Abstract
The invention discloses a diamond roller dismounting device which comprises a base. The diamond roller dismounting device further comprises a screw shaft, a sleeve and a force application mechanism. The screw shaft is vertically arranged on the base and is used for penetrating through an inner ring hole of a diamond roller and a shaft hole of a cutter bar and guiding dismounting of the diamond roller and the cutter bar. The sleeve is arranged outside the cutter bar in a sleeving mode and abuts against the bottom of the diamond roller so as to support the diamond roller from the bottom and make the cutter bar suspended. The force application mechanism is arranged outside the screw shaft in a sleeving mode and covers the upper end of the cutter bar in a pressing mode so as to apply downward pressure to the cutter bar. The sleeve is arranged on the base. The sleeve supports the bottom of the diamond roller and makes the cutter bar suspended, and the force application mechanism is adopted for applying downward action force to the top end of the cutter bar, so that the cutter bar is forced to be disengaged from the inner ring hole of the diamond roller, and the diamond roller is dismounted. The action force is prevented from being directly acted on the diamond roller, and therefore the phenomenon that the diamond roller deforms due to stress is avoided.
