The positioning pin on the blade positioning sleeve is adopted for positioning, the positioning accuracy is high, the twisting angle of the blade body can be accurately grasped, the blade quality is high, and the balance and the safety of the high-speed rotating blade are ensured.
Description
Technical Field
The invention belongs to the technical field of unmanned aerial vehicle blade manufacturing, and relates to a positioning mechanism of an unmanned aerial vehicle blade manufacturing mold.
Background
Unmanned aerial vehicles are a new industry and are widely used in military and civil fields. The blades of the unmanned aerial vehicle are main moving parts for meeting the power of the unmanned aerial vehicle. With the development of the aviation industry in China, the unmanned aerial vehicle becomes one of the novel development industries of the aviation industry. The unmanned aerial vehicle has the advantages that the required performance is high, the rotating speed is high, the blades are of the sheet structures, the length of each blade is about 1-3 meters generally, the twisting angle of the blade body of each blade is large, and the end face of the blade handle is provided with the eccentric positioning pin structure for adjusting the angle of each blade. The positioning pin and the positioning sleeve are integrally and mechanically molded, and the molding process is complex. The blade body of the blade is integrated with the blade handle into a whole when being molded by the blade body mold; during the mould shaping, the blade location adopts machining, and angular positioning deviation is great, and blade mould shaping relief angle error is big, will take the position sleeve of locating pin to fix to the petiole terminal surface again on, more be difficult to guarantee the installation angle uniformity of blade body and locating pin, and then lead to the blade locating pin poor with the uniformity of the angle of blade body, hardly guarantee high-speed rotating vane's equilibrium and security.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and provides a positioning mechanism of an unmanned aerial vehicle blade manufacturing mold, which adopts a positioning pin on a blade positioning sleeve for positioning, has high positioning accuracy, can more accurately grasp the twisting angle of a blade body, has high blade quality, and ensures the balance and safety of a high-speed rotating blade.
In order to achieve the purpose, the technical solution of the invention is as follows: a positioning mechanism of an unmanned aerial vehicle blade manufacturing mold comprises an upper mold and a lower mold; the lower die consists of a lower die block and a cutting block detachably fixed on the upper end surface of the lower die block; the left walls of the upper die cavity and the lower die cavity of the upper die block and the lower die block extend to the left end to form the left walls of the upper die and the lower die, and the left wall of the lower die is provided with a U-shaped positioning groove of which the lower end is completely matched with the blade positioning pin.
When the blade body is manufactured, the blade positioning sleeve with the positioning pin is installed on the blade handle, then the blade body is manufactured by placing the blade positioning sleeve and the blade handle together in the lower die cavity, and finally the upper die is subjected to die assembly and then hot pressing molding. Due to the positioning effect of the positioning pin, a machining structure for positioning the blade during mold forming is cancelled, the positioning pin is directly used for positioning, the twisting angle of the blade body can be accurately grasped, the accuracy of the mounting positions of the blade body and the positioning pin and the consistency of the deflection angle are ensured, the balance and the safety of the high-speed rotating blade are ensured, and the blade quality is improved.

FIG. 2 is a perspective view of a lower mold of the unitary mold with the blade mounted therein;
fig. 3 is a right side view of fig. 2.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
As shown in fig. 1, 2 and 3, the present embodiment includes an upper die 1 and a lower die. The lower die consists of a lower die block 2 and a cutting block 3 which is detachably fixed on the upper end surface of the lower die block 2. The left walls of the upper mold cavity and the lower mold cavity of the upper mold 1 and the lower mold block 2 and the left wall 9 of the lower mold cavity extend towards the left end to form the left wall of the upper mold and the left wall 8 of the lower mold, and the lower mold left wall 8 is provided with a U-shaped positioning groove 6 of which the lower end is completely matched with the blade positioning pin 5. When the blade body 7 is manufactured, the blade positioning sleeve 4 with the positioning pin 5 is firstly installed on the blade handle 10, then the blade body 7 is manufactured by placing the blade positioning sleeve and the blade handle together in a lower die cavity, and finally the upper die 1 is subjected to die assembly and hot pressing forming.
There are, of course, many other embodiments of the invention and modifications and variations of this invention that will be obvious to those skilled in the art may be made without departing from the spirit and scope of the invention, but it is intended to cover all such modifications and variations as fall within the true spirit and scope of the invention.
