The spring is in a compressed state, shown as compression spring 56 (shown in FIG. 10), after the power compartment floor is installed, at which time the dowel pin lift pin 55 is withdrawn from the through hole of the floor mounting cap 46 into the third cavity. And a bottom plate limit stop 48 is arranged at one side of the bottom plate fixing seat 47 at intervals and used for limiting a power compartment bottom plate 52.
The working principle and the operation steps of the power cabin bottom plate mounting jig of the invention are further described as follows:
installing a power cabin bottom plate:
the power cabin bottom plate 52 is vertically placed, a bottom plate bearing 59 of the power cabin bottom plate 52 is sleeved into a positioning pin ejector rod 55, the power cabin bottom plate 52 is limited through a bottom plate limit stop 48, the upper end of a jig is installed on the power cabin bottom plate, the end part 63 of a transmission shaft of the water-jet propeller 7 is pre-installed into the bottom plate bearing 59 of the power cabin bottom plate 52, a hoop seat 33 and a hoop cover 54 are fixed on the upper end of the water-jet propeller 7 through a hoop buckle 34, a third hand wheel 37 is rotated to push a third lead screw sliding block 40, so that a third sliding block ejector rod 42 is pushed to push against a water-jet propulsion bearing end surface 60, the spring is further compressed and retreated to the bottom of a third cavity through further rotating the third hand wheel 37, the assembly of the water-jet propeller 7 and the power cabin bottom plate 52 is realized, and finally the water-jet propulsion fixing flange 51 is completely contacted with the power cabin bottom plate 52, and the installation is completed.
As mentioned above, the two sets of mounting jigs are respectively used for mounting the transmission shaft of the water jet propeller and the transmission shaft and the power cabin bottom plate; the two sets of mounting fixtures can be used separately or in combination. When the installation jig is used, the 2 installation jigs can be combined together for use, the water jet propeller and the transmission shaft are installed by using the first set of surfboard water jet propeller installation jig, and then the transmission shaft and the power cabin bottom plate are installed by using the second set of surfboard power cabin bottom plate water jet propulsion installation jig, so that the installation of the transmission shaft and the power cabin bottom plate is realized. Specifically, after the water jet propeller and the transmission shaft are installed by using the first set of surfboard water jet propeller installation jig, the first hand wheel 2 needs to be rotated in the opposite direction, and the hand wheel drives the first screw rod 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 move outwards, and pressing force of the first sliding block ejector rod (6) on the water jet propeller (7) is released. Then, the second hand wheel 13 is rotated in the opposite direction, the second screw threads 11 are also rotated synchronously, the second screw slide block 10 is driven to move outwards, the other end of the transmission shaft 8 is moved out of the cavity of the second slide block 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 water jet propeller can be taken down from the tool.
Finally, it should be noted that: 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 or portions thereof without departing from the spirit and scope of the invention.
