Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
As shown, quick overturning jacking mechanism in embodiment mainly by mounting base 1, axis pin 2, handle 3, turning frame 4,
Tighten handle 5, flipping block 6, lifting axe 7, small clevis pin with head 8, holding screw 9, steel ball 10, spring 11, bulb resilient clip 12 etc. zero
Part is constituted.
As shown in Fig. 1 ~ Fig. 3, the mounting base 1 is fixed on when installing application on fixture, and 1 top of mounting base is equipped with installation
Slot, the flipping block 6 are hinged on by small clevis pin with head 8 in mounting base 1, and the small clevis pin with head 8 is mounted on the both sides side plate of mounting groove,
Flipping block 6 can be rotated freely with small clevis pin with head 8 for center of rotation, and flipping block 6 is flipped up to when extreme position and mounting groove bottom
Portion leans；The flipping block 6 is equipped with pin hole, and the lifting axe 7 is assemblied in the pin hole and can be free to move axially,
The handle 5 of tightening is threaded in the screw thread of the pin hole left end, is tightened 5 right end of handle and is connect with the lifting axe 7, top
7 right end of mandrel is for top tight workpiece and positions；The turning frame 4 is hinged on by axis pin 2 in mounting base 1, and the axis pin 2 is installed
In mounting base 1, turning frame 4 can be rotated freely with axis pin 2 for center of rotation, when turning frame 4 is flipped up to extreme position
Virtual pressure is on flipping block 6.When 7 top tight workpiece of lifting axe, flipping block 6 is slightly reverse rotation and realizes interlocking with turning frame 4.
As shown in Fig. 1 ~ Fig. 3, in the present embodiment, the threaded connection of the handle 3 is fixed on turning frame 4, the effect of handle 3
It is that turning frame 4 is driven to be overturn clockwise or counterclockwise, is conveniently operated.
As shown in Fig. 1 ~ Fig. 3, in the present embodiment, spring 11 is set on the lifting axe 7, the spring 11 is with lifting axe
7 are installed along in the pin hole on flipping block 6, and 11 left end of spring is connect with lifting axe 7, and 11 right end of spring is connect with flipping block 6；
The right side for tightening handle 5 is equipped with groove, and the groove is embedded with steel ball 10, and 10 top pressure of the steel ball is in the lifting axe
On 7 inner face.By using such structure design, when tightening handle 5 and loosening, spring 11 can make lifting axe 7 automatic
It retracts.The point contact of steel ball 10 and lifting axe 7, the absorbable tangential force for tightening handle 5, makes lifting axe 7 be operated without revolution, only
It is axially moved, prevents the rotating belt because of lifting axe 7 from starting building part revolution, and influence being properly positioned for workpiece.
As shown in Figure 1, in the present embodiment, holding screw 9,9 inner end of holding screw top are installed on the flipping block 6
Tight small clevis pin with head 8, can prevent small clevis pin with head 8 from deviating from this way.
As shown in Figure 1 and Figure 2, in the present embodiment, bulb bullet is respectively equipped on the madial wall of the both sides side plate of the mounting groove
Property clamp 12, and the vertical range between both sides bulb resilient clip 12 be less than the flipping block 6 thickness.In this way, bulb
Resilient clip 12 is prevented from flipping block 6 and is overturn clockwise under outer force-disturbance into work pieces process region and cause to hit knife, i.e.,
Ensure to avoid the machining area of workpiece.
The operation principle and the course of work of the present invention enters as follows：
When workpiece needs positioning compression, by flipping block 6 clockwise overturn, flipping block 6 drive tighten handle 5, steel ball 10,
The parts such as spring 11 and lifting axe 7 are flipped up together to extreme position, and flipping block 6 leans with mounting base 1.Then handle is stirred
Hand 3, handle 3 drives turning frame 4, and overturning is to extreme position clockwise, and 4 virtual pressure of turning frame is on flipping block 6.Then rotation is tightened
Handle 5, makes to tighten handle 5 and moves right, and tightens handle 5 and pushes lifting axe 7 to compress spring 11 by steel ball 10, lifting axe 7
Move right simultaneously contact workpiece；The reaction force of workpiece by steel ball 10 and is tightened handle 5 and passes to flipping block 6 by lifting axe 7,
So that flipping block 6 turning anticlockwise and is contacted turning frame 4 to the left, active force is applied on turning frame 4, and the anti-work of turning frame 4
Firmly flipping block 6 is prevented to continue to rotate counterclockwise, no longer rotated to make lifting axe 7 be maintained at a certain position, continued rotation and twist
Tight handle 5, lifting axe 7 is with regard to top tight workpiece.
After the completion of workpiece positioning, handle 5 is tightened in reverse rotation, is made to tighten handle 5 and is moved to the left, and lifting axe 7 is in spring 11
Rebound effect under be moved to the left, withdraw workpiece.Flipping block 6 is allocated to extreme position clockwise again, is then stirred counterclockwise
Handle 3, handle 3 drive 4 turning anticlockwise of turning frame to lower limit position.It stirs flipping block 6 counterclockwise again and returns back to limit inferior
Position.Due to flipping block 6 and tighten the centers of gravity of the parts such as handle 5 in the left side of respective center of rotation, gravity away from effect
Under, it flipping block 6 and tightens handle 5 and can be maintained at lower limit position【Fig. 1 is turning frame 4, flipping block 6 and tightens handle 5 counterclockwise
Return back to the state of lower limit position】.
The present invention makes flipping block 6 by active force to the left by the relative position of reasonable arrangement axis pin 2 and small clevis pin with head 8
When, flipping block 6 prevents flipping block 6 from rotating counterclockwise to the active force of turning frame 4, reverse interlocking, to ensure to tighten handle 5
Power finally acts on workpiece in an axial direction, top tight workpiece.
