[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: an engineering test bench, including: a support plate 1, legs 101 are installed at the four ends of the bottom of the support plate 1, three first fixing plates 102 are installed on both sides of the top of the support plate 1, the six first fixing plates 102 are evenly divided into three groups, shock absorption devices 2 are arranged inside the three groups of first fixing plates 102, the tops of the three shock absorption devices 2 are provided with a fixed box 3, and a rotating device 4 is arranged inside the fixed box 3.
[0024] Specifically: The shock absorber 2 is used to shock-absorb the fixed box 3 to make the surface of the engineering test platform 405 reach a stable effect, and then the rotating device 4 is used to rotate the engineering test platform 405 to prevent the staff from repeatedly moving and reducing work efficiency.
[0025] In one embodiment, two limiting rods 302 are installed on both sides of the bottom of the fixed box 3. Limiting rings 303 are installed at one ends of the four limiting rods 302. A plurality of universal beads 301 are equidistantly and movably embedded on both sides of the top of the fixed box 3. A connecting block 304 is installed at the bottom of the inner cavity of the fixed box 3. A second fixing plate 305 is installed at the bottom of the inner cavity of the fixed box 3. Two limiting holes 104 are opened on both sides of the bottom of the support plate 1. Guide holes 103 are opened at the centers of the four limiting holes 104.
[0026] Specifically: The limiting rods 302 and the limiting rings 303 move and are limited inside the guide holes 103 and the limiting holes 104, and then the universal beads 301 support and assist in rotating the engineering test platform 405, playing a role in limiting movement and assisting in supporting rotation.
[0027] In one embodiment, the shock absorber 2 includes two dampers 201. Moving blocks 203 are installed at one ends of the two dampers 201. Springs 202 are movably sleeved on the surfaces of the two dampers 201. Fixed rods 204 are movably embedded at both ends of the two moving blocks 203. First U-shaped plates 205 are installed at the tops of the two moving blocks 203. Connecting rods 206 are movably connected inside the two first U-shaped plates 205. One ends of the two connecting rods 206 are movably connected to a second U-shaped plate 207.
[0028] Specifically: The movement of the moving blocks 203 squeezes or stretches the dampers 201 and the springs 202 to reduce the vibration of the engineering test platform 405, playing a role in shock absorption.
[0029] In one embodiment, the other ends of the two dampers 201 are installed on both sides of the opposite surfaces of one group of first fixing plates 102. Both ends of the two fixed rods 204 are installed on both sides of the opposite surfaces of one group of first fixing plates 102. The top of the second U-shaped plate 207 is installed in the middle of the bottom of the fixed box 3.
[0030] Specifically: The first fixing plates 102 and the fixed box 3 fix and connect the dampers 201, the fixed rods 204 and the second U-shaped plate 207, playing a role in connection and fixation.
[0031] In one embodiment, the rotating device 4 includes a forward and reverse motor 401. The output end of the forward and reverse motor 401 is fixedly connected to a transmission shaft 402. A bevel gear 403 is fixedly sleeved on the surface of the transmission shaft 402. A bevel gear ring 404 is meshed and connected to the surface of the bevel gear 403. An engineering test platform 405 is installed on the top of the bevel gear ring 404. A rotating shaft 406 is installed at the center of the bottom of the engineering test platform 405.
[0032] Specifically: While the forward and reverse motor 401 drives the bevel gear 403 to rotate, it also drives the engineering test platform 405 to rotate, playing a role in rotation.
[0033] In one embodiment, the surface of the forward and reverse motor 401 is installed on the top of the connecting block 304. One end of the transmission shaft 402 is installed on one side of the second fixing plate 305 through a bearing. The bottom end of the rotating shaft 406 is installed at the center of the inner cavity bottom of the fixed box 3 through a bearing. The bottom of the engineering test platform 405 is in close contact with the surfaces of a plurality of universal beads 301.
[0034] Specifically: The forward and reverse motor 401, the transmission shaft 402, and the rotating shaft 406 are connected and fixed through the connecting block 304, the second fixing plate 305, and the fixed box 3. Then, the universal beads 301 are used to assist the rotation of the engineering test platform 405 and support it, playing a role in fixed connection and rotational support.
[0035] Working principle: Electrically connect the forward and reverse motor 401 to an external controller. Then, place the entire device on a horizontal ground and support it through the support legs 101. Place the item to be tested on the top of the engineering test platform 405, and let the staff conduct engineering tests on the item. When the device vibrates or is vibrated by external factors, the two movable blocks 203 move along the surface of the fixed rod 204 in opposite or relative directions, pulling the connecting rod 206 and the second U-shaped plate 207. Then, the damper 201 and the spring 202 are used to reduce the amplitude of the up and down movement of the fixed box 3, avoiding damage to the item during the engineering test of the item and inaccurate test data due to vibration. During the process of conducting engineering tests on the item to be tested, it is inconvenient to operate some parts, and rotation is required. When the external controller starts the forward and reverse motor 401 to drive the transmission shaft 402 and the bevel gear 403 to rotate, it also drives the bevel gear ring 404 and the engineering test platform 405 to rotate around the rotating shaft 406. Then, a plurality of universal beads 301 support the bottom of the engineering test platform 405 and assist in rotation, also avoiding the inconvenience that occurs when operating and testing some parts during the process of conducting engineering tests on the item to be tested, which requires the staff to move around the device repeatedly, resulting in a decrease in work efficiency and an increase in working time.
[0036] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
