Detailed description of the invention
It can be seen that a kind of width expansion mechanism from Fig. 1, Fig. 2, Fig. 3, Fig. 4, it includes cylinder 1, connector 2, connects
Screw rod 4, trapezoidal slide block 5, support seat 6, drive link 7, first are expanded block 8, second and are expanded block 9, expansion pedestal 11 etc..Described cylinder
1 is installed on below support seat 6, and drive link 7 is arranged on support seat 6 top, and cylinder 1 is connected with drive link 7 by connector 2, band
Dynamic drive link 7 displacement.The fixed installation of described expansion pedestal 11 is to support on seat 6, and its bottom surface is installed a feather key 12,
Forward vertical installs a guide finger 10；Described first expansion block 8 and the second expansion block 9 are arranged on expansion pedestal 11, and first expands
Open block 8 bottom surface be provided with and expand the chute that on pedestal 11, feather key 12 is corresponding, the second expansion block 9 is vertically provided with and expands
The inclined-plane that longitudinal chute that on pedestal, guide finger 10 matches, the first expansion block and the second expansion block contact is provided with and matches
T-shaped key and T-shaped groove, first expansion block rear portion be additionally provided with T-slot.Described connection screw rod 4 one end connects drive link 7, separately
One end connects trapezoidal cunning 5 pieces, and the T-slot that trapezoidal slide block 5 is provided with the first expansion block 8 rear portion coordinates, and trapezoidal slide block 5 can be first
The T-slot of expansion block 8 rear end slides laterally.When cylinder 1 protracts or shrinks, drive trapezoidal slide block 5 to seesaw, and then promote the
The one expansion block 8 feather key 12 along expansion pedestal 11 moves, and the second expansion block 9 is under the effect of the first expansion block 8, along guiding
Pin 10 inside and outside moves, it is achieved width expansion or contractive action.
Further, described support seat 6 is provided with gathering sill, and drive link 7 is arranged in gathering sill, it is simple to drive link orientation is moved
Dynamic.
Further, one end that described connection screw rod 4 is connected with drive link 7 is additionally provided with a locking nut 3, passes through locking screw
Female 3 adjust the connecting length connecting screw rod with drive link.
Further, described feather key 12 is angularly disposed before and after expanding on pedestal, the most described first expansion block 8 end
The chute that face is provided with is the most angularly disposed.First expansion block moves along the most angularly disposed feather key.That is feather key
With chute the movable centrage of deviation is set, it is ensured that can expand outwardly while the first expansion block is movable or inwards
Shrink.
Further, described first expansion block 8 and the second expansion block 9 fit in rectangle and are arranged on expansion pedestal 11, and first
The inclined-plane of expansion block 8 is provided with T-shaped key, and the inclined-plane of the second expansion block 9 is provided with T-shaped groove accordingly.
When this utility model cylinder extension or contraction, drive trapezoidal slide block to seesaw, and then promote the first expansion block edge
Feather key on expansion pedestal moves, and the second expansion block, under the effect of the first expansion block, inside and outside moves along guide finger, it is achieved wide
Degree expansion or contractive action.Specifically: during cylinder extension, promoting drive link to travel forward by connector, drive link is by even
Connecing screw rod promotes trapezoidal slide block to travel forward, and trapezoidal slide block expands block along first while driving the first expansion block movable
The T-slot at rear portion slides laterally；Thus promote first expansion block feather key along expansion pedestal to be displaced outwardly forward；Same with this
Time, under the mating reaction by the T-shaped key in inclined-plane contacted with the first expansion block and T-shaped groove of the second expansion block, the second expansion
Longitudinal chute on block moves along guide finger, expands outwardly, it is achieved width expansion action.When cylinder shrinks, received by connector
Contracting drive link rearward movement, drive link pulls trapezoidal slide block rearward movement by connecting screw rod, makes trapezoidal slide block expand relative to first
Open block, along expanding the pedestal feather key with angle of inclination, relatively transverse slip occurs, thus promote the first expansion block the most inside
Mobile.Moving inward backward of first expansion block, by the T-shaped key of inclination under the effect of guide finger, pulls the second expansion block edge
The gathering sill longitudinal chute on contract, the second expansion block moves along guide finger, realizes shrinkage in width action to contract.
Rationally, assembling is simple, easy for operation for this utility model composition, is a kind of preferably width expansion mechanism.Special
When not being suitable to crankshaft thrust mirror polish, the tensioner expansion of polishing abrasive belt uses.
