Description
Technical field
The present invention relates to fastener installation tool, particularly relating to for installing from boring the instrument of attacking firmware of riveting tightly.
Background technology
Existing conventional securing member has self-tapping screw, riveting nut etc., the easy stripped thread of self-tapping screw, and bonding strength is low, safety coefficient is low; And riveting nut outer ring does not have silk mouth, can not hole in front end, and need during installation first with instrument boring, then rivet with another set of instrument, finally exited by instrument, its operation is more, installs inconvenient, and boring and riveted joint needs two overlap different instruments, add cost.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides the instrument of attacking firmware of riveting tightly for installing oneself brill that a kind of structure is simple, easy to operate, installation effectiveness is high.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
For installing from boring the instrument of firmware of riveting tightly of attacking, comprise can with described from bores screw rod that the control screwed hole of attacking firmware of riveting tightly is threaded and can push in described from bore attack firewire port place of riveting tightly push part, described screw rod is connected with the described part that pushes.
The tail end of described screw rod is fixedly connected with the described part that pushes, and the length L of described screw rod is less than the degree of depth D of described control screwed hole.
The described part that pushes is sheathed on outside described screw rod, described in push part and be connected with described screw flight.
One end of described screw rod is provided with thrust boss, described in push part and be provided with the concave station coordinated with described thrust boss.
Compared with prior art, the invention has the advantages that:
It is of the present invention for installing from boring the instrument of attacking firmware of riveting tightly,
Fastener body outer peripheral face is provided with can age of a draught animal of tapping, fastener body one end is drilling portion, the other end is riveting sleeve, be provided with between drilling portion and riveting sleeve and can order about the boring of drilling portion, age of a draught animal tapping, the control part of riveting sleeve distortion riveted joint, during mounting fastener, fastener body can be ordered about with the instrument coordinated with control part to rotate, thus can directly be holed on workpiece by drilling portion, and utilize age of a draught animal tapping on hole wall, after age of a draught animal tapping, securing member is formed with workpiece and is threaded, and the rotation limited between securing member and workpiece and freedom of axial movement, after this instrument be convenient to by coordinating with control part orders about riveting sleeve and is out of shape, complete the riveted joint of securing member and workpiece, in installation process, no longer need to punch on workpiece in advance with specific purpose tool, simplify installation steps, substantially increase installation effectiveness, and make the riveted joint of securing member and workpiece convenient.Control part is screwed hole, can transmitting torque by coordinating with screw rod instrument, and then orders about the boring of drilling portion, age of a draught animal tapping; Simultaneously can also transmit pulling force by screw rod instrument, and then order about riveting sleeve distortion riveted joint, its structure is simple, be convenient to make processing, install easy to operate.Riveting sleeve comprises positioning cap and thin segment, can produce distortion when riveting sleeve is subject to axial extruding force, and the thin segment after distortion is by riveting workpiece with coordinating of positioning cap, and its structure is simple, reliability is high.In the endoporus of riveting sleeve, also filling reinforcement can be set, to improve the shear resistance of securing member, and improve the bonding strength to workpiece.

Detailed description of the invention
Fig. 1 and Fig. 2 shows of the present invention a kind of for installing from boring the device embodiment of attacking firmware of riveting tightly, this instrument comprise can with from bores screw rod 1 that the control screwed hole 31 of attacking firmware 3 of riveting tightly is threaded and can push in oneself bore attack firmware 3 port of riveting tightly push part 2, screw rod 1 with push part 2 and be connected, in the present embodiment, the tail end of screw rod 1 with push part 2 and be fixedly connected with, the length L of screw rod 1 is less than the degree of depth D controlling screwed hole 31.First screw rod 1 is screwed into when installing with this instrument certainly bore and attack and rivet tightly firmware 3 and rivets tightly in the control screwed hole 31 of firmware 3 from boring to attack, attack firmware 3 port of riveting tightly until push part 2 push against (as shown in step a in Fig. 2) with from boring, continue to apply moment of torsion to this instrument can order about and attack firmware 3 of riveting tightly hole on workpiece from boring, tapping, boring, after tapping, attack from brill firmware 3 of riveting tightly to define be threaded (as shown in step b in Fig. 2) with workpiece, now further moment of torsion is applied to instrument, screw rod 1 will be engaged further with control screwed hole 31, form the axial compression to attacking firmware 3 of riveting tightly from brill, making to attack from brill firmware 3 of riveting tightly is out of shape workpiece riveted joint (as shown in step c in Fig. 2), after this, screw rod 1 can exit (as shown in steps d in Fig. 2) from from boring to attack the control screwed hole 31 of firmware 3 of riveting tightly by reversion instrument, from boring the installation of attacking firmware 3 of riveting tightly, in whole process, only need apply moment of torsion by instrument to attacking from brill firmware 3 of riveting tightly, simple to operate, can greatly improve securing member installation effectiveness.
Fig. 3 and Fig. 4 shows another kind of the present invention for installing from boring the device embodiment of attacking firmware of riveting tightly, the present embodiment is substantially identical with a upper embodiment, difference is only: the part 2 that pushes of this instrument is sheathed on outside screw rod 1, push part 2 to be threaded with screw rod 1, one end of screw rod 1 is provided with thrust boss 11, push part 2 and be provided with the concave station 21 coordinated with thrust boss 11, screw rod 1 other end stretches out and pushes part 2.With this instrument install from bore attack rivet tightly firmware 3 time, first screw rod 1 is threaded with from boring the control screwed hole 31 of attacking firmware 3 of riveting tightly, attack firmware 3 port of riveting tightly until push part 2 push against (as shown in step a in Fig. 4) with from boring, continue to apply moment of torsion to this instrument can order about and attack firmware 3 of riveting tightly hole on workpiece from boring, tapping, boring, after tapping, attack from brill firmware 3 of riveting tightly to define be threaded (as shown in step b in Fig. 4) with workpiece, now apply moment of torsion to pushing part 2 further, the screw thread lift pushed between part 2 and screw rod 1 will be delivered to by screw rod 1 to be riveted tightly on firmware 3 from boring to attack, form the axial compression to attacking firmware 3 of riveting tightly from brill, making to attack from brill firmware 3 of riveting tightly is out of shape workpiece riveted joint (as shown in step c in Fig. 4), after this, reversion pushes part 2 and screw rod 1 can be exited (as shown in steps d in Fig. 4) from from boring to attack the control screwed hole 31 of firmware 3 of riveting tightly, from boring the installation of attacking firmware 3 of riveting tightly.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.Should propose, for those skilled in the art, improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
