Description

Technical Field

[0001] This utility model belongs to the field of test support technology, and in particular relates to an anti-vibration coupling test support structure. Background Technology

[0002] Coupled testing is a testing method that simulates real complex working conditions. Its core is to evaluate the performance of the test component under multiple superimposed and interacting factors by simultaneously applying two or more mutually influential physical actions (such as vibration, temperature, force, etc.), rather than testing a single factor independently, which is closer to the actual use scenario of the product.

[0003] Fix the support base to the test bench or ground with bolts. If the base has positioning holes / vibration damping structure, ensure that the mounting surface is flat and that the vibration damping element and positioning hole are properly aligned to prevent the support from shaking. According to the test direction, insert the exciter into the positioning hole of the support (or fix it in the designated position). Connect the exciter to the test piece through a flexible joint or force sensor, ensuring that the excitation direction is perpendicular to the force-bearing surface of the test piece and there is no eccentricity. Fix the test piece to the test area of ​​the support using bolts, symmetrical clamps, etc., ensuring accurate installation and appropriate fixing force. Check the condition of the dual-point vibration damping elements to ensure that the spring damper is not stuck, the rubber pad is not aged, and that the degree of freedom of the vibration damping element is consistent with the vibration direction during multi-directional coupling test.

[0004] After the existing equipment is completed, the vibrator itself will vibrate during operation. The continuous vibration will be directly transmitted to the support through the connected base, which may cause the bolts at the connection to loosen, the support structure to fatigue and deform, and reduce the service life of the equipment. Therefore, we propose an anti-vibration coupling test support structure. Utility Model Content

The inner wall of the base has a positioning groove. A first damper is fixedly connected to the inner wall of the base. A first spring is fixedly connected to the outer wall of the first damper. A first positioning plate is fixedly connected to the outer wall of the first damper away from the base. A plurality of hollow rods are rotatably connected to the outer wall of the first positioning plate. A slider is rotatably connected to the outer wall of the hollow rod away from the first positioning plate. A positioning shaft is slidably connected to the inner wall of the hollow rod. A first connecting rod is rotatably connected to the outer wall of the positioning shaft. A limit mechanism is provided on the outer wall of the bracket.

[0007] Furthermore, a first positioning block is rotatably connected to the outer wall of the end of the first connecting rod away from the positioning shaft, a second connecting rod is rotatably connected to the outer wall of the positioning shaft, and a second positioning block is rotatably connected to the outer wall of the end of the second connecting rod away from the positioning shaft.

[0008] Furthermore, the outer wall of the vibrator is inserted into the inner wall of the positioning groove, the outer wall of the first spring is fixedly connected to the outer wall of the first positioning plate, the outer wall of the slider is slidably connected to the inner wall of the positioning groove, the outer wall of the first positioning block is fixedly connected to the inner wall of the positioning groove, and the outer wall of the second positioning block is fixedly connected to the inner wall of the positioning groove.

[0009] Furthermore, the limiting mechanism includes a motor, the outer wall of which is fixedly connected to the inner wall of the bracket, and the output end of the motor is fixedly connected to a bidirectional threaded rod via a coupling. The outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the bracket. A plurality of second positioning plates are threadedly connected to the outer wall of the bidirectional threaded rod, and a plurality of sliding rods are slidably connected to the inner wall of the second positioning plates. The outer wall of the sliding rods is fixedly connected to the outer wall of the bracket.

[0010] Furthermore, a rubber extrusion block is fixedly connected to the outer wall of the second positioning plate, a first fixing block is fixedly connected to the inner wall of the rubber extrusion block, and a plurality of first support rods are rotatably connected to the outer wall of the first fixing block.

[0011] Furthermore, a connecting shaft is rotatably connected to the outer wall of the end of the first support rod away from the first fixing block, and a second support rod is rotatably connected to the outer wall of the connecting shaft. A second fixing block is rotatably connected to the outer wall of the end of the first connecting rod away from the connecting shaft.

[0014] This utility model has the following beneficial effects: 1. This utility model incorporates a first damper and a first spring. The vibration generated by the exciter is transmitted through the first positioning plate to the first damper and the first spring connected to its rear side. Through the cooperation of the first damper and the first spring, the vibration received by the first positioning plate can be absorbed. The cooperation of the first damper and the first spring also alleviates and absorbs the vibration generated during the operation of the exciter, preventing the continuous vibration caused by the exciter itself during operation from being directly transmitted to the support through the connected base. This could lead to loose bolts at the connection point, fatigue deformation of the support structure, and reduced service life of the equipment.

[0015] 2. This utility model incorporates a bidirectional threaded rod and a rubber extrusion block. When the motor is started, it drives the bidirectional threaded rod to rotate, simultaneously pushing two second positioning plates closer together. The movement range of the two second positioning plates is limited by two identical sliding rods, thus thermally stabilizing the movement of the second positioning plates. The movement of the second positioning plates pushes the rubber extrusion block to contact both sides of the workpiece under test. The rotation of the bidirectional threaded rod pushes the two second positioning plates closer together, and pushes the rubber extrusion block to clamp the workpiece under test. This prevents the workpiece from colliding with the support section and causing surface damage due to lateral swaying or even momentary displacement during testing.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, this utility model is a vibration coupling test support structure, including a base 1, a support 101 fixedly connected to the top outer wall of the base 1, a support plate 102 fixedly connected to the outer wall of the support 101, and a plurality of positioning bolt holes 103 opened on the inner wall of the support plate 102. By opening a plurality of positioning bolt holes 103 on the support plate 102, the test piece can be easily fixed to the surface of the support plate 102 by positioning bolts. A shock-absorbing mechanism 2 is provided on the inner wall of the base 1. The shock-absorbing mechanism 2 includes a vibrator 201. The outer wall of the vibrator 201 is inserted into the inner wall of the base 1. A positioning groove 202 is provided on the inner wall of the base 1. The vibrator 201 can be completely fixed inside the base 1 through the positioning groove 202, preventing its lateral and longitudinal movement. A first damper 203 is fixedly connected to the inner wall of the base 1. A first spring 204 is fixedly connected to the outer wall of the first damper 203. A first positioning plate 205 is fixedly connected to the outer wall of the first damper 203 away from the base 1. The interaction between the first damper 203 and the first spring 204 can alleviate the shock. It absorbs the vibration received by the first positioning plate 205, stabilizes the position of the vibrator 201 inside the positioning groove 202, and prevents displacement. Several hollow rods 206 are rotatably connected to the outer wall of the first positioning plate 205. A slider 207 is rotatably connected to the outer wall of the hollow rod 206 away from the first positioning plate 205. When the first positioning plate 205 vibrates, it pushes the hollow rods 206 to rotate around the first positioning plate 205, while simultaneously pushing the slider 207 to move. Thus, the connection of the hollow rods 206 shares the vibration received by the first positioning plate 205, stabilizing its movement. A positioning shaft 2 is slidably connected to the inner wall of the hollow rods 206. 08. A first connecting rod 209 is rotatably connected to the outer wall of the positioning shaft 208. A limit mechanism 3 is provided on the outer wall of the bracket 101. A first positioning block 210 is rotatably connected to the outer wall of the first connecting rod 209 away from the positioning shaft 208. When the hollow rod 206 rotates, it will drive the positioning shaft 208 to move and push the first connecting rod 209 to rotate around the inside of the second positioning block 212. Thus, the pressure and vibration of the hollow rod 206 are shared by the connection of the first connecting rod 209, increasing the support strength of the hollow rod 206. A second connecting rod 211 is rotatably connected to the outer wall of the positioning shaft 208. The second connecting rod 211 is away from the positioning shaft 208. A second positioning block 212 is rotatably connected to the outer wall of one end of the shaft 208. During the movement of the positioning shaft 208, the second connecting rod 211 will be pulled to rotate around the second positioning block 212, thereby using the second connecting rod 211 to share the pressure and vibration of the hollow rod 206. The outer wall of the vibrator 201 is inserted into the inner wall of the positioning groove 202. The outer wall of the first spring 204 is fixedly connected to the outer wall of the first positioning plate 205. The outer wall of the slider 207 is slidably connected to the inner wall of the positioning groove 202. The outer wall of the first positioning block 210 is fixedly connected to the inner wall of the positioning groove 202. The outer wall of the second positioning block 212 is fixedly connected to the inner wall of the positioning groove 202.

[0022] The limiting mechanism 3 includes a motor 301. The motor 301 is activated, and its outer wall is fixedly connected to the inner wall of the bracket 101. The output end of the motor 301 is fixedly connected to a bidirectional threaded rod 302 via a coupling. The motor 301 drives the bidirectional threaded rod 302 to rotate inside the bracket 101. The outer wall of the bidirectional threaded rod 302 is rotatably connected to the inner wall of the bracket 101. Several second positioning plates 303 are threadedly connected to the outer wall of the bidirectional threaded rod 302, and several sliding rods 304 are slidably connected to the inner wall of the second positioning plates 303. The rotation of the bidirectional threaded rod 302 pushes two... As the second positioning plates 303 approach each other, the movement range of the second positioning plates 303 is limited by two sliding rods 304, thereby stabilizing the movement of the second positioning plates 303 using the sliding rods 304. The outer wall of the sliding rods 304 is fixedly connected to the outer wall of the bracket 101. A rubber extrusion block 305 is fixedly connected to the outer wall of the second positioning plate 303. The movement of the second positioning plate 303 pushes the rubber extrusion block 305 to move towards both sides of the test piece. A first fixing block 306 is fixedly connected to the inner wall of the rubber extrusion block 305. Several first support rods 307 are rotatably connected to the outer wall of the first fixing block 306.

[0023] The outer wall of the first support rod 307, away from the first fixed block 306, is rotatably connected to a connecting shaft 308. The movement of the first fixed block 306 pushes the first support rod 307 to rotate around the outside of the first fixed block 306, simultaneously pushing the connecting shaft 308 outward. The outer wall of the connecting shaft 308 is rotatably connected to a second support rod 309. The outer wall of the first connecting rod 309, away from the connecting shaft 308, is rotatably connected to a second fixed block 310. The movement of the connecting shaft 308 pulls the second support rod 309 to rotate around the outside of the second fixed block 310. Thus, the connection and rotation of the second support rod 309 stabilizes the movement of the connecting shaft 308, increasing the internal support force of the rubber extrusion block 305. The outer wall of the second fixed block 310 is fixedly connected to the inner wall of the rubber extrusion block 305. The outer wall of the first support rod 307 is rotatably connected to a third support rod 311. A third fixed block 312 is rotatably connected to the outer wall of the end of 311 away from the first support rod 307. The rotation of the first support rod 307 pushes the third support rod 311 to rotate around the third fixed block 312. The connection of the third support rod 311 increases the support range of the first support rod 307 for the rubber extrusion block 305. A connecting block 313 is rotatably connected to the outer wall of the connecting shaft 308. A second damper 314 is fixedly connected to the outer wall of the connecting block 313. A second spring 315 is fixedly connected to the outer wall of the second damper 314. When the two connecting shafts 308 move, they will drive the two connecting blocks 313 to move away from each other, and the two connecting blocks 313 will pull the second damper 314 and the second spring 315. Thus, the cooperation of the second damper 314 and the second spring 315 will alleviate and absorb the pressure generated when the connecting block 313 moves, and reduce the vibration of the rubber extrusion block 305.

[0024] One specific application of this embodiment is: When the operator needs to use the equipment, the workpiece to be tested is placed on the surface of the support plate 102, and the positioning holes of the workpiece are aligned with the multiple positioning bolt holes 103 on the support plate 102. The workpiece is then fixed to the surface of the support plate 102 using bolts. The motor 301 is then started, causing the bidirectional threaded rod 302 to rotate while simultaneously pushing the two second positioning plates 303 closer together. The movement range of the two second positioning plates 303 is limited by two identical sliding rods 304, thus stabilizing the movement of the second positioning plates 303. The movement of the second positioning plates 303 pushes the rubber extrusion block 305 to contact both sides of the workpiece, compressing the rubber extrusion block 305 and causing it to deform. When the rubber extrusion block 305 deforms, it pushes... The first fixing block 306 causes multiple first support rods 307 to rotate, and the rotation of the first support rods 307 pushes the two connecting shafts 308 away from each other. The movement of the connecting shafts 308 pulls the second support rod 309 to rotate around the second fixing block 310. Thus, the connection between the first support rods 307 and the second support rods 309 distributes the pressure and vibration on the rubber extrusion block 305, while increasing the internal support force of the rubber extrusion block 305. During the rotation of the first support rods 307, the third support rod 311 is pushed to rotate around the connecting block 313. Thus, the support force generated by the first support rods 307 is evenly distributed inside the rubber extrusion block 305 by the connection of the third fixing block 312. The contact range between the stable rubber extrusion block 305 and the test piece is maintained. When the two connecting shafts 308 move away from each other, the two connecting blocks 313 will move away from each other, causing the two connecting blocks 313 to pull the second damper 314 and the second spring 315 in the middle. Through the cooperation of the second damper 314 and the second spring 315, the pressure of the connecting blocks 313 during movement and the vibration of the rubber extrusion block 305 can be relieved and absorbed. Then, the vibrator 201 is inserted into the positioning groove 202 opened inside the base 1, and the two sides of the vibrator 201 will contact the first positioning plate 205. After the vibrator 201 is started, it will generate a certain vibration, and the vibration generated by the vibrator 201 will be transmitted to the rear through the first positioning plate 205. The first damper 203 and the first spring 204, connected sideways, absorb the vibration of the first positioning plate 205 through their mutual cooperation, thereby stabilizing the position of the vibrator 201 inside the positioning groove 202. When the first positioning plate 205 vibrates, it pushes multiple hollow rods 206 to rotate around the first positioning plate 205, and uses the hollow rods 206 to push the slider 207 to move along the inner wall of the positioning groove 202. Thus, the rotation of the hollow rods 206 and the connection share the vibration borne by the first positioning plate 205. During the rotation of the hollow rods 206, the positioning shaft 208 moves and pushes the first connecting rod 209 to rotate around the first positioning block 210.Furthermore, when the positioning shaft 208 moves, it also pulls the second connecting rod 211, causing it to rotate around the second positioning block 212. This, through the connection between the first connecting rod 209 and the second connecting rod 211, shares the vibration experienced by the hollow rod 206 and limits the rotation range of the hollow rod 206.
