Description

Technical Field

[0001] This utility model relates to the design of a tooling, and more particularly to a tooling for turning a deep inclined groove on a thin-walled outer circle. Background Technology

[0002] Existing technologies often involve machining deep inclined grooves on thin-walled outer diameters, see [link to relevant documentation]. Figure 3 Part 1 is made of 7050 pre-stretched aluminum plate. Its outer diameter has a deep inclined groove 1-1, and the inner hole sidewall is composed of conical surfaces 1-4, spherical surfaces 1-5, and cylindrical surfaces 1-6. Part 1 has a wall thickness of only 1.2mm, making it a large, thin-walled, easily deformable rotating part. In the current technology for machining the deep inclined groove 1-1 on the outer diameter, a combination fixture is generally used. However, the positioning surfaces are difficult to match with the conical surfaces 1-4, spherical surfaces 1-5, and cylindrical surfaces 1-6 on the inner hole sidewall, resulting in low positioning accuracy, difficulty in ensuring part machining quality, and significant time spent assembling and adjusting the fixture, extending the machining cycle and reducing machining efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide a tooling for turning a deep inclined groove on a thin-walled outer circle, which solves the problems of low positioning accuracy, low part processing quality, and long assembly time.

[0004] The technical solution of this utility model is as follows: The tooling for machining a deep inclined groove on a thin-walled outer circle is used to process part 1, including a positioning plug 2, a clamping end cap 3, a bolt 4, and a washer 5, wherein: the outer circle of part 1 is a deep inclined groove 1-1, one end is a large thin-walled end face 1-2, and the other end is a small cylindrical end face 1-3, and the inner hole sidewall is composed of a conical surface 1-4, a spherical surface 1-5, and a cylindrical surface 1-6; the positioning plug 2 includes a positioning surface 2-1, a fixing hole 2-2, a thin-walled placement groove 2-3, a clamping cylindrical surface 2-4, and a threaded hole 2-5; the clamping end cap 3 includes a fixing cylindrical surface 3-1, a clamping end face 3-2, and a bolt hole 3-3; the bolt 4 includes a threaded cylindrical surface 4-1 and a fastening hexagonal body 4-2; the washer 5 includes a cylindrical hole 5-1 and an end face 5-2. Furthermore, the positioning surface 2-1 of the positioning plug 2 mates with the conical surface 1-4, spherical surface 1-5, and cylindrical surface 1-6 of the inner hole sidewall of part 1.

[0005] Furthermore, the thin-walled mounting groove 2-3 of the positioning plug 2 mates with the large thin-walled end face 1-2 of the part 1.

[0006] Furthermore, the fixing hole 2-2 of the positioning plug 2 and the fixing cylindrical surface 3-1 of the pressing end cap 3 are in clearance fit.

[0007] Furthermore, the fixed cylindrical surface 3-1 can rotate freely in the fixing hole 2-2 of the positioning plug 2.

[0008] Furthermore, the pressing end face 3-2 of the pressing end cap 3 mates with the small cylindrical end face 1-3 of the part 1.

[0009] Furthermore, the cylindrical surface 4-1 of the bolt 4 mates with the cylindrical hole 5-1 of the washer 5.

[0010] Furthermore, the cylindrical surface 4-1 of the bolt 4 mates with the threaded hole 2-5 of the positioning plug 2 and the bolt hole 3-3 of the clamping end cap 3.

[0011] Furthermore, the clamping cylindrical surface 2-4 of the positioning plug 2 is connected to the lathe three-jaw chuck.

[0012] Furthermore, the bolt 4, washer 5, and clamping end cap 3 fix the part 1 to the positioning plug 2.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, this technical solution has high tooling positioning accuracy, which can ensure the processing quality of the parts. At the same time, through the cooperation with the tooling, the structural strength of the parts is improved and the deformation of the parts during processing is avoided. The fixing hole 2-2 of the positioning plug 2 cooperates with the fixing cylindrical surface 3-1 of the clamping end cover 3. On the one hand, it plays the role of supporting the clamping end cover 3, making the operation convenient. On the other hand, the fixing cylindrical surface 3-1 can rotate freely in the fixing hole 2-2 of the positioning plug 2, quickly aligning the threaded hole 2-5 of the positioning plug 2, and quickly fixing the bolt 4, washer 5, clamping end cover 3 and part 1 on the positioning plug 2, shortening the processing time of the deep inclined groove 1-1 of part 1.

[0028] Furthermore, the thin-walled mounting groove 2-3 of the positioning plug 2 mates with the large thin-walled end face 1-2 of the part 1.

[0029] Furthermore, the fixing hole 2-2 of the positioning plug 2 and the fixing cylindrical surface 3-1 of the pressing end cap 3 are in clearance fit.

[0030] Furthermore, the fixed cylindrical surface 3-1 can rotate freely in the fixing hole 2-2 of the positioning plug 2.

The bolt 4 and washer 5 are fitted with the threaded hole 2-5 of the positioning plug 2 and the bolt hole 3-3 of the clamping end cover 3 to fix part 1 on the positioning plug 2. The clamping cylindrical surface 2-4 of the positioning plug 2 is clamped on the three-jaw chuck of the lathe to achieve machining of the deep inclined groove 1-1 of part 1.

[0037] In summary, this utility model relates to a tooling for turning a deep inclined groove on a thin-walled outer diameter. The outer diameter of the part is a deep inclined groove, with one end being a large thin-walled end face and the other end being a small cylindrical end face. The inner hole sidewall is composed of a conical surface, a spherical surface, and a cylindrical surface. The tooling includes a positioning plug, a clamping end cap, bolts, and gaskets.
