A drilling machine with recyclable cutting fluid

Abstract

This invention relates to the field of machining technology and discloses a drilling machine with recyclable cutting fluid, comprising a main body, a precision drilling mechanism, a synchronous feeding mechanism, and a circulating oil cooling mechanism. The main body has an internal cavity, and a machining table is fixedly mounted on the top of the main body. Several fixtures are movably mounted on the surface of the machining table. In this invention, the drilling machine with recyclable cutting fluid can cause the right vertical bar at its right end to move downwards when the right horizontal bar moves downwards. This causes the positioning baffle at the bottom of the right vertical bar to move downwards accordingly. When the positioning baffle moves downwards, it first contacts the worktable. At this point, the positioning baffle stops moving, and the connecting block on its outer side slides against the slide groove, compressing the spring and generating downward pressure on the positioning baffle, thus fixing the positioning baffle. During drilling, the right side of the fixture engages with the positioning baffle, thereby enabling precise positioning of the fixture and workpiece during drilling, achieving precise drilling of the workpiece and improving machining accuracy.

Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a drilling machine with recyclable cutting fluid. Background Technology

[0002] Drilling is the process of creating a hole in a workpiece by applying pressure with a rotating drill bit, causing it to cut the workpiece material. Drill bits are typically made of cemented carbide or other wear-resistant materials to ensure efficient material cutting during the drilling process. A drilling machine is a machining tool primarily used to create holes in workpieces, such as drilling, reaming, boring, and tapping. Drill machines have a relatively simple structure but relatively low machining accuracy, and are widely used in various industries including machinery manufacturing, aerospace, automotive manufacturing, and electronics.

[0003] Existing drilling machines require a separate positioning device to position the workpiece, resulting in low machining accuracy. Furthermore, manual loading is necessary, impacting machining efficiency. Additionally, the cooling oil used during drilling cannot be recycled, leading to high costs. Therefore, a drilling machine with recyclable cutting fluid is proposed. Summary of the Invention

[0004] The present invention addresses the technical problems of existing drilling machines, which require a separate positioning device to position the workpiece, resulting in low machining accuracy and the need for manual loading, affecting machining efficiency. Furthermore, the cooling oil used during drilling cannot be recycled, leading to high costs. The present invention provides a drilling machine with recyclable cutting fluid.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A drilling machine with recyclable cutting fluid includes a main body, a precision drilling mechanism, a synchronous feeding mechanism, and a circulating oil cooling mechanism;

[0007] The main body has an internal cavity. A processing table is fixedly mounted on the top of the main body. Several clamps are movably mounted on the surface of the processing table. Each clamp has a fixing groove on its top, and a workpiece is detachably mounted inside the fixing groove. The shape and size of the fixing groove match the workpiece. A precision drilling mechanism is located on the top of the processing table. A synchronous feeding mechanism is located on the side of the precision drilling mechanism. A circulating oil cooling mechanism is located inside the internal cavity. Several supports are fixedly mounted on the bottom of the main body. In use, the workpiece is fixed by the fixing groove on the top of the clamp. Then, the clamp and workpiece are placed at the bottom of the precision drilling mechanism. The precision drilling mechanism can perform precise drilling on the workpiece. After drilling, the synchronous feeding mechanism can automatically feed the workpiece and clamp, improving processing efficiency. During drilling, the circulating oil cooling mechanism can cool and lubricate the workpiece and drill bit, and the cooling oil can be recycled to reduce waste.

[0008] Furthermore, the precision drilling mechanism includes a column fixedly mounted on the top rear side of the processing table, perpendicular to the processing table. A housing is fixedly mounted on the top of the column, and a drive motor is fixedly mounted on the bottom rear side of the housing, with the output end of the drive motor facing the top of the housing. A vertical shaft is rotatably mounted on the bottom front side of the housing, parallel to the column. The output end of the drive motor is connected to the top of the vertical shaft via a coupling. An adjusting shaft is vertically mounted on the right side wall of the housing, with a control handle fixedly mounted on its outer end. A lifting device is mounted on the upper part of the vertical shaft, and the control handle is connected to the lifting device via the adjusting shaft. When drilling, the drive motor is started, and the vertical shaft begins to rotate via the coupling between the drive motor output end and the top of the vertical shaft. At this time, rotating the control handle controls the lifting device via the adjusting shaft, causing the vertical shaft to move downwards.

[0009] Furthermore, an outer ring is fitted around the middle of the vertical shaft, and the outer ring is rotatably connected to the vertical shaft. A movable rod is connected between the outer ring and the column, and a slider is provided at the connection between the movable rod and the column. The slider is slidably connected to the column. A tool holder is fixedly provided at the bottom end of the vertical shaft, and a drill bit is detachably provided at the bottom of the tool holder. The clamp and the workpiece are located directly below the drill bit. When the vertical shaft moves downward, it drives the outer ring downward. When the outer ring moves downward, it drives the movable rod downward, causing the slider at the other end of the movable rod to slide downward along the column. When the vertical shaft moves downward and rotates, it drives the bottom tool holder downward and simultaneously begins to rotate, causing the drill bit at the bottom of the tool holder to rotate while moving downward, thus drilling a hole in the workpiece.

[0010] Furthermore, a right horizontal bar is fixedly provided on the right side of the outer sleeve ring, and the right horizontal bar is perpendicular to the vertical axis. A right vertical bar is fixedly provided at the other end of the right horizontal bar, and the right vertical bar is parallel to the vertical axis. A positioning baffle is movably provided at the bottom of the right vertical bar. A connecting block is provided at the connection between the outer wall of the positioning baffle and the right vertical bar. A sliding groove is provided at the connection between the right vertical bar and the connecting block. The connecting block is slidably connected to the sliding groove. A spring is connected between the top of the sliding groove and the top of the connecting block. The cross-sectional shape of the positioning baffle matches the shape of the right edge of the clamp. The initial position of the bottommost end of the positioning baffle is lower than the bottommost end of the drill bit. When the outer ring moves downward, it drives the right horizontal bar on the right side to move downward. When the right horizontal bar moves downward, it drives the right vertical bar at its right end to move downward, causing the positioning baffle at the bottom of the right vertical bar to move downward as well. When the positioning baffle moves downward, it first contacts the worktable. At this time, the positioning baffle stops moving, and the connecting block on its outer side slides against the slide groove, causing the spring to compress and exert downward pressure on the positioning baffle, thus fixing the positioning baffle. When drilling, the right side of the fixture is engaged with the positioning baffle, so that the fixture and the workpiece can be fully and accurately positioned during drilling, achieving precise drilling of the workpiece and improving processing accuracy.

[0011] Furthermore, the synchronous feeding mechanism includes a left-hand folding rod, with an upper collar fixedly mounted at the other end of the left-hand folding rod. A threaded rod is disposed inside the upper collar, and the threaded rod is threadedly connected to the upper collar. A left horizontal rod is fixedly mounted on the left side of the middle portion of the column, and a lower collar is fixedly mounted at the left end of the left horizontal rod. The bottom end of the threaded rod passes through the lower collar and extends to the bottom of the lower collar. The lower side of the threaded rod is rotatably connected to the lower collar. The lower collar and the upper collar are coaxially arranged, and the threaded rod is parallel to the vertical axis. When the outer collar moves downward, it drives the left-hand folding rod downward, causing the upper collar at the other end of the left-hand folding rod to move downward. When the upper collar moves downward, it drives the threaded rod threadedly connected to it to begin rotating.

[0012] Furthermore, a drive gear is fixedly mounted at the bottom end of the threaded rod, and the drive gear is coaxially arranged with the threaded rod. A movable rack is threaded through the bottom of the column, and the movable rack is slidably connected to the column. The movable rack is parallel to the left crossbar and is located in front of the drive gear, meshing with the drive gear. When the threaded rod rotates, it drives the meshing movable rack to move horizontally to the right, and vice versa.

[0013] Furthermore, the left end of the movable rack is fixedly mounted on the loading baffle, the cross-sectional shape of which matches the shape of the left side of the fixture. A lower connecting rod is fixedly mounted at the bottom of the connection between the movable rack and the loading baffle, and the bottom end of the lower connecting rod extends to the bottom of the processing table. When the movable rack moves to the right, it drives the loading baffle and the lower connecting rod at the left end to move to the left, causing the loading baffle to push the workpiece and fixture on the right side to move to the right. This achieves synchronous loading during drilling, improving processing efficiency. During the movement, the left side of the fixture engages with the loading baffle, further fixing the fixture and workpiece and significantly improving processing accuracy.

[0014] Furthermore, the circulating oil cooling mechanism includes a liquid storage tank, which is fixedly disposed in the middle of the movable rod. A cooling oil inlet pipe is connected to the top of the liquid storage tank, and a cooling oil outlet pipe is connected to the bottom of the liquid storage tank. A valve is fixedly disposed in the middle of the cooling oil outlet pipe, and a lever switch is movably disposed on the side of the valve facing the column. A stop block is fixedly disposed in the middle of the front side of the column, and the lever switch abuts against the stop block. A universal nozzle is disposed at the bottom of the cooling oil outlet pipe, and the output end of the universal nozzle faces the output end of the drill bit. When the movable lever moves downward, it drives the liquid reservoir downward. This downward movement of the liquid reservoir, in turn, drives the cooling oil output pipe and valve at the bottom downward. The downward movement of the valve, in turn, drives the lever switch downward. When the lever switch moves downward, it contacts the stop block and receives an upward thrust, causing the lever switch to move upward. This opens the valve, and cooling oil is sprayed out along the universal nozzle at the bottom, cooling and lubricating the workpiece and drill bit. After drilling is complete, the valve moves in the opposite direction, causing the lever switch to receive an upward thrust and close, automatically stopping the spraying of cooling oil. This effectively reduces the waste of cooling oil.

[0015] Furthermore, the processing table has several overflow holes on its central surface, a filter chamber is fixedly installed at the bottom center of the processing table, the top of the filter chamber is connected to the overflow holes, a filter plate is fixedly installed at the center of the filter chamber, a cleaning rod is movably installed on the top of the filter plate, the top of the cleaning rod is fixedly connected to the bottom end of the lower connecting rod, a slot is opened on the upper left side of the filter plate, the bottom end of the slot is flush with the surface of the filter plate, a collection groove is fixedly installed on the outer side of the slot, an oblique hole is opened at the bottom of the collection groove and the side wall of the filter chamber, the oblique hole is located at the bottom of the filter plate, and a filter screen is installed inside the oblique hole. During drilling, the feed baffle is located at the far right end, and the lower connecting rod is also located at the far right end. The cleaning rod is located at the far right of the filter plate surface. Cooling oil and waste materials during processing flow into the filter chamber through the overflow hole. After being filtered by the filter plate, the waste materials in the cooling oil are filtered onto the filter plate surface. When processing is completed, the movable rack moves to the left, driving the lower connecting rod to move to the left, causing the cleaning rod to move to the left as well. During the movement, the cleaning rod sweeps the waste materials on the filter plate surface into the slot on the left side of the filter plate, so that the waste materials are collected into the collection tank. The residual coolant in the collection tank is filtered through the filter screen and flows back into the filter chamber through the inclined hole at the bottom, thereby realizing the synchronous and automatic collection of waste materials on the filter plate surface and avoiding the filter plate from being blocked.

[0016] Furthermore, a liquid outlet is provided at the center of the bottom of the filter chamber. The bottom end of the liquid outlet is connected to a liquid pump via a liquid pump inlet pipe, and the output end of the liquid pump is connected to a liquid pump outlet pipe, which is connected to the cooling oil inlet pipe. The filtered cooling oil flows into the liquid pump along the liquid pump inlet pipe and is then pumped out again along the liquid pump outlet pipe, thereby realizing the recycling of cooling oil and reducing processing costs.

[0017] The beneficial effects of this invention are:

[0018] 1. The drilling machine with recyclable cutting fluid of the present invention, by setting a precision drilling mechanism, can drive the right crossbar on the right side to move downward when the outer ring moves downward. When the right crossbar moves downward, it drives the right vertical bar at the bottom right end to move downward, so that the positioning baffle at the bottom of the right vertical bar moves downward accordingly. When the positioning baffle moves downward, it first contacts the worktable. At this time, the positioning baffle stops moving, and the connecting block on its outer side slides against the slide groove, so that the spring is compressed and exerts downward pressure on the positioning baffle, fixing the positioning baffle. When drilling, the right side of the fixture is engaged with the positioning baffle, so that the fixture and the workpiece can be fully and accurately positioned during drilling, thereby achieving precise drilling of the workpiece and improving the machining accuracy.

[0019] 2. The drilling machine with recyclable cutting fluid of the present invention, by being equipped with a synchronous feeding mechanism, can drive the feeding baffle at the left end to move to the left when the movable rack moves to the right, so that the feeding baffle pushes the workpiece and fixture on the right side to move to the right, thereby realizing synchronous feeding during drilling, improving processing efficiency. During the movement, the left side of the fixture engages with the feeding baffle, thereby further fixing the fixture and workpiece, and significantly improving processing accuracy.

[0020] 3. The drilling machine with recyclable cutting fluid of the present invention, by being equipped with a circulating oil cooling mechanism, can drive the reservoir downward when the movable rod moves downward. The downward movement of the reservoir drives the cooling oil output pipe and valve at the bottom downward. The downward movement of the valve drives the lever switch downward. When the lever switch moves downward, it contacts the stop block and receives an upward thrust, causing the lever switch to move upward, opening the valve. Cooling oil is sprayed out along the universal nozzle at the bottom to cool and lubricate the workpiece and drill bit. When drilling is completed, the valve moves in the reverse direction, causing the lever switch to receive an upward thrust and close, automatically stopping the spraying of cooling oil. This effectively reduces the cooling... Oil waste is eliminated. After processing, the movable rack moves to the left, driving the lower connecting rod to move to the left, causing the cleaning rod to move to the left as well. During the movement, the cleaning rod sweeps the waste material on the surface of the filter plate into the slot on the left side of the filter plate, so that the waste material is collected into the collection tank. The residual coolant in the collection tank is filtered through the filter screen and then flows back into the filter chamber through the inclined holes at the bottom, thus realizing the synchronous and automatic collection of waste material on the surface of the filter plate and avoiding the filter plate from being blocked. As a result, the filtered coolant flows into the liquid pump through the liquid pump inlet pipe and then is pumped out again through the liquid pump outlet pipe, thus realizing the recycling of coolant and reducing processing costs.

[0026] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0027] like Figure 1-4 As shown, a drilling machine with recyclable cutting fluid includes a main body 1, a precision drilling mechanism, a synchronous feeding mechanism, and a circulating oil cooling mechanism.

[0028] The main body 1 has an internal cavity 23. A processing table 2 is fixedly mounted on the top of the main body 1. Several clamps 3 are movably mounted on the surface of the processing table 2. A fixing groove is formed on the top of each clamp 3. A workpiece 4 is detachably mounted inside the fixing groove. The shape and size of the fixing groove match the workpiece 4. A precision drilling mechanism is located on the top of the processing table 2. A synchronous feeding mechanism is located on the side of the precision drilling mechanism. A circulating oil cooling mechanism is located inside the internal cavity 23. Several supports are fixedly mounted on the bottom of the main body 1. In use, the workpiece 4 is fixed by the fixing groove on the top of the clamp 3. Then, the clamp 3 and the workpiece 4 are placed at the bottom of the precision drilling mechanism. The precision drilling mechanism can perform precision drilling on the workpiece 4. After drilling is completed, the synchronous feeding mechanism can automatically feed the workpiece 4 and the clamp 3, improving processing efficiency. During the drilling process, the circulating oil cooling mechanism can cool and lubricate the workpiece 4 and the drill bit 12, and the cooling oil can be recycled to reduce waste.

[0029] The precision drilling mechanism includes a column 5, which is fixedly mounted on the top rear side of the processing table 2. The column 5 is perpendicular to the processing table 2. A housing 6 is fixedly mounted on the top of the column 5. A drive motor 36 is fixedly mounted on the bottom rear side of the housing 6, with the output end of the drive motor 36 facing the top of the housing 6. A vertical shaft 9 is rotatably mounted on the bottom front side of the housing 6, parallel to the column 5. The output end of the drive motor 36 is connected to the top of the vertical shaft 9 via a coupling. An adjusting shaft 8 is vertically mounted on the right side wall of the housing 6, with a control handle 7 fixedly mounted on the outer end of the adjusting shaft 8. A lifting device is mounted on the upper part of the vertical shaft 9, and the control handle 7 is connected to the lifting device via the adjusting shaft 8. When drilling, the drive motor 36 is started, and the vertical shaft 9 begins to rotate through the coupling between the output end of the drive motor 36 and the top of the vertical shaft 9. At this time, rotating the control handle 7 controls the lifting device via the adjusting shaft 8 to move the vertical shaft 9 downward.

[0030] An outer ring 10 is fitted around the middle of the vertical shaft 9, and the outer ring 10 is rotatably connected to the vertical shaft 9. A movable rod 38 connects the outer ring 10 to the column 5. A slider 45 is provided at the connection between the movable rod 38 and the column 5, and the slider 45 is slidably connected to the column 5. A tool holder 11 is fixedly provided at the bottom of the vertical shaft 9, and a drill bit 12 is detachably provided at the bottom of the tool holder 11. The clamp 3 and the workpiece 4 are located directly below the drill bit 12. When the vertical shaft 9 moves downward, it drives the outer ring 10 downward. When the outer ring 10 moves downward, it drives the movable rod 38 downward, causing the slider 45 at the other end of the movable rod 38 to slide downward along the column 5. When the vertical shaft 9 moves downward and rotates, it drives the bottom tool holder downward and starts to rotate at the same time, causing the drill bit 12 at the bottom of the tool holder to rotate while moving downward, thus drilling a hole in the workpiece 4.

[0031] A right horizontal bar 21 is fixedly provided on the right side of the outer sleeve ring 10. The right horizontal bar 21 is perpendicular to the vertical axis 9. A right vertical bar 22 is fixedly provided at the other end of the right horizontal bar 21. The right vertical bar 22 is parallel to the vertical axis 9. A positioning baffle 47 is movably provided at the bottom of the right vertical bar 22. A connecting block 48 is provided at the connection between the outer wall of the positioning baffle 47 and the right vertical bar 22. A sliding groove 49 is provided at the connection between the right vertical bar 22 and the connecting block 48. The connecting block 48 is slidably connected to the sliding groove 49. A spring 50 is connected between the top of the sliding groove 49 and the top of the connecting block 48. The cross-sectional shape of the positioning baffle 47 matches the shape of the right edge of the clamp 3. The initial position of the bottommost end of the positioning baffle 47 is lower than the bottommost end of the drill bit 12. When the outer ring 10 moves downward, it drives the right horizontal bar 21 on the right side to move downward. When the right horizontal bar 21 moves downward, it drives the right vertical bar 22 at its right end to move downward, causing the positioning baffle 47 at the bottom of the right vertical bar 22 to move downward as well. When the positioning baffle 47 moves downward, it first contacts the worktable. At this time, the positioning baffle 47 stops moving, and the connecting block 48 on its outer side slides against the slide groove 49, causing the spring 50 to compress and exert downward pressure on the positioning baffle 47, thus fixing the positioning baffle 47. When drilling, the right side of the fixture 3 is engaged with the positioning baffle 47, so that the fixture 3 and the workpiece 4 can be accurately positioned during drilling, achieving accurate drilling of the workpiece 4 and improving processing accuracy.

[0032] The synchronous feeding mechanism includes a left folding rod 13, with an upper collar 14 fixedly mounted at the other end of the left folding rod 13. A threaded rod 15 is disposed inside the upper collar 14, and the threaded rod 15 is threadedly connected to the upper collar 14. A left horizontal rod 16 is fixedly mounted on the left side of the middle portion of the column 5, and a lower collar 17 is fixedly mounted at the left end of the left horizontal rod 16. The bottom end of the threaded rod 15 passes through the lower collar 17 and extends to the bottom of the lower collar 17. The lower side of the threaded rod 15 is rotatably connected to the lower collar 17. The lower collar 17 and the upper collar 14 are coaxially arranged, and the threaded rod 15 is parallel to the vertical axis 9. When the outer collar 10 moves downward, it drives the left folding rod 13 downward, causing the upper collar 14 at the other end of the left folding rod 13 to move downward. When the upper collar 14 moves downward, it drives the threaded rod 15, which is threadedly connected to it, to begin rotating.

[0033] A drive gear 18 is fixedly mounted at the bottom end of the threaded rod 15. The drive gear 18 is coaxially mounted with the threaded rod 15. A movable rack 19 is threaded through the bottom of the column 5. The movable rack 19 is slidably connected to the column 5 and is parallel to the left crossbar 16. The movable rack 19 is located in front of the drive gear 18 and meshes with it. When the threaded rod 15 rotates, it drives the meshing movable rack 19 to move to the right in the horizontal direction; conversely, the movable rack 19 moves to the left.

[0034] The left end of the movable rack 19 is fixedly mounted on the loading baffle 20. The cross-sectional shape of the loading baffle 20 matches the shape of the left side of the fixture 3. A lower connecting rod 28 is fixedly mounted at the bottom of the connection between the movable rack 19 and the loading baffle 20, and the bottom end of the lower connecting rod 28 extends to the bottom of the processing table 2. When the movable rack 19 moves to the right, it drives the loading baffle 20 and the lower connecting rod 28 to move to the left, causing the loading baffle 20 to push the workpiece 4 and the fixture 3 on the right side to move to the right. This achieves synchronous loading during drilling, improving processing efficiency. During the movement, the left side of the fixture 3 engages with the loading baffle 20, further fixing the fixture 3 and the workpiece 4 and significantly improving processing accuracy.

[0035] The circulating oil cooling mechanism includes a liquid storage tank 39, which is fixedly disposed in the middle of the movable rod 38. A cooling oil inlet pipe 37 is connected to the top of the liquid storage tank 39, and a cooling oil outlet pipe 40 is connected to the bottom of the liquid storage tank 39. A valve 41 is fixedly disposed in the middle of the cooling oil outlet pipe 40. A lever switch 43 is movably disposed on the side of the valve 41 facing the column 5. A stop block 44 is fixedly disposed in the middle of the front side of the column 5. The lever switch 43 abuts against the stop block 44. A universal nozzle 42 is disposed at the bottom of the cooling oil outlet pipe 40, and the output end of the universal nozzle 42 faces the output end of the drill bit 12. When the movable lever 38 moves downward, it drives the liquid storage cylinder 39 downward. When the liquid storage cylinder 39 moves downward, it drives the cooling oil output pipe 40 and valve 41 at the bottom downward. When the valve 41 moves downward, it drives the lever switch 43 downward. When the lever switch 43 moves downward, it contacts the stop block 44 and receives an upward thrust, causing the lever switch 43 to move upward. The valve 41 opens, and the cooling oil is sprayed out along the universal nozzle 42 at the bottom to cool and lubricate the workpiece 4 and the drill bit 12. When drilling is completed, the valve 41 moves in the opposite direction, causing the lever switch 43 to receive an upward thrust and close. The cooling oil automatically stops spraying out, which can effectively reduce the waste of cooling oil.

[0036] The processing table 2 has several overflow holes 24 on its central surface. A filter chamber 25 is fixedly installed at the bottom center of the processing table 2. The top of the filter chamber 25 is connected to the overflow holes 24. A filter plate 26 is fixedly installed at the center of the filter chamber 25. A cleaning rod 27 is movably installed on the top of the filter plate 26. The top of the cleaning rod 27 is fixedly connected to the bottom end of the lower connecting rod 28. A slot 29 is opened on the upper left side of the filter plate 26. The bottom end of the slot 29 is flush with the surface of the filter plate 26. A collection groove 30 is fixedly installed on the outer side of the slot 29. An inclined hole 31 is opened at the bottom of the collection groove 30 and the side wall of the filter chamber 25. The inclined hole 31 is located at the bottom of the filter plate 26. A filter screen is installed inside the inclined hole 31. During drilling, the feed baffle 20 is located at the rightmost end, and the lower connecting rod 28 is also located at the rightmost end. The cleaning rod 27 is located at the rightmost side of the filter plate 26 surface. The cooling oil and waste material during processing flow into the filter chamber 25 through the overflow hole 24. After being filtered by the filter plate 26, the waste material in the cooling oil is filtered onto the surface of the filter plate 26. When processing is completed, the movable rack 19 moves to the left, driving the lower connecting rod 28 to move to the left, causing the cleaning rod 27 to move to the left as well. During the movement, the cleaning rod 27 sweeps the waste material on the surface of the filter plate 26 into the slot 29 on the left side of the filter plate 26, so that the waste material is collected into the collection tank 30. The residual coolant in the collection tank 30 is filtered by the filter screen and then flows back into the filter chamber 25 through the inclined hole 31 at the bottom, thereby realizing the synchronous automatic collection of waste material on the surface of the filter plate 26 and preventing the filter plate 26 from being blocked.

[0037] The filter chamber 25 has a liquid outlet 32 ​​at its bottom center. The bottom end of the liquid outlet 32 ​​is connected to a liquid pump 34 via a liquid pump 34 input pipe 33. The output end of the liquid pump 34 is connected to a liquid pump 34 output pipe, and the liquid pump 34 output pipe is connected to the cooling oil input pipe 37. The filtered cooling oil flows into the liquid pump 34 along the liquid pump 34 input pipe 33, and then is pumped out again along the liquid pump 34 output pipe, thereby realizing the recycling of cooling oil and reducing processing costs.

[0038] Working principle: When drilling, the drive motor 36 is started. The vertical shaft 9 is driven to rotate via the coupling between the output end of the drive motor 36 and the top of the vertical shaft 9. At this time, rotating the control handle 7 controls the lifting device via the adjusting shaft 8, causing the vertical shaft 9 to move downwards. As the vertical shaft 9 moves downwards, it drives the outer ring 10 downwards. The outer ring 10 then drives the movable rod 38 downwards, causing the slider 45 at the other end of the movable rod 38 to slide downwards along the column 5. As the vertical shaft 9 moves downwards and rotates, it drives the bottom tool holder downwards and simultaneously rotates, causing the drill bit 12 at the bottom of the tool holder to rotate while moving downwards, thus drilling the workpiece 4. The outer ring 10 moves downwards... During movement, the right horizontal bar 21 on the right side moves downward. When the right horizontal bar 21 moves downward, it drives the right vertical bar 22 at its bottom right end to move downward, causing the positioning baffle 47 at the bottom of the right vertical bar 22 to move downward as well. When the positioning baffle 47 moves downward, it first contacts the worktable. At this time, the positioning baffle 47 stops moving, and the connecting block 48 on its outer side slides against the slide groove 49, causing the spring 50 to compress and exert downward pressure on the positioning baffle 47, thus fixing the positioning baffle 47. When drilling, the right side of the fixture 3 is engaged with the positioning baffle 47, so that the fixture 3 and the workpiece 4 can be accurately positioned during drilling, achieving accurate drilling of the workpiece 4 and improving processing accuracy.

[0039] When the outer ring 10 moves downward, it drives the left folding rod 13 to move downward, causing the upper ring 14 at the other end of the left folding rod 13 to move downward. When the upper ring 14 moves downward, it drives the threaded rod 15 connected to it to start rotating. When the threaded rod 15 rotates, it drives the movable rack 19 that meshes with it to move to the right in the horizontal direction. Conversely, the movable rack 19 moves to the left. When the movable rack 19 moves to the right, it drives the left end of the loading baffle 20 and the lower connecting rod 28 to move to the left, so that the loading baffle 20 pushes the workpiece 4 and the fixture 3 on the right side to move to the right. This achieves synchronous loading during drilling, improving processing efficiency. During the movement, the left side of the fixture 3 engages with the loading baffle 20, which can further fix the fixture 3 and the workpiece 4, thus fully improving the processing accuracy.

[0040] When the movable rod 38 moves downward, it drives the liquid storage cylinder 39 downward. The downward movement of the liquid storage cylinder 39 drives the cooling oil output pipe 40 and valve 41 at the bottom downward. The downward movement of valve 41 drives the lever switch 43 downward. When the lever switch 43 moves downward, it contacts the stop block 44 and receives an upward thrust, causing the lever switch 43 to move upward. This opens valve 41, and cooling oil is sprayed out along the universal nozzle 42 at the bottom, cooling and lubricating the workpiece 4 and drill bit 12. After drilling is completed, valve 41 moves in the reverse direction, causing the lever switch 43 to receive an upward thrust and close, automatically stopping the spraying of cooling oil, thus effectively reducing cooling oil waste. During drilling, the loading baffle 20 is located at the rightmost end, and the lower connecting rod 28 is also located at the rightmost end. The cleaning rod 27 is located at the rightmost side of the filter plate 26 surface. The cooling oil and waste materials generated during processing flow along... Overflow hole 24 flows into the interior of filter chamber 25. After being filtered by filter plate 26, waste in the cooling oil is filtered onto the surface of filter plate 26. After processing is completed, movable rack 19 moves to the left, driving lower connecting rod 28 to move to the left, causing cleaning rod 27 to move to the left as well. During the movement, cleaning rod 27 sweeps the waste on the surface of filter plate 26 into the slot 29 on the left side of filter plate 26, so that the waste is collected into collection tank 30. The residual coolant in collection tank 30 is filtered by filter screen and flows back into filter chamber 25 through inclined hole 31 at the bottom, thus realizing synchronous automatic collection of waste on the surface of filter plate 26 and avoiding filter plate 26 from being blocked. The filtered cooling oil flows into liquid pump 34 through liquid pump 34 input pipe 33, and then is pumped out again through liquid pump 34 output pipe, thus realizing the recycling of cooling oil and reducing processing costs.
