[0038] 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.

[0039] like Figures 1 to 8 As shown in the embodiment of the present invention, an automatic tool changing device for vertical five-axis linkage composite machining includes:

[0040] Vertical 5-axis machining center 1,

[0041] The driver 11 is mounted on the vertical five-axis machining center 1 described above via a five-axis moving assembly;

[0042] The barrier plates 12 are a pair and are symmetrically fixed to the two side walls of the above-mentioned vertical five-axis machining center 1.

[0043] The opening and closing plates 13 are a pair and are symmetrically slidably connected to the side wall of the above-mentioned barrier plate 12 by a motor.

[0044] The machining table 17 is fixedly connected to the center of the bottom of the above-mentioned vertical five-axis machining center 1.

[0045] Pull-out plates 14, there are a pair of pull-out plates 14, and they are slidably connected to the top of the processing table 17 located away from the above-mentioned barrier plate 12;

[0046] Spindle 15 is fixedly attached to the bottom of the aforementioned driver 11;

[0047] Machining tools 16 are installed at the bottom of the spindle 15, and there are multiple sets of machining tools 16, all located on the top of the pull-out plate 14. During normal machining in the vertical five-axis machining center 1, as the types of parts are replaced and the machining processes differ, the spindle 15 needs to be replaced with different types of machining tools 16. At this time, the five-axis moving assembly above the driver 11 drives the entire driver 11 to move. Under the drive of the motor, the opening and closing plate 13 moves to both sides, allowing the driver 11 to smoothly enter the pull-out plate 14. According to the usage requirements, the multiple sets of machining tools 16 on the pull-out plate 14 are installed and replaced, and then moved to the zero part. The cutting is performed at the location of the workpiece, while the opening and closing plate 13 closes to keep the flying debris during the cutting process away from the pull plate 14. By utilizing the movement effect of the five-axis moving component, the driver 11 can be driven to bring the spindle 15 above the machining tool 16 for installation as needed, reducing the tedious operation of manual assembly. At the same time, the movable effect of the pull plate 14 makes it easy for operators to place and replace a large number of machining tools 16, increasing the portability of installation. Furthermore, the sealing effect of the opening and closing plate 13 and the barrier plate 12 can keep the debris during the machining process within the machining area, reducing the possibility of it entering between the pull plate 14 and the machining tool 16.

[0048] like Figures 1 to 8As shown, the spindle 15 has a first groove 2 at its bottom; the machining tool 16 has a positioning block 21 mounted on its top; the positioning block 21 has second grooves 22 on both sides of its sidewalls; a clamping plate 24 is slidably connected to the sidewalls of the first groove 2 and the second groove 22 at corresponding positions; an electric push rod 25 is driven by a motor at the middle of the spindle 15 above the clamping plate 24, and the electric push rod 25 controls the movement of the clamping plate 24 by moving; guide rails 23 are fixed to both sides of the positioning block 21, and grooves are formed on the sidewalls of the first groove 2 and the guide rails 23 at corresponding positions; during the normal operation of the vertical five-axis machining center 1, different processing is required depending on the type of parts and the different processing needs. When the machining tool 16 is replaced, the spindle 15 can be moved to the side of the machining tool 16 under the movement of the driver 11. The first slide 2 is opened and the positioning block 21 is inserted accordingly. The clamping effect provided by the electric push rod 25 causes the clamping plate 24 to be inserted into the second slide 22, thus fixing the machining tool 16. The positioning block 21 installed on the top of the machining tool 16 can be inserted into the first slide 2 opened at the bottom of the spindle 15 to maintain the tight connection between the two. At the same time, the clamping plate 24 restricts the second slide 22, increasing the installation efficiency between the machining tool 16 and the spindle 15 and reducing the cumbersome installation of the traditional threaded connection machining tool 16.

[0049] like Figures 1 to 8 As shown, the positioning block 21 has a third sliding groove 3 on its side wall; a limiting rod 31 is fixedly connected to the inner side wall of the third sliding groove 3; limiting posts 32 are slidably connected to both sides of the limiting rod 31; grooves are provided at corresponding positions on the side wall of the first sliding groove 2 and the limiting posts 32; anti-detachment blocks 34 are fixedly connected to both sides of the limiting rod 31; a rubber pad 33 is slidably connected to the middle of the limiting post 32; after the installation steps are completed between the machining tool 16 and the positioning block 21, during the cutting process, as the rotation speed increases, the limiting post 32 will move to both sides of the limiting rod 31 under the action of centrifugal force. The limiting post 32 will enter the corresponding groove inside the first slide groove 2 to maintain the connection between the spindle 15 and the positioning block 21. At the same time, during the movement of the limiting post 32, the anti-detachment block 34 will contact the rubber pad 33 and push the rubber pad 33 to fit into the groove of the first slide groove 2. Through the centrifugal force generated by the rotation, the limiting post 32 can be moved to both sides of the limiting rod 31, thereby increasing the contact area and fixing effect between the spindle 15 and the positioning block 21, reducing the possibility of detachment during rotation, and increasing the stability of the machining tool 16 during the cutting process.

[0050] like Figures 1 to 8As shown, multiple sets of positioning rings 4 are installed on the top of each of the aforementioned pull-out plates 14; a fourth slide groove 41 is opened through the top of each pull-out plate 14 at the location of each set of positioning rings 4; a cross plate 42 is fixedly connected to the middle of the fourth slide groove 41; the bottom of the positioning rings 4 is fixedly connected to the top of the cross plate 42; a fifth slide groove 43 is opened on the top surface of the pull-out plate 14 below the pull-out plate 14; multiple sets of fans 44 are installed inside the fifth slide groove 43; during normal use of the vertical five-axis machining center 1, when dealing with different types of parts, it is necessary to change the machining tool 16. At this time, during the cutting process, some metal impurities adhere to some sidewalls of the replaced machining tool 16. After the cutting tool 16 is placed inside the positioning ring 4, the fan 44 installed inside the fifth slide 43 operates normally, generating an upward airflow. The airflow is kept connected to the positioning ring 4 through the fourth slide 41. The airflow cleans the surface of the cutting tool 16. The positioning ring 4 provides a restraining effect, keeping the cutting tool 16 in a stable position. At the same time, the fan 44 installed below the pull plate 14 generates an upward airflow to blow on the surface of the cutting tool 16, reducing the retention of metal impurities on the surface of the cutting tool 16. This reduces the risk of the cutting tool 16 falling off due to improper installation position caused by impurities when it is replaced later.

[0051] like Figures 1 to 8As shown, the top sidewall of the positioning ring 4 is slidably connected to multiple sets of push blocks 5; the corresponding sidewalls of the multiple sets of push blocks 5 are all inclined; the bottom sidewall of the positioning ring 4 is rotatably connected to multiple sets of side plates 51 via torsion springs; the sidewalls of the multiple sets of side plates 51 and the middle of the positioning ring 4 are rotatably connected to a first rotating shaft 52; one end of a braided belt 53 is fixedly connected to the first rotating shaft 52 on the sidewall of the side plate 51, and the other end of the braided belt 53 passes through the first rotating shaft 52 in the middle and is fixedly connected to the bottom of the push block 5; a pressing column 54 is fixedly connected between the machining tool 16 and the positioning block 21; during the process of inserting different types of machining tools 16 into the positioning ring 4, as the bottom of the pressing column 54 gradually contacts the multiple sets of push blocks 5, at this time, by utilizing the inclination angle generated by the sidewall of the push block 5, the pressing column 54 can be made to... The resulting downward squeezing force causes the pusher block 5 to move outward from the positioning ring 4, thereby causing the braided belt 53 to contract and pull the side plate 51 outward to open, leaving a gap. Under the blowing of the subsequent rising airflow, the gap left by the opening of the side plate 51 increases the airflow channel, making it easier for impurities cut off from the side wall of the machining tool 16 to be discharged from inside the positioning ring 4. Through the multiple sets of pusher blocks 5 installed on the side wall of the positioning ring 4, the position of the machining tool 16 can be kept centered during the placement of the machining tool 16. At the same time, after the machining tool 16 is placed, the movement of the pusher block 5 causes the side plate 51 to rotate and open, which facilitates airflow and reduces the retention of impurities on the side wall of the machining tool 16 inside the positioning ring 4, thus affecting the insertion and removal of the machining tool 16.

[0052] like Figures 1 to 8 As shown, a rack 6 is fixedly connected to both the upper and lower sides of the sidewalls of the aforementioned opening and closing plates 13; a linkage rod 61 is rotatably connected to the sidewall of the aforementioned blocking plate 12; the linkage rod 61 and the rack 6 are connected by gear meshing; a rack 62 is slidably connected to the bottom of the linkage rod 61 inside the pull-out plate 14; the rack 62 and the end of the linkage rod 61 are connected by bevel gear meshing; a baffle plate 63 is fixedly connected to the sidewall of the rack 62; the baffle plate 63 slides inside the fifth slide groove 43; during the opening and closing movement of the opening and closing plates 13, as the opening and closing plates 13 move, the linkage rod 61 will rotate through the rack 6, at which time, the linkage... The meshing connection between rod 61 and rack 62 can cause rack 62 to move, causing the opening and closing plate 13 to push the baffle plate 63 to the position of slide 43 in the open and closed state, covering the top of slide 43 and blocking the upward airflow generated by fan 44. Through the movement of the opening and closing plate 13, while blocking the flying debris, rack 62 is moved, which in turn causes rack 62 to drive baffle plate 63 to close slide 43. This reduces the generation of upward airflow during the change of different types of machining tools 16 on the spindle 15, and reduces the impact of airflow on the change of machining tools 16.

[0053] like Figures 1 to 8 As shown, multiple sets of the aforementioned second racks 62 are fixedly connected to positioning plates 7 on both sides inside the pull-out plate 14; multiple sets of impact plates 71 are hinged to both side walls of the aforementioned second racks 62 by torsion springs, and the ends of the impact plates 71 are spherical; multiple sets of sixth sliding grooves 72 are opened on the side walls of the positioning plates 7 near the second racks 62, and the sixth sliding grooves 72 are semi-circular; during the process of the second racks 62 moving after the opening and closing plate 13 opens and closes, the movement of the baffle plate 63 will cause the multiple sets of impact plates 71 to contact the ends of the positioning plates 7 side walls, through Multiple sets of No. 6 sliding grooves 72 are opened on the side wall of multiple sets of positioning plates 7. During the movement of the impact plate 71, the impact plate 71 continuously contacts the No. 6 sliding grooves 72, causing a jerking motion. Through the movement effect of the No. 2 rack 62, a vibration effect can be generated during the movement by driving the impact plate 71 to continuously contact the multiple sets of No. 6 sliding grooves 72. At this time, the vibration generated by the collision can be transmitted to the surface of the pull plate 14, loosening the cut waste material and reducing the waste material adhering to the surface of the pull plate 14 due to high temperature residue during processing.

[0054] like Figures 1 to 8 As shown, each of the aforementioned positioning plates 7 has a seventh sliding groove 8 on its sidewall away from the second rack 62; a slider 81 is slidably connected inside the seventh sliding groove 8; a support rod 82 is fixed between the sidewall of the slider 81 and the sidewall of the shield 63; during the opening and closing of the opening and closing plate 13, as the second rack 62 moves, the shield 63 will move as a whole. At this time, the support rod 82 installed on the sidewall of the shield 63 can drive the slider 81 to move inside the seventh sliding groove 8. Through the overall limiting effect of the positioning plate 7 and the seventh sliding groove 8, the shield 63 is kept stable during its movement. Through the triangular area formed by the shield 63, the positioning plate 7, and the support rod 82, the stability of the shield 63 during its movement can be maintained, reducing the deviation that occurs during the movement of the shield 63 and increasing the fit between the shield 63 and the fifth sliding groove 43 after multiple movements.

[0055] like Figures 1 to 8As shown, multiple sets of air ducts 9 are fixed to the side wall of the cross plate 42. The air ducts 9 float inside the positioning ring 4 and contact the side wall of the machining tool 16. During the storage of the machining tool 16 inside the positioning ring 4, as the opening and closing plate 13 closes, the baffle plate 63 retracts to the fifth slide groove 43 and is exposed. The upward blowing force causes the air ducts 9 to float inside the positioning ring 4, which beats the metal impurities cut from the machining tool 16 and allows the impurities to be discharged smoothly. By using the multiple sets of air ducts 9 installed on the side wall of the cross plate 42, when the machining tool 16 is placed inside the positioning ring 4 after processing, the upward airflow generated by the fan 44 causes the air ducts 9 to float inside the positioning ring 4 and contact the side wall of the machining tool 16, which beats the metal waste remaining on the machining tool 16 during the cutting process and discharges it through the airflow, keeping the overall cleanliness of the machining tool 16.

[0056] like Figures 1 to 8 As shown, each of the above-mentioned positioning rings 4 has an eighth slide groove 101 on its top, and the eighth slide groove 101 is set at an inclination. During the placement of different types of machining tools 16, the eighth slide groove 101 on the top of the positioning ring 4 can guide the machining tool 16 to smoothly enter the positioning ring 4 for placement by its own inclination angle. At the same time, the inclination angle of the eighth slide groove 101 can correspond to the inclination angle of the push block 5, so that the machining tool 16 has a centered position during the insertion process. Through the eighth slide groove 101 on the top of the positioning ring 4, it can cooperate with the inclination angle of the side wall of the push block 5 to assist different types of spindles 15 to enter smoothly and reduce the occurrence of jamming.

[0057] During normal operation of the vertical five-axis machining center 1, as the types of parts change and the processing technology varies, the spindle 15 needs to be replaced with different types of cutting tools 16. At this time, the five-axis moving assembly above the driver 11 drives the entire driver 11 to move. Under the drive of the motor, the opening and closing plate 13 moves to both sides, allowing the driver 11 to smoothly enter the upper part of the pull plate 14. According to the usage requirements, multiple sets of cutting tools 16 on the pull plate 14 are installed and replaced, and then moved to the location of the part for cutting. At the same time, the opening and closing plate 13 closes to keep the debris splashed during the cutting process away from the pull plate 14. During normal operation of the vertical five-axis machining center 1, as the types of parts change and the processing requirements vary, different types of cutting tools 16 need to be replaced. At this time, the spindle 15 can be moved to one side of the position of the cutting tool 16 under the movement of the driver 11. The opening of the first slide 2 and the corresponding insertion of the positioning block 21 are achieved. Through the squeezing effect provided by the electric push rod 25, the clamping plate 24 is inserted into the second slide 22 to complete the cutting. After the machining tool 16 is fixed and the installation steps between the machining tool 16 and the positioning block 21 are completed, during the cutting process, as the rotational speed increases, the limiting post 32 will move to both sides of the limiting rod 31 under the action of centrifugal force. At this time, the limiting post 32 will enter the corresponding groove inside the first slide groove 2, maintaining the connection between the spindle 15 and the positioning block 21. At the same time, during the movement of the limiting post 32, the anti-detachment block 34 will contact the rubber pad 33, pushing the rubber pad 33, so that the rubber pad 33 and the first slide groove 2 are aligned. The groove is fitted. During normal use of the vertical five-axis machining center 1, when dealing with different types of parts, it is necessary to change the machining tool 16. At this time, during the cutting process, some metal impurities are attached to some side walls of the replaced machining tool 16. After the machining tool 16 is placed inside the positioning ring 4, the fan 44 installed inside the fifth slide 43 operates normally and generates an upward airflow. The airflow is kept in communication with the positioning ring 4 through the fourth slide 41. The surface of the machining tool 16 is cleaned by the blowing effect of the airflow.

[0058] During the insertion of different types of machining tools 16 into the positioning ring 4, as the bottom of the extrusion column 54 gradually contacts multiple sets of push blocks 5, the downward extrusion force generated by the extrusion column 54 can drive the push blocks 5 to move outward from the positioning ring 4 by utilizing the tilt angle generated by the side wall of the push blocks 5. This causes the braided belt 53 to contract, pulling the side plate 51 outward and creating a gap. Under the blowing of the subsequent rising airflow, the gap created by the unfolding of the side plate 51 increases the airflow channel, facilitating the discharge of impurities cut from the side wall of the machining tool 16 from inside the positioning ring 4. During the opening and closing movement of the opening and closing plate 13, as the opening and closing plate 13 moves, it will be carried by the first rack 6. When the linkage rod 61 rotates, the meshing connection between the linkage rod 61 and the second rack 62 can drive the second rack 62 to produce a displacement effect, causing the opening and closing plate 13 to push the shield plate 63 to the position of the fifth slide 43 in the open and closed state, covering the top of the fifth slide 43 and blocking the upward airflow generated by the fan 44. As the opening and closing plate 13 drives the second rack 62 to move, the shield plate 63 will drive multiple sets of impact plates 71 to contact the end of the positioning plate 7 sidewall. Through the multiple sets of sixth slide 72 opened on the sidewall of the multiple positioning plates 7, the impact plate 71 will continuously contact the sixth slide 72 during the movement of the impact plate 71, causing it to jerk.

[0059] During the opening and closing of the opening and closing plate 13, as the second rack 62 moves, it drives the baffle plate 63 to move as a whole. At this time, the support rod 82 installed on the side wall of the baffle plate 63 can drive the slider 81 to move inside the seventh slide groove 8. Through the overall restraining effect of the positioning plate 7 and the seventh slide groove 8, the stability of the baffle plate 63 during movement is maintained. During the process of storing the machining tool 16 inside the positioning ring 4, as the opening and closing plate 13 closes, the baffle plate 63 is retracted and exposed in the fifth slide groove 43, allowing the upward movement to proceed. The blowing wind causes the air belt 9 to sway inside the positioning ring 4, beating the metal impurities cut off by the machining tool 16 and allowing the impurities to be discharged smoothly. During the placement of different types of machining tools 16, the No. 8 slide groove 101 opened on the top of the positioning ring 4 can guide the machining tool 16 to smoothly enter the positioning ring 4 for placement by its own tilt angle. At the same time, the tilt angle of the No. 8 slide groove 101 can correspond to the tilt angle of the push block 5, so that the machining tool 16 is centered during the insertion process.
