The utility model has the advantages of it is following:

1. the utility model discloses a die cavity, through-hole and screw hole have been seted up in the nut body and from top to bottom in order, through-hole intercommunication screw hole and die cavity, through-hole, screw hole and the coaxial setting of nut body, a plurality of spiral holes have been seted up on the outer cylinder of nut body and along its circumferencial direction, spiral hole sets up along the axial of nut body, the last port of spiral hole runs through the die cavity setting, the lower port of spiral hole runs through the outer cylinder setting of nut body, when carpenter's machining center utilizes the cutter to process wooden work piece, carpenter's machining center drives its main shaft rotatory, the main shaft drives the handle of a knife rotatory, the handle of a knife drives this dust absorption nut and cutter rotation, wherein the cutter drills or milling process on wooden work piece, and produce a large amount of dust on the machined surface, and the dust absorption nut produces the turbine pressure in the rotation process, the dust that, the dust passes through the lower port of the spiral hole, the upper port of the spiral hole and the cavity in sequence and finally enters the fan positioned at the top of the woodworking processing center, and the fan exhausts the dust into the collecting box, so that the dust generated when the wood workpiece is processed is removed, and the dust-free and environment-friendly operation of a workshop is ensured.

2. Because the dust collection nut is always positioned above the cutter, dust generated in processing is immediately pumped upwards, the dust is effectively prevented from remaining on the processing surface of a workpiece, the dust is further prevented from contacting with the cutter for the second time, the cutter is well protected, and the service life of the cutter is prolonged. In addition, as the dust is upwards pumped and discharged by the dust-absorbing nut for a certain height in advance, the dust can be completely pumped out by the fan, the problem that the suction force of the fan is not enough is not needed to be worried about, and the dust-absorbing nut has the characteristic of good dust-absorbing effect.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 1 to 3, a dust-absorbing nut comprises a nut body 1, wherein the nut body 1 is cylindrical, the nut body 1 is cylindrical or rectangular, in this embodiment, the nut body 1 is cylindrical, a cavity 2, a through hole 3 and a threaded hole 4 are sequentially formed in the nut body 1 from top to bottom, a side wall of the cavity 2 is arc-shaped, the cavity 2 and the through hole 3 are coaxially arranged, the through hole 3 communicates with the threaded hole 4 and the cavity 2, the through hole 3, the threaded hole 4 and the nut body 1 are coaxially arranged, a nominal diameter of the threaded hole 4 is larger than a diameter of the through hole 3, a plurality of spiral holes 5 are formed in an outer cylindrical surface of the nut body 1 and along a circumferential direction of the outer cylindrical surface, in this embodiment, the spiral holes 5 are uniformly distributed on the nut body 1, and a blind hole 8 located on the nut body 1 is formed between two adjacent spiral holes 5, spiral hole 5 sets up along the axial of nut body 1, and the last port in spiral hole 5 runs through the setting of die cavity 2, and the outer cylinder setting of nut body 1 is run through to the lower port in spiral hole 5.

As shown in fig. 1 to 3, an annular groove 6 is formed in the nut body 1 between the through hole 3 and the threaded hole 4. Step hole 7 is seted up to the bottom of nut body 1, step hole 7 and screw hole 4 intercommunication, step hole 7 and the coaxial setting of screw hole 4.

The working process of the utility model is as follows:

before the dust-absorbing nut is used, a worker sequentially penetrates the cutter clamping head 11 of the cutter handle 9 through the step hole 7, the threaded hole 4, the annular groove 6 and the through hole 3 from bottom to top, then the cutter handle 9 is rotated to enable the external threads on the cutter handle to be in threaded connection with the threaded hole 4, the dust-absorbing nut 10 is fixed on the cutter handle 9, then the cutter 13 is installed in the cutter clamping head 11 from top to bottom as shown in figures 4-7, and finally the conical rod 12 of the cutter handle 9 is installed on a spindle of a woodworking center.

When a woodworking center processes a wooden workpiece by using a cutter 13, the woodworking center drives a main shaft of the woodworking center to rotate, the main shaft drives a cutter handle 9 to rotate, the cutter handle 9 drives the dust-absorbing nut 10 and the cutter 13 to rotate, wherein the cutter 13 drills or mills the wooden workpiece and generates a large amount of dust on a processing surface, the dust-absorbing nut 10 generates turbine pressure in the rotating process, the dust on the processing surface is upwards sucked by the turbine under pressure, the dust sequentially passes through the lower port of the spiral hole 5, the upper port of the spiral hole 5 and the cavity 2 and finally enters a fan at the top of the woodworking center, and the fan pumps and exhausts the dust into a collecting box, so that the generated dust is removed while the wooden workpiece is processed, and the dust-free and environment-friendly operation of a workshop is ensured.
