All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 to 6, the present invention provides a technical solution:
example 1:
a composite part processing technology based on a special-shaped complex curved surface gluing tool comprises the following steps:
s10, installing the glue joint tool 1: the glue joint tool 1 is clamped with the base 2 through the rapid fixing piece and the lug plate 3 on the glue joint tool;
s20, forming of the composite board: the outer skin, the inner skin and the honeycomb are glued and fixed on the gluing tool 1 to form a composite plate;
s30, replacing a forming tool: taking down the rapid fixing piece and separating the gluing tool from the base 2, arranging the forming tool at a position corresponding to the base 2, and clamping the rapid fixing piece and the lug plate 3 on the forming tool with the base 2;
s40, semi-forming of parts: laying the composite board, and half-forming the part when the thickness requirement is met; the two adjacent composite plates are glued;
s50, curing the part: and (5) putting the semi-formed part in the step (S40) into a vacuum furnace for curing, and obtaining a formed part after curing.
Further, the gluing tool 1 comprises a tool body 4 for supporting parts and a pressing member 5 for fixing the parts. The specific structure is shown in the figure and is not described herein.
Further, as shown in fig. 1 to 6, a T-shaped fixing groove 6 is formed in the base 2, the quick fixing element includes a pressing cap 7, a connecting column 8 and an expanding rod 9, one end of the connecting column 8 is fixed to the pressing cap 7, and the other end of the connecting column 8 extends into the bottom of the fixing groove 6; through holes 10 are formed in the middle parts of the pressing cap 7 and the connecting column 8, and the expansion rod 9 is arranged in the through holes 10;
wherein the pressing cap 7 and the connecting column 8 are of an integrated structure.
At least two abdicating grooves 11 communicated with the through holes 10 are uniformly distributed at one end of the connecting column 8 extending into the fixing groove 6 along the circumferential direction, a slidable trapezoidal clamping sheet 12 is arranged in each abdicating groove 11, and a return spring 13 is arranged between each trapezoidal clamping sheet 12 and the connecting column 8;
when the expansion rod 9 extends into the through hole 10 and is fixed, the trapezoidal clamping sheet 12 extends out of the abdicating groove 11 and the protruding part of the trapezoidal clamping sheet 12 is clamped with the fixing groove 6.
The inclined planes of the two trapezoidal clamping sheets 12 are oppositely arranged, and the end part of the expansion rod 9 is of an inverted cone structure matched with the inclined planes of the trapezoidal clamping sheets 12.
The inner wall of the through hole 10 is provided with internal threads, external threads are arranged outside the expansion rod 9, and the expansion rod 9 is in threaded connection with the through hole 10.
When the connecting column 8 extends into the fixing groove 6, the upper surface of the abdicating groove 11 is flush with the upper surface of the large-size part of the fixing groove 6.
Here, the fixation of the gluing tool 1 and the base 2 is explained:
(1) The splicing holes of the upper ear plates 3 of the splicing tooling 1 are vertically corresponding to the fixing grooves 6 on the base 2.
(2) The connecting column 8 extends into the fixing groove 6 through the inserting hole on the ear plate 3, and the lower surface of the pressing cap 7 is tightly attached to the upper surface of the ear plate 3; when the connecting column 8 enters the fixing groove 6, the trapezoidal clamping sheet 12 retracts into the through hole 10, so that the outer surface of the trapezoidal clamping sheet 12 is flush with the outer wall of the connecting column 8.
(3) The expansion rod 9 is inserted into the through hole 10, the expansion rod 9 is screwed, and the expansion rod 9 moves downwards in the screwing process of the expansion rod 9. During the descending process of the expansion rod 9, the trapezoidal clamping sheet 12 partially extends out of the abdicating groove 11 under the action of the inclined surface of the trapezoidal clamping sheet and the end part of the expansion rod 9, namely, the outer surface of the trapezoidal clamping sheet 12 protrudes out of the outer wall of the connecting column 8. When the expansion rod 9 is in place, the upper surface of the trapezoid clamping sheet 12 is tightly attached to the upper surface of the fixing groove 6, and the lower surface of the trapezoid clamping sheet 12 is tightly attached to the bottom surface of the receding groove 11.
At this moment, the glue joint tool 1 is fixedly connected with the base 2 under the action of the ear plate 3 and the quick fixing piece. When the male tool needs to be smoother, the expansion rod 9 is screwed reversely, and when the end part of the expansion rod 9 is positioned above the trapezoid clamping sheet 12, the trapezoid clamping sheet 12 is reset under the action of the reset spring 13 due to the fact that the limit function of the expansion rod 9 is not achieved. At this time, the connection state of the ear plate 3 and the base 2 can be released only by applying an outward pulling force to the quick fixing piece.
The lug plate 3 is clamped and fixed with the base 2 through the quick fixing piece, so that threaded connection is avoided, and the situation of thread failure cannot occur; the expanding rod 9 bears the acting force direction of the trapezoidal clamping sheet 12, namely the shearing force, along the radial direction, so that the expanding rod 9 cannot act on the internal thread, and the situation of thread failure at the through hole 10 cannot occur; the internal thread of the through hole 10 only plays a role in fixing the expansion rod 9, and the expansion rod 9 cannot bear axial force, so that the screwing length of the internal thread and the external thread can be set to be very short, and can be but not limited to 1/10 of the length of the expansion rod 9; the expansion rod 9 does not need to rotate for many circles when being fixed, and the tool mounting efficiency is improved.
Example 2:
the difference between this embodiment and embodiment 1 is that, as shown in fig. 6, a bolt 14 hole is provided on the pressing cap 7, the bolt 14 hole is communicated with the through hole 10, a fixing hole coaxial and communicated with the bolt 14 hole is provided on the expansion rod 9, and the expansion rod 9 is fixed by the fixing hole, the bolt 14 hole, and a pin after extending into the through hole 10.
When the tool is fixed, the other steps are the same as those in embodiment 1, except that the step (3) in embodiment 1: insert and expand opening rod 9 and target in place, when expanding opening rod 9 and target in place, the fixed orifices is coaxial with 14 holes of bolt, inserts bolt 14 this moment and can realize expanding opening rod 9's fixed, avoids expanding opening rod 9 to break away from through-hole 10 and lead to otic placode 3 and base 2's being connected inefficacy under the exogenic action.
So set up, after otic placode 3 aligns with base 2, only need three simple grafting action can realize the fixed of frock and base 2, further simplified the installation of frock, improved the installation rate of frock and base 2.
Example 3:
in this embodiment, on the basis of embodiment 1 or embodiment 2, as shown in fig. 6, a limit plate 15 is disposed at one end of the expansion rod 9 away from the fixing groove 6, and a hand-held ring 16 is disposed on the limit plate 15.
A hand ring is provided to facilitate rotation or insertion/removal of the expansion lever.
The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
