Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and in particular relates to a heat dissipation base for numerical control machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digitally controlled machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The information carrier is input into the CNC device. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing. CNC machine tools will generate a lot of heat during operation. CNC machine tools can dissipate the heat generated during operation by installing a heat dissipation base.

[0003] As disclosed in patent application number CN202320602351.4, a heat dissipation base for CNC machine tools includes a base body, wherein the inner wall of the upper end of the base body is provided with a plurality of heat dissipation grooves, and a partition is installed inside the base body below the heat dissipation groove. When in use, the semiconductor refrigeration plate generates cold energy, and then the cold energy is conducted upward by the cooperation of the cold guide plate and the heat dissipation fins. After the conduction, the air mixed with the cold energy is blown upward by the heat dissipation fan, thereby cooling the inside of the CNC machine tool to improve the safety of the use of the CNC machine tool; at the same time, a partition is added to the lower end of the heat dissipation groove, and after a part of the flying waste chips falls into the partition, it will be discharged into the collection box along the slope of the partition to complete the collection, and a part of it will be gradually discharged into the end with a lower slope (similar to a vibrating feeder) due to the vibration of the vibration motor, thereby realizing the automatic collection operation of the waste chips, and will not affect the use of the heat dissipation device.

[0004] In the existing technology, a partition net is installed to prevent the waste chips generated during machine tool processing from falling into the heat sink base and the waste chips are collected, but there are still shortcomings. First, CNC machine tools usually use auxiliary processing liquids such as cutting fluid during processing. If only the waste chips are collected, some of the liquid generated by the machine tool processing may splash into the heat sink base, causing damage to the heat sink device in the base, thereby making the heat sink base unable to work normally.

[0005] Moreover, the location where heat is generated may change during processing according to different processing tasks. Most existing machine tool heat dissipation bases can basically only cool the entire bottom of the machine tool and cannot adjust the angle of the wind direction, resulting in generally poor cooling effect. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention provides a heat sink for a CNC machine tool. The present invention utilizes triangular folded plates, arc-shaped slots, and a auger rod to collect metal debris and liquid that may fall into the heat sink without affecting the cool air output. Furthermore, the swinging blades allow the direction of the cool air blown out of the heat sink to be controlled.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation base for CNC machine tools, comprising a box body, a plurality of air coolers are arranged at the bottom of the box body, a triangular folding plate is arranged above the air coolers, a wind direction rotation component is arranged above the triangular folding plate at the port of the box body, arc-shaped long grooves are arranged below both sides of the triangular folding plate, an inclined plate is arranged between each of the arc-shaped long grooves and the inner side wall of the box body, a auger rod is rotatably arranged in each of the arc-shaped long grooves, an arc-shaped through hole is arranged on one side of each of the arc-shaped long grooves on the side wall of the box body, and a collection frame is slidably arranged on the outer side wall of the box body.

[0008] Optionally, the wind direction rotation assembly includes a plurality of fixed rods arranged at the port of the box body, a plurality of swing blades are rotatably provided on the plurality of fixed rods, and a connecting rod is rotatably connected to the lower side of the plurality of swing blades.

[0009] Optionally, elastic rubber strips are provided at both ends of the triangular folded plate between the inner side walls of the box body, and a plurality of vibrators are provided on the lower end surface of the triangular folded plate.

[0010] Optionally, a plurality of guide grooves are provided on the upper end surface of the triangular folded plate.

[0012] Optionally, a plurality of second through holes are provided on the side walls of the box body on both sides of the air cooler.

[0013] Optionally, a buffer pad is provided at the upper port of the box.

[0014] In summary, compared with the prior art, the beneficial effects of this solution are:

[0015] (1) The utility model collects metal debris and liquid that may fall into the heat sink without affecting the cold air output of the heat sink through the arrangement of the triangular folding plate, the arc-shaped long groove and the auger rod, thereby effectively preventing the heat sink from being damaged by water and improving the service life of the device;

[0016] (2) The present invention controls the direction of the cold air blown out of the heat dissipation base by arranging the fixed rod, the swing blades and the connecting rod.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a heat dissipation base for a CNC machine tool includes a box body 10, a plurality of air coolers 15 are provided at the bottom of the box body 10, a triangular folding plate 11 is provided above the air cooler 15, arc-shaped long grooves 12 are provided below both sides of the triangular folding plate 11, an inclined plate 13 is provided between each arc-shaped long groove 12 and the inner side wall of the box body 10, a screw rod 14 is rotatably provided in each arc-shaped long groove 12, two motors 27 are provided on one side of the box body 10, and the output end of each motor 27 passes through the side wall of the box body 10 and is fixedly connected to one end of the screw rod 14, an arc-shaped through hole 16 is provided on one side of each arc-shaped long groove 12 on the side wall of the box body 10, the port of the arc-shaped through hole 16 is located on the outer side wall of the box body 10 and a collection frame 17 is slidably provided, and a wind direction rotation component is provided at the port of the box body 10 above the triangular folding plate 11.

[0027] Specifically, the shape of the triangular folded plate 11 is that of a sloping roof house. The debris and liquid generated by CNC machine processing fall to the upper port of the heat dissipation base. The debris and liquid flow along the inclined end surface of the triangular folded plate 11 to the lower end edge of the triangular folded plate 11, and then fall into the inside of the arc-shaped long groove 12.

[0028] The air cooler 15 is an ordinary air cooler, which is an existing technology and will not be elaborated in detail in this solution. The output end of the air cooler 15 can continuously output cold air, which is discharged from the heat dissipation base through the gap between the triangular folded plate 11 and the arc-shaped long groove 12 to cool the CNC machine tool.

[0029] The motor 27 is a common motor. The output end of the motor 27 drives the auger rod 14 to rotate, so that the machine tool processing debris and processing liquid dropped from the arc-shaped long groove 12 are transferred to the inside of the collection frame 17 through the arc-shaped through hole 16 for collection and storage.

[0030] Further, such as Figure 5 and Figure 6 As shown, elastic strips 21 are provided at both ends of the triangular folded plate 11 between the inner side walls of the box body 10 , and a plurality of vibrators 23 are provided on the lower end surface of the triangular folded plate 11 .

[0031] Specifically, the vibrator 23 is an ordinary vibrator, which is an existing technology and will not be elaborated in detail in this solution. The output end of the vibrator 23 drives the triangular folded plate 11 to vibrate, so that the debris adhered to the end surface of the triangular folded plate 11 can quickly fall into the arc-shaped long groove 12, preventing too much debris from adhering to the end surface of the triangular folded plate 11 and accumulating.

[0032] The elastic strip 21 is made of elastic material. The arrangement of the elastic strip 21 prevents the triangular folded plate 11 from vibrating when driven by the vibrator 23 and causes resonance of the box 10 , thereby improving the stability of the device.

[0033] Further, such as Figure 6As shown, a plurality of guide grooves 22 are provided on the upper end surface of the triangular folded plate 11 .

[0034] Specifically, the provision of the plurality of guide grooves 22 facilitates the liquid used in CNC machine tool processing to flow smoothly into the interior of the arc-shaped long groove 12 when the liquid falls onto the end surface of the triangular folded plate 11 .

[0035] Further, such as Figure 1 As shown, a plurality of second through holes 20 are provided on the side walls of the box body 10 on both sides of the air cooler 15 .

[0036] Specifically, the second through hole 20 is a ventilation hole of the heat dissipation base. The provision of the second through hole 20 allows air inside the heat dissipation base to circulate, thereby preventing the base from getting damp and increasing the service life of the device.

[0037] Further, such as Figure 5 As shown, the wind direction rotation assembly includes a plurality of fixed rods 24 arranged at the end of the box body 10, and a plurality of swing blades 25 are rotatably arranged on the plurality of fixed rods 24, and a connecting rod 26 is rotatably connected to the lower part of the plurality of swing blades 25.

[0038] Specifically, the setting of the connecting rod 26 enables the multiple swing blades 25 to rotate synchronously. When operating, the worker only needs to rotate any one swing blade 25, and the multiple swing blades 25 can rotate synchronously to change the direction of the cold air blown out of the heat dissipation base.

[0039] Further, such as Figure 2 and Figure 7 As shown, a plurality of first through holes 18 are provided at the bottom of each collecting frame 17 , and a liquid collecting box 19 is provided below each collecting frame 17 .

[0040] Specifically, the first through hole 18 can separate the liquid and metal debris collected in the collection frame 17. The liquid flows into the liquid collection box 19 through the first through hole 18, thereby achieving the effect of solid-liquid separation, and the metal debris and liquid can be reused.

[0041] The collecting frame 17 is slidably arranged to facilitate cleaning of metal debris inside the collecting frame 17 .

[0042] First, place the CNC machine tool on the upper port of the heat dissipation base, start multiple air coolers 15, and the output end of the air cooler 15 continuously outputs cold air, which is blown into the interior of the CNC machine tool from the bottom through the gap between the triangular folded plate 11 and the arc-shaped long groove 12.

[0043] When the machine tool is processing, metal debris and part of the processing liquid used will fall onto the heat dissipation base. At this time, the metal debris and liquid will flow along the end face of the triangular folded plate 11 to the inside of the arc-shaped long groove 12. Each motor 27 is started, and the output end of the motor 27 drives the auger rod 14 to rotate. The rotation of the auger rod 14 will drive the metal debris and liquid inside the arc-shaped long groove 12 to be transferred to the inside of the collection frame 17. The liquid falling into the collection frame 17 will flow along the first through hole 18 to the inside of the liquid collection box 19 below the collection frame 17 to separate the metal debris and liquid.

[0044] During the above process, if metal debris accumulates on the end surface of the triangular folded plate 11, multiple vibrators 23 are started, and the output end of the vibrator 23 drives the triangular folded plate 11 to vibrate, so that the metal debris on the end surface of the triangular folded plate 11 falls into the inside of the arc-shaped long groove 12.

[0045] If the temperature at one end of the machine tool is too high, any one of the swing blades 25 is rotated to adjust the direction of the cold air blown out from the heat dissipation base to cool down the part with the excessively high temperature. Example 2:

[0046] On the basis of the first embodiment, a further embodiment is made, such as Figure 1 As shown, a buffer pad 28 is provided at the upper end of the box body 10 .

[0047] Specifically, the buffer pad 28 is made of elastic material and is replaceable. The setting of the buffer pad 28 ensures that when the CNC machine tool is placed on the heat dissipation base, there will be no collision or scratches between the two, which effectively protects the CNC machine tool. The buffer pad 28 can also absorb the vibration of the CNC machine tool during operation and prevent the vibration generated by the machine tool from causing the heat dissipation base to resonate, thereby reducing the service life of the heat dissipation base.

[0048] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0049] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0050] The above description shows and describes several preferred embodiments of the present application. However, as previously mentioned, it should be understood that the present application is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present application can be used in various other combinations, modifications, and environments and can be modified within the scope of the application concept described herein through the above teachings or technology or knowledge in the relevant field. Modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present application should be protected by the claims appended hereto.
