Description

Technical Field

[0001] This utility model belongs to the field of grinding head technology, specifically relating to a hollow small-blade grinding wheel. Background Technology

[0002] Currently, diamond grinding wheels are commonly used in grinding devices to grind surface structures such as concrete and floor coatings. When used for scraping floor adhesive and removing old coatings, the main function of diamond grinding wheels is to remove the old coating. Existing technologies typically use PCD grinding tools, but simple diamond PCD cutter heads are expensive, have a small working area, slow grinding speed, and poor grinding effect. In view of this, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a hollow small cutter head grinding wheel, which has a deeper grinding depth than a solid cutter head.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hollow small blade grinding wheel, including a base and a blade, the blade being cylindrical, the blade having a through hole, the axis of the through hole coinciding with the axis of the blade, and the blade being fixedly connected to the surface of the base.

[0005] Furthermore, the cutter head has two rings, with multiple cutter heads in each ring, and the two rings of cutter heads are arranged alternately.

[0006] Furthermore, the number of cutting heads near the outer ring is twelve, and the twelve cutting heads are arranged at equal intervals.

[0007] Furthermore, the number of the cutting heads near the inner ring is six, and the six cutting heads are arranged at equal intervals.

[0008] Furthermore, the grinding wheel also includes multiple convex strips, which are located on one side of the cutter head, and the height of the convex strips is less than that of the cutter head.

[0009] Furthermore, the plurality of the aforementioned convex strips are spaced apart.

[0010] Furthermore, the substrate has multiple through holes, the number of which is the same as the number of through holes, and the through holes and through holes correspond to each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The grinding wheel of this utility model includes a base and a cutting head. The cutting head is cylindrical and has a through hole. One end of the cutting head is fixedly connected to the base. Compared with the solid cutting head used in the prior art, the grinding speed is faster and the grinding effect is better. Under the same pressure, the cutting head of this solution has a deeper grinding depth and higher grinding efficiency than the solid cutting head.

[0013] 2. The substrate has through holes, which correspond to the through holes. During the grinding process, grinding debris can be discharged well, preventing dust accumulation in the holes from affecting the operation of the cutting head. Attached Figure Description

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figure 1-2 As shown, this embodiment provides a hollow small blade grinding wheel 2, including a base 1, eighteen blades 2 and six protrusions 3.

[0019] The cutter head 2 is cylindrical and has a through hole 21. The axis of the through hole 21 coincides with the axis of the cutter head 2. The cutter head 2 is fixedly connected to the surface of the base 1. The base 1 has eighteen through holes. The number of through holes 11 is the same as the number of through holes 21. The through holes 11 and through holes 21 correspond to each other. During the grinding process, the grinding debris can be discharged well, preventing dust accumulation in the holes from affecting the operation of the cutter head 2.

[0020] The cutter head 2 has two rings. The outer ring has twelve cutter heads 2, which are evenly spaced. The inner ring has six cutter heads 2, which are evenly spaced. The two rings of cutter heads 2 are staggered.

[0021] Six raised strips 3 are located on one side of the cutter head 2. The height of the raised strips 3 is less than that of the cutter head 2. The six raised strips 3 are spaced apart. Specifically, the raised strips 3 are metal strips, and the metal material is aluminum alloy or iron. The thickness of the raised strips 3 is 1mm-1.5mm. In this solution, the thickness of the raised strips 3 is 1mm. The raised strips 3 are locked to the base 1 by screws. The function of the raised strips 3 is as follows: to prevent grinding on the base 1 during grinding; by observing the wear of the grinding wheel and the installation, if the raised strips 3 are damaged, it indicates that there is a problem with the installation of the grinding wheel or that some of the cutter heads 2 have reached their wear limit and need to be replaced.

[0022] The grinding wheel in this solution includes a base 1 and a cutting head 2. The cutting head 2 is cylindrical and has a through hole 21. One end of the cutting head 2 is fixedly connected to the base 1. Compared with the solid cutting head 2 used in the prior art, the grinding speed is faster and the grinding effect is better. Under the same pressure, the cutting head 2 in this solution has a deeper grinding depth and higher grinding efficiency than the solid cutting head 2.

[0023] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
