Abstract
The present invention relates to an installation control method of multi-arc battens of monorail vehicle end wall, and comprises regulating the position error of two layers of frameworks with a square ruler as the benchmark. When the radius error of the arc of the framework is regulated, a sample plate with the same shape as the framework is designed and manufactured; the error is repeatedly regulated with the sample plate as the benchmark; after the framework is adhered to a pallet, a sample plate with the same shape as the framework adhered to the pallet is designed and manufactured; the square ruler and the sample plate are used as the benchmark; the pallet is trimmed and ground so as to regulate the position of the framework and the radius of the arc; a sample plate with the same shape as the battens is designed and manufactured, and is used as the benchmark to regulate the battens; the qualified battens is arranged on the qualified framework. The control method improves the manufacturing accuracy of the framework, further regulates the framework, and improves the manufacturing accuracy of the aluminum framework. The control method also solves the following problems: the arc of the battens does not match the arc of the aluminum framework; the flange of the battens can not cover the end wall plate; and the interface of each batten is not flat and even.
Description
Technical field
The invention belongs to trolley coach manufacturing technology field, especially relate to a kind of installation and control method of many circular arcs of gyrocar headwall press strip.
Background technology
At present, the gyrocar headwall is made up of two-layer aluminium skeleton, and there are seven sections circular arcs on the doorway of every layer of skeleton, at the circular arc periphery dihedral press strip is installed.Because the distortion in the welding process, the two-layer skeleton welding back opposite position on doorway is not or not same plane, and seven sections circular arcs of every layer of skeleton also deform; Simultaneously, the aluminium section bar press strip circular arc of simmering and bending is also inaccurate, and therefore, the circular arc of the circular arc of press strip and aluminium skeleton is misfitted, and press strip flange lid is end wall panel incessantly, and every section press strip interface injustice is uneven.
Summary of the invention
Technical matters to be solved by this invention provides a kind of installation and control method of many circular arcs of gyrocar headwall press strip, this method improves the skeleton accuracy of manufacture, improve the accuracy of manufacture of aluminium section bar press strip, the circular arc that solves press strip is misfitted with the circular arc of aluminium skeleton and press strip flange lid incessantly end wall panel and every section uneven problem of press strip interface injustice.
For solving the problems of the technologies described above, the invention provides a kind of installation and control method of many circular arcs of gyrocar headwall press strip, it is characterized in that comprising the following steps:
1. in the car body workshop, during the positional error of the two-layer skeleton of adjusting, be benchmark with the square; During the arc radius error of adjusting skeleton, designing and producing and the on all four model of skeleton size shape, is that benchmark carries out adjusting repeatedly with the model; At fitter's shop, after skeleton is pasted backing plate, design and produce with bonding backing plate after the on all four model of skeleton size shape, be benchmark with square and model, by the reconditioning backing plate, further frame position, arc radius are adjusted;
2. at the press strip workshop, designing and producing and the on all four model of press strip size shape, is benchmark adjusting press strip with the model;
3. the up-to-standard press strip of adjusting is installed on the up-to-standard skeleton of adjusting.
Advantage of the present invention is: increase aluminum alloy framework adjusting detection means, improve the skeleton accuracy of manufacture; Reconditioning detection means behind the bonding backing plate of increase skeleton is further adjusted skeleton; Improve the accuracy of manufacture of aluminium section bar press strip; The circular arc that solves press strip is misfitted with the circular arc of aluminium skeleton and press strip flange lid incessantly end wall panel and every section uneven problem of press strip interface injustice.
The specific embodiment
Embodiment
In the car body workshop, during the positional error of the two-layer skeleton of adjusting, be benchmark with the square; During the arc radius error of adjusting skeleton, designing and producing and the on all four model of skeleton size shape, is that benchmark carries out adjusting repeatedly with the model; At fitter's shop, after skeleton is pasted backing plate, design and produce with bonding backing plate after the on all four model of skeleton size shape, be benchmark with square and model, by the reconditioning backing plate, further frame position, arc radius are adjusted;
At the press strip workshop, design and produce and the on all four model of press strip size shape, with the model benchmark adjusting press strip;
The up-to-standard press strip of adjusting is installed on the up-to-standard skeleton of adjusting.
