Detailed description of the invention

The utility model has come out with a kind of sanding device base pad of cost savings, and has the sanding device of this base pad.Now be described with instantiation.

With reference to shown in Fig. 1, the base plate 3 that sander 1 comprises housing 2 and is positioned at below housing 2, the bottom surface of base plate is mounted with base pad 4.Enclosure interior has drive unit 5 and transmission device 6, and drive unit 5 is connected with base plate 3 by transmission device 6, and transmits motion on base plate 3.

With reference to shown in Fig. 2, Fig. 2 is the schematic front view of base pad in case before first, and in figure, the shape of base pad is triangle, and three of triangle bottom plate pad 4 ' drift angles are respectively A ', B ', C '.Triangle bottom plate pad 4 ' is surrounded by a closed outer rim contour C1 ', and outer rim contour C1 ' is joined end to end formed by three sideline A ' B ', B ' C ', C ' A ' of base pad 4 '.The triangle regional area S ' roughly the same with base pad shape is respectively equipped with at three drift angle places of triangle bottom plate pad 4 ', each regional area S ' only accounts for the partial-length in corresponding sideline with the intersection in corresponding sideline, and the wearability of regional area S ' is greater than the wearability of other regions Q '.

With reference to shown in Fig. 3, Fig. 3 is the schematic front view of base pad in case before second, with first before in case the difference of base pad be, the base pad shape before second in case is quadrangle.Four drift angle places of quadrangular bottom plate pad 4 ' are respectively equipped with the quadrangle regional area S ' roughly the same with base pad shape in figure 3, and each regional area S ' only accounts for the partial-length in corresponding sideline with the intersection in corresponding base pad sideline.

In front case, the regional area of each for base pad top corner portion is made the material that other regions are more wear-resisting relatively, mainly be applicable to need frequent use in the corner operation operating mode of the top corner portion of base pad, but the design of front case can not solve the problem that need frequently use the operation operating mode of base pad outer portions to run into.

Base pad in front case is mainly suitable for needs the frequent top corner portion that uses to operate, and can not be suitable for and need frequently use outer portions to operate, its main cause is that regional area S ' is only the partial-length in sideline with the intersection in each sideline, instead of whole length in sideline.

For the deficiency existed in front case design, the utility model improves sanding device base pad.Regional area is expanded to the whole piece outer portions of base pad from each top corner portion of base pad, not only frequently can use the top corner portion of sanding device base pad, also can the length of side part of relieved use base pad, therefore, extend the applying working condition of sanding device base pad, can further improve the efficiency of polishing.

With reference to shown in Fig. 4, it is the schematic front view of the base pad of the utility model embodiment one.In figure, the shape of base pad 4 is triangle, and three drift angles of triangle bottom plate pad 4 are respectively A, B, C.Base pad 4 is surrounded by a closed outer rim contour C1, and outer rim contour C1 is joined end to end by three sidelines AB, BC, CA of base pad 4 and forms.Figure intermediate cam shape base pad 4 comprises first area Q and second area S.End to end three sidelines AB, BC, CA of triangle bottom plate pad 4 can be obtained new leg-of-mutton end to end three sidelines A1B1, B1C1, C1A1 to the center development length d of base pad simultaneously, elongated area between triangle A1B1C1 outside and triangle ABC inside is the second area S of triangle bottom plate pad, and first area Q is positioned at the inside of second area S.Second area S has outline line, and outline line comprises outer contour E1 and inner outline E2, can be found by figure, outer contour E1 is exactly end to end three sidelines of triangle bottom plate pad 4, be outer rim contour C1, inner outline E2 is exactly end to end three sidelines of new triangle A1B1C1, and outer contour E1 and inner outline E2 is almost parallel, and the development length d between outer contour E1 and inner outline E2, correspondingly can adjust according to different duty requirements.

In addition, in the process extended to inner outline E2 at outer contour E1 here, also can be that Unequal distance extends, extending the inner outline E2 obtained can be straight line, and can be curve, also can be broken line.

In the present embodiment, the outer contour E1 of the second area S of base pad overlaps with outer rim contour C1, and namely the outline line of base pad comprises the sideline of three base pad.

For such base pad, annexation between first area Q and second area S, the utility model comes out with the problem that two kinds of technical schemes solve base pad waste of material: a kind of is that the second area of base pad is designed to dismountable form; Another kind is that base pad second area is selected the material more wear-resisting than first area, will illustrate the implementation of each technical scheme below.

The technical scheme one that the present embodiment openly provides is: be fixedly installed by the base plate of relative for the first area of base pad sanding device, removably arranged second area opposing first regions.According to the characteristic that the first area in the technical program and second area have, first area also can be called FX, and second area also can be called zone of action.

The zone of action of base pad is made relative FX detachable after, when the zone of action of base pad is because using frequently serious wear, but when FX still can continue to use, only can change the zone of action of base pad, and do not need the FX changing base pad, doing so avoids and change monoblock base pad and the unnecessary waste that causes, saved cost.

The FX of base pad and the zone of action of base pad all can be connected with the base plate of sanding device with reliable bonding method, wherein, the zone of action of base pad and the FX of base pad can't link together, when carrying out dismounting and change to the zone of action of base pad, the connection of FX and base plate can't be affected.When the zone of action serious wear of base pad, only need tear the zone of action of base pad, zone of action is separated with base plate, and then again change the base pad part identical with the zone of action shape size pulled down, frosted work can be carried out jointly with former base pad FX in the base pad zone of action after replacing.

Wherein, the zone of action of the base pad of sanding device can be identical with the material of normal areas, can be different.

The interchangeable technical scheme of the another kind that the present embodiment openly provides is: base pad comprises outer rim sideline and working region, working region comprises first area and second area, wherein the wearability of second area material is set to the wearability being greater than first area material.According to the characteristic that the first area in the technical program and second area have, first area also can be called normal areas, and second area also can be called wear areas.

The frequency of utilization of base pad second area is higher, but the frequency of utilization of the first area of base pad is lower, and second area is made wear areas, and second area makes normal areas, and the service life in two regions can be made substantially identical.That is, when the first area life-span that wear-resisting frequency of utilization is higher totally needs to change base pad, the second area that not wear-resisting frequency of utilization is not high also can not use substantially, avoid normal areas when original base pad is changed and can also continue situation about using, avoid unnecessary waste, about cost.

For such base pad, from the relation formed between first area Q and the material of second area S, the wearability of the second area of the base pad of sanding device is higher than second area.

The second area material of base pad is made up by cure process of first area material.

When using the material of rubber-like to carry out base pad manufacture, certain vulcanizing treatment can be carried out to the second area of base pad, the phosphorus content of base pad second area material is made to be greater than the phosphorus content of first area material, thus making the hardness of second area material be greater than the hardness of first area material, the wearability that so just can realize the wear areas of base pad is greater than the wearability of normal areas.

Or also can add wearing layer on the working surface of second area, to improve the local wearability of second area.

The second area realizing base pad is different from the material of first area, and the wearability of second area higher than the simplest method in first area is: only need the material that selection two kinds of wearabilities are different, using the material as first area lower for wearability, the material as second area that wearability is higher.Such as, if the first area of base pad is set to sponge kind or foam class material, so the second area of base pad is just set to rubber-like or felts material, if the first area of base pad is set to felts material, so the second area of base pad is just set to rubber type of material.
