[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the 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 of the embodiments.

[0021] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0022] Embodiment

[0023] First of all, it should be noted that the first direction involved in this application refers to the X-axis direction, and the second direction is the Y-axis direction.

[0024] In order to solve the problem that the existing valve core airtightness detection equipment cannot automatically clamp the valve core and cannot automatically seal the valve core, resulting in inaccurate detection results, referring to Figure 1 and Figure 2 as shown, this application discloses a valve core airtightness detection equipment, including: a detection platform 10, two support blocks 20 are arranged above the detection platform along the first direction, and groove bodies 11 are respectively opened on both sides of the upper surface of the detection platform along the first direction near the support blocks;

[0025] A clamping mechanism 30, the clamping mechanism includes a first flipping clamping component 31 and a second flipping clamping component 32, and the first flipping clamping component and the second flipping clamping component are oppositely arranged between the two support blocks along the second direction; (the structures of the first flipping clamping component and the second flipping clamping component are the same;

[0026] ) A leakage detection mechanism 40, the leakage detection mechanism includes a bidirectional driving component 41, an air inflation pump 42, a gas leakage detector 43, a first sealing head 44 and a second sealing head 45, (the structures of the first sealing head and the second sealing head are the same) the bidirectional driving component is arranged at the bottom of the detection platform along the first direction, the first sealing head and the second sealing head respectively pass through the groove bodies and are connected to the two driving parts of the bidirectional driving component, first L-shaped air channels 441 and second L-shaped air channels are respectively opened in the first sealing head and the second sealing head, the air inflation pump and the gas leakage detector are respectively arranged on both sides of the detection platform along the first direction, the air inflation pump is connected to the first L-shaped air channel through a trachea a 46, and the gas leakage detector is connected to the second L-shaped air channel through a corrugated trachea b 47.

[0027] In a specific embodiment, an operator or a manipulator places the valve core to be detected on two support blocks. The first flipping and clamping assembly and the second flipping and clamping assembly will clamp and fix the valve core from two positions. After that, the bidirectional driving assembly drives the first sealing head and the second sealing head to move towards each other until the first sealing head and the second sealing head block both ends of the valve core. Next, the gas output by the air pump enters the first L-shaped air passage through the air pipe a and then enters the interior of the valve core. And after the gas enters the valve core, it will pass through the second L-shaped air passage and the corrugated air pipe b and enter the gas leak detector. After the air pump has filled the set amount of gas, if the gas leak detector detects that the amount of gas in the entire passage has decreased to the set amount, then it means that the airtightness of the valve core is unqualified; otherwise, it is qualified.

[0028] To facilitate the placement of the valve core, the present application respectively opens V-shaped grooves 21 for accommodating the valve core above the two support blocks. During the specific implementation process, the grooves opened on the two support blocks of the present application do not limit to this V-shaped groove shape. If other types of grooves can also achieve the functions of the present application, those skilled in the art can adaptively select.

[0029] In one of the preferred embodiment solutions, the first flipping and clamping assembly and the second flipping and clamping assembly of the present application are arranged in a staggered manner. Specifically, both the first flipping and clamping assembly and the second flipping and clamping assembly of the present application include a vertical block 322, a clamping block 323, and a flipping cylinder 321. The vertical block is fixed on the detection platform and a U-shaped groove 3221 is opened at its top. The clamping block is rotatably connected in the U-shaped groove through a hinge shaft. The flipping cylinder is arranged outside the vertical block and connects its output end to the hinge shaft (not shown). When clamping the valve core, the flipping cylinders included in the first flipping and clamping assembly and the second flipping and clamping assembly of the present application will both press the clamping blocks on the valve core.

[0030] In addition to the above structure, the present application also respectively sets a first conical silicone air nozzle 48 and a second conical silicone air nozzle 49 on the sides of the first sealing head and the second sealing head for blocking the valve core. The first conical silicone air nozzle is communicated with the first L-shaped air passage, and the first conical silicone air nozzle is communicated with the second L-shaped air passage. During the process of the bidirectional driving assembly driving the first sealing head and the second sealing head to move towards each other, the first conical silicone air nozzle and the second conical silicone air nozzle will be inserted into both ends of the valve core. In this way, the sealing of the valve core is ensured, and further, during the inflation detection process, the detection result can be guaranteed to be relatively accurate.

[0031] Specifically, the bidirectional driving assembly of the present application is a bidirectional driving cylinder or a bidirectional driving lead screw module. The bidirectional driving assemblies of these two structures are both known technologies, and during the specific implementation process, they can both realize driving the first plug and the second plug to move towards each other or away from each other.

[0032] In the description of this specification, the descriptions referring to terms such as "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0033] The above embodiments are only for illustrating the technical concept and features of the present utility model, and the purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit the protection scope of the present utility model. All equivalent transformations or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
