Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and more specifically, the utility model relates to a jig for steel structure processing. Background Art

[0002] Due to its characteristics such as high strength, light self-weight, and strong deformation ability, steel structures have been widely used. During the processing of steel structures, in order to ensure processing accuracy and quality, the use of jigs is crucial. With the continuous development of industrial technology, the application scenarios of steel structures are becoming increasingly complex and diverse, posing higher requirements for the processing accuracy and efficiency of steel structures. Existing steel structure processing jigs usually consist of structures such as a base, clamping blocks, and threaded columns. When in use, the steel structure workpiece is placed on the base, and then the threaded column is rotated to drive the clamping block to clamp on the side of the steel structure workpiece. Although such jigs can achieve workpiece clamping, often such clamping blocks can only be applicable to steel structure workpieces of specific shapes and sizes, and for workpieces of different specifications, the jigs need to be frequently replaced, resulting in poor practicability of such jigs, increasing production costs and processing time. To solve the deficiencies of the existing technology, we propose a jig for steel structure processing. Summary of the Utility Model

[0005] The clamping assembly includes a clamping table, a positive and negative lead screw is rotatably connected to the middle of the inner wall of the clamping table, a sliding clamp is threadedly connected to the outer surface of the positive and negative lead screw, connecting rods are symmetrically and rotatably connected to the inner surfaces on both sides of the sliding clamp, one end of the connecting rod is rotatably connected to a U-shaped block I, a hollow frame is fixedly installed on the outer surface of one side of the U-shaped block I, an air inlet pipe is fixedly connected to the outer surface of one side of the hollow frame, a hollow cylinder is fixedly installed on the outer surface of the other side of the hollow frame, a ventilation hole is opened on the outer surface of one end of the hollow cylinder, and a clamping column is slidably installed in the inner wall of the hollow cylinder.

[0006] Among them, the clamping table is fixedly installed on the outer surface of the upper side of the base, the sliding clamp slides on the inner cavity surface of the clamping table, the U-shaped block I slides on the inner surface of one side of the clamping table, and the hollow frame is slidably connected to the outer surface of the clamping table.

[0007] Among them, the support component includes an L-shaped seat. A support plate is rotatably connected to the side surface of the L-shaped seat. A second U-shaped block is fixedly installed on the outer surface of one side of the support plate. A cylindrical block is rotatably connected to the inner surface of the second U-shaped block. A cylinder is fixedly installed on the outer surface of the cylindrical block. An auxiliary plate is fixedly installed on one end outer surface of the cylinder. A third U-shaped block is rotatably connected to the outer surface of the auxiliary plate. The L-shaped seat is detachably installed on the upper outer surface of the hollow frame. The third U-shaped block is fixedly installed on the upper surface of one side of the L-shaped seat.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] With the clamping component provided by the present utility model, including a clamping table, first, the connecting pipe of the air pump is fixedly connected to one end of the air inlet pipe. Then, the steel structure workpiece is placed in the middle of the upper outer surface of the base. Next, the positive and negative lead screw is rotated to drive the two sliding clamps to slide relative to each other, thereby driving the connecting rod to rotate, and further driving the two hollow frames to slide relative to each other, so that the outer surface of one end of the clamping column fits on the outer surface of the workpiece. At this time, the air pump is started, so as to push the clamping column to clamp on the outer surface of the workpiece. With the above structure, by providing a plurality of clamping columns and hollow cylinders on the outer surface of one side of the hollow frame, the fixture can clamp steel structure workpieces of different specifications, greatly improving the practicability of the fixture, thereby reducing the production cost and processing time.
