Embodiment Construction

[0011] figure 1 Shown is a strain gauge push-extrusion patching device and its use method, which consists of an upper and lower platform 1, an upper and lower sliding rod 2, an upper and lower connecting rod 3, a slider 4, and a screw 5.

[0012] The upper and lower platforms 1 are glued to the upper and lower sliding rods 2, and the surface is flat and smooth, and the relative movement of the two platforms can be realized as the upper and lower sliding rods move up and down; the upper and lower connecting rods 3 are riveted to the upper and lower sliding rods 2 by rivets 9 and 10 respectively. And on the slider 4, used to transmit the movement between the upper and lower rods 2 and the slider 4; the slider 4 is welded on the left end of the screw 5, and can move with the movement of the screw; the right end of the screw 5 is provided with Hexagon nut, the middle end engages with the screw hole 8.

[0013] Combine below figure 1 The course of work of the present invention is...

Abstract

The invention belongs to the technical field of sensing detection, and particularly relates to a device for propelling and extruding patching of a strain sheet and an using method thereof. The devicecomprises an upper platform, a lower platform, an upper sliding rod, a lower sliding rod, an upper connecting rod, a lower connecting rod, a sliding block and a screw. The device has the beneficial effects of being simple in structure, low in cost, good in the patch quality, and efficient in completion of the patching of the strain sheet. According to the method, the strain sheet is adhered to thesurface of tested objects through glue, and then the two tested objects are symmetrically clamped through a clamp, the strain sheet patching auxiliary device is arranged between two tested objects, the screw is rotated, the upper platform and the lower platform are gradually separated along with screwing of the screw, the upper platform and the lower platform are enabled to abut against the strain sheet and are gradually compressed, and finally a certain pressure is kept to carry out curing and stabilizing treatment on the strain sheet.

Description

technical field [0001] The invention belongs to the technical field of sensing and detection, and in particular relates to a strain gauge pushing extrusion patching device and a use method thereof. Background technique [0002] The working principle of the strain gauge is based on the strain effect, and its paste quality directly affects the accuracy of the strain gauge measurement. The traditional method of attaching strain gauges is manual operation. A layer of polytetrafluoroethylene film is attached to the surface of the strain gauge, and the excess glue is applied along the axial direction of the strain gauge by hand and the air bubbles in the glue layer are discharged. , and then cover the temperature-resistant silicone rubber plate on the polytetrafluoroethylene film, and apply a certain pressure for curing and stabilization. Manual patching is not only uneven, but also not easy to get rid of air bubbles and impurities in the adhesive layer, which cannot guarantee th...
