Description

Technical Field

[0001] The utility model relates to the technical field of lathe protective doors, in particular to a lathe protective device. Background Art

[0002] CNC machine tools will spray cutting fluid to cool the processed products and tools during the product processing process. The sprayed cutting fluid needs to wash away the waste chips generated by the tool processing. Generally, it has a large flow rate during spraying, and it may also cause the cut metal to splash, which will affect the operator. Most of the existing machine tool protective doors are opened and closed manually.

[0003] For example, the patent application number "201720603189.2" proposes a CNC machine tool protection door, which includes a first protection door and a second protection door. The first protection door and the second protection door are both soundproofed and noise-reduced by sound insulation and shock-absorbing layers and hollow glass components arranged inside them. However, the first protection door and the second protection door need to be opened and closed manually, which is time-consuming and laborious. To this end, we propose a lathe protection device.

The bottom of the connecting frame is connected to the guide seat, and the lower ends of the two guide seats are respectively located on the sides of the guide block;

[0009] A guide shaft is horizontally slidably provided in each guide seat, and both ends of the guide shaft are connected to the side of the guide block through a support. Buffer springs are sleeved on the guide shafts on both sides of the guide seat, and the buffer springs are in an elastic state;

[0012] Two moving seats are coaxially and threadedly connected on the bidirectional lead screw, the moving seats are respectively located below the guide blocks, and the moving seats are connected to the bottom of the side of the guide block through an L-shaped connecting frame;

[0013] One end of the bidirectional lead screw is connected with a reducer, and the other end of the reducer is connected with a driving motor. The reducer and the driving motor are both arranged on the side of the strip mounting plate.
