Abstract
The invention relates to a clamp for supporting an inner cavity in machining of large paddle beams. The clamp comprises a nut (1), a lead screw (2), an upper filler block (3), a lower filler block (4) and shoulder gaskets (5 and 6). The upper filler block (3) and the lower filler block (4) are each of a hollow structure, and are in a right trapezoid shape or right triangular shape; the bevel edge of the upper filler block (3) is matched with the bevel edge of the lower filler block (4); and the side face of the upper filler block (3) and the side face of the lower filler block (4) are each provided with a through hole (7). The lead screw (2) penetrates the through holes (7), and the shoulder gasket (5) is fixed to one end of the upper filler block (3); the shoulder gasket (6) is fixed to one end of the lower filler block (4); and the nut (1) is fixed to the shoulder gasket (6). The supporting clamp can ensure that in the machining process of the large paddle beams, the large beam inner cavity is supported; it is ensured that the large beam inner cavity does not collapse, and the assembling quality is ensured; and happening of the percent defective is reduced.
Description
Technical field
The present invention relates to frock clamp, particularly a kind of blade crossbeam adds the support fixture supporting crossbeam inner chamber man-hour.
Background technology
Blade crossbeam is the hollow crossbeam adopting D type aluminium alloy, its length dimension is 8054 ~ 8056mm, root inner chamber theoretical size 52.764mm ~ 54.434mm, requires in root end system 10 groups of holes, and the step of drilling is subdrilling just hole, reaming, slightly finish reams hole, coldworking strengthened hole, pressure bolts assemblies.All will exert pressure to crossbeam die cavity when coldworking strengthened hole and pressure bolts assemblies to cause crossbeam inner chamber to collapse chamber, causes product poor.At present direct at inner chamber by edge's pad one fabroil block.Because crossbeam inner chamber has tolerance, cause repairing file and repeatedly have a competition, just can find the fabroil block be highly applicable to, and when can only ensure to process the hole of edge, crossbeam does not collapse chamber, but during hole machined away from cushion block, the inner chamber in this region chamber of collapsing cannot stop.Have a strong impact on product quality and working (machining) efficiency.
Summary of the invention
The invention provides a kind of support fixture supporting main blade crossbeam inner chamber, comprise nut, leading screw, upper pad, lower pad, shoulder pad sheet, described upper pad and lower pad are hollow structure and shape is right-angled trapezium or right angled triangle, the hypotenuse of described upper pad and lower pad cooperatively interacts, there is through hole the side of upper pad and lower pad, and leading screw passes from through hole, and shoulder pad sheet is fixed on one end of pad, shoulder pad sheet is fixed on one end of lower pad, and nut is fixed on shoulder pad sheet.By the motion of leading screw and hold-down nut, pad and lower pad are moved and the upper and lower changing of the relative positions in the other direction.
This supports a kind of embodiment of the support fixture of main blade crossbeam inner chamber, also comprises catch and screw, and upper pad, lower pad both sides are provided with groove, and catch is fixed by screws on pad, and catch moves horizontally in groove.Catch ensure that the directed movement of pad and lower pad, laterally offset does not occur.
This supports a kind of embodiment of the support fixture of main blade crossbeam inner chamber, and upper pad and the long right-angle side of lower pad are provided with arc groove.Arc groove matches with main blade crossbeam inner chamber reinforcement, makes the motion in the other direction of upper pad and lower pad, serve when groove and main blade crossbeam inner chamber reinforcement recline completely the effect supporting main blade crossbeam inner chamber by adjusting screw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below the present invention is described in further details.See Fig. 1, a kind of support fixture supporting main blade crossbeam inner chamber, it is characterized in that, comprise nut 1, leading screw 2, upper pad 3, lower pad 4, shoulder pad sheet 5,6, upper pad 3 and lower pad 4 cooperatively interact and are hollow structure, and there is through hole 7 side of upper pad 3 and lower pad 4, leading screw 2 passes from through hole 7, shoulder pad sheet 5 is fixed on one end of pad 3, and shoulder pad sheet 6 is fixed on one end of lower pad 4, and nut 1 is fixed on shoulder pad sheet 6.Rotational lead screw 2, by the effect of nut 1, makes motion and the upper and lower changing of the relative positions in the other direction of pad 3 and lower pad 4.
See Fig. 1, the present invention also comprises catch 8,9 and screw 10, and upper pad 3, lower pad 4 both sides are provided with groove 11, and catch 8,9 is fixed on upper pad 3 by screw 10, and catch 8,9 moves horizontally in groove 11.By screw 10, catch 8,9 is fixed on after on upper pad 3, ensure that pad 3 and lower pad 4 are on the same face, and laminating is closely, when rotational lead screw 2 can not because of on pad 3 and lower pad 4 in opposite directions or relative motion and scattering.
See Fig. 1, upper pad 3 of the present invention and the long right-angle side of lower pad 4 are provided with arc groove.Rotational lead screw 2, by the effect of nut 1, upper pad 3 and the counter motion of lower pad 4, the height of support fixture is uprised, tighten when the muscle profile of groove and main blade crossbeam inner chamber fits and put in place, and ensure that the uniform force of support fixture, extend the service life of support fixture.
Using method of the present invention is: left hand is held lower liner and had one end of wing nut towards oneself and pinch wing nut with the right hand, the other end is inserted main blade crossbeam inner chamber and the groove of lower pad 4 and crossbeam inner chamber muscle are fitted and shift precalculated position onto, at this moment support fixture and crossbeam inner chamber have certain interval, drive upper pad 3 to move upward along the gradient of lower pad 4 by tightening wing nut, when wing nut is twisted motionless, upper liner 3, lower pad 4 recline with crossbeam inner chamber muscle and hold out against and locate.
