Description

Technical Field

[0001] The utility model relates to the technical field of steel bar detection, in particular to a gauge marking machine for steel bar detection. Background Art

[0002] A rebar gauge is an instrument used to calibrate the length of rebar before tensile testing. Also known as a gauge, dotting machine, or rebar dotting machine, rebar testing is particularly important in building material testing. Marking and distance measurement are paramount in rebar testing. Due to the rapid development of my country's construction industry, the workload in the materials testing industry is enormous. The accuracy of the dotting and the final measurement directly determine whether the rebar's tensile fracture index meets the standards. Most dotting machines place the rebar to be dotted in an arc-shaped slot and then perform the dotting. However, the dotting process generates a certain degree of vibration, and because pressure is applied to the rebar surface, the rebar may rotate, causing the dots to be off-line. This can cause inconvenience in subsequent test observations. Furthermore, adjusting the dotting spacing often requires adjusting and fixing the dotting columns one by one, making it inconvenient to use. Therefore, we propose a gauge dotting machine for rebar testing. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 6 A gauge marking machine for steel bar detection includes a base 1, a placement slot 2 for placing a sample is provided on the top of the base 1, and a marking base 4 is installed on the top of the base 1, and a marking column 5 for marking the sample is installed on the marking base 4, and the sample is hit from top to bottom by the marking column 5 to perform marking. A rotatable adjusting roller 12 is connected to the inside of the marking base 4 through an axle pin, and the adjusting roller 12 can be rotated at a fixed position in the marking base 4, and an equal-variable frame 13 is movably connected to the marking base 4, and the equal-variable frame 13 can be moved on a fixed track on the marking base 4, and a plurality of variable slots 17 that can adjust the equal-variable frame 13 at equal intervals are provided on the adjusting roller 12, and the equal-variable frame 13 is fixedly connected There is a movable column 19 movably connected in the variable groove 17. By rotating the adjusting roller 12, the movable column 19 can be in a relative movement in the variable groove 17, and then the movable column 19 can drive the variable frame 13 to move with equal amount and variable distance. When the variable frame 13 moves, the spacing between the variable frames 13 is always equal. The dotting column 5 is movably connected to the variable frame 13. Driven by the variable frame 13, the dotting column 5 can be transformed with equal distance. At the same time, two relatively movable clamping plates 9 are movably connected to the base 1. The clamping plate 9 can clamp the end of the sample. Under the limitation of the clamping plate 9, the sample can be dotted stably to avoid the sample from being offset during dotting, thereby ensuring the accuracy of dotting.

[0023] See also Figures 1 to 3A rotatable driving column 11 is movably mounted inside the base 1. The driving column 11 can rotate at a fixed position on the base 1. Two opposite threads are provided on the driving column 11. The clamping plates 9 are respectively connected to the two opposite threads. Driven by the opposite threads of the driving column 11, the clamping plates 9 can move relative to each other, and then the clamping plates 9 can move relative to each other to clamp the sample.

[0024] See also Figures 1 to 3 The placement groove 2 is V-shaped, so that when samples of different diameters are placed in the placement groove 2, the placement groove 2 can have a relatively limiting effect on the samples, thereby making it more versatile, and one end of the driving column 11 extends out of the interior of the base 1 and is fixedly connected to the rotating disk 10. The driving column 11 is operated by the rotating disk 10, making its operation more convenient.

[0025] See also Figures 1 to 6 The top of the dotting column 5 passes through the constant-variable frame 13 and is fixedly connected to the rising plate 16. Driven by the rising plate 16, the dotting column 5 can move relative to the constant-variable frame 13. At the same time, the top of the dotting column 5 is sleeved with a second spring 18. The top of the second spring 18 is fixed to the bottom of the rising plate 16, and the bottom end of the second spring 18 is fixed to the constant-variable frame 13. Under the action of the pulling force of the second spring 18, the rising plate 16 pulls up the dotting column 5, and the dotting column 5 can return to its position, and then hit the sample, thereby achieving the dotting effect.

[0026] See also Figures 1 to 6 The inside of the dotting base 4 is connected to a rotating rod 14 through an axle pin. The rotating rod 14 can rotate at a fixed position in the dotting base 4, and the outside of the rotating rod 14 is fixedly connected to a spiral pushing plate 15 that can contact the bottom of the rising plate 16. Then, driven by the rotating rod 14, the pushing plate 15 can rotate, and then push the rising plates 16 up one by one. The other dotting columns 5 can still contact the sample to limit the sample.

[0027] See also Figures 1 to 6 A first motor 7 and a second motor 8 are fixedly installed on the outer side of the dotting base 4. The output shaft of the first motor 7 is connected to one end of the adjusting roller 12. Driven by the output shaft of the first motor 7, the adjusting roller 12 can rotate. The first motor 7 is a prior art and will not be described in detail here. The output shaft of the second motor 8 is connected to one end of the rotating rod 14. Driven by the output shaft of the second motor 8, the rotating rod 14 can rotate. The second motor 8 is a prior art and will not be described in detail here.

[0028] See also Figures 1 to 3A plurality of limiting columns 3 are fixedly connected to the top of the base 1, and the limiting columns 3 are movably connected to the dotting base 4, so that the dotting base 4 can move along a fixed trajectory, and then smoothly drive the dotting columns 5 to contact the sample. A first spring 6 is sleeved on the limiting column 3, and the top of the first spring 6 is fixed to the bottom of the dotting base 4, and the bottom end of the first spring 6 is fixed to the top of the base 1. Under the action of the elastic force of the first spring 6, the dotting base 4 can be returned to its position, so that the sample can be placed smoothly.

[0029] In summary, when the gauge marking machine for steel bar inspection is used, the sample is placed in the placement slot 2 and the rotating disk 10 is rotated. Driven by the rotating disk 10, the driving column 11 is rotated. Then the two clamping plates 9 can move relative to each other, and the sample can be clamped in the middle of the placement groove 2, and then the dotting base 4 is pressed down, so that the dotting column 5 can contact the sample, and then driven by the output shaft of the second motor 8, the rotating rod 14 can rotate, and then drive the pushing plate 15 to rotate. Under the action of the rotation of the pushing plate 15, the rising plate 16 can be pushed upward in turn, and under the continued rotation of the pushing plate 15, the rising plate 16 is separated from the contact with the pushing plate 15. At this time, under the action of the tension of the second spring 18, the rising plate 16 can drive the dotting column 5 to strike the surface of the sample downward in a different place, so as to realize the sequential marking of the sample. When adjusting the dotting spacing, driven by the output shaft of the first motor 7, the adjusting roller 12 can be moved, and then the moving column 19 can be in the variable groove 17 for relative movement, driving the variable frame 13 to move, thereby realizing equal distance variation between the dotting columns 5.
