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

[0018] Example 1

[0019] See Figs. 1-2A multi-axis synchronous vibration test bench support includes a support body 1, a rotating camera assembly 2, and a limiting connection assembly 3. The rotating camera assembly 2 is installed inside the support body 1, and the limiting connection assembly 3 is installed below the rotating camera assembly 2. First cylinders 4 are symmetrically embedded on both sides of the support body 1. One end of the telescopic rod of the first cylinder 4 is fixedly connected to a clamping frame 5. Test shafts 6 are symmetrically installed inside the support body 1. When a part is placed between the clamping frames 5, the first cylinder 4 is activated to clamp and fix the part with the clamping frames 5, and then the test shaft 6 contacts the part, facilitating the testing of the part through the test bench.

[0020] The rotating camera assembly 2 includes a support plate 201, a motor 202, a gear 203, an annular guide rail 204, a slip ring 205, an external gear ring 206, a first connecting plate 207, a compression ring 208, a second connecting plate 209, a rotating groove 2010, a rotating rod 2011, a first spring 2012, and a camera probe 2013. An annular guide rail 204 is welded to the inner wall of the bottom end of the support body 1. A slip ring 205 is slidably connected inside the annular guide rail 204. An external gear ring 206 is welded to the outer wall of the bottom end of the slip ring 205. A gear 203 is meshed on one side of the outer wall of the external gear ring 206. A support plate 201 is welded to one side of the outer wall of the support body 1. A motor 202 is embedded in the bottom end of the support plate 201, and the bottom end of the output shaft of the motor 202 is fixed to the outer wall of the gear 203. Second connecting plates 209 are distributed and welded to the outer wall of the bottom end of the external gear ring 206. A rotating groove 2010 is provided at the bottom of 09. A rotating rod 2011 is rotatably connected to the inner walls of both sides of the rotating groove 2010. A camera probe 2013 is installed on the rotating rod 2011. A first spring 2012 is symmetrically fixed to the camera probe 2013, and the other end of the first spring 2012 is fixed to the inner wall of the rotating groove 2010. A compression ring 208 is installed on one side of the camera probe 2013. A first connecting plate 207 is symmetrically fixed to the outer wall of the top of the compression ring 208, and the top of the first connecting plate 207 is fixed to the inner wall of the annular guide rail 204. The first spring 2012 is sleeved on the outer wall of the rotating rod 2011. The first spring 2012 is a torsion spring. When the camera probe 2013 is separated from the compression ring 208, the torsion action of the first spring 2012 facilitates the reset and adjustment of the camera angle of the camera probe 2013.

[0021] Working principle: When testing a part, the part is first placed between the clamping frames 5. The first cylinder 4 is activated to clamp and fix the part in place. Then, the test shaft 6 contacts the part, and the part is tested on the test bench. During the test, the camera probe 2013 is activated to record the test process. Then, the motor 202 on the support plate 201 is activated to rotate the gear 203, causing the slip ring 205 on the external gear ring 206 to rotate 90 degrees back and forth along the annular guide rail 204. This causes the second connecting plate 209 to drive the camera probe 2013 to rotate 90 degrees back and forth. The camera probe 2013 is squeezed by the squeezing ring 208 on the first connecting plate 207, causing the rotating rod 2011 on the camera probe 2013 to rotate along the rotating groove 2010. When the camera probe 2013 separates from the squeezing ring 208, the camera angle of the camera probe 2013 is reset and adjusted by the torsion action of the first spring 2012, thus recording the entire test process. This allows for video recording of the test process of the parts, and when defects occur in the parts, the influencing factors can be identified, improving the test results.

[0022] Example 2

[0023] See Figs. 2-3 The limiting connection assembly 3 includes a connecting frame 301, a second cylinder 302, a semi-circular pressing block 303, a fixing plate 304, a guide hole 305, a moving plate 306, an insert plate 307, a guide rod 308, an arc plate 309, and a second spring 3010. The connecting frame 301 is welded inside the main body 1. The second cylinder 302 is embedded in the connecting frame 301. The two ends of the telescopic rod of the second cylinder 302 are fixedly connected to the semi-circular pressing block 303. Fixing plates 304 are welded to the outer walls of both sides of the connecting frame 301. Guide holes 305 are opened on the fixing plates 304. A guide rod 308 is sleeved inside the guide holes 305. One end of the guide rod 308 is fixedly connected to the moving plate 306. A plate 307 is welded to one side of the outer wall of the 306. An arc plate 309 is fixed to the other end of the guide rod 308. One side of the arc plate 309 is attached to the outer wall of the semi-circular extrusion block 303. A second spring 3010 is fixed to the other side of the outer wall of the arc plate 309. The other end of the second spring 3010 is fixed to the outer wall of the fixing plate 304. The second spring 3010 is sleeved on the outer wall of the guide rod 308. There are four second springs 3010. When the semi-circular extrusion block 303 is reset, the guide rod 308 on the moving plate 306 is reset along the guide hole 305 on the fixing plate 304 under the action of the second spring 3010.

[0024] First, the support body 1 is installed inside the vibration test bench. Then, the second cylinder 302 on the connecting frame 301 is activated, causing the semi-circular pressing block 303 to move. The arc-shaped portion of the semi-circular pressing block 303 presses against the arc plate 309, causing the guide rod 308 on the moving plate 306 to move along the guide hole 305 on the fixed plate 304. This allows the distributed insert plates 307 to be inserted into the vibration test bench, fixing most of the support body 1 in position. This prevents vibration stress from affecting the support body 1 during component vibration. When the main body 1 of the support needs to be disassembled, the second cylinder 302 is activated to reset the semi-circular pressing block 303. Then, under the action of the second spring 3010, the guide rod 308 on the moving plate 306 is reset along the guide hole 305 on the fixed plate 304, so that the insert plate 307 is separated from the vibration test bench, thereby enabling the main body 1 of the support to be quickly disassembled. When the equipment is installed, it can limit and fix various parts of the equipment. When the parts are tested, it reduces the large shaking of the equipment, avoids affecting the test of the parts, and improves the use effect of the equipment.
