[0024] This facilitates clamping and limiting of components during the layer-by-layer assembly of the coal mill, resulting in a high degree of automation and ease of operation. Figure 1-3 As shown, the coal mill assembly limiting mechanism of this utility model includes a circular base plate 16, a supporting vertical plate 6 and a connecting plate 4. The supporting vertical plate 6 is installed at equal intervals on the top outer edge of the circular base plate 16 through a positioning plate 17 and positioning screws 18.

The output shaft of the servo motor 12 is connected to a lead screw 9 through a coupling and a lead screw block 10 is sleeved on the lead screw 9.

[0025] A slide rod 1 is bolted to one side of the wire block 10, and a connecting plate 4 is bolted to the other end of the slide rod 1. An electric cylinder 2 is mounted on one side of the top of the connecting plate 4 via a mounting seat. The output shaft of the electric cylinder 2 passes through the connecting plate 4 and is connected to an arc-shaped clamping plate 5. A circular rubber anti-slip pad 15 is laid on the top of the circular base plate 16 and between the supporting vertical plates 6.

[0026] In use, the coal mill is assembled layer by layer on the top of the circular base plate 16. The power supply of the servo motor 12 is turned on, and the servo motor 12 drives the lead screw 9 to rotate, so that the lead block 10 slides on the lead screw 9. The arc-shaped clamping plate 5 is adjusted to the height of the coal mill to be assembled ring. The power supply of the electric cylinder 2 is turned on, and the electric cylinder 2 drives the arc-shaped clamping plate 5 to move inward, which facilitates the clamping and limiting of the assembled parts and facilitates the tightening of the connecting bolts.

[0027] By using the rotation of the servo motor 12, the height of the next assembly ring is adjusted by the arc-shaped clamping plate 5, realizing continuous assembly. It has a high degree of automation, is easy to operate, is highly practical, and greatly improves production efficiency.

[0028] To avoid damage to the assembled parts during clamping, for example, such as Figure 1 As shown, the present invention also includes an electric cylinder controller 3 installed on one side of the connecting plate 4 and at the upper end of the electric cylinder 2 by screws. The output end of the electric cylinder controller 3 is electrically connected to the input end of the electric cylinder 2 by wires.

[0029] During use, the electric cylinder controller 3 automatically controls the output stroke of the electric cylinder 2 to avoid damage to the assembled parts during the clamping process.

[0030] For example, such as Figure 1 As shown, the present invention also includes a support block 13 evenly spaced on the bottom outer edge of the circular base plate 16, and a brakeable universal wheel 14 is bolted to the bottom of the support block 13.

[0031] When in use, the brakeable casters 14 make it easy to move the entire device to different positions.

[0032] For example, such as Figure 1 As shown, the present invention also includes a top plate 7 welded to the top of the supporting vertical plate 6, and the top end of the lead screw 9 is connected to the top plate 7 through a bearing 8.

[0033] When using it, make the lead screw 9 rotate stably and reduce shaking.

[0037] When in use, the top surface of the round rubber anti-slip mat 15 is resistant to dirt, does not easily stick to dust, is easy to clean, has a high coating strength, is not easy to peel off, and is durable.

[0038] When in use, the brakeable universal wheels 14 make it easy to move the whole device to different positions for use, and the coal mill is assembled layer by layer on the top of the circular base plate 16.

[0039] Turn on the power of the servo motor 12 and use the servo motor 12 to drive the lead screw 9 to rotate, so that the lead block 10 slides on the lead screw 9. Adjust the arc-shaped clamping plate 5 to the height of the coal mill assembly ring. Turn on the power of the electric cylinder 2 and use the electric cylinder 2 to drive the arc-shaped clamping plate 5 to move inward, so as to clamp and limit the assembly parts and tighten the connecting bolts.

[0040] By using the rotation of the servo motor 12, the height of the next assembly ring is adjusted by the arc-shaped clamping plate 5, so as to achieve continuous assembly. It has a high degree of automation, is easy to operate, and is highly practical, which greatly improves production efficiency.
