Description
Technical field
The utility model belongs to aluminum-alloy wheel manufacture field, relates to horizontal lathe workpiece chuck, especially a kind of aluminum-alloy wheel machined six point location structure.
Background technology
At present, along with the fast development of auto industry, wheel product order volume constantly increases, and more strict to the balance requirement of product, after machining, product more often occurs that the overproof problem of balance causes waste product to the product that existing processing method is produced, and production efficiency is also lower, find by searching reason, mainly during machined now, the chuck locate mode of wheel product causes the machining center positioning precision of product not enough.
Existing blank footpath locate mode, locate to for locating inside outer rim with outside, adopt the locate mode of 3 cylinder manual adjustments, mainly there is following problem: (1) three blank thin-walled location, blank earflap radial force, blank deflection is comparatively large, affects the properties of product after machining accuracy and processing; (2) three locating pieces adjust radial position manually, there is certain error, cannot ensure that in order to ensure easily to be installed, leave certain gap with one heart between locating piece and blank at 3, cause being matched in clearance between locating piece and black skin; (3) 3 locating piece shapes are cylindrical, locate mode is 3 point locations, radial position is adjusted by the artificial mode by playing table, cannot guarantee to be distributed on a reference circle, there is certain error, cannot ensure that three anchor points are concentric, locating dowel decentraction state blank still can be installed, and causes blank and lathe spindle decentraction.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide that a kind of structure is simple, simple operation, safe and reliable, high-quality and high-efficiency aluminum-alloy wheel machined six point location structure.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of aluminum-alloy wheel machined six point location structure, in the workpiece chuck of lathe, radiai adjustment is provided with three these location structures, location structure specifically comprises positioning seat, guide groove, sleeve, locating dowel and spring spindle, positioning seat is a cube structure, this positioning seat upper end bilateral symmetry is shaped with gathering sill, the positioning seat of the radial one end of chuck is shaped with and through hole is installed and the positioning seat of this through hole upper end is shaped with/is fixed with a vertical sleeve, coaxial package locating dowel in this sleeve, this coaxial elastic top in locating dowel lower end is equipped with a spring spindle, it is characterized in that: the main body of described locating dowel is cylindrical structure, this main body upper end is coaxially installed with the positioning cap of a cube-shaped structure by screw, positioning cap upper end embeds in the detent of blank locating surface, lower body part is coaxially shaped with a blind hole, and in main body lower end two, lateral wall symmetry is shaped with spacing convex shoulder, spacing convex shoulder is inlaid in the installation through hole of the made similar shape in positioning seat lower end.
And this positioning cap cross section described is isosceles trapezoidal structure, two isosceles sidewalls of positioning cap hold out against blank locating surface respectively and form anchor point.
And described sleeve diameter is less than spacing convex shoulder, thus the spacing convex shoulder limiting card of both sides is made to be contained in sleeve lower end.
Advantage of the present utility model and good effect are:
1,3 locating piece force analysis of the present utility model are actual is that 6 heavy walls are located, blank earflap circumferencial direction is stressed, and blank wall locate mode deflection is little, promotes machining accuracy, the impact of reduce engine processing on product.
2,3 locating pieces of the present utility model are 6 point locations, and this locate mode blank breach two side-locating face freely coordinates with radial location block two side-locating face, until paste dead, guaranteeing that between blank locating surface and radial block locating surface, gapless exists, is interference fit.
3,3 locating piece shapes of the present utility model are trapezoid block, locate mode is 6 point locations, after radial position operator is installed according to wheel size adjustment, if blank and locating piece decentraction, locating notch on blank and radial location block stagger, and blank just cannot be installed, and radial location block has certain self-centering function, 6 anchor points, on identical graduation circle, are effectively guaranteed with one heart.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of aluminum-alloy wheel machined six point location structure, in the workpiece chuck of lathe, (attached not shown chuck) radiai adjustment is provided with three these location structures, location structure specifically comprises positioning seat 1, guide groove 2, sleeve 3, locating dowel 4 and spring spindle 5, positioning seat is a cube structure, this positioning seat upper end bilateral symmetry is shaped with gathering sill, the positioning seat of the radial one end of chuck is shaped with and through hole is installed and the positioning seat of this through hole upper end is shaped with/is fixed with a vertical sleeve, coaxial package locating dowel in this sleeve, this coaxial elastic top in locating dowel lower end is equipped with a spring spindle.
The main body 403 of described locating dowel is cylindrical structure, this main body upper end is coaxially installed with the positioning cap 402 of a cube-shaped structure by screw 401, this positioning cap is isosceles trapezoidal structure, positioning cap upper end embeds in the detent of blank locating surface, two isosceles sidewalls of positioning cap hold out against blank locating surface respectively and form anchor point, namely each positioning cap all forms 2 point locations supports, and lower body part is coaxially shaped with a blind hole, is shaped with spacing convex shoulder 404 in main body lower end two lateral wall symmetry; Spacing convex shoulder is inlaid in the installation through hole of the made similar shape in positioning seat lower end, and locating dowel cannot be rotated.
Sleeve diameter is less than spacing convex shoulder, thus makes the spacing convex shoulder limiting card of both sides be contained in sleeve lower end, cannot move up, when locating dowel be under pressure be absorbed in positioning seat inner time, spring spindle force makes locating dowel reset.
This structure location schematic diagram is Figure 4 shows that see attached, structure upper end is wheel blanks product, the small gap of three sizes, deep equality is shaped with at blank locating surface radial equipartition, the cross sectional shape of small gap is trapezoidal, and during location, location structure is corresponding respectively to be embedded in a breach, blank compresses 3 location structures under gravity and forms 6 supports, make to offset, stablize mounting structure, promote positioning precision; See the attached location structure that Figure 5 shows that prior art.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
