Description

A kind of cutter processing drum barrel ultra-deep inner chamber
Technical field
The utility model belongs to aero engine technology field, particularly relates to a kind of cutter processing drum barrel ultra-deep inner chamber, is mainly used in the processing of aero-engine drum barrel inner cavity of component.
Background technology
Aero-engine new construction drum barrel emerges in an endless stream, and drum barrel die cavity is dark, and difficulty of processing is large.Traditional drum barrel inner-cavity structure, as shown in Figure 1, the degree of depth of weld seam working position is less than core size; Adopt existing process tool, knife plate is arranged on the working position connecing and handle can be directly to and reach drum barrel inner chamber, adopts left and right two process tools to process.The structure of existing process tool, as shown in Figure 1, knife plate is connected by bolt with handle of a knife, and handle of a knife is arranged on cutter holder by bolt tightening again, is affected by human factors larger.The rigidity of cutter is poor, and work in-process easily produces vibration, affects the crudy of product; And the positioning transfer of cutter, installation accuracy and working (machining) efficiency are all relatively low.
In addition, the degree of depth of the weld seam working position of new construction drum barrel is greater than core size, adopts existing process tool directly to arrive and cuts position, cannot process, the ultra-deep inner-cavity structure of new construction drum barrel, as shown in Figure 2.
Utility model content
For prior art Problems existing, the utility model provides a kind of cutter that effectively can ensure the processing drum barrel ultra-deep inner chamber of ultra-deep inner cavity weld seam machining accuracy and crudy.
To achieve these goals, the utility model adopts following technical scheme, a kind of cutter processing drum barrel ultra-deep inner chamber, comprise knife plate and two blades, described blade is arranged on the front end of knife plate, the rear end of knife plate connects handle be located by connecting by being arranged on the mouse dental structure of knife plate rear end face and alignment pin and capto, and passes through bolt tightening; In described knife plate, be provided with inner-cooling structure, the outlet of described inner-cooling structure is arranged on the front end of knife plate, and capto connects handle and is connected with receiver.
Described blade adopts diamond shaped insert.
Described knife plate is provided with damping block.
Described damping block is set to two.
The beneficial effects of the utility model:
1, cutter of the present utility model adopts hilted broadsword plate double blade structure, can reduce and change knife plate and tool setting number of times; Knife plate of the present utility model is provided with damping block, can effectively suppresses to process chatter; The utility model selects capto to connect handle, realizes the fast automatic centering of handle of a knife and receiver, and ensures switching precision (0.002mm) therebetween; Knife plate of the present utility model and capto are connect handle and are located by mouse dental structure and alignment pin, and be bolted to connection, capto connects between handle and receiver and adopts capto self-centering to transfer, and improves the rigidity of cutter and location, installation accuracy, improves the crudy of piece surface;
2, work in-process, knife plate and capto connect handle and only need install once, pass through shirtsleeve operation, capto can be realized connect and to split quickly and accurately between handle and receiver and connect, reach and cutter is sent into drum barrel inner chamber, take out the object of cutter after processing, thus complete the processing of drum barrel ultra-deep inner chamber at different levels and effectively ensure weld seam machining accuracy and crudy;
3, cutter of the present utility model has project organization novelty, rationally, and location, switching precision are high, cutter good rigidly, is easy to features such as installing, crudy is stable; Meet the process requirements of drum barrel ultra-deep inner chamber, and efficiently solve the technical barriers such as cutter interference, working position cutter is unreachable, crudy is uncontrollable, machined surface quality is unstable; Change the design concept of traditional drum tube inner chamber process tool, breach the key problem in technology of ultra-deep inner chamber drum barrel process tool design, fill up the technological gap of domestic air mail manufacturing industry ultra-deep inner chamber drum barrel processing.Along with the continuous increase of product demand, this achievement, by playing larger effect, producing larger benefit, has profound significance.Cutter of the present utility model can be promoted the use of in aero-engine, power combustion engine identical structure drum barrel part, has broad application prospects.
