In the figure: 1. the double-key composite broach comprises a double-key composite broach body 2, a fixed groove 3, a broach, 4, a replacing device, 4a1, a spring, 4a2, a pull rod, 4a3, a clamping block, 4a4, an inserting block, 4b1, a round rod, 4b2, a threaded rod, 5, a rear guide, 6, a positioning block, 7 and a connecting groove.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
example 1:
referring to fig. 1-6: in this embodiment, a double bond composite broach, including double bond composite broach main part 1 and broach 3, the inside of broach 3 is equipped with change device 4, change device 4 includes pull rod 4a2, the outside and the broach 3 slip of pull rod 4a2 link to each other, the outer wall of pull rod 4a2 cup joints with spring 4a1 mutually, the one end and the fixture block 4a3 of spring 4a1 are fixed to link to each other, the inner of pull rod 4a2 links to each other with fixture block 4a3 fixedly, the outer wall and the 4a4 looks joint of fixture block 4a3, the outer wall and the spread groove 7 of broach 4a3 of left side 4a4 are laminated mutually, the inner and the locating piece 6 of a plurality of locating pieces are laminated mutually with the compound broach main part 1 of double bond, thereby restrict the position of broach 3, the outer wall and the laminating of a plurality of broach 3 of double bond composite broach main part 1 mutually, the slope processing inclination of fixture block 4a4 and fixture block 4a3 is the same, make the fixture block 4a3 extrude 4a3 and fixture block 3 fixedly link to each other with fixture block 4a, the fixture block 4a3 is driven to the opposite to the fixed groove 4a3, the fixture block 4a is driven to the opposite the side of the fixed groove 4a2 when the fixture block 3 is driven to move with the fixed die 4a3, the fixture block 4a is fixed to the opposite to the fixed side of the fixture block 4a3, and the fixture block 4a is connected with the fixed 2, and the other is fixed to the other at the end of the fixture block 3 is fixed to the fixture block 3, and the fixture block 3 is driven to be connected to the outer side, and the fixture block is fixed to the fixture block 3 is fixed, and the outer side is fixed to the outer wall is compressed by the fixture groove is compressed and has the fixture groove is compressed.
