Description
Technical field
The invention belongs to the group of rail vehicle riser section weldering positioning auxiliary device field, and in particular to a kind of riser is with small
Angle is from folding clamping and positioning frock.
Background technology
The mechanisms such as the framework of trolley coach largely use the cross section formed by the weldering of multi-sheets splicing group as the whole of box
The big part of body, under many specific process design considerations, the production order of this part of base part is that first vertical registration is placed
Riser, ultimately form upper and lower end face welded cover plate from the big modular construction of required box to riser or bottom plate again afterwards.
Compared to for the common process that riser is positioned to spot welding on fixed horizonal base plate, take the lead in vertical registration riser
Special operation technique then has more complexity, its vertical posture for needing not only to ensure riser but also needs to ensure riser in the horizontal plane
Direction and position, then can just come into effect welding.Conventional riser for such technique positions instrument, typically prefabricated
Locating groove, cover horizontal or vertical clamp more, set is horizontal more or vertical leading screw class auxiliary locating tool equipment, so as to respectively from riser
Both sides and upper end are implemented multipoint clamping and are accurately positioned to it respectively.
However, prefabricated locating groove pilot pin can be only applied to the sheet material positioning of given width, the sheet material of different in width
The neck frock of prefabricated a variety of different in width is needed, and horizontal or vertical clamp, level or vertical leading screw class positioning tool etc. are auxiliary
Positioning tool is helped to need each other in using, cooperation reversely with each other, it is when riser workpiece height changes or be longer, it is necessary to very greatly
Layout quantity, and need to adjust positioning posture one by one, it is cumbersome, it is difficult to fast positioning and unblock to be realized, so that shadow
The raising of production efficiency is rung, and is unfavorable for stock control of classifying.
The content of the invention
The level used in pairs is covered in order to solve the special operation technique generally use of the existing vertical registration riser that takes the lead in more
Or the auxiliary locating tool equipment such as vertical clamp, level or vertical leading screw class positioning tool is used cooperatively, its be laid out quantity big, positioning and
Unblock efficiency it is low, it is cumbersome and be unfavorable for classify stock control；And the riser of the neck frock of prefabricated a variety of different in width is determined
Position method poor universality, is unfavorable for saving the technical problem of production cost, and the present invention provides a kind of riser low-angle from folding
Clamping and positioning frock.
