Motor heat dissipation structure for machine tool

The present invention relates to a motor, and more particularly to a motor heat dissipation structure for a machine tool.

In the field of today's technology industry, the motor heat dissipation structure is quite commonly used in the heat sink of the machine tool. Generally, the motor of the heat sink object is installed in the machine tool, and the motor is connected to the heat dissipation fan blade, and the motor is cooled when the machine tool is in operation. The heat dissipating fan blade of the structure will be blown toward the machine tool to accelerate the heat dissipation of the machine tool and cool the machine tool. The heat dissipating structure of the motor is as shown in FIG. 1 and FIG. 2, and a machine tool 70 is mounted with a motor 50, one end of the motor 50. A heat dissipating fan blade 60 is mounted, and the heat dissipating fan blade 60 is blown toward the power tool 70 to lower the temperature of the power tool 70. However, the heat dissipating fan blade 60 blows hot air generated by the motor 50 to the machine tool 70. The hot air will expand the machine tool 70, which is inaccurate in size due to expansion.

The utility model provides a motor heat dissipation structure for a machine tool, which aims to solve the problem that the heat dissipation fan blades blow the hot air generated by the motor to the machine tool to expand the machine tool, and the machine tool is inaccurate in size due to expansion.

In order to solve the above-mentioned deficiencies, the present invention provides a motor heat dissipation structure for a machine tool, which is suitable for a machine tool, and the motor heat dissipation structure for the machine tool includes:

a casing having a baffle, a casing and a casing connected to one end of the casing, and the casing is disposed together with an accommodating space, and the baffle is mounted in the accommodating space and has a perforation, the deflector divides the accommodating space into a first space and a second space;

a motor housed in the first space;

A fan is received in the second space and is electrically connected to the motor.

In a preferred embodiment, the plurality of louvers are provided.

Thereby, when the fan rotates, the heat generated by the machine tool and the motor can be discharged from the machine, and the hot air is not blown toward the machine tool, so that the conventional cooling fan blade can blow the hot air to the machine table to cause the machine. The lack of expansion, which in turn improves the dimensional inaccuracy caused by thermal expansion during machine processing.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this new model, please refer to the following for a brief description of the following: Please refer to Figure 3 and Figure 4. This case provides a motor for machine tools. The heat dissipation structure is applicable to a power tool 40. The motor heat dissipation structure of the machine tool comprises: a motor 10 having a plurality of heat dissipation slots 11; a housing 20 having a housing 21 and a baffle 22, the housing The venting hole 211 is provided with a plurality of venting holes 211 and has an accommodating space 221. The accommodating space 221 is provided with the baffle 22, and the direction from the baffle 22 to the heat dissipating holes 211 is a gas. The movement direction X is divided into a first space 221A and a second space 221B by the baffle 22, and a hole 222 is defined in the middle of the baffle 22, and the motor 10 is installed in the first a space 221A has a drive shaft 12 extending from the first space 221A through the through hole 222 to the second space 221B; a fan 30 is received in the second space 221B and The drive shaft 12 of the motor 10 is coupled and driven by the motor 10.

Referring to FIG. 3 and FIG. 4, the motor thermal structure used in the new machine tool is used as follows: when the operator uses the motor heat dissipation structure of the tool machine to dissipate heat from the machine tool 40, the motor 10 drives the fan. 30, the heat in the power tool 40 is moved into the first space 221A, and the heat accumulated in the heat dissipation slots 11 is moved by the fan 30 along the gas moving direction X, when the hot air moves to the When the position of the baffle 22 is at a position, the fan 30 extracts hot air from the through hole 222, moves the hot air from the first space 221A to the second space 221B, and finally causes the heat of the machine tool 40 and the motor 10 to generate Heat is discharged from the heat dissipation holes 211 to achieve heat dissipation.

Therefore, the motor 10 of the present invention is configured to seal the accommodating space 221 by the housing 20, so that the heat accumulated in the accommodating space 221 can be more easily guided when the fan 30 rotates, and the motor is The heat generated by the machine tool 40 and the motor 10 is discharged therefrom, and the hot air is blown toward the machine tool 40, so that the conventional cooling fan blade can blow the hot air to the machine table to cause the machine to expand, and the machine is made. The inaccuracy of the processed dimensions is missing.
