Description

Technical Field

[0001] This invention relates to the field of automated machining technology, and in particular to an automatic tool changer, a tool magazine scheduling system, and a polishing machine tool. Background Technology

[0002] In modern industrial production, polishing machines are widely used in machinery manufacturing, electronic components, precision instruments, and other fields to grind and polish workpiece surfaces to achieve high-precision, high-quality surface finishes. The grinding rod, as one of the core components of the polishing machine, directly affects the polishing effect and processing efficiency. However, in actual production, after repeated use, the grinding rod's grinding performance gradually declines due to wear, material fatigue, and other factors, eventually leading to failure. When the grinding rod fails, not only will the polishing quality of the workpiece surface fail to meet expectations, resulting in increased surface roughness and poor flatness, but it will also significantly reduce the polishing machine's efficiency, increasing production time and costs.

[0003] Currently, the main method for dealing with failed polishing rods is to directly replace them with new ones. For example, Chinese Patent CN219485303U discloses a multi-station polishing machine with replaceable consumables, which includes: a frame, a Y-axis motion module mounted on the frame, an X-axis motion module mounted on the Y-axis motion module, a C-axis module mounted on the X-axis motion module for positioning the workpiece, a Z-axis motion module vertically mounted on the frame and located next to the X-axis motion module, a spindle module mounted on the Z-axis motion module for polishing the workpiece, and a consumables library mounted on the X-axis motion module and located next to the C-axis module. The consumables library stores several polishing consumables for replacing the spindle module. The X-axis motion module, Y-axis motion module and Z-axis motion module work together to move the spindle module to the consumables library for automatic replacement of polishing consumables. This solves the problem of time-consuming and labor-intensive manual replacement of consumables and enables continuous multi-process processing, thereby improving the machine tool's uptime.

[0004] However, the consumables storage of the aforementioned polishing machine is integrated inside the polishing machine. When replacing the polishing consumables in the storage, the machine must be stopped, which reduces the production efficiency of the polishing machine. Summary of the Invention

[0037] Example 1:

[0038] This invention provides an automatic tool changer, such as... Figures 1-6 As shown, it includes: an automatic tool magazine consumable tray mechanism, which includes a mounting frame 1, a tool magazine ejector frame 2 slidably mounted on the mounting frame 1, a consumable tray assembly and several consumable tray bodies 6 at the bottom of the tool magazine ejector frame 2, the consumable tray bodies 6 being detachably connected to the consumable tray assembly, the consumable tray assembly including a tool changing panel 3, the tool changing panel 3 being connected to the bottom of the tool magazine ejector frame 2, a tool changing base plate 4 being mounted below the tool changing panel 3, the tool changing base plate 4 being connected to the tool changing panel 3 through several connecting components, several hanging plates 5 being mounted on the lower surface of the tool changing base plate 4, a consumable tray body 6 being slidably mounted between two adjacent hanging plates 5, several mounting holes 7 being provided inside the consumable tray body 6, and a consumable body 8 being mounted inside the mounting holes 7.

[0039] The working principle and beneficial effects of the above technical solution are as follows: The mounting frame 1 is fixedly installed inside the machine tool body 20. A tool magazine ejector 2 is slidably installed inside the mounting frame 1, capable of sliding left and right within the mounting frame 1. A consumable tray assembly is installed at the bottom of the tool magazine ejector 2. The consumable tray assembly includes a tool changer panel 3 and a tool changer base plate 4. The tool changer base plate 4 is connected to the tool changer panel 3 via a connecting assembly, allowing it to slide back and forth below the tool changer panel 3. Multiple hanging plates 5 are installed on the lower surface of the tool changer base plate 4. A consumable tray body 6 is installed between adjacent hanging plates 5. Multiple mounting holes 7 are provided inside the consumable tray body 6, arranged in a rectangular array. A consumable body 8 is installed in each mounting hole 7, and the consumable body 8 is detachably connected to the mounting hole 7. For the disassembly and assembly of the consumable body 8, preferably, the consumable tray body 6 is provided with six sets. When all the consumable bodies 8 in the consumable tray body 6 need to be replaced, the tool magazine ejector 2 is pushed to the left side, which can remove the failed consumable bodies 8 in the three sets of consumable tray bodies 6 on the left side and install new consumable bodies 8, thus realizing the replacement of the consumable bodies 8 in the three sets of consumable tray bodies 6 on the left side. Pushing the tool magazine ejector 2 to the right side can replace the consumable bodies 8 in the three sets of consumable tray bodies 6 on the right side, thereby realizing the overall replacement of the consumable bodies 8. The tool magazine ejector 2 can drive the consumable tray assembly to slide to the outside of the machine tool body 20, so that the consumable bodies 8 can be replaced without stopping the machine, effectively shortening the waiting time, ensuring the continuity of polishing machine production, and improving production efficiency.

[0040] Example 2:

[0041] Based on the above embodiment 1, as follows Figure 2 As shown, several connecting components are distributed at equal intervals along the length of the tool changer base plate 4;

[0042] The connecting component includes a slide rail 9, which is disposed on the lower surface of the tool changing panel 3. Several first sliders 10 are slidably disposed at the bottom of the slide rail 9, and the lower surface of the first sliders 10 is connected to the upper surface of the tool changing base plate 4.

[0043] The working principle and beneficial effects of the above technical solution are as follows: pushing the tool changer base plate 4 forward can make the tool changer base plate 4 slide forward, the first slider 10 slides forward on the slide rail 9, and the tool changer base plate 4 drives the consumable tray body 6 to move forward through the hanging plate 5, thereby facilitating the adjustment of the position of the consumable tray body 6.

[0044] Example 3:

[0045] Based on Example 1 or 2, such as Figure 3As shown, two adjacent hanging plates 5 are provided with a sliding groove 11 close to each other on one side. The left and right ends of the consumable tray body 6 are respectively slidably connected to the inner wall of the sliding groove 11. Handles are provided at the front and rear ends of the consumable tray body 6. Several limiting grooves 12 are provided on the front side wall of the consumable tray body 6. A limiting block 13 corresponding to the limiting groove 12 is provided on the lower surface of the tool changing base plate 4. A limiting rod 14 is provided at the lower end of the limiting block 13. The lower end of the limiting rod 14 extends into the limiting groove 12.

[0046] The working principle and beneficial effects of the above technical solution are as follows: The consumable tray body 6 is slidably connected to the two side hanging plates 5 through the sliding groove 11. A limiting block 13 is set on the front side of the consumable tray body 6. The limiting rod 14 at the lower end of the limiting block 13 can be inserted into the limiting groove 12 on the front side wall of the consumable tray body 6, thereby improving the stability of the consumable tray body 6 between the two hanging plates 5. A locking plate is set on the rear side of the hanging plate 5. The locking plate is rotatably connected to the rear side wall of the hanging plate 5 through a rotating shaft. A torsion spring is set on the rotating shaft. One end of the torsion spring is connected to the locking plate, and the other end of the torsion spring is connected to the rear side wall of the hanging plate 5. Initially, under the elastic force of the torsion spring, the locking plate is in a horizontal state and locked. Both ends of the plate can extend to the rear of the consumable tray body 6, thereby blocking the consumable tray body 6 and preventing it from sliding out of the slide groove 11. When it is necessary to replace the consumable body 8, first push the tool magazine ejector 2 to the outside of the machine tool body 20, and then rotate the locking plate to make the locking plate in a vertical state. At this time, the consumable tray body 6 can be pulled out from the rear between the two hanging plates 5, and the consumable tray body 6 can be removed as a whole. The entire tray can be used to replace the consumable body 8, so that the machine tool body 20 can store a large number of consumable bodies 8 for replacement. By replacing the entire tray of consumable bodies 6, the replacement efficiency is further improved and the time for the tool magazine ejector 2 to be pushed outward is shortened.

[0047] Example 4:

[0048] Based on any one of Examples 1-3, such as Figures 4-9 As shown, a claw 15 is provided in the mounting hole 7. The claw 15 is made of elastic material and has a ring structure. A first opening is provided on the rear side of the claw 15. The two ends of the first opening are bent away from the center of the claw 15 to form a bent part 16. A ring-shaped retaining strip 17 is provided on the inner wall of the claw 15.

[0049] The working principle and beneficial effects of the above technical solution are as follows: The consumable body 8 includes a knife handle 21, a first connecting section 22, a second connecting section 23, and a grinding rod 24 arranged sequentially. The grinding rod 24 can grind and polish the inner cavity of the glass groove. The knife handle 21 and the grinding rod 24 are connected by the first connecting section 22 and the second connecting section 23. An annular groove 25 is provided in the first connecting section 22, and the diameter of the first connecting section 22 is larger than the diameter of the second connecting section 23. A claw 15 is provided in the mounting hole 7. The front end of the claw 15 is connected to the front side wall of the mounting hole 7, and the rear end of the claw 15 is provided with... A bend 16 is provided, and the distance between the two bends 16 and the end away from the claw 15 is greater than the length of the first opening. An annular retaining strip 17 is provided on the inner wall of the claw 15. The annular retaining strip 17 is adapted to the inner wall of the annular groove 25 of the consumable body 8. When installing the consumable body 8, first insert the grinding rod 24 of the consumable body 8 upward into the mounting hole 7, with the grinding rod 24 located at the rear of the mounting hole 7. Then, align the annular groove 25 of the first connecting section 22 with the annular retaining strip 17, and push the consumable body 8 closer to the inside of the claw 15. The annular groove 25 of the consumable body 8 is first away from the bend 16. When the inner wall of one end of the claw 15 contacts the consumable body 8, as the distance between the two bent portions 16 gradually decreases, the consumable body 8 can gradually push the two bent portions 16 to the left and right sides through the annular groove 25 when pushed towards the claw 15. After the annular groove 25 passes through the connection between the bent portion 16 and the claw 15, the consumable body 8 can be quickly pushed into the claw 15, and the annular locking strip 17 is inserted into the annular groove 25, thereby fixing the consumable body 8 in the claw 15, realizing the installation of the consumable body 8; when removing the consumable body 8, push the consumable body 8 backward. The consumable body 8 is opened by the annular groove 25 at the connection between the bent part 16 and the claw 15, and then enters the rear position of the mounting hole 7 after passing through the bent part 16. At this time, the consumable body 8 is separated from the claw 15. The consumable can be taken out from the mounting hole 7 by pulling down. In the above scheme, the consumable body 8 can be firmly locked in the mounting hole 7 by the claw 15, realizing the reliable installation of the consumable body 8. Moreover, the consumable body 8 is easy to disassemble and assemble, and can be quickly disassembled and assembled, which is conducive to the rapid replacement of the consumable body 8 and further improves the overall replacement efficiency of the consumable body 8.

[0050] Example 5:

[0051] Based on any one of Examples 1-4, such as Figure 1 , Figure 2 , Figure 12 As shown, a first driving mechanism is provided between the tool changing base plate 4 and the tool changing panel 3. The first driving mechanism is used to drive the tool changing base plate 4 to slide back and forth under the tool changing panel 3.

[0052] A second drive mechanism is provided on the mounting frame 1. The second drive mechanism is used to drive the tool magazine ejector 2 to slide left and right on the mounting frame 1.

[0053] Anti-collision mounting plates 18 are installed on the left and right sides of the tool magazine ejection rack 2, and anti-collision sensors 19 are installed on the anti-collision mounting plates 18.

[0054] The working principle and beneficial effects of the above technical solution are as follows: the first drive mechanism can drive the tool changer base plate 4 to slide back and forth under the tool changer panel 3, and the second drive mechanism can push the tool magazine ejector 2 to slide left and right within the mounting frame 1. Both the first drive mechanism and the second drive mechanism can be selected from servo motors and lead screw mechanisms. The servo motors and lead screw mechanisms are all based on existing technology and will not be described in detail here. Anti-collision sensors 19 are installed on both the left and right sides of the tool magazine ejector 2, which can prevent the tool magazine ejector 2 from hitting the operator when it is pushed out of the machine tool body 20, thus improving safety.

[0055] The automatic tool changer also includes a tool changing mechanism housed within the machine tool body 20. The tool changing mechanism comprises a three-axis linear module and an A-axis rotary assembly. The three-axis linear module includes an X-axis guide rail, an X-axis moving component slidably mounted on the X-axis guide rail, a Y-axis guide rail mounted on the X-axis moving component, a Y-axis moving component slidably mounted on the Y-axis guide rail, a Z-axis guide rail mounted on the Y-axis moving component, and a Z-axis moving component slidably mounted on the Z-axis guide rail. The A-axis rotary mechanism is mounted on the Z-axis moving component and includes a second servo motor, an A-axis spindle box 26, and a power supply. Axis 27, the second servo motor is mounted on the Z-axis moving part, and the output end of the second servo motor is connected to the A-axis spindle box 26 through a reducer. The A-axis spindle box 26 contains several electric spindles 27, preferably six, which are equally spaced and correspond to six consumable tray bodies 6. The output end of each electric spindle 27 is equipped with a pneumatic chuck 28, which clamps the tool holder 21 portion of the consumable tray body 8. When the consumable tray body 8 held by the pneumatic chuck 28 fails to clamp, the second servo motor rotates. The A-axis spindle box 26 is rotated, causing the grinding rod 24 of the consumable body 8 inside the pneumatic chuck 28 to face upwards. Then, the three-axis linear module is controlled to work, aligning the grinding rod 24 with the mounting hole 7 where the consumable body 8 is not installed. The Z-axis moving component moves upwards, causing the grinding rod 24 inside the pneumatic chuck 28 to insert into the mounting hole 7. Then, the Y-axis moving component moves, causing the consumable body 8 inside the pneumatic chuck 28 to move forward and engage with the jaw 15. Then, the pneumatic chuck 28 releases the tool holder 21, and the Z-axis moving component moves downwards, causing the pneumatic chuck 28 to engage with the consumable body 8. The consumable body 8 is separated, and then the first drive mechanism pushes the tool change base plate 4 to move, so that the pneumatic chuck 28 is aligned with the unused consumable body 8. The Z-axis motion component moves upward, so that the tool holder 21 is inserted into the pneumatic chuck 28. The pneumatic chuck 28 clamps the tool holder 21. Then the Y-axis motion component moves, so that the consumable body 8 in the pneumatic chuck 28 moves backward to the outside of the jaw 15. The Z-axis motion component moves downward, and the pneumatic chuck 28 takes the unused consumable body 8 out of the mounting hole 7, thereby completing the replacement of the consumable body 8 in the pneumatic chuck 28.

[0056] Example 6:

[0057] Based on Example 5, such as Figures 4-11As shown, an auxiliary installation component is installed inside the mounting hole 7. This component includes a U-shaped sliding plate 29, positioned on the side of the mounting hole 7 away from the claw 15. The outer wall of the U-shaped sliding plate 29 is slidably connected to the inner wall of the mounting hole 7. Several guide grooves 30 are provided on the inner wall of the mounting hole 7. Guide blocks 31 are slidably installed within the guide grooves 30, with one end extending outside the guide groove 30 and connecting to the outer wall of the U-shaped sliding plate 29. Two mounting plates 32 are provided between the U-shaped sliding plate 29 and the claw 15, arranged symmetrically on the left and right sides. One end of each mounting plate 32 is connected to the inner wall of the mounting hole 7. A drive plate 33 is positioned above the mounting plate 32. The end of the drive plate 33 closest to the claw 15 is rotatably connected to the mounting plate 32 via a pivot 34. A roller 35 is rotatably mounted at the front end of the drive plate 33, contacting the inner side of the bent portion 16. A fixing plate 36 is positioned behind the mounting plate 32, with one end connected to the side wall of the mounting hole 7. A sliding hole is provided within the fixing plate 36. A sliding plate 37 is installed inside the sliding hole, and the sliding plate 37 is slidably connected to the inner wall of the sliding hole. The lower end of the sliding plate 37 contacts the upper surface of the U-shaped sliding plate 29. A movable shell 38 is installed on the fixed plate 36, and the lower end of the movable shell 38 is slidably connected to the upper surface of the fixed plate 36. A second opening is provided on the lower side of the movable shell 38, and the upper end of the sliding plate 37 extends through the second opening into the movable shell 38. An inclined hole 39 is provided on the side wall of the movable shell 38, and the height of the inclined hole 39 near the inner wall of the mounting hole 7 is higher than the inclined hole 39. The height of the end of the inclined hole 39 away from the inner wall of the mounting hole 7 is such that a sliding column 40 is slidably installed inside the inclined hole 39. The sliding column 40 is perpendicular to the sliding plate 37 and is rotatably connected to the upper end of the sliding plate 37. A sleeve 41 is provided on the side of the movable shell 38 near the drive plate 33. A drive column 42 is slidably installed inside the sleeve 41. One end of the drive column 42 is connected to the inner wall of the sleeve 41 through a connecting spring 43. A ball bearing 44 is provided on the end of the drive column 42 near the drive plate 33. The ball bearing 44 contacts the side wall of the drive plate 33.

[0058] The working principle and beneficial effects of the above technical solution are as follows: When installing the consumable body 8, the grinding rod 24 of the consumable body 8 is inserted into the mounting hole 7 with the grinding rod 24 facing upward. During the insertion of the consumable body 8 from bottom to top, the inner diameter of the U-shaped sliding plate 29 is smaller than the diameter of the first connecting section 22 and larger than the diameter of the second connecting section 23. Therefore, the second connecting section 23 can pass through the U-shaped sliding plate 29, while the upper surface of the end of the first connecting section 22 near the grinding rod 24 contacts the lower surface of the U-shaped sliding plate 29. As the consumable body 8 continues to be pushed upward, the first connecting section 22 drives the U-shaped sliding plate 29 to slide upward along the inner wall of the mounting hole 7. The U-shaped sliding plate 29 drives the sliding plate 37 to slide vertically upward. The sliding post 40 at the upper end of the sliding plate 37 slides along the inclined hole 39, thereby driving the movement... The movable shell 38 slides along the upper surface of the fixed plate 36 away from the inner wall of the mounting hole 7. The two movable shells 38 slide synchronously towards each other. The movable shells 38 drive the drive column 42 to move through the connecting spring 43 in the sleeve 41. The drive column 42 pushes the drive plate 33 to rotate through the ball bearing 44. One end of the drive plate 33 with the roller 35 drives the bent part 16 to move towards the inner wall of the mounting hole 7. The ends of the two bent parts 16 move away from each other, so that the first opening gradually increases until the consumable body 8 can no longer be pushed upward. At this time, the guide block 31 contacts the top wall of the guide groove 30, and the annular groove 25 is exactly aligned with the annular locking strip 17 of the clasp 15. At the same time, because the first opening is opened to the maximum state, it then moves towards the clasp 15. The consumable body 8 is pushed horizontally. Guided by the lower surface of the U-shaped slide plate 29, the consumable body 8 smoothly enters the jaw 15. Then, the U-shaped slide plate 29 slides downward and returns to its original position. Under the elastic force of the bent part 16, the drive plate 33 returns to its original position. The jaw 15 clamps the consumable body 8 into the mounting hole 7 via the annular retaining strip 17, completing the installation of the consumable body 8. During the installation process, the upward upper limit action of the U-shaped slide plate 29 ensures that the annular groove 25 of the consumable body 8 is accurately aligned with the annular retaining strip 17 in the jaw 15, facilitating accurate installation of the consumable body 8. Furthermore, the drive plate 33 drives the roller 35 to open the bent part 16, increasing the first opening and facilitating the entry of the consumable body 8 into the jaw 15, thus reducing the number of jaws 15. The wear of the consumable body 8 and the wear of the pawl 15 extend the service life of the pawl 15. The distance from the upper end of the rotating shaft 34 to the roller 35 is less than the distance from the upper end of the rotating shaft 34 to the ball 44. Therefore, opening the bent part 16 by the roller 35 significantly reduces the force required for operation compared to directly opening the bent part 16, which has a labor-saving effect and facilitates the quick installation of the consumable body 8. The contact between the roller 35 and the inner wall of the bent part 16 can further reduce friction and extend the service life. When removing the consumable body 8, first push the U-shaped sliding plate 29 upward. When the U-shaped sliding plate 29 can no longer be pushed, the first opening is opened to the maximum state. At this time, the consumable body 8 can be slid horizontally to the outside of the pawl 15 and then taken out from the mounting hole 7, which improves the disassembly efficiency of the consumable body 8.

[0059] Example 7:

[0060] Based on Example 6, such as Figure 6 , Figure 7 As shown, a U-shaped frame 45 is provided below the mounting hole 7. A third opening is provided at the front end of the U-shaped frame 45. The distance between the left and right ends of the U-shaped frame 45 is greater than the diameter of the first connecting section 22 of the consumable body 8, and the distance between the left and right ends of the U-shaped frame 45 is less than the diameter of the end of the pneumatic chuck 28 away from the electric spindle 27. The rear end of the U-shaped frame 45 is connected to the lower surface of the U-shaped slide plate 29 through a connecting rod.

[0061] The working principle and beneficial effects of the above technical solution are as follows: When the pneumatic chuck 28 is used to clamp the consumable body 8, the pneumatic chuck 28 is first aligned with the lower end of the handle 21, and then the pneumatic chuck 28 is controlled to move upward. The pneumatic chuck 28 first contacts the U-shaped frame 45, and the U-shaped frame 45 pushes the U-shaped slide plate 29 to slide upward, so that the first opening of the jaw 15 is opened. When the first opening is opened to the maximum state, the handle 21 is completely inserted into the pneumatic chuck 28, and the pneumatic chuck 28 clamps the handle 21. Then the pneumatic chuck 28 drives the handle 21 to slide out of the jaw 15. Since the first opening is in the opened state, the consumable body 8 can easily slide backward to the outside of the jaw 15. Finally, the pneumatic chuck 28 moves downward to smoothly remove the consumable body 8, which is convenient for the use of the consumable body 8.

[0062] Example 8:

[0063] Based on Embodiment 1, a tool magazine scheduling system is also included for controlling the automatic tool changer, comprising: a controller, which is connected to a first drive mechanism, a second drive mechanism, and an anti-collision sensor 19.

[0064] The working principle and beneficial effects of the above technical solution are as follows: The controller can control the movement of the first drive mechanism, which can drive the tool changer base plate 4 to slide back and forth under the tool changer panel 3, thereby adjusting the position of the consumable tray body 6 and the consumable body 8, so as to facilitate the pneumatic chuck 28 to replace the consumable body 8. When all the consumable bodies 8 in the consumable tray body 6 need to be replaced, the controller controls the movement of the second drive mechanism, which pushes the tool magazine ejector 2 to the outside of the machine tool body 20, so that the staff can replace the consumable bodies 8 as a whole. During the pushing process, if the anti-collision sensor 19 detects that there is a staff member at one end of the tool magazine ejector 2, the controller can control the second drive mechanism to stop pushing, so as to avoid the tool magazine ejector 2 from injuring the staff member and improving the safety of the equipment.

[0065] Example 9:

[0066] Based on Example 1, such as Figure 13 , Figure 14As shown, it also includes a polishing machine tool, including the above-mentioned automatic tool changer, and a machine tool body 20. The automatic tool changer consumable tray mechanism is disposed inside the machine tool body 20, and the mounting frame 1 is connected to the inner wall of the machine tool body 20.

[0067] The working principle and beneficial effects of the above technical solution are as follows: The mounting frame 1 is fixedly installed on the machine tool body 20, thereby realizing the installation of the automatic tool changer consumable tray mechanism. The tool magazine outlet is set on the left and right sides of the machine tool body 20 respectively. The tool magazine outlet frame 2 can move to the outside of the machine tool body 20 through the outlet, which facilitates the replacement of the consumable body 8. The tool changing mechanism is set below the mounting frame 1. The tool changing mechanism includes a three-axis linear module. The Z-axis moving part of the three-axis linear module is equipped with an A-axis spindle box 26. Multiple electric spindles 27 are set in the A-axis spindle box 26. The pneumatic chuck 28 at the end of the electric spindle 27 can clamp the tool holder 21 of the consumable body 8. Then, the rotation of the electric spindle 27 can drive the grinding rod 24 to rotate, thereby realizing the polishing operation.
