Description
Technical field
the present invention relates to a kind of assembly method and equipment therefor of nut-washer combination part, belong to aviation securing member processing technique field.
Background technology
in the fasteners, general nuts and washers is matching used, and use is by packing ring pad between nut and fastener, and when screw on nut, packing ring generally can not rotate along with nut together, and can prevent when screw on nut, the seal face of nut spoils fastener.Nuts and washers as general service is all be separated usually.But at some special occasions, as manufacturing industry or the auto manufacturing of aerospace flight vehicle, owing to being subject to the restriction of installing space, the nuts and washers be separated brings many troubles to installation and maintenance, a kind of nut and packing ring is needed to link into an integrated entity, and can integrated nut-washer combination part in relative rotation between nut with packing ring.
current is adopt particular manufacturing craft to assemble by the method that packing ring and nut are assembled together, and is easy to extrude impression in assembling process on nut or packing ring.Make nut or packing ring produce defect, affect the reliability of securing member.
Summary of the invention
the object of the invention is to, a kind of assembly method and equipment therefor of nut-washer combination part are provided, to make to extrude impression on nut or packing ring in assembling process, can assembly quality be guaranteed, and guarantee the reliability of securing member, thus overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that the assembly method of a kind of nut-washer combination part of the present invention is that the method nut used is self-locking nut, and the contact jaw of nut and packing ring is provided with the frustum of a cone; Packing ring used is that plate-like packing ring is provided with annular flange; During assembling, six square ends of nut are clipped on the chuck of lathe, then the concave surface of packing ring is enclosed within the frustum of a cone end face of nut, the another side of packing ring is withstood with the push rod be arranged on tail stock, by being arranged on the lateral surface of the spinning roller spinning packing ring annular flange on lathe saddle, packing ring annular flange is made inwardly to produce permanent deformation, wrap on the frustum of a cone conical surface of nut, packing ring can not be come off into from nut and be integrated.
in preceding method, described in be arranged on spinning roller on lathe saddle and tilt to install, its tilt angle alpha is identical with the frustum of a cone tapering β of nut.
in preceding method, the described packing ring annular flange that makes inwardly produces permanent deformation, wrap on the frustum of a cone conical surface of nut, the radial clearance of the frustum of a cone conical surface of packing ring annular flange and nut is controlled by the amount of feeding being arranged on spinning roller on lathe saddle, does not come off to guarantee packing ring can be able to rotate on nut.
in preceding method, described in be arranged on push rod on tail stock and packing ring contact surface be provided with positioning boss, the diameter of positioning boss is corresponding with the diameter of bore of packing ring, and to prevent packing ring, on the top of spinning roller, pressure produces radial vibration.
said method equipment therefor of the present invention is: this device comprises lathe, and the tailstock of lathe is provided with push rod, and the knife rest of lathe is provided with spinning roller, and spinning roller is obliquely installed, and its tilt angle alpha is identical with the tapering β of the frustum of a cone on nut.
in preceding method, one end of described push rod is provided with positioning boss, and the diameter of positioning boss is corresponding with the diameter of bore of packing ring.
compared with prior art, the present invention adopts engine lathe to carry out the assembling of nut and packing ring, need not purchase special equipment and mold, can reduce production cost.Impression can not be extruded on nut or packing ring in assembling process, can assembly quality be guaranteed, guarantee the reliability of securing member.The inventive method is simple, produces low cost, easily implements.Be applicable to small lot to produce.

Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is described in further detail, but not as any limitation of the invention.
embodiment.An assembly method for nut-washer combination part, as shown in Figure 1, Figure 2 and Figure 3.The method nut 1 used is self-locking nut, and the compression end end of nut 1 is provided with the frustum of a cone 3; Packing ring 2 used is annular flange 4 for plate-like packing ring is provided with; During assembling, six side one end of nut 1 are clipped on the chuck 5 of lathe, then the concave surface of packing ring 2 is enclosed within the frustum of a cone 3 end face of nut, the another side of packing ring 2 is withstood with the push rod 6 be arranged on tail stock, push rod 6 is provided with positioning boss 8 with the contact surface of packing ring, the diameter of positioning boss 8 is corresponding with the diameter of bore of packing ring, and to prevent packing ring 2, on the top of spinning roller 8, pressure produces radial vibration.By being arranged on the lateral surface of the spinning roller 7 spinning packing ring annular flange 4 on lathe saddle, the spinning roller 7 be arranged on lathe saddle tilts to install, and its tilt angle alpha is identical with the frustum of a cone 5 tapering β of nut.Annular flange 4 relative scrolling realization spinning packing ring annular flange 4 under the pressure of spinning roller 7 of packing ring 2, packing ring annular flange 4 is made to be contained within the object of the circular cone table top of nut 1, make packing ring annular flange 4 inwardly produce permanent deformation, wrap on the frustum of a cone 3 conical surface of nut.Packing ring annular flange 4 is controlled by the amount of feeding being arranged on spinning roller 8 on lathe saddle with the radial clearance of the frustum of a cone 6 conical surface of nut, the nut-washer combination part assembled as shown in Figure 4, does not come off to guarantee packing ring 2 can be able to rotate on nut 1.Packing ring 2 can not be come off into from nut 1 be integrated.
realize the device that preceding method is used, comprise lathe, the tailstock of lathe is provided with push rod 6, and one end of push rod is provided with positioning boss 8, and the diameter of positioning boss 8 is corresponding with the diameter of bore of packing ring.The knife rest of lathe is provided with spinning roller 7, and spinning roller 7 is obliquely installed, and its tilt angle alpha is identical with the tapering β of the frustum of a cone on nut 3.
