Description

Technical Field

[0001] This utility model relates to the field of riveting device technology, and in particular to a servo riveting device with an alternating platform. Background Technology

[0002] Traditional riveting equipment relies primarily on manual loading, with some machines employing simple mechanical assistance. Specifically, operators manually place the workpiece into the fixture, then position the rivet on a vibratory feeder or a dedicated feeder, and the machine's movement completes the loading process. Some existing machines also utilize multi-platform loading mechanisms for alternating loading, enabling continuous operation. While this design speeds up loading, its large size hinders adjustments to the layout of other internal structures, impeding further improvements. It also occupies more space during transport, increasing logistics costs. Furthermore, its large size and uneven weight distribution make it less flexible and convenient than smaller, more compact mechanisms, potentially requiring additional reinforcement or adjustments to the installation schedule, thus impacting efficiency. Therefore, this mechanism presents inconveniences in terms of transportation, installation, and use. Utility Model Content

[0003] This utility model addresses the shortcomings of the prior art and aims to solve at least one of the aforementioned technical defects. In view of this, this application provides a servo riveting device with alternating platforms, which can improve the layout flexibility of the device and solve the problem of high space occupancy of multi-platform loading mechanisms.

[0004] This utility model provides a servo riveting device with an alternating platform, including an alternating feeding mechanism, wherein the alternating feeding mechanism includes a first platform component and a second platform component;

[0005] The first platform component includes a first platform, a lifting cylinder connected to the bottom of the first platform, and a first guide slide component connected to the bottom of the lifting cylinder;

[0006] The second platform component includes a second platform, a second guide slide assembly connected to the bottom of the second platform, and a base disposed at the bottom of the second guide slide assembly. The first guide slide assembly is disposed below the base, the lifting cylinder is located outside the base, and the first platform is located above the second guide slide assembly.

[0007] The first and second platforms are used to mount workpiece fixtures. The first platform is vertically raised and lowered by a lifting cylinder, and then horizontally displaced by a first guide slide assembly, allowing it to move above the second platform. Simultaneously, the second platform can be horizontally displaced using a second guide slide assembly, allowing it to interchange positions with the first platform, enabling alternating loading of workpieces after installation. Furthermore, the lifting cylinder is positioned on the outside of the base for easy installation, debugging, and routine maintenance. The second guide slide assembly, in conjunction with the base, provides a stable support foundation, further enhancing motion stability.

[0008] Preferably, the first guide slide assembly includes a sliding plate, a first slider, and a guide rail. The top of the guide rail is slidably connected to the first slider, the top of the first slider is fixed to the sliding plate, and the sliding plate is in contact with the bottom of the lifting cylinder.

[0009] The second guide slide assembly includes a second slider and a slide rail. The slide rail is mounted on the top of the base, and the top of the slide rail is slidably connected to the second slider. The second slider is connected to the bottom of the second platform.

[0010] Both the guide rail and the slide rail serve a guiding function, providing displacement direction constraints for the first and second platforms to achieve precise material loading. Secondly, the sliding plate is responsible for mounting the lifting cylinder to provide a stable support platform; multiple lifting cylinders can be set up for coordinated operation. The base raises the height of the second slider and the slide rail, preventing collisions with the sliding plate during sliding and increasing structural rationality.

[0011] Preferably, the base is provided with a synchronization mechanism, which includes a synchronous motor, a rotating shaft and a synchronous belt. The synchronous motor and the rotating shaft are both mounted on the base. The synchronous belt is wound around the drive end of the synchronous motor and the rotating shaft. The synchronous belt connects the first guide slide assembly and the second platform.

[0012] In this mechanism, a synchronous motor and a rotating shaft tension a synchronous belt, which in turn connects the first guide slide assembly and the second guide slide assembly to achieve the effect of synchronizing the movement of the two components. This replaces manual movement of the first and second platforms, making the alternating feeding mechanism intelligent.

[0013] Preferably, the base is further provided with a lifting cylinder, the drive end of which abuts against the bottom of the second platform.

[0014] Among them, the lifting cylinder can vertically lift the second platform, which can cooperate with the riveting structure during the workpiece riveting process to squeeze the workpiece, increase the tightness of the connection between the workpieces, and thus improve the riveting quality.

[0015] Preferably, the device further includes a frame and a riveting mechanism, the riveting mechanism being slidably connected to the frame, and the alternating feeding mechanism being mounted on the frame and located below the riveting mechanism.

[0016] The riveting mechanism is slidably connected to the frame, allowing it to move flexibly along a preset track. This enables it to apply pressure to the workpiece, and the alternating feeding platform below it can further increase the pressure and optimize the riveting effect.

[0017] Preferably, the riveting mechanism includes a riveting head, a rotating spindle fixed to the top of the riveting head, a servo motor connected above the rotating spindle, and a slide fixed on the servo motor; a vertical guide rail is provided on the frame, and the slide is slidably connected to the vertical guide rail;

[0018] The riveting mechanism also includes a speed reducer, and the servo motor is connected to the rotating spindle through the speed reducer.

[0019] The servo motor drives the rotation, and the transmission is achieved layer by layer through the reducer and the rotating spindle, ultimately allowing the riveting head to rotate for processing. The reducer adjusts the reduction ratio to convert the high speed of the servo motor to a low speed output, ensuring the riveting mechanism achieves a suitable rotational speed. This speed meets the requirements for sufficient plastic deformation in rivet forming while avoiding problems such as overheating of the rivet, material burning, or structural damage caused by excessive speed, thus ensuring stable and reliable riveting quality. Furthermore, the slide can be connected to a power unit to achieve automatic lifting of the riveting mechanism, eliminating the need for manual height setting and preventing inconsistent processing results.

[0020] Preferably, the riveting mechanism is provided with a sensing component, which includes a pressure sensor, a displacement sensor and a temperature sensor;

[0021] The pressure sensor is located inside the riveting head, the displacement sensor is located on the slide, and the temperature sensor is used to detect the temperature of the servo motor and the reducer.

[0022] By integrating pressure, displacement, and temperature sensors into the riveting mechanism, multi-dimensional and precise control and monitoring of the riveting process are achieved. The pressure sensor is embedded inside the riveting head to directly measure the axial pressure during riveting, ensuring that the pressure value matches the material characteristics, avoiding incomplete riveting or workpiece damage, and guaranteeing connection strength. The displacement sensor is mounted on the slide table to monitor the feed depth and position of the riveting head in real time, accurately controlling the rivet pressing stroke and ensuring consistent riveting height. The temperature sensor monitors the operating temperature of the servo motor and reducer, preventing malfunctions caused by overheating and extending the life of core components.

[0023] Preferably, the riveting mechanism further includes an absolute encoder, which is connected to the servo motor.

[0024] Among them, the absolute encoder can provide real-time and accurate feedback on the rotation angle and position of the servo motor, ensuring that the rotation angle of the riveting head strictly conforms to the set value, avoiding poor workpiece forming or workpiece damage due to angle deviation, and improving riveting accuracy.

[0025] Preferably, the device further includes an automatic lubrication mechanism, which includes a distributor and an oil delivery device. The oil delivery device is connected to the distributor, and the distributor is fixed to the bottom of the second platform and located near the lifting cylinder.

[0026] The distributor's structural design enables it to distribute lubricating oil according to a preset ratio. The oil delivery device continuously supplies lubricating oil to the distributor, forming a stable oil supply cycle. Through the coordinated operation of the distributor and the oil delivery device, precise and timed lubrication of the lifting cylinder and surrounding moving parts can be achieved.

[0027] Preferably, the device further includes a waste collection mechanism disposed below the alternating feeding mechanism for collecting debris generated during the riveting process by means of negative pressure.

[0028] During the processing, when the riveting structure rotates and applies pressure to shape the rivet head, excess material is sheared or torn, generating debris. Furthermore, when the rivet or workpiece undergoes plastic flow under high pressure, the surface material may also fracture brittlely due to localized stress concentration, forming tiny metal particles. The waste collection mechanism effectively handles these debris particles. Firstly, it reduces the risk of debris clogging the first and second guide slide components. Secondly, it prevents the lifting cylinder from jamming, thus maintaining the stability of the alternating feeding mechanism.

[0029] As can be seen from the technical solutions described above, this application provides a servo riveting device with an alternating platform. This device includes an alternating feeding mechanism, which comprises a first platform assembly and a second platform assembly. The first platform assembly includes a first platform, a lifting cylinder connected to the bottom of the first platform, and a first guide slide assembly connected to the bottom of the lifting cylinder. By directly connecting the lifting cylinder to the bottom of the first platform, redundant transition structures that may exist in traditional designs, such as additional support frames or complex linkage mechanisms, are eliminated, simplifying the mechanical structure. The first guide slide assembly at the bottom of the lifting cylinder ensures that the platform movement is always guided and constrained, guaranteeing the accuracy of the horizontal displacement direction of the first platform.

[0030] The second platform assembly includes a second platform, a second guide slide assembly connected to the bottom of the second platform, and a base disposed at the bottom of the second guide slide assembly. The first guide slide assembly is disposed below the base, the lifting cylinder is located outside the base, and the first platform is located above the second guide slide assembly. Existing multi-platform loading mechanisms suffer from loose structures and redundant parts. Redundant structures also occupy more space and reduce the layout flexibility of other structures within the equipment. However, this application achieves multifaceted performance improvements through a highly integrated structural layout, allowing the first platform to be directly located above the second guide slide assembly to form a compact stacked structure, reducing the overall size and optimizing space utilization.

[0045] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0046] In the description of this utility model, the terms "upper", "lower", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not require that this utility model must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] In traditional riveting equipment, manual labor is the primary method of loading, with some equipment employing simple mechanical assistance. Specifically, operators manually place the workpiece into the fixture, then position the rivet on a vibratory feeder or a dedicated feeder, and the loading is completed by the movement of the equipment. Some existing equipment also uses a multi-platform loading mechanism to achieve alternating loading, thus enabling continuous operation. While this design can speed up loading, it is bulky, making it difficult to adjust the layout of other structures within the equipment and hindering further improvements. It also occupies more space during transportation, increasing logistics costs. Furthermore, due to its large size and uneven weight distribution, it is less flexible and convenient than smaller, more compact mechanisms when fixed in place, potentially requiring additional reinforcement or adjustments to the working hours, thus affecting installation efficiency. Therefore, this mechanism brings inconvenience in terms of transportation, installation, and use.

[0048] To this end, the applicant has developed a new type of servo riveting equipment with an alternating platform. By improving the feeding structure and adopting a compact alternating feeding mechanism, the equipment effectively frees up internal space, thereby reducing the overall size and significantly improving space utilization.

[0049] Example 1

[0050] The following is combined Figure 1 and 2This application introduces a servo riveting device with alternating platforms. The device includes an alternating feeding mechanism, which may include a first platform assembly 1 and a second platform assembly 2. The first platform assembly 1 includes a first platform 11, a lifting cylinder 12 connected to the bottom of the first platform 11, and a first guide slide assembly connected to the bottom of the lifting cylinder 12. The second platform assembly 2 includes a second platform 21, a second guide slide assembly connected to the bottom of the second platform 21, and a base 24 disposed at the bottom of the second guide slide assembly. The first guide slide assembly is disposed below the base 24, the lifting cylinder 12 is located outside the base 24, and the first platform 11 is located above the second guide slide assembly.

[0051] See Figure 1 As shown, the first guide slide assembly includes a sliding plate 13, a first slider 14 and a guide rail 15. The top of the guide rail 15 is slidably connected to the first slider 14, and the top of the first slider 14 is fixed to the sliding plate 13. The sliding plate 13 is connected to the bottom of the lifting cylinder 12.

[0052] The second guide slide assembly includes a second slider 22 and a slide rail 23. The slide rail 23 is mounted on the top of the base 24, and the top of the slide rail 23 is slidably connected to the second slider 22. The second slider 22 is connected to the bottom of the second platform 21.

[0053] See Figure 5 and 6 As shown, the equipment also includes a frame 5 and a riveting mechanism 6. The riveting mechanism 6 is slidably connected to the frame 5, and the alternating feeding mechanism is installed on the frame 5 and located below the riveting mechanism 6.

[0054] The riveting mechanism 6 includes a riveting head 61, a rotating spindle 62 fixed on the top of the riveting head 61, a servo motor 64 connected above the rotating spindle 62, and a slide table 65 fixed on the servo motor 64; a vertical guide rail 51 is provided on the frame 5, and the slide table 65 is slidably connected to the vertical guide rail 51.

[0055] The riveting mechanism 6 also includes a reducer 63, and the servo motor 64 is connected to the rotating spindle 62 through the reducer 63.

[0056] Specifically, workpiece fixtures can be installed on the first platform 11 and the second platform 21 to fix the workpieces. Both platforms can be used for manual workpiece clamping or auxiliary equipment such as robotic arms for workpiece installation. The drive end of the lifting cylinder 12 is fixed to the bottom of the first platform 11. Optionally, the drive end of the lifting cylinder 12 can also be fixed to the sliding plate 13. The bottom (or drive end) of the lifting cylinder 12 is fixed to the sliding plate 13, and the bottom of the sliding plate 13 is fixed to the first slider 14. Furthermore, the lifting cylinders 12 can be symmetrically arranged on both sides of the sliding plate 13 and on both sides of the base 24 for easy installation, debugging, and daily maintenance. The base 24 can adopt a frame design with a positioning slot on the top for mounting the slide rail 23, which can reduce weight, material consumption, and manufacturing costs. The guide rail 15 is arranged parallel to the slide rail 23, so that the displacement paths of the first platform 11 and the second platform 21 are the same, reducing the space required in actual use and enabling precise material loading. The second platform 21 abuts against the second slider 22 and adopts a non-fixed connection, so it can be separated from the second slider 22 and its position can be flexibly adjusted.

[0057] A servo motor 64 is mounted on top of the frame 5 for rotational drive, and transmits power layer by layer from top to bottom through a reducer 63 and a rotating spindle 62, ultimately enabling the riveting head 61 to rotate for processing. A slide table 65 is mounted on the side of the servo motor 64 near the frame 5, with four sliding members arranged around its perimeter, slidably connected to the vertical guide rail 51. Therefore, the riveting mechanism 6, slidably connected to the frame 5, allows it to move flexibly along the vertical guide rail 51, thus enabling pressure processing of the workpiece, achieving high-precision, high-strength riveting operations, and improving the overall performance and reliability of the equipment.

[0058] It is evident that this equipment simplifies the mechanical structure and highly integrates the multi-platform loading structure to form a compact alternating loading mechanism. This reduces the overall size of the loading structure and optimizes space utilization, increasing the usable space inside the equipment and providing a spatial basis for further optimization of the internal structure. At the same time, with the help of the alternating loading mechanism and the alternating operation mode of the two platforms, the idle time of the equipment is greatly reduced. Furthermore, it can be used with quick-change workpiece fixtures to effectively shorten the product changeover time and significantly improve production efficiency.

[0059] Example 2

[0060] See Figure 2 As shown, based on the above embodiment 1, this embodiment provides another servo riveting device with alternating platforms. The base 24 is provided with a synchronization mechanism 3. The synchronization mechanism 3 includes a synchronous motor 31, a rotating shaft 32 and a synchronous belt 33. The synchronous motor 31 and the rotating shaft 32 are both mounted on the base 24. The synchronous belt 33 is wound around the drive end of the synchronous motor 31 and the rotating shaft 32. The synchronous belt 33 connects the first guide slide assembly and the second platform 21.

[0061] See Figure 3 As shown, a lifting cylinder 4 is also provided on the base 24, and the driving end of the lifting cylinder 4 abuts against the bottom of the second platform 21.

[0062] Furthermore, the riveting mechanism 6 is equipped with sensing components, including a pressure sensor, a displacement sensor, and a temperature sensor.

[0063] The pressure sensor is located inside the riveting head 61, the displacement sensor is located on the slide table 65, and the temperature sensor is used to detect the temperature of the servo motor 64 and the reducer 63.

[0064] Furthermore, the riveting mechanism 6 also includes an absolute encoder, which is connected to the servo motor 64.

[0065] Specifically, the synchronous motor 31 and the rotating shaft 32 are parallel to the first platform 11 and the second platform 21, and are both installed on the left side of the base 24. The synchronous motor 31 and the rotating shaft 32 tension the toothed synchronous belt 33. The second platform 21 and the sliding plate 13 are both provided with connectors with toothed connecting surfaces. The connectors are connected to the upper and lower sides of the synchronous belt 33 respectively, so as to achieve the effect of synchronizing and moving the two in opposite directions, thereby replacing the manual movement of the first platform 11 and the second platform 21, and making the alternating feeding mechanism intelligent.

[0066] To optimize the processing, the lifting cylinder 4 is fixed inside the base 24, and its top drive end is provided with a mating boss. The bottom of the second platform 21 has a mating groove. By matching the mating boss with the mating groove, the lifting cylinder 4 can stably lift the second platform 21. During the workpiece riveting process, it can cooperate with the riveting mechanism 6 to compress the workpiece, increase the tightness of the connection between the workpieces, and thus improve the riveting quality. Understandably, the lifting cylinder 12 can make the first platform 11 cooperate with the riveting mechanism 6 to apply pressure, thereby optimizing the riveting effect.

[0067] For high-precision control, pressure, displacement, and temperature sensors are integrated into the riveting mechanism 6, enabling multi-dimensional precise control and monitoring of the riveting process. The pressure sensor is embedded inside the riveting head 61, directly measuring the axial pressure during riveting to ensure the pressure value matches material characteristics, preventing incomplete riveting or workpiece damage, and guaranteeing connection strength. The displacement sensor is mounted on the slide table 65, monitoring the feed depth and position of the riveting head in real time, precisely controlling the rivet pressing stroke, and ensuring consistent riveting height. The temperature sensor can be a patch sensor or an infrared sensor, fixed to the servo motor 64 or mounted on a bracket on the riveting mechanism 6, to monitor the operating temperature of the servo motor 64 and the reducer 63, preventing overheating damage and extending the lifespan of core components. Thus, these three sensors work together to form a closed-loop monitoring system, providing real-time data feedback to the control system. This allows for dynamic adjustment of parameters such as pressure and speed to adapt to different materials and process requirements, improving riveting consistency and automation levels. Simultaneously, it provides early warning of potential failures, reducing downtime and significantly improving production efficiency and equipment reliability.

[0068] To further improve control precision, the device also utilizes an absolute encoder to provide real-time, precise feedback on the rotation angle and position of the servo motor 64. Specifically, the absolute encoder is coaxially connected to the servo motor 64 and can be positioned between the servo motor 64 and the reducer 63. It is connected to the servo motor 64 via protocol requirements, including clock lines (CLK), data lines (DATA), and enable lines. For example, the Bi SS protocol requires connection to CLK, DATA, and STB lines, transmitting position data through differential signals. This ensures that the rotation angle of the riveting head 61 strictly conforms to the set value, preventing poor workpiece forming or damage due to angular deviations and improving riveting accuracy. The absolute position information provided by the encoder helps the control system achieve high-precision motion control, allowing the riveting mechanism 6 to stop or switch actions at specific angles (such as step-by-step riveting), meeting the needs of multi-step riveting processes, and is particularly suitable for the precise machining of complex workpiece structures.

[0069] Example 3

[0070] See Figure 4 As shown, this embodiment improves upon embodiment 2 and provides a servo riveting device with alternating platforms. The device also includes an automatic lubrication mechanism, which includes a distributor 7 and an oil feeder. The oil feeder is connected to the distributor 7. The distributor 7 is fixed to the bottom of the second platform 21 and is located near the lifting cylinder 4.

[0071] Furthermore, the equipment also includes a waste collection mechanism located below the alternating feeding mechanism, which is used to collect debris generated during the riveting process by means of negative pressure.

[0072] Specifically, the oil feeder can be installed on the frame 5 according to actual needs, and the distributor 7 can be installed on the bottom of the second platform 21 and the sliding plate 13. The distributor 7 distributes lubricating oil according to a preset ratio to lubricate the toothed connection surfaces of the piston rod of the lifting cylinder 4 and the connecting parts on the sliding plate 13. The oil feeder continuously delivers lubricating oil to the distributor 7, forming a stable oil supply cycle. Through the coordinated operation of the distributor 7 and the oil feeder, precise and timed lubrication of the connecting parts on the lifting cylinder 4 and the sliding plate 13 can be achieved. At the same time, the synchronous belt 33 carries lubricating oil to lubricate the toothed connection surfaces of the transmission components at the bottom of the second platform 21, thereby reducing transmission jamming.

[0073] During processing, when the riveting structure rotates and applies pressure to shape the rivet head, excess material is sheared or torn, generating debris. Furthermore, when the rivet or workpiece undergoes plastic flow under high pressure, the surface material may also fracture brittlely due to localized stress concentration, forming tiny metal particles. The waste collection mechanism effectively handles these debris particles. It utilizes a fan and connected pipes, along with a collection box, to absorb and collect the debris. This reduces the risk of blockage in the first and second guide components due to debris and prevents jamming of the lifting cylinder 12, thus maintaining the stability of the alternating feeding mechanism.

[0074] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
