Described rotary support seat comprises base and rotating shaft;
Described loading trolley positioner skeleton is rectangular structure;
The quantity of described loading trolley clamping device is 4 groups, is symmetricly set on four jiaos of loading trolley positioner skeleton top;
The quantity of described side wheel positioning support is 4, is symmetricly set on the bottom of loading trolley positioner skeleton;
The quantity of described loading trolley wheel alignment axle is 4;
The quantity of described pulley locating shaft is 2.
The beneficial effects of the utility model are:
(1) because the distance between two locators of loading trolley clamping device can regulate by the screw rod on locator, locator bottom is provided with bearing pin, locator can rotate around bearing pin, is therefore applicable to assembling and the welding of the loading trolley supporting leg of different model and length dimension;
(2) adopt tool locating accurately, during with original welding, compared with coarse positioning, improved positional accuracy, ensured the dimensional accuracy between the each parts of dolly;
(3) reduce debugging time of original coarse positioning, improved greatly production efficiency;
(4) workman can be chosen in more comfortable position welding in the time of welding, and deflection welding can rotate to realize by frock too simultaneously, has alleviated workman's labour intensity.
