Description

Technical Field

[0001] This invention relates to the field of dual-station drilling and milling machine technology, and in particular to a dual-station drilling and milling platform for mirror barrel machining. Background Technology

[0002] The microscope tube of an optical instrument is a core supporting component of an optical system. Its precision directly determines the coaxiality, positioning accuracy, and final image quality of optical elements (such as lenses and prisms). It is widely used in microscopes, telescopes, camera lenses, industrial inspection equipment, and medical imaging equipment (such as endoscopes). In the microscope tube manufacturing process, drilling and milling are key processes. A system of holes (such as threaded holes, apertures, and stepped holes) needs to be machined on the tube wall for positioning, connection, ventilation, or optical path adjustment. As optical instruments develop towards "high precision, miniaturization, and integration," the technical challenges of microscope tube drilling are constantly escalating.

[0003] However, in existing technologies, existing CNC drilling and milling machines generally have T-slot worktables installed in their machining areas. The T-slot worktables facilitate the installation and fixation of various fixtures and workpieces in the CNC machine tool's machining area, which is beneficial for the stable machining of workpieces by the CNC drilling and milling machine. However, when the CNC drilling and milling machine is machining workpieces, machining chips are generated. These chips fall into the slots of the T-slot worktable. After machining, in order to prevent the chips from hindering the normal use of the T-slot worktable, it is generally necessary for the operator to remove and clean them. However, these slots are generally quite narrow and numerous, making it difficult for the operator to remove and clean them, resulting in low chip removal efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a dual-station drilling and milling platform for mirror barrel machining to address the current problems of high difficulty and low efficiency in T-slot chip removal and cleaning.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A dual-station drilling and milling platform for mirror barrel machining includes:

[0007] A frame is provided with a worktable. The worktable has multiple parallel T-slots that allow T-bolts to pass through. Two clamps are provided on the worktable, distributed on the left and right. The two clamps are fixed to the worktable by passing T-bolts through the T-slots.

[0008] A water spray plate is installed on the inner wall of a T-shaped groove. The length of the water spray plate is the same as the length of the T-shaped groove. Multiple sets of water spray nozzles are symmetrically arranged on the water spray plate about the midpoint. Each set of water spray nozzles includes a first outlet and a second outlet. The first outlet on the left side of the midpoint of the water spray plate faces the left end of the T-shaped groove, and the second outlet on the left side of the midpoint of the water spray plate faces the right end of the T-shaped groove.

[0009] A control component is provided to adjust the opening and closing of the first and second water outlets of multiple sets of spray nozzles, thereby adjusting the amount of water flowing towards both ends in the T-shaped groove. The amount of water is positively correlated with the length of the chip removal path of the T-shaped groove.

[0010] Furthermore, the control component includes a first sealing plate and a second sealing plate. The first sealing plate is slidably and sealingly disposed on the first water outlet, and the second sealing plate is slidably and sealingly disposed on the second water outlet. When the T-bolt enters the T-groove, it can rub against the first sealing plate and the second sealing plate. The first sealing plate and the second sealing plate are configured such that when the T-bolt has not passed the midpoint of the spray plate, the first sealing plate opens the first water outlet and the second sealing plate blocks the second water outlet. After the T-bolt passes the midpoint of the spray plate, the first sealing plate blocks the first water outlet and the second sealing plate opens the second water outlet.

[0011] Furthermore, the diameter of the second outlet is larger than that of the first outlet.

[0012] Furthermore, the acute angle formed between the first outlet and the T-slot is greater than the acute angle formed between the second outlet and the T-slot.

[0013] Furthermore, the spray plate has a connecting hole, and a bolt is connected to the connecting hole.

[0014] Furthermore, the water spray plates are provided on both inner sidewalls of the T-shaped groove.

[0015] Furthermore, a water tank is provided on the workbench, and a water supply pipe is provided on the water tank, which is connected to the interior of the water spray plate.

[0016] Furthermore, a water pump is installed on the water tank, the water pump is connected to one end of the water supply pipe, and the other end of the water supply pipe is connected to the inside of the spray plate.

[0017] Furthermore, a drainage trough is provided on the workbench, and the drainage trough is connected to both ends of the T-shaped groove.

[0018] Furthermore, the fixture includes a body, a positioning block, a clamping block, and a locking bolt. The positioning block is fixedly disposed on the top of the body and has a positioning groove. The locking bolt is threaded through the side wall of the body and extends into the positioning groove. One end of the locking bolt located in the positioning groove is connected to the clamping block.

[0019] The beneficial effects of this invention are:

[0020] This invention features a water spray plate installed within a T-slot. Multiple sets of spray nozzles are symmetrically arranged about the midpoint of the spray plate. Each set of nozzles includes a first outlet and a second outlet. The first outlet faces both ends of the T-slot, and the second outlet faces the middle. Without the fixture installed, water can drain from the middle of the T-slot to both sides, shortening the chip removal path. A control component is also included. After the fixture is installed, the control component adjusts the water volume within the T-slot according to the length of the chip removal path. A longer chip removal path requires a larger water volume, significantly reducing water flow attenuation, eliminating dead zones and accumulation of debris, and improving chip removal efficiency. A shorter chip removal path requires less water, saving resources.

[0021] This invention features a first sealing plate at the first water outlet and a second sealing plate at the second water outlet. When a T-bolt enters the T-groove, it can push either the first or second sealing plate to move. Before the clamp is installed, the first sealing plate opens the first water outlet, and the second sealing plate closes the second water outlet, ensuring that the water flows from the middle to both sides. After the T-bolt passes the midpoint of the spray plate, it will push the first sealing plate to close the first water outlet and push the second sealing plate to open the second water outlet, thereby increasing the water volume of the longer chip removal path and ensuring that the chip removal efficiency is maintained at a high level.

[0022] The present invention sets the diameter of the second water outlet to be larger than that of the first water outlet, so that the second water outlet can replenish more water when replenishing water in a longer chip removal path.

[0023] This invention, by setting a second water outlet with a gentle angle, allows the water flow to adhere more closely to the wall and become more concentrated, forming a continuous water film that can carry away small debris from the bottom, walls, and corners of the tank, thus improving the quality of debris removal.

[0024] This invention improves chip removal efficiency by installing two water spray plates inside a T-slot, with the two spray plates located on the two inner side walls of the T-slot respectively, and the two spray plates working simultaneously. Attached Figure Description

[0046] The following reference Figures 1-14 This invention describes a dual-station drilling and milling platform for mirror barrel machining.

[0047] A dual-station drilling and milling platform for mirror barrel machining is provided. It includes a frame 100, on which a drilling and milling head 110 is mounted for drilling and milling mirror barrel workpieces. A worktable 120 is mounted on the frame 100, with multiple parallel T-slots 200. T-bolts can pass through the T-slots 200. Two clamps 300 are mounted on the worktable 120 to hold the mirror barrel workpieces. The two clamps 300 are fixed to the worktable 120 by T-bolts inserted into the T-slots 200 and connected to the clamps 300. The two clamps 300 are distributed horizontally on the worktable 120, with each end of one clamp occupying a T-slot 200. The T-slots occupied by the two clamps 300 do not overlap, thus avoiding interference with the movement of debris within the T-slots 200. To facilitate debris discharge, a water spray plate 210 is provided on the side wall of the T-slot 200. The water spray plate 210 is hollow and allows water to pass through. The length of the water spray plate 210 is the same as the length of the T-slot 200. Multiple sets of water spray nozzles 220 are symmetrically arranged on the water spray plate 210 about the midpoint. Each set of water spray nozzles 220 includes a first water outlet 221 and a second water outlet 222. The first water outlet 221 is located to the left of the midpoint of the water spray plate 210. The first water outlet 221, located to the right of the midpoint of the spray plate 210, faces the left end of the T-slot 200; the second water outlet 222, located to the left of the midpoint of the spray plate 210, faces the right end of the T-slot 200; and the second water outlet 222, located to the right of the midpoint of the spray plate 210, faces the left end of the T-slot 200. When the spray plate 210 is filled with water, water can be discharged from the first water outlet 221 and the second water outlet 222.

[0048] The present invention also includes a control component, which is used to open and close the first outlet 221 and the second outlet 222 of the multiple sets of water nozzles 220, thereby adjusting the amount of water flowing towards both ends within the T-groove 200. The amount of water is positively correlated with the length of the chip removal path inside the T-groove 200; the longer the chip removal path, the greater the water volume, and the shorter the chip removal path, the smaller the water volume. Since the clamp 300 needs to be fixed by T-bolts inserted into the T-groove 200, the T-bolts fixed at both ends of the clamp 300 change the chip removal path of the T-groove 200 after entering the T-groove 200. When the clamp 300 is not installed, that is, when the T-bolts have not entered the T-groove 200, the control component keeps all the first outlets 221 in the open state and all the second outlets 222 in the closed state. When the spray plate 210 starts spraying water, the water flows from the midpoint of the T-groove 200 to both sides. After the fixture 300 is installed, the chip removal path of the T-slot 200 changes. Specifically, when the fixture 300 is installed on the left half of the workbench 120, the chip removal path on the left side of the T-slot 200 is the shortest and the chip removal path on the right side of the T-slot 200 is the longest when the fixture 300 is the center. At this time, the control component opens the multiple second water outlets 222 on the left side of the midpoint of the water spray plate 210 and on the right side of the fixture 300, so that the second water outlets 222 replenish water to the right side of the T-slot 200. The left side of the T-slot 200 has a smaller water volume but the shortest chip removal path, while the right side of the T-slot 200 has a longer drainage path but a larger water volume, thus effectively removing debris. Similarly, when another fixture 300 is installed on the right half of the workbench 120, with the installed fixture 300 as the center, the right side of the T-slot 200 has the shortest chip removal path, while the left side of the T-slot 200 has the longest chip removal path. Therefore, the left side of the T-slot 200 has a larger water volume, while the right side has a smaller water volume.

[0049] Understandably, in existing technologies, when cleaning the T-slot 200, water or gas is typically sprayed from one side of the T-slot 200 to discharge debris from the other end. Because the T-slot 200 is relatively narrow and long, debris tends to remain or accumulate there, with the end furthest from the water or gas spray being more prone to debris buildup. This results in low cleaning efficiency and poor quality. In contrast, this invention sprays water from the middle of the T-slot 200 to both sides, reducing the path by half and improving debris removal efficiency. Furthermore, the spray plate 210 has multiple nozzles 220, ensuring that all areas within the T-slot 200 are impacted by water flow, preventing debris accumulation. Simultaneously, after installing the clamp 300, the longer path is significantly shorter than in existing technologies. Moreover, the longer path of this invention increases the water volume, compensating for the low debris removal efficiency caused by the longer path and ensuring a high level of efficiency.

[0050] Specifically, the control components in this embodiment include a first sealing plate 240 and a second sealing plate 250. The first sealing plate 240 is slidably and sealingly disposed on the first water outlet 221, and the second sealing plate 250 is slidably and sealingly disposed on the second water outlet 222. The water outlet 220 is located at the concave position on the spray plate 210. The first sealing plate 240 and the second sealing plate 250 have overlapping portions, so that the first sealing plate 240 and the second sealing plate 250 just fill the concave position. One end of the first sealing plate 240 and the second sealing plate 250 is flush with the spray plate 210. When the T-bolt slides in the T-slot 200, The outer periphery of the T-bolt can rub against the first sealing plate 240 and the second sealing plate 250, so that when the T-bolt slides in the T-groove 200, it can drive the first sealing plate 240 and the second sealing plate 250 to slide. The first sealing plate 240 and the second sealing plate 250 are configured such that when the T-bolt has not passed the midpoint of the spray plate 210, the first sealing plate 240 opens the first water outlet 221 and the second sealing plate 250 blocks the second water outlet 222; when the T-bolt passes the midpoint of the spray plate 210, the first sealing plate 240 blocks the first water outlet 221 and the second sealing plate 250 opens the second water outlet 222.

[0051] It should be noted that when the two clamps 300 are not installed, the T-bolt does not pass through the midpoint of the spray plate 210. The first sealing plate 240 opens the first outlet 221, and the second sealing plate 250 seals the second outlet 222, as detailed below. Figure 8 As shown, when the spray plate 210 starts spraying water, water can only be discharged from the first outlet 221. The first outlet 221 on the spray plate 210 is symmetrically arranged about the midpoint of the spray plate 210. The first outlet 221 sprays water towards both ends of the T-slot 200, so that the water in the T-slot 200 is discharged from the middle to both ends. For ease of description, the T-bolt on the left side of the clamp 300 is named the first T-bolt 310, and the T-bolt on the right side of the clamp 300 is named the second T-bolt 320. When the two clamps 300 are installed, if the first T-bolt 310 or the second T-bolt 320 passes the midpoint of the spray plate 210, the first T-bolt 310 or the second T-bolt 320 pushes the first sealing plate 240 to block the first outlet 221, and the first T-bolt 310 or the second T-bolt 320 pushes the second sealing plate 250 to open the second outlet 222.

[0052] For example, when the first T-bolt 310 of the left clamp 300 is inserted into the T-slot 200, the first T-bolt 310 moves from left to right. Since the right end of the second sealing plate 250 abuts against the concave position, and the left end of the first sealing plate 240 is restricted, the first sealing plate 240 and the second sealing plate 250 are prevented from being pushed by the first T-bolt 310. Therefore, the left path of the T-slot 200 where the left clamp 300 is located is the shortest. When the second T-bolt 320 of the left clamp 300 is inserted into the T-slot 200, the second T-bolt 320 moves from right to left. The longest path is on the right side of the T-slot 200. Since the spray plates 210 within the T-slot 200 are symmetrically arranged about the midpoint, the T-slot 200 to the right of the midpoint of the spray plate 210 will not affect the opening of the first outlet 221 or the closing of the second outlet 222 when the second T-bolt 320 passes through. After the second T-bolt 320 passes the midpoint of the spray plate 210, it will push the second sealing plate 250 and the first sealing plate 240 to the left, causing the first sealing plate 240 to close the first outlet 221 and the second sealing plate 250 to open the second outlet 222. The specific state is as follows: Figure 14 As shown. Since the second water outlet 222 faces the right end of the T-slot 200, the second water outlet 222 on the left side of the midpoint of the spray plate 210 sprays water towards the right end of the T-slot 200. The first water outlet 221 in the right T-slot 200 also sprays water towards the right end of the T-slot 200. Therefore, the water volume on the right side of the T-slot 200 increases, thereby compensating for the problem of poor chip removal efficiency caused by the longer path on the right side of the T-slot 200. Similarly, when installing the right clamp 300, the operation process is the same as that of installing the left clamp 300. The first T bolt 310 and the second T bolt 320 move in the same direction in the T-slot 200. The difference is that the right clamp 300 is located in the right half of the workbench 120. Therefore, the path of the T-slot 200 on the left side of the first T bolt 310 at both ends of the right clamp 300 is the longest, and the water flow in this longest path is larger, while the path on the right side of the second T bolt 320 is the shortest.

[0053] In a further embodiment, to further increase the water flow rate of the longer section of the T-slot 200, the aperture of the second outlet 222 in this embodiment is larger than that of the first outlet 221, so that most of the water in the spray plate 210 will pass through the second outlet 222, thereby enabling the second outlet 222 to replenish more water to the first outlet 221 on the other side, thus further increasing the water flow rate.

[0054] Specifically, in this embodiment, the acute angle between the first outlet 221 and the T-shaped groove 200 is greater than the acute angle between the second outlet 222 and the T-shaped groove 200, so that when the second outlet 222 replenishes water to the first outlet 221 on the other side, the water flow can better carry debris.

[0055] It should be noted that the smaller angle of the second outlet 222 allows the water flow to be more gentle and concentrated along the inner wall of the T-channel 200, preventing the water flow from being dispersed due to an excessively large angle. This enhances the scouring force of the water flow on the bottom and side walls of the T-channel 200. Compared to the larger acute angle of the first outlet 221, the smaller angle design of the second outlet 222 allows the water flow to adhere closely to the inner wall of the T-channel 200, forming a continuous water film. This film covers a longer path and effectively encapsulates fine debris scattered in various corners of the channel, reducing debris residue in the gaps or corners of the channel wall. Especially in areas with a longer path in the T-channel 200, this small-angle water flow can continuously act on the debris. Combined with the larger flow rate from the larger aperture of the second outlet 222, sufficient scouring intensity is maintained, smoothly pushing the debris towards the end of the T-channel 200 for discharge.

[0056] In a further embodiment, the above-mentioned water spray plates 210 are provided on both side walls of the T-slot 200. The arrangement of the two water spray plates 210 further increases the water volume in the T-slot 200, thereby further improving the discharge efficiency of debris inside the T-slot 200.

[0057] Specifically, in order to facilitate the fixing of the two spray plates 210 to the two inner sidewalls of the T-slot 200, each of the two spray plates 210 in this embodiment is provided with a connecting hole 211, and a bolt (not shown in the figure) is connected in the connecting hole 211. The bolt fixes the two spray plates 210 to the two inner sidewalls of the T-slot 200.

[0058] Specifically, to facilitate the sliding connection of the first sealing plate 240 and the second sealing plate 250, in this embodiment, the first sealing plate 240 is provided with a first connecting block 241, and the second sealing plate 250 is provided with a second connecting block 251. A groove 230 is provided in the recessed position of the spray plate 210. The first connecting block 241 of the first sealing plate 240 is slidably disposed within the groove 230, thereby allowing the first sealing plate 240 to slide. Similarly, the second connecting block 251 of the second sealing plate 250 is also slidably disposed within the groove 230, thereby allowing the second sealing plate 250 to slide as well. The first sealing plate 240 is provided with a first sliding surface 242, and the second sealing plate 250 is provided with a second sliding surface 252. The first sliding surface 242 and the second sliding surface 252... The moving surface 252 is smooth. The first sealing plate 240 and the second sealing plate 250 are slidably connected together through the first sliding surface 242 and the second sliding surface 252. In order to facilitate the first sealing plate 240 and the second sealing plate 250 to be driven by the T-bolt, in this embodiment, the first sealing plate 240 is provided with a first friction surface 243, which is located on the back of the first sliding surface 242. The first friction surface 243 can rub against the T-bolt. The second sealing plate 250 is provided with a second friction surface 253, which faces the same direction as the first friction surface 243. The second friction surface 253 and the first friction surface 243 of the first sealing plate 240 are on the same horizontal plane. The second friction surface 253 can rub against the T-bolt.

[0059] In a further embodiment, in order to enable the water spray plate 210 to spray water, the present invention provides a water tank 130 on the workbench 120, the water tank 130 is filled with a large amount of water, and a water supply pipe 140 is provided on the water tank 130. The water supply pipe 140 is connected to the inside of the water spray plate 210. A water passage hole 141 is opened on the side of the water spray plate 210 facing away from the water nozzle 220. The water passage hole 141 is connected to the water supply pipe 140. The water supply pipe 140 supplies water to the water spray plate 210. The water is discharged from each set of water nozzles 220 on the water spray plate 210 into the T-shaped groove 200, thereby carrying out the debris in the T-shaped groove 200.

[0060] Specifically, a water pump 160 is installed on the water tank 130. The water pump 160 is connected to one end of the water supply pipe 140, and the other end of the water supply pipe 140 is connected to the inside of the spray plate 210. When the water pump 160 is working, it pressurizes the water inside the water tank 130 and delivers it to the spray plate 210, so that the water is sprayed out from each set of spray nozzles 220 of the spray plate 210.

[0061] More specifically, in this embodiment, the workbench 120 is also provided with a drainage trough 150, which is used to drain the water in the T-shaped groove 200, and the debris carried in the water will be discharged into the drainage trough 150 along with the water.

[0062] It should be noted that when the two clamps 300 in this embodiment need to be replaced on the workbench 120, the operator will remove the first T-bolt 310 and the second T-bolt 320 of the two clamps 300, which will cause the first sealing plate 240 and the second sealing plate 250 to slide. Therefore, after removing the two clamps 300, it is necessary to reset the multiple first sealing plates 240 and the second sealing plates 250 on the spray plate 210 to ensure that before installing the new clamps 300, the multiple first water outlets 221 in the T-slot 200 are in the open state and the multiple second water outlets 222 are in the blocked state.

[0063] Specifically, the fixture 300 in this embodiment includes a body 301, a positioning block 302, a clamping block 303, and a locking bolt 304. The body 301 is fixed to the worktable 120 by a first T-bolt 310 and a second T-bolt 320. The positioning block 302 is fixedly disposed on the top of the body 301. A positioning groove 305 is provided on the positioning block 302. The locking bolt 304 is threaded through the side wall of the body 301 and extends into the positioning groove 305. One end of the locking bolt 304 located in the positioning groove 305 is fixedly connected to the clamping block 303. When the locking bolt 304 rotates, it can drive the clamping block 303 toward or away from the positioning block 302, thereby clamping or releasing the lens barrel workpiece.

[0064] It should also be noted that a special tool is required to reset the first sealing plate 240 and the second sealing plate 250. This tool has two parts: an upper handle, which is cylindrical, and a lower rectangular block. The short side of the rectangular block has an arc-shaped convex surface. The width of the rectangular block is the same as the width of the opening above the T-slot 200. The furthest distance between the two arc-shaped convex surfaces is the same as the width below the T-slot 200, so that the arc-shaped surfaces at both ends of the rectangular block can rub against the first friction surface 243 of the first sealing plate 240 and the second friction surface 253 of the second sealing plate 250 on the two water spray plates 210 below the T-slot 200. When using the tool, the operator passes the rectangular block of the lower part of the tool through the T-slot 200. After passing through the T-slot 200, the handle is rotated 90°, so that the lower... The convex arc surfaces at both ends of a rectangular block can rub against the first friction surface 243 or the second friction surface 253 on the two spray plates 210. Then, the tool is slid from both ends of the T-slot 200 toward the middle. The convex arc surfaces at both ends of the rectangular block can move the first sealing plate 240 and the second sealing plate 250 to reset. Specifically, the first sealing plate 240 and the second sealing plate 250 on the left side of the midpoint of the spray plate 210 are moved to the right, so that the first sealing plate 240 on the left and right sides of the midpoint of the spray plate 210 opens the first water outlet 221 and the second sealing plate 250 blocks the second water outlet 222. After the tool moves to the middle position of the T-slot 200, it is rotated 90° again and then removed, thus completing the reset of the first sealing plate 240 and the second sealing plate 250.

[0065] The specific working process of a dual-station drilling and milling platform for mirror barrel machining provided by the present invention will be described in conjunction with the above embodiments:

[0066] When installing the two clamps 300, the operator first roughly fixes the position of the left clamp 300, then passes the first T-bolt 310 of the left clamp 300 through the left side of the T-slot 200, moving it to the left side of the left clamp 300 and fixing its position. When the first T-bolt 310 passes through the left side of the T-slot 200, the T-bolt makes frictional contact with the first sealing plate 240 and the second sealing plate 250. This is because the water nozzle at the left side of the midpoint of the spray plate 210... The first sealing plate 240 and the second sealing plate 250 on 220 are already at their rightmost positions. This means the first outlet 221 is open and the second outlet 222 is blocked. The T-bolt moving from left to right within the T-slot 200 will not move the first sealing plate 240 and the second sealing plate 250 to the left of the midpoint of the spray plate 210. Meanwhile, the second T-bolt 320 moves from right to left through the T-slot 200, and before passing the midpoint of the spray plate 210, the area to the right of the midpoint of the spray plate 210... The first sealing plate 240 and the second sealing plate 250 do not move. When the second T-bolt 320 passes the midpoint of the spray plate 210, the second T-bolt 320 will drive the first sealing plate 240 and the second sealing plate 250 on the left side of the midpoint of the spray plate 210 to move synchronously from right to left, thereby blocking the first water outlet 221 on the left side of the midpoint of the spray plate 210 and opening the second water outlet 222. Similarly, the installation of the clamp 300 on the right side is the same as that on the left side, except that there are two clamps. The T-slots 200 of the clamps 300 are installed in different positions, one on the left side and the other on the right side. Furthermore, the first T-bolts 310 and the second T-bolts 320 at both ends of the two clamps 300 are not in the same T-slot 200. Therefore, the left side of the T-slot 200 of the right clamp 300 is longer, and the second water outlet 222 on the right side of the midpoint of the spray plate 210 of the T-slot 200 will supplement water to the longer left side of the T-slot 200.

[0067] Start water pump 160:

[0068] When the water pump 160 starts, it transports water from the water tank 130 to the inside of the spray plate 210 through the water pipe 140. Water is sprayed out from each set of spray nozzles 220 of the spray plate 210. When the first outlet 221 of the spray nozzle 220 is opened, water is sprayed out from the first outlet 221. When the second outlet 222 of the spray nozzle 220 is opened, water is sprayed out from the second outlet 222. This allows the debris generated by the drill and milling head 110 during operation to be discharged from the T-slot 200 into the drainage trough 150. The debris is carried away by the water, thus preventing the debris from accumulating in the T-slot 200.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
