Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, specifically a drilling fixture for steel structure components. Background Technology

[0002] Steel structural components are steel beams, steel columns, steel trusses, and other components made of steel profiles and steel plates, which are connected by welding, riveting, or bolting to form an integral structure. They are characterized by their light weight, simple construction, high strength, and strong plasticity. According to their uses, they can be divided into building steel structures, equipment steel structures, bridge steel structures, marine steel structures, space frame steel structures, and hydraulic steel structures, and are widely used in various fields.

[0003] During the processing of steel structural components, drilling is required according to the processing technology requirements. In order to improve the quality and efficiency of drilling, appropriate drilling jigs are needed to hold the steel structural components. However, in actual use, most existing jigs hold the steel structural components by clamping blocks. Although this clamping method has a good fixing effect for steel structural components with regular shapes, it has a poor fixing effect for some irregularly shaped steel structural components, which will affect the drilling quality. Therefore, it is necessary to improve this method. Utility Model Content

[0004] The purpose of this utility model is to address the above problems. This utility model provides a drilling fixture for steel structural components, which has the advantage of being easy to clamp irregularly shaped steel structural components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling fixture for steel structural components, comprising a placement platform, a fixed box fixedly installed on the right side of the top of the placement platform, a cylinder fixedly installed on the left end of the fixed box, a clamping rod movably sleeved inside the cylinder, the right end of the clamping rod penetrating through the fixed box and extending into the interior of the fixed box, a piston plate movably sleeved on the right end inside the fixed box, a crossbar fixedly installed in the middle of the right end of the piston plate, the right end of the crossbar penetrating through the fixed box and extending to the outside of the fixed box and fixedly installed with a vertical rod, a connecting rod hinged to the bottom end of the vertical rod, the left side of the top end of the connecting rod movably connected to the bottom end of the placement platform, a drive motor fixedly installed on the right side of the bottom end of the placement platform, a drive shaft fixedly sleeved on the other end of the output shaft of the drive motor, a disc fixedly sleeved on the top of the outer surface of the drive shaft, the right side of the top end of the disc hinged to the left end of the connecting rod.

[0006] As a preferred embodiment of this utility model, a limiting groove is formed at the top of the inner surface of the cylinder, a limiting block is movably sleeved at the right end inside the limiting groove, and the outer surface of the limiting block is fixedly connected to the outer surface of the clamping rod.

[0007] As a preferred embodiment of this utility model, a limiting rod is fixedly installed at the right end of the placement platform. The right end of the limiting rod passes through the vertical rod and extends to the outside of the vertical rod, and a baffle is fixedly sleeved thereon. The outer surface of the baffle is movably connected to the outer surface of the vertical rod.

[0008] As a preferred embodiment of this utility model, mounting plates are fixedly installed on the front and rear sides of the bottom of the placement platform, a side plate is fixedly installed on the left end of the mounting plate, and the right end of the side plate is fixedly connected to the left end of the placement platform.

[0009] As a preferred embodiment of this utility model, a T-shaped block is fixedly installed at the middle of the top of the side plate, and a positioning plate is movably sleeved on the outer surface of the T-shaped block, with the bottom end of the positioning plate movably connected to the top end of the side plate.

[0010] As a preferred embodiment of this utility model, a diagonal rod is hinged to the left side of the bottom end of the positioning plate, and a movable block is hinged to the other end of the diagonal rod. The outer surface of the movable block and the inner surface of the side plate are movably connected.

[0011] As a preferred embodiment of this utility model, a power motor is fixedly installed at the bottom of the side plate, and a threaded rod is fixedly sleeved at the other end of the output shaft of the power motor, with the top of the outer surface of the threaded rod and the inner surface of the movable block threadedly sleeved together.

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

[0013] 1. This utility model, by setting up a fixed box, clamping rod, piston plate, connecting rod and disc, when the drive motor starts, the drive shaft will drive the disc to rotate, thereby causing the connecting rod hinged to the disc to rotate as well. This causes the other end of the connecting rod to generate a pulling force on the vertical rod, pulling the vertical rod through the horizontal rod and moving the piston plate. This causes the piston plate to compress the air inside the fixed box, thereby pushing out the clamping rod, thus facilitating the clamping and fixing of irregularly shaped steel structural components.

[0014] 2. This utility model, by setting up a T-block, a positioning plate, a diagonal rod, a movable block, and a threaded rod, will cause the threaded rod to rotate when the power motor is started. Since the outer surface of the threaded rod and the inner surface of the movable block are threaded together, the movable block will move along the inner surface of the side plate under the action of the threaded rod. This will cause the diagonal rod to exert a pulling force on the positioning plate, pulling the positioning plate along the outer surface of the T-block, thereby realizing the adjustment of the drilling position.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a drilling fixture for steel structural components, including a placement platform 1. A fixed box 2 is fixedly installed on the right side of the top of the placement platform 1. A cylinder 3 is fixedly installed on the left side of the fixed box 2. A clamping rod 4 is movably sleeved inside the cylinder 3. The right end of the clamping rod 4 passes through the fixed box 2 and extends into the interior of the fixed box 2. A piston plate 5 is movably sleeved on the right side of the interior of the fixed box 2. A crossbar 6 is fixedly installed in the middle of the right end of the piston plate 5. The right end of the crossbar 6 passes through the fixed box 2 and extends to the outside of the fixed box 2 and is fixedly installed with a vertical rod 7. A connecting rod 8 is hinged to the bottom end of the vertical rod 7. The left side of the top of the connecting rod 8 is movably connected to the bottom end of the placement platform 1. A drive motor 9 is fixedly installed on the right side of the bottom end of the placement platform 1. A drive shaft 10 is fixedly sleeved on the other end of the output shaft of the drive motor 9. A disc 11 is fixedly sleeved on the top of the outer surface of the drive shaft 10. The right side of the top of the disc 11 is hinged to the left end of the connecting rod 8.

[0023] The cylinders 3 are evenly distributed on the outer surface of the fixed box 2. When the drive motor 9 is started, the drive shaft 10 will drive the disc 11 to rotate. Since the left and right ends of the connecting rod 8 are hinged to the disc 11 and the vertical rod 7 respectively, the left end of the connecting rod 8 will rotate along with the disc 11, thereby generating a pulling force on the vertical rod 7 at the other end of the connecting rod 8. This pulls the vertical rod 7, causing the horizontal rod 6 and the piston plate 5 to move. This causes the piston plate 5 to compress the air inside the fixed box 2, increasing the pressure inside the fixed box 2. As a result, the clamping rod 4 is pushed out of the cylinder 3, thus clamping and fixing the irregularly shaped steel structure through the clamping rod 4.

[0024] Among them, a limiting groove 12 is opened at the top of the inner surface of the cylinder 3, and a limiting block 13 is movably sleeved at the right end inside the limiting groove 12. The outer surface of the limiting block 13 is fixedly connected to the outer surface of the clamping rod 4.

[0025] The cooperation between the limiting groove 12 and the limiting block 13 will restrict the movement of the clamping rod 4, thereby preventing the clamping rod 4 from separating from the cylinder 3.

[0026] Among them, a limiting rod 14 is fixedly installed on the right end of the placement platform 1. The right end of the limiting rod 14 passes through the vertical rod 7 and extends to the outside of the vertical rod 7 and is fixedly sleeved with a baffle 15. The outer surface of the baffle 15 is movably connected to the outer surface of the vertical rod 7.

[0027] The presence of the limiting rod 14 and the baffle 15 will limit the movement of the vertical rod 7, thereby ensuring the stability of the movement of the vertical rod 7.

[0028] Mounting plates 16 are fixedly installed on the front and rear sides of the bottom of the placement platform 1, a side plate 17 is fixedly installed on the left end of the mounting plate 16, and the right end of the side plate 17 is fixedly connected to the left end of the placement platform 1.

[0029] The presence of mounting plate 16 and side plate 17 will provide support and fixation.

[0030] Among them, a T-shaped block 18 is fixedly installed in the middle of the top of the side plate 17, and a positioning plate 19 is movably sleeved on the outer surface of the T-shaped block 18. The bottom end of the positioning plate 19 is movably connected to the top end of the side plate 17.

[0031] Both the outer surface of the T-block 18 and the inner surface of the positioning plate 19 are smooth, thus ensuring that the positioning plate 19 will not get stuck when moving along the outer surface of the T-block 18.

[0032] The bottom left side of the positioning plate 19 is hinged with a diagonal rod 20, and the other end of the diagonal rod 20 is hinged with a movable block 21. The outer surface of the movable block 21 and the inner surface of the side plate 17 are movably connected.

[0033] When the movable block 21 moves along the inner surface of the side plate 17 with the diagonal rod 20, the diagonal rod 20 will exert a pulling force on the positioning plate 19, causing the positioning plate 19 to move.

[0034] The bottom of the side plate 17 is fixedly installed with a power motor 22, and the other end of the output shaft of the power motor 22 is fixedly sleeved with a threaded rod 23. The top of the outer surface of the threaded rod 23 is threadedly sleeved with the inner surface of the movable block 21.

[0035] When the power motor 22 is started, the threaded rod 23 will rotate. Since the outer surface of the threaded rod 23 and the inner surface of the movable block 21 are threaded together, the movable block 21 will move along the inner surface of the side plate 17.

[0036] Working principle and usage process of this utility model:

[0037] First, the operator places the steel structure to be processed on the top of the placement platform 1, and then starts the drive motor 9, which causes the drive shaft 10 to drive the disc 11 and one end of the connecting rod 8 to rotate. This causes the other end of the connecting rod 8 to exert a pulling force on the vertical rod 7, pulling the vertical rod 7 and moving the horizontal rod 6 and piston plate 5. This causes the piston plate 5 to compress the air inside the fixing box 2, increasing the pressure inside the fixing box 2. This causes the clamping rod 4 to be pushed out of the cylinder 3, and then the different clamping rods 4 to fit tightly against the outer surface of the steel structure. This allows for the clamping and fixing of irregularly shaped steel structures, thereby improving the applicability of the drilling fixture.

[0038] When the drilling position needs to be adjusted, the operator starts the power motor 22, causing the threaded rod 23 to rotate. This causes the movable block 21, which is threadedly connected to the threaded rod 23, to move along the inner surface of the side plate 17, along with the bottom end of the inclined rod 20. This causes the top end of the inclined rod 20 to exert a pulling force on the positioning plate 19, pulling the positioning plate 19 along the outer surface of the T-block 18 until the round hole at the top of the positioning plate 19 aligns with the position to be drilled. Then the operator can start the drilling operation, thus achieving the adjustment of the drilling position and improving the convenience of using the drilling fixture.
