Description

Technical Field

[0001] This application relates to the field of nozzle airtightness testing technology, and in particular to a nozzle sealing testing device. Background Technology

[0002] A nozzle typically consists of a housing, an electromagnetic drive assembly, a wiring harness connector, and a valve core. By energizing the electromagnetic drive assembly, the valve core opens the injection port to spray the medium. In the non-operating state, the valve core closes the injection port. Nozzle sealing testing is a critical quality inspection step to ensure that the nozzle does not leak at the injection port under specific pressure or environmental conditions.

[0003] Existing nozzle sealing testing devices (such as the injector air tightness testing device with announcement number CN208953209U) can perform sealing tests on injectors, but these devices can only test a single injector at a time, resulting in low testing efficiency. Furthermore, when large-scale testing is required, multiple testing devices are needed, leading to relatively high costs. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a nozzle sealing performance testing device that can simultaneously test the sealing performance of multiple nozzles. It is simple and convenient to operate, provides intuitive observation, has a concise overall structure, and can significantly reduce manufacturing costs. The technical solution adopted is as follows:

[0006] Preferably, the support platform is tilted and mounted on the bracket.

[0007] Its technical advantage lies in the fact that by tilting the support platform, the nozzle is tilted as a whole, so that the sealing performance of the nozzle can be observed directly.

[0008] More preferably, the included angle between the front end of the bracket and the support platform is A, where 10°≤A≤45°.

[0009] Preferably, each of the testing stations is provided with a mounting base for supporting the nozzle; the support platform is provided with a limiting component for fixing the mounting base.

[0010] Its technical effect is that: by limiting the mounting base through the limiting component, different mounting bases can be replaced according to different nozzle specifications, while avoiding the mounting base from rotating with the nozzle.

[0011] Preferably, the bracket includes a base plate and a top plate, with a support column connecting the top plate and the base plate, and the drive mechanism is connected to the top plate.

[0012] Preferably, it also includes a guide component for guiding the movement of the gas supply platform.

[0013] Its technical effect is that the guide component can prevent the air supply platform from rotating, ensuring that the air inlet connector on it can be accurately connected to the nozzle air inlet.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] (1) This application can install multiple nozzles at the same time, and can test the sealing performance of multiple nozzles at one time, which can greatly improve the testing efficiency; and the overall structure is simple and easy to operate, which can reduce manufacturing costs.

[0016] (2) By arranging the overall structure at an angle, it is easier to observe the nozzle test results directly when testing the nozzle sealing performance.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] See Figures 1 to 3 To further elaborate on this application:

[0030] Combination Figure 1 The nozzle sealing performance testing device includes a bracket 10 and a drive mechanism 40, as well as a support platform 20 and an air supply platform 30 disposed opposite to each other on the bracket 10. The support platform 20 has several testing stations 200, each with a mounting groove for placing a nozzle 00. The drive mechanism 40 can be a cylinder; however, it can also be other linear drive mechanisms 40.

[0031] Combination Figure 2 In this embodiment, the support 10 includes a base plate 120 and a top plate 110, with a support column 130 connecting the top plate 110 and the base plate 120. The drive mechanism 40 is connected to the top plate 110. The support platform 20 and the gas supply platform 30 are both located between the top plate 110 and the base plate 120.

[0032] The air supply platform 30 is located on top of the support platform 20. The air supply platform 30 is connected to the drive mechanism 40. An air inlet connector 300 corresponding to the testing station 200 is detachably connected to the air supply platform 30 for supplying air to the nozzle 00. The air inlet connector 300 is connected to an air supply device. The drive mechanism 40 drives the air supply platform 30 to move closer to or further away from the support platform 20, causing the air inlet connector 300 to connect or disconnect from the air inlet of the nozzle 00. This allows for simultaneous sealing testing of multiple nozzles 00, greatly improving testing efficiency, and features a simple overall structure and low manufacturing cost.

[0033] In use, first install the nozzle 00 in the detection station 200, and then use the drive mechanism 40 to bring the air supply platform 30 close to the nozzle 00 so that the air inlet connector 300 on the air supply platform 30 connects with the air inlet of the nozzle 00 to supply air to the nozzle 00 and press the nozzle 00 tightly. Then immerse the spray end of the nozzle 00 in the detection medium (such as water or oil) and observe whether there are bubbles.

[0034] Combination Figure 2 In this embodiment, the support platform 20 is inclinedly mounted on the bracket 10. By tilting the support platform 20, the nozzle 00 mounted on it is arranged in an inclined manner; wherein, the front end of the bracket 10 ( Figure 2 The angle between the right end of the bracket 10 and the support platform 20 is A, where 10°≤A≤45°; preferably, the angle A between the bracket 10 and the support platform 20 is 25°, so that one end of the nozzle 00 on the support platform 20 will extend to the right and the whole is not easy to tip over; compared with the existing method of setting the nozzle 00 vertically for testing, this application arranges the nozzle 00 at an angle to make the sealing performance of the nozzle 00 more intuitive to observe.

[0035] Since the nozzle 00 is inclined, the spraying end of the nozzle 00 needs to be immersed in the detection medium in order to avoid the wiring harness plug of the nozzle 00 coming into contact with the detection medium.

[0036] Combination Figure 3 In this embodiment, each of the detection stations 200 is provided with a mounting base 70 for supporting the nozzle 00; wherein, the mounting base 70 is provided with a stepped through groove 710 for placing the nozzle 00, and the side of the mounting base 70 is provided with a limiting groove 720 communicating with the through groove 710 for restricting the nozzle 00 from rotating within the mounting base 70, and the wiring harness plug of the nozzle 00 is snapped into the limiting groove 720.

[0037] The air intake connector 300 is detachably connected to the air supply platform; wherein, the air intake connector 300 can be detached and connected by bolts, which is not restricted here.

[0038] The support platform 20 is equipped with a limiting component 60 for fixing the mounting base 70. The limiting component 60 includes a mounting hole and a locking member threadedly connected to the mounting hole, which can be a bolt; the mounting base 70 is locked by the locking member to prevent it from driving the nozzle 00 to rotate. Therefore, when it is necessary to test nozzles 00 of different specifications, only the mounting base 70 that matches the nozzle 00 needs to be replaced, which can further reduce costs and has good versatility.

[0039] In this embodiment, a guide assembly 50 is also included, which guides the movement of the air supply platform 30. The guide assembly 50 includes a guide shaft and a guide sleeve. The guide sleeve is mounted on the air supply platform 30. The guide shaft connects the top plate 110 and the support platform 20, and the guide sleeve is fitted over the guide shaft. The guide assembly 50 prevents the air supply platform 30 from rotating, ensuring that the air inlet connector 300 on it can accurately align with the air inlet of the nozzle 00.
