Problems solved by technology

But at present, in the installation process of composite temporary fasteners, the mapping relationship between the installation air pressure and torque of pneumatic tools and the clamping force of composite temporary fasteners is not clear, and the installation can only be performed by the feeling of the installer , it is easy to have too large or too small clamping force; too large clamping force may cause damage to the hole wall and edge of the composite material parts, and bring hidden dangers to the mechanical load-bearing performance and fatigue life; while too small Clamping forces can easily cause play between thin-walled composite parts, affecting final assembly

Embodiment 1

[0049] In this embodiment, a composite material temporary fastener verification device is proposed, which can be used to accurately verify the mapping relationship between the installation process parameters of the air gun 6 and the clamping force generated by the composite material temporary fastener 16, so as to realize Accurate installation of composite temporary fasteners 16.

[0050] Specifically, such as figure 1 and figure 2As shown, the composite material temporary fastener verification device includes a base plate 1 , an air gun 6 capable of sliding on the base plate 1 , a torque sensor 12 , an installer 15 and a pressure sensor 19 . Wherein, the torque sensor 12 can slide on the base plate 1, and the output shaft of the torque sensor 12 and the air gun 6 is connected coaxially by the first coupling 9, and the torque sensor 12 is used to detect the torque of the output shaft of the air gun 6; Can slide on the base plate 1, one end of the installer 15 is connected w...

Embodiment 2

[0059] In this embodiment, a method for using the composite material temporary fastener verification device as in Embodiment 1 is proposed, including the following steps: image 3 As shown, at first, according to the composite material temporary fastener 16 to be tested, select the model of the air gun 6 that matches it, and install the air gun 6 between the first positioning part 5 and the first clamping part 7 to clamp Tighten air gun 6, composite material temporary fastener 16 is packed in the installer 15 simultaneously; Fasteners 16 , composite temporary fasteners 16 , are attached to composite panels 20 .

[0060] Then, after the composite material temporary fastener 16 is tightened on the composite material plate 20, the trigger of the air gun 6 is pulled to promote the composite material temporary fastener 16 to move in a direction close to the composite material plate 20, so that the composite material temporary The fastener 16 is installed in the composite material ...

Abstract

The invention discloses a composite material temporary fastener verification device and a use method thereof, and belongs to the technical field of mechanical assembly. The composite material temporary fastener verification device comprises: a bottom plate; an air gun which can slide on the bottom plate; a torque sensor which can slide on the bottom plate, wherein the torque sensor is connected with an output shaft of the air gun, and the torque sensor is used for detecting the torque of the output shaft of the air gun; an installer, wherein one end of the installer is connected with the torque sensor, the other end of the installer is provided with a composite material temporary fastener, and the air gun is used for driving the installer and the composite material temporary fastener to slide on the bottom plate so as to install the composite material temporary fastener into the composite material plate; a pressure sensor which is used for detecting the clamping force generated when the composite material temporary fastener is installed on the composite material plate, wherein the composite material temporary fastener, the installer, the torque sensor, the pressure sensor and the air gun are coaxial. The device has the advantage that the composite material temporary fastener can be accurately mounted.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a verification device for temporary fasteners made of composite materials and a method for using the same. Background technique [0002] In the assembly process of mechanical products, before the final assembly of the composite thin-walled structure, one or more rows of mounting holes need to be drilled on the composite thin-walled structure to facilitate the final assembly. Among them, in order to eliminate the gap between parts, avoid more burrs affecting the processing quality of the mounting holes, and avoid movement between parts during processing to affect the alignment of the mounting holes during final assembly, it is necessary to place the pre-processed positioning holes Insert the fasteners. However, in the assembly site, due to the limitation of the assembly space, only one-sided operation can be performed on the composite material thin-walled structure. A...
