Aluminium profile door and window frame grinding device

Abstract

The invention relates to the technical field of door and window production, and particularly discloses an aluminium profile door and window frame grinding device. The aluminium profile door and windowframe grinding device comprises a worktable and at least one group of grinding mechanisms located on the worktable, the grinding mechanisms comprise mounting plates, grinding motors, driving wheels and abrasive belts, wherein the grinding motors are located on one sides of the mounting plates and are connected with the driving wheels through flange discs; compacting wheels for pressing the abrasive belts downwards and further grinding frames are arranged under the driving wheels; lifting assemblies for driving the compacting wheels to move up and down to adjust distances between the abrasivebelts and the frames are arranged on the compacting wheels; first transmission wheels and second transmission wheels are arranged on the two sides above the compacting wheels; the first transmission wheels are provided with tensioning assemblies for adjusting the tensity of the abrasive belts; and position adjusting assemblies for adjusting positions of the abrasive belts relative to the second transmission wheels are arranged on one sides of the second transmission wheels. By arranging the lifting assemblies on the compacting wheels and arranging the tensioning assemblies and the position adjusting assemblies on the first transmission wheels and the second transmission wheels, the rapid grinding of the aluminium profile frames is realized and the abrasive belts are prevented from fallingoff.

Description

technical field [0001] The invention relates to the technical field of door and window production, in particular to an aluminum profile door and window frame grinding device. Background technique [0002] After the aluminum profile door and window frame is welded, there will be uneven planes formed by welding shavings on the interface. At this time, it is necessary to use grinding equipment to grind the welding shavings on the interface. [0003] See the Chinese Invention Publication Patent, the publication number is CN109129129A, and the publication date is January 04, 2019. It specifically discloses an aluminum alloy weld seam grinding mechanism, including a frame, a workpiece positioning device and a grinding device. A working platform is provided, the working platform is provided with a grinding groove, the workpiece positioning device is arranged above the grinding groove and installed on the working platform, and the grinding device is fixedly arranged under the grindi...

AI Technical Summary

Problems solved by technology

[0004] Its disclosed aluminum alloy weld seam grinding mechanism, when using the abrasive belt for grinding, the abrasive belt runs at high speed under the drive of the motor. When the abrasive belt deviates, the position of the abrasive belt on the transmission wheel cannot be adjusted and set accordingly in time The corresponding tensioning mechanism causes the abrasive belt to fall off the drive wheel easily, which brings trouble to the grinding work
