Abstract
The invention relates to a novel two-procedure processing fixture for a passenger transport bogie frame, namely, a two-procedure processing fixture for a DJG5 new 200KM passenger transport bogie frame. The fixture comprises a bottom plate, wherein a locating structure matched with a processing center workbench is arranged on the lower surface of the bottom plate; nine groups of supports are connected onto the bottom plate; locating discs or floating supports, pressing plates and pressing plate supporting devices are mounted on the supports; two of the locating discs on the supports fix a workpiece to a tooling through adopting an one-plane two-bolt locating manner; the other two locating discs and the floating supports exert auxiliary locating and supporting functions; and the last support exerts a clamping function. The fixture has the advantages that the framework can be quickly and accurately fixed to the tooling, so that the production efficiency is improved, the labor intensity is reduced, and the processing cost is reduced.
Description
Technical field
The invention belongs to locomotive positioning tool field, particularly relate to a kind of passenger transporting framework two working procedure processing fixture, the i.e. new 200KM passenger traffic framework two working procedure processing fixture of DJG5.
Background technology
Along with socioeconomic development and progress, the increase to Passenger Electric Locomotive demand, the load-carrying of Passenger Electric Locomotive, speed and workmanship are also required that more and more higher.The new 200KM passenger traffic framework of DJG5 is the vitals of bogie, playing a part to connect driver element and whole car body, its serviceability and security performance and require of a relatively high, the structure of product is complicated, manufacturing precision prescribed is high, and safe operation plays vital effect.
In modern mechanical processing industry, owing to the working ability of lathe is all in steady improve, Digit Control Machine Tool is as a kind of high accuracy, high efficiency, automatization's process unit that stability is strong, have become as today that mechanotronics develops rapidly, the requisite state-of-the-art technology device of machinery industry, automatic numerical control machine tool starts to enter on a large scale machinery manufacturing industry.If machining based conception also rests on former machine tool and is processed, using multiple working procedure to process same workpiece, which not only adds substantial amounts of human and material resources, operation connects, and wastes non-cutting time unnecessary in a large number, and its operating cost is high, efficiency is low.
In view of the structure of the framework of this locomotive is complicated, if traditionally processing technique, non-cutting time length, operation many, put into lathe many, the inefficiency of quantity etc., now need to provide a kind of clamp for machining, solve the special size requirement with lower procedure connection, to adapt to the modern processing industry step of nowadays high speed development.
The present inventor is by relevant design and manufactures processing experience, the various problems run in the processing of present DJG5 new 200KM passenger traffic framework are carefully analyzed, a kind of new 200KM passenger traffic framework two working procedure processing fixture of DJG5 is proposed, workpiece determines benchmark without line, directly use this fixture to load onto workpiece and can process qualified product, and then manufacturing procedure can be shortened, improve production efficiency, it is applicable to produce in enormous quantities, to meet the Production requirement of locomotive.
Summary of the invention
It is an object of the invention to provide a kind of without line, semi-finished articles can directly be installed the frock clamp of centering, can conveniently be installed, reduce non-cutting time, reduce labor intensity and the number of workman, improve productivity and quality, reduce manufacturing cost, make the batch production of the new 200KM passenger traffic framework of DJG5 be smoothed out.
The object of the present invention is achieved like this, and base plate lower surface is provided with the location structure matched with numerical control Longmen boring-milling machining center workbench, and the location for framework has four location to support, four float supports, a clamped seat.Four positioning supports are also equipped with four set hold down gags simultaneously.Being placed in frock by framework, Z-direction seat surface is against four locating surfaces, and X-axis, Y direction are fixed by the hole, location of two location dishes and spring base, and workpiece pressing completes to be installed.This fixture advantage is in that to be fixed in frock quickly and accurately by framework semi-finished product, thus improving production efficiency, reducing labor intensity, reducing processing cost.
This frock includes a base plate, owing to base plate is shorter, consider to make full use of workbench, therefore base plate lower surface has 2 A28h6 positioning keys fixing on the table, frock can move in X-direction, after ensureing every time to change frock, only needing centering and reset coordinate system X-direction and can normally use, other frocks can be placed in the vacant position of workbench.
This frock has five set hold down gags, adds at framework and play pressuring action man-hour.
Having positioner everywhere in this frock, wherein two place's positioning discs adopt plane and two pits mode and workpiece spring base in X, Y direction location, and the plane of four positioning discs positions in Z-direction with workpiece spring seat surface.
In sum, the new 200KM passenger traffic framework two operation fixture of DJG5 of the present invention can make to be framed in the middle of the course of processing, just without line can be fixedly clamped quickly and accurately and be processed, substantial amounts of time and labour force are saved, greatly improve production efficiency, and Tooling axiom is simple, operates simple and easy.
