Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of truck drive shaft billiard table assembly 1, including interior billiard table 11, outer billiard table 12, described outer billiard table 12 is provided with spherical outside surface with interior billiard table 11 and rolls the Inner arc raceway groove coordinated, described outer billiard table at the press-in end inwall of interior billiard table circumferentially arranged with at least two slot-type openings 121.Slot-type openings 121 makes interior billiard table 11 can be press fit into smoothly in outer billiard table 12.
Wherein, described slot-type openings 121 is provided with two, circumferentially-spaced 180 degree of distributions of two slot-type openings billiard table inwalls outside.Two slot-type openings width are more than interior thickness of table 1mm, bottom grooved, installation site is less than interior billiard table external diameter 0.1mm, only arranging two grooveds 180 ° symmetrical and could be press fit in outer billiard table by ingenious for interior billiard table, grooved is provided with the magnitude of interference of 0.1mm, prevents interior billiard table from coming off after press-fiting.
The degree of depth of described slot-type openings 121 is 4.61mm, and the width of described slot-type openings 121 is 13.8mm, width side Sidewall angles is 5 °.The depth and width of slot-type openings and the design of Sidewall angles, main consideration is mated with interior billiard table 11, and grooved is too small, and product can not assemble, the intensity of the outer billiard table 12 of the excessive impact of grooved.
Described interior billiard table end face protrudes outer billiard table slot-type openings side end face, and the height of its protrusion is 0.3mm, and this design is to make outer billiard table 12 have better rotary oscillation angle, swinging effect more superior.
Power transmission shaft billiard table assembly design comparison is unique, processing precision of products requires height, outer billiard table is provided with two 180 ° of symmetrical slot-type openings, polish is intermittent grinding, difficulty of processing is big, form grinding Inner arc raceway groove roughness is adopted to ensure Ra≤0.25, spherical outside surface roughness Ra≤0.2, interior billiard table endoporus roughness Ra≤0.2.
Due to the particularity of product structure, adopting polish molding grinding technique, it is ensured that the machining accuracy of product, make interior billiard table arbitrarily can rotate swing at circumferencial direction by relatively outer billiard table after assembling, flexible performance is up to optimum state.
As shown in Figure 8, for the fit dimension of interior billiard table 11, outer billiard table 12, adopt following design:
(1) S φ d=((φ D-φ d)/2+d) × ρ
(2) { ((φ D-S φ d)/2)/((S φ d-φ d)/2)-1} × 100% > 7.5%.
S φ d: middle sphere diameter
Φ D: outer billiard table external diameter
Φ d: interior billiard table internal diameter
ρ: the coefficient of ratio (generally takes 0.9~0.98mm).
Design above formula is applicable to the product of interior billiard table internal diameter > φ 16mm to outer billiard table external diameter < φ 50mm.It addition, the size of above-mentioned slot-type openings is also suitable the product of this specification.
Outer billiard table is the parts that the present invention increases, and its applying working condition is more complicated, and material selects high intensity to have the Gcr15 of high-wear resistance, good fit with what reach with interior billiard table.
Above-mentioned truck drive shaft billiard table assembly processing technique: first outer billiard table is put into parallel desktop, outer billiard table slot-type openings is upward, then interior billiard table is perpendicular to desktop orientation and is put into outer billiard table slot-type openings place, the interior billiard table that will be perpendicular to is press-fited by the interference structure arranged, and assembles the flexible rotation performance checking inside and outside billiard table after putting in place.
Owing to outer billiard table is provided with slot-type openings, for this class formation, tradition is main adopts Milling Machining technique.But Milling Machining inefficient, cost is also high.Cold extruding formation process is adopted for this present invention.
The processing technique of outer billiard table is: the mill processing of forging rough turn phospholeum cold-extruded Vehicle Processing heat treatment.Wherein, forging, the processing of rough turn, phospholeum, heat treatment, mill are Conventional process steps, do not repeat them here, but for this step of cold extrusion forming, the present invention develops outer billiard table extrusion molding dies, for Vehicle Processing step, the present invention develops the tensioning clamper that external billiard table machines.
As shown in Figure 4, described outer billiard table extrusion molding dies 2 includes columned moulded head 21, the head of described moulded head is provided with the projection 22 being pressed into outer billiard table endoporus, and projection 22 diameter is less than moulded head 21 rear cylindrical body diameter, and described projection root is provided with the boss 23 for squeezing out slot-type openings.Moulded head, due in irregular shape, adopts three-dimensional modeling, and numerical control programming is input in process equipment to be shaped processing, moulded head material selection Japan imported L D mold materials.
As shown in Figures 5 to 7, described tensioning clamper includes cylindrical body 31 and the interior tension shaft 4 through cylindrical body 31, cylindrical body rear end is circumferentially with flange 32 around whole, flange is evenly distributed and arranges fixing hole 321, the head of described cylindrical body is provided with cone mouth 311, the head of described cylindrical body is circumferentially arranged with some dilatation joints 312, and the head of described cylindrical body is provided with the chucking lug 313 coordinated with slot-type openings 121.The head of interior tension shaft 4 is provided with annular boss 41, and described annular boss outer ring surface is provided with the conical surface 411 coordinated with cone mouth.The afterbody of interior tension shaft is provided with stud section 42, and annular boss 41 end face is provided with yi word pattern or cross fluting 412.
Cylindrical body 31 is fixed on lathe through fixing hole 321 on flange 32 by bolt, interior tension shaft 4 is fixed on the internal axially moving body of lathe by stud section 42, screwdriver drives interior tension shaft 4 to rotate by yi word pattern or cross fluting 412, thus stud section being fixed with moving axially body.Driving interior tension shaft 4 to move by moving axially body, the conical surface 411 acts on cone mouth 311, makes the head of cylindrical body 31 outer billiard table 12 tensioner be fixed, and now chucking lug 313 just coordinates with slot-type openings 121.
