Curved plate tool and curved plate drilling equipment and drilling method thereof

Abstract

The invention discloses a curved plate tool and curved plate drilling equipment and a drilling method thereof, and belongs to the field of special-shaped plate machining equipment. A to-be-machined workpiece fixed on a back-face fixing workbench adopts an arc-shaped plate with two ends bending upwards, the to-be-machined workpiece is located between a first support and a second support, the upper end of the first support is provided with a back-face pressing mechanism used for pressing one end of the to-be-machined workpiece, the upper end of the second support is provided with a clamping fixture with the height adjustable, and the clamping fixture is used for clamping the other end of the to-be-machined workpiece; a back-face transverse positioning mechanism performs transverse positioning on the to-be-machined workpiece. The curved plate drilling equipment detects the vertical distance between a drilling mechanism and the to-be-machined workpiece in real time through a drilling positioning device, the drilling equipment on a mechanical arm automatically drills the to-be-machined workpiece in the shape of the special-shaped plate, therefore, the working intensity is lowered, the working efficiency is improved, the machining cost is lowered, and the drilling precision is improved. According to the curved plate drilling method, the working mode of a drill bit can be adjusted according to the resistance borne by the drill bit, the life of the drill bit is prolonged, and the working efficiency is improved.

Description

technical field [0001] The utility model relates to a curved plate tooling, drilling equipment and a drilling method thereof, belonging to the field of special-shaped plate processing equipment. Background technique [0002] The structure of the existing equipment when clamping the curved panel is very complex, and a large number of fixtures are often required to position and fix the curved panel. In the process of processing the curved panel, the processing equipment and the fixture are prone to interfere with each other. When drilling the special-shaped plate, due to its curved surface, the existing equipment cannot adapt to the curved surface. For example, in the grain storage production line, it is often necessary to drill holes on the grain blocking door. It is very difficult to drill holes on the arc surface. At present, most of the artificial drilling is used in the market, which is easy to cause personal injury to employees, low production efficiency, and heavy work...

AI Technical Summary

Problems solved by technology

[0002] The structure of the existing equipment when clamping the curved panel is very complicated, and a large number of fixtures are often required to position and fix the curved panel. In the project of processing the curved panel, the processing equipment and the fixture are prone to mutual interference

When drilling special-shaped plates, because the surface is arc-shaped, the existing equipment cannot adapt to the long-term arc-shaped surface. For example, in the grain storage production line, it is often necessary to drill holes on the grain retaining door, because the grain retaining door is a circular arc Shaped structure, it is very difficult to drill holes on the arc surface

At present, most of the holes on the market use manual drilling, which is easy to cause personal injury to employees, low production efficiency, and the workload of the staff is heavy, and the positional accuracy and dimensional accuracy are not guaranteed.
