Description

Technical Field

[0001] The utility model relates to the field of steel structure processing, in particular to a steel structure drilling fixture. Background Art

[0002] Drilling device is a general term for equipment used to make holes in solid materials. Common drilling devices include electric drills, drilling machines, etc. With the further development of processing technology, the efficiency of drilling devices has also been greatly improved. When drilling holes in steel structures, it is usually necessary to clamp and fix the steel structures with a fixture first.

[0003] However, when drilling holes in the cross plate of the T-shaped steel, the downward pressure of the drilling tool is too large, which will cause the cross plate of the T-shaped steel to deform and tilt downward. In addition, the cross plate of the T-shaped steel has no parts for supporting it. The cross plate of the T-shaped steel is usually supported by the top of the clamping plate, which causes the distance between the T-shaped steel and the fixture table to be too close, making it difficult for the drilling tool to penetrate the bottom, resulting in incomplete holes that do not meet the standards. Therefore, those skilled in the art provide a drilling fixture for steel structures to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a drilling fixture for steel structures, including a fixture table, the fixture table is equipped with a clamping plate, the fixture table is equipped with a first handle, the top of the fixture table is fixedly connected with connecting walls on both sides, the connecting walls are provided with support blocks, the bottom of the support blocks is fixedly connected with a connecting longitudinal rod, the connecting longitudinal rod is fixedly connected with a connecting cross rod, and both ends of the connecting cross rod are fixedly connected with lifting plates.

[0005] Preferably: the splint is provided with a protective pad, and the bottom of the fixture table is fixedly connected with a base.

[0006] Preferably, the distance between the support block and the splint is greater than 1 cm.

[0007] Preferably, the lifting plate is provided with a notch, the notch is fixedly connected with a rack, and the rack is meshingly connected with a gear.

[0008] Preferably: a protective cover is provided outside the lifting plate, the protective cover is slidably connected to the lifting plate, and the protective cover is fixedly connected to the fixture table.

[0009] Preferably: the two gears are commonly fixedly connected with a connecting rod, the connecting rod is rotatably connected to the fixture table, and the connecting rod is fixedly connected with a second rotary handle.

[0010] Technical effects and advantages of the utility model:

[0011] Place the T-shaped steel on the fixture table, and place the two ends of the top horizontal plate of the T-shaped steel on the supporting blocks on both sides respectively. The two clamping plates clamp the longitudinal plates of the T-shaped steel to fix the T-shaped steel, and then use the drilling tool to drill holes on the horizontal plates of the T-shaped steel. Since there are supporting blocks at the bottom of both ends of the horizontal plates of the T-shaped steel for support, the horizontal plates will not be deformed by the downward force when drilling;

[0012] Rotating the second knob drives the connecting rod and the gear to rotate, and the gear meshing with the rack drives the entire lifting plate to rise and fall, and the lifting plate further drives the connecting cross bar, the connecting longitudinal bar and the supporting block to rise and fall, so as to facilitate the adjustment of the height of the T-shaped steel cross plate, thereby adjusting the distance between the cross plate and the fixture table, avoiding the difficulty of drilling tools to penetrate due to the short distance between the cross plate and the fixture table, and ensuring that the hole meets the standard.
