Description

Air-cooled spindle motor

Technical Field

The utility model relates to an air-cooled spindle motor belongs to electrical equipment technical field.

Background

In the processing operation process of various machine tool equipment, the tool bit rotates at a high speed relative to a machined part to rub, the mutual friction increases the temperature of the tool bit, the tool bit is easily damaged due to overhigh temperature of the tool bit, the precision of the machined part is reduced, and the tool bit is cooled usually. The existing tool bit cooling device is single in structure, cooling liquid can only be sprayed at the position of a tool bit, so that the root of the tool bit cannot be cooled, and the root of the tool bit cannot be cooled for a long time, so that the phenomenon of tool breakage is easy to occur; and the driving part connected with the cutter head is heated up due to the high-speed rotation of the motor during the operation process, and a corresponding cooling device is not arranged. The driving part has too high temperature, which easily causes motor failure and even burning. Therefore, in view of the above problems, those skilled in the art need to improve the existing devices.

Disclosure of Invention

The utility model aims at solving the technical problem of how to cool the cutter and the driving motor in the processing operation process of various machine tool equipment.

In order to solve the problem, the utility model adopts the technical scheme that an air-cooled spindle motor is provided, a motor spindle provided with the motor passes through a drill chuck clamping tool, the two ends of the motor spindle are provided with end covers, one end close to the tool is provided with a front end cover, one end far away from the tool is provided with a rear end cover, the rear end cover is provided with an air inlet, and the front end cover is provided with an exhaust guide hole.

Preferably, a motor casing side wall is arranged between the front end cover and the rear end cover.

Preferably, a cavity for air flow is arranged between the side wall of the motor shell and the motor spindle.

Preferably, two ends of the cavity are respectively communicated with the air inlet on the rear end cover and the exhaust guide hole on the front end cover.

Preferably, the exhaust guide hole is provided as a through hole facing the tool root.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model provides an in the machine tool equipment processing operation in-process, cutter and driving motor refrigerated technical problem, the utility model discloses simple structure is practical, is applicable to multiple application scene, has practiced thrift the cutter cost, has improved the life of motor and cutter.

Fig. 1 is a schematic structural view of the present invention;

reference numerals: 1. an air inlet; 2. a rear end cap; 3. a motor stator; 4. a motor rotor; 5. a front end cover; 6. a drill chuck; 7. an exhaust guide hole; 8. a motor spindle.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings:

as shown in FIG. 1, the present invention provides an air-cooled spindle motor, a motor spindle 8 provided in the motor

The drill chuck 6 is used for clamping a cutter, end covers are arranged at two ends of the motor spindle 8, a front end cover 5 is arranged at one end close to the cutter, a rear end cover 2 is arranged at one end far away from the cutter, an air inlet 1 is arranged on the rear end cover 2, and an exhaust guide hole 7 is arranged on the front end cover 5. A motor casing side wall is arranged between the front end cover 5 and the rear end cover 2. A cavity for air flowing is arranged between the side wall of the motor shell and the motor spindle 8. Two ends of the cavity are respectively communicated with the air inlet 1 on the rear end cover 2 and the exhaust guide hole 7 on the front end cover 5. The exhaust guide hole 7 is a through hole facing the tool root.

As shown in fig. 1, the motor spindle 8 includes a motor stator 3 and a motor rotor 4; when the utility model is used, compressed air is introduced into the motor through the air inlet 1 and then is discharged from the exhaust guide hole 7; the compressed air can fully cool the interior of the motor, and the service life of the motor is prolonged. The compressed air discharged from the exhaust guide hole 7 acts on the drill chuck and the root of the cutter, and is used for cooling the working temperature of the cutter such as a drill bit, a milling cutter and the like, prolonging the service life of the cutter and removing cutting residues on the surface of the cutter.

The foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the present invention in any way and in any way, and it should be understood that modifications and additions may be made by those skilled in the art without departing from the scope of the present invention. Those skilled in the art can make various changes, modifications and evolutions equivalent to those made by the above-disclosed technical content without departing from the spirit and scope of the present invention, and all such changes, modifications and evolutions are equivalent embodiments of the present invention; meanwhile, any changes, modifications and evolutions of equivalent changes to the above embodiments according to the actual technology of the present invention are also within the scope of the technical solution of the present invention.
