Manufacture process of carbon fiber simulation block for automobile main model inspection tool

Abstract

The invention discloses a process for manufacturing a carbon fiber simulated block of an automobile master model checking fixture. The process is characterized by comprising the following steps: 1, designing a forming mold, namely designing a mold according to functions and technical requirements of the simulated block, and manufacturing the mold by using resin; 2, forming a carbon fiber framework, namely manufacturing the carbon fiber framework, and manufacturing a simulated bock by filling a resin material; 3, reinforcing the carbon fiber framework, namely reinforcing the carbon fiber framework at parts requiring reinforcement; 4, processing according to critical sizes, namely performing mechanical processing on the resin simulated block by using a numerically-controlled machine tool; and 5, matching, namely matching the simulated block with a main body frame of an automobile master model. The manufacturing process disclosed by the invention is high in processing precision and low in cost, and is particularly suitable for processing and manufacturing large-scale simulated blocks of automobile ceilings, engine covers, door plates or fenders and the like.

Description

technical field [0001] The invention relates to the technical field of automobile mold manufacturing, in particular to a manufacturing process of a carbon fiber simulation block of an automobile main model inspection tool. Background technique [0002] The simulation blocks of the main model of the car are designed and processed to simulate the real product parts in the car products. The simulation blocks in the main model checker can be exchanged with the real parts for product qualification inspection. At present, the simulation block of the main car model is mostly made of aluminum alloy material, which is processed by CNC. , Thinning the wall thickness of the analog block and other methods to reduce the weight of the analog block, a large number of weight-reducing holes and thinning the wall thickness will easily cause deformation of the analog block during CNC machining, resulting in poor precision, and cannot achieve the ideal effect of the inspection tool for testing ...

AI Technical Summary

Problems solved by technology

At present, the simulation block of the main model of the car is mostly made of aluminum alloy material by CNC machining. , Thinning of the wall thickness of the analog block and other methods to reduce the weight of the analog block, a large number of weight-reducing holes and thinning of the wall thickness will easily cause deformation of the analog block in the CNC machining, so that the accuracy is poor, and the ideal effect of the inspection tool for testing products cannot be achieved.

Secondly, design changes often occur in the development stage of new cars, and the modification of aluminum analog blocks is difficult, and the method of remanufacturing is generally used

Third, the processing performance of the aluminum analog block is not good, it is easy to stick to the knife, and the processing efficiency is low.

Finally, aluminum analog blocks can only be machined in one piece and cannot be mass-produced
