Description

Technical Field

[0001] The utility model relates to the technical field of grinding brush filaments, in particular to a fixing disc assembly for grinding brush filaments with a positioning structure. Background Art

[0002] The brush filaments on the existing grinding brushes used for stone or ceramic processing are generally composed of multiple bundles of brush filaments evenly dispersed on the grinding brush base. The grinding brush is fixed on the rotating grinding head, and the high-speed rotation is used to make the grinding brush contact with the surface of the stone or ceramic to play a polishing and grinding role. In order to reduce the temperature generated by friction and increase the smoothness of grinding, water is generally added during grinding.

[0003] When grinding a target with an abrasive brush, the debris generated by friction will fly everywhere, which can easily affect people.

[0004] Therefore, it is necessary to propose a fixed disc assembly for grinding brush filaments with a positioning structure to solve the above problems. Utility Model Content

[0007] Preferably, two side connecting plates are fixed to the outer side of the grinding fixed plate, electric push rods are fixed to the bottom ends of the two side connecting plates, connecting blocks are fixed to the bottom ends of the two electric push rods, arc-shaped protective plates are fixed to the bottom ends of the two connecting blocks, and the opposite sides of the two arc-shaped protective plates are slidably fitted to the outer side of the grinding fixed plate, and the two arc-shaped protective plates are combined into a circle.

[0008] Preferably, sponges are fixed on opposite sides of the two arc-shaped protective plates, inner cavities are opened inside the two arc-shaped protective plates, multiple leakage holes are opened on the sides where the two arc-shaped protective plates and the corresponding sponges are attached, and the multiple leakage holes are connected to the corresponding inner cavities, and a connecting shaft is fixed on the top of the grinding fixed plate.

[0009] Preferably, an injection port is provided on one side of the top end of the two arc-shaped protection plates, and the two injection ports are respectively connected to the corresponding inner cavities.

[0010] Preferably, the plurality of positioning and mounting grooves and the protective shell are all configured to be cylindrical.

[0011] Preferably, an embedded hole is formed on one side opposite to the multiple electromagnets and the corresponding permanent magnets, and an elastic rope is fixed between the two embedded holes.

[0012] Preferably, the height and thickness of the two arc-shaped protection plates are consistent.

[0013] The technical effects and advantages of the utility model are as follows: when grinding, the electric push rod can be used to drive the corresponding arc-shaped protection plate to descend, thereby blocking the outer sides of multiple grinding wire bundles, preventing debris generated during grinding from splashing, and playing a blocking and intercepting role. At the same time, water can be injected into the injection port, and the water will be discharged to the sponge through the leakage hole. When the arc-shaped protection plate moves up and down through the electric push rod, the sponge will wipe the outer side of the grinding fixed disk during the movement, preventing waste water and debris generated by grinding from adhering to the outer side of the grinding fixed disk.

[0014] The protective shell can be directly inserted into the corresponding positioning and mounting groove. Since the positioning and mounting groove and the protective shell have the same shape, they can be easily positioned and installed. At the same time, the electromagnet in the positioning and mounting groove is energized to generate magnetic force to adsorb the permanent magnet on the top of the protective shell, thereby completing the positioning and fixed connection, which is simple and convenient.

[0015] When the grinding wire bundle is used for a period of time, it will produce a certain amount of wear. At this time, by changing the magnetic direction of the electromagnet, the electromagnet and the permanent magnet repel each other. The repulsive force can make the protective shell drive the grinding wire bundle to move downward, ensuring that the bottom end of the grinding wire bundle is always in contact with the target, thereby improving the utilization rate of the grinding wire bundle.
