In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: synchronous clamp system of awl tube closing-in and bonding machine, comprise the oil cylinder that links to each other with hydraulic system, radially on the vertical plane of Taper Pipe axis be evenly distributed with at least three depression bars, described depression bar is movably connected on the housing and can stretches at its axis of described vertical plane upper edge, described oil cylinder has two, the piston rod of these two oil cylinders links to each other with two depression bars wherein respectively, every depression bar is provided with a toothed rack, every toothed rack is meshed with a gear on being fixed on described housing, every gear is coaxially installed with a sprocket wheel, and all sprocket wheels link to each other by a chain.
Further, the cross section of described housing is a regular hexagon, and described depression bar has the six roots of sensation, respectively perpendicular to six sides of described housing.Roller is equipped with in the end of described depression bar.Two depression bars described and that the piston rod of oil cylinder links to each other respectively are symmetricly set on the described housing.
In the present invention, the depression bar that links to each other with the piston rod of oil cylinder is the active depression bar, the tooth bar that is arranged on the active depression bar is the active tooth bar, the gear that is meshed with the active tooth bar is a driving gear, the sprocket wheel coaxial with driving gear is drive sprocket, and remaining is respectively passive depression bar, passive tooth bar, driven gear and by movable sprocket.
Operation principle of the present invention is: hydraulic system drives oil cylinder, the piston rod of oil cylinder promotes initiatively depression bar, initiatively depression bar drives initiatively tooth bar, active rack drives driving gear, the rotation of driving gear causes the drive sprocket rotation, the transmission of passing through chain of drive sprocket drives by movable sprocket, make by the movable sprocket drive sprocket with the speed rotation, and and then pass motion to driven gear, passive tooth bar and passive depression bar, thereby finally make the power from oil cylinder pass to initiatively depression bar and passive depression bar synchronously, synchronize them and stretch and then clamp Taper Pipe synchronously.
Effect of the present invention is: 1. from operation principle of the present invention as can be seen, the present invention can guarantee that all depression bars clamp synchronously, thereby makes each side of Taper Pipe stressed evenly, guarantees the quality of Taper Pipe closing in weld seam.2. roller is equipped with in the end of depression bar, makes clamping force pass to Taper Pipe more equably by roller, has further guaranteed the quality of closing in weld seam.
