Abstract

The utility model relates to the grinding-head of a grinding machine, which is mainly used to grind walls, furniture, and various painting surfaces. The grinding head is composed of a grinding disk, a barrel shape grinding component, a pad, and an elastic ferrule, wherein, the grinding component is composed of a grinding cloth type bottom surface and a grinding cloth barrel loop, and the grinding cloth type bottom surface and the grinding cloth barrel loop are glued together. The grinding component is sleeved on the grinding disk, and the grinding component is tightened on the grinding disk through the elastic ferrule. The structure of the utility model has the advantages that the grinding component is easy to be changed, the working surface of the grinding component is smooth, not easy to be deformed, and not easy to fall off.

Description

Burnishing-head of burnishing machine

The utility model belongs to polishing, polissoir, is a kind of sander bistrique of be used to polish wall, furniture or various paint faces.

In the past polished furniture, wall or various paint faces etc. mostly are manual grinding.Occurred a kind of pneumatic type sander in the market, the bistrique of this sander is made double vibrations, and its grinding head is made up of mill, pad and emery cloth, and its Intermediate gasket is made by the hard rubber material, and pad and emery cloth all are screwed at the mill end face.The inventor uses through reality and finds that there is following problem in this grinding head: 1, the elastic force of pad is excessive, mill is a double vibrations in addition, so it is steady inadequately during work, particularly when polishing wall or some paint face, because of relatively poor by the glacing flatness of buffed surface, so it is bigger to cause this grinding head to be beated, so that can't actually use; 2, because of emery cloth is screwed on mill, so the working time is not long, promptly cause emery cloth loose, be out of shape or come off.

The purpose of this utility model provides steady, the firm sander bistrique of part connection of polishing of a kind of work, and this bistrique is mainly used in polishing wall and various paint face.

The solution that realizes the utility model purpose is: the sander bistrique that is provided comprises a mill, connects firmly pad and emery cloth class polishing part on mill.Its Intermediate gasket adopts the high-density sponge pad; Above-mentioned polishing part is barrel-shaped, and it is made of the bottom surface of emery cloth class and the cloth cylinder coil of knitting that is connected on this bottom surface, and by an elastic collar by lock ring on mill.During use, can carry out polishing work, also can be installed in certainly on the rotating shaft of hand-held rotation facility, on the motor shaft that can be installed in electric hand drill as long as mill is installed on the rotating shaft of hand sander.

Of the present utility model simple in structure owing to adopted the emery cloth class polishing part of barrel shaped structure, and utilize elastic collar with its lock ring on mill, so emery cloth can not come off, be out of shape during work, and remain formation state.After emery cloth lost efficacy, take off elastic collar, promptly replaceable new polishing part, thereby very convenient.This bistrique adopts the high-density sponge pad to place between emery cloth and the mill, and its elastic force is moderate, and has certain shrinkage, and is more steady when not only making polishing wall, furniture, but also some concave surfaces of can polishing.

Below in conjunction with accompanying drawing content of the present utility model is illustrated:

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is one of polishing part structure chart of the present utility model.

Fig. 3 is two of a polishing part structure chart of the present utility model.

As shown in Figure 1: mill 1 is metal or plastic disc, and there is a hole 2 in its central authorities, so that be installed on the rotating shaft 3 of sander.Polishing part 4 is enclosed within the outside of mill 1, between mill and the polishing part sponge pad 5 is arranged, and its thickness is 8～40mm, can decide according to the object of polishing.Lasso 6 adopts annular elastic force strap, and its will polish tube of part 4 encloses part 7 lock rings on mill 1.

The structure of polishing part 4 is as shown in Figure 2: the polishing part is made up of a bottom surface 8 and tube circle 7 two parts.Bottom surface 8 is made of two emery cloths that are bonded together back-to-back 9, and its diameter equals the mill diameter.An end of knitting cloth cylinder coil 7 is bonded between two emery cloths 9, thereby constitute a barrel-shaped polishing part, do the bottom surface if adopt sand paper, then between two sand paper 10, should weave cotton cloth 11 by bonding one deck, so that increase its intensity, its structure adopts two emery cloths or sand paper to do the bottom surface and is convenient to first be bonded in the tube circle on the bottom surface securely as shown in Figure 3; Second but use on the two sides, bottom surface, improves the service life of polishing part, when utilizing this bistrique polishing concave surface, can between mill and polishing part bottom surface, fill up thicker foam-rubber cushion, as long as bistrique is exerted pressure slightly, then strain just takes place in the working face of bistrique, matches with the concave surface of being polished.
