Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model patent is further detailed.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, large-caliber thin-walled cylinder docking assemble welding clamping device, comprise pad 3 in two groups of rigid external collar 1 and a combined type, often the group internal diameter of rigid external collar 1 and the external diameter of large-caliber thin-walled cylinder 4 match, often organize rigid external collar 1 to be connected to form by bolt 6 by least two group rigidity semi outer rings, the side often organizing rigid external collar 1 is provided with slope 9, the slope 9 of two groups of rigid external collar 1 is along the relative continuous distributed in weld seam both sides of large-caliber thin-walled cylinder 4, electromagnet 2 is fixed in rigid external collar 1 along weld seam both sides, in combined type pad 3 by some sections of arc plates 7 by being located at the pin-and-hole at arc plate 7 two ends and being provided with steady pin 8 head and the tail connecting successively the ring that the internal diameter that forms an external diameter and large-caliber thin-walled cylinder 4 matches in pin-and-hole, arc plate 7 is made up of the material with permeance and good rigidity.
Rigid external collar 1 is made up of the material of magnetic conductivity and good rigidly.
As the further improvement of the utility model patent, in combined type, pad 3 is provided with some magnetics, the power of attracting each other with the magnetic of rigid external collar 1 is provided, the strength that in rigid external collar 1 and combined type, pad 3 combines can be improved further, make to fix and position more reliable.
As the further improvement of the utility model patent, in combined type, pad 3 increase is configured with support roller.In combined type, pad 3 is configured in large-caliber thin-walled cylinder 4 junction and compresses large-caliber thin-walled cylinder 4 with rigid external collar 1 adhesive, and support roller is placed in outside rigidity, fits between 1 and the interior pad 3 of combined type with large-caliber thin-walled cylinder 4 junction.Act on the pressure of large-caliber thin-walled cylinder 4 junction when can bear assembling, the large-caliber thin-walled cylinder 4 reduced after assembling is out of shape.
As the further improvement of the utility model patent, the magnetic of rigid external collar 1 or the interior pad 3 of combined type is the adjustable electromagnet of magnetic, can according to the required power adjusting magnetic in real time of assembling.And the position of Internal and external cycle of being more convenient for adjusts and dismounting.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the magnetic line of force of electromagnet 2, through the aluminium alloy barrel of large-caliber thin-walled cylinder 4, pads 3 in strong adsorption combined type, forms the continuous support at the bottom of butt welding required by Friction stir welding.
In assembling process, align with the weld seam of large-caliber thin-walled cylinder 4 in rigidity inner ring 1 centre position, rigid external collar 1 distributes in weld seam bilateral symmetry, stay sufficient space can hold soldering tip 5 between both sides rigid external collar 1 movable, constantly adjusted in rigid external collar 1 and combined type by controlled electromagnet 2 and pad the position of 3 to ensure best frock.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model patent in use, first being inserted in respectively by several rigid external collar 1 that internal diameter mates with large-caliber thin-walled cylinder 4 external diameter treats on two sections of Butt Assembling large-caliber thin-walled cylinders 4, and treating joint and placing along joint both sides near large-caliber thin-walled cylinder 4, the slope 9 of rigid external collar 1 is towards large-caliber thin-walled cylinder 4 joint.Then the radially inner side that 3 are placed on rigid external collar 1 in large-caliber thin-walled cylinder 4 will be padded in combined type, guide in adjustable combination type to pad inside 3 and large-caliber thin-walled cylinder 4 by the polarity of the electromagnet 2 and rigid external collar 1 that are arranged on rigid external collar 1 both sides and post and fix, make two sections of large-caliber thin-walled cylinder 4 radial directions and be axially closely as one.Thus before further assembly manufacturing, eliminate large-caliber thin-walled cylinder 4 joint axial float and radial misalignments and distortion, and reliably support for providing during assembly manufacturing.After having assembled, first unload lower electromagnet 2, thus rigid external collar 1 and the interior pad 3 of combined type of lower device can be unloaded easily.
