[specific embodiment]
Please refer to Fig. 2, Fig. 5, a kind of broaching tooling in starter end cap bushing hole, including a tool assembly 1,2 and of a push broach
The middle part of positioning piece 3, the tool assembly 1 is equipped with a kerf 11；The top of the tool assembly 1 is recessed inwardly to form a holding part
12, one first open-work 13 is equipped at the bottom center of the holding part 12, the side wall 111 of the notch 11 is more than first open-work
13 side wall 131；The lower part of the push broach 2 has segment of cutting 21, and when in running order, institute is protruded into 2 lower part of push broach
State the first open-work 13.The push broach 2 also has lead-in cable 22, calibration segment 23 and handle segment 24, and the lead-in cable 22, segment of cutting
21, calibration segment 23 and handle segment 24 are set gradually from bottom to up.
Referring again to Fig. 2-4, the bottom center of the tool assembly 1 is equipped with the second open-work 14, when the push broach 2 passes through institute
The first open-work 13 is stated, is fallen into second open-work 14.It is equipped with a foam-rubber cushion 4 in second open-work 14, its role is to anti-
Impact and bounce are generated when thrust knife 2 is fallen.To the height of the height of the notch 11,1 baseplane of tool assembly to notch 11
It spends h and 14 diameter of the second open-work carries out scientific and reasonable design, smoothly can be tiltedly stood naturally after falling the push broach 2 second thoroughly
In hole 14, convenient for taking out the processing for carrying out next workpiece.
Referring again to Fig. 5-6, a centre bore 31 is equipped at the center of the locating piece 3, the locating piece 3 passes through in described
Heart hole 31 is inserted in the push broach 2, that is, is sheathed on the handle segment 24 of push broach 2, and hanging down for push broach 2 is played in the work for carrying out broaching
Straight positioning action.The locating piece 3 is circle, and the outer edge of the locating piece 3 is recessed inwardly, and four recesses 32 is formed, convenient for that will determine
