The work of cylinder must be stablized, otherwise easily the stable of suspender carried in influence, as shakes, and suspender just may directly be pressed on the workpiece, and workpiece is damaged by pressure.The fixing device of suspender, needs to change and will slice off whole device with gas cutting in case damage owing to adopt the mode of welding to fix, and just can change, and changes very difficulty, wastes time and energy also out of reach requirement of precision when welding.
Summary of the invention
The utility model provide a kind of simple in structure, with low cost, commonality is good, the fixing device of the suspender of good stability, has solved cylinder leakage tester or fixing device job insecurity when dying, after the long-term use, wearing parts is changed the problem that wastes time and energy.
A kind of fixing device of suspender, comprise seat board, be fixed on the seat board cylinder and with the piston rod pivotally attached catch gear of cylinder, described catch gear can be with work-holding by cooperating with chuck on the seat board, described catch gear comprises pivotally attached adapter plate successively, the 3rd attaching parts, second attaching parts and clamp arm, adapter plate is fixed on the seat board, be fixed with on the clamp arm and seat board pivotally attached first attaching parts, the 3rd attaching parts middle part is hinged with the piston rod of cylinder, during clamping work pieces, the 3rd attaching parts by the piston rod pushing tow to second attaching parts on same vertical straight line, and stop clamp arm to rotate against the seat board sidewall.
Cylinder can be selected double-acting cylinder, can move reciprocatingly by the control cylinder piston rod.
The 3rd attaching parts is the T type, and an end and piston rod are hinged, and the other end and adapter plate are hinged, and the bottom and second attaching parts are hinged.The 3rd attaching parts can be selected T type connecting panel.During clamping, the plate body and the seat board plate body of T type connecting panel offset, and play position-limiting action, prevent that piston rod from continuing to move downward.
The 3rd attaching parts is hinged with H type connecting panel, can better captive joint with cylinder piston rod.During the chuck clamping work pieces of clamp arm,, form equilibrium of forces by first attaching parts, second attaching parts, T type connecting panel, adapter plate, stop clamp arm to rotate, even cylinder is died, the chuck of clamp arm also can firmly clamp with the locating piece chuck, and workpiece is dropped.
Chuck is provided with locating piece, and locating piece is fixed on the seat board, and convenient chuck to damage is changed.Captive joint can be selected welding, also can select bolt.
Seat board is provided with the pilot bar that an end and clamp arm vertically intersect, and it is excessive to prevent that workpiece from rocking, and workpiece is caused damage.
Hinged can the selection is connected with the pin of pin-and-hole coupling, be provided with wear proof copper sheathing in the pin-and-hole, pin-and-hole is same standard, can change easily when parts wear, even pin is used with also and can not brought influence to assembly precision during dismounting, reduced waste of time.
The pin two ends are provided with flat gasket, spring cotter, and flat gasket is set on the pin, and spring cotter passes the pin two ends, prevent that flat gasket from dropping.During replace worn part, only need change, and not need whole device is changed the single-piece worn parts.
The utility model is by being provided with a catch gear, make suspender clamp dying or leak gas and not having influence on the work of fixing device of exhaust hood, guaranteed the safety of workpiece, adopt articulated manner simultaneously, alleviated the weight of whole device, processing is simple, standardized production in batches, and locking property is better, and change simple, only need change just passable, improved maintenance of equipment efficient to a great extent, saved cost wear-out part.
