Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a CNC turning and grinding integrated machine tool. Background Technology

[0002] The CNC turning and grinding integrated machine tool is a composite CNC machining equipment that integrates turning and grinding functions. Based on a vertical structure (spindle perpendicular to the worktable), this equipment is particularly suitable for machining rotating parts such as discs and rings. Multiple processes, including rough turning, finish turning, and precision grinding, can be completed in a single setup, effectively avoiding positioning errors caused by multiple setups in traditional processes, and significantly improving machining accuracy, efficiency, and equipment utilization.

[0003] This lathe mainly consists of a high-rigidity bed, a dual-function spindle system (integrating a turning spindle and a grinding spindle), a high-precision CNC system and servo drive unit, and a composite tool and grinding wheel system. The entire machine is fully automated through the CNC system and can perform various machining tasks such as external cylindrical turning, internal boring, end face turning, as well as precision external cylindrical grinding, internal boring grinding, and surface grinding.

[0004] To ensure operational safety, the outer side of the equipment's workbench is usually equipped with a protective sliding door, through which operators can observe the internal processing status in real time. However, during actual processing, the sliding door is a certain distance from the processing position, and the cutting fluid splashes and adheres to the glass surface after the workpiece and cutting tools rotate at high speed, resulting in a blurred and unclear field of vision, affecting the timely judgment of the processing status, and causing inconvenience to operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a CNC turning and grinding integrated machine tool to solve the problems mentioned in the background technology, enabling the sliding protective door to be moved and adjusted to allow close observation of the workpiece during processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC turning and grinding integrated machine tool, comprising a turning and grinding integrated machine body, a machining platform connected within the turning and grinding integrated machine body, a machining tool connected within the turning and grinding integrated machine body, and two protective doors on the turning and grinding integrated machine body. Each protective door has an installation opening, and a movable structure is slidably connected within the installation opening. The movable structure includes a first movable frame and a second movable frame. The first movable frame is slidably connected to the installation opening, and the second movable frame is slidably connected to the first movable frame.

The cleaning pipe and cleaning brush are located on the inner wall of the protective door and are slidably and vertically arranged with respect to the turning and grinding integrated machine body.

[0007] Furthermore, both sides of the mounting port and the inner wall of the first movable frame are provided with movable grooves, and movable blocks are slidably connected in the movable grooves. Multiple movable blocks are respectively fixedly connected to the outer walls of the corresponding first movable frame and second movable frame.

[0008] Furthermore, a snap-fit ​​component is fixedly connected to the top surface of the inner wall of the second movable frame. The snap-fit ​​component includes a fixing block, a rotating ring is rotatably connected inside the fixing block, a movable shaft is slidably connected inside the rotating ring, a rotating plate is fixedly connected to the outer end of the movable shaft, and a second spring is sleeved on the outer side of the movable shaft. One end of the second spring is fixedly connected to the side wall of the rotating plate, and the other end is fixedly connected to the outer wall of the rotating ring. The outer walls of the second movable frame, the first movable frame, and the protective door are all provided with slots for snapping the rotating plate.

[0009] Furthermore, a U-shaped mounting bracket is fixedly installed on the inner wall of the integrated mill-carrying machine body. The U-shaped mounting bracket consists of two vertical plates and one horizontal plate. A U-shaped plate is fixedly connected to the bottom of the cleaning pipe. The cleaning brush is connected to the U-shaped plate. Limiting rings are fixedly connected to both ends of the U-shaped plate. A downward sliding groove is opened on the inner wall of both vertical plates. A sliding column is fixedly connected in the downward sliding groove. The limiting ring is located in the downward sliding groove and sleeved on the outside of the sliding column. The limiting ring is slidably connected to the sliding column.

[0010] Furthermore, one end of the cleaning pipe is fixedly connected to a water inlet pipe for water intake, and a following groove is provided on the outer wall of the vertical plate located on one side of the water inlet pipe. The following groove is connected to the lower moving groove, the water inlet pipe is located in the following groove and is slidably connected, and a water supply device is connected to the outer end of the water inlet pipe.

[0011] Furthermore, the outer side of the integrated car-grinding machine body is connected to a pulling structure for driving the cleaning pipe to rise and fall. The pulling structure includes two slide rods and two L-shaped rods that are slidably connected to the integrated car-grinding machine body. The two slide rods are fixedly connected to the top surface of the outer wall of the cleaning pipe. The outer ends of the two slide rods pass through the outer shell of the integrated car-grinding machine body and are fixedly connected to the L-shaped rods. A connecting rod is fixedly connected between the two L-shaped rods. The connecting rod is located on the side away from the slide rods. The connecting rod and the two L-shaped rods are slidably connected to the outer wall of the integrated car-grinding machine body. The outer walls of the two L-shaped rods are connected to elastic elements.

[0012] Furthermore, the elastic element includes a first plate and a second plate. The first plate is fixedly installed on the top surface of the integrated milling and turning machine body. A limiting post is fixedly connected to the top surface of the first plate. A first spring is sleeved on the outer side of the limiting post. One end of the first spring is fixedly connected to the top surface of the first plate, and the other end is fixedly connected to the bottom surface of the second plate. The second plate is fixedly connected to the outer wall of the L-shaped rod. The limiting post passes through the second plate and is slidably connected to the second plate.

[0013] Furthermore, an insert plate is inserted into the outside of the connecting rod. The insert plate passes through the connecting rod and is inserted into the outer shell of the integrated mill and car body. The cross-section of the insert plate is L-shaped.

[0014] Furthermore, the outer side of the downward groove of the inner wall of the two vertical plates is connected to a bellows plate for protection. One end of the bellows plate is fixedly connected to the bottom wall of the downward groove, and the other end is fixedly connected to the bottom surface of the U-shaped plate.

[0015] Furthermore, the U-shaped plate has an insertion groove, into which an L-shaped plate is inserted. The cleaning brush is fixedly connected to the L-shaped plate. Several top plates are fixedly connected to the top surface of the U-shaped plate. Screws are threaded onto the top plates, and the screws pass through the top plates and are threadedly connected to the L-shaped plates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of CNC turning and grinding machine tool, by adding a movable viewing window to the originally fixed protective door, along with a cleaning pipe and brush, can effectively remove impurities adhering to the window. The viewing window can then be pushed forward towards the workpiece, allowing the operator to observe the workpiece's machining status more clearly and in detail. This design solves the problems of traditional protective doors being too far from the workpiece and having blurred vision due to cutting fluid adhesion, thus improving the practicality and ease of operation of the turning and grinding machine.

[0017] 2. This type of CNC turning and grinding integrated machine tool, through the setting of the connecting rod, allows the operator to easily pull the connecting rod to drive the L-shaped rod and slide rod to descend, thereby lowering the cleaning tube. The U-shaped plate is used to connect the cleaning tube and the cleaning brush. With the cooperation of the limiting rings and sliding columns at both ends of the U-shaped plate, the lifting and lowering of the cleaning tube and the cleaning brush is stable. The cooperation of the first spring, the limiting column and the second plate makes the reset of the cleaning tube simple and convenient. When the cleaning tube is not in use, it is always in a high position inside the turning and grinding integrated machine body, effectively reducing the chance of being splashed by cutting fluid.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figure 1 - Figure 9 A CNC turning and grinding integrated machine tool includes a turning and grinding integrated machine body 1, a machining platform 2 connected inside the turning and grinding integrated machine body 1, a machining tool 4 connected inside the turning and grinding integrated machine body 1, and two protective doors 3 on the turning and grinding integrated machine body 1. The protective doors 3 have installation openings 15, and a movable structure is slidably connected inside the installation openings 15. The movable structure includes a first movable frame 16 and a second movable frame 17. The first movable frame 16 is slidably connected to the installation openings 15, and the second movable frame 17 is slidably connected to the first movable frame 16. A viewing glass window 18 is fixedly connected inside the second movable frame 17. A cleaning structure for cleaning the inner wall of the protective doors 3 is connected to the inner wall of the turning and grinding integrated machine body 1. The cleaning structure includes a cleaning pipe 30 and a cleaning brush 14. Multiple nozzles 34 are fixedly connected to the outer wall of the cleaning pipe 30. The cleaning pipe 30 and the cleaning brush 14 are located on the inner wall of the protective doors 3 and are slidably raised and lowered with the turning and grinding integrated machine body 1.

[0022] In the CNC turning and grinding integrated machine tool of the present invention, when the machining tool 4 in the machine body 1 is turning or grinding the workpiece on the machining platform 2, in order to ensure machining safety, the two protective doors 3 are closed. At this time, the cutting fluid will splash onto the inner wall of the two protective doors 3. At this time, the operable lifting cleaning pipe 30 and cleaning brush 14 clean and scrub the inner wall of the protective door 3, remove the adhering impurities, and push the first moving frame 16 and the second moving frame 17 to move, so that the second moving frame 17 moves horizontally on the first moving frame 16. The first moving frame 16 moves in the mounting port 15, thereby causing the viewing glass window 18 on the second moving frame 17 to move closer to the position of the machining platform 2.

[0023] The cleaning pipe 30 and nozzle 34 descend from the top of the protective door 3, rinsing the inner wall of the protective door 3 with cleaning water. At the same time, the cleaning brush 14 also descends, sweeping away the attached impurities to achieve a good cleaning effect. The cleaned viewing glass window 18 can then be pushed forward by the first moving frame 16 and the second moving frame 17 moving within the mounting port 15, so that the viewing glass window 18 is close to the processing tool 4 and workpiece on the processing platform 2. This allows for a more detailed observation of the workpiece's processing status.

[0024] In actual use, the second moving frame 17 cannot completely fit with the machining tool 4 and the workpiece when it moves forward or backward. It only gets close to the machining tool 4 and the workpiece, which makes it easier to observe in more detail and avoids the occurrence of tool collision. The multi-segment movement of the viewing glass window 18 is realized by the nested first moving frame 16 and the second moving frame 17, which makes the movement distance more controllable and improves safety.

[0025] In addition, both protective doors 3 can be equipped with a movable viewing window 18, making them more flexible in use; under normal circumstances, the protective door 3 itself is also equipped with a viewing window for easy observation.

[0026] By installing a movable viewing glass window 18 on the originally fixed protective door 3, and using the cleaning pipe 30 and cleaning brush 14, the adhering impurities are cleaned. The viewing glass window 18 is then pushed closer to the workpiece, making it easier to observe the workpiece's processing status in more detail and clearly. This solves the problem that the original protective door 3 was far from the workpiece and that the cutting fluid made it difficult to see, effectively improving the practicality of the turning and grinding machine body 1.

[0027] As a preferred embodiment of the present invention, both sides of the inner wall of the mounting port 15 and the first moving frame 16 are provided with moving grooves 21, and moving blocks 22 are slidably connected in the moving grooves 21. Multiple moving blocks 22 are respectively fixedly connected to the outer walls of the corresponding first moving frame 16 and second moving frame 17.

[0028] Specifically, when the first moving frame 16 and the second moving frame 17 move forward or backward, the moving block 22 on the outer wall of the first moving frame 16 moves within the moving groove 21 on the inner wall of the mounting opening 15, and the moving block 22 on the outer wall of the second moving frame 17 moves within the moving groove 21 on the inner wall of the first moving frame 16. This arrangement allows the viewing glass window 18 to move stably during movement. In the retracted state, the second moving frame 17, the first moving frame 16, and the viewing glass window 18 can be retracted and overlapped within the mounting opening 15, making it convenient for the protective door 3 to be pushed and pulled open to enter the interior of the integrated car and mill machine body 1, ensuring that the arrangement of the first moving frame 16 and the second moving frame 17 does not affect the function of the protective door 3 itself.

[0029] As a preferred embodiment of the present invention, a snap-fit ​​component is fixedly connected to the top surface of the inner wall of the second movable frame 17. The snap-fit ​​component includes a fixing block 24, a rotating ring 26 is rotatably connected inside the fixing block 24, a movable shaft 25 is slidably connected inside the rotating ring 26, a rotating plate 19 is fixedly connected to the outer end of the movable shaft 25, and a second spring 27 is sleeved on the outer side of the movable shaft 25. One end of the second spring 27 is fixedly connected to the side wall of the rotating plate 19, and the other end is fixedly connected to the outer wall of the rotating ring 26. The outer walls of the second movable frame 17, the first movable frame 16, and the protective door 3 are all provided with a snap-fit ​​groove 23 for snapping the rotating plate 19.

[0030] Specifically, in order to keep the first moving frame 16 and the second moving frame 17 stable when not in use, the rotating plate 19 in the snap-fit ​​can be pulled first, causing the rotating plate 19 and the moving shaft 25 to slide within the rotating ring 26. At this time, the second spring 27 is stretched. When the position of the rotating plate 19 after being pulled has exceeded the outer wall of the protective door 3, the rotating plate 19 is rotated, causing the rotating plate 19, the moving shaft 25, the second spring 27 and the rotating ring 26 to rotate within the fixed block 24. After the rotating plate 19 rotates, it will correspond to the slot 23. Then the rotating plate 19 is released. Under the action of the elastic potential energy of the second spring 27, the rotating plate 19 is pulled back by the second spring 27, causing the moving shaft 25 to move and reset within the rotating ring 26. Under the action of the second spring 27, the rotating plate 19 can be firmly snapped into the slot 23. This ensures that the second moving frame 17 is limited on the protective door 3, while the rotating plate 19 and the slot 23 are in an embedded state, ensuring that the protective door 3 is not affected when it is pushed, pulled or retracted.

[0031] As a preferred technical solution of the present invention, a U-shaped mounting bracket is fixedly installed on the inner wall of the grinding machine body 1. The U-shaped mounting bracket consists of two vertical plates 10 and a horizontal plate 28. A U-shaped plate 29 is fixedly connected to the bottom of the cleaning pipe 30. The cleaning brush 14 is connected to the U-shaped plate 29. Limiting rings 37 are fixedly connected to both ends of the U-shaped plate 29. A downward groove 32 is opened on the inner wall of both vertical plates 10. A sliding column 33 is fixedly connected in the downward groove 32. The limiting ring 37 is located in the downward groove 32 and sleeved on the outside of the sliding column 33. The limiting ring 37 is slidably connected to the sliding column 33.

[0032] Specifically, when the cleaning pipe 30 needs to be raised or lowered, since both the cleaning pipe 30 and the cleaning brush 14 are slidably connected to the vertical plate 10 via the U-shaped plate 29, the raising and lowering of the cleaning pipe 30 and the cleaning brush 14 is accomplished by raising and lowering the U-shaped plate 29.

[0033] When the U-shaped plate 29 is raised or lowered, the limiting rings 37 at both ends of the U-shaped plate 29 slide outside the sliding column 33 in the downward groove 32 of the vertical plate 10. The cooperation of the two limiting rings 37 and the sliding column 33 makes the raising and lowering of the U-shaped plate 29 stable.

[0034] As a preferred technical solution of the present invention, one end of the cleaning pipe 30 is fixedly connected to a water inlet pipe 35 for water inlet, and a following groove 31 is provided on the outer wall of the vertical plate 10 located on one side of the water inlet pipe 35. The following groove 31 is connected to the lower moving groove 32. The water inlet pipe 35 is located in the following groove 31 and is slidably connected. A water supply device is connected to the outer end of the water inlet pipe 35.

[0035] Specifically, the water inlet of the cleaning pipe 30 is supplied by an external water supply device connected to the water inlet pipe 35. The cleaning pipe 30 is hollow inside, so that multiple nozzles 34 can spray clean water. The water supply device can be a high-pressure pump, water tank, filter, safety valve, pressure regulating valve, etc. The above are all common knowledge and will not be described in detail here.

[0036] When the cleaning pipe 30 is raised or lowered, its end, along with the water inlet pipe 35, moves up and down within the following trough 31. The water inlet pipe 35 needs to have a certain redundancy to ensure that the length of the water inlet pipe 35 is not obstructed or restricted when the cleaning pipe 30 is raised or lowered.

[0037] As a preferred embodiment of the present invention, the outer side of the integrated car-grinding machine body 1 is connected to a pulling structure for driving the cleaning pipe 30 to rise and fall. The pulling structure includes two slide rods 6 and two L-shaped rods 5 that are slidably connected to the body of the integrated car-grinding machine body 1. The two slide rods 6 are fixedly connected to the top surface of the outer wall of the cleaning pipe 30. The outer ends of the two slide rods 6 pass through the outer shell of the integrated car-grinding machine body 1 and are fixedly connected to the L-shaped rods 5. A connecting rod 11 is fixedly connected between the two L-shaped rods 5. The connecting rod 11 is located on the side away from the slide rods 6. The connecting rod 11 and the two L-shaped rods 5 are slidably connected to the outer wall of the integrated car-grinding machine body 1. The outer walls of the two L-shaped rods 5 are connected to elastic elements.

[0038] Specifically, to facilitate the operation of the cleaning pipe 30 and cleaning brush 14 during descent, when the cleaning pipe 30 needs to be lowered for cleaning, the connecting rod 11 can be pulled to move the two L-shaped rods 5 downwards on the outer side of the machine body 1 of the integrated mill and car body. After the L-shaped rods 5 move downwards, the sliding rod 6 is lowered, pushing the cleaning pipe 30 downwards, which in turn lowers the U-shaped plate 29 and the cleaning brush 14. When the U-shaped plate 29 is lowered, the limiting rings 37 on both sides of the U-shaped plate 29 slide downwards on the outer side of the sliding column 33. Before the cleaning pipe 30 is lowered, the external water supply equipment needs to be started so that the cleaning water enters the cleaning pipe 30 from the water inlet pipe 35 and sprays out from the nozzle 34, and then rinses the protective door 3.

[0039] As a preferred technical solution of the present invention, the elastic element includes a first plate 7 and a second plate 12. The first plate 7 is fixedly installed on the top surface of the machine body 1. A limiting post 8 is fixedly connected to the top surface of the first plate 7. A first spring 9 is sleeved on the outer side of the limiting post 8. One end of the first spring 9 is fixedly connected to the top surface of the first plate 7, and the other end is fixedly connected to the bottom surface of the second plate 12. The second plate 12 is fixedly connected to the outer wall of the L-shaped rod 5. The limiting post 8 passes through the second plate 12 and is slidably connected to the second plate 12.

[0040] Specifically, when the L-shaped rod 5 descends, it drives the second plate 12 to descend, causing the second plate 12 to compress the first spring 9 and slide downwards on the outside of the limiting post 8. The first spring 9 is compressed, the L-shaped rod 5 descends, and the slide rod 6 descends. When the cleaning tube 30 rises, under the action of the elastic potential energy of the first spring 9, it pushes the second plate 12, causing the L-shaped rod 5 to reset, the slide rod 6 to reset, and the cleaning tube 30 to reset.

[0041] The connecting rod 11 allows the operator to easily pull it to lower the L-shaped rod 5 and the sliding rod 6, thus lowering the cleaning tube 30. The U-shaped plate 29 connects the cleaning tube 30 and the cleaning brush 14. With the cooperation of the limiting rings 37 and the sliding column 33 at both ends of the U-shaped plate 29, the lifting and lowering of the cleaning tube 30 and the cleaning brush 14 are stable. The cooperation of the first spring 9, the limiting column 8, and the second plate 12 makes the reset of the cleaning tube 30 simple and convenient. When the cleaning tube 30 is not in use, it is always in a high position inside the body 1 of the turning and grinding machine, effectively reducing the chance of being splashed by cutting fluid.

[0042] As a preferred technical solution of the present invention, a plug plate 13 is inserted into the outside of the connecting rod 11. The plug plate 13 passes through the connecting rod 11 and is inserted into the outer shell of the machine body 1 of the integrated car and mill. The cross-section of the plug plate 13 is L-shaped.

[0043] Specifically, the insertion plate 13 is designed to always limit the high position of the connecting rod 11 to this position, preventing the elastic potential energy of the first spring 9 from being lost and thus failing to maintain the high position. The L-shaped insertion plate 13 allows the connecting rod 11 to be easily pulled out before the pulling operation.

[0044] As a preferred technical solution of the present invention, a bellows plate 20 for protection is connected to the outer side of the downward groove 32 of the inner wall of the two vertical plates 10. One end of the bellows plate 20 is fixedly connected to the bottom wall of the downward groove 32, and the other end is fixedly connected to the bottom surface of the U-shaped plate 29.

[0045] Specifically, when the U-shaped plate 29 is raised or lowered, it causes the bellows plate 20 to be compressed and unfolded. The bellows plate 20 effectively prevents impurities from entering the lower sliding groove 32.

[0046] As a preferred technical solution of the present invention, a U-shaped plate 29 is provided with an insertion groove 38, an L-shaped plate 36 is inserted into the insertion groove 38, the cleaning brush 14 is fixedly connected to the L-shaped plate 36, and a plurality of top plates 39 are fixedly connected to the top surface of the U-shaped plate 29. The top plates 39 are threadedly connected with screws 40, and the screws 40 pass through the top plates 39 and are threadedly connected to the L-shaped plates 36.

[0047] Specifically, after the cleaning brush 14 has been used for a period of time, the screw 40 can be removed to free the L-shaped plate 36 from its restriction. Then, the L-shaped plate 36 can be removed from the insertion slot 38 in the U-shaped plate 29, which makes it easier to replace the cleaning brush 14 and ensures the cleaning effect.

[0048] 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 alterations 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.
