[0031] Specifically, the first pressing member 100 is used to press against one end of the rivet barrel 1. The end surface of the first pressing member 100 is provided with an annular first groove 110, and the cross section of the first groove 110 is arc-shaped. When the first groove 110 abuts against the end of the rivet barrel 1, under the guidance of the first groove 110, the end of the rivet barrel 1 can gradually turn outward. The second pressing member 200 is used to press against the other end of the rivet barrel 1. The end surface of the second pressing member 200 is provided with an annular second groove 210, and the cross section of the second groove 210 is arc-shaped. When the second groove 210 abuts against the end of the rivet barrel 1, under the guidance of the second groove 210, the end of the rivet barrel 1 can gradually turn outward. The connecting driving structure 300 is used to connect the first pressing member 100 and the second pressing member 200, and can drive the first pressing member 100 and the second pressing member 200 to gradually move closer to or away from each other.

[0032] When in use, first insert the rivet barrel 1 into the rivet holes of the two parts that need to be riveted, then buckle the first groove 110 on the first tightening member 100 onto one end of the rivet barrel 1, then press the second groove 210 on the second tightening member 200 onto the other end of the rivet barrel 1, then connect the first tightening member 100 and the second tightening member 200 through the connecting driving structure 300, and drive the first tightening member 100 and the second tightening member 200 to gradually approach each other through the connecting driving structure 300. Under the guidance of the first groove 110 and the second groove 210, in the process of the first tightening member 100 and the second tightening member 200 approaching each other, the two ends of the rivet barrel 1 gradually turn outward until they are inverted on the surfaces of the two parts.

[0033] By adopting this device, the hollow rivet tube 1 can be smoothly riveted to the parts. At the same time, under the guidance of the first groove 110 and the second groove 210, the flange of the rivet is not easy to crack or deform, thereby improving the firmness and appearance of the riveting.

[0034] In this embodiment, the first tightening member 100 is a hollow rod, and an internal thread is arranged in the first tightening member 100. The connecting driving structure 300 includes a screw rod 310, and the screw rod 310 is fixed on the second tightening member 200 and is coaxially arranged with the second groove 210. The screw rod 310 can pass through the rivet tube 1 and be inserted into the first tightening member 100 to be connected with the internal thread.

[0035] When in use, the screw rod 310 is passed through the rivet barrel 1 and inserted into the first pressing member 100 to connect with the internal thread, and the screw rod 310 is rotated to drive the first pressing member 100 and the second pressing member 200 to move closer to or away from each other. Of course, in other embodiments, the connection driving structure 300 can also be other structural forms, such as the operator holding the first pressing member 100 and the second pressing member 200 with both hands respectively, and then pressing the first pressing member 100 and the second pressing member 200 against each other, which can also drive the first pressing member 100 and the second pressing member 200 to move closer to each other.

[0036] As a preferred embodiment, the first tightening member 100 also includes a guide sleeve 120, which is coaxially arranged with the first groove 110 at the end of the first tightening member 100. The outer diameter of the guide sleeve 120 is adapted to the inner diameter of the rivet barrel 1 and can be slidably inserted into the rivet barrel 1, and the screw 310 can penetrate the guide sleeve 120.

[0037] The guide sleeve 120 can be used to facilitate the insertion of the screw rod 310 into the first tightening member 100 . Meanwhile, the guide sleeve 120 can prevent the end of the rivet barrel 1 from turning inward, thereby further improving the flanging quality.

[0038] In this embodiment, the second pressing member 200 includes a second pressing rod 220 and a rotational power source 320. The second pressing rod 220 is a hollow rod, the second groove 210 is provided on the end surface of the second pressing rod 220 close to the first pressing member 100, the screw rod 310 can slide through the second pressing rod 220 and connect with the rotational power source 320, and the rotational power source 320 can drive the screw rod 310 to rotate.

[0039] By driving the screw rod 310 to rotate through the rotary power source 320 , the first pressing member 100 and the second pressing member 200 can move relative to each other or move in opposite directions.

[0040] Specifically, the rotary power source 320 includes a mounting plate 321, a driving gear 322, a handle 323 and a driven gear 324. The mounting plate 321 is rotatably connected to the second pressure rod 220, a through hole is provided on the mounting plate 321, and the driven gear 324 is sleeved and fixed on the end of the screw rod 310 passing through the through hole, the driving gear 322 is rotatably mounted on the mounting plate 321, and meshes with the driven gear 324, and the transmission ratio between the driving gear 322 and the driven gear 324 is less than 1, and the handle 323 is mounted on the driving gear 322.

[0041] When in use, the handle 323 can be held by hand to rotate the driving gear 322, and the driving gear 322 drives the driven gear 324 to rotate, which can drive the screw rod 310 to rotate. Since the transmission ratio between the driving gear 322 and the driven gear 324 is less than 1, the screw rod 310 can be driven to accelerate the movement, thereby improving the installation efficiency.

[0042] In addition, a ball bearing may be disposed between the contact surface of the mounting plate 321 and the second pressing rod 220 to reduce the friction between the mounting plate 321 and the second pressing rod 220 .

[0043] As another preferred embodiment, the first pressing member 100 includes a first push rod 130 and a first pressure rod 140. The first push rod 130 and the first pressure rod 140 are coaxially and rotatably connected, the first groove 110 is provided on the first pressure rod 140, the internal thread is provided in the first push rod 130, and the screw rod 310 can slide through the first pressure rod 140 and be threadedly connected with the first push rod 130. Similarly, a ball bearing can be provided between the first push rod 130 and the first pressure rod 140.

[0044] When the screw rod 310 rotates and drives the first push rod 130 to approach the second pressing member 200, the rivet barrel 1 can be pressed by the first pressing rod 140, thereby facilitating the first pressing rod 140 to press the rivet barrel 1.

[0045] The above rivet assembly installation device is used as follows:

[0046] When in use, first insert the rivet barrel 1 between the two parts that need to be riveted, then insert the guide sleeve 120 into the rivet barrel 1, then insert the screw rod 310 into the first push rod 130 and connect it with the internal thread, then fix the first push rod 130, and rotate the driving gear 322 through the handle 323 to drive the first tightening member 100 and the second tightening member 200 to move closer to each other until the first groove 110 and the second groove 210 press the two ends of the rivet barrel 1 together. After the flanging is completed, the driving gear 322 can be rotated in the opposite direction, the screw rod 310 can be withdrawn, and then the guide sleeve 120 can be pulled out.

[0047] By adopting this device, the hollow rivet tube 1 can be smoothly riveted to the part. At the same time, under the guidance of the first groove 110 and the second groove 210, the flange of the rivet is not easy to crack or deform, thereby improving the installation firmness and appearance of the part.

[0048] In addition, by setting the first pressing rod 140 and the second pressing rod 220, the rotational friction between the first pressing member 100 and the second pressing member 200 and the rivet barrel 1 can be changed into direct pressing, which can reduce the friction between the first pressing member 100 and the second pressing member 200 and the rivet barrel 1 and prevent the surface of the rivet barrel 1 from being worn, thereby improving the appearance quality of the entire component. In addition, by the cooperation of the driving gear 322 and the driven gear 324, the riveting can be completed conveniently.
