installing a power cabin bottom plate:
the power cabin bottom plate 52 is vertically placed, the bottom plate bearing 59 of the power cabin bottom plate 52 is sleeved into the positioning pin ejector rod 55, the limiting of the power cabin bottom plate 52 is achieved through the bottom plate limiting stop 48, the transmission shaft end 63 of the water jet propeller 7 is preloaded into the bottom plate bearing 59 of the power cabin bottom plate 52 at the upper end of the power cabin bottom plate installation jig, the upper end of the water jet propeller 7 is fixed through the hoop seat 33 and the hoop cover 54 through the hoop buckle 34, the third screw rod sliding block 40 is pushed through rotating the third hand wheel 37, the third sliding block ejector rod 42 is pushed to bear against the water jet propulsion bearing end face 60, the spring is further compressed and retreated to the bottom of the third cavity through further rotating the third hand wheel 37, the water jet propeller 7 and the power cabin bottom plate 52 are assembled, and finally the water jet propulsion fixing flange 51 and the power cabin bottom plate 52 are completely contacted, and the installation is completed.
As described above, the invention respectively realizes the installation of the transmission shaft of the water spraying propeller and the installation of the transmission shaft and the power cabin bottom plate through the two sets of installation jigs; the two sets of mounting jigs can be used separately or in combination. When the installation jig is used, the 2 installation jigs can be combined together, the first set of surfing board water spraying propeller installation jigs are used for installing the water spraying propeller and the transmission shaft, and then the second set of surfing board power cabin bottom plate water spraying propulsion installation jigs are used for installing the transmission shaft and the power cabin bottom plate. Specifically, after the first set of surfboard water spray propeller mounting jig is used for mounting the water spray propeller and the transmission shaft, the first hand wheel 2 is required to be rotated reversely, and the hand wheel drives the first screw rod screw thread (4) to synchronously rotate, so that the first screw rod sliding block (5) and the first sliding block ejector rod (6) are driven to outwards move, and the pressing force of the first sliding block ejector rod (6) on the water spray propulsion (7) is relieved. Then, the second hand wheel 13 is rotated in the opposite direction, the second screw threads 11 are synchronously rotated to drive the second screw slider 10 to move outwards, the other end of the transmission shaft 8 is moved out of the cavity of the second slider ejector rod 9, the fixation of one end of the transmission shaft is released, one end of the transmission shaft can be staggered with the second screw threads 11, and the assembled transmission shaft and the water jet propeller can move along the direction of the second hand wheel 13, so that the assembled transmission shaft and the assembled water jet propeller are taken down from the tool.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
