Problems solved by technology
[0003] In the existing steel pipe cutting equipment, when there is cutting, the steel pipe clamping is unstable, so that the cutting piece deviates during the cutting process, resulting in a slope at the cutting edge of the steel pipe; at the same time, steel pipes of different sizes cannot be clamped, and the versatility is poor

The invention relates to a chuck device used for a steel pipe cutting machine. The chuck device used for the steel pipe cutting machine comprises a main base. A U-shaped groove is formed in the main base, and a sliding rod is mounted in the U-shaped groove. An auxiliary base is arranged on the sliding rod and is slidably connected with the sliding rod. The auxiliary base is fixedly connected witha piston rod of a first cylinder. The piston rod of the first cylinder stretches or retreats to control the auxiliary base to slide on the sliding rod. An L-shaped support is fixedly connected to thefront end of the auxiliary base, and a chuck supporting plate is fixedly connected to the L-shaped support. A connecting plate is fixedly connected to the chuck supporting plate. A clamp base is arranged in the chuck supporting plate. A second cylinder is arranged on the clamp base. A piston rod of the second cylinder is fixedly connected with a rack. The rack is slidably connected with the clampbase through a slideway. Wheel teeth are arranged on the two side faces of the rack. Clamping jaws which are engaged with the wheel teeth of the rack are hinged to the two sides of the rack through rotary shafts, are located on the clamp base and are provided with lead screws extending outwards. The lead screws are spiral forwards and reversely. Each lead screw is provided with a set of sliding blocks. The outer ends of the lead screws are driven by rotary knobs so as to be adjusted. The chuck device used for the steel pipe cutting machine can achieve stable clamping and is good in universality.
Description
technical field [0001] The invention belongs to the field of steel pipe cutting equipment, in particular to a chuck device for a steel pipe cutting machine. Background technique [0002] Seamless steel pipe is a long strip of steel with a hollow section and no seams around it. The seamless steel pipe has a hollow section and can be used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile drive shafts. , bicycle racks and steel scaffolding used in building construction, etc. After the seamless steel pipe leaves the factory, the length of the steel pipe is long, and the steel pipe will be cut to length accor...
