[0025] In order to make the limit frame have a mechanism that can easily adjust the position of the limit structure, it is convenient to limit the steel bars of different diameters when straightening according to needs, such as Figure 1-6 As shown, a steel bar limiting frame of a steel bar straightening machine described in the utility model comprises a base 1, a first guide rail 2, a vertical plate 3, a second guide rail 6, a first rotating disk 21 and a second rotating disk 23;

[0026] A vertical plate 3 and a first guide rail 2 are respectively provided at two ends of the top of the base 1, a servo motor 4 is provided at the inner side of the vertical plate 3 near the bottom through a fixed seat, a screw rod 5 is connected to the power output end of the servo motor 4, a screw block 9 is sleeved on the outer side of the screw rod 5, a slider 10 is sleeved in the first guide rail 2, a rod body 11 is connected between the screw block 9 and the slider 10, a sleeve block 12 is sleeved on the outer side of the rod body 11, a rectangular plate 13 is connected to the bottom of the sleeve block 12, a stopper 14 is connected to the bottom of the rectangular plate 13, an extension block 15 is provided on one side of the stopper 14, a distance detection sensor 16 is fixed to the bottom of the extension block 15 by screws, a hollow shaft 22 is connected to the inner side of the first rotating disk 21, a second rotating disk 23 is sleeved on the outer side of the end of the hollow shaft 22, a connecting disk 26 is connected to the end of the hollow shaft 22 by a third bolt 28, the connecting disk 26 and the second rotating disk 23 are fastened by a second bolt 27, and a second rotating shaft 29 is connected to the outer side of the connecting disk 26.

[0027] When in use, a limiting structure is formed by the first rotating disk 21, the hollow shaft 22 and the second rotating disk 23. The width between the inclined guide surfaces 30 is gradually reduced from the outside to the inside through the inclined guide surface 30 on the inner side of the first rotating disk 21. The servo motor 4 can easily drive the screw rod 5 to rotate when working, so that the wire block 9 can move up and down along the second guide rail 6, and then can drive the rod body 11, the sleeve block 12, the rectangular plate 13 and the stopper 14 to move up and down. The stopper 14 that can move up and down cooperates with the first rotating disk 21 and the second rotating disk 23, so that the limiting frame has a mechanism for adjusting the position of the limiting structure, which is convenient for limiting the steel bars of different diameters when straightening according to needs.

[0028] For example, Figure 1 and Figure 6 As shown, the utility model also includes that the top of the base 1 is connected to a connecting block 24 near both ends of the center through a first bolt 25, the inner side of the connecting block 24 is connected to a support plate 17, the top of the support plate 17 is connected to a fixing block 18, and one end of the fixing block 18 is provided with a bearing 19 through a mounting groove.

[0029] When in use, the connecting block 24 is conveniently locked and fixed by the first bolt 25 , and the bearing 19 is conveniently installed by the fixing block 18 .

[0030] For example, Figure 1 and Figure 6 As shown, the utility model also includes that the first rotating disk 21 is connected to the first rotating shaft 20 near the center at one end away from the hollow shaft 22 , and the first rotating shaft 20 and the second rotating shaft 29 are both sleeved in corresponding bearings 19 .

[0031] When in use, the bearing 19 provides a limiting and guiding function for the first rotating shaft 20 and the second rotating shaft 29 , thereby effectively improving the stability of the first rotating disk 21 and the second rotating disk 23 during rotation.

[0032] For example, Figure 1 As shown, the utility model also includes that the inner walls of the first rotating disk 21 and the second rotating disk 23 are both provided with inclined guide surfaces 30 .

[0033] When in use, the inclined guide surface 30 can provide spaces of different widths inside the first rotating disk 21 and the second rotating disk 23, so that steel bars of different diameters can pass between the first rotating disk 21 and the second rotating disk 23 after adjusting their own heights.

[0035] When in use, the wire block 9 is limited by the second guide rail 6 so that when the screw rod 5 rotates, it can only drive the wire block 9 to move up and down along the second guide rail 6.

[0036] When the utility model is in use, a limiting structure is formed by the first rotating disk 21, the hollow shaft 22 and the second rotating disk 23. The width between the inclined guide surfaces 30 is gradually reduced from the outside to the inside through the inclined guide surface 30 on the inner side of the first rotating disk 21. When the height of the external steel bar to be straightened is adjusted up and down, the steel bars of different diameters can be limited by moving between the inclined guide surfaces 30. The servo motor 4 can conveniently drive the screw rod 5 to rotate during operation, so that the wire block 9 can move up and down along the second guide rail 6, and then can drive the rod body 11, the sleeve block 12, the rectangular plate 13 and the stopper 14 to move up and down. The stopper 14 that can move up and down cooperates with the first rotating disk 21 and the second rotating disk 23, so that the limiting frame has a mechanism for adjusting the position of the limiting structure, so that the steel bars of different diameters can be limited according to needs when straightening.
