[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 In this embodiment of the present invention, a washing machine drain valve sealing test device includes a clamping seat 3 for fixing the washing machine drain valve, and a test component 6 is provided above the clamping seat 3; the test component 6 has a test head 65 that engages with the washing machine drain valve, the test head 65 is fixed on a connecting frame 64, and the upper end of the connecting frame 64 is fixed to the cylinder rod of the test cylinder 63.
[0031] The top of the test head 65 is connected to an air inlet pipe 15 via a threaded air nozzle; the air inlet pipe 15 is equipped with a pressure gauge and is connected to an air source.
[0032] By adopting the above technical solution, when using the device, first fix the washing machine drain valve on the clamping seat 3, then extend the cylinder rod of the test cylinder 63, close the test head 65 with the washing machine drain valve, then input air pressure through the air inlet pipe 15 and close the solenoid valve on the air inlet pipe 15 to maintain static pressure. By observing the pressure value of the pressure gauge, it is determined whether there is air leakage between the test head 65 and the washing machine drain valve, thus determining whether the washing machine drain valve is qualified.
[0033] In this embodiment, the two ends of the test cylinder 63 are fixed with a fixing frame 62, and a slide block 61 is fixed to the outside of the fixing frame 62 by bolts; the slide block 61 is slidably connected to the guide rod 7; the two ends of the guide rod 7 are fixedly connected to the front fixing seat 5 and the rear fixing seat 8 respectively; the front fixing seat 5 and the rear fixing seat 8 are fixed on the frame body 1.
[0034] More specifically, the rear side of the test component 6 is fixedly connected to the cylinder rod of the sliding cylinder 9; the sliding cylinder 9 is fixed to the top of the rear fixed seat 8 by the cylinder fixing bracket 10.
[0035] By adopting the above technical solution, after the test is completed, because the test head 65 and the washing machine drain valve are closely matched, when the cylinder rod of the sliding cylinder 9 retracts, the washing machine drain valve will be lifted. Then the cylinder rod of the sliding cylinder 9 retracts, causing the slide block 61 in the test assembly 6 to slide backward along the guide rod 7 to the top of the unloading platform 11 for removal.
[0036] In this embodiment, a feeding platform 11 is provided between the front fixed seat 5 and the rear fixed seat 8; a mechanical claw 12 is fixed on the feeding platform 11.
[0037] By adopting the above technical solution, when the washing machine drain valve slides to the top of the unloading platform 11, the mechanical claw 12 clamps the washing machine drain valve, and then the cylinder rod of the test cylinder 63 extends and retracts, thereby removing the washing machine drain valve; this eliminates manual operation and greatly improves the automation level of the equipment.
[0038] In this embodiment, there are two clamping seats 3, which are symmetrically arranged and fixed on the rotating disk 2; the rotating disk 2 is connected to the rotating cylinder 4; the rotating cylinder 4 is fixed to the bottom of the frame body 1.
[0039] By adopting the above technical solution, two clamping seats 3 are provided, which can be used alternately, so that when one washing machine drain valve is being tested, the drain valve of another washing machine can be installed, which greatly improves the testing efficiency of the equipment.
[0040] In this embodiment, a rectangular groove is provided on the top of the frame body 1, and a locking member 13 is slidably connected in the rectangular groove. The upper end of the locking member 13 is U-shaped, and the lower end is fixed to the cylinder rod of the stop cylinder 14. The stop cylinder 14 is fixed to the bottom of the frame body 1.
[0041] The rotary cylinder 4 can drive the rotary disk 2 to rotate, thereby enabling the two clamping seats 3 to work and test alternately. In order to prevent rotation during testing, the cylinder rod of the stop cylinder 14 extends, so that the locking part 13 locks the clamping seat 3, thereby preventing the rotary disk 2 from rotating.
[0042] The working principle of this utility model is as follows: When in use, first fix the washing machine drain valve on the clamping seat 3, then extend the cylinder rod of the test cylinder 63, close the test head 65 with the washing machine drain valve, then input air pressure through the air inlet pipe 15 and close the solenoid valve on the air inlet pipe 15 to maintain static pressure. By observing the pressure value of the pressure gauge, it is determined whether there is air leakage between the test head 65 and the washing machine drain valve, thereby determining whether the washing machine drain valve is qualified.
[0043] While testing the drain valve of one washing machine, another washing machine drain valve is installed, allowing the two clamping seats 3 to be used alternately. After the test is completed, due to the tight fit between the test head 65 and the washing machine drain valve, when the cylinder rod of the sliding cylinder 9 retracts, it lifts the washing machine drain valve. Then, the cylinder rod of the sliding cylinder 9 retracts, causing the slide seat 61 in the test assembly 6 to slide backward along the guide rod 7 to the top of the unloading platform 11. The mechanical claw 12 clamps the washing machine drain valve, and then the cylinder rod of the test cylinder 63 extends and retracts, thereby removing the washing machine drain valve. This eliminates manual operation and greatly improves the automation level of the equipment.
[0044] Meanwhile, the rotary cylinder 4 can drive the rotary disk 2 to rotate, thereby enabling the two clamping seats 3 to work and test alternately; in order to prevent rotation during testing, the cylinder rod of the stop cylinder 14 extends, so that the locking member 13 locks the clamping seat 3, thereby preventing the rotary disk 2 from rotating.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
