Again because the rectification wheel shaft is the rotation realization rectification wheel of eccentric shaft, employing eccentric shaft and the big or small adjustment of spacing between drive sprocket axle.Can only enter rectification " chamber " before at workpiece, mix up the height of correcting between wheel and drive sprocket axle after, eccentric shaft is locked.Adjustment is got up cumbersome, and need adjust several times and just can achieve the goal, and often because workpiece is different different with welding procedure, the workpiece fashion of correcting, the time bad, correction quality control must rely on experienced operative employee to finish, and not only is difficult to operation and correction quality instability.
In addition, adopt this structure to correct wheel and must mix up the position before welding, the steel plate that is to say upwards distortion must be extruded into firmly to correct and go below the wheel, may hit sometimes and correct on the wheel, causes that to correct the wheel inner bearing stressed excessive and damage.
Summary of the invention
The problem to be solved in the present invention provides a kind of straightening mechanism.Adopt this straightening mechanism, not only the scope of application is unrestricted, and the damage of being convenient to operate, improving correction quality, avoid correcting the wheel inner bearing.
For addressing the above problem, take following technical scheme:
Straightening mechanism of the present invention comprises base, and two frames are arranged on the base, between two frames driving wheel is arranged, and is rotatable shape between the equal wheeled base in driving wheel both sides, drive sprocket axle and wheel seat and cooperates.After having motor, drive sprocket axle one end to pass a frame, the frame outside links to each other with the output shaft of motor.Be characterized in that described frame is the U-shaped frame, this two frame all is the inversion type positioned opposite.Elevating bracket is all arranged in two frames, and this two elevating bracket and corresponding frame two are erected all to be between walls and are slidingly matched.Axis hole is all arranged on two elevating brackets, wheel shaft is all arranged in the axis hole, be rotatable shape by bearing between wheel shaft and axis hole and cooperate.Two axles is coaxial, and their neighboring terminal all stretches out outside axis hole and is fixed with corrects wheel.Frame top all has oil cylinder, and the piston rod of this two oil cylinder all also is connected with corresponding elevating bracket respectively mutually towards the below.
Take such scheme, have the following advantages:
By such scheme as can be known, described frame is the U-shaped frame, and this shape frame all is the inversion type positioned opposite.Elevating bracket is all arranged in two frames, and this two elevating bracket and corresponding frame two are erected all to be between walls and are slidingly matched.Axis hole is all arranged on two elevating brackets, wheel shaft is all arranged in the axis hole, be rotatable shape by bearing between wheel shaft and axis hole and cooperate.Two axles is coaxial, and their neighboring terminal all stretches out outside axis hole and is fixed with corrects wheel.Frame top all has oil cylinder, and the piston rod of this two oil cylinder all also is connected with corresponding elevating bracket respectively mutually towards the below.
Adopt oil cylinder as actuating unit, the spacing size between rectification wheel and drive sprocket axle presses down by oil cylinder drive elevating bracket and realizes.And the rectification wheel does not have bearing and is with rectification wheel between centers fixedlys connected, and makes the rectification wheel can do greatly, and it is big to correct wheel one, and bearing capacity is just big.Therefore, straightening mechanism of the present invention both had been applicable to be corrected the H shaped steel of reduced size, can be used for correcting the H shaped steel of large-size again, and the scope of application is not restricted.
Again because the spacing size of correcting between wheel and drive sprocket axle adopts oil cylinder to adjust.Can enter rectification " chamber " at workpiece presses down afterwards again, corrects, and the spacing of correcting between wheel and drive sprocket axle can be adjusted at any time, and adjustment is got up more convenient, and correction quality control replaces traditional operative employee to finish by oil cylinder, not only be convenient to operation, and correction quality is stable.
