Description

A multi-angle CNC machining device Technical Field

[0001] This invention belongs to the field of CNC machining technology, specifically a multi-angle CNC machining device. Background Technology

[0002] In CNC machining, universal machine tools play a crucial role in machining complex parts due to their versatility and high precision. During the machining process, the use of coolant is indispensable. It can not only reduce the temperature of the tool and workpiece and prevent overheating deformation, but also play a role in lubrication and chip removal, thereby ensuring machining accuracy and surface quality.

[0003] To achieve efficient resource utilization and meet environmental protection requirements, coolant recycling systems are widely used. These systems filter used coolant through a filter screen to separate impurities such as cutting chips, so that the coolant can be reused.

[0004] However, in practical applications, as processing continues, a large amount of cutting chips accumulate on the filter screen, which can easily cause the filter screen to become clogged. Once the filter screen is clogged, the flow resistance of the coolant increases significantly, the circulation flow rate decreases significantly, and the circulation efficiency is severely reduced.

[0005] A clogged filter can also cause abnormal coolant pressure, affecting the normal operation of the machine tool. In addition, traditional filtration methods often fail to achieve efficient solid-liquid separation, and residual cutting chips accumulate in the filter area, requiring manual cleaning and affecting work efficiency.

[0006] Therefore, the present invention provides a multi-angle CNC machining device. Summary of the Invention

The arc-shaped plate has a cavity inside. The outer wall of the filter plate is flush with the outer wall of the separator. The outer wall of the arc-shaped plate is in contact with the outer wall of the separator. Hard bristles are fixedly installed on the side of the arc-shaped plate near the separator, and an outlet is opened on the arc-shaped plate near the hard bristles.

[0018] Preferably, a threaded rod is rotatably installed on the inner wall of the storage box, and a transmission block is installed on the outer wall of the threaded rod through internal and external thread engagement. A guide rod is fixedly installed on the inner wall of the storage box, and the guide rod passes through the transmission block and is slidably connected to the transmission block.

[0019] A guide block is fixedly installed on the outer wall of the arc plate, a guide frame that is elastically connected to the guide block is fixedly installed on the outer wall of the transmission block, and a guide shaft that is slidably connected to the guide frame is fixedly installed on the outer wall of the guide block.

[0020] Preferably, a connecting frame is fixedly installed on the outer wall of the guide block, and an elastic plate is fixedly installed on the other end of the connecting frame. The inner wall of the elastic plate slides against the outer wall of the guide rod, and a blocking ball is fixedly installed on the outer wall of the guide rod.

[0021] Preferably, a transmission wheel is rotatably mounted on the inner wall of the storage box, the output shaft of the control motor is connected to the transmission wheel through a transmission component, and the axial end of the threaded rod extends to the outer wall of the storage box and is fixedly mounted with a driven wheel that fits against the transmission wheel.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. The various structures of this invention work together to achieve automatic chip removal, significantly improving processing continuity and efficiency. During coolant circulation, the auger rotates forward with the coolant delivery pipe, not only pushing the chips into the separator to prevent them from accumulating on the filter plate and causing blockage, but also scraping the surface of the filter plate to maintain filtration efficiency. When the coolant delivery pipe stops, the auger rotates in the reverse direction, discharging the chips from the separator through the constriction tube. The entire process requires no manual intervention; the chip removal is automatically completed by the forward and reverse rotation of the auger, effectively reducing downtime for cleaning, ensuring smooth processing flow, reducing manual maintenance costs, and improving production efficiency and equipment utilization.

[0027] 2. This invention improves the cleaning effect of the filter plate and the filtration effect of the coolant through the collaborative innovative design of each component. The reciprocating thread of the threaded rod drives the transmission block to slide along the guide rod, and drives the arc plate to reciprocate through the guide frame and spring. Combined with the simple harmonic motion formed by the elastic plate and the blocking ball, the hard bristles penetrate deep into the pores of the filter plate for deep cleaning. At the same time, the extrusion block on the guide block presses against the arc block, driving the extrusion plate to reciprocate to extrude the elastic chamber, so that the coolant is sprayed out from the outlet of the arc plate for backwash cleaning. The two cleaning methods of mechanical brushing and liquid backwashing promote each other, which not only effectively removes cutting chips from the surface and pores of the filter plate, but also enhances the solid-liquid separation effect, ensures efficient recycling of coolant, extends the service life of the processing device, and provides a stable and reliable cooling guarantee for high-precision processing.

Detailed Implementation

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] As shown in Figures 1 to 9, the multi-angle CNC machining device of the present invention includes a working part, a cooling part, a recovery mechanism, a filtering mechanism and a slag discharge mechanism.

[0041] The working section includes a worktable 1, a control arm 5, a chuck 2, and a top pressing table 9. The control arm 5, chuck 2, and top pressing table 9 are all mounted on the worktable 1. The control arm 5 is a CNC robotic arm, and at least two are provided. One movable end is equipped with a drill bit for drilling holes at different angles on the workpiece, and the other movable end is equipped with a milling cutter for milling the surface of the workpiece. The chuck 2 is a rotatable three-jaw chuck that can slide linearly along the upper surface of the worktable 1 to hold the workpiece and simultaneously drive the workpiece (rotary workpiece) to rotate along its own axis. The top pressing table 9 is used to press the workpiece with its top head when the workpiece rotates along its own axis, thereby achieving the spinning process of the workpiece. It integrates drilling, milling, and spinning of the workpiece and is suitable for the processing of rotary workpieces.

[0042] The cooling unit includes a storage tank 12 disposed in the workbench 1 and a shower station 3 disposed on the workbench 1. The shower station 3 is equipped with a nozzle at its front end and can move along the upper surface of the workbench 1 to discharge coolant. During workpiece processing, it washes away cutting chips and cools the workpiece. The inner cavity of the storage tank 12 is used to store coolant and to supply coolant to the shower station 3.

[0043] The recycling mechanism includes a collection hopper 6 and a liquid delivery pipe 10. The collection hopper 6 is fixedly installed on the upper end face of the workbench 1. After the workpiece is fixed, the collection hopper 6 is located directly below the workpiece. When the workpiece is rinsed with coolant, the coolant mixed with cutting chips flows into the interior of the collection hopper 6.

[0044] One end of the infusion pipe 10 is fixedly connected to the bottom surface of the collection hopper 6, and the coolant and cutting chips inside the collection hopper 6 are discharged through the infusion pipe 10.

[0045] The filtration mechanism includes a separation cylinder 17 and a filter plate 16. The separation cylinder 17 is fixedly installed on the inner wall of the storage box 12, and the filter plate 16 is detachably installed on the outer wall of the separation cylinder 17. The filter plate 16 is connected to the separation cylinder 17 by screws, and it is easy to replace and clean the filter plate 16 after removal.

[0046] The bottom of the infusion tube 10 is fixedly connected to the outer wall of the separator 17. The coolant and cutting chips discharged from the infusion tube 10 enter the interior of the separator 17, and then the solid cutting chips are blocked inside the separator 17 by the filter plate 16 to achieve the filtration of coolant. The coolant passing through the filter plate 16 enters the storage tank 12 for return so as to be reused.

[0047] The slag discharge mechanism includes an auger 24 and a constriction tube 7. The constriction tube 7 is fixedly installed at one end of the separation cylinder 17, wherein the transition position between the separation cylinder 17 and the constriction tube 7 is funnel-shaped.

[0048] The auger 24 is rotatably disposed inside the separator 17, wherein one end of the auger 24 extends into the interior of the constriction tube 7, the outer wall of the auger 24 inside the separator 17 is in contact with the inner wall of the separator 17, and the outer wall of the auger 24 located inside the constriction tube 7 is in contact with the inner wall of the constriction tube 7.

[0049] As coolant is introduced into the separator 17 through the infusion pipe 10, the auger 24 rotates in the forward direction, pushing the cutting chips into the separator 17. At the same time, the rotation of the auger 24 can also scrape the surface of the filter plate 16, preventing the filter plate 16 from clogging and maintaining the filtration efficiency of the filter plate 16.

[0050] When the coolant is stopped being delivered by the infusion pipe 10, the auger 24 is rotated in the opposite direction. The auger 24 pushes the cutting chips inside the separator 17 to the constriction pipe 7 and then discharges them. The transition position between the constriction pipe 7 and the separator 17 is designed to create a height difference, using gravity to separate the coolant and cutting chips, and to prevent the coolant from being discharged from the constriction pipe 7.

[0051] In this embodiment, coolant is introduced into the separator 17 through the infusion pipe 10. The forward rotation of the auger 24 can prevent coolant loss as much as possible and further improve the coolant recycling rate.

[0052] A control pump 14 is fixedly installed on the outer wall of the storage tank 12. The control pump 14 is a common micro water pump. The input end of the control pump 14 extends into the inner cavity of the storage tank 12, and the output end of the control pump 14 is connected to the input end of the shower table 3 to provide coolant to the shower table 3.

[0053] The inner wall of the collecting hopper 6 is fixedly installed with a guide plate 8, which is inclined to facilitate the convergence of coolant when collecting coolant.

[0054] A control motor 11 is fixedly installed on the outer wall of the workbench 1. The control motor 11 is a common servo motor. The output shaft of the control motor 11 extends into the inner cavity of the storage box 12 and a control shaft 25 is fixedly installed thereon. A sealed bearing is provided at the contact position between the output shaft of the control shaft 25 and the storage box 12. The control shaft 25 is driven to rotate by the control motor 11.

[0055] The auger 24 is fixedly installed on the radial outer wall of the control shaft 25. When the control shaft 25 rotates, it drives the auger 24 to rotate, thereby cleaning the filter plate 16, preventing coolant from being discharged from the constriction tube 7, and discharging cutting chips.

[0056] In a preferred embodiment of the present invention, a guide rail 23 is fixedly installed on the outer wall of the separating cylinder 17, and an arc plate 18 is slidably installed on the outer wall of the separating cylinder 17 via the guide rail 23. The inner wall of the arc plate 18 is slidably attached to the inner wall of the guide rail 23, thereby realizing the sliding connection between the arc plate 18 and the guide rail 23.

[0057] The arc plate 18 has a cavity inside, the outer wall of the filter plate 16 is flush with the outer wall of the separation cylinder 17, and the outer wall of the arc plate 18 is in contact with the outer wall of the separation cylinder 17, so that when the arc plate 18 slides, it can sweep across the surface of the filter plate 16.

[0058] A rigid brush bristle 31, made of nylon, is fixedly installed on the side of the arc-shaped plate 18 near the separating cylinder 17. An outlet 32 ​​is provided on the arc-shaped plate 18 near the rigid brush bristle 31. When the arc-shaped plate 18 slides, the rigid brush bristle 31 brushes the filter plate 16 to keep the filter plate 16 clean. At the same time, the filtered cleaning liquid is discharged through the outlet 32 ​​to achieve backwash cleaning of the filter plate 16, further improving the cleaning efficiency of the filter plate 16 and thus maintaining the clean permeability of the filter plate 16.

[0059] As the arc plate 18 slides, some of the hard bristles 31 penetrate the filter pores of the filter plate 16, thereby pushing the cutting chips trapped in the pores of the filter plate 16 into the interior of the separation cylinder 17, further improving the cleaning effect of the filter plate 16 and also improving the collection efficiency of cutting chips.

[0060] In this embodiment, when the hard bristles 31 penetrate the gaps in the filter plate 16, coolant is discharged from the outlet 32. The flow of coolant disturbs the hard bristles 31, causing them to vibrate. The vibrating hard bristles 31 are located in the pores inside the filter plate 16, and their interaction further promotes the unblocking efficiency of the filter plate 16 and maintains the filtration effect.

[0061] A threaded rod 27 is rotatably mounted on the inner wall of the storage box 12. A transmission block 30 is mounted on the outer wall of the threaded rod 27 through internal and external thread engagement. The thread on the outer wall of the threaded rod 27 is a reciprocating thread, and the transmission block 30 is connected to the threaded rod 27 through the reciprocating thread.

[0062] A guide rod 35 is fixedly installed on the inner wall of the storage box 12. The guide rod 35 passes through the transmission block 30 and is slidably connected to the transmission block 30. By setting the guide rod 35 to limit the sliding trajectory of the transmission block 30, when the threaded rod 27 rotates, it drives the transmission block 30 to slide back and forth along the outer wall of the threaded rod 27.

[0063] A guide block 29 is fixedly installed on the outer wall of the arc plate 18, and the sliding adjustment of the guide block 29 drives the arc plate 18 to slide.

[0064] A guide frame 33 is fixedly installed on the outer wall of the transmission block 30 and elastically connected to the guide block 29. A spring is provided on the outer wall of the guide frame 33 and connected to the guide block 29. A guide shaft 37 is fixedly installed on the outer wall of the guide block 29 and slidably connected to the guide frame 33. The guide shaft 37 passes through the guide frame 33 and is slidably connected to the guide frame 33. When the transmission block 30 slides, the guide block 29 and the arc plate 18 are driven to slide by the elastic force, thereby realizing the cleaning of the filter plate 16 itself.

[0065] A connecting frame 36 is fixedly installed on the outer wall of the guide block 29. The connecting frame 36 is made of elastic material, and an elastic plate 38 is fixedly installed on the other end of the connecting frame 36. The elastic plate 38 is elastic.

[0066] The inner wall of the elastic plate 38 slides against the outer wall of the guide rod 35. A blocking ball 34 is fixedly installed on the outer wall of the guide rod 35. The blocking ball 34 is used to block the elastic plate 38. As the thrust on the elastic plate 38 increases, the elastic plate 38 deforms and thus passes over the blocking ball 34.

[0067] As the transmission block 30 slides, it drives the guide block 29 to slide until the elastic plate 38 presses against the blocking ball 34. As the transmission block 30 continues to slide, the pushing force (elastic force) of the guide frame 33 on the guide block 29 gradually increases until the elastic plate 38 passes the blocking ball 34. After the elastic plate 38 passes the blocking ball 34, the spring between the guide block 29 and the guide frame 33 resets and performs simple harmonic motion, thereby controlling the synchronous movement of the guide block 29. When the guide block 29 performs simple harmonic motion, the arc plate 18 drives the hard bristles 31 to reciprocate and wash the outer wall of the filter plate 16 in a small range. At the same time, when the hard bristles 31 and the arc plate 18 move synchronously, they move at a constant speed relative to the arc plate 18. The hard bristles 31, which are performing simple harmonic motion, can better insert into the pores of the filter plate 16, promoting each other.

[0068] In a preferred embodiment of the present invention, a transmission wheel 26 is rotatably mounted on the inner wall of the storage box 12. The output shaft of the control motor 11 is connected to the transmission wheel 26 through a transmission component. The transmission component is a belt and a pulley. The control motor 11 controls the rotation of the transmission wheel 26 through the cooperation of the belt and the pulley.

[0069] The axial end of the threaded rod 27 extends to the outer wall of the storage box 12 and is fixedly mounted with a driven wheel 19 that is in contact with the transmission wheel 26. When the transmission wheel 26 rotates, the driven wheel 19 is controlled to rotate by friction (allowing both to slip).

[0070] One end of the driven wheel 19 is fixedly equipped with a limiting ratchet 13, and the outer wall of the storage box 12 is elastically equipped with a limiting ratchet 20 that engages with the limiting ratchet 13. Through the cooperation of the limiting ratchet 13 and the limiting ratchet 20, the rotation direction of the driven wheel 19 and the threaded rod 27 is restricted. When the control motor 11 drives the control shaft 25 to rotate in the forward direction, the threaded rod 27 remains fixed. At this time, the transmission wheel 26 and the driven wheel 19 slip. When the control shaft 25 rotates in the reverse direction, the threaded rod 27 rotates, thereby controlling the arc plate 18 to rotate, so as to filter the coolant on the filter plate 16, reduce the obstruction of the filter surface by the arc plate 18, and improve the filtration and separation efficiency.

[0071] A support frame 21 is fixedly installed on the inner wall of the storage box 12. An elastic chamber 22 is fixedly installed on one side of the support frame 21. The elastic chamber 22 has a one-way output port and an input port. A one-way valve is installed in both the output port and the input port. When the elastic chamber 22 is pressed, the coolant in the elastic chamber 22 is discharged through the output port. When the elastic chamber 22 is released, the elastic chamber 22 returns to its elastic deformation. At this time, coolant from the outside is drawn in through the input port.

[0072] The outlet of the elastic chamber 22 is connected to the inner cavity of the arc plate 18, and the inlet of the elastic chamber 22 is connected to the inside of the storage box 12. Thus, when the elastic chamber 22 is reciprocated, the coolant in the storage box 12 is controlled to be injected into the arc plate 18 and discharged, thereby achieving backflushing cleaning of the filter plate 16.

[0073] A guide pin 4 is fixedly installed on the inner wall of the storage box 12. A compression plate 15 is slidably installed on the outer wall of the guide pin 4 and elastically connected to the inner wall of the storage box 12. The compression plate 15 is used to compress the elastic chamber 22. The compression plate 15 is flush with the elastic chamber 22. The compression plate 15 is pressed back and forth to realize the reciprocating compression of the elastic chamber 22.

[0074] An arc-shaped block 39 is fixedly installed on the outer wall of the extrusion plate 15, and an extrusion block 28 for pressing the arc-shaped block 39 is fixedly installed on the outer wall of the guide block 29. When the arc-shaped block 39 slides, it drives the extrusion block 28 to slide. In conjunction with the elastic force on the extrusion plate 15, the extrusion plate 15 is driven to reciprocate, thereby realizing the reciprocating extrusion of the elastic chamber 22, which is used to control the coolant to be discharged from the outlet 32.

According to the perspective of the observer, the side of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on.
