Description

TECHNICAL FIELD

[0001] The utility model belongs to wire performance detection technical field especially relates to a sample laser line's positioning device. BACKGROUND

[0002] The detection of the physical properties of deformed steel bars, particularly the elongation after fracture, maximum force total elongation and other data, requires high-precision laser marking or line marking to ensure the accuracy of the test results. During use of the detection equipment, due to the influence of the shape of the sample, the sample placement direction and the line marking direction are difficult to be perpendicular, which affects the accuracy of the detection and the work efficiency. SUMMARY

[0003] The utility model discloses a sample laser line's positioning device, solve the problem that the sample placement direction and the line marking direction are difficult to be perpendicular due to the influence of the shape of the sample.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A sample laser line's positioning device, including square tube, two relative settings square tube, one square tube top end along the length direction even set up a plurality of recess, the recess from top to down to the lateral wall middle part, the relative position of another square tube sets up recess from top to down to the lateral wall middle part.

[0006] Preferably, the cross section of the recess is trapezoidal, and the top side length of the recess is greater than the bottom side length.

[0007] Preferably, the length of the square tube is 250mm, the height is 20mm, and the top side length of the recess is 30mm.

[0008] The utility model discloses the beneficial effects achieved:

[0009] (1) through the recess of relative fixed sample, in the sample laser line process, it is convenient to make sample placement direction and line marking direction perpendicular, improve the accuracy of detection, and simultaneously, do not need manual intervention, improve the work efficiency of line marking process, both ends are set through square tube, and double positioning is realized at each end, improve the stability of sample positioning.

[0010] (2) the device structure is simple, convenient operation, and low in cost. DRAWINGS

[0014] Explanation of reference numerals in the attached drawings: 1. First square tube; 2. Second square tube; 3. First groove; 4. Second groove. Detailed Implementation

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1-2 As shown, a sample laser scribing positioning device includes a first square tube 1 and a second square tube 2, which are arranged opposite to each other. A plurality of first grooves 3 are evenly formed along the length of the top of the first square tube 1, extending downwards from the top to the middle of the side wall. A second groove 4 is formed in the second square tube 2, extending downwards from the top to the middle of the side wall.

[0017] The first groove 3 and the second groove 4 both have trapezoidal cross sections. The top side length of the first groove 3 and the second groove 4 is longer than the bottom side length. The length of the first square tube 1 and the second square tube 2 is 250 mm and the height is 20 mm. The top side length of the first groove 3 and the second groove 4 is 30 mm. By setting the first square tube and the second square tube, the two ends of the sample are double-limited, which improves the stability of sample fixation. The corresponding setting of the first groove and the second groove facilitates sample fixation and improves the accuracy of detection.

[0018] Usage process: such as Figure 3 As shown, during the laser scribing process, the first square tube 1 and the second square tube 2 of the positioning device are placed on both sides of the parallel scribing area, and the two ends of the sample are placed in the first groove 3 of the first square tube 1 and the second groove 4 of the second square tube 2, respectively, and the equipment can then start laser scribing.
