DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, as Figures 1-6 shown, a quick connection structure for a barrel cutter of a hole punching machine includes a connection disk 12 and a barrel cutter body 28. A main shaft 11 is installed at the middle position of the upper end of the connection disk 12. A plurality of spring cavities 13 are formed inside the connection disk 12. A plurality of moving cavities 14 are formed at the lower end of the connection disk 12. Each spring cavity 13 communicates with the corresponding moving cavity 14 inside. A plurality of fixing cavities 30 are formed at the upper end of the barrel cutter body 28. Each moving cavity 14 corresponds to a fixing cavity 30. Fixing components are arranged inside the spring cavities 13, moving cavities 14, and fixing cavities 30 for connecting the connection disk 12 and the barrel cutter body 28.
[0027] In this embodiment, first, the connection disk 12 and the barrel cutter body 28 are connected by using a fixing structure, and finally, the main shaft 11 is installed at the upper end of the connection disk 12.
[0028] In one embodiment, as Figure 2 and Figure 6 shown, the fixing components include a sliding rod 15. The sliding rod 15 is slidably installed inside the spring cavities 13 and moving cavities 14. The lower end of the spring cavity 13 extends into the fixing cavity 30 and is fixedly connected to a fixing cone 19. A limiting member 18 is fixedly installed on the outer sidewall of the sliding rod 15. The outer wall of the limiting member 18 is slidably connected to the inner wall of the moving cavity 14. A moving cone 20 is slidably connected to the outer sidewall of the sliding rod 15. The moving cone 20 is located below the limiting member 18. A pressing unit is arranged inside the spring cavity 13. A locking unit is arranged inside the fixing cavity 30. The upper end of the sliding rod 15 extends to the upper end of the connection disk 12 and is fixedly connected to a fixing plate 21. An anti-pressing unit is installed at the upper end of the connection disk 12.
[0029] When the connection disk 12 and the barrel cutter body 28 are connected, by pressing down the sliding rod 15, the sliding rod 15 slides inside the spring cavities 13 and moving cavities 14, thereby pressing down the pressing unit. The fixing cone 19 enters the fixing cavity 30, and the locking unit fixes the fixing cone 19 inside the fixing cavity 30, thereby connecting the connection disk 12 and the barrel cutter body 28. Subsequently, the fixing plate 21 is rotated into the anti-pressing unit. When the connection disk 12 and the barrel cutter body 28 are disassembled, the sliding rod 15 is pressed down again. The sliding rod 15 slides inside the spring cavities 13 and moving cavities 14. The limiting member 18 restricts the sliding of the moving cone 20 on the outer sidewall of the sliding rod 15. The moving cone 20 enters the fixing cavity 30. The sliding rod 15 is released, and the sliding rod 15 resets under the elastic return of the pressing unit. The fixing cone 19 and the moving cone 20 are disengaged from the locking unit, thereby realizing disassembly. The disassembly and assembly are convenient, which is beneficial for the staff to operate and improves work efficiency.
[0030] In one embodiment, as Figure 2 and Figure 6As shown, the pressing unit includes a main spring 17. The main spring 17 is installed inside a spring cavity 13. The middle position of the main spring 17 passes through a sliding rod 15. A fixing member 16 is fixedly installed on the outer wall of the sliding rod 15. The outer wall of the fixing member 16 is slidably connected to the inner wall of the spring cavity 13. The upper end of the main spring 17 is fixedly connected to the fixing member 16, and the lower end of the main spring 17 is fixedly connected to the inner wall of the spring cavity 13.
[0031] When the connecting disk 12 is connected to the cylinder cutter body 28, the sliding rod 15 slides downward inside the spring cavity 13 and the movable cavity 14. The fixing member 16 presses down the main spring 17, and the main spring 17 contracts. When the connecting disk 12 is disassembled from the cylinder cutter body 28, under the elastic force of the main spring 17, the sliding rod 15 and the fixing member 16 are reset, so that the fixing cone 19 is separated from the inside of the fixing cavity 30, thereby realizing disassembly, facilitating the operation of the staff and improving work efficiency.
[0032] In one embodiment, as Figure 2 and Figure 6 shown, the locking unit includes side spring cavities 32. The side spring cavities 32 are opened on both sides of the fixing cavity 30. A side movable cavity 31 is opened at one end of the side spring cavity 32 away from the fixing cavity 30. The inside of the fixing cavity 30, the side movable cavity 31, and the side spring cavities 32 are connected and communicated. A side rod 33 is slidably installed inside the side movable cavity 31 and the side spring cavities 32. One end of the side rod 33 extends into the side movable cavity 31 and is fixedly installed with a side limit block 35. The side limit block 35 is slidably installed inside the side movable cavity 31. The other end of the side rod 33 is fixedly connected to a triangular block 36. A rebounding member is installed inside the side spring cavity 32.
[0033] When the fixing cone 19 enters the inside of the fixing cavity 30, the fixing cone 19 presses the triangular blocks 36 on both sides. The triangular blocks 36 enter the side spring cavity 32, the rebounding member contracts, and the side limit block 35 slides inside the side movable cavity 31. When the fixing cone 19 completely enters the inside of the fixing cavity 30, the rebounding member rebounds, the triangular blocks 36 are reset, and the two triangular blocks 36 are located above the fixing cone 19, thereby restricting the fixing cone 19 inside the fixing cavity 30, and thus realizing the rapid installation of the connecting disk 12 and the cylinder cutter body 28. When the connecting disk 12 is disassembled from the cylinder cutter body 28, the movable cone 20 enters the inside of the fixing cavity 30, and the rebounding member is pressed again. Since the side wall of the side spring cavity 32 is a conical surface, under the mutual cooperation of the main spring 17 and the rebounding member, the fixing cone 19 and the movable cone 20 are separated from the fixing cavity 30, thereby realizing disassembly, facilitating the operation of the staff and improving work efficiency.
[0034] In one embodiment, as Figure 1 and Figure 3As shown, the anti-pressure unit includes a first limiting member 22 and a second limiting member 24. The first limiting member 22 and the second limiting member 24 are fixedly installed at the upper end of the connecting disk 12. The first limiting member 22 and the second limiting member 24 are symmetrically fixed on both sides of the fixed plate 21. A second limiting groove 25 matching the fixed plate 21 is formed on one side of the second limiting member 24, and a first limiting groove 23 matching the fixed plate 21 is formed on the other side of the first limiting member 22.
[0035] After the connecting disk 12 is installed and connected to the cylinder cutter body 28, by rotating the sliding rod 15, the fixed plate 21 is driven to rotate. One end of the fixed plate 21 enters the inside of the first limiting groove 23, and the other end of the fixed plate 21 enters the inside of the second limiting groove 25, thereby preventing the sliding rod 15 from being pressed down and moving, so that the connecting disk 12 and the cylinder cutter body 28 are separated from each other, thus ensuring the stability of the connection between the connecting disk 12 and the cylinder cutter body 28.
[0036] In one embodiment, as Figure 2 and Figure 6 shown, the rebounding member includes a side spring 34. One end of the side spring 34 is fixedly connected to the inner wall of the side spring cavity 32, and the other end of the side spring 34 is fixedly connected to the triangular block 36.
[0037] Since the side wall of the side spring cavity 32 is a conical surface, under the mutual cooperation of the main spring 17 and the side spring 34, the fixed cone 19 and the movable cone 20 are separated from the fixed cavity 30, thereby realizing disassembly, facilitating the operation of the staff, and improving work efficiency.
[0038] In one embodiment, as Figure 4 and Figure 5 shown, a positioning groove 26 is formed at the lower end of the connecting disk 12, and a positioning ring 29 matching the positioning groove 26 is fixedly installed at the upper end of the cylinder cutter body 28.
[0039] Through the cooperation of the positioning ring 29 and the positioning groove 26, the connecting disk 12 and the cylinder cutter body 28 are closely attached, thereby facilitating the installation and disassembly of the connecting disk 12 and the cylinder cutter body 28.
[0040] In one embodiment, as Figure 4 and Figure 5 shown, a groove 37 is formed at the middle position of the upper end of the cylinder cutter body 28, and a convex block 27 matching the groove 37 is fixedly installed at the middle position of the lower end of the connecting disk 12.
[0041] Through the cooperation of the groove 37 and the convex block 27, the movable cavity 14 at the lower end of the connecting disk 12 corresponds to the fixed cavity 30 at the upper end of the cylinder cutter body 28, thereby ensuring the subsequent connection and installation of the connecting disk 12 and the cylinder cutter body 28.
[0042] The above embodiments disclose a quick connection structure for a barrel cutter used in a hole punching machine. Among them, when the connection disk 12 is connected to the barrel cutter body 28, by pressing down the sliding rod 15, the sliding rod 15 slides inside the spring cavity 13 and the movable cavity 14, the fixing member 16 presses down the main spring 17, the main spring 17 contracts, when the fixing cone 19 enters the inside of the fixing cavity 30, the fixing cone 19 squeezes the triangular blocks 36 on both sides, the triangular blocks 36 enter the inside of the side spring cavity 32, the side spring 34 contracts, the side limit block 35 slides inside the side movable cavity 31, when the fixing cone 19 completely enters the inside of the fixing cavity 30, the side spring 34 rebounds, the triangular blocks 36 reset, the two triangular blocks 36 are located at the upper end of the fixing cone 19, thereby restricting the fixing cone 19 inside the fixing cavity 30, and further realizing the quick installation of the connection disk 12 and the barrel cutter body 28; when the connection disk 12 and the barrel cutter body 28 are disassembled, the movable cone 20 enters the inside of the fixing cavity 30, the side spring 34 is squeezed again, because the side wall of the side spring cavity 32 is a conical surface, under the mutual cooperation of the main spring 17 and the side spring 34, the fixing cone 19 and the movable cone 20 are separated from the fixing cavity 30, and further realizing the disassembly.
[0043] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
