DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1-4As shown, a hot rivet installation device includes a fixed bracket 1, a hydraulic cylinder 2 and a clamping mechanism 3. A base 16 is arranged at the bottom of the fixed bracket 1. The hydraulic cylinder 2 is connected to a hydraulic station 15. A hydraulic cylinder installation platform 4 and a workpiece reserved groove 5 which are recessed downward are arranged in the middle of the fixed bracket 1. The hydraulic cylinder 2 is arranged on the hydraulic cylinder installation platform 4. The clamping mechanism 3 includes a vertical rod 6 and a clamp arranged on the vertical rod 6. The clamp includes a fixing plate 7, a clamping plate 8 and a connecting rod 9. The vertical rod 6 is arranged on the fixed bracket 1. A through hole 10 is penetrated at the top of the vertical rod 6. The connecting rod 9 is penetrated in the through hole 10. Inside, the connecting rod 9 is parallel to the protruding end of the hydraulic cylinder 2, the connecting rod 9 is fixedly connected to the end face of the fixed plate 7, the clamping plate 8 is radially arranged on the outer periphery of the fixed plate 7 in a cross shape, the clamping plate 8 is perpendicular to the connecting rod 9, and the clamping plate 9 is provided with a screw hole 11 matching the hot riveting workpiece, and a rivet jig 12 is correspondingly arranged on the end wall of the protruding end of the hydraulic cylinder 2 and the workpiece reserved groove 5 away from the hydraulic cylinder mounting platform 4.
