[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] A detection device for the production of a water pump housing, including a detection component. The detection component includes an installation cavity 6. Two slide plates 7 are symmetrically arranged in the installation cavity 6. The two slide plates 7 can move towards or away from each other. An air pump 11 is fixedly connected to the left side of the installation cavity 6. The air pump 11 is connected to a spring tube 12. An air hole 13 communicating with the spring tube 12 is opened on the left slide plate 7. The air hole 13 is docked with the air inlet end of the water pump housing. An air chamber 14 is also opened on the left slide plate 7. The spring tube 12 is communicated with the air chamber 14. The air holes 13 are arranged at equal intervals and the air holes 13 are communicated with the air chamber 14.

[0026] By adopting the above design, after the air hole 13 is docked with the air inlet end of the water pump housing and the device is immersed in water, the air pump 11 can be started, so that the gas enters the air chamber 14 through the spring tube 12 and is discharged through the air hole 13. When the gas is discharged from the air hole 13, it will enter the water pump housing. If there is a crack in the water pump housing, the gas will continuously gush out from the crack, and then form bubbles in the water. At this time, the staff can judge the airtightness of the water pump housing and the crack position by observing whether there are bubbles and the starting position of the bubbles.

[0027] It further includes a driving component. The driving component includes a clamping motor 8 fixedly connected to the right side of the installation cavity 6. The output shaft of the clamping motor 8 is fixedly connected to a bidirectional screw 9. The bidirectional screw 9 is rotatably connected in the installation cavity 6. A T-shaped chute is opened in the installation cavity 6. The upper end of the slide plate 7 is a T-shaped plate adapted to the chute. Threaded through holes are opened on the slide plate 7. The two slide plates 7 are threadedly engaged with both sides of the bidirectional screw 9 through the threaded through holes.

[0028] It further includes a suspension 2, a liquid storage tank 1 is arranged below the suspension 2, a lifting component is installed on the top surface of the suspension 2, the lifting component includes a lifting motor 3 fixedly connected to the top surface of the suspension 2, the output shaft of the lifting motor 3 is fixedly connected with a winding roller 4, the winding roller 4 is connected with a cable 5, a through hole is opened on the top surface of the suspension 2, the cable 5 passes through the through hole and is connected with the top surface of the installation cavity 6, the winding roller 4 is divided into upper and lower rolls, both of which are connected with the cable 5, and the two cables 5 are respectively fixedly connected with both ends of the top surface of the installation cavity 6.

[0029] By setting the driving component, the clamping motor 8 can be started to drive the bidirectional screw 9 to rotate. Since the threaded through holes on the slide plates 7 are meshed with the two-side threads of the bidirectional screw 9, the two slide plates 7 will move towards or away from each other. When the slide plates 7 move towards each other, the sealing gaskets 10 contact and press tightly at the connecting ports at both ends of the water pump housing, so as to fix the position of the water pump housing. After the clamping is completed, the lifting motor 3 can be started to drive the winding roller 4 to rotate and release the cable 5, so that the installation cavity 6 descends into the liquid storage tank 1 until the water pump housing is immersed in water, and then the lifting motor 3 can be turned off.

[0030] By setting the lifting component, the water pump housing can be lifted and placed between the two slide plates 7, and then the lifting motor 3 is started to drive the winding roller 4 to rotate to take in and release the cable 5, so as to lift and lower both ends of the installation cavity 6 connected with the cable 5, and ensure the stability of the installation cavity 6 during the lifting process without adding a driving source.

[0031] Furthermore, sealing gaskets 10 are arranged on one side of the two slide plates 7 close to the left and right central axes of the installation cavity 6, and the sealing gasket 10 on the left slide plate 7 is provided with a connection hole adapted to the air hole 13.

[0032] By setting the sealing gasket 10, the airtightness at the connection between the slide plate 7 and the water pump housing can be higher, and the situation that bubbles are generated due to insufficient airtightness at the connection and affect the detection result can be prevented.

[0033] In addition, a waterproof lamp strip 101 is installed in the inner wall of the liquid storage tank 1. There are four waterproof lamp strips 101, which are installed in the middle sections of the four inner walls of the liquid storage tank 1. Both ends of the suspension 2 are fixedly installed on the left and right sides of the top surface of the liquid storage tank 1.

[0034] By setting the waterproof lamp strip 101, even in a relatively dim occasion, the waterproof lamp strip 101 can be turned on to provide sufficient light for the inside of the liquid storage tank 1, making it more convenient for the staff to observe the bubbles.

[0035] Optionally, the side surface of the liquid storage tank 1 can adopt transparent materials such as glass or acrylic boards, so that the staff can observe the bottom end of the water pump housing from the outside.

[0036] Working principle:

[0037] In the initial state, the lifting motor 3 is in a stopped state, the installation cavity 6 is above the liquid storage tank 1, the clamping motor 8 is also in a stopped state, the bidirectional screw 9 is stationary, the two sliding plates 7 are respectively located on the left and right sides of the installation cavity 6, and the air pump 11 is not started.

[0038] When in use, lift the water pump housing and place it between the two sliding plates 7, and then start the clamping motor 8 to drive the bidirectional screw 9 to rotate. Since the threaded through holes on the sliding plates 7 are engaged with the threads on both sides of the bidirectional screw 9, the two sliding plates 7 are driven to move towards each other. When the sliding plates 7 move towards each other, the sealing gasket 10 contacts and presses against the two end connection ports of the water pump housing, thereby fixing the position of the water pump housing. After the clamping is completed, the lifting motor 3 can be started to drive the winding roller 4 to rotate and release the cable 5, so that the installation cavity 6 descends into the liquid storage tank 1 until the water pump housing is immersed in water, and then the lifting motor 3 can be turned off.

[0039] After the immersion is completed, the air pump 11 can be started to make the gas enter the air chamber 14 through the bellows 12 and discharge through the air holes 13. When the gas discharges from the air holes 13, it will enter the water pump housing. If there are cracks in the water pump housing, the gas will continuously gush out from the cracks, and then form bubbles in the water. At this time, the staff can judge the airtightness of the water pump housing and the position of its cracks by observing whether there are bubbles and the starting position of the bubbles.
