Problems solved by technology
In the prior art, hexagonal lathes are usually used to process thin-walled holes, which is easy to cause deformation
Due to the large depth and small diameter of the hole, it is easy to cause the drill bit to break during processing, and the coaxiality between the outer circle and the hole is extremely poor, which can no longer meet the clamping requirements of this type of product.

Embodiment Construction
[0018] The specific implementation, structure, features and functions of the tooling for machining thin-walled holes according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0019] see Figure 1 to Figure 3 , the tooling used for processing thin-walled holes of the present invention includes positioning sleeves 2 and connecting iron wires 3, wherein: two positioning sleeves 2 are connected by connecting iron wires 3, and a small cavity section 1 and a small cavity section 1 are formed between the positioning sleeves 2. A stepped cavity formed by the large cavity section 5. A plurality of mounting grooves 4 are evenly arranged on the outer wall surface of the positioning sleeve 2, and the connecting iron wires 3 are placed in the mounting grooves 4. The mounting groove 4 is a rectangular groove. Both the small cavity section 1 and the large cavity section 5 are cylindrical cavities, and a c...

The invention discloses a tool for processing a thin-walled hole. The tool comprises positioning sleeves (2) and connecting iron wires (3). The tool is characterized in that the two positioning sleeves (2) are connected through the connecting iron wires (3), a stepped cavity composed of a small cavity section (1) and a large cavity section (5) is formed between the positioning sleeves (2), the outer wall faces of the positioning sleeves (2) are evenly provided with a plurality of mounting grooves (4), the connecting iron wires (3) are placed in the mounting grooves (4), the mounting grooves (4) are rectangular grooves, the small cavity section (1) and the large cavity section (5) are both cylindrical cavities, and a tapered surface transition section is arranged between small cavity section (1) and the large cavity section (5). The tool is simple in structure, stable, reliable, economic, high in quality and high in pass rate and suitable for use and popularization of clamping of high-precision thin-walled products with middle deep holes and outer circles with steps.
Description
technical field [0001] The invention belongs to the technical field of processing and clamping devices, and in particular relates to a tool for processing thin-walled holes. Background technique [0002] High-precision thin-walled products with deep holes in the middle and steps on the outer circle (as shown in the attached Figure 4 ) is very common in production, and the processing of such thin-walled holes is very difficult. In the prior art, a hexagonal lathe is usually used to process thin-walled holes, which is easy to cause deformation. Due to the large depth and small diameter of the hole, it is easy to cause the drill bit to break during processing, and the coaxiality between the outer circle and the hole is extremely poor, which cannot meet the clamping requirements of this type of product. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a simple structure, stable and reliable, economical,...
