The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 to Fig. 6 shows the utility model for a kind of embodiment of the instrument that bores the firmware of riveting tightly, this instrument comprises a rotary drive 1 and a staking part 2, this rotary drive 1 can cooperate and realizes transfer of torque with the brill firmware 3 of riveting tightly, and then can order about when rotary drive 1 is rotated and bore firmware 3 rotary drillings of riveting tightly, staking part 2 can cooperate and bestows axial tension with the brill firmware 3 of riveting tightly, and then can bore the firmware 3 distortion riveted joints of riveting tightly by 2 extruding of control staking part.This instrument simple in structure, easy to make can make and bore firmware 3 rotary drillings of riveting tightly, and can push again and bore the firmware 3 distortion riveted joints of riveting tightly, and when installing drill is riveted tightly firmware 3, do not need the replacing instrument, greatly improved installation effectiveness.
In the present embodiment, rotary drive 1 is cutting ferrule, cutting ferrule is tubular, a tubular cutting ferrule in the inner end in hole is provided with two clamping boss 11, two clamping boss 11 are arranged symmetrically with respect to the center line of endoporus, brill is riveted tightly and is established the interface arrangment (for example can insert in two lug bosses 35 between the clamping boss 11) that cooperates with clamping boss 11 on the firmware 3, can realize transfer of torque, and then cutting ferrule is driven bore firmware 3 rotary drillings of riveting tightly.
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 the axial limiting assembly simultaneously between cutting ferrule and screw rod.The brill firmware 3 of riveting tightly is provided with the screwed hole 34 that cooperates with screw rod, after screw rod screws in screwed hole 34, can guarantee to bore the rivet tightly positioning stablity of firmware 3 reliable, is beneficial to and bores the installation of riveting tightly firmware 3.When the brill firmware 3 of riveting tightly is limited and can not rotates, and screw rod is fashionable to screwed hole 34 inward turnings, and screw rod is by the spacing pulling force that produces axially backward of axial limiting assembly, and then can push and bore the firmware 3 distortion riveted joints of riveting tightly.This kind becomes straight-line extruding form by rotation and only need adopt the power of rotation formula to get final product, and the required power of holing can be simplified the design of tool's power also for rotation formula, makes the structure of instrument more simple, cost is lower.The brill firmware 3 of riveting tightly can adopt as shown in Figure 2 structure, this brill firmware 3 of riveting tightly comprises and bores the firmware body 31 of riveting tightly, a rivet tightly end of firmware body 31 of brill is drilling section 32, the other end of firmware body 31 is the riveting sleeve 33 of crimp but brill is riveted tightly, the screwed hole 34 that cooperates with screw rod is opened in the bottom of riveting sleeve 33 endoporus, and the diameter of screwed hole 34 makes screw rod insert from riveting sleeve 33 endoporus and cooperates with screwed hole 34 less than the endoporus aperture of riveting sleeve 33.
In the present embodiment, the axial limiting assembly is the limited step 21 of being located on the screw rod, limited step 21 is positioned at the relative end of cutting ferrule and clamping boss 11 and offsets with cutting ferrule, the end that cutting ferrule and limited step 21 offset along endoporus week along being provided with concave ring groove, limited step 21 places in this concave ring groove.With after screwed hole 34 is connected, the effect by the axial limiting assembly can guarantee that cutting ferrule and the brill firmware 3 of riveting tightly offsets at screw rod, and then is convenient to the back and cooperates 33 distortion of screw extruding riveting sleeve.
The utility model for the instrument that bores the firmware of riveting tightly in use, the clamping boss 11 that makes first cutting ferrule and the brill firmware 3 of riveting tightly offsets, guarantee to bore simultaneously the clamping that cooperatively interacts of the interface arrangment of the firmware 3 of riveting tightly and clamping boss 11, cutting ferrule and the brill firmware 3 of riveting tightly can not be relatively rotated, the screw rod that then will be arranged in the cutting ferrule screws in screwed hole 34, screw rod screws in when extremely also having the position of a segment distance apart from screwed hole 34 bottoms, limited step 21 on the screw rod offsets with cutting ferrule, makes cutting ferrule be pressed in limited step 21 and brill rivet tightly (referring to Fig. 3) between the firmware 3.Cutting ferrule and screw rod are rotated together with brill rivet tightly firmware 3 in the pre-riveting position of workpiece 4 boring (referring to Fig. 4).After boring is finished, cutting ferrule is stopped operating, and screw rod continues to the direction of screwed hole 34 bottoms to screw in, because clamping boss 11 restriction makes and bores the firmware 3 of riveting tightly and can not rotate, can produce screw thread lift in the process that screw rod continues to screw in to the direction of screwed hole 34 bottoms, and then the riveting sleeve 33 that cooperates extruding to bore the firmware 3 of riveting tightly with cutting ferrule is out of shape and finishes riveted joint (referring to Fig. 5).After riveted joint was finished, screwed hole 34 was withdrawed from the screw rod reverse rotation, and cutting ferrule and screw rod are together taken out (referring to Fig. 6).
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should propose, for those skilled in the art, in the improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
