Multi-model body-in-white welding general assembly fixture

Abstract

The invention provides a multi-type vehicle body in white welding main combined fixture. The multi-type vehicle body in white welding main combined fixture comprises a positioning device, wherein the positioning device is used for supporting a body in white and comprises a plurality of positioning bases; a side wall clamping device is arranged on two sides of the positioning device, and is moved towards or away from the positioning device through a translation mechanism which is arranged under the side wall clamping device; a rotary mechanism is arranged under the side wall clamping device and is used for adjusting the horizontal position of the side wall clamping device; each positioning base comprises a positioning assembly, a translation device and a height adjusting mechanism, each translation device is used for adjusting the horizontal position of the corresponding positioning assembly, and each height adjusting mechanism is used for adjusting the vertical position of the corresponding positioning assembly. The invention aims at providing the multi-type vehicle body in white welding main combined fixture, so that the multi-type vehicle body in white welding main combined fixture can be applied to multiple vehicle types.

Description

technical field [0001] The invention belongs to the technical field of body welding fixtures, in particular to a general combination fixture for multi-vehicle body-in-white welding. Background technique [0002] The development and introduction of new products for medium and heavy commercial vehicles is carried out in batches and year by year. At first, a standard single-cab medium-sized car was developed, and a standard single-cab body-in-white general assembly fixture and welding line were built accordingly. [0003] With the needs of long-distance logistics transportation, this standard single-row mid-sized car cannot meet the demand of the market, and it is necessary to add a row and a half model with a driver's rest. Later, the demand for long-distance freight and logistics increased further, and the vehicle type also developed from medium-sized vehicles to heavy-duty vehicles. [0004] In this way, there are body-in-white sizes of various models. In addition to the d...

AI Technical Summary

Problems solved by technology

[0005] The import price of the medium and heavy-duty body-in-white welding assembly fixtures is very high; secondly, because each model is invested step by step, it needs multiple outsourcing design, and there is a risk of outflow of body-in-white assembly body data. The survival of the enterprise is unfavorable; if a pair of general combination fixtures are designed for each model, the investment will be too high and the requirements for the site will be high
