Description

Technical Field

[0001] The present invention relates to the technical field of riveting machines, and particularly relates to a riveting machine for assembling aluminum pots. Background Art

[0002] The assembly of an aluminum pot refers to fixing the pot body and the pot handle. The assembly of an aluminum pot is usually carried out by a riveting machine, that is, the installation holes on the pot body and the pot handle are respectively sleeved outside the rivet, and then the riveting machine presses so that both ends of the rivet are flattened to form a fixation for the pot body and the pot handle;

[0003] When assembling an aluminum pot, usually the pot body and the pot handle are manually sleeved outside the rivet through the installation holes. Since the operator's hand cannot ensure absolute stability, the connection between the pot body and the pot handle cannot be guaranteed to be completely fitted. This leads to a possible inclination between the pot body and the pot handle, which makes the riveted joint prone to looseness after riveting, thereby reducing the riveting quality of the riveting machine. Summary of the Invention

[0004] The purpose of the present invention is to provide a riveting machine for assembling aluminum pots in order to solve the problem that the riveted joint is prone to looseness after riveting due to the incomplete fitting between the assembled components during traditional riveting.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A pressing assembly for improving the fitting degree between the pot body and the pot handle of the aluminum pot is arranged at the bottom of the hydraulic press. The pressing assembly includes a pressing head movably sleeved outside the stamping head. A first spring is sleeved outside the stamping head between the pressing head and the hydraulic press. A knocking assembly for knocking the pressing position is arranged inside the pressing head.

The driving shaft movably penetrates through the inside of the limiting groove. A first tooth groove is opened on the outer wall of the stamping head. The first gear penetrates to the outside of the pressing head and meshes with the first tooth groove.

[0010] As a further description of the above technical solution:

[0011] A feeding component is provided at the bottom of the stamping arm. The feeding component includes a cylinder fixedly connected to the bottom of the front end of the stamping arm. The telescopic end of the cylinder is fixedly connected with a push rod, and a clamping groove is formed at the front end of the push rod. A sliding groove communicating with the rivet groove is formed at the upper end of the bearing table behind the rivet groove.

[0012] As a further description of the above technical solution:

[0013] A cleaning component is provided outside the stamping head. The cleaning component includes an airbag fixedly connected between the pressing head and the hydraulic press, and a trachea is fixedly connected to the rear end of the airbag. An air blowing hole is formed at the bottom of the front end of the trachea.

[0014] As a further description of the above technical solution:

[0015] The bottom of the trachea extends below the pressing head, and the extension length of the trachea is the same as the depth of the sliding groove. The air blowing hole is formed in the extended area of the trachea. The top of the trachea is connected to the bottom of the rear end of the airbag and will not displace with the expansion and contraction of the airbag.

[0016] As a further description of the above technical solution:

[0017] A straightening component for supporting the rivet to keep it vertical is provided inside the pressing head. The straightening component includes a straightening sleeve fixedly connected to the inside of the pressing head. A trachea is fixedly connected to the rear end of the straightening sleeve, and the trachea penetrates through the pressing head and is fixedly connected to the trachea. The straightening sleeve is made of rubber material.

[0018] As a further description of the above technical solution:

[0019] A positioning component for fixing the rivet is provided inside the bearing table. The positioning component includes a rotating shaft rotatably connected to the inside of the bearing table. A positioning piece is fixedly connected to the outside of the rotating shaft. A second gear is fixedly connected to the outside of the rotating shaft above the positioning piece. A trigger component for controlling the positioning piece to implement positioning is provided in front of the positioning piece inside the bearing table.

[0020] As a further description of the above technical solution:

[0021] The trigger component includes a driving rod slidably connected between the two second gears. Second tooth grooves are formed on both sides of the driving rod. A hook is fixedly connected to the front end of the driving rod. A locking rod is slidably connected to the front end inside the bearing table, and a notch is formed in the upper part of the locking rod. The top of the locking rod penetrates and extends above the bearing table. A second spring is fixedly connected between the bottom of the locking rod and the inner bottom wall of the bearing table. A torsion spring is fixedly connected between the rotating shaft and the bearing table.

[0022] As a further description of the above technical solution:

[0023] The elastic force of the torsion spring is greater than the resistance suffered by the driving rod during displacement. The front end of the driving rod is made of an elastic material. The distance between the hook and the notch is the same as the length of the locking rod extending outside the bearing platform.

[0024] As a further description of the above technical solution:

[0025] The bottom of the stamping arm is fixedly connected to the machine body. Feeding components are arranged on both sides of the upper end of the machine body. The feeding components include vibrating feeding trays fixedly connected to both sides of the upper end of the machine body. Feeding tracks are fixedly connected to the sides of the vibrating feeding trays close to each other. A communication groove communicating with the sliding groove is formed at the top of the bearing platform. The close ends of the feeding tracks are lapped inside the communication groove.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] During stamping, the stamping head drives the pressing head to move downward synchronously. The pressing head sleeved outside the stamping head will contact the assembly area of the aluminum pot first and press the fitting area between the pot body and the pot handle around the rivet, making the fitting between the pot body and the pot handle closer. At the same time, after the pressing head contacts the assembly area, the stamping head still needs to continue to move downward. During the downward movement of the stamping head, a relative displacement occurs between the stamping head and the pressing head. Also, because the first tooth grooves on the surface of the stamping head mesh with the first gears inside the pressing head, when the stamping head moves downward, it drives the first gears to rotate. When the first gears rotate, the drive shafts at the eccentric positions at their front ends rotate synchronously. And since the drive shafts are arranged in the limiting grooves on the surface of the knocking rod, when the drive shafts rotate, they drive the knocking rod to do up-and-down reciprocating motion under the limitation of the limiting grooves, prompting the knocking rod to continuously knock the bottom of the pressing head. Through the knocking, the vibration is transmitted to the connection between the pot body and the pot handle. When the connection between the pot body and the pot handle appears in an inclined state as shown in the attached drawings, through the knocking vibration and the pressing of the pressing component, the connection between the pot body and the pot handle can be restored to be flat. This not only improves the pressing effect of the pressing component but also ensures the stamping quality of the riveting machine and reduces the loosening probability at the riveted joint after riveting.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] As Figures 1-6 shown, a riveting machine for assembling an aluminum pot provided by the present invention includes a stamping assembly 10. The stamping assembly 10 includes a stamping arm 15. A hydraulic press 11 is fixedly connected to the top of the stamping arm 15, and a stamping head 12 is fixedly connected to the telescopic tube of the hydraulic press 11. A bearing platform 13 is fixedly connected to the bottom of the front end of the stamping arm 15, and a rivet groove 14 is opened at the upper end of the bearing platform 13; a feeding assembly 30 is arranged at the bottom of the stamping arm 15. The feeding assembly 30 includes a cylinder 31 fixedly connected to the bottom of the front end of the stamping arm 15. A push rod 32 is fixedly connected to the telescopic end of the cylinder 31, and a clamping groove 33 is opened at the front end of the push rod 32. A sliding groove 34 communicating with the rivet groove 14 is opened at the upper end of the bearing platform 13 behind the rivet groove 14; a machine body 40 is fixedly connected to the bottom of the stamping arm 15. Feeding assemblies 20 are arranged on both sides of the upper end of the machine body 40. The feeding assemblies 20 include vibrating feeding trays 21 fixedly connected to both sides of the upper end of the machine body 40. Feeding tracks 22 are fixedly connected to the sides of the vibrating feeding trays 21 close to each other. A communication groove 23 communicating with the sliding groove 34 is opened at the top of the bearing platform 13. One ends of the feeding tracks 22 close to each other are lapped inside the communication groove 23;

[0047] A pressing assembly 50 for improving the fitting degree between the aluminum pot body and the pot handle is arranged at the bottom of the hydraulic press 11. The pressing assembly 50 includes a pressing head 51 movably sleeved outside the stamping head 12. A first spring 52 is sleeved outside the stamping head 12 between the pressing head 51 and the hydraulic press 11. A knocking assembly 53 for knocking the pressing place is arranged inside the pressing head 51;

[0048] The knocking assembly 53 includes a first gear 531 rotatably connected to the inside of the pressing head 51 by a shaft body. A driving shaft 532 is fixedly connected to the eccentric part at the front end of the first gear 531. A knocking rod 533 is movably connected to the inside of the pressing head 51, and a limiting groove 534 is opened on the surface of the knocking rod 533. The driving shaft 532 movably penetrates through the inside of the limiting groove 534. A first tooth groove 535 is opened on the outer wall of the stamping head 12. The first gear 531 penetrates to the outside of the pressing head 51 and meshes with the first tooth groove 535.

[0049] Specifically, first, the vibrating feeder tray 21 conveys the rivets to the inside of the chute 34 through the feeding track 22. Then, the air cylinder 31 is used to drive the push rod 32 to move forward. The push rod 32 uses the card slot 33 at its front end to be clamped outside the rivet and pushes the rivet to slide inside the chute 34 into the inside of the rivet slot 14. Then, the pot body and the pot handle to be assembled are respectively sleeved outside the rivet by using the mounting holes opened on the surface. After that, the hydraulic press 11 works to drive the stamping head 12 to stamp the rivet, so that the end of the rivet is flattened, and the assembly operation of the aluminum pot is completed;

[0050] However, when assembling the aluminum pot, usually, the pot body and the pot handle are manually sleeved outside the rivet through the mounting holes respectively. Since the operator's hand cannot ensure absolute stability, the connection between the pot body and the pot handle cannot be guaranteed to be completely fitted. This may cause the pot body and the pot handle to be inclined, which makes the riveted joint prone to looseness after riveting, thus reducing the riveting quality of the riveting machine;

[0051] Based on this, by setting the pressing component 50 and the knocking component 53, the fitting degree between the pot body and the pot handle can be improved. During stamping, the stamping head 12 will drive the pressing head 51 to move downward synchronously. The pressing head 51 sleeved outside the stamping head 12 will contact the assembly area of the aluminum pot first and press the fitting area between the pot body and the pot handle around the rivet, making the pot body and the pot handle fit more tightly. At the same time, after the pressing head 51 contacts the assembly area, the stamping head 12 still needs to continue to move downward. During the downward movement of the stamping head 12, a relative displacement occurs between the stamping head 12 and the pressing head 51. Also, because the first tooth groove 535 on the surface of the stamping head 12 meshes with the first gear 531 inside the pressing head 51, when the stamping head 12 moves downward, it drives the first gear 531 to rotate. When the first gear 531 rotates, it drives the drive shaft 532 at the eccentric part of its front end to rotate synchronously. And since the drive shaft 532 is arranged in the limit groove 534 on the surface of the knocking rod 533, when the drive shaft 532 rotates, it drives the knocking rod 533 to do reciprocating up and down movement under the restriction of the limit groove 534, prompting the knocking rod 533 to continuously knock the bottom of the pressing head 51. Through knocking, the vibration is conducted to the connection between the pot body and the pot handle, so that when the connection between the pot body and the pot handle shows an inclined state as shown in Figure 6 the figure, through knocking vibration and cooperating with the pressing of the pressing component 50, the connection between the pot body and the pot handle can be restored to be flat, which not only improves the pressing effect of the pressing component 50, but also ensures the stamping quality of the riveting machine and reduces the loosening probability of the riveted joint after riveting; After riveting, the hydraulic press 11 drives the stamping head 12 to move upward, and under the elastic reset of the first spring 52, the pressing head 51 is pushed back.

[0052] As Figure 1 、 Figure 4 and Figure 7As shown in the figure, a cleaning component 60 is provided outside the stamping head 12. The cleaning component 60 includes an airbag 61 fixedly connected between the pressing head 51 and the hydraulic press 11, and a gas guide pipe 62 is fixedly connected to the rear end of the airbag 61. An air blowing hole 63 is opened at the bottom of the front end of the gas guide pipe 62;

[0053] The bottom of the gas guide pipe 62 extends to the lower part of the pressing head 51, and the extending length of the gas guide pipe 62 is the same as the depth of the sliding groove 34. The air blowing hole 63 is opened in the extending area of the gas guide pipe 62. The top of the gas guide pipe 62 is connected to the bottom of the rear end of the airbag 61 and will not displace following the expansion and contraction of the airbag 61;

[0054] An alignment component 70 for supporting the rivet to keep it in a vertical state is provided inside the pressing head 51. The alignment component 70 includes an alignment sleeve 71 fixedly connected to the inside of the pressing head 51. A ventilation pipe 72 is fixedly connected to the rear end of the alignment sleeve 71, and the ventilation pipe 72 penetrates through the pressing head 51 and is fixedly connected and communicated with the gas guide pipe 62. The alignment sleeve 71 is made of rubber material.

[0055] Specifically, in cooperation with the characteristic that the pressing head 51 slides on the surface of the stamping head 12 during riveting and stamping, an airbag 61 is arranged between the pressing head 51 and the hydraulic press 11. Therefore, when the pressing head 51 and the stamping head 12 have a relative displacement, the airbag 61 will be squeezed, so that the gas inside the airbag 61 is discharged through the air blowing hole 63 by the gas guide pipe 62. And because the bottom of the gas guide pipe 62 extends into the inside of the sliding groove 34 and the air blowing hole 63 is also opened in the extending area of the gas guide pipe 62, the inside of the sliding groove 34 can be blown and cleaned during stamping, reducing the probability that the debris generated during stamping falls into the inside of the sliding groove 34 and causes obstruction to the rivet conveying during the riveting process, ensuring the uninterrupted riveting operation, and improving the riveting efficiency;

[0056] In addition, when the pressing head 51 moves downward, the alignment sleeve 71 inside it will wrap around the outside of the rivet to initially align the rivet. Then, in cooperation with the contraction of the airbag 61, the gas discharged from the airbag 61 will enter the inside of the alignment sleeve 71 through the ventilation pipe 72. Since the alignment sleeve 71 is made of rubber material, the alignment sleeve 71 will expand to firmly wrap the rivet, ensuring that the rivet is always in a vertical state, reducing the probability of dislocation and insecure riveting at the riveting joint due to the offset of the rivet during riveting and stamping, and improving the riveting effect and quality. Until during riveting and stamping, the stamping head 12 presses against the rivet to flatten the rivet. After that, as the stamping head 12 resets, the airbag 61 stretches and resets under the action of the first spring 52, and the gas inside the alignment sleeve 71 is pumped out.

[0057] Such as Figure 1 、 Figure 2 And Figure 8As shown in the figure, a positioning component 80 for fixing the rivet is provided inside the pressure-bearing platform 13. The positioning component 80 includes a rotating shaft 81 rotatably connected to the inside of the pressure-bearing platform 13. A positioning piece 83 is fixedly connected to the outside of the rotating shaft 81. A second gear 82 is fixedly connected to the outside of the rotating shaft 81 above the positioning piece 83. A trigger component 84 for controlling the positioning of the positioning piece 83 is provided in front of the positioning piece 83 inside the pressure-bearing platform 13;

[0058] The trigger component 84 includes a driving rod 841 slidably connected between two second gears 82. Second tooth grooves 842 are formed on both sides of the driving rod 841. A hook 843 is fixedly connected to the front end of the driving rod 841. A locking rod 844 is slidably connected to the front end inside the pressure-bearing platform 13. A notch 845 is formed in the upper part of the locking rod 844. The top of the locking rod 844 penetrates and extends above the pressure-bearing platform 13. A second spring 846 is fixedly connected between the bottom of the locking rod 844 and the inner bottom wall of the pressure-bearing platform 13. A torsion spring 847 is fixedly connected between the rotating shaft 81 and the pressure-bearing platform 13;

[0059] The elastic force of the torsion spring 847 is greater than the resistance suffered by the driving rod 841 during displacement. The front end of the driving rod 841 is made of an elastic material. The distance between the hook 843 and the notch 845 is the same as the length of the locking rod 844 extending outside the pressure-bearing platform 13.

[0060] Specifically, since the rivet is integrally composed of a rivet head at the bottom and a rivet rod at the upper part, during the process of pushing the rivet into the rivet groove 14, the card slot 33 at the front end of the push rod 32 will be stuck outside the rivet rod, so that a part of the push rod 32 will press on the rivet head. Therefore, the rivet will remain vertical during feeding. After the pot body and the pot handle are sleeved on the rivet, in order not to affect the riveting stamping, the push rod 32 will retract. At this time, the rivet is not fixed. If the hand of the assembler shakes, the rivet may shift, thus affecting the riveting quality;

[0061] Based on this, by setting the positioning component 80, the rivet is released from fixation only at the moment of stamping, ensuring that the rivet is always in a vertical state. First, when the push rod 32 pushes the rivet into the interior of the rivet groove 14, the rivet contacts the driving rod 841 and pushes the driving rod 841 forward. When the driving rod 841 moves forward, the second tooth grooves 842 on both sides thereof engage with the second gear 82 to drive the second gear 82 to rotate. The rotation of the second gear 82 drives the rotation shaft 81 to rotate, thereby driving the positioning piece 83 to rotate, causing the two positioning pieces 83 to move closer to the rivet and finally move above the rivet head of the rivet to press the rivet head, achieving the fixation of the rivet. And after the rivet enters the interior of the rivet groove 14, the hook 843 at the front end of the driving rod 841 is also pushed to the front of the locking rod 844 to hook the locking rod 844, thereby achieving the locking of the driving rod 841. It should be noted that the front end of the driving rod 841 is made of an elastic material such as but not limited to rubber, and in cooperation with the inclined surface of the hook 843, the hook 843 can deform and cross over the locking rod 844 and lock after touching the locking rod 844. Until stamping, after the pressing head 51 contacts the upper end of the locking rod 844 and pushes the locking rod 844 downward, the notch 845 of the locking rod 844 moves to the position of the hook 843, releasing the locking of the hook 843, and under the action of the elastic reset of the torsion spring 847, the rotation shaft 81 is driven to rotate back, thereby driving the second gear 82 to rotate back and driving the positioning piece 83 to rotate back to release the fixation of the rivet. At the same time, the driving rod 841 is also reset under the action of the rotation of the second gear 82, so that the rivet can be firmly fixed until the moment of riveting and stamping, reducing the probability of riveting misalignment and riveting looseness caused by rivet offset, and further ensuring the riveting quality.

[0062] Working principle: First, the vibrating feeder tray 21 conveys the rivets to the inside of the chute 34 through the feeding track 22. Then, the air cylinder 31 is used to drive the push rod 32 to move forward. The push rod 32 uses the clamping groove 33 at its front end to clamp outside the rivet and push the rivet to slide inside the chute 34 into the inside of the rivet groove 14. Next, the pot body and the pot handle to be assembled are respectively sleeved outside the rivet by using the mounting holes opened on their surfaces. After that, the hydraulic press 11 works to drive the stamping head 12 to stamp the rivet. During stamping, the stamping head 12 will drive the pressing head 51 to move downward synchronously. The pressing head 51 sleeved outside the stamping head 12 will contact the assembly area of the aluminum pot first and press the fitting area between the pot body and the pot handle around the rivet, making the pot body and the pot handle fit more tightly. At the same time, after the pressing head 51 contacts the assembly area, the stamping head 12 still needs to continue to move downward. During the downward movement of the stamping head 12, a relative displacement occurs between the stamping head 12 and the pressing head 51. Also, because the first tooth groove 535 on the surface of the stamping head 12 meshes with the first gear 531 inside the pressing head 51, when the stamping head 12 moves downward, it drives the first gear 531 to rotate. When the first gear 531 rotates, it drives the drive shaft 532 at the eccentric part of its front end to rotate synchronously. And since the drive shaft 532 is arranged in the limit groove 534 on the surface of the knocking rod 533, when the drive shaft 532 rotates, it drives the knocking rod 533 to do reciprocating up and down movements under the restriction of the limit groove 534, prompting the knocking rod 533 to continuously knock the bottom of the pressing head 51. Through the knocking, the vibration is transmitted to the connection part between the pot body and the pot handle, so that when the connection part between the pot body and the pot handle shows an inclined state as shown in Figure 6 the figure, through the knocking vibration and the pressing of the pressing assembly 50, the connection part between the pot body and the pot handle can be restored to be flat, which not only improves the pressing effect of the pressing assembly 50, but also ensures the stamping quality of the riveting machine, reduces the loosening probability of the riveting part after riveting. Finally, the end of the rivet is flattened, and the assembly operation of the aluminum pot is completed.
