Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and example is served only for explaining invention, not
For limiting the scope of the invention.
A kind of blind riveting flexibility switching device, including metal stereotypes hoses 1, cable wire 2, adapter 1, windowing swivel nut 4,
Swivel nut 5, adjustable cap nut 6, adapter 27, pin 8, screw rod 9 and special type screw nut 10, cable wire 2 pass through metal stereotypes hoses
Inside 1, rear end is tied up on adapter 1 on the pin 8 that 2 front end of cable wire is fixed on adapter 27, setting in adapter 1
There is threaded hole and be mounted in the inside of windowing swivel nut 4, windowing swivel nut 4 is connected through a screw thread with metal stereotypes hoses 1, adapter 27
Inside swivel nut 5, swivel nut 5 is connected through a screw thread with metal stereotypes hoses 1, and adapter 27 and screw rod 9 pass through embedded company
It connects, adjustable cap nut 6 is connected through a screw thread with swivel nut 5, and adjustable 6 rear end of cap nut is equipped with special type screw nut 10.
The windowing swivel nut 4 of blind riveting flexibility switching device is using windowing form and indicates 0 groove, one 3 subscript of adapter
There is graduation mark and is located at the windowing windowing of swivel nut 4 position.6 external cylindrical surface of adjustable cap nut of blind riveting flexibility switching device
It is set as Hexagon hole for front in knurling, 9 rear end of screw rod is provided with hexagonal axis, can adjust the Hexagon hole of cap nut 6
It is cooperatively connected with the hexagonal shaft part of screw rod 9.5 front end of swivel nut of blind riveting flexibility switching device is provided with external screw thread and outer
Screw thread is higher than non-threaded section of outer rim, is provided with one section of cavity area and cavity area before adjustable 6 internal screw thread of cap nut
Greater than the external screw thread region on swivel nut 5.It is plane or preceding that the adjustable cap nut 6 of blind riveting flexibility switching device, which has front end,
The end band conical surface.
In riveting, thread hollow rivet 11 is screwed on screw rod 9, makes 11, thread hollow rivet and adjustable housing spiral shell
Female 6 front end abutments.By pumping nail rifle 14 or pumping nail pincers on screw rod be screwed in the threaded hole in adapter 1, make pumping nail rifle 14 or
Pumping nail clamps front end face and abuts with windowing 4 rear end face of swivel nut.
Metal stereotypes hoses 1, cable wire 2 are bent into certain shapes as needed, a people catches adjustable cap nut 6 will
In the rivet hole of the insertion riveting object of thread hollow rivet 11, firmly compressing adjustable cap nut 6 makes thread hollow rivet 11
Head is close to riveting object.Another people operates pumping nail rifle 14 or pumping nail pincers at convenient for construction, and pumping nail rifle 14 or pumping nail are clamped slightly
Force pre-tightens, the initial scale value of adapter 1 before observation riveting at windowing 4 windowing of swivel nut.Pumping nail rifle 14 or pumping nail are clamped
It slowly exerts a force, pulls screw rod 9 to move by adapter 1, cable wire 2, adapter 27, force 11 outward bulge of thread hollow rivet
It rises and forms heading, complete riveting.Riveting process can pass through the observation scale variation understanding screw rod 9 at windowing 4 windowing of swivel nut
Stroke is conducive to control riveting quality.
It after completing riveting, pulls and rotates adjustable cap nut 6, make the hexagon ring and screw rod 9 on adjustable cap nut 6
On hexagonal shaft part work good, rotate adjustable cap nut 6 and the rotation of screw rod 9 driven to exit thread hollow rivet.
Being can adjust between cap nut 6 and swivel nut 5 in rotary course is precessional motion.Only have front end portion to have on swivel nut 5
External screw thread, screw thread are higher than non-threaded section of outer rim, have one section of cavity area, and cavity zone before adjustable 6 internal screw thread of cap nut
Domain is greater than the threaded portion on swivel nut 5, and adjustable cap nut 6 is made to can adjust cap nut 6 afterwards to a certain degree being screwed into swivel nut 5
It is detached from, can not be rotated freely with influencing by swivel nut 5 with 5 external thread section of swivel nut, that is, can guarantee that adjustable cap nut 6 has foot
Enough rotation amounts.
10 threaded portion of special type screw nut is mounted on adjustable cap nut 6, and another part internal diameter is less than on swivel nut 5
The big warp of thread segment can prevent from leading to adjustable cap nut 6 and swivel nut 5 when rotating adjustable cap nut 6 after staking
It is detached from
By embedded connection, screw rod 9 can be replaced into the screw rod of diameter, sample different in size for screw rod 9 and adapter 27, with
Meet the thread hollow rivet 11 of different-diameter, length.
It is plane, tapered two kinds of specifications that adjustable cap nut 6, which has front end, meets different type thread hollow respectively
The needs of rivet.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
