Problems solved by technology

However, the number of vertical walls is large, and multiple pillars need to be pasted on each vertical wall. It takes time and effort to locate the pillars one by one, and the pillars need to be fixed during the pasting process. The pillars are prone to slippage due to gravity or uneven external pressure. , resulting in a positional deviation

Embodiment 1

[0027] Example 1 A device for the edge line of J-shaped vertical wall return parts and positioning pillars

[0028] A device for returning part edge lines and positioning pillars of a J-shaped vertical wall. The main body of the device is formed by a formwork 1. The template is made of 1.5mm thick steel plate, and its material can ensure that the template is not easily deformed during use. The inner surface must fit the outer surface of the J-shaped wall. The outer contour of the template is the outer contour of the net size of the parts of the J-shaped longitudinal wall.

[0029] Such as figure 2 As shown, the template 1 is made into a Z shape. Such as image 3 As shown, the formwork supports an L shape.

[0030] The outer contour of the template 1 corresponds to the outer contour of the J-shaped vertical wall. Facilitates positioning between formwork and longitudinal walls.

[0031] The template 1 is provided with a longitudinal wall axis 2 and a longitudinal wall ri...

Embodiment 2

[0033] Embodiment 2 A method for returning parts edge lines and positioning pillars of J-shaped longitudinal walls

[0034] Utilize the described device of embodiment 1, method is as follows:

[0035] 1) if Figure 4 As shown, after the J-shaped longitudinal wall 7 and the skin 8 are glued together, they are sandwiched between the metal forming mandrel 5 and the rubber forming mandrel 6, and are cured together. After curing, the metal forming mandrel 5 and the rubber forming mandrel are removed. mod 6;

[0036] 2) Position the template 1 and the vertical wall 7, attach the above-mentioned device to the J-shaped vertical wall, and position the template 1 and the J-shaped vertical wall through the vertical wall axis 2 and the vertical wall rib line 3 to ensure that both Fit seamlessly, and then use adhesive tape to fix both ends of the template and the J-shaped vertical wall to ensure that the template and the J-shaped vertical wall do not move relative to each other during th...

Abstract

The invention relates to a device and a method for returning the edge line of a part and positioning struts for a J-shaped longitudinal wall. The technical scheme adopted by the invention is that after the J-shaped longitudinal wall, a skin and formed core molds are cured, the formed core molds are removed; the device is attached to the J-shaped longitudinal wall, a template and the J-shaped longitudinal wall are positioned through the axis and the rib line of the J-shaped longitudinal wall, no gap exists between the core mold and the J-shaped longitudinal wall, and then two ends of the template and two ends of the J-shaped longitudinal wall are fixed with an adhesive tape; the outer contour line of the J-shaped longitudinal wall is marked on the surface of the J-shaped longitudinal wall along the outer contour line of the template, and shape cutting is conducted on the J-shaped longitudinal wall according to the marked outer contour line of the J-shaped longitudinal wall; and positions in which the struts are to be pasted are scribed along strut assembly holes in the middle part of the template, and the struts are fixed by use of the template in the strut pasting process. The template provided by the invention has multiple functions of returning the net size lines of parts, positioning the struts, and preventing the slippage of the struts, and the work efficiency of shape cutting of the parts and the of strut pasting are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of composite material manufacturing, and relates to a device and a method for returning part edge lines and positioning pillars of a J-shaped longitudinal wall. In particular, it relates to a metal formwork used for positioning and fixing pillars when pasting pillars on vertical walls. At the same time, the template has the function of returning to the net dimension line of parts, which is convenient for the shape cutting of vertical walls in the later stage. Background technique [0002] At present, composite materials are one of the important indicators to measure the advancement of aerospace vehicles, and have been widely used in the manufacture of panel parts. The J-shaped longitudinal wall of composite material is the main load-bearing structure, which plays the role of supporting connection, participates in and transmits the load from the airfoil, and provides support for the airfoil at the same time. ...
