Description

TECHNICAL FIELD

[0001] The present application relates to a riveting machine, in particular to a handle mounting and riveting device for a pot. BACKGROUND

[0002] The conventional method for connecting a pot accessory with a pot body includes direct spot welding or rivet riveting. If both the pot accessory and the pot body are made of steel, they are fixed by direct spot welding, which is simple in processing technology. However, when the pot body is relatively thin, if the current impact of the spot welding machine is too large, the pot body is easily burned out. If the spot welding time and current size do not meet the process requirements, there will be a virtual welding phenomenon. If the material of the pot accessory is non-steel (such as aluminum, plastic, etc.), it can be rivet riveted with the steel pot body. If the material of the pot accessory is non-aluminum (such as steel, plastic, etc.), it can also be rivet riveted with the aluminum pot body.

[0003] Further, when installing the handle of the existing pot, a hole is first punched in the pot, then the mounting seat with the riveting hole is attached to the outer wall of the pot, and corresponds to the hole position of the pot, and then the rivet is passed through the pot and the mounting seat to realize riveting and fixing, and finally the handle is connected to the mounting seat. However, the existing riveting work mainly relies on manual operation combined with a riveting machine, which is semi-automatic, time-consuming and laborious, and has low work efficiency. SUMMARY

[0004] The purpose of the present application is to overcome the above-mentioned problems, and to provide a handle mounting and riveting device for a pot, which can automatically complete the riveting work of the mounting seat of the handle, save time and effort, and has high work efficiency.

[0005] The purpose of the present application is achieved by the following technical solutions:

[0006] A handle mounting and riveting device for a pot, comprising an inner side riveting mechanism for performing riveting work on the inner side of the pot and an outer side riveting mechanism for performing riveting work on the outer side of the pot;

[0007] The inner side riveting mechanism comprises a first feeding mechanism for automatically feeding the rivet and a first pushing riveting mechanism for pushing the rivet through the riveting hole of the pot and realizing riveting; the first pushing riveting mechanism comprises a first pushing riveting seat and a first pushing riveting driving mechanism, and the first pushing riveting seat is provided with a first riveting top rod for abutting against the head of the rivet;

[0008] The outer riveting mechanism comprises a second feeding mechanism for automatically feeding the mounting seat and a second pushing and riveting mechanism for pushing the mounting seat to the outer wall of the pot and realizing riveting; the second pushing and riveting mechanism comprises a pushing mechanism for pushing the mounting seat and a top riveting mechanism for stamping the rivet; the pushing mechanism comprises a pushing seat and a pushing driving mechanism, and the pushing seat is provided with a pushing slot for placing the mounting seat; the top riveting mechanism comprises a top riveting seat and a top riveting driving mechanism, and the top riveting seat is provided with a second riveting top rod for being abutted against the tail of the rivet, and the end of the second riveting top rod is provided with a riveting slot.

[0009] The working principle of the pot handle mounting and riveting device is as follows:

[0010] In work, the pot is invertedly conveyed to the riveting station; the mounting seat is automatically conveyed into the pushing slot of the pushing seat through the second feeding mechanism, then the outer riveting mechanism and the inner riveting mechanism are lifted, so that the inner riveting mechanism is located in the inner cavity of the pot and the outer riveting mechanism is located on the outer side of the pot, at this time, the riveting hole of the pot is located between the first riveting top rod and the second riveting top rod; the rivet is automatically conveyed in front of the first riveting top rod through the first feeding mechanism, at this time, the head of the rivet is close to the first riveting top rod and the tail of the rivet is close to the inner wall of the pot; the first pushing and riveting seat and the first riveting top rod are driven to move towards the inner wall of the pot by the first pushing and riveting driving mechanism, the first riveting top rod drives the rivet to be close to the inner wall of the pot, so that the tail of the rivet passes through the riveting hole of the pot and the rivet is pressed against the inner wall of the pot.

[0011] The pushing seat with the mounting seat is driven to be close to the pot by the pushing driving mechanism, in this process, the tail of the rivet relatively passes through the riveting hole of the mounting seat until the mounting seat is attached to the outer wall of the pot; the top riveting seat is driven to be close to the pot by the top riveting driving mechanism, so that the second riveting top rod is abutted against the tail of the rivet at high speed, the tail of the rivet is extruded and deformed, and is wrapped by the riveting slot of the second riveting top rod, so that the riveting work is completed, at this time, the rivet fixes the pot and the mounting seat together; finally, all mechanisms are reset, and the riveting work of the next pot is waited.

[0012] In one preferred scheme of the present application, the first feeding mechanism comprises a rivet vibrating disc and a pneumatic conveying assembly.

[0013] In one preferred scheme of the present application, the first pushing and riveting driving mechanism comprises a first pushing and riveting driving cylinder, the first pushing and riveting driving cylinder is fixedly arranged on the riveting rack, and the telescopic rod of the first pushing and riveting driving cylinder is fixedly connected with the first pushing and riveting seat.

[0014] In a preferred embodiment of the present invention, the inner riveting mechanism further includes a first transfer mechanism, which includes a first transfer seat. The first transfer seat has a transfer positioning hole for placing the rivet, and the upper part of the transfer positioning hole is connected to the conveying pipe of the first feeding mechanism; one end of the first riveting push rod extends into the transfer positioning hole. With the above structure, the rivet can be positioned directly in front of the riveting hole of the cookware for subsequent pushing and piercing.

[0015] Furthermore, the first transfer mechanism also includes an attitude correction component, which includes two attitude correction frames arranged vertically and a reset spring. One end of each attitude correction frame is hinged to the first transfer seat, and the other end of each attitude correction frame is located in front of the transfer positioning hole and is provided with an attitude correction groove. The two attitude correction grooves form an attitude correction hole, which includes a tapered section and a horizontal lifting section. Along the pushing direction of the rivet, the tapered section is located in the middle of the horizontal lifting section and the transfer positioning hole, and the diameter of the horizontal lifting section is smaller than the diameter of the transfer positioning hole. The two ends of the reset spring are respectively connected to the two attitude correction frames. With the above structure, due to the large size of the rivet head, when the rivet is delivered to the transfer positioning hole, its axis is inclined, not horizontal. Therefore, when the first riveting push rod pushes the rivet towards the cookware, the tail of the rivet will first contact the tapered section of the attitude correction hole, and then be guided upward by the tapered section of the attitude correction hole to the horizontal lifting section. At this time, the axis of the rivet is horizontal, so as to accurately pass through the riveting hole of the cookware, which is very ingenious. Furthermore, when the head of the rivet passes through the tapered section of the attitude correction hole, the head of the rivet will open up two attitude correction frames. The two attitude correction frames will rotate outward around their respective hinge centers (at this time, the return spring will undergo elastic deformation and store energy), avoiding the head of the rivet from approaching the cookware, until the head of the rivet is attached to the inner wall of the cookware. After the riveting is completed, the first riveting push rod returns to its original position, the return spring releases potential energy and restores its deformation, driving the two attitude correction frames to rotate and return to their original positions, ready for the next round of work.

[0016] In a preferred embodiment of the present invention, the inner riveting mechanism further includes a support mechanism for supporting the first riveting top rod. This support mechanism includes a support block and a vertical drive mechanism for driving the support block to move vertically. When the first riveting top rod presses the head of the rivet against the inner wall of the cookware, the support block is located between the first push riveting seat and the boss of the riveting frame. This structure provides stable support for the first riveting top rod, preventing it from loosening during riveting impact and ensuring smooth completion of the riveting operation.

[0017] Furthermore, the vertical support drive mechanism includes a vertical support motor and a vertical support transmission assembly, and the vertical support transmission assembly includes a vertical support lead screw and a vertical support lead screw nut.

[0018] In a preferred embodiment of the present invention, the second feeding mechanism includes a mounting base vibratory plate and a feeding pipe.

[0019] In a preferred embodiment of the present invention, the inner riveting mechanism further includes a second transfer mechanism, which includes a second transfer seat and a transverse transfer drive mechanism;

[0020] The second transfer seat is provided with a transfer slot. In the initial transfer phase, the transfer slot is located directly below the feeding pipe of the second feeder. In the subsequent transfer phase, the transfer slot is located directly above the push slot of the pusher seat.

[0021] Furthermore, the lateral transfer drive mechanism includes a lateral transfer drive cylinder, the extension rod of which is connected to the second transfer seat.

[0022] Furthermore, the inner riveting mechanism also includes a pressing mechanism, which includes a pressing block and a vertical pressing drive mechanism; the pressing is located directly above the pushing slot of the pushing seat.

[0023] Furthermore, the vertical pressing drive mechanism includes a vertical pressing drive cylinder, the extension rod of which is connected to the pressing block.

[0024] With the above structure, the transverse transfer drive cylinder first moves the transfer slot of the second transfer seat to directly below the feeding pipe of the second feeder. The feeding pipe of the second feeder then transports the mounting seat to the transfer slot of the second transfer seat. Next, the transverse transfer drive cylinder drives the second transfer seat to move laterally, pushing the mounting seat directly above the pushing slot of the pusher seat, causing the mounting seat to fall into the pushing slot below. Then, the vertical pressing drive cylinder drives the pressing block to move downward, and the pressing block fixes the mounting seat in the pushing slot to prevent it from falling off during subsequent pushing.

[0025] In a preferred embodiment of the present invention, the top riveting drive mechanism includes a top riveting drive cylinder, which is fixedly mounted on the riveting machine frame, and the telescopic rod of the top riveting drive cylinder is fixedly connected to the top riveting seat.

[0026] Furthermore, the pushing drive mechanism is composed of a top riveting drive cylinder;

[0027] An elastic pushing assembly is provided between the push seat and the top rivet seat. The elastic pushing assembly includes a push spring and a mounting guide rod. One end of the mounting guide rod is fixed to the top rivet seat, and the other end of the top rivet seat can slide through the push seat. The push spring is sleeved on the mounting guide rod, and the two ends of the push spring abut against the push seat and the top rivet seat respectively.

[0028] The pusher seat is provided with a riveting clearance hole, which is concentric with the riveting hole of the mounting seat located in the pusher slot; one end of the second riveting top rod extends into the riveting clearance hole.

[0029] With the above structure, driven by the top riveting drive cylinder, the top riveting seat pushes the push seat closer to the pot through the push spring. When the mounting seat in the push slot of the push seat is attached to the outer wall of the pot (the tail of the rivet passes through the riveting hole of the mounting seat and extends into the riveting clearance hole of the push seat), the push seat stops moving, the top riveting drive cylinder continues to drive, and the top riveting seat continues to move with the second riveting push rod (at this time, the push spring is compressed and deformed), so that the second riveting push rod hits the tail of the rivet along the riveting clearance hole of the push seat, thereby realizing riveting.

[0030] In a preferred embodiment of the present invention, a lifting drive mechanism is further included for driving the outer riveting mechanism and the inner riveting mechanism to move up and down. The lifting drive mechanism includes a lifting drive motor and a lifting transmission assembly, and the lifting transmission assembly includes a lifting screw and a lifting screw nut.

[0031] Both the outer riveting mechanism and the inner riveting mechanism are mounted on the riveting machine frame, which is fixedly connected to the lifting screw nut.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] 1. The riveting device of the present invention can automatically complete the riveting work of the handle mounting base, saving time and effort and with high work efficiency.

[0034] 2. By setting up an outer riveting mechanism and an inner riveting mechanism, the rivets can be automatically passed through the cookware and the mounting base for riveting. The operation is simple and easy to implement. Attached Figure Description

[0045] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0046] Combination Figure 1 The cookware handle mounting and riveting device of this embodiment includes an inner riveting mechanism for riveting work on the inner side of the cookware 1, an outer riveting mechanism for riveting work on the outer side of the cookware 1, and a lifting drive mechanism for driving the outer riveting mechanism and the inner riveting mechanism to move up and down.

[0047] Combination Figures 3-6 The inner riveting mechanism includes a first feeding mechanism for automatically feeding the rivets 2 and a first pushing riveting mechanism for pushing the rivets 2 through the riveting holes of the cookware 1 and achieving riveting; wherein, the first feeding mechanism includes a rivet vibrating plate and a pneumatic conveying assembly, and the specific structure can be referred to the prior art.

[0048] Combination Figures 3-6 The first push riveting mechanism includes a first push riveting seat 4 and a first push riveting drive mechanism. The first push riveting seat 4 is provided with a first riveting top rod 5 for pressing against the head of the rivet 2. The first push riveting drive mechanism includes a first push riveting drive cylinder 6, which is fixedly mounted on the riveting frame 7. The telescopic rod of the first push riveting drive cylinder 6 is fixedly connected to the first push riveting seat 4.

[0049] Combination Figures 3-6The inner riveting mechanism further includes a first transfer mechanism, which includes a first transfer seat 8. The first transfer seat 8 has a transfer positioning hole 8-1 for placing the rivet 2. The upper part of the transfer positioning hole 8-1 is connected to the conveying pipe 9 of the first feeding mechanism. One end of the first riveting top rod 5 extends into the transfer positioning hole 8-1. With the above structure, the rivet 2 can be positioned directly in front of the riveting hole of the pot 1 for subsequent pushing and drilling.

[0050] Combination Figures 3-7 The first transfer mechanism also includes an attitude correction assembly, which comprises two vertically arranged attitude correction frames 10 and a return spring 11. One end of each attitude correction frame 10 is hinged to the first transfer seat 8, and the other end of each attitude correction frame 10 is located in front of the transfer positioning hole 8-1 and is provided with an attitude correction groove. The two attitude correction grooves form an attitude correction hole 12, which includes a tapered section 12-1 and a horizontally raised section 12-2. Along the pushing direction of the rivet 2, the tapered section 12-1 is located between the horizontally raised section 12-2 and the transfer positioning hole 8-1, and the diameter of the horizontally raised section 12-2 is smaller than the diameter of the transfer positioning hole 8-1. The two ends of the return spring 11 are respectively connected to the two attitude correction frames 10. With the above structure, because the head of the rivet 2 is relatively large, when the rivet 2 is delivered to the transfer positioning hole 8-1, the axis of the rivet 2 is inclined and not horizontal. Figure 5 Therefore, when the first riveting rod 5 pushes the rivet 2 towards the pot 1, the tail of the rivet 2 will first contact the tapered section 12-1 of the attitude correction hole 12, and then be guided upward by the tapered section 12-1 of the attitude correction hole 12 to the horizontal lifting section 12-2. At this time, the axis of the rivet 2 is horizontal (or nearly horizontal), as shown below. Figure 6 This is ingeniously designed to ensure accurate passage through the riveting hole of the cookware 1. Furthermore, when the head of the rivet 2 passes through the tapered section 12-1 of the attitude correction hole 12, the head of the rivet 2 will open up the two attitude correction frames 10. The two attitude correction frames 10 will rotate outward around their respective hinge centers (at this time, the return spring 11 will undergo elastic deformation and store energy), avoiding the head of the rivet 2 from approaching the cookware 1, until the head of the rivet 2 is attached to the inner wall of the cookware 1. After the riveting is completed, the first riveting top rod 5 is reset, the return spring 11 releases potential energy to restore its deformation, and drives the two attitude correction frames 10 to rotate and reset, preparing for the next round of work.

[0051] Combination Figures 2-4The inner riveting mechanism further includes a support mechanism for supporting the first riveting top rod 5. This support mechanism includes a support block 13 and a vertical drive mechanism for driving the support block 13 to move vertically. When the first riveting top rod 5 presses the head of the rivet 2 against the inner wall of the cookware 1, the support block 13 is located between the first push riveting seat 4 and the boss of the riveting frame 7. This structure provides stable support for the first riveting top rod 5, preventing it from loosening during riveting impact and ensuring smooth completion of the riveting operation.

[0052] Furthermore, the top support vertical drive mechanism includes a top support vertical motor 14 and a top support vertical transmission assembly, the top support vertical transmission assembly including a top support vertical lead screw and a top support vertical lead screw nut.

[0054] Combination Figures 8-11 The second push riveting mechanism includes a push mechanism for pushing the mounting base 3 and a top riveting mechanism for stamping the rivet 2; the push mechanism includes a push base 15 and a push driving mechanism, the push base 15 is provided with a push slot 15-1 for placing the mounting base 3; the top riveting mechanism includes a top riveting base 16 and a top riveting driving mechanism, the top riveting base 16 is provided with a second riveting top rod 17 for pressing against the tail of the rivet 2, and the end of the second riveting top rod 17 is provided with a riveting groove.

[0055] Combination Figures 8-11 The inner riveting mechanism further includes a second transfer mechanism, which includes a second transfer seat 19 and a transverse transfer drive mechanism. The second transfer seat 19 is provided with a transfer slot 19-1. In the state of the first stage of transfer, the transfer slot 19-1 is located directly below the feeding pipe 18 of the second feeder. In the state of the second stage of transfer, the transfer slot 19-1 is located directly above the push slot 15-1 of the push seat 15.

[0056] Furthermore, the lateral transfer drive mechanism includes a lateral transfer drive cylinder 20, the extension rod of which is connected to the second transfer seat 19.

[0057] Furthermore, the inner riveting mechanism also includes a pressing mechanism, which includes a pressing block 21 and a vertical pressing drive mechanism; the pressing is located directly above the pushing slot 15-1 of the pushing seat 15.

[0058] Furthermore, the vertical pressing drive mechanism includes a vertical pressing drive cylinder 22, the telescopic rod of which is connected to the pressing block 21.

[0059] With the above structure, the transverse transfer drive cylinder 20 first drives the transfer slot 19-1 of the second transfer seat 19 to move directly below the feeding pipe 18 of the second feeder. The feeding pipe 18 of the second feeder then transports the mounting seat 3 to the transfer slot 19-1 of the second transfer seat 19. The transverse transfer drive cylinder 20 then drives the second transfer seat 19 to move laterally, pushing the mounting seat 3 directly above the pushing slot 15-1 of the pushing seat 15, causing the mounting seat 3 to fall into the pushing slot 15-1 below. Next, the vertical pressing drive cylinder 22 drives the pressing block 21 to move downward, and the pressing block 21 fixes the mounting seat 3 in the pushing slot 15-1 to prevent it from falling off during subsequent pushing.

[0060] Combination Figures 8-11 The top riveting drive mechanism includes a top riveting drive cylinder 23, which is fixedly mounted on the riveting machine frame 7. The telescopic rod of the top riveting drive cylinder 23 is fixedly connected to the top riveting seat 16.

[0061] Furthermore, the pushing drive mechanism is composed of a top riveting drive cylinder 23; an elastic pushing component is provided between the pushing seat 15 and the top riveting seat 16, the elastic pushing component includes a pushing spring 24 and a mounting guide rod, one end of the mounting guide rod is fixed on the top riveting seat 16, and the other end of the top riveting seat 16 slidably passes through the pushing seat 15; the pushing spring 24 is sleeved on the mounting guide rod, and the two ends of the pushing spring 24 abut against the pushing seat 15 and the top riveting seat 16 respectively; the pushing seat 15 is provided with a riveting clearance hole 15-2, which is concentric with the riveting hole of the mounting seat 3 located in the pushing groove 15-1; one end of the second riveting top rod 17 extends into the riveting clearance hole 15-2.

[0062] With the above structure, driven by the top riveting drive cylinder 23, the top riveting seat 16 pushes the push seat 15 closer to the cookware 1 via the push spring 24. When the mounting seat 3 in the push slot 15-1 of the push seat 15 is attached to the outer wall of the cookware 1 (the tail of the rivet 2 passes through the riveting hole of the mounting seat 3 and extends into the riveting clearance hole 15-2 of the push seat 15), the push seat 15 stops moving, the top riveting drive cylinder 23 continues to drive, and the top riveting seat 16 continues to move with the second riveting push rod 17 (at this time, the push spring 24 is compressed and deformed), so that the second riveting push rod 17 hits the tail of the rivet 2 along the riveting clearance hole 15-2 of the push seat 15, thereby realizing riveting.

[0065] During operation, the cookware 1 is inverted and transported to the riveting station. First, the second feeding mechanism automatically transports the mounting base 3 to the pushing slot 15-1 of the pushing seat 15. Then, the outer and inner riveting mechanisms are raised, so that the inner riveting mechanism is located inside the inner cavity of the cookware 1, and the outer riveting mechanism is located outside the cookware 1. At this time, the riveting hole of the cookware 1 is located between the first riveting rod 5 and the second riveting rod 17. The first feeding mechanism automatically transports the rivet 2 to the front of the first riveting rod 5. At this time, the head of the rivet 2 is close to the first riveting rod 5, and the tail of the rivet 2 is close to the inner wall of the cookware 1. The first pushing riveting drive mechanism pushes the first pushing riveting seat 4 and the first riveting rod 5 towards the inner wall of the cookware 1. The first riveting rod 5 pushes the rivet 2 close to the inner wall of the cookware 1, so that the tail of the rivet 2 passes through the riveting hole of the cookware 1 and presses the rivet 2 against the inner wall of the cookware 1, keeping it stationary.

[0066] The push-drive mechanism drives the push seat 15 to bring the mounting seat 3 closer to the cookware 1. During this process, the tail of the rivet 2 passes through the riveting hole of the mounting seat 3 until the mounting seat 3 is attached to the outer wall of the cookware 1. Then, the top riveting drive mechanism drives the top riveting seat 16 closer to the cookware 1, so that the second riveting top rod 17 presses against the tail of the rivet 2 at high speed.
