[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Reference Figure 1-4, a car motor sealing detection device, including a bottom plate 1, a box body 2 is fixedly installed on the top side of the bottom plate 1, the bottom inner wall of the box body 2 and the top side of the bottom plate 1 are fixedly installed with the same inclined block 10, the top side of the inclined block 10 is inclined, a top plate 12 is provided above the inclined block 10, a long groove is opened on the top side of the top plate 12, a clamping assembly is provided in the long groove, a rotating motor 17 is fixedly installed on one side of the box body 2, the output end of the rotating motor 17 rotates through the box body 2 and is rotatably connected to one side of the inner wall of the box body 2, two winding wheels 18 are fixedly sleeved on the outer side of the output end of the rotating motor 17, ropes 19 are fixedly wound around the two winding wheels 18, and the other ends of the two ropes 19 are fixedly connected to one side of the top plate 12. A vacuum component and a detection component are respectively provided on one side and the top side of the body 2. The two winding wheels 18 on the outside of the output end are driven to rotate counterclockwise by the rotating motor 17. When the two winding wheels 18 rotate counterclockwise, the ropes 19 are reeled in, so that the top plate 12 is pulled slowly toward the box body 2 by the two ropes 19, thereby preventing the motor from falling off and being difficult to place when it is placed in the box body 2. After the inspection is completed, the electric push rod 22 is started to drive the sealing plate 20 to move upward, and then the rotating motor 17 is started to rotate counterclockwise. Because the top side of the inclined block 10 is inclined, when the rope 19 is not in a tensioned state, the top plate 12 will slowly move out of the box body 2 through the two guide blocks 11.
[0023] Specifically, the clamping assembly includes a top plate 12 on one side of which a threaded motor 13 is fixedly installed. The output end of the threaded motor 13 rotates through the top plate 12 and is fixedly installed with a bidirectional screw 14. The other end of the bidirectional screw 14 is rotatably connected to the inner wall of one side of the long groove. Two sliders 15 are slidably installed on the outer side of the bidirectional screw 14. The top sides of the two sliders 15 are fixedly installed with a clamping plate 16. The sides of the two clamping plates 16 close to each other are fixedly installed with a protective pad. When the motor is placed on the top plate 12, the bidirectional screw 14 is driven to rotate clockwise by the operation of the threaded motor 13, so that the two sliders 15 The two clamps 16 are driven to approach each other, so that the two clamps 16 complete the clamping of both sides of the motor, and because the sides of the two clamps 16 that are close to each other are provided with protective pads, the protective pads can protect both sides of the motor from wear, and because the distance between the two clamps 16 is adjusted by the threaded motor 13, motors of different sizes can be clamped, and because the motor is tightly clamped by the two clamps 16 during the sealing test, it can avoid the motor from shaking during the sealing test, thereby making the sealing test data more accurate.
[0024] Specifically, the vacuum component includes a side panel 3 fixedly installed on one side of the box body 2, a vacuum pump 4 fixedly installed on the top side of the side panel 3, an exhaust pipe 5 and an exhaust pipe 6 fixedly installed on both sides of the vacuum pump 4, and the other end of the exhaust pipe 5 extends into the box body 2. The detection component includes an inner wall of one side and a top side of the box body 2, respectively provided with an air pressure sensor 8 and a barometer 7, a controller 9 fixedly installed on the top side of the box body 2, the controller 9 and the air pressure sensor 8 are electrically connected, and the operation of the vacuum pump 4 drives the exhaust pipe 5 to extract the air in the box body 2, thereby forming a vacuum state in the box body 2, thereby avoiding the influence of the detection environment on the detection results. When the motor leaks, the pointer of the barometer 7 rises, and the air pressure sensor 8 transmits the data to the controller 9 in real time for the staff to observe, thereby greatly improving the detection efficiency of the motor sealing of the device.
[0025] The top side of the inclined block 10 is provided with two guide grooves, and guide blocks 11 are slidably installed in the two guide grooves. The top sides of the two guide blocks 11 are fixedly connected to the bottom side of the top plate 12. A sealing groove is provided on the top side of the inclined block 10, and a plug hole is provided on the top side of the box body 2, which is connected to the sealing groove, and a sealing plate 20 is inserted in the plug hole. A connecting plate 21 is fixedly installed on the top side of the sealing plate 20, and an electric push rod 22 is fixedly installed on the inner wall of the top side of the box body 2. The output end of the electric push rod 22 passes through the box body 2 and is fixedly connected to the bottom side of the connecting plate 21. Through the two guide blocks 11, the two guide blocks 11 can provide stable guiding and limiting effects during the movement of the top plate 12. When the top plate 12 moves into the box body 2, the sealing plate 20 can be driven downward by the operation of the electric push rod 22. When the bottom side of the sealing plate 20 is inserted into the sealing groove opened by the inclined block 10, the overall sealing of the box body 2 can be achieved, and then the sealing test can be carried out.
[0026] Specifically, a baffle 23 is fixedly installed on one side of the top plate 12, and the baffle 23 is located on one side of the two clamping plates 16. Through the baffle 23, when the motor is placed on the top plate 12, because the inclined block 10 is inclined, the motor will move toward the baffle 23 due to inertia, and at this time the baffle 23 can play a role in supporting the motor.
[0027] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.
[0028] When in use: the staff places the inflated motor on the top plate 12, and then starts the threaded motor 13 to drive the bidirectional screw 14 to rotate clockwise, so that the two sliders 15 drive the two clamping plates 16 to approach each other, and then the two clamping plates 16 complete the clamping of the two sides of the motor, and because the two clamping plates 16 are provided with protective pads on the side close to each other, the protective pads can protect the two sides of the motor from wear, and because the distance between the two clamping plates 16 is adjusted by the threaded motor 13, motors of different sizes can be clamped. After clamping is completed, the two winding wheels 18 on the outer side of the output end are driven to rotate counterclockwise by the rotating motor 17. When the two winding wheels 18 rotate counterclockwise, the ropes 19 are reeled in, so that the top plate 12 slowly moves toward the box body 2 under the pull of the two ropes 19, thereby preventing the motor from falling off and being difficult to place when it is placed in the box body 2. When it moves into the box body 2, the electric push rod 22 drives the connecting plate 21 to move downward, and the connecting plate 21 During the downward movement, the sealing plate 20 will be driven downward synchronously. When the bottom side of the sealing plate 20 is inserted into the sealing groove opened by the inclined block 10, the overall sealing of the box body 2 can be completed. Then the vacuum pump 4 is operated to drive the exhaust pipe 5 to extract the air in the box body 2, thereby forming a vacuum state in the box body 2, thereby avoiding the influence of the detection environment on the detection results. When the motor leaks, the pointer of the barometer 7 rises, and the air pressure sensor 8 transmits the data to the controller 9 in real time for observation by the staff, thereby greatly improving the detection efficiency of the motor sealing of the device. After the detection is completed, the electric push rod 22 is started to drive the sealing plate 20 to move upward, and then the rotating motor 17 is started to rotate counterclockwise. Because the top side of the inclined block 10 is inclined, when the rope 19 is not in a tensioned state, the top plate 12 will slowly move out of the box body 2 through the two guide blocks 11, and then the threaded motor 13 is started to drive the bidirectional screw 14 to rotate counterclockwise, so that the two clamps 16 stop clamping the motor.
