Description
Technical field
The invention belongs to vehicle body field, refer to window track field, specifically refer to a kind of method for making of single-curvature face of cylinder formula guide rail of automobile side window glass lifting helix line.
Background technology
The form of the side window glass of current car, due to the demand of moulding, adopts the bicurvature shape face such as anchor ring or circle drum surface mostly.But double curved surface is because of the feature of its essence, the helix line cannot making the face of cylinder in single-curvature shape face realizes the lifting of glass for side window glass.Therefore, when designing side window glass guide rail, the bicurvature glass surface that moulding often will be relied on to provide simulates the face of cylinder of a single-curvature more again according to moulding constraint, thus helix line required when trying to achieve side window glass lifting, i.e. side window glass guide rail.
As shown in Figure 1 to Figure 3, existing technology is the side window glass guide rail according to moulding, former rail 21 and rear rail 22 are projected in a plane, then the position of plane is adjusted, former rail projection 23 and rear rail projection 24 are coincided together as much as possible, then a circle is become according to the track fitting overlapped
To stretch a face of cylinder by the normal direction of plane again, thus in the face of cylinder 26, draw the helix line 25 fitted with former rail and rear rail.The main points made take fitting circle the end of as, with the normal of plane for the high face of cylinder.
The shortcoming of existing technology is:
1. well can not overlap after guide rail projection before and after, often intersect, cause the face of cylinder of matching to be forbidden.
2. the adjustment that the adjustment of plane not can refer to guides, not only consuming time, and optimal case is difficult to obtain.
3. the former rail of styling step and rear rail, can not the actual jacking condition of actual response glass, and the scheme obtained also will be revised repeatedly.Such as two guide rails are not parallel, and its shape will be similar trapezoidal, be not up-narrow and down-wide are exactly wide at the top and narrow at the bottom, and glass loosely can locate getaway, and guide rail was lost efficacy.
Another kind of situation is, simulates a helix line according to B post (pillar in the middle of car door), adjustment glass in lifting process with the position in original bicurvature face, make the positional error in glass and bicurvature face as far as possible little.Main points during making are, 1, and as far as possible fitting with the helix line simulated of glass, and rely on this helix line to complete dipping and heaving; 2, glass, in dipping and heaving, is fitted with original bicurvature face as far as possible.
The shortcoming of this technical scheme is:
Only ensure that glass while fit with guide rail, glass another side cannot ensure, glass groove undue wear in lifting process that another side glass can be caused to match, affect glass dipping and heaving, reduce glass speed, even glass is toppled over or clamping stagnation, shortens the glass lifter motor life-span, and increases the other problem of glass jacking system.
The third situation is: adjustment glass in lifting process with the position in original bicurvature face, as shown in Figure 4, make glass fit with bicurvature face in the process, then draw up the track of glass two border in motion process, this track is glass guide-rail as far as possible as far as possible.The main points of this technical scheme are, 1, first have the movement position of glass, to ensure in glass motion process laminating bicurvature face as far as possible; 2, the path of motion of Glazed fence is gone out according to motion fitting.
The shortcoming of this technical scheme is:
Because the guiderail track simulated is not helix line, lifting irregularity can be made, cause Glazed fence and groove to cross quick-wearing.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, propose employing and make the face of cylinder of single-curvature crossing with the shape face of bicurvature, find out optimum two intersection lines, i.e. guide rails, then obtain the helix line of guide rail according to the face of cylinder of optimum again.
The present invention is achieved by the following technical solutions:
A method for making for automobile side window glass lifting guide rail,
Choose glass to be applied, four limits of described glass are closed with vehicle body appropriate section matching form, and two limits of matching with body movement direction with glass are for virtual preamble rail and rear rail;

The characteristic curve of B post is extracted according to the B column moulding of vehicle body;
In section, be initial point with mid point and connection features line in line, and does the normal plane of described straight line in midpoint within the scope of section;
The characteristic curve of B post projects and obtains a projection line on normal plane, described projection line is selected for a post meaning 3 and does circle, and with this circle for profile, is clearance line, does a face of cylinder with straight line;
By changing section mid point and the straight line of characteristic curve and the angle of characteristic curve, the face of cylinder of formation and the intersection position of glass surface and shape can be changed, make the characteristic curve of the intersection as far as possible border dummy guideway that laminating glass is relative with B post, determine shape and the position on the face of cylinder now, make the helix line of laminating B post characteristic curve;
Make the helix line of the same pitch on a glass border relative with B post according to the helix line of B post characteristic curve, these two helix lines are the advance decline line of glass;
Glass riser guide is produced according to advance decline line.
Described glass is bicurvature glass.
Measuring tool is utilized to measure an intersection laminating glass boundary characteristic relative with B post.
The length of the characteristic curve of the border dummy guideway that intersection laminating glass is relative with B post is at least greater than 2 times of glass height.
The invention has the beneficial effects as follows:
1. the technical program is based on the track of B post place guide rail, and do circle, and go to overlap with the track of another guide rail, easy standard, and purpose is strong, highly can meet design requirement as long as the crossover track of two curved surfaces and the length that overlaps of another guide rail meet the requirement that glass is elevated.
2. the technical program does not need projection, but utilizes existing condition to ask the work one single-curvature face of cylinder, and regulates the relative position relation of the glass of this face of cylinder and bicurvature, and reliability is high.
3. the single-curvature face of cylinder that the technical program is done intuitively can be found out with the crossing situation position of bicurvature glass surface from three-dimensional software (CATIA etc.), is convenient to the angle of guiding curve regulating the face of cylinder, directivity and workable.
4. the technical program can not only make the single-curvature face of cylinder needed for glass elevating screws line by fast speed, and accurate also very high.Compare with prior art, the precision improvement at Qianmen is about 10 times, and the precision improvement at back door is about 20 times.Both ensured that the track of forward and backward guide rail was helix line, make glass lifting process steady, again ensure glass in lifting process with bicurvature face laminating degree, the ultimate range in helix line and bicurvature face is no more than 0.05mm, side window glass is in lifting process, and the ultimate range in side window glass and bicurvature face is no more than 0.4mm.
