Refrigerator liner positioning device based on vacuum technology and operation method thereof

Abstract

The invention discloses a refrigerator liner positioning device based on a vacuum technology and an operation method thereof, and relates to the technical field of refrigerator machining equipment. An upper positioning panel comprises a lower positioning base plate fixed to the upper side of a fixed connecting plate, a positioning frame and inner positioning plates are fixedly arranged on the upper side surface of the lower positioning base plate, the inner positioning plates are located in the positioning frame, and the multiple inner positioning plates are arranged in the positioning frame; the surfaces of the inner positioning plates and the surface of the lower positioning base plate are all provided with air pumping holes, the air pumping holes in the lower positioning base plate communicate with the interiors of the air pumping holes in the inner positioning plates, the positioning frame is of an integrated frame structure, air in a cavity between the positioning frame and a refrigerator liner is pumped away through a vacuum generation device, and then the formed pressure difference is used for positioning, so that the problems that traditional positioning for a refrigerator liner piece is unstable in the machining process, the precision is poor, and subsequent machining of the liner piece is affected are solved.

Description

technical field [0001] The invention relates to the technical field of refrigerator processing equipment, in particular to a refrigerator liner positioning device based on vacuum technology and an operation method thereof. Background technique [0002] A refrigeration device that maintains a constant low temperature is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. The volume of household refrigerators is usually 20-500 liters. [0003] The traditional refrigerator liner parts need to be positioned during the production process, and then the subsequent processing and production operations are carried out. However, the traditional positioning of the refrigerator liner parts is unstable during the processing process, and the accuracy is poor, which affects the quality of the inner liner. Subsequent proce...
