Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a shockproof base for numerical control machine tools. Background Art
[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It logically processes programs defined by control codes or other symbolic instructions, decodes them, and inputs them into the CNC device via an information carrier. Through computational processing, the CNC device issues various control signals, controlling the machine's movements and automatically producing parts to the shape and dimensions specified in the drawings. A CNC machine tool's anti-vibration mount is an auxiliary device specifically designed to reduce vibrations generated during machine operation. If left uncontrolled, these vibrations can affect the machine's machining accuracy and stability, shorten its service life, and potentially reduce the quality of the finished parts.
[0003] Traditional anti-vibration bases for CNC machine tools consist of a base plate, support components, shock-absorbing springs and other parts. When the machine tool vibrates during processing, the shock-absorbing springs can absorb the vibration energy and consume the energy through deformation or fluid flow, thereby reducing the impact of vibration on the machine tool itself and the workpiece.
[0004] Traditional anti-vibration bases for CNC machine tools have a simple structure and only use springs for shock absorption. Long-term compression of the springs will cause the springs to deform, resulting in poor shock absorption effect. Therefore, a anti-vibration base for CNC machine tools is proposed to solve the above problems. Utility Model Content

Through the above structure, the machine tool can be moved without removing the bottom plate, thereby improving the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1 、 Figure 2 and Figure 5 , the utility model provides an embodiment: a shock-proof base for a CNC machine tool, including a fixed base 1, a base 2 is slidably connected inside the fixed base 1, a bottom plate 3 is fixedly connected to the lower surface of the fixed base 1, a support leg 4 is fixedly connected to the lower surface of the bottom plate 3, a shock-absorbing mechanism is provided inside the fixed base 1, a moving component is provided inside the bottom plate 3, one end of a fixed rod 7 is fixedly connected to the side wall of the mounting sleeve 2 12, one end of a first spring 8 is fixedly connected to the side wall of the mounting sleeve 1 6, the other end of the first spring 8 is fixedly connected to the side wall of the slider 9, the side wall of the fixed block 11 is fixedly connected to the lower surface of the base 2, one end of a connecting column 13 is fixedly connected to the lower surface of the base 2, the shock-absorbing mechanism includes a damper 5, one end of the damper 5 is fixedly connected to the inside of the fixed base 1, The other end of the diaphragm 5 is fixedly connected to the lower surface of the base 2, and the interior of the fixed base 1 is fixedly connected to a mounting sleeve 6, and the interior of the mounting sleeve 6 is fixedly connected to a mounting sleeve 2 12, and the interior of the mounting sleeve 2 12 is slidably connected to a connecting column 13, and the side wall of the connecting column 13 is fixedly connected to a fixing ring 14, and a second spring 15 is provided inside the mounting sleeve 2 12, and one end of the second spring 15 is fixedly connected to the side wall of the fixing ring 14, and the other end of the second spring 15 is fixedly connected to the interior of the mounting sleeve 2 12, and the interior of the side wall of the mounting sleeve 6 is fixedly connected to a fixing rod 7, and the side wall of the fixing rod 7 is slidably connected to a slider 9, and the side wall of the fixing rod 7 is sleeved with a first spring 8, and the side wall of the slider 9 is rotatably connected to a rotating bar 10, and one side of the rotating bar 10 is rotatably connected to a fixed block 11;
[0035] When using the equipment, the machine tool needs to be installed on the base 2 first to complete the connection operation between the two. When the machine tool starts to perform processing work, the vibration generated by the operation of the machine tool will inevitably be transmitted to the base 2. The transmission of this vibration will cause the base 2 to exert a certain pressure on the fixed block 11. Under such pressure, the rotating bar 10 will start to rotate. The rotation of the rotating bar 10 will push the slider 9 to slide on the fixed rod 7. As the slider 9 slides, it will generate an extrusion force on the first spring 8, causing the first spring 8 to contract. At the same time, the connecting column 13 will also be subjected to an extrusion force. Under this extrusion, the connecting column 13 will push the fixed ring 14 to slide downward. The downward movement of the fixing ring 14 will squeeze the second spring 15, thereby causing the second spring 15 to contract. Finally, the vibration force generated during the whole process will be effectively absorbed by the damper 5. Through such a series of structural designs and interactions, an ideal shock absorption effect can be achieved to ensure the stability of the equipment during operation. This structure can effectively absorb and isolate the vibrations generated during the operation of the machine tool, reduce the transmission of these vibrations to the machine tool itself and the processed parts, and thus improve the processing accuracy and surface quality.
[0036] Reference Figure 3 and Figure 4 The moving assembly includes a fixed column 16, the lower surface of the fixed column 16 is fixedly connected to the inside of the bottom plate 3, the upper surface of the fixed column 16 is fixedly connected to the top plate 17, a connecting plate 25 is provided at the bottom of the bottom plate 3, the lower surface of the connecting plate 25 is fixedly connected to the pulley 26, the top plate 17 is rotatably connected to the inside of the sprocket 18, a chain 19 is provided between the sprockets 18, a tensioner 27 is fixedly connected to the upper surface of the bottom plate 3, the side wall of the tensioner 27 is in contact with the side wall of the chain 19, and the upper surface of the top plate 17 on one side is fixed. A side plate 20 is fixedly connected, a motor 21 is fixedly connected to the lower surface of the side plate 20, the output end of the motor 21 is fixedly connected to the inside of the sprocket 18, a screw 22 is fixedly connected to the lower surface of the sprocket 18, the side wall of the screw 22 is rotatably connected to the inside of the top plate 17, the side wall of the screw 22 is threadedly connected to the fixed plate 23, the lower surface of the fixed plate 23 is fixedly connected to the fixing column 24, the lower surface of the fixing column 24 is fixedly connected to the upper surface of the connecting plate 25, and the side wall of the fixing column 24 is slidably connected to the inside of the bottom plate 3.
[0037] When the machine tool needs to be moved, the motor 21 is started first. Once the motor 21 is started, the sprocket 18 will start to rotate. Due to the connection between the sprocket 18 and the chain 19, the rotation of the sprocket 18 will drive the chain 19 to rotate synchronously. In the process of rotation, the chain 19 will in turn prompt the other sprockets 18 connected thereto to start rotating. The rotation of the sprocket 18 further drives the screw 22 to start rotating. After the screw 22 rotates, it will drive the fixed column 24 to slide down in a certain direction. During the sliding process of the fixed column 24, it will push the connecting plate 25 connected thereto to move downward. As the connecting plate 25 moves downward, the fixed column 24 will move downward. By moving, the pulley 26 can be gradually lifted up. When the pulley 26 is lifted up to a certain height, the supporting leg 4 will be off the ground. In this case, the entire equipment can be pushed to move, thereby achieving the effect of moving the machine tool. A tensioner 27 is installed on the side of the chain 19. The tightness of the chain 19 can be adjusted by the tensioner 27. This structure that is easy to move the machine tool can quickly adjust the position of the machine tool, shorten the preparation time, speed up the production process, and thus improve the overall work efficiency. When not in use, the machine tool can be moved to a warehouse or a place that does not occupy the work area, which helps to optimize the utilization of the workshop space.
[0038] Working principle: When the equipment is used for work, the connection is completed by installing the machine tool on the base 2. During the processing of the machine tool, the vibration generated by it will be transmitted to the base 2, causing the base 2 to press the fixed block 11, thereby allowing the rotating bar 10 to rotate, pushing the slider 9 to slide on the fixed rod 7, and then squeezing the first spring 8 to make it contract. At the same time, the connecting column 13 will be squeezed and push the fixed ring 14 to slide down, causing it to squeeze and contract the second spring 15. Finally, the vibration force generated will be absorbed by the damper 5, thereby achieving a shock absorption effect. When the machine tool needs to be moved, the motor 21 is started to drive the sprocket 18 to rotate, driving the chain 19 to rotate. The rotation of the chain 19 causes the sprocket 18 to rotate synchronously, and then drives the screw 22 to rotate, causing it to drive the fixed column 24 to slide down, pushing the connecting plate 25 down, thereby lifting the pulley 26 and making the support leg 4 leave the ground. At this time, the equipment can be pushed to move, thereby achieving the effect of moving the machine tool.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
