Description

Technical Field

[0001] The utility model belongs to the technical field of vibration test benches, and particularly relates to an angle adjustment structure of a vibration test bench. Background Technique

[0002] In the field of mechanical vibration, it is necessary to conduct vibration tests on some hydrogen storage tanks or other tanks. The tank needs to be fixed on the vibration table so that the tank is rigidly and fixedly connected to the vibration table. The existing fixing methods for the tank and the vibration table mostly use adhesives to bond and fix the tank and the vibration table. Such a fixing method has the problem of insufficient bonding rigidity of the adhesive, which will affect the accuracy of the test of the tank specimen.

[0003] According to a disclosed vibration test bench (publication number: CN110044567A), which includes a load-bearing plate, a jitter assembly, a jitter frame, a scale, a shock-absorbing assembly, a support plate, a bracket, a vibration rod, a vibration spring, an arc-shaped push plate, a vibrator, an eccentric cam, a cross pointer, a tension spring, a telescopic rod, a clamping ball, a spherical clamping block, a motor, a wheel disc, a connecting rod, a vibration plate and a moving clamping block. The load-bearing plate is installed on the top side of the support plate, and the vibrator is fixed on the top side of the support plate. However, in the above device, through the cooperation of components such as the connecting rod, the vibration plate and the moving clamping block, it is difficult to achieve the effect of adjusting the angle of the operation table, it is difficult to achieve rapid switching of multiple angles, and it is difficult to adapt to different experimental conditions and requirements, so it needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an angle adjustment structure of a vibration test bench. By turning the turning handle, the force that drives the bidirectional reciprocating screw rod to rotate by the turning handle cooperates with components such as the threaded block, the mounting plate and the support rod in the adjustment device, realizing the displacement of the support column driven by the displacement of the support rod, and the rotation of the operation table driven by the opposite movement of the two support columns, thus solving the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an angle adjustment structure of a vibration test bench, including a protection plate. A test bench is arranged on the top of the protection plate, an operation table is arranged on the top of the protection plate, and an adjustment device is arranged on the top of the protection plate;

[0007] The adjusting device includes a fixed plate which is fixedly connected to the side of the test bench. A bi-directional reciprocating lead screw penetrates through the side of the fixed plate.

[0010] Further, a spring is fixedly connected to the bottom of the test bench, and one end of the spring away from the test bench is fixedly connected to the top of the protective plate. The reset mechanism of the spring ensures that the test bench can quickly recover after vibration, adapting to continuous testing.

[0011] Further, the initial state of the spring is a relaxed state. The number of the fixed blocks is set to two and they are symmetric with respect to the vertical central axis of the protective plate.

[0012] Further, the number of the support rods is set to two and they are symmetric with respect to the vertical central axis of the protective plate. The shape of the mounting block is set to be semi-circular. Through the design of the support rods and the mounting blocks, the vibration amplitude and frequency of the test bench can be flexibly adjusted to meet different experimental requirements.

[0013] Further, the number of the springs is set to several and they are symmetric with respect to the vertical central axis of the protective plate. The test bench is located on the movement trajectory of the mounting block. The design of the mounting block can reduce the lateral displacement generated during vibration and improve the stability of the test.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model realizes the displacement of the support column driven by the displacement of the support rod and the rotation of the operation table driven by the relative movement of two support columns by the force of rotating the handle to drive the bidirectional reciprocating screw rod to rotate, which is mutually coordinated with components such as the threaded block, mounting plate, and support rod in the adjustment device, achieving the effect of adjusting the angle of the operation table, enabling rapid switching of multiple angles, and adapting to different experimental conditions and requirements.

[0028] The adjusting device 2 includes a fixed plate 201. The fixed plate 201 is fixedly connected to the side of the test bench 102. A bi-directional reciprocating lead screw 203 penetrates through the side of the fixed plate 201.

[0029] One end of the bi-directional reciprocating lead screw 203 is fixedly connected to a rotary handle 202. The bottom of the threaded block 204 is slidably connected to the top of the test bench 102. Through the fine adjustment of the rotary handle 202, high-precision angle adjustment can be achieved, meeting different test requirements, enabling rapid switching of multiple angles, and adapting to different experimental conditions and requirements.

[0030] A vibration structure is provided at the bottom of the test bench 102. The vibration structure includes a mounting plate 210. The side surface of the mounting plate 210 is fixedly connected to the side surface of the protective plate 101. A motor 211 is fixedly connected to the side surface of the mounting plate 210. The output shaft of the motor 211 is fixedly connected to a rotating rod 212. A mounting block 213 is fixedly connected to the circumferential surface of the rotating rod 212. A telescopic rod 214 is fixedly connected to the top of the protective plate 101. The end of the telescopic rod 214 away from the protective plate 101 is fixedly connected to the bottom of the test bench 102.

[0031] A spring 215 is fixedly connected to the bottom of the test bench 102. The end of the spring 215 away from the test bench 102 is fixedly connected to the top of the protective plate 101. The reset mechanism of the spring 215 ensures that the test bench 102 can quickly recover after vibration and adapt to continuous testing.

[0032] The initial state of the spring 215 is a relaxed state. The number of fixing blocks 206 is set to two and they are symmetric with respect to the vertical central axis of the protective plate 101. The drive of the motor 211 and the spring 215 provide a stable and adjustable vibration frequency, ensuring that the test bench 102 can produce a uniform vibration effect during testing.

[0033] The number of support rods 207 is set to two and they are symmetric with respect to the vertical central axis of the protective plate 101.

[0035] A specific application of this embodiment is as follows: In this application, by rotating the throttle grip 202, the throttle grip 202 drives the bidirectional reciprocating lead screw 203 to rotate. Then, the rotation of the bidirectional reciprocating lead screw 203 drives two threaded blocks 204 to move towards each other. The displacement of the threaded blocks 204 drives the fixed rod 205 to displace. Then, the displacement of the fixed rod 205 drives the fixed block 206 to displace. The displacement of the fixed block 206 drives the support rod 207 to displace. Then, the displacement of the support rod 207 drives the support column 208 to displace. The opposite movement of the two support columns 208 drives the operating table 103 to rotate. Reversely rotating the throttle grip 202 makes the two threaded blocks 204 move away from each other, thereby making the operating table 103 rotate in the opposite direction, achieving the function of adjusting the angle of the operating table 103. By driving the rotating rod 212 to rotate through the motor 211, and then driving the mounting block 213 to rotate through the rotating rod 212. When the convex surface of the mounting block 213 presses against the test bench 102, the test bench 102 moves upward. When the convex surface of the mounting block 213 rotates to the bottom, the test bench 102 resets through the elastic force of the spring 215, achieving the function of the test bench 102 jittering up and down, and achieving the effect of vibrating the test bench 102 and the operating table 103.
