Benefits of technology
The present invention provides a sander with an oscillation buffer element between the body and the sanding disk. This element has an elastic buffer section that deforms during operation, allowing the sanding disk to oscillate horizontally on the same plane. The elastic buffer section has a longer deformation zone, reducing stress concentration on various local structures and extending the lifespan of the sander.
Problems solved by technology
Hence operators have to apply extra effort to stabilize operation of the sander.

Embodiment Construction
[0030]Please refer to FIGS. 2 and 3 for an embodiment of the durable sander and oscillation buffer element thereof according to the invention. The durable sander mainly comprises a body 20 and a sanding disk 30. The body 20 has a housing 21 and a drive motor 22 installed in the housing 21. The drive motor 22 is connected to the sanding disk 30 through a shaft 221. The sanding disk 30 can be driven by the drive motor 22 to perform sanding movement against the body 20. The drive motor 2 can be an electric motor driven by drive power converted from external power via a power modulation circuit, or a pneumatic motor driven by high pressure gas. The sanding disk 30 has a support frame 31 and a sanding portion 32 fastened to the support frame 31. The sanding portion 32 is bonded to a sandpaper. The sander further includes at least one oscillation buffer element 40 which has an upper connection bar 41 fastened to the body 20, a lower connection bar 42 fastened to the sanding disk 30 and a ...

A durable sander comprises a body with a drive motor, a sanding disk driven by the drive motor to perform sanding movement against the body and at least one oscillation buffer element. The oscillation buffer element includes an upper connection bar fastened to the body, a lower connection bar fastened to the sanding disk and a plurality of buffer portions bridging the upper connection bar and lower connection bar in an integrated manner. Each buffer portion has a first connection end connected to the upper connection bar, a second connection end connected to the lower connection bar and an elastic buffer section interposed between the first connection end and second connection end. The length of the elastic buffer section is greater than the distance between the first connection end and the second connection end.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a sander and particularly to an oscillation buffer element used in a sander.BACKGROUND OF THE INVENTION[0002]Sanders are machine tools driven by high pressure gas or electric power to grind the surface of objects. A conventional sander comprises a drive motor to receive the high pressure gas or electric power as the driving source and a sanding disk driven by the drive motor. During sanding operation the sanding disk is bonded to a replaceable sandpaper and driven by the drive motor to make high speed oscillation about a moving track. The grinding granules of the sandpaper are is contacted with an object to flatten and smooth the contact surface or remove other object attached to the surface.[0003]During the sanding disk performing the high speed oscillation, an oscillation force is generated and transmitted to the sander body through a driving shaft of the drive motor. Hence operators have to apply extra effort to stabili...
