Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing foot technology, and in particular to a structure for a mounting foot shock absorber. Background Technology

[0002] Mounting feet are widely used in various machine tools, precision instruments, and mechanical devices requiring vibration isolation and leveling. Their main function is to provide support for the equipment, adjust its level, and reduce the transmission of vibrations from the equipment during operation to the ground. Existing mounting feet typically consist of a threaded rod, the upper end of which is threaded to the equipment base, and the lower end is fitted with a ball joint base, the bottom of which is fixed with a shock-absorbing pad.

[0003] In this type of structure, the ball joint base is connected to the end of the threaded rod via a spherical joint, allowing the vibration damping pad to adjust its tilt angle within a certain range with the ball joint base. This adapts to different ground inclinations and improves the adaptability of equipment installation. Vibration damping pads are generally made of rubber, polyurethane, or composite materials and are used to absorb vibrations generated during equipment operation.

[0004] However, existing ball joint mounting feet still have some shortcomings in long-term use: on the one hand, the ball joint connection is a movable pair, and after installation, the main supporting force of the equipment is concentrated at the ball joint contact part, resulting in concentrated force and large friction and wear, which can easily lead to a shortened life of the ball joint components; on the other hand, since the ball joint itself has rotational freedom, when subjected to equipment vibration, the position of the ball joint is prone to slight displacement or loosening, causing unstable equipment support and affecting the operating accuracy and safety of the equipment. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of short lifespan and unstable support of the mounting feet in the existing technology, and to propose a mounting foot shock absorber structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mounting foot shock absorber structure includes a threaded rod, a ball joint base mounted on the bottom of the threaded rod, a shock-absorbing plate mounted on the bottom of the ball joint base, and a support assembly provided on the threaded rod between the mounting head and the ball joint base. The support assembly is at least partially threaded to the threaded rod. After the mounting foot is installed, the support assembly at least partially abuts against the ball joint base.

[0008] The support assembly includes a second nut and a support member. The second nut is threadedly connected to the threaded rod. The support member is located between the second nut and the ball joint base. After the mounting feet are installed, the support member at least partially abuts against the ball joint base.

[0009] The second nut includes a nut portion that is fixed or integrally formed and an outer protruding cylindrical portion. The outer protruding cylindrical portion is located below the nut portion. The nut portion is threadedly connected to the threaded rod. The support member includes a support cylinder that is fixed or integrally formed and a disc portion. A through hole is provided in the middle of the disc portion. The outer protruding cylindrical portion is inserted into the through hole. The support cylinder points towards the ball joint base.

[0010] The end of the support cylinder away from the disc body has a chamfered arc surface. After the mounting feet are installed, the chamfered arc surface at least partially abuts against the ball joint base.

[0011] The ball joint base includes a ball joint seat, and the bottom end of the threaded rod is fixedly connected to or integrally formed with a ball joint. The ball joint is installed in the ball joint seat, and the shock-absorbing plate is installed at the bottom of the ball joint seat.

[0012] The shock-absorbing plate is a rubber pad.

[0013] The upper part of the threaded rod is threaded with a first nut.

[0014] The present invention discloses a mounting foot shock absorber structure, which has the following advantages: By adding a support component between the threaded rod and the ball joint base, the support component and the ball joint base form a direct contact load-bearing channel after the equipment is installed. This avoids all loads being concentrated on the ball joint, reducing wear and extending the life of the ball joint structure. Simultaneously, the support component can, to a certain extent, limit the minute displacement of the ball joint base during operation, improving support stability and reducing vibration and offset during equipment operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-2A mounting foot shock absorber structure includes a threaded rod 1, a ball joint base 13 mounted on the bottom of the threaded rod 1, and a shock-absorbing plate 6 mounted on the bottom of the ball joint base 13. In one embodiment, the ball joint base 13 includes a ball joint seat 5. A ball joint 4 is fixedly connected to or integrally formed at the bottom end of the threaded rod 1 and is installed inside the ball joint seat 5. The shock-absorbing plate 6 is mounted on the bottom of the ball joint seat 5. A support component 14 is provided on the threaded rod 1 between the mounting head and the ball joint base 13. The support component 14 is at least partially threaded to the threaded rod 1. After the mounting foot is installed, the support component 14 at least partially abuts against the ball joint base 13.

[0020] The lower end of the threaded rod 1 is connected to the damping plate 6 via a ball joint base 13. The ball joint base 13 can adjust its angle according to the ground tilt to adapt to support surfaces with different inclinations. A support assembly 14 is provided on the threaded rod 1 between the mounting head and the ball joint base 13. The support assembly 14 is threadedly connected to the threaded rod 1. After the mounting feet are installed, the support assembly 14 presses downward and at least partially abuts against the ball joint base 13, thereby providing additional support to the ball joint base 13 while supporting the ball joint pair. In this way, when bearing the weight of the equipment and working vibrations, the supporting force can be simultaneously distributed between the ball joint pair and the support assembly 14, reducing the concentrated force on the ball joint pair 4 and improving the overall load-bearing and support stability.

[0021] This mounting foot shock absorber structure adds a support component 14 between the threaded rod 1 and the ball joint base 13. After the equipment is installed, the support component 14 and the ball joint base 13 form a direct contact load-bearing channel, preventing all loads from being concentrated on the ball joint 4, reducing wear on the ball joint 4, and thus extending the life of the ball joint structure. At the same time, the support component 14 can, to a certain extent, limit the slight displacement of the ball joint base 13 during operation, improve support stability, and reduce vibration and offset during equipment operation.

[0022] The support assembly 14 includes a second nut 12 and a support member 9. The second nut 12 is threadedly connected to the threaded rod 1. The support member 9 is located between the second nut 12 and the ball joint base 13. After the mounting feet are installed, the support member 9 at least partially abuts against the ball joint base 13. The second nut 12 includes a nut part 11 that is fixed or integrally formed and an outer protruding cylinder part 3. The outer protruding cylinder part 3 is located below the nut part 11. The nut part 11 is threadedly connected to the threaded rod 1. The support member 9 includes a support cylinder 8 that is fixed or integrally formed and a disc part 10. A through hole is opened in the middle of the disc part 10. The outer protruding cylinder part 3 is inserted into the through hole. The support cylinder 8 points towards the ball joint base 13.

[0023] The second nut 12 is threadedly connected to the threaded rod 1, and its position can be adjusted up and down along the threaded rod 1 during installation. The support member 9 is located between the second nut 12 and the ball joint base 13. After the mounting feet are installed, the support member 9 at least partially abuts against the ball joint base 13. The second nut 12 includes a nut part 11 and an outwardly protruding cylindrical part 3. The outwardly protruding cylindrical part 3 is located below the nut part 11. The nut part 11 is threadedly connected to the threaded rod 1 to achieve axial position adjustment. The support member 9 includes a support cylinder 8 and a disc part 10. A through hole is opened in the middle of the disc part 10. The outwardly protruding cylindrical part 3 is inserted into the through hole. The support cylinder 8 points towards the ball joint base 13, so that when the support assembly 14 is axially loaded, the support cylinder 8 can directly transfer part of the load from the threaded rod 1 to the ball joint base 13, thereby sharing the weight and vibration load of the equipment with the ball joint pair.

[0024] By setting a support assembly 14 consisting of a second nut 12 and a support member 9 between the threaded rod 1 and the ball joint base 13, the supporting force of the mounting foot under load not only depends on the ball joint pair, but can also act directly on the ball joint base 13 through the support member 9, thus achieving load sharing. This can effectively reduce the concentrated force on the ball joint pair, reduce the wear of the ball joint 4, extend its service life, and at the same time improve the support stability of the equipment during operation, reducing equipment vibration and accuracy deviation caused by small displacements.

[0025] The end of the support cylinder 8 away from the disc body 10 has a chamfered surface 7. After the mounting feet are installed, the chamfered surface 7 at least partially abuts against the ball joint base 13. The shock-absorbing plate 6 is a rubber pad. The upper part of the threaded rod 1 is threaded with a first nut 2. The chamfered surface 7 at the end of the support cylinder 8 away from the disc body 10 provides stable support for the ball joint base 13 after the mounting feet are installed. The chamfered surface 7 ensures stable support contact and avoids localized stress caused by processing or installation errors. In addition, the upper part of the threaded rod 1 is threaded with a first nut 2, which can abut against the support leg of the equipment for locking and limiting.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
