Description
Technical field
The present invention relates to a kind of positioning tool and welder, especially relate to a kind of tower top of tower crane upper bracket upper bracket
Otic placode positioning tool and welder, it belongs to derrick crane field.
Background technology
Derrick crane abbreviation tower crane, tower top is arranged on upper bracket it is ensured that derrick crane raising when steel wire rope
Discharge and shrink stable, upper bracket is be combined with each other by pivoting support with undersetting, and this is heavy to carry tower crane rotation
Want function, be the centre of tower crane.
At present, when welding otic placode on upper bracket, the feeding of otic placode mainly passes through to join to be soldered into, the same upper bracket to tower top
Taking one-to-one principle, during to welding otic placode on each upper bracket, will lift to above upper bracket with the tower top that it matches, people
Work centering, manual feeding, and in upper manual clamping, positioning, then unloaded using manual point postwelding and carry out artificial full weld again, or
Directly automatically carry out the welding manner of full weld.
The welding of the otic placode of existing upper bracket relies on to join and is soldered into, and its positioning relies primarily on the technical merit of workman to ensure
Product Precision, and organize the spacing between the end face plane degree of otic placode, adjacent sets otic placode by the making precision of the tower top joining weldering, assembling
Precision and welding deformation state three together decide on.
Because tower top manufacture is uneven, workman's technical merit differs, and the body structure of upper bracket is due to welding change simultaneously
Shape whole height differs it is impossible to make compensation to welding deformation, can lead to increasing uncontrollable systematic error, will result in
Upper bracket cannot be realized exchanging with tower top, when otic placode being carried out with positioning clamping and welding, takes artificial loading, clamping operation,
And formerly point postwelding unloads in the mode carrying out artificial full weld more manually, low production efficiency, personnel labor intensity is high, artificial behaviour
The secondary welding made also increases welding deformation and error, and the welding precision ultimately resulting in otic placode is not high, simultaneously manual positioning, dress
Folder is also the factor of restriction Automation of Welding.
