[0004] The aforementioned patent avoids the problem of large clamping errors caused by frequent machine tool changes due to single function. At the same time, it is used in conjunction with a cam to shorten the cutting stroke and greatly improve the cutting speed. It completely solves the problem of short machine tool life caused by ball screw wear. However, the drill temperature may be too high during milling, which may reduce the life of the drill. Also, the material may shake up and down during milling, affecting the milling effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a vertical CNC drilling and milling machine tool, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vertical CNC drilling and milling machine tool, comprising: a machine housing; a rotary door rotatably mounted on the inner wall of the machine housing; a water tank disposed on the inner wall of the machine housing; an automated drilling and milling device disposed on the top of the inner wall of the machine housing; a water spray pipe fixedly mounted on the output end of the automated drilling and milling device, the water tank and the water spray pipe being connected by a water pipe; a worktable fixedly mounted on the bottom of the inner wall of the machine housing, a fixed platform fixedly mounted on the top of the worktable, and a screw motor fixedly mounted on the inner wall of the machine housing, the screw motor having helical grooves on its surface, the two helical grooves rotating in opposite directions, the screw motor outputting... A movable frame is threadedly mounted at the output end. The movable frame is slidably mounted on the inner wall of the worktable. A connecting block is fixedly mounted on the top of the movable frame. A sealing plate is fixedly mounted on the top of the connecting block. A clamping plate is fixedly mounted on the top of the sealing plate. A sliding plate is slidably mounted on the inner wall of the fixed table. A screw rod is fixedly mounted on the side of the sliding plate away from the clamping plate. A rotating plate is rotatably mounted on the inner wall of the fixed table. The screw rod is threadedly connected to the rotating plate. The machine housing is equipped with a filter device for filtering iron filings and a drainage device. By placing the workpiece on the fixed table and then starting the screw motor, the rotation of the output end of the screw motor will drive the movable frame to move in the opposite direction. The movement of the movable frame in the opposite direction will drive the connecting block to move in the opposite direction.

[0007] According to the above technical solution, a first spring is provided between the fixed platform and the sliding plate. When the sliding plate is separated from the clamp, the elastic force of the first spring will drive the sliding plate to return to its original position. A first torsion spring is provided between the fixed platform and the rotating plate. The first torsion spring will drive the rotating plate to return to its original position through its own elastic force.

[0008] According to the above technical solution, the filtration device includes a trapezoidal plate, a rotating shaft, a short plate, a filter frame, a filter plate, and a collection frame. The trapezoidal plate moves away from the moving frame as the moving frame moves closer to the fixed platform. This movement of the trapezoidal plate away from the moving frame causes the short plate to rotate upwards. The trapezoidal plate is slidably mounted on the inner wall of the workbench. The rotating shaft is rotatably mounted on the inner wall of the machine housing. The short plate is fixedly mounted on the circumferential surface of the rotating shaft. The filter frame is fixedly mounted on the circumferential surface of the rotating shaft. The filter plate is slidably mounted on the inner wall of the filter frame. A collection groove is provided on the inner wall of the machine housing, and a collection frame is slidably mounted on the inner wall of the collection groove.

[0009] According to the above technical solution, a rotating rod is rotatably installed on the inner wall of the chassis, and a roller is rotatably installed on the surface of the rotating rod. A semicircular block is fixedly installed on the top of the filter plate. The roller will contact the semicircular block and push the semicircular block downwards. The downward movement of the semicircular block will drive the filter plate downwards.

[0010] According to the above technical solution, a second spring is provided between the trapezoidal plate and the worktable. When the moving frame is reset, the elastic force of the second spring will drive the trapezoidal plate to reset. A second torsion spring is provided between the rotating shaft and the machine box. The elastic force of the second torsion spring will drive the rotating shaft to reset. A reset spring is provided between the filter plate and the filter frame. The elastic force of the reset spring will drive the filter plate to reset. A third torsion spring is provided between the machine box and the rotating rod. The elastic force of the third torsion spring will drive the rotating rod to reset.

[0011] According to the above technical solution, the drainage device includes a sliding plate, a pulley, an L-shaped plate, and a fixed plate. When the filter frame rotates upward, it will disengage from the pulley and the sliding plate will move upward by the elastic force of the No. 3 spring. The upward movement of the sliding plate will seal the inlet of the collection frame. The sliding plate is slidably installed on the inner wall of the casing, the pulley is rotatably installed on the inner wall of the sliding plate, the L-shaped plate is fixedly installed on the surface of the sliding plate, and the fixed plate is fixedly installed on the surface of the collection frame.

[0012] According to the above technical solution, an L-shaped rod is fixedly installed on the surface of the sliding plate, a pulley frame is fixedly installed on the surface of the L-shaped rod, a sealing slide plate is slidably installed at the bottom of the collection tank, and a trapezoidal block is fixedly installed on the surface of the sealing slide plate. When the sliding plate moves upward, it will drive the L-shaped rod to move upward, and the L-shaped rod will drive the pulley frame to move upward. When the pulley frame moves upward, it will release the pressure on the trapezoidal block.

[0013] According to the above technical solution, a No. 3 spring is provided between the sliding plate and the chassis. When the filter frame is reset, the spring force of the No. 3 spring, which loses the pressure of the filter frame, will drive the sliding plate to reset. A No. 4 spring is provided between the collection groove and the sealing slide plate. When the sliding plate is reset, it will drive the L-shaped rod and the pulley frame to reset. When the pulley frame is reset, it will lose the pressure on the trapezoidal block, and the spring force of the No. 4 spring will drive the sealing slide plate to reset.

[0014] This invention provides a vertical CNC drilling and milling machine tool. It has the following beneficial effects:

[0015] (1) In this invention, the opposing movement of the sealing plates will drive the opposing movement of the clamping plates, which will clamp the parts to prevent them from shifting during processing and affecting the processing effect. At the same time, the water spray pipe will work with the automated drilling and milling equipment to spray water to cool down the parts and prevent the drill bit temperature from being too high during processing. This will cause the hardness and cutting performance of the tool to decrease significantly, resulting in increased cutting force, increased surface roughness, and even tool breakage. At the same time, the sealing plate will seal the top of the worktable to prevent water from entering the worktable during the water spraying process, which could cause the screw motor to rust and affect the normal operation of the equipment.

[0016] (2) In this invention, when the clamping plates move towards each other, they will push the slide plate to move closer to the rotating plate. The slide plate moving closer to the rotating plate will drive the screw rod to move closer to the rotating plate. The screw rod will push the rotating plate to rotate. The rotating plate will clamp the two sides of the part. At the same time, the rotating plate will limit the part to prevent the part from shaking up and down during the processing, which will cause the automated drilling and milling equipment to deviate during processing and affect normal use.

[0017] (3) In this invention, the filter plate rotates upward to block the collection tank, so that the water sprayed from the water pipe flows out through the drain at the bottom of the collection tank. At the same time, the iron filings generated during processing will remain on the top of the filter plate. By tilting the filter plate, the iron filings fall into the collection frame to collect them and prevent them from being discharged with water. This would cause the iron filings to undergo an oxidation reaction in the water and form rust, which would aggravate water quality deterioration, produce sediment, and increase the turbidity of the water. Meanwhile, the downward movement of the semi-circular block will drive the filter plate downward. By moving the filter plate up and down, the iron filings remaining on the filter plate will be shaken into the collection frame, improving the collection effect of iron filings. The discharged water can be recycled and reused to form a water cycle.

[0018] (4) In this invention, when the filter frame rotates upward, it will disengage from the pulley and move the sliding plate upward through the elastic force of the No. 3 spring. The upward movement of the sliding plate will seal the inlet of the collection frame to prevent water from splashing into the collection frame during water spraying, which would affect the collection effect of iron filings. At the same time, the upward movement of the sliding plate will drive the L-shaped plate to move upward. The upward movement of the L-shaped plate will limit the fixed plate to prevent the collection frame from being pulled out during processing, which would affect the collection of iron filings. The reset of the sealing slide will open the drain outlet to prevent the drain outlet from being in the open state for a long time, which would cause bacteria to grow in the water inside the drain outlet and produce an odor. The odor will enter the equipment through the drain outlet and affect the normal use of the user. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 8One embodiment of the present invention is as follows: a vertical CNC drilling and milling machine tool, comprising: a machine housing 1, a rotary door 2, the rotary door 2 being rotatably mounted on the inner wall of the machine housing 1; a water tank 3, the water tank 3 being disposed on the inner wall of the machine housing 1; an automated drilling and milling device 4, the automated drilling and milling device 4 being disposed on the top of the inner wall of the machine housing 1; a water spray pipe 5, the water spray pipe 5 being fixedly mounted on the output end of the automated drilling and milling device 4, and the water tank 3 and the water spray pipe 5 being connected by a water pipe; a worktable 6 being fixedly mounted on the bottom of the inner wall of the machine housing 1, a fixed platform 7 being fixedly mounted on the top of the worktable 6, a screw motor 8 being fixedly mounted on the inner wall of the machine housing 1, the surface of the screw motor 8 having helical grooves, the two ends of the helical grooves rotating in opposite directions, and a movable [device] being threadedly mounted on the output end of the screw motor 8. The frame 9 is slidably installed on the inner wall of the workbench 6. A connecting block 10 is fixedly installed on the top of the moving frame 9. A sealing plate 11 is fixedly installed on the top of the connecting block 10. A clamping plate 12 is fixedly installed on the top of the sealing plate 11. A sliding plate 13 is slidably installed on the inner wall of the fixed platform 7. A screw rod 14 is fixedly installed on the side of the sliding plate 13 away from the clamping plate 12. A rotating plate 15 is rotatably installed on the inner wall of the fixed platform 7. The screw rod 14 is threadedly connected to the rotating plate 15. The machine box 1 is equipped with a filter device and a drainage device for filtering iron filings. The top of the workbench 6 is sealed by the sealing plate 11 to prevent water from entering the interior of the workbench 6 during water spraying, which could cause the screw motor 8 to rust and affect the normal operation of the equipment.

[0030] A first spring is installed between the fixed platform 7 and the slide plate 13. When the slide plate 13 is separated from the clamp 12, the elastic force of the first spring will drive the slide plate 13 to return to its original position. A first torsion spring is installed between the fixed platform 7 and the rotating plate 15. The first torsion spring will drive the rotating plate 15 to return to its original position through its own elastic force.

[0031] In this embodiment, the workpiece is placed on the fixed table 7, and then the screw motor 8 is started. The rotation of the output end of the screw motor 8 will drive the moving frame 9 to move in opposite directions. The moving frame 9 will drive the connecting block 10 to move in opposite directions. The moving block 10 will drive the sealing plate 11 to move in opposite directions. The moving plate 11 will drive the clamping plate 12 to move in opposite directions. The clamping plate 12 will clamp the workpiece to prevent it from shifting during processing and affecting the processing effect.

[0032] During processing, the water spray pipe 5 will work with the automated drilling and milling equipment 4 to spray water to cool down the machine. This will prevent the drill bit temperature from getting too high during processing, which would significantly reduce the hardness and cutting performance of the tool, leading to increased cutting force, increased surface roughness, and even tool breakage. The top of the worktable 6 is sealed by the sealing plate 11 to prevent water from entering the worktable 6 during the water spraying process, which could cause the screw motor 8 to rust and affect the normal operation of the equipment.

[0033] At the same time, when the clamping plates 12 move towards each other, they will push the slide plate 13 to move closer to the rotating plate 15. The movement of the slide plate 13 towards the rotating plate 15 will drive the screw rod 14 to move closer to the rotating plate 15. The screw rod 14 will push the rotating plate 15 to rotate. The rotation of the rotating plate 15 will clamp the two sides of the part. At the same time, the rotating plate 15 will limit the part to prevent the part from shaking up and down during the processing, which would cause the automated drilling and milling equipment 4 to deviate during processing and affect normal use.

[0034] Please see Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, the filtration device includes a trapezoidal plate 161, a rotating shaft 162, a short plate 163, a filter frame 164, a filter plate 165, and a collection frame 166. The trapezoidal plate 161 is slidably installed on the inner wall of the workbench 6, the rotating shaft 162 is rotatably installed on the inner wall of the housing 1, the short plate 163 is fixedly installed on the circumferential surface of the rotating shaft 162, the filter frame 164 is fixedly installed on the circumferential surface of the rotating shaft 162, the filter plate 165 is slidably installed on the inner wall of the filter frame 164, and a collection groove is provided on the inner wall of the housing 1. The collection frame 166 is slidably installed on the inner wall of the collection groove. By rotating the filter plate 165 upwards to block the collection groove, the water sprayed from the water spray pipe 5 flows out through the drain outlet at the bottom of the collection groove. At the same time, the iron filings generated during processing will remain on the top of the filter plate 165.

[0035] A rotating rod 167 is rotatably installed on the inner wall of the casing 1, and a roller 168 is rotatably installed on the surface of the rotating rod 167. A semi-circular block 169 is fixedly installed on the top of the filter plate 165. By moving the filter plate 165 up and down, the iron filings remaining on the filter plate 165 are shaken into the collection frame 166, which improves the collection effect of iron filings. The discharged water can be recycled and reused to form a water cycle.

[0036] A second spring is installed between the trapezoidal plate 161 and the worktable 6. When the moving frame 9 is reset, the elastic force of the second spring will drive the trapezoidal plate 161 to reset. A second torsion spring is installed between the rotating shaft 162 and the housing 1. The elastic force of the second torsion spring will drive the rotating shaft 162 to reset. A reset spring is installed between the filter plate 165 and the filter frame 164. The elastic force of the reset spring will drive the filter plate 165 to reset. A third torsion spring is installed between the housing 1 and the rotating rod 167. The elastic force of the third torsion spring will drive the rotating rod 167 to reset.

[0037] In this embodiment, when the movable frame 9 moves towards the fixed platform 7, it drives the trapezoidal plate 161 to move away from the movable frame 9. The movement of the trapezoidal plate 161 away from the movable frame 9 will push the short plate 163 to rotate upward. The rotation of the short plate 163 will drive the rotating shaft 162 to rotate upward. The upward rotation of the rotating shaft 162 will drive the filter frame 164 and the filter plate 165 to rotate. The upward rotation of the filter plate 165 will block the collection tank, so that the water sprayed from the water spray pipe 5 will flow out through the drain at the bottom of the collection tank. At the same time, the iron filings generated during processing will remain on the top of the filter plate 165.

[0038] After processing, the screw motor 8 flips, which drives the moving frame 9 to move in opposite directions. The moving frame 9 moves in opposite directions and disengages from the trapezoidal plate 161. The elastic force of the second spring itself will drive the trapezoidal plate 161 to reset. The reset of the trapezoidal plate 161 will disengage from the compression of the short plate 163. The second torsion spring will drive the rotating shaft 162, filter frame 164 and filter plate 165 to reset. The tilting of the filter plate 165 will cause the iron filings to fall into the collection frame 166, collect the iron filings, and prevent the iron filings from mixing with the water and being discharged. This would cause the iron filings to undergo an oxidation reaction in the water, forming rust, which would aggravate the deterioration of water quality, produce sediment, and increase the turbidity of the water.

[0039] Simultaneously, as the filter plate 165 rotates up and down, it comes into contact with the roller 168, which in turn contacts the semicircular block 169. The roller 168 pushes the semicircular block 169 downward, which in turn moves the filter plate 165 downward. The up-and-down movement of the filter plate 165 shakes the iron filings remaining on it into the collection frame 166, improving the collection effect of iron filings. The drained water can be recycled, forming a water cycle.

[0040] The drainage device includes a sliding plate 171, a pulley 172, an L-shaped plate 173, and a fixed plate 174. The sliding plate 171 is slidably installed on the inner wall of the housing 1, the pulley 172 is rotatably installed on the inner wall of the sliding plate 171, the L-shaped plate 173 is fixedly installed on the surface of the sliding plate 171, and the fixed plate 174 is fixedly installed on the surface of the collection frame 166 to prevent water from splashing into the inside of the collection frame 166 when water is sprayed, thus affecting the collection effect of iron filings.

[0041] An L-shaped rod 175 is fixedly installed on the surface of the sliding plate 171, and a pulley frame 176 is fixedly installed on the surface of the L-shaped rod 175. A sealing plate 178 is slidably installed at the bottom of the collection tank, and a trapezoidal block 177 is fixedly installed on the surface of the sealing plate 178 to prevent the drain outlet from being in the open state for a long time, which would cause bacteria to grow in the water inside the drain outlet and produce an odor. The odor would enter the equipment through the drain outlet and affect the normal use of the equipment.

[0042] A third spring is installed between the sliding plate 171 and the housing 1. When the filter frame 164 is reset, the spring force of the third spring, which loses the pressure of the filter frame 164, will drive the sliding plate 171 to reset. A fourth spring is installed between the collection groove and the sealing slide plate 178. When the sliding plate 171 is reset, it will drive the L-shaped rod 175 and the pulley frame 176 to reset. When the pulley frame 176 is reset, it will lose the pressure on the trapezoidal block 177, and the spring force of the fourth spring will drive the sealing slide plate 178 to reset.

[0043] When the filter frame 164 rotates upward, it will release the pressure on the pulley 172. The spring force of the third spring will drive the sliding plate 171 to move upward. The upward movement of the sliding plate 171 will seal the inlet of the collection frame 166, preventing water from splashing into the collection frame 166 when water is sprayed, thus affecting the collection effect of iron filings.

[0044] At the same time, the upward movement of the sliding plate 171 will drive the L-shaped plate 173 to move upward. The upward movement of the L-shaped plate 173 will limit the fixed plate 174 to prevent the collection frame 166 from being pulled out during processing, which would affect the collection of iron filings. At the same time, the upward movement of the sliding plate 171 will drive the L-shaped rod 175 to move upward. The upward movement of the L-shaped rod 175 will drive the pulley frame 176 to move upward. The upward movement of the pulley frame 176 will release the pressure on the trapezoidal block 177.

[0045] The elastic force of the No. 4 spring causes the sealing slide plate 178 to reset. The reset of the sealing slide plate 178 will open the drain outlet, preventing the drain outlet from being in the open state for a long time. This would prevent bacteria from growing in the water inside the drain outlet and producing an odor. The odor would enter the equipment through the drain outlet and affect the normal use of the equipment.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
