Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of underwater connector detection, and specifically relates to an auxiliary tooling for underwater connectors. Background Art
[0002] Underwater connectors are connecting devices used to transmit signals, electricity or data in underwater environments. With the implementation of the national marine strategy, the use of underwater connectors is becoming more and more extensive. Since underwater connectors are used in underwater environments and the water pressure they withstand increases with the increasing depth of their installation locations, the waterproof performance and pressure resistance of underwater connectors have become important evaluation criteria for evaluating whether underwater connectors are qualified. Therefore, underwater connectors need to be tested for their waterproof and pressure resistance before leaving the factory or before use.
[0003] In related technologies, an underwater connector is usually installed on the end cover of a pressure vessel, and then water is filled into the pressure vessel and pressurized inside the pressure vessel so that the underwater connector is placed in a set water pressure environment to detect the waterproof and pressure resistance performance of the underwater connector.
[0004] To facilitate the installation of an underwater connector on the end cap of a pressure vessel, a connection hole must be opened in the end cap and the underwater connector installed in the connection hole. Different underwater connector models require connection holes of different diameters, which necessitates the replacement or modification of the end cap of the pressure vessel. This results in poor flexibility in existing testing methods and high testing costs for underwater connectors. Furthermore, when testing underwater connectors, their waterproof performance is not clearly evident, resulting in poor waterproof performance testing accuracy. Utility Model Content
[0005] The present application provides an auxiliary tooling for underwater connectors to increase the detection flexibility of underwater connectors, reduce the detection cost of underwater connectors, and improve the accuracy of waterproof performance detection of underwater connectors.
[0006] The technical solutions adopted in this application are:
[0007] An auxiliary tooling for an underwater connector includes a cylinder, a first cylinder cover, a second cylinder cover, and a third cylinder cover. The cylinder has a first end and a second end opposite to the first end. The first cylinder cover is detachably connected to the first end, the second cylinder cover is detachably connected to the second end, the third cylinder cover is detachably connected to the second end and can replace the second cylinder cover. The first cylinder cover is provided with a mounting hole for connecting the underwater connector, and the third cylinder cover is provided with a communicating hole communicating with the internal space of the cylinder.
[0008] By adopting the above technical solution, when using the auxiliary tooling in the present application to inspect the underwater connector, the underwater connector is first installed in the mounting hole, and then the auxiliary tooling with the underwater connector installed is placed in the pressure vessel, and then the end cover of the pressure vessel is covered and water is injected into the pressure vessel and pressurized to make the pressure in the pressure vessel reach the set value. If the underwater connector disintegrates or leaks after a period of time, it means that the underwater connector is defective. When the defective underwater connector is cracked, the wall of the pressure vessel can block the cracked underwater connector to avoid the cracked fragments from causing harm to the staff, thereby increasing the safety when inspecting the underwater connector.
[0009] In addition, when using the auxiliary tooling in the present application to inspect the underwater connector, the second cylinder cover can also be removed, and then the third cylinder cover can be installed on the end of the cylinder body, and the air supply pipe of the external air supply equipment can be connected to the connecting hole. Then, the auxiliary tooling with the underwater connector installed can be placed in the water tank, and the air supply device can be used to supply air into the cylinder body. Then, observe whether the underwater connector is bubbling to further inspect the waterproof performance of the underwater connector, so that whether the underwater connector is leaking is more intuitive, avoiding false detection, thereby improving the detection accuracy of the underwater connector and improving the customer's usage experience.
[0010] In addition, since the underwater connector is usually installed on the outside of the chassis when in use, installing the underwater connector on the outside of the auxiliary tooling can also simulate the actual usage scenario of the underwater connector, thereby further improving the detection accuracy of the underwater connector to ensure the reliability of the underwater connector leaving the factory.
[0011] At the same time, when the auxiliary tooling in the present application is used to inspect underwater connectors, the need to open a connection hole on the end cover of the pressure vessel is eliminated, thereby enabling multiple underwater connectors to be placed in the pressure vessel at the same time, thereby improving the inspection efficiency of the underwater connectors; and when inspecting underwater connectors of different models, only the first cylinder cover needs to be replaced, thereby greatly reducing the inspection cost of the underwater connector and increasing the flexibility of the auxiliary tooling.
[0012] Optionally, both ends of the cylinder are provided with sealing parts, and the first cylinder cover, the second cylinder cover and the third cylinder cover can all abut against the sealing parts to seal the cylinder.
[0013] By adopting the above technical solution, due to the presence of the sealing part, the sealing performance of the connection between the first cylinder cover and the cylinder body, and the sealing performance of the connection between the second cylinder cover or the third cylinder cover and the cylinder body are increased, thereby avoiding the situation where when the gas supply equipment fills gas into the cylinder, the connection between the first cylinder cover and the cylinder body leaks and produces bubbles, which affects the judgment of the inspection personnel, thereby greatly improving the inspection accuracy of the underwater connector.
[0014] Optionally, the sealing portion is a sealing ring, and both ends of the cylinder are provided with accommodating grooves, and at least a portion of the sealing ring is located in the accommodating grooves.
[0015] By adopting the above technical solution, since the sealing part is a sealing ring, the sealing between the first cylinder cover and the cylinder body, and the sealing between the second cylinder cover or the third cylinder cover and the cylinder body are further improved, and the effect of facilitating the replacement of the sealing part can be achieved; since at least part of the sealing ring is located in the accommodating groove, on the one hand, the stability of the sealing ring is increased, and the relative movement between the sealing ring and the end of the cylinder body, which may cause the sealing ring to be misaligned, is avoided; on the other hand, the difficulty of assembling the first cylinder cover, the second cylinder cover and the third cylinder cover is reduced.
[0016] Optionally, the first cylinder cover, the second cylinder cover and the third cylinder cover are all provided with an extension portion capable of extending into the interior of the cylinder body, and the outer peripheral surface of the extension portion is in contact with and fits against the inner wall of the cylinder body.
[0017] By adopting the above technical solution, since the first cylinder cover, the second cylinder cover and the third cylinder cover are all provided with an extension portion that can extend into the interior of the cylinder body, on the one hand, the difficulty of assembling the first cylinder cover, the second cylinder cover and the third cylinder cover is reduced to improve the assembly efficiency of the three, and on the other hand, the sealing between the first cylinder cover and the cylinder body and the sealing between the second cylinder cover or the third cylinder cover and the cylinder body are increased.
[0018] Optionally, a connecting portion and a matching portion are provided on the outer peripheral surface of the cylinder, and the matching portion can be connected and matched with the connecting portion.
[0019] By adopting the above technical solution, when testing multiple underwater connectors at the same time, the multiple underwater connectors are respectively installed on multiple auxiliary toolings, and then the connecting parts and mating parts on two adjacent auxiliary toolings are connected together to increase the stability of the two adjacent auxiliary toolings, thereby avoiding the underwater connector from tilting in the pressure vessel during the testing process of the underwater connector.
[0020] Optionally, the connecting portion includes a connecting ring sleeved on the cylinder and a connecting sleeve provided on the connecting ring, and the mating portion includes a mating ring sleeved on the cylinder and a connecting rod provided on the mating ring, and the connecting rod can be passed through the connecting sleeve.
[0021] By adopting the above technical solution, when connecting two adjacent auxiliary tooling together, the connecting rod on one of the auxiliary tooling is inserted into the connecting sleeve of the other auxiliary tooling to achieve the connection of the two adjacent auxiliary tooling. In this process, it is only necessary to drive the auxiliary tooling in its axial direction, thereby achieving the effect of facilitating the connection of the two adjacent auxiliary tooling together.
[0022] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0043] In addition, when using the auxiliary tooling in the present application to inspect the underwater connector, the second cylinder cover 3 can also be removed, and then the third cylinder cover 4 can be installed on the end of the cylinder body 1, and the air supply pipe of the external air supply equipment can be connected to the connecting hole 41. Then, the auxiliary tooling with the underwater connector installed can be placed in the water tank, and the air supply device can be used to supply air to the cylinder body 1. Then, observe whether the underwater connector is bubbling to further inspect the waterproof performance of the underwater connector, so that whether the underwater connector is leaking is more intuitive, avoiding false detection, and improving the detection accuracy of the underwater connector, thereby improving the customer's usage experience.
[0044] In addition, since the underwater connector is usually installed on the outside of the chassis when in use, installing the underwater connector on the outside of the auxiliary tooling can also simulate the actual usage scenario of the underwater connector, thereby further improving the detection accuracy of the underwater connector to ensure the reliability of the underwater connector leaving the factory.
[0045] At the same time, when the auxiliary tooling in the present application is used to inspect underwater connectors, the need to open a connection hole on the end cover of the pressure vessel is eliminated, thereby enabling multiple underwater connectors to be placed in the pressure vessel at the same time, thereby improving the inspection efficiency of the underwater connectors; and when inspecting underwater connectors of different models, only the first cylinder cover 2 needs to be replaced, thereby greatly reducing the inspection cost of the underwater connector and increasing the flexibility of the auxiliary tooling.

[0049] The present application does not specifically limit the structure of the sealing portion 111. Preferably, refer to Figure 4 and Figure 5 The sealing portion 111 is a sealing ring. Both ends of the cylinder 1 are provided with a receiving groove 11, and at least part of the sealing ring is located in the receiving groove 11.

[0051] In other embodiments, the sealing portion 111 may also be a sealing sheet provided at the end of the cylinder 1 to reduce the production cost of the auxiliary tooling.

Preferably, the connecting portion 12 includes a connecting ring sleeved on the cylinder 1 and a connecting sleeve provided on the connecting ring, and the matching portion 13 includes a matching ring sleeved on the cylinder 1 and a connecting rod provided on the matching ring, and the connecting rod can be passed through the connecting sleeve.
[0058] When connecting two adjacent auxiliary toolings together, the connecting rod on one of the auxiliary toolings is inserted into the connecting sleeve of the other auxiliary tooling to achieve the connection of the two adjacent auxiliary toolings. During this process, it is only necessary to drive the auxiliary tooling in its axial direction, thereby achieving the effect of facilitating the connection of the two adjacent auxiliary toolings together.
