Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a numerical control machine tool with cooling for machine tool structural parts. Background Art

[0002] A machine tool refers to a machine that manufactures machines. There are various types of machine tools, generally divided into metal cutting machine tools, forging machine tools, drilling machine tools, etc. During the processing of iron parts, a large amount of iron chips will be generated by various machine tools used in the workshop. These iron chips will remain in the processing coolant. At the same time, in order to reduce the temperature of the workpiece during the operation of the machine tool, the coolant is usually sprayed from the nozzles of the spraying device. For example, in a numerical control machine tool coolant filtering device in a Chinese patent, with the patent number (CN218696654U), when cooling the processing position and the drill bit, the support rods on both sides move up and down to adjust the inclination angle of the nozzle, solving the problem that multi-directional spraying cannot be achieved. However, when the drill bit drills deep holes, the sprayed coolant cannot enter the deep holes well, resulting in poor cooling effect and too high temperature of the drill bit, which affects its use. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and a numerical control machine tool with cooling for machine tool structural parts is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a numerical control machine tool with cooling for machine tool structural parts, including a base. The upper end surface of the base is welded with a workbench. A telescopic member is installed on the base. The top of the telescopic member is installed with a drilling motor and a driving motor for driving the telescopic member to extend and retract. The bottom of the drilling motor is provided with a connecting component. The bottom of the connecting component is provided with an inner cylinder. The inner cylinder is connected to the power rod of the drilling motor. The bottom of the connecting component is threadedly connected to a connecting cylinder. The bottom of the connecting cylinder is integrally formed with a drill bit. A plurality of through holes are opened on the outer wall of the drill bit. The outer wall of the inner cylinder is evenly provided with through holes. An installation ring is sleeved on the outer wall of the inner cylinder. The outer wall of the installation ring is connected with a connecting water pipe. The installation ring is communicated with a water pump through the connecting water pipe.

[0006] Preferably, a plurality of through holes are opened on the inner wall of the installation ring. A sealing ring is bonded to the inner wall of the installation ring. The through holes on the inner wall of the installation ring are communicated with the through holes on the outer wall of the inner cylinder.

[0007] Preferably, installation brackets are symmetrically arranged on the upper end surface of the workbench. A plurality of electric cylinders penetrate through the installation brackets. The end of the power rod of the electric cylinder is provided with a clamping block.

[0008] Preferably, the clamping block has a double-layer structure, including a rubber pad on its surface layer and a metal panel on its inner layer.

[0009] Preferably, an annular groove is provided on the outer wall of the inner cylinder, and a convex ring is clamped at the annular groove. A filter cylinder is integrally formed on the convex ring.

[0010] Preferably, the filter cylinder is a flexible cylinder, and the filter cylinder is inserted into the inner cavity of the drill bit.

[0011] Preferably, the through holes are distributed on the drill bit in a downward inclined shape, and the inclination angle is 45°.

[0012] A numerical control machine tool with cooling for machine tool structural parts proposed by the present utility model has the beneficial effects that: by providing an installation ring, the installation ring is communicated with an external water pump through a connecting water pipe. External coolant is injected into the inner cavity of the installation ring through the water pump. Then the coolant enters the connecting cylinder through the water holes provided on the outer wall of the inner cylinder, and then enters the filter cylinder. It enters the inner cavity of the drill bit through the filter holes on the outer wall of the filter cylinder, and then is discharged through the through holes provided on the outer wall of the drill bit. When the drill bit drills a hole, the coolant discharged through the through holes provided on the outer wall of the drill bit directly contacts the drilling point, having a better cooling effect. At the same time, the coolant can be injected into deep holes to adapt to deep holes. Description of the Drawings
