Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the drawings:

[0016] Such as Figure 1-3 As shown, a simple three-jaw centering fixture for steel pipe processing includes a cylindrical steel pipe 1. Three fixing nuts 2 are uniformly distributed on the outer surface of the cylindrical steel pipe 1 on the same circumference. The fixing nuts 2 are respectively provided with adjusting bolts 3. A cylindrical clamping disc 4 is provided at one end of the cylindrical steel pipe 1, and a central hole 5 communicating with the interior of the cylindrical steel pipe 1 is opened in the center of the cylindrical clamping disc 4.

[0017] Such as Figure 1-3 As shown, a simple three-jaw centering fixture for steel pipe processing, the fixing nut 2 is welded to the outer surface of the cylindrical steel pipe 1; the cylindrical clamping plate 4 and the cylindrical steel pipe 1 are fixed by welding, and the cylindrical clamping plate 4 It is on the same axis as ...

Abstract

The invention discloses a simple three-claw centering clamp for steel pipe machining, and belongs to the technical field of machine manufacturing. The simple three-claw centering clamp comprises a cylindrical steel pipe. Three fixing nuts are evenly distributed on the same circumference of the outer circle surface of the cylindrical steel pipe. Adjusting bolts are arranged in the fixing nuts correspondingly. A cylindrical clamping disc is arranged at one end of the cylindrical steel pipe. A center hole communicating with the interior of the cylindrical steel pipe is formed in the center of the cylindrical clamping disc. The simple three-claw centering clamp is simple in structure, the work principle is clear, and the basic function of steel pipe clamping is achieved. Through the interaction of the adjusting bolts and the fixing nuts, steel pipe clamping center alignment and fine adjustment are achieved, and the steel pipe machining precision is improved. The clamp manufacturing cost is extremely low, operation is easier, and later maintaining on the clamp is not needed.

Description

Technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a clamp, in particular to a simple three-jaw centering clamp for steel pipe processing. Background technique [0002] The use of ordinary steel pipes is more common in daily life. In special industries such as electric power, metallurgy, mining, coal, petrochemicals, etc., in order to meet the requirements of its diameter, wear resistance, corrosion resistance, and high (low) temperature resistance, it is necessary to provide some Special performance steel pipes, and these steel pipes need to be specially processed or treated. To process steel pipes of different diameters, special fixtures are required to clamp the steel pipes before rotating processing, but the rotation center of the clamped steel pipes High precision requirements. Currently, three-jaw self-centering chucks are the main fixtures for holding steel pipes. However, the cost of manufacturing such fixtures...
