Description

Technical Field

[0001] The utility model belongs to the technical field of controller watertight testing, and in particular relates to a controller watertight tooling. Background Art

[0002] As an electronic device, the controller's internal structure needs to maintain good sealing to prevent external environmental factors, such as water, dust, etc., from damaging the internal components. Poor airtightness can lead to air leakage, affecting the service life and safety performance of the equipment.

[0003] For airtight NG controllers, it is necessary to find the leak point in a watertight manner. The traditional airtightness test method is to insert the inflation tube into the controller and seal the inflation port of the controller with clay for a watertight test. However, this method still has the following problems:

[0004] On the one hand, it is necessary to manually seal the area around the controller step by step. Sealing with clay is time-consuming and laborious, and the effectiveness of the clay seal cannot be confirmed. After being placed underwater, it may be found that the clay is not sealed well, resulting in the inability to determine the location of the product leak;

[0005] On the other hand, after the clay is sealed, the controller cannot withstand the impact of air pressure, which may cause perforation of the clay and affect the test. Utility Model Content

[0006] In view of this, in order to solve the problems existing in the prior art, the purpose of the utility model is to provide a controller watertight tooling, which has good sealing performance, no air leakage when the watertight tooling is connected to the controller, easy operation, and saves manpower and time.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A controller watertight tooling, comprising: a watertight tooling body, one end of the watertight tooling body is recessed inward to form a pair of interfaces, and the interfaces are interference-fitted with the controller;

[0009] An air inlet is provided on one side of the watertight tool body, the air inlet is communicated with the docking port, and the air inlet is connected with the inflation device.

[0010] The specific technical effect is: by adopting a watertight tooling body to connect with the controller, it is convenient to save manpower and time, and the connection sealing is ensured by the interference fit between the interface and the controller, ensuring that the test will not be affected by the leakage of the tooling itself after entering the water, and the leakage position of the product cannot be determined.

[0011] Furthermore, the controller includes a product part and a sealing ring, and the sealing ring is installed at the connection between the product part and the docking port.

[0012] The specific technical effect is that the docking position between the controller and the tooling is a position with a sealing ring, which further ensures the sealing of the connection.

[0013] Furthermore, the outline size of the docking port is smaller than the outline size of the sealing ring.

[0014] Furthermore, a fitting tolerance is obtained by subtracting the fitting tolerance from the fitting tolerance, and the fitting tolerance difference is -3.8 mm.

[0015] The specific technical effect is: the interface and the sealing ring are matched with negative tolerance to ensure that there will be no leakage when the tooling and the controller are connected.

[0016] Furthermore, an air joint is installed at the air inlet, and the air inlet of the watertight tooling body is connected to the inflation device through the air joint.

[0017] The specific technical effect is: air is inflated into the air inlet through the air joint.

[0018] Furthermore, a sealant is provided at the connection between the air joint and the air inlet.

[0019] The specific technical effect is: setting the sealant ensures that there will be no air leakage at the connection between the air joint and the air inlet, thereby improving the sealing performance of the tooling.

[0020] Furthermore, the watertight tooling body is forged from aluminum alloy.

[0021] Furthermore, a handle is provided on the watertight tool body.

[0022] The specific technical effect is: the handle is provided to facilitate the operator to hold the watertight tool body.

[0023] Furthermore, the outer edge of one end of the watertight tool body is recessed inward to form a hand position avoidance groove, and the hand position avoidance groove is arranged close to the handle.

[0024] The specific technical effect is: the hand position avoidance groove is used to play an avoidance role when holding the handle.

[0025] Furthermore, the handle is made of nylon.

[0026] The beneficial effects of the utility model are:

[0027] The watertight tooling body is conveniently connected to the controller, saving manpower and time. The interference fit between the interface and the controller ensures the sealing of the connection, ensuring that the test will not be affected by air leakage of the tooling itself after entering the water, making it impossible to determine the leakage location of the product.
