DETAILED DESCRIPTION

[0037] The following will be combined with the Figures 1-10 , further describing the technical solutions in the embodiments of the present invention in detail. The described embodiments are merely possible technical implementations of the present invention, but are not limited thereto. Those skilled in the art can fully combine the embodiments of the present invention, and other embodiments derived without inventive effort are also within the scope of protection of the present invention.

[0038] This application mainly adopts a multi-point flushing and segmented waste chip cleaning solution to achieve the effect of improving the chip removal effect of ultra-large gantry machine tools and energy saving and environmental protection. The following is a further detailed description of this application.

[0039] The embodiment of the present application discloses a chip removal system for an ultra-large gantry machining center.

[0040] Example 1 Reference Figure 1 、 Figure 2 A chip removal system for an ultra-large gantry machining center includes a chip trough 2, a chip removal device 3, a connecting structure 4, and a first flushing structure 5. The number of chip troughs 2 is two groups, and each group of chip troughs 2 extends along the length direction of the worktable 1 of the machine tool. The two groups of chip troughs 2 are arranged on both sides of the worktable 1, so that the waste chips on the worktable 1 can be cleaned into the two groups of chip troughs 2. The chip removal device 3 is provided in N groups, where N is a positive integer greater than zero. In this embodiment, N=1 is taken as an example, and the corresponding connecting structure 4 is also a group. The connecting structure 4 of this embodiment includes an intermediate channel 41, which is arranged in a base below the chip trough 2 along a direction perpendicular to the length of the chip trough 2. Each chip trough 2 is connected to the intermediate channel 41 through a countersunk hole, so that the waste chips in the chip trough 2 flow into the intermediate channel 41 along with the cutting fluid.

[0041] Reference Figure 1 、 Figure 3 and Figure 4 In this embodiment, the number of first flushing structures 5 is N+1 groups, and the corresponding number of first flushing structures 5 is two groups. The number of first flushing structures 5 in each group is two. Each first flushing structure 5 includes a first submersible pump 51 and a first pipe 52. The end of each first pipe 52 is connected to an end pipe 53, and the outlet of the end pipe 53 forms a flushing end 54. The two groups of flushing ends 54 are arranged in a row at both ends of the chip groove 2 along the length direction of the chip groove 2, and the two flushing ends 54 in the same group are located in the two groups of chip grooves 2.

[0042] Reference Figure 2In this embodiment, the middle channel 41 is set at the center position of the two chip removal grooves 2, and the two groups of flushing ends 54 are symmetrically arranged about the middle channel 41, so that the chip liquid sprayed by the two groups of flushing ends 54 flushes the debris in the chip removal groove 2 from both ends to the middle channel 41. The distance between the flushing end 54 and the middle channel 41 is L. Assume that the maximum distance that the chip liquid sprayed by the flushing end 54 can flush the waste chips in the chip removal groove 2 is H. The value of H is related to the diameter and design angle of the end pipe 53, the power of the first submersible pump 51 and other factors. The value of H can be obtained according to experiments. The value of H in this embodiment is thirty meters, that is, the maximum distance that the chip liquid sprayed by the flushing end 54 can flush the waste chips in the chip removal groove 2 is about thirty meters. L≤H, L=H is selected in this embodiment, that is, the length of the chip removal groove 2 in this embodiment is approximately L, which is about sixty meters. The distance between the outlets of the two flushing ends 54 in the same chip removal groove 2 is about sixty meters. The middle channel 41 is set at the middle position of the two flushing ends 54. Each intermediate channel 41 corresponds to a group of chip removal devices 3 and is connected to the chip removal devices 3 via the guide member 42 , so that the waste chips in the intermediate channel 41 enter the chip removal devices 3 along the guide member 42 .

[0043] When the workpiece is being processed, the waste chips flow into the chip trough 2 along with the chip fluid. When the workpiece is processed, during the chip removal process of the super-large gantry machine tool, the waste chips on the workbench 1 are cleaned into the chip trough 2, and then the chip fluid is transported to the end pipe 53 through the first submersible pump 51, and sprayed into the chip trough 2 through the flushing end 54. The chip fluid flushes the waste chips in the chip trough 2 into the corresponding intermediate channel 41, and enters the corresponding chip removal device 3 through the intermediate channel 41 for chip removal processing. By setting up a group of chip removal devices 3 and two groups of first submersible pumps 51 and the flushing end 54 at the end pipe 53, the waste chips can be flushed from both ends of the chip trough 2 toward the middle, thereby realizing segmented processing of the waste chips in the chip trough 2, and setting the distance between the flushing end 54 and the intermediate channel 41 to ensure that the waste chips can be thoroughly cleaned. The present application realizes segmented cleaning of the waste chips of the super-large gantry machine tool through multi-point flushing of the waste chips, thereby improving the chip removal effect of the super-large gantry machine tool. By using segmented cleaning, the moving distance of waste chips is reduced, waste chips can be cleaned more quickly, and the power of a single pumping equipment can be reduced, which is more energy-saving and environmentally friendly.

[0044] Reference Figure 2 、 Figure 5 The depth of the chip groove 2 gradually increases from both ends to the middle, so that the chip groove 2 presents a structure with a low middle and high ends, so that the chips in the chip groove 2 can flow into the middle channel 41 more easily along with the cutting fluid, thereby improving the convenience of flushing the chips in the chip groove 2.

[0045] Reference Figure 1 、 Figure 3The chip removal device 3 in this embodiment includes a liquid storage tank 31 and a waste chip filter assembly 32. The liquid storage tank 31 is arranged on one side of one of the chip removal grooves 2. The bottom surface of the liquid storage tank 31 is lower than the bottom surface of the intermediate channel 41. The outlet of the guide member 42 is located above the waste chip filter assembly 32. The guide member 42 in this embodiment includes a bottom plate and three side plates. The two oppositely arranged side plates are provided with sieve holes to filter the debris in the chip liquid flowing out of the intermediate channel 41. At the same time, the chip liquid that has not been filtered in time flows into the waste chip filter assembly 32 along the guide member 42. The waste chip filtering assembly 32 in this embodiment includes a chip conveyor 321 and a plurality of filter plates 322. The plurality of filter plates 322 are combined into a rectangular box structure at the bottom of the liquid storage tank 31. The bottom end of the chip conveyor 321 is arranged in the box structure composed of the filter plates 322. The outlet end of the chip conveyor 321 extends out of the liquid storage tank 31. The filter plates 322 block the debris in the chip liquid in the box structure. The mesh of the filter plate 322 can adopt an aperture of 5mm, 4mm or 3mm. The filtered chip liquid seeps out from the mesh of the filter plate 322 into the liquid storage tank 31, and the chip conveyor 321 discharges the debris in the box structure.

[0046] Reference Figure 3 、 Figure 6 The workbench 1 is provided with a second flushing structure 6. In this embodiment, there are two sets of second flushing structures 6, each corresponding to one intermediate channel 41. The second flushing structure 6 includes a second submersible pump 61 and a second pipe 62. The second pipe 62 is connected to the second submersible pump 61. The outlet end of the second pipe 62 is inserted into the intermediate channel 41 from the end of the intermediate channel 41 away from the flow guide 42, so that the chip liquid ejected from the second pipe 62 flushes the debris in the intermediate channel 41 into the flow guide 42. The depth of the intermediate channel 41 gradually increases from the inlet side to the outlet side, so that the intermediate channel 41 presents a structure with the outlet end of the second pipe 62 higher and the end of the flow guide 42 lower. This facilitates the chip liquid ejected from the second pipe 62 to flush the debris in the intermediate channel 41 into the flow guide 42, improving the convenience of cleaning the debris in the intermediate channel 41.

[0047] The first submersible pump 51 and the second submersible pump 61 are arranged at the bottom of the liquid storage tank 31, and the chip liquid in the liquid storage tank 31 is circulated in stages to flush the chips in the chip removal trough 2 and the intermediate channel 41, realizing the recycling of the chip liquid, reducing resource waste, and reducing chip removal costs. At the same time, it ensures that the second flushing structure 6 has a stable supply of chip liquid to flush the waste chips. The liquid flow rate of each of the four flushing ends 54 is 18L / s. The intermittent opening method is adopted, and 1-2 flushing ends 54 are opened each time to flush the chips in the chip removal trough 2. This avoids the chip liquid in the liquid storage tank 31 from being consumed too quickly and the chip liquid supply being insufficient, thereby ensuring a stable supply of chip liquid. After the flushing of the four flushing ends 54 is completed, the two second submersible pumps 61 are turned on. The second submersible pumps 61 flush the chips in the intermediate channel 41 through the second pipe 62, and the liquid flow rate of each second pipe 62 is 18L / s.

[0048] The implementation principle of Example 1 is as follows: during the chip removal process of the super-large gantry machine tool, the waste chips on the workbench 1 are cleaned into the chip removal groove 2, and then the waste chips are flushed into the corresponding intermediate channel 41 by the chip liquid sprayed by the first submersible pump 51 through the flushing end 54, and the chip liquid sprayed through the outlet of the second pipe 62 flushes the debris in the intermediate channel 41 into the guide member 42, and then is guided to the corresponding chip removal device 3 through the guide member 42 for chip removal processing. By setting a group of chip removal devices 3 and two groups of first submersible pumps 51 and flushing ends 54, the waste chips can be flushed from both ends of the chip removal groove 2 toward the middle, so that the waste chips in the chip removal groove 2 can be processed in sections, and the distance between the flushing end 54 and the intermediate channel 41 is set to ensure that the waste chips can be thoroughly cleaned. This application realizes the segmented cleaning of the waste chips of the super-large gantry machine tool through multi-point flushing of the waste chips, thereby improving the chip removal effect of the super-large gantry machine tool. By using segmented cleaning, the moving distance of waste chips is reduced, waste chips can be cleaned more quickly, and the power of pumping equipment can be reduced, which is more energy-saving and environmentally friendly.

[0049] Example 2 Reference Figure 7The difference between this embodiment and embodiment 1 is that N=2 in this embodiment, that is, the number of chip removal devices 3 and intermediate channels 41 is two, and the corresponding flushing ends 54 are provided in three groups. The length of the chip removal trough 2 in this application is about L, that is, ninety meters. The two groups of intermediate channels 41 are thirty meters apart, and the chip removal devices 3 are provided corresponding to the intermediate channels 41, wherein two groups of flushing ends 54 are provided on both sides of one group of intermediate channels 41, and the distance between the two groups of flushing ends 54 and the intermediate channels 41 is thirty meters, and the flushing ends 54 face the corresponding intermediate channels 41, and another group of flushing ends 54 is provided at the end of the chip removal trough 2, and the flushing end 54 faces the adjacent intermediate channel 41. The two liquid storage tanks 31 are connected by an overflow channel 11, so that the chip liquid in the two liquid storage tanks 31 can flow to each other, keeping the chip liquid in the two liquid storage tanks 31 sufficient.

[0050] Example 3 Reference Figure 8 、 Figure 9 The difference between this embodiment and embodiment 1 is that the end tube 53 in this embodiment is an L-shaped tube, so that the flushing end 54 of the end tube 53 is arranged perpendicular to the inlet end, and a control groove 71 corresponding to the end tube 53 is opened on the workbench 1. The control groove 71 is arranged on the side of the chip groove 2. The end tube 53 is passed through the part of the workbench 1 between the control groove 71 and the chip groove 2, and is rotatably connected to the workbench 1 so that the flushing end 54 rotates in the vertical plane.

[0051] Reference Figure 9 、 Figure 10 The first pipe 52 and the end pipe 53 are connected at one end of the control groove 71 through a main pipe 72. The main pipe 72 is fixedly connected to the first pipe 52 and rotatably connected to the end pipe 53 through a rotary joint 73. The workbench 1 is provided with a drive assembly 74 for driving the end pipe 53 to rotate. In this embodiment, the drive assembly 74 includes a counterweight float 741 and a transmission member 742. The counterweight float 741 is located in the control groove 71. The upward and downward movement path of the counterweight float 741 is located on one side of the main pipe 72 and the end pipe 53, which are arranged in the control groove 71. This prevents the counterweight float 741 from sliding up and down and interfering with the main pipe 72. The opposite side walls of the control groove 71 are provided with guide grooves 743 arranged in the vertical direction. The counterweight float 741 is fixedly provided with a guide block 744 inserted into the guide groove 743. The guide block 744 can slide along the guide groove 743 to guide the movement of the counterweight float 741, thereby improving the stability of the upward and downward movement of the counterweight float 741.

[0052] Reference Figure 9 、 Figure 10In this embodiment, the transmission member 742 comprises a rack 7421 and a gear 7422. The gear 7422 is coaxially fixed to one end of the end pipe 53 located in the control groove 71. The rack 7421 is vertically fixed to the counterweight floating plate 741. The rack 7421 meshes with the gear 7422, causing the counterweight floating plate 741 to move up and down. The rack 7421 drives the gear 7422 to rotate, thereby driving the end pipe 53 to rotate. The main pipe 72 is connected to the control groove 71 via a branch pipe 745. A first control valve 75 is provided at the intersection of the main pipe 72 and the branch pipe 745. The first control valve 75 is an electric two-position three-way valve. When the first control valve 75 controls the main pipe 72 to establish a passage, the main pipe 72 and the branch pipe 745 are disconnected. When the main pipe 72 is disconnected, a passage is established between the main pipe 72 and the branch pipe 745, allowing the main pipe 72 to supply cutting fluid to the control groove 71 through the branch pipe 745 and to the end pipe 53 through the main pipe 72. The control groove 71 is connected to the chip discharge groove 2 through a drainage pipe 76. A second control valve 77 is provided on the drainage pipe 76. The second control valve 77 is an electric control valve that controls the on-off of the drainage pipe 76 and controls the opening degree of the drainage pipe 76.

[0053] The working principle of Example 3 is as follows: when the chips in the chip flute 2 are not being cleaned, the main pipe 72 and the branch pipe 745 are disconnected, the control tank 71 is filled with chip liquid, the counterweight float 741 is at the highest point, and the flushing end 54 on the end pipe 53 is vertically directed toward the bottom wall of the chip flute 2. When cleaning the chips in the chip flute 2, the first submersible pump 51 supplies chip liquid to the end pipe 53 through the first pipe 52. The chip liquid is flushed toward the chip flute 2 through the flushing end 54, flushing the chips in the flushing blind area below the end pipe 53, thereby more thoroughly cleaning the chips in the chip flute 2.

[0054] Then the second control valve 77 is controlled to open the drain pipe 76, the chip liquid in the control groove 71 is continuously reduced, the counterweight float 741 gradually drops, and the end pipe 53 is driven to rotate through the rack 7421, so that the flushing end 54 gradually flips upward, thereby adjusting the direction of the flushing end 54. During the process of the flushing end 54 flipping upward, the chip liquid sprayed from the flushing end 54 is thrown farther and farther in the horizontal direction, and finally reaches the final position when the flushing end 54 is tilted upward and the angle between it and the horizontal plane is 10°. At this time, the chip liquid has not been sprayed out of the chip groove 2, and the horizontal distance of the chip liquid has reached the farthest point. On the one hand, during the flipping of the flushing end 54, the chip liquid flushes the chips in the chip groove 2 toward the middle channel 41. On the other hand, the horizontal throwing distance of the chip liquid increases, which can increase the impact of the chip liquid on the chips, thereby improving the cleaning effect of the chips in the chip groove 2.

[0055] After flushing the chip flute 2, the first control valve 75 is controlled to disconnect the main pipe 72, connecting the main pipe 72 to the branch pipe 745. The second control valve 77 is controlled to close the drain pipe 76, and the first flushing structure 5 discharges the chip liquid into the control tank 71. The counterweight float 741 gradually rises, driving the end pipe 53 to reverse, so that the flushing end 54 is reset, facilitating further flushing of the chip flute 2. By controlling the flow direction of the chip liquid by the first control valve 75 and the second control valve 77, the direction of the flushing end 54 can be adjusted.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
