Drilling equipment for heat exchanger tube sheet

Abstract

The invention discloses drilling equipment for a heat exchanger tube sheet. The drilling equipment comprises a machine base, a knob, handles, a dial, the tube sheet, a holding pin, a drill, a rocking handle, a cutting fluid pipe, a plunger, a cutting fluid bath, a filter screen, a rotating platform, a pressing plate, a threaded rod and a machine body; the machine base is located at the lower part of the machine body; the cutting fluid bath is formed in the machine base; the filter screen is arranged in the cutting fluid bath; the filter screen is provided with the rotating platform; the rotating platform is provided with the knob; the rotating platform is provided with the dial; the handles are respectively arranged at two ends of the dial; the dial is provided with the threaded rod; the upper end of the threaded rod is provided with the holding pin; the tube sheet is provided with the pressing plate; the drill is arranged above the pressing plate; the tail part of the drill is provided with the plunger; the right side of the plunger is provided with the cutting fluid pipe; when a circumferential upper hole is processed, only the handles need to be adjusted to enable the drill to move horizontally, and a first hole position is further determined, and the remaining holes are adjusted only by reading the dial, so that the hole alignment time is reduced, and the production efficiency of the tube sheet is increased.

Description

technical field [0001] The invention relates to a drilling device, in particular to a heat exchanger tube plate drilling device. Background technique [0002] Nowadays, heat exchangers have been widely used in production and life, and the demand for heat exchangers in the market is also increasing day by day. However, the equipment used to process the tube plate holes of heat exchangers is the drilling device for processing steel plates. The heat exchanger tube plate itself is porous, and every time a hole is machined, the hole must be aligned once. The production efficiency is low, and it will make people tired after a long time, resulting in a decrease in the position accuracy of the machined hole and a reduction in the production efficiency of the heat exchanger. Contents of the invention [0003] The object of the present invention is to provide a heat exchanger tube sheet drilling device to solve the problems raised in the above-mentioned background technology.
