Problems solved by technology
[0004] However, when using the above-mentioned slotting tool, the positioning of the nut needs to be realized by the cooperation between the bisecting plane and the corresponding horizontal positioning surface and vertical positioning surface on the positioning platform, and it is also necessary to use a magnetic base for adsorption and fixation. Skew, human factors are greatly affected, it is not easy to guarantee product consistency and processing accuracy, and it is inconvenient to use

Embodiment Construction
[0026] An example of a nut slotting tooling of the present invention is Figure 1~Figure 8 As shown, it is a slotting tool for slotting a self-locking nut 40 on a twelve-point flange surface. The structure of the self-locking nut is as follows Figure 7 and Figure 8 As shown, it is provided with 6 nut grooves 41 uniformly distributed along the circumferential direction; the slotting frock includes a frock base 10, an operating rod 30 that is arranged on the frock base 10 and rotates with the frock base 10 to guide and move along the front and rear directions; The spring 20 is arranged between the tool base 10 and the operating rod 30 .
[0027] The tooling base 10 includes a connection base plate 11 and a sleeve 12. The sleeve 12 has a plane portion 13 that matches the surface of the connection base plate 11. The plane portion 13 is provided with threaded holes, and the connection base plate 11 is provided with corresponding screw holes for connection. The bottom plate 11 a...

The invention relates to a nut-grooving tooling. The nut-grooving tooling comprises a tooling base and an operating rod, the operating rod can be guided to move in a fore-and-aft direction, and is rotatably arranged on the tooling base, the front end of the operating rod extends out of the front end surface of the tooling base, and is provided with a chuck for clamping a machined nut, the front end surface of the tooling base is provided with more than two positioning grooves or positioning projections, the operating rod is provided with a positioning arm which is radially perpendicular to the operating rod, the positioning arm is provided with a raised structure or a sunken structure, and an elastic part which is used for applying backward acting force on the operating rod so that the raised structure or the positioning projections are embedded in the positioning grooves or the sunken structure along the fore-and-aft direction. The nut-grooving tooling does not need to depend on manual positioning operation and adopt a magnetic base attraction method for clamping, can ensure positioning precision, is convenient to use, and can help increase machining efficiency, and labor intensity is low.
Description
technical field [0001] The invention relates to a nut slotting tool. Background technique [0002] In some special occasions, the nut needs to be provided with slots on the end face. For example, the self-locking nut with twelve-point flange is widely used in aero-engines. Often, 6 radially through slots are provided on the straight part of the nut. Due to the special structure of the nut, it is generally difficult to directly clamp it on the vise, so it is difficult to process. [0003] The Chinese patent with the application number 201220304605.6 and the authorized announcement number CN 202752884 U discloses a slotted nut wire cutting and slotting tool, including a positioning table, a magnetic base and a clamping block for clamping nuts, wherein the positioning table is set There are horizontal positioning surfaces and vertical positioning surfaces perpendicular to each other; the magnetic base is provided with a horizontal surface and a vertical surface which closely c...
