Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a vector vibration table with adjustable angle. Background Art

[0002] A vector vibration table is a test device used to simulate complex vibration environments. The device can generate independent vibrations in multiple vertical axes to reproduce dynamic loads in the real world, such as earthquakes, shocks and vibrations during transportation. Its core advantage is that it can accurately control the frequency, amplitude, phase and direction of vibration, thereby providing a comprehensive vibration resistance evaluation for molding sand. With the continuous advancement of technology, vector vibration tables continue to develop in improving test accuracy, expanding functions and enhancing user experience, becoming an important tool for ensuring product quality and safety.

[0003] Most of the existing vector vibration tables can only evaluate the vibration resistance of the molding sand in a fixed position. The evaluation results are not comprehensive and cannot guarantee the quality and safety of the product. At the same time, when the vibration motor starts working, the vibration generated is likely to affect the mechanical structure of the device, which will reduce the stability of the device and thus pose a safety hazard. Therefore, an angle-adjustable vector vibration table is proposed, which has the effect of multi-angle adjustment and improving the stability of the device.

[0004] The utility model patent with publication number CN214309378U provides an electric vibration table, which adjusts the height of the vibration table body by driving the lead screw to rotate by a driving motor. Although it can meet the needs of operators of different heights, this mechanical transmission method may introduce unexpected friction and response delay.

[0005] The utility model patent with publication number CN217483803U provides a vibration table. Although the vibration table can be moved better by the support rod and moving wheels under the moving mechanism, this design may reduce the stability of the vibration table during the movement. If the structure of the support rod and the moving wheel is not strong enough, it may shake or tilt during the movement, thus affecting the use effect of the vibration table.

[0034] like Figures 1 to 6As shown, the present invention provides an angle-adjustable vector vibration table, comprising an adjustment mechanism 1, a base mechanism 2, a buffer mechanism 3 and a main body mechanism 4, wherein the adjustment mechanism 1 is arranged on the base mechanism 2, the buffer mechanism 3 is arranged inside the base mechanism 2, and the main body mechanism 4 is arranged on the adjustment mechanism 1; the adjustment mechanism 1 comprises a first motor 101, a screw rod 102, a gear 103, a rotating shaft 104, a limiting plate 105, an adjustment frame 106, a rotating frame 107, a second motor 108 and a rotating plate 109, the output shaft of the first motor 101 is fixedly connected with the screw rod 102, the screw rod 102 is meshed with the gear 103, the gear 103 is coaxially fixedly connected with the rotating shaft 104, the rotating shaft 104 is fixedly connected with two limiting plates 105, and both ends of the rotating shaft 104 are fixedly connected with the adjustment frame 106 The main mechanism 4 is fixedly connected to the adjustment frame 106, the rotating shaft 104 is rotatably connected to the rotating frame 107, and two limit plates 105 are respectively arranged on the outer side of the rotating frame 107 to limit the rotating frame 107.

The tops of the four air storage tanks 202 are provided with grooves 203, and the support frame 204 is fixedly connected to the base body 201. Four grooves 203 are distributed on the surface of the base body 201, and the support frame 204 is located between the four grooves 203.

[0035] The main body mechanism 4 includes a connecting plate 401, a vibration motor 402 and a sand box 403. Four vibration motors 402 are fixedly connected to the top of the connecting plate 401, and the top of the vibration motor 402 is fixedly connected to the sand box 403. The four vibration motors 402 are distributed on the top of the connecting plate 401, and the bottom of the connecting plate 401 is fixedly connected to the top of the adjustment frame 106.

[0036] The above scheme is adopted: through the cooperation of structures such as gear 103 and rotating frame 107, the problem that the device can only evaluate the vibration resistance performance of molding sand at a fixed angle is solved. The first motor 101 is started, and the screw rod 102 drives the gear 103 to rotate. The rotation of the gear 103 can drive the adjustment frame 106 to tilt in the longitudinal direction through the rotating shaft 104. At the same time, the second motor 108 is started, and the rotating frame 107 is driven to rotate through the rotating plate 109, and then the adjusting frame 106 is driven to tilt in the lateral direction through the rotating shaft 104, thereby driving the connecting plate 401 to achieve multi-angle tilting, so that the position of the molding sand inside the sand box 403 is changed, and a comprehensive evaluation of the vibration resistance performance of the molding sand in the multi-angle tilt state and during the movement is achieved.

[0037] like Figures 4 to 6 As shown, the buffer mechanism 3 includes a cylinder 301, an air outlet 302, a buffer spring 303, a piston 304, a rotating groove 305, a rotating ball 306, a support plate 307 and a support spring 308. A plurality of air outlet holes 302 are provided on the surface of the cylinder 301. The bottom of the inner wall of the cylinder 301 is elastically connected to the piston 304 through the buffer spring 303. A rotating groove 305 is provided on the top of the piston 304. A rotating ball 306 is rotatably connected in the rotating groove 305. The top of the rotating ball 306 is fixedly connected to the support plate 307. The support plate 307 is connected to the piston 304 through four support springs 308.

[0038] A plurality of air outlet holes 302 are distributed on the inner wall of the cylinder 301 along the circumferential direction. The number of the buffer mechanisms 3 is four, and the tops of the four support plates 307 are respectively against the bottom of the adjustment frame 106 .

[0039] The cylinder 301 is arranged inside the air storage tank 202 , the air outlet 302 is connected to the air storage tank 202 , and the air storage tank 202 is connected to the outside through the throttle port 206 .

[0040] The above scheme is adopted: through the cooperation of structures such as the air storage tank 202 and the buffer mechanism 3, the stability of the device during vibration and tilting is improved. After the support plate 307 is squeezed, the top of the support plate 307 is kept in contact with the bottom of the adjustment frame 106 by rotating the rotating ball 306, and the corresponding support spring 308 is squeezed or stretched to achieve the first level of buffering; at the same time, the adjustment frame 106 squeezes the support plate 307 to make the piston 304 move downward, and the downward movement of the piston 304 will squeeze the buffer spring 303 and the air inside the cylinder 301, so that the air is discharged into the interior of the air storage tank 202 through the air outlet 302. The air storage tank 202 is connected to the outside through the throttle port 206. The throttle port 206 is used to control the gas flow speed, which plays a buffering role on the piston 304, thereby reducing the speed of the adjustment frame 106 when it is tilted, and further improving the stability below the vibration motor 402.

[0041] The working principle and use process of the present invention are as follows: first, pour molding sand into the interior of the sand box 403, and then start the vibration motor 402 to simulate the vibration of the sand box 403. The four vibration motors 402 can generate independent vibrations respectively to reproduce dynamic loads in the real world, such as earthquakes, impacts and vibrations during transportation, etc., thereby providing vibration resistance performance evaluation for the molding sand.

[0042] When it is necessary to conduct an all-round and multi-angle evaluation of the molding sand, it is only necessary to start the first motor 101 so that the screw rod 102 drives the gear 103 to rotate. The rotation of the gear 103 can drive the top of the adjusting frame 106 to tilt in the longitudinal direction through the rotating shaft 104. At the same time, the second motor 108 is started to drive the rotating frame 107 to rotate through the rotating plate 109, and then the adjusting frame 106 is driven to tilt in the lateral direction through the rotating shaft 104, so that the connecting plate 401 can be tilted at multiple angles, so that the position of the molding sand inside the sand box 403 changes.

[0043] At this time, the tilted adjustment frame 106 will squeeze the support plate 307 at its bottom. After being squeezed, the support plate 307 will rotate by rotating the ball 306 to make the top of the support plate 307 continue to fit with the bottom of the adjustment frame 106, and squeeze the support spring 308 below the corresponding tilted state, and stretch other support springs 308 to play the first buffering role. At the same time, the adjustment frame 106 squeezes the rotating frame 107 to make the piston 304 move downward. The downward movement of the piston 304 will squeeze the buffer spring 303 and the air inside the cylinder 301, so that the air is discharged into the interior of the gas storage tank 202 through the air outlet 302, thereby increasing the gas pressure inside the gas storage tank 202. The gas storage tank 202 is connected to the outside through the throttle port 206, and the throttle port 206 is used to control the gas flow rate to support and buffer the piston 304.

[0044] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
