Description

Technical Field

[0001] This utility model relates to the field of optomechanical technology for vertical machining centers, and in particular to a high-efficiency heat dissipation cooling component for optomechanical systems in vertical machining centers. Background Technology

[0002] The optical mechanism of a vertical machining center is the core basic mechanical structure of the vertical machining center. It refers to a semi-finished machine tool that has completed the machining and assembly of key mechanical components such as the main frame, transmission system, and guiding system, but has not integrated functional peripherals such as electrical control system, hydraulic or pneumatic system, cooling system, tool magazine, and protective cover.

[0003] In the operation of the optical mechanism in a vertical machining center, a lifting mechanism is required. Currently, the existing lifting mechanisms of the optical mechanism in machining centers lack a stable transmission structure and have limited balancing capabilities, which is not conducive to lifting. At the same time, the existing lifting structure of the machining center is relatively simple and lacks an auxiliary lifting structure, which is not conducive to the lifting of the machining center and affects the balanced operation of the machining center spindle.

[0004] The existing patent (publication number: CN213889231U) discloses a vertical machining center optical-mechanical lifting and balancing device. In this utility model, a transmission motor drives a lead screw to rotate, the lead screw acts on the connecting table to move, the connecting table drives the slide to move, and the slide drives the mounting table to move, which is beneficial for the lifting and lowering of the machining center. Through the cooperation of the slide and the slide rail, the slide moves stably on the column, which facilitates the lifting and balancing of the mounting table and the spindle motor, and ensures the stability of the lifting structure.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the spindle motors of some existing vertical machining center optical machines lack efficient heat dissipation structures. Especially when the vertical machining center optical machine operates continuously in a factory with high ambient temperatures, the temperature difference between the spindle motor and the surrounding environment will decrease, reducing the heat dissipation efficiency of the spindle motor and making it prone to overheating, which will affect machining accuracy and service life.

[0006] To address this, a high-efficiency heat dissipation optical-mechanical cooling component for vertical machining centers is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency heat dissipation cooling component for vertical machining centers, which can solve the problem that the spindle motor of some existing vertical machining centers does not have a high-efficiency heat dissipation structure. Especially when the vertical machining center operates continuously in a factory with a high ambient temperature, the temperature difference between the spindle motor and the surrounding environment will decrease, resulting in a reduction in the heat dissipation efficiency of the spindle motor and an easy occurrence of overheating, which affects the machining accuracy and service life.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation vertical machining center optomechanical cooling assembly, comprising a vertical machining center optomechanical body, a movable base and a spindle motor body, wherein a flow guide shroud is provided on the top of the movable base, a heat dissipation mechanism is provided inside the flow guide shroud, and a protective mechanism is provided on the front side of the heat dissipation mechanism;

[0009] The heat dissipation mechanism includes several heat sinks, two fixing rings, two through holes, and two fans. The heat sinks are evenly distributed on the top and both sides of the inner wall of the air guide. The through holes are opened on the front side of the air guide. The rear side of the fixing rings is fixedly connected to the front side of the air guide. The through holes are connected to the fixing rings. The fans are fixedly connected to the inner wall of the fixing rings.

[0010] Preferably, the protective mechanism includes two first magnetic strips, a fixed frame, and a protective net. The protective net is fixedly connected to the inner wall of the fixed frame, the front side of the first magnetic strip is fixedly connected to the rear side of the fixed frame, and the rear side of the protective net is in contact with the front side of the fixed ring.

[0011] Preferably, a second magnetic strip is fixedly connected to both sides of the front side of the air guide, and the rear side of the first magnetic strip is magnetically attracted to the front side of the second magnetic strip.

[0012] Preferably, pull blocks are fixedly connected to both the top and bottom of the fixed frame.

[0013] Preferably, both the air guide and the heat sink are made of aluminum, and the surface of the heat sink is in contact with the surface of the spindle motor body.

[0014] Preferably, a connecting frame is fixedly connected to the surface of the movable seat, and the flow guide is movably inserted into the inside of the connecting frame.

[0015] Preferably, a connecting button is provided on both sides of the connecting frame, and a connecting hole is provided on the front and rear sides of both sides of the connecting frame. The connecting button passes through the connecting frame and extends into the interior of the connecting hole on the side of the connecting frame closer to it, and the connecting button is threaded into the interior of the connecting frame.

[0016] Preferably, a lifting ring is fixedly connected to the top of the flow guide.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a heat dissipation mechanism with an aluminum air guide and heat sinks as the core heat-conducting components. The excellent thermal conductivity of aluminum can quickly absorb the heat generated by the spindle motor body during operation. The heat sinks are evenly distributed on the top and sides of the inner wall of the air guide, which can fully contact the surface of the spindle motor body to expand the heat absorption area. With the help of a fan fixed to the inner wall of the fixing ring, the fan sends high-speed air into the air guide through the fixing ring which is connected to the through hole of the air guide. The high-speed air diffuses in the gap between the air guide and the spindle motor body, and then passes through the gaps of multiple heat sinks to quickly remove the absorbed heat, effectively improving the heat dissipation efficiency of the spindle motor body. Even in a high-temperature factory environment, it can ensure that the spindle motor body maintains the normal operating temperature and avoids the impact on processing accuracy and service life due to insufficient heat dissipation.

[0019] 2. This application incorporates a protective mechanism that uses a protective mesh on the inner wall of the fixed frame to block external debris, preventing it from entering the air guide shroud through the through-holes and interfering with the fan's operation. The first magnetic strip on the rear side of the fixed frame and the second magnetic strip on the front side of the air guide shroud magnetically engage to achieve a stable connection between the fixed frame and the air guide shroud. At the same time, the pull-block design at the top and bottom of the fixed frame facilitates the disassembly and installation of the protective mesh, making it convenient for subsequent cleaning of the protective mesh and fan maintenance, and ensuring the long-term stable operation of the heat dissipation mechanism.

[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 The present invention provides the following technical solution:

[0031] A high-efficiency heat dissipation vertical machining center optical engine cooling assembly includes a vertical machining center optical engine body 1, a movable base 2 and a spindle motor body 4. A flow guide 3 is provided on the top of the movable base 2, a heat dissipation mechanism 9 is provided inside the flow guide 3, and a protective mechanism 7 is provided on the front side of the heat dissipation mechanism 9.

[0032] The heat dissipation mechanism 9 includes several heat sinks 901, two fixing rings 902, two through holes 903 and two fans 904. The heat sinks 901 are evenly distributed on the top and both sides of the inner wall of the air guide shroud 3. The through holes 903 are opened on the front side of the air guide shroud 3. The rear side of the fixing rings 902 is fixedly connected to the front side of the air guide shroud 3. The through holes 903 are connected to the fixing rings 902. The fans 904 are fixedly connected to the inner wall of the fixing rings 902.

[0033] In this embodiment: the air guide shroud 3 is inserted into the connecting frame 5 of the movable base 2 by holding the lifting ring 11, and the connecting button 6 is rotated to make it enter the connecting hole 8, thus completing the connection between the air guide shroud 3 and the connecting frame 5. At this time, the heat sink 901 on the inner wall of the aluminum air guide shroud 3 contacts the main spindle motor body 4, quickly absorbing its working heat. After the fan 904 is powered by an external power supply, it is started by an external controller. The high-speed air generated by the fan 904 enters the air guide shroud 3 through the through hole 903, passes through the gap of the heat sink 901, and carries away the heat. In the protective mechanism 7, the protective net 703 prevents debris from entering the fan 904, protecting the fan 904 to work normally. The first magnetic strip 70 of the fixed frame 702... The second magnetic strip 10 of the guide shroud 3 is magnetically fixed, which facilitates the positioning of the fixing frame 702 and the protective net 703 on the front side of the fan 904. The pull block 12 facilitates the disassembly and maintenance of the protective net 703. In factories with high ambient temperatures, it can achieve efficient heat dissipation of the spindle motor body 4, ensuring machining accuracy and the life of the spindle motor body 4. It solves the problem that the spindle motor of some existing vertical machining center optical machines does not have an efficient heat dissipation structure. Especially when the vertical machining center optical machine is working continuously in a factory with high ambient temperature, it will reduce the temperature difference between the spindle motor and the surrounding environment, which will reduce the heat dissipation efficiency of the spindle motor and easily lead to overheating, affecting machining accuracy and service life.

[0034] Specifically, such as Figure 6 As shown, the protective mechanism 7 includes two first magnetic strips 701, a fixed frame 702 and a protective net 703. The protective net 703 is fixedly connected to the inner wall of the fixed frame 702. The front side of the first magnetic strips 701 is fixedly connected to the rear side of the fixed frame 702, and the rear side of the protective net 703 is in contact with the front side of the fixed ring 902.

[0035] Specifically, such as Figure 3 and Figure 6 As shown, the front sides of the flow guide 3 are fixedly connected with the second magnetic strip 10, and the rear side of the first magnetic strip 701 is magnetically attracted to the front side of the second magnetic strip 10.

[0036] Specifically, such as Figure 6 As shown, pull blocks 12 are fixedly connected to both the top and bottom of the fixed frame 702.

[0037] In this embodiment: the protective mechanism 7 can block debris from entering through the protective net 703, so as to avoid affecting the operation of the fan 904. The first magnetic strip 701 and the second magnetic strip 10 magnetically cooperate to make the fixed frame 702 securely installed and easy to disassemble and assemble. The design of the pull block 12 further facilitates the disassembly and cleaning of the protective net 703.

[0038] Specifically, such as Figure 5 and Figure 8As shown, both the flow guide shroud 3 and the heat sink 901 are made of aluminum, and the surface of the heat sink 901 is in contact with the surface of the spindle motor body 4.

[0039] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a connecting frame 5 is fixedly connected to the surface of the movable seat 2, and the flow guide 3 is movably inserted into the inside of the connecting frame 5.

[0040] In this embodiment: the aluminum guide shroud 3 and the heat sink 901 have excellent thermal conductivity. The heat sink 901 can efficiently absorb heat when in contact with the spindle motor body 4. The guide shroud 3 is movably inserted into the connecting frame 5, which facilitates quick installation and positioning. The structure is reasonably designed.

[0041] Specifically, such as Figure 4 and Figure 7 As shown, there are connecting buttons 6 on both sides of the connecting frame 5. Connecting holes 8 are opened on the front and rear sides of both sides of the connecting frame 5. The side of the connecting button 6 near the connecting frame 5 passes through the connecting frame 5 and extends into the interior of the connecting hole 8. The connecting button 6 is threaded into the interior of the connecting frame 5.

[0042] Specifically, such as Figure 5 As shown, a lifting ring 11 is fixedly connected to the top of the flow guide 3.

[0043] In this embodiment: by rotating the connecting button 6, the connecting button 6 can be moved into the connecting hole 8, so that the flow guide 3 and the connecting frame 5 can be stably connected. The lifting ring 11 is designed to facilitate the movement of the flow guide 3 for installation.

[0044] Working principle: First, using the connecting frame 5 fixed to the surface of the movable base 2, the guide shield 3 is moved by holding the lifting ring 11 to the inside of the connecting frame 5. Then, the connecting button 6, which is threaded inside the connecting frame 5, is rotated to move the connecting button 6 into the connecting hole 8, thus connecting the guide shield 3 and the connecting frame 5 together. Since both the guide shield 3 and the heat sink 901 are made of aluminum, and the heat sink 901 is evenly distributed on the top and sides of the inner wall of the guide shield 3, the aluminum heat sink 901 will contact the surface of the spindle motor body 4. When the spindle motor body 4 generates heat during operation, the heat will be quickly absorbed by the aluminum heat sink 901 and the aluminum guide shield 3, which have good thermal conductivity. Then, the fan 904 is powered by an external power supply, and the fan 904 is powered by an external power supply. The fan 904 is controlled by an external controller. The fan 904 is fixedly connected to the inner wall of the fixing ring 902. The rear side of the fixing ring 902 is fixedly connected to the front side of the air guide shroud 3 and communicates with the through hole 903 on the front side of the air guide shroud 3. Therefore, the high-speed airflow generated by the fan 904 enters the air guide shroud 3 through the through hole 903. There is a gap between the front side of the inner wall of the air guide shroud 3 and the spindle motor body 4. The high-speed airflow passes through the gaps between the multiple heat sinks 901, thereby quickly removing the heat generated by the spindle motor body 4 during operation and improving the heat dissipation efficiency of the spindle motor body 4. During the operation of the fan 904, the protective mechanism 7 on the front side provides protection. The protective mesh 703 in the protective mechanism 7 is fixed... The protective net 703, attached to the inner wall of the fixed frame 702, prevents external debris from entering the guide shroud 3 through the through hole 903, thus avoiding impact on the operation of the fan 904 or damage to the main shaft motor body 4. The rear side of the protective net 703 contacts the front side of the fixed ring 902, preventing debris from contacting the fan 904 through the gap between the protective net 703 and the fixed ring 902. The first magnetic strip 701 fixedly connected to the rear side of the fixed frame 702 magnetically attracts the second magnetic strips 10 fixed on both sides of the front side of the guide shroud 3, achieving a stable connection between the fixed frame 702 and the guide shroud 3. Simultaneously, the pull blocks 12 fixed to the top and bottom of the fixed frame 702 facilitate the disassembly and installation of the protective net 703 for cleaning or maintenance of the fan 904, especially in vertical applications. When the vertical machining center's optical machine body 1 operates in a factory environment with high ambient temperatures, it can achieve efficient heat dissipation for the spindle motor body 4, ensuring the normal operating temperature of the spindle motor body 4, thereby guaranteeing machining accuracy and extending the service life of the spindle motor body 4. This solves the problem that some existing vertical machining center optical machines lack efficient heat dissipation structures for their spindle motors. Especially when the vertical machining center optical machine operates continuously in a factory environment with high ambient temperatures, the temperature difference between the spindle motor and the surrounding environment decreases, reducing the spindle motor's heat dissipation efficiency and easily leading to overheating, which affects machining accuracy and service life. It should be noted that the vertical machining center optical machine body 1, spindle motor body 4, and fan 904 are all existing, published, and mature technologies.Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art, and will not be elaborated upon here.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
