[0037] like Figure 1-5 As shown, this embodiment provides a multi-point solenoid valve riveting device, which is used for riveting a workpiece 10 pre-installed with a solenoid valve 11, including a mounting table 1 and a frame 2 arranged on the mounting table, a press assembly 7 is longitudinally installed on the frame 2, and also includes a riveting head assembly 3 for auxiliary riveting, which includes a head seat 31, and the head seat 31 is provided with a plurality of cylindrical holes 33 corresponding to the solenoid valve 11, and a riveting head 32 is slidably arranged in the cylindrical hole 33; a clamping assembly 4 is installed on the frame 2, and moves up and down to place and clamp the riveting head assembly 3 on the top of the workpiece 10; a moving assembly 5 is installed on the mounting table 1 and is located below the frame 2, driving the workpiece 10 to move on a horizontal plane.

[0038] By setting the riveting head assembly 3 corresponding to the workpiece 10, and setting the riveting heads 32 in the head seat 31 according to the solenoid valve 11 on the workpiece 10, the function of quickly positioning the riveting head 32 and the solenoid valve 11 is achieved, and multiple pre-installed solenoid valves 11 can be riveted at one time, thereby improving production efficiency.

[0039] like Figure 2 , 3 As shown, the pressure head seat 31 includes a seat body 311, a seat cover 312 and a seat bottom 313. The upper end of the riveting pressure head 32 extends out of the seat cover 312, and the portion located inside the seat cover 312 is installed with a first limit block 321 that abuts against the bottom surface of the seat cover 312. A limit step 331 is provided in the middle of the cylindrical hole 33 of the seat body 311, and a first elastic member 34 abuts between the limit step 331 and the first limit block 321. A second limit block 322 is installed inside the riveting pressure head 32, and a limit column 35 is slidably provided between the second limit block 322 and the riveting pressure head 32, and a second elastic member 36 abuts against the riveting pressure head 32 at the top of the limit column 35.
