A threaded pin limiting hole can be formed in a certain position on the back of the folding wing mounting seat 1, and a flat-end fastening threaded pin is inserted into the threaded pin limiting hole to limit the connecting rod component.
The assembling process of the inserted-rod type locking device for unfolding the folding wings of the micro steering engine is specifically described below.
The folding wing 2 is vertically placed in the through groove of the folding wing mounting seat 1, the end part of the folding wing 2 used for connecting the folding wing mounting seat 1 is inserted between the two limiting pieces, and the through holes of the two limiting pieces are opposite to the connecting holes of the folding wing 2.
The U-shaped connecting rod of the torsion spring 4 is clamped at the root of the folding wing 2, and the two torsion springs of the torsion spring 4 are aligned to the through holes of the two limiting pieces.
The folding wing shaft 3 penetrates into the through holes of the two torsion springs, the two limiting pieces and the connecting hole of the folding wing mounting seat 1 from one end provided with the pin hole, and then the torsion spring stop pin 5 is inserted into the pin hole.
The thimble 6, the compression spring 7 and the connecting gland 8 are sequentially assembled to enable the spherical surface of the thimble 6 to be outward, a first arm connected with the gland 8 is connected with the connecting rod 9 through the first rotary joint, the connecting rod 9 is connected with the swing rod 10 through the third rotary joint, and the swing rod 10 is connected with the inserted link 11 through the fourth rotary joint, so that the connecting rod part, the thimble spring part and the inserted link 11 form a whole.
The insertion rod 11 is inserted through a fixing ring on the back surface of the folding wing mounting base 1, and the link 9 is fixed to the back surface of the folding wing mounting base 1 by a second rotary joint.
The working principle of the insertion rod type locking device for unfolding the folding wings of the micro steering engine is specifically described below.
When the folding wing 2 is folded, the bottom arc of the folding wing 2 is not contacted with the thimble 6, the bottom sheet-shaped check block of the folding wing 2 is abutted against the free end of the inserted link 11, and at the moment, the inserted link type locking device is in an original state.
After the folding wing 2 starts to be unfolded, the sheet-shaped stop block at the bottom of the folding wing 2 is far away from the free end of the insertion rod 11, and the circular arc at the bottom of the folding wing 2 presses the spherical surface of the thimble 6, so that the thimble 6 is forced to move under the driving of the circular arc at the bottom of the folding wing 2. The connecting rod 9 starts to rotate around the second rotary joint as an axis, so that the inserted rod 11 is driven to move along the axial direction of the inserted rod 11 under the restriction of the fixed ring through the swing rod 10.
After the folding wing 2 is unfolded in place, the side surface of the inserted link 11 is pressed against the bottom stop of the folding wing 2, so that the folding wing 2 is locked by the pressed thimble 6 and the pressed inserted link 11.
If the folding wing 2 is to be folded, the connecting rod 9 is manually rotated to make the inserting rod 11 move axially along the inserting rod 11 and far away from the bottom stop position of the folding wing 2, and at this time, the thimble 6 forces the folding wing 2 to be folded because the thimble 6 presses the bottom arc of the folding wing 2. The action of the manual rotation connecting rod 9 cannot be too large due to the blocking of the limiting pin 12, and the folding of the folding wings 2 is realized as long as the bottom sheet-shaped block of the folding wings 2 is collided with the free end of the inserting rod 11 again. The thimble 6 no longer contacts the bottom arc of the folding wing 2.
The inserted link type locking device for unfolding the folding wings of the miniature steering engine guarantees that the folding wings can be continuously unfolded in the missile flying process, and improves the stability of missile flying.
