Abstract
The invention discloses a kind of bearing-free composite material blade molds, including lower die and upper mold, it is provided with die cavity in the lower die, the shape of the die cavity and the shape of bearing-free composite material blade match, one end in the die cavity is provided with guide pin, the guide pin activity is inserted into upper mold, and one end in the die cavity close to guide pin is provided with limiting plate, is matched close to the shape of one end of guide pin and the covering blade root of blade in the die cavity.The present invention has many advantages, such as that processing effect is good, high precision machining.
Description
Technical field
The present invention relates to rotor field of measuring technique, a kind of specifically bearing-free composite material blade mold.
Background technology
Helicopter Main will be set by body and lift (containing rotor and tail-rotor), power, transmission three digest journals and onboard flight
It is standby to wait composition.Rotor generally passes through the machinery that is made of transmission shaft and retarder etc. by turboaxle motor or piston-mode motor
Transmission system drives, and can also be driven by reaction force that blade tip jet generates.
Bearing-free composite material blade is the important component of helicopter, is the song of complexity at the covering blade root of blade
Face is added currently, the method mainly used is covering to be done at the time of molding longer with five shaft mechanicals in the overshoot of blade processing
Construction equipment cooperation fixing tool is cut, and design requirement is reached, but difficulty of processing in this way is larger, and processing effect compares
Difference needs effectively to be improved.
Invention content
The defect that the purpose of the present invention is to solve difficulty of processing in the prior art is larger, processing effect is poor, carries
It solves the above problems for a kind of bearing-free composite material blade mold.
To achieve the goals above, technical scheme is as follows：The invention discloses a kind of bearing-free composite materials
Blade mold, including lower die and upper mold are provided with die cavity, shape and the bearing-free composite material of the die cavity in the lower die
The shape of blade matches, and one end in the die cavity is provided with guide pin, and the guide pin activity is inserted into upper mold,
One end in the die cavity close to guide pin is provided with limiting plate, in the die cavity close to the shape of one end of guide pin with
The covering blade root of blade matches.
Preferably, one end far from guide pin is provided with counterweight in the die cavity.
Preferably, being provided with locating piece in the lower die, the mode being connected through a screw thread on the locating piece is pacified
Equipped with positioning bolt, the mode that the screw rod of the positioning bolt is connected through a screw thread is installed into upper mold.
The present invention has the following advantages compared with prior art：
1, difficulty of processing is larger；
2, machining accuracy is higher.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of bearing-free composite material blade mold of the present invention；
Fig. 2 is a kind of dimensional structure diagram of bearing-free composite material blade mold of the present invention；
Fig. 3 is the detail view of structure A；
Fig. 4 is the detail view of structure B.
Reference numeral is：Lower die 1, upper mold 2, die cavity 3, guide pin 4, limiting plate 5, counterweight 6, locating piece 7, positioning bolt
8。
Specific implementation mode
The effect of to make to structure feature of the invention and being reached, has a better understanding and awareness, to preferable
Embodiment and attached drawing cooperation detailed description, are described as follows：
As shown in Figure 1, the invention discloses a kind of bearing-free composite material blade mold, including lower die 1 and upper mold 2,
It is characterized in that：Die cavity 3, the shape of the die cavity 3 and the shape phase of bearing-free composite material blade are provided in the lower die 1
It matches, one end in the die cavity 3 is provided with guide pin 4, and 4 activity of guide pin is inserted into upper mold 1, the mould
One end of guide pin 4 is provided with limiting plate 5 in slot 3, close to the shape and paddle of one end of guide pin 4 in the die cavity 3
The covering blade root of leaf matches.
The composite material for being used to prepare blade is put into die cavity 3, and upper mold 2 is then covered, and guide pin 4 is played to upper mold
The purpose of 2 progress positioning and guidings is leaned on since the shape and the shape of bearing-free composite material blade of die cavity 3 match in die cavity 3
The shape of one end and the covering blade root of blade of nearly guide pin 4 match, and after material setting to be composite, that is, bearing-free are prepared
Composite material blade, whole process operation are more convenient.
Preferably, one end far from guide pin 4 in the die cavity 3 is provided with counterweight 6, by the way that counterweight 6 is arranged,
The purpose of counterweight is played, such stability is preferable, the processing efficiency higher of blade, and processing effect is more preferable.
Preferably, locating piece 7 is provided in the lower die 1, the mode being connected through a screw thread on the locating piece 7
Positioning bolt 8 is installed, the mode that the screw rod of the positioning bolt 8 is connected through a screw thread is installed into upper mold 2, passes through setting
Upper mold 2 and lower die 1 can preferably be positioned together, further improve blade by locating piece 7 and positioning bolt 8 in this way
Processing effect.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
Improvement is both fallen in the range of claimed invention.The present invention claims protection domain by appended claims and its
Equivalent defines.
