[0037] Embodiment 1 provides a lifting protection tooling for a vertical lathe, the tooling is powered by a driving mechanism 8, the driving mechanism 8 uses a transmission mechanism 7 to link an adjacent lifting mechanism 6, provides lifting power, drives the corresponding protective cover 4 to move, the movement of the protective cover 4 drives the movement of the arc baffle 3, the movement of the arc baffle 3 causes other protective covers 4 to also move under the linkage cooperation of their respective corresponding lifting mechanisms 6, so as to realize the overall lifting of the arc baffle 3, the lifting mechanism 6 adopts a lead screw structure, can lock the state of the corresponding lifting mechanism 6 through the transmission mechanism 7 in the absence of driving force, and fix and support the entire arc baffle 3 through other lifting mechanisms 6, so as to ensure the stability of the arc baffle 3;

[0038] The protection process is monitored by the infrared sensor 10. When the lathe needs to be operated, the corresponding lifting control switch 12 is pressed to start the driving mechanism 8 through the control mechanism 11 to raise the arc baffle 3. During the process, as long as the infrared sensor 10 does not detect the position of the arc baffle 3, the infrared sensor 10 brakes the lathe control switch 13 through the control mechanism 11, and there will be no response even if the staff touches it by mistake.

[0040] After use, the corresponding lifting control switch 12 is pressed to reversely operate the driving mechanism 8 through the control mechanism 11 to lower the arc baffle 3.

[0041] As a preferred embodiment 2, the lifting mechanisms 6 are all of the same structure and move synchronously, so that the arc-shaped baffle 3 is supported on all the lifting mechanisms 6 to ensure stability during lifting.

The driving mechanism 8 is arranged on one side of the screw rod 603 at the edge of the protective cover 4.

[0043] Example 3 provides a specific structure of the lifting mechanism 6, in which the lead screw 603 rotates around the bearing seat 605, driving the lead screw and the threaded sleeve 601 to move synchronously, so that the threaded sleeve 601 linked with the limit of the protective cover 4 makes a linear motion along the axial direction to achieve lifting, thereby driving the protective cover 4 to be lifted and lowered, and the lifting of the protective cover 4 drives the arc baffle 3 to be lifted and lowered synchronously.

The adjacent screw rod 603 is driven to rotate through the transmission mechanism 7, so that the corresponding threaded sleeve 601 matched with the screw on the screw rod 603 is lifted and lowered, thereby driving the protective cover 4 and the arc baffle 3 to lift and lower as a whole.

The gap between the blocking platform 9 and the workbench 2 serves as a buffer space for metal chips. The metal chips generated in the lathe studio are blocked by the arc baffle 3, and then fall into the space between the blocking platform 9 and the workbench 2. When rising to the set position, the bottom of the arc baffle 3 is as close to the top of the blocking platform 9 as possible, and when it is completely lowered to expose the workbench, the arc baffle 3 is embedded into the blocking platform 9 along the hole.
