By push-and-pull subpackage platen in described step (6), it is achieved the loading and unloading of the complete assembly of subpackage.
Panel sub-assembling platform in described step (1) includes subpackage platen, two bracers and positioning clamping devices；Wherein, described panel sub-assembling platform plate is with slide rail.
Press-loading apparatus in described step (4) includes two support bars, connecting plate and Fitted Axles, and described connecting plate is for connecting two support bars；Wherein, described support bar is with reinforcement.
A kind of heavy-duty car leaf spring pin press-loading device, guides and press-loading apparatus including panel sub-assembling platform, hydraulic cylinder, dust cover, leaf spring pin, and wherein, described panel sub-assembling platform includes subpackage platen, two bracers and positioning clamping devices；Described press-loading apparatus includes two support bars, connecting plate and Fitted Axles.
Described panel sub-assembling platform plate is with slide rail, and described support bar is with reinforcement.
The invention has the beneficial effects as follows:
(1) labor intensity and efficiency of assembling aspect: according to traditional leaf spring pin assembly technology, operator frequently uses copper hammer assembling, and labor intensity is big, and efficiency is low, needs about 4 minutes from product piece of taking to completing assembling leaf spring pin；The assembling of leaf springs of car pin uses press-fit approach then to use copper hammer to assemble without operator, only need to operate press-loading apparatus to press-fit, greatly reduce labor intensity, after using press-loading process, only need about 2 minutes to completing assembling leaf spring pin from product piece of taking, save installation time；
(2) assembling quality aspect: traditional leaf spring pin assembly technology, during operator assembles leaf spring pin, easily causes pad to loosen skew deformation, causes leaf spring the pin not in place or clamping screw of assembling cannot install and put in place, brings and reprocess waste；Use after press-fit approach, can be with precise positioning, it is ensured that assembling quality, it is to avoid waste；
(3) present aspect is become: traditional assembling mode copper hammer is lost quickly, in addition it is also necessary to increase protective eye lens and be used for protecting, prevent copper scale from splashing；After using novel press-fit approach, it is only necessary to normally press-loading apparatus is maintained, save the expense of copper hammer and protective eye lens, greatly reduce cost.
