Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a spindle cooling system for a vertical machining center. Background Technology

[0002] As the manufacturing industry develops towards higher precision and higher efficiency, the spindle speed of vertical machining centers continues to rise. During operation, the large amount of heat generated by bearing friction, motor operation, and cutting causes thermal deformation of the spindle, resulting in decreased machining accuracy and shortened equipment life. Traditional cooling methods are no longer sufficient to meet the demands. Against this backdrop, the development of an efficient and reliable spindle cooling system has become the key to ensuring machining quality and improving equipment performance, and it is of great significance to promoting the technological upgrading of the machining industry.

[0003] A search revealed Chinese Patent Publication No. CN215035901U, which discloses a spindle cooling system for a vertical machining center. The system includes a spindle housing with a spindle body rotatably connected to its center. Two first slots are fixedly connected to the top of the spindle housing. In this invention, a pump draws high-temperature air from near the spindle body into a U-shaped tube. During cooling with coolant, the air is dispersed by a mesh screen, forming more bubbles and increasing the cooling efficiency. Operators can adjust the area of ​​the first and second through holes by tightening bolts. When the overlap area is small, the airflow is stronger, allowing for rapid cooling of the spindle body. When the overlap area is larger, the cooling airflow is gentler, facilitating continuous cooling of the spindle body. The design structure is flexible and greatly improves the heat dissipation efficiency of the spindle body, while also extending the service life of the spindle body to a certain extent. However, this utility model does not take into account that relying solely on airflow to dissipate heat from the equipment cannot meet the equipment's heat dissipation requirements, and will still lead to an increase in equipment temperature, thereby damaging the internal structure of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vertical machining center spindle cooling system, which aims to improve the problem that the existing technology of relying solely on airflow to dissipate heat from the equipment cannot meet the equipment's heat dissipation requirements and will still cause the equipment temperature to rise, thereby damaging the internal structure of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical machining center spindle cooling system, comprising a support plate, a machining plate fixedly connected to the left side of the top surface of the support plate, a cooling shell fixedly connected to the left side of the top surface of the support plate near the edge, a cooling mechanism provided on the top surface of the support plate for cooling the equipment, and a fixing mechanism provided in the middle of the top surface of the support plate for fixing the workpiece being machined; The cooling mechanism includes a water pipe, the outer wall of which is fixedly connected to the inner wall of the cooling shell. A fan is provided on the left side of the outer wall of the cooling shell. A water pumping assembly is fixedly connected to the front of the top of the cooling shell.

The cooling shell provides necessary cooling protection for the equipment, and the fixing mechanism ensures the stability and accuracy of the processed items during the processing, thereby greatly improving the processing quality and efficiency. The water pipes are connected to the cooling shell to form an efficient cooling circulation path. The fan continuously exhausts hot air, bringing cool air into the equipment. The water pumping unit is responsible for circulating and delivering cooling water to various parts that need cooling. The water filling unit ensures that the water level of the cooling system is always kept at the optimal level.

[0007] As a further description of the above technical solution: The fixing mechanism includes a fixing plate, the bottom of which is fixedly connected to the rear side of the top surface of the support plate, a telescopic rod is fixedly connected to the front side of the fixing plate, a rotating component is provided on the front side of the telescopic rod, and positioning plates are slidably connected to the left and right ends of the front side of the fixing plate.

[0008] The above technical solution ensures the stability of the device by fixing the plate and supporting the plate, allowing the telescopic rod to make precise extension and retraction adjustments within a limited space, and the positioning plate can be precisely positioned according to the needs of the processing plate, thus ensuring the accuracy of the processing.

[0009] As a further description of the above technical solution: The water pumping assembly includes a water tank, the bottom of which is fixedly connected to the top front side of the cooling shell, and a water pump is fixedly connected to the right side of the outer wall of the water tank.

[0010] The above technical solution ensures seamless connection between the two, thereby guaranteeing the overall stability and cooling efficiency of the system. The fixed connection between the water tank and the water pump enables the water circulation system to operate efficiently, providing continuous power support for the entire equipment.

[0011] As a further description of the above technical solution: The water filling assembly includes a water inlet, the bottom of which is connected to the bottom of the water tank, and a plug is provided on the top of the water inlet.

[0012] The above technical solution ensures smooth water replenishment, and the stopper facilitates daily maintenance and inspection.

[0013] As a further description of the above technical solution: The fixing component includes a hollow shell, the right side of which is fixedly connected to the left side of the cooling shell, a ventilation plate is fixedly connected to the right side of the inner wall of the hollow shell, and a motor is fixedly connected to the left side of the ventilation plate.

[0014] Through the above technical solution, the hollow shell not only provides additional structural support for the cooling shell, but also promotes air circulation through its internal ventilation plate. The motor drives the entire cooling system with stable power, ensuring that the equipment can maintain an ideal temperature state even during long-term operation.

[0015] As a further description of the above technical solution: The rotating assembly includes a first rotating ball, the rear side of the outer wall of the first rotating ball is fixedly connected to the front side of the telescopic rod, and rotating rods are rotatably connected to the left and right ends of the front side of the outer wall of the first rotating ball, and a second rotating ball is rotatably connected to the front end of each rotating rod.

[0016] The above technical solution ensures the stability and reliability of both components, and the rotating rod is connected to the rotating ball to form a flexible linkage mechanism.

[0017] As a further description of the above technical solution: The outer wall of the rotating ball is rotatably connected to the outer wall of the positioning plate, and the bottom of the positioning plate is slidably connected to the top of the support plate.

[0018] The above technical solution not only ensures the smoothness of rotation, but also enhances the positioning accuracy of the components.

[0019] As a further description of the above technical solution: The bottom front and rear ends of the processing plate are fixedly connected with inclined plates, and the left side of the cooling shell has multiple heat dissipation holes.

[0020] Through the above technical solutions, the inclined plate not only enhances the structural strength of the processing plate, but also provides additional support for the processing process. The heat dissipation holes fully consider the heat generated by the equipment during long-term operation, ensuring the stability of the equipment and extending its service life.

[0021] This utility model has the following beneficial effects: 1. In this utility model, after the water pump is started, the water pump will draw water from the water tank and flow through the water pipe. The water in the water pipe absorbs the heat of the equipment. At the same time, the motor drives the fan to rotate. The fan draws in cold air and discharges hot air, which enhances the air circulation in the cooling shell and helps to discharge the absorbed heat. This achieves efficient cooling of the equipment, improves the cooling efficiency of the equipment, and extends the service life of the equipment.

[0022] 2. In this utility model, the item needs to be moved to a designated position before processing. The equipment is placed between the rotating components. After sliding into position, the telescopic rod is activated. The telescopic rod causes the first rotating ball to move backward, which in turn drives the rotating rod to rotate around the first and second rotating balls, thereby bringing the positioning plate closer together. This achieves clamping and fixing of the item, preventing it from moving during processing and thus reducing processing accuracy. Attached Figure Description

[0029] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The rotating assembly 303 includes a first rotating ball 3031.

[0030] Working principle: When the equipment needs to be cooled, the water pump 2032 is started. The water pump 2032 will draw water out of the water tank 2031 and flow along the inside of the water pipe 202. The water inside the water pipe 202 can absorb the heat inside the equipment. The motor 2053 is started, and the motor 2053 will drive the fan 201 to rotate. During the rotation of the fan 201, the outside cold air will be drawn in and the hot air inside the cooling shell 5 will be discharged, thereby improving the air circulation inside the cooling shell 5 so that the heat absorbed by the water pipe 202 can be discharged with the air. This achieves efficient cooling of the equipment, improves the cooling efficiency of the equipment, and extends the service life of the equipment. Before processing, the item to be processed needs to be moved to the designated position. Therefore, the device is first placed between the rotating components 303 on both sides and slid inward along the outer wall of the rotating components 303. After reaching the designated position, the telescopic rod 302 is activated. The telescopic rod 302 will pull the rotating ball 3031 to move backward, and the rotating ball 3031 will drive the rotating rods 3032 on both sides to move. This causes one end of the rotating rod 3032 to rotate around the outer wall of the rotating ball 3031, while the other end will rotate around the outer wall of the rotating ball 3033. This pulls the positioning plates 304 on both sides to move inward, thus clamping and fixing the item to prevent it from moving during processing and thus reducing the accuracy of processing.
