Utility model content
The technical problems to be solved in the utility model be to provide a kind of Stability Analysis of Structures, reliable, be convenient to weld the rotation of weldering tire, the detent mechanism of tire rotation.
For solving the problems of the technologies described above, the rotation of weldering tire, the detent mechanism that provide comprise underframe, its design feature is: the two stands being longitudinally oppositely arranged is housed on underframe, on the support of front side, be rotatably connected to driving shaft, on driving shaft, be connected with rotation hand wheel, on driving shaft, be also equipped with the brake gear of driving shaft location, be rotatably connected to the driven shaft being oppositely arranged with driving shaft on the support of rear side, on driving shaft and driven shaft, correspondence is equipped with weldering tire holder.
Described brake gear comprises bracket arm, one end of bracket arm is hinged on underframe, the other end is provided with pedal, on bracket arm, be connected with the push rod of stretching, on described driving shaft, be connected with brake disc, the circumference side of brake disc is provided with the multiple breach that coordinate with push rod top, between the middle part of bracket arm and support, extension spring is housed.
Described weldering tire holder comprises gripper shoe, and in the gripper shoe of two correspondences, upper and lower correspondence is equipped with supporting base respectively, and on upper and lower two corresponding supporting bases, correspondence is provided with bolt mounting hole.
Underframe is provided with levelling device.
Described levelling device comprises the leveling board that is fixed in respectively underframe four bights, is at least bolted with two leveling bolts on each leveling board.
Adopt after said structure, welding positioner is connected between the two corresponding weldering tire holders that arrange, drive driving shaft rotate and by brake gear, driving shaft located by rotation hand wheel, thereby realize accurately the rotation of welding positioner, thereby the body in white completing on butt welding tire carries out multi-direction welding.The brake gear arranging can guarantee the rotational angle of driving shaft, guaranteed the rotational angle of welding positioner, thereby facilitate the welding of workman to body in white, and can guarantee the rotational stabilization of welding positioner, thereby provide good basis for the welding of body in white.Welding operation is flexible, guarantees that fixture production has enough welding equipment spaces, makes operating personnel have the good visual field and operating environment, makes the overall process of welding production in stable duty.
In sum, this mechanism's manufacture, installation, easy to operate.Adopt hand wheel rotating to drive weldering tire rotation, reduce fixture manufacturing cost, this mechanism has advantages of that compact conformation, reliable operation life-span are long, makes this structure more stable.
