Embodiment Construction

[0011] figure 1 Shown is a spiral extrusion attachment device for strain gauge patches, which consists of an upper plate 1, a lower plate 2, a platform 3, a threaded push rod 4, and a support rod 5.

[0012] The upper plate 1 and the lower plate 2 are interlacedly connected by two support rods 5, and as the angle between the two support rods 5 is changed, the relative movement of the upper plate 1 and the lower plate 2 can be realized; the platform 3 is set as a trapezoid, respectively Welded on the outer surfaces of the upper plate 1 and the lower plate 2, the surface is flat and smooth, and is used to compress the strain gauge 13; the threaded push rod 6 includes a hexagonal rod 7 and a threaded cone 8; the hexagonal rod 7 is a hexagonal prism, It is convenient to clamp the wrench; the threaded cone 6 and the hexagonal rod 7 are welded together, and the surface of the threaded cone 6 is provided with an external thread 8; the support rod 5 is two, the middle is connected by ...

Abstract

The invention belongs to the technical field of sensor detection, and particularly relates to a screw-extrusion attaching device for strain gauge patching. The device comprises an upper plate, a lowerplate, a platform, threaded push rods and support rods. The strain gauge is glued to the surface of the object to be tested, then two objects to be tested are symmetrically clamped by a clamp, and the attaching device is placed between the two objects. The threaded push rods are rotated, a threaded taper gradually pushes inward under the meshing of internal and external threads, the two support rods are extended at an angle, and the upper and lower plates gradually move away, so that the raised platform abuts against and gradually presses the strain gauge. Finally, a certain pressure is maintained so as to solidify and stabilize the strain gauge. The device can make the strain gauge stick more uniformly, and can eliminate air bubbles in the glue, so that the measurement precision of the strain gauge is higher.

Description

technical field [0001] The invention belongs to the technical field of sensing and detection, and in particular relates to a spiral extrusion attachment device for strain gauge patches. Background technique [0002] The working principle of the strain gauge is based on the strain effect, and its pasting quality directly affects the measurement accuracy of the strain gauge. 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 placement is not only uneven, but also not easy to get rid of air bubbles and impurities in the adhesive layer, which cannot guarantee the accurac...
