314 are moved to suitable position to warehouse compartment C, then demand frock clamp and the connection of the second traction mechanism 314；Second traction mechanism
314 drive demand frock clamps are moved on pallet 51；First driving mechanism drives pallet 51 and demand frock clamp, is down to vertical
The first layer of body fixture repository；Second traction mechanism 314 drives demand frock clamp to be moved to idle warehouse compartment B, and divides therewith
From demand fixture is moved to warehouse compartment B.Second traction mechanism 314 is moved to suitable position toward warehouse compartment A, then the tooling of warehouse compartment A
Fixture is connected with traction mechanism；Second traction mechanism 314 drives the frock clamp of warehouse compartment A to be moved on pallet 51；First driving
Mechanism drive pallet 51 rises to the second layer of three-dimensional fixture repository；Second traction mechanism 314 drives the frock clamp of warehouse compartment A to move
It moves to warehouse compartment C and disconnected；Then the second traction mechanism 314 resets, and the movement of falling library is completed.
It when carrying out fixture switching action, need to temporarily stop production, the first moving component 11 drives the frock clamp on former station
The centre of frame is moved to along guide rail；The first traction mechanism 36 on first moving component 11 is moved to warehouse compartment B；Then former work
The demand frock clamp of clamps and warehouse compartment B are connect with the first traction mechanism 36 simultaneously；First traction mechanism 36 drives former tooling
The demand frock clamp of fixture and warehouse compartment B are moved to warehouse compartment A, and then three separates, and former frock clamp is made to be moved to warehouse compartment A, and
The demand frock clamp of warehouse compartment B is then moved on the first moving component 11；First traction mechanism 36 resets；First moving component 11
Drive demand frock clamp is moved on station along guide rail, and fixture switching action is completed.
Certainly, the invention is not limited to above embodiment, and those skilled in the art are without prejudice to originally
Equivalent deformation or replacement can be also made under the premise of spirit, these equivalent variation or replacement are all contained in the application right
It is required that in limited range.
