Inclined multi-hole processing device for special-shaped die castings

Abstract

The invention relates to an inclined multi-hole processing device for special-shaped die castings and aims to solve problems about processing of various holes of the special-shaped die castings. The processing device comprises a fixed base, an inclined bracket at one end of the fixed base and a main power cylinder and is characterized in that a propping device is arranged above the inclined bracket; the propping device comprises a push rod with an air hole; a rigid arc-shaped ladle is arranged at the end part of the push rod; a protective air cushion, of which the area is greater than that of the rigid arc-shaped ladle, is arranged on the surface of the rigid arc-shaped ladle; the fixed base comprises a tool rest guiding device; a multi-purpose tool is arranged in the tool rest guiding device; and the multi-purpose tool comprises a punching die and a multi-angle drilling tool. The processing device provided by the invention provides an effective positioning way for irregular products, and can reduce the positioning times or achieve one-step processing forming for components with a multi-angle hole processing requirement; the punching die and the multi-angle drilling tool are arranged in the processing device so as to satisfy selective use; the universal propping device is better adapted to special-shaped parts such as parts with curved surfaces.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a porous processing device for special-shaped die castings with an inclination angle. Background technique [0002] For special-shaped workpieces, especially products with irregular shapes obtained by casting, injection molding, and die-casting, the hole processing process is more complicated. The main problem comes from positioning, and it is difficult to guarantee the positional relationship of holes, especially long holes. processing. Existing devices generally process long and deep holes for a single hole, and there are few universal solutions for positioning irregular surfaces. For example, the patent publication number is CN104001967A, which discloses a precision micro ultra-long deep hole drilling machine, which utilizes a linear motor and a servo motor with a drill bit on the output shaft to extend or retract the drilling, and this device just abandons trans...

Another example is that the patent notification number is CN202763109U, a special machine for porous processing, including a support, a motor, a gear box and a multi-axis device, and a plurality of drill bits are arranged downwards using the multi-axis device; the motor is axially connected to the gear box, and the gear box is connected to the multi-axis device , and drive the drill bit to rotate; this transmission method has low precision, and the holes are completely fixed

And for the operation that the punching process can be used for the product, it is also unable to cooperate with the drilling synchronous operation

In addition, although there are many positioning designs for dies and irregular workpieces, they all have limitations.
