Description

Technical Field

[0001] This utility model relates to an angle-adjustable hydraulic vibration table. Background Technology

[0002] Similar to displays, projectors, solar panels, and cameras in optical and display equipment; fan blades, cutting tools, and conveyor belts in industrial machinery; stair railings and bathroom products in building furniture; and wings, propellers, and rearview mirrors in the transportation sector, all require installation at specific angles in actual working conditions. Third-party laboratories providing vibration testing services encounter a wide range of user demands, often for a single product, with multiple installation angle requirements. Typically, these products are repositioned using external fixtures during horizontal vibration testing to achieve operational stability testing at different installation angles. This approach addresses user needs. However, if a user has many products and numerous installation angle requirements, different fixtures are needed for testing. This increases testing costs and consumes vibration table thrust, requiring users to purchase vibration tables with greater thrust to compensate for the thrust required for fixture vibration. Furthermore, installing fixtures increases vibration transmission, potentially leading to under-testing or over-testing.

[0003] In view of this, it is necessary to improve the existing angle-adjustable hydraulic vibration table to solve the above problems. Utility Model Content

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figures 1 to 11 As shown, the angle-adjustable hydraulic vibration table 100 of this utility model includes a base 1, a rotary actuator 2 disposed on the base 1, a rotary seat 3 disposed on the base 1 and driven to rotate by the rotary actuator 2, a linear guide rail 4 disposed on the rotary seat 3, a hydraulic vibrator 5 disposed on the rotary seat 3, and a worktable 6 that can reciprocate relative to the linear guide rail 4. The axis of the rotary seat 3 is parallel to the horizontal plane, and the extension direction of the linear guide rail 4 is parallel to the axis of the rotary seat 3.

[0021] The base 1 serves as a support, and the rotary actuator 2 drives the rotary seat 3 to rotate, thereby adjusting the angle of the worktable 6 and the items on the worktable 6.

[0022] The hydraulic vibrator 5 is mounted on the rotating seat 3 and can rotate with the rotating seat 3, thereby maintaining the relative angle with the worktable 6 and ensuring that the force is uniform in the direction of movement.

[0023] The hydraulic vibrator 5 drives the worktable 6 to reciprocate horizontally, achieving the horizontal vibration requirements of the specimens to meet different horizontal angle requirements. Furthermore, the hydraulic vibrator 5 can rotate together with the worktable 6, directly exciting the worktable 6 and avoiding excitation deviations caused by complex connections.

[0024] like Figure 8 As shown, to fix the base 1, the bottom of the base 1 in this embodiment is provided with a plurality of mounting grooves 11, each mounting groove 11 having an opening facing the side, and a mounting hole 12 penetrating through the bottom of the mounting groove 11. The base 1 can be fixed to the ground by anchor bolts.

[0025] The base 1 is generally cubic in shape, and the upper surface of the base 1 is arc-shaped to form a rotating groove 13. The shape of the rotating groove 13 is preferably matched with the rotating seat 3. The rotating seat 3 is placed in the rotating groove 13.

[0026] The base 1 is provided with baffles 14 extending upward from both ends of the rotating seat 3, and the rotating seat 3 is located axially between the baffles 14 on both sides.

[0027] The baffle 14 has a scale 141 along the circumferential direction, and the rotating seat 3 has a pointer 31 pointing to the scale 141 at its axial end. When the rotating seat 3 is rotated to different positions, the pointer 31 points to different scales 141, which makes it easy for the user to observe and judge the angle of deviation of the rotating seat 3.

[0028] In this embodiment, the maximum offset angle on both sides of the rotary seat 3 is 45 degrees, and the scale 141 is set to -45 degrees to 45 degrees, or -90 degrees to 90 degrees. When the rotary seat 3 is in a state that can keep the worktable 6 horizontal, the pointer 31 points to 0 degrees. In other embodiments, the maximum offset angle of the rotary seat 3 can be adjusted.

[0029] like Figures 7 to 9 As shown, furthermore, to ensure a relatively stable working environment for the hydraulic vibrator 5 on the rotating seat 3, in this embodiment, the rotating seat 3 is provided with multiple locking holes 32 at both ends along the axial direction, and the baffle 14 is provided with multiple through holes 142 along the circumferential direction. The angle-adjustable hydraulic vibration table 100 also includes screws 7 for passing through the through holes 142 and fixing to the locking holes 32. After the rotating seat 3 is rotated into position, the baffle 14 and the rotating seat 3 are fixed by the screws 7 to prevent the rotating seat 3 from shaking during the operation of the hydraulic vibrator 5, thus avoiding test deviations caused by the shaking of the rotating seat 3.

[0030] The through-hole 142 extends in a circumferential direction, and there are multiple through-holes 142. With this configuration, the rotating seat 3 can be fixed in place by multiple screws 7 at any position, resulting in better fixation.

[0031] In this embodiment, the rotating seat 3 includes a semi-cylindrical rotating part 33 and two supporting parts 34 disposed on the rotating part 33. The arc surface of the rotating part 33 faces downward and the plane faces upward. The supporting parts 34 are disposed on the plane of the rotating part 33 and are spaced apart. The linear guide rail 4 is disposed on the supporting parts 34.

[0032] The rotating part 33 is housed in the rotating groove 13, and the locking holes 32 are provided at both ends of the rotating part 33 along the axial direction.

[0033] The rotating base 3 is provided with multiple weight-reducing holes 35, and multiple grease injection channels 36 are radially penetrating the plane of the rotating part 33. The weight-reducing holes 35 can be formed on the rotating part 33 or on the supporting part 34. In this embodiment, the weight-reducing holes 35 are formed on both the rotating part 33 and the supporting part 34, and are axially penetrating, thus reducing the weight of the rotating base 3. Of course, the grease injection channels 36 are not limited to being formed on the rotating part 33; they can also be formed on the supporting part 34 and penetrate the rotating part 33.

[0034] The grease injection channel 36 is arranged radially through the channel, allowing grease to enter the rotating groove 13 for rotational lubrication and rust prevention.

[0035] The two support parts 34 are spaced apart, and the hydraulic vibrator 5 is fixedly installed between the two support parts 34.

[0036] Each of the support portions 34 is provided with two linear guide rails 4 spaced apart. That is, in this embodiment, the angle-adjustable hydraulic vibration table 100 is provided with four linear guide rails 4. The worktable 6 is mounted on the linear guide rails 4 and can move along the extension direction of the linear guide rails 4. like Figure 11 As shown, the rotary actuator 2 includes a mounting base 21 fixed on the base 1, a motor 22 mounted on the mounting base 21, a rotating shaft 23 connected to the rotating seat 3, a pulley 24 connecting the rotating shaft 23, and a belt 25 connecting the pulley 24 and the rotating shaft 23. The mounting base 21 is fixed on the baffle 14. In this embodiment, the operation of the motor 22 drives the belt 25, pulley 24, and rotating shaft 23 to rotate, thereby driving the rotating seat 3 and the worktable 6 on it to rotate. In this embodiment, the motor 22 can drive the rotating seat 3 to achieve stepless angle adjustment, meeting the horizontal vibration requirements for different angles and durations.

[0037] When the specimen needs to be installed at an angle along the horizontal direction of vibration, the rotating seat 3 can be rotated by the rotating actuator 2 to rotate by the corresponding angle, and then the locking holes 32 arranged on both ends of the rotating seat 3 can be locked with screws 7. In this way, when the horizontal vibration is performed, the rotating seat 3 can be firmly connected to the base 1 and play the role of the reaction force support side.

[0038] The adjustable hydraulic vibration table 100 of this invention can realize horizontal vibration tests for different angles, avoiding the problem of needing to adapt different tooling for different angles. The elimination of tooling reduces the output of the vibration table thrust, thereby reducing the purchase cost and energy consumption of the vibration table.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
