Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the present invention provides a positioning device for honeycomb forming. A mounting hole is opened outside the edge line of the part on the forming mold 1, and a step positioning pin 2 is installed in the hole. The upper part of the positioning pin 2 is sleeved in the hole of the positioning ring 3, and the positioning ring 3 is Metal parts with a "C" shape in the external section. The upper surface of the honeycomb 5 is bonded to the positioner 4 through the adhesive film 6, and the lower surface of the honeycomb 5 is bonded to the forming mold 1 through the adhesive film 6, so that the honeycomb 5, the mold 1 and the positioner 4 are bonded together, and the positioner 4 is a composite The material layer generally lays 2-3 layers, and the position of the positioning ring 3 needs to be multi-layered. The thickness of the layer is e...

Abstract

The invention belongs to the field of composite materials and provides a honeycomb forming positioning device. Positioning is accurate, and the service life is long. According to the technical scheme,a mounting hole is formed in the position, outside the part edge line, of a forming mould (1), a step positioning pin (2) is mounted in the hole, the upper portion of the positioning pin (2) is sleeved with a hole of a positioning ring (3), and the external section of the positioning ring (3) is in a C shape; a honeycomb (5) is placed on the mould (1), a positioning device (4) is a composite material layer, and the positioning ring (3) and the positioning device (4) are cemented; and the upper surface of the honeycomb (5) and the positioning device (4) are cemented through a glue film (6), and the lower surface of the honeycomb (5) and the forming mould (1) are cemented through the glue film (6).

Description

technical field [0001] The technology belongs to the field of composite materials, and relates to a positioning device and a using method during honeycomb forming. Background technique [0002] During the forming process of composite materials, in order to prevent the material from shifting during the material layering and pressurization curing process, it is necessary to use corresponding devices for positioning. The original positioning device is inaccurate in positioning, has a short life, and is prone to loosening. Contents of the invention [0003] Purpose of the invention: to provide a honeycomb forming positioning device with accurate positioning and long service life. [0004] Technical solution: a honeycomb forming positioning device, comprising: [0005] A mounting hole is opened outside the edge line of the upper part of the forming die (1), and a step positioning pin (2) is installed in the hole, and the upper part of the positioning pin (2) is sleeved in the ...
