Detailed description of the invention
In the detailed description of following embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
First see Fig. 1, be used for compressing being realized assembling by the weak rigid panels part 21 of the illustrative aircraft of dotted line according to the flexible pressing device of weak hard parts of the present invention.In illustrative embodiment, flexible pressing device comprise the part 21 that need connect or dock locate clamping clamp assembly 2, to connect or part 21 vertically compresses by joint that at least one holds down assembly 3 and regulate the displacement adjusting part 1 of 3 displacements of holding down assembly in the horizontal direction.Wherein, as shown in the figure, clamp assembly 2 adopts the form of positioning sucker disk, and the need being disposed in part 21 connect or the two ends of docking.Displacement adjusting part 1, for being set up in the pair of guide rails above clamp assembly 2, which is provided with guide groove 8.According to the length need assembling compression, at least one holds down assembly and 3 can move horizontally along guide groove 8 and carry out displacement switching, and is lock onto on displacement adjusting part 1 by the nut 11 such as shown in Fig. 2 and screw 12.
For realizing to weak hard parts 21 based on the compression requirement limiting assembling thrust scope, 3 fast-holdings being designed to realize in vertical direction that hold down assembly of the present invention.According to embodiment shown in figure, holding down assembly 3 is set to tubular, comprises housing 20 (Fig. 3), upper cover 5 and lower cover 7.Wherein, in housing 20, the first force application part arranged successively along force direction and the second force application part is provided with.As shown in Figure 2, the holddown spring 14 that first force application part comprises compact heap 9 and pressed down by upper compact heap 9, second force application part comprises the lower compact heap 10 offseted with holddown spring 14 and the jack-up spring 13 pressed down by lower compact heap 10, is connected to lower compact heap 10 to the compacting part 19 that part 21 is implemented to compress.In addition, be also provided with the axis of guide 15 extending to lower cover 7 from upper cover 5 in housing 20, holddown spring 14 and jack-up spring 13 are sheathed on the axis of guide 15 successively.In embodiment shown in the figure, be advantageously provided three axis of guides 15 be evenly arranged, sheathed holddown spring 14 and jack-up spring 13 all successively on each axis of guide 15.Those skilled in the art will be understood that the embodiment greater or less than three axis of guides 15 is also possible.Also can find out from figure, in order to contribute to force, hold down assembly 3 also comprise extend through upper cover 5 arrange pressing handle 4, it is threaded connection to upper cover 5, and promotes upper compact heap 9 via thrust roller bearing 16.When upper compact heap 9 pressurized, it downwards promotes holddown spring 14 along the axis of guide 15, and then promotes and lower compact heap 10 that holddown spring 14 offsets, descends compact heap 10 to compress jack-up spring 13 subsequently.Because lower compact heap 10 is subject to the downforce of holddown spring 14 and the jack-up power of jack-up spring 13 simultaneously, it produces with the floating displacement that pressure is associated and is applied on part 21 by balanced pressure by compacting part 19, meets weak hard parts 21 thus based on the compression requirement limiting assembling thrust scope.
As can be seen from Fig. 1, hold down assembly 3 housing 20 outer wall on be provided with dial 6 and be provided with along dial 6 arrange slit 22, accordingly, upper compact heap 9 and lower compact heap 10 are respectively equipped with the pointer 17,18 passing slit 22, thus operator can simple, intuitive ground by the shift position of compact heap in visualization 9 and lower compact heap 10, and learn corresponding force value by pointer 17,18 scale value corresponded on dial 6, realize the control to part 21 thrust.
When the assembling adopting above-mentioned flexible pressing device to implement part compresses, can carry out according to the following steps:
A, the calibration of use mechanics apparatus hold down assembly, and can determine upper compact heap and the corresponding shift value of lower compact heap on dial according to different thrust simultaneously;
B, the need by clamp assembly flexible pressing device being fixed on weak hard parts are connected or the two ends of docking;
C, visually need the length of compacted position at least one to be held down assembly to be positioned on displacement adjusting part, the position held down assembly described in adjustment is also locked;
The upper compact heap held down assembly described in d, compression, holddown spring is compressed under the active force of upper compact heap and produces elastically-deformable thrust, and then compress lower compact heap and jack-up spring, until the shift value of upper compact heap and lower compact heap meets force request, now, upper compact heap assembles thrust with the corresponding target of position difference of lower compact heap;
The thrust numerical value of compact heap and lower compact heap on e, record, completes the compression of weak hard parts when assembling.
In aforesaid operations method, the practical set obtaining each compacted position by pointer 17 and the indication range of pointer 18 compresses force value, and the compression force value that controls can be judged whether in the scope required by the difference of visual pointer scale, the adjustment of stress value when compressing, with stress requirement during satisfied assembling.Simultaneously, balance is reached by the interaction of the clamping force of holddown spring 14, the jack-up active force of jack-up spring 13, when being subject to unexpected compression impulsive force, carry out cushion impact forces by the mutual opposition between spring, effectively prevent the destruction of causing when compacted part was subject to loading force.
Technology contents of the present invention and technical characterstic have disclosed as above, should be understood that, above-mentioned embodiment exists many alter modes, and these modes are clearly concerning various equivalent modifications.These amendment/modification fall into association area of the present invention, also should be included in the scope of appended claim.
