Description

Technical Field

[0001] This utility model relates to the field of threaded steel testing technology, and in particular to a threaded steel testing clamping device. Background Technology

[0002] Rebar is the common name for hot-rolled ribbed steel bars. Rebar is widely used in civil engineering construction such as houses, bridges, and roads. From large-scale public facilities such as highways, railways, bridges, culverts, tunnels, flood control, and dams, to small-scale building foundations, beams, columns, walls, and slabs, rebar is an indispensable structural material.

[0003] After the production and processing of rebar, tensile tests are often required. This necessitates clamping and pulling, demanding reliable clamping as well as ease of use. The rebar must be fixed and clamped, with tensile and bending tests being common methods. During these tests, the rebar needs to be clamped. Some existing clamping methods use flat-jaw pliers, which are not convenient for securing the rebar firmly. The small contact area between the pliers and the rebar leads to significant localized pressure during clamping, potentially causing damage such as surface scratches or deformation, affecting stability and the testing results. Therefore, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a threaded steel bar detection clamping device. This device can solve the problem that some existing clamping methods use flat-jaw pliers for fixing, which is not convenient for fixing the threaded steel bar firmly. When using flat-jaw pliers for fixing, the contact area between the flat-jaw pliers and the threaded steel bar is small, resulting in large local pressure during the clamping process. This may cause damage to the threaded steel bar during clamping and processing, such as surface scratches and deformation, affecting the stability of the clamping process and the detection effect of the threaded steel bar.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a threaded steel bar detection clamping device, including a threaded steel bar clamping platform, on which a movable frame and a fixed frame are provided;

A movable block is threadedly sleeved on the surface of the bidirectional threaded rod, and the movable block is slidably connected to the movable frame.

[0007] The surface of the movable block is slidably connected with a threaded steel clamp plate, and the surface of the threaded steel clamp plate is fixedly connected with two clamp plate connecting blocks. Both clamp plate connecting blocks are slidably connected to the movable block. The interior of the movable block is engaged with two fixing pins, which are respectively engaged with the corresponding clamp plate connecting blocks.

[0008] The surface of the movable block is fixedly connected to a limit block. There are two sets of movable blocks, threaded steel plates, plates connecting blocks, fixing pins and limit blocks, which are symmetrically arranged on both sides of the bidirectional threaded rod.

[0009] Preferably, there are two threaded steel clamping assemblies, which are symmetrically arranged on the corresponding movable frame and fixed frame, respectively;

[0010] All four threaded steel clamps are arc-shaped, and multiple threaded steel limiting protrusions are fixedly connected to the surface of each of the four threaded steel clamps. The threaded steel limiting protrusions are serrated.

[0011] Preferably, the surface of the threaded steel clamping platform is provided with a second groove, and a fixing rod is fixedly connected inside the second groove;

[0012] The movable frame is slidably sleeved on the fixed rod, and the movable frame is slidably connected to the inner wall of the second groove. The fixed frame is fixedly connected to the threaded steel clamping platform.

[0013] Preferably, a first support plate is slidably connected to the side of the threaded steel clamping table. The first support plate is U-shaped, and a threaded rod is threadedly connected inside the first support plate. A handle is fixedly connected to the lower end of the threaded rod.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a threaded steel bar detection and clamping device, including a threaded steel bar clamping platform 1, a movable frame 9 and a fixed frame 10 arranged on the threaded steel bar clamping platform 1, and a threaded steel bar clamping assembly. The threaded steel bar clamping assembly is arranged on the threaded steel bar clamping platform 1 and includes a drive motor 11, which is fixedly connected to the movable frame 9. A bidirectional threaded rod 12 is fixedly connected to the output end of the drive motor 11. The bidirectional threaded rod 12 is rotatably connected to the movable frame 9. A movable block 13 is threadedly sleeved on the surface of the bidirectional threaded rod 12, and the movable block 13 slides against the movable frame 9. The movable block 13 is slidably connected to a threaded steel clamp 14. Two clamp connecting blocks 15 are fixedly connected to the surface of the threaded steel clamp 14. Both clamp connecting blocks 15 are slidably connected to the movable block 13. Two fixing pins 16 are engaged inside the movable block 13. The two fixing pins 16 are engaged with the corresponding clamp connecting blocks 15. Limiting blocks 17 are fixedly connected to the surface of the movable block 13. There are two sets of movable blocks 13, threaded steel clamp 14, clamp connecting blocks 15, fixing pins 16 and limiting blocks 17, which are symmetrically arranged on both sides of the bidirectional threaded rod 12.

[0030] There are two threaded steel clamping assemblies, which are symmetrically arranged on the corresponding movable frame 9 and fixed frame 10. The four threaded steel clamping plates 14 are all arc-shaped, and multiple threaded steel limiting protrusions 18 are fixedly connected to the surface of the four threaded steel clamping plates 14. The threaded steel limiting protrusions 18 are serrated.

[0031] The surface of the threaded steel clamping table 1 is provided with a second groove 7. A fixed rod 8 is fixedly connected inside the second groove 7. The movable frame 9 is slidably sleeved on the fixed rod 8. The movable frame 9 is slidably connected to the inner wall of the second groove 7. The fixed frame 10 is fixedly connected to the threaded steel clamping table 1.

[0032] A first support plate 2 is slidably connected to the side of the threaded steel clamping table 1. The first support plate 2 is U-shaped. A threaded rod 4 is threadedly connected inside the first support plate 2. A handle 5 is fixedly connected to the lower end of the threaded rod 4. Multiple first grooves 6 are opened at the lower end of the threaded steel clamping table 1. A second support plate 3 is fixedly connected to the lower end of the first support plate 2. There are four of each of the first support plate 2, second support plate 3, threaded rod 4, and handle 5, which are symmetrically arranged on both sides of the threaded steel clamping table 1. Multiple first grooves 6 are symmetrically arranged on both sides of the threaded steel clamping table 1.

[0033] When using this device, first place the threaded steel bar to be tested for tensile strength between the movable blocks 13, start the drive motor 11 to drive the bidirectional threaded rod 12 to rotate, and the bidirectional threaded rod 12 drives the movable block 13 to slide inside the corresponding movable frame 9 and fixed frame 10, so that the threaded steel bar clamping plate 14 contacts the threaded steel bar. The threaded steel bar limiting protrusion 18 is set to limit the thread on the surface of the threaded steel bar during the contact between the threaded steel bar clamping plate 14 and the threaded steel bar, so as to prevent the threaded steel bar from loosening in the direction of tensile force during the clamping process, thereby improving the stability of the threaded steel bar during clamping and improving the accuracy of the threaded steel bar tensile strength test.

[0034] The movable frame 9 slides on the surface of the fixed rod 8, which facilitates changing the distance between the movable frame 9 and the fixed frame 10 during the tensile testing of the rebar, thus facilitating the tensile testing of the rebar. The rebar clamping plate 14, clamping plate connecting block 15, fixing pin 16 and limiting block 17 are set to facilitate the stability of the rebar clamping plate 14 during the tensile testing of the rebar, facilitate the limiting of the rebar clamping plate 14, and improve the stability of the rebar clamping.

[0035] The setting of the fixing pin 16 facilitates the timely replacement of the threaded steel clamp 14 when the threaded steel limiting protrusion 18 on the surface of the threaded steel clamp 14 wears out. This ensures that the clamp always maintains a good clamping effect, improves the testing accuracy of the threaded steel, and enhances the practicality and flexibility of the clamp.

[0036] The first support plate 2 and the second support plate 3 facilitate the support of the threaded steel clamping platform 1, making it easier to place the clamp on the ground and improving its stability. Simultaneously, the first support plate 2 and the second support plate 3 restrict the clamp's degrees of freedom, serving a positioning function and thus improving the clamp's stability during clamping, ensuring the clamp's firmness and accuracy. Through the sliding connection between the first support plate 2 and the threaded steel clamping platform 1, and the threaded connection between the threaded rod 4 and the first support plate 2, the position of the first support plate 2 is limited by rotating the threaded rod 4 into the corresponding first groove 6. This allows for changing the distance between the first support plate 2 and the second support plate 3 on both sides of the threaded steel clamping platform 1, further improving the stability of the clamp during use.

[0037] By setting up the first support plate 2, the second support plate 3, the threaded rod 4 and the handle 5, the fixture can not only be placed on the ground, but also be fixed on the workbench by using the first support plate 2. Rotating the handle 5 will drive the first groove 6 to rotate inside the first support plate 2, which will facilitate fixing the fixture on the fixed table, improve the convenience and practicality of the fixture, and increase work efficiency.

[0038] Furthermore, the threaded steel clamping plate 14 and the clamping plate connecting block 15 are limited by the limiting block 17 and the fixing pin 16, which facilitates the stability of the threaded steel clamping plate 14 during the tensile test of the threaded steel. At the same time, the use of the threaded steel limiting protrusion 18 increases the friction between the threaded steel clamping plate 14 and the threaded steel, increases the contact area between the threaded steel clamping plate 14 and the threaded steel, prevents the threaded steel from being damaged during the clamping process, improves the clamping effect of the fixture, prevents the threaded steel from loosening along the tensile direction during the clamping process, improves the stability of the threaded steel during clamping, and improves the accuracy of the tensile test of the threaded steel.

[0039] By setting up the first support plate 2, the second support plate 3, the threaded rod 4 and the handle 5, the fixture can not only be placed on the ground, but also be fixed on the workbench by using the first support plate 2. Rotating the handle 5 will drive the first groove 6 to rotate inside the first support plate 2, which will facilitate fixing the fixture on the fixed table, improve the convenience and practicality of the fixture, and increase work efficiency.

[0040] Working principle: When using this device, first place the threaded steel bar to be tested between the movable blocks 13. Start the drive motor 11 to drive the bidirectional threaded rod 12 to rotate. The bidirectional threaded rod 12 drives the movable block 13 to slide inside the corresponding movable frame 9 and fixed frame 10, so that the threaded steel bar clamping plate 14 contacts the threaded steel bar. The threaded steel bar limiting protrusion 18 is set to limit the thread on the surface of the threaded steel bar during the contact between the threaded steel bar clamping plate 14 and the threaded steel bar, preventing loosening along the tensile direction during the clamping process, improving the stability of the threaded steel bar during clamping, and improving the accuracy of the threaded steel bar tensile test.

[0041] The movable frame 9 slides on the surface of the fixed rod 8, which facilitates changing the distance between the movable frame 9 and the fixed frame 10 during the tensile testing of the rebar, thus facilitating the tensile testing of the rebar. The rebar clamping plate 14, clamping plate connecting block 15, fixing pin 16 and limiting block 17 are set to facilitate the stability of the rebar clamping plate 14 during the tensile testing of the rebar, facilitate the limiting of the rebar clamping plate 14, and improve the stability of the rebar clamping.

[0042] The setting of the fixing pin 16 facilitates the timely replacement of the threaded steel clamp 14 when the threaded steel limiting protrusion 18 on the surface of the threaded steel clamp 14 wears out. This ensures that the clamp always maintains a good clamping effect, improves the testing accuracy of the threaded steel, and enhances the practicality and flexibility of the clamp.

[0043] The first support plate 2 and the second support plate 3 facilitate the support of the threaded steel clamping platform 1, making it easier to place the clamp on the ground and improving its stability. Simultaneously, the first support plate 2 and the second support plate 3 restrict the clamp's degrees of freedom, serving a positioning function and thus improving the clamp's stability during clamping, ensuring the clamp's firmness and accuracy. Through the sliding connection between the first support plate 2 and the threaded steel clamping platform 1, and the threaded connection between the threaded rod 4 and the first support plate 2, the position of the first support plate 2 is limited by rotating the threaded rod 4 into the corresponding first groove 6. This allows for changing the distance between the first support plate 2 and the second support plate 3 on both sides of the threaded steel clamping platform 1, further improving the stability of the clamp during use.

[0044] By setting up the first support plate 2, the second support plate 3, the threaded rod 4 and the handle 5, the fixture can not only be placed on the ground, but also be fixed on the workbench by using the first support plate 2. Rotating the handle 5 will drive the first groove 6 to rotate inside the first support plate 2, which will facilitate fixing the fixture on the fixed table, improve the convenience and practicality of the fixture, and increase work efficiency.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
