Top, even if connecting plate 6 is clamped with the second bindiny mechanism 3, even if also the first bindiny mechanism 2 and the second bindiny mechanism 3 carry out
Clamping.Pressed gas is passed through into the first stomata 8, the upper surface stress of piston 1 is moved down along its axis direction, 1 band of piston
Dynamic 14 synchronizing moving of limited block keeps limited block 14 mobile toward the direction of close movable block 12, so that limited block 14 drops to three
Between movable block 12, and then support limited block 14 mutually with three movable blocks 12, i.e. the one of the limit conical surface 15 and movable block 12
End is mutually supported, and 12 stress of movable block is made, and elastic deformation occurs for elastic component 13, and elastic component 13 compresses, and makes movable block 12 toward activity
The outside of through-hole 25 is mobile, so that the other end of movable block 12 passes through movable through-hole 25 and is moved to the outside of movable through-hole 25,
Loose axoide 16 is mutually supported with inclined-plane 17 is connect, i.e. three movable blocks 12 are abutted with the realization of the second link block, loose axoide 16
One upward thrust is generated to connection inclined-plane 17, the second bindiny mechanism 3 is made integrally to generate a upward active force, so that
Orientational cone-shaped surface 22 is close to positioning inclined-plane 23 can so as to realize the connection of the first bindiny mechanism 2 and the second bindiny mechanism 3
The connection for enough realizing crawl section, realizes the replacement of different crawl sections, and connection structure is more reliable, helps that manipulator is enable to have
Effect crawl object.
In addition, being passed through pressed gas into the second stomata 9, the lower surface stress of piston 1 is moved up along its axis direction,
Piston 1 drives 14 synchronizing moving of limited block, keeps the past direction far from movable block 12 of limited block 14 mobile, that is, limits the conical surface 15 and live
One end of motion block 12 separates, so that limited block 14 rises to the top of three movable blocks 12, elastic component 13 resets, and makes movable block 12
The medial movement of the past movable through-hole 25 of stress, so that the other end of movable block 12 passes through movable through-hole 25 and is moved to movable through-hole
25 inside, loose axoide 16 with connection inclined-plane 17 separate, and then orientational cone-shaped surface 22 with positioning inclined-plane 23 separate, make hinder stick 18 and
It connects through-hole and realizes separation, separated even if connecting plate 6 is realized with the second bindiny mechanism 3, even if also the first bindiny mechanism 2 and second
Bindiny mechanism 3 realizes separation, so as to realize the separation of crawl section, to replace different crawl sections.
Instantly when body of calming the anger suddenly disappears, piston 1 can generate the trend for moving up reset, but due to protection department 26 and prevent
Shield notch 27 matches, and supports protection department 26 and the outer wall of movable block 12 mutually, and protection department 26 can prevent movable block 12 from recycling
It resets, that is, movable block 12 is prevented to be advantageously implemented the automatically lock of retaining mechanism toward the medial movement of movable through-hole 25, prevent the
One bindiny mechanism 2 and the separation suddenly of the second bindiny mechanism 3, can effectively protect device and the safety of personnel.
To sum up, three 12 horizontal movements of movable block are driven by the axial movement of a limited block 14, realizes at 3 points and determines
The function of the heart, and limit the conical surface 15 and one end of movable block 12, loose axoide 16 and connect inclined-plane 17, orientational cone-shaped surface 22 and fixed
Position inclined-plane 23 is bonded in high precision can achieve the purpose that resetting, realize connection or separation using the elastic force of elastic component 13.
When piston 1 is moved down along its axis direction, make three movable blocks 12 simultaneously to activity by limiting the conical surface 15
The outside of through-hole 25 moves horizontally, and is all consistent by three 12 sizes of movable block in this present embodiment, so when three activities
When block 12 is displaced outwardly simultaneously, each loose axoide 16 can be contacted with connection inclined-plane 17 simultaneously, when loose axoide 16 makes the second company
Being supported when 3 entirety of connection mechanism moves up by orientational cone-shaped surface 22 and positioning inclined-plane 23 can make in the second bindiny mechanism 3
The heart keeps resetting, improves the accuracy of replacement.
In order to adapt to the different crawl section of quick-replaceable, crawl section is connected by tooling hole 21 with the second bindiny mechanism 3
It connects.By being passed through pressed gas into the second stomata 9, so that piston 1 is moved up along its axis direction, make limited block 14 toward far
Direction from movable block 12 is mobile, and elastic component 13 resets, so that movable block 12 resets, so that the first bindiny mechanism 2 and the
Two bindiny mechanisms 3 realize separation, i.e. the second bindiny mechanism 3 can unload from the first bindiny mechanism 2, connect crawl section with first
Connection mechanism 2 realizes separation, by the program of driving portion goes that corresponding second bindiny mechanism 3 is combined to can reach quick-replaceable institute again
Need the purpose of crawl section.
In order to realize the accurate control in automation engineering, it is equipped with magnetic induction mounting hole on mounting plate 5, pacifies in magnetic induction
Dress is equipped with inductor 20 in hole, by magnetic connection between inductor 20 and inductive rod 19, since inductive rod 19 can be with piston 1
Synchronizing moving, therefore the movement of piston 1 can be monitored by inductor 20, be conducive to improve automation control performance in this way, be conducive to
Improve the accuracy of replacement.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
