Abstract
Description
Technical Field
[0001] This utility model relates to the field of abrasive technology, specifically a diamond steel-aluminum composite matrix grinding wheel. Background Technology
[0002] Diamond grinding wheels are superhard grinding tools formed by bonding diamond abrasive as the core material and using a binder. They are widely used in the processing of hard and brittle materials and cemented carbide. Diamond grinding wheels differ from ordinary abrasive grinding wheels in structure. They are generally composed of a diamond abrasive layer, a transition layer and a matrix.
[0003] Chinese utility model patent CN220348147U, published on January 16, 2024, discloses a grinding wheel made of carbon fiber matrix composite material, comprising a metal matrix, a carbon fiber matrix disposed on the upper end face of the metal matrix, a metal ring disposed on the outer surface of the carbon fiber matrix, and an abrasive layer disposed on the outer surface of the metal ring. This utility model relates to the field of grinding wheel technology. This carbon fiber matrix composite material grinding wheel features light weight, low moment of inertia, low motor input load, and rapid linear speed increase, making it suitable for grinding high-precision products. By optimizing the grinding wheel matrix structure and adding a metal ring, the heat conduction area of the abrasive is increased and the conduction efficiency of the cutting fluid is improved. Furthermore, the metal ring, located between the abrasive and the carbon fiber matrix, increases the moment of inertia to ensure the stability of the carbon fiber grinding wheel, increases the moment of inertia of the matrix, and reduces or avoids elastic deformation of the matrix during grinding. This grinding wheel possesses the characteristics of light weight, high thermal conductivity, and high modulus, combining the performance of a metal grinding wheel and a pure carbon fiber grinding wheel, making it suitable for machining shaft products with large grinding volumes.
[0004] However, the above-mentioned disclosed solutions have the following shortcomings: Although the substrates made of materials other than steel and aluminum in the existing technology achieve the purpose of being lightweight, their structural strength is lower than that of diamond metal bonded grinding wheels, and diamond metal bonded grinding wheels cannot be made. This results in the disadvantage of low structural strength despite the advantage of being lightweight. Utility Model Content
[0005] The purpose of this invention is to solve the technical problem that existing substrates made of materials other than steel and aluminum, while achieving the goal of being lightweight, have lower structural strength than diamond metal bonded grinding wheels and cannot be made using diamond metal bonded grinding wheels, resulting in the disadvantage of low structural strength despite the advantages of being lightweight. The invention provides a diamond steel-aluminum composite substrate grinding wheel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] The present invention discloses a diamond steel-aluminum composite matrix grinding wheel, comprising a first matrix; a rotating groove is symmetrically formed on the first matrix; a rotating block is inserted into the rotating groove; a second matrix is fixedly connected to the rotating block; fasteners are threadedly connected to the second matrix and the first matrix; and multiple grinding blocks are sintered on the upper surface of the second matrix.
[0008] Furthermore, the first substrate has through holes.
[0009] Furthermore, a stepped groove is formed on the first substrate.
[0010] The diamond steel-aluminum composite matrix grinding wheel provided by this utility model has the following beneficial effects:
[0011] 1. This utility model uses a second base made of steel, which can be sintered and fixed with multiple grinding blocks at a temperature above 750°C. Then, the second base and the first base made of aluminum are connected and fixed by fasteners. This achieves high-temperature sintering of diamond and reduces the overall weight. The loading and unloading operation is convenient, quick and safe for workers, and it causes less damage to the grinding machine spindle, which can reduce the driving power of the grinding machine.
[0012] 2. The second substrate of this utility model is made of steel, which allows it to withstand sintering at higher temperatures and enables the sintering of metal binders to fix the grinding blocks. This results in high connection strength for the grinding blocks made of diamond material, allowing them to grind under greater pressure. Attached Figure Description

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.
[0022] Please see Figure 1-4 As shown, a diamond steel-aluminum composite matrix grinding wheel includes a first matrix 1; a rotating groove 5 is symmetrically formed on the first matrix 1; a rotating block 9 is inserted into the rotating groove 5; a second matrix 6 is fixedly connected to the rotating block 9; fasteners 7 are threadedly connected to the second matrix 6 and the first matrix 1; multiple grinding blocks 8 are sintered on the upper surface of the second matrix 6. The second matrix 6, made of steel, can be sintered and fixed with the multiple grinding blocks 8 at a temperature above 750°C. Then, the second matrix 6 and the first matrix 1, made of aluminum, are connected and fixed by the fasteners 7. This achieves high-temperature sintering of diamond and reduces the overall weight. The loading and unloading operation is convenient, quick, and safe for workers, and it causes less damage to the grinding machine spindle, thus reducing the drive power of the grinding machine.
[0023] The first substrate 1 has a through hole 3. The through hole 3 can reduce the weight of the first substrate 1 and at the same time form a clearance space for installation on the spindle of the grinding machine.
[0024] The first substrate 1 has a stepped groove 2. The stepped groove 2 can reduce the weight of the first substrate 1 and create clearance space for installation on the spindle of the grinding machine.
[0025] Multiple mounting holes 4 are provided in the stepped groove 2. The groove can be stably and accurately fixed to the main shaft of the grinding machine by using multiple mounting holes 4 and multiple bolts.
[0026] The first substrate 1 is made of aluminum, which makes the overall weight of the first substrate 1 low, making it easy, quick and safe for workers to load and unload, and causing less damage to the grinding machine spindle, thus reducing the drive power of the grinding machine.
[0027] The second substrate 6 is made of steel, which allows it to withstand sintering at higher temperatures. This enables the sintering of the metal binder to fix the grinding block 8, resulting in high connection strength for the diamond grinding block 8, which can be ground under greater pressure.
