Abstract
A combined type floor grinding head structure comprises a disc, wherein a plurality of fan-shaped plastic blocks are arranged on the lower lateral surface of the disc and are arranged into two or more concentric round rings, radial clamping grooves are formed in the lower lateral surface of the round disc, an upwards protruding radial clamping pin is arranged on the upper lateral surface of any one fan-shaped plastic block and clamped in the corresponding radial clamping groove, at least two downwards protruding round pipes are arranged on the lower lateral surface of any one fan-shaped plastic block, an abrasive block is fixedly arranged in any one round pipe, and the lower end of each abrasive block protrudes out of the lower end of the corresponding round pipe and is conical or a spherical surface. According to the combined type floor grinding head structure, the multiple fan-shaped plastic blocks are arranged on the bottom surface of the disc to form a grinding head and are connected with the disc through the clamping pins and the clamping grooves. Under the condition of loss failure of the abrasive blocks of part of the fan-shaped plastic blocks, the whole grinding head can be normally used only by replacing the abraded fan-shaped plastic blocks with new fan-shaped plastic blocks of the corresponding shapes.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to cutting element, particularly floor grinding head, and concrete is a kind of combined floor board grinding head structure.
Background technology:
Floor sander carries out grinding process by grinding head to wood floors.In prior art, grinding head comprises a disk, is distributed with the abrasive material piece of a plurality of projections on disk.Due in bruting process, the extent of deterioration of each abrasive material piece is all inconsistent, and therefore, the more loss of part abrasive material piece will cause whole grinding head to be scrapped, and has increased use cost.
Summary of the invention:
The purpose of this utility model is to provide a kind of combined floor board grinding head structure, the technical problem that the very fast loss that described this combined floor board grinding head structure will solve part abrasive material piece in prior art causes whole grinding head to be scrapped.
This combined floor board grinding head structure of the present utility model, comprise a disk, wherein, in the downside of described disk, be provided with a plurality of fan-shaped unit of plastics, described fan-shaped unit of plastic is arranged in the donut of more than two number, donut described in any one is all concentric with disk, in the downside of disk, be provided with radially draw-in groove, in the upper side of the fan-shaped unit of plastic described in any one, be provided with the radially card base raising up, described radially card base snaps in described radially draw-in groove, in the downside of any one fan-shaped unit of plastic, be provided with at least two pipes that protrude downwards, in pipe described in any one, be all fixedly installed an abrasive material piece, the lower end of described abrasive material piece protrudes from the lower end of pipe.
Further, the tapered or sphere in the lower end of abrasive material piece.
Further, the both sides of the upper side of fan-shaped unit of plastic are provided with the radially card base raising up, two radially the distance between the upper end of card base be less than the width of the upper side of fan-shaped unit of plastic.
Operation principle of the present utility model is: a plurality of fan-shaped unit of plastics are arranged in the bottom surface of disk, is combined into a grinding head.Fan-shaped unit of plastic is connected with disk with draw-in groove by card base.In the fan-shaped unit of plastic of part, abrasive material piece loss failure in the situation that, the new fan-shaped unit of plastic that only need to replace correspondingly-shaped just can make whole grinding head normally use.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes a plurality of fan-shaped unit of plastics to be arranged in the bottom surface of disk, is combined into a grinding head, and fan-shaped unit of plastic is connected with disk with draw-in groove by card base.In the fan-shaped unit of plastic of part, abrasive material piece loss failure in the situation that, the new fan-shaped unit of plastic that only need to replace correspondingly-shaped just can make whole grinding head normally use.
Accompanying drawing explanation:
Fig. 1 is the elevational schematic view of a fan-shaped unit of plastic in combined floor board grinding head structure of the present utility model.
Fig. 2 is the side direction structural representation of a fan-shaped unit of plastic of combined floor board grinding head structure of the present utility model.
Fig. 3 is the structural representation of looking up of combined floor board grinding head structure of the present utility model.
The specific embodiment:
Embodiment 1:
As Fig. 1, shown in Fig. 2 and Fig. 3, combined floor board grinding head structure of the present utility model, comprise a disk 1, wherein, in the downside of described disk 1, be provided with a plurality of fan-shaped unit of plastics 2, described fan-shaped unit of plastic 2 is arranged in the donut of more than two number, donut described in any one is all concentric with disk 1, in the downside of disk 1, be provided with radially draw-in groove (not shown), in the upper side of the fan-shaped unit of plastic 2 described in any one, be provided with the radially card base 3 raising up, described radially card base 3 snaps in described radially draw-in groove, in the downside of any one fan-shaped unit of plastic 2, be provided with at least two pipes 4 that protrude downwards, in pipe 4 described in any one, be all fixedly installed an abrasive material piece 5, the lower end of described abrasive material piece 5 protrudes from the lower end of pipe 4.
Further, the tapered or sphere in the lower end of abrasive material piece 5.
Further, the both sides of the upper side of fan-shaped unit of plastic 2 be provided with 3, two of the radially card bases that raise up radially the distance between the upper end of card base 3 be less than the width of the upper side of fan-shaped unit of plastic 2.
The operation principle of the present embodiment is: a plurality of fan-shaped unit of plastics 2 are arranged in the bottom surface of disk 1, are combined into a grinding head.Fan-shaped unit of plastic 2 is connected with disk 1 with draw-in groove by card base.In the fan-shaped unit of plastic 2 of part, abrasive material piece 5 loss failure in the situation that, the new fan-shaped unit of plastic 2 that only need to replace correspondingly-shaped just can make whole grinding head normally use.
