Abstract
The utility model discloses a replaceable polishing head. The replaceable polishing head comprises an installation casing pipe. The installation casing pipe is provided with a plurality of installation grooves used for installation of belt abrasive paper, the length direction of the installation grooves extends in the axial direction of the installation casing pipe, and the installation grooves are uniformly distributed in the circumferential direction of the installation casing pipe. A folding edge is arranged on the end portion of each piece of the belt abrasive paper, and the folding edges are arranged inside the installation casing pipe. A locating casing pipe used for fixing the folding edges and the installation casing pipe is arranged inside the installation casing pipe and provided with an installation hole used for being connected with a drive shaft of a motor. When the belt abrasive paper is abraded, the locating casing pipe can be taken out from the installation casing pipe, new belt abrasive paper can be installed inside the installation grooves, then the new belt abrasive paper and the installation casing pipe are located through the locating casing pipe, and the polishing head can be used continuously. Thus, the service life of the polishing head is prolonged, the production cost is lowered greatly, and the structure is simple.
Description
Technical field
The utility model relates to a kind of replaceable rubbing head.
Background technology
The rubbing head that generally uses at present, usually sand paper being directly fixed on the enterprising enforcement of mounting sleeve by specific technique uses, after the sand paper wearing and tearing, the rubbing head that need to more renew, during polishing, the wear extent of sand paper is very large, and the service life of each rubbing head is extremely short, then so that production cost greatly improve.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of replaceable rubbing head is provided, and is simple in structure, and the sand paper that only needs to change wearing and tearing can continue to use, and saves production cost, and service life is longer.
For achieving the above object, the technical solution of the utility model is a kind of replaceable rubbing head of design, comprise mounting sleeve, offer a plurality of length directions on the described mounting sleeve along its axially extended mounting groove be used to banded sand paper is installed, a plurality of described mounting grooves circumferentially evenly distribute along described mounting sleeve, the end of each described banded sand paper has flanging, described flanging is positioned at described mounting sleeve, be provided with in the described mounting sleeve for the locating sleeve that described flanging and described mounting sleeve is fixing, offer on the described locating sleeve for the installing hole that connects motor driving shaft.
As preferably, have keyway in the described installing hole, the key on described keyway and the described driving shaft is suitable.Be convenient to be connected with driving shaft.
As preferably, described locating sleeve is tapered.Be convenient to locating sleeve flanging and mounting sleeve are fitted tightly, avoid banded sand paper and mounting sleeve to be separated.
As preferably, the length of described banded sand paper is greater than the outer arc length between adjacent two described mounting grooves.The outer surface that guarantees mounting sleeve is all wrapped up by banded sand paper, then guarantees quality of finish, avoids Lou throwing phenomenon and occurs.
Advantage of the present utility model and beneficial effect are: after banded sand paper wearing and tearing, locating sleeve can be taken out in mounting sleeve, in mounting groove, load onto new banded sand paper, by locating sleeve banded sand paper and mounting sleeve are located again, can continue to use, prolong the service life of rubbing head, greatly reduced production cost, and simple in structure.
Description of drawings
Fig. 1 is side view of the present utility model;
Fig. 2 is front view of the present utility model.
Among the figure: 1, mounting sleeve; 2, banded sand paper; 3, mounting groove; 4, flanging; 5, locating sleeve; 6, installing hole; 7, keyway.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Such as Fig. 1, shown in Figure 2, a kind of replaceable rubbing head, comprise mounting sleeve 1, offer eight length directions on the described mounting sleeve 1 along its axially extended mounting groove 3 be used to banded sand paper 2 is installed, eight described mounting grooves 3 circumferentially evenly distributing along described mounting sleeve 1, the end of each described banded sand paper 2 has flanging 4, described flanging 4 is positioned at described mounting sleeve 1, be provided with the locating sleeve 5 of fixing for described flanging 4 and described mounting sleeve 1 in the described mounting sleeve 1, offer on the described locating sleeve 5 for the installing hole 6 that connects motor driving shaft.Wherein the quantity of mounting groove 3 is not limit, and namely the quantity of banded sand paper 2 is not limited to eight.
As shown in Figure 1, have keyway 7 in the described installing hole 6, described keyway 7 is suitable with the key on the described driving shaft.Without diagram, described locating sleeve 5 is tapered.
As shown in Figure 1, the length of described banded sand paper 2 is greater than the outer arc length between adjacent two described mounting grooves 3.The outer surface that guarantees mounting sleeve 1 is all wrapped up by banded sand paper 2, then guarantees quality of finish, avoids Lou throwing phenomenon and occurs.
Banded sand paper 2 installation processes: at first banded sand paper 2 one ends are inserted in the corresponding mounting groove 3, carry out flanging 4, then at mounting sleeve 1 interior insertion locating sleeve 5, by the extruding force of mounting sleeve 1 between locating sleeve 5 that flanging 4 is fixing with mounting sleeve 1.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
