Description

Technical Field

[0001] The utility model relates to the technical field of engine testing, in particular to an engine waterproof testing device. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. In the process of engine production or maintenance, engine waterproof testing is one of the important links, which is of great significance for ensuring the performance and life of the engine. However, when performing a waterproof test on the engine, the engine is often manually placed in a water tank and the entire engine is sunk into the water. Then, the engine surface is observed to see whether bubbles are generated to determine whether the engine is leaking. However, when the engine is placed manually, due to the heavy weight of the engine as a whole, it is difficult to put in or take out the engine, which can easily cause personal injury and engine damage. Therefore, we propose an engine waterproof testing device to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, an embodiment of the utility model proposes an engine waterproof testing device, including a storage box 1, a conveying mechanism 2 is installed on the outer side of the storage box 1, the conveying mechanism 2 includes a support frame 201, a slider 206 is movably installed on the lower end of the inner part of the support frame 201, the slider 206 is parallel to the storage box 1 up and down, a cylinder 207 is installed on the front and rear ends of the slider 206, a rotating block 210 is movably installed on the lower end of the inner part of the support frame 201, the output end of the cylinder 207 is movably connected to the rotating block 210, a placement plate 214 is installed on the lower end of the rotating block 210, the rotating block 210 is parallel to the placement plate 214 and the storage box 1, and the rotating block 210 and the placement plate 214 are both movably installed inside the storage box 1.

[0022] like Figure 4 and Figure 5As shown, in another embodiment of the utility model, the storage box 1 is set to be transparent, and the two ends of the inner lower surface of the support frame 201 are fixedly installed with fixed blocks 202 respectively, and a threaded rod 203 is movably installed between the fixed blocks 202. A motor No. 1 204 is installed on one side of the support frame 201, and the motor No. 1 204 is connected to the threaded rod 203. The rod body of the threaded rod 203 is installed in the inside of the slider 206 through a thread, and the front and rear ends of the interior of the fixed block 202 are fixedly installed with guide rods 205 respectively, and the rod bodies of the guide rods 205 are movably installed in the inside of the slider 206, and the lower end of the interior of the support frame 201 is movably installed with a fixed plate 208 The fixed plate 208 is fixedly connected to the output end of the cylinder 207, and a No. 2 motor 209 is installed on the upper end of the fixed plate 208. The output end of the No. 2 motor 209 movably passes through the interior of the fixed plate 208 and is connected to the rotating block 210. The lower end of the output end of the cylinder 207 is fixedly installed with a limit plate 211. The upper surface of the rotating block 210 is provided with an annular groove 212, and the limit plates 211 are respectively snap-fitted and installed inside the annular groove 212. The four corners of the lower surface of the rotating block 210 are fixedly installed with connecting blocks 213. The lower end of the connecting block 213 is fixedly connected to the placement plate 214, and a plurality of protrusions 215 are installed on the upper surface of the placement plate 214.

[0023] The user places the engine on the surface of the placement plate 214, and then the cylinder 207 can pull the rotating block 210 and the placement plate 214 upwards through the cooperation of the limit plate 211 and the annular slide groove 212. After the height of the placement plate 214 and the engine is higher than the storage box 1, the No. 1 motor 204 controls the threaded rod 203 to rotate, so that the threaded rod 203 moves through the threaded control slider 206 and the placement plate 214, and moves the placement plate 214 and the engine to the upper end of the storage box 1. Then the cylinder 207 controls the placement plate 214 and the engine to slowly enter the interior of the storage box 1, so that the engine is immersed in water, and then the user The engine can be observed to see if there are bubbles seeping out of the engine surface. At the same time, the second motor 209 can drive the rotating block 210 and the placement plate 214 to rotate, so that the placement plate 214 drives the engine to rotate slowly inside the storage box 1, so that the engine follows the placement plate 214 to rotate, and the position angle of the engine is adjusted, which is more convenient for users to observe. Finally, after the engine waterproof test is completed, the user can control the engine to follow the placement plate 214 to leave the storage box 1 through the cylinder 207, and then adjust the position of the engine through the cooperation of the threaded rod 203 and the slider 206;

[0024] When the rotating block 210 rotates under the control of the second motor 209, the limiting plate 211 cooperates with the annular slide groove 212, which will not hinder the rotation of the rotating block 210, and can also stably support the rotating block 210;

[0025] The protrusion 215 is used to isolate the placement plate 214 from the engine, leaving a gap between the engine and the placement plate 214, so that the user can observe the bottom of the engine to see if there is any leakage problem;

[0026] By making the storage box 1 transparent, it is convenient for the user to observe the surface of the engine. If penetration occurs on the surface of the engine, the user can more directly and clearly understand where the penetration occurs, making it easier for the user to perform maintenance work on the engine later.

[0027] The working principle of this engine waterproof testing device:

[0028] When in use, the user first places the engine on the surface of the placement plate 214, and then the cylinder 207 can pull the rotating block 210 and the placement plate 214 upwards through the cooperation of the limit plate 211 and the annular slide groove 212. After the height of the placement plate 214 and the engine is higher than the storage box 1, the first motor 204 controls the threaded rod 203 to rotate, so that the threaded rod 203 moves through the threaded control slider 206 and the placement plate 214, and moves the placement plate 214 and the engine to the upper end of the storage box 1. Then, the cylinder 207 controls the placement plate 214 and the engine to slowly enter the interior of the storage box 1, allowing the engine to be immersed in water, and then The user can observe the engine to check whether there are bubbles seeping out of the surface of the engine. At the same time, the No. 2 motor 209 can drive the rotating block 210 and the placement plate 214 to rotate, so that the placement plate 214 drives the engine to rotate slowly inside the storage box 1, so that the engine follows the placement plate 214 to rotate, and the position angle of the engine is adjusted, which is more convenient for the user to observe. Finally, after the engine waterproof test is completed, the user can control the engine to follow the placement plate 214 to leave the interior of the storage box 1 through the cylinder 207, and then adjust the position of the engine through the cooperation of the threaded rod 203 and the slider 206.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
