Description

Technical Field

[0002] In the production process of panel furniture, most of the panels need to be punched, and the holes are of various types. If the processing can only be carried out by constantly changing the drill bit during the processing, this will lead to low processing efficiency. Therefore, CNC drilling equipment was invented. CNC drilling equipment is a special equipment for high-precision CNC drilling centers, with high-precision product performance at the Seiko level; the CNC drilling of existing CNC drilling equipment consists of a lower vertical row assembly, an upper vertical row assembly, and a side row assembly. When assembling the upper vertical row assembly, since it is in the opposite direction to the lower vertical row assembly, the upper vertical row assembly needs to be flipped 180° after being assembled on the assembly jig, and then the entire upper vertical row assembly after flipping is hoisted and installed.

[0003] The existing flipping method of the upper vertical row assembly is mainly carried out by manpower and a bridge crane. When flipping, the lifting device is connected to the upper end of the upper vertical row assembly, and the upper vertical row assembly is vertically lifted from the assembly frame by the bridge crane. Then, with the assistance of multiple people, the upper vertical row assembly is slowly placed on a horizontal ground covered with a protective pad, the lifting device is removed, and the lifting device is connected to the other end of the upper vertical row assembly. With the assistance of multiple people again, the upper vertical row assembly is vertically lifted again by the bridge crane to complete the flipping. Such a flipping method requires the assistance of multiple people, which will cause waste of human resources, low production efficiency, high labor intensity of operators, etc., and automatic flipping control cannot be achieved. In addition, during the flipping process, rigid objects are prone to damage and scratches on the components.

[0060] A method for flipping a vertical row assembly flipping tool on a numerically controlled drilling machine, based on the vertical row assembly flipping tool on the numerically controlled drilling machine, comprises the following steps:
