Pressure shell and intermediate body full-automatic locating and assembling tool

Abstract

The invention discloses a pressure shell and intermediate body full-automatic locating and assembling tool. The pressure shell and intermediate body full-automatic locating and assembling tool comprises a base, a pressure shell locating mechanism and an intermediate body locating mechanism. The pressure shell locating mechanism is arranged on the base. The intermediate body locating mechanism comprises a guide mechanism, a first locating block, a second locating block and a first driving part. The guide mechanism is arranged on the base. The first locating block and the second locating block are connected with the guide mechanism and are connected through the first driving part. Through the arrangement, the full-automatic locating and assembling tool conducts locating through the pressureshell locating mechanism. The first locating block and the second locating block of the intermediate body locating mechanism move through the guide mechanism under the action of the first driving partand clamp an intermediate body, and then the intermediate body can be adjusted to the required angle to be assembled. Moreover, in the process of tightening bolts, the first driving part can make theintermediate body bear clamping force continuously. The full-automatic locating and assembling tool ensures that the intermediate body cannot rotate during bolt tightening, and guarantees the installation quality.

Description

technical field [0001] The invention relates to the technical field of turbocharger assembly, in particular to a full-automatic positioning assembly tool for a pressure shell and an intermediate body. Background technique [0002] Turbocharger products are widely used in automobile engines and as the core components of the engine. The operating conditions are long-term under ultra-high speed, high pressure and high speed, and it is accompanied by ultra-frequency vibration of the engine. stricter assembly quality requirements. Such as the strength of the product after assembly, the installation angle with the engine, the selection of the boundary connection method, etc., thus putting forward requirements for process stability, strong error-proof ability and reliability of tooling design. [0003] The existing method of positioning and assembling the pressure shell and the intermediate body is fully manual operation and assembly. First, the pressure shell and the intermediate...

Problems solved by technology

[0003] The existing method of positioning and assembling the pressure shell and the intermediate body is fully manual operation and assembly. First, the pressure shell and the intermediate body are pre-assembled, and the bolts are pre-tightened, and then the pre-assembled pressure shell and the intermediate body are manually assembled. Put the intermediate body into the tooling, and manually move the positioning mechanism, lock the bolts after clamping, and then tighten the bolts. However, during the tightening process, even if the positioning mechanism has been locked, there may still be Slight rotation leads to unstable angle, and since the pressure shell is made of aluminum, and the positioning mechanism in contact with it is made of nylon material, slight rotation will cause wear and tear of the positioning mechanism during long-term use, which will lead to inaccurate positioning
