Description

Technical Field

[0001] This application relates to the technical field of support bases for high-speed machining centers, specifically a highly stable and earthquake-resistant base for high-speed machining centers. Background Technology

[0002] When machining deep and steep cavities, high-speed machining centers can create optimal machining conditions for end mills by using the additional rotation and oscillation of the workpiece or spindle head, and avoid collisions between the tool and tool holder and the cavity wall, reducing tool vibration and the risk of tool breakage. However, any shaking during machining will seriously affect the accuracy of the machining center. Therefore, it is necessary to reduce the shaking of the machining center during high-speed milling or rotation, and a highly stable anti-vibration base should be installed at the bottom of the high-speed machining center.

[0003] Existing high-stability anti-vibration bases for high-speed machining centers typically only achieve vibration reduction by using damping rods in conjunction with shock-absorbing springs. They cannot restrict or reinforce the stroke angle of the damping rods. After long-term operation, the outer tube and inner rod of the damping rod will wear due to the tilting of the stroke angle, affecting the vibration reduction effect of the anti-vibration base. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a high-stability anti-vibration base for high-speed machining centers. This base features the ability to restrict and reinforce the stroke angle of the damping rod, improving its stability during operation and preventing wear between the outer and inner tubes due to stroke angle inclination. This ensures the vibration reduction effect of the anti-vibration base. It solves the problem that existing high-stability anti-vibration bases for high-speed machining centers typically only rely on damping rods and damping springs for vibration reduction, failing to restrict and reinforce the stroke angle of the damping rod. This results in wear between the outer and inner tubes due to stroke angle inclination after prolonged operation, affecting the vibration reduction effect of the anti-vibration base.

[0005] To achieve the aforementioned goal of limiting and reinforcing the stroke angle of the damping rod, improving its stability during operation, preventing wear between the outer tube and inner rod due to tilting of the stroke angle, and ensuring the vibration reduction effect of the seismic base, this application provides the following technical solution: A high-stability seismic base for a high-speed machining center, comprising a base plate, a support plate above the base plate, damping rods at the four corners of the base plate and the support plate, the bottom of the outer tube of the damping rod being disposed on the top of the support plate, the bottom of the support plate being disposed on the top of the base plate via an installation assembly, and the top of the inner rod of the damping rod being disposed on the bottom of the support plate via an installation assembly. A high-speed machining center is mounted on the top of the plate. Four support rods are hinged to the outer surface of the middle part of the inner rod of the damping rod via a hinge frame. The four support rods are arranged in a circular array around the damping rod. A sliding frame is hinged to the end of each support rod away from the inner rod of the damping rod via the hinge frame. The inner wall of the middle part of the sliding frame is slidably disposed on the outer surface of the middle part of the sliding rod. Both ends of the sliding rod are disposed on the top of the support plate via fixing plates. A shock-absorbing spring is sleeved on the outer side of the inner rod of the damping rod. One end of the shock-absorbing spring is disposed at the bottom of the fixing ring. The fixing ring is disposed on the outer surface of the middle part of the inner rod of the damping rod. The other end of the shock-absorbing spring is disposed at the top of the outer tube of the damping rod.

[0006] Through the above scheme, the extension and retraction of the damping rod can drive the support rod to swing. At the same time, the swing angle of the support rod can be limited by the sliding frame and sliding rod. Furthermore, the four support rods arranged in a ring array on the outer surface of the middle of the inner rod of the damping rod can support and fix the stroke angle of the inner rod of the damping rod. This achieves the goal of limiting and reinforcing the stroke angle of the damping rod, improving the stability of the damping rod during operation, and preventing wear between the outer tube and the inner rod of the damping rod due to the tilt of the stroke angle, thus ensuring the vibration reduction effect of the seismic base.

[0007] Furthermore, the mounting assembly includes a plug-in block and a mounting frame. The plug-in block is inserted into the inner wall of the middle part of the mounting frame. The plug-in block and the mounting frame are fixedly connected by fastening bolts. The plug-in block is located at the top of the inner rod of the damping rod and the bottom of the support plate. The mounting frame is located at the bottom of the support plate and the top of the base plate.

[0008] With the above solution, the plug-in block can be easily removed from the mounting frame by tightening the fastening bolts between the mounting frame and the plug-in block. This allows for easy removal of the damping rod and support plate from between the base plate and the support plate, facilitating the maintenance and replacement of the damping rod and its associated connecting parts.

[0009] Furthermore, an external thread is provided on the outer surface of one end of the damping rod outer tube, and a threaded collar is connected to the outer surface of one end of the damping rod outer tube through the external thread. A hook is rotatably provided on the top of the threaded collar through a rotating ring. The hook is L-shaped, and the short side of the hook is located above the fixed ring.

[0010] With the above solution, the height of the hook can be adjusted by rotating the threaded collar in conjunction with the external thread. The hook can then drive the damping rod to retract through the fixed ring, shortening the distance between one end of the inner rod of the damping rod and the support plate. This allows the damping rod and support plate to be easily removed from between the base plate and the support plate, avoiding the influence of the installation components when disassembling the damping rod and support plate.

[0011] Furthermore, the outer surface of the middle part of the long side of the hook is slidably disposed within the inner wall of the middle part of the limiting frame, and the limiting frame is disposed on the outer surface of the middle part of the fixing ring.

[0012] The above method allows the hook's movement trajectory to be fixed by sliding the outer surface of the middle part of the long side of the hook within the inner wall of the middle part of the limiting frame, thereby improving the stability of the hook's movement.

[0013] Furthermore, a turbine ring is rotatably mounted on the top of the support plate. The turbine ring is located below the threaded collar. A limiting telescopic rod is provided between the turbine ring and the threaded collar. One end of the outer tube of the limiting telescopic rod is located on the top of the turbine ring, and one end of the inner tube of the limiting telescopic rod is located on the bottom of the threaded collar.

[0014] With the above scheme, the rotation of the turbine ring can be coordinated with the limit telescopic rod to drive the threaded collar to rotate, and the contraction of the limit telescopic rod can adapt to the constantly changing distance between the turbine ring and the threaded collar.

[0015] Furthermore, a worm gear is rotatably mounted on the top of the support disk via a connecting plate, and the worm gear meshes with the turbine ring.

[0016] The above scheme allows the turbine ring to rotate by rotating the worm gear, which in turn drives the threaded collar to rotate via the limit telescopic rod, thus facilitating the rotation of the turbine ring.

[0017] Furthermore, the outer surface of the middle part of the slide rod is quadrilateral, and the shape of the outer surface of the middle part of the slide rod is adapted to the shape of the inner wall of the middle part of the slide frame.

[0018] The above scheme effectively prevents the sliding frame from rotating circumferentially during sliding by using a quadrilateral cross-section sliding rod and a sliding frame, ensuring that the support rod always swings along the preset radial plane.

[0019] Furthermore, hydraulic rods corresponding to the positions of four damping rods are provided at the four corners between the base plate and the support plate, and the bottom of the outer tube of the hydraulic rod is located at the top of the base plate.

[0020] The above solution allows for temporary support of the support plate when the damping rod fails or needs maintenance.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This high-stability, seismic-resistant base for a high-speed machining center utilizes the extension and retraction of a damping rod to drive the support rod to swing. Simultaneously, a sliding frame and sliding rod limit the swing angle of the support rod. Furthermore, four support rods arranged in a ring array on the outer surface of the inner rod of the damping rod support and fix the stroke angle of the inner rod. This achieves the goal of limiting and reinforcing the stroke angle of the damping rod, improving its stability during operation, preventing wear between the outer tube and inner rod due to tilting at the stroke angle, and ensuring the effective vibration reduction of the seismic base.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes a high-stability, earthquake-resistant base for a high-speed machining center, comprising a base plate 1, a support plate 2 above the base plate 1, damping rods 3 at the four corners of both the base plate 1 and the support plate 2, the bottom of the outer tube of the damping rod 3 being positioned on the top of a support plate 4, the bottom of the support plate 4 being mounted on the top of the base plate 1 via an mounting assembly 5, the top of the inner rod of the damping rod 3 being mounted on the bottom of the support plate 2 via the mounting assembly 5, and a high-speed machining center mounted on the top of the support plate 2. Four support rods 8 are hinged to the outer surface of the middle portion of the inner rod of the damping rod 3 via a hinge frame. A support rod 8 is arranged in a ring array around the damping rod 3. The end of the support rod 8 away from the inner rod of the damping rod 3 is hinged to a sliding frame 9 through a hinge frame. The inner wall of the middle part of the sliding frame 9 is slidably set on the outer surface of the middle part of the sliding rod 10. The two ends of the sliding rod 10 are set on the top of the support plate 4 through fixing plates. A shock-absorbing spring 7 is sleeved on the outer side of the inner rod of the damping rod 3. One end of the shock-absorbing spring 7 is set at the bottom of the fixing ring 6. The fixing ring 6 is set on the outer surface of the middle part of the inner rod of the damping rod 3. The other end of the shock-absorbing spring 7 is set on the top of the outer tube of the damping rod 3.

[0032] Please see Figure 2 , Figure 4 and Figure 5 The mounting component 5 includes a plug-in block 501 and a mounting frame 502. The plug-in block 501 is inserted into the inner wall of the middle part of the mounting frame 502. The plug-in block 501 and the mounting frame 502 are fixedly connected by fastening bolts. The plug-in block 501 is located at the top of the inner rod of the damping rod 3 and the bottom of the support plate 4. The mounting frame 502 is located at the bottom of the support plate 2 and the top of the base plate 1. By tightening the fastening bolts between the mounting frame 502 and the plug-in block 501, the plug-in block 501 can be easily removed from the mounting frame 502. This allows for easy removal of the damping rod 3 and the support plate 4 from between the base plate 1 and the support plate 2, facilitating the maintenance and replacement of the damping rod 3 and its associated connecting parts.

[0033] Please see Figure 2 , Figure 4 and Figure 5 The outer surface of one end of the outer tube of the damping rod 3 is provided with an external thread 11. A threaded collar 12 is threadedly connected to the outer surface of one end of the outer tube of the damping rod 3 through the external thread 11. A hook 13 is rotatably provided on the top of the threaded collar 12 through a rotating ring. The hook 13 is L-shaped, and the short side of the hook 13 is located above the fixed ring 6. The height of the hook 13 can be adjusted by rotating the threaded collar 12 in conjunction with the external thread 11, so that the hook 13 can drive the damping rod 3 to retract through the fixed ring 6, shortening the distance between one end of the inner rod of the damping rod 3 and the support plate 4. This allows the damping rod 3 and the support plate 4 to be easily removed from the base plate 1 and the support plate 2, avoiding the influence of the installation component 5 when removing the damping rod 3 and the support plate 4.

[0034] Please see Figure 2 , Figure 3 and Figure 4 The outer surface of the middle part of the long side of the hook 13 is slidably disposed within the inner wall of the middle part of the limiting frame 14. The limiting frame 14 is disposed on the outer surface of the middle part of the fixing ring 6. By sliding the outer surface of the middle part of the long side of the hook 13 within the inner wall of the middle part of the limiting frame 14, the trajectory of the hook 13 can be fixed, thereby improving the stability of the hook 13 during movement.

[0035] Please see Figure 2 , Figure 4 and Figure 5 A turbine ring 15 is rotatably mounted on the top of the support plate 4. The turbine ring 15 is located below the threaded collar 12. A limiting telescopic rod 17 is provided between the turbine ring 15 and the threaded collar 12. One end of the outer tube of the limiting telescopic rod 17 is located on the top of the turbine ring 15, and one end of the inner tube of the limiting telescopic rod 17 is located on the bottom of the threaded collar 12. The rotation of the turbine ring 15 can cooperate with the limiting telescopic rod 17 to drive the threaded collar 12 to rotate. At the same time, the contraction of the limiting telescopic rod 17 can adapt to the constantly changing distance between the turbine ring 15 and the threaded collar 12.

[0036] Please see Figure 2 , Figure 3 and Figure 4 The top of the support plate 4 is rotatably equipped with a worm gear 16 via a connecting plate. The worm gear 16 meshes with the turbine ring 15. By rotating the worm gear 16, the turbine ring 15 can be driven to rotate, which in turn can drive the threaded collar 12 to rotate via the limit telescopic rod 17, thus conveniently driving the turbine ring 15 to rotate.

[0037] Please see Figure 2 , Figure 3 and Figure 4 The outer surface of the middle part of the slide rod 10 is quadrilateral. The shape of the outer surface of the middle part of the slide rod 10 is adapted to the shape of the inner wall of the middle part of the slide frame 9. The matching design of the quadrilateral cross section slide rod 10 and the slide frame 9 can effectively prevent the slide frame 9 from rotating circumferentially during the sliding process, and ensure that the support rod 8 always swings along the preset radial plane.

[0038] Please see Figure 2 and Figure 3 Hydraulic rods 18 are provided at the four corners between the base plate 1 and the support plate 2, corresponding to the positions of the four damping rods 3. The bottom of the outer tube of the hydraulic rod 18 is located at the top of the base plate 1. The hydraulic rods 18 can provide temporary support for the support plate 2 when the damping rods 3 fail or need maintenance.

[0039] In this embodiment, a high-stability anti-vibration base for a high-speed machining center utilizes the extension and retraction of the damping rod 3 to drive the support rod 8 to swing. Simultaneously, the sliding frame 9, in conjunction with the sliding rod 10, restricts the swing angle of the support rod 8. Furthermore, the four support rods 8 arranged in a circular array on the outer surface of the inner rod of the damping rod 3 support and fix the stroke angle of the inner rod of the damping rod 3. This achieves the goal of limiting and reinforcing the stroke angle of the damping rod 3, improving the stability of the damping rod 3 during operation, preventing wear between the outer tube and inner rod of the damping rod 3 due to the tilting of the stroke angle, and ensuring the vibration reduction effect of the anti-vibration base.

[0040] The working principle of the above embodiment is as follows: When the high-speed machining center vibrates during operation, the extension and retraction of the damping rod 3, in conjunction with the shock-absorbing spring 7, provides shock absorption and buffering for the support plate 2, ensuring the stability of the high-speed machining center during operation. When the damping rod 3 extends and retracts due to vibration, the inner rod of the damping rod 3 drives the corresponding four support rods 8 to swing, causing the support rods 8 to drive the slide frame 9 to slide on the outer surface of the middle part of the slide rod 10. The four support rods 8 on the outer side of the inner rod of the damping rod 3 then support the displacement of the inner rod of the damping rod 3, fixing the angle of movement of the inner rod of the damping rod 3. When the damping rod 3 and its associated components need to be repaired or replaced, the hydraulic rod 18 corresponding to the damping rod 3 operates, and the inner rod of the hydraulic rod 18 extends to support the support plate 2. The top of the inner rod of the damping rod 3 and the support... The fastening bolts on the bottom mounting component 5 of the support plate 4 are removed, and the fixed connection between the plug block 501 and the mounting frame 502 is released. The worm gear 16 is rotated, which drives the turbine ring 15 to rotate. The turbine ring 15 drives the threaded collar 12 to rotate through the limiting telescopic rod 17. When the threaded collar 12 rotates, it will adjust the height of the hook 13 in conjunction with the external thread 11, which will drive the hook 13 to move downward. The short side of the hook 13 pushes the fixing ring 6 downward, causing the inner rod of the damping rod 3 to begin to move downward and retract, shortening the distance between the top of the inner rod of the damping rod 3 and the support plate 4. This allows the plug block 501 at the top of the inner rod of the damping rod 3 to be pulled out of the corresponding mounting frame 502. Then, the support plate 4 is lifted upward, allowing the plug block 501 at the bottom of the support plate 4 to be pulled out of the corresponding mounting frame 502, thus completing the disassembly of the damping rod 3 and its auxiliary components.
