Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, specifically relating to a grinding wheel structure that prevents breakage. Background Technology

[0002] The grinding wheel is a core tool in industrial grinding, using its high-speed rotating rough surface to grind, cut, or polish workpieces. Its structure has three key parts: the working layer, the outer layer that directly contacts the workpiece, consists of abrasive, bonding agent, and micropores, and performs the cutting function; the matrix, the inner supporting skeleton, is responsible for fixing the working layer, transmitting grinding force, and ensuring the rigidity of the grinding wheel; and the mounting hole, located in the center, is the interface between the grinding wheel and the machine tool spindle, requiring a matching spindle diameter to ensure stable rotation. The coordination of these three components determines the efficiency and safety of the grinding wheel.

[0003] The connection between the working layer and the substrate of existing grinding wheels often suffers from a weakness in strength: the two rely heavily on bonding agents or sintering for adhesion. Under the influence of centrifugal force from high-speed rotation, grinding impact, and thermal stress, stress concentration easily occurs at the interface. This is especially true for thin-bladed or large-diameter grinding wheels, where the interface between the working layer and the substrate is prone to fracture due to adhesive failure, or even the working layer detaching from the substrate. This reduces grinding efficiency and poses safety hazards. Therefore, a new grinding wheel structure needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a fracture-resistant grinding wheel structure to solve the problem mentioned in the background art that the connection surface between the working layer and the substrate of the existing grinding wheel structure has general strength and is prone to fracture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant grinding wheel structure, comprising...

[0006] Matrix;

[0007] The working layer includes the main body fixed to the outside of the substrate;

[0008] The reinforcement components include slots that are opened around the outer edge of the base, connecting grooves that are opened around the inner side of the main body and correspond one-to-one with the slots, and a reinforcement rod that is fixedly disposed between the slots and the connecting grooves;

[0009] The reinforcing rod includes a rod body, the inner end of which is fixed inside the slot, and the outer end extends out of the slot and is fixedly connected to the connecting groove.

[0010] Preferably, the reinforcing rod further includes protrusions, which are symmetrically fixed on both sides of the outer end of the rod and can engage with the inner wall of the connecting groove.

[0011] Preferably, the number of slots, reinforcing rods, and connecting grooves are all six, and they are evenly distributed around the center of the base.

[0012] Preferably, the reinforcing component further includes a glass fiber mesh strip disposed between the bonding surfaces of the substrate and the working layer.

[0013] Preferably, the working layer further includes chip removal and heat dissipation grooves, which are formed around the surface of the main body.

[0014] Preferably, the chip removal and heat dissipation groove surrounds the outside of the connecting groove, and chip removal and heat dissipation grooves are provided on both sides of the main body.

[0015] Preferably, the substrate has a mounting hole at its center, and the mounting hole is circular.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a reinforcing component between the base and the working layer, and through the physical interlocking between the reinforcing rod and the connecting groove, the connection between the base and the working layer is reinforced, preventing the grinding wheel structure from breaking due to excessive load on the joint surface during high rotation. This enhances the overall strength of the grinding wheel structure and provides good anti-breakage capability. Attached Figure Description
