Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and specifically relates to a positioning fixture and a steel bar cutting machine thereof. Background Art

[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete, with a circular cross-section, and sometimes a square cross-section with rounded corners.

[0003] The prior art (publication number: CN220444928U) discloses a steel bar positioning fixture, which relates to the technical field of steel bar processing. In order to solve the defect that the cutting position of the steel bar cannot be automatically adjusted as required in the prior art, the proposed steel bar positioning fixture includes a bottom plate and a second platform, and a second rubber block is fixedly installed on the top of the second platform.

[0004] The prior art clamps the steel bar on the device through two sets of structures that can move above and the fixed structure below and cooperates with a cutting machine to cut the steel bar. Although the prior art can cut the steel bar, when the cutting size is smaller than the steel bar on the top of the fixed structure below in the prior art, cutting cannot be carried out because the steel bar is blocked by the moving structure above. Therefore, the applicable range of the prior art is small.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0006] In order to solve the technical problem of the small applicable range of the above-mentioned prior art, the basic concept of the technical solution adopted by the present utility model is as follows:

[0007] A positioning fixture, comprising:

[0008] A base plate, on the top of which support plates are symmetrically and fixedly connected. On the top of one of the support plates, a sliding column is fixedly connected. The sliding column is cylindrical, and side rods are symmetrically and fixedly connected to the wall surfaces between the symmetric support plates.

[0009] A fixed structure, which can facilitate the cutting of the steel bar. The fixed structure includes limit rods, clamping plates, fixed rods, movable plates and movable rods. The limit rods are symmetrically and movably connected above the side rods. The clamping plates are slidably connected between the symmetric limit rods. The fixed rods are fixedly connected to the wall surfaces of the support plates between the symmetric side rods. The movable plates are movably connected to the bottoms of the fixed rods. The movable rods are fixedly connected to the tops of the movable plates. A plurality of fixed rods are arranged between the symmetric side rods, and the movable rods can pass through between each adjacent pair of fixed rods.

[0010] As a preferred embodiment of the present utility model, the clamping plate is composed of a plurality of arc-shaped plates. The fixed rod is composed of a rectangular rod in the lower half and an isosceles trapezoidal rod in the upper half. The movable rods are respectively arranged between each adjacent pair of fixed rods. The movable plate can be fixedly connected to the bottoms of all the movable rods, and the tops of the movable rods are arc-shaped.

[0011] As a preferred embodiment of the present utility model, the fixing structure further includes sliders, sliding grooves, triggering grooves, triggering boxes, spring grooves and connecting grooves. The sliders are fixedly connected to both ends of the limiting rods. Circular grooves adapted to the sliding columns are formed at the tops of the sliders. The sliders can vertically slide along the wall surfaces of the sliding columns through the circular grooves. The sliding grooves are formed on the mutually facing wall surfaces of the symmetric limiting rods. The triggering grooves are symmetrically formed at the tops of each side rod. The triggering boxes are symmetrically and fixedly connected to the mutually facing wall surfaces of the symmetric supporting plates. The spring grooves are formed in the cavities of the triggering boxes. The connecting grooves are formed on the front wall surfaces of the triggering boxes.

[0012] As a preferred embodiment of the present utility model, the fixing structure further includes triggering blocks, clamping blocks and connecting blocks. The triggering blocks are elastically connected in the spring grooves through springs. The bottoms of the sliders can contact the tops of the triggering blocks. The clamping blocks are symmetrically and fixedly connected to the two side wall surfaces of the triggering blocks. The connecting blocks are slidably connected in the connecting grooves.

[0013] As a preferred embodiment of the present utility model, the tops of the triggering blocks can pass through the tops of the triggering boxes and then through the triggering grooves. The spring grooves can adapt to the wall surfaces where the triggering blocks and the symmetric clamping blocks slide and connect. The wall surfaces are also fixedly connected to the wall surfaces of the movable plates. Each triggering box is provided with a spring groove, a triggering block, a clamping block, a connecting groove and a connecting block.

[0014] As a preferred embodiment of the present utility model, the fixing structure further includes an adjusting plate, a pointer and a cutting groove. The adjusting plate is slidably connected in the limiting rod. The pointer is fixedly connected to the top of the adjusting plate. The cutting groove is formed on the top of the adjusting plate. The bottom of the adjusting plate can contact the bottom of the clamping plate. The pointer and the cutting groove are on the same horizontal line.

[0015] A steel bar cutting machine includes a cutting machine body and all the positioning jigs described above.

[0016] The present utility model has the following beneficial effects compared with the prior art:

[0017] 1. By setting the fixing structure, it can adapt to steel bars of different sizes for cutting. Because when the steel bar is placed on the top of the fixing rod, it will cooperate with the clamping plate to clamp and fix the end of the steel bar, and it is not necessary to adjust the position of the steel bar during cutting. Therefore, compared with the prior art, the application range of this solution is wider.

[0029] As Figure 1 and Figure 2 shown, a positioning fixture includes: a substrate 20, support plates 21 are symmetrically and fixedly connected to the top of the substrate 20, a sliding column 22 is fixedly connected to the top of one of the support plates 21, the sliding column 22 is cylindrical, side rods 23 are symmetrically and fixedly connected to the wall surface between the symmetric support plates 21, a hydraulic rod is installed at the top of the sliding column 22, and the hydraulic rod is electrically connected to the corresponding power supply. This is an existing technology and will not be elaborated here.

[0030] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixing structure can facilitate the cutting of steel bars. The fixing structure includes a limiting rod 31, clamping plates 32, a fixing rod 37, a movable plate 38 and a movable rod 39. The limiting rod 31 is symmetrically and movably connected above the side rods 23. The clamping plates 32 are slidably connected between the symmetric limiting rods 31. The fixing rod 37 is fixedly connected to the wall surface of the support plate 21 between the symmetric side rods 23. The movable plate 38 is movably connected to the bottom of the fixing rod 37. The movable rod 39 is fixedly connected to the top of the movable plate 38. A plurality of fixing rods 37 are arranged between the symmetric side rods 23, and the movable rod 39 can pass through between each adjacent fixing rod 37.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the clamping plates 32 are composed of a plurality of arc-shaped plates. The fixing rod 37 is composed of a rectangular rod in the lower half and an isosceles trapezoidal rod in the upper half. The movable rods 39 are respectively arranged between each adjacent fixing rod 37. The movable plate 38 can be fixedly connected to the bottoms of all the movable rods 39. The top of the movable rod 39 is in an arc shape. The fixing structure further includes a slider 30, a chute 33, a trigger groove 40, a trigger box 41, a spring groove 42 and a connecting groove 45. The slider 30 is fixedly connected to both ends of the limiting rod 31. A circular groove adapted to the sliding column 22 is provided at the top of the slider 30. The slider 30 can vertically slide along the wall surface of the sliding column 22 through the circular groove. The chute 33 is opened on the mutually facing wall surfaces of the symmetric limiting rods 31. The trigger groove 40 is symmetrically opened at the top of each side rod 23. The trigger box 41 is symmetrically and fixedly connected to the mutually facing wall surfaces of the symmetric support plates 21. The spring groove 42 is opened in the cavity of the trigger box 41. The connecting groove 45 is opened on the front wall surface of the trigger box 41. The fixing structure further includes a trigger block 43, a clamping block 44 and a connecting block 46. The trigger block 43 is elastically connected in the spring groove 42 by a spring. The bottom of the slider 30 can contact the top of the trigger block 43. The clamping blocks 44 are symmetrically and fixedly connected to the two side wall surfaces of the trigger block 43. The connecting block 46 is slidably connected in the connecting groove 45. The top of the trigger block 43 can pass through the top of the trigger box 41 and pass through the trigger groove 40. The spring groove 42 can adapt to the sliding of the trigger block 43 and the symmetric clamping blocks 44. The wall surface of the connecting block 46 is also fixedly connected to the wall surface of the movable plate 38. Each trigger box 41 is provided with a spring groove 42, a trigger block 43, a clamping block 44, a connecting groove 45 and a connecting block 46;

[0032] During specific use, the hydraulic rod is connected to the top of the slider 30. First, place the steel bar to be clamped on the top of the fixed rod 37. At this time, the steel bar will be located between the adjacent movable rods 39 and on the top of the fixed rod 37. After the steel bar is placed, turn on the power of the hydraulic rod. The hydraulic rod will push the slider 30 downward, and the slider 30 will slide along the wall surface of the sliding column 22. The slider 30 will drive the limit rod 31 to slide downward at the same time. The limit rod 31 will drive the clamping plate 32 to slide. When the bottom of the clamping plate 32 contacts the top of the steel bar, the hydraulic rod stops operating. At this time, the steel bar will be clamped between the clamping plate 32 and the fixed rod 37. When the clamping plate 32 is about to clamp the steel bar, the bottom of the slider 30 will contact the top of the trigger block 43 and push the trigger block 43 downward. When the trigger block 43 moves downward, it will drive the movable plate 38 and the movable rod 39 to move downward at the same time through the connecting block 46. At this time, the spring at the bottom of the trigger block 43 will be compressed, and the movable rod 39 will move downward from the space between the adjacent fixed rods 37. When the clamping plate 32 clamps the steel bar, the steel bar will be located between the bottom of the clamping plate 32 and the top of the fixed rod 37. At this time, the steel bar can be cut. After the cutting is completed, control the hydraulic rod to retract, which will drive the clamping plate 32 to move upward to cancel the clamping of the steel bar. After canceling the clamping of the steel bar, the trigger block 43 will drive the movable rod 39 to move back into the space between the fixed rods 37 through the spring at the bottom;

[0033] In summary, by setting the fixing structure, it can adapt to steel bars of different sizes for cutting. Because when the steel bar is placed on the top of the fixed rod 37, the end of the steel bar will be clamped and fixed in cooperation with the clamping plate 32, and it is possible to cut the steel bar without adjusting the position of the steel bar. Therefore, compared with the prior art, the applicable range of this solution is wider.

[0034] As Figure 1 and Figure 5 shown, the fixing structure further includes an adjusting plate 34, a pointer 35 and a cutting groove 36. The adjusting plate 34 is slidably connected inside the limit rod 31. The pointer 35 is fixedly connected to the top of the adjusting plate 34. The cutting groove 36 is opened on the top of the adjusting plate 34. The bottom of the adjusting plate 34 can contact the bottom of the clamping plate 32. The pointer 35 and the cutting groove 36 are on the same horizontal line;

[0035] During specific use, a length scale is provided above the limit rod 31. After the steel bar is fixed by the clamping plate 32, slide the adjusting plate 34 along the limit rod 31 to the required cutting length and stop. The pointer 35 will point to the scale on the top of the limit rod 31. At this time, the steel bar can be cut from the cutting groove 36;

[0036] In summary, by setting the cutting groove 36, it can clearly frame the position corresponding to the cutting length when cutting the steel bar, so as to facilitate accurate cutting of the length of the steel bar.

[0037] A steel bar cutting machine, not shown in the figure, includes a cutting machine body and all the above-mentioned positioning jigs. After the steel bar is fixed by the positioning jig, the cutting machine body can cut the clamped steel bar.

[0038] By setting the positioning jig, the applicable range of the steel bar cutting machine can be improved, and the required length can be quickly cut when cutting the steel bar.

[0039] Working principle: The hydraulic rod is connected to the top of the slider 30. First, place the steel bar to be clamped on the top of the fixed rod 37. At this time, the steel bar will be located between the adjacent movable rods 39 and on the top of the fixed rod 37. After the steel bar is placed, turn on the power supply of the hydraulic rod. The hydraulic rod will push the slider 30 downward. The slider 30 will slide along the wall surface of the sliding column 22. The slider 30 will drive the limiting rod 31 to slide downward at the same time. The limiting rod 31 will drive the clamping plate 32 to slide. When the bottom of the clamping plate 32 contacts the top of the steel bar, the hydraulic rod stops operating. At this time, the steel bar will be clamped between the clamping plate 32 and the fixed rod 37. When the clamping plate 32 is about to clamp the steel bar, the bottom of the slider 30 will contact the top of the trigger block 43 and push the trigger block 43 downward. When the trigger block 43 moves downward, it will drive the movable plate 38 and the movable rod 39 to move downward at the same time through the connecting block 46. At this time, the spring at the bottom of the trigger block 43 will be compressed, and the movable rod 39 will move downward from the space between the adjacent fixed rods 37. When the clamping plate 32 clamps the steel bar, the steel bar will be between the bottom of the clamping plate 32 and the top of the fixed rod 37. At this time, the steel bar can be cut. After the cutting is completed, control the hydraulic rod to retract, which will drive the clamping plate 32 to move upward to cancel the clamping of the steel bar. After canceling the clamping of the steel bar, the trigger block 43 will drive the movable rod 39 to move back into the space between the fixed rods 37 through the spring at the bottom.
