Embodiment Construction

[0011] like figure 1 and 2 As shown, a test device for the strength and deformation of thin-walled parts has a structure as follows: two clamping plates 6 are arranged symmetrically on the upper surface of the base 3, and each clamping plate 6 is fixedly connected to the base 3 through a gusset 10. , there are several guide posts I8 threaded on one clamping plate 6, and guide posts II11 corresponding to the number and position of guide posts I8 are provided on the other clamping plate 6, and compression A spring 7; a stopper 5 is arranged outside the cardboard 6 provided with the guide post II11, and the stopper 5 is movably connected with the base 3; several movable positioning blocks 2 are arranged between the two stoppers 5.

[0012] The bottom of the base 3 is provided with a U-shaped support 4 .

[0013] The outer end side of the guide post I8 is provided with a pin 9 .

[0014] When working, first place the tested part 1 between the guide post II11 and the positioning...

Abstract

The invention relates to a device for testing strength and distortion of a thin-wall part. In the device, two clamping boards are arranged on the surface of a pedestal symmetrically; each clamping board is fixedly connected with the pedestal through an angle brace; one clamping board is threadedly connected with a plurality of guide pillars I; the other clamping board is provided with guide pillars II with the quantity and the position corresponding to those of the guide pillars I; compression springs are arranged among the guide pillars I and the guide pillars II; stop dogs are arranged on the outer side of the clamping board provided with the guide pillars II and are moveably connected with the pedestal; a plurality of moveable positioning blocks are arranged between the two stop dogs; and a U-shaped support is arranged below the pedestal. The device has a compact structure, is easy to operate, can measure finished product parts directly, and greatly improves working efficiency.

Description

technical field [0001] The invention relates to a testing device for the strength and deformation of thin-walled parts, which is used for measuring the strength and deformation of thin-walled parts. Background technique [0002] At present, in the aerospace manufacturing industry, in order to reduce weight and improve the structural strength and performance of aircraft and spacecraft, thin-walled structural parts are used as much as possible, such as thin-walled frames, wall panels, and wing ribs in aircraft structural parts. and engine turbine blades, etc. In addition, it also includes hollow structural components formed by applying superplastic forming technology, which are increasingly widely used in industrial fields such as aircraft, engines, and missiles. These parts are load-bearing structural parts, therefore, their shaped products must pass through multiple load and deformation tests before they can be used. However, the existing measuring equipment can only be te...
