Description

Technical Field

[0001] The utility model relates to the technical field of workpiece lengthening measurement, in particular to an extended measuring ruler for a testing machine. Background Art

[0002] In materials testing machines, it's often necessary to measure the precise distance between the support plate and beam, or calibrate the parallelism between the beam and support plate, to ensure test accuracy and reliability. Traditional measurement methods may rely on manual use of common measuring tools such as tape measures or vernier calipers. These tools are not only cumbersome to operate but can also lead to measurement errors due to human error. Furthermore, because the distance between the support plate and beam of the testing machine can vary depending on the test requirements, traditional measurement tools often lack the flexibility to adapt to these changes.

[0003] In particular, in some high-precision or large testing machines, the distance between the support plate and the crossbeam may be large, exceeding the effective measurement range of ordinary measuring tools. This not only increases the difficulty of measurement, but may also affect the accuracy and safety of the test.

[0004] Therefore, in order to solve the above problems, an extended measuring ruler for a testing machine is proposed. Utility Model Content

The device can measure whether the crossbeam and the support plate of the testing machine are parallel and whether any parts are skewed, thereby improving the test accuracy of the testing machine. The device can meet a variety of usage scenarios and can adjust the length.

[0006] To achieve the above-mentioned purpose, the utility model provides an extended measuring ruler for a testing machine, comprising: a measuring rod, a measuring device and a top portion, wherein the measuring rod can adjust its length according to the distance between the support plate and the crossbeam of the testing machine, the measuring device is installed on the side surface of the upper part of the measuring rod, the bottom of the measuring rod is detachably connected to the top portion, the top of the measuring device contacts the lower surface of the crossbeam, and the lower end of the top portion is slidably connected to the upper surface of the support plate.

[0007] In the above method, the device is placed on the side of the column, and the height of the beam and the height of the measuring rod are adjusted so that the measuring rod can remain vertical after being placed. The data of the measuring device is observed, and the vertical differences of the measuring devices on the sides of each column are compared to determine whether the beam and the support plate remain parallel.

[0008] Furthermore, the measuring rod includes several plug-in rods, which are straight rod-shaped structures. Several of the plug-in rods are connected end to end to form a straight rod-shaped structure. The top part is detachably connected below the lowest plug-in rod, and the measuring device is installed on the topmost plug-in rod.

[0010] In the above manner, the plug-in rod is connected through the plugs and grooves at the head and tail, and the overall height is adjusted to adapt to different usage scenarios.

[0011] Furthermore, the measuring device includes a mounting base and a measuring dial indicator, the mounting base is arranged on the side of the upper part of the measuring rod, the measuring dial indicator is connected to the mounting base, and the measuring end of the measuring dial indicator faces upward and contacts the lower surface of the beam.

The minimum value is the vertical state. When the device moves, in order to improve the smoothness of the movement, the bottom of the top part is set to a magnetic steel ball, which can reduce friction.
