Abstract
The utility model discloses a grinding head device, which comprises a main shaft, a belt wheel and a grinding head component, wherein a rotating turntable is provided and sleeved on the main shaft; the rotating turntable is fixedly connected with the main shaft; the grinding head component comprises a plurality of uniformly distributed grinding heads which are fixed on the rotating turntable; a gear shaft is provided and fixed on the circumference of the rotating turntable; and the grinding heads are arranged on the gear shaft. The grinding head device adopts a planetary structure, and is meshed with a large gear which is sleeved and fixed outside the main shaft through a rotating gear. The rotating speed of a planetary grinding wheel is fast, the main shaft can exert pressure, the unstable phenomenon in the grinding process is solved, and the grinding speed and the surface quality are improved.
Description
Technical field
The utility model relates to metal and other materials processing device, the grinding head device of surface grindings such as particularly a kind of stainless steel and stone material processing.
Background technology
At present, the grinding head device of existing metal and stone grinding machine mainly comprises main shaft, belt pulley, bistrique, belt pulley are installed on the main shaft of top of mounting flange, and main shaft is an one with the ring flange that connects bistrique, belt pulley drives main axis rotation, main shaft drives the bistrique rotation, during the belt pulley rotation main shaft is applied with radial load, and such structure is difficult to guarantee the stability and the depth of parallelism of the axial force that main shaft applies bistrique.In addition, in the work of reality, the top that belt pulley is installed in mounting flange makes and seems very huge on the whole grinding head device structure, and main shaft is stressed also bad, influences grinding machine life-span and polishing quality.
The utility model content
The purpose of this utility model is: to overcome deficiency of the prior art, provide a kind of planetary mills grinding wheel head structure, steady vibration resistance of axial force and the grinding head device that grinding rate is fast, quality is high.
Technical solutions of the utility model are: a kind of grinding head device, comprise main shaft, belt wheel and grinding head assembly, it is characterized in that: be provided with rotary turnplate and be enclosed within on the main shaft, rotary turnplate is fixedlyed connected with main shaft, grinding head assembly is the fixing some equally distributed bistriques of rotary turnplate, and be provided with gear shaft and be fixed on the rotary turnplate circumference, bistrique is contained on the gear shaft, and each gear shaft is all adorned a swing pinion.
The utility model improves, and is provided with collar bush and is enclosed within on the main shaft, fixes a coaxial gear wheel on collar bush, and described swing pinion and the fixing gear wheel engagement of collar bush.
It is non-rotary gear wheel that collar bush below is provided with coaxial gear wheel, is connected by bearing between main shaft and the collar bush.The rotation of main shaft driven rotary rotating disk.Fixedly connected with rotary turnplate by key pin in the main shaft lower end.
The utility model beneficial effect is: owing to adopt planetary structure, and by swing pinion and the fixing gear wheel engagement of spindle jacket.The rotary speed of planet emery wheel is fast, and main shaft can exert pressure, and has solved the steady phenomenon of process of lapping, has improved grinding rate and surface quality.
