Description

Grinding head for polishing

The utility model relates to a kind of grinding head for polishing.

Existing bistrique has two kinds, and a kind of is planet grinding head, and its rotating diameter can not float than big and the surfaces of revolution; Another kind is square abrading block, and its bistrique is shuttle-type, though the surfaces of revolution can float, its rotating diameter is big, and abrading block is big longer with the contact wire that changes face; Adopt above-mentioned two kinds of traditional bistriques that glazed tile is polished, can produce local phenomenon of leaking throwing or show-through base, be not suitable for the polishing of glazed tile.

It is little and bistrique is relocatable that the novel purpose of the utility model provides a kind of bistrique rotating diameter, can be used for the grinding head for polishing of glazed tile polishing.

In order to achieve the above object, the utility model is achieved in that the bistrique that it comprises main shaft, is enclosed within the outer fixed cap of main shaft, abrading block seat and is connected with the abrading block seat; Main shaft is rotatable in fixed cap; It is characterized in that: it also comprises a chassis, and the axle sleeve on the chassis is enclosed within on the main shaft, and is gapped between axle sleeve and the main shaft; Tail end at main shaft is provided with the curved middleware in surface, and middleware is provided with elastic device; Be provided with associated gland on middleware, gland, middleware are connected by securing member with the chassis; Also be with gear wheel on main shaft, gear wheel is fixedlyed connected with fixed cap; Be provided with rotating shaft on the chassis, an end of rotating shaft is provided with pinion, pinion and gear wheel engagement, and the other end of rotating shaft is connected with terminal pad, and the axle sleeve of rotating shaft and axle sleeve lid are fixedlyed connected with the chassis; Terminal pad is connected with the abrading block seat.Above-mentioned middleware comprises shaft joint and Ball faced nut, and elastic device is located on the shaft joint, and this elastic device be positioned at securing member around.Securing member is a bolt.Fixed cap is pegged graft mutually with the chassis and is cooperated, and relative fixed lid in chassis is rotatable.Terminal pad is pegged graft mutually with the axle sleeve lid and is cooperated, and rotatable relatively.

The utility model compared with prior art has following advantage:

1, the size of abrading block is little;

2, the rotating diameter of bistrique is little;

3, the relative brick face of the surfaces of revolution of bistrique can float, and abrading block is fully contacted with the brick face;

4, in light weight, volume is little.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a upward view of the present utility model.

Below in conjunction with drawings and Examples the utility model is done further detailed description:

As shown in Figure 1, 2, comprise that main shaft 1, the fixed cap 2, the abrading block seat 6 that are enclosed within outside the main shaft 1 reach the bistrique 7 that is connected with abrading block seat 6; Below abrading block seat 6, be positioned on the contact-making surface of bistrique 7 and be provided with elastic device 18; Main shaft 1 is rotatable in fixed cap 2, and fixed cap 2 fixed-site are motionless.It also comprises a chassis 3, and the axle sleeve 13 on the chassis 3 is enclosed within on the main shaft 1, and is gapped between axle sleeve 13 and the main shaft 1; Tail end at main shaft 1 is provided with shaft coupling 11, is provided with Ball faced nut 8 on shaft coupling 11, and shaft coupling 11 is gapped with the contact-making surface on chassis 3, and elastic device 10 is located on the shaft joint 11; Be provided with the gland 9 that matches with it on Ball faced nut 8, gland 9, shaft coupling 11 are connected by bolt 14 with chassis 3, elastic device 10 be positioned at bolt 14 around.Also be with gear wheel 12 on main shaft 1, gear wheel 12 is fixedlyed connected with fixed cap 2.On chassis 3 symmetry be provided with three rotating shafts 4, an end of every rotating shaft 4 is equipped with pinion 17, pinion 17 and gear wheel 12 engagements, the other end of rotating shaft 4 is connected with terminal pad 5, the axle sleeve 15 of rotating shaft 4 and axle sleeve cover 16 fixedlys connected with chassis 3; Terminal pad 5 is connected with abrading block seat 6.Fixed cap 2 is pegged graft mutually with chassis 3 and is cooperated, and chassis 3 relative fixed lid 2 is rotatable.Terminal pad 5 is pegged graft mutually with axle sleeve lid 16 and is cooperated, and rotatable relatively.During work, by main shaft 1, shaft coupling 11, elastic device 10 and bolt 14 rotation is delivered on the chassis 3, three pinion shafts 4 on the chassis 3, terminal pad 5, abrading block seat 6, abrading block 7 rotate with chassis 3; In addition because pinion 17 and gear wheel 12 engagements produce rotation thereby drive terminal pad 5, abrading block seat 6 and abrading block 7; Again because the glazed tile surface irregularity, when abrading block 7 rotations are polished it, three round abrading blocks 7 are because of unbalance stress, this out-of-balance force is delivered on the chassis 3 by abrading block seat 6, terminal pad 5, pinion shaft 4, gapped between chassis 3 and the main shaft 1, the sphere bindiny mechanism of chassis 3 between gland 9 and Ball faced nut 8 realizes abrading block 7 surfacess of revolution floating around the centre of sphere of Ball faced nut 8.
