Description

Technical Field

[0001] The utility model specifically relates to the technical field of spindle box cooling, and specifically is a mineral casting spindle box with a cooling structure. Background Technique

[0002] The ore casting spindle box is a mechanical component with unique properties and application values; the ore casting is a new type of material with excellent damping characteristics, high-precision retention, and good thermal stability. When used to manufacture the spindle box, it brings many advantages; due to its excellent damping characteristics, it can effectively reduce the vibration generated during the operation of the machine tool, thereby improving the machining accuracy and surface quality.

[0003] Currently, traditional spindle boxes are made of cast iron. Although the spindle box supported by cast iron has good sealing performance, the heat dissipation effect of the traditional spindle box is not ideal. In such a long-term use, the temperature inside the spindle box is relatively high, which will affect the temperature of the surface of the rotating shaft. This will cause the lubricating oil inside the spindle box to be consumed rapidly. When the lubricating oil cannot be added in time, the friction between the rotating shaft and the bearing bush on the spindle box will increase, resulting in a significant reduction in the lifespan of the rotating shaft.

[0004] After retrieval, Chinese Patent Publication No. CN202320744488.3 discloses a high-precision spindle box cooling structure using external circulating cooling water; it includes a spindle seat, a cooling water tank is installed on the top of the spindle seat, and a cooling water inlet pipe and an outlet pipe for cooling water to enter and exit are respectively arranged on the side surface of the cooling water tank; a cover, the cover is installed on the top of the cooling water tank for sealing the tank opening of the cooling water tank, and a partition for separating the internal space of the cooling water tank is vertically arranged on the bottom surface of the cover;

[0005] The cooling water tank in the above patent is installed on the top of the spindle seat, and an inlet pipe and an outlet pipe are arranged on both sides of the cooling water tank. The high temperature generated inside the spindle seat is dissipated by water. In this way, a large amount of water resources are required, and the inlet pipe and the outlet pipe in the above patent are installed at a position close to the top of the cooling water tank. When water cooling is carried out, there will always be residual water in the cooling water tank. When new water enters, it will first mix with the water with temperature and then transfer the temperature generated inside the spindle box. In this way, the conversion effect of water on temperature is reduced, and the maximum cooling effect of water cannot be effectively exerted. Therefore, the structure in the above patent still has certain technical defects;

[0006] In view of the above situation, we provide a mineral casting spindle box with a cooling structure. In this device, the spindle box is made of mineral casting. Through the thermal stability of the mineral casting spindle box itself, it is possible to effectively protect the rotating shaft and gears inside the spindle box to a certain extent. This can effectively increase the working time of the rotating shaft and gears and improve work efficiency. When the thermal stability of the spindle box itself cannot continue to digest the temperature generated inside the spindle box, it is effectively transferred through the heat sinks provided on the outer wall, transferring the temperature inside the spindle box to the outside of the spindle box. Then, the heat sink installed at the center of the mounting frame on the heat sink dissipates the transferred temperature to control the temperature inside the spindle box and ensure the working efficiency of the rotating shaft and gears inside the spindle box. Summary of the Invention
