[0046] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0050] like Figure 1 As shown, the embodiment of the present application provides a riveting device, which includes a riveting unit 1 and a turntable 3. The turntable 3 can rotate relative to the riveting unit 1. Figure 6 As shown, the turntable 3 includes at least three mounting seats 31, which are used to load workpieces 7, and the workpieces 7 can rotate with the turntable 3. The workpieces 7 can be placed on or removed from the mounting seats 31 by manual operation or other equipment to achieve loading and unloading.

[0051] The riveting unit 1 includes at least two heating modules 1 and one cold riveting module 2, and the number of mounting seats 31 configured is greater than or equal to the sum of the number of heating modules 1 and cold riveting modules 2 configured. For example, when the riveting equipment is provided with two heating modules 1 and one cold riveting module 2, the riveting equipment is provided with at least three mounting seats 31, so that each heating module 1 and cold riveting module 2 can be in a working state, thereby improving processing efficiency. Along the rotation direction of the turntable 3, each heating module 1 in the riveting unit 1 is located on the upstream side of the cold riveting module 2, and the heating module 1 and the cold riveting module 2 are arranged in sequence along the rotation direction of the turntable 3, which can meet the processing steps of heating the workpiece 7 first and then riveting it. The workpiece 7 can rotate with the turntable 3 to the positions corresponding to the heating module 1 and the cold riveting module 2 in sequence, so that the heating module 1 and the cold riveting module 2 can process the workpiece 7 respectively.

[0052] The riveting equipment provided in the embodiment of the present application is used to implement hot air cold riveting. The workpiece 7 is first heated by the heating module 1 to soften the workpiece 7, and then the workpiece 7 is reshaped by the cold riveting module 2 to achieve riveting. In current riveting equipment, during the processing process, the workpiece 7 is first transported to the heating component for heating. After the heating is completed, the workpiece 7 is moved to the riveting component for riveting. However, the transport component will not transport a new workpiece 7 for heating until the riveting is completed. As a result, the heating component is idle for a long time while waiting for riveting, resulting in high processing costs and low processing efficiency. The riveting equipment provided in the embodiment of the present application includes a riveting unit 1, and the riveting unit 1 includes at least two heating modules 1. The two heating modules 1 can heat different workpieces 7 respectively. For example, after the first workpiece 7 is heated for a period of time by the first heating module 1, it continues to rotate through the turntable 3 to the position of the second heating module 1 and continues to be heated until it is completely softened. The second workpiece 7 can also be synchronously moved to the position of the first heating module 1 for heating. The first workpiece 7 then moves to the position of the cold riveting module 2 to complete the riveting. The second workpiece 7 synchronously moves to the second heating module 1 to be heated until it is completely softened. By setting multiple heating modules 1 to work simultaneously, the heating process of the workpiece 7 can be divided into multiple steps, and multiple workpieces 7 can be heated at the same time, which can reduce the idle running time of the heating module 1 when the cold riveting module 2 is working, reduce processing costs and improve processing efficiency.

[0053] like Figure 1 As shown, in a possible embodiment, the riveting equipment has a loading position 5, the heating module 1 includes a first heating module 1 and a second heating module 1, the loading position 5, the first heating module 1, the second heating module 1 and the cold riveting module 2 are arranged in sequence at equal intervals along the circumference of the turntable 3, and the mounting seat 31 is respectively arranged corresponding to the loading position 5, the first heating module 1, the second heating module 1 and the cold riveting module 2.

[0054] The loading position 5 is a relatively open position along the circumference of the turntable 3 where no modules are set. The loading position 5 is not blocked by other equipment or components, which facilitates loading and unloading. The loading position 5 is used for placing the workpiece 7 on the mounting seat 31 manually or with other equipment, or for removing the processed workpiece 7 from the mounting seat 31. During the rotation of the turntable 3, the mounting seat 31 can pause when it moves to the area corresponding to the loading position 5 to complete loading and unloading. The riveting equipment provided in the embodiment of the present application can be provided with two heating components 1, one riveting component 2 and one loading position 5, and the mounting seat 31 can be provided with four mounting seats 31 corresponding to each other.

[0055] like Figure 2 As shown, in a possible embodiment, the heating module 1 includes a first bracket 11, a first driving member 12, a first connecting plate 13 and a hot air gun 14. The first driving member 12 is installed on the first bracket 11. The first bracket 11 is used to support the heating module 1, and the heating module 1 can be installed and fixed by the first bracket 11. The first connecting plate 13 is connected to the first driving member 12, and the hot air gun 14 is installed on the first connecting plate 13. The first driving member 12 is used to drive the hot air gun 14 to move along the height direction Z of the riveting equipment through the first connecting plate 13. When heating the workpiece 7, the hot air gun 14 can move in a direction close to the workpiece 7, thereby reducing the distance between the hot air gun 14 and the workpiece 7 to achieve a good heating and softening effect and improve the heating efficiency. After heating is completed, the hot air gun 14 can move in a direction away from the workpiece 7 to avoid the workpiece 7 so that the workpiece 7 can rotate smoothly with the turntable 3.

[0056] like Figure 2 As shown, in one possible embodiment, the first connecting plate 13 includes an upper positioning plate 131 and a lower positioning plate 132, the upper positioning plate 131 and the lower positioning plate 132 are respectively connected to the first bracket 11, the lower positioning plate 132 is located on the side of the upper positioning plate 131 close to the turntable 3, one end of the hot air gun 14 is connected to the upper positioning plate 131, and the other end of the hot air gun 14 is connected to the lower positioning plate 132. The overall length of the hot air gun 14 is relatively long. By providing the upper positioning plate 131 and the lower positioning plate 132, the two ends of the hot air gun 14 can be fixed respectively, thereby improving the stability of the hot air gun 14.

[0057] like Figure 3As shown, in one possible embodiment, the hot air gun 14 includes a hot air gun body 141 and a hot air gun nozzle 142. The hot air gun nozzle 142 is located at the end of the hot air gun body 141. The hot air gun body 141 is mounted on the positioning upper plate 131, and the hot air gun nozzle 142 is mounted on the positioning lower plate 132. The interior of the hot air gun body 141 can be used to set a heating element and a fan. For example, a resistance wire can be set. When an electric current passes through it, heat is generated to heat the air. The fan is used to blow the heated air out of the hot air gun nozzle 142. The hot air nozzle 142 is used to concentrate and guide the flow of heated air. The hot air nozzle 142 can be set to different shapes to control the flow rate and flow rate to meet different heating requirements.

[0058] like Figure 2 As shown, in one possible embodiment, the first connecting plate 13 includes a heat insulating plate 133, the heat insulating plate 133 is connected to the air gun nozzle 142, and the heat insulating plate 133 is located on the side of the positioning lower plate 132 close to the turntable 3. When heating the workpiece 7, the positioning plate is relatively close to the workpiece 7, and the positioning lower plate 132 is usually made of metal with good thermal conductivity, so the temperature of the positioning lower plate 132 is also easy to increase when heated. The heat insulating plate 133 can be provided with an opening to allow the air gun nozzle 142 to pass through the heat insulating plate 133. By providing the heat insulating plate 133, the positioning lower plate 132 and the workpiece 7 can be relatively isolated during heating, thereby preventing the positioning lower plate 132 from being overly hot and affecting the area of ​​the workpiece 7 that does not need to be heated.

[0059] like Figure 4 As shown, in a possible embodiment, the cold riveting module 2 includes a second bracket 21, a second driving member 22, a second connecting plate 23 and a cold riveting column 24. The second bracket 21 can support the cold riveting module 2 as a whole, and the second driving member 22 is installed on the second bracket 21. The second connecting plate 23 is connected to the second driving member 22, and the cold riveting column 24 is installed on the second connecting plate 23. The second connecting plate 23 can be "L"-shaped, wherein the vertical part is connected to the second driving member 22, and the horizontal part is used to install the cold riveting column 24. The second driving member 22 is used to drive the second connecting plate 23 to move, thereby driving the cold riveting column 24 to move along the height direction Z of the riveting equipment. Driven by the second driving member 22, the cold riveting column 24 can move in the direction close to the workpiece 7 and contact the workpiece 7, so that the heated and softened part of the workpiece 7 is deformed to complete the riveting.

[0060] like Figure 5As shown, in one possible embodiment, the cold rivet column 24 includes an adapter 241 and a cold rivet head 242. The second connecting plate 23 has a mounting hole, and the cold rivet head 242 passes through the mounting hole to connect with the adapter 241. The cold rivet head 242 is located on the side of the second connecting plate 23 close to the turntable 3. The adapter 241 is arranged on the side of the cold rivet head 242 away from the workpiece 7 and is connected to the cold rivet head 242. The size of the adapter 241 is larger than the diameter of the mounting hole, so that the cold rivet head 242 can be fixed to the second connecting plate 23.

[0061] like Figure 5 As shown, in one possible embodiment, the cold rivet head 242 has a groove 242a on one side close to the turntable 3. The inner wall of the groove 242a is concave in a direction away from the workpiece 7, which can shape the workpiece 7 after contact with the heated and softened workpiece 7, for example, the workpiece 7 can be formed into the round head of a rivet, thereby improving the stability of the riveting.

[0062] In one possible embodiment, a single heating module 1 can be provided with multiple hot air guns 14, and correspondingly, a single cold riveting module 2 can be provided with multiple cold riveting columns 24, thereby enabling simultaneous riveting at multiple different locations on the workpiece 7. The relative positions of the multiple hot air guns 14 can be set according to the relative positions of the riveting points required on the workpiece 7, and the relative positions of the multiple cold riveting columns 24 can be set similarly, thereby meeting more processing requirements and improving processing efficiency.

[0063] like Figure 6 As shown, in one possible embodiment, the riveting device includes a rotary drive member 6, which is mounted on the base plate 4 and is used to drive the turntable 3 to rotate. The rotary drive member 6 can be a motor or a cylinder, which is used to drive the turntable 3 to rotate, so that the workpiece 7 mounted on the mounting seat 31 can rotate with the turntable 3 to be heated and riveted in sequence. The turntable 3 can be rotatably mounted on the base plate 4, or the turntable 3 can be directly mounted on the rotary drive member 6. The cold riveting module 2 can be mounted on the base plate 4, and the heating module 1 and the cold riveting module 2 are arranged on the base plate 4 along the circumference of the turntable 3.

[0064] The above describes in detail the structure, features and effects of the present application based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present application, but the present application does not limit the scope of implementation to what is shown in the drawings.
