Wedge (voussoir) clamp mechanism is to utilize the ramp effect clamping work pieces, and it is simple in structure, and is easily manufactured, be swift in motion easy, but for guaranteeing wedge block self-locking, during clamping, effort is larger.Screw clamping mechanism is to utilize the axial force clamping work pieces that produces when rotating spiral, and it is simple in structure, and clamping force is large, safe and reliable, and large impulse stroke is arranged, adaptability is large, normal unite use with the lever pressing plate, but clamp at every turn and when unclamping workpiece the rotation spiral action slow, operation is wasted time and energy.Eccentric clamp system is the self-locking action clamping work pieces that utilizes eccentric wheel or cam, be swift in motion, but clamping force little (little more a lot of than helical clamping power) clamps stroke little, and reliability is relatively poor.
In prior art, the clamp mechanism effect is single, can't process simultaneously the pipe of different-diameter, and automaticity is low, the very trouble that operates, inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of pipe that can process simultaneously different-diameter is provided, and automaticity is high, pipe beveler clamp mechanism easy to operate.
According to the technical scheme that the utility model provides, a kind of pipe beveler clamp mechanism comprises that oil cylinder, oil cylinder arranged outside have framework, framework upper end that oil cylinder is covered, and the first support bar penetrates the position that oil cylinder and framework overlap and three's relative position is fixed; The oil cylinder lower end is provided with suspension bracket, and the second support bar penetrates position that oil cylinder lower end and suspension bracket overlap and fixing three's relative position; The first support bar be connected two ends, support bar left and right and all connect by spring, spring is positioned at oil cylinder both sides;
The suspension bracket inboard is fixed with leading truck, and the framework inboard is provided with guide post, and guide post penetrates leading truck, is positioned at leading truck, in order to guiding; Described leading truck and guide post are orthogonal, all are positioned at the oil cylinder inboard;
The suspension bracket lower end is fixed with fixture block, and lower fixture block is fixed in the framework lower end, and the up and down, position of upper fixture block and lower fixture block is corresponding, and moves up and down by fixture block in the flexible drive of oil cylinder.
Described framework is the type of falling C structure, is fixed by screws on reduction box, and cutterhead is installed in the hollow part.
Described leading truck, upper fixture block and lower fixture block all by soket head cap screw fix with counter structure on.
The size of described lower fixture block can be changed according to different pipe diameters.
The utlity model has following advantage: the utility model is simple, compact and reasonable for structure; Utilize the upper fixture block of the flexible drive of oil cylinder to move up and down, reach the purpose that clamps different pipes by the lower fixture block of changing different size, very convenient and practical in operation.
