Description
Technical Field
The utility model belongs to the emery wheel field, concretely relates to cavity emery wheel.
Background
The grinding wheel is a bonded grinding tool which is formed by bonding a common grinding material into a certain shape (mostly circular, with a through hole in the center) by a bonding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classes of binders, ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels are common. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.
The scraps produced during grinding are easy to be blocked into other parts in work, so that the problems of component failure and the like are caused.

An object of the utility model is to provide a cavity emery wheel to better processing sweeps problem in the middle of the grinding.
In order to realize the purpose of the utility model, the technical method is as follows:
a hollow grinding wheel comprising:
a cylindrical grinding wheel base body, a grinding wheel base body,
a grinding wheel working layer fixed on the outer ring surface of the cylindrical grinding wheel base body,
wherein the middle part of the cylindrical grinding wheel base body is provided with a hollow flange connecting end with a T-shaped longitudinal section,
the grinding wheel working layer is equally divided into a plurality of parts along the central axis, a chip removal groove is formed in the bisector, a chip removal pipeline is vertically formed in one side of the hollow flange connecting end, which is close to the cylindrical grinding wheel base body, and a chip removal surface is obliquely arranged on the outermost side of the grinding wheel working layer.
In a preferred embodiment of the utility model, the emery wheel working layer is divided into six parts along central axis bisector and has seted up six junk grooves on the bisector.
In a preferred embodiment of the present invention, the width to depth ratio of the flutes is 1: 4.5.
in a preferred embodiment of the invention, the inclination angle of the chip surface is: inclined towards the base body by 10-15 deg.
In a preferred embodiment of the present invention, a plurality of bolt horizontal fixing grooves and a plurality of bolt vertical fixing grooves are further respectively formed on the side surface and the lower end surface of the cylindrical grinding wheel base body.
The beneficial effects of the utility model reside in that:
the chip removal surface and the chip removal groove of the grinding wheel working layer and the chip removal pipeline of the base body are arranged, so that the problem of waste chips in the grinding process can be better solved.

Detailed Description
The invention is further illustrated by the following examples:
referring to fig. 1 and 2, a hollow grinding wheel includes: the grinding wheel comprises a hollow cylindrical grinding wheel base body 100, wherein a hollow flange connecting end 110 with a T-shaped longitudinal section is arranged in the middle of the cylindrical grinding wheel base body 100 and used for integrally fixing the grinding wheel on a rack (not shown in the figure) after being connected with a flange. In addition, in order to fix the whole grinding wheel on the frame more firmly, two bolt horizontal fixing grooves 101a and 101b and six bolt vertical fixing grooves 102a, 102b, 102c, 102d, 102e and 102f are respectively formed on the side surface and the lower end surface of the cylindrical grinding wheel base body 100 for fixing the whole grinding wheel through bolts as required.
The grinding wheel working layer 200 is fixed on the outer ring end face 120 of the cylindrical grinding wheel base body 100, the grinding wheel working layer 200 is equally divided into six parts along the central axis, six chip grooves 201, 202, 203, 204, 205 and 206 are formed in the bisector, and the bolt vertical fixing grooves 102a, 102b, 102c, 102d, 102e and 102f are respectively and correspondingly installed right below the chip grooves 201, 202, 203, 204, 205 and 206.
In order to make the chip removal effect better, the width to depth ratio of the chip grooves 201, 202, 203, 204, 205, 206 is 1: 4.5. a chip removal pipeline 130a, 130b, 130c is vertically arranged on one side of the cylindrical grinding wheel base body 100 close to the hollow flange connecting end 110. The outermost side of the working layer 200 of the grinding wheel is a chip surface 210 inclined at 10-15 deg. to the substrate (see fig. 3).
Because the structure is adopted, the utility model discloses a theory of operation lies in:
after the hollow flange connection end 110 is connected with a flange, the grinding wheel is integrally fixed on a frame (not shown in the figure), in order to fix the integral grinding wheel on the frame more stably, two bolt horizontal fixing grooves 101a and 101b and six bolt vertical fixing grooves 102a, 102b, 102c, 102d, 102e and 102f are respectively formed in the side surface and the lower end surface of the cylindrical grinding wheel base body 100, and the grinding wheel is integrally fixed through bolts according to needs.
After the grinding wheel is fixed, the frame is started, the grinding wheel integrally rotates under the driving of the frame and the flange, the grinding wheel working layer 200 is in contact with a hard material to be ground to grind the material, and scraps generated in the processing process are discharged in a rotating mode through the scrap discharge surface 210 or are discharged into the hollow part of the cylindrical grinding wheel base body 100 through the scrap discharge grooves 201, 202, 203, 204, 205 and 206 and then are discharged along the scrap discharge pipelines 130a, 130b and 130 c.
