Description

Technical Field

[0001] This invention relates to the field of riveting technology, and more particularly to a riveting machine that can automatically add shims. Background Technology

[0002] Riveting machines are a new type of riveting equipment developed based on the principle of cold rolling. They are mechanical devices that can rivet items together. Compared with traditional welding and bolting methods, riveting has the following main advantages: good vibration resistance, effectively withstanding impact and fatigue loads; no thermal deformation, as the cold riveting process avoids structural deformation or material changes caused by high temperatures; reliable connection, as the rivet head is not easy to loosen after locking, and its sealing performance is better than that of bolts; suitable for dissimilar materials (such as metals and non-metals), and has no requirements on the thermal sensitivity of materials.

[0003] A search revealed a Chinese patent publication number CN214814521U, which discloses a riveting machine. The machine includes a base plate with several casters fixed to its lower surface. A support platform is located on one side of each caster, and an adjustment handle is rotatably mounted on the surface of the support platform. A shelf is located on the left side of the upper surface of the base plate, and a support frame is located on the right side. A storage cabinet is mounted on the support frame, with a light bulb fixed to the top of the cabinet. A storage bin is located below the support frame. A push-pull handle is located on the left side of the shelf. The riveting machine body is positioned between the shelf and the support frame. The riveting machine body includes a riveting machine mounting platform, a material platform, a left support plate, a right support plate, a top plate, a rotating frame support plate, a rotating frame, a rotating motor, a first cylinder, a punching rod, a riveting rod, a second cylinder, and a feeding track. An automatic oiling assembly is located above the material platform.

[0004] When riveting two parts together, the elastic deformation of the rivet and the metal workpiece can cause a slight rebound after the pressure is removed. This results in a small gap between the riveted parts, leading to a loose connection. Therefore, during riveting, an elastic metal washer needs to be placed at the tail of the rivet before riveting. The elastic force of the elastic metal washer compensates for the small gap and increases the tightness of the connection. However, the aforementioned patent cannot achieve automatic addition of the washer and still requires manual addition, which is inefficient. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a riveting machine that can automatically add shims.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A riveting machine capable of automatically adding shims includes a worktable, wherein a riveting seat is fixed to the top outer wall of the middle part of the worktable by bolts, a support frame is fixed to the top outer wall of the worktable by bolts, and a riveting mechanism is provided at the bottom front side of the support frame. The workbench is fixed to the outer wall of the riveting seat by bolts with a shim vibrating feeder. The outlet of the shim vibrating feeder is fixed to a shim slide by bolts. The top of the riveting seat is slidably connected to a shim transition channel. The side wall of the shim transition channel fits against the outlet end of the shim slide. A through groove matching the outlet size of the shim slide is opened on one side wall of the shim transition channel. A push plate is slidably connected to the inner wall of the shim transition channel. A feeding hole matching the size of the shim is opened at the bottom front side of the shim transition channel.

[0007] Preferably, the inner walls of the gasket transition channel on both sides of the through groove are chamfered.

[0008] Furthermore: the top outer wall of the workbench is fixed with a rivet vibrating feeder by bolts, the discharge port of the rivet vibrating feeder is fixed with a rivet slide, the inner wall of the riveting seat is provided with a slide groove, the other end of the rivet slide is engaged with the side wall of the slide groove, and the inner wall of the slide groove is slidably connected with a push plate two.

[0009] Based on the aforementioned scheme: the end of the push plate two is provided with an arc groove that matches the outer contour of the rivet.

[0010] A preferred embodiment of the aforementioned scheme is as follows: the riveting mechanism includes a second turntable, a slider, a lifting seat, and a riveting head. The lifting seat is slidably connected to the bottom front side of the support frame via a guide rod. The riveting head is fixed to the bottom outer wall of the lifting seat by bolts. The slider is slidably connected to the inner wall of the support frame. The second turntable is rotatably connected to the top outer wall of the support frame. A connecting rod is rotatably connected to the outer wall of the second turntable at a non-axial position. The other end of the connecting rod is rotatably connected to the top outer wall of the slider. A connecting rod is rotatably connected to the front side of the slider. The other end of the connecting rod is rotatably connected to the top outer wall of the lifting seat.

[0011] As a further aspect of the present invention: the turntable 2 is rotatably connected to the support frame via a main shaft, and a motor is driven to the bottom of the main shaft, the motor being fixed to the top outer wall of the worktable by bolts.

[0012] Meanwhile, the top outer wall of the workbench is equipped with a control cabinet for controlling the start and stop of the motor.

[0013] As a preferred embodiment of the present invention: the bottom of the support frame is rotatably connected to a turntable one via a main shaft, and the turntable one is located between push plate one and push plate two.

[0014] Meanwhile, a cam groove is provided on the top of the turntable, and a limit post is fixed at the end of the push plate. The limit post is movably limited and fitted inside the cam groove. A gear is rotatably connected to one side of the outer wall of the gasket transition channel. One side of the push plate is meshed with one side of the gear through teeth. A rack is meshed on the other side of the gear. The rack is fixed to the side wall of the rivet seat by bolts. The bottom of the turntable is provided with a cam groove, and the end of the push plate is fixed with a limit post, which is movably limited and matched with the bottom of the cam groove.

[0015] As a more preferred embodiment of the present invention: the convex direction of the first cam groove and the first turntable forms a 90-degree angle with the circumferential direction of the first turntable, and the convex position of the second cam groove is located upstream of the rotation direction of the first cam groove.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes a shim vibrating feeder for feeding and a shim slide for guiding the material. Then, it utilizes the transition effect of the shim transition channel and the pushing effect of the pusher plate to allow the shim to be placed around the rivet after the workpiece is placed on it, eliminating the need for manual placement and improving riveting efficiency.

[0017] 2. By setting up components such as a rivet vibratory feeder, a rivet slide, and a pusher plate, the present invention can realize automatic rivet feeding by utilizing the feeding of the rivet vibratory feeder, the guidance of the rivet slide, and the pushing of the pusher plate, thereby further improving the efficiency of the entire riveting operation.

[0018] 3. This invention utilizes the combination of teeth, gears, and racks, and employs the "planetary" principle, so that only the push plate can be driven to achieve synchronous movement between the gasket transition channel and the push plate, while also meeting the requirement that the movement speed of the gasket transition channel is slower than that of the push plate. This ensures relative sliding between the gasket transition channel and the riveting seat, and also relative sliding between the gasket transition channel and the push plate, thus ensuring the reliability of gasket feeding while simplifying the power arrangement.

[0019] 4. This invention utilizes the first limiting post and the first cam groove, and the second cam groove and the second limiting post to synchronously connect the first push plate and the first turntable, and the second push plate and the first turntable. Based on the synchronous rotation of the first turntable and the second turntable through the main shaft, by setting various angles and connection points, only the control cabinet is needed as the sole drive source to realize the extension and retraction of the gasket transition channel and the first push plate, the extension and retraction of the second push plate, and the lifting and lowering of the first cam groove. Moreover, the entire drive process can be run sequentially according to the requirements of the riveting process, increasing the synchronicity and linkage of the device. Attached Figure Description

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1: A riveting machine that can automatically add shims, such as Figure 1 - Figure 8 As shown, the workbench 1 is provided with a rivet seat 5 fixed to the top outer wall of the middle part of the workbench 1 by bolts, and a support frame 3 fixed to the top outer wall of the workbench 1 by bolts. A rivet mechanism is provided at the bottom front side of the support frame 3.

[0025] The outer wall of the workbench 1 located on one side of the riveting seat 5 is fixed with a shim vibrating feeder 2 by bolts. The outlet of the shim vibrating feeder 2 is fixed with a shim slide 7 by bolts. The top of the riveting seat 5 is slidably connected to a shim transition channel 11. The side wall of the shim transition channel 11 is in contact with the outlet end of the shim slide 7. A through groove 13 matching the outlet size of the shim slide 7 is opened on one side wall of the shim transition channel 11. A push plate 12 is slidably connected to the inner wall of the shim transition channel 11. A discharge hole 32 matching the size of the shim is opened at the bottom front side of the shim transition channel 11.

[0026] When using this device, first place the rivet on the top front side of the riveting seat 5, then align the rivet holes of the riveted workpieces with the rivet and attach them, while simultaneously using the riveting seat 5 for support and fixation. During this process, the gasket transition channel 11 and push plate 12 are both in a retracted state, and the through groove 13 is aligned with the outlet of the gasket slide 7. After the gasket vibrating feeder 2 vibrates and feeds the gasket, the gasket slides along the gasket slide 7 under gravity, enters the interior of the gasket transition channel 11 through the through groove 13, and then the push plate 12 slides forward relative to the gasket transition channel 11, pushing the gasket towards the gasket. The shim transition channel 11 is pushed at the unloading hole 32, and at the same time, the shim transition channel 11 also slides forward to align the unloading hole 32 with the rivet. After the unloading hole 32 is located above the coaxial part of the rivet, the push plate 12 also pushes the shim to the unloading hole 32. The shim is lowered by gravity and fits against the top workpiece and is sleeved on the outside of the rivet. During the pushing process, the opening of the shim slide 7 is blocked by the side wall of the shim transition channel 11. Then the shim transition channel 11 and the push plate 12 retract to avoid the top space of the rivet. Then the riveting mechanism performs the riveting operation.

[0027] This device utilizes the shim vibrating feeder 2 for feeding and the shim slide 7 for guiding the material. Then, it utilizes the transition effect of the shim transition channel 11 and the pushing effect of the push plate 12 to allow the shims to be placed around the rivets after the workpiece is placed on the rivets, eliminating the need for manual placement and increasing riveting efficiency.

[0028] To solve the problem of separation effect; such as Figure 3 As shown, the inner walls of the gasket transition channel 11 on both sides of the through groove 13 are provided with chamfers 14. The sharpness of the chamfers 14 makes it easy for the two gaskets that are in contact with each other to separate when the gasket transition channel 11 moves.

[0029] To solve the problem of rivet feeding; such as Figure 4 As shown, the top outer wall of the workbench 1 is fixed with a rivet vibrating feeder 4 by bolts. The discharge port of the rivet vibrating feeder 4 is fixed with a rivet slide 6. The inner wall of the riveting seat 5 is provided with a slide groove 15. The other end of the rivet slide 6 is engaged with the side wall of the slide groove 15, and the inner wall of the slide groove 15 is slidably connected with a push plate 2 17.

[0030] The end of the push plate 17 is provided with an arc groove 16 that matches the outer contour of the rivet.

[0031] In the initial stage of operation, the rivet vibrating feeder 4 conveys the rivet head downwards through vibration. The rivet slides along the rivet slideway 6 under the action of gravity, thus sliding from the side of the slideway 15 to the inside of the slideway 15. Then, the push plate 17 slides along the slideway 15 and pushes the rivet to the end of the slideway 15, which is the riveting station, through the cooperation of the arc groove 16 with the base of the rivet. At the same time, the side wall of the push plate 17 will block the subsequent rivets to prevent them from entering the slideway 15.

[0032] This device, by setting up components such as a rivet vibrating feeder 4, a rivet slide 6, and a pusher plate 17, can automatically feed rivets by utilizing the feeding of the rivet vibrating feeder 4, the guidance of the rivet slide 6, and the pushing of the pusher plate 17, thereby further increasing the efficiency of the entire riveting operation.

[0033] To solve the problem of riveting and feeding; such as Figure 7 As shown, the riveting mechanism includes a second turntable 23, a slider 25, a lifting seat 28, and a riveting head 29. The lifting seat 28 is slidably connected to the bottom front side of the support frame 3 via a guide rod 26. The riveting head 29 is fixed to the bottom outer wall of the lifting seat 28 by bolts. The slider 25 is slidably connected to the inner wall of the support frame 3. The second turntable 23 is rotatably connected to the top outer wall of the support frame 3. A connecting rod 24 is rotatably connected to the outer wall of the second turntable 23 at a non-axial position. The other end of the connecting rod 24 is rotatably connected to the top outer wall of the slider 25. A connecting rod 27 is rotatably connected to the front side of the slider 25. The other end of the connecting rod 27 is rotatably connected to the top outer wall of the lifting seat 28.

[0034] To solve driver issues, such as Figure 8 As shown, the turntable 23 is rotatably connected to the support frame 3 via the main shaft 30, and the bottom of the main shaft 30 is connected to the motor 31. The motor 31 is fixed to the top outer wall of the worktable 1 by bolts. When the motor 31 is started, it can drive the turntable 23 to rotate.

[0035] The top outer wall of the workbench 1 is equipped with a control cabinet 33 for controlling the start and stop of the motor 31.

[0036] In this embodiment, the specific types of the shim vibratory feeder 2 and the rivet vibratory feeder 4 are not limited. Vibratory feeders are existing technology, and shims and rivets are conventional components. For the shim vibratory feeder 2 for shim feeding, a vibratory plate as described in patent publication number CN221458920U can be used. As for the rivet and bolt structure type, a vibratory feeding mechanism as described in patent publication number CN108436426B can be used. Since these are all existing mature technologies with wide applications, and are also conventional knowledge and common methods for those skilled in the art, this embodiment only applies them functionally and does not involve any creative effort, so they will not be described in detail.

[0037] When turntable 23 rotates, it can drive slider 25 to slide forward through connecting rod 24, thereby driving lifting seat 28 to descend through connecting rod 27. The riveting head 29 and riveting seat 5 limit the upper and lower limit of the rivet, causing the rivet to deform and rivet.

[0038] In this embodiment, during initial operation, the rivet vibratory feeder 4 vibrates to feed the rivet head downwards. The rivet, under gravity, slides along the rivet slideway 6, moving from the side of the slide groove 15 into its interior. Then, the push plate 17 slides along the slide groove 15, pushing the rivet to the end of the slide groove 15 (the riveting station) through the engagement of the arc groove 16 with the rivet's base. Simultaneously, the side wall of the push plate 17 blocks subsequent rivets, preventing them from entering the slide groove 15. The rivet holes of the riveted workpieces are then aligned with the rivet sleeves, and supported and fixed by the riveting seat 5. During this process, the gasket transition channel 11 and the push plate 12 are both in a contracted state, and the through groove 13 is aligned with the outlet of the gasket slideway 7. After the gasket vibratory feeder 2 vibrates and feeds the gasket, the gasket, under gravity, slides along the gasket slideway 7, entering the interior of the gasket transition channel 11 through the through groove 13. Subsequently, the push plate 12 transitions relative to the gasket. The channel 11 slides forward, pushing the shim towards the unloading hole 32 of the shim transition channel 11. At the same time, the shim transition channel 11 also slides forward, aligning the unloading hole 32 with the rivet. After the unloading hole 32 is located coaxially above the rivet, the push plate 12 also pushes the shim to the unloading hole 32. The shim falls down under gravity and adheres to the top workpiece and is fitted onto the outside of the rivet. During the pushing process, the opening of the shim slide 7 is blocked by the side wall of the shim transition channel 11. Then the shim transition channel 11 and the push plate 12 retract, making way for the top space of the rivet. Then the motor 31 is started. When the motor 31 starts, it can drive the turntable 23 to rotate. When the turntable 23 rotates, it can drive the slider 25 to slide forward through the connecting rod 24, thereby driving the lifting seat 28 to descend through the connecting rod 27. The rivet is deformed by the upper and lower limit punching of the riveting head 29 and the riveting seat 5, and riveting is performed.

[0039] Example 2: A riveting machine that can automatically add shims, such as Figure 1 - Figure 8 As shown, in order to solve the joint drive problem, this embodiment makes the following improvements based on embodiment 1: the bottom of the support frame 3 is rotatably connected to a turntable 20 via a main shaft 30, and the turntable 20 is located between push plate 12 and push plate 17.

[0040] The top of the turntable 20 is provided with a cam groove 19, and the end of the push plate 12 is fixed with a limit post 18. The limit post 18 is movably limited and fitted inside the cam groove 19. A gear 9 is rotatably connected to one side of the outer wall of the gasket transition channel 11. One side of the push plate 12 is meshed with one side of the gear 9 through teeth 8. The other side of the gear 9 is meshed with a rack 10. The rack 10 is fixed to the side wall of the rivet seat 5 by bolts.

[0041] The bottom of the turntable 20 is provided with a cam groove 21, and the end of the push plate 17 is fixed with a limit post 22, which is movably limited and matched with the bottom of the cam groove 21.

[0042] The cam groove 19 and the convex direction of the turntable 20 form a 90-degree angle with the circumferential direction of the turntable 20, and the convex position of the cam groove 21 is located upstream of the rotation direction of the cam groove 19.

[0043] The working steps of this embodiment are as follows: S1: First, the worker starts the motor 31 through the control cabinet 33. At this time, the motor 31 rotates, the shim transition channel 11 and the push plate 12 are in the retracted state, and the push plate 17 is in the process of changing from the retracted state to the extended state. During this process, the cam groove 19 is in the upward movement, and at the same time, the push plate 17 pushes out the rivet until it is completely pushed out. Then the motor 31 stops. At this time, the worker aligns the rivet hole of the workpiece with the rivet and places it and supports and fixes it with the rivet seat 5. S2: Subsequently, the worker starts the motor 31 again through the control cabinet 33. At this time, the motor 31 rotates. During this process: S21: Push plate 2 17 will gradually shrink from the extended state to the contracted state, and push plate 12 will move from the contracted state to the extended state. When push plate 12 moves, it will drive gear 9 to rotate due to the meshing of teeth 8 and gear 9, and then drive the shim transition channel 11 to slide through the meshing of gear 9 and rack 10. The sliding speed of shim transition channel 11 is half the sliding speed of push plate 12. During this process, the shim is fed. S22: During the gasket feeding process, the cam groove 19 is in a state of first rising and then falling, and after the gasket feeding is completed, the height of the cam groove 19 will not interfere with the top of the gasket transition channel 11. S3: After the gasket is fed, the motor 31 will continue to rotate. At this time, the gasket transition channel 11 and the push plate 12 will retract, and the cam groove 19 will descend until it contacts the rivet. Then, it will limit the rivet to the riveting seat 5, thus completing the riveting operation.

[0044] This device, by utilizing the cooperation of teeth 8, gear 9 and rack 10, and employing the "planetary" principle, can achieve synchronous movement of the gasket transition channel 11 and the push plate 12 by only driving the push plate 12. At the same time, it can also meet the requirement that the movement speed of the gasket transition channel 11 is slower than that of the push plate 12, ensuring that the gasket transition channel 11 slides relative to the riveting seat 5 and that the gasket transition channel 11 also slides relative to the push plate 12. This ensures the reliability of gasket feeding while simplifying the power arrangement.

[0045] In addition, this device uses the limiting post 18 and the cam groove 19, and the cam groove 21 and the limiting post 22 to synchronously drive the push plate 12 and the turntable 20, and the push plate 27 and the turntable 20. Based on the synchronous rotation of the turntable 20 and the turntable 23 through the main shaft 30, by setting various angles and connection points, only the control cabinet 33 is needed as the sole drive source to realize the extension and retraction of the gasket transition channel 11 and the push plate 12, the extension and retraction of the push plate 27, and the lifting and lowering of the cam groove 19. Moreover, the entire drive process can be run sequentially according to the requirements of the riveting process, which increases the synchronicity and linkage of the device.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
