Abstract

The utility model discloses a planet type pneumatic glaze polishing grinding head, which comprises a bracket, a standard cylinder arranged on the bracket, a drive main shaft, a belt pulley drive mechanism, a planet wheel drive mechanism, a grinding disc driven by every planet rotary shaft and a grinding sheet arranged on the grinding disc, wherein, each planet rotary shaft connected with the grinding disc is provided with a cylinder capable of pushing the planet rotary shaft to move downwards. The design makes each set of grinding disc and sheet obtain independent downward pressing force and can fluctuate according to the form of processed brick surface; meanwhile, the utility model can effectively retain original accidented form of brick surface and glaze layer and is characterized by high degree of finish of grinding, overall and even polishing and extensive application scope etc.; moreover, the utility model can be used in processing of glaze surface of ceramic brick to greatly improve decorative effect of brick surface.

Description

Planetary pneumatic throwing glaze bistrique

Technical field

The utility model relates to grinding, polishing processing device, especially for the bistrique of ceramic brick surface glaze layer polishing.

Background technology

Tradition is used for the grinding head for polishing of ceramic brick surface processing, for improving the precision of grinding, the planetary grinding head for polishing that adopt with a plurality of small-sized minute bistrique, its structure more mainly by standard cylinder, transmission mechanism, planetary gear transmission mechanism, it is a plurality of that independently mill and abrasive disc etc. are formed separately.Each mill, abrasive disc are positive drive with drive mandrel and are connected.Such bistrique although processing fineness is higher, has ups and downs not plane then can't polish processing effectively for ceramic brick surface.And at present to the polishing of Ceramic Tiles, more diversified for the level effect that makes the brick face except fineness, people painstakingly will keep the concavo-convex fluctuations of glaze.Like this, higher to the processing request of grinding head for polishing, promptly want bistrique can follow the tracks of the micro-strain of brick face, the irregular glaze that makes the brick face also can be by grinding-polishing to a certain degree, but not scabbles.This is that traditional planetary grinding head for polishing can't be realized.

The utility model content

The purpose of this utility model is the weak point that overcomes prior art, proposes a kind ofly to polish the precision height, can initiatively adapt to the planetary pneumatic throwing glaze bistrique that surface to be machined distortion rises and falls again.

The utility model adopts following technical scheme: planetary pneumatic throwing glaze bistrique, include support, be loaded on the standard cylinder on the support, transmission main shaft, pulley transmission mechanism, the planetary gear transmission mechanism, the mill that drives by each planet rotating shaft and on abrasive disc, all be equipped with in each the planet rotating shaft that is connected with mill and can promote the cylinder that the planet rotating shaft moves downward.Further, for reducing pipeline, realizing unified central gas supply, provide compressed-air actuated tracheae to be drawn by ventilation mandrel branch to each cylinder, and puncture core is axially gone up the ventilation inner core in the butt transmission main shaft, the ventilation inner core then connects rotary hydraulic quick coupler and air valve.For improving the precision of grinding, equipment can be out of shape in the less fluctuating of tracked surface, being planetary mill and the abrasive disc that is distributed under the transmission main shaft has the 2-6 group.Simultaneously, the top of every group of mill is all hinged with the planet rotating shaft formation sphere of its top.

Such structure has tangible advantage:

When 1, each bistrique, abrasive disc revolved round the sun around transmission main shaft, self also drove rotation by the planetary gear transmission mechanism, so the linear velocity of its grinding is big, the grinding accuracy height;

2, every group of bistrique, abrasive disc are joined a cylinder separately, and every group of bistrique, abrasive disc are to the grinding pressure uniformity of brick face, even ups and downs surface also can keep constant compression force, so grinding comprehensively and evenly;

3, hinged bistrique, the abrasive disc of making of sphere can be done certain universal adjustment, can independently follow the form of finished surface and float to adapt to voluntarily, is particularly suitable for the polishing of the rough ceramic brick glaze layer of surface height.

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

Fig. 2 is the A-A profile of Fig. 1 transmission main shaft;

Fig. 3 is the local enlarged diagram of bistrique.

The specific embodiment

Referring to Fig. 1-Fig. 3, the pneumatic throwing glaze bistrique of present embodiment mainly by standard cylinder 10, support 17, pulley transmission mechanism, transmission main shaft 13, be loaded on the planetary gear transmission mechanism of transmission main shaft 13 belows, the five groups of mills 2 and the abrasive disc 1 that are driven by the planetary gear transmission mechanism form.Wherein milled portion is connected with transmission main shaft 13 by mounting flange 8, and corresponding every group of top that drives the planet rotating shaft 5 of mill 2 rotations all is equipped with a slim cylinder 7.

When motor drives transmission main shaft 13 rotations by belt pulley 18, drive mounting flange 8 and throw glaze bistrique

lower casing

3 and 6 rotations simultaneously of throwing axle bistrique loam cake, because five groups of planetary gears 4 and planet rotating shaft 5 are installed on by bearing and throw axle bistrique lower casing 3 and throw on the axle bistrique loam cake 6, so when transmission main shaft 13 rotates, also drive five groups of planet rotating shafts 5 together and do revolution motion around transmission main shaft 13;

Fixed gear 12 is placed in by bearing and throws on the glaze bistrique ventilation mandrel 11, and is connected with reference column 16 on the outer frame by seal cover 9 and positive stop, in order to cooperate each planetary gear 4; Because the revolution motion of planetary gear 4 and planet rotating shaft 5, and fixed gear 12 relative fixed, planetary gear 4 and planet rotating shaft 5 certainly lead to spinning motion so, respectively organize mill 2, the existing revolution of abrasive disc 1 realization thereby make, and the planetary compound motion of rotation is arranged again;

When driving mill 2, abrasive disc 1 rotate, by the transmission main shaft 13 that is connected with bistrique and on high-speed rotary hydraulic quick coupler 14 and air valve 15 can be simultaneously downwards respectively organize mill 2, abrasive disc 1 provides water and compressed air, water through in the transmission main shaft 13 with the inlet channel of ventilating between the inner core 21, directly flow to the surface of workpiece to be machined, play cooling and the effect of removing contamination, compressed air then passes through the central air induction road of the ventilation inner core 21 in the transmission main shaft 13, arrive each tracheae 19 through ventilation mandrel 11 finger assignments again, enter each slim cylinder 7 then; After slim cylinder 7 air inlets, promoting planet rotating shaft 5 moves downward, planet rotating shaft this moment 5 also rotatablely moves simultaneously, because compressed air provides with the constant voltage form, so the pressure of each slim cylinder 7 pairs of each planet rotating shafts 5 also is constant, so just realized the constant voltage grinding work of five groups of

mills

2,1 pair of workpiece of abrasive disc;

Because each unsteady mill 2 top is all hinged with planet rotating shaft 5 formation spheres, spherical hinge 20 can form the multiple degrees of freedom swing, and every planet rotating shaft 5 is with constant voltage work, even therefore there is out-of-flatness in surface of the work, when promptly having crooked cambered surface, abrasive disc 1 also can be followed the tracks of original form of surface of the work well, and the polished glaze degree of depth is consistent substantially.

Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
