Problems solved by technology

[0003] However, for some non-metallic workpieces, the above-mentioned electromagnetic disk cannot absorb the workpiece, resulting in that ordinary surface grinders cannot perform normal grinding on non-metallic workpieces. For example: technical requirements for grinding epoxy bakelite heat insulation boards , its parallelism and flatness both reach 0.003; since this board cannot be adsorbed by the electromagnet of a common surface grinder, and the method of positioning with a common baffle plate cannot make the parallelism and flatness of the epoxy bakelite heat insulation board reach The technical requirements of 0.003 have seriously restricted the grinding of some non-metallic workpieces, and also reduced the processing range of ordinary surface grinders.

Embodiment Construction

[0015] refer to figure 1 , Fig. 2, a kind of surface grinder that adopts vacuum suction cup, comprises grinder base 1, and described grinder base 1 is fixedly provided with a vacuum suction cup 2 with smooth surface, in order to save material, reduce the weight of vacuum suction cup 2 simultaneously, described The middle and lower parts of the left and right sides of the vacuum chuck 2 are respectively provided with a depression 22; the upper surface of the vacuum chuck 2 is provided with a bare groove 20, that is, when the workpiece 5 is not placed on the upper surface of the vacuum chuck 2, people can directly see it. The groove 20 located on the upper surface of the vacuum chuck 2, here, as a preferred embodiment of the present invention, the groove 20 is preferably designed to include two square ring grooves inside and outside, and a cross groove connecting the opposite corners of the outer square ring groove, so The above-mentioned intersecting groove passes through the a...

Abstract

The invention discloses a flat grinder using a vacuum chuck. The flat grinder using the vacuum chuck comprises a grinder base which is fixedly provided with the vacuum chuck with the smooth and flat surface. The upper surface of the vacuum chuck is provided with a bare groove, one side face of the vacuum chuck is provided with a through hole which is communicated with the groove, and the through hole is connected with a vacuum pump through a vacuum suction tube. Due to the facts that a vacuum chuck structure used for sucking workpieces is arranged on the upper surface of the flat grinder, and metal or non-metal workpieces can be sucked through the vacuum chuck, the flat grinder is suitable for machining non-metal workpieces, and meanwhile enlarges the machining range of the flat grinder.

Description

technical field [0001] The invention relates to a surface grinder, in particular to a surface grinder using a vacuum suction cup. Background technique [0002] At present, ordinary surface grinders on the market mainly use electromagnetic disks to absorb the workpiece, and then the surface grinder grinds the workpiece. [0003] However, for some non-metallic workpieces, the above-mentioned electromagnetic disk cannot absorb the workpiece, resulting in that ordinary surface grinders cannot perform normal grinding on non-metallic workpieces. For example: technical requirements for grinding epoxy bakelite heat insulation boards , its parallelism and flatness both reach 0.003; since this board cannot be adsorbed by the electromagnet of a common surface grinder, and the method of positioning with a common baffle plate cannot make the parallelism and flatness of the epoxy bakelite heat insulation board reach The technical requirement of 0.003 severely restricts the grinding proce...
