Description

Multifunctional earthenware piece button disk

Technical field

The utility model relates to the fields of polishing, and in particular to Multifunctional earthenware piece button disk.

Background technique

Sander is mainly used for sanding and polishing, it is ensured that the body surface after polishing is more smooth.

Conventional bruting machine is provided with circular hole with the center position of sand piece, and coaxially connected on the motor output shaft of sander It is connect after thering is fixed disk, screw rod to pass through circular hole with fixed disk, sand piece high speed rotation is driven after electric motor starting, to be revolved using high speed The sand piece turned carries out sanding and polishing to body surface.

But since nut has exceeded the buffed surface of sand piece, so in the grinding process, it cannot be by whole sand piece and object Body surface face contact is polished, and it is not very convenient to polish, and grinding efficiency is lower.

It in order to solve this problem, is typically now that sand piece is adhered in supporting block, but in practical sanding and polishing In the process, since the revolving speed of sand piece is higher, sand piece is easy to fly away from supporting block, so as to cause staff's injury, to work The safety of personnel threatens.

Utility model content

Sand piece is snapped onto fixed disk the purpose of this utility model is to provide a kind of, to improve sand piece fastness and increasing Add sand piece and body surface contact area.

In order to achieve the above objectives, the technical solution of the utility model provides Multifunctional earthenware piece button disk, including sand piece and fastening Part, the fastener include several strips, and one end of strip is fixedly connected with sand piece, the other end and fixed disk snapping of strip.

This programme has the technical effect that by the way that sand piece to be fixedly connected on strip, while strip is snapped onto fixed disk On, the firmness of the connection of sand piece and fixed disk can be improved, sand piece will not fly away during high speed rotation from fixed disk, Ensure the safety of staff；It is suitable for centre bit being equipped with hole simultaneously or non-porous sand piece is fixed in fixed disk, thus The contact area of sand piece and body surface is increased, is conducive to whole sand piece and is contacted with body surface, convenient for beating for body surface Grinding and polishing light improves the efficiency of sanding and polishing.

Further, the fastener further includes pedestal, and the sand piece is fixedly connected with strip by pedestal.This programme It has the technical effect that and is connect convenient for relatively thin sand piece with strip.

Further, fixed disk is equipped with the card hole through fixed disk, and the strip passes through card hole and fixed disk snapping.This Scheme have the technical effect that strip passes through card hole and fixed disk snapping after, can ensure that in bruting process that fixed disk will not be relative to The rotation of sand piece, improves grinding effect.

Further, the card hole is located at the middle part of fixed disk, and fixed disk is equipped with groove, and the card hole and groove connect Logical, the pedestal is located in groove.Having the technical effect that for this programme ensures that sand piece is bonded with fixed disk, improves grinding effect.

Further, foam-rubber cushion is equipped between the sand piece and fixed disk.This programme has the technical effect that foam-rubber cushion has Certain buffer capacity, sanding and polishing can squeeze foam-rubber cushion according to sanding and polishing degree in the process, to change sand piece and object The contact dynamics on surface.

Further, the groove is in trapezoidal shape, the pedestal and groove joggle.This programme has the technical effect that a side Face ensures that fixed disk will not be rotated relative to sand piece in bruting process, on the other hand can improve the fastening journey of pedestal and fixed disk Degree.

Further, the card hole is located at the edge of fixed disk.This programme has the technical effect that card hole is opened in process If more convenient.

Further, the edge snapping of the strip and fixed disk, fixed disk are equipped with tongue-and-groove, are fixed on the pedestal With the tenon of tongue-and-groove joggle.Having the technical effect that for this programme ensures that fixed disk will not be rotated relative to sand piece in bruting process, i.e., Ensure that fixed disk will not skid in bruting process.

Further, the diameter of the sand piece is greater than the diameter of fixed disk.On the one hand having the technical effect that for this programme avoids Fixed disk is contacted with object to be polished, and on the other hand can ensure that the edge of sand piece can be with deformation occurs.

Further, screw rod is connected in fixed disk.This programme has the technical effect that screw rod convenience and various polishing machines Connection uses.

Specific embodiment

It is further described below by specific embodiment:

Appended drawing reference in Figure of description include: sand piece 1, fixed disk 2, pedestal 3, strip 4, foam-rubber cushion 5, threaded hole 6, Card hole 7, tenon 8, screw rod 9.

Embodiment is basic as shown in attached drawing 1-5: Multifunctional earthenware piece as shown in Figure 1 buckles disk, including sand piece 1,2 and of fixed disk Fastener, sand piece 1 are made of vulcan fibre, and fixed disk 2 is made of plastic cement, and the diameter of sand piece 1 is greater than the diameter of fixed disk 2.Fastener Including pedestal 3 and six roots of sensation strip 4, pedestal 3 and strip 4 are also made of plastic cement, wherein strip 4 by with certain deformation but have The material of certain degree of hardness is made also possible；The upper end of pedestal 3 and 1 glue of sand piece are welded in one (certain pedestal 3 and sand piece 1 One can also be adhered to by viscose glue), the lower end of pedestal 3 and the upper end of strip 4 are welded in one also by glue.

As shown in Figure 1, being provided with groove in fixed disk 2, pedestal 3 is located in groove, and certainly, groove and pedestal 3 can be set At trapezoidal shape as shown in Figure 3, pedestal 3 and groove joggle at this time.And as shown in Figure 1,3, it is set between sand piece 1 and fixed disk 2 It is equipped with foam-rubber cushion 5, the upper end of foam-rubber cushion 5 and sand piece 1 are by viscose glue adhesion, and the lower end of foam-rubber cushion 5 is also by viscose glue and fixed disk 2 Adhesion.

As shown in Fig. 2, threaded hole 6 and six card holes 7 through fixed disk 2 are provided in fixed disk 2, as shown in Figure 1, card Hole 7 is connected to the bottom of groove, and the size of card hole 7 is slightly larger than the size of 4 lower end the widest part of strip, and such strip 4 utilizes itself Deformation is buckled in one with fixed disk 2 after card hole 7；Certainly, card hole 7 can also be provided with the side of fixed disk 2 as shown in Figure 4 Edge, such strip 4 are equally buckled in one with fixed disk 2 after passing through card hole 7；Alternatively, as shown in figure 5, strip 4 can also be direct With the edge snapping of fixed disk 2, need to open up tongue-and-groove at this time in fixed disk 2, and need on the base 3 glue weld one by Tenon 8 made of plastic cement, tenon 8 are pressed into tongue-and-groove.
