Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grinding wheel for chip grinding, specifically a grinding wheel module reinforcing structure. BACKGROUND

[0002] The PCB board of the chip needs to be polished on the edge after cutting in the production process to remove the burrs of the PCB board.

[0003] In the prior art, the grinding wheel is generally used for polishing, and the PCB board in contact with the grinding head is polished during the rapid rotation of the grinding wheel, thereby removing the burrs. The grinding head in the prior art is generally fixed by bolts. This fixing method is prone to bolt loosening during high-speed rotation of the device. Once this situation occurs, the grinding head will be thrown out during high-speed rotation, causing safety risks. SUMMARY

[0004] The utility model aims at: in order to solve the problem raised in the prior art, provide a grinding wheel module reinforcing structure.

[0005] To achieve the above object, the utility model provides the following technical scheme: a grinding wheel module reinforcing structure, including the installation ring, a plurality of arc grooves are set up on one side of the outer end of the installation ring, the inside of the installation ring is set up annular groove through to the outside of the installation ring, the depth of the annular groove is greater than the depth of the arc groove, the annular groove is used for connecting a plurality of arc grooves, the inner wall of the arc groove is fixedly connected with the grinding head, and a plurality of the grinding heads in the rotating state are used for polishing the chip.

[0006] As a further scheme of the utility model: the inner cavity of the arc groove and the annular groove is filled with viscous glue, and the viscous glue is used to improve the connecting force between the outer wall of the grinding head and the inner wall of the arc groove.

[0007] As a further scheme of the utility model: a plurality of the arc grooves are equidistantly distributed along the circumference of the installation ring.

[0008] As a further scheme of the utility model: the outer wall of the grinding head is consistent with the inner wall of the arc groove.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] 1. The annular groove is set up, and the grinding head is fixedly connected with the arc groove through viscous glue. Compared with the bolt fixing method in the prior art, it is more firm and will not loosen during polishing. BRIEF DESCRIPTION OF DRAWINGS

[0015] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0016] Please refer to Figures 1-2 In the embodiments of the utility model, a grinding wheel module reinforcing structure includes a mounting ring 1, a plurality of arc grooves 2 are formed on one side of the outer end of the mounting ring 1, an annular groove 4 is formed in the inside of the mounting ring 1 and penetrates to the outside of the mounting ring 1, the depth of the annular groove 4 is greater than the depth of the arc groove 2, the annular groove 4 is used for connecting the plurality of arc grooves 2, the inner wall of the arc groove 2 is fixedly connected with a grinding head 3, the plurality of grinding heads 3 in the rotating state are used for grinding the chip, the inner cavity of the arc groove 2 and the annular groove 4 is filled with viscous glue, the viscous glue is used for improving the connecting force between the outer wall of the grinding head 3 and the inner wall of the arc groove 2, the plurality of arc grooves 2 are equidistantly distributed along the circumference of the mounting ring 1, and the outer wall of the grinding head 3 is consistent with the inner wall of the arc groove 2.

[0017] In the embodiments, first, when the grinding head 3 is installed, the viscous glue is extruded into the arc groove 2 and the annular groove 4, then the plurality of grinding heads 3 are inserted into the arc groove 2 one by one, and the arc groove 2 realizes sufficient contact between the two grinding heads 3, the annular groove 4 increases the contact nubs of the glue, then after waiting for the viscous glue to dry, the grinding head 3 can be fixed.

[0018] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
