Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool heat dissipation technology, and specifically relates to a heat dissipation device for CNC machine tool processing. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, generally consist of a control medium, a CNC system, a servo system, a power control cabinet, the machine tool body, and various auxiliary devices. They are automated machine tools equipped with a program control system, effectively solving the problem of machining complex, precise, small-batch, and multi-variety parts. Servo motors are frequently used in CNC machine tools; however, servo motors generate a significant amount of heat during operation. If this heat cannot be dissipated in time, it will affect the lifespan of the servo motor. Currently, servo motors typically use self-cooling, but this method has limited cooling capacity. When a large amount of heat is generated, it cannot be dissipated quickly enough, leading to heat buildup and affecting the servo motor's lifespan. Summary of the Invention

[0003] In order to overcome the problem in the prior art that servo motors generate a lot of heat and cannot dissipate it in time, which will affect the life of the motor, this utility model provides a heat dissipation device for CNC machine tool processing.

The heat dissipation box is a hollow square structure with a cover on one side. The motor housing is installed inside the heat dissipation box and connected to the top of the heat dissipation box. The servo motor is installed on one side of the heat dissipation box and passes through the inside of the motor housing. The cooling device is installed at the bottom of the heat dissipation box, and the blower is connected to the cooling device.

[0005] Furthermore, the motor housing is provided with multiple ventilation openings.

[0006] Furthermore, the cover is provided with a through hole that is compatible with the motor shaft.

[0007] Furthermore, the cooling device includes a ventilation box, a ventilation pipe, and an external interface. The ventilation box has an internal hollow structure. The ventilation pipe is installed on the top of the ventilation box and extends into the interior of the ventilation box at its lower end. The external interface is installed on one side of the ventilation box and extends into the interior of the ventilation box, with its end connected to a blower.

[0008] Furthermore, the ventilation duct body is provided with through holes to facilitate airflow.

[0009] The beneficial effects of this utility model are as follows: In this utility model, the blower, heat sink, and cooling device work together to dissipate heat from the servo motor through air cooling, achieving the effect of rapid heat dissipation and cooling of the servo motor, and effectively extending the service life of electrical components in the CNC lathe's power control cabinet.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model discloses a heat dissipation device for CNC machine tool processing. The heat dissipation device mainly includes a heat dissipation box 1, a servo motor 2, a motor housing 3, a blower 4, and a cooling device 5. The heat dissipation box 1 is a hollow square structure with a cover 101 on one side. The motor housing 3 is installed inside the heat dissipation box 1 and connected to the top of the heat dissipation box 1. The servo motor 2 is installed on one side of the heat dissipation box 1, passing through the inside of the motor housing 3. The cooling device 5 is installed at the bottom of the heat dissipation box 1, and the blower 4 is connected to the cooling device 5. This device dissipates heat from the servo motor 2 through air cooling, achieving the effect of cooling down the servo motor 2 and effectively extending the service life of the CNC lathe servo motor 2 component.

[0016] The motor housing 3 is provided with multiple ventilation openings; this structure facilitates the better dissipation of heat generated by the servo motor into the heat sink for absorption.

[0017] The cover 101 has a through hole that matches the shaft of the servo motor 2; when the cover is closed, the shaft can extend to the outside of the heat sink 1 without affecting normal operation.

[0018] The cooling device 5 includes a ventilation box 501, a ventilation pipe 502, and an external interface 503. The ventilation box 501 has an internal hollow structure. The ventilation pipe 502 is installed on the top of the ventilation box 501, and its lower end extends into the interior of the ventilation box 501. The external interface 501 is installed on one side of the ventilation box 501, and its end is connected to the blower 4. This cooling device can ensure that the servo motor 2 dissipates heat smoothly, and the lifespan of the servo motor 2 will not be affected by excessively fast or slow heat dissipation.

[0019] The ventilation duct 502 has through holes to facilitate airflow; this allows for stable airflow and prevents excessive heat dissipation, which could cause frequent temperature fluctuations in the servo motor 2 and affect the stability and reliability of the motor.

[0020] Working process: When the servo motor 2 is working and generates heat, the heat will be dissipated from the ventilation holes on the motor housing 3. At this time, the blower 4, the ventilation box 501, and the ventilation pipe 502 will work together to ventilate and cool the inside of the heat sink 1. The through holes on the ventilation pipe 502 can effectively control the airflow speed and ensure that the air can circulate smoothly. This utility model dissipates heat from the servo motor 2 through air cooling, achieving the effect of rapid heat dissipation and cooling of the servo motor 2, and effectively extending the service life of the CNC lathe servo motor 2 components.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
