Welding mould of top frame of passenger car

Abstract

The invention discloses a welding mould of a top frame of a passenger car, which is capable of being simultaneously suitable for multiple serial vehicle types with different dimensions. The welding mould of the top frame of the passenger car comprises a mould base, a plurality of horizontal guide rails which correspond to horizontal beams and horizontal partition beams of the top frame and are adjustable in left and right positions are arranged on the mould base, wherein the horizontal beams and the horizontal partition beams of the top frame need to be supported; at least one pair of horizontal beam brackets being adjustable in both front and rear positions and heights are arranged on the horizontal guide rails, and longitudinal beam brackets which correspond to longitudinal beams and longitudinal partition beams of the top frame, are adjustable in both the front and rear positions and the heights and can avoid the horizontal beams are also arranged on the horizontal guide rails corresponding to the horizontal beams, wherein the longitudinal beams and the longitudinal partition beams of the top frame need to be supported; and at least one pair of top edge beam brackets which are matched with top edge beams positioned at a corresponding side and adjustable in the front and rear positions and at least one pair of top edge beam jigs locking the top edge beams positioned at the corresponding side are respectively arranged at the front side and the rear side of the mould base. As for the serial vehicle types, the welding mould realizes the universalization, and a special welding mould is unnecessary to provide for each extended vehicle types, and therefore, the production and manufacture cost is greatly saved.

Description

technical field [0001] The invention relates to a welding mold, in particular to a welding mold of a passenger car roof frame. Background technique [0002] Everyone in the industry knows that the bus manufacturing industry has a notable feature: during product development, the basic model is first designed, and after the passenger car is sold to the market and approved, in order to meet market demand, the basic model is expanded by changing parameters such as the size of the bus body , forming serialized products. After the size of the passenger car body changes, the size of its top frame changes, so that the mold for welding the top frame also needs to be adjusted. The specific structure of the current mold for welding the top frame includes: a mold seat and a beam seat arranged on the mold seat to match the beam and the transverse partition beam, and the longitudinal beam seat matched to the longitudinal beam and the longitudinal partition beam And the top edge beam sea...

AI Technical Summary

Problems solved by technology

For a bus manufacturing enterprise, this not only increases the manufacturing cost, but also brings unnecessary troubles due to frequent replacement of welding molds, which affects the production cycle; at the same time, a large number of welding molds occupy the production site , which affects the utilization rate of the production site and increases the manufacturing cost
