Description

Grinding equipment capable of continuously grinding multiple workpieces

The present invention relates to the field of a workpiece surface grinder, and more particularly to an apparatus for continuous multi-face grinding and for curved surface grinding.

Most of the products are made up of a plurality of block, plate or strip workpieces. Traditionally, the surfaces of these workpieces have been textured and polished. However, due to the ever-changing design concept, today's products will have different curvature shapes. Breakthroughs and changes in this design concept will undoubtedly give consumers more choices, but the surface processing also impacts manufacturing and processing industries. Taking grinding and polishing as an example, the conventional sanding machine mainly has a belt pulley on the machine base and an abrasive cloth belt on the outer side, and a belt pulley is arranged corresponding to the belt wheel, and an appropriate spacing is reserved between the driving wheel and the belt. According to the workpiece, the workpiece is placed between the driving wheel and the abrasive belt, and the frictional force generated by the surface of the workpiece is driven by the rotating wheel to form a relative movement between the workpiece and the abrasive belt to achieve the surface polishing and grinding process.

However, for a workpiece with curvature, the workpiece will move during the machining process, and thus the belt cannot be reliably contacted with the workpiece, so the machining effect is not good; although the operator can adjust and improve the workpiece and sand by manpower. Contact with a grinding wheel, but this is obviously inconvenient and wastes manpower.

In addition, for the longitudinal curved surface, the abrasive belt needs to fluctuate with the curvature of the curved surface and conform to the surface of the workpiece. However, the abrasive belt cannot exert excessive force on the surface of the workpiece to avoid the surface of the workpiece. Increased wear, resulting in poor grinding quality.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a polishing apparatus capable of continuously multi-face grinding a workpiece, which has the effect of being capable of performing continuous grinding processing in the transverse direction and the longitudinal direction.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a grinding apparatus that can continuously grind a workpiece in a multi-faceted manner, which has the ability to provide a stable abrasive force to the curved surface of the workpiece, and which can react rapidly as the workpiece curvature changes so that the abrasive assembly does contact the workpiece surface.

In order to achieve the above object, the present invention discloses a grinding apparatus comprising a first transverse grinding machine adjacent to a first longitudinal grinding machine, wherein the first transverse grinding machine has two first lateral grinding mechanisms, and two a lateral grinding mechanism is opposite and relatively displaceable, whereby the side of the workpiece can be ground; the first longitudinal grinding machine has a movable first longitudinal grinding mechanism, and the first longitudinal grinding mechanism can be used The surface curvature of the workpiece fluctuates to achieve the effect of longitudinal grinding.
