Automatic precision turning machine for heavy truck gearbox assembly

Abstract

The invention relates to the field of heavy truck speed changing box assembling, in particular to an automatic accurate overturning machine for heavy truck speed changing box assembling. The automatic accurate overturning machine comprises a machine body, a clamping lifting mechanism, an overturning clamping claw, a clamp clamping claw, a positioning lifting mechanism, a positioning rotating mechanism and a positioning bearing disc. The clamping lifting mechanism is arranged on a first support of the machine body. The overturning clamping claw and the clamp clamping claw are arranged on the clamping lifting mechanism. A workpiece is movably clamped through the overturning clamping claw and the clamp clamping claw, and after the workpiece is clamped, overturning is conducted through the overturning clamping claw. The positioning lifting mechanism is arranged on a second support of the machine body and provided with the positioning rotating mechanism, the positioning rotating mechanism is provided with the positioning bearing disc, the positioning bearing disc is driven to rotate through the positioning rotating mechanism, a tray bearing the workpiece is supported and positioned through the positioning bearing disc, and a machine body base between the first support and the second support is provided with a floating bearing. The automatic accurate overturning machine can automatically overturn a heavy truck speed changing box shell assembly, and the precision positioning requirement is met after overturning.

Description

technical field [0001] The invention relates to the field of heavy truck gearbox assembly, in particular to an automatic and precise turning machine for heavy truck gearbox assembly. Background technique [0002] In the process of assembling heavy truck gearboxes, the assembly of the gearbox housing assembly is a very important part. In the assembly process of the gearbox housing assembly, it is necessary to assemble multiple different joint surfaces of the housing. Due to the heavy truck gearbox housing assembly is heavy and bulky, it is difficult to turn over automatically. At the same time, for the assembly of the online station It is necessary to precisely position the housing on the pallet after turning over, which increases the difficulty of assembling the heavy truck gearbox housing assembly. Because it is difficult to turn over and accurately locate the heavy-duty transmission housing during the assembly process, the logistics of the heavy-duty transmission assembly...

Problems solved by technology

In the assembly process of the gearbox housing assembly, it is necessary to assemble multiple different joint surfaces of the housing. Due to the heavy truck gearbox housing assembly is heavy and bulky, it is difficult to turn over automatically. At the same time, for the assembly of the online station It is necessary to precisely position the housing on the pallet after turning it over, which increases the difficulty of assembling the heavy truck gearbox housing assembly

Because it is difficult to turn over and accurately locate the heavy-duty transmission housing during the assembly process, the logistics of the heavy-duty transmission assembly line in the prior art mostly adopts the form of AGV / RGV trolleys, but this logistics form can only be assembled manually and cannot be used online. Automatic assembly equipment for assembly, which seriously restricts the development of automatic online assembly of heavy truck gearboxes
