Abstract
The utility model discloses a nut composite pieces assembling device which comprises a lathe. An ejector rod (6) is arranged on the tail seat of the lathe. A knife frame of the lathe is provided with a spinning idler wheel (7) arranged in an oblique mode. The oblique gradient alpha of the spinning idler wheel is equal to the conical degree beta of a cone-shaped platform (3) on the nut. The lathe is ordinary and used to assemble the nut and the flange so that dedicated equipment and molds do not need purchasing and the production cost is reduced. The nut or the flange is not pressed with indentation in assembly so that the quality of the assembly and the reliability of a fastener are ensured. The nut flange composite pieces assembling device has the advantages of being simple in method, low in production cost, easy to implement and suitable for production in small quantities.
Description
Technical field
the utility model relates to a kind of assembling equipment therefor of nut collar sub-assembly, belongs to aviation and uses the securing member processing technique field.
Background technology
in securing member, general nuts and washers is matching used, use be with the packing ring pad between nut and fastener; When screwing nut; Packing ring generally can not prevent that when screwing nut, the seal face of nut is spoilt fastener along with nut rotates together.The nuts and washers of using as general service all separates usually.But at some special occasions; Manufacturing industry or auto manufacturing like aerospace flight vehicle; Owing to receive the restriction of installing space; The nuts and washers that separates has brought many troubles to installation and maintenance, needs a kind of nut and packing ring to link into an integrated entity, and can integrated in relative rotation nut collar sub-assembly between nut and the packing ring.
The method that
at present are assembled together packing ring and nut is that the employing particular manufacturing craft assembles, and in assembling process, is easy on nut or packing ring, extrude impression.Make nut or packing ring produce defective, influence the reliability of securing member.
Summary of the invention
The purpose of
the utility model is; A kind of assembling equipment therefor of nut collar sub-assembly is provided,, can guarantees assembly quality so that in assembling process, can on nut or packing ring, not extrude impression; And guarantee the reliability of securing member, thereby overcome the deficiency of prior art.
The technical scheme of
the utility model is achieved in that the assembling equipment therefor of a kind of nut collar sub-assembly of the utility model does; This device comprises lathe; The tailstock of lathe is provided with push rod; The knife rest of lathe is provided with the spinning roller, and the spinning roller is obliquely installed, and the tapering β of the frustum of a cone is identical on its tilt angle alpha and the nut.
In
preceding method, an end of said 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 utility model adopts engine lathe to carry out the assembling of nut and packing ring, need not purchase specialized apparatus and mould, can reduce production costs.Can on nut or packing ring, not extrude impression in the assembling process, can guarantee assembly quality, guarantee the reliability of securing member.The utility model method is simple, and it is low to produce cost, is prone to implement.Being fit to small lot produces.

Being labeled as in
accompanying drawing: 1-nut, 2-packing ring, the 3-frustum of a cone, 4-annular flange, 5-chuck, 6-push rod, 7-spinning roller, 8-positioning boss.
The specific embodiment
are done further to specify to the utility model below in conjunction with accompanying drawing and embodiment, but not as any restriction to the utility model.
embodiment: the utility model is constructed according to the assembly method of following a kind of nut collar sub-assembly, and the used nut 1 of this method is a self-locking nut, and the compressing end end of nut 1 is provided with the frustum of a cone 3; Used packing ring 2 is annular flange 4 for the plate-like packing ring is provided with; Six sides, one end with nut 1 during assembling is clipped on the chuck 5 of lathe; Concave surface with packing ring 2 is enclosed within on the frustum of a cone 3 end faces of nut then; Use the push rod 6 that is installed on the tail stock to withstand the another side of packing ring 2; Push rod 6 is provided with positioning boss 8 with the contact-making surface of packing ring, and the diameter of positioning boss 8 is corresponding with the diameter of bore of packing ring, and string moves to prevent packing ring 2 under the roof pressure of spinning roller 8, producing radially.Through being installed in the lateral surface of the spinning roller 7 spinning packing rings annular flange 4 on the lathe saddle, the spinning roller 7 that is installed on the lathe saddle tilts to install, and its tilt angle alpha is identical with the frustum of a cone 5 tapering β of nut.The annular flange 4 of packing ring 2 is relative scrolling realization spinning packing ring annular flange 4 under the pressure of spinning roller 7; Make packing ring annular flange 4 be contained within the purpose 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 surfaces of nut.Packing ring annular flange 4 is controlled through the amount of feeding that is installed in spinning roller 8 on the lathe saddle with the radial clearance of the frustum of a cone 6 conical surfaces of nut; The nut collar sub-assembly that assembling is accomplished is as shown in Figure 4, does not come off to guarantee packing ring 2 on nut 1, can rotate.Packing ring 2 can not be come off from nut 1 to become one.
according to the assembling equipment therefor of a kind of nut collar sub-assembly of the constructed the utility model of said method do; This device comprises existing engine lathe; Like Fig. 1, Fig. 2 and shown in Figure 3; On the tailstock of lathe, be provided with push rod 6, an 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 the tapering β of the frustum of a cone 3 is identical on its tilt angle alpha and the nut.
Claims (2)
1. the assembling equipment therefor of a nut collar sub-assembly; Comprise lathe; It is characterized in that: on the tailstock of lathe, be provided with push rod (6); The knife rest of lathe is provided with spinning roller (7), and spinning roller (7) is obliquely installed, and the tapering β of the frustum of a cone (3) is identical on its tilt angle alpha and the nut.
