Description
Technical Field
The utility model belongs to the technical field of the welding technique and specifically relates to a cylindrical welding piece axial float adjustment system on welding gyro wheel frame is related to.
Background
The welding roller frame is provided with four rollers for supporting a cylindrical weldment, the central axes of the four rollers are on the same plane and are parallel to each other theoretically, the distance between the two rollers at one end of the weldment is equal to the distance between the two rollers at the other end of the weldment, and the axis of each roller is parallel to the central line of the weldment. However, due to manufacturing and installation accuracy and other reasons, the roller axis and the central axis of the weldment are not parallel to form a helical angle, so that the weldment moves axially.
The conventional welding roller frame for preventing axial movement mainly comprises a driving roller (for driving a weldment to rotate), a driven roller frame (for adjusting the axial movement direction of the weldment), a weldment axial movement detection device and a control system. The axial movement detection device of the weldment mainly props against the end face of the weldment through a spring force by a sensor so as to move along with the axial movement of the weldment. According to the magnitude and direction of the axial movement displacement and speed, the axial movement displacement and speed are fed back to the control system, and the anti-movement mechanical actuating mechanism acts to achieve the anti-movement purpose. The anti-channeling mechanical actuating mechanism comprises three types, namely a deflection type actuating mechanism, a jacking type actuating mechanism and a translation type actuating mechanism, wherein the translation type actuating mechanism is commonly used, a driven roller horizontally moves along the central axis of a weldment in a direction perpendicular to the central axis of the weldment, the axial movement direction of the weldment is adjusted, and the anti-channeling function is realized.
But the welding roller frame for preventing axial movement at present has the following problems: the detection mode commonly used at present is the detection of the end face of a cylindrical weldment, and the mode is inevitably influenced by the unevenness of the end face of the weldment in the vertical direction of the end face and the axial lead of the weldment, so that the requirement on the end face precision is high; at present, a translation type actuating mechanism is commonly used for adjusting a driven roller to horizontally move along a central axis of a weldment in a vertical mode to realize a channeling-prevention function, the horizontal movement of the driven roller is determined by forward and reverse rotation of a motor, but the rotating speed of the motor is a limited constant value, time is needed for translation of the driven roller and turning of a helical angle of the weldment, and if the motor does not act in time, shaft channeling displacement exceeds an allowable range; in order to ensure that the shaft shift is controlled within an allowable range within a specified time, the control is realized by adopting a nonlinear control law of displacement and speed negative feedback on a computer or a PLC (programmable logic controller) through theories of fuzzy control, adaptive control and the like, and a control system is complex; finally, the condition of the current domestic existing process determines that the deviation between the shape of the weldment and the theoretical shape is larger, namely the error ratio of roundness and cylindricity is larger, so that the amplitude and the randomness of axial movement of the weldment when rotating on the roller carrier are increased. Based on the problems, although a plurality of barrel weldment manufacturers need to weld the anti-channeling roller frame, the anti-channeling function is still finished by an operator looking at hand adjustment, and the automatic anti-channeling function is just one decoration.
To above problem, the utility model relates to a cylindric weldment axial float adjustment system on welding roller carrier realizes the timely translation of driven roller carrier, avoids axle float displacement to surpass the allowed range, reduces the requirement for precision of butt weld detection face simultaneously.
