Description

Technical Field

[0001] The present invention belongs to the technical field of circuit breaker production, and specifically relates to a riveting device for the production of miniature circuit breakers. Background Art

[0002] During the processing and production of miniature circuit breakers, it is necessary to perform riveting on the components inside them through a riveting device. Usually, rivets, pins, and riveting nuts are used for riveting. Most of the existing riveting devices for the production of miniature circuit breakers adopt assembly line production. First, the rivets or riveting nuts are placed into the corresponding riveting holes on the components by a blanking machine, and then conveyed to the riveting device through a conveying mechanism. Then, they are pushed into the riveting device for riveting by means of an electric push rod or the like. However, when the production speed is relatively high, when the electric push rod pushes the circuit breaker components onto the riveting device, the rivets or riveting nuts in the riveting holes on the components are likely to shift or break away from the riveting holes under the action of inertia. This will result in the phenomenon of skewed riveting or non-riveting after the riveting device performs riveting, thus leading to low quality of the processed miniature circuit breakers. Moreover, the frequent skewed riveting of the riveting device will damage the riveting head, resulting in uneven riveting.

[0003] Therefore, a riveting device for the production of miniature circuit breakers is proposed to solve the above problems. Summary of the Invention

[0008] Preferably, the pressing mechanism includes a mounting block. The mounting block is mounted above the riveting table.

[0009] Preferably, the pressing mechanism further includes a limiting frame. The limiting frame is mounted on the riveting table. A movable block is slidably mounted on the limiting frame. A first elastic member is connected between the limiting frame and the movable block. A fixed frame is connected to one side of the movable block. An inclined plane block is rotatably mounted on the fixed frame. A resisting block capable of abutting against the inclined plane block is connected to the fixed frame.

[0010] Preferably, an L-shaped rod is connected to the outside of the movable block. The other end of the L-shaped rod is connected to a connecting block. An arc-shaped clamping block capable of being clamped inside the clamping seat is sleeved inside the connecting block. A second elastic member is connected between the arc-shaped clamping block and the inner wall of the connecting block.

[0011] Preferably, a movable block is slidably sleeved inside the riveting table. A first spring is connected to one side of the movable block, and the other end of the first spring can be connected to the inner wall of the riveting table. Card slots are provided inside both sides of the movable block. The other end of the movable block is connected to a connecting rod, and the other end of the connecting rod is connected to a resisting plate. Electric push rods I are mounted on both sides inside the riveting table, and the output ends of the electric push rods I are connected to abutting heads.

[0012] Preferably, magnetic clamping blocks are movably sleeved on both sides inside the riveting table. A second spring is connected between the magnetic clamping blocks and the inner wall of the riveting table. Electromagnetic elements facing the magnetic clamping blocks are connected to both sides of the inner wall of the riveting table.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a pressing plate and a movable cylinder, and a conveying mechanism conveys the circuit breaker parts to the riveting mechanism. The second electric push rod drives the push head to move close to the circuit breaker parts. Due to the movement of the push head, the pressing mechanism can be driven to move together, and the round tube and the extrusion block can be driven to move, so that the inclined surface of the extrusion block abuts and squeezes the inclined surface block to drive the fixed frame, the movable block and the L-shaped rod to move. At the same time, the elastic member 1 is compressed. Due to the movement of the L-shaped rod, the connecting block and the arc surface block will be separated from the clamping seat. At this time, the tension spring 2 in the stretched state will be released due to the recovery effect of the elastic force. The push rod, the connecting plate and the push rod are driven to move to one side of the movable cylinder, and the movable cylinder is pushed to retract into the connecting cylinder to apply pressure to the cylinder, so as to push the piston rod and the pressure plate down and make the pressure plate abut against the rivet or nut on the circuit breaker component. This design can press the rivet or nut on the circuit breaker component to avoid the rivet or nut being offset or separated due to the inertia of the push head, thereby avoiding the subsequent riveting assembly from being crooked or not riveted during riveting, thereby protecting the rivet joints on the riveting assembly and improving the production quality of small circuit breakers.

[0014] The present invention provides a pressing plate, a butt plate and a butt head. When the push head pushes the circuit breaker component pressed by the butt pressing mechanism to move, the bottom of the pressing plate is a smooth surface coated with an oil film, so that the pressed component can move at the bottom of the pressing plate. When the component moves to butt against the butt plate, the component can be corrected under the mutual extrusion of the push head and the butt plate. After the correction is completed, the butt plate, the connecting rod and the moving block are pressed and pushed to move toward the inside of the riveting table. At the same time, when the spring is compressed and the moving block moves to the magnetic card block, the magnetic card block is squeezed to shrink. Then, under the elastic recovery action of the electromagnetic element, the magnetic block can be pushed out and clamped in the moving block to fix the abutment plate. At this time, the circuit breaker parts will be located on the riveting table. Due to the operation of the electric push rod 1, the two abutment heads can be driven to move toward each other, and the parts can be centered and clamped. This design can ensure that the rivets or nuts on the parts can be centered and corrected under the pressure of the pressure plate, and due to the continuous pressure of the pressure plate, it can be ensured that the rivets or nuts on the parts will not be offset or detached due to inertia during the centering and correction process.

[0015] In the present invention, by providing air holes and circular tubes, after the components of the circuit breaker are aligned, the second electric push rod will drive the push head and the pressing mechanism to move back to their original positions. When the sleeve moves and abuts against and pushes the sealing sleeve to move, at the same time, the third spring is compressed. When the circular tube moves to communicate with the air holes, the sealing of the cylinder will be released. At this time, under the restoring force of the first tension spring, the pressing plate and the piston rod will be pulled to contract and move upward to reset, and the movable cylinder will be pushed out again by air pressure. While the sleeve resumes moving, the fixed rod and the extrusion block will reset together. When the extrusion block moves to the inclined block, the extrusion block will first abut against and squeeze the inclined block and the arc block to rotate to ensure the smooth passage of the extrusion block, so as to prevent the arc surface clamping block from moving out of the card seat. When the extrusion block passes the inclined block, under the elastic force of the arc spring, it will drive the inclined block and the arc block to reset, so that the pressing plate and the movable cylinder can be restored to their initial states, facilitating subsequent operation again.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some 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.

[0019] As Figures 1 to 11 shown, the present invention provides a riveting device for the production of miniature circuit breakers, including a conveying mechanism 1, a riveting mechanism 2, an electric push rod 2 3, a pushing head 4, a pressing mechanism 5, two air supply mechanisms 6 and two pressing mechanisms 7; The riveting mechanism 2 is connected behind the conveying mechanism 1, the electric push rod 2 3 is installed in front of the conveying mechanism 1, the pushing head 4 is connected to the output end of the electric push rod 2 3, the pressing mechanism 5 is arranged on the pushing head 4, the two air supply mechanisms 6 are arranged on the conveying mechanism 1 and the riveting mechanism 2 and on both sides of the pressing mechanism 5, and the two pressing mechanisms 7 are respectively arranged on both sides above the riveting table 21 and can push the air supply mechanism 6; The riveting mechanism 2 includes a riveting table 21, the riveting table 21 is connected to the conveying mechanism 1, and a riveting assembly 22 is installed above the riveting table 21; The pressing mechanism 5 includes a connecting frame 51. The connecting frame 51 is connected to the push head 4. Four cylinders 52 are fixedly sleeved inside the connecting frame 51. A piston rod 53 is sleeved inside the cylinder 52. The bottom end of the piston rod 53 is connected to a pressing plate 54 located below the cylinder 52. The top ends of the four cylinders 52 are all connected to an I-shaped pipe 56. A first tension spring 55 is connected between the connecting frame 51 and the pressing plate 54.

[0020] Adopting the above solution: When air pressure presses on the cylinder 52 through the I-shaped pipe 56, it will push the piston rod 53 and the pressing plate 54 to descend and make the pressing plate 54 abut against the rivets or nuts on the circuit breaker components. At the same time, the first tension spring 55 is stretched, so that the rivets or nuts are pressed against the circuit breaker components, avoiding the deviation or detachment of the rivets or nuts under the action of the inertia of the push head 4.

[0021] As Figure 5 and Figure 6 As shown, the air supply mechanism 6 includes a fixed pipe 61. The two ends of the bottom of the fixed pipe 61 are respectively connected to the conveying mechanism 1 and the riveting table 21. An air hole 68 is opened on the fixed pipe 61. The outside of the fixed pipe 61 is movably sleeved with a sleeve 64 located outside the air hole 68. A circular pipe 65 is connected and communicated between the sleeve 64 and the I-shaped pipe 56. The outside of the fixed pipe 61 is movably sleeved with a sealing sleeve 66 that can abut against the sleeve 64. The other end of the sealing sleeve 66 is connected to a third spring 67 located outside the fixed pipe 61. The other end of the third spring 67 is connected to the fixed pipe 61. One side of the fixed pipe 61 is communicated with a connecting cylinder 62 located above the riveting table 21. An activity cylinder 63 is movably sleeved inside the connecting cylinder 62.

[0022] Adopting the above solution: When the push head 4 pushes the circuit breaker component pressed by the pressing mechanism 5 to move, the sleeve 64 will move along the fixed pipe 61. At this time, under the restoring force of the third spring 67 in the compressed state, it will push the sealing sleeve 66 to move together with the sleeve 64. During this process, the circular pipe 65 can always be connected and communicated with the air hole 68. When the circular pipe 65 and the air hole 68 are misaligned and disconnected, the movement of the sealing sleeve 66 can completely seal the air hole 68. At the same time, the interference fit between the fixed pipe 61 and the sleeve 64 can seal the circular pipe 65, the I-shaped pipe 56 and the cylinder 52.

[0023] As Figures 5 to 7 As shown, a fixed rod 69 is connected to the outside of the sleeve 64. The other end of the fixed rod 69 is connected to an extrusion block 610.

[0024] Adopting the above solution: Due to the movement of the push head 4, it can drive the pressing mechanism 5 to move together, and drive the fixed rod 69 and the extrusion block 610 to move together through the movement of the circular pipe 65 and the sleeve 64.

[0025] As Figures 7 to 9As shown in the figure, the pressing mechanism 7 includes a mounting block 71. The mounting block 71 is installed above the riveting table 21. A ejector rod 72 that can abut against the movable cylinder 63 is movably sleeved in the mounting block 71. The other end of the ejector rod 72 is connected to a connecting plate 73. A second tension spring 74 located outside the ejector rod 72 is connected between the connecting plate 73 and the inner wall of the mounting block 71. The outer end of the connecting plate 73 is connected to a clamping seat 718. One side of the connecting plate 73 is connected to a resisting rod 75 that passes through the riveting assembly 22.

[0026] Adopting the above scheme: When the elastic force of the second tension spring 74 is released, it will drive the ejector rod 72, the connecting plate 73 and the resisting rod 75 to move towards one side of the movable cylinder 63, and push the movable cylinder 63 to contract into the connecting cylinder 62. Pressure is applied to the cylinder 52 through the fixed pipe 61, the air hole 68, the round pipe 65 and the I-shaped pipe 56, pushing the piston rod 53 and the pressing plate 54 to descend and making the pressing plate 54 abut against the rivet or nut on the circuit breaker component.

[0027] As Figures 7 to 9 shown in the figure, the pressing mechanism 7 further includes a limiting frame 76. The limiting frame 76 is installed on the riveting table 21. A movable block 77 is slidably installed on the limiting frame 76. An elastic member 78 is connected between the limiting frame 76 and the movable block 77. One side of the movable block 77 is connected to a fixed frame 79. An inclined block 710 is rotatably installed on the fixed frame 79. A resisting block 711 that can abut against the inclined block 710 is connected to the fixed frame 79. An arc-shaped block 712 that can be connected to the inclined block 710 is movably sleeved in the fixed frame 79. The other end of the arc-shaped block 712 is connected to an arc-shaped spring 713 located inside the fixed frame 79. The other end of the arc-shaped spring 713 can be connected to the inner wall of the fixed frame 79.

[0028] Adopting the above scheme: When the extrusion block 610 moves, it can abut against and squeeze the inclined block 710. Since the inclined block 710 is restricted by the abutment of the resisting block 711 and cannot rotate, it drives the fixed frame 79, the movable block 77 and the L-shaped rod 714 to move along the limiting frame 76. At the same time, the elastic member 78 is compressed. When the extrusion block 610 resets, it will first abut against and squeeze the inclined block 710 and the arc-shaped block 712 to rotate to ensure the smooth passage of the extrusion block 610, so as to avoid the fixed frame 79, the movable block 77 and the L-shaped rod 714 from moving along the limiting frame 76, thus forming a one-way trigger form.

[0029] As Figures 7 to 9 shown in the figure, an L-shaped rod 714 is connected to the outside of the movable block 77. The other end of the L-shaped rod 714 is connected to a connecting block 715. An arc-shaped surface clamping block 716 that can be clamped in the clamping seat 718 is sleeved in the connecting block 715. An elastic member 717 is connected between the arc-shaped surface clamping block 716 and the inner wall of the connecting block 715.

[0030] Adopting the above solution: When the fixed frame 79, the movable block 77, and the L-shaped rod 714 move along the limiting frame 76, the first elastic member 78 will be compressed. Due to the movement of the L-shaped rod 714, it will drive the connecting block 715 and the arc-shaped clamping block 716 to disengage from the clamping seat 718, thereby releasing the fixation of the ejector rod 72.

[0031] As Figure 10 and Figure 11 shown, a movable block 24 is slidably sleeved inside the riveting table 21. One side of the movable block 24 is connected to a first spring 27, and the other end of the first spring 27 can be connected to the inner wall of the riveting table 21. Card slots are provided inside both sides of the movable block 24. The other end of the movable block 24 is connected to a connecting rod 25, and the other end of the connecting rod 25 is connected to a pressing plate 26. Electric push rods 23 are installed on both sides inside the riveting table 21, and the output ends of the electric push rods 23 are connected to abutting heads 211.

[0032] Adopting the above solution: When the component moves to abut against the pressing plate 26, under the mutual extrusion of the pushing head 4 and the pressing plate 26, the component can be corrected. After the correction is completed, the pressing plate 26, the connecting rod 25, and the movable block 24 are squeezed and pushed to move inside the riveting table 21. At the same time, the first spring 27 is compressed, so that the circuit breaker component will be located on the riveting table 21. Due to the operation of the electric push rod 23, the two abutting heads 211 can be driven to move towards each other, and the component can be centered and clamped, thereby ensuring that the rivets or nuts on the component can be centered and corrected under the pressure of the pressing plate 54.

[0033] As Figure 10 and Figure 11 shown, magnetic clamping blocks 28 are movably sleeved on both sides inside the riveting table 21. A second spring 210 is connected between the magnetic clamping blocks 28 and the inner wall of the riveting table 21. Electromagnetic elements 29 facing the magnetic clamping blocks 28 are connected to both sides of the inner wall of the riveting table 21.

[0034] Adopting the above solution: When the movable block 24 moves to the magnetic clamping block 28, it will squeeze the magnetic clamping block 28 to contract. Subsequently, under the elastic recovery of the electromagnetic element 29, the magnetic clamping block 28 can be ejected and clamped inside the movable block 24, thereby fixing the movable block 24 and the pressing plate 26.

[0035] The working principle and usage process of the present invention: During use, the conveying mechanism 1 conveys the circuit breaker components to the riveting mechanism 2. The second electric push rod 3 drives the push head 4 to move closer to the circuit breaker components. Due to the movement of the push head 4, the pressing mechanism 5 can be driven to move together, and the round tube 65, the sleeve 64, the fixing rod 69, and the extrusion block 610 are driven to move, so that the inclined surface of the extrusion block 610 abuts against and squeezes the inclined surface block 710. Since the inclined surface block 710 is restricted by the abutment of the abutting block 711 and cannot rotate, the fixing frame 79, the movable block 77, and the L-shaped rod 714 are driven to move along the limiting frame 76. At the same time, the first elastic member 78 is compressed. Due to the movement of the L-shaped rod 714, the connecting block 715 and the arc-shaped clamping block 716 are driven to disengage from the clamping seat 718. At this time, the second tension spring 74 in the stretched state will drive the ejector rod 72, the connecting plate 73, and the abutting rod 75 to move to one side of the movable cylinder 63 due to the recovery of the elastic force, and push the movable cylinder 63 to contract into the connecting cylinder 62, and press the cylinder 52 through the fixing tube 61, the air hole 68, the round tube 65, and the I-shaped tube 56, and push the piston rod 53 and the pressing plate 54 to descend and make the pressing plate 54 abut against the rivet or nut on the circuit breaker component. At the same time, the first tension spring 55 is stretched, so that the rivet or nut presses on the circuit breaker component, avoiding the offset or detachment of the rivet or nut under the action of the pushing inertia of the push head 4.

[0036] When the push head 4 drives the pressing mechanism 5 to press the circuit breaker component to move, the sleeve 64 will move along the fixing tube 61. At this time, under the action of the recovery of the elastic force of the third spring 67 in the compressed state, the sealing sleeve 66 will be pushed to move together with the sleeve 64. During this process, the round tube 65 can always be communicated with the air hole 68, ensuring that the pressing plate 54 can smoothly press on the rivet or nut on the circuit breaker component. When the round tube 65 and the air hole 68 are misaligned and disconnected, the movement of the sealing sleeve 66 can completely seal the air hole 68. At the same time, the interference fit between the fixing tube 61 and the sleeve 64 can seal the round tube 65, the I-shaped tube 56, and the cylinder 52, so that the sleeve 64 can maintain the pressing state.

[0037] When the push head 4 drives the pressing mechanism 5 to press the circuit breaker component to move, since the bottom of the pressing plate 54 is a smooth surface with an oil film, the pressed component can move under the bottom of the pressing plate 54. When the component moves to abut against the abutting plate 26, under the mutual extrusion of the push head 4 and the abutting plate 26, the component can be corrected. After the correction is completed, the abutting plate 26, the connecting rod 25, and the moving block 24 are extruded and pushed to move into the riveting table 21. At the same time, the first spring 27 is compressed. When the moving block 24 moves to the magnetic clamping block 28, it will squeeze the magnetic clamping block 28 to contract. Subsequently, under the action of the recovery of the elastic force of the electromagnetic element 29, the magnetic clamping block 28 can be ejected and clamped in the moving block 24 to fix the abutting plate 26. At this time, the circuit breaker component will be located on the riveting table 21. Due to the operation of the first electric push rod 23, the two abutting heads 211 can be driven to move towards each other, and the component can be centered and clamped.

[0038] When the pusher 4 pushes the breaker component moved by the pressing mechanism 5, the connecting frame 51 will move and abut against the abutting rod 75, and push the abutting rod 75, the connecting plate 73 and the ejector rod 72 to contract and move. At the same time, the second tension spring 74 is stretched. Due to the movement of the connecting plate 73, the clamping seat 718 will be driven to move together. When the clamping seat 718 moves to the arc-shaped clamping block 716, it will first squeeze the arc-shaped clamping block 716 to contract into the connecting block 715. Subsequently, under the action of the elastic force recovery of the second elastic member 717, it will push the arc-shaped clamping block 716 to be clamped in the clamping seat 718, and reset and fix the ejector rod 72.

[0039] After the breaker components are centered, the second electric push rod 3 will drive the pusher 4 and the pressing mechanism 5 to reset and move. When the sleeve 64 moves and abuts against and pushes the closing sleeve 66 to move, and at the same time the third spring 67 is compressed. When the round tube 65 moves to communicate with the air hole 68, the closing of the cylinder 52 will be released. At this time, under the action of the elastic force recovery of the first tension spring 55, it will pull the pressing plate 54 and the piston rod 53 to contract and move upward and reset, and push the movable cylinder 63 to extend again through air pressure. At the same time as the sleeve 64 resumes moving, the fixed rod 69 and the extrusion block 610 will reset together. When the extrusion block 610 moves to the inclined plane block 710, the extrusion block 610 will first abut against and squeeze the inclined plane block 710 and the arc block 712 to rotate to ensure the smooth passage of the extrusion block 610, so as to prevent the arc-shaped clamping block 716 from moving out of the clamping seat 718. When the extrusion block 610 passes the inclined plane block 710, under the action of the elastic force of the arc-shaped spring 713, it will drive the inclined plane block 710 and the arc block 712 to reset.

[0040] After the pusher 4 is reset, the riveting and pressing assembly 22 operates to perform riveting and pressing on the rivets or nuts on the components. After the riveting and pressing is completed, the electromagnetic element 29 operates, which will magnetically attract and contract the magnetic clamping block 28. At the same time, the second spring 210 is compressed, releasing the clamping between the moving block 24 and the magnetic clamping block 28, and under the action of the elastic force recovery of the first spring 27, it will push the moving block 24, the connecting rod 25 and the abutting plate 26 to move outward. Through the abutting plate 26, the components completed with riveting can be pushed back onto the conveying mechanism 1 again, so as to convey them to the next process.
