Low-speed drilling machine with scrap iron protection function

Abstract

The invention discloses a low-speed drilling machine with a scrap iron protection function, and relates to the technical field of machinery, the low-speed drilling machine comprises a drill bit, the drill bit is provided with a bulletproof device, the bulletproof device comprises a knocking plate, the knocking plate is fixedly installed on the outer wall of the drill bit, the drill bit is rotatably installed at the bottom of a control panel, and the bottom of the control panel is rotatably installed on an annular plate; a baffle is rotatably installed on the inner wall of the annular plate, a connecting rod is fixedly installed on the outer wall of the bottom of the annular plate, the bottom of the connecting rod is fixedly installed on the outer wall of a rotating ring, and the outer wall of the rotating ring is rotatably installed at one end of a pull rod. According to the low-speed drilling machine with the scrap iron protection function, a bulletproof device is arranged, a rotating ring drives an iron attraction block to rotate forwards and backwards to achieve the opening and closing effects, when the iron attraction block is closed, scrap iron can be attracted to a conical protection plate through attraction force to offset bounce force, and when the iron attraction block is opened, the attraction force is reduced or even disappears; at the moment, scrap iron can fall down along the diversion trench, and rebounding damage of scrap iron is reduced.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a low-speed drilling machine with iron chip protection function. 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). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates.

Problems solved by technology

[0003] In the prior art, during the process of processing iron workpieces, the drilling machine will generate splashed iron filings. In order to prevent the iron filings from splashing, a protective plate is usually installed, so that the iron filings hit the protective plate during the splashing process. Due to the large mass of iron filings, a rebound force will be generated when it hits the protective plate, and the iron filings will easily bounce back to the workpiece processing place to cause damage to the workpiece, and then affect the processing operation of the drilling machine
