Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.
Specifically, the purpose of this utility model, accurately on basis, provide a kind of simple and easy, adjustable, floating type marking fixture in guarantor's font rocking arm die forging blank line and assay, utilize face plate, line slide calliper rule, marking gauge realize three-dimensional line fast and check.
As shown in Figure 1 and Figure 2, a kind of line and inspection jig of herringbone rocking arm rough forging, comprising: clip base and be located at location, clamping, the element floating support device on matrix.Described positioner comprises two 120 ° of V-type locating pieces 6 and the locating piece (3) of two forks of fixing described herringbone rocking arm, described clamping device comprises the first rotary pressing plate (4) of fixed body and by screw and the fixing pressing plate (7) of matrix phase, described element floating support device comprises floating support (5).
Further, preferably, one end of described matrix is provided with activity point of view location-plate (2), and fixed head is provided with fastening screw 9.
Further, preferably, between two 120 ° V-type locating pieces (6), be provided with adjustment screw (8).
Wherein, as shown in Figure 3, three-dimensional marking fixture structure and principle are as follows:
The center line that generally selects important hole is line benchmark, and therefore the line benchmark of herringbone rocking arm is taking the center line of rocker shaft hole as the thick benchmark of line.On workbench, there is relocatable marking fixture as on-fixed, by adjusting, upset locating surface, ensure each station line key element and face plate maintenance level, rule with marking gauge, the small tools such as slide calliper rule of ruling.
Select at the Rigidity and strength of fixture, the general heavily about 15Kg of herringbone rocking arm single-piece, marking fixture should be lightweight, has again enough large Rigidity and strength, so clamp body material adopts ZL105, annealed processing, band reinforcing rib structure, has lightening hole.
Wherein, in order to ensure manufacturability and the stability of clamp structure
1 adopt multistation, turning, can float and adjust the positioning and clamping mechanism of angle.
2 parts fixations on marking fixture time, when upset line, are unlikely to overturning.
3 parts fixations are on marking fixture time, and when upset, part is unlikely to get loose.
When 4 three-dimensional line, clamp body, location and clamping element can not be interfered the line of line slide calliper rule.
5 fixtures are convenient to lifting.
Wherein, as Fig. 3 key element of all ruling is divided the size of doing in five directions:
1. the size a size on fore-and-aft direction;
2. the size b size on above-below direction;
3. the size c size on left and right directions;
4. the size e size on α angle direction;
5. perpendicular to the size f size on α angle direction;
Wherein, if Fig. 4 is as shown in Fig. 5 a, Fig. 5 b, herringbone rocking arm blank quality is to mach quality risk:
Axial plane deflection in 1 blank, easily causes the quality risk that inclined oil hole of air side penetrates or local hole wall is excessively thin.
The upper and lower deflection of 2 blank cross section, easily causes screw in compression face or jacking hole face there is no allowance.
The risk that inclined oil hole of air side penetrates or local hole wall is excessively thin, toward a lateral deviation, is easily caused in 3 blank longitudinal sections.
Wherein, operating procedure of the present utility model is as follows:
Clamp body is not first installed activity point of view location-plate 2.First, herringbone rocking arm is located with V-type locating piece 6 and positioning support 3, then, screw floating support 5, compress rotary pressing plate 4 and pressing plate 7 carry out fastening, start line: first mark the center of rocker shaft hole with marking gauge at rocking arm large end face, mark respectively above-below direction b dimension line; Turnover fixture, then from draw single armed one end separated time, mark respectively fore-and-aft direction a dimension line; Turnover fixture, marks left and right directions c dimension line; Mark θ line by marking gauge and point coordinates, extend two middle separated times that mark both arms.
Locate fast with fastening screw 9, activity point of view location-plate 2 is installed, turn adjustment screw 8, lifts clamp body right-hand member, with line slide calliper rule levelling A face, marks single armed end bulb bottom surface line f; Be positioned on face plate with angle orientation plate 2, mark the dimension line e on α angle direction.
Wherein, due to not necessarily final preferred result of initial volumetric line, allowance reasonable distribution is named again and borrow material, thereby ensure that processing exempts from out or go out less waste product, therefore when every batch of initial workpiece solid is rule, if there is the inhomogeneous situation of blank, judge quality risk according to line result, determine and adjust the principle of thick benchmark and proofread and correct line.
If line shows: the dimension line unification of workpiece moves towards a lateral deviation, and side-play amount is a, while drawing thick benchmark, can borrow in the opposite direction size a by thick reference center dimension line.
If line shows: only the center size of two bulbs of both arms end is moved towards a lateral deviation, and side-play amount is a, while drawing thick benchmark, can borrow in the opposite direction size a/2 by two bulb center dimension lines, judge that whether blank allowance is enough.
If line shows: the upper surface allowance of two bulbs of blank both arms end is too small, thick the level on large end face datum line is adjusted accordingly, take into account simultaneously and consider whether adjustment amount affects the allowance of single armed end bulb lower surface.
If line shows: the upper surface allowance of two bulbs of blank both arms end is little, and single armed end bulb lower surface allowance is large, the thick pad of each pad 1~2mm under both arms end bulb, otherwise, at the thick pad of single armed end bulb lower surface pad 1~2mm.
Beneficial effect of the present invention:
By field adjustable with reach the follow-up investigation of a year, this three-dimensional line inspection jig, about 20~30 minutes, can rule, check the blank quality of a herringbone rocking arm, not only location, clamping, upset are reliable, and detect accurately, can predicting machine allowance before machined whether enough, can also borrow material line, the quality risk of scrapping by the gross in prevention batch production, has application and preferably promotional value more widely.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
