Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
As shown in Figure 1, a kind of fixture of reinforcing bar cage seam welding, including main shaft 1, it is set on main shaft 1 and can be along 1 axis of main shaft
To the casing 2 of sliding, for the cylinder 3 of the sliding of drive sleeve 2.It is provided with external disk 11 on main shaft 1, inner disc is provided on casing 2
21, multiple flexible binding clasps 4 are provided between external disk 11 and inner disc 21.
It is fixed with mounting bracket 12 on main shaft 1, the position on main shaft 1 between mounting bracket 12 and casing 2 is hinged with main thick stick
Bar 13.Two intermediate bars that main lever 13 includes two main rod bodies 131 hinged with main shaft 1, connect two main rod bodies 131
132, wherein two main rod bodies 131 are mutually parallel, two intermediate bars 132 are mutually parallel.In two main rod bodies 131 and two centres
Bar 132 surrounds in the box formed and is additionally provided with force rod 133, and the both ends of force rod 133 are individually fixed in two intermediate bars 132
Middle part.Two main rod bodies 131 and the articulated position of main shaft 1 are located at the radially opposite sides of main shaft 1.
Cylinder 3 includes cylinder seat 31 and piston rod 32, and piston rod 32 can axially be moved according to the air pressure change in cylinder seat 31 along it
It is dynamic.Wherein cylinder seat 31 is articulated with mounting bracket 12, and the end of piston rod 32 is articulated with force rod 133.
Two auxiliary levers 22 are hinged on casing 2, the articulated position of two auxiliary levers 22 and casing 2 is located at casing 2
Radially opposite sides, and be in same plane with the articulated position of main rod body 131 and main shaft 1.The other end of two auxiliary levers 22 point
It is not articulated in two main rod bodies 131, the distance between hinge joint and main shaft 1 are less than the hinge joint and main shaft 1 of piston rod 32
Distance.When then piston rod 32 is extended relative to cylinder seat 31, piston rod 32 drives entire main lever 13 to occur by force rod 133
Rotation, main lever 13 drive auxiliary lever 22 to move, and auxiliary lever 22 further pushes casing 2 to be slided on main shaft 1.
As depicted in figs. 1 and 2, inner disc 21 is circular ring shape, and main shaft 1 is pierced by from the interior annular distance of inner disc 21.The end face of inner disc 21
On offer multiple regulating tanks 211 through inner disc 21, the quantity of regulating tank 211 is identical as the quantity of flexible binding clasp 4, adjust
Section slot 211 is the length direction of bar shaped and all regulating tanks 211 by the center of circle of external disk 11, and all regulating tanks 211 are opposite
It is centrosymmetric distribution in the axis of inner disc 21.
Flexible binding clasp 4 includes outer sleeve 41 and the inner sleeve 42 being slidably arranged in outer sleeve 41.It is leaned on outer sleeve 41
The end for being bordering on inner disc 21 offers threaded hole 411, and 411 internal thread of threaded hole is connected with adjusting bolt 412, adjusting bolt 412
Thread segment be located in regulating tank 211, it is outer and can not pass through regulating tank 211 that the stubborn head of adjusting bolt 412 is located at regulating tank 211.
Adjusting bolt 412 is then tightened in threaded hole 411, you can flexible binding clasp 4 is fixed on inner disc 21;Unclamp adjusting bolt
After 412, position of the flexible binding clasp 4 relative to regulating tank 211 can be adjusted, to process the steel bar framework of different-diameter,
Expand the use scope of this fixture.
Inner sleeve 42 is the tube-in-tube structure of cylinder, and the inner tube wall of inner sleeve 42 is the mounting hole 421 for penetrating reinforcing bar,
The oral area of mounting hole 421 offers chamfering 422, and when penetrating reinforcing bar, chamfering 422 can be that reinforcing bar plays guiding role, make reinforcing bar more
Easily it is inserted into mounting hole 421.Several ball 423 are offered on the side wall of inner sleeve 42, and steel is both provided in several ball 423
Ball 424, the diameter of ball 424 is more than the wall thickness of inner sleeve 42.
As shown in Figures 2 and 3, the inner wall of outer sleeve 41 is provided with the magnet layer 413 of tubular, and magnet layer 413 is towards inner sleeve
The cylindrical surface of 42 axis of cylinder is set as guide surface 414, and guide surface 414 is taper, and guide surface 414 is close to 421 oral area of mounting hole
Internal diameter is larger, and the internal diameter far from 421 oral area of mounting hole is smaller.When inner sleeve 42 to outer sleeve 41 close to when, guide surface 414 with rolling
Pearl 424 offsets, and ball 424 is driven to be moved to the axis direction of inner sleeve 42.In the course of work, magnet layer 413 can incite somebody to action always
The ball 424 of steel is sucked, and reduces the probability that ball 424 is detached with guide surface 414.
As shown in Fig. 2, spring 43 is provided between outer sleeve 41 and inner sleeve 42, one end and the inner sleeve 42 of spring 43
The other end of end abutment, spring 43 is abutted with outer sleeve 41, and spring 43 is used to drive inner sleeve 42 to far from outer sleeve 41
It moves in direction.
As depicted in figs. 1 and 2, external disk 11 is fixed on the end of main shaft 1 and parallel with inner disc 21, is corresponded in external disk 11
In flexible binding clasp 4 offer it is multiple penetrate hole 111, shape and the arrangement mode for penetrating hole 111 are identical as regulating tank 211.It is interior
Sleeve 42 is ladder-like close to the end set in hole 111 is penetrated, and the end of inner sleeve 42, which can enter, to be penetrated in hole 111, and interior
The relatively large ontology of 42 diameter of sleeve, which cannot be introduced into, penetrates hole 111.
It is inserted into corresponding mounting hole 421 in use, more reinforcing bars are each passed through to penetrate behind hole 111, then controls gas
Cylinder 3 extends, and cylinder 3 drives main lever 13 to be rotated around its hinged place, and drives auxiliary lever 22 that casing 2 is pushed to move, then external disk 11
The distance between inner disc 21 is gradually reduced, and external disk 11 offsets with inner sleeve 42, and overcomes the elastic force of spring 43 by inner sleeve 42
Push to inside outer sleeve 41.Several balls 424 move under the guiding role of guide surface 414 to the axis direction of inner sleeve 42,
And steel bar clamping is completed into clamping.
Since main lever 13 and auxiliary lever 22 form lever construction, so the thrust applied in cylinder 3 is certain feelings
Under condition, the thrust size of the movement of drive sleeve 2 is improved, to which reinforcing bar to be reliably clamped.The fixture of this reinforcing bar cage seam welding
Chucking power is improved under the premise of not improving driving force, therefore the course of work is more energy saving, and only need compressed air complete
It is more environmentally protective compared with hydraulic pressure at clamping.
When needing to unclamp this fixture, control cylinder 3 shortens, then 3 drive sleeve 2 of cylinder is moved toward away from the direction of external disk 11
Dynamic, external disk 11 and inner disc 21 are located remotely from each other, and inner sleeve 42 loses the pressing force from axial direction, then spring 43 drives inner sleeve 42
It is moved to the direction far from outer sleeve 41, ball 424 loses the pressure from guide surface 414, at this time can more easily
Reinforcing bar is taken out from this fixture, completes blanking.
The above is only the exemplary embodiment of the utility model, the protection model rather than limited the present invention
It encloses, the scope of protection of the utility model is determined by the attached claims.
