Abstract
The utility model discloses a device for polishing grinding heads of planetary gears with line-contact grinding method, which consists of a main shaft, fixed sun gears sleeved on the main shaft, a grinding head upper cover and a grinding head lower cover which are arranged on the main shaft and rotate synchronously under the driving of the main shaft, a plurality of planetary gear shafts arranged in the grinding head lower cover and meshed with the fixed sun gears sleeved on the main shaft, and grinding tools arranged below the planetary gear shafts; the fixed sun gears sleeved on the main shaft are bevel gears, and the planetary gear shafts meshed with the fixed sun gears are also the bevel gears; the axial included angle between each sun gear and each planetary gear shaft ranges from 0.5 DEG to 5 DEG. Therefore, the traditional surface-contact grinding method is replaced by the line-contact grinding method, the consumption of grinding power is reduced, and the surface polishing quality of workpieces is improved; in addition, the pretightening forces of inner elastic components and compensating components can be adjusted freely to meet the requirements of different surface conditions under the circumstance that a grinding head assembly is not disassembled.
Description
Technical field
The utility model relates to pottery or glassware deep processing equipment, particularly by the grinding head for polishing device of planetary gear transmission.
Background technology
At existing ceramic, especially in the grinding-polishing technology of Ceramic Tiles, use the main shaft revolution drive in it several planetary gears from then be the process equipment of using always to the grinding head device that workpiece carries out grinding-polishing.But the design that its structure adopts planet wheel spindle and main shaft to be parallel to each other, what make that the grinding tool of planet wheel spindle end face forms with surface of the work when grinding work piece is that face contacts, so not only increased the power consumption of grinding, the inner abrasive dust that produces of grinding tool also is difficult to efflux simultaneously, thereby very easily caused the secondary of surface of the work to scratch, influenced the quality of finish of product.In addition, existing other planet grinding head for polishing device adopts the double-layer gear drive mechanism, and not only heaviness, and the preload pressure of its inner elastic compensating element can only could realize regulating under the situation of dismounting bistrique assembly, therefore uses very inconvenient.
The utility model content
The purpose of this utility model is the weak point that overcomes above-mentioned conventional art, a kind of planetary gear grinding head for polishing device of line contact grinding is proposed, can change face contact grinding is line contact grinding, not only reduce the consumption of grinding power, and can improve the surface quality of workpiece greatly, can also adapt to the processing of the concavo-convex situation workpiece of different surfaces simultaneously.
The purpose of this utility model is achieved by the following technical solution: a kind of planetary gear grinding head for polishing device of line contact grinding, include main shaft, be set on the main shaft and fixed sun gear, be loaded on the main shaft and drive the bistrique loam cake of revolution synchronously by main shaft, the bistrique lower cover, be loaded on a plurality of planet pins that mesh with the main shaft sun gear in the bistrique lower cover, and the grinding tool that is loaded on each planet pin lower end, the sun gear that is loaded on the main shaft is a bevel gear, each planet pin that meshes with sun gear also is a conical tooth shaft, and both axis angle scopes are 0.5 °-5 °.Further, contact with workpiece alignment for forming, the inclination mode of grinding tool and bevel planet gear axle can be: the fixed star bevel gear is positive bevel gear, and the axis of each the planet conical tooth shaft that is engaged with all upwards meets at a bit, forms positive taper.Also can be: the fixed star bevel gear be the back taper gear, and the axis of each the planet conical tooth shaft that is engaged with all meets at downwards a bit, forms back taper.For conveniently under the situation of not dismantling the bistrique assembly, can obtain the local deformation of different polishing effects and adaptation surface of the work, on each planet conical tooth shaft flexible member is housed all, covers corresponding flexible member place on the bistrique and have the hole and expose and be provided with the adjusting bolt that can change the flexible member pretightning force.
Such design, by the certain angle of the relative main shaft inclination of planet pin with rotation, make the grinding tool of its end face when grinding, produce a less inclination angle, thereby form processing work with the line contact, avoided that to contact the grinding force that brings excessive owing to the grinding tool and the face on workpiece to be machined surface, the defective that abrasive dust is difficult to discharge.Not only improve production efficiency, and improved the crudy of surface of the work.On each planet conical tooth shaft, all add simultaneously freely regulated pressure compensation flexible member, can be under the prerequisite of not dismantling the bistrique assembly, directly,, regulate simple and convenient to obtain the local deformation of different polishing effects and adaptation surface of the work at its preload pressure of equipment adjusted.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of back taper state;
Fig. 3 is the schematic diagram of positive cone-shaped attitude.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the grinding head for polishing device of present embodiment mainly is made of main shaft 1, bistrique loam cake 2, bistrique lower cover 3, fixed star bevel gear 4, four planet conical tooth shafts 5, four bistriques 6, wherein, main shaft 1 revolves round the sun synchronously by fixedly connected drive bistrique lower cover 3 and bistrique loam cake 2, because rotatablely moving of bistrique lower cover 3 drives planet conical tooth shaft 5 and also does revolution in the lump.And fixed star bevel gear 4 is relatively-stationary with device body, fixed star bevel gear 4 is sleeved on the main shaft 1, main shaft 1 links to each other with bistrique lower cover 3, planet conical tooth shaft 5 is installed on the bistrique lower cover 3, the angle theta of planet conical tooth shaft 5 axis and fixed star bevel gear 4 axis is 1 °, and all gear pairs all adopt the external toothing form.So, planet conical tooth shaft 5 is when doing revolution motion around fixed star bevel gear 4, and self has also produced spinning motion.Each bistrique 6 carries out the grinding-polishing of line contact to surface of the work by the compound motion of this revolution and rotation and inclination certain angle.
Simultaneously,, improve the ground effect of described grinding head device, on each planet conical tooth shaft 5, all add flexible member 7 and expose accordingly and regulate bolt 8 for adapting to the deformation of unevenness of surface of the work.Make each planet conical tooth shaft 5 can both produce compression displacement independently, thereby bistrique 6 can freely be fluctuated, with the phenomenon of avoiding leaking mill, leaking throwing.The effect of regulating bolt 8 is to make flexible member 7 before work, has certain preload pressure, and the operator can cover on bistrique freely and regulate according to the characteristic of institute's grinding work piece and the characteristic of flexible member.
In addition, the planet conical tooth shaft is installed and is processed with the slanted angle mode that the fixed star bevel gear also can be adopted into positive taper, as shown in Figure 3, can reach good grinding-polishing effect equally.Certainly, only enumerated two kinds 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.
