detailed description

The technical scheme of the utility model is further illustrated below through specific examples.

As shown in Figure 1-2: the guide wheel quenching automatic turning device includes a left clamping turning mechanism and a right clamping turning mechanism arranged oppositely at intervals, and a hydraulic lift is arranged between the left holding turning mechanism and the right clamping turning mechanism Mechanism 7. The left clamping and turning mechanism includes a left support platform 2, a left cylinder 1 installed on the left support platform 2, and a worm gear box 5. The left cylinder 1 has a telescopic piston rod, and a section of the piston rod The external spline is connected with the worm gear in the worm gear box 5, and the front end of the piston rod is provided with a left clamping part 3; .

The right clamping and turning mechanism includes a right support platform 8 and a right cylinder 4 installed on the right support platform 8. The front end of the piston rod of the right cylinder 4 is provided with a right clamping part that is ejected and retracted with the piston rod. , A space for clamping and turning over the guide wheel 9 is formed between the left clamping part 3 and the right clamping part.
