Description

Positioning tool for manufacturing of propeller and variable-pitch propeller handle

Technical Field

The utility model belongs to the technical field of the aerial variable pitch screw of threaded connection type combined material and specifically relates to a location frock is made in production of screw and variable pitch oar handle.

Background

The composite material propeller needs to be manufactured in a mold in the production and manufacturing process, and the threaded metal protection handle cannot reasonably determine the angle positioning in the mold, so that the angle of the propeller blade is uncertain in the screwing process. Thereby the influence is used, the utility model discloses a frock rack processes out the setpoint of assigned position and angle on screw thread type metal protection handle shell, lets screw thread type metal protection handle have better location in the mould. Thereby the paddle angle is more accurate and the use is more convenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a location frock is made in the production of screw and displacement oar handle to the defect that prior art exists, and the location is firm rapidly, ensures to process unanimously. The problem of take screw thread type oar handle can't carry out angle location through ordinary clamping mode is solved.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a production, manufacturing and positioning tool for a propeller and a variable-pitch propeller handle comprises a tool body, wherein the tool body comprises a positioning bottom plate, a positioning cambered surface platform and a positioning screw sleeve;

the positioning cambered surface platform and the positioning screw sleeve are both arranged on the positioning bottom plate, and the axes of the positioning cambered surface platform and the positioning screw sleeve are consistent.

Furthermore, the positioning bottom plate, the positioning cambered surface table and the positioning thread sleeve are integrally formed.

Furthermore, the positioning screw sleeve with the necking arranged on the end face of the outer shaft of the positioning screw sleeve is close to the step for screwing and positioning the screw pitch-variable paddle handle.

Furthermore, a hollowed screwing observation window is formed in the circumferential surface of the positioning screw sleeve.

Furthermore, a positioning mounting hole is formed in the positioning bottom plate.

Compared with the prior art, the utility model following beneficial effect has:

the utility model discloses location frock has solved and has taken the unable problem that carries out angle location through ordinary clamping mode of screw thread type oar handle (because the screw thread is gone into angle decision paddle angle, the unable accurate positioning screw thread angle of ordinary clamping mode). The screw thread screwing connection is adopted, the paddle handle is installed in a screw sleeve of the tool, the positioning cambered surface platform is used for auxiliary positioning, the screwing degree of the screw thread is observed through the screwing observation window, and the consistency of the machining position is ensured. The bottom of the positioning screw sleeve is close to the step, and the tight step is taken as the angle determination of the paddle handle after the paddle handle is screwed. The positioning is rapid and firm, and the processing consistency is ensured.

The tool defines the screw thread entering angle in advance through a 3D printing mode. The screw thread paddle handle can only enter from one angle when entering, and the deep distance of the paddle handle is limited by the positioning screw sleeve close to the step through the limit point at the tail end of the tool. The key position of the paddle handle positioning hole needing to be processed of the paddle handle during production and manufacturing of the paddle is more accurately determined. Therefore, the paddle product corresponding to the working angle can be accurately produced.

Drawings

Fig. 1 is a schematic structural view of a positioning tool for manufacturing a propeller and a variable pitch propeller handle according to the present invention;

fig. 2 is a top view of fig. 1.

In the figure: a paddle handle positioning hole 1 to be processed; a screw thread pitch-variable type paddle handle 2; a positioning base plate 3; screwing the observation window 4; the positioning thread sleeve is tightly close to the step 5; positioning the cambered surface table 6; and a positioning screw sleeve 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution:

the utility model provides a location frock is made in production of screw and displacement oar handle, includes tool body 1, tool body outer wall surface can laminate 2 inner wall surfaces of the split duct body completely, and tool body and the split duct body still lock each other through locking mechanism simultaneously.

The screw thread screwing connection is adopted, the paddle handle is installed in a screw sleeve of the tool, the positioning cambered surface platform is used for auxiliary positioning, the screwing degree of the screw thread is observed through the screwing observation window, and the consistency of the machining position is ensured. The bottom of the positioning screw sleeve is close to the step, and the tight step is taken as the angle determination of the paddle handle after the paddle handle is screwed. The positioning is rapid and firm, and the processing consistency is ensured.

And after the paddle handle is positioned, machining and drilling are carried out on the designated position, namely the paddle handle positioning hole 1 needing to be machined.

High accuracy location frock is manufactured through 3D printing technique production. The thread cutting-in angle and the screwing-in position of the paddle handle are accurately designed. And designing an observation window at the corresponding position of the tool. And carrying out secondary correction. The paddle handle is ensured to be clamped at a designated working position. And processing the angle positioning hole according to a design drawing.

The utility model discloses location frock has solved and has taken the unable problem that carries out angle location through ordinary clamping mode of screw thread type oar handle (because the screw thread is gone into angle decision paddle angle, the unable accurate positioning screw thread angle of ordinary clamping mode). The frock is passed through the 3D and is printed the form and go on injecing in advance to the screw thread. The screw thread paddle handle can only enter from one angle when entering and passes through a limit point at the tail end of the tool. The positioning screw sleeve is close to the step 5 to limit the depth distance of the paddle handle. The key position of the paddle handle positioning hole 1 needing to be processed of the paddle handle during production and manufacturing of the paddle blade is more accurately determined. Therefore, the paddle product corresponding to the working angle can be accurately produced.
