A moving seat is slidably installed on the surface of the mounting rod, and a positioning stop frame is fixedly installed on the tops of the two moving seats. A fixing plate is fixedly installed at the central position of one side of the positioning stop frame.

[0006] Mounting seats are symmetrically and fixedly installed on both sides of the positioning stop frame where it is located on both sides of the fixing plate.

[0007] As a further scheme of the utility model: A cutting machine is fixedly installed at the bottom of the top plate two, and the output end of the cutting machine passes through the top plate two and extends to the top of the top plate two. Mounting frames are symmetrically arranged on both sides of the output end of the cutting machine on the top plate two.

[0008] As a further solution of the utility model: on both sides of the inner wall of the mounting frame, limiting sliding grooves are symmetrically arranged. Between the two ends inside the mounting frame, a sliding rod is fixedly installed. On the surface of the sliding rod, a sliding seat is slidably installed. On both sides of the sliding seat, moving rollers are symmetrically and fixedly installed, and the positions of the moving rollers correspond to those of the limiting sliding grooves. On the top of the sliding seat, a V-shaped seat is fixedly installed. At both ends of the sliding rod, rubber clamping rings are symmetrically and fixedly installed.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For the steel bar cutting equipment for construction with a positioning structure, by setting a scale ruler, a fixed toothed plate, a fixed clamping plate and a compression spring, loosen the fixing bolt, push the positioning stop frame to move on the top of the first top plate, so that the fixed clamping plate slides on the top of the fixed toothed plate, and the fixed toothed plate pushes up the fixed clamping plate to compress the compression spring and deform. After the fixed stop frame moves to a suitable position on the scale ruler, the fixed clamping plate is pressed down by the resilience of the compression spring and is stuck on the top of the fixed toothed plate. Tighten the fixing bolt to connect and fix the positioning clamping plate with the fixed plate, ensuring that the fixed clamping plate is tightly clamped on the top of the fixed toothed plate and will not move randomly, thereby facilitating the adjustment of the distance between the positioning stop frame and the cutting machine and controlling the cutting length of the steel bar.

Specific embodiments

[0020] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a steel bar cutting device for building construction with a positioning structure, including a chassis 1, universal wheels 2 are fixedly installed at the four corners of the bottom of the chassis 1, a first top plate 3 and a second top plate 4 are fixedly installed on the top of the chassis 1, a cutting machine 5 is fixedly installed at the bottom of the second top plate 4, and the output end of the cutting machine 5 passes through the second top plate 4 and extends to the top of the second top plate 4. Mounting racks 6 are symmetrically arranged on both sides of the output end of the cutting machine 5 on the second top plate 4. By providing the cutting machine 5, starting the cutting machine 5 causes the cutting saw blade at the output end of the cutting machine 5 to rotate at a high speed on the top of the second top plate 4. When controlling the steel bar to approach the cutting machine 5, the cutting saw blade cuts the steel bar.

[0022] Limit chutes 7 are symmetrically arranged on both sides of the inner wall of the mounting rack 6. A sliding rod 8 is fixedly installed between the two ends inside the mounting rack 6. A sliding seat 9 is slidably installed on the surface of the sliding rod 8. Moving rollers 10 are symmetrically and fixedly installed on both sides of the sliding seat 9, and the positions of the moving rollers 10 correspond to those of the limit chutes 7. Due to the provision of the limit chutes 7 and the moving rollers 10, the sliding seat 9 is pushed to move on the surface of the sliding rod 8, driving the moving rollers 10 to roll inside the corresponding limit chutes 7, thereby reducing the friction between the sliding seat 9 and the inner wall of the mounting rack 6 and at the same time preventing the sliding seat 9 from deflecting when moving on the surface of the sliding rod 8;

[0023] A V-shaped seat 11 is fixedly installed at the top of the sliding seat 9. Rubber retaining rings 12 are symmetrically and fixedly installed at both ends of the sliding rod 8. By providing the rubber retaining rings 12, when the sliding seat 9 moves to both ends of the sliding rod 8 and is stuck on the surface of the rubber retaining rings 12, the rubber retaining rings 12 are squeezed and deformed between the sliding rod 8 and the sliding seat 9, thereby clamping and fixing the sliding seat 9 on the surface of the sliding rod 8.

[0024] A scale ruler 13 is fixedly installed at the central position of the top of the first top plate 3. Mounting rods 14 are symmetrically and fixedly installed on both sides of the top of the first top plate 3. A moving seat 15 is slidably installed on the surface of the mounting rod 14. And positioning brackets 16 are fixedly installed at the tops of the two groups of moving seats 15. Due to the provision of the scale ruler 13, by pushing the positioning brackets 16 to move on the top of the first top plate 3, according to the position of the positioning brackets 16 on the top of the scale ruler 13, the distance between the positioning brackets 16 and the cutting machine 5 can be adjusted.

[0025] A positioning baffle 17 is provided on one side of the positioning bracket 16 away from the fixing plate 20. And fixing hooks 18 are respectively fixedly installed on the surfaces of the positioning bracket 16 on both sides of the positioning baffle 17. Fixed toothed plates 19 are symmetrically and fixedly installed on both sides of the scale ruler 13 at the top of the first top plate 3. By providing the fixing hooks 18, the positioning baffle 17 is correspondingly inserted into the positioning bracket 16, so that the fixing hooks 18 can clamp and fix the positioning baffle 17 inside the positioning bracket 16.

[0026] A fixing plate 20 is fixedly installed at the central position of one side of the positioning bracket 16; a positioning card plate 28 is fixedly installed at the central position of the bottom of the connecting plate 27. Fixing bolts 29 are symmetrically provided at the bottom of one side of the positioning card plate 28, and the fixing bolts 29 pass through the positioning card plate 28 and are connected to the fixing plate 20. Due to the provision of the fixing plate 20 and the fixing bolts 29, by screwing the fixing bolts 29 to fix the positioning card plate 28 at different heights of the fixing plate 20, the connecting plate 27 drives the moving rod 23 to move, so that the fixing card plate 24 moves away from the fixed toothed plate 19, facilitating the movement of the positioning bracket 16 on the top of the first top plate 3.

[0027] Mounting seats 21 are symmetrically and fixedly installed on both sides of the positioning bracket 16 where the fixing plate 20 is located. A limiting plate 22 is slidably installed inside the mounting seat 21. A moving rod 23 is fixedly installed at the central position of the limiting plate 22, and both ends of the moving rod 23 penetrate through the mounting seat 21. The bottom end of the moving rod 23 passes through the mounting seat 21 and is fixedly installed with a fixing card plate 24. A compression spring 26 is provided on the surface of the moving rod 23 above the limiting plate 22. The tops of the two groups of moving rods 23 pass through the mounting seat 21 and are fixedly installed with a connecting plate 27. By providing the compression spring 26, under the elastic action of the compression spring 26, the limiting plate 22 is pressed against the inner bottom of the mounting seat 21, so that the fixing card plate 24 can be pressed down and clamped on the top of the fixed toothed plate 19.

[0028] The shape of the fixed clamping plate 24 corresponds to that of the fixed toothed plate 19. Limit rods 25 are fixedly installed at the four corners of the top of the fixed clamping plate 24, and the limit rods 25 are slidably connected to the mounting base 21. Due to the provision of the limit rods 25, when the fixed clamping plate 24 moves up and down at the bottom of the mounting base 21, the limit rods 25 move synchronously at the bottom of the mounting base 21 to ensure that the fixed clamping plate 24 does not deflect when moving at the bottom of the mounting base 21.

[0029] The working principle of the present utility model is as follows:

[0030] After the positioning baffle 17 is snapped into one side of the positioning bracket 16, the fixing bolt 29 is loosened, and the positioning bracket 16 is pushed to move on the top of the first top plate 3, so that the fixed clamping plate 24 slides over the teeth on the top of the fixed toothed plate 19. The teeth on the top of the fixed toothed plate 19 push up the fixed clamping plate 24, and under the rebounding action of the compression spring 26, the fixed clamping plate 24 is always pressed tightly on the top of the fixed toothed plate 19. After the positioning bracket 16 is pushed to a suitable position on the scale ruler 13 according to the cutting requirement, the fixed clamping plate 24 moves down and clamps tightly on the top of the fixed toothed plate 19, and the fixing bolt 29 is tightened to fix the positioning bracket 16 on the top of the first top plate 3. The steel bar is placed on the tops of the two V-shaped seats 11. After the steel bar is pressed against the positioning baffle 17, the cutting machine 5 is started, and the steel bar is pushed to drive the two sliding seats 9 to slide away from the rubber retaining ring 12 on the surface of the sliding rod 8 and approach the cutting machine 5, so that the cutting machine 5 can cut the steel bar to ensure that the cut steel bar meets the requirements.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0032] The above describes the preferred embodiments of the present patent in detail, but the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present patent.
