Drilling machine with cooling liquid splash-proof function

Abstract

The invention relates to the technical field of drilling machines, and discloses a drilling machine with a cooling liquid splash-proof function, the drilling machine comprises a supporting plate, the front part of the supporting plate is fixedly connected with a mounting plate and a workbench separately, the top of the mounting plate is provided with a water tank and an oil cylinder separately, and the surface of the oil cylinder is in contact with the inner wall of the water tank; an oil cylinder is fixedly connected to the inner wall of the mounting plate, a drilling machine and a fixing plate are fixedly connected to the output end of the oil cylinder, a rotating plate is rotatably connected to the bottom of the fixing plate through a torsional spring, a guide rod is slidably connected to the inner wall of the mounting plate, a limiting disc is fixedly connected to the top end of the guide rod, and a drainage hole is formed in the mounting plate. The oil cylinder drives the fixing plate to move downwards, the fixing plate drives the rotating plate to make contact with a workpiece, then the rotating plate is driven to rotate, the rotating plate can push the guide rod to move upwards, the guide rod pushes the limiting disc to move upwards, the drainage hole communicates with the water tank, cooling liquid can flow down along the guide rod, and therefore the cooling liquid is prevented from splashing.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a drilling machine with a coolant splash prevention function. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, 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, blind holes, and replace special tools. , can be expanded, countersinked, reamed, or tapped. During the processing, the workpiece does not move, the tool moves, the center of the tool is aligned with the center of the hole, and the tool rotates (main movement). The characteristic of the drilling machine is that the workpiece is fixed. Without moving, the tool rotates. [0003] The drilling machine needs to add coolant when drilling holes, and the ...

AI Technical Summary

Problems solved by technology

[0003] The drilling machine needs to add coolant when drilling holes, and the added coolant will collide with the surface of the workpiece and cause splashing. The splashing of the coolant will not only affect the cleaning of the drilling machine, but also cause part of the coolant to be used ineffectively and cause waste. , which in turn affects the cooling effect, so a drilling machine with a coolant splash-proof function is proposed to solve the above-mentioned problems
