DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other alternative embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] As shown in Figures 2 to 11 , as an embodiment of the riveting device 100, the riveting device 100 can rivet and press the workpiece 200 shown in Figure 1 , the workpiece 200 includes a bottom plate 210 and a side plate 220, the side plate 220 is arranged around the bottom plate 210 and is perpendicular to the bottom plate 210, the side plate 220 has a plurality of rivet holes, and the riveting device 100 rivets and presses the rivet 300 through the rivet holes.

[0033] Specifically, as shown in Figures 2 to 11 , the riveting device 100 includes a cabinet 10, a lower die mechanism 20, and an upper die mechanism 30, wherein the lower die mechanism 20 is installed on the cabinet 10, as shown in Figures 3 to 6As shown, the lower die mechanism 20 includes a lower die head 21, a lower die mounting base 22, a lower ejector rod 23, and a lower die telescopic member 24. The lower die head 21 is hollow and can accommodate the rivet 300. The lower die mounting base 22 has a mounting cavity 225 that can accommodate the lower die head 21, so that the lower die head 21 can be inserted and fixed in the mounting cavity 225. The lower ejector rod 23 is partially mounted in the lower die mounting base 22 and located below the lower die head 21. The lower die telescopic member 24 is connected with the lower ejector rod 23 and acts on the lower ejector rod 23, so as to move the lower ejector rod 23 upward and push the rivet 300 in the lower die head 21 upward. In combination with Figure 7 The upper die mechanism 30 is mounted on the cabinet 10. The upper die mechanism 30 includes an upper die telescopic member 31, an upper die riveting rod 32, and an upper die head 33. The top of the upper die riveting rod 32 is connected with the upper die telescopic member 31. The upper die head 33 is detachably mounted on the bottom of the upper die riveting rod 32 and corresponds to the position of the lower die head 21. When the upper die telescopic member 31 acts on the upper die riveting rod 32 to move downward, the upper die head 33 rivets the rivet 300.

[0034] In this embodiment, when riveting the side plate 220, the rivet hole on the side plate 220 is moved to directly above the lower die head 21 on the lower die mounting base 22 and is aligned with the lower die head 21 on the lower die mounting base 22, so that the lower die head 21 is concentric with the rivet hole. Then the lower ejector rod 23 pushes the rivet 300 pre-stored in the lower die head 21 upward, so that the rivet 300 passes through the rivet hole on the side plate 220. Finally, the upper die riveting rod 32 is aligned with the rivet 300 to rivet, so that the rivet 300 is deformed and fixed on the side plate 220. The position of the side plate 220 is moved and the above process is repeated, so that different rivet holes on the side plate 220 are riveted.

[0035] It should be noted that the lower die telescopic member 24 and the upper die telescopic member 31 in this embodiment are both telescopic cylinders or electric telescopic rods, or both include linear motors, lead screws, belts, slides, and sliders, etc., which are designed to realize linear motion. These are known to those skilled in the art, and the telescopic members appearing below have the same function and will not be described again.

[0036] Further, in order to improve the degree of automation of the riveting device 100, the riveting device 100 further has a moving jig (not shown in the figure) for clamping the workpiece 200. The moving jig can drive the workpiece 200 to displace in the longitudinal and transverse directions, so that different rivet holes on the side plate 220 can be selectively aligned with the lower die head 21, and automatic positioning of the rivet holes is realized one by one.

[0037] Further, as shown in FIG. 2, the riveting device 100 further includes a rivet feeding mechanism 40. The rivet feeding mechanism 40 is mounted on the cabinet 10 and includes a rivet feeding base 41, a rivet feeding telescopic member 42, and a rivet feeding rod 43. The top of the rivet feeding rod 43 is connected with the rivet feeding telescopic member 42. The rivet feeding base 41 is detachably mounted on the bottom of the rivet feeding rod 43 and corresponds to the position of the lower die head 21. When the rivet feeding telescopic member 42 acts on the rivet feeding rod 43 to move downward, the rivet feeding rod 43 is aligned with the lower die head 21 on the lower die mounting base 22. Figure 4 and Figure 6As shown, since the downward impact force of the upper die riveting rod 32 is very large during the riveting process of the rivet 300, it will act on the lower ejector rod 23. In order to improve the carrying capacity of the lower ejector rod 23, the lower die mechanism 20 further comprises a bearing assembly 25 arranged in the lower die mounting seat 22, which bears the impact from the upper die riveting rod 32 together with the lower ejector rod 23.

[0038] Specifically, as shown in Figure 4 and Figure 6 , the bearing assembly 25 comprises a bearing block 251 and a bearing telescopic part 252 which can drive the bearing block 251 to approach or move away from the lower ejector rod 23, and the bearing block 251 is provided with a first plug-in part 2511 which is a plug-in clamping groove. Figure 4 In the middle, the lower ejector rod 23 has a second plug-in part 231 which is a flat structure after the cylindrical structure on the lower ejector rod 23 is cut off, which can be inserted into the plug-in clamping groove, that is, the first plug-in part 2511 and the second plug-in part 231 can be plugged together, and the riveting force (impact force) exerted by the upper die riveting rod 32 is jointly borne by the bearing block 251 and the lower ejector rod 23.

[0039] Further, as shown in Figure 5 , the lower die mechanism 20 further comprises a locking assembly 26 arranged on the lower die mounting seat 22, which, in the locked state, limits the lower die head 21 from leaving the mounting cavity 225; the locking assembly 26 in the unlocked state allows the lower die head 21 to leave the mounting cavity 225, thereby facilitating the detachable installation of the lower die head 21 on the lower die mounting seat 22.

[0040] Specifically, in this embodiment, the locking assembly 26 comprises a first locking part 261 and a locking telescopic part 262 which can drive the first locking part 261 to approach or move away from the lower die head 21, and the lower die head 21 is provided with a second locking part 211 which is adapted to the first locking part 261 along the circumference, so that the first plug-in part 2511 and the second plug-in part 231 can be engaged together. As shown in Figure 5 , the first locking part 261 is a plug-in clamping block; as shown in Figure 4 , the lower die head 21 is a hollow cylindrical structure, and the second locking part 211 is an annular clamping groove arranged circumferentially at the bottom of the lower die head 21, so that the first locking part 261 can be inserted into the second locking part 211 to prevent the lower die head 21 from leaving the mounting cavity 225; when replacing the lower die head 21, the first locking part 261 moves away from the second locking part 211 under the action of the locking telescopic part 262, so that the lower die head 21 can be taken out from the mounting cavity 225.

[0041] In other embodiments, the locking assembly 26 employs other structural members or mechanisms, such as a plurality of clamping jaws that can automatically clamp the lower die head 21, etc., as long as the lower die head 21 movement can be restricted.

[0042] Further, as shown in Figure 4 , the lower die mounting seat 22 includes a first mounting seat body 221, a second mounting seat body 222, and a third mounting seat body 223, and a protective cover 224, the first mounting seat body 221 is part of the cabinet 10; the second mounting seat body 222 is mounted on the first mounting seat body 221, and the third mounting seat body 223 is mounted on the second mounting seat body 222. The above-mentioned lower ejector rod 23 and lower die telescopic member 24 are arranged in the first mounting seat body 221, and are protected by the protective cover 224; the load-bearing assembly 25 is arranged in the second mounting seat body 222; the locking assembly 26 is connected with the third mounting seat body 223; in combination Figure 5 , the third mounting seat body 223 includes a third seat body part 2231 and a seat body cover 2232, the third seat body part 2231 has a locking slot 2233, and the seat body cover 2232 can close the locking slot 2233; the first locking part 261 is slidingly arranged in the locking slot 2233, and under the action of the locking telescopic member 262, moves into or out of the mounting cavity 225, thereby realizing locking or unlocking of the lower die head 21.

[0043] Further, in combination Figure 9 and Figure 10 and Figure 11 , in order to further improve the degree of automation of the riveting device 100, the riveting device 100 further includes a rivet conveying mechanism 60, which automatically conveys the rivet 300 into the lower die head 21.

[0044] Specifically, the rivet conveying mechanism 60 includes an electric clamping jaw 61 and a third longitudinal telescopic member 62, wherein the electric clamping jaw 61 has two symmetrical clamping arms 611 and a telescopic support plate 612, the support plate 612 is located below the two clamping arms 611 and is used to carry the rivet 300; when the rivet 300 falls on the support plate 612, it can be clamped by the two clamping arms 611; the third longitudinal telescopic member 62 acts on the electric clamping jaw 61, so that the electric clamping jaw 61 can move closer to or away from the lower die head 21 mounted on the lower die mounting seat 22 in the longitudinal direction, thereby realizing automatic placement of the rivet 300 into the lower die head 21, the process is as follows:

[0045] When the electric clamping jaw 61 clamps the rivet 300 through the two clamping arms 611, it moves towards the lower die head 21 under the drive of the third longitudinal telescopic member 62. When the support plate 612 contacts the lower die head 21, the support plate 612 retracts into the electric clamping jaw 61 until the two clamping arms 611 move to the upper side of the lower die head 21. Then the two clamping arms 611 release the rivet 300, which falls into the lower die head 21. Subsequently, the electric clamping jaw 61 moves away from the lower die head 21 under the drive of the third longitudinal telescopic member 62. The above process is repeated to automatically add rivets 300 to the lower die head 21.

[0046] Further, in the present embodiment, the side plate 220 has a plurality of rivet holes of different specifications, and the required rivets 300 are also different in type. Therefore, the upper die head 33 and the lower die head 21 used in the rivet pressing process are also different in type, i.e., one type of rivet 300 corresponds to one set of corresponding upper die head 33 and lower die head 21. Therefore, the riveting device 100 further comprises an upper riveting mechanism 70, a lower die head replacement mechanism 40, and an upper die head replacement mechanism 50. The upper riveting mechanism 70 provides different specifications and types of rivets 300 to the rivet conveying mechanism 60. The lower die head replacement mechanism 40 replaces the corresponding type of lower die head 21 for the lower die mechanism 20. The upper die head replacement mechanism 50 replaces the corresponding type of upper die head 33 for the upper die mechanism 30.

[0047] As shown in Figure 2 , Figure 9 and Figure 10 , the riveting device 100 comprises an upper riveting mechanism 70, which comprises a plurality of upper riveting assemblies, each of which is used to feed one type of rivet 300. Each upper riveting assembly comprises a vibrating tray 71, a conveying pipe (not shown), and a discharging nozzle 72. The vibrating tray 71 is used to store rivets 300. The conveying pipe connects the vibrating tray 71 and the discharging nozzle 72, and is used to convey rivets 300 to the discharging nozzle 72. The discharging nozzle 72 is used to output rivets 300.

[0048] As shown in Figure 10 , the upper riveting mechanism 70 further comprises a discharging nozzle storage mold 73. A plurality of discharging nozzles 72 are arranged on the discharging nozzle storage mold 73. The discharging nozzle storage mold 73 is connected to the first transverse telescopic member 42, which can drive the discharging nozzle storage mold 73 to move in the transverse direction. The required discharging nozzle 72 is selectively brought close to the electric clamping jaw 61, so that the rivet 300 of the corresponding type can fall on the support plate 612 and be clamped by the two clamping arms 611.

[0049] As shown in Figure 8 and Figure 9As shown, the lower die head replacement mechanism 40 comprises a lower die head storage die 41, a first longitudinal telescopic member 44, a first vertical telescopic member 43 and a first horizontal telescopic member 42, wherein the lower die head storage die 41 has a plurality of first storage cavities 411 capable of storing a plurality of lower die heads 21 of different specifications and models, and the first storage cavities 411 are provided with springs and / or steel balls capable of clamping the lower die heads 21 to prevent the lower die heads 21 from falling off; the first longitudinal telescopic member 44 is connected to the lower die head storage die 41 and acts on the lower die head storage die 41, so that the lower die head storage die 41 can move towards or away from the lower die mounting seat 22 in the longitudinal direction; the first vertical telescopic member 43 acts on the first longitudinal telescopic member 44, so that the lower die head storage die 41 can move towards or away from the lower die mounting seat 22 in the vertical direction; the first horizontal telescopic member 42 is connected to the first vertical telescopic member 43 and acts on the first vertical telescopic member 43, so that the lower die head storage die 41 can move towards or away from the lower die mounting seat 22 in the horizontal direction.

[0050] That is, in the lower die head replacement mechanism 40, the first longitudinal telescopic member 44, the first vertical telescopic member 43 and the first horizontal telescopic member 42 can respectively drive the lower die head storage die 41 to move towards or away from the lower die mounting seat 22 in the longitudinal direction, the vertical direction and the horizontal direction, so as to realize the installation of the lower die head 21 stored in the lower die head storage die 41 on the lower die mounting seat 22 or the replacement of the lower die head 21 installed on the lower die mounting seat 22.

[0051] Further, the process of the lower die head replacement mechanism 40 replacing the lower die head 21 on the lower die mounting seat 22 is as follows:

[0052] Firstly, the lower die head 21 on the lower die mounting seat 22 is taken out, specifically: the first longitudinal telescopic member 44 and the first horizontal telescopic member 42 drive the lower die head storage die 41 to move to the upper side of the lower die mounting seat 22, the empty first storage cavity 411 is aligned with the lower die head 21 on the lower die mounting seat 22, then the first vertical telescopic member 43 drives the lower die head storage die 41 to move downwards, the lower die head 21 is placed in the empty first storage cavity 411, and then the locking assembly 26 inside the lower die mounting seat 22 releases the locking of the lower die head 21, so that the lower die head 21 can be taken out of the mounting cavity 225 during the upward movement of the lower die head storage die 41 driven by the first vertical telescopic member 43.

[0053] Secondly, the required lower die head 21 is installed on the lower die mounting seat 22, specifically: the first longitudinal telescopic member 44 and the first transverse telescopic member 42 drive the lower die head storage die 41 to move to the upper side of the lower die mounting seat 22, the lower die head 21 pre-stored in the first storage cavity 411 is aligned with the installation cavity 225 on the lower die mounting seat 22, and then the first vertical telescopic member 43 drives the lower die head storage die 41 to move downward, so that the lower die head 21 is placed in the installation cavity 225, and then the locking assembly 26 inside the lower die mounting seat 22 triggers the locking of the lower die head 21, so that the first vertical telescopic member 43 can release the restriction of the lower die head 21 during the upward movement of the lower die head storage die 41.
