Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a workpiece cooling device for machining centers. Background Technology

[0002] During machining, especially in high-precision machining centers, a large amount of heat is generated in the workpiece during cutting, milling, drilling, and other processes. If this heat cannot be dissipated in time, the workpiece temperature will rise, leading to problems such as workpiece deformation, decreased dimensional accuracy, and deterioration of surface quality.

[0003] The related technology, with publication number CN216371355U, describes a high-efficiency cooling boring and milling machining center, comprising: a main body of the boring and milling machining center, an internal water tank, a high-frequency atomizer on the surface of the water tank, a first sleeve support fixedly mounted on the surface of the main body of the boring and milling machining center, the first sleeve support being rotatably connected to a second sleeve support by bolts, a cooling sleeve fixedly mounted on the surface of the second sleeve support, and the cooling sleeve being connected to the high-frequency atomizer through an atomizer bellows. The beneficial effect is that this utility model proposes a high-efficiency cooling boring and milling machining center, which, by adding a high-efficiency atomizing cooling fan, allows the coolant atomized by the high-frequency atomizer to be cooled by the cooling fins during operation, and then blown out by the cooling fan to the surface of the milling cutter and the workpiece. Because the atomized coolant increases the rate of heat absorption, it achieves the purpose of high-efficiency cooling.

[0004] Regarding the workpiece cooling device for machining centers mentioned above, a high-frequency atomizer atomizes the coolant and blows it onto the workpiece through a cooling fan for cooling. However, the atomized coolant in this design can only act on the workpiece in the direction of the fan's blowing, which limits the cooling effect to the fan's direction and makes it difficult to adapt to the needs of workpieces of different sizes and shapes.

The support base provides stable support, the worktable is set on the worktable for positioning and supporting the workpiece to be processed, the machining center performs processing operations above the worktable, the support frame supports the machining center to ensure its stability and accuracy, and the cooling units on both sides are responsible for cooling the workpiece.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a workpiece cooling device for a machining center, including a support base, a worktable surface disposed on the upper end surface of the support base, a machining center disposed relative to the worktable surface, a support frame for supporting the machining center, and refrigeration units respectively disposed on both sides of the worktable surface.

[0010] By adopting the above technical solution, efficient and precise machining and cooling are achieved through the coordinated operation of the support base, worktable, machining center, support frame, and refrigeration units located on both sides of the worktable. Specifically, the refrigeration unit includes a refrigeration component and a drive assembly. The refrigeration component stores cooling fluid in a fluid storage tank, which is atomized by a fluid atomizer and sprayed out through nozzles to cool the machining center and surrounding high-temperature components, effectively controlling the temperature during machining. The drive assembly includes a mounting base fixed to the support base, a rotating shaft, a drive motor, a connecting flange, a rotating disk, a mounting turntable, and an adjustment component. The drive motor drives the rotating disk to rotate via the rotating shaft, which in turn drives the mounting turntable. By adjusting the rotational eccentricity between the mounting turntable and the fluid storage tank, the spray range of the nozzles can adapt to the machining requirements of workpieces of different specifications, ensuring that the cooling effect covers the entire machining area.

[0011] As a preferred embodiment, the fluid storage tank is used to store the cooling medium, and a fluid cooler is provided inside the fluid storage tank. The cooling medium is one of coolant, compressed air, or nitrogen, and the fluid cooler is used to cool the cooling medium.

[0012] By adopting the above technical solution, cooling media such as coolant, compressed air or nitrogen are stored in a fluid storage tank, and then the built-in fluid cooler is used to cool these media to maintain the required low temperature.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

The drive assembly includes a mounting base 6 fixed on the support base 1, a rotating shaft 71, a drive motor 711, a connecting flange 712, a rotating disk 72, a mounting turntable 73, and an adjustment component.
