[0022] As Figures 1-4 As shown in the figure, a steel bar punctuation machine for building steel engineering detection of the present invention includes a bottom plate 1. A clamping and fixing mechanism is arranged on the upper end surface of the bottom plate 1. A top plate 2 is horizontally arranged above the bottom plate 1. The corners of the top plate 2 are fixedly connected to the bottom plate 1 through vertically arranged support columns. A connecting plate 3 is horizontally installed on the upper end surface of the bottom plate 1 through a lifting control mechanism. The lifting control mechanism includes a second electric push rod 10 fixedly installed on the upper end surface of the top plate 2. The free end of the second electric push rod 10 movably penetrates the top plate 2. The free end of the second electric push rod 10 is fixedly connected to the upper end surface of the connecting plate 3. The second electric push rod 10 can drive the connecting plate 3 to move downward, indirectly driving the punctuation rod 5 to move downward for punctuation. A rotating roller 4 is horizontally rotatably installed on the lower end surface of the connecting plate 3. A plurality of punctuation rods 5 with different spacings are fixedly installed on the outer side wall of the rotating roller 4. The plurality of punctuation rods 5 are arranged at equal angular intervals. A tooth ring 6 is fixedly sleeved on the outer side wall of the rotating roller 4. A rack 7 is installed on the lower end surface of the connecting plate 3 through a sliding mechanism. The rack 7 is connected to a moving control mechanism. The rack 7 is meshed with the tooth ring 6. The third electric push rod 13 drives the rack 7 to move, and uses the movement of the rack 7 to drive the rotating roller 4 to rotate a fixed angle, realizing the replacement of punctuation rods 5 with different spacings. By setting the rotating roller 4 in this device and arranging a plurality of punctuation rods 5 with different spacings on the outer surface of the rotating roller 4 and controlling the rotating roller 4 to rotate a fixed angle, the replacement of different groups of punctuation rods 5 can be completed, and the functionality is stronger.

[0023] Specifically, the clamping and fixing mechanism includes two first electric push rods 8 horizontally and fixedly installed on the upper end surface of the bottom plate 1. The two first electric push rods 8 are symmetrically arranged. The free end of the first electric push rod 8 is fixedly installed with a fixing member 9.

The movement control mechanism includes a third electric push rod 13 horizontally and fixedly installed on the lower end surface of the connecting plate 3. The free end of the third electric push rod 13 is fixedly connected with the rack 7. The third electric push rod 13 drives the fixing member 9 to move, so that the two fixing members 9 cooperate to clamp and fix the steel bar. Moreover, the curved surface of the fixing member 9 is roughened, making the clamping of the fixing member 9 more stable and avoiding deflection when marking the steel bar.

[0024] More specifically, the sliding mechanism includes a chute 11 horizontally opened on the lower end surface of the connecting plate 3. A slider 12 is slidably installed on the inner side wall of the chute 11. The slider 12 is fixedly connected with the rack 7. The slider 12 and the chute 11 are provided to realize the connection between the rack 7 and the connecting plate 3, making the horizontal movement of the rack 7 more stable.

[0025] Working principle:

[0026] During use, place the steel bar horizontally between the two fixing members 9, and then control the first electric push rod 8 to extend, so that the two fixing members 9 move towards each other. The two fixing members 9 cooperate to clamp and fix the steel bar. Then control the third electric push rod 13 to extend to push the rack 6 to move. The rack 6 moves a fixed distance, causing the rotating roller 4 to rotate a fixed angle, making a group of marking rods 5 to be used vertically downward. Then control the second electric push rod 10 to extend to drive the connecting plate 3 to move downward. The marking rods 5 on the rotating roller 4 move downward synchronously with the connecting plate 3, and the marking rods 5 contact the steel bar for marking.
