[0002] Diamond grinding blocks are used for grinding stone. They are primarily composed of small diamond particles bonded together with resin. Existing diamond grinding blocks typically use a cast iron base, with the diamond grinding block mounted on the cast iron block to grind stone or other raw materials. In actual use, diamond grinding blocks are unable to achieve hole enlargement or grinding of tapered holes, nor can they effectively grind holes of varying sizes and depths. Furthermore, existing diamond grinding blocks generate heat during the grinding process. Excessive heat concentration can shorten the life of the diamond grinding block or burn the raw material being ground. Utility Model Content

[0005] Through the above technical solution, the main rod is installed on the driving mechanism of the grinding equipment, such as on an electric hand drill, or on the driving source of a CNC machine tool. According to the angle of the inner hole to be ground as needed, the first connecting block is slid on the main rod. At this time, the mounting rod and the connecting rod form a certain inclination. After the grinding block has a certain angle, the knob is turned to fix the first connecting block. In this way, the angle formed by the grinding block is fixed. Afterwards, the main rod drives the mounting rod through the second connecting block to make the grinding block grind the material. Since the mounting rod is rotating, cold air enters the heat dissipation hole at this time, and the hot air in the heat dissipation cavity is blown away. At the same time, the heat conductive plate can conduct the heat of the grinding block to the heat dissipation cavity, and the cycle is repeated to achieve cooling of the grinding block, protect the grinding block from high temperature, and extend its service life.

[0009] As a further description of the above technical solution:

[0010] The heat dissipation holes are arranged in the middle of both sides of the heat conducting plate;

[0011] Through the above technical solution, when the mounting rod rotates to drive the grinding block to grind, cold air enters the heat dissipation hole and causes the hot air in the heat dissipation cavity to flow out, thereby cooling the grinding block and preventing high temperature operation from affecting the grinding of raw materials or affecting the service life of the grinding block.

[0012] As a further description of the above technical solution:

[0013] A connecting sleeve is fixedly connected to a side of the first connecting block away from the second connecting block, a fixing portion is provided at one end of the connecting sleeve away from the first connecting block, a knob is threadedly connected to the outer periphery of the connecting sleeve, a clamping portion is provided on the inner side of the knob, and the clamping portion and the fixing portion are provided on the same side;

[0014] Through the above technical solution, the first connecting block reciprocates back and forth, so that the mounting rod drives the grinding blocks to open at an angle with each other, thereby adjusting the grinding angle of the grinding tool. In this way, by turning the knob, the first fixed block is fixed on the main rod, which is convenient for subsequent grinding of stone, etc.

[0015] As a further description of the above technical solution:

[0016] The angle between the clamping portion and the horizontal plane is an obtuse angle, and the angle between the fixing portion and the horizontal plane is an acute angle;

[0017] Through the above technical solution, the clamping portion can realize the tilting of the fixing portion against the main rod, thereby achieving the fixation of the first connecting block.

[0018] As a further description of the above technical solution:

[0019] Each of the grinding blocks is provided with an inclined discharge chute;

[0020] Through the above technical solution, the waste produced by the grinding block can enter the discharge chute to achieve the purpose of discharging the waste chips.

[0021] As a further description of the above technical solution:

[0022] The angle between the opening formed by the connecting rod and the mounting rod and the main rod is between 30 and 230 degrees;

[0023] Through the above technical solution, within this angle, the angle formed between the connecting rod and the mounting rod combined with the main rod can form a stable triangular structure, which is convenient for stable grinding of the grinding tool.

[0024] The utility model has the following beneficial effects:

[0025] 1. In the present invention, the first connecting block slides a certain distance on the main rod, so that the connecting rod and the mounting rod form a certain inclination, and the mounting rods form an inclined frustum between each other. In this way, the frustum cone between the grinding blocks can realize the grinding of the inner hole of the raw material to be ground. At the same time, different sizes of cones can be formed between the mounting rods, which can grind inner holes of different sizes.

[0026] 2. In the present invention, the heat conducting plate conducts the heat of the grinding block in the heat dissipation cavity. When the mounting rod rotates, cold air enters the heat dissipation hole, causing the hot air in the heat dissipation cavity to flow out, thereby achieving heat dissipation of the grinding block and ensuring the life of the grinding block. At the same time, the grinding material will not be burned by high temperature during grinding. BRIEF DESCRIPTION OF THE DRAWINGS
