Description

Technical Field

[0001] The present invention relates to the technical field of lathes, in particular to a high-precision CNC turning-milling compound lathe. Background Art

[0002] Combined machining is one of the most popular machining techniques in the world. It's an advanced manufacturing technology that combines several different machining processes on a single machine tool. The most widely used and challenging type of combined machining is turning-milling. A turning-milling machining center is a combination of a CNC lathe and a machining center. Turn-milling machines are the fastest-growing and most widely used CNC equipment among combined machining tools. The integration of machine tools is a key trend in machine tool development.

[0003] For example, an existing patent (publication number: CN213225058U) discloses a CNC lathe for turning and milling composite processing, including a CNC lathe body, an axis column is provided inside the CNC lathe body, a spring is movably connected to the surface of the axis column, one end of the spring is fixedly connected to a connecting wire, one end of the connecting wire is fixedly connected to a movable plate, and a waste trough is provided at the bottom of the movable plate. By arranging the spring and the movable plate, when the processed waste reaches a certain weight, the movable plate automatically tilts to collect the waste into the waste trough.

[0004] However, the CNC lathe for turning and milling compound processing of the above-mentioned design still has some shortcomings in actual use: although the CNC lathe for turning and milling compound processing can use springs and movable plates to make the movable plates reverse when the processing garbage reaches a certain weight, thereby conveniently collecting the garbage into the waste trough, but because some processing garbage is light in weight, the garbage is easy to adhere to the surface of the movable plate, which makes it impossible to pour out the garbage even if the movable plate is reversed, thereby reducing the effect of cleaning up the garbage.

[0005] To this end, we designed a high-precision CNC turning-milling compound lathe to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a high-precision CNC turning-milling compound lathe to solve the problems raised in the above background technology.

The material receiving cavity, the material receiving port and the fixed groove are connected, and a guide is fixedly installed on the bottom wall of the material receiving port at an angle, and one end of the bottom of the guide plate cooperates with the top of the guide.

[0012] Furthermore, storage boxes are fixedly installed on the front and rear sides of the scraper, and lubricating liquid is stored in the storage boxes. Infusion tubes are fixedly installed on the top and bottom of the storage boxes, and a three-way tube is fixedly inserted at the other end of the infusion tube. The other end of the three-way tube extends into the fixed port and abuts against the outer surface of the ball.

[0013] Furthermore, a piston plate is slidably provided in the storage box, two second springs and a piston rod are fixedly installed between the piston plate and the inner wall of the storage box, and the second spring is movably sleeved on the piston rod.

[0014] Furthermore, a material discharge port is provided on the front side of the positioning platform, the material discharge port is communicated with the material receiving cavity, and a material receiving box is slidably inserted into the material discharge port.

[0015] Furthermore, the reset assembly includes an electric push rod, which is fixedly installed on the bottom wall of the fixed groove in the vertical direction. A push block is provided at the driving end of the electric push rod, and the top of the push block is matched and abutted against the bottom of the guide plate. A rotating shaft is fixedly installed on one end of the fixed groove in the horizontal direction, and one side of the guide plate is rotatably sleeved in the rotating shaft.

[0016] Furthermore, two positioning plates are symmetrically fixedly installed on the top of the positioning platform, a cylinder is provided on one side of the positioning plate, the driving end of the cylinder slides through the positioning plate and is provided with an L-shaped piece, and the guide plate is located obliquely below the two L-shaped pieces.

[0017] Compared with the prior art, the beneficial effect of the present invention is that when the gravity of the metal debris falling on the top of the guide plate is greater than the supporting force of the telescopic rod, one end of the guide plate will rotate downward, allowing the metal debris to slide out along the guide plate. During this process, since the guide plate is in an inclined state, the scraper can slide on the guide plate along the direction set by the guide rod, so that the scraper can drive the debris adhered to the surface of the guide plate to actively slide out of the guide plate, thereby improving the cleaning effect of the guide plate and improving the accuracy of cleaning debris from the guide plate.

[0020] Compared with the prior art, the beneficial effect of the present invention is that: through the cooperation of the second spring and the piston rod, the second spring pushes the piston plate to slide in the storage box along the direction of the telescopic end of the piston rod due to its own elastic force, and can actively push the lubricating liquid in the storage box into the infusion tube and the three-way tube, avoiding the problem of being unable to apply due to the lubricating liquid being too viscous.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The present invention provides a technical solution: a high-precision CNC turning and milling compound lathe, comprising a base 1 with a processing unit 2 provided at the top rear end, a positioning platform 3 fixedly installed on the top of the base 1, a fixing slot 4 is provided on the top of the positioning platform 3, a guide plate 5 is rotatably provided in the fixing slot 4, a telescopic rod 6 and a first spring 7 are provided between the guide plate 5 and the inner side wall of the fixing slot 4, two limit plates 8 are symmetrically provided at the end of the top of the guide plate 5, a guide rod 9 is fixedly installed between the two limit plates 8, a scraper 10 is slidingly provided on the top of the guide plate 5, a guide hole 11 is provided in the scraper 10, the scraper 10 is slidably sleeved on the guide rod 9 through the guide hole 11, and a reset component for resetting the guide plate 5 to a horizontal level is provided in the fixing slot 4.

[0025] During specific implementation, after the processing is completed, the metal debris will fall on the top of the guide plate 5. When the gravity of the metal debris is greater than the supporting force of the telescopic rod 6, one end of the guide plate 5 rotates downward, so that the metal debris can slide out along the guide plate 5. During this process, since the guide plate 5 is in an inclined state, the scraper 10 can slide on the guide plate 5 along the direction set by the guide rod 9, so that the scraper 10 can drive the debris adhered to the surface of the guide plate 5 to actively slide out of the guide plate 5, thereby improving the cleaning effect of the guide plate 5 and the accuracy of cleaning the debris from the guide plate 5.

[0026] It should be noted here that the processing unit 2 usually includes components that can be used to drive the drill bit or milling cutter to move horizontally, vertically and rotate, so that the milling cutter or drill bit can perform milling or drilling on the object below. Since the components described above in the processing unit 2 are all existing mature technologies and are not problems that need to be solved in the background technology of this description, they will not be elaborated on.

[0027] See Figure 1-6 There are two guide rods 9, each corresponding to two limit plates 8, and the two guide rods 9 are respectively arranged at the front and rear ends of the top of the guide plate 5. This ensures that the front and rear ends of the scraper 10 are balanced, thereby preventing the scraper 10 from tilting during movement and improving the stability of the scraper 10 during movement.

[0028] See Figure 1-6 Four balls 12 are rotatably arranged at both ends of the scraper 10. Part of the ball 12 is located in the guide hole 11 and is against the guide rod 9. An installation cavity 13 and a fixing port 14 are opened in the scraper 10. The installation cavity 13 and the fixing port 14 are connected. The ball 12 is rotatably arranged in the installation cavity 13 and the fixing port 14, and part of it is located outside the fixing port 14.

[0029] In specific implementation, based on the above implementation, when the scraper 10 slides on the guide rod 9, the guide rod 9 can drive the ball 12 to rotate in the fixing port 14 and the mounting cavity 13, and the sliding friction between the scraper 10 and the guide rod 9 can be changed to rolling friction, thereby reducing the friction force, thereby helping the scraper 10 to slide on the top of the guide plate 5, avoiding the problem of movement resistance due to excessive friction.

[0030] See Figure 1-6 , and also includes a material storage component, which includes a material receiving cavity 15, which is opened in the positioning platform 3, and a material receiving port 16 is also opened in the positioning platform 3. The material receiving cavity 15, the material receiving port 16 and the fixed groove 4 are connected, and a guide 17 is fixedly installed on the bottom wall of the material receiving port 16 at an angle, and one end of the bottom of the guide plate 5 is matched with the top of the guide 17.

[0031] In specific implementation, based on the above implementation, when one end of the bottom of the guide plate 5 abuts against the top of the guide member 17, the metal debris on the top of the guide plate 5 will fall into the receiving cavity 15 along the guide plate 5 and the guide member 17, making it convenient to collect the metal debris.

[0032] See Figure 1-6 Storage boxes 18 are fixedly installed on the front and rear sides of the scraper 10, and lubricating liquid is stored in the storage box 18. Infusion tubes 19 are fixedly installed on the top and bottom of the storage box 18. The other end of the infusion tube 19 is fixedly connected with a three-way tube 20. The other end of the three-way tube 20 extends into the fixed port 14 and abuts against the outer surface of the ball 12.

[0033] In specific implementation, based on the above implementation, during the rotation of the ball 12, the lubricating liquid in the storage box 18 will be evenly applied to the ball 12 through the infusion tube 19 and the three-way pipe 20, which can reduce the friction of the ball 12 in the installation cavity 13 and the fixing port 14, and at the same time reduce the friction between the ball 12 and the guide rod 9, thereby further improving the silky movement effect of the scraper 10 on the guide rod 9.

[0034] It should be noted here that we can set the end of the tee tube 20 away from the infusion tube 19 to be an arc surface, and make the curvature of the arc surface the same as the curvature of the ball 12. This not only reduces the wear between the ball 12 and the tee tube 20 during rotation, but also allows the tee tube 20 to seal the ball 12, preventing the lubricating fluid from leaking from the ball 12, thereby improving the sealing performance.

[0035] See Figure 1-6 A piston plate 21 is slidably provided in the storage box 18 , and two second springs 22 and a piston rod 23 are fixedly installed between the piston plate 21 and the inner wall of the storage box 18 , and the second spring 22 is movably sleeved on the piston rod 23 .

[0036] In specific implementation, on the basis of the above implementation, through the cooperation of the second spring 22 and the piston rod 23, the second spring 22 pushes the piston plate 21 to slide in the storage box 18 along the direction of the telescopic end of the piston rod 23 due to its own elastic force, and can actively push the lubricating liquid in the storage box 18 into the infusion tube 19 and the three-way pipe 20, avoiding the problem of being unable to apply the lubricating liquid due to its excessive viscosity.

[0037] See Figure 1-6 The front side of the positioning platform 3 is provided with a discharge port 24, which is connected to the receiving cavity 15. A receiving box 25 is slidably inserted into the discharge port 24. By pulling the receiving box 25, the receiving box 25 can be pulled out from the discharge port 24, which can facilitate the processing of the metal debris collected in the receiving box 25.

[0038] See Figure 1-6The reset assembly includes an electric push rod 26, which is fixedly installed on the bottom wall of the fixed groove 4 in the vertical direction. A push block 27 is provided at the driving end of the electric push rod 26. The top of the push block 27 is matched with the bottom of the guide plate 5 and abuts against it. A rotating shaft 31 is fixedly installed at one end in the fixed groove 4 in the horizontal direction, and one side of the guide plate 5 is rotatably sleeved in the rotating shaft 31.

[0039] During specific implementation, based on the above implementation, by turning on the electric push rod 26, the driving end of the electric push rod 26 can be extended to drive the push block 27 to move upward, and the push block 27 pushes the guide plate 5 to rotate upward with one end centered on the rotating shaft 31. When one end of the guide plate 5 exceeds the top of the fixed groove 4, the scraper 10 slides and resets along the set direction of the guide rod 9, and finally the guide plate 5 is parallel and stationary, which is convenient for next use. During the whole process, the personnel can control the angle of the guide plate 5 by relying on their own experience and naked eyes.

[0040] See Figure 1-6 Two positioning plates 28 are symmetrically fixedly mounted on the top of the positioning table 3. A cylinder 29 is installed on one side of the positioning plate 28. The driving end of the cylinder 29 slides through the positioning plate 28 and is provided with an L-shaped member 30. The guide plate 5 is located obliquely below the two L-shaped members 30. By placing the object to be processed between the two L-shaped members 30 and then activating the two cylinders 29, the driving ends of the two cylinders 29 extend, driving the L-shaped members 30 until the L-shaped members 30 contact the object, thus stably positioning the object and improving stability during processing.

[0041] Working principle: Before use, we need to connect all the electrical appliances on the base 1 to an external power supply, or install a battery pack in an area outside the base 1 that does not hinder other components, and then connect the battery pack to the electrical appliances through lines. We also need to pay attention to avoid the problem of lines getting entangled due to the movement of the devices. We need to bury the lines and plan and comb them to power the electrical appliances, thereby ensuring the normal operation and switching of the electrical appliances. Since connecting external power supplies to electrical appliances or setting up battery packs to power them are both existing technologies and are not problems that need to be solved in the background technology of this specification, we will not explain them in detail.

[0042] When in use, the object to be processed is placed between the two L-shaped parts 30, and then the two cylinders 29 are turned on. The driving ends of the two cylinders 29 can be extended to drive the L-shaped parts 30 to move until the L-shaped parts 30 are against the object. The object can be stably positioned and then conveniently machined in conjunction with the processing unit 2.

[0043] After the processing is completed, the metal debris will fall on the top of the guide plate 5. When the gravity of the metal debris is greater than the supporting force of the telescopic rod 6, the guide plate 5 rotates one end downward with the rotating shaft 31 as the axis, so that the metal debris can slide along the guide plate 5 into the material receiving chamber 15 for storage. During this process, since the guide plate 5 is in an inclined state, the scraper 10 can slide on the guide plate 5 along the direction set by the guide rod 9, so that the scraper 10 can drive the debris adhered to the surface of the guide plate 5 to actively slide out of the guide plate 5, thereby improving the cleaning effect of the guide plate 5 and the accuracy of cleaning the debris from the guide plate 5.

[0044] It should be noted here that when one end of the bottom of the guide plate 5 is in contact with the top of the guide member 17, the metal debris on the top of the guide plate 5 will fall into the receiving cavity 15 along the guide plate 5 and the guide member 17, which is convenient for collecting the metal debris. By pulling the receiving box 25, the receiving box 25 can be pulled out from the discharge port 24, which can facilitate the processing of the metal debris collected in the receiving box 25.

[0045] By turning on the electric push rod 26, the driving end of the electric push rod 26 can be extended to drive the push block 27 to move upward, and the push block 27 can push the guide plate 5 to rotate upward with one end centered on the rotating shaft 31. When one end of the guide plate 5 exceeds the top of the fixed groove 4, the scraper 10 slides and resets along the set direction of the guide rod 9, and finally makes the guide plate 5 parallel and stationary, which is convenient for next use. During the whole process, the personnel can control the angle of the guide plate 5 by their own experience and naked eyes.

[0046] During the above operation, when the scraper 10 slides on the guide rod 9, the guide rod 9 can drive the ball 12 to rotate in the fixing port 14 and the mounting cavity 13, and the sliding friction between the scraper 10 and the guide rod 9 can be changed to rolling friction, thereby reducing the friction force, thereby helping the scraper 10 to slide on the top of the guide plate 5 and avoiding the problem of movement resistance due to excessive friction.

[0047] In addition, during the rotation of the ball 12, the lubricating liquid in the storage box 18 will be evenly applied to the ball 12 through the infusion tube 19 and the three-way pipe 20, which can reduce the friction of the ball 12 in the installation cavity 13 and the fixing port 14, and at the same time reduce the friction between the ball 12 and the guide rod 9, thereby further improving the silky movement effect of the scraper 10 on the guide rod 9. Through the cooperation of the second spring 22 and the piston rod 23, the second spring 22 pushes the piston plate 21 to slide in the storage box 18 along the direction of the telescopic end of the piston rod 23 due to its own elastic force, and can actively push the lubricating liquid in the storage box 18 into the infusion tube 19 and the three-way pipe 20, avoiding the problem of being unable to apply due to the lubricating liquid being too viscous.
