Abstract
The utility model provides a molded surface hold-down device. The molded surface hold-down device comprises a pressing plate, a supporting leg, a connecting rod and a hold-down assembly, wherein the supporting leg, the connecting rod and the hold-down assembly are arranged on the pressing plate in a connected mode. The molded surface hold-down device is characterized in that the upper portion of the connecting rod is fixedly connected in a strip-shaped connecting hole of a connecting plate in a matched mode through a washer with a conical surface and a spherical washer. The hold-down assembly comprises a compression bar and a presser foot. The compression bar is fixedly connected to the pressing plate through a connecting piece. The presser foot is movably and universally connected to the lower end of the compression bar in a spaced mode. The molded surface hold-down device can realize compression on molded surfaces different in curvature.
Description
Technical field
The utility model relates to employed hold down gag in the airplane parts production, compresses in particular for the deep camber profile.
Background technology
In the manufacturing of airplane parts, for retaining element, assurance machining accuracy, must adopt suitable compression mode.Airplane parts is numerous and jumbled, and seal face is that the part machinery on plane adds man-hour, can adopt the flat clamp combination of dimension to compress, and reaches instructions for use.But, be the part of on-plane surface profile for seal face, adopt flat clamp to compress not only that area is little, thrust is not enough, and might with the crimp of part profile, cause part to scrap, particularly the part of deep camber profile.Usually adopt special pressing plate for this type of pressing plate, namely use the profile pressing plate that matches with the part profile.This pressing plate can well be fitted with part, and thrust is enough, and can not make part deformation.During its concrete use, the profile of each compacted position is different, and institute's use pressing plate is different, and for the part of large scale, complex profile, pressing plate can not be made in batches, and the manufacturing cycle of pressing plate is long, cost is high.And in the use procedure of pressing plate, the position of each pressing plate is fixed, if pressing plate is detachable, can cause pressing plate to obscure use, can make part deformation equally, uses very inconvenient.For the product of this small lot batch manufacture of aircraft, the versatility of special pressing plate is poor, and utilization rate is low, has increased the cost of part processing, has reduced production efficiency.
Summary of the invention
Use the problem complicated, that production efficiency is low, cost is high and versatility is poor in order to overcome existing profile hold down gag, the utility model provides a kind of deep camber profile hold down gag of Application standard spare combination, and versatility is good, and is easy to use, and cost is lower.
A kind of profile hold down gag, contain pressing plate and be connected to leg on the pressing plate, connecting rod to hold down assembly, the top that it is characterized in that described connecting rod is fixed in the strip connecting hole that is connected to connecting plate by a taper faced washer and a spheric washer, described holding down assembly contained depression bar and presser feet, depression bar is fixedly connected on the pressing plate by connector, and the universal gap of presser feet is connected to the lower end of depression bar.
The application's advantage is, the connecting rod of profile hold down gag by taper faced washer and spheric washer combination and pressing plate on the setting of bar hole, adjustment connecting rod that can be wider and link position and the connection angle of pressing plate, realization profile hold down gag is connected with frock; The presser feet of termination of holding down assembly is connected with depression bar is universal, realizes the compression to the different curvature profile.
Below in conjunction with the embodiment accompanying drawing the application is described in further detail.

Number description: 1 pressing plate, 2 legs, 3 connecting rods, 4 bar holes, 5 depression bars, 6 presser feets, 7 taper faced washers, 8 spheric washers, 9 profile parts, 10 frocks
The specific embodiment
Referring to accompanying drawing, the utility model deep camber profile hold down gag is by pressing plate 1, leg 2, connecting rod 3 and hold down assembly and form, hold down assembly and formed with the presser feet 6 that is movably connected in depression bar 5 terminations by the depression bar 5 that is fixed on the pressing plate, presser feet 6 and the flexible connection of depression bar 5 make the presser feet can be relative and the direction of depression bar termination flexible rotating presser feet, be a kind of universal connection, the direction variation of presser feet can effectively adapt to the surface applying maximization of electrolysis and the profile part 9 of presser feet; Connecting rod 3 also is a kind of universal connection with being connected of pressing plate 1, this universal connection realizes by connector, upper end at connecting rod is socketed by one group of taper faced washer that complements one another 7 and spheric washer 8, spheric washer 8 is crimped on the upside of taper faced washer 7, realize the direction adjustment of the relative pressing plate of connecting rod by the cooperation of spheric washer and taper faced washer contact-making surface, the connecting hole of pressing plate is a kind of hole of strip, can regulate the link position of connecting rod on pressing plate, the variation of the multi-direction and link position of connecting rod can effectively improve the adaptive of connecting hole on connecting rod and the frock, improves the versatility of the utility model in the processing of deep camber profile airplane parts.
