Chain link is under the conveying of chain conveyor 1, slip over from the bottom plate mechanism 12 of chain link clamping device, through vertical location device 14 with after laterally levelling device 9 is aligned, the moving clamping hooks pawl mechanism 13 and clamps, enter the welding position, by the upper left locating piece of upper left clamp mechanism 4 controls, the lower-left locating piece that lower-left clamp mechanism 11 is controlled, the upper right locating piece of upper right clamp mechanism 7 controls and the positioner clamping chain link that bottom right locating piece 10 forms.The electrode heating apparatus that is comprised of left electrode clamping mechanism 5 and right electrode clamping mechanism 6 simultaneously clamps chain link, vertical location device 14 and bottom plate mechanism 12 returns.The electrode heating apparatus clamp chain hoop chain link that left electrode clamping mechanism 5 and right electrode clamping mechanism 6 form provides enough welding currents and chain link is heated.
Upsetting machine 8 is done to move back and forth fast, provides enough upset forces for chain link heals up.After the chain link welding finished, the electrode heating apparatus that left electrode clamping mechanism 5 and right electrode clamping mechanism 6 form unclamped.The moving clamping of chain link clamping device hooks pawl mechanism's 13 clamping welding chain links well, the upper left clamp mechanism 4 of positioner and lower-left clamp mechanism 11 returns, the burr that produces due to extruding on hydraulic pressure deburring device 2 excision chain girth joints.
After deburring is completed, the upper right clamp mechanism 7 of positioner moves upward and resets, the moving clamping of chain link clamping device hooks pawl mechanism 13 and unclamps, the lower-left clamp mechanism 11 of positioner moves up to that fixedly tire is concordant with the lower-left, the chain link that is unclamped by postwelding resets in company with the bottom plate mechanism 12 of chain link clamping device and leaves the welding position, pulled out left anvil iron 77 and right anvil iron 86 in bottom plate mechanism 12 by chain conveyor 1, complete the welding of chain link.Simultaneously another horizontal chain link is through laterally levelling device 9 levelling, moving clamp to hook enter position to be welded after pawl mechanism 13 clamps and carry out next operation cycle.
The fully automatic hydraulic chain link butt welding machine that the utility model provides comprises: frame 3; Be used for the electrode heating apparatus to the chain link heating, the electrode of this electrode heating apparatus is slidably mounted on frame 3 along Z-direction; Two both sides that are used for 1, two chain conveyor 1 of chain conveyor that horizontal chain link is carried toward the downstream one by one is installed on electrode heating apparatus, and each chain conveyor 1 all has angle with Y-axis; Be used for to clamp chain link uncovered to the position and chain link is delivered to the chain link clamping device of heating location, the chain link clamping device is slidably mounted on frame 3 along Y-axis; Be used for the chain ring position is fixed in the positioner of heating location, positioner is installed on frame 3; Be used for the uncovered upsetting machine that heals up 8 with the chain link of heating, upsetting machine 8 is slidably mounted on frame 3 along X-axis.What this fully automatic hydraulic chain link butt welding machine adopted is all-hydraulic technology, has avoided the cam upset to depend on the accuracy of manufacture of cam curve, has guaranteed the quality of welding chain link.The automation of welding burr and chain conveying is removed in realization with station, reduced labour intensity.The work of each operation of the machine is controlled by PLC, automatic selection, adjusting process parameter, coordinate the work of complete machine, realized the design of electromechanical integration, improved operating efficiency, simultaneously, this fully automatic hydraulic flash butt welder has reached that volume is little, compact conformation and can adapt to the chain link welding of different size and different situations, has reached each chain link open-mouth welding autocontrol after the chaining and has completed effect with welding quality stable.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
