Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to an anti-scratch end face grinding wheel. Background Art

[0002] Existing high-end double-face grinding equipment, such as the Peter-Wolter and Stahli double-face grinding machines, generally features automatic loading and unloading capabilities. This automatic loading and unloading not only saves labor costs but also improves processing efficiency. However, for end-face grinding wheels with bonded grinding wheels, collisions between the workpiece and the end-face grinding wheel during the loading and unloading process can easily scratch the edges of the grinding wheel, even causing partial breakage. Furthermore, during machining, irregularly shaped workpieces, such as those with teeth, can also scratch the edges of the grinding wheel, causing the wheel to warp and break, which in turn can scratch the workpiece and affect the grinding process. To avoid compromising machining quality, the end-face grinding wheel must be removed and repaired before normal use. However, this tedious loading and unloading process can disrupt production schedules. Therefore, to address these issues and technical needs, it is necessary to develop new end-face grinding wheels that can prevent scratches, breakage, and workpiece damage. Summary of the Invention

[0003] The purpose of the utility model is to provide a scratch-resistant end face grinding wheel with a simple structure and strong practicality. It effectively solves the problem in the existing technology that during the automatic loading and unloading process of the workpiece, the end face grinding wheel collides with the workpiece, causing the end face grinding wheel to be scratched or broken, or the edge of the end face grinding wheel is lifted during the processing, thereby scratching the workpiece.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A scratch-resistant end face grinding wheel comprises a base and a working layer; an annular member is provided on the inner edge and the outer edge of the working layer; the working layer and the annular member are located on the base; and the thickness of the annular member is consistent with that of the working layer.

[0006] In the utility model, the base is an annular structure with inner and outer edges; by arranging annular parts on the inner and outer edges of the working layer, the phenomenon of scratching or even breaking the end face grinding wheel and scratching the workpiece due to collision between the workpiece and the end face grinding wheel during automatic loading and unloading and processing of the workpiece is avoided.

[0007] Furthermore, the annular member is a resin annular member, a metal annular member or a ceramic annular member. The annular member is used to prevent the edge of the end face grinding wheel from being scratched or broken. A resin annular member is preferred. The specific material composition of the annular member is selected according to actual needs without affecting the realization of the technical effect of the utility model.

[0008] Furthermore, the annular member is an integral structure or a split structure; when the annular member is a split structure, the annular member is composed of a plurality of arc segments.

[0009] Preferably, the inner wall of the annular member located at the inner edge of the working layer is flush with the inner wall of the base; the outer wall of the annular member located at the outer edge of the working layer is flush with the outer wall of the base.

[0010] Preferably, the ring width of the annular member is 2 to 15 mm. Further preferably, the ring width of the annular member is 5 to 12 mm.

[0011] Preferably, the thickness of the working layer is 3 to 30 mm. Further preferably, the thickness of the working layer is 8 to 25 mm. The working layer is located on the substrate and is used for processing workpieces.

[0012] Furthermore, the working layer is composed of a plurality of grinding wheel blocks.

[0013] Furthermore, the grinding wheel block is a circular grinding wheel block or a polygonal grinding wheel block. As an example, the polygonal grinding wheel block can be a regular hexagonal grinding wheel block or a trapezoidal grinding wheel block, where the regular hexagonal grinding wheel block has a side length of 8 to 25 mm, and the trapezoidal grinding wheel block has a side length of 10 to 40 mm. The specific shape of the grinding wheel block is selected according to actual needs and does not affect the realization of the technical effects of the utility model.

[0014] Furthermore, there is a gap or no gap between the grinding wheel blocks. Further preferably, when there is a gap between the grinding wheel blocks, a filling layer is provided at the gap. During actual application, the grinding wheel blocks can be tightly bonded to the matrix with a gap between each grinding wheel block; or can be bonded to the matrix at intervals with no gap between each grinding wheel block, and selection is made as needed.

[0015] In the present invention, the substrate is a steel substrate, an aluminum substrate or a cast iron substrate. The specific material of the substrate is selected according to actual needs and does not affect the realization of the technical effect of the present invention.

[0016] In the present invention, the diameter of the base is 300-2000 mm, and the thickness is 20-100 mm.

[0017] As is common sense, the base is provided with conventional mounting holes, which are used to fix the end face grinding wheel, and the specific position is designed according to actual needs.

[0018] Due to the application of the above-mentioned technical solution, the anti-scratch end face grinding wheel of the utility model has the following advantages: the utility model solves the problem of easy scratching and edge breaking of the end face grinding wheel in the prior art by arranging annular parts on the inner edge and outer edge of the working layer, avoids the need for frequent disassembly and repair of the end face grinding wheel, and effectively guarantees the processing quality and production progress of the workpiece.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention; for example, the directions or positions indicated by terms such as "length", "width", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are based on the directions or positions shown in the accompanying drawings and are for ease of description only and should not be construed as limiting this technical solution.

[0025] The base, grinding wheel block, annular member, and filler layer materials used in this invention are all existing products, and the method for preparing the end-face grinding wheel is conventional. The invention's innovation lies in the fact that, by providing annular members on the inner and outer edges of the end-face grinding wheel's working layer, it solves the problem of existing end-face grinding wheels being easily scratched and broken, thereby ensuring the quality of the workpiece being processed and ensuring production progress. Example 1

[0026] like Figures 1 to 2 As shown:

[0027] A scratch-resistant end-face grinding wheel comprises a base 1 and a working layer 2; an annular member 3 is provided on the inner and outer edges of the working layer respectively; the working layer and the annular member are located on the base; the inner wall of the annular member located on the inner edge of the working layer is flush with the inner wall of the base; the outer wall of the annular member located on the outer edge of the working layer is flush with the outer wall of the base.

[0028] In this embodiment, the annular member is an integral 6101 epoxy resin annular member with a ring width of 5 mm.

[0029] In this embodiment, the thickness of the working layer is 10 mm, and the thickness of the annular member is consistent with the thickness of the working layer.

[0030] In this embodiment, the working layer is composed of a number of regular hexagonal grinding wheel blocks 201 with a side length of 15 mm. There are gaps between the grinding wheel blocks, and a filling layer 4 of 6101 epoxy resin is provided in the gaps.

[0031] In this embodiment, the regular hexagonal grinding wheel block is a diamond abrasive grinding wheel block. In actual application, it can also be a CBN abrasive grinding wheel block, which can be selected according to needs.

[0032] In this embodiment, the substrate is a steel substrate with an outer diameter of 700 mm, an inner diameter of 300 mm, and a thickness of 50 mm.

[0033] As is common knowledge, conventional mounting holes 5 are provided on the base.

[0034] The method for preparing the above-mentioned scratch-resistant end face grinding wheel is the existing technology: first, regular hexagonal grinding wheel blocks are bonded to the base at intervals of 1 mm to form a working layer, and then 5 mm of regular hexagonal grinding wheel blocks on the inner and outer edges of the base are ground off, and 6101 epoxy resin is filled in the gaps between the regular hexagonal grinding wheel blocks and the inner and outer edges of the working layer to form a filling layer and a ring-shaped part to obtain a scratch-resistant end face grinding wheel. Example 2

[0035] Based on the first embodiment, the present embodiment is different in that the filling layer is omitted, and the rest is the same. Example 3

[0036] Based on the first embodiment, the present embodiment is different in that each regular hexagonal grinding wheel segment is tightly bonded to the base body, and there is no filling layer. The rest is the same. Example 4

[0037] Based on the first embodiment, the difference of this embodiment is that the one-piece 6101 epoxy resin ring is replaced with an one-piece phenolic resin ring, and the rest is the same. Example 5

[0038] Based on the first embodiment, the difference of this embodiment is that the one-piece 6101 epoxy resin ring is replaced with an one-piece metal ring, and the rest is the same. Example 6

[0039] Based on the first embodiment, the difference of this embodiment is that the integrated 6101 epoxy resin ring is replaced with a split ceramic ring, which is composed of a plurality of ceramic arc segments, and the rest is the same. Comparative Example 1

[0040] On the basis of Example 1, the annular member is omitted, the inner diameter of the working layer is consistent with the inner diameter of the base, and the outer diameter is consistent with the outer diameter of the base. The existing commercially available end face grinding wheel is used. Figure 3 .

[0041] Application Experiment

[0042] The end-face grinding wheels of Example 1 and Comparative Example 1 were respectively installed on a Stahli double-end-face grinder and conventionally machined to produce workpieces with triangular blades with high angularity. The scratch-resistant end-face grinding wheel of Example 1 consistently and stably processed workpieces, resulting in qualified workpieces. The grinding wheel was consumed normally, with no edge chipping caused by collisions between the workpiece and the end-face grinding wheel. The end-face grinding wheel service life met customer requirements. However, the existing end-face grinding wheel (without a ring) scratched the edges of the regular hexagonal grinding wheel block eight times during grinding, requiring eight repairs and assembly, severely impacting grinding efficiency and production schedules.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be considered to fall within the scope of protection of the present invention.
