[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 3 The bed of a vibration-damping inorganic mineral casting machine tool comprises a bed body 1, a plurality of screws 10, and two guide rails 2. The two guide rails 2 are respectively arranged on opposite sides of the top of the bed body 1. A plurality of mounting grooves 11 are provided on opposite sides of the top of the bed body 1. A plurality of mounting seats 21 are fixedly installed at the bottom of the two guide rails 2. The mounting seats 21 are placed inside the mounting grooves 11 and are fixedly connected by screws 10. A buffer plate 3 is arranged inside the bed body 1. A plurality of fixing grooves 12 are provided on opposite sides of the inside of the bed body 1, and the fixing grooves 12 are located at the top of the buffer plate 3. A vibration-damping component is arranged inside each fixing groove 12. The mounting seat 21 at the bottom of the guide rail 2 is placed into the mounting groove 11 provided on the top of the bed body 1, and then they are fixedly connected together by screws 10, and vibration reduction is performed by the vibration-damping component arranged inside.

[0024] The vibration reduction assembly includes a spring 4 arranged inside the fixed groove 12, the bottom end of the spring 4 is fixedly connected to the top of the buffer plate 3, a fixed ring 41 is fixedly installed on the top of the spring 4, and the outer wall of the fixed ring 41 contacts the inner wall of the fixed groove 12 and is slidably connected thereto, a fixed rod 42 is fixedly installed at the bottom of the guide rail 2, the fixed rod 42 movably penetrates the fixed ring 41 and contacts the top thereof, during the installation process, the fixed rod 42 at the bottom of the mounting seat 21 is inserted into the fixed ring 41 and contacts the top of the fixed ring 41, when the machine tool generates vibration during operation, the vibration energy can be transmitted to the fixed ring 41, and the spring 4 at the bottom is used for buffering, thereby further improving the vibration reduction effect of the bed body 1.

[0025] A clamping block 5 is fixedly installed at the bottom of each mounting seat 21, and a clamping slot 51 is opened inside the bed body 1 and below each mounting slot 11. The clamping block 5 is slidably connected to the clamping slot 51, and the bottom of the clamping block 5 is in contact with the top of the buffer plate 3. Since the clamping block 5 and the clamping slot 51 are both cross-shaped, the stability of the guide rail 2 is improved.

[0026] A vibration-damping gasket 6 is arranged between the mounting groove 11 and the mounting seat 21. The screw 10 and the block 5 are movable through the vibration-damping gasket 6. The vibration-damping gasket 6 can improve the stability and durability of the connection between the mounting seat 21 and the bed body 1. At the same time, the vibration-damping gasket 6 has a certain vibration-damping and vibration-absorbing effect, further improving the vibration-damping effect of the bed body 1.

[0027] The inner wall of each slot 51 is provided with a rubber sheet 7 , and the inner wall of the rubber sheet 7 contacts the outer wall of the block 5 . The energy generated by vibration is absorbed by the rubber sheet 7 , thereby further improving the vibration reduction effect of the bed body 1 .

[0028] The entire bed body 1 is made of vibration-damping material, and the vibration-damping material is one of cast iron, steel, and concrete. Since the above materials can effectively reduce the generation and propagation of vibration, corresponding selection can be made according to actual needs to improve the limitations of the equipment.

[0029] The shape of the fixing groove 12 is narrow at the top and wide at the bottom, and the shape of the fixing rod 42 is wide at the top and narrow at the bottom. Since the fixing groove 12 is designed to be narrow at the top and wide at the bottom, the fixing ring 41 can be limited to prevent the fixing ring 41 from being affected by the elastic force of the spring 4 and detaching from the fixing groove 12. Since the fixing groove 12 is designed to be wide at the top and narrow at the bottom, the narrow part of the fixing ring 41 can pass through the fixing ring 41, and the wider side can contact the top of the fixing ring 41.

[0030] The operating principle of this embodiment is as follows: when in use, the staff first puts the vibration-damping gasket 6 into each mounting groove 11, and then puts the mounting seat 21 at the bottom of the guide rail 2 into the mounting groove 11 opened at the top of the bed body 1, and fixes it with screws 10. At the same time, the fixing rod 42 at the bottom of the mounting seat 21 adopts a design that is wide at the top and narrow at the bottom, so that it can pass through the fixing ring 41 and its top is in contact. When the machine tool vibrates during operation, it can contact the fixing ring 41 through the fixing rod 42, and can transfer the vibration energy to the fixing ring 41. It can also use the spring 4 at the bottom, the fixing ring 41 and the fixing rod 42, and the friction resistance between the fixing ring 41 and the fixing groove 12 to buffer, further improve the vibration reduction effect of the guide rail 2, prevent the screws 10 from loosening, and thus ensure the stability of the connection between the bed body 1 and the guide rail 2.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
