Problems solved by technology

For most of the testing machines, the machine is not equipped with precise positioning devices. During the operation, visual positioning or manual measurement is often used to position the specimen. The positioning is inaccurate, resulting in large errors in later experiments. At the same time, the positioning operation It is also inconvenient to adjust, it is difficult to apply to specimens of various sizes and shapes, and it is even more difficult to achieve efficient positioning at any point within the range of the specimen loading working surface

Embodiment 1

[0032] Such as Figure 1~4 As shown, a multi-scale test piece coordinate positioning device includes a positioning component; the positioning component includes a scale frame, a slider, a telescopic tube, and an inline laser. The scale frame has scales, and the slider slides with the scale frame The sliding direction of the slider is parallel to the extension direction of the scale. One end of the telescopic tube is hinged to the slider through the first hinge point, and the other end of the telescopic tube is hinged to the line laser through the second hinge point. Both the axis and the axis of the second hinge point are parallel to the sliding direction of the slider.

[0033] The positioning component also includes a magnetic base, which is fixedly connected with the scale frame.

[0034] The scale frame is a telescopic structure, and the scale frame includes a ruler cover, and the number of the ruler cover is multiple, and the multiple ruler covers are sequentially socket...

Embodiment 2

[0055] In this embodiment, in step S4, the eccentricity required for the test is 50 mm. In step S4, first move the slider until the intersection point of the laser lines coincides with the origin so as to obtain the position of the origin through the scale passed by the laser lines, and then move the A slider moves 50mm on the scale frame. At this time, the distance between the intersection point of the two laser lines and the origin is 50mm, that is, the intersection point reaches the target position.

[0056] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

Abstract

The multi-scale test piece coordinate type positioning device comprises a positioning assembly. The positioning assembly comprises a graduated scale frame, a sliding block, a telescopic pipe and a linear laser, the graduated scale frame is provided with scales, the sliding block is slidably connected with the graduated scale frame, the sliding direction of the sliding block is parallel to the extending direction of the scales, one end of the telescopic pipe is hinged to the sliding block through a first hinge point, and the other end of the telescopic pipe is hinged to the linear laser through a second hinge point; the axis of the first hinge point and the axis of the second hinge point are both parallel to the sliding direction of the sliding block. The invention further relates to a multi-scale test piece coordinate type positioning method. The multi-scale test piece coordinate type positioning device is adopted, and the test piece is positioned through the laser rays emitted by the linear laser device; the high-precision positioning function of any point of a working plane is efficiently achieved, and the multi-scale test piece coordinate type positioning device is wide in applicability, easy to operate, wide in used material, low in cost and detachable; the device is convenient to move and carry. The invention belongs to the technical field of building structures.

Description

technical field [0001] The invention relates to the field of building structure testing, in particular to a multi-scale test piece coordinate positioning device and a positioning method. Background technique [0002] In recent years, with the innovation and development of building materials and components, building structures have continuously achieved high performance. However, before the new building technology is popularized and applied in actual projects, a large number of material and structural component tests need to be carried out. According to different specimen sizes, test objectives and requirements, different test equipment is used in the experiment to carry out tests in different working conditions such as tension, compression, bending, shearing and torsion. For most of the testing machines, the machine is not equipped with precise positioning devices. During the operation, visual positioning or manual measurement is often used to position the specimen. The posi...
