Thin wall type bogie skirtboard aluminum profile processing universal tooling

Abstract

The invention discloses thin wall type bogie skirtboard aluminum profile processing universal tooling. The tooling comprises a bottom plate, a positioning strip, a bogie skirtboard outer surface supporting positioning mechanism, and a bogie skirtboard inner surface clamping positioning mechanism; the bogie skirtboard outer surface supporting positioning mechanism is provided with a first nylon cushion block; the bogie skirtboard inner surface clamping positioning mechanism is provided with a second nylon cushion block; and a positioning space of a bogie skirtboard is formed between the first nylon cushion block and the second nylon cushion block. The tooling realizes clamping positioning and fixation of the bogie skirtboard through the bogie skirtboard outer surface supporting positioningmechanism and the bogie skirtboard inner surface clamping positioning mechanism; at the same time, the first nylon cushion block and the second nylon cushion block are arranged on the bogie skirtboardouter surface supporting positioning mechanism and the bogie skirtboard inner surface clamping positioning mechanism respectively, so when tooling is in contact with the bogie skirtboard, the toolingis matched with the surface form of the bogie skirtboard and damage to the bogie skirtboard can be reduced by shock reduction effect of the nylon cushion blocks; and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of high-speed EMU parts processing, in particular to a general tooling for processing thin-walled bogie skirt plate aluminum profiles. Background technique [0002] The bogie apron of the high-speed EMU is the missing part that wraps the bogie under the EMU. It has a smooth arc of the EMU, and various observation windows, water injection ports and other holes are all over it. Unlike other skirts, bogie skirts are of single-layer structure, and their strength is lower than other types of skirts. According to the traditional apron processing method, the vibration is relatively large during processing, which produces strong noise, and it is not easy to clamp and easily deform. [0003] The first method in the prior art is to position and fix the bogie skirt by using simple spacers, pressure plates, and screws; since the bogie skirt is a circular arc surface, the proposed spacer that follows the contour is actu...

AI Technical Summary

Problems solved by technology

Excessive force is prone to deformation, poor workmanship, and large deformation during processing

There are many processing parts of the workpiece, and one clamping cannot guarantee to process all the parts to be processed. It is necessary to change the clamping method and then re-clamp, align, and process, which wastes mold changing time, and it is difficult to guarantee the machining accuracy of the secondary alignment; The clamping area of ​​this method is too small, and the clamping is not firm, so that the workpiece is prone to movement during processing, resulting in irreparable defects such as gnawing knives, resulting in waste products

Moreover, serious noise is generated in this way, which cannot be effectively solved

[0004] The second method in the prior art is to reduce noise by adding a soundproof cover to the machine tool, but the cost of adding a soundproof cover is high, and the cost increases by tens of thousands or even hundreds of thousands according to the size of the machine tool; the soundproof cover is installed in the studio It is not convenient to observe the workpiece. Machining usually uses a cooling medium to cool the tool and the workpiece. Whether it is coolant or oil, it will pollute the sound insulation cover and affect the observation and monitoring of the machining process.

The processing efficiency is reduced, and the sound insulation cover will try to be as sealed as possible, which affects the efficiency of clamping and lifting and unloading
