[0002] Machine tool castings refer to various metal castings used in machine tool manufacturing. They mainly include machine tool beds, worktables, columns, crossbeams, gantry top connecting beams, and other components. These castings play a crucial role in the structure of machine tools, affecting not only their stability and durability but also directly related to machining accuracy and efficiency. Machine tool workpiece castings are mainly used for machining work surfaces on machine tools. They have holes and T-slots to fix workpieces and clean up iron filings generated during machining. Machine tool worktables are generally integrally formed during casting and are made of high-strength metal materials. Therefore, a high-strength precision casting is needed for precision machining.

[0003] Existing high-strength precision castings used for precision machining are all integral structures during casting. Although they have high overall strength, they are also heavy and difficult to handle. Moreover, when machining heavy workpieces on the platform, the platform itself also needs to withstand greater pressure. Utility Model Content

Although the overall strength is high, the overall weight is heavy and difficult to handle. Moreover, when machining heavy workpieces on the platform, the platform itself also needs to withstand greater pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength precision casting for precision machining, comprising a casting platform, a cavity formed on one side surface of the casting platform, a honeycomb plate embedded in one end of the cavity, a connecting plate fixedly connected to the lower surface of the casting platform, a first fixing block welded to the side surface of the connecting plate, a first fixing bolt passing through one end of the first fixing block, a base plate provided on one side of the connecting plate, a second fixing block welded to the side surface of the base plate, a threaded tube welded to the inner ring of one end of the second fixing block, a buffer mechanism provided on the inner side of the connecting plate, and mounting mechanisms provided on both sides below the base plate.

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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a high-strength precision casting for precision machining, including a casting platform 1, a cavity 2 is opened on one side surface of the casting platform 1, a honeycomb plate 3 is embedded in one end of the cavity 2, a connecting plate 4 is fixedly connected to the lower surface of the casting platform 1, a first fixing block 5 is welded to the side surface of the connecting plate 4, a first fixing bolt 6 passes through one end of the first fixing block 5, a base plate 7 is provided on one side of the connecting plate 4, a second fixing block 8 is welded to the side surface of the base plate 7, a threaded tube 9 is welded to the inner ring of one end of the second fixing block 8, a buffer mechanism 10 is provided on the inner side of the connecting plate 4, and an installation mechanism 11 is provided on both sides below the base plate 7.

[0021] Furthermore, the honeycomb panel 3 is made of aluminum alloy and is fully welded to the cavity 2. Through the setting of the honeycomb panel 3, the honeycomb structure of the honeycomb panel 3 itself has high strength, which can increase the strength of the casting platform 1 while reducing the weight.

[0022] Furthermore, the positions of the first fixing block 5 and the second fixing block 8 correspond one-to-one. One end of the first fixing bolt 6 passes through the first fixing block 5 and is threadedly connected to the threaded pipe 9. Through the arrangement of the first fixing block 5, the first fixing bolt 6, the base plate 7, the second fixing block 8 and the threaded pipe 9, after the casting platform 1 places the workpiece, the workpiece can be slowly lowered after being buffered by the spring 1003. Then, the first fixing bolt 6 passes through the first fixing block 5 and the threaded pipe 9 to lock the connecting plate 4 and the base plate 7.

[0023] Furthermore, the buffer mechanism 10 includes a first fixing plate 1001, a limiting block 1002, a spring 1003, a second fixing plate 1004, and a limiting tube 1005. The first fixing plate 1001 is welded to one side of the inner wall of the connecting plate 4. The limiting block 1002 is welded to one side of the first fixing plate 1001. The spring 1003 is sleeved around the outer ring of the limiting block 1002. The second fixing plate 1004 is welded to one side of the surface of the base plate 7. The limiting tube 1005 is integrally formed on one side of the second fixing plate 1004. Through the first fixing plate 1001, the limiting block 1002, and the limiting tube 1005, the buffer mechanism... The spring 1003, the second fixing plate 1004, and the limiting tube 1005 are configured such that when a heavy object is placed on the surface of the casting platform 1, the spring 1003 will contract to buffer the pressure and relieve the pressure on the casting platform 1. At the same time, the limiting block 1002 will be embedded in one end of the limiting tube 1005. When the limiting block 1002 and the limiting tube 1005 are in contact, the connecting plate 4 and the base plate 7 will abut against each other. Then, by locking the first fixing bolt 6, the connecting plate 4 and the base plate 7 can be fixed. While completing the pressure buffering, it can also maintain the fixed state after locking.

[0024] Furthermore, one end of the limiting block 1002 is embedded in one end of the limiting tube 1005, and both ends of the spring 1003 are welded to the first fixing plate 1001 and the second fixing plate 1004. Through the setting of the limiting block 1002 and the limiting tube 1005, the cooperation of the limiting block 1002 and the limiting tube 1005 can limit the extension and retraction position of the connecting plate 4, prevent displacement, and form a support structure.

[0025] Furthermore, the mounting mechanism 11 includes a slide rail 1101, a threaded groove 1102, a mounting plate 1103, a connecting groove 1104, a second fixing bolt 1105, and a fixing hole 1106. Slide rails 1101 are fixedly mounted on both sides of the lower surface of the base plate 7. A threaded groove 1102 is formed on one side of the slide rail 1101. A mounting plate 1103 is slidably connected to one end of the slide rail 1101. Connecting grooves 1104 are formed on both sides of the mounting plate 1103. A second fixing bolt 1105 passes through one end of the connecting groove 1104. The mounting plate 1103 has a fixing hole 1106 on its surface, which is provided by the fixing bolt 1105. With the arrangement of the slide rail 1101, threaded groove 1102, mounting plate 1103, connecting groove 1104, second fixing bolt 1105 and fixing hole 1106, the mounting plate 1103 can slide at one end of the slide rail 1101 during use and then be locked by the second fixing bolt 1105. The fixing hole 1106 on the surface of the mounting plate 1103 can be easily connected to the sliding guide rail on the machine tool.

[0026] Furthermore, the threaded grooves 1102 are evenly distributed on the surface of the slide rail 1101, and the second fixing bolt 1105 is threadedly connected to the threaded grooves 1102. The threaded grooves 1102 facilitate the fixing of the mounting plate 1103 in different positions.

[0027] Working principle: First, the honeycomb panel 3 needs to be fully welded into the cavity 2 on one side of the casting platform 1. Then, the mounting plate 1103 is slidably positioned at one end of the slide rail 1101 so that the mounting plate 1103 corresponds to the sliding guide rail of the machine tool. Then, the second fixing bolt 1105 is used to connect the connecting groove 1104 and the threaded groove 1102 to lock the mounting plate 1103. At the same time, the mounting plate 1103 is fixedly connected to the sliding guide rail through the fixing hole 1106. Then, the object to be processed is placed on the surface of the casting platform 1. When the casting platform 1 is under pressure, it will squeeze the spring 1003, so that the limiting block 1002 is embedded in one end of the limiting tube 1005. Next, the first fixing bolt 6 is connected and locked through the first fixing block 5 and the threaded tube 9 to fix the connecting plate 4 and the base plate 7, ensuring that the processed object remains in a stable state.
