Abstract
The invention discloses a propeller balance tool. The propeller balance tool is used for fixing a propeller when static balance of the propeller is adjusted and comprises a first core shaft, a second core shaft and a guide frame, wherein the first core shaft and the second core shaft are used for fixing the two ends of the propeller respectively, and the guide frame is arranged between the propeller and the second core shaft in a clamping mode. The first core shaft is provided with a first fixing end used for being connected with the propeller and is coaxially arranged with the second core shaft. The second core shaft is provided with a second fixing end used for being connected with the propeller. The first fixing end is detachably provided with a first flange, the second fixing end is detachably provided with a second flange, and the first flange and the second flange are respectively provided with a connection portion used for being connected with the propeller and locating the propeller. According to the propeller balance tool, just the flanges need to be replaced for different propellers, use of the tool is convenient, and the production cost is saved at the same time.
Description
Technical field
the present invention relates to ship propellers manufacture field, particularly a kind of propeller balance frock.
Background technology
static balance is a critical process manufacturing adjustable pitch propeller, and ordinary circumstance is that blade is installed on propeller hub body, by frock body, at blade, in positive truck position, reaches balance requirement, and the quality of static balance frock has thus determined quality and the efficiency of balance.
existing static balancing apparatus adopts by frock as shown in Figure 2, and this frock adopts two plugs to be fixed on the two ends with screw, and is maked somebody a mere figurehead, and carrys out adjustment; But whether pitch will lean on the precision of frock to guarantee in real positive truck position; Plug two ends need to be according to concrete Design of Propeller manufacture in addition, can not general different screw, and the utilization rate of so greatly having wasted material, production cost is higher.
Summary of the invention
the object of this invention is to provide a kind of easy to use and can be for the balance tooling of different screws.
for achieving the above object, the technical solution used in the present invention is:
propeller balance frock, for fixing described screw in the time of the static balance of propeller blades, it comprises the first mandrel and the second mandrel that is respectively used to fixing described screw two ends, be fastened on the saddle between described screw and described the second mandrel, described the first mandrel has for connecting the first stiff end of described screw, described the first mandrel and described the second mandrel coaxially arrange, described the second mandrel has for connecting the second stiff end of described screw, on described the first stiff end, be detachably provided with the first flange, on described the second stiff end, be detachably provided with the second flange, described the first flange, described the second flange is respectively arranged with for connecting and locate the connecting portion of described screw.
preferably, described the second mandrel has the through hole arranging along its axis direction, in described through hole, be provided with adjusting rod, described adjusting rod one end and described saddle removably connect, and the other end is provided with the adjusting device that adjustable described adjusting rod stretches out the distance of described through hole.
preferably, described adjusting device is adjusting screw(rod).
because technique scheme is used, the present invention compared with prior art has following advantages:
because the present invention had once added flange at the first mandrel and the second mandrel with screw junction, can only need to change flange for different screws, facilitated the use of frock, saved production cost simultaneously.
Accompanying drawing explanation
accompanying drawing 1 is schematic diagram of the present invention;
accompanying drawing 2 is existing frock schematic diagram.
in above accompanying drawing: 1, screw; 2, the first mandrel; 3, the second mandrel; 4, saddle; 5, the first flange; 6, the second flange; 7, adjusting rod; 8, adjusting screw(rod).
The specific embodiment
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment mono-: shown in accompanying drawing 1, propeller balance frock, for fixing screw 1 in the time of the static balance of propeller blades 1, it comprises and is respectively used to fixedly the first mandrel 2 and second mandrel 3 at screw 1 two ends, be fastened on the saddle 4 between screw 1 and the second mandrel 3, the first mandrel 2 has for connecting the first stiff end of screw 1, the first mandrel 2 and the second mandrel 3 coaxially arrange, the second mandrel 3 has for connecting the second stiff end 5 of screw 1, on the first stiff end, be detachably provided with the first flange 5, on the second stiff end, be detachably provided with the second flange 6, the first flange 5, the second flange 6 is respectively arranged with for connecting the also connecting portion of setting screw oar 1.
the second mandrel 3 has the through hole arranging along its axis direction, is provided with adjusting rod 7 in through hole, and adjusting rod 7 one ends and saddle 4 removably connect, and the other end is provided with the adjusting device that adjustable adjusting rod 7 stretches out the distance of through hole.
adjusting device is adjusting screw(rod) 8.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
