Embodiment 1

[0036] like figure 1 As shown in the figure, an adapter plate for tongue and groove broaching of disk parts includes an adapter plate body 1, the adapter plate body 1 is circular, and the adapter plate body 1 is sequentially opened along the diameter of the center of the circle to the outer circumference line. There are a first through hole 2, a second through hole 3 and a third through hole 4; the first through hole 2 is used to cooperate with the bottom hole of the external broaching fixture; the second through hole 3 is used to fix the broaching fixture; The third through hole 4 is used for connecting with an externally connected indexing plate.

Embodiment 2

[0038] The utility model relates to an adapter disk for tongue and groove broaching of disk parts, which is a connecting device used for broaching machine fixtures and indexing disks.

[0039] The adapter plate is used in conjunction with the broaching fixture and the broaching indexing plate, and its shape is as follows: figure 1 and figure 2 As shown, its diameter D1 matches the gap between the bottom hole of the broaching machine fixture, and D1 can be designed according to the general selection of the bottom hole of the broaching machine fixture; the threaded hole with a pitch circle of D2 and the keyway X1 are used to fix the broaching machine fixture, and the pitch circle D2 can be selected according to the broaching machine fixture. The design of the pitch circle of the fixture connection hole; through the inner holes of a set of countersunk holes D5 and D7 (D7 is a blind hole) with a pitch circle of D3 and the keyway X2, the adapter plate is connected to the indexing ...

Embodiment 3

[0041] An adapter plate for tongue and groove broaching of disc parts,

[0042] The bottom hole of the fixture of the third-stage turbine broaching machine is Ф133.37, the pitch circle of the countersunk hole is Ф241, and the keyway width is 19.01;

[0043] The diameter of the central mandrel of the original indexing plate used for broaching of this part is Ф133.37, the pitch circle D2 of the connecting threaded hole is Ф241, and the width of the keyway is 19.01;

[0044] The diameter of the central mandrel of the new indexing plate used for broaching of this part is Ф101.6, the pitch circle D3 of the connecting threaded hole is Ф350, and the width of the keyway is 20.64;

[0045] According to the above dimensions, the relevant dimensions of the adapter plate to be used are Ф133.37 for D1, Ф241 for D2, 19.01 for X1, Ф350 for D3, Ф101.6 for D7, and 20.64 for X2.

Abstract

The invention discloses an adapter plate for mortise broaching of disc parts and a disc part machining device, and belongs to the technical field of machining process equipment. A first through hole, a second through hole and a third through hole are sequentially formed in the diameter of an adapter plate body from the circle center to the outer circumference; the first through hole is used for being connected with a bottom hole of an external broaching machine clamp in a matched mode; the second through hole is used for fixing the broaching machine clamp; and the third through hole is used for being connected with an external index plate. By using the adapter plate, the problem that the broaching machine clamp cannot be shared due to the fact that the connecting pitch circles on different index plates are different is solved, the interchangeability of the broaching machine clamp is improved, the number of clamps is reduced, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of machining process equipment, and relates to an adapter disc for broaching disc parts and a disc part processing device. Background technique [0002] The axial tenon and groove processing of aero-engine disk parts needs to be broached one by one on the broaching machine to complete the final shape line and all tenon and groove processing. The indexing plate is completed one by one. At present, there are broaching machines and indexing tables of different ages, different countries, and different manufacturers in the production site. Due to the different pitch circles of the connecting holes between the indexing table and the broaching fixtures, the broaching fixtures in different equipment or different indexing When used on the plate, they cannot be interchanged, and a new broaching fixture is required, which takes a long cycle and costs a lot. Therefore, it is necessary to design an adapter plate to sol...
