Description

Technical Field

[0001] The utility model relates to the technical field of riveting equipment, in particular to a riveting assembly and a riveting machine. Background Art

[0002] At present, when using a riveting machine to rivet a workpiece, the riveting assembly in the riveting machine and the fixture for transporting the workpiece usually operate in a one-to-one matching manner. The working process is as follows: First, after the fixture receives the workpiece from the loading position, it transports the workpiece to the riveting assembly for riveting. After the workpiece is riveted, the fixture transports the workpiece to the unloading position for unloading, and then the next round of workpiece riveting is carried out. In the above working process, when the fixture transports the workpiece for loading and unloading, the waiting time interval of the riveting assembly for riveting is very long, resulting in low overall production efficiency and wasting a large amount of processing time. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a riveting assembly and a riveting machine, aiming to solve the technical problem of low production efficiency when using the riveting assembly to rivet a workpiece at present.

[0004] To achieve the above object, the utility model provides a riveting assembly, comprising:

[0005] A riveting mechanism, with a riveting position arranged below the riveting mechanism;

[0006] A first fixture, which is used to receive the workpiece at the first loading position;

[0007] A second fixture, which is used to receive the workpiece at the second loading position;

[0008] A slide rail, with the first fixture arranged at one end of the slide rail and the second fixture arranged at the other end of the slide rail. The first fixture is configured to be able to move along the slide rail between the first loading position and the riveting position, and the second fixture is configured to be able to move along the slide rail between the second loading position and the riveting position;

[0009] A first lifting mechanism, which is arranged at the riveting position and is used to lift the first fixture or the second fixture to make the first fixture or the second fixture in an inclined state;

[0010] Wherein, when the first fixture moves from the riveting position towards the first loading position, the second fixture moves from the second loading position towards the riveting position;

[0011] Or, when the second fixture moves from the riveting position towards the second loading position, the first fixture moves from the first loading position towards the riveting position.

[0012] Specifically, in this embodiment, two feeding fixtures are correspondingly arranged for one riveting mechanism in the riveting assembly, namely the first fixture and the second fixture, and the first fixture and the second fixture alternately transport workpieces to the riveting mechanism. When the riveting assembly works, first, the first fixture will receive the workpiece to be processed at the first feeding position, and then the first fixture will move along the slide rail to transport the workpiece to be processed from the first feeding position to the riveting position. When the first fixture reaches the riveting position, the riveting mechanism will perform riveting on the workpiece on the first fixture. After the riveting of the workpiece on the first fixture is completed, the first lifting mechanism will lift the first fixture upward, and the first fixture will change from a horizontal state to an inclined state (it should be noted that in order to ensure that the first fixture can stably receive and convey the workpiece, the initial state of the first fixture is horizontal, and only after the first fixture is lifted by the first lifting mechanism, the first fixture will change to an inclined state). At this time, the workpiece that has been riveted on the first fixture will slide off the first fixture under the action of its own gravity, thus completing the collection of the riveted workpiece. While the first fixture is discharging, the second fixture will receive the workpiece to be processed at the second feeding position. Ideally, when the first fixture finishes discharging, the second fixture finishes loading.

[0013] Further, after the first fixture finishes discharging, the first fixture starts to move along the slide rail from the riveting position towards the first feeding position. At the same time, the second fixture starts to move along the slide rail from the second feeding position towards the riveting position. When the second fixture reaches the riveting position, the riveting mechanism will perform riveting on the workpiece on the second fixture. After the riveting of the workpiece on the second fixture is completed, the first lifting mechanism will lift the second fixture upward, and the second fixture will change from a horizontal state to an inclined state. At this time, the workpiece that has been riveted on the second fixture will slide off the second fixture under the action of its own gravity, thus completing the collection of the riveted workpiece. While the second fixture is discharging, the first fixture will receive a new workpiece to be processed at the first feeding position, and so on for cyclic processing to achieve batch production of workpieces.

[0014] The riveting assembly provided in this embodiment transports workpieces to the riveting mechanism alternately through the first fixture and the second fixture, effectively shortening the time interval for the riveting mechanism to wait for the riveted workpiece, thereby improving the production and processing efficiency and saving the time cost of production and processing. Moreover, the riveting assembly provided in this embodiment adopts the method of "riveting while discharging", which is conducive to quickly collecting workpieces and avoiding accidents during workpiece transportation (exemplarily, for example, avoiding the workpiece falling from the fixture during transportation, resulting in workpiece damage). In addition, the overall volume of the riveting assembly provided in this embodiment is small, which is conducive to saving floor space.

[0015] In some embodiments, the first fixture includes a first workpiece supporting table and a first slideway. The first workpiece supporting table and the first slideway are hinged together. The first workpiece supporting table is used for supporting a workpiece, and the first slideway is used for transferring the workpiece.

[0016] The second fixture includes a second workpiece supporting table and a second slideway. The second workpiece supporting table and the second slideway are hinged together. The second workpiece supporting table is used for supporting a workpiece, and the second slideway is used for transferring the workpiece.

[0017] Wherein, the first lifting mechanism is used for lifting the first workpiece supporting table or the second workpiece supporting table to make the first workpiece supporting table or the second workpiece supporting table in an inclined state.

[0018] Specifically, in this embodiment, the first workpiece supporting table realizes the transportation of the workpiece between the first loading position and the riveting position, and the second workpiece supporting table realizes the transportation of the workpiece between the second loading position and the riveting position. When the first lifting mechanism lifts the first workpiece supporting table, the first workpiece supporting table will drive the first slideway to tilt at a larger angle, so as to facilitate the workpiece on the first workpiece supporting table to slide down smoothly along the first slideway to complete the unloading of the workpiece. When the first lifting mechanism lifts the second workpiece supporting table, the second workpiece supporting table will drive the second slideway to tilt at a larger angle, so as to facilitate the workpiece on the second workpiece supporting table to slide down smoothly along the second slideway to complete the unloading of the workpiece.

[0019] In some embodiments, at the riveting position, a blanking position is provided at one end of the first slideway away from the first workpiece supporting table, and the blanking position is used for collecting the processed workpiece.

[0020] Specifically, in this embodiment, providing a blanking position at the riveting position is beneficial for the riveting assembly to "rivet and unload materials simultaneously", so as to realize the rapid collection of the processed workpiece, avoid accidents such as bumping and dropping of the processed workpiece during transportation, and reduce the rejection rate of the processed workpiece.

[0021] In some embodiments, the inclination angle α1 of the first workpiece supporting table satisfies: 15° ≤ α1 ≤ 45°, and the inclination angle α2 of the second workpiece supporting table satisfies: 15° ≤ α2 ≤ 45°.

[0022] Specifically, in this embodiment, after the first material receiving platform or the second material receiving platform is lifted by the first lifting mechanism, the inclination angle of the first material receiving platform or the second material receiving platform is set within the above angle range. On the one hand, it prevents the inclination angle of the first material receiving platform or the second material receiving platform from being too small (exemplarily, for example, the inclination angle of the first material receiving platform or the second material receiving platform is 3°, 5°, 10°, etc.), which may cause the workpiece to not slide down smoothly from the first material receiving platform or the second material receiving platform, affecting the collection progress of the workpiece and delaying the collection time of the workpiece. On the other hand, it prevents the inclination angle of the first material receiving platform or the second material receiving platform from being too large (exemplarily, for example, the inclination angle of the first material receiving platform or the second material receiving platform is 55°, 60°, 70°, etc.), which may cause the first material receiving platform or the second material receiving platform to turn over and capsize, so that after the first lifting mechanism cancels the lifting force on the first material receiving platform or the second material receiving platform, the first material receiving platform or the second material receiving platform cannot self-reset, affecting the normal processing process of the riveting and pressing assembly and increasing the maintenance cost of the first material receiving platform or the second material receiving platform.

[0023] In some embodiments, the first slideway is provided with a first oblong hole, and a first pin is inserted through the first oblong hole. The first slideway can move along with the first material receiving platform to increase the inclination angle of the first slideway.

[0024] The second slideway is provided with a second oblong hole, and a second pin is inserted through the second oblong hole. The second slideway can move along with the second material receiving platform to increase the inclination angle of the second slideway.

[0025] Specifically, in this embodiment, the first slideway adopts the connection method of mutual cooperation between the first pin and the first oblong hole to realize the function of independently adjusting the inclination angle when the first slideway moves along with the first material receiving platform. The second slideway adopts the connection method of mutual cooperation between the second pin and the second oblong hole to realize the function of independently adjusting the inclination angle when the second slideway moves along with the second material receiving platform.

[0026] In some embodiments, a second lifting mechanism is arranged at the riveting position. The second lifting mechanism is used to lift the first slideway or the second slideway to increase the inclination angle of the first slideway or the second slideway.

[0027] Specifically, in this embodiment, through the second lifting mechanism, the inclination angle of the first slideway or the second slideway can be adjusted separately, so that the workpiece can slide down smoothly along the first slideway or the second slideway, thus facilitating the unloading and collection of the workpiece.

[0028] In some embodiments, the slide rail is a linear track, and the distance L1 that the first jig moves along the slide rail from the first loading position to the riveting position and the distance L2 that the second jig moves along the slide rail from the second loading position to the riveting position satisfy: L1 = L2.

[0029] Specifically, in this embodiment, the first jig and the second jig have the same moving distance on the slide rail, so that the first jig and the second jig can be set to have the same sliding speed, so that the first jig slides from the first loading position to the riveting position and the second jig slides from the second loading position to the riveting position have the same sliding time. With the above settings, it is beneficial to adjust the riveting mechanism to the same rivet frequency, thereby facilitating the improvement of the production rhythm of the riveting mechanism.

[0030] In some embodiments, the first jig is driven by a first cylinder, and the first cylinder drives the first jig to move along the slide rail between the first loading position and the riveting position; the second jig is driven by a second cylinder, and the second cylinder drives the second jig to move along the slide rail between the second loading position and the riveting position.

[0031] Specifically, in this embodiment, by driving the first jig by the first cylinder and driving the second jig by the second cylinder, the movement stability of the first jig and the second jig can be ensured, and further, the workpiece can be stably conveyed between the loading position and the riveting position, effectively preventing the workpiece from being jolted, bumped, dropped and damaged during the transportation process. In addition, the first cylinder and the second cylinder are convenient for installation and maintenance, which is beneficial to reducing production costs.

[0032] In some embodiments, the first jig is driven by a first motor, and the first motor drives the first jig to move along the slide rail between the first loading position and the riveting position; the second jig is driven by a second motor, and the second motor drives the second jig to move along the slide rail between the second loading position and the riveting position.

[0033] Specifically, in this embodiment, by driving the first jig by the first motor and driving the second jig by the second motor, on the one hand, it is beneficial to ensure the position accuracy of the first jig and the second jig, so as to ensure that the first jig can accurately move from the first loading position to the riveting position and the second jig can accurately move from the second loading position to the riveting position, realizing the precise processing of the workpiece by the riveting mechanism. On the other hand, it is beneficial to ensure the movement stability of the first jig and the second jig, so as to ensure that the workpiece can be stably conveyed between the loading position and the riveting position, effectively preventing the workpiece from being jolted, bumped, dropped and damaged during the transportation process.

[0034] Correspondingly, the present invention also proposes a riveting machine, including:

[0035] The riveting assembly described in any of the above embodiments;

[0036] The first feeding mechanism is arranged at the first feeding position of the riveting assembly and is used to feed the first jig of the riveting assembly;

[0037] The second feeding mechanism is arranged at the second feeding position of the riveting assembly and is used to feed the second jig of the riveting assembly.

[0038] Specifically, in this embodiment, the first feeding mechanism and the second feeding mechanism are adopted to realize the feeding of workpieces, which is beneficial to liberating manpower, improving production efficiency and realizing automated production. Description of the Drawings

[0066] Currently, when using a riveting press to rivet a workpiece, the riveting assembly in the riveting press and the fixture for transporting the workpiece usually operate in a one-to-one matching manner. The working process is as follows: First, after the fixture receives the workpiece from the loading position, it transports the workpiece to the riveting assembly for riveting. After the workpiece is riveted, the fixture transports the workpiece to the unloading position for unloading, and then proceeds to the next round of workpiece riveting. During the above working process, when the fixture transports the workpiece for loading and unloading, the time interval for the riveting assembly to wait for riveting is very long, resulting in low overall production efficiency and wasting a large amount of processing time.

[0067] Based on this, in order to solve the technical problem of low production efficiency when using a riveting assembly to rivet a workpiece currently, referring to Figures 1 to 5, an embodiment of the present application provides a riveting assembly, which includes a riveting mechanism 100, a first fixture 200, a second fixture 300, a slide rail 400, and a first lifting mechanism 500. There is a riveting position 800 below the riveting mechanism 100, and a first loading position 900 is provided at the first fixture 200. The first fixture 200 is used to receive the workpiece at the first loading position 900. A second loading position 1000 is provided at the second fixture 300, and the second fixture 300 is used to receive the workpiece at the second loading position 1000. The first fixture 200 is arranged at one end of the slide rail 400, and the second fixture 300 is arranged at the other end of the slide rail 400. The first fixture 200 is configured to be able to move along the slide rail 400 between the first loading position 900 and the riveting position 800, and the second fixture 300 is configured to be able to move along the slide rail 400 between the second loading position 1000 and the riveting position 800. The first lifting mechanism 500 is arranged at the riveting position 800, and the first lifting mechanism 500 is used to lift the first fixture 200 or the second fixture 300 to make the first fixture 200 or the second fixture 300 in an inclined state. Among them, when the first fixture 200 moves from the riveting position 800 towards the first loading position 900, the second fixture 300 moves from the second loading position 1000 towards the riveting position 800; or, when the second fixture 300 moves from the riveting position 800 towards the second loading position 1000, the first fixture 200 moves from the first loading position 900 towards the riveting position 800. Exemplarily, for example, the above riveting assembly can be applied to rivet the headrest support of a children's seat.

[0068] Specifically, in this embodiment, two feeding fixtures are correspondingly provided for one riveting mechanism 100 in the riveting assembly, namely the first fixture 200 and the second fixture 300. The first fixture 200 and the second fixture 300 alternately transport workpieces to the riveting mechanism 100. When the riveting assembly works, first, the first fixture 200 will receive the workpiece to be processed at the first feeding position 900, and then the first fixture 200 will move along the slide rail 400 to transport the workpiece to be processed from the first feeding position 900 to the riveting position 800. When the first fixture 200 reaches the riveting position 800, the riveting mechanism 100 will perform riveting on the workpiece on the first fixture 200. After the riveting of the workpiece on the first fixture 200 is completed, the first lifting mechanism 500 will lift the first fixture 200 upward, and the first fixture 200 will change from a horizontal state to an inclined state (it should be noted that in order to ensure that the first fixture 200 can smoothly receive and transport the workpiece, the initial state of the first fixture 200 is a horizontal state, and only after the first fixture 200 is lifted by the first lifting mechanism 500, the first fixture 200 will change to an inclined state). At this time, the riveted workpiece on the first fixture 200 will slide off the first fixture 200 under the action of its own gravity, thus completing the collection of the riveted workpiece. While the first fixture 200 is discharging the workpiece, the second fixture 300 will receive the workpiece to be processed at the second feeding position 1000. Ideally, when the first fixture 200 finishes discharging the workpiece, the second fixture 300 finishes loading the workpiece.

[0069] Furthermore, after the first fixture 200 finishes discharging the workpiece, the first fixture 200 starts to move along the slide rail 400 from the riveting position 800 towards the first feeding position 900. At the same time, the second fixture 300 starts to move along the slide rail 400 from the second feeding position 1000 towards the riveting position 800. When the second fixture 300 reaches the riveting position 800, the riveting mechanism 100 will perform riveting on the workpiece on the second fixture 300. After the riveting of the workpiece on the second fixture 300 is completed, the first lifting mechanism 500 will lift the second fixture 300 upward, and the second fixture 300 will change from a horizontal state to an inclined state. At this time, the riveted workpiece on the second fixture 300 will slide off the second fixture 300 under the action of its own gravity, thus completing the collection of the riveted workpiece. While the second fixture 300 is discharging the workpiece, the first fixture 200 will receive a new workpiece to be processed at the first feeding position 900. In this way, the processing is repeated in a cycle to achieve mass production of workpieces.

[0070] The riveting assembly provided in this embodiment transmits the workpiece to the riveting mechanism 100 in an alternating manner through the first fixture 200 and the second fixture 300, which effectively shortens the time interval for the riveting mechanism 100 to wait for the riveted workpiece, thereby improving the production and processing efficiency and saving the time cost of production and processing. Moreover, the riveting assembly provided in this embodiment adopts the method of "riveting while unloading", which is conducive to the rapid collection of workpieces and avoids accidents during transportation of workpieces (for example, to avoid the workpiece falling from the fixture during transportation, causing damage to the workpiece). In addition, the overall volume of the riveting assembly provided in this embodiment is small, which is conducive to saving floor space.

[0071] Furthermore, when riveting the workpiece, the first lifting mechanism 500 will also support the first jig 200 or the second jig 300, provide support for the first jig 200 or the second jig 300, and absorb excess impact force to ensure that the riveting mechanism 100, the first jig 200 and the second jig 300 are not subjected to reaction force and thus have their service life reduced.

[0072] Furthermore, in some embodiments, the first lifting mechanism 500 may be a lifting cylinder.

[0073] In some embodiments, reference Figures 1 to 3 The first fixture 200 includes a first material receiving platform 210 and a first slide 220, the first material receiving platform 210 and the first slide 220 are hinged together, the first material receiving platform 210 is used to receive the workpiece, and the first slide 220 is used to transfer the workpiece. The second fixture 300 includes a second material receiving platform 310 and a second slide 320, the second material receiving platform 310 and the second slide 320 are hinged together, the second material receiving platform 310 is used to receive the workpiece, and the second slide 320 is used to transfer the workpiece. Among them, the first lifting mechanism 500 is used to lift the first material receiving platform 210 or the second material receiving platform 310, so that the first material receiving platform 210 or the second material receiving platform 310 is in an inclined state.

[0074] Specifically, in this embodiment, when the workpiece rivet processing is performed, the first material platform 210 realizes the transportation of the workpiece between the first loading position 900 and the riveting position 800. When the workpiece is unloaded, since the first material platform 210 and the first slide 220 are connected in a hinged flexible manner, when the first material platform 210 is lifted, the first material platform 210 will drive the first slide 220 to tilt at a larger angle, thereby facilitating the unloading of the workpiece on the first material platform 210 along the first slide 220 and preventing the workpiece from being stuck on the first slide 220.

[0075] Similarly, when processing the workpiece rivets, the second material supporting table 310 realizes the transportation of the workpiece between the second loading position 1000 and the riveting position 800. When unloading the workpiece, since the second material supporting table 310 and the second slideway 320 adopt a hinged flexible connection method, when the second material supporting table 310 is lifted, the second material supporting table 310 will drive the second slideway 320 to tilt at a larger angle, so as to facilitate the workpiece on the second material supporting table 310 to complete unloading along the second slideway 320 and prevent the workpiece from getting stuck on the second slideway 320.

[0076] Further, in some embodiments, the first material supporting table 210 and the first slideway 220 can be hinged together through a hinge, and the second material supporting table 310 and the second slideway 320 can be hinged together through a hinge.

[0077] In some embodiments, referring to Figure 2 and Figure 3 , at the riveting position 800, a blanking position 1100 is provided at one end of the first slideway 220 away from the first material supporting table 210, and the blanking position 1100 is used to collect the processed workpieces. After the workpiece rivets on the first material supporting table 210 are processed, the processed workpieces will slide along the first slideway 220 to the blanking position 1100. It should be noted that at the riveting position 800, the first fixture 200 and the second fixture 300 share a blanking position 1100 to realize unloading, that is, after the workpiece rivets on the second material supporting table 310 are processed, the processed workpieces will slide along the second slideway 320 to the blanking position 1100.

[0078] Specifically, in this embodiment, a blanking position 1100 is provided at the riveting position 800, which is conducive to the riveting assembly to "rivet while unloading", so as to realize the rapid collection of the processed workpieces, avoid accidents such as bumps and drops of the processed workpieces during transportation, and reduce the rejection rate of the processed workpieces.

[0079] Further, in some embodiments, a material box can be provided at the blanking position 1100, and the riveted workpieces can be received and collected through the material box.

[0080] In some embodiments, referring to Figure 3 , the inclination angle α1 of the first material supporting table 210 satisfies: 15°≤α1≤45°, and the inclination angle α2 of the second material supporting table 310 satisfies: 15°≤α2≤45°. Exemplarily, for example, the value of α1 can be 15°, 20°, 30°, 35°, 40°, 45°, etc. The value of α2 can be 15°, 20°, 30°, 35°, 40°, 45°, etc.

[0081] Specifically, in this embodiment, after the first material receiving platform 210 or the second material receiving platform 310 is lifted by the first lifting mechanism 500, the inclination angle of the first material receiving platform 210 or the second material receiving platform 310 is set within the above angle range. On the one hand, it prevents the inclination angle of the first material receiving platform 210 or the second material receiving platform 310 from being too small (exemplarily, for example, the inclination angle of the first material receiving platform 210 or the second material receiving platform 310 is 3°, 5°, 10°, etc.), which may cause the workpiece to not slide down smoothly from the first material receiving platform 210 or the second material receiving platform 310, affecting the workpiece collection progress and delaying the workpiece collection time. On the other hand, it prevents the inclination angle of the first material receiving platform 210 or the second material receiving platform 310 from being too large (exemplarily, for example, the inclination angle of the first material receiving platform 210 or the second material receiving platform 310 is 55°, 60°, 70°, etc.), which may cause the first material receiving platform 210 or the second material receiving platform 310 to tip over. After the first lifting mechanism 500 cancels the lifting force on the first material receiving platform 210 or the second material receiving platform 310, the first material receiving platform 210 or the second material receiving platform 310 cannot self-reset, affecting the normal processing process of the riveting and pressing assembly and increasing the maintenance cost of the first material receiving platform 210 or the second material receiving platform 310.

[0082] In some embodiments, referring to Figures 1 to 5 , the first slideway 220 is provided with a first long circular hole 221, and a first pin 222 is inserted into the first long circular hole 221. The first slideway 220 can move with the first material receiving platform 210 to increase the inclination angle of the first slideway 220. The second slideway 320 is provided with a second long circular hole 321, and a second pin 322 is inserted into the second long circular hole 321. The second slideway 320 can move with the second material receiving platform 310 to increase the inclination angle of the second slideway 320.

[0083] Specifically, in this embodiment, the first slideway 220 adopts a connection method in which the first pin 222 and the first long circular hole 221 cooperate with each other to realize the function of automatically adjusting the inclination angle when the first slideway 220 moves with the first material receiving platform 210. The second slideway 320 adopts a connection method in which the second pin 322 and the second long circular hole 321 cooperate with each other to realize the function of automatically adjusting the inclination angle when the second slideway 320 moves with the second material receiving platform 310.

[0084] When the first lifting mechanism 500 lifts the first material receiving platform 210, the first material receiving platform 210 will tilt, and at the same time, the first material receiving platform 210 will drive the first slideway 220 to move. At this time, the first pin 222 will slide in the first long circular hole 221 to improve the flexibility of the first slideway 220 during movement, facilitating the first slideway 220 to tilt at a larger angle, so as to ensure that the workpiece can slide smoothly along the first slideway 220 to the blanking position 1100.

[0085] Similarly, when the first lifting mechanism 500 lifts the second material supporting table 310, the second material supporting table 310 will tilt, and at the same time, the second material supporting table 310 will drive the second slideway 320 to move. At this time, the second pin 322 will slide in the second long circular hole 321 to improve the flexibility of the second slideway 320 during movement, facilitating the second slideway 320 to tilt at a larger angle, so as to ensure that the workpiece can smoothly slide along the second slideway 320 to the blanking position 1100.

[0086] In some embodiments, a second lifting mechanism is provided at the riveting position 800. The second lifting mechanism is used to lift the first slideway 220 or the second slideway 320 to increase the tilt angle of the first slideway 220 or the second slideway 320.

[0087] Specifically, in this embodiment, after the workpiece rivets on the first material supporting table 210 are processed, the first material supporting table 210 needs to be unloaded. When unloading the workpiece, while the first lifting mechanism 500 lifts the first material supporting table 210, the second lifting mechanism also lifts the first slideway 220. While ensuring an increase in the tilt angle of the first material supporting table 210, it also increases the tilt angle of the first slideway 220, enabling the processed workpiece on the first material supporting table 210 to smoothly slide along the first slideway 220 to the blanking position 1100, realizing the collection of the processed workpiece.

[0088] Similarly, after the workpiece rivets on the second material supporting table 310 are processed, the second material supporting table 310 needs to be unloaded. When unloading the workpiece, while the first lifting mechanism 500 lifts the second material supporting table 310, the second lifting mechanism also lifts the second slideway 320. While ensuring an increase in the tilt angle of the second material supporting table 310, it also increases the tilt angle of the second slideway 320, enabling the processed workpiece on the second material supporting table 310 to smoothly slide along the second slideway 320 to the blanking position 1100, realizing the collection of the processed workpiece.

[0089] Further, in some embodiments, the second lifting mechanism can be a lifting cylinder.

[0090] In some embodiments, referring to Figures 1 to 3 , the slide rail 400 is a straight track, and the distance L1 that the first fixture 200 moves along the slide rail 400 from the first loading position 900 to the riveting position 800 and the distance L2 that the second fixture 300 moves along the slide rail 400 from the second loading position 1000 to the riveting position 800 satisfy: L1 = L2.

[0091] Specifically, in this embodiment, the first fixture 200 and the second fixture 300 have the same moving distance on the slide rail 400. In this way, the first fixture 200 and the second fixture 300 can be set to have the same sliding speed, so that the first fixture 200 slides from the first loading position 900 to the riveting position 800 and the second fixture 300 slides from the second loading position 1000 to the riveting position 800 in the same sliding time. With the above settings, it is beneficial to adjust the riveting mechanism 100 to the same rivet frequency, thereby facilitating the improvement of the production rhythm of the riveting mechanism 100.

[0092] Furthermore, in some other embodiments, the slide rail 400 can also be a circular track. At this time, several additional fixtures can be added on the slide rail 400 for transporting workpieces. Moreover, several additional riveting mechanisms 100 can be added around the circular track, thereby further improving the riveting efficiency of the workpieces and facilitating the mass production of the workpieces.

[0093] In some embodiments, the first fixture 200 is driven by a first air cylinder, and the first air cylinder drives the first fixture 200 to move along the slide rail 400 between the first loading position 900 and the riveting position 800; the second fixture 300 is driven by a second air cylinder, and the second air cylinder drives the second fixture 300 to move along the slide rail 400 between the second loading position 1000 and the riveting position 800.

[0094] Specifically, in this embodiment, the first air cylinder and the second air cylinder are air cylinders that perform reciprocating linear motion, which is beneficial to ensuring production continuity. By driving the first fixture 200 to move through the first air cylinder and driving the second fixture 300 to move through the second air cylinder, the movement smoothness of the first fixture 200 and the second fixture 300 can be ensured. Furthermore, it can ensure that the workpiece can be stably transported between the loading position and the riveting position 800, effectively preventing the workpiece from jolting, bumping, falling and being damaged during transportation. In addition, the first air cylinder and the second air cylinder are convenient for installation and maintenance, which is beneficial to reducing production costs.

[0095] In some embodiments, the first fixture 200 is driven by a first motor, and the first motor drives the first fixture 200 to move along the slide rail 400 between the first loading position 900 and the riveting position 800; the second fixture 300 is driven by a second motor, and the second motor drives the second fixture 300 to move along the slide rail 400 between the second loading position 1000 and the riveting position 800.

[0096] Specifically, in this embodiment, the forward and reverse rotations of the first motor drive the first jig 200 to perform linear reciprocating motion along the slide rail 400, and the forward and reverse rotations of the second motor drive the second jig 300 to perform linear reciprocating motion along the slide rail 400, which is beneficial to ensuring the continuity of production. To ensure the movement stroke of the first jig 200, the drive shaft of the first motor can be connected with a first drive rod, and the first drive rod is connected to the first jig 200. When the first motor works, the first motor drives the first drive rod to rotate, and the first drive rod drives the first jig 200 to move along the slide rail 400. Similarly, to ensure the movement stroke of the second jig 300, the drive shaft of the second motor can be connected with a second drive rod, and the second drive rod is connected to the second jig 300. When the second motor works, the second motor drives the second drive rod to rotate, and the second drive rod drives the second jig 300 to move along the slide rail 400.

[0097] Furthermore, in some embodiments, the first motor and the second motor can be servo motors. Driving the first jig 200 and the second jig 300 by the servo motors, on the one hand, is beneficial to ensuring the position accuracy of the first jig 200 and the second jig 300, so as to ensure that the first jig 200 can accurately move from the first loading position 900 to the riveting position 800, and ensure that the second jig 300 can accurately move from the second loading position 1000 to the riveting position 800, realizing the precise processing of the workpiece by the riveting mechanism 100. On the other hand, it is beneficial to ensuring the movement smoothness of the first jig 200 and the second jig 300, so as to ensure that the workpiece can be stably conveyed between the loading position and the riveting position 800, effectively preventing the situation of the workpiece being jolted, bumped, dropped and damaged during transportation.

[0098] Correspondingly, another embodiment of the present application further provides a riveting machine, referring to Figure 6 , this riveting machine includes the riveting assembly in any of the above embodiments. This riveting machine further includes a first feeding mechanism 600 and a second feeding mechanism 700. The first feeding mechanism 600 is arranged at the first loading position 900 of the riveting assembly for feeding the first jig 200 of the riveting assembly, and the second feeding mechanism 700 is arranged at the second loading position 1000 of the riveting assembly for feeding the second jig 300 of the riveting assembly. Exemplarily, for example, the first feeding mechanism 600 and the second feeding mechanism 700 can adopt feeding methods such as vibrating disk feeding, magazine feeding, tray feeding, etc.

[0099] Specifically, in this embodiment, the first feeding mechanism 600 can use a first manipulator to transfer the workpiece to be processed onto the first jig 200, and the riveting of the workpiece to be processed is realized through the conveying of the first jig 200. The second feeding mechanism 700 can use a second manipulator to transfer the workpiece to be processed onto the second jig 300, and the riveting of the workpiece to be processed is realized through the conveying of the second jig 300.

[0100] The use of the first feeding mechanism 600 and the second feeding mechanism 700 to achieve workpiece feeding is conducive to liberating human labor, improving production efficiency, and realizing automated production.
