Detailed description of the invention
Below with reference to the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 to Fig. 6 shows the present invention for boring a kind of embodiment of the instrument of firmware of riveting tightly, this instrument comprises a rotary drive 1 and a staking part 2, this rotary drive 1 can coordinate with boring firmware 3 of riveting tightly the transmission realizing moment of torsion, and then brill can be ordered about when rotary drive 1 is rotated to rivet tightly firmware 3 rotary drilling, staking part 2 can coordinate with brill firmware 3 of riveting tightly and bestow axial tension, and then extrudes brill firmware 3 of riveting tightly be out of shape riveted joint by controlling staking part 2.The structure of this instrument is simple, easy to make, and brill can be made to rivet tightly firmware 3 rotary drilling, can extrude again brill firmware 3 of riveting tightly and be out of shape riveted joint, when installing drill rivets tightly firmware 3, not need replacing instrument, substantially increase installation effectiveness.
In the present embodiment, rotary drive 1 is cutting ferrule, cutting ferrule is tubular, one end that tubular is fastened in its endoporus is provided with two clamping boss 11, two clamping boss 11 are arranged symmetrically with relative to the center line of endoporus, boring rivets tightly on firmware 3 establishes the interface arrangment (such as can insert in the lug boss 35 between two clamping boss 11) coordinated with clamping boss 11, can realize the transmission of moment of torsion, and then cutting ferrule driving brill is riveted tightly firmware 3 rotary drilling.
In the present embodiment, staking part 2 is screw rod, and cutting ferrule is sheathed on the outside of screw rod, and it is simple and compact for structure, is provided with axial limiting assembly between cutting ferrule and screw rod simultaneously.Bore firmware 3 of riveting tightly and be provided with the screwed hole 34 coordinated with screw rod, after screw rod screws in screwed hole 34, can ensure to bore the rivet tightly positioning stablity of firmware 3 reliable, be beneficial to brill and rivet tightly the installation of firmware 3.When brill firmware 3 of riveting tightly is limited to rotate, and screw rod is fashionable to screwed hole 34 inward turning, and screw rod produces axially pulling force backward by axial limiting assembly is spacing, and then can extrude brill firmware 3 of riveting tightly and be out of shape riveted joint.This kind only needs to adopt the power of rotation formula from rotating the extruding form becoming rectilinear motion, and the power needed for boring is also rotation formula, can simplify the design of tool's power, make the structure of instrument more simply, cost is lower.Bore firmware 3 of riveting tightly and can adopt structure as shown in Figure 2, this brill firmware 3 of riveting tightly comprises and bores riveting fastener body 31, the one end of boring riveting fastener body 31 is drilling portion 32, the other end boring riveting fastener body 31 is can the riveting sleeve 33 of crimp, the screwed hole 34 coordinated with screw rod is opened in the bottom of riveting sleeve 33 endoporus, and the diameter of screwed hole 34 is less than the endoporus aperture of riveting sleeve 33, screw rod is inserted from riveting sleeve 33 endoporus and coordinates with screwed hole 34.
In the present embodiment, axial limiting assembly is the limited step 21 be located on screw rod, limited step 21 is positioned at cutting ferrule one end relative with clamping boss 11 and offsets with cutting ferrule, and one end that cutting ferrule and limited step 21 offset is along endoporus week along being provided with concave ring groove, and limited step 21 is placed in this concave ring groove.After screw rod is connected with screwed hole 34, can ensure that cutting ferrule and brill firmware 3 of riveting tightly offsets by the effect of axial limiting assembly, and then be convenient to rear side which fits screw extruding riveting sleeve 33 and be out of shape.
The present invention is for boring the instrument of firmware of riveting tightly in use, the clamping boss 11 of cutting ferrule and brill firmware 3 of riveting tightly first is made to offset, ensure to bore the rivet tightly interface arrangment of firmware 3 and clamping boss 11 to cooperatively interact clamping simultaneously, cutting ferrule and brill firmware 3 of riveting tightly can not be relatively rotated, then the screw rod be arranged in cutting ferrule is screwed in screwed hole 34, when screw rod screws in the position of a segment distance in addition to distance screwed hole 34, limited step on screw rod 21 and cutting ferrule offset, and make cutting ferrule be pressed in limited step 21 and brill rivets tightly (see Fig. 3) between firmware 3.Cutting ferrule is now made to rotate together with screw rod with boring pre-riveting position boring (see Fig. 4) of firmware 3 at workpiece 4 that rivet tightly.After having holed, cutting ferrule is made to stop operating again, and screw rod continues to screw in the direction bottom screwed hole 34, because clamping boss 11 restriction makes brill firmware 3 of riveting tightly not rotate, screw rod continues to the direction bottom screwed hole 34 can produce screw thread lift in the process screwed in, and then coordinates with cutting ferrule and extrude the riveting sleeve 33 boring firmware 3 of riveting tightly and be out of shape and rivet (see Fig. 5).After having riveted, screw rod reversely rotates and exits screwed hole 34, cutting ferrule and screw rod is together taken out (see Fig. 6).
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.
