Circular temperature reduction type drilling machine

Abstract

The invention discloses a circular temperature reduction type drilling machine. The circular temperature reduction type drilling machine comprises a base, a sliding rod and a supporting plate which are connected in sequence from bottom to top, wherein the supporting plate can slide on the sliding rod; a drill bit box is arranged on the supporting plate in a sliding manner; a drill bit is arrangedon the lower surface of the drill bit box; a water source connection head is arranged on the top of the drill bit box and is connected to a spray head mechanism arranged on the lower surface of the drill bit box by a guide pipe; the spray head mechanism comprises an annular diversion pipe and a plurality of spray heads arranged on the diversion pipe at intervals; and the spray heads are arranged on the annular diversion pipe in a hinging manner. The circular temperature reduction type drilling machine overcomes the problems that as a drilling machine in the prior art generally uses a water pipe connected to a water source for directly reducing the temperature of a machine part, the temperature reduction effect is poor and cooled parts are limited.

Description

technical field [0001] The invention relates to the field of drilling machines, in particular to a circulating cooling type drilling machine. 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). During the processing, the interaction between the drill bit and the workpiece will generate a lot of heat. If the temperature is not cooled in time, it will easily affect the life of the drill bit and the machining accuracy...

Problems solved by technology

[0005] In view of the above technical problems, the purpose of the present invention is to overcome the problem that the drilling machine in the prior art generally uses the water pipe connected to the water source to directly cool the workpiece, but the cooling effect of this structure is poor and the cooling parts are limited, so as to provide a This kind of drilling machine can cool down the workpiece in a cycle, the cooling effect is good, and the cooling is more comprehensive.
