Machining device and machining method for aluminum signboard special-shaped round hole

Abstract

The invention discloses a machining device for an aluminum signboard special-shaped round hole which comprises a base, a cover plate and a punch. A clamping groove used for containing a signboard to be machined is formed in the base, the depth of the clamping groove is the same as the thickness of the signboard to be machined, and a discharging hole is formed in the clamping groove. A punch guide hole is formed in the cover plate; the hole position of the punch guide hole corresponds to the hole position of a blanking hole; the shape of the blanking hole is consistent with that of the special-shaped round hole of the signboard; and the peripheral shape of the lower end of the punch is consistent with the shape of the special-shaped round hole of the signboard. When the machining device is used for machining the special-shaped round hole of the aluminum signboard, the signboard to be machined only needs to be placed on the clamping groove of the base and then covered with the cover plate, the punch is used for conducting punching operation, machining of the special-shaped round hole can be completed, the structure is simple, and operation is fast and convenient.

Description

technical field [0001] The invention relates to the technical field of identification plate processing of aero-engine casing parts, in particular to a processing device and a processing method for special-shaped round holes of aluminum identification plates. Background technique [0002] Aluminum identification plates (such as figure 1 Shown) are very common in aero-engine casing parts, they are often used for product identification of accessory casing parts, and such products are often assembled randomly, with a large number and variety. Usually the length of the aluminum identification plate is 90mm, width 50mm, thickness 3mm. [0003] When the identification plate is assembled on the accessory casing, it is necessary to process special-shaped round holes at the four corners of the identification plate. Because the material of the identification plate is thin, the traditional processing is to use three-axis CNC machining, which is processed by drilling and milling. , whi...

Problems solved by technology

[0003] When the identification plate is assembled on the accessory casing, special-shaped round holes need to be machined at the four corners of the identification plate. Because the material of the identification plate is thin, the traditional processing is to use three-axis CNC machining, which is processed by drilling and milling. , which is neither economical nor efficient; in addition, alignment is required during processing, and a flat vise is required for alignment and clamping, which takes a long time for clamping, resulting in low processing efficiency
