Abstract
The utility model relates to a pneumatic control mechanical roller head in the automobile welding production line, belonging to the field of machinery; the roller head is used for flanging pressing of door and cover assemblies and overcomes the disadvantages that the existing roller head can not be adaptive to the changeable rolling force completely and the product quality is hard to strictly guaranteed. The pneumatic control mechanical roller head comprises a connecting flange of the existing roller head, a connecting rod fixed on the flange, a roller wheel body at the end part of the connecting rod and a pressing wheel on the roller wheel body; the improvement is that: an air cylinder is arranged in an axial inner hole of the connecting rod, a joint is connected at the end part of a piston rod of the air cylinder, and a locating sleeve with a cone-shape axial hole is articulated on the joint; a buffering body and a locating shaft are additionally arranged between the connecting rod and the roller wheel body, and a pressure spring is arranged in a ring-shaped cavity between the buffering body and the locating shaft, and guiding plates at two sides of the buffering body form a pressure adjustment and buffering mechanism. The pneumatic control mechanical roller head has the beneficial effects that the pressure applied to a workpiece by the roller head is adaptive to the changeable rolling force, the adjusting difficulty of a robot procedure is reduced, the quality of the rolling product is ensured and the service life of a bottom die is improved.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to car body welding producing line and produces automobile door, the used pressing roller-head of cap assembly.
Background technology
Stitching wheel and roller body, roller body and connecting rod, connecting rod and adpting flange in the automobile door that uses on the existing auto production line, the cap assembly flanging pressing roller-head all are rigidly connected, difficulty was bigger when roller-head was adjusted program in robot, product quality is difficult for guaranteeing, the service life of also having reduced bed die simultaneously.In the mechanical damping formula roller-head that the applicant improves out, because the deformation force of spring is the increase along with distortion, deformation force increases.In actual rolling pressing process, pressure force is in pressing just and final pressure is fashionable that very big difference is arranged, so this roller-head can not be fully in real work adapt with the roll extrusion power of variation, and product quality still is difficult to obtain strict guarantee.
Summary of the invention
The purpose of this utility model provides a kind of automotive welding production line gas control mechanical type roller-head, be used for the flanging pressing of door, cap assembly, overcome roller-head and can not adapt with the roll extrusion power that changes fully in real work, product quality is difficult to obtain the deficiency of strict guarantee.
The utility model comprise existing roller-head adpting flange, be fixed on the flange upper connecting rod, be installed in the connecting rod end roller body, be installed in the stitching wheel on the roller body, the improvement of being done is near in the axial bore of flange one end cylinder to be installed at connecting rod, the piston rod end of cylinder is connected with the joint of hinge hole, is hinged with the positioning sleeve of taper axle center hole on the joint.Between connecting rod and roller body, increase the buffer body that is fixed on the connecting rod, buffer body vertically divides width different two parts, joining place forms step, there are two sections circular holes in the footpath that differs in size at the buffer body center, pass locating shaft at the buffer body centre bore, there is one section conical surface the locating shaft end of piercing in the connecting rod, and the conical surface partly stretches in the positioning sleeve.Locating shaft has ring protruding near end position, and locating shaft is having the protruding end of ring screw thread to be arranged, setting pressure spring in the annular chamber between buffer body and locating shaft.Be equipped with guide plate on the side of the both sides of buffer body thickness major part.Guide plate one side is fixed with the pressing plate with buffer body thickness smaller portions contacts side surfaces, and guide plate opposite side and roller body are fixedly connected.Roller body is through on the locating shaft and the lock nut by being assemblied in the location axle head and the ring on the locating shaft is protruding that roller body is clamped on the locating shaft.Have in corresponding spring end position and to pass the spring pressure guiding mechanism that the protruding screw of roller body and set collar and the backing plate that is contained in the pressure holding spring end constitute.
Operation principle of the present utility model: before roller-head used, rotation was adjusted nut and is adjusted initial tension of spring at first as requested, then the roller-head flange was connected with robot six shaft flanges.Using time device people drives the program roll extrusion workpiece of roller-head according to prior establishment.When workpiece need be used the roll extrusion of the less limit of pressure force, when surpassing, roll extrusion power preestablishes roll extrusion power, then spring generation deformation, roller body drives stitching wheel, the stitching wheel assembly moves to guarantee the roll extrusion quality to the robot direction along the locating shaft axis direction.If when workpiece need be used the roll extrusion of pressure force larger skirt, it is former in to increase the pressing pretightning force then to connect gas, adjusts gas pressure to adapt to the demand of different pressure forces, assurance roll extrusion quality according to the size of pressure force in the roll extrusion process.
Good effect of the present utility model is: set up the cylinder in connecting rod, can guarantee the demand of low pressure force of first pressing stage in the first pressing stage of rolling pressing; In the final pressure stage, satisfy the high requirement of final pressure stage pressure force, roller-head apply with workpiece on pressure and the roll extrusion power of variation adapt.Simultaneously, adjustable buffer gear is arranged between roller body and the connecting rod, reduce robot program's adjustment difficulty, guarantee the roll extrusion product quality, improve bed die service life.
