Benefits of technology

[0007]The main objective of the invention is to provide a sander that can finely sand a working surface of an object by adding another sanding direction.

Problems solved by technology

However, sanding effect of the conventional sander is limited since the abrasive assemblies can only rotate and reciprocate in a direction parallel to the X-axis.

Embodiment Construction

[0021]With reference to FIGS. 1 and 2, a sander in accordance with the present invention comprises a base (10), a rotating assembly (20), multiple abrasive assemblies (30), multiple driving assemblies (40), multiple reciprocating assemblies (50), and multiple panels (60).

[0022]With further reference to FIG. 3, the base (10) has a body (11), a conveyer belt (13), a belt driver (15), a power distribution device (17), an elevating device (19) and an elevating frame (1B).

[0023]The body (11) is a rectangular parallelepiped and has a top, a bottom, two longitudinal sides, four corners, four stanchions (111) and a supporting frame (112). A Z-axis is defined as a direction from the bottom to the top of the body (11). A Y-axis is defined as a direction from one longitudinal side to the other and is perpendicular to the Z-axis. An X-axis is defined as a direction that is perpendicular to the Z-axis and the Y-axis. An X-Y plane is defined as a plane that contains the X-axis and the Y-axis. The...

Abstract

A sander has a base, a rotating assembly, multiple abrasive assemblies, multiple driving assemblies and multiple reciprocating assemblies. The rotating assembly is rotatably mounted on the base on an axis that is parallel to a Z-axis and has a bottom end. The abrasive assemblies move linearly and reciprocatorily in a plane parallel to an X-Y plane and are rotatably mounted on the bottom end of the rotating assembly. The driving assemblies are respectively connected to and drive the abrasive assemblies to rotate. The reciprocating assemblies are mounted securely on the rotating assembly to linearly and reciprocatorily drive the abrasive assemblies in a plane parallel to the X-Y plane. A linear reciprocating direction of each abrasive assembly is opposite to that of an adjacent abrasive assembly.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a sander, and more particularly to a sander that can finely sand a working surface of an object.[0003]2. Description of Related Art[0004]A conventional sander comprises a base, multiple abrasive assemblies, multiple driving assemblies and multiple reciprocating assemblies. The base has a body and a conveyer belt. The conveyer belt is mounted movably through the body in a direction parallel to a Y-axis to convey an object which is about to be sanded or polished. The abrasive assemblies move reciprocatorily in a direction parallel to an X-axis and are mounted rotatably on the body and are disposed above the conveyer belt to sand the object. The driving assemblies are respectively connected to and drive the abrasive assemblies to rotate. The reciprocating assemblies are respectively mounted on the abrasive assemblies to drive the abrasive assemblies reciprocatorily in a direction parallel t...
