Automatic drilling machine based on PLC (Programmable Logic Controller) control system

Abstract

The invention discloses an automatic drilling machine based on a PLC control system. The key point of the technical scheme is that the automatic drilling machine based on the PLC control system comprises a worktable and a drill bit; a bench clamp for clamping is arranged on the worktable and comprises an upper layer and a lower layer; the upper layer of bench clamp is provided with a drilling hole and is connected with a first cylinder for controlling the drilling hole to be opened or closed; an electromagnetic group is arranged on the worktable; a guide pipe is arranged below the electromagnetic group and is connected with a collecting tank; a screw for controlling the motion of the worktable in X and Y directions is arranged below the worktable; the screw is externally connected with a servo motor for controlling the screw to rotate; the automatic drilling machine also comprises the PLC control system; the PLC control system is used for controlling the worktable and the bench clamp to move. During specific machining, the electromagnetic group is powered on to generate a magnetic force, so the electromagnetic group is capable of generating magnetic attraction on iron scraps, redundant iron scraps generated by machining are attracted to the two sides of the worktable and are guided into the collecting tank, and thus an automatic clearing effect is achieved.

Description

technical field [0001] The present invention relates to a drilling machine, more specifically, it relates to an automatic drilling machine based on a PLC control system. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). [0003] At present, when the drilling machines disclosed on the market are processing iron products, because the workpiece material is brittle, the iron filings generated are easy to splash, and ...

Problems solved by technology

[0003] At present, when the drilling machines disclosed on the market are processing iron products, because the workpiece material is brittle, the iron filings generated are easy to splash, and iron filings are easy to accumulate inside the drill hole, which affects the machining accuracy and further leads to Increased wear on the drill bit
