Embodiment 1

[0063] An abrasive abrasive tool structure with a rapidly removable abrasive layer, comprising a grinding wheel base 10, an adhesive layer 20 and an abrasive layer 30, the abrasive layer 30 is radially bonded on the outer diameter of the grinding wheel base 10 through the adhesive layer 20, wherein ,Such as Figure 2-4 As shown, the grinding wheel base 10 includes a heat collecting chamber 11 and a bonding groove 12 . Fitting grooves 12 are distributed around the outer diameter of the grinding wheel base 10 , and the fitting grooves 12 communicate with the heat-gathering cavity 11 through the heat conduction opening 13 .

[0064] Such as Figure 5 As shown, the inside and outside of the heat conduction port 13 is in a figure-eight shape. There are multiple heat-gathering chambers 11 distributed radially in the grinding wheel base 10 . The multiple heat-gathering chambers 11 communicate with each other.

[0065] Such as Figure 4 , 5 As shown, the abrasive tool structure ...

Embodiment 2

[0077] An abrasive tool structure having a rapidly removable abrasive layer, wherein, as Figure 10 , 11 As shown, there is a guide block 151 on the side of the second connection port 15, and the end surface of the guide block 151 facing the outside of the second connection port 15 is an inclined surface. The side end of the guide block 151 is provided with a transmission block 152. The surface is an inclined surface, and one end of the transmission block 152 is provided with a connecting ball 153, and the transmission block 152 is connected with a return spring 154.

[0078] When the heating head 70 is inserted into the second connection port 15, it moves against the guide block 151. After the guide block 151 moves, it pushes the transmission block 152 to move outward, so that the connection ball 153 on the transmission block 152 protrudes to the outside of the grinding wheel base 10. At this time , the connecting ball 153 snaps into the fixing plate on the side of the heati...

Embodiment 3

[0081] A method for quickly removing an abrasive layer, comprising the following steps:

[0082] Screw the threaded barrel 60 of the second connection port 15 in the grinding wheel base 10, so that the threaded barrel 60 is separated from the column body 51 of the rotating column 50, and then turn the rotating column 50, so that the resisting teeth 52 on the column body 51 rotate upwards to push the heat conduction assembly 40 The pressure ring 41, the pressure ring 41 is forced to push the elastic rod 42 to bend and store force;

[0083] Insert the heat supply head 70 into the second connection port 15, so that the high-heat air provided by the heat supply head 70 converges into the heat-gathering cavity 11 of the grinding wheel base 10, reducing the heat loss of the high-heat air, so that the high-heat air flows along the heat-gathering cavity The heat conduction port 13 on the 11 heats the center of the metal sheet 43 in the bonding groove 12;

[0084] The metal sheet 43 h...

Abstract

The invention discloses an abrasive grinding tool structure capable of quickly removing an abrasive layer, and relates to the technical field of abrasive grinding tools. The structure comprises a grinding wheel basal body, a heat conduction assembly, a rotating column, and a thread cylinder. A metal sheet replaces a bonding layer to be connected with the grinding wheel basal body, so that when a heat supply head heats a heat gathering cavity of the grinding wheel basal body, the center of the metal sheet under an attaching groove can quickly gather heat and soften the bottom of the center of the bonding layer, and meanwhile, the metal sheet bears the pressure of the rotating column jacking up a pressure ring, so that an elastic rod is bent to accumulate force; after the bottom of the center of the bonding layer is softened, the elastic rod can extrude the metal sheet to bend and deform, so that a gap is formed between the metal sheet and the attaching groove, the gap is filled with hotair to heat the metal sheet in a large area so as to quickly soften the bonding layer; and meanwhile, the elastic force of the elastic rod always generates pushing force on the metal sheet so as to push away the abrasive layer on the grinding wheel basal body from the grinding wheel basal body. Therefore, by means of the structure, the grinding wheel basal body cannot be damaged at all, and the abrasive layer removing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of abrasives, in particular to an abrasives structure with a rapidly removable abrasive layer. Background technique [0002] The ceramic superabrasive abrasive tool is usually made of a grinding wheel substrate 10, a bonding layer 20 and an abrasive layer 30, such as figure 1 shown. The base of the grinding wheel is generally a disc-like part made of metal. The abrasive layer is generally an abrasive ring or an abrasive ring spliced ​​by several segments. The abrasive layer is consolidated on the base of the grinding wheel through an adhesive layer. The adhesive layer is composed of liquid resin glue It is air-dried and cured. [0003] Since the ceramic superabrasive abrasives participate in the grinding process is the abrasive layer part, which is also the part that is lost. The grinding wheel matrix only plays the role of supporting the abrasive layer and is not consumed during use. Therefore, the supera...
