The tension-pulling device thermally swells and pulls side enclosure skin of ultra-long passenger car through the acting force of a jack, and solves the problems that the quality of side enclosure skin is unstable because of inadequate swelling and pulling and uneven pulling.
Description
Technical field
The present invention relates to a kind of expansion pulling device of the solicit patrons car side wall skin that is used to rise.
Background technology
At present, in the manufacture process of motor bus, good manufacturing process is never found in side wall skin processing.Existing manufacturing process is flat through earlier roll bending being opened, after carry out fold shaping, rise through easy turnbuckle again and draw.Because characteristics such as the area of side wall skin is big, and length is long, and length direction gravitation is big; Turnbuckle is when drawing, and its position is difficult fixing, the difficult control of drawing direction; The drawing pressure skewness; Thereby cause the side wall skin local deformation uneven, the time generation of deficiency of drawing or partial failure phenomenon is arranged, steady quality is difficult to guarantee.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of pulling force that rises is strong, tension distribution is adjustable, the uniformity of drawing direction expansion pulling device preferably.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of expansion pulling device comprises: base, support and Drag link; This support comprises: upper and lower backstay that is parallel to each other and the connecting rod that connects upper and lower backstay; Following backstay links to each other with base, and described connecting rod is provided with at least two horizontal sliding mechanisms that cooperatively interact, and the push rod top of horizontal sliding mechanism links to each other with Drag link; Drag link is provided with at least two drag hooks, cooperatively interacts between the drag hook.
Described upper and lower backstay is respectively arranged with gathering sill in the left side of connecting rod, and the two ends of said Drag link are slidingly arranged in respectively in the gathering sill of a corresponding side.
Described upper and lower backstay is the hollow type structure, and its right-hand member is movably set with upper and lower location adjusting lever respectively, and can be between last location adjusting lever and last backstay, the positioning sleeve that cooperatively interacts of setting respectively between location adjusting lever and the following backstay down.
Four bights of said base are respectively arranged with a universal wheel.
The bottom surface of said down backstay is provided with that several are different in size, the support bar of hollow, and described base is provided with the cramp bar that matches with support bar, and cramp bar stretches in one of them support bar.
Described horizontal sliding mechanism is a jack.
Described jack is a hydraulic jack.
The invention has the beneficial effects as follows: at least two jack that are installed on the connecting rod of the present invention; Make the pulling force that rises strong and steadily, carry out heat at workpiece such as side wall skin and rise when drawing, can workpiece be welded on the location-plate that offers the locating hole that matches with drag hook overlength; Drag hook links to each other with location-plate; The location of workpiece is very convenient, and the uniformity of drawing direction is better, and can come to adjust individually or simultaneously each jack as required; Make tension distribution adjustable, improved the quality of product greatly.In addition, upper and lower backstay can install upper and lower location adjusting rod respectively additional, and the cramp bar on the base can be located in the various supports bar, makes this expansion pulling device go for the processing of various passenger vehicle side wall skin; And be arranged on the universal wheel on the base, and greatly facilitate moving of this expansion pulling device, reduced labour intensity.
