A new abrasive disc cutter head structure

Abstract

This utility model provides a novel grinding disc cutter head structure, relating to the field of grinding tool technology. It includes a grinding mechanism comprising a cutting tool with a slanted groove at one end and an annular groove at the other. A filter screen is installed at one end of the annular groove, and a liquid spray port is located at the end of the cutting tool away from the annular groove. The slanted groove and annular groove on the cutting tool end face ensure that grinding debris and dust generated during rotation are promptly discharged from the working area, preventing repeated grinding and accumulation of debris and ensuring the grinding quality of the workpiece surface. A cooling mechanism is added, allowing coolant to be directly delivered to the grinding contact area between the cutting tool and the workpiece, effectively reducing the working temperature of the cutting head during high-speed grinding and extending the tool's service life. Simultaneously, the filter screen inside the annular groove effectively intercepts debris from entering the cooling channel, ensuring the long-term stable operation of the cooling system and reducing maintenance frequency and costs.

Description

Technical Field

[0001] This utility model relates to the field of grinding tools, and in particular to a novel grinding disc head structure. Background Technology

[0002] The grinding disc cutter head is a key actuating component installed on the rotor of various grinding, milling, and polishing equipment.

[0003] Existing grinding discs generally suffer from poor cooling, reliance on external spraying leading to severe high-temperature wear, and short lifespan. The chip removal groove design is often insufficient, which easily leads to the accumulation and blockage of dust and debris generated during grinding, requiring repeated grinding, reducing grinding efficiency, and easily leaving scratches on the treated surface. This results in low work efficiency, difficulty in controlling product quality, and troublesome maintenance. Utility Model Content

[0006] In a preferred embodiment, the cooling mechanism includes a fixed infusion tray with a sliding groove inside. A sealing O-ring is provided at the end of the sliding groove near the cutter. An injection port is provided at the end of the fixed infusion tray away from the cutter, and a locking hole is provided at the end of the fixed infusion tray away from the mounting hole.

[0007] In a preferred embodiment, the cutting tool has twenty oblique grooves arranged in a circular, equidistant array.

[0008] In a preferred embodiment, the spray nozzles are located at the intersection of the inclined groove and the annular groove, and the spray nozzles are arranged in a circular equidistant array.

[0009] In a preferred embodiment, the end of the cutter furthest from the filter screen is disposed inside the sliding groove.

[0010] In a preferred embodiment, the fixed infusion tray has six locking holes at the end away from the mounting hole, and the locking holes are arranged in a circular equidistant array.

[0011] In a preferred embodiment, two sealing O-rings are provided at one end of the sliding groove near the cutter, and the sealing O-rings are symmetrically distributed about the liquid outlet.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention features inclined and annular grooves on the end face of the cutting tool, ensuring that chips and dust generated during grinding are promptly discharged from the working area, preventing repeated grinding and accumulation of chips, and guaranteeing the grinding quality of the workpiece surface. A cooling mechanism is added, allowing coolant to be directly delivered to the grinding contact area between the cutting tool and the workpiece, effectively reducing the working temperature of the cutting head during high-speed grinding and extending the tool's service life. Simultaneously, a filter screen is installed inside the annular groove, effectively intercepting chips from entering the cooling channel, ensuring the long-term stable operation of the cooling system, and reducing maintenance frequency and costs.
