Pin shaft dismounting machine and pin shaft dismounting equipment

The invention discloses a pin shaft dismounting machine which comprises an impact hammer; the driving seat is in sliding connection with the impact hammer in the shaft pulling direction and abuts against an impact head of the impact hammer so as to bear impact force of the impact hammer in the shaft pulling direction; the joint block is used for being fixedly connected with a pin shaft to be pulled and is mounted on the driving seat; the driving mechanism is used for driving the impact hammer to move in the shaft pulling direction. In the pin shaft dismounting machine, the impact hammer and the driving seat which are in sliding connection are adopted, so that the driving seat can better bear impact force from the impact hammer, compared with inertia impulse caused by direct driving and impact force, the pin shaft to be pulled can bear very large impact force, and a very good pin pulling effect can be achieved. And the driving mechanism can simultaneously drive the pin shaft to be pulled to move along the shaf
