Description

Technical Field

[0001] This invention relates to the field of CNC machine tools, specifically a five-axis machining center. Background Technology

[0002] Five-axis machining centers, also known as five-axis linkage CNC machine tools, are specifically designed for high-precision machining of complex curved surfaces on workpieces. To prevent the cutting head from overheating during machining, a cooling system is installed inside the machine tool. During the cutting process, flushing fluid is sprayed onto the cutting head. Usually, the machine tool's cabinet door is closed when machining a workpiece, preventing cutting debris and flushing fluid from splashing outside the machine tool.

[0003] Existing Chinese public document (CN113560944A) describes a CNC machine tool with a cleaning structure featuring an observation window. By moving a push block via a handle, the push block drives a slide tube, movable column, mounting base, and cleaning components to move downwards synchronously, with an elastic ball head engaging in a first positioning hole. During downward movement, high-pressure gas first impacts the processing fluid downwards, and then a scraper scrapes away the processing fluid. When the machine reaches contact with the lower support base, the lower support base gradually pushes the mounting base outwards, thereby driving the movable column outwards, and the elastic ball head engages with a second positioning hole. During upward movement, the scraper does not contact the observation window; when it moves to contact the upper support base, the upper support base contacts the movable column and resets. This process is repeated multiple times to achieve cleaning. This allows workers to clean the processing fluid without stopping the machine or opening the cabinet door, ensuring normal observation.

[0004] In the aforementioned published literature, the cleaning component is moved by a guide plate embedded in the first slide groove. However, the first slide groove runs through the cabinet door. With this design, the machining fluid inside the machine tool will be sprayed out of the cabinet door through the first slide groove, causing pollution to the outside of the cabinet door and even spraying onto the workers. Therefore, we propose a five-axis machining center. Summary of the Invention

[0005] The purpose of this invention is to provide a five-axis machining center that can effectively clean the observation window of the machine tool cabinet and prevent machining fluid from spraying outside the cabinet, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a five-axis machining center, comprising a machine tool cabinet and an observation window fixedly embedded inside the machine tool cabinet. A wiping mechanism for wiping and rinsing fluid is provided behind the observation window. The wiping mechanism includes two symmetrically arranged optical axes fixedly mounted on the left and right sides of the observation window via a bracket. Ball bearing sleeves are slidably fitted onto the outer surfaces of both optical axes, and a connecting plate is fixedly installed between the two ball bearing sleeves. A wiping sponge is fixedly fitted onto the outer surface of the connecting plate, and the wiping sponge slidably fits against the rear end face of the observation window. A spring is fixedly installed between the upper part of each ball bearing sleeve and the bracket, and the springs are distributed on the outer side of the optical axis. A counterweight ball is fixedly installed on the outer side of each ball bearing sleeve. The counterweight ball is designed to increase the total weight of the ball bearing sleeve and the connecting plate. A driving mechanism is provided to move the wiping sponge up and down to wipe the observation window. The driving mechanism is installed behind the machine tool cabinet, and a blower mechanism is also provided behind the driving mechanism.

[0007] Preferably, the driving mechanism includes a gear ring rotatably mounted on the rear end face of the machine tool cabinet. A limiting ring is concentrically mounted on the inner side of the gear ring, and the limiting ring is fixedly connected to the machine tool cabinet. A notch is provided at the top of the limiting ring, and an arc-shaped slider is slidably mounted between the gear ring and the limiting ring. A traction rope is fixedly mounted on the inner side of the arc-shaped slider, and the other end of the traction rope is fixedly connected to the connecting plate. The traction rope slides through the notch of the limiting ring. A storage frame plate fixedly connected to the machine tool cabinet is provided below the observation window, and a limiting slot is provided inside the storage frame plate. The rotation of the gear ring can drive the arc-shaped slider to pull the traction rope, causing the wiping sponge to move upward. A locking component is provided between the arc-shaped slider and the gear ring.

[0008] Preferably, the locking assembly includes a positioning arc groove formed on the outer arc surface of the arc-shaped slider. A plurality of round-bottomed locking shafts are radially slidably embedded inside the gear ring. One end of the round-bottomed locking shaft near the center of the gear ring slides through the gear ring, and a spring is fixedly installed between the other end of the round-bottomed locking shaft and the gear ring. The end of the round-bottomed locking shaft near the center of the gear ring is movably engaged with the positioning arc groove. When the round bottom of the round-bottomed locking shaft encounters greater resistance, it will be pushed into the interior of the gear ring by the positioning arc groove.

[0009] Preferably, the arc length between two adjacent round-bottomed pins inside the gear ring is greater than the length of the traction rope, so as to ensure that the connecting plate and the wiping sponge can be pulled upward to the maximum extent by the traction rope.

[0010] Preferably, the bottom of the gear ring is further provided with a transmission assembly, the transmission assembly including a gear one meshing and installed below the gear ring, a motor is fixedly installed at the front end of the machine tool cabinet, and the output end of the motor is rotatably embedded inside the machine tool cabinet, the gear one is fixedly sleeved on the outer surface of the output end of the motor, and the motor drives the gear ring to rotate through the gear one.

[0011] Preferably, the blower mechanism includes a baffle fixedly installed at the top rear end of the machine tool cabinet, and the gear ring is located between the baffle and the machine tool cabinet. The baffle is placed at an angle downwards, and the bottom horizontal plane of the baffle is higher than the top edge of the observation window. A cavity is opened on the upper inner side of the baffle. Several vertical branch slots are also opened inside the baffle. The bottom of the branch slots penetrates through the baffle, and the top of the branch slots communicates with the cavity. An air jet is also provided at the bottom of the branch slots. Inflation components are provided on both the left and right sides of the baffle, and an actuating component is provided between the inflation components and the gear ring. When the inflation components inflate the cavity, the gas is ejected through the air jet. The cooperation of several air jets can form an air curtain behind the observation window.

[0012] Preferably, the inflation assembly includes sealing cylinders installed on the left and right sides of the baffle, and the sealing cylinders are fixedly connected to the machine tool cabinet shell. An air pipe is connected between the upper part of the sealing cylinder and the cavity. A piston push rod is slidably embedded inside the sealing cylinder, and a spring three is provided between the top of the piston push rod and the sealing cylinder. A one-way valve one is fixedly installed on the upper side wall of the sealing cylinder through a branch pipe, and a one-way valve two is fixedly installed on the outside of the air pipe. When the piston push rod moves upward, it can transport the air inside the sealing cylinder into the cavity.

[0013] Preferably, the flow direction of the first one-way valve is one-way flow from the outside to the inside of the sealing cylinder, and the flow direction of the second one-way valve is one-way flow from the sealing cylinder to the branch channel.

[0014] Preferably, the actuation component includes a second gear located at the lower part of the sealing cylinder, and the second gear is rotatably mounted on the back of the machine tool cabinet via a rotating shaft. The second gear is movably meshed with the gear ring. A cam is concentrically fixed at the end of each second gear away from the machine tool cabinet, and the lower end face of the piston push rod slides against the outer surface of the cam. The rotation of the cam, in conjunction with the action of the third spring, enables the piston push rod to reciprocate.

[0015] Preferably, an arc-shaped guide plate is fixedly installed on the rear end face of the baffle, and the two ends of the arc-shaped guide plate are curved downwards.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention designs a wiping sponge on the rear side of the observation window that can both wipe and absorb rinsing liquid. Under the action of the drive mechanism and spring, the wiping sponge can be made to wipe back and forth against the back of the observation window, which can effectively clean the observation window while preventing rinsing liquid from splashing out of the machine tool cabinet.

[0018] 2. By adding a baffle behind the observation window, the present invention allows air to vent from the bottom of the baffle under the action of the transmission component, the touch component, and the inflation component, forming an air curtain, which can reduce the amount of rinsing fluid splashing onto the observation window.

[0030] 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.

[0031] Example 1

[0032] Please see Figures 1-4 The figure shows a five-axis machining center, including a machine tool cabinet 1 and an observation window 2 fixedly embedded inside the machine tool cabinet 1. A wiping mechanism 3 for wiping rinsing fluid is located behind the observation window 2. The wiping mechanism 3 includes two symmetrically arranged optical axes 11 fixedly mounted on the left and right sides of the observation window 2 via brackets. Ball bearing sleeves 12 are slidably fitted onto the outside of each optical axis 11, and a connecting plate 13 is fixedly installed between the two ball bearing sleeves 12. A wiping sponge 14 is fixedly fitted onto the outer surface of the connecting plate 13. 4. The rear end face of the observation window 2 is slidably fitted. A spring 15 is fixedly installed between the upper part of each ball bearing copper sleeve 12 and the bracket. The spring 15 is distributed on the outside of the optical axis 11. A counterweight ball 16 is fixedly installed on the outside of each ball bearing copper sleeve 12. The counterweight ball 16 is designed to increase the total weight of the ball bearing copper sleeve 12 and the connecting plate 13. The drive mechanism 4, which moves the wiping sponge 14 up and down to wipe the observation window 2, is installed at the rear of the machine tool cabinet 1. A blower mechanism 6 is also provided at the rear of the drive mechanism 4.

[0033] Please see Figure 5The driving mechanism 4 shown in the figure includes a gear ring 17 rotatably mounted on the rear end face of the machine tool cabinet 1. A limiting ring 18 is concentrically mounted on the inner side of the gear ring 17, and the limiting ring 18 is fixedly connected to the machine tool cabinet 1. A notch is opened at the top of the limiting ring 18, and an arc-shaped slider 19 is slidably mounted between the gear ring 17 and the limiting ring 18. A traction rope 20 is fixedly mounted on the inner side of the arc-shaped slider 19, and the other end of the traction rope 20 is fixedly connected to the connecting plate 13. The traction rope 20 slides through the notch of the limiting ring 18. A storage frame plate 9 is fixedly connected to the machine tool cabinet 1 below the observation window 2, and a limiting slot 26 is opened inside the storage frame plate 9. The rotation of the gear ring 17 can drive the arc-shaped slider 19 to pull the traction rope 20, so that the wiping sponge 14 moves upward. A locking component is provided between the arc-shaped slider 19 and the gear ring 17.

[0034] Please see Figure 5 and Figure 6 The positioning assembly shown in the figure includes a positioning arc groove 21 opened on the outer arc surface of the arc-shaped slider 19. Several round-bottomed retaining shafts 22 are radially slidably embedded inside the gear ring 17. One end of the round-bottomed retaining shaft 22 near the center of the gear ring 17 slides through the gear ring 17, and a spring 23 is fixedly installed between the other end of the round-bottomed retaining shaft 22 and the gear ring 17. The end of the round-bottomed retaining shaft 22 near the center of the gear ring 17 is movably engaged with the positioning arc groove 21. When the round bottom of the round-bottomed retaining shaft 22 is subjected to greater resistance, it will be pushed into the interior of the gear ring 17 by the positioning arc groove 21.

[0035] Please see Figure 5 and Figure 6 As shown in the figure, the arc length between two adjacent round-bottomed clips 22 inside the gear ring 17 is greater than the length of the traction rope 20, so as to ensure that the connecting plate 13 and the wiping sponge 14 can be pulled upward to the maximum extent through the traction rope 20.

[0036] Please see Figure 5 The bottom of the gear ring 17 in the figure is also provided with a transmission component 5. The transmission component 5 includes a gear 25 meshing and installed below the gear ring 17. The front end of the machine tool cabinet 1 is fixedly installed with a motor 24, and the output end of the motor 24 is rotatably embedded inside the machine tool cabinet 1. The gear 25 is fixedly sleeved on the outer surface of the output end of the motor 24. The motor 24 drives the gear ring 17 to rotate through the gear 25.

[0037] The working principle of the five-axis machine tool that can effectively clean the observation window of the machine tool cabinet and prevent the processing fluid from spraying outside the cabinet is as follows: When the five-axis machine tool is processing the workpiece, the motor 24 can be started. The motor 24 drives the gear ring 17 to rotate through the gear 25. During the rotation of the gear ring 17, it can rotate together with the arc slider 19 through the engagement of the positioning arc groove 21 and the round bottom clamping shaft 22. The arc slider 19 can pull the connecting plate 13 upward through the traction rope 20, so that the connecting plate 13 and the wiping sponge 14 slide upward with the cooperation of the ball copper sleeve 12 and the optical shaft 11. When the traction rope 20 is pulled to the maximum value, the arc slider 19 can no longer follow the gear ring 17. At this time, the continuous rotation of the gear ring 17 will cause the round bottom clamping shaft 22 to disengage from the inside of the positioning arc groove 21 and retract into the inside of the gear ring 17. After the round bottom clamping shaft 22 and the positioning arc groove 21 are separated, the arc slider 19 will no longer be restricted and will quickly retract and reset under the reaction force of the spring 15.

[0038] By moving the wiping sponge 14 back and forth against the back of the observation window 2 in the above manner, the rinsing liquid adhering to the surface of the observation window 2 can be wiped clean. During the downward movement, the connecting plate 13 can also move into the inside of the storage frame plate 9. Under the restriction of the limiting slot 26, the water absorbed by the wiping sponge 14 is squeezed out to facilitate the next absorption and wiping operation.

[0039] Example 2

[0040] Please see Figure 7 This embodiment further explains Example 1. The blower mechanism 6 includes a baffle 27 fixedly installed at the top rear end of the machine tool cabinet 1, and a gear ring 17 located between the baffle 27 and the machine tool cabinet 1. The baffle 27 is placed at an angle downwards, and the bottom horizontal plane of the baffle 27 is higher than the top edge of the observation window 2. A cavity 37 is provided on the upper inner side of the baffle 27. Several vertical branch slots 36 are also provided inside the baffle 27. The bottom of the branch slots 36 penetrates through the baffle 27, and the top of the branch slots 36 communicates with the cavity 37. An air jet is also provided at the bottom of the branch slots 36. Inflation components 7 are provided on both the left and right sides of the baffle 27, and an actuating component 8 is provided between the inflation components 7 and the gear ring 17. When the inflation components 7 inflate the cavity 37, the gas is ejected through the air jet. The cooperation of several air jets can form an air curtain behind the observation window 2.

[0041] Please see Figure 7 , Figure 8 and Figure 9The inflation assembly 7 shown in the figure includes sealing cylinders 28 installed on the left and right sides of the baffle 27. The sealing cylinders 28 are fixedly connected to the machine tool cabinet shell 1. An air pipe 29 is connected between the upper part of the sealing cylinder 28 and the cavity 37. A piston push rod 30 is also slidably embedded inside the sealing cylinder 28. A spring 31 is provided between the top of the piston push rod 30 and the sealing cylinder 28. A one-way valve 32 is fixedly installed on the upper side wall of the sealing cylinder 28 through a branch pipe. A one-way valve 33 is fixedly installed on the outside of the air pipe 29. When the piston push rod 30 moves upward, it can transport the air inside the sealing cylinder 28 into the cavity 37.

[0042] Please see Figure 8 In the diagram, the flow direction of check valve 32 is one-way from the outside to the inside of the sealing cylinder 28, and the flow direction of check valve 33 is one-way from the sealing cylinder 28 to the branch channel 36.

[0043] Please see Figure 8 The trigger component 8 shown in the figure includes a gear 34 located at the lower part of the sealing cylinder 28. The gear 34 is rotatably mounted on the back of the machine tool cabinet 1 via a rotating shaft. The gear 34 is movably meshed with the gear ring 17. A cam 35 is concentrically fixed at the end of each gear 34 away from the machine tool cabinet 1. The lower end face of the piston rod 30 slides against the outer surface of the cam 35. The rotation of the cam 35, in conjunction with the action of the spring 31, enables the piston rod 30 to reciprocate.

[0044] In this embodiment: When the gear ring 17 rotates, it meshes with the gear 2 34, which causes the gear 2 34 to rotate rapidly with the cam 35. Through the cooperation of the cam 35 and the spring 31, the piston rod 30 can move up and down rapidly inside the sealing cylinder 28. At this time, through the action of the one-way valve 1 32 and the one-way valve 2 33, air can be quickly injected into the cavity 37. Finally, it is sprayed out through the branch channel 36 and the jet nozzle, so that an air curtain is formed below the baffle 27, which blows the flushing fluid that is about to splash onto the observation window 2 downward, reducing the amount of flushing fluid that splashes onto the observation window 2.

[0045] Example 3

[0046] Please see Figure 10 This embodiment further illustrates that, for other embodiments, an arc-shaped guide plate 10 is fixedly installed on the rear end face of the baffle 27, and the two ends of the arc-shaped guide plate 10 are curved downwards.

[0047] In this embodiment: under the action of the arc-shaped guide plate 10, the rinsing liquid splashed onto the baffle 27 will only flow to both sides when it flows down, guided by the arc-shaped guide plate 10, that is, the water flow will not affect the line of sight of the observation window 2.
