[0020] A method for using a guide rail drilling device, based on the guide rail drilling device,

[0021] When drilling a hole on the guide rail, the following steps are included: starting the driving assembly to reduce the distance between the two support rods, the support rods push the table plate to flip upward to a horizontal state, using the fixed clamp and the movable clamp to clamp the guide rail, starting the moving mechanism to adjust the position of the drilling mechanism, starting the drilling mechanism to drill a hole on the guide rail, and the coolant in the coolant pipeline cools the guide rail.

[0022] When drilling is completed on the guide rail, the following steps are included: removing the guide rail with the completed drilling from between the fixed fixture and the movable fixture, using the driving assembly to increase the distance between the two support rods, when the two support rods are both located on the side of the two table plates away from each other, the two table plates are flipped downward and opened, the moving mechanism is started to drive the coolant pipe to move, and the coolant in the coolant pipe is used to flush the metal debris on the table plate, the metal debris and coolant on the table plate slide onto the filtering structure for filtration, and the filtered coolant is received by the receiving structure.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. When the two plates are flipped downward, the metal debris and coolant left on the plates can slide down the surface of the plates to the filter structure for filtration, and the filtered coolant can fall into the receiving structure for collection. At the same time, the moving mechanism can drive the coolant pipe to move, and the coolant in the coolant pipe can further flush the metal debris left on the plates. The flushed metal debris slides down along the flipped plates to the filter structure. Therefore, when cleaning and flushing the plates, the plates are facing downward, which can reduce the residual metal debris and improve the cleaning effect of the plates.

[0025] 2. When the support mechanism drives the two tabletops to open, the driving component in the support mechanism drives the two support rods to move away from each other. When the two support rods are located on the side of the two tabletops away from each other, the tabletops flip downward under their own gravity. Therefore, the flipping and opening action of the tabletop is not gradual, but quickly flipped and opened in a short time, so that the metal debris on the tabletop is thrown by the tabletop, which further facilitates the metal debris to leave the tabletop, which is beneficial to further improve the cleaning effect of the tabletop.

[0026] 3. By adding a purge mechanism, when the table is opened, the lifting rod in the drive assembly pushes the drive seat upward, which not only drives the two support rods away from each other, but also drives the piston upward to push the air in the air box out of the air outlet. After the table is opened, the metal debris and coolant remaining on the surface of the table will slide onto the filter net under the action of their own gravity. At the same time, the air blown out from the air outlet blows toward the table, which can use the airflow to purge the table, helping the metal debris and coolant remaining on the table to fall, which is conducive to improving the cleaning effect and efficiency of the table.

[0027] 4. By adding a purge mechanism, the filter can be opened after the table is opened, so the air blown out from the air outlet can also blow to the filter, accelerating the coolant on the surface of the metal debris to pass through the filter, accelerating the drainage, and helping to improve the filtering efficiency.

[0028] 5. The purge mechanism can cooperate with the opening and closing action of the table to achieve linkage. When the table is opened, the purge mechanism performs the purge action; when the table is closed, the purge mechanism replenishes air for the next purge, which is beneficial to improve the action response speed. And there is no need to add other power sources, which is beneficial to saving energy.

[0029] 6. By setting up an elastic structure, when the two worktables are opened, the two worktables flip downward, and the flipped worktables touch the elastic structure. The elastic structure can mitigate the impact of the worktables and prevent the worktables from directly hitting the inner wall of the shell, so that the worktables are protected, the risk of failure can be reduced, and the safety of use can be improved.

[0030] 7. After the table top touches the elastic structure, the table top first squeezes the elastic structure, and then the elastic force of the elastic structure pushes the table top in the opposite direction. In the process of the elastic force of the elastic structure being reduced, the table top vibrates. The vibrating table top can shake off the metal debris adhering to the table top, which is beneficial to improve the cleaning effect.

[0031] 8. The setting of the connecting rod and the cleaning brush can follow the movement of the support rod to clean the metal debris intercepted on the surface of the filter screen, avoiding the accumulation of metal debris falling on the surface of the filter screen on the filter screen, and increasing the filter screen's ability to carry metal debris, making it easier to carry the next wave of metal debris sliding off the table.

[0032] 9. Because the cleaning brush can clean the metal debris on the filter, it can prevent the metal debris from clogging the filter, thereby ensuring the filtering effect of the filter and ensuring the reliability and stability of the filtering operation.

[0033] 10. Because the cleaning brush can sweep the metal debris on the filter screen into the receiving tank for accumulation, it is convenient to collect the metal debris.

[0034] 11. Because the cleaning brush cleans the filter following the movement of the support rod, there is no need to add other power sources, which is beneficial to energy saving.

[0035] 12. By using a telescopic structure as a connecting rod and adding a guiding mechanism, the height of the cleaning brush can adapt to the opening and closing rules of the table. When the table flips down and opens, the cleaning brush sweeps the metal debris intercepted by the filter net last time into the receiving slot. The metal debris intercepted last time has been fully drained, and the dryness of the metal debris has been improved, which is convenient for cleaning; after the table is opened, the filter net can receive the metal debris that falls this time; when the table flips up, the height of the cleaning brush first rises and then falls to the top of the middle of the filter net, so that the cleaning brush will not touch the metal debris that falls on the filter net this time, and will not sweep the metal debris on the filter net to the middle of the filter net, so as to avoid the accumulation of metal debris to block the filter holes and reduce the filtration efficiency.

[0036] 13. The setting of the first limiting structure and the second limiting structure can ensure that the cleaning brush slides along the horizontal groove, the second inclined groove, and the first inclined groove in sequence, avoiding the cleaning brush from sliding in the opposite direction, thereby improving the reliability of the cleaning brush when sliding.

[0037] 14. By adding a water pump and a water inlet pipe, the coolant collected in the receiving structure can be used to rinse the tabletop, thereby realizing the reuse of the coolant and saving resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] See also Figure 4 , Figure 5 and Figure 6 The housing 51 is provided with a supporting mechanism, which is used to drive the two platforms 52 to flip downward to open and flip upward to return to a horizontal state. Figure 5The support mechanism includes two support rods 61, and the two support rods 61 are slidably matched with the horizontal long holes 511 located at the upper part of the shell 51, and one support rod 61 is used to support a table 52.

The coolant pipe 41 has a sufficient length to adapt to the position change of the Y-axis moving seat 27. When the water pump 42 is started, the water pump 42 transports the coolant in the receiving groove 44 to the position of the cutter head 32 through the coolant pipe 41 to cool the cutter head 32 and the drilling position of the guide rail 10. Furthermore, in order to strengthen the spraying force of the coolant, a nozzle can be installed on the coolant pipe 41.

[0082] The working principle of this embodiment 1 is as follows:

[0083] (1) When drilling a hole on the guide rail 10, the method includes the following steps:

[0084] S101, start the driving assembly to reduce the distance between the two support rods 61, and the two support rods 61 push the two platform plates 52 to flip upwards. When the two platform plates 52 are flipped to a horizontal state, shut down the driving assembly.

[0085] S102 , clamp the guide rail 10 using a fixed clamp and a movable clamp.

[0086] S103, start the moving mechanism, the drilling mechanism and the water pump 42; the Y-axis moving module in the moving mechanism drives the cutter head 32 of the drilling mechanism to move to just above the guide rail 10; the cutter head 32 of the drilling mechanism rotates, and the Z-axis moving module drives the cutter head 32 to feed downward. After the current drilling is completed, the Z-axis moving module drives the cutter head 32 to move up and away from the guide rail 10; then the X-axis moving module drives the drilling mechanism to move along the long side direction of the guide rail 10, and continues to drill the next position of the guide rail 10; during the drilling operation, the coolant in the coolant pipe 41 flows to the cutter head 32 and the guide rail 10 for cooling.

[0087] (2) When drilling is completed on the guide rail 10, the method of use includes the following steps:

[0088] S201, start the movable fixture to leave the fixed fixture, so that the fixed fixture and the movable fixture release the guide rail 10, and take the guide rail 10 away.

[0089] S202, start the driving assembly to increase the distance between the two support rods 61. When the two support rods 61 are located on the side of the two platens 52 away from each other, the two platens 52 flip downward and open under the action of their own gravity. The metal debris and coolant remaining on the platens 52 slide along the upper surface of the platens 52 to the filter screen 71 for filtration, and the filtered coolant is received by the receiving groove 44.

[0090] S203, start the water pump 42 and the moving mechanism, the water pump 42 allows the coolant in the receiving groove 44 to flow to the top of the table 52 through the coolant pipe 41, so as to flush the metal debris remaining on the table 52; the X-axis moving module in the moving mechanism drives the coolant pipe 41 to move along the X-axis direction, so that the coolant flushes the surface of the table 52 from the X-axis direction; the Y-axis moving module in the moving mechanism drives the coolant pipe 41 to move along the Y-axis direction, so that the coolant flushes the surface of the table 52 from the Y-axis direction.

[0091] According to the above working principle, it can be seen that the present embodiment 1 has the following effects:

[0092] First, when the two plates 52 are flipped downward and opened, the metal debris and coolant left on the plates 52 can slide along the surface of the plates 52 to the filter structure for filtration, and the filtered coolant can fall into the receiving structure for collection. At the same time, the moving mechanism can drive the coolant pipe 41 to move, and the coolant in the coolant pipe 41 can further flush the metal debris remaining on the plates 52. The flushed metal debris slides along the flipped plates 52 to the filter structure. Therefore, when cleaning and flushing the plates 52, the plates 52 are in a downward state, which can reduce the residual metal debris and improve the cleaning effect of the plates 52.

[0093] Second, when the support mechanism drives the two table plates 52 to open, it is the driving component in the support mechanism that drives the two support rods 61 to move away from each other. When the two support rods 61 are located on the side of the two table plates 52 away from each other, the table plates 52 will flip downward under their own gravity. Therefore, the flipping and opening action of the table plate 52 is not gradual, but quickly flipped and opened in a short time, so that the metal debris on the table plate 52 is thrown by the table plate 52, which further facilitates the metal debris to leave the table plate 52, which is beneficial to further improve the cleaning effect of the table plate 52.

[0094] Third, when flushing the table plate 52, the coolant collected in the receiving structure can be used for flushing, thereby realizing the reuse of the coolant and being beneficial to saving resources.

[0095] Embodiment 2:

[0096] This embodiment 2 is further improved on the basis of embodiment 1: this embodiment 2 also includes a purge mechanism. Figure 8 and Fig. 9 The purge mechanism includes an air box 81, a piston 82 and a piston rod 83. The air box 81 is fixedly mounted on the upper part of the housing 51, and the side wall of the air box 81 is provided with an air outlet 811, and the air outlet 811 faces the platen 52. The interior of the air box 81 is provided with a piston 82, and the piston 82 is vertically slidably matched with the air box 81. The bottom of the piston 82 is fixedly mounted with a piston rod 83, and the bottom of the piston rod 83 is fixedly mounted on the drive seat 63.

[0097] The working principle of this embodiment 2 is as follows:

[0098] (1) When opening the two platform plates 52, the output end of the lifting rod 62 pushes the driving seat 63 upward. On the one hand, the driving seat 63 pushes the lower ends of the two driving rods 64 upward, so that the angle between the two driving rods 64 increases. The two driving rods 64 push the two support rods 61 away from each other, so that the distance between the two support rods 61 increases. When the distance between the two support rods 61 is the largest, the two support rods 61 are both located on the side of the two platform plates 52 away from each other. The two platform plates 52 are not supported by the support rods 61, and the two platform plates 52 flip downward to open; on the other hand, the driving seat 63 pushes the piston rod 83 upward, and the piston rod 83 pushes the piston 82 upward. The piston 82 pushes the air in the air box 81 out of the air outlet 811, and the air pushed out from the air outlet 811 blows toward the platform plate 52.

[0099] (2) When closing the two platform plates 52, the output end of the lifting rod 62 drives the driving seat 63 to move downward. On the one hand, the driving seat 63 drives the lower ends of the two driving rods 64 to move downward, so that the angle between the two driving rods 64 decreases, and the two driving rods 64 drive the two support rods 61 to move closer to each other, so that the distance between the two support rods 61 decreases, and the two support rods 61 push the two platform plates 52 to flip upward and return to a horizontal state, so that the two platform plates 52 are closed; on the other hand, the driving seat 63 drives the piston rod 83 to move downward, and the piston rod 83 drives the piston 82 to move downward, so that the internal space of the air box 81 increases, the internal air pressure of the air box 81 decreases, and the outside air enters the interior of the air box 81 through the air outlet 811.

[0100] According to the above working principle, it can be seen that the second embodiment can bring the following effects by adding a purge mechanism:

[0101] First, after opening the table 52, the metal debris and coolant remaining on the surface of the table 52 will slide onto the filter 71 under the action of their own gravity. At the same time, the air blown out from the air outlet 811 blows toward the table 52, and the airflow can be used to sweep the table 52, helping the metal debris and coolant remaining on the table 52 to fall, which is beneficial to improving the cleaning effect and cleaning efficiency of the table 52.

[0102] Second, after the table 52 is opened, the filter 71 can be opened, so the air blown out from the air outlet 811 can also be blown toward the filter 71, accelerating the coolant on the surface of the metal debris to pass through the filter 71, accelerating the drainage, and helping to improve the filtering efficiency.

[0103] Third, when the table 52 is opened, the lifting rod 62 in the driving assembly pushes the driving seat 63 to move upward, and the driving seat 63 not only drives the two support rods 61 away from each other, but also drives the piston 82 to move upward, and pushes the air in the air box 81 out from the air outlet 811; when the table 52 is closed, the lifting rod 62 in the driving assembly drives the driving seat 63 to move downward, and the driving seat 63 not only drives the two support rods 61 closer to each other, but also drives the piston 82 to move downward, so that the air pressure in the air box 81 is reduced, and the outside air can enter the air box 81 through the air outlet 811 to achieve air replenishment. Therefore, the purge mechanism can cooperate with the opening and closing action of the table 52 to achieve linkage and improve the action response speed. And there is no need to add other power sources, which is conducive to energy saving.

[0104] Embodiment 3:

[0105] This embodiment 3 is further improved on the basis of embodiment 1: Fig.10 The inner wall of the shell 51 is provided with an elastic structure, and the elastic structure can adopt a first spring 512. One end of the first spring 512 is fixedly installed on the inner wall of the shell 51, and the other end of the first spring 512 is suspended.

[0106] The working principle of this embodiment 3 is as follows:

[0107] When the two platform plates 52 are opened, the two platform plates 52 flip downward, and the flipped platform plates 52 touch the suspended end of the first spring 512. The first spring 512 can mitigate the impact of the platform plates 52 and prevent the platform plates 52 from directly hitting the inner wall of the shell 51, so that the platform plates 52 are protected, the risk of failure is reduced, and the safety of use is improved.

[0108] After the table plate 52 touches the first spring 512, the table plate 52 first squeezes the first spring 512, and then the elastic force of the first spring 512 pushes the table plate 52 in the reverse direction. In the process of the elastic force of the first spring 512 being reduced, the table plate 52 vibrates. The vibrating table plate 52 can shake off metal debris adhering to the table plate 52, which is beneficial to improving the cleaning effect.

[0109] Embodiment 4:

[0110] This embodiment 4 is further improved on the basis of embodiment 1: Fig.11 The filtering structure also includes receiving slots 72 located on both sides of the filter screen 71. A support plate 513 is fixedly installed inside the housing 51, and the receiving slots 72 are placed on the support plate 513. Figure 3 A cleaning hole 514 is provided on the side wall of the shell 51 , and a worker can pull out the receiving slot 72 placed on the support plate 513 from the cleaning hole 514 , or the worker can push the receiving slot 72 onto the support plate 513 from the cleaning hole 514 .

[0111] See also Fig.10 and Fig.14 The support mechanism also includes a connecting rod 73 and a cleaning brush 74. The support rod 61 is connected to the cleaning brush 74 through the connecting rod 73. The cleaning brush 74 is used to sweep the metal debris trapped on the surface of the filter screen 71 into the receiving groove 72, and the receiving groove 72 can collect the metal debris.

[0112] See also Figure 8 The support plate 513 is tilted, and the receiving slot 72 placed on the support plate 513 is also tilted, so that the metal debris received in the receiving slot 72 can slide down along the tilted direction, making it convenient for the metal debris to accumulate at the lower position of the receiving slot 72. Therefore, when cleaning the receiving slot 72, there is no need to completely pull the receiving slot 72 out of the cleaning hole 514. You only need to pull out the lower part of the receiving slot 72 and dig out the metal debris accumulated at the lower part of the receiving slot 72.

[0113] The working principle of this embodiment 4 is as follows:

[0114] (1) When the two platform plates 52 are opened, the output end of the lifting rod 62 pushes the driving seat 63 upward, and the driving seat 63 pushes the lower ends of the two driving rods 64 to move upward, so that the angle between the two driving rods 64 increases. The two driving rods 64 push the two support rods 61 away from each other. During this process, the support rod 61 drives the connecting rod 73 and the cleaning brush 74 to move together, and the cleaning brush 74 sweeps the metal debris trapped on the filter screen 71 into the receiving grooves 72 located on both sides of the filter screen 71.

[0115] When the distance between the two support rods 61 is the largest, the two support rods 61 are both located on the side of the two platens 52 away from each other, the two platens 52 are not supported by the support rods 61, the two platens 52 are flipped downward and opened, and at this time, the connecting rod 73 and the cleaning brush 74 are both located above the receiving groove 72.

[0116] (2) When the two platform plates 52 are closed, the output end of the lifting rod 62 drives the driving seat 63 to move downward, and the driving seat 63 drives the lower ends of the two driving rods 64 to move downward, so that the angle between the two driving rods 64 decreases, and the two driving rods 64 drive the two supporting rods 61 to move closer to each other. During this process, the supporting rod 61 drives the connecting rod 73 and the cleaning brush 74 to move together, and the cleaning brush 74 returns to the upper middle part of the filter screen 71.

[0117] According to the above working principle, it can be seen that this embodiment 4 has the following effects:

[0118] First, the connection rod 73 and the cleaning brush 74 can follow the movement of the support rod 61 to clean the metal debris intercepted on the surface of the filter 71, thereby preventing the metal debris that falls on the surface of the filter 71 from accumulating on the filter 71. This can increase the filter 71's ability to carry metal debris, making it easier to carry the next wave of metal debris that slides down from the table 52.

[0119] Second, because the cleaning brush 74 can clean the metal debris on the filter 71, it can prevent the metal debris from clogging the filter 71, thereby ensuring the filtering effect of the filter 71 and ensuring the reliability and stability of the filtering operation.

[0120] Third, because the cleaning brush 74 can sweep the metal debris on the filter screen 71 into the receiving groove 72 for accumulation, it is convenient to collect the metal debris.

[0121] Fourthly, because the action of the cleaning brush 74 to clean the filter screen 71 follows the action of the support rod 61, there is no need to add other power sources, which is conducive to energy saving.

[0122] Embodiment 5:

[0123] This embodiment 5 is further improved on the basis of embodiment 4: Fig.14 The connecting rod 73 adopts a telescopic structure, which includes a sliding sleeve 731 and a sliding rod 732. The top of the sliding sleeve 731 is fixedly installed on the bottom of the support rod 61. The sliding rod 732 is provided inside the sliding sleeve 731. The sliding sleeve 731 and the sliding rod 732 are vertically slidably matched. The bottom of the sliding rod 732 is fixedly installed on the top of the cleaning brush 74.

[0124] This embodiment 5 also includes a guiding mechanism, see Fig.11 and Fig.12 The guide mechanism includes a guide channel provided on the inner side wall of the housing 51, and the guide channel includes a horizontal groove 91, a first inclined groove 92, and a second inclined groove 93. The lower end of the first inclined groove 92 is connected to one end of the horizontal groove 91, the lower end of the second inclined groove 93 is connected to the other end of the horizontal groove 91, and the upper end of the first inclined groove 92 is connected to the upper end of the second inclined groove 93. A guide pin 741 is fixedly mounted on the end of the cleaning brush 74, and the guide pin 741 is slidably matched with the guide channel.

[0125] See also Fig.12 The guiding mechanism further includes a first limiting structure and a second limiting structure, wherein the first limiting structure is disposed at the lower end of the first inclined slot 92. The horizontal slot 91 is provided with a second limiting structure at one end close to the second inclined slot 93.

[0126] See also Fig.12The first limiting structure includes a first receiving groove 94, a first wedge block 95 and a first elastic member. The first receiving groove 94 is provided on the inner side wall of the housing 51, and the first receiving groove 94 is connected to the lower end of the first inclined groove 92. A first wedge block 95 and a first elastic member are provided in the first receiving groove 94. The first elastic member is used to push the first wedge block 95 out of the first receiving groove 94, and the first elastic member can be a second spring 96. A first guide shaft 941 is fixedly mounted on the groove wall of the first receiving groove 94, and the second spring 96 is sleeved on the first guide shaft 941. A first shaft hole is provided inside the first wedge block 95, and the first guide shaft 941 is slidably matched with the first shaft hole.

[0127] See also Fig.12 The second limiting structure includes a second receiving groove 97, a second wedge block 98 and a second elastic member. The second receiving groove 97 is provided on the inner side wall of the housing 51, and the second receiving groove 97 is connected with an end of the horizontal groove 91 close to the second inclined groove 93. A second wedge block 98 and a second elastic member are provided in the second receiving groove 97. The second elastic member is used to push the second wedge block 98 out of the second receiving groove 97, and the second elastic member can be a third spring 99. A second guide shaft 971 is fixedly mounted on the groove wall of the second receiving groove 97, and the third spring 99 is sleeved on the second guide shaft 971. A second shaft hole is provided inside the second wedge block 98, and the second guide shaft 971 is slidably matched with the second shaft hole.

[0128] The working principle of this embodiment 5 is as follows:

[0129] (1) When the two platform plates 52 are opened, the output end of the lifting rod 62 pushes the driving seat 63 upward, and the driving seat 63 pushes the lower ends of the two driving rods 64 to move upward, so that the angle between the two driving rods 64 increases, and the two driving rods 64 push the two support rods 61 away from each other.

[0130] During this process, the support rod 61 drives the connecting rod 73 and the cleaning brush 74 to move together, and the guide pin 741 at the end of the cleaning brush 74 slides in the horizontal groove 91 from the end of the horizontal groove 91 close to the first inclined groove 92 to the end of the horizontal groove 91 close to the second inclined groove 93, so that the cleaning brush 74 sweeps the metal debris on the surface of the filter screen 71 into the receiving groove 72.

[0131] When the distance between the two support rods 61 is the largest, the two support rods 61 are both located on the side of the two platens 52 away from each other, and the two platens 52 are not supported by the support rods 61. The two platens 52 are flipped downward and opened, and the metal debris and coolant on the surface of the platens 52 fall onto the filter screen 71. At this time, the cleaning brush 74 is located above the receiving slot 72.

[0132] At the same time, the guide pin 741 slides from the horizontal slot 91 to the second inclined slot 93. Fig.12When the guide pin 741 contacts the right side wall of the second wedge block 98, the included angle between the moving direction of the guide pin 741 and the right side wall of the second wedge block 98 is an acute angle, so the guide pin 741 has a component force on the second wedge block 98 toward the second receiving groove 97, so that the guide pin 741 can overcome the elastic force of the third spring 99 to push the second wedge block 98 to move the second wedge block 98 toward the inside of the second receiving groove 97. When the second wedge block 98 enters the second receiving groove 97, the horizontal groove 91 is connected with the second inclined groove 93, and the guide pin 741 smoothly enters the arc-shaped connecting position of the second inclined groove 93 and the horizontal groove. After the guide pin 741 enters the lower end of the second inclined groove 93, the second wedge block 98 re-extends out of the second receiving groove 97 under the push of the elastic force of the third spring 99. If the guide pin 741 moves in the opposite direction, because the moving direction of the guide pin 741 is at a right angle to the left side wall of the second wedge block 98, the guide pin 741 cannot push the second wedge block 98 into the second accommodating groove 97, so that the second wedge block 98 prevents the guide pin 741 from moving from the lower end of the second inclined groove 93 to the horizontal groove 91.

[0133] Through the above process, it can be known that the metal debris that has just fallen on the filter screen 71 will not be cleaned up by the cleaning brush 74. The cleaning brush 74 cleans the metal debris that has just fallen on the filter screen 71 when the platen 52 was opened last time, so that the metal debris that has just fallen on the filter screen 71 has sufficient time to drain, reducing the residual coolant, and improving the dryness of the metal debris, making the cleaning brush 74 more convenient and effective when cleaning.

[0134] (2) When the two platform plates 52 are closed, the output end of the lifting rod 62 drives the driving seat 63 to move downward, and the driving seat 63 drives the lower ends of the two driving rods 64 to move downward, so that the angle between the two driving rods 64 decreases, and the two driving rods 64 drive the two support rods 61 to move closer to each other.

[0135] During this process, the support rod 61 drives the connecting rod 73 and the cleaning brush 74 to move together, and the cleaning brush 74 drives the guide pin 741 to move together. Specifically, first, the guide pin 741 slides upward along the second inclined groove 93, so that the height of the cleaning brush 74 rises, and the connecting rod 73 shortens adaptively; then, the guide pin 741 continues to slide from the second inclined groove 93 into the first inclined groove 92, and the guide pin 741 slides down in the first inclined groove 92, so that the height of the cleaning brush 74 decreases, and the connecting rod 73 extends adaptively; finally, the guide pin 741 overcomes the elastic force of the second spring 96 and pushes the first wedge block 95, so that the first wedge block 95 moves toward the inside of the first receiving groove 94 When the first wedge 95 enters the first receiving groove 94, the first inclined groove 92 is connected with the horizontal groove 91, and the guide pin 741 smoothly enters the horizontal groove 91. After the guide pin 741 enters the horizontal groove 91, the height of the cleaning brush 74 drops to the lowest position, and the cleaning brush 74 is located above the middle of the filter screen 71. In addition, the first wedge 95 is pushed by the elastic force of the second spring 96 to extend out of the first receiving groove 94 again, and the first wedge 95 prevents the guide pin 741 from moving from the horizontal groove 91 to the inside of the first inclined groove 92. When the connecting rod 73 is extended and retracted, the sliding rod 732 slides in the vertical direction inside the sliding sleeve 731.

[0136] According to the above working principle, it can be seen that this embodiment 5 has the following effects:

[0137] First, the height of the cleaning brush 74 can adapt to the opening and closing rules of the table 52. When the table 52 is turned down and opened, the cleaning brush 74 sweeps the metal debris intercepted by the filter 71 last time into the receiving slot 72; after the table 52 is opened, the filter 71 can receive the metal debris falling this time; when the table 52 is turned up, the height of the cleaning brush 74 first rises and then falls to the middle of the filter 71, so that the cleaning brush 74 will not contact the metal debris falling on the filter 71 this time, and will not sweep the metal debris on the filter 71 to the middle of the filter 71, so as to avoid the accumulation of metal debris to block the filter holes and reduce the filtering efficiency.

[0138] Second, the setting of the first limiting structure and the second limiting structure can ensure that the cleaning brush 74 slides along the horizontal groove 91, the second inclined groove 93, and the first inclined groove 92 in sequence, avoiding the cleaning brush 74 from sliding in the opposite direction, thereby improving the reliability of the cleaning brush 74 when sliding.

[0139] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
