A method for uniform deburring of inclined wall drilling

Abstract

The invention discloses a clamp and method for even deburring for oblique wall drilling. The upper end face of a clamp disc-shaped base (1) is provided with a cylindrical first groove (3) concentric with the clamp disc-shaped base (1). A circle of cylindrical protrusion (7) is arranged in the cylindrical first groove (3) and is internally provided with a cylindrical second groove (2). A cylindrical penetrating hole (4) is formed in the outer side of the first groove (3) in the circumferential direction of the clamp disc-shaped base (1). The axis direction of the penetrating hole (4) is parallel to the axis direction of the clamp disc-shaped base (1). A first screw hole (5) is formed in the upper end face of the part, on the outer side of the penetrating hole (4), of the disc-shaped base (1). A positioning pin hole (6) is formed between the penetrating hole (4) and the cylindrical first groove (3) and in the upper end face of the disc-shaped base (1). According to the clamp and method, a turbine disc plane is clamped on the clamp, all the operation processes can be completed by one person, the component drilling quality is effectively controlled, a large amount of labor cost is saved, and the efficiency is improved by near 3 times.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, in particular to a method for drilling and deburring disk parts on an arc surface and a corresponding fixture. Background technique [0002] With the improvement of design capabilities and material properties, the structure of parts in the manufacturing process of aviation parts presents a complex development, and more and more complex surface processing requirements appear, processing difficulty increases, and the ability to process products The requirements are getting higher and higher, which poses a great challenge to ordinary traditional processing methods, which are time-consuming, labor-intensive, inefficient, and difficult to guarantee quality. Therefore, it is necessary to effectively solve such problems, improve processing efficiency, and stabilize processing quality. [0003] Such as figure 1 As shown, in order to solve the problem of drilling 32 ventilation holes...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, in order to solve the problem of drilling 32 ventilation holes in the second-stage turbine disk of a certain type of engine, the existing technical solution is to use a special positioning indexing fixture on a radial drilling machine for processing (such as figure 1 Shown is the clamping position of the part), when drilling and deburring, because the cylindrical surface is used to drill inclined holes and clamp the parts on the inclined surface, it is time-consuming and laborious, and drilling deviation is very easy to occur, so it is difficult to ensure the stability of drilling quality sex

Chamfering and deburring is purely manual, with high labor intensity and low efficiency. Based on the above situation, it is necessary to propose a new processing method to overcome the time-consuming, low efficiency, high labor cost of the existing processing method, and the special control effect and quality are difficult to impress. satisfactory question
