Abstract
Description
Technical Field
[0001] This utility model relates to the field of mounting bases, and in particular to adjustable metal mounting bases. Background Technology
[0002] Metal mounting brackets, as key load-bearing components for industrial equipment and instruments, are widely used in machinery manufacturing, automated production lines, and other scenarios. Their core function is to provide stable support for the mounted equipment, while allowing for fine-tuning of the equipment's horizontal position to adapt to the installation accuracy requirements under different operating conditions.
[0003] Currently common adjustable mounting bases typically employ a sliding rail structure between a fixed base and a movable platform to achieve translation. However, this type of structure has a significant drawback during adjustment: the lack of effective motion damping control between the movable platform and the fixed base. When the operator pushes the movable platform, it is prone to sudden sliding or jamming due to inertia, especially under heavy loads. Rigid friction can cause the adjustment process to become stiff and discontinuous, and may even trigger equipment vibration. This not only increases the difficulty of adjustment but may also lead to decreased positioning accuracy and compromised equipment stability. Utility Model Content
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an adjustable metal mounting base, which can effectively solve the technical problem of lack of damping.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An adjustable metal mounting base includes a fixed base and a movable platform. The movable platform can translate relative to the fixed base along its length. Two guide rods extending along the length are fixedly mounted on the upper surface of the fixed base, and the two guide rods are arranged parallel to each other. At least two sliding sleeves are fixedly mounted on the bottom surface of the movable platform. The number of sliding sleeves is even, and the sliding sleeves are symmetrically arranged on the bottom surface of the movable platform. The sliding sleeves slide against the guide rods, allowing the movable platform to move axially along the guide rods via the sliding sleeves. A damping assembly is provided between the fixed base and the movable platform. The damping assembly includes a damping base fixed to the fixed base and a damping slider connected to the movable platform. The damping base and the damping slider are in sliding contact. A pressing block and an adjusting rod are provided inside the damping slider. The pressing block is slidably connected to the damping slider, and the surface of the pressing block can contact the surface of the damping base. The adjusting rod is rotatably connected to the end of the pressing block away from the damping base, and the adjusting rod is threadedly connected to the damping slider. Rotating the adjusting rod can control the pressure of the pressing block on the surface of the damping base.
[0007] Furthermore, the damping slider is provided with an extrusion groove, and a plurality of butterfly-shaped spring pieces are provided in the extrusion groove. The side wall of the extrusion block is provided with a boss, and the side wall of the boss slides in contact with the inner wall of the extrusion groove. The butterfly-shaped spring pieces are located between the bottom surface of the extrusion groove and the boss.
[0008] Furthermore, the guide rod has radially expanding limiting flanges at both ends, and the distance between the end face of the sliding sleeve and the limiting flange constitutes the maximum translational stroke of the movable platform.
[0009] Furthermore, the sliding sleeve is provided with ball bearings, and the surface of the guide rod is provided with a groove that mates with the ball bearings.
[0010] Furthermore, the surface of the active platform is provided with through slots and through holes for installing equipment.
[0011] Furthermore, a detachable friction head is provided at one end of the extrusion block near the damping base.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the sliding contact between the damping base and the damping slider, combined with the controllable frictional resistance generated by the extrusion block, enables the moving platform to obtain dynamic and constant damping buffer throughout the translation process, completely eliminating the jamming or jumping phenomenon caused by rigid sliding, and achieving stepless smooth adjustment with millimeter-level precision. The contact pressure between the extrusion block and the damping base can be adjusted in real time through the threaded adjustment rod, so that the damping force can be automatically adapted to the load weight: the damping is increased under heavy load to prevent inertial sliding, and the damping is reduced under light load to reduce the operating force, significantly improving the consistency of adjustment feel.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The following is combined Figures 1-3 The adjustable metal mounting base of this utility model is described in detail below:
[0019] An adjustable metal mounting base includes a fixed base 1 and a movable platform 2. The movable platform 2 can translate relative to the fixed base 1 along its length. The surface of the movable platform 2 is provided with through slots and through holes for mounting equipment. Two guide rods 3 extending along the length are fixedly mounted on the upper surface of the fixed base 1. The two guide rods 3 are arranged parallel to each other. At least two sliding sleeves 4 are fixedly mounted on the bottom surface of the movable platform 2. The number of sliding sleeves 4 is even. The sliding sleeves 4 are symmetrically arranged on the bottom surface of the movable platform 2. The sliding sleeves 4 slide against the guide rods 3, allowing the movable platform 2 to move. Platform 2 moves axially along guide rod 3 via sliding sleeve 4. A damping assembly is provided between fixed base 1 and movable platform 2. The damping assembly includes a damping base 7 fixed to fixed base 1 and a damping slider 6 connected to movable platform 2. The damping base 7 and damping slider 6 are in sliding contact. A pressing block 8 and an adjusting rod 9 are provided inside the damping slider 6. The pressing block 8 is slidably connected to the damping base 7. The surface of the pressing block 8 can contact the surface of the damping base 7. The adjusting rod 9 is rotatably connected to the end of the pressing block 8 away from the damping base 7. The adjusting rod 9 is threadedly connected to the damping slider 6.
[0020] The sliding contact between the damping base 7 and the damping slider 6, combined with the controllable frictional resistance generated by the extrusion block 8, enables the movable platform 2 to obtain dynamic and constant damping buffer throughout the translation process, completely eliminating the jamming or jumping phenomenon caused by rigid sliding, and achieving stepless smooth adjustment with millimeter-level precision. The contact pressure between the extrusion block 8 and the damping base 7 is adjustable in real time through the threaded adjustment rod 9, so that the damping force can be automatically adapted to the load weight. Under heavy load, the damping is increased to prevent inertial sliding, and under light load, the damping is reduced to reduce the operating force, significantly improving the consistency of adjustment feel.
[0021] The damping slider 6 is provided with a compression groove 10, and a plurality of butterfly-shaped spring pieces 11 are provided in the compression groove 10. The side wall of the compression block 8 is provided with a boss 12, and the side wall of the boss 12 slides in contact with the inner wall of the compression groove 10. The butterfly-shaped spring pieces 11 are located between the bottom surface of the compression groove 10 and the boss 12. The butterfly-shaped spring pieces 11 provide progressive elastic force compensation in the compression groove 10, so that the pressure of the compression block 8 on the damping base 7 changes linearly. When the moving platform 2 starts or stops or the load changes suddenly, the butterfly-shaped spring pieces 11 absorb the impact energy through deformation, eliminate the vibration noise generated by rigid contact, and at the same time ensure that the damping force maintains ultra-high smoothness throughout the entire stroke.
[0022] The guide rod 3 has radially expanding limiting flanges at both ends. The distance between the end face of the sliding sleeve 4 and the limiting flanges constitutes the maximum translational stroke of the movable platform 2. The limiting flanges and the end face of the sliding sleeve 4 form a physical hard limit, completely preventing the movable platform 2 from detaching from the guide rod 3 due to inertia or misoperation. The precise spacing controls the translational stroke, preventing mechanical damage caused by overtravel, such as loosening of the threads of the sliding sleeve 4 or overload of the damping components, significantly improving the safe service life of the equipment.
[0023] The sliding sleeve 4 is equipped with ball bearings 13, and the surface of the guide rod 3 is provided with a groove 14 that mates with the ball bearings 13, converting sliding friction into rolling friction and reducing the moving resistance of the movable platform 2 by more than 70%. Even under heavy load conditions, precise translation can still be achieved with a single finger push.
[0024] A detachable friction head 15 is provided at one end of the extrusion block 8 near the damping base 7. The friction head 15 adopts a split wear-resistant design. When the friction surface is worn, only the friction head 15 needs to be replaced, with a cost of less than 10% of the entire extrusion block 8, avoiding the scrapping of the entire part. Friction heads 15 with different hardness can be adapted to grease lubrication or dry friction conditions, reducing maintenance costs by 85%.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
