The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further elaborated, should be noted that following explanation is only in order to explain the utility model, is not limited its content.
The utility model is a kind of blower fan main drive chain completion assembly tooling, and blower fan comprises complete machine 7 and the main drive chain that mainframe 6 is installed, and main drive chain comprises gear-box 8 and bearing chamber 9; The utility model comprises upper support face 1 and for supporting some row's supporting legs 2 of upper support face 1, same row's supporting leg 2 is highly consistent, height along the longitudinal bracing leg 2 of upper support face 1 becomes large gradually, so that be 3 ° ~ 5 ° angles between upper support face 1 and horizontal plane, the end that upper support face 1 is lower also is provided with front apron 3.The square tube that upper support face 1 is some mutual square crossings, and agree with fully with transportation underframe 5.Supporting leg 2 adopts the H shaped steel, and lower end is welded with flat board, supports steadily firmly.The channel-section steel that front apron 3 is outward opening.
A kind of blower fan main drive chain completion assembly method, step is as follows:
