The invention provided a riveting machine. The riveting machine comprises a rack, a conveying mechanism and a plurality of compressing devices, and further comprises a chamfering device, a heating device, an end cover feeding device, an end cover discharging device and a riveting mechanism which are arranged sequentially in the conveying direction of the conveying mechanism. The conveying mechanism is mounted on the rack, and the multiple compressing devices are sequentially mounted on the conveying mechanism at intervals and used for clamping a to-be-riveted guiding flexible shaft. The chamfering device is used for chamfering the guiding flexible shaft clamped by the compressing devices; the heating device is used for heating the chamfered end of the guiding flexible shaft; the end coverfeeding device is used for conveying a to-be-riveted end cover to the end cover discharging device; the end cover discharging device conveys the to-be-riveted end cover to the riveting mechanism; andthe riveting mechanism rivets the to-be-riveted end cover to the chamfered end of the guiding flexible shaft. Compared with the prior art, the riveting machine provided by the invention is high in automation degree and high in riveting efficiency when conducting riveting operation of the guiding flexible shaft and the end cover.
