Abstract
The utility model relates to a tool for realizing the mechanical connection of a ring groove rivet, mainly comprising a cylinder body, a plunger, a clamping body, a push bar, a gripping jaw, a block sleeve and a die sleeve. The plunger and the clamping body are connected by a screw, and the inside of the clamping body is provided with an inner cone surface that is matched with the outer cone surface of the gripping jaw; the gripping jaw is split into three valves, and the top and bottom of the block sleeve are respectively provided with a boss. The ring groove rivet connection realized by the utility model can replace the screw connection or riveting, and cold riveting can be realized. The utility model has the advantages of big load, reliable pretightening force, fastened connection and convenient operation.
Description
The utility model is a kind of instrument of realizing the ring-grooved rivet mechanical connection.
At present mechanical connection extensively adopts and is threaded and common riveted joint, and it is low that these connect bearing capacitys, and it is unreliable to give tight power, and easily loosening, contradiction is more outstanding when bearing greater impact load.
The utility model purpose is to realize that with a kind of new tool the ring-grooved rivet cold riveting connects, and replaces being threaded and common riveted joint.
The utility model structure mainly contains the high pressure liquid cylinder pressure part of forming with cylinder body 1 and piston 2 as shown in Figure 1, and the switch 8 that clamp 3, push rod 4, jaw 5, shelves cover 6, die sleeve 7 are formed on operation mechanism's part and handgrip 15 and the handgrip is formed.
High-pressure cylinder is a double-action oil hydraulic cylinder, one end bar portion of piston 2 is threaded with clamp 3 usefulness of operation mechanism's part, and clamp 3 has inner conical surface 12, and matches with the male cone (strobilus masculinus) 16 of jaw 5, jaw 5 is divided into three lobes can radially be decontroled or tighten up, and shelves cover 6 all has boss 13,14 up and down.
Switch 8 no specific function and structures are the same with regular tap.
Working principle;
Can hold handgrip 15 control switchs 8 during work.
Cylinder body 1 and piston 2 provide pulling force and thrust, when piston 2 moves up, the tension section 11 of the jaw 5 clamping ring-grooved rivets in the clamp 3 is upwards strained (see figure 2), meanwhile die sleeve 7 downward cold-extrudeds press and overlap 10, make its radial contraction and compress fastener, tension loads and is broken up to ring-grooved rivet throat, and ring-grooved rivet 9 separates with tension section 11, promptly meet the requirements of and give tight power, finish being fastenedly connected.Jaw 5 initial gathering clamping tension sections 11 are to utilize push rod 4 jaw 5 to be pushed to the taper hole small end of clamp 3 under the effect of hydraulic pressure.When piston 2 moved down, shelves cover 6 utilized boss 13 to unclamp jaw 5 and utilizes boss 14 to release auxiliary connection again, finish the cold riveting work cycle like this one time.
The secondary (see figure 2) of ring-grooved rivet of the present utility model comprises the ring-grooved rivet 9 with the fastening part of triangle annular groove, and riveting cover 10, ring-grooved rivet have one section tension section 11 that trapezoidal annular groove is arranged of using when fastening.Tension section 11 promptly separates from rivet after being fastenedly connected finishing.
The utility model uses high-pressure liquid, the ring-grooved rivet gunman on switch 8 is housed, once press control mobile hydraulic station and finish starting continuously, clamp the tension section, loading is broken, and drill drift, unclamps tension section and six actions such as stops, and promptly finishes a circulation.
Effect:
1, can realize that high performance ring-grooved rivet connects, its bearing capacity gives tight power etc. and all is better than being threaded and common riveted joint.
2, ring-grooved rivet connection reliability height.
3, easy and simple to handle, quick, the work noiseless of hydraulic pressure groove riveting gun.
