Detailed Description

As shown in figures 1 to 6:

the invention provides a centerless cylindrical forming grinding wheel dressing device, which comprises a main body 1, a rotating handle 2, a rotating shaft 3 and a dresser 4, wherein one side of the main body 1 is embedded in the rotating handle 2, one side of the main body 1 is embedded in the rotating shaft 3, and one side of the rotating shaft 3 is embedded in the dresser 4;

the trimmer 4 comprises a trimming head 401, a negative pressure ring 402, a bushing 403 and a collecting plate 404, the top end of the trimmer 4 is fixedly connected with the trimming head 401, the negative pressure ring 402 is embedded around the trimming head 401, the bushing 403 is arranged inside the trimmer 4, and the collecting plate 404 is arranged inside the trimmer 4.

Wherein, the trimming head 401 further comprises a suction hole 4011 and a rotary groove 4012.

Wherein, suction hole 4011 opening sets up around the trimming head 401, and suction hole 4011 is the setting of heliciform annular arrangement, can take out the inside air of trimmer 4 through suction hole 4011 and make it produce the negative pressure and adsorb into inside the trimmer 4 with the abrasive dust that the trimming produced.

Wherein, the rotary slot 4012 opening sets up in the both sides of trimming head 401, and rotary slot 4012 is the annular recess for trimming head 401's both sides, can let negative pressure ring 402 rotate and can not drop on its trimming head 401 through rotary slot 4012.

Wherein, the negative pressure ring 402 further comprises a rotating ring 4021 and an air extracting ring 4022.

The rotary ring 4021 is fixedly connected to two ends of the negative pressure ring 402, and the rotary ring 4021 is embedded into the rotary groove 4012, and a part of the rotary ring 4021 protrudes from one side of the rotary groove 4012.

Wherein, bleed ring 4022 inlays and sets up between change ring 4021, and change ring 4021 is for being the heliciform setting, can take out the air in dresser 4 through suction hole 4011 when high-speed rotatory through bleed ring 4022 for the inside bottom of dresser 4 is absorbed to the abrasive dust that produces with dressing to produce negative pressure.

Wherein, swivel 4021 further includes a rotation shaft 40211 and a rotation groove 40212.

The rotating shaft 40211 is fitted into the rotary ring 4021, and a cylindrical body of the rotating shaft 40211 having a ring shape is provided in a hollow portion of the rotary ring 4021.

The openings of the rotating groove 40212 are disposed on the peripheral surface of the rotating shaft 40211, the rotating groove 40212 is a spiral groove, and the groove of the rotating groove 40212 is engaged with the groove inside the rotating ring 4021, so that the whole negative pressure ring 402 can be driven to rotate when the rotating shaft 40211 is driven to rotate when the grinding wheel rotates.

The working principle is as follows:

firstly, the dresser 4 is aligned to the rotating grinding wheel, then the dresser 4 is touched to the grinding wheel rotating at a high speed, then the edge of the grinding wheel is ground and dressed through rotation, meanwhile, the rotating shaft 3 can rotate to drive the dresser 4 to change the angle through rotating the rotating handle 2, so that the edge of the grinding wheel can be more comprehensively dressed and ground, meanwhile, the surface of the rotating shaft 40211 can be touched when the grinding wheel is abutted to the dressing head 401 to rotate and dress, the rotating shaft 40211 can be driven to rotate during friction, the whole negative pressure ring 402 can be driven to start rotating due to the fact that the grooves are matched with the grooves on one side of the inner wall of the rotating ring 4021 while the rotating shaft 40211 rotates, the air pumping ring 4022 can rapidly move from the surface of the suction hole 1 when the negative pressure ring 401402 rotates, and air inside the dresser 4 can be pumped out through rapid movement, make the inside of dressing head 401 form negative pressure and will absorb into the dresser 4 the abrasive dust when carrying out the finishing grinding, the last abrasive dust that inhales can reach on the collecting plate 404 through bushing 403, simultaneously because bushing 403 is the slope form setting for can not drive the abrasive dust on the collecting plate 404 when taking out the air and waft.
