Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, specifically a grinding wheel with a built-in abrasive chip adsorption function. Background Technology

[0002] A grinding wheel, also known as a bonded abrasive, is a type of abrasive tool in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape (mostly circular with a central through-hole) and possess a certain strength. It generally consists of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of a bonded abrasive tool.

[0003] Chinese utility model patent CN220863722U, published on April 30, 2024, discloses a diamond grinding wheel with a cooling structure. The wheel includes a grinding mechanism, a storage mechanism on the rear inner wall of the grinding mechanism, and a diatomaceous earth plate on the rear inner wall of the grinding mechanism. The storage mechanism includes five fixing plates, which are fixedly installed on the rear inner wall of the grinding mechanism. A storage cylinder is fixedly installed between the fixing plates, and a connecting cover is threaded onto the external surface of the storage cylinder. A silicone film is fixedly installed on both the back of the connecting cover and the front of the storage cylinder. A through hole is formed on the outer wall of the storage cylinder. This diamond grinding wheel with a cooling structure, through the storage mechanism and diatomaceous earth plate, effectively stores coolant and uses it during the operation of the diamond grinding wheel, thereby continuously adsorbing and evaporating the heat generated by the diamond grinding wheel, improving heat dissipation efficiency.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing diamond grinding wheels do not have the function of adsorbing and collecting the grinding debris generated during grinding, which causes the grinding debris generated during grinding to enter between the diamond grinding wheel and the workpiece, thereby reducing the grinding accuracy of the diamond grinding wheel. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing diamond grinding wheels do not have the function of adsorbing and collecting grinding debris, which causes the grinding debris to enter between the diamond grinding wheel and the workpiece during the grinding process, thereby reducing the grinding accuracy of the diamond grinding wheel. The invention provides a grinding wheel with a built-in grinding debris adsorption function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a grinding wheel with built-in shavings adsorption function, comprising a base fixed to a grinding machine; a countersunk hole is formed through the cylindrical surface of the base; multiple grinding blocks are fixedly connected to the lower end of the base; multiple fasteners are inserted into the opening of the base; a stepped shaft is threaded onto the outer surface of the fastener; multiple quarter-slots are formed inside the stepped shaft; the stepped shaft is chamfered to align with the quarter-slots; multiple shims are fixedly connected inside the quarter-slots; and water-absorbing blocks are placed on the shims.

[0008] The grinding wheel with built-in chip adsorption function provided by this utility model has the following beneficial effects:

[0009] 1. This utility model aligns the lower surface of the stepped shaft with the lower surface of the grinding block, so that when grinding the workpiece, the lower surface of the stepped shaft is aligned with the workpiece. During the movement of the workpiece, the coolant will enter the quarter-slot along the chamfered slope. The water-absorbing block can absorb a large amount of coolant in the quarter-slot, so that the grinding debris is temporarily stored in the quarter-slot. The grinding debris is periodically removed and the coolant in the water-absorbing block is discharged, so that the grinding debris during the grinding process is collected, reducing the impact on the grinding and thus improving the grinding efficiency and accuracy.

[0010] 2. This utility model can absorb a large amount of coolant in the quarter-cylinder by means of a water-absorbing block, so that the remaining grinding debris is temporarily stored in the quarter-cylinder. The grinding debris and coolant in the water-absorbing block are removed periodically. The water-absorbing block is shaped like a quarter cylinder, so that each one is the same shape. The four water-absorbing blocks can be obtained by cutting one cylinder into four, which makes it convenient to manufacture and replace. Attached Figure Description

[0017] 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.

[0018] 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.

[0019] 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.

[0020] Please see Figure 1-4 As shown, a grinding wheel with built-in abrasive shavings adsorption function includes a base 1 fixed to a grinding machine; a countersunk hole 2 is formed through the cylindrical surface of the base 1; multiple grinding blocks 3 are fixedly connected to the lower end of the base 1; multiple fasteners 4 are inserted into the opening of the base 1; a stepped shaft 5 is threaded onto the outer surface of the fastener 4; multiple quarter-grooves 6 are formed inside the stepped shaft 5; a chamfer 7 is formed on the stepped shaft 5 aligned with the quarter-grooves 6; multiple shims 8 are fixedly connected inside the quarter-grooves 6; a water-absorbing block 9 is placed on the shim 8, and water is absorbed by the lower part of the stepped shaft 5. The lower surface of the surface-aligned grinding block 3 is aligned with the workpiece, so that when grinding the workpiece, the lower surface of the stepped shaft 5 is aligned with the workpiece. During the movement of the workpiece, the coolant will enter the quarter-groove 6 along the chamfered slope 7. The water-absorbing block 9 can absorb a large amount of coolant in the quarter-groove 6, so that the remaining grinding debris is temporarily stored in the quarter-groove 6. The grinding debris is periodically removed and the coolant in the water-absorbing block 9 is discharged, so that the grinding debris during the grinding process is collected, reducing the impact on the grinding, thereby improving the grinding efficiency and accuracy.

[0021] The water-absorbing block 9 is made of water-absorbing material; the water-absorbing block 9 is a quarter cylinder. The water-absorbing block 9 can absorb a large amount of coolant in the quarter-cylinder 6, so that the remaining grinding debris is temporarily stored in the quarter-cylinder 6. The grinding debris is removed and the coolant in the water-absorbing block 9 is drained periodically. The quarter-cylinder shape of the water-absorbing block 9 makes each one the same shape. Four water-absorbing blocks 9 can be obtained by cutting one cylinder into four, which makes it convenient to manufacture and replace.

[0022] The stepped shaft 5 is made of plastic; the lower surface of the stepped shaft 5 is flush with the lower surface of the grinding block 3, so that it can come into contact with the coolant and grinding debris. As the workpiece moves, the coolant and grinding debris will enter the quarter-shaped groove 6 along the inclined chamfer 7, and the coolant will be absorbed by the water absorption block 9. Then the remaining grinding debris will be stored in the quarter-shaped groove 6. The grinding debris and coolant in the water absorption block 9 will be removed periodically.

[0023] The upper surface of the raised plate 8 is flush with the highest point of the chamfer 7, so that the coolant and wear debris can enter the quarter tank 6 with low resistance during the movement with the chamfer 7. Then the coolant is absorbed by the water absorption block 9, and the wear debris is left in the quarter tank 6. The wear debris is removed and the coolant is drained from the water absorption block 9 periodically.

[0024] A baffle plate 10 is fixed to the corresponding water-absorbing block 9 in the quarter-slot 6. The baffle plate 10 restricts the displacement of the water-absorbing block 9, so that the water-absorbing block 9 can only be put in and taken out when it deforms and shrinks in volume under the action of external force. This ensures that the coolant and grinding debris entering the quarter-slot 6 can remain stable and immobile during the rotation of the grinding machine spindle.

[0025] The baffle plate 10 is a quarter-circle arc shape, which allows it to precisely fit the outer surface of the absorbent block 9 for positioning, so that it remains stationary during rotation. This allows it to absorb the cutting fluid raised below, and the grinding debris is left in the quarter-slot 6 for collection.
