[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figure 1 - Figure 4 shown, the present invention provides a steel bar limiting mechanism for a steel bar cutting machine, including a fixed table 1. Vertical grooves 11 are respectively formed through the upper end of the fixed table 1 near the four corners. A limiting mechanism 2 is arranged on the upper end of the fixed table 1, and a length adjustment mechanism 3 is arranged on the upper end of the fixed table 1;

[0024] The limiting mechanism 2 includes a special-shaped seat 21. First cylinders 22 are respectively arranged inside the four groups of vertical grooves 11. Two limit seats 23 are fixedly installed on the upper end of the fixed table 1. A bottom plate 24 is arranged below the fixed table 1. V-shaped grooves 25 are respectively formed at one ends of the two limit seats 23. The extending ends of the four groups of first cylinders 22 are respectively fixedly installed with top plates 26. Limit grooves 27 are respectively formed at the upper ends of the two limit seats 23. Triangular plates 28 are respectively fixedly installed at one ends of the four groups of top plates 26. Pressing blocks 29 are respectively slidably installed inside the two limit grooves 27. The other ends of the four groups of triangular plates 28 are respectively fixed to the two ends of the two pressing blocks 29. Two guide rails 210 are respectively fixedly installed on the inner side walls of the four groups of special-shaped seats 21. Slide blocks 211 are slidably installed on the outer walls of the eight guide rails 210. The lower ends of the four groups of first cylinders 22 are respectively fixed to the inner bottom ends of the four groups of special-shaped seats 21. One ends of the eight slide blocks 211 are respectively fixed to one sides of the four groups of top plates 26. The lower ends of the four groups of special-shaped seats 21 are respectively fixed to the upper end of the bottom plate 24. A diagonal support plate 12 is fixedly installed on one side of the bottom plate 24. The upper end of the diagonal support plate 12 is fixed to the lower end of the fixed table 1.

[0025] Specifically describe the specific settings and functions of this embodiment below. By synchronously starting the first cylinder 22, the extending ends of the four groups of first cylinders 22 drive the four groups of top plates 26 to move downward. The four groups of top plates 26 drive the two pressing blocks 29 to move downward together through the four groups of triangular plates 28, so that the two pressing blocks 29 slide downward inside the two limiting grooves 27 respectively until the lower ends of the two pressing blocks 29 contact the outer wall of the steel bar. Coupled with the special design of the V-shaped grooves 25, the steel bar can be fixed inside the two V-shaped grooves 25, thus eliminating the need to frequently adjust the clamping position and clamping force of the limiting mechanism, saving time and effort, and not taking a long time to adjust to the appropriate state, improving the cutting and processing efficiency of the steel bar;

[0026] When the four groups of top plates 26 move up and down, the four groups of top plates 26 respectively drive the two sliding seats 211 on one side, so that the eight sliding seats 211 slide on the outer walls of the eight guide rails 210 respectively, which can guide and stabilize the movement of the four groups of top plates 26, thereby increasing the stability of the four groups of top plates 26 when moving;

[0027] The setting of the diagonal support plate 12 can support the fixed table 1 and increase the stability of the fixed table 1.

[0028] Embodiment Two: As Figure 1 and Figure 4 shown, the length adjustment mechanism 3 includes a fixed plate 31. A push plate 33 is arranged at the upper end of the fixed table 1. A long hole 34 is penetrated and opened at the upper end of the fixed table 1. A sliding block 32 is slidably installed inside the long hole 34. One end of the fixed plate 31 is penetrated and installed with a second cylinder 35. The lower end of the fixed plate 31 is fixed to the upper end of the fixed table 1. The upper end of the sliding block 32 is fixed to the lower end of the push plate 33. The extending end of the second cylinder 35 is fixed to one end of the push plate 33.

[0029] The overall effect achieved by this embodiment is that when the second cylinder 35 is started, the extending end of the second cylinder 35 pushes the push plate 33 to move on the upper end of the fixed table 1. The push plate 33 drives the sliding block 32 to slide inside the long hole 34, increasing the stability of the push plate 33 when moving, and can drive the push plate 33 to extend or contract, so as to adjust the distance between the push plate 33 and one of the limiting seats 23, thereby being able to block the length of the steel bar according to requirements and facilitating cutting the required length of the steel bar.

[0030] Usage method and working principle of the device: First, according to the length of the required steel bar, adjust the length adjustment mechanism 3 first. Start the second cylinder 35. The extending end of the second cylinder 35 pushes the push plate 33 to move on the upper end of the fixed table 1. The push plate 33 drives the sliding block 32 to slide inside the long hole 34, increasing the stability when the push plate 33 moves, and can drive the push plate 33 to extend or contract, thereby adjusting the distance between the push plate 33 and one group of limit seats 23. Finally, insert the steel bar into the inside of the two V-shaped grooves 25, and then start the first cylinder 22 synchronously. The extending ends of the four first cylinders 22 drive the four top plates 26 to move downward. The four top plates 26 drive the two pressing blocks 29 to move downward together through the four triangular plates 28, so that the two pressing blocks 29 slide downward inside the two limit grooves 27 respectively until the lower ends of the two pressing blocks 29 contact the outer wall of the steel bar. Coupled with the special design of the V-shaped grooves 25, the steel bar can be fixed inside the two V-shaped grooves 25 and can be fixed inside the two limit seats 23, facilitating subsequent cutting of the steel bar.

[0031] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
