When the support column 203 is in the vertical position, the support column 203 is supported downward on the ground, and the broach assembly 100 clamped and fixed on the broach clamping seat 202 is in a horizontal state. When the broach clamping seat 202 is in an upright state, the broach assembly 100 clamped and fixed on the broach clamping seat 202 is in an upright state. Specifically, the first movable clamp and the second movable clamp can be respectively installed at both ends of the length direction of the broach clamping seat 202.

The second movable clamp may include a second clamp cylinder 206 and a top column 207 connected to the piston rod of the second clamp cylinder 206. The telescopic movement of the second clamp cylinder 206 makes the top column 207 approach or move away from the broach box 101 of the broach assembly 100, so that the top column 207 contacts the broach box 101 of the broach assembly 100 and cooperates with the first end of the clamping beam 204 to clamp the broach box 101 of the broach assembly 100. In addition, a broach box support block 208 can also be installed in the middle of the broach clamping seat 202 to support the broach box 101.

[0032] See also Figure 2 , Figure 7 and Figure 8According to a specific embodiment of the present application, the broach extraction mechanism 400 includes a lifting drive device 406 (such as a hydraulic cylinder, a pneumatic cylinder, etc.) and a rotation drive device 407 (such as a rotation drive motor, etc.), the extraction mechanism main body 401 is connected to the rotation drive device 407, the rotation drive device 407 can be rotatably arranged on the lifting drive device 406 around a vertical axis and can drive the extraction mechanism main body 401 to drive the first hanging plate 402 and the second hanging plate 403 to rotate around the vertical axis, the lifting drive device 406 and the mobile drive device 407 are connected to the lifting drive device 406. The mechanism 300 and the rotary drive device 407 are respectively connected to be able to drive the rotary drive device 407 to move up and down relative to the mobile drive mechanism 300. After the broach extraction mechanism 400 extracts the broach assembly 100 in an upright state at the broach loading station 11, the extracted broach assembly 100 can be moved along the guide rail truss 3 by the broach extraction mechanism 400 and the lifting and rotating of the extraction mechanism main seat 401 around the vertical axis, so that the insertion hole 103 on the broach box 101 is inserted into place by the insertion column 41.

[0033] During the specific operation, the broach clamping seat 202 is first in a horizontal lying state, the broach box 101 of the broach assembly 100 is horizontally installed (in a horizontal state) on the broach clamping seat 202, and the broach 102 thereon is arranged downward, and then the flip drive motor 201 drives the broach clamping seat 202 to rotate 90° from the horizontal lying state to an upright state. At this time, the broach assembly 100 is flipped to an upright state and the broach 102 faces the broach fixing frame 4, and the insertion hole 103 on the broach box 101 faces away from the broach fixing frame 4. At this time, the movement of the broach extraction mechanism 400 (lifting, rotating, and lateral movement along the guide rail truss 3, etc.) makes the first hook 404 and the second hook 405 of the broach extraction mechanism 400 hook the first hanging column 106 and the second hanging column 105 on both sides respectively. The second hanging column 107 extracts the broach assembly 100, and then the broach clamping seat 202 releases the clamping of the broach box 101 of the broach assembly 100, so that the broach extraction mechanism 400 moves along the guide rail truss 3, as well as lifts and rotates around the vertical axis, gradually allowing the column head 412 of the inserted column 41 to enter the main hole 104 first. When the column head 412 has completely passed through the boss 108, the broach box 101 is lowered, and then the main column body 411 gradually enters the long groove 105 until the upper side surface of the boss 108 contacts and supports on the main column body 411, and the side surface of the column head 412 facing one side of the main column body 411 abuts against the boss 108 to limit the boss, and finally until the back of the broach box 101 abuts against the broach fixing frame 4, thereby completing the loading operation of the broach assembly 100. When the broach assembly 100 on the broach fixing frame 4 needs to be taken out, similarly, the broach extraction mechanism 400 can be moved (lifted, rotated, and moved horizontally along the guide rail truss 3, etc.) so that the first hook 404 and the second hook 405 of the broach extraction mechanism 400 respectively hook the first hanging column 106 and the second hanging column 107 on both sides to extract the broach assembly 100, and then the broach extraction mechanism 400 moves along the guide rail truss 3 and rotates around the vertical axis to gradually make the insertion column 41 leave the insertion hole 103 until the broach assembly 100 is completely removed. Separated from the broach fixing frame 4, the mobile driving mechanism 300 then drives the broach extraction mechanism 400 to move along the guide rail truss 3 to the broach changing station, and then the broach assembly 100 is taken away and installed on the broaching processing equipment to realize the initial loading or replacement of the broach assembly 100. According to one embodiment, the broach extraction mechanism 400 can have the function of installing the broach assembly 100 on the broaching processing equipment, or, according to another embodiment, the broach assembly 100 on the broach extraction mechanism 400 can also be installed on the broaching processing equipment through other additional devices.
