part 42, the cutting chips extrude the attached coolant, thereby realizing the first liquid-removing operation, and the cutting chips are squeezed and gathered for easy collection. When the conical block 14 and the shovel part 42 squeeze the cutting chips, at this time, the liquid-removing air cavity 45 of the first air-blowing unit blows air to perform a secondary liquid-clearing operation on the squeezed cutting chips, thereby reducing the coolant being cleaned along with the cutting chips, and eliminating the coolant on the cutting chips is convenient for recycling the cutting chips. When the scraping part 4 resets, at this time, when the shovel part 42 is away from the conical block 14 to a predetermined distance, the material-blowing air outlet 48 blows air, so that the cutting chips extruded on the shovel part 42 fall along the shovel part 42.

[0053] As another embodiment further provided by the present invention, it further includes a first air chamber 41 opened in the scraping member 4 and communicating with a plurality of liquid-removing air chambers 45. A first piston plate 35 is slidably arranged in the first air chamber 41, and sealing plates 54 are respectively slidably arranged in the liquid-removing air chambers 45. The sealing plates 54 are used to cut off / open the air outlet of the liquid-removing air chambers 45.

[0054] Specifically, when the scraping member 4 is driven to move and fit onto the conical block 14, at this time, by driving the first piston plate 35 to move in the first air chamber 41, as Figure 10 shown, the air in the first air chamber 41 is squeezed into the liquid-removing air chambers 45 and sprayed out along the air outlets of the liquid-removing air chambers 45, so as to blow the cutting chips clamped between the shoveling part 42 and the conical block 14 to remove the coolant attached to the cutting chips. By controlling the sliding of the sealing plates 54 to cut off or open the air outlet of the liquid-removing air chambers 45, when the sealing plates 54 slide to cut off the liquid-removing air chambers 45, along with the first piston plate 35 moving towards the liquid-removing air chambers 45 in the first air chamber 41, due to the cut-off of the sealing plates 54, the air pressure in the first air chamber 41 increases. Then, by sliding the sealing plates 54 again to open the liquid-removing air chambers 45, at this time, the compressed gas quickly sprays out along the air outlets of the liquid-removing air chambers 45 to enhance the blowing and cleaning of the coolant attached to the cutting chips.

[0055] Furthermore, the first piston plate 35 can be pushed by a hydraulic cylinder to slide in the first air chamber 41; it can also be driven by a motor in cooperation with gears and racks to slide the first piston plate 35; or any other known way for those skilled in the art to drive the first piston plate 35 to slide is acceptable.

[0056] Even further, the sealing plates 54 can be pushed by an electric push rod to slide in the liquid-removing air chambers 45; it can also be driven by a hydraulic cylinder to slide; or any other known way for those skilled in the art to drive the sealing plates 54 to slide is acceptable.

[0057] As another embodiment provided by the present invention, movable plates 5 are movably arranged on the shoveling part 42 in a linear array. The movable plates 5 are kept moving synchronously with the sealing plates 54 through a connecting rod assembly.

[0058] Specifically, as Figure 7 shown, groove parts 44 are linearly arrayed and opened on the shoveling surface of the shoveling part 42. The movable plates 5 are respectively slidably arranged in the groove parts 44. The connecting rod assembly includes a main connecting rod 53 and extension rods 52 respectively fixedly installed on the movable plates 5. The first end of the main connecting rod 53 is hinged to the first end of the extension rod 52, and the second end of the main connecting rod 53 is hinged to the sealing plates 54. Ventilation grooves 55 are opened on the sealing plates 54.

[0059] An arc portion 17 matching the extrusion surface of the movable plate 5 is provided on the inclined surface of the tapered block 14. Ventilation grooves 51 are arranged in a linear array on the extrusion surface of the movable plate 5. The air outlet of the liquid removal air chamber 45 is located on the inner wall of one side of the groove portion 44, and ventilation grooves 46 are formed in the inner wall of the groove portion 44 on the side opposite to the air outlet of the liquid removal air chamber 45.

[0060] Further, when the scraping member 4 is driven to move so that the shoveling portion 42 and the movable plate 5 are attached to the tapered block 14 and the arc portion 17, at this time, the cuttings shoveled up are located on the movable plate 5. At the same time, the first piston plate 35 is driven to move in the first air chamber 41 to squeeze the air in the first air chamber 41 into the liquid removal air chamber 45. At this time, since the sealing plate 54 separates the liquid removal air chamber 45, the air pressure of the air squeezed in the first air chamber 41 increases. Through the arc portion 17 covering the movable plate 5 and the extrusion between the scraping member 4 and the tapered block 14, the movable plate 5 moves into the groove portion 44. When the movable plate 5 moves, as Figure 7 shown, the extension rod 52 cooperates with the main connecting rod 53 to drive the sealing plate 54 to move, so as to realize the synchronous movement of the movable plate 5 and the sealing plate 54. The ventilation groove 55 is used to open the liquid removal air chamber 45. At this time, the compressed gas quickly sprays out along the air outlet of the liquid removal air chamber 45. As Figure 8 shown, the air flow circulates along the ventilation groove 51 and the gap between the arc portion 17 and the movable plate 5, and then blows off the coolant attached to the cuttings. Then, the coolant and the air flow flow along the ventilation groove 46 and flow out through the shoveling surface of the shoveling portion 42.

[0061] As another embodiment provided by the present invention, it further includes a driving unit, which includes a pushing block 3 and a main hydraulic cylinder 37 for driving the pushing block 3 to slide in the sliding groove 11. Guide rods 33 symmetrically arranged on the pushing block 3 are slidably arranged on the scraping member 4, and one ends of the guide rods 33 are respectively fixedly installed on the first piston plate 35. Main springs 34 are respectively sleeved on the outer walls of the guide rods 33 between the pushing block 3 and the scraping member 4.

[0062] Specifically, damping members 57 are symmetrically arranged between the movable plate 5 and the bottom of the groove portion 44. A resistance spring 56 is fixedly installed on the sealing plate 54, and the resistance spring 56 and the damping members 57 are respectively fixedly installed on the scraping member 4. The first end of the main spring 34 is fixedly installed on the pushing block 3, and the second end of the main spring 34 is fixedly installed on the scraping member 4.

[0063] By using the main hydraulic cylinder 37 fixedly installed in the chute 11 to push the push block 3 to slide, at this time, under the action of the main spring 34, the scraping member 4 is pushed to move. When the scraping member 4 moves, the shoveling part 42 shovels up the cutting chips in the chute 11 onto the shoveling part 42 and the movable plate 5. Then, when the shoveling part 42 and the movable plate 5 are attached to the conical block 14 and the arc part 17, the scraping member 4 is blocked and stops moving. Then, under the continuous pushing of the main hydraulic cylinder 37 to move the push block 3, the first piston plate 35 moves with the push block 3 and slides in the first air blowing cavity 41 to squeeze the air in the first air blowing cavity 41 into the liquid removing air cavity 45. At this time, since the sealing plate 54 blocks the liquid removing air cavity 45, the air pressure in the first air blowing cavity 41 that is squeezed increases. By using the resistance spring 56 and the damping member 57 to increase the moving resistance of the movable plate 5, that is, when the moving resistance of the movable plate 5 increases, the push block 3 needs to move more towards the scraping member 4 side to enhance the extrusion force between the scraping member 4 and the conical block 14. At this time, the air pressure in the first air blowing cavity 41 that is squeezed further increases.

[0064] Furthermore, the arc part 17 covers the movable plate 5 and cooperates with the extrusion between the scraping member 4 and the conical block 14 to make the movable plate 5 move into the groove part 44. At the same time, the cutting chips are compressed and gathered, and the coolant attached to the cutting chips is extruded. Then, under the movement of the movable plate 5, as Figure 7 shown, the extension rod 52 cooperates with the main connecting rod 53 to drive the sealing plate 54 to move. When the ventilation groove 55 is located in the liquid removing air cavity 45, at this time, the ventilation groove 55 is used to make the gas in the liquid removing air cavity 45 flow, and the compressed gas quickly sprays out along the air outlet of the liquid removing air cavity 45. As Figure 8 shown, the air flow flows along the air permeable groove 51 and the gap between the arc part 17 and the movable plate 5, and then blows off the coolant attached to the cutting chips. Then, the coolant and the air flow flow along the ventilation groove 46 and flow out through the shoveling surface of the shoveling part 42.

[0065] As another embodiment provided by the present invention, a second air blowing cavity 49 communicating with the blowing material air outlet 48 is opened in the scraping member 4. A second piston plate 68 is slidably arranged in the second air blowing cavity 49. A locking member 6 that moves synchronously with the second piston plate 68 is slidably arranged on the scraping member 4. A pulling spring 66 is arranged between the locking member 6 and the scraping member 4.

[0066] Specifically, one end of the force receiving rod 67 provided on the locking member 6 is fixedly installed on the outer wall of one side of the second piston plate 68, and a mounting plate 47 is arranged on the top of the scraping member 4. The first end of the pulling spring 66 is fixedly installed on the mounting plate 47, and the second end of the pulling spring 66 is fixedly installed on the locking member 6.

[0067] As Figure 10As shown, a first one-way ventilation valve 58 is provided between the first air blowing chamber 41 and the liquid removing air chamber 45, and a second one-way ventilation valve 59 is provided on the inner wall of the first air blowing chamber 41. When the first piston plate 35 moves in the first air blowing chamber 41 to compress air, the first one-way ventilation valve 58 opens to allow the air in the first air blowing chamber 41 to enter the liquid removing air chamber 45, and at the same time the second one-way ventilation valve 59 closes. Then, when the first piston plate 35 moves away from the shovel part 42 and moves in the first air blowing chamber 41, at this time the first one-way ventilation valve 58 closes and the second one-way ventilation valve 59 opens to allow external air to enter the first air blowing chamber 41 again, thereby avoiding the suction force brought when the first piston plate 35 resets, causing part of the coolant to be sucked into the liquid removing air chamber 45 to contaminate the cavity of the liquid removing air chamber 45.

[0068] When the extrusion and compression of the cutting chips and the blowing to remove the coolant on the cutting chips are completed, the main hydraulic cylinder 37 pulls the push block 3 to move back to its original position. At this time, the main spring 34 releases its stored energy, so that the push block 3 continuously fits on the conical block 14 while the scraping part 4 moves. At the same time, the first piston plate 35 moves back to its original position and external air enters the first air blowing chamber 41 again. When the release of the stored energy of the main spring 34 ends and the push block 3 moves, the main spring 34 pulls the scraping part 4 to move, so that the scraping part 4 moves away from the conical block 14. At this time, the resistance spring 56 and the damping part 57 push the movable plate 5 to move back to its original position, and drive part of the cutting chips on the movable plate 5 to slide down along the inclined surfaces of the movable plate 5 and the shovel part 42 under the movement of the movable plate 5.

[0069] At this time, the locking part 6 is driven to slide to extend and store the energy of the pulling spring 66, and then the pulling of the locking part 6 is released to quickly pull the locking part 6 back to its original position by the reset of the pulling spring 66. At this time, the second piston plate 68 moves in the second air blowing chamber 49 to squeeze the air in the second air blowing chamber 49 and blow it out along the blowing tuyere 48. The air blown by the blowing tuyere 48 is directed towards the shovel part 42 and the movable plate 5, so as to blow off the compressed cutting chips on the shovel part 42 and the movable plate 5 when the scraping part 4 and the conical block 14 move away from each other.

[0070] Furthermore, the locking part 6 can be unlocked and released when moving. A mechanical claw can be provided at the pushing end of the electric push rod to hold the locking part 6, and then the mechanical claw releases the locking part 6 when the locking part 6 reaches a certain position; it can also be that a magnetic attracting part is installed at the pushing end of the electric push rod and then the locking part 6 and the magnetic attracting part are separated and released under the shielding of the corresponding stop block; or any other method known to those skilled in the art to drive the locking part 6 to slide and then be able to release the fixing of the locking part 6 can be used.

[0071] As the optimal embodiment provided by the present invention, it further includes a pulling and locking mechanism, which includes a driving rod 32 slidably arranged on the scraping member 4 and a locking block 38 slidably arranged on the driving rod 32. The first end of the locking block 38 is in snap-fit with the card slot opened at the bottom end of the hook locking member 6, and is pushed by one end of the ejector rod 61 slidably arranged in the hook locking member 6 to disengage the locking block 38.

[0072] Specifically, as Figure 11 and Figure 12 shown, a locking spring 39 is fixedly installed at the second end of the locking block 38, and the first end of the locking spring 39 is fixedly installed on the driving rod 32.

[0073] When it is necessary to use the air blown by the blowing air outlet 48 to blow off the compressed cutting chips on the shoveling part 42 and the movable plate 5, at this time, by pushing the driving rod 32 to move the locking block 38 below the hook locking member 6, and then under the action of the locking spring 39 pushing the locking block 38, the locking block 38 is snap-locked in the card slot opened at the bottom end of the hook locking member 6. By driving the driving rod 32 to slide again to drive the hook locking member 6 to slide, at this time, the pulling spring 66 extends and stores energy. When the hook locking member 6 reaches the appropriate position, by sliding the ejector rod 61 so that one end of the ejector rod 61 pushes the locking block 38 in the card slot, at this time, the locking block 38 disengages from the card slot so that the locking block 38 releases the snap-locking of the hook locking member 6. Furthermore, the hook locking member 6 is quickly pulled back to its original position by the reset of the pulling spring 66. At this time, the second piston plate 68 moves in the second air blowing chamber 49 so that the air in the second air blowing chamber 49 is squeezed and blown out along the blowing air outlet 48 to blow off the compressed cutting chips on the shoveling part 42 and the movable plate 5.

[0074] Furthermore, the driving rod 32 can be pushed and slid on the scraping member 4 by an electric push rod; it can also be pushed and slid by a hydraulic cylinder; or any other known way for those skilled in the art to drive the driving rod 32 to slide is acceptable.

[0075] Even further, the ejector rod 61 can be slid by a motor cooperating with gears and connecting rods; it can also be pushed and slid by an electric push rod; or any other known way for those skilled in the art to drive the ejector rod 61 to slide is acceptable.

[0076] As another embodiment provided by the present invention, an impact block 64 is slidably arranged in the hook locking member 6, and the impact block 64 slides in the inclined slot 62 opened on the ejector rod 61 to drive the ejector rod 61 to slide. The baffle 65 arranged on the top of the scraping member 4 is located on the moving path of the impact block 64. The first end of the driving rod 32 is fixedly installed on the push block 3.

[0077] Specifically, a limiting spring 63 is fixedly installed on the ejector rod 61, and the first end of the limiting spring 63 is fixedly installed on the hook locking member 6, and since the first end of the driving rod 32 is fixedly installed on the push block 3.

[0078] As Figure 11 and Figure 12 shown, when the main hydraulic cylinder 37 pushes the push block 3 to move, at this time, under the action of the main spring 34, the scraping member 4 is pushed to move. When the scraping member 4 moves, at this time, the shovel part 42 shovels up the cutting chips in the chute 11 onto the shovel part 42 and the movable plate 5. Then, when the shovel part 42 and the movable plate 5 are attached to the conical block 14 and the arc part 17, at this time, the scraping member 4 is blocked and stops moving. Then, under the continuous pushing of the main hydraulic cylinder 37 to move the push block 3, the first piston plate 35 moves with the push block 3 and slides in the first air-blowing cavity 41 to squeeze the air in the first air-blowing cavity 41 into the liquid-removing air cavity 45. At this time, since the sealing plate 54 blocks the liquid-removing air cavity 45, the air pressure in the first air-blowing cavity 41 that is squeezed increases, and the driving rod 32 moves on the top of the scraping member 4. At the same time, the main spring 34 is squeezed and stores energy.

[0079] Furthermore, the arc part 17 covers the movable plate 5, and through the extrusion between the scraping member 4 and the conical block 14, the movable plate 5 moves into the groove part 44. At the same time, the cutting chips are compressed and aggregated, and the coolant attached to the cutting chips is extruded. Then, under the movement of the movable plate 5, as Figure 7 shown, the extension rod 52 cooperates with the main connecting rod 53 to drive the sealing plate 54 to move. When the ventilation groove 55 is located in the liquid-removing air cavity 45, at this time, the ventilation groove 55 is used to make the gas in the liquid-removing air cavity 45 flow. The compressed gas quickly sprays out along the air outlet of the liquid-removing air cavity 45, as Figure 8 shown, the air flow flows along the air-permeable groove 51 and the gap between the arc part 17 and the movable plate 5, and then blows off the coolant attached to the cutting chips. Then, the coolant and the air flow flow along the air-permeable groove 46 and flow out through the shovel surface of the shovel part 42.

[0080] When the locking block 38 moves below the locking member 6 and under the action of the locking spring 39 pushing the locking block 38, the locking block 38 is clamped and locked in the card slot opened at the bottom end of the locking member 6. At this time, the extrusion and compression of the cutting chips are completed, and the air blows to remove the coolant on the cutting chips, and the movement of the push block 3 stops.

[0081] By restarting the main hydraulic cylinder 37 again and pulling the pushing block 3 to move back to its original position, at this time the main spring 34 releases the stored energy, so that the scraping part 4 continuously fits on the conical block 14 while the pushing block 3 keeps moving, that is, the pushing block 3 moves relative to the scraping part 4. At this time, the driving rod 32 pulls the locking part 6 to move and the pulling spring 66 extends to store energy. It can be known that the stored energy released by the main spring 34 is greater than the pulling force of the pulling spring 66. At the same time, the first piston plate 35 moves back to its original position and external air enters the first air blowing cavity 41 again. Along with the main spring 34 releasing the stored energy, the locking part 6 gradually approaches the baffle 65. Under the blocking of the baffle 65 and the release of the stored energy by the main spring 34, the first end of the impact block 64 contacts the baffle 65, and at the same time, the impact block 64 slides on the locking part 6 so that the second end of the impact block 64 slides in the inclined slot 62 to drive the ejector rod 61 to slide. Due to the sliding of the ejector rod 61, one end of the ejector rod 61 pushes the locking block 38 in the card slot. When the locking block 38 disengages from the card slot, at this time the release of the stored energy by the main spring 34 ends. Then, under the continuous movement of the pushing block 3, the main spring 34 pulls the scraping part 4 to move, so that the scraping part 4 moves away from the conical block 14. At this time, the resistance spring 56 and the damping part 57 push the movable plate 5 to move back to its original position, and the movement of the movable plate 5 drives part of the cutting chips on the movable plate 5 to slide down along the inclined surfaces of the movable plate 5 and the shoveling part 42. At the same time, because the locking block 38 releases the locking of the locking part 6, and then the pulling spring 66 quickly pulls the locking part 6 back to its original position during the reset. At this time, the second piston plate 68 moves in the second air blowing cavity 49 so that the air in the second air blowing cavity 49 is squeezed out and blown out along the air blowing nozzle 48 to blow off the compressed cutting chips on the shoveling part 42 and the movable plate 5. At the same time, because the pulling spring 66 pulls the locking part 6 to move, the locking part 6 quickly impacts on the scraping part 4, so that the scraping part 4 generates vibration to facilitate the falling of the compressed cutting chips on the movable plate 5.

[0082] As another embodiment provided by the present invention, a push plate 15 is slidably arranged on the conical block 14 and is located on the moving path of the shoveling part 42. The push plate 15 blocks the oil groove 12 opened below the conical block 14 in the sliding groove 11.

[0083] Specifically, the first end of the push plate 15 is fixedly installed with an auxiliary spring 16, and the auxiliary spring 16 is fixedly installed on the conical block 14. The second end of the push plate 15 and one side edge of the oil groove 12 notch maintain a certain distance, such as Figure 14 shown, specifically it can be 0.5 mm - 2 mm, so as to facilitate the coolant to flow into the oil groove 12 along the gap between the second end of the push plate 15 and one side edge of the oil groove 12 notch. At the same time, the push plate 15 slides in the buffer cavity opened on the conical block 14. One inner wall of the buffer cavity is provided with a through hole 81, and a buffer one-way air valve 8 is arranged at one end of the through hole 81 in the buffer cavity. A fine pore channel 82 is opened between the through hole 81 and the buffer cavity.

[0084] When the shovel part 42 moves to the notch of the oil tank 12, the push plate 15 blocks the chips scooped up by the shovel part 42 from falling directly into the oil tank 12. Then, as the scraper 4 continues to move, the push plate 15 blocks the chips scooped up by the shovel part 42, so that the chips are pushed onto the movable plate 5. At the same time, the push plate 15 is squeezed and moved into the buffer cavity. The auxiliary spring 16 is squeezed and accumulates force. At this time, the buffer one-way air valve 8 opens, and the gas in the buffer cavity flows along the buffer one-way air valve 8 and the fine hair channel 82 to the through hole 81 and is discharged through the through hole 81. Then, when the shovel part 42 fits the conical block 14, as shown in FIG. Figure 15 shown.

[0085] When the shovel portion 42 is away from the conical block 14, the auxiliary spring 16 is used to release the stored force to push the push plate 15 to reset. At this time, the buffer one-way air valve 8 is closed, and the external air slowly enters the buffer cavity along the fine pores 82, thereby slowly resetting the push plate 15.

[0086] As another embodiment further provided by the present invention, a filter frame 2 is hingedly provided on the inner wall of one side of the oil tank 12, and a flip rod 21 is fixedly installed on the filter frame 2;

[0087] It also includes a push block 3 provided with a hook plate 23, and the hook plate 23 is movably assembled for the following three station settings:

[0088] At station 1, the push block 3 approaches the conical block 14 so that the hook plate 23 is turned over and located on the side of the turning rod 21 opposite to the push block 3;

[0089] In station 2, the push block 3 is away from the conical block 14 so that the hook plate 23 moves the turning rod 21 to drive the filter frame 2 to turn and tilt;

[0090] At station three, the hook plate 23 is separated from the turning rod 21 .

[0091] Specifically, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a force rod 31 is fixedly mounted on the push block 3, and a shielding portion 36 is provided at the end of the force rod 31. The hook plate 23 is hingedly mounted on the force rod 31, and a first torsion spring 24 is sleeved on the hinge axis of the hook plate 23. The first end of the first torsion spring 24 is fixedly mounted on the force rod 31, and the second end of the first torsion spring 24 is fixedly mounted on the hook plate 23. The first torsion spring 24 drives the hook plate 23 to flip and fit on the shielding portion 36. Figure 13 As shown, a flip groove 18 is provided on the slide groove 11, and a flip rod 21 is movably arranged in the flip groove 18. A storage cavity 19 is provided on the inner wall of one side of the oil groove 12, and a storage box 7 is movably arranged in the storage cavity 19.

[0092] When the push block 3 approaches the conical block 14, at this time in the first working position, the force rod 31 moves with the push block 3, and then Figure 5 As shown, the hook plate 23 is turned over under the cover of the turning rod 21 , and then when the hook plate 23 passes over the turning rod 21 , the first torsion spring 24 drives the hook plate 23 to turn over and fit onto the blocking portion 36 again.

[0093] When the push block 3 is away from the conical block 14, at this time in the state of the second station, the hook plate 23 is used to flip the flip rod 21 to drive the filter frame 2 to flip. At this time, the compressed cutting chips along the shovel portion 42 and the movable plate 5 fall onto the filter frame 2, and the cutting chips slide along the inclined surface of the filter frame 2 to the storage box 7 in the storage cavity 19 for collection, thereby preventing the coolant from adhering to the compressed cutting chips again when the filter frame 2 is used subsequently, and preventing the cutting chips from clogging the filter frame 2.

[0094] When the push block 3 is away from the conical block 14 by a certain position, in the third station state, the hook plate 23 is separated from the flip rod 21, and the filter frame 2 is flipped down and reset again by its own weight, so as to facilitate the subsequent use of the filter frame 2.

[0095] As the optimal embodiment further provided by the present invention, an elastic reset member is movably provided on the filter frame 2, and a support plate 13 is provided on the inner wall of one side of the oil tank 12. When the hook plate member 23 is located at the third station, the elastic reset member drives the filter frame 2 to reset and hit the support plate 13.

[0096] Specifically, the elastic reset member can be a second torsion spring 22, a first end of the second torsion spring 22 is fixedly mounted on the filter frame 2, and a second end of the second torsion spring 22 is fixedly mounted on the base 1, and the second torsion spring 22 drives the filter frame 2 to flip and fit onto the support plate 13.

[0097] The machined parts are cut on the base 1 and the coolant cools the tool, and then the chips and coolant fall into the chute 11 on the base 1. When the chips need to be collected, the push block 3 is pushed to move by the main hydraulic cylinder 37. At this time, the scraper 4 is pushed to move under the action of the main spring 34. When the scraper 4 moves, the shovel part 42 shovels the chips in the chute 11 onto the shovel part 42 and the movable plate 5.

[0098] When the shovel portion 42 moves to the groove of the oil groove 12 at the low position, the push plate 15 is used to block the chips scooped up by the shovel portion 42 from falling directly into the oil groove 12. Then, as the scraper 4 continues to move, the push plate 15 is used to block the chips scooped up by the shovel portion 42, so that the chips are pushed onto the movable plate 5. At the same time, the push plate 15 is squeezed and moved into the buffer cavity, and the auxiliary spring 16 is squeezed and accumulated. At this time, the buffer one-way air valve 8 opens, and the gas in the buffer cavity flows along the buffer one-way air valve 8 and the fine pores 82 to the through hole 81 and is discharged through the through hole 81.

[0099] Then, when the shovel part 42 and the movable plate 5 are attached to the conical block 14 and the arc part 17, at this time, the scraping part 4 is blocked and stops moving. Then, under the continuous pushing of the main hydraulic cylinder 37 to move the pushing block 3, the first piston plate 35 moves with the pushing block 3 and slides in the first air blowing cavity 41 to squeeze the air in the first air blowing cavity 41 into the liquid removing air cavity 45. At this time, since the sealing plate 54 blocks the liquid removing air cavity 45 to increase the air pressure of the air squeezed in the first air blowing cavity 41, and the driving rod 32 moves on the top of the scraping part 4, while the main spring 34 is squeezed and stores energy.

[0100] Furthermore, the arc part 17 covers the movable plate 5, and through the extrusion between the scraping part 4 and the conical block 14, the movable plate 5 moves into the groove part 44. At the same time, the cutting chips are compressed and aggregated, and the coolant attached to the cutting chips is squeezed out. Then, under the movement of the movable plate 5, as Figure 7 shown, the extension rod 52 cooperates with the main connecting rod 53 to drive the sealing plate 54 to move. When the ventilation groove 55 is located in the liquid removing air cavity 45, at this time, the ventilation groove 55 is used to make the gas in the liquid removing air cavity 45 flow, and the compressed gas quickly sprays out along the air outlet of the liquid removing air cavity 45. As Figure 8 shown, the air flow flows along the air permeable groove 51 and the gap between the arc part 17 and the movable plate 5, and then blows off the coolant attached to the cutting chips. Then, the coolant and the air flow flow along the air permeable groove 46 and flow out through the shovel surface of the shovel part 42.

[0101] When the locking block 38 moves below the locking part 6 and under the action of the locking spring 39 pushing the locking block 38, the locking block 38 is clamped and locked in the clamping groove opened at the bottom end of the locking part 6. At this time, the extrusion and compression of the cutting chips are completed, and the air blows to remove the coolant on the cutting chips, and the movement of the pushing block 3 stops.

[0102] From the movement of the pushing block 3 to the scraping part 4 to the stop of the pushing block 3 as described above is the state of working station one. In the state of working station one, the force application rod 31 moves with the pushing block 3. As Figure 5 shown, the hook plate part 23 is flipped under the shielding of the turning rod 21. Then, when the hook plate part 23 passes over the turning rod 21, the first torsion spring 24 drives the hook plate part 23 to flip again and fit on the shielding part 36.

[0103] By restarting the main hydraulic cylinder 37 again and pulling the pushing block 3 to move back to its original position, at this time the main spring 34 releases the stored energy, so that the scraping part 4 continuously fits on the conical block 14 while the pushing block 3 keeps moving, that is, the pushing block 3 moves relative to the scraping part 4. At this time, the driving rod 32 pulls the locking part 6 to move and the pulling spring 66 extends and stores energy. It can be known that the stored energy released by the main spring 34 is greater than the pulling force of the pulling spring 66. At the same time, the first piston plate 35 moves back to its original position and external air enters the first air-blowing cavity 41 again. Along with the main spring 34 releasing the stored energy to make the locking part 6 gradually approach the baffle 65, under the shielding of the baffle 65 and the main spring 34 releasing the stored energy, the first end of the impact block 64 contacts the baffle 65, and at the same time the impact block 64 slides on the locking part 6 so that the second end of the impact block 64 slides in the inclined notch 62 to drive the ejector rod 61 to slide. Due to the sliding of the ejector rod 61, one end of the ejector rod 61 pushes the locking block 38 in the card slot. When the locking block 38 disengages from the card slot, at this time the release of the stored energy of the main spring 34 ends. Then, under the continuous movement of the pushing block 3, the main spring 34 pulls the scraping part 4 to move, so that the scraping part 4 moves away from the conical block 14. At this time, the resistance spring 56 and the damping part 57 push the movable plate 5 to move back to its original position, and drive some of the cutting chips on the movable plate 5 to slide and fall along the inclined surfaces of the movable plate 5 and the shoveling part 42 during the movement of the movable plate 5.

[0104] At this time, the auxiliary spring 16 releases the stored energy to push the push plate 15 back to its original position. At this time, the buffer check valve 8 closes, and external air slowly enters the buffer cavity along the fine pore channels 82, so that the push plate 15 slowly returns to its original position.

[0105] At the same time, because the locking block 38 releases the locking of the locking part 6, and then the pulling spring 66 quickly pulls the locking part 6 back to its original position during the reset. At this time, the second piston plate 68 moves in the second air-blowing cavity 49 so that the air in the second air-blowing cavity 49 is squeezed and blown out along the blowing port 48 to blow off the compressed cutting chips on the shoveling part 42 and the movable plate 5. At the same time, because the pulling spring 66 pulls the locking part 6 to move, the locking part 6 quickly impacts on the scraping part 4, and then the scraping part 4 vibrates to facilitate the falling of the compressed cutting chips on the movable plate 5.

[0106] From the pulling of the pushing block 3 by the main hydraulic cylinder 37 to move back to its original position to the locking part 6 quickly impacting on the scraping part 4 as described above is the state of working station two. In the state of working station two, the hook plate part 23 moves back to its original position with the pushing block 3 to toggle the turning lever 21 to turn and drive the filter screen frame 2 to turn. The turning angle of the filter screen frame 2 is 0° - 50°.

[0107] At this time, the compressed cutting chips along the shoveling part 42 and the movable plate 5 fall on the filter screen frame 2, and slide along the inclined surface of the filter screen frame 2 and fall into the storage box 7 in the storage cavity 19 for collection.

[0108] When the compressed chips fall into the storage box 7, at this time, the push block 3 continues to move, so that the hook plate member 23 disengages from the turning rod 21. At this time, it is in the state of working station three. Due to the self-weight of the filter screen frame 2 itself and the second torsion spring 22, the filter screen frame 2 is driven to turn over, so that the filter screen frame 2 quickly impacts on the support plate 13. As a result, some of the chips embedded on the filter screen frame 2 become loose due to the impact of the filter screen frame 2, facilitating the subsequent turning over of the filter screen frame 2 and the sliding of the chips into the storage box 7.

[0109] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
