Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment

[0019] As Figures 1 to 3 shown, a steel bar limiting device for a dotting machine includes: a base 1, a dotting machine main body 2 is provided at the center of the top of the base 1, auxiliary positioning frames 3 are provided on both the front and rear sides of the dotting machine main body 2 on the top of the base 1, and clamping seats 4 are provided on both the front and rear sides of the auxiliary positioning frames 3 on the top of the base 1;

[0020] Place the base 1 at a designated position, then place the steel bar to be dotted between the two clamping seats 4, and clamp and fix the front and rear sides of the steel bar through the two clamping seats 4 to prevent the steel bar from moving during dotting, which affects the dotting efficiency. At the same time, the steel bar is assisted in positioning through the auxiliary positioning frame 3, improving the limiting effect, and thus facilitating the dotting machine main body 2 to perform dotting processing on the steel bar.

[0021] Auxiliary positioning frames 3 are provided on both the front and rear sides of the dotting machine main body 2 on the top of the base 1; the auxiliary positioning frames 3 are used to assist in positioning the steel bar, and the specific structure of the auxiliary positioning frames 3 is as follows:

[0022] Reinforcing frames 301 are fixedly connected to both the left and right sides of the auxiliary positioning frames 3 on the top of the base 1. A lifting cylinder 302 is provided at a position corresponding to the auxiliary positioning frame 3 on the top of the base 1. A connecting seat 303 is fixedly connected to the top of the lifting cylinder 302. A clamping frame 304 is connected to the inside of the connecting seat 303 through a connecting shaft. The clamping frame 304 is connected to the auxiliary positioning frame 3 through a rotating plate 305. The rotating plate 305 is rotatably connected to the auxiliary positioning frame 3 through a connecting shaft. A buffer seat 306 is provided at a position corresponding to the auxiliary positioning frame 3 at the bottom of the clamping frame 304, and a buffer spring 307 is provided at a position corresponding to the buffer seat 306 inside the auxiliary positioning frame 3.

[0023] The steel bar is clamped and fixed by the auxiliary positioning frame 3. The steel bar is placed on the top of the two groups of auxiliary positioning frames 3. Subsequently, the lifting cylinder 302 drives the connecting seat 303 to move, and then the connecting seat 303 drives the clamping frame 304 to move. The clamping frame 304 rotates with the connecting seat 303 through the connecting shaft. At the same time, when the clamping frame 304 rises, it rotates with the auxiliary positioning frame 3 through the rotating plate 305. During use, the buffer spring 307 in the buffer seat 306 plays a buffering role for the clamping frame 304.

[0024] Clamping seats 4 are provided on the top of the base 1 and on the front and rear sides of the auxiliary positioning frame 3; the clamping seats 4 are used to firmly clamp the steel bar. The specific structure of the clamping seat 4 is as follows:

[0025] Clamping grooves 5 are opened on the inner sides of the two groups of clamping seats 4, and clamping components 6 are provided inside the clamping seats 4 at positions corresponding to the clamping grooves 5.

[0026] The clamping component 6 includes two groups of knobs 601, connecting columns 602, clamping blocks 603, limiting blocks 604, limiting rings 605 and stabilizing columns 606. The two groups of knobs 601 are respectively arranged on the front and rear sides of the clamping seat 4. The two groups of knobs 601 are both connected with clamping blocks 603 through connecting columns 602. Limiting blocks 604 are fixedly connected to the left and right sides of the two groups of clamping blocks 603 inside the clamping groove 5. A number of limiting rings 605 are opened inside the clamping blocks 603 and the limiting blocks 604. The connection methods of the two groups of connecting columns 602 with the clamping seat 4 are respectively threaded connections. One side of the connecting column 602 penetrates through the clamping seat 4 and is rotatably connected with the clamping block 603. The other side of the connecting column 602 penetrates through the clamping seat 4 and is fixedly connected with the knob 601. Stabilizing columns 606 are provided on the front and rear sides of the clamping seat 4 and on the upper and lower sides of the two groups of knobs 601.

[0027] Through the clamping component 6, rotate the first knob 601. One side of the first connecting column 602 penetrates through the clamping seat 4 and is rotatably connected with the first clamping block 603. The other side of the first connecting column 602 penetrates through the clamping seat 4 and is fixedly connected with the first knob 601. The first knob 601 drives the first connecting column 602 to rotate. When the first connecting column 602 rotates, it drives the first clamping block 603 to move. The two groups of stabilizing columns 606 both penetrate through the clamping seat 4 and are fixedly connected with the first clamping block 603. The connection methods of the two groups of stabilizing columns 606 with the clamping seat 4 are both sliding connections. When the first clamping block 603 moves, it drives the two groups of stabilizing columns 606 to move. The stabilizing columns 606 can prevent the first clamping block 603 from shifting when moving. The steel bar is clamped by the two groups of first clamping blocks 603 and the two groups of first limiting blocks 604. The clamping process is easy and fast, which is convenient for the user to clamp. When clamping, the limiting rings 605 on the inner sides of the first limiting block 604 and the first clamping block 603 are engaged with the iron rings on the surface of the steel bar.

[0028] Embodiment: First, place the base 1 at the designated position, then place the steel bar to be marked between the two groups of clamping seats 4. Clamp and fix the front and rear sides of the steel bar through the two groups of clamping seats 4 to prevent movement during the marking of the steel bar, which may affect the marking efficiency. At the same time, use the auxiliary positioning frame 3 to assist in positioning the steel bar, improving the limiting effect, and thus facilitating the marking machine main body 2 to process the steel bar by marking, which can improve the overall practicality of the steel bar limiting device of the marking machine.
