The control bolt 44 is threadedly connected to the tooling seat 2, and the control bolt 44 is rotatably connected to the side of the control plate 43 away from the air storage bag 42.

[0035] See also Figure 5 and Figure 6 When the control bolt 44 rotates forward, the control bolt 44 drives the control plate 43 to squeeze the air bag 42. At this time, the air in the air bag 42 flows into the control air bag 41 through the air pipe. At this time, the control air bag 41 expands, pushing the connecting block 252 away from the receiving groove 21. At this time, the connecting column 251 drives the linkage plate 25 to move downward, so that the positioning column 3 moves downward.

The mounting blocks slide in the mounting grooves 31.

[0037] The milling equipment also includes a transmission component 5, which is arranged on the positioning column 3. When the positioning column 3 slides into the receiving groove 21, the transmission component 5 drives the positioning block 32 to slide and protrude out of the installation groove 31, so that the positioning block 32 abuts against the workpiece, limiting the positioning block 32 from moving out of the receiving groove 21.

[0038] The transmission assembly 5 includes a transmission column 51 and an elastic rope 52. The elastic rope 52 is located in the installation groove 31. The two ends of the elastic rope 52 are respectively fixedly connected to the opposite sides of the two relative positioning blocks 32. The elastic rope 52 is made of elastic material. When the elastic rope 52 is released, the two relative positioning blocks 32 are pulled closer to each other, and the two positioning blocks 32 slide into the installation groove 31 at the same time, so that the workpiece can be separated from the positioning column 3.

[0039] The transmission column 51 slides up and down in the positioning column 3. The top of the transmission column 51 is provided with an arc surface structure, and the bottom of the transmission column 51 protrudes out of the positioning column 3.

[0043] See also Figure 5 and Figure 7 The positioning column 3 is provided with a clamping assembly 6. When the upper column 33 and the lower column 34 rotate relative to each other, the clamping assembly 6 drives the expansion airbag 344 to expand, so that the connecting ring 343 moves toward the upper limit ring 341, driving the connecting ring 343 and the upper limit ring 341 to cooperate with each other to clamp the linkage plate 25. At this time, the positioning column 3 enters a fixed state.

[0044] The clamping assembly 6 includes a power block 61, a power airbag 62, a power tube 63, a power tooth 64 and a limit tooth 65. The lower column 34 is provided with a power arc groove 345, which extends circumferentially on a horizontal plane and is arranged around the power column 331.

[0045] See also Figure 5 and Figure 6 When the position of the positioning column 3 needs to be adjusted, first pass the positioning column 3 away from the first clamping plate 22 and the second clamping plate 23 through the workpiece, and place the workpiece against the groove wall of the accommodating groove 21 away from the first clamping plate 22 and the second clamping plate 23; then after taking out the workpiece, pinch the lower column 34 and rotate the upper column 33, at this time, the lower column 34 and the upper column 33 rotate relative to each other.

[0046] See also Figure 5 and Figure 7 When the lower column 34 and the upper column 33 rotate relative to each other, the power block 61 slides in the power arc groove 345 to squeeze the power airbag 62, and at the same time, the sliding teeth slide on the limiting teeth 65 to limit the power block 61 from sliding in the opposite direction; when the power airbag 62 is squeezed, the air in the power airbag 62 flows into the expansion airbag 344 through the power tube 63, so that the connecting ring 343 and the upper limit ring 341 cooperate with each other to clamp the linkage plate 25, thereby fixing the positioning column 3; after that, the workpiece is matched with the already fixed positioning column 3 and placed in the accommodating groove 21, and the next workpiece is placed and the positioning column 3 is fixed according to the same steps, until all the positioning columns 3 are fixed, the workpiece can be installed and fixed.

[0047] The implementation principle of a triangular milling device for a center group of a circular knitting machine in the embodiment of the present application is as follows: When milling the triangle, first place multiple workpieces one by one into the receiving groove 21, so that the positioning column 3 passes through the hole groove opened on the workpiece for the bolts and screws to pass through. Then turn the power bolt 24 to clamp the workpiece with the first clamping plate 22 and the second clamping plate 23. Then drive the control bolt 44 to rotate, so that the control plate 43 squeezes the air storage bag 42, driving the control air bag 41 to expand. At this time, the linkage plate 25 moves away from the receiving groove 21, driving the positioning column 3 to move toward the tooling seat 2, so that the transmission column 51 slides on the transmission surface 321, pushing the positioning block 32 to protrude outside the mounting groove 31, restricting the workpiece, and achieving the fixation of the workpiece. Finally, the milling equipment can be started, so that the milling cutter mills the workpiece to complete the triangle processing.
