It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present invention provides a cooling device for a horizontal machining center, including: a machine body 1, a bracket 2 is fixedly connected to the inner bottom of the machine body 1; a cooling component 4, the cooling component 4 is fixedly connected to the top of the bracket 2, the cooling component 4 includes a box body 401, a plurality of first springs 407 are fixedly connected to the inner bottom of the box body 401, a pressing plate 408 is fixedly connected between the upper end surfaces of the plurality of first springs 407, a heat conduction pad 409 is arranged on the top of the pressing plate 408, a filling plate 410 is fixedly connected to the bottom of the pressing plate 408, a heat dissipation fin 411 is fixedly connected to the bottom of the filling plate 410, a positioning frame 402 is fixedly connected to the inner surface of the box body 401, the pressing plate 408 is located above the positioning frame 402, hydraulic rods 403 are fixedly connected to the outer surfaces of both sides of the box body 401, the output ends of the hydraulic rods 403 penetrate the box body 401 and extend to the inside, the output ends of the hydraulic rods 403 are fixedly connected to clamping plates 404, the clamping plates 404 are located above the positioning frame 402, a ventilation groove is opened on the inner bottom of the box body 401, a mounting seat 405 is fixedly connected to the inner surface of the ventilation groove, fans 406 are symmetrically fixedly connected to the inner surface of the mounting seat 405, an exhaust duct 3 is fixedly connected to the inner bottom of the machine body 1, the upper end surface of the exhaust duct 3 is fixedly connected to the bottom of the box body 401, the fans 406 are located inside the exhaust duct 3, and the other end of the exhaust duct 3 penetrates the machine body 1 and extends to the outside.

[0023] The effect achieved by the entire Embodiment 1 is that when machining a workpiece on a horizontal machining center, by using the cooling device, after the workpiece is clamped, the workpiece can be cooled during the machining process to avoid deformation of the workpiece due to excessive temperature, which affects the machining quality. When placing the workpiece for clamping, the workpiece is placed inside the box body 401. At this time, the positioning frame 402 provides support for the bottom of the workpiece. Subsequently, the hydraulic rod 403 is started to run and extend. After the hydraulic rod 403 runs, it can drive the clamping plate 404 to move to clamp and fix the workpiece. When the workpiece is placed above the positioning frame 402, the workpiece will exert a downward pressure on the pressing plate 408. The pressing plate 408 will move downward and compress the first spring 407 to contract. At this time, using the resilience of the first spring 407, the pressing plate 408 can be in close contact with the bottom of the workpiece. By using the heat-conducting pad 409 made of a softer material, the heat-conducting pad 409 deforms after being pressed and can be well filled between the bottom of the workpiece and the pressing plate 408, playing a good role in heat conduction. After the workpiece is clamped, the machining center runs to machine the workpiece. At the same time, the fan 406 is started. After the fan 406 runs, it can blow downward. Through the combined use of the filling plate 410 and the heat dissipation fins 411 at the bottom of the pressing plate 408, the heat dissipation fins 411 conduct the heat of the workpiece. Utilizing the characteristic that the heat dissipation fins 411 have a large contact area with the air, the fan 406 can achieve a good cooling effect when running, so that the heat generated when the workpiece is machined is discharged through the exhaust pipe 3, realizing the cooling treatment during the machining process of the workpiece. The cooling of the workpiece can conduct heat in a contact manner for the workpiece, and the cooling effect on the workpiece is good.

[0024] Embodiment 2 is as Figures 1-4 shown. A notch 412 is formed through the heat-conducting pad 409 at the top of the pressing plate 408. A second spring 413 is fixedly connected to the inner bottom of the notch 412. The upper end surface of the second spring 413 is fixedly connected with a temperature measuring piece 414, and the temperature measuring piece 414 is located above the heat-conducting pad 409.

[0025] The effect achieved by the entire Embodiment 2 is that when the workpiece is placed above the pressing plate 408 for machining, the workpiece will contact the surface of the heat-conducting pad 409 and compress the second spring 413 to contract. Using the resilience of the second spring 413, the temperature measuring piece 414 can be closely attached to the bottom of the workpiece. The temperature measuring piece 414 can monitor the temperature of the workpiece in real time. When the temperature of the workpiece is too high and uncontrollable, the machining can be stopped in time to avoid property losses caused by workpiece damage.

[0026] Working principle: When machining a workpiece on a horizontal machining center, by using a cooling device, after the workpiece is clamped, the workpiece can be cooled during the machining process to prevent the workpiece from deforming due to excessive temperature and affecting the machining quality. When placing the workpiece for clamping, the workpiece is placed inside the box body 401. At this time, the positioning frame 402 provides support for the bottom of the workpiece. Subsequently, the hydraulic rod 403 is started to run and extend. After the hydraulic rod 403 runs, it can drive the clamping plate 404 to move to clamp and fix the workpiece. When the workpiece is placed above the positioning frame 402, the workpiece will exert a downward pressure on the pressure plate 408. The pressure plate 408 will move downward and compress the first spring 407 to contract. At this time, by using the resilience of the first spring 407, the pressure plate 408 can be in close contact with the bottom of the workpiece. Through the use of the heat-conducting pad 409 made of a softer material, the heat-conducting pad 409 deforms under pressure and can be better filled between the bottom of the workpiece and the pressure plate 408, playing a better role in heat conduction. After the workpiece is clamped, the machining center runs to machine the workpiece. At the same time, the fan 406 is started. After the fan 406 runs, it can blow downward. Through the combined use of the filling plate 410 and the heat dissipation fins 411 at the bottom of the pressure plate 408, the heat dissipation fins 411 conduct the heat of the workpiece. By using the characteristic that the heat dissipation fins 411 have a larger contact area with the air, a better cooling effect can be achieved when the fan 406 runs. Thus, the heat generated when the workpiece is machined is discharged through the exhaust duct 3, realizing the cooling treatment during the machining process of the workpiece. When the workpiece is placed above the pressure plate 408 for machining, the resilience of the second spring 413 can make the temperature measuring piece 414 closely fit with the bottom of the workpiece. The temperature measuring piece 414 can monitor the temperature of the workpiece in real time. When the temperature of the workpiece is too high and uncontrollable, the machining can be stopped in time to avoid property losses caused by workpiece damage.

[0027] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
