Specific embodiment
The embodiment of the present invention: a kind of tensioning of belt wheel and quick replacement device, as shown in the picture, including rack 1, in rack
Machine 7 is arranged in 1 top, guide rail 13 is arranged in 1 lower part two sides of rack, electric machine support 4 is across on guide rail 13 and the electric machine support 4
It can be moved along guide rail 13, motor 5 is fixed on electric machine support 4 and connects machine 7 by belt 6, sets immediately below electric machine support 4
Screw rod 3 is set, electric machine support nut 14 is set in 4 bottom surface of electric machine support, screw rod 3 passes through electric machine support nut 14 and passes through
Thread connecting mode realizes that 3 driving motor bracket 4 of screw rod is mobile, which is placed in rack 1, and in screw rod 3 and machine
Bearing 2 is arranged in 1 junction of frame.
Handwheel 9 wherein is set in 3 front end of screw rod and the handwheel is located at outside rack 1, is fixed with screw rod tooth in 3 front of screw rod
Wheel 8, the setting locking control shaft 11 in the rack 1 of 3 side of screw rod, in the working end fixed setting locking control of locking control shaft 11
