[0030] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 , Figure 3 and Figure 4 As shown, both the measuring stationary clamp 3 and the measuring movable clamp 6 have an "h"-shaped structure, with the lower end face of the measuring movable clamp 6 being higher than the lower end face of the measuring stationary clamp 3. A screw hole 15 is provided at the lower left end of the measuring movable clamp 6. A scale plate 4 is integrally connected to the lower right side wall of the measuring stationary clamp 3, and the scale plate 4 is in contact with a measuring pointer 16 fixed to the left side wall of the right end of the measuring movable clamp 6. A measuring gauge 17 is installed and connected to the right side wall of the measuring movable clamp 6. A lead screw 18 is threaded into the screw hole 15, and the lead screw 18 is rotatably connected to the front and rear end faces of the support base 1. The front end of the lead screw 18 is fixedly connected to the output end of the bidirectional motor 2. When the reinforcing bar is placed on the upper surface of the measuring clamping plate 3, the power switch of the bidirectional motor 2 is turned on. The bidirectional motor 2 drives the lead screw 18 to rotate. The lead screw 18 is threadedly connected to the lower end of the measuring moving clamping plate 6, which facilitates the sliding of the measuring moving clamping plate 6 on the slide groove 5. This allows the measuring moving clamping plate 6 and the measuring clamping plate 3 to clamp the reinforcing bar. The measuring pointer 16 fixed on the right end of the measuring moving clamping plate 6 points to the scale line on the scale plate 4. The measuring instrument 17 identifies and displays the scale line, which facilitates quick and accurate measurement of the diameter of the reinforcing bar. The measuring clamping plates 3 are set at equal intervals on the support base 1 to measure various positions of the reinforcing bar, thereby obtaining more detailed data on the reinforcing bar.

[0031] Combination Figure 1 and Figure 2As shown, the fixed cleaning housing 7 is fixedly connected to the lower inner surface of the support base 1, and a moving cleaning housing 9 is provided at the front end of the fixed cleaning housing 7. A sliding rod 8 is connected through the lower left side of the moving cleaning housing 9, and a threaded rod 10 is threadedly connected to the lower right side of the moving cleaning housing 9. The moving cleaning housing 9 forms a sliding structure on the sliding rod 8 through the threaded rod 10. The upper end of the moving cleaning housing 9 and the upper end of the fixed cleaning housing 7 form a cylindrical structure. Cleaning soft brushes 11 are attached to the inner walls of the upper ends of both the moving cleaning housing 9 and the fixed cleaning housing 7. A slot 12 is provided at the rear end of the moving cleaning housing 9, and a locking block 13 is engaged inside the slot 12. The locking block 13 engages with the cleaning... A support block 14 is vertically fixed to the upper end face of the contact end of the fixed shell 7. The upper end face of the support block 14 has an arc structure and is flush with the outer end face of the cleaning soft brush 11. The threaded rod 10 is rotated and is threadedly connected to the lower end of the moving shell 9, which facilitates the adjustment of the distance between the moving shell 9 and the fixed shell 7. The support block 14 lifts the steel bar, which makes it easier for the cleaning soft brush 11 to contact the outer surface of the steel bar better. When the steel bar is dragged to the left, the cleaning soft brush 11 cleans the outer surface of the steel bar, which facilitates more accurate measurement of the steel bar diameter. This is the working process of the steel bar diameter detection device.
