Description
Technical Field
[0001] This utility model relates to the field of support structures, specifically to a vibration damping support structure for a mineral casting machine tool column. Background Technology
[0002] The machine tool column is the core structural component of the machine tool, mainly responsible for support and guidance, and directly affects the machining accuracy and equipment stability. Mineral castings are a new type of non-metallic composite material made from mineral materials as the main raw material through a specific process. They have the characteristics of being environmentally friendly and having excellent performance. As a new type of material that combines performance and environmental protection advantages, mineral castings can be used in high-precision equipment such as machine tool beds, machining center bases, and coordinate measuring machines, relying on their high dimensional stability and vibration reduction properties to improve machining accuracy.
[0003] A Chinese patent authorization announcement (CN209551119U) discloses a shock-absorbing machine tool column, comprising a column body, connectors, support components, support plates, shock-absorbing devices, and a protective layer. The shock-absorbing devices are installed at both ends of the bottom surface of the support plate. Force is applied through a first fixed plate, and a sliding rod at the bottom of the top plate slides up and down on a sliding rod on the bottom plate via a spring. This allows the first fixed plate to absorb shock through the shock-absorbing devices on the second fixed plate, enhancing the stability of the machine tool column and improving working efficiency. A protective layer is installed at the bottom surface of the shock-absorbing device. Aramid fibers provide impact resistance and wear resistance, offering strong protection. A double-layer cushioning effect using TPU foam and PC rubber further enhances the shock absorption, providing effective shock protection for the column and making it convenient to use.
[0004] The above-mentioned shock absorption structure also has the following problems when in use: the springs in the above-mentioned shock absorption structure weaken after a long period of use and need to be replaced. The replacement of the springs in the above-mentioned structure is relatively inconvenient, which in turn affects the use of the shock absorption structure.
[0005] Therefore, it is necessary to invent a vibration damping support structure for the column of a mineral casting machine tool to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a vibration damping support structure for a mineral casting machine tool column, in order to solve the problem mentioned in the background art where the springs in the aforementioned vibration damping structures weaken due to prolonged use and need to be replaced. The replacement of springs in the aforementioned structures is inconvenient, which in turn affects the use of the vibration damping structure.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping support structure for a mineral casting machine tool column, comprising a column body, a pad 1 fixedly installed at the lower end of the column body, and a pad 2 installed at intervals at the lower end of the pad 1. Upper threaded blocks and lower threaded blocks are respectively threaded into the threaded grooves reserved inside the pad 1 and pad 2, and a damping rod is fixedly installed between the upper threaded blocks and the lower threaded blocks. A spring 1 is fixedly installed between the upper threaded blocks and the lower threaded blocks, wherein the spring 1 is movably fitted onto the outer ring of the damping rod. A hexagonal groove is opened inside the upper threaded block, and the hexagonal groove matches the specifications of a hexagonal wrench. A shielding component is movably installed in the hexagonal groove for dust prevention.
[0008] Preferably, the outer threads of the upper and lower threaded blocks have different directions, while the overall heights of the upper and lower threaded blocks are equal. The upper threaded block is threadedly connected to the threaded groove reserved inside the first pad, and the lower threaded block is threadedly connected to the threaded groove reserved inside the second pad. This ensures that rotating the upper threaded block synchronously moves the lower threaded block. The different directions of the outer threads of the upper and lower threaded blocks cause relative movement when they rotate, facilitating the synchronous disengagement of the upper and lower threaded blocks from the threaded grooves inside the first and second pads, thereby enabling the disassembly of the upper and lower threaded blocks from the first and second pads.
[0009] Preferably, the shielding component includes a hexagonal plate that is slidably connected to the hexagonal groove, and the side wall of the hexagonal plate is attached to the inner wall of the hexagonal groove to achieve a sliding connection between the upper and lower parts. The top of the hexagonal plate is flush with the top wall of the upper threaded block, so that dust and impurities will not fall into the hexagonal groove and affect the subsequent matching of the wrench with the hexagonal groove.
[0010] Preferably, the shielding assembly further includes a vertical rod fixedly connected to the hexagonal plate, and the vertical rod and the movable groove reserved inside the upper threaded block are elastically connected by a spring. The elastic force applied by the spring causes the hexagonal plate to be lifted up and flush with the top wall of the upper threaded block.
[0011] Preferably, the shielding component further includes a block fixedly installed at the lower end of the upright, and the two blocks are arranged in a group, symmetrically arranged with the central axis of the upright as the left and right sides. The blocks and the upright are slidably connected to the movable groove reserved inside the upper threaded block to ensure the stability of the hexagonal plate moving up and down.
[0012] Preferably, the movable groove is composed of a columnar groove and a strip groove connected to the columnar groove, and the inner wall of the columnar groove is attached to the outer wall of the upright to achieve a sliding connection, and the inner wall of the strip groove is attached to the outer wall of the block to achieve a sliding connection.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a wrench that matches a hexagonal groove. Turning the wrench causes the upper threaded block to rotate, and the rotation of the upper threaded block synchronously causes the lower threaded block to rotate. The different threads on the outer rings of the upper and lower threaded blocks cause relative movement when they rotate, which facilitates the upper and lower threaded blocks to simultaneously leave the threaded grooves inside the first and second pads, thereby enabling the disassembly and replacement of the upper and lower threaded blocks with the first and second pads, and facilitating the replacement and maintenance of the first spring and the damping rod. 2. At the same time, under the force applied by the second spring, the top of the hexagonal plate is flush with the top wall of the upper threaded block, so that dust and impurities will not fall into the hexagonal groove and affect the subsequent matching of the wrench and the hexagonal groove.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model provides, for example Figure 1-4The diagram illustrates a vibration damping support structure for a mineral casting machine tool column. It includes a column body 3, with a pad 1 fixedly installed at the lower end of the column body 3. Pads 2 are spaced apart at the lower end of pad 1. Upper threaded blocks 4 and lower threaded blocks 5 are threadedly connected to pre-drilled grooves 6 inside pad 1 and pad 2, respectively. A damping rod 7 is fixedly installed between the upper threaded blocks 4 and lower threaded blocks 5. The upper and lower ends of the damping rod 7 are respectively welded to the bottom wall of the upper threaded block 4 and the top wall of the lower threaded block 5, thus enabling the upper threaded blocks 4 and lower threaded blocks 5 to effectively... The upper threaded block 4 and the lower threaded block 5 are now rotating synchronously, and a spring 8 is fixedly installed between them. The spring 8 is movably fitted on the outer ring of the damping rod 7. The upper and lower ends of the spring 8 are fixedly welded to the bottom wall of the upper threaded block 4 and the top wall of the lower threaded block 5, respectively. The spring 8 does not contact the outer wall of the damping rod 7. The upper threaded block 4 has a hexagonal groove 9 inside, and the hexagonal groove 9 matches the specifications of a hexagonal wrench. A shielding component 10 is movably installed in the hexagonal groove 9 for dust prevention. The spring 8 and the damping rod 7 work together to achieve the buffering and shock absorption function of the column body 3.
[0019] Using a wrench that matches the hexagonal slot 9, turning the wrench rotates the upper threaded block 4. The rotation of the upper threaded block 4 synchronously rotates the lower threaded block 5. The different threads on the outer rings of the upper and lower threaded blocks 4 and 5 cause relative movement when they rotate, facilitating the simultaneous disengagement of the upper and lower threaded blocks 4 and 5 from the threaded slots 6 inside the pad 1 and pad 2. This allows for the disassembly and replacement of the upper and lower threaded blocks 4 and 5 from the pad 1 and pad 2, and facilitates the replacement and maintenance of the spring 8 and damping rod 7. Subsequently, the force on the column body 3 is transmitted to the pad 1. At this time, the hydraulic oil inside the damping rod 7 flows in the piston through hole, generating resistance and achieving shock absorption support for the column body 3, ensuring the stability of the column body 3 during use.
[0020] To ensure that the upper threaded block 4 and the lower threaded block 5 can be separated from the first pad 1 and the second pad 2 simultaneously, the outer threads of the upper threaded block 4 and the lower threaded block 5 are designed with different directions. The overall height of the upper threaded block 4 and the lower threaded block 5 is equal. The upper threaded block 4 is threadedly connected to the threaded groove 6 reserved inside the first pad 1, and the lower threaded block 5 is threadedly connected to the threaded groove 6 reserved inside the second pad 2. This ensures that rotating the upper threaded block 4 will synchronously adjust the rotation of the lower threaded block 5. The different directions of the outer threads of the upper threaded block 4 and the lower threaded block 5 cause relative movement when they rotate, which facilitates the upper threaded block 4 and the lower threaded block 5 to leave the threaded groove 6 inside the first pad 1 and the second pad 2 simultaneously, thereby realizing the disassembly of the upper threaded block 4 and the lower threaded block 5 from the first pad 1 and the second pad 2.
[0021] The shielding assembly 10 includes a hexagonal plate 101 that is slidably connected to the hexagonal groove 9, and the sidewall of the hexagonal plate 101 is attached to the inner wall of the hexagonal groove 9 to achieve a vertical sliding connection.
[0022] The shielding assembly 10 also includes a vertical rod 102 fixedly connected to the hexagonal plate 101. The vertical rod 102 and the movable groove 104 reserved inside the upper threaded block 4 are elastically connected by a second spring 105. The elastic force applied by the second spring 105 causes the hexagonal plate 101 to be lifted up and flush with the top wall of the upper threaded block 4. The shielding assembly 10 also includes a square block 103 fixedly installed at the lower end of the vertical rod 102. The two square blocks 103 are arranged in a group and are symmetrically arranged on the left and right sides with the central axis of the vertical rod 102 as the axis of symmetry. The square blocks 103 and the vertical rod 102 are slidably connected to the movable groove 104 reserved inside the upper threaded block 4 to ensure the stability of the hexagonal plate 101 moving up and down.
[0023] The movable groove 104 is composed of a columnar groove and a strip groove connected to the columnar groove. The inner wall of the columnar groove is attached to the outer wall of the upright 102 to achieve a sliding connection, and the inner wall of the strip groove is attached to the outer wall of the block 103 to achieve a sliding connection.
[0024] The top of the hexagonal plate 101 is flush with the top wall of the upper threaded block 4, so that dust and impurities will not fall into the hexagonal groove 9 and affect the subsequent matching of the wrench with the hexagonal groove 9. Subsequently, by applying external force to the hexagonal wrench to apply a downward force to the hexagonal plate 101, the hexagonal plate 101 will be lowered to expose the hexagonal groove 9, and the hexagonal wrench can then match with the hexagonal groove 9 to realize the rotation of the upper threaded block 4.
[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
