Technical field
The utility model relates to a kind of Novel hand-held pincers that press, for aviation, automobile and other industries high strength sheet metal component riveted joint assembling.
Background technology
At present, when the process and assemble such as aircraft, automobile, for improving reliability and the production efficiency of assembling, often adopt diameter aluminum rivet and steel rivet to rivet assembling, owing to being subject to product structure size restrictions, working site cannot be riveted by application machine equipment, needs a kind of portable high-power pincers that press, the portable pincers that press in the past, appearance and size is large, inconvenient operation, labour intensity is high, affects operating efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Novel hand-held pincers that press, and this Novel hand-held presses pincers for the riveted joint assembling of high strength rivet, alleviates operator's labour intensity, enhances productivity.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of Novel hand-held pincers that press, pivoted arm is flexibly connected by bearing pin I with fixed arm, the end of fixed arm is connected with protecgulum, in protecgulum, be provided with two rotating directive wheels, above two directive wheels, common and pivoted arm are taken turns tangently, and pivoted arm Lun center is flexibly connected with the end of pivoted arm; Middle part at pivoted arm is provided with extension spring, and the other end of extension spring is connected with the end face of protecgulum; Rear end face at protecgulum is provided with cylinder body, is provided with air operated reversing valve in cylinder body, the end connecting wedge of the piston rod of air operated reversing valve, and the front end tip of voussoir is corresponding with the tangent plane position of directive wheel and pivoted arm wheel.
The structure of described air operated reversing valve is, is provided with large piston in cylinder body, is provided with the bonnet of valve piston housing structure in the end of cylinder body, is provided with valve piston in bonnet, between large piston and valve piston, connects by piston rod; Outside at bonnet is provided with changement, and structure for to be provided with valve body in valve seat, and reversing bar is by being slidably connected in sealed at both ends circle and valve body, and one end of reversing bar is stretched out valve seat and is connected with trigger, and the other end of reversing bar is landed in valve seat by spring.
The outside of described extension spring fastens protective cover; On trigger, be provided with handle.
This Novel hand-held presses and clamps the piston rod connecting wedge that adopts air operated reversing valve, drives pivoted arm wheel to roll on voussoir by the motion of voussoir, rotates centered by bearing pin I thereby realize pivoted arm, realizes the work of the rivet that presses.
The application adopts duplex cylinder structure, has increased motive force, adopts voussoir force-increasing mechanism, and voussoir is designed to two kinds of curved-surface structures, and reliable operation, pressure are large, and idle stroke fast moving, saves time, and while pressing work, thrust is amplified at double.The application's the Novel hand-held wrench structure size that presses is little, lightweight, can reduce labor intensity, and enhances productivity.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of Novel hand-held pincers that press, pivoted arm 1 is flexibly connected by bearing pin I 15 with fixed arm 2, the end of fixed arm is connected with protecgulum 4, in protecgulum, be provided with two rotating directive wheels 28, above two directive wheels 28, common and pivoted arm is taken turns 17 tangently, and pivoted arm Lun17 center is flexibly connected with the end of pivoted arm 1; Be provided with extension spring 16 at the middle part of pivoted arm 1, the other end of extension spring 16 is connected with the end face of protecgulum 4; Be provided with cylinder body 20 at the rear end face of protecgulum 4, in cylinder body 20, be provided with air operated reversing valve 10, the end connecting wedge 21 of the piston rod 26 of air operated reversing valve 10, the front end tip of voussoir 21 is corresponding with the tangent plane position of directive wheel 28 and pivoted arm wheel 17.
As shown in Figure 3, the structure of described air operated reversing valve 10 is, is provided with large piston 23 in cylinder body 20, is provided with the bonnet 27 of valve piston housing structure in the end of cylinder body 20, in bonnet 27, be provided with valve piston 25, between large piston 23 and valve piston 25, connect by piston rod 26; Outside at bonnet 27 is provided with changement, structure for being provided with valve body 11 in valve seat 19, reversing bar 9 is by being slidably connected in sealed at both ends circle 12 and valve body 11, and one end of reversing bar 9 is stretched out valve seat 19 and is connected with trigger 7, and the other end of reversing bar 9 is landed in valve seat 19 by spring 13.
The outside of described extension spring 16 fastens protective cover 3; On trigger 7, be provided with handle 24.
Its course of work is: original state is that extension spring 16 pulls between pivoted arm 1 and fixed arm 2 as released state; When after the tail end ventilation in bonnet 27, promote piston rod 26 and advance, valve piston 25 drives large piston 23, and voussoir 21 is inserted into pivoted arm takes turns 17 belows, and pivoted arm 1 take turns 17 movement by pivoted arm, pivoted arm 1 and fixed arm 2 are fastened, and completes the work of pressing.After finishing when pressing, press trigger 7, drive reversing bar 9 to move by push rod 8, gas circuit is transferred to large piston 23 ends, because the lifting surface area of large piston 23 is large, therefore opening speed is fast, voussoir 21 is back to original position, and pivoted arm 1 exists in the drive of extension spring 16, again opens.
