Description

Technical Field

[0001] The utility model belongs to the technical field of airtight detection, and particularly relates to an airtight detection device. Background Art

[0002] A quick connector for air pipes is a connector that can achieve the connection or disconnection of pipelines without tools. The quick connector for air pipes is suitable for the quick connection of various gas pipelines and is composed of internal and external threads and male and female head components. In order to prevent gas leakage of the air pipe at the quick connector, certain requirements are put forward for the airtightness of the quick connector for air pipes.

[0003] When performing an airtightness test on a quick connector for air pipes, gas with a preset air pressure is usually injected into the quick connector, and then the feedback air pressure value is obtained and analyzed to detect the airtightness of the quick connector for air pipes. When the feedback air pressure value is stable and consistent with the preset air pressure value, it indicates that the airtightness of the quick connector for air pipes is good at this time; otherwise, it indicates that the airtightness does not meet the requirements. Existing detection methods mostly adopt manual operation to detect one by one, and the above methods can no longer meet the production requirements, and cannot meet the requirements of quickly fixing the quick connector for air pipes and accurately detecting the airtightness of the quick connector for air pipes.

[0026] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figure 1 , the airtight detection device in an embodiment of the present utility model includes a mounting table 1, a clamping assembly 2, and a gas supply member 3.

[0028] Referring to Figure 1 and Figure 2 , the mounting table 1 is provided with a station for positioning the quick connector. The clamping assembly 2 is installed on the mounting table 1. The clamping assembly 2 includes a driving plate 21 and two side pushing blocks 22 that are slidably engaged with the driving plate 21. The two side pushing blocks 22 include a clamping position where they approach each other to clamp the quick connector on the station and a release position where they move away from each other. When the driving plate 21 reciprocates, the two side pushing blocks 22 are slidably guided to switch between the clamping position and the release position. The gas supply member 3 is drivably engaged with the quick connector on the station to fill the quick connector with gas having a preset air pressure.

[0029] Therefore, when performing airtightness detection on the quick connector, first drive the two side pushing blocks 22 to slide to the release position through the driving plate 21, then place the quick connector on the station of the mounting table 1, and then drive the two side pushing blocks 22 to slide to the clamping position for clamping the quick connector through the driving plate 21. Finally, fill the quick connector with gas having a preset air pressure through the gas supply member 3, and the airtightness detection of the quick connector can be completed by the feedback air pressure data value.

[0030] Referring to Figure 2 and Figure 3 , one of the side pushing block 22 and the driving plate 21 is provided with a slot hole 23, and the other is provided with a sliding rod 24 that can be slidably engaged with the slot hole 23. When the driving plate 21 reciprocates, the sliding rod 24 cooperates with the hole wall of the slot hole 23 to slide, so as to guide the two side pushing blocks 22 to slide and switch between the clamping position and the release position. In this embodiment, the clamping assembly 2 further includes a clamping driving member 25. The clamping driving member 25 is fixedly installed on the mounting table 1, and the clamping driving member 25 drives the driving plate 21 to reciprocate. Among them, the clamping driving member 25 can be a device such as a cylinder.

[0031] In this embodiment, referring to Figure 3, the slot 23 is provided on the driving plate 21, and the slide bar 24 is installed on the side push block 22 as an example for illustrative description, which is not a limitation of the present application. In other embodiments, the slot 23 can also be provided on the side push block 22, and the slide bar 24 can also be installed on the driving plate 21.

[0032] Reference Figure 2 and Figure 3 , the reciprocating direction of the driving plate 21 is perpendicular to the sliding direction of the side push block 22, and the extending direction of the slot 23 on at least one side push block 22 or the driving plate 21 intersects with the reciprocating direction of the driving plate 21. Further, in order to enhance the sliding stability of the side push block 22, at least two sets of sliding rods 24 and slots 23 are provided between the side push block 22 and the driving plate 21, and the extending directions of the slots 23 are the same.

[0033] In this embodiment, the extending directions of the two side push blocks 22 or the slots 23 on the driving plate 21 intersect with the reciprocating direction of the driving plate 21. It can be understood that in this case, under the action of the driving plate 21, the two side push blocks 22 can move toward or away from each other by a certain distance to switch between the clamping position and the avoidance position.

[0034] In other embodiments, the extending direction of the push block 22 on one side or the slot hole 23 on the driving plate 21 may intersect with the reciprocating direction of the driving plate 21, and the extending direction of the push block 22 on the other side or the slot hole 23 on the driving plate 21 may be parallel to the reciprocating direction of the driving plate 21. It can be understood that in this case, under the action of the driving plate 21, only the push block 22 on one side can be moved closer to or away from the push block 22 on the other side, so that the push blocks 22 on both sides can switch between the clamping position and the avoidance position.

[0035] Specifically, in this embodiment, two groups of slots 23 are correspondingly opened on the driving plate 21, and one group of slots 23 is provided with two, and each group of slots 23 is slidably matched with two slide bars 24 on the same side push block 22. When the clamping driving member 25 drives the driving plate 21 to reciprocate, the hole wall of the slot 23 on the driving plate 21 guides the slide bar 24 to move, so that the slide bar 24 drives the side push block 22 fixedly connected thereto to move, so that the side push blocks 22 on both sides switch between the clamping position and the avoidance position.

[0036] Reference Figure 2 and Figure 3 The clamping assembly 2 also includes a clamping block group 26, which includes a first clamping block and a second clamping block for clamping the quick connector. The adjacent side walls of the push blocks 22 on both sides are provided with mounting grooves, and the first clamping block and the second clamping block are correspondingly installed in the mounting grooves. The first clamping block and the second clamping block in the clamping block group 26 are both provided with clamping walls on the adjacent side walls. When the push blocks 22 on both sides are in the clamping position, the clamping walls abut against the peripheral side walls of the quick connector, such asFigure 2 as shown

[0037] Therefore, the first clamping block and the second clamping block cooperate to be in surface contact with the quick connector, which can reduce the possibility of damage to the quick connector to be tested due to excessive local clamping force. At the same time, the first clamping block and the second clamping block can be replaced according to the actual size of the quick connector, thereby improving the adaptability of the airtight detection device of the present invention to quick connectors of different models.

[0038] In this embodiment, the mounting table 1 is provided with four stations, and the clamping block groups 26 are correspondingly provided with four groups, so that the testing of multiple quick connectors can be completed quickly and efficiently. Of course, in other embodiments, the number of stations of the mounting table 1 and the number of clamping block groups 26 can also be other numbers, such as three, five, six or even more.

[0039] Referring to Figure 3 , at the station, the mounting table 1 is provided with a positioning seat 4. The positioning seat 4 is provided with a positioning hole 41 for inserting the quick connector therein, and a flexible limiting ring 5 is fixed in the positioning hole 41. The positioning seat 4 facilitates quickly positioning the position of the quick connector before the clamping assembly 2 clamps and fixes the quick connector. The flexible limiting ring 5 can make the quick connector and the positioning seat 4 in soft contact, reducing the possibility of the quick connector being knocked and damaged.

[0040] Referring to Figure 1 , in this embodiment, the airtight detection device further includes a driving assembly 6 for driving the clamping assembly 2 and the air supply member 3 to move towards each other. After the clamping assembly 2 fixes the quick connector, by moving the clamping assembly 2 and the air supply member 3 both a certain distance, it can effectively ensure that the air supply member 3 is inserted into the quick connector, reducing the occurrence of missed insertion, thereby reducing the occurrence of misjudgment of the airtightness of the quick connector. The reason is that when the air supply member 3 is not fully inserted into the quick connector, there may be air leakage between the two at this time, resulting in a low measured air pressure value, and thus causing misjudgment of the airtightness of the quick connector.

[0041] Referring to Figure 4 , in this embodiment, the airtight detection device further includes a fixing plate 7 and a connecting plate 8. The mounting table 1 is arranged on one side of the fixing plate 7, and the air outlet end of the air supply member 3 is fixedly installed on the side of the connecting plate 8 close to the clamping assembly 2. The driving assembly 6 drives the mounting table 1 and the connecting plate 8 to move towards each other. Among them, the fixing plate 7 is fixedly connected to the external frame, so the position of the fixing plate 7 remains unchanged.

[0042] Referring to Figure 4, the driving assembly 6 includes a first driving member 61 for driving the movement of the mounting table 1 and a second driving member 62 for driving the movement of the connecting plate 8. The first driving member 61 and the second driving member 62 drive the mounting table 1 and the connecting plate 8 to move towards each other. Among them, both the first driving member 61 and the second driving member 62 can be selected as cylinders.

[0043] Referring to Figure 4 , the driving assembly 6 further includes a movable plate 63 and a movable rod 64. The first driving member 61 is fixedly installed on the side of the fixed plate 7 away from the mounting table 1. The movable plate 63 is fixedly connected to the output shaft of the first driving member 61. Both ends of the movable rod 64 are fixedly connected to the movable plate 63 and the mounting table 1 respectively, and the movable rod 64 is slidably engaged with the fixed plate 7. The first driving member 61 drives the movable plate 63 to move up and down, so as to drive the mounting table 1 to move up and down.

[0044] Referring to Figure 4 , in this embodiment, the airtight detection device further includes a guide rod 9. The guide rod 9 is fixedly installed on the fixed plate 7. Both the mounting table 1 and the connecting plate 8 are slidably installed with the guide rod 9. Therefore, when the first driving member 61 drives the mounting table 1 to move, under the action of the guide rod 9, the mounting table 1 can slide stably.

[0045] In this embodiment, referring to Figure 1 and Figure 4 , the driving assembly 6 further includes an upper template 65. There are four guide rods 9. The upper template 65 is fixedly connected to the side of the guide rod 9 away from the mounting plate. The second driving member 62 is installed on the upper template 65, and the output shaft of the second driving member 62 is fixedly connected to the connecting plate 8. Therefore, the second driving member 62 can drive the connecting plate 8 to approach or move away from the clamping assembly 2, and the guide rod 9 can also make the connecting plate 8 slide stably, so that the air supply member 3 can be effectively inserted into the quick connector.

[0046] Therefore, the airtight detection device of the present utility model can automatically clamp the quick connector through the clamping assembly 2, and can ensure the effectiveness of inserting the air supply member 3 into the quick connector through the coordinated operation of the driving assembly 6 and the air supply member 3, so that the airtightness detection of the quick connector can be completed quickly and accurately.
