Chassis assembly tooling

Abstract

The invention provides an assembling tool for an enclosure. The assembling tool comprises a framework, outer casing supporting and fixing assemblies, an inner casing supporting and fixing assembly and a connecting plate supporting assembly, wherein the framework is used for providing support; each outer casing supporting and fixing assembly comprises a base plate, a first pressing plate and a first pressing plate supporting seat; each base plate is fixedly arranged at the upper part of the framework; each first pressing plate supporting seat is fixedly arranged at the upper part of the corresponding base plate; each first pressing plate is fixedly arranged on the corresponding first pressing plate supporting seat in a moving manner so as to press an outer casing base plate of the enclosure; the inner casing supporting and fixing assembly comprises a center shaft, a second pressing plate and a locking part; the center shaft is fixedly arranged on the base plate and is used for supporting an inner casing base plate of the enclosure; the second pressing plate and the center shaft are fixed by the locking part so as to clamp the inner casing base plate of the enclosure; the connecting plate supporting assembly comprises three baffles which are distributed at intervals by 120 degrees; the baffles are vertically arranged and are fixed on the base plate. According to the assembling tool for the enclosure, which is provided by the invention, the structure is simple; in addition, the supporting and the positioning for all parts of the enclosure can be accurately realized, so that the assembling precision of the enclosure before welding can be ensured and further the precision of the enclosure after welding is ensured.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a pair of tooling for a casing group. Background technique [0002] The fan used in the railway machinery industry is provided with a casing part, the casing is a rotary cylindrical part, the casing includes an outer shell, the outer shell is an arc-shaped rotary type part, and an inner shell that is not in contact with the bottom plate is provided in the middle of the outer shell through a connecting plate. The bottom plates of the outer shell and the inner shell are provided with through holes. The number of connecting plates is three, and they are evenly distributed at 120° intervals. [0003] The casing is a welded structure, and in the prior art, the welding accuracy is difficult to meet the drawing size requirements by manual welding. SUMMARY OF THE INVENTION [0004] The invention provides a pairing tool for a casing assembly, which is used for improving the welding efficiency ...
