Milling machine fixture and clamping method for air fuel radiator core assembly

Abstract

The invention provides a milling machine fixture for an air fuel radiator core assembly, and a clamping method. The milling machine fixture comprises a flange locating plate, a mounting support base, an adjusting screw rod, a locating block, a pressing plate and a connecting locking piece. The flange locating plate can be rotated relative to the mounting support base to adjust the angle, the adjusting screw rod and the locating block can rise and fall so as to support and limit the air fuel radiator core assembly, and the pressing plate and the connecting locking piece are fixed to the flange locating plate. The milling machine fixture facilitates regulation, location and machining, the working efficiency is improved, the product performance consistency is guaranteed, and meanwhile the product appearance quality is improved.

Description

technical field [0001] The invention relates to a clamp for installing a milling machine and a clamping method using the clamp, in particular to a clamp and a clamping method suitable for an air-fuel radiator core assembly, and belongs to the technical field of mechanical processing. Background technique [0002] The air-fuel radiator is a part of the aircraft environmental control system. The core component in the air-fuel radiator is an important product component. The consistency of its manufacturing quality is particularly important. The product weight requirements are relatively strict, especially the appearance quality of the product is more important . Such as Figure 5 As shown, it is a three-dimensional view of the air-fuel radiator core assembly. The air-fuel radiator core assembly is a hollow cubic shell part. There is a circle of flange connection disc C on one end surface of the shell part. The flange connection Plate C needs to ensure that the flange surface i...

Problems solved by technology

[0003] for Figure 5 For the two positions to be milled of the core assembly of the hollow air fuel radiator, the existing clamping method is to use an assembly fixture, use the flange connection plate C as the positioning surface to stick to the fixture, and then apply a vertical force from the end surface where the waist groove is located. The pressure of the flange surface compresses the core assembly of the air-fuel radiator. This traditional alignment, adjustment, positioning and clamping method is not only difficult to align and clamp (when the flange connection plate C is used as the positioning surface to be close to the fixture, it cannot be aligned with the milling machine. platform rotation, lack of auxiliary support points, and the size of the auxiliary support force cannot be adjusted), the product quality is not good, and it is easy to cause deformation of the component clamping process (applying pressure from one end of the waist-shaped groove will easily cause the end surface where the waist-shaped groove is located to be damaged. In addition, due to the lack of compression structure of the flange connection plate, when the waist-shaped groove and the sag-reducing plane are processed, the flange surface of the flange connection plate is no longer flat), causing the product to be scrapped. In order to meet the actual needs of production, it is urgent to design A set of milling machine fixtures and corresponding clamping methods for air-fuel radiator core assemblies
