Equipment for processing medium-radius arc surface on wall bar in furniture piano

Abstract

The invention relates to the technical field of furniture, and discloses equipment for processing a medium-radius arc surface on a wall bar in a furniture piano. The equipment comprises a box body, wherein a crank is rotatably connected to the inner wall of the box body; a pinion is welded to the surface of the crank; a rack wheel is meshed with the surface of the pinion; a rotating plate is welded to the axis of the rack wheel through a connecting rod; a workbench is welded to the inner wall of the box body through a connecting rod; a frame is rotatably connected to the inner wall of the workbench; a cleaning mechanism is arranged on the inner wall of the frame; a sliding groove is formed in the inner wall of the box body; and a reset mechanism is arranged on the inner wall of the workbench. A worker manually rotates the crank to drive a grinding roller to move, and the grinding roller slowly descends to grind the surface of the wall bar and grind out the arc surface, so that the wall bar can be prevented from being torn in the wood grain direction, fine processing can be achieved, the rejection rate can be reduced, and cost input can be reduced.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a processing device for a medium-radius arc surface on ribs in a furniture piano. Background technique [0002] Furniture refers to the essential equipment and facilities for human beings to maintain normal life, engage in production practice and carry out social activities. Furniture also follows the pace of the times and continues to develop and innovate. Up to now, there are many categories, different materials, complete varieties, and different uses. , is an important foundation for establishing a working and living space. [0003] At present, the medium-radius circular arc surface on the middle rib of the piano needs to be manually planed or chiseled to process the circular arc surface. The tool may extend along the wood grain. When the wood grain is downward (or called reverse grain), If the cutting amount is large, tearing will occur along the wood grain direction, and ...

Problems solved by technology

[0003] At present, the medium-radius circular arc surface on the middle rib of the piano needs to be manually planed or chiseled to process the circular arc surface. The tool may extend along the wood grain. When the wood grain is downward (or called reverse grain), If the cutting amount is large, tearing will occur along the wood grain direction, and the tearing surface will even exceed the surface of the processed contour. At this time, there will be defective products or even waste products. Radius arc surface processing equipment to solve the problems raised above
