[0002] In modern industrial production, polishing machines are widely used in many fields such as mechanical manufacturing, electronic devices, and precision instruments to grind and polish the surface of workpieces to obtain high-precision, high-quality surface finish. Among them, the grinding rod is one of the core components of the polishing machine, and its performance directly affects the polishing effect and processing efficiency. However, in the actual production process, after repeated use, the grinding performance of the grinding rod will gradually decline due to factors such as wear and material fatigue until it fails. When the grinding rod fails, not only will the polishing quality of the workpiece surface fail to meet the expected standards, resulting in problems such as increased surface roughness and deterioration of flatness, but it will also significantly reduce the working efficiency of the polishing machine and increase production time and costs.

Since the distance between the two bent portions 16 gradually decreases, when the consumable body 8 is pushed toward the claw 15, the consumable body 8 can gradually push the two bent portions 16 to the left and right sides through the annular groove 25. When 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 clip 17 is stuck in the annular groove 25, so that the consumable body 8 is fixed in the claw 15, and the installation of the consumable body 8 is realized. When removing the consumable body 8, push the consumable body 8 backward. The consumable body 8 opens the connection between the bent portion 16 and the claw 15 through the annular groove 25, and then passes through the bent portion 16 and enters the rear position of the mounting hole 7. At this time, the consumable body 8 is separated from the claw 15, and the consumable can be taken out of the mounting hole 7 by pulling the consumable downward. In the above scheme, the consumable body 8 can be firmly locked in the mounting hole 7 through the claw 15, thereby realizing the reliable installation of the consumable body 8, and 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.

During the upward pushing process, the first connecting section 22 drives the U-shaped slide 29 to slide upward along the inner wall of the mounting hole 7, and the U-shaped slide 29 drives the sliding plate 37 to slide vertically upward. The sliding column 40 at the upper end of the sliding plate 37 slides along the inclined hole 39, thereby driving the moving The movable shell 38 slides along the upper surface of the fixed plate 36 in the direction away from the inner wall of the mounting hole 7, and the two movable shells 38 slide synchronously in the direction of approaching each other. The movable shell 38 drives the connecting spring 43 in the sleeve 41 to drive the driving column 42 to move, and the driving column 42 pushes the driving plate 33 to rotate through the ball 44. One end of the roller 35 provided on the driving plate 33 drives the bending portion 16 to move toward the inner wall of the mounting hole 7. The ends of the two bending portions 16 move in the direction 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 aligned with the annular clip 17 of the claw 15. At the same time, since the first opening is stretched to the maximum state, it moves toward the claw 15. The consumable body 8 is pushed horizontally in the direction. Under the guidance of the lower surface of the U-shaped slide 29, the consumable body 8 enters the claw 15 smoothly, and then the U-shaped slide 29 slides downward and returns to its original position. Under the elastic force of the bent portion 16, the driving plate 33 returns to its original position, and the claw 15 clamps the consumable body 8 in the mounting hole 7 through the annular clamping strip 17 to complete the installation of the consumable body 8. During the installation process, the upward limiting action of the U-shaped slide 29 can make the annular groove 25 of the consumable body 8 accurately align with the annular clamping strip 17 in the claw 15, which is convenient for the accurate installation of the consumable body 8. In addition, the driving plate 33 drives the roller 35 to open the bent portion 16, so that the first opening is enlarged, which is convenient for the consumable body 8 to enter the claw 15, reducing the clamping claw 1 5 and the wear of the consumable body 8, thereby extending the service life of the claw 15. The distance from the upper end of the rotating shaft 34 to the roller 35 is smaller than the distance from the upper end of the rotating shaft 34 to the ball 44. Therefore, compared with directly opening the bent portion 16, opening the bent portion 16 by the roller 35 significantly reduces the force required for the operation, has a labor-saving effect, and is convenient for the rapid installation of the consumable body 8. The contact between the roller 35 and the inner wall of the bent portion 16 can further reduce friction and extend the service life. When removing the consumable body 8, first push the U-shaped slide plate 29 upward. When the U-shaped slide plate 29 cannot be pushed, the first opening is opened to the maximum state. At this time, the consumable body 8 can be horizontally slid to the outside of the claw 15 and then taken out from the mounting hole 7, thereby improving the disassembly efficiency of the consumable body 8.

[0059] Example 7:

[0060] On the basis of Example 6, 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, and the rear end of the U-shaped frame 45 is connected to the lower surface of the U-shaped slide 29 through a connecting rod.

[0061] The working principle and beneficial effects of the above technical solution are as follows: when clamping the consumable body 8 through the pneumatic chuck 28, first align the pneumatic chuck 28 with the lower end of the tool handle 21, and then control the pneumatic chuck 28 to move upward. The pneumatic chuck 28 first contacts the U-shaped frame 45, and pushes the U-shaped slide 29 to slide upward through the U-shaped frame 45, so that the first opening of the claw 15 is opened. When the first opening is opened to the maximum state, the tool handle 21 completely enters the pneumatic chuck 28, and the pneumatic chuck 28 clamps the tool handle 21. Then the pneumatic chuck 28 drives the tool handle 21 to slide toward the outside of the claw 15. Since the first opening is in the opened state, the consumable body 8 can easily slide backward to the outside of the claw 15. Finally, the pneumatic chuck 28 moves downward to smoothly take out the consumable body 8, making it convenient to take out the consumable body 8.

[0062] Example 8:

[0063] On the basis of embodiment 1, a tool magazine scheduling system is also included for controlling the automatic tool changing device, including: a controller, which is connected to the first drive mechanism, the second drive mechanism, and the 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, and the first drive mechanism can drive the tool changing base plate 4 to slide back and forth under the tool changing 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, and the second drive mechanism pushes the tool magazine output rack 2 to the outside of the machine tool body 20, and then facilitates the staff to replace the consumable body 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 output rack 2, the controller can control the second drive mechanism to stop pushing, so as to avoid the tool magazine output rack 2 from injuring the staff member, thereby improving the safety of the equipment.
