Description

Technical Field

[0001] This utility model belongs to the technical field of CNC machine tool tool post, specifically relating to a maintenance-free, rapidly cooling power tool post. Background Technology

[0002] The powered tool post is a crucial component of high-end CNC turning centers. Machine tools equipped with powered tool posts can perform multiple machining operations on circumferential surfaces, such as turning, milling, boring, drilling, reaming, and tapping, in a single workpiece clamping, effectively ensuring machining accuracy and efficiency. However, powered tool posts cannot perform continuous high-speed machining and require intermittent operation. Otherwise, overheating can lead to unstable operation, reduced accuracy, and consequently, compromised machining quality and efficiency. Furthermore, high temperatures can cause the mechanical components of the tool post to expand, altering clearances and potentially causing mechanical failures. High temperatures also accelerate the wear and aging of internal materials, shortening the tool post's service life.

[0003] Traditional cooling methods include coolant circulation cooling, fan circulation cooling, and spray cooling. Coolant circulation cooling involves circulating coolant to the cutter head, effectively reducing its temperature and ensuring tool life and quality. Coolant typically consists of water and other additives, which can increase the boiling point and corrosion resistance of water. Its disadvantage is the need for regular coolant checks to ensure cleanliness and level, and timely replacement of contaminated coolant. Fan circulation cooling uses a fan to blow air onto the cutter head, carrying away heat and lowering its temperature. This method is simple and easy to implement, and also reduces mechanical stress on the machine. However, the disadvantage is the need to properly control the airflow to avoid affecting cooling efficiency and machine stability. Spray cooling uses a fan to atomize water and blow it onto the forgings for cooling. It is suitable for applications requiring rapid cooling, but the disadvantage is the need for frequent cleaning of foreign objects and maintaining a clean environment around the machine to prevent obstruction of the fan's operation.

[0016] The present invention will now be described in further clear and complete detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0019] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0022] This utility model relates to a maintenance-free, rapidly cooled power tool holder, such as... Figure 1-2 As shown, the device includes a tool holder housing 1, a cooling pipe 2, and a tool disc 3 connected to the tool holder housing 1. The cooling pipe 2 has a compressed air inlet 4, a hot air outlet 5, and a cold air outlet 6 connected to the compressed air inlet 4. The hot air outlet 5 and the cold air outlet 6 are located at the left and right ends of the cooling pipe 2, respectively. The hot air outlet 5 is equipped with a regulating valve 7, which has a manual adjustment knob. The temperature and flow rate of the cold air can be manually adjusted. The lower the coefficient of performance (COP) is adjusted using the knob, the lower the temperature of the cold air. The cold air outlet 6 is connected to the cold air pipe 9 on the tool holder housing 1, and the cold air outlet 6 is provided with an elastic joint that elastically abuts against the cooling channel 8 on the tool disc 3. Specifically, the elastic joint includes a valve core 10 provided on the cold air pipe 9 and a compression spring 11 for pressing the valve core 10 against the tool disc 3. The tool disc 3 is provided with multiple cooling channels 8. The inlet end of the cooling channel 8 elastically abuts against the outlet end of the elastic joint, and after the inlet end of each cooling channel 8 rotates to the working position with the tool disc 3, the working position coincides with the position of the outlet end of the elastic joint.

[0023] When this utility model relates to a maintenance-free, rapidly cooling power tool holder, compressed air with a certain pressure enters the cooling pipe 2 and expands and accelerates. The accelerated airflow rotates at high speed inside the cylindrical cooling pipe 2. The rotating airflow enters the interior of the heat pipe along the heat pipe wall. After energy exchange, the airflow inside the heat pipe is separated into two streams: one is a hot airflow, and the other is a cold airflow. At the end of the heat pipe, part of the compressed air is discharged as hot air through the regulating valve 7. The remaining compressed air returns at a lower speed through the center of the rotating airflow entering the heat pipe. This cold airflow forms ultra-low temperature cold air through the center of the generator and gathers at the cold air outlet 6, entering the cold air pipe 9 of the tool holder housing. The compression spring 11 presses the valve core 10 tightly onto the cooling channel 8 of the tool disc 3. Even after the tool disc 3 is rotated, cold air can still be sent into the interior of the tool disc 3 at each station to cool the tool holder.

[0024] In summary, the maintenance-free, rapidly cooling power tool holder provided by this utility model has a simple structure, is easy to use, requires no maintenance, does not require coolant, does not require regular cleaning of the coolant, and does not require regular maintenance. Furthermore, it does not require deliberately keeping the area around the machine clean during tool holder cooling. Simultaneously, the cooling temperature is extremely low and adjustable, reaching as low as -45°C, which can rapidly cool the tool disc with excellent cooling effect. This effectively improves the processing accuracy and efficiency of the product, has significant market value, and is worthy of widespread promotion and application.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
