Detailed description of the invention
The enlarging locking fixture of self-locking thread insert 16 as shown in fig. 3 to 7, the power set comprising flare type joint 9 that axis extends in left-right direction, enlarging blind rivet 6 and drive enlarging blind rivet 6 to move left and right, the present embodiment medium power device is pneumatic riveting gun, the enlarging blind rivet sleeve pipe 8 that pneumatic riveting gun comprises riveting gun body 5 and is arranged on riveting gun body 5, enlarging blind rivet about 6 guiding movement is threaded onto in enlarging blind rivet sleeve pipe 8.The end 7 of enlarging blind rivet 6 is the pyramidal structure reduced gradually from left to right, flare type joint 9 comprise its right-hand member for pushing up the flared end 10 of press-fit and the link 11 for being threaded with enlarging blind rivet sleeve pipe 8 in use with the enlarging endoporus 2 of self-locking thread insert 16, flare type joint 9 is provided with for the screwed hole 15 of enlarging blind rivet sleeve pipe 8 plug-in mounting and the plug-in opening 14 for enlarging blind rivet 6 plug-in mounting, flare type joint 9 is installed on enlarging blind rivet sleeve pipe 8 by helicitic texture, flared end 10 comprise along its circumference spaced 6 for stretch to enlarging endoporus 2 in use and there is the expansion lobe 13 of dilatating and deformable in radial directions, the inwall of expansion lobe 13 is provided with the forced section for being made expansion lobe 13 radial expanding deformation oil by enlarging blind rivet 6 pushing tow when enlarging blind rivet 6 moves from left to right, in the present embodiment, forced section is the closing-in structure for enlarging blind rivet 6 pushing tow that the diameter from left to right surrounded by expansion lobe 13 diminishes gradually.In enlarging blind rivet 6 when moving from left to right, enlarging blind rivet 6 pushing tow expansion lobe 13, make expansion lobe 13 dilatating and deformable in radial directions, expansion lobe 13 holds out against and the enlarging endoporus 2 extruding self-locking thread insert 16 makes it expand, being expanded in the outer knurled portion 1 of self-locking thread insert 16 embeds among engine crankcase matrix 17, realize the self-locking fixation of this self-locking thread insert, use this automation, the enlarging locking fixture of mechanization solves in prior art to be undertaken locking by the instrument manually locking or use other not match and cause installing in batches and the low problem of operating efficiency.
The worked of enlarging locking fixture of this self-locking thread insert is called: be installed on engine crankcase matrix 17 with die nut by self-locking thread insert 16, flare type joint 9 is threadedly connected on enlarging blind rivet sleeve pipe 8, flared end 10 is inserted in the enlarging endoporus 2 of self-locking thread insert 16, pneumatic riveting gun 5 drives enlarging blind rivet 6 to stretch, the end 7 of enlarging blind rivet 6 drives expansion lobe 13 radial expanding deformation oil, thus carries out enlarging locking to the enlarging position of this self-locking thread insert 16.In use, the size adjusting enlarging amount can be carried out according to product practical set situation, external screw thread on the internal thread of the link 11 of flare type joint 9 and enlarging blind rivet sleeve pipe 8 matches, it is more that internal thread screws in the external screw thread position that matches, when carrying out enlarging, enlarging blind rivet 6 just has more long portion position and stretches out flare type joint 9, thus increase enlarging amount, otherwise, it is more that internal thread screws out the external screw thread position that matches, enlarging blind rivet 6 stretches out flare type joint 9 position will be relatively short, thus reduce enlarging amount, simultaneously, be equipped with special air pressure valve, the enlarging speed starting riveting gun is regulated by adjustable pressure size.
In other embodiments of the present utility model, power set also can adopt hydraulic gun; Can also be manually use hammer to replace pneumatic riveting gun; Pneumatic riveting gun also can not comprise enlarging blind rivet sleeve pipe, and now the link of flare type joint is provided with external screw thread and is directly connected with pneumatic riveting gun body; Also can offer pin-and-hole on enlarging blind rivet sleeve pipe, flare type joint adopts axle and pin-and-hole cooperation to be fixed on enlarging blind rivet sleeve pipe; Forced section may not be closing-in structure, can be to be arranged at the bulge-structure on expansion lobe inwall; The end of enlarging blind rivet may not be pyramidal structure, can be chondritic.
The embodiment of flare type joint is identical with the embodiment of the flare type joint in each embodiment of the enlarging locking fixture of above-mentioned self-locking thread insert, repeats no more herein.
