Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for a vertical machining center. Background Technology
[0002] A vertical machining center is a type of CNC machine tool in which the spindle axis is set perpendicular to the worktable. Vertical machining centers are usually evolved from vertical milling machines and have a variety of cutting functions, such as milling, drilling, and tapping, and can complete multiple machining operations in a single setup.
[0003] According to Chinese patent CN210173123U, a cooling device for a vertical machining center is proposed. In this device, a cooling ring is set up, which can seamlessly connect the spindle motor and the contact aluminum plate through thermally conductive silicone, thereby achieving better heat conduction and heat dissipation, and improving the service life of the spindle motor. Through the set rotating central shaft, the rotating central shaft can simultaneously drive the circulation pump and the blower to rotate through the set rotating shaft and the drive gear. This can save more motor installation costs and improve the utilization efficiency of the spindle motor.
[0004] However, this patent still has some shortcomings. The device uses a rotating blower to quickly dissipate the heat from the fin surface, thereby reducing the temperature of the internal coolant and facilitating its discharge, thus achieving rapid heat dissipation for the spindle motor. However, since the blower is always in a fixed position, during the process of blowing air to cool the spindle motor, some areas on the surface of the spindle motor may not be adequately cooled, which affects the utilization efficiency of the spindle motor and the cooling effect of the device. Therefore, we propose a cooling device for vertical machining centers. Utility Model Content
[0005] The purpose of this invention is to provide a cooling device for a vertical machining center, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a vertical machining center, comprising a machine body, a support frame fixedly connected to the inner wall of the side of the machine body, a spindle motor fixedly connected to the inner wall of the support frame, and a blowing assembly disposed inside the machine body. The blowing assembly includes a support seat fixedly connected to the top of the inner wall of the machine body, a forward and reverse motor fixedly connected to the inner wall of the support seat, a bidirectional threaded rod fixedly connected to the output end of the forward and reverse motor, a sleeve block threadedly connected to the outer wall of the bidirectional threaded rod, a rotating block movably connected to the outer wall of the sleeve block via a hinge, a displacement block movably connected to the other end of the rotating block via a hinge, a pressing column fixedly connected to the side wall of the displacement block, a drive motor fixedly connected to the outer wall of the rotating block, an output shaft fixedly connected to the output end of the drive motor, and blowing blades fixedly connected to the outer wall of the other end of the output shaft. By setting the blowing assembly, it is convenient to uniformly blow air into the interior of the machine body through the blowing blades, thereby improving the cooling effect on the spindle motor and facilitating air blowing cooling at different positions of the spindle motor.
[0007] Preferably, the blowing assembly further includes a ventilation plate slidably connected to the other end of the extrusion column. The outer wall of the ventilation plate is slidably connected to the inner wall of the machine body. A horizontal column is slidably connected to the inner side wall of the ventilation plate. A vertical block is fixedly connected to the side wall of the horizontal column. The top of the vertical block is fixedly connected to the top of the inner wall of the machine body. A spring is fixedly connected to the side wall of the vertical block. The other end of the spring is fixedly connected to the side wall of the ventilation plate. When the rotating block rotates, it will cause the displacement block to move. After the displacement block moves, it will carry the extrusion column to extrude. During the movement of the extrusion column, it will extrude the ventilation plate, causing the ventilation plate to slide along the outer wall of the horizontal column and compress the spring. This facilitates the extrusion of cold air blown out by the blowing blades through the ventilation plate, and facilitates uniform cooling of the main shaft motor.
[0008] Preferably, the side wall of the ventilation plate is provided with a cooling assembly, which includes a coolant storage tank fixedly connected to the side wall of the ventilation plate. A condenser pipe is connected to the bottom of the coolant storage tank, and a fixing block is fixedly connected to the outer wall of the other end of the condenser pipe. The side wall of the fixing block is fixedly connected to the side wall of the ventilation plate. By setting up the cooling assembly, during the blowing process of the blower blades, the operator can start the coolant storage tank to allow the coolant inside the coolant storage tank to flow into the interior of the condenser pipe, causing cold air to be generated on the outer wall of the condenser pipe. When the blower blades blow air, the cold air will be blown out, thereby facilitating the cooling of the spindle motor.
[0009] Preferably, the bottom of the machine body is fixedly connected to a bracket, and there are two brackets. The two brackets are symmetrically distributed along the center plane of the machine body. By setting two brackets, it is easy to achieve a stable support for the machine body.
[0010] Preferably, the blower blades are divided into two groups, both groups of blower blades are located on the side of the ventilation plate, and the two groups of blower blades are symmetrically distributed along the center plane of the bidirectional threaded rod.
[0011] Preferably, the outer wall of the horizontal column is adapted to the inner side wall of the ventilation plate, and the end face of the horizontal column is fixedly connected to the side wall of the vertical block.
[0012] This utility model provides a cooling device for a vertical machining center. This cooling device for a vertical machining center has the following advantages:
[0013] The cooling system of this vertical machining center generates a significant amount of heat on the outer wall of the spindle motor during prolonged operation, necessitating cooling. The operator activates the drive motor, causing the output shaft to rotate. This rotation carries the air blower blades, which in turn cool the spindle motor. Subsequently, the operator activates the forward and reverse motors, causing the bidirectional threaded rod to rotate. This rotation moves two sleeve blocks closer together, which in turn causes the rotating block... The rotating block rotates, causing the drive motor to rotate as well. This facilitates uniform airflow inside the machine body, improving the cooling effect on the main spindle motor and allowing for targeted cooling of different parts of the main spindle motor. As the rotating block rotates, it causes the displacement block to move, which in turn causes the extrusion column to press. During the movement of the extrusion column, the ventilation plate is pressed, causing it to slide along the outer wall of the horizontal column and compress the spring. This allows the ventilation plate to press the cold air blown out by the air blower blades, facilitating uniform cooling of the main spindle motor.
[0014] The cooling device of this vertical machining center, by setting up cooling components, allows the operator to activate the coolant storage tank during the blowing process of the blower blades. This allows the coolant inside the coolant storage tank to flow into the interior of the condenser tube, causing cold air to be generated on the outer wall of the condenser tube. When the blower blades blow air, the cold air is blown out, thus facilitating the cooling of the spindle motor. Attached Figure Description

[0020] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0021] A preferred embodiment of the cooling device for a vertical machining center provided by this utility model is, for example... Figures 1 to 4The following describes a cooling device for a vertical machining center: A machine body 1, a support frame 2 fixedly connected to the inner wall of the side of the machine body 1, a spindle motor 3 fixedly connected to the inner wall of the support frame 2, and a blower assembly 51 disposed inside the machine body 1. The blower assembly 51 includes a support base 511 fixedly connected to the top of the inner wall of the machine body 1, a reversible motor 512 fixedly connected to the inner wall of the support base 511, a bidirectional threaded rod 513 fixedly connected to the output end of the reversible motor 512, a sleeve block 514 threadedly connected to the outer wall of the bidirectional threaded rod 513, a rotating block 515 movably connected to the outer wall of the sleeve block 514 via a hinge, a displacement block 516 movably connected to the other end of the rotating block 515 via a hinge, a pressing column 517 fixedly connected to the side wall of the displacement block 516, a drive motor 518 fixedly connected to the outer wall of the rotating block 515, an output shaft 519 fixedly connected to the output end of the drive motor 518, and a blower blade 5110 fixedly connected to the outer wall of the other end of the output shaft 519. The blower assembly 51 is installed. During long-term operation, the outer wall of the spindle motor 3 generates a large amount of heat, thus requiring cooling. At this time, the operator turns on the drive motor 518 to rotate the output shaft 519. During the rotation of the output shaft 519, the blower blades 5110 will also rotate, facilitating the cooling of the spindle motor 3. Subsequently, the operator turns on the forward and reverse motor 512 to rotate the bidirectional threaded rod 513. After the bidirectional threaded rod 513 rotates, it will move the two socket blocks 514 closer together. After the two socket blocks 514 move relative to each other, they will cause the rotating block 515 to rotate. When the rotating block 515 rotates, it will cause the drive motor 518 to rotate, thus facilitating uniform airflow into the interior of the machine body 1, thereby improving the cooling effect of the spindle motor 3 and facilitating airflow cooling at different locations of the spindle motor 3.
[0022] The blower assembly 51 also includes a ventilation plate 5111 slidably connected to the other end of the extrusion column 517. The outer wall of the ventilation plate 5111 is slidably connected to the inner wall of the body 1. A horizontal column 5112 is slidably connected to the inner side wall of the ventilation plate 5111. A vertical block 5113 is fixedly connected to the side wall of the horizontal column 5112. The top of the vertical block 5113 is fixedly connected to the top of the inner wall of the body 1. A spring 5114 is fixedly connected to the side wall of the vertical block 5113. The other end of the spring 5114 is fixedly connected to the side wall of the ventilation plate 5111. The fixed connection is such that when the rotating block 515 rotates, it will cause the displacement block 516 to move. After the displacement block 516 moves, it will carry the extrusion column 517 to extrude. During the movement of the extrusion column 517, it will extrude the ventilation plate 5111, causing the ventilation plate 5111 to slide along the outer wall of the horizontal column 5112 and compress the spring 5114. This makes it easier to extrude the cold air blown out by the blower blade 5110 through the ventilation plate 5111, which facilitates uniform cooling of the main shaft motor 3.
[0023] A preferred embodiment of the cooling device for a vertical machining center provided by this utility model is, for example... Figures 1 to 4 As shown: A cooling assembly 52 is provided on the side wall of the ventilation plate 5111. The cooling assembly 52 includes a coolant storage tank 521 fixedly connected to the side wall of the ventilation plate 5111. A condenser pipe 522 is connected to the bottom of the coolant storage tank 521. A fixing block 523 is fixedly connected to the outer wall of the other end of the condenser pipe 522. The side wall of the fixing block 523 is fixedly connected to the side wall of the ventilation plate 5111. By setting the cooling assembly 52, during the blowing process of the blower blades 5110, the operator can start the coolant storage tank 521 to allow the coolant inside the coolant storage tank 521 to flow into the interior of the condenser pipe 522, causing cold air to be generated on the outer wall of the condenser pipe 522. When the blower blades 5110 blow air, the cold air will be blown out, thereby facilitating the cooling of the spindle motor 3.
[0024] Furthermore, the bottom of the body 1 is fixedly connected to a bracket 4. There are two brackets 4, which are symmetrically distributed along the center plane of the body 1. By setting two brackets 4, it is easy to achieve stable support for the body 1.
[0025] Furthermore, the blower blades 5110 are divided into two groups, both groups of blower blades 5110 are located on the side of the ventilation plate 5111, and the two groups of blower blades 5110 are symmetrically distributed along the central face of the bidirectional threaded rod 513.
[0026] In addition, the outer wall of the horizontal column 5112 is adapted to the inner side wall of the ventilation plate 5111, and the end face of the horizontal column 5112 is fixedly connected to the side wall of the vertical block 5113.
[0027] Working principle: During long-term operation, the outer wall of the spindle motor 3 generates a large amount of heat, thus requiring cooling. The operator activates the drive motor 518, causing the output shaft 519 to rotate. This rotation of the output shaft 519 carries the air blower blades 5110, facilitating cooling of the spindle motor 3. Subsequently, the operator activates the forward / reverse motor 512, causing the bidirectional threaded rod 513 to rotate. This rotation moves two connecting blocks 514 closer together, causing the rotating block 515 to rotate. The rotation of the rotating block 515 then drives the drive motor 518 to rotate, facilitating uniform airflow into the machine body 1, thus improving the cooling effect on the spindle motor 3 and allowing for cooling of different parts of the spindle motor 3.
[0028] As the rotating block 515 rotates, it causes the displacement block 516 to move. After the displacement block 516 moves, it will cause the extrusion column 517 to extrude. During the movement of the extrusion column 517, it will extrude the ventilation plate 5111, causing the ventilation plate 5111 to slide along the outer wall of the horizontal column 5112 and compress the spring 5114. This makes it easier to extrude the cold air blown out by the blower blade 5110 through the ventilation plate 5111, which facilitates uniform cooling of the main shaft motor 3.
[0029] During the blowing process of the blower blade 5110, the operator starts the coolant storage tank 521, allowing the coolant inside the coolant storage tank 521 to flow into the condenser tube 522, causing cold air to be generated on the outer wall of the condenser tube 522. When the blower blade 5110 blows air, it blows out the cold air, which facilitates the cooling of the spindle motor 3.
[0030] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
