When placing the lock head gasket, the side walls on the two sides of the accommodating groove 144 in the lock head gasket need to be placed above the grooves on the two sides of the protrusion 2072. When riveting, the steel wire rope 12 will be accommodated in the accommodating groove 144, at which time the side walls of the accommodating groove 144 will be pressed into the grooves on the two sides of the protrusion 2072, so that the end of the side wall will be bent inward, so that the steel wire rope 12 can be fixed with the lock head gasket 14.

[0032] Further, the fixing bottom plate 201 is also fixedly provided with a placing base 209 for placing a safety belt lock and a fixing device 208 for pressing and fixing the safety belt lock. The placing base 209 has a groove matched with the safety belt lock, after being placed, the fixing device 208 can fix it in the placing base 209, avoiding the safety belt lock from moving around during riveting.

[0033] Further, the fixing device 208 is a rotary clamping air cylinder.

[0034] Further, the other side of the fixed base plate 201 is fixedly connected with the first base plate 211 through the first guide column 215, the first guide column 215 is sleeved with the second base plate 212; the second base plate 212 is provided with the second guide column 216 between the first base plate 211; the second guide column 216 is fixed with the first base plate 211, and the second base plate 212 can move up and down along the second guide column 216.

[0035] The third guide column 210 is fixed on the second base plate 212, and the other end of the third guide column 210 is in contact with the lower riveting head 206 through the fixed base plate 201.

[0036] When riveting, the lower riveting head 206 needs to have a space for downward displacement, the lower riveting head 206 will press downward on the third guide column 210, and the third guide column 210 is fixed with the second base plate 212, so that the second base plate 212 is displaced downward, and the spring 214 below the second base plate 212 has a space for downward displacement. After the riveting is finished, the spring 214 resets the lower riveting head.

[0037] Further, the fixed base plate 201 is further provided with the second cylinder 217, the second cylinder 217 is connected with the placing base 209, and the placing base 209 is close to and away from the fixed seat 218. Specifically, a circular rod is connected, and the circular rod passes through the second through hole 2182 in the fixed seat 218.

[0038] When the lock head gasket riveting machine works, the second cylinder 217 pushes the placing base 209 away from the fixed seat 218, the roller 13 of the safety belt lock buckle is placed in the groove of the placing base 209, the second cylinder 217 pulls the placing base 209 back again, and the rotary clamping cylinder is controlled to be fixed. The steel wire rope 12 is placed above the protrusion 2072. The first cylinder 202 on both sides of the fixed base plate 201 works, drives the steel wire rope pressing piece 205 to press the steel wire rope 12 inward, and facilitates the placement of the lock head gasket 14. When the steel wire rope pressing piece 205 moves to the set position, the lock head gasket 14 is placed at the position of the steel wire rope, and the two first positioning protrusions 2062 are inserted into the two first positioning holes 142 in the lock head gasket, and the two second empty protrusions 2063 are inserted into the two second positioning holes 143 in the lock head gasket. The side walls on both sides of the containing groove 144 are inserted into the notch part 2031.
