Description

Technical Field

[0001] The present application relates to the technical field of shock absorbing devices, and in particular to a shock absorbing device and a shock absorbing method thereof for titanium alloy processing machine tools. Background Art

[0002] ‌‌Titanium alloy is an important structural metal with high strength, good corrosion resistance and heat resistance. Titanium alloy processing requires the use of special titanium alloy processing machine tools, but due to the high strength of titanium alloy, high-frequency vibration will be generated during titanium alloy processing. Working in a vibration environment will seriously affect the service life of the equipment.

[0003] At present, machine pads are often installed on the bottom of titanium alloy processing machine tools for shock absorption. However, since the machine pads need to be fixed to the bottom of the titanium alloy processing machine tools by bolts, and titanium alloy processing machine tools are often not equipped with corresponding screw holes when leaving the factory, it is easy to be difficult to install. In addition, there are various types of titanium alloy processing machine tools, and different types of titanium alloy processing machine tools have different bottom shapes, so it is difficult to meet this requirement by installing ordinary machine pads. Summary of the invention

[0004] In order to facilitate the provision of shock absorption for different types of titanium alloy processing machine tools, the present application provides a shock absorption device and a shock absorption method for a titanium alloy processing machine tool.

[0005] In the first aspect, the present application provides a shock absorbing device for a titanium alloy processing machine tool, which adopts the following technical solution: A shock absorbing device for a titanium alloy processing machine tool comprises a shock absorbing base installed at the bottom of the machine tool body, the shock absorbing base comprises at least four supporting sub-bases, telescopic rods are respectively hingedly arranged between adjacent supporting sub-bases, and first shock absorbing members are respectively arranged on the bottom surfaces of at least four supporting sub-bases.

[0006] By adopting the above technical solution, at least four support sub-bases are interconnected by telescopic rods to prevent the support sub-bases from shifting when the machine tool body is vibrating and supporting the machine tool body. When the shock-absorbing base needs to be installed at the bottom of the machine tool body, the four support points at the bottom are determined according to the overall situation of the machine tool body, and then the support sub-bases are placed at the four support points. During this process, the four support sub-bases remain interconnected by telescopic rods to adapt to different models of titanium alloy processing machine tools. When the machine tool body vibrates, the vibration force of the machine tool body is weakened by the first shock-absorbing component.

[0007] Optionally, a limiting member is provided for the lifting of the side wall of the support sub-base, a lifting guide block is provided on the outer wall of the support sub-base, a lifting guide groove is opened on the inner wall of the limiting member corresponding to the position of the lifting guide block, the lifting guide block is slidably connected to the lifting guide groove, and the support sub-base is provided with a lifting mechanism for driving the limiting member to lift and lower.

[0008] By adopting the above technical solution, under the guiding action of the lifting guide block, the limit member is driven to rise through the lifting mechanism. At this time, the limit member limits the edge of the machine tool body. When the machine tool body starts and vibrates, the limit member contacts the edge of the machine tool body to prevent the support sub-seat from shifting due to vibration.

[0009] Optionally, the lifting mechanism includes a first connecting rod, a side wall of the support sub-base is provided with a transverse groove, the first connecting rod is slidably arranged in the transverse groove, one end of the first connecting rod extends outside the side wall of the support sub-base, one end of the first connecting rod is provided with a first wedge surface, the bottom surface of the limiting member is provided with a lifting wedge surface, the first wedge surface cooperates with the lifting wedge surface, and the support sub-base is provided with a moving component for controlling the sliding of the first connecting rod.

[0010] By adopting the above technical solution, when it is necessary to drive the limit member to rise, the first connecting rod is driven to slide in the direction close to the limit member through the moving component. Since the first wedge surface and the lifting wedge surface cooperate with each other, the first connecting rod drives the limit member to rise, which is beneficial to improve the stability of the lifting and lowering of the limit member.

[0012] By adopting the above technical solution, when the machine tool body is installed on the supporting sub-base, the machine tool body drives the second connecting rod to descend through its own gravity. Since the first connecting rod and the second connecting rod cooperate through the second wedge surface, the descending second connecting rod drives the first connecting rod to move in the direction close to the limit member, and the first connecting rod finally drives the limit member to rise, which is beneficial to improve the stability of the limit member limiting the machine tool body.

[0013] Optionally, a support adjustment plate is swingably provided on the top surface of the telescopic rod, the top surface of the support adjustment plate is flush with the top surface of the support sub-base, the bottom surface of the support adjustment plate is detachably provided with a second shock absorber, and the support adjustment plate is provided with a disassembly and assembly mechanism for assembling the second shock absorber.

[0014] By adopting the above technical solution, when it is necessary to increase the support shock-absorbing point, the support adjustment plate is driven to swing in the direction away from the telescopic rod, and then the second shock-absorbing component is installed on the bottom surface of the support adjustment plate through the disassembly and assembly mechanism. At this time, the second shock-absorbing component assists in supporting and shock-absorbing the machine tool body, which is beneficial to increase the shock-absorbing effect of the machine tool body.

[0015] Optionally, the disassembly and assembly mechanism includes a hemispherical block, a sliding groove is provided on the top surface of the second shock absorber, the hemispherical block is slidably connected to the sliding groove, a first spring is provided in the sliding groove, one end of the first spring is connected to the bottom wall of the sliding groove, and the other end of the first spring is connected to the bottom surface of the hemispherical block, a slot is provided on the bottom surface of the support adjustment plate, the hemispherical block is plugged into the slot, and the support adjustment plate is provided with a fixing component for fixing the hemispherical block in the slot.

[0016] By adopting the above technical solution, after the support adjustment plate swings, when the second shock absorber needs to be installed, the second shock absorber is extended between the support adjustment plate and the ground, and the support adjustment plate squeezes the hemispherical block, and the hemispherical block squeezes the first spring, and when the hemispherical block is aligned with the slot, the first spring releases the elastic force and drives the hemispherical block to be inserted into the slot, and the hemispherical block is fixed in the slot under the action of the fixing assembly, and the second shock absorber is fixed to the bottom surface of the support adjustment plate, which is beneficial to improve the convenience of assembling the second shock absorber.

[0018] By adopting the above technical solution, when the hemispherical block is inserted into the locking groove, the hemispherical block squeezes the insertion rod through the third wedge surface, and the insertion rod then squeezes the second spring. When the insertion rod is aligned with the locking groove, the second spring releases the elastic force and drives the insertion rod to be inserted into the locking groove. At this time, the hemispherical block is fixed in the locking groove. Similarly, when the hemispherical block needs to be removed, the insertion rod is driven to move in a direction away from the hemispherical block, thereby releasing the lock on the hemispherical block, which is conducive to improving the convenience of disassembly and assembly of the second shock absorber.

[0019] Optionally, a convex point is provided on the bottom surface of the support adjustment plate, a groove is provided on the top surface of the telescopic rod, and the convex point is engaged with the groove.

[0020] By adopting the above technical solution, when the support adjustment plate is attached to the top surface of the telescopic rod, the protrusion is engaged in the groove, which helps to prevent the support adjustment plate from swinging randomly when it is not in use and the machine tool body vibrates.

[0021] In a second aspect, the present application provides a shock absorbing method for a titanium alloy processing machine tool, which comprises the following steps: S1: Lift the machine tool body, determine at least four supporting points according to the bottom shape of the machine tool body, and then place at least four supporting sub-bases at the positions of the at least four supporting points respectively; S2: Lower the machine tool body and drive the limiter to rise through the lifting mechanism to prevent the shock-absorbing base from shifting; S3: according to the actual vibration of the machine tool body during operation, add a support point. At this time, first swing the support adjustment plate to the support point position, and then install the second shock absorbing member through the disassembly and assembly mechanism; S4: Start the machine tool body, and reduce the vibration of the machine tool body to the ground through the first shock absorbing member and the second shock absorbing member.

[0022] By adopting the above technical solution, the first shock absorber is placed at the support point according to the bottom shape of the machine tool body, and the second shock absorber is used to increase the shock absorption of the machine tool body, which is beneficial to improve the convenience of providing shock absorption for different models of titanium alloy processing machine tools.

During this process, the four support sub-bases remain interconnected by telescopic rods to adapt to different models of titanium alloy processing machine tools. When the machine tool body vibrates, the vibration force of the machine tool body is weakened by the first shock-absorbing component. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] First, see Figure 1 and Figure 2 A shock absorbing device for a titanium alloy processing machine tool comprises a shock absorbing base 2 installed at the bottom of a machine tool body 1. The shock absorbing base 2 comprises a supporting sub-base 3, and the number of the supporting sub-bases 3 is at least four. In this embodiment, the number of the supporting sub-bases 3 is four. A telescopic rod 4 is hingedly installed between two adjacent supporting sub-bases 3, and the four supporting sub-bases 3 are enclosed by the telescopic rods 4 to form a frame shape. The bottom surfaces of the four supporting sub-bases 3 are respectively fixedly connected with first shock absorbing members 5.

[0028] When a shock absorbing device is required to be installed at the bottom of the machine tool body 1, the machine tool body 1 is first lifted, and then the four supporting shock absorbing points of the machine tool body 1 are determined. Then the four supporting sub-bases 3 are respectively placed opposite to the positions of the four supporting shock absorbing points, and at this time the four supporting sub-bases 3 are connected to each other through the telescopic rod 4. Finally, the machine tool body 1 is placed on the four supporting sub-bases 3. When the machine tool body 1 is started and vibrates, the vibration force is first transmitted to the four supporting sub-bases 3. The four supporting sub-bases 3 then transmit the vibration force to the first shock absorbing component 5, and at this time the first shock absorbing component 5 weakens the vibration force. In the above process, under the connecting action of the telescopic rod 4, the displacement of the supporting sub-base 3 due to vibration is avoided. At the same time, by arbitrarily adjusting the position of the supporting sub-base 3, it can adapt to machine tool bodies 1 of different models.

[0029] See also Figure 2 and Figure 3 In order to further prevent the support sub-base 3 from shifting under the influence of vibration when the machine tool body 1 is started, a limiter 6 is installed on the outer wall of the support sub-base 3. The limiter 6 is L-shaped, and the L-shaped limiter 6 is conducive to covering the edges and corners of the machine tool body 1. A lifting guide block 7 is fixedly connected to the outer wall of the support sub-base 3, and a lifting guide groove 8 is opened on the inner side of the limiter 6 along the vertical direction of the limiter 6, and the lifting guide block 7 is slidably connected to the lifting guide groove 8.

[0030] See also Figure 3 In order to facilitate the lifting and moving of the limiter 6, the support sub-base 3 is equipped with a lifting mechanism, which includes a first connecting rod 9. The side wall of the support sub-base 3 is provided with a transverse groove 10, and the first connecting rod 9 is slidably installed in the transverse groove 10. One end of the first connecting rod 9 extends outside the side wall of the support sub-base 3, and one end of the first connecting rod 9 is provided with a first wedge surface 11. The bottom surface of the limiter 6 is provided with a lifting wedge surface 12, and the first wedge surface 11 and the lifting wedge surface 12 cooperate with each other.

[0031] See also Figure 3 In order to facilitate the lifting of the limiter 6 to limit the position of the machine tool body 1 when the machine tool body 1 is installed on the support sub-base 3, a moving assembly is also installed on the support sub-base 3. The moving assembly includes a second connecting rod 13, and a vertical groove 14 is provided on the top surface of the support sub-base 3, and the vertical groove 14 is connected to the horizontal groove 10. The second connecting rod 13 is slidably arranged in the vertical groove 14, and the top end of the second connecting rod 13 extends outside the top of the support sub-base 3. The end of the first connecting rod 9 close to the second connecting rod 13 is provided with a second wedge surface 15, and the first connecting rod 9 and the second connecting rod 13 cooperate with each other through the second wedge surface 15.

[0032] When the machine tool body 1 is placed on the supporting sub-base 3, the machine tool body 1 presses down the second connecting rod 13 by its own gravity, and the second connecting rod 13 drives the first connecting rod 9 to move toward the direction close to the limiting member 6 through the second wedge surface 15. The first connecting rod 9 drives the limiting member 6 to rise through the cooperation of the first wedge surface 11 and the lifting wedge surface 12. At this time, the L-shaped limiting member 6 limits the corners of the machine tool body 1. The limiting member 6 cooperates with the telescopic rod 4 to prevent the first shockproof member from shifting when the machine tool body 1 vibrates.

[0033] It should be noted that the gravity of the limiter 6 is greater than the second connecting rod 13. By setting the limiter 6 by lifting, it is beneficial to lift the machine tool body 1 to a lower height when the shock-absorbing base 2 needs to be disassembled, and then the shock-absorbing base 2 can be taken out. It is avoided to lift the machine tool body 1 to an excessive height to reduce safety hazards.

[0034] It is worth noting that the limit member 6 is also detachably connected to the support sub-base 3 through the lifting guide block 7, which is beneficial to reduce the interference of the limit member 6 when the support shock-absorbing point is located at other positions of the machine tool body 1, thereby ensuring the support of the support sub-base 3 to the machine tool body 1.

[0035] See also Figure 2In order to increase the support and shock-absorbing points for the machine tool body 1, the telescopic rod 4 includes a rod barrel 16 and a sub-rod 17. The sub-rod 17 is slidably connected to the rod barrel 16, and the ends of the rod barrel 16 and the sub-rod 17 that are away from each other are respectively hinged to the support sub-base 3. The top surface of the rod barrel 16 is swung with a support adjustment plate 18, and the top surface of the support adjustment plate 18 is flush with the top surface of the support sub-base 3. The bottom surface of the support adjustment plate 18 is detachably mounted with a second shock-absorbing member 19, and the support adjustment plate 18 is also equipped with a disassembly and assembly mechanism, which is used to disassemble and assemble the second shock-absorbing member 19.

[0036] For details, see Figure 4 and Figure 5 The disassembly and assembly mechanism includes a hemispherical block 20. A slide groove 21 is provided on the top surface of the second shock absorbing member 19, and the hemispherical block 20 is slidably installed in the slide groove 21, and the hemispherical block 20 extends on the top of the second shock absorbing member 19. A first spring 22 is installed in the slide groove 21, one end of the first spring 22 is fixedly connected to the bottom wall of the slide groove 21, and the other end of the first spring 22 is fixedly connected to the bottom surface of the hemispherical block 20. A slot 23 is provided on the bottom surface of the support adjustment plate 18, and the hemispherical block 20 is plugged into the slot 23.

[0037] In order to further lock the hemispherical block 20 in the slot 23, the support and adjustment plate 18 is also equipped with a fixing component, which includes an insertion rod 24. A movable groove 25 is provided on the side wall of the support and adjustment plate 18, and the insertion rod 24 is slidably connected in the movable groove 25. The movable groove 25 is connected to the slot 23, and a third wedge surface 26 is provided at one end of the insertion rod 24 facing the slot 23, and the third wedge surface 26 cooperates with the spherical surface of the hemispherical block 20. A locking groove 27 is provided on the side wall of the hemispherical block 20, and the insertion rod 24 is plugged into the locking groove 27 through the third wedge surface 26. A second spring 28 is sleeved on the side wall of the insertion rod 24, and the second spring 28 is installed in the movable groove 25, and one end of the second spring 28 is fixedly connected to the side wall of the insertion rod 24, and the other end of the second spring 28 is fixedly connected to the slot wall of the slot 23.

[0038] When the machine tool body 1 is subjected to the shock absorbing operation and additional shock absorbing support points of the machine tool body 1 are required, the support adjustment plate 18 is first driven to swing away from the rod barrel 16. At this time, the installation point of the second shock absorbing member 19 is exactly opposite to the shock absorbing support point that needs to be additionally added. Then, the second shock absorbing member 19 is inserted between the support adjustment plate 18 and the ground. During the insertion of the second shock absorbing member 19, the support adjustment plate 18 presses the hemispherical block 20, and the hemispherical block 20 further presses the first spring 22. When the hemispherical block 20 is aligned with the slot 23, the first spring 22 releases the elastic force and drives the hemispherical block 20 to be inserted into the slot 23. When the hemispherical block 20 is inserted into the slot 23, the hemispherical block 20 presses the insertion rod 24, and the insertion rod 24 further presses the second spring 28. When the second spring 28 is aligned with the locking slot 27, the second spring 28 releases the elastic force and drives the insertion rod 24 to be inserted into the locking slot 27. At this time, the second shock absorbing member 19 is fixed to the bottom surface of the support adjustment plate 18 and provides an additional shock absorbing support point for the machine tool body 1 to improve the shock absorbing effect.

[0039] See also Figure 2 and Figure 4 In order to prevent the support and adjustment plate 18 from being displaced by the vibration force of the machine tool body 1 when the support and adjustment plate 18 is not in use, a protrusion 29 is fixedly connected to the bottom surface of the support and adjustment plate 18, and a groove 30 is opened on the top surface of the rod tube 16, and the protrusion 29 is clamped with the groove 30.

[0040] When the support adjustment plate 18 is attached to the top surface of the rod barrel 16, the support adjustment plate 18 is clamped to the top surface of the rod barrel 16 through the protrusion 29. When the support adjustment plate 18 needs to be used, the support adjustment plate 18 is driven to swing away from the rod barrel 16, and the protrusion 29 is separated from the groove 30, and the support adjustment plate 18 is unfixed.

[0041] It is worth mentioning that see Figure 2 The first shock absorbing member 5 and the second shock absorbing member 19 are damping spring shock absorbing members in the art, which include an upper support plate, a damping spring and a lower base plate, and are used for shock absorbing of large machine tools.

[0042] In a second aspect, the present application provides a vibration reduction method for a titanium alloy processing machine tool, comprising the following steps: S1: First, the machine tool body 1 is lifted, and the positions of the four supporting points are determined according to the bottom shape of the machine tool body 1, such as the corner positions of the machine tool body 1. Then, four supporting sub-bases 3 are pre-placed at the four determined supporting points. During the process of adjusting the positions of the four supporting sub-bases 3, the four supporting sub-bases 3 are always connected to each other through the telescopic rods 4; S2: lower the machine tool body 1, and the machine tool body 1 presses the second connecting rod 13 downward by its own gravity. The second connecting rod 13 drives the first connecting rod 9 to move outward through the second wedge surface 15. The first connecting rod 9 then drives the limiting member 6 to rise through the first wedge surface 11 and the lifting wedge surface 12. At this time, the limiting member 6 limits the side of the machine tool body 1, and the shock-absorbing base 2 is placed to shift; S3: Start the machine tool body 1 for the first time and process the titanium alloy. If it is found that it is necessary to add a shock-absorbing support point, close the machine tool body 1, drive the corresponding support adjustment plate 18 to swing to the support point position, and then insert the second shock-absorbing member 19. In the process of inserting the second shock-absorbing member 19, the support adjustment plate 18 squeezes the hemispherical block 20, and the hemispherical block 20 further squeezes the first spring 22. When the hemispherical block 20 is aligned with the slot 23, the first spring 22 releases the elastic force and drives the hemispherical block 20 to be inserted into the slot 23. While the hemispherical block 20 is inserted into the slot 23, the hemispherical block 20 squeezes the insertion rod 24, and the insertion rod 24 further squeezes the second spring 28. When the second spring 28 is aligned with the locking slot 27, the second spring 28 releases the elastic force and drives the insertion rod 24 to be inserted into the locking slot 27. At this time, the second shock-absorbing member 19 is fixed to the bottom surface of the support adjustment plate 18, and provides an additional shock-absorbing support point for the machine tool body 1 to improve the shock-absorbing effect; S4: The machine tool body 1 is started again. When the machine tool body 1 performs titanium alloy processing, the vibration force generated by the machine tool body 1 is first transmitted to the support sub-base 3 and the support adjustment plate 18, and then respectively transmitted to the first shock absorbing member 5 and the second shock absorbing member 19. Finally, the vibration force is damped by the first shock absorbing member 5 and the second shock absorbing member 19.

[0043] In summary, the shock-absorbing base 2 can be applied to machine tool bodies 1 of different models, thereby facilitating the improvement of the convenience of providing shock absorption for titanium alloy processing machine tools of different models.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
