Abstract
The utility model discloses a test bar auxiliary measuring clamp, which comprises a positioning seat (1) and a screw (3), and is characterized in that; the front end and the rear end of the positioning seat (1) are respectively screwed with a screw (3), a groove (2) is arranged on the positioning seat (1), and a positioning hole (4) is arranged on the side surface. The utility model discloses guarantee that the test bar is rule accurate unanimous, the test bar is concatenation and measurement convenience after tensile, and single can operate and ensure that ultimate calculation data is accurate reliable.
Description
Technical Field
The utility model belongs to the technical field of anchor clamps, a test bar auxiliary measurement anchor clamps is related to particularly.
Background
At present, a company uses a large amount of metal 3D printing equipment to produce parts, and circular test bars are required to be made in each batch to verify the physical properties of the parts so as to ensure the quality of the parts. When the elongation percentage after fracture is measured by a stretching test of a circular test bar, the test bar is scribed according to the gauge length before stretching, the broken test bars are spliced together after stretching to measure the distance between the scribed lines, and then the elongation percentage after fracture is obtained through calculation. When the line is drawn according to the gauge length, the calculation result is influenced due to large line drawing error caused by manual operation; need two people cooperation operation when will test bar concatenation after the drawing, the test bar of alone fixed concatenation, alone measurement, the operation is inconvenient.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned shortcoming and provide a guarantee that the test bar rule is accurate unanimous, and the test bar is spliced after tensile and is measured conveniently, and single can operate and ensure the accurate reliable test bar auxiliary measurement anchor clamps of ultimate calculation data.
The purpose of the utility model and solve its main technical problem and adopt following technical scheme to realize:
the utility model discloses a test bar auxiliary measuring clamp, which comprises a positioning seat and a screw and is characterized in that; screws are respectively screwed in the front end and the rear end of the positioning seat, a groove is formed in the positioning seat, and a positioning hole is formed in the side face of the positioning seat.
The groove is cross-shaped.
And two positioning holes are formed and communicated with the groove.
Compared with the prior art, the utility model, have obvious beneficial effect, can know from above technical scheme: screws are respectively screwed into the front end and the rear end of the positioning seat, a groove is formed in the positioning seat, and a positioning hole is formed in the side face of the positioning seat. The round test bar is placed in the groove, the two marking pens are respectively inserted into the positioning holes, the pen points of the marking pens penetrate out to be in contact with the round test bar, the distance between the two positioning holes is the scale distance of the round test bar, the screws are respectively screwed in to enable the screws to be respectively in contact with the two end faces of the round test bar, the round test bar cannot transversely move by adjusting the positions of the screws, the round test bar is rotated in the cross-shaped groove, the two marking pens respectively draw a next circle of line with fixed scale distance on the round test bar, and the marked lines are consistent in scale distance, stable and reliable. After the circular test rods are subjected to tensile fracture, the circular test rods subjected to tensile fracture are respectively placed in the grooves of the positioning seats, the circular test rods subjected to fracture are clamped through the adjusting screws respectively, and the distance between the marking lines is measured after the circular test rods are clamped, so that the method is simple, convenient and easy to operate, simple to operate and accurate in data. In a word, the utility model discloses guarantee that the test bar rule is accurate unanimous, the test bar is spliced and is measured the convenience after tensile, and single can operate and ensure that ultimate calculation data is accurate reliable.
