Description
Technical field
The present invention relates to a kind of anchor clamps, after veneer reeling machine is rolled into, the heal up anchor clamps of usefulness of especially a kind of cylindrical shell.
Background technology
Cylindrical metal member (abbreviation cylindrical shell) uses very extensive in factory, as metal flue, alloy housing etc.Cylindrical shell is cylindrical, is to roll the back docking port by veneer reeling machine to weld and constitute.In rolling the docking operation of healing up, because equipment and factor such as artificial are difficult to once accurately heal up butt joint, common situation is to heal up to have just error, lower deviation on the interface.General method of adjustment commonly used is to beat or progressively adjust with instruments such as ripping bars with iron hammer, after first spot welding is in place, and continuous welding again.The shortcoming of above-mentioned method of adjustment is: cause the cylindrical shell part uneven easily, the groove gap size differs, and the melting welding infiltration is inconsistent, and generation easy to manufacture is leaked for pressure vessel like this, therefore influences the quality of cylindrical shell.Exist simultaneously and adjust trouble, reduced production efficiency.
Summary of the invention
Purpose of the present invention solves cylindrical shell production exactly when rolling back welding adjustment, exists cylindrical shell of poor quality, adjusts difficulty and reaches the low problem of production efficiency greatly.
The technical solution used in the present invention is: barrel close mouth fixture, it comprises L-shaped left socle, and the right support that is rotationally connected of left socle one end and be connected in the screw body that heals up that promotes the two stands folding between the two stands, and left socle and right support center are axial hole; The described screw body that heals up comprise two terminal filament tooth rotation directions opposite heal up screw mandrel and with left-handed nut and the right-handed nut of the adaptive formation screw body of screw mandrel two terminal filament teeth that heals up, left-handed nut and right-handed nut lay respectively in the axial hole of left socle and right support, left socle and right support correspondence position are respectively equipped with radial hole, be respectively equipped with the rotating shaft adaptive with radial hole on left-handed nut and the right-handed nut, rotating shaft is positioned at radial hole, makes left-handed nut and right-handed nut to rotate in radial hole; The other end of left socle and right support is respectively equipped with jaw, and the sidewall of jaw is provided with screw, is provided with the trip bolt that cooperates with it in the screw.
Adopt technique scheme, when cylindrical shell rolls the back butt joint, the both sides of cylindrical shell cooperating by trip bolt and jaw, be separately fixed on left socle and the right support, by the rotation screw mandrel that heals up, because the silk tooth is opposite, nut is executed on a left side and the right-handed nut will be close mutually, make left socle and right support close mutually, thereby the both sides that drive cylindrical shell are close mutually, finally reach the adjustment requirement of welding.
For being staggered, the cylindrical shell both sides also can adjust, it also comprises just adjusts screw body, this mechanism is positioned at an end of right support, it comprises that two ends are provided with the opposite vertical screw mandrel of a tooth rotation direction, vertically the screw mandrel two ends are provided with adaptive with it top nut and lower nut, top nut and lower nut lay respectively in the axial hole of left socle and right support end, left socle and right support end correspondence are provided with through hole, top nut and lower nut are provided with turning cylinder, turning cylinder is positioned at through hole, makes top nut and lower nut to rotate in through hole.
Stagger needs when adjusting when the cylindrical shell both sides, rotate vertical screw mandrel, top nut and lower nut will be mutually near or away from, make be clipped in left and right support upper shell both sides mutually near or away from, reach the purpose of adjustment.
In sum, the invention has the beneficial effects as follows: because the present invention can reach cylindrical shell both sides upper-lower position and adjust and the adjustment of position, the left and right sides, so the present invention be easy to adjust, has improved production efficiency by screw mandrel and the vertically screw mandrel rotation of healing up.Because the present invention makes the cylindrical shell both sides can realize accurate adjustment, so during the cylindrical shell welding, the quality height.
