Technical Field
[0001] The utility model belongs to the technical field of wood processing, in particular to a fixing device for a woodworking engraving machine. Background Art
[0002] Woodworking engraving machines are mainly used for wood processing, crystal, copper, aluminum, etc. to make it more beautiful. Engraving is a combination of drilling and milling processing in terms of processing principle. The positioning blocks on the market now directly fix the wood on the base. Although the wood can be fixed, it is easy to cause different specifications of wood to adjust the fixing method, that is, the fixed position, because of the different lengths of the wood. The workers need to adjust it constantly. The surface of the wood is unevenly stressed, which is easy to scratch the surface of the wood, affecting the quality of wood carving.

At this time, the fourth motor starts to drive the second bevel gear to rotate, and the second bevel gear rotates to drive the meshing first bevel gear to rotate. The rotation of the first bevel gear drives the rotating rod to rotate, and the rotating rod drives the fan blades to rotate, thereby blowing air outwards to form a negative pressure on the inner wall of the table board. The purpose of providing the second push plate is to prevent the air loss formed by the fan blades when the second push plate contacts, thereby blocking it. When the wood is placed on the top of the table board, the negative pressure will suck the bottom of the wood along the vent to prevent the wood from moving, thereby improving the practicality of the device.

[0034] A specific application of this embodiment is: by setting the clamping mechanism 7, the wood is placed on the top of the table top 1, and the third motor 702 is started to drive the bidirectional threaded rod 703 to rotate, and the bidirectional threaded rod 703 drives the third threaded block 704 to move, and the bidirectional threaded rod 703 is set. The purpose is to drive the third threaded block 704 to approach or move away through the rotation of the bidirectional threaded rod 703, so as to perform the clamping work. When the third threaded blocks 704 approach each other, they drive the first push plate 705 to approach, and the first push plate 705 pushes the inclined rod 710 to approach, and the inclined rod 710 drives the anti-slide plate 711 to approach.

The purpose of setting the first spring 709 is that when facing wood of different volumes, the first spring 709 is deformed by squeezing the anti-slide plate 711, so as to adapt to wood of different lengths and improve the practicability of the device.
[0035] By setting the suction mechanism 8, when the third threaded block 704 is driven by the bidirectional threaded rod 703 to approach each other, the third threaded block 704 pushes the hollow plates 712 to approach each other, and the third motor 702 pushes the second push plate 714 to approach. When the second push plates 714 on both sides are in contact, the second push plates 714 shrink toward the inside of the hollow plate 712, thereby squeezing the second spring 713.
