During riveting, the seat belt buckle is fixed on the riveting positioning device, and the lock gasket 14 is placed in a suitable position, and the upper riveting device moves downward, thereby fixing the lock gasket 14 and the wire rope 12.

[0034] like Figure 4 and Figure 5The riveting and positioning device shown in different angles. The riveting and positioning device includes a fixed base plate 201; two linear guide rails 204 are fixedly arranged on one side surface of the fixed base plate 201, and the first cylinder 202 is fixedly arranged at both ends; the output end of the first cylinder 202 is fixedly connected to a wire rope pressing piece 203, and the wire rope pressing piece 203 slides along the linear guide rail 204; the wire rope pressing piece 203 includes a notch 2031 arranged at the end thereof. Specifically, the wire rope pressing piece 203 is fixed to the guide rail slider 205. The guide rail slider 205 is connected to the linear guide rail and can slide on the linear guide rail 204. The piston rod at the output end of the first cylinder 202 is fixedly connected to the wire rope pressing piece 203. When the wire rope pressing member 203 is needed to press the wire rope, the piston rod moves the wire rope pressing member 203 to the position where the wire rope is placed, so that the wire rope 12 is bent, which is convenient for the placement of the lock gasket 14.

[0035] like Figure 6 The end of the wire rope pressing member 203 is provided with a notch portion 2031 , and the proximal end of the other end is provided with a pressing member connecting groove 2032 for connecting with the piston rod of the first cylinder 202 .

[0036] A step-shaped fixing seat 218 is disposed between the two linear guide rails 204. A first through hole 2181 is disposed on the fixing seat 218. A lower riveting head 206 that can move up and down is disposed in the first through hole 2181. A wire rope support plate 207 is fixedly disposed on the step plane of the fixing seat 218. Figure 7 In the fixing seat 218 shown, one side of the first through hole 2181 is arc-shaped, and the other end is flat, and the flat side extends to a step-shaped portion.

[0037] like Figure 8 The lower riveting head 206 shown includes a lower riveting head body 2061, two first positioning protrusions 2062 and two second positioning protrusions 2063; the two first positioning protrusions 2062 match the two first positioning holes 142 in the lock washer, and the two second positioning protrusions 2063 match the two second positioning holes 143 in the lock washer. Further, the first positioning protrusion 2062 is cylindrical, and the cross-section of the second positioning protrusion 2063 is generally waist-shaped.

[0038] like Fig. 9As shown, the wire rope support plate 207 includes a support plate body 2071, and a trapezoidal protrusion 2072 arranged on the support plate body 2071; first protrusions 2074 are arranged on both sides of the protrusion 2072. The protrusion 2072 matches the open end of the receiving groove 144. Both sides of the protrusion 2072 are grooves. When placing the lock gasket, the side walls on both sides of the receiving groove 144 in the lock gasket need to be located above the grooves on both sides of the protrusion 2072. During riveting, the wire rope 12 will be accommodated in the receiving groove 144, and at this time, the side walls of the receiving groove 144 will be pressed into the grooves on both sides of the protrusion 2072, so that the ends of the side walls will bend inward, so that the wire rope 12 can be fixed to the lock gasket 14.

[0039] The lower riveting head body 2061 is formed with one side being planar and the other side being arc-shaped. When placed in the first through hole 2181, the planar side of the lower riveting head body 2061 is embedded in the recessed portion 2073 of the wire rope support plate 207, so that the lower riveting head, the wire rope support plate 207 and the fixing seat 218 can be fixed and limited, making it difficult to shift.

[0040] like Fig.10 and Fig.11 As shown, the upper riveting device includes a riveting power device 101 and an upper riveting head 102; the upper riveting head 102 includes an upper riveting head body 1021, and two protrusions 1022 are provided on the upper riveting head body 1021. The riveting power device 101 provides power for riveting, and can be specifically a cylinder or a hydraulic cylinder, so that the upper riveting head 102 moves downward to achieve riveting. The two protrusions 1022 on the upper riveting head 102 are inserted into the notch 2031 during riveting.

[0041] Furthermore, a placement base 209 for placing the seat belt buckle and a fixing device 208 for pressing and fixing the seat belt buckle are also fixedly arranged on the fixed base plate 201. The placement base 209 has a groove matching the seat belt buckle, and after the seat belt buckle is placed, the fixing device 208 can fix it in the placement base 209 to prevent the seat belt buckle from moving during riveting.

[0042] Furthermore, the fixing device 208 is a rotary clamping cylinder.

[0043] Furthermore, the other side of the fixed base plate 201 is fixedly connected to the first base plate 211 via a first guide column 215, and the first guide column 215 is sleeved with a second base plate 212; a second guide column 216 is arranged between the second base plate 212 and the first base plate 211; the second guide column 216 is fixed to the first base plate 211, and the second base plate 212 can move up and down along the second guide column 216.

[0044] A third guide post 210 is fixed on the second bottom plate 212, and the other end of the third guide post 210 passes through the fixed bottom plate 201 and contacts the lower riveting head 206. A third bottom plate 213 is fixedly disposed on a surface of the first bottom plate 211 close to the second bottom plate 212, and a groove for supporting a spring 214 is disposed on the third bottom plate 213, and the other end of the spring 214 is fixed to the second bottom plate 212.

[0045] When the upper riveting head 102 is pressed downward, the lower riveting head 206 needs to have space to move downward, and the lower riveting head 206 will press the third guide column 210 downward, and the third guide column 210 is fixed to the second bottom plate 212, so that the second bottom plate 212 moves downward, and the spring 214 under the second bottom plate 212 has space to move downward. After the riveting is finished, the spring 214 will reset the lower riveting head.

[0046] Furthermore, a second cylinder 217 is fixedly arranged on the fixed base plate 201, and the second cylinder 217 is connected to the placement base 209, and is used to place the base 209 close to and away from the fixed base 218. Specifically, they are connected by a circular rod, and the circular rod passes through the second through hole 2182 in the fixed base 218.

[0047] Furthermore, the output end of the riveting power device 101 is fixed to the upper riveting head 102 through a fixing plate 103; the fixing plate 103 can move up and down along the upper riveting guide column 104. The upper riveting head 102 is fixedly connected to the fixing plate 103 through an upper riveting head connecting rod 105 and an upper riveting head connecting plate 106.

[0048] When the lock gasket riveting machine of the present invention is working, the second cylinder 217 pushes the placement base 209 away from the fixed base 218, and places the roller 13 of the safety belt buckle in the groove of the placement base 209. The second cylinder 217 then pulls the placement base 209 back and controls the rotating clamping cylinder to fix it. The steel wire rope 12 is placed above the protrusion 2072. The first cylinders 202 on both sides of the fixed base plate 201 work, driving the steel wire rope pressing piece 203 to press the steel wire rope 12 inward, which is convenient for the placement of the lock gasket 14.

[0049] When the wire rope pressing member 203 moves to the set position, the lock gasket 14 is placed at the position of the wire rope, and the two first positioning protrusions 2062 are inserted into the two first positioning holes 142 in the lock gasket, and the two second positioning protrusions 2063 are inserted into the two second positioning holes 143 in the lock gasket. The side walls of the receiving groove 144 are inserted into the notch 2031. The upper riveting head 102 is moved downward, and when it contacts the lock gasket 14, the two protrusions 1022 are inserted into the notch 2031 during riveting, and the pressure continues to be pressed downward, while the lower riveting head 206 moves downward, so that the lock gasket 14 is riveted and fixed to the wire rope.

[0050] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work.
