Sander bottom a kind of storage sphere
The present invention relates to sander bottom surface finish handling machine apparatus field, particularly a kind of storage sphere.
CNG gas cylinder spherical bottom can produce a lot of ripple glaze after spinning, in order to attractive in appearance, just needs these ripple glazes to polish off.Prior art is all with hand-held grinder buffing, and dust and noise are very large, and labor intensive is also large, and efficiency is also very low.
In sum, for the deficiencies in the prior art and defect, need a kind of rotation easy to use flexibly especially and the sander of increasing work efficiency, to solve above-mentioned technical problem.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, easy to use, rotate flexibly and sander bottom the storage sphere of increasing work efficiency.
Technical problem solved by the invention can realize by the following technical solutions:
Sander bottom a kind of storage sphere, comprising:
One universal rotation mechanism;
Be fixed on the motor base on described universal rotation mechanism;
Be arranged on the motor on described motor base;
Be arranged on the polishing nose on described motor base, driven by belt gear between described polishing nose with described motor and be connected.
In a preferred embodiment of the invention, described universal rotation mechanism comprises:
One bearing holder (housing, cover) serving as handle;
By the rotating shaft of bearings in described bearing holder (housing, cover);
Be fixed on the crotch on described rotating shaft,
The bottom of described motor base is provided with a longitudinal axis, the described longitudinal axis is provided with a radial axle, and described radial axle is supported on described crotch by oscillating bearing.
In a preferred embodiment of the invention, described polishing nose comprises:
Be fixed on the head support on described motor base;
Be fixed on the head bearing block on described head support;
Be located at the head rotating shaft in described head bearing block by bearing shaft, described head rotating shaft is stretched out by described head bearing block two ends, and driven by belt gear between its one end with described motor output shaft and be connected, the other end is fixed with grinding wheel;
To be arranged on above described grinding wheel and the protective cover be fixed on head bearing block.
Owing to have employed technical scheme as above, when the present invention polishes, grinding wheel can swing according to CNG gas cylinder spherical bottom shape, and therefore grinding wheel can be good at fitting with CNG gas cylinder spherical bottom surface.Thus improve grinding efficiency, also reduce labour intensity simultaneously.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment and diagram, setting forth the present invention further.
See Fig. 1 and Fig. 2, sander bottom the storage sphere provided in figure, comprises three phase electric machine 20, and three phase electric machine 20 is arranged on a motor base 21, be provided with one in the bottom of motor base 21 to the longitudinal axis 22 of downward-extension, the longitudinal axis 22 is provided with a radial axle 23.
Feature of the present invention is, also comprise a universal rotation mechanism 30, this universal rotation mechanism 30 comprises the bearing holder (housing, cover) 31 that serves as handle, the rotating shaft 33 in bearing holder (housing, cover) 31 is supported on by bearing 32, be fixed with a crotch 34 on the top of rotating shaft 33, radial axle 23 is arranged on crotch 34 by oscillating bearing 35.Such motor base 21 just can rotate around the longitudinal axis 22, can swing by radial axle 23 again simultaneously.
Polishing nose 10 of the present invention comprises the head support 11 be fixed on motor base 21, head support 11 is fixed with a head bearing block 12, head rotating shaft 13 is located in head bearing block 12 by bearing 14 axle, head rotating shaft 13 is stretched out by head bearing block 12 two ends, its one end key is provided with a driven pulley 41, and the other end is fixed with grinding wheel 14.On the output shaft of three phase electric machine 20, key is provided with a drive pulley 42, is surrounded with belt 43 between drive pulley 42 and driven pulley 41.
Drive pulley 42 and driven pulley 41 are V type belt pulley, and belt 43 is V type belt; Above grinding wheel 14, be provided with semilune protective cover 15, semilune protective cover 15 is fixed on head bearing block 12, and when preventing polishing nose from working, dust flashes, and also prevents staff from being accidentally injured in the course of the work simultaneously.
The operation principle of this sander is as follows:
When need the CNG gas cylinder spherical bottom being polished polishing put in place after, open three phase electric machine 20, three phase electric machine 20 drives grinding wheel 14 to rotate by belt gear, head rotating shaft 13, sanding and polishing is carried out to the ripple glaze at the CNG gas cylinder spherical end, make the CNG gas cylinder spherical end become smooth, increase attractive in appearance.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
