Adjustable scale distance line marking device

Technical Field

The utility model belongs to the technical field of material tensile test equipment, and relates to an adjustable gauge length line marking device.

Background

Tensile test is an important performance index of the material, and many materials have requirements on the tensile test so as to ensure the strength and toughness of the material. The determination of elongation is an important part of the tensile test and represents an indication of the plastic deformation of the material, as well as the ability of the material to deform under static load. However, the original scale distance marking in the elongation measurement is always a tedious work of laboratory personnel, and has a large marking error, because the laboratory depends on a method of manually marking the scale distance by using a caliper, and therefore, an automatic scale distance marking device with high precision, convenience and rapidness in operation and good stability is urgently needed to replace manual marking.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

In fig. 1 to 3, the device comprises a base support 1, a sliding ruler 2, a sliding block 3, a marking pen 4, a first countersunk head bolt 5, a second countersunk head bolt 6, a sample placing platform 7, a screw 8 and the like.

As shown in fig. 1 to 3, the utility model relates to an adjustable scale distance line marking device, which comprises two base supports 1 arranged in parallel, a sliding ruler 2 is supported and arranged at the upper part between the two base supports 1, and two axial ends of the sliding ruler 2 are fixed and can rotate circumferentially.

Slide 2 and go up the slip rule and slide and set up two sliders 3, slider 3 slides on slip rule 2 to required position after, and is fixed through locating part, sets up the marker jack on slider 3, and marker 4 inserts in the marker jack, and the lower part of two base support 1 is connected through a kind placing platform 7, and the nib of marker 4 supports on a kind placing platform 7, and it can be understood, in order to ensure that marker 4 is fixed in position relative to slider 3, and marker 4 is fixed in on slider 3 through first countersunk head bolt 5. When the marking pen is used, the height of the marking pen 4 is adjusted, and the marking pen is screwed and fixed through the first countersunk head bolt 5.

As shown in fig. 1 and 2, cylindrical pins at two axial ends of the slide rule 2 are respectively inserted into corresponding mounting holes on the base bracket 1.

As shown in fig. 2, the positioning component includes a bolt hole disposed on the slider 3 and a second countersunk head bolt 6 in threaded fit connection with the bolt hole, and a bolt head of the second countersunk head bolt 6 abuts against the slide rule 2 to fix the position of the slider 3.

Before marking, the relative positions of the two sliding blocks 3 are adjusted, the position difference on the sliding ruler 2 is read, namely the relative positions of the two marking pens 4, after the relative positions of the sliding blocks 3 are determined, the second countersunk head bolt 6 is screwed and fixed, and after debugging is completed, marking operation can be achieved by rotating the sliding ruler 2.
