[0048] Referring to Figures 1 to 10 As shown, an automatic riveting machine for longitudinal beams and an automatic end cap installing machine according to an embodiment of the present invention includes:

[0049] A machine table 100;

[0050] A conveying device 200, arranged on the machine table 100, for conveying workpieces to be processed along the conveying direction, and successively provided with one of a pre-placement position 210, a riveting position 220 and an end cap position 230, and the other of the riveting position 220 and the end cap position 230 along its conveying direction. The pre-placement position 210 is used for pre-placing workpieces to be processed.

[0051] A riveting device 300, arranged at the riveting position 220, for installing riveting nuts to workpieces to be processed on the conveying device 200.

[0052] At least one group of end cap installing devices 400, arranged at the end cap position 230, for installing end caps to one end of workpieces to be processed.

[0053] It should be understood that an operator manually places the longitudinal beam to be processed on the pre-placement position 210 of the conveying device 200. The longitudinal beam on the pre-placement position 210 will be transported by the conveying device 200. When passing through the riveting position 220, a plurality of riveting nuts are installed by the riveting device 300. When passing through the end cap position 230, end caps are installed by the end cap installing device 400, realizing the automatic processing of the longitudinal beam and improving the production efficiency.

[0054] Referring to Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown, the conveying device 200 includes a conveying track 240 and a first conveying component 250. The conveying track 240 is arranged on the machine table 100 and sequentially passes through the pre-placement position 210, the riveting position 220, and the end cap position 230. The first conveying component 250 can move along the conveying track 240 to clamp the workpiece to be processed at the pre-placement position 210 to the riveting position 220, and then to the end cap position 230.

[0055] It should be understood that the first conveying component 250 conveys the longitudinal beam along the conveying track 240, so that the longitudinal beam can sequentially pass through the pre-placement position 210, the riveting position 220, and the end cap position 230, realizing the transfer of the longitudinal beam and facilitating the riveting process of the longitudinal beam and the installation of the end cap.

[0056] Refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 As shown, the first conveying component 250 includes a first chassis 251, a first conveying drive component 252, a flipping frame 253, a flipping drive component, and a clamping component 254. The first chassis 251 is slidably arranged on the conveying track 240. The first conveying drive component 252 is arranged on the machine table 100 and is in transmission connection with the first chassis 251 to drive the first chassis 251 to slide along the conveying track 240. The flipping frame 253 is arranged on the first chassis 251. A flipping shaft is provided on the flipping frame 253, and the flipping shaft is in transmission connection with the flipping drive component to rotate around the axis. The clamping component 254 is arranged in the radial direction of the flipping shaft and is used to clamp and fix the workpiece to be processed.

[0057] It should be understood that during conveying, the clamping component 254 is located at the pre-placement position 210 to clamp the longitudinal beam at the pre-placement position 210. After clamping, the flipping frame 253 drives the clamping component 254 to flip, so that except for one side of the longitudinal beam being clamped, the other three sides can be rotated to face upward, facilitating the riveting of the riveting nut to three different sides of the longitudinal beam and realizing the riveting of the riveting nut on the longitudinal beam.

[0058] Among them, the first conveying drive component 252 is a lead screw slider structure. The first chassis 251 is connected to the slider of the lead screw slider structure, and the slider moves along the lead screw to realize the drive of the first conveying drive component 252. Its specific structure and installation position are common knowledge for those skilled in the art and will not be elaborated here.

[0059] Among them, the flipping drive component is a pulley structure. The pulley structure includes a driving pulley and a driven pulley. The driving pulley is in transmission connection with the motor and is transmitted to the driven pulley through a belt. The end of the flipping shaft is inserted into the axis of the driven pulley and rotates under the drive of the driven pulley. Its specific structure and installation position are common knowledge for those skilled in the art and will not be elaborated here.

[0060] Among them, the clamping assembly 254 is a plurality of finger cylinders, and the clamping cavities 3431 of the finger cylinders are arranged in alignment and communication along the axis of the flipping shaft. The specific structure and installation position of the finger cylinders are common knowledge to those skilled in the art and will not be elaborated here.

[0061] Among them, the conveying device 200 further includes a second conveying assembly, and the conveying device 200 also passes through a material receiving position. The material receiving position is located behind the end cap position 230 and is used for receiving materials. The second conveying assembly is located between the end cap position 230 and the material receiving position and is used for... The second conveying assembly has the same structure as the first conveying assembly 250, only the installation positions are different, and will not be elaborated here.

[0062] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in, the conveying device 200 is provided with a pre-placement seat at the pre-placement position 210. The pre-placement seat is arranged on the machine table 100. The pre-placement seat is provided with a placement cavity for placing workpieces to be processed. The pre-placement seat is provided with an outlet for taking out the workpieces to be processed on the side facing the riveting position 220 of the placement cavity. The pre-placement seat is provided with two opposite pre-positioning members 211. The two pre-positioning members 211 are respectively arranged at both ends of the outlet. The two pre-positioning members 211 can move towards each other to squeeze the workpieces to be processed located in the placement cavity.

[0063] Among them, both ends of the outlet refer to: the direction perpendicular to the connection line between the placement cavity and the riveting position 220.

[0064] It should be understood that by setting the pre-placement seat, during processing, the longitudinal beam can be manually or mechanically automatically placed in the placement cavity of the placement seat. The two ends of the longitudinal beam located in the outlet are squeezed by the pre-positioning members 211 to achieve the positioning of the two ends of the longitudinal beam in the outlet, and the positioning is more accurate. Among them, when the longitudinal beam is in the vertical direction, it can be positioned by its own gravity; when the clamping assembly 254 moves towards the outlet and clamps the longitudinal beam at the outlet, it will squeeze the longitudinal beam along the direction away from the riveting position 220 of the outlet to achieve the positioning in the direction of the connection line between the placement cavity and the riveting position 220, and achieve the three-dimensional positioning of the longitudinal beam at the pre-placement position 210, which is convenient for taking out.

[0065] Among them, the finger length of the finger cylinder of the clamping assembly 254 is less than the length of the longitudinal beam along the direction away from the riveting position 220 of the outlet, which is convenient for squeezing the longitudinal beam.

[0066] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the conveying device 200 is provided with an end cover mounting seat 231 at the end cover position 230. The end cover mounting seat 231 includes a fixed seat 2311, a pressing seat 2312, and two end pressing members 2313. The fixed seat 2311 is fixedly arranged on the machine table 100. A fixed groove is provided on the surface of the fixed seat 2311 away from the machine table 100. The pressing seat 2312 is arranged on the machine table 100, above the fixed seat 2311, and is arranged opposite to the fixed seat 2311, and is used to clamp the workpiece to be processed into the fixed groove. The end pressing members 2313 are arranged on the machine table 100 at both ends of the end cover position 230 to position both ends of the workpiece to be processed.

[0067] It should be understood that when the longitudinal beam is conveyed to the end cover position 230 by the conveying device 200, the longitudinal beam will be positioned in the conveying direction through the fixed groove on the fixed seat 2311, and the longitudinal beam in the fixed groove will be extruded by the pressing seat 2312, so that the longitudinal beam is fixed. And both ends of the longitudinal beam have been fixed through the pre-placement position 210, realizing the fixation of the overall position of the longitudinal beam, which is convenient for the installation of the end cover.

[0068] It should be understood that the edge of the fixed groove is provided with a chamfer, which is convenient for the longitudinal beam to be smoothly inserted into the fixed groove, and the feasibility is higher.

[0069] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7 As shown in the figure, the riveting device 300 includes a riveting fixed table 310, a riveting sliding table 320, a nut conveying component 330, a nut clamping component 340, and a riveting component 350. The riveting fixed table 310 is arranged on the machine table 100, erected above the conveying device 200. The riveting sliding table 320 is slidably arranged on the riveting fixed table 310, and the riveting sliding table 320 can move along the erection direction of the riveting fixed table 310. The nut conveying component 330 and the riveting component 350 are both arranged on the riveting sliding table 320. A riveting end is provided on the riveting component 350, and the riveting end extends out of the riveting fixed table 310 and the riveting sliding table 320 from the side where the conveying device 200 is located. The nut clamping component 340 is arranged below the riveting end and can move between directly below the nut conveying component 330 and the riveting end to transfer the nut on the nut conveying component 330 to directly below the riveting end.

[0070] It should be understood that the conveying component conveys the longitudinal beam to the riveting position 220. The nut conveying component 330 on the riveting fixed table 310 conveys the nut to the nut clamping component 340, and the riveting end of the riveting component 350 squeezes the nut on the nut clamping component 340 towards the longitudinal beam at the riveting position 220, so as to realize riveting.

[0071] After processing a rivet nut on the longitudinal beam, the nut conveying assembly 330, the nut clamping assembly 340 and the rivet assembly 350 will move together along the rivet sliding table 320 to move to the next rivet nut on the longitudinal beam for rivet.

[0072] Among them, when constructing the rivet nuts on different surfaces of the longitudinal beam, the clamping assembly 254 will be flipped through the flip frame 253, and then the longitudinal beam will be flipped, so that the rivet device 300 can realize the processing on different surfaces of the longitudinal beam, and when the positions of the rivet nuts on different surfaces of the longitudinal beam are different, the position of the longitudinal beam in the conveying direction can be adjusted by the first conveying drive assembly 252, and the adjustment perpendicular to the conveying direction can be achieved by the rivet sliding table 320, so as to realize the planar positioning of the rivet holes on the same surface of the longitudinal beam, and the processing is more accurate.

[0073] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the nut conveying assembly 330 includes a vibration plate 331, a nut loading assembly 332 and an inclined nut conveying track 333. The top of the vibration plate 331 is connected to the high end of the nut conveying track 333. The lower end of the nut conveying track 333 is provided with a nut loading port. The nut loading assembly 332 is arranged on the lower end face of the nut conveying track 333 to press the nut through the nut loading port.

[0074] It is worth understanding that the nuts are automatically arranged and neatly conveyed by the vibration plate 331. After being conveyed to the nut conveying track 333, they are moved along the high end of the nut conveying track 333 to the low end of the nut conveying track 333. After reaching the low end, the nuts can be pressed down by the nut feeding assembly 332 so that the nuts are ejected from the nut feeding port. After one nut is ejected, the next nut is automatically clamped to the top of the nut feeding port under the action of gravity. The structure and installation of the vibration plate 331 are common sense for technicians in this field and will not be described in detail here.

[0075] The nut feeding assembly 332 includes a feeding block and a feeding cylinder, and the feeding cylinder is transmission-connected to the feeding block so as to extrude the nut through the movement of the feeding block.

[0076] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the nut clamping assembly 340 includes a clamping track 341, a clamping driving member 342, and a clamping substrate 343. The clamping track 341 is installed above the conveying device 200. The clamping substrate 343 is slidably connected to the clamping track 341 and is in transmission connection with the clamping driving member 342 to drive the clamping substrate 343 to slide along the clamping track 341. A clamping cavity 3431 capable of riveting nuts is provided on the clamping substrate 343. The axis of the clamping cavity 3431 is arranged towards the side where the riveting end is located, and the clamping cavity 3431 can be opened when subjected to axial pressure to release the riveting nut.

[0077] It should be understood that the clamping substrate 343 moves along the clamping track 341 through the clamping driving member 342. When the clamping substrate 343 moves to the low end of the nut conveying track 333, the nut on the nut conveying track 333 will be pushed into the clamping cavity 3431 of the clamping substrate 343 under the action of the nut feeding assembly 332. Through the movement of the clamping substrate 343, the nut moves below the riveting end. And when the riveting end of the riveting assembly 350 presses towards the longitudinal beam direction, the clamping cavity 3431 opens, and the nut is driven by the riveting end to pass through the clamping cavity 3431 and connect with the longitudinal beam for riveting.

[0078] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the clamping substrate 343 is provided with a riveting channel in the same direction on the connection line between the riveting end and the riveting position 220. Two opposite clamping plates 3432 capable of closing the riveting channel are provided in the riveting channel. Clamping arc holes are provided on the opposite surfaces of the clamping plates 3432. The two clamping arc holes are arranged opposite to each other and enclose the clamping cavity 3431 together. One side of the clamping plate 3432 away from the other clamping plate 3432 is elastically hinged or elastically telescoped to the clamping substrate 343.

[0079] It should be understood that the two clamping plates 3432 are opened when subjected to axial pressure by being elastically hinged or elastically telescoped to the substrate, which is convenient for releasing the nut for riveting.

[0080] Specifically, when the clamping plate 3432 is elastically hinged to the substrate, one side of the clamping plate 3432 away from the other clamping plate 3432 is hinged to the clamping substrate 343, and a torsion spring is sleeved on the hinge axis of the clamping plate 3432 and the clamping substrate 343. After the substrate is elastically deformed and opened under pressure, the two clamping plates 3432 rotate to open the riveting channel, and the torsion spring will be in a compressed or stretched state, accumulating a certain amount of elastic potential energy. When the pressure disappears, the torsion spring releases the elastic potential energy, causing the two clamping plates 3432 to reset and close the riveting channel to receive the riveting nut through the clamping cavity 3431.

[0081] As another implementation, when the clamping plate 3432 is elastically telescopically connected to the substrate, there are two opposite avoidance holes in the clamping substrate 343 and the riveting channel. The two clamping plates 3432 are respectively arranged in the two avoidance holes and are elastically connected to the side away from the clamping plate 3432 in the avoidance holes by springs. When an external force acts on the clamping plate 3432, the spring will be compressed, so that it shrinks into the avoidance hole, realizing that the clamping plate 3432 opens the riveting channel. When the external force disappears, the spring returns to its original state under the action of its own elastic potential energy, thereby driving the clamping plate 3432 to reset, realizing the closing of the riveting channel, and the riveting nut can be received through the clamping cavity 3431.

[0082] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 as shown, the riveting assembly 350 includes a riveting gun 351 and a riveting driving member 352. The riveting driving member 352 is arranged on the riveting sliding table 320. The riveting driving member 352 has a stroke of moving towards the machine table 100. The riveting gun 351 is arranged on the riveting driving member 352 and can move under the drive of the riveting driving member 352. The riveting gun 351 extends from the side where the conveying device 200 is located and is arranged on the riveting fixing table 310 and the riveting sliding table 320, and the gun head of the riveting gun 351 is arranged towards the machine table 100.

[0083] It should be understood that after the clamping cavity 3431 of the clamping substrate 343 is aligned with the riveting end, the riveting gun 351 will move towards the longitudinal beam on the riveting position 220 through the riveting driving member 352, so as to realize the extrusion of the two clamping plates 3432 in the riveting channel, and make the riveting nut move away from the riveting position 220 to the longitudinal beam, realizing riveting.

[0084] Among them, the specific structure and installation method of the riveting gun 351 are common knowledge for those skilled in the art and will not be elaborated here.

[0085] Referring to Figure 1 as shown, the number of the end cover installation devices 400 is two, and they are oppositely arranged on both sides of the conveying device 200.

[0086] It should be understood that by setting two end cover installation devices 400, the end covers are installed at both ends of the longitudinal beam, and the installation efficiency is higher.

[0087] Referring to Figure 8 , Figure 9 and Figure 10As shown in the figure, a storage component 410, a feeding component 420, and an end cap mounting component 430 are provided on the end cap mounting device 400. A feeding position 411 is provided on the storage component 410. The storage component 410 can store multiple end caps and convey the end caps to the feeding position 411. A clamping position 421 is provided on the feeding component 420. The feeding component 420 has a stroke of moving between the feeding position 411 and the clamping position 421 to drive the end cap on the feeding position 411 to the clamping position 421. The end cap mounting component 430 has a stroke of moving between the clamping position 421 and the end cap position 230. The end cap mounting component 430 is used to clamp the end cap on the clamping position 421 and mount it to one end of the longitudinal beam at the end cap position 230.

[0088] It should be understood that multiple end caps are pre-placed in the storage component 410. When installation is required, the end caps are conveyed to the feeding position 411. The feeding component 420 conveys the end cap on the feeding position 411 to the clamping position 421, clamps the end cap on the clamping position 421 through the end cap mounting component 430, and mounts the end cap to the end of the longitudinal beam through the end cap mounting component 430, realizing the automatic assembly of the end cap.

[0089] Refer to Figure 8 、 Figure 9 and Figure 10 As shown in the figure, the storage component 410 includes a storage frame. A through hole facing the clamping position 421 is provided at the bottom of the storage frame. The through hole can accommodate the end cap to pass through, forming the feeding position 411.

[0090] It should be understood that multiple end caps are pre-stacked vertically in the storage frame. When the end cap at the bottom of the storage frame is moved to the clamping position 421 by the feeding component 420, the subsequent end caps will be automatically loaded onto the feeding position 411 under the action of their own weight, realizing the automatic feeding of the end caps.

[0091] Refer to Figure 8 、 Figure 9 and Figure 10 As shown in the figure, the feeding component 420 includes a pushing member 422 and a squeezing member 423 arranged oppositely. The feeding position 411 and the clamping position 421 are successively arranged on the connection line between the pushing member 422 and the squeezing member 423. Both the pushing member 422 and the squeezing member 423 have a stroke of moving between the feeding position 411 and the clamping position 421. The pushing member 422 and the squeezing member 423 can jointly squeeze the end cap at the feeding position 411 and move to the clamping position 421 after being squeezed and fixed for the end cap mounting component 430 to clamp.

[0092] It is worth understanding that the end cap located on the feeding position 411 is pressed and fixed by the pushing member 422 and the extruding member 423 together. After the extrusion, the pushing member 422 extends toward the extruding member 423, and the extruding member 423 retracts to transfer the clamped end cap to the clamping position 421. The end cap has been fixed on the feeding position 411, and is also pressed and fixed in the subsequent transfer process, so that the position of the end cap is fixed during the transfer process, so as to improve the subsequent installation accuracy.

[0093] Reference Figure 8 , Figure 9 and Figure 10 As shown, the end cap installation device 400 also includes a gluing assembly 440, which is arranged above the clamping position 421 and can move toward the clamping position 421 to glue the end cap on the clamping position 421. The end cap installation assembly 430 can rotate the clamped end cap with the direction from the clamping position 421 to the end cap position 230 as the axis.

[0094] It is worth understanding that when the end cap position 230 is on the clamping position 421, the gluing assembly 440 will glue the end cap on the clamping position 421. During the gluing, the end cap installation assembly 430 rotates to glue all surfaces of the end cap to facilitate subsequent installation.

[0095] Reference Figure 8 , Figure 9 and Figure 10 As shown, the end cover mounting assembly 430 includes an end cover mounting rail 431, an end cover mounting drive member 432, a rotating table 433, a rotating drive member 434 and an end cover clamping member 435. The end cover mounting rail 431 is arranged along the direction from the clamping position 421 to the end cover position 230, the rotating table 433 is slidably arranged on the end cover mounting rail 431, the end cover mounting drive member 432 is transmission-connected with the rotating table 433 to drive the rotating table 433 to move along the end cover mounting rail 431, the rotating drive member 434 is arranged on the rotating table 433, and is transmission-connected with the end cover clamping member 435 to drive the end cover clamping member 435 to rotate with the line connecting the clamping position 421 to the end cover position 230 as the axis, the end cover clamping member 435 is located on the side of the rotating drive member 434 facing the end cover position 230, and the end cover clamping member 435 can clamp the end cover.

[0096] It should be understood that the end cap installation driving member 432 drives the end cap clamping member 435 on the rotating table 433 to move along the end cap installation track 431. When it moves to the clamping position 421, the end cap clamping member 435 clamps the end cap between the pushing member 422 and the squeezing member 423. After the end cap clamping member 435 clamps and fixes the end cap, the pushing member 422 and the squeezing member 423 move in the reverse direction to reset. The end cap clamping member 435 will rotate driven by the rotation driving member 434. After gluing one side of the end cap is completed, it is flipped to the other side of the end cap without gluing until glue is applied to all four sides of the end cap. After the gluing is completed, the end cap clamping member 435 clamps the end cap and moves it towards the end of the longitudinal beam at the end cap position 230, and inserts the end cap into the end of the longitudinal beam to achieve the installation of the end cap at the end of the longitudinal beam. The installation is automated and the installation efficiency is higher.

[0097] Wherein, on one side of the end cap clamping member 435 facing the longitudinal beam, there are also two opposite and retractable glue scraping plates 441, and the glue scraping plates 441 can scrape off the excess glue on the end cap.

[0098] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
