Abstract

The invention discloses a numerical control planar drill with a main shaft cooling device, belongs to drilling mechanical equipment, and particularly relates to a numerical control planar drill with a cooling device. The numerical control planar drill with the main shaft cooling device comprises a motor, an upper bearing pressing cover, a drilling power head box, a lower bearing pressing cover, a main shaft and a drilling cutter, wherein the motor, the upper bearing pressing cover, the drilling power head box, the lower bearing pressing cover, the main shaft and the drilling cutter are sequentially connected from top to bottom. The numerical control planar drill is characterized in that the two sides of the upper bearing pressing cover are provided with a left cooling water tank and a right cooling water tank respectively, and the left cooling water tank is communicated with the right cooling water tank. Due to the fact that the side face of the main shaft is provided with the cooling device, heat produced by high-speed rotation speed of bearings is dissipated through cooling fluids according to a flowing circulation theory, heat of lubrication oil cannot be exceedingly high, the situation that the bearings are damaged due to excessive heat produced by high-speed operation is avoided, the service life of the bearings is greatly prolonged, and compared with an existing numerical control planar drill, the numerical control planar drill has the advantages of being high in stability and safety and long in service life.

Description

Numerical control plane with main shaft cooling device bores
Technical field
The invention belongs to drilling plant equipment, particularly bore with the numerical control plane of cooling device.
Background technology
It is conventional machining equipment that numerical control plane bores, and the main shaft that existing numerical control plane bores is not with cooling device, under equipment work high speed rotating speed, the main shaft bearing generation heat that runs up, lubricating oil heats up, and cannot dispel the heat away, bearing is fragile, directly affects the service life of equipment.
Summary of the invention
There is no cooling device in order to overcome existing numerical control plane brill, dispel the heat bad, the flimsy deficiency of bearing, the invention provides a kind of numerical control plane with main shaft cooling device and bores, this numerical control plane with main shaft cooling device bores and can bore main shaft to plane and carry out coolingly, prevents its excess Temperature.
The technical solution adopted for the present invention to solve the technical problems is: a kind of numerical control plane with main shaft cooling device bores, comprise from top to bottom connected successively motor, upper bearing (metal) gland, drill unit casing, lower bearing gland, main shaft, drilling cutters, it is characterized in that: be separately installed with the left side cooling water tank, the right side cooling water tank that are interconnected in upper bearing (metal) gland both sides.
Described left side cooling water tank or the casing of right side cooling water tank are provided with cooling fluid groove near main shaft one side, another side is plane, make to be fixed by bolts to plane and bore both sides, the below of casing is provided with water inlet top and is provided with delivery port, the water inlet of left side cooling water tank is cooling liquid inlet, the delivery port of this water tank is connected with the water inlet of right side cooling water tank by connecting water pipe, and the delivery port of right side cooling water tank is cooling liquid outlet.
The invention has the beneficial effects as follows the groove at side surface fit on cooling fluid cooling device of main shaft device, cooling fluid utilize flow circuit principle by bearing because of high speed rotating speed produce dissipation of heat go out, make the heat of lubricating oil can be not too high, avoid producing too high heat because running up and make bearing damage, bearing life is greatly improved, at main shaft both sides dress cooling device, utilize the circulation feature of low in and high out that dissipation of heat is gone out.Comparing with existing numerical control plane brill, it is high, safe to have stability, the advantage of long service life.
