DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The assembly structure of the electric explosion-driven firing pin of the sub-control valve provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0046] like Figures 1 to 4 As shown, an embodiment of the present application provides an assembly structure of an electric explosion-driven firing pin of a sub-control valve, including a workbench 100 for placing a valve body 200 and a counter-shooting sensor unit arranged on a side of the workbench 100 away from the valve body 200.

[0047] When the length of the striker 210 passing through the valve body 200 is greater than the limit distance, the through-beam sensor unit can detect the striker 210 and output an alarm signal.

[0048] The limit distance is specifically a maximum preset length of the striker 210 passing through the valve body 200 .

[0049] During the assembly process, the valve body 200 is placed on the table top of the workbench 100, and the through-shooting sensor unit is located on the side of the workbench 100 away from the valve body 200. When the staff inserts the striker 210 into the cavity of the valve body 200 and pushes it further, one end of the striker 210 gradually penetrates the valve body 200. If the length of the valve body 200 passing through the striker 210 is greater than the limit distance, the through-shooting sensor unit can sense the striker 210. At this time, it means that the length of the striker 210 exceeds the valve body 200 and is within an unacceptable range. The through-shooting sensor unit outputs a warning signal, thereby reminding the staff to perform calibration in time.

[0050] In an embodiment of the present application, the above-mentioned assembly structure of the electric explosion-driven firing pin of the sub-control valve is adopted, and the length of the firing pin 210 exceeding the valve body 200 during assembly is monitored by a cross-shooting sensor component to avoid press-fit failure of the firing pin 210 and component interference caused by the firing pin 210 exceeding the limit distance. Compared with the manual measurement method, it is not only more accurate but also more efficient.

[0051] It can be understood that the length detection device of the firing pin 210 passing through the valve body 200 is not limited to a through-shooting sensor unit. For example, a pressure sensor can be directly set on the passage path of the firing pin 210, and a limit distance is set between the pressure sensor and the valve body 200. When the pressure sensor is hit by the firing pin 210 and generates a pressure signal, it means that the length of the firing pin 210 passing through the valve body 200 has reached the limit distance. At this time, an alarm can also be output to remind the staff. As long as the length of the firing pin 210 passing through the valve body 200 can be limited within the limit distance, it will not be elaborated here.

[0052] In a preferred embodiment, Figure 1 , Figure 2 As shown, the radiation sensing unit includes a radiation transmitting end 310 and a radiation receiving end 320 which are fixedly connected to the workbench 100 and located on a side of the workbench 100 away from the valve body 200 . The radiation transmitting end 310 can output radiation to the radiation receiving end 320 .

[0053] In the pushing direction of the striker 210 , the distances between the opposing transmitting end 310 , the opposing receiving end 320 and the valve body 200 are set to be limit distances, and the central axis of the striker 210 is located on the path of the output ray of the opposing transmitting end 310 .

[0054] It is understandable that when the length of the striker 210 exceeds the valve body 200 by more than the limit distance, the striker 210 will block the rays between the opposing transmitting end 310 and the opposing receiving end 320. At this time, the opposing receiving end 320 cannot sense the rays output by the opposing transmitting end 310, thereby outputting an alarm signal.

[0055] In a preferred embodiment, Figure 1 , Figure 2 As shown, it also includes a distance adjustment component 400 which is fixedly arranged on the workbench 100 and is used to adjust the extreme distance between the corresponding sensor unit and the valve body 200.

[0056] In the embodiment of the present application, the above-mentioned assembly structure of the electric explosion-driven firing pin of the sub-control valve is adopted, and the maximum distance between the opposing shooting sensor unit and the valve body 200 can be adjusted through the distance adjustment component 400, thereby improving the monitoring and alarm range of the penetration length of the firing pin 210, making the overall applicability and practicality of the device stronger.

[0057] It is understandable that the setting form of the distance adjustment component 400 is not limited to the above-mentioned one, that is, the distance adjustment component 400 can be set to be fixedly connected to the workbench 100, and can also be set to be an independent component. As long as the adjustment of the extreme distance between the opposing sensor unit and the valve body 200 can be achieved, it will not be elaborated here.

[0058] In a preferred embodiment, Figure 1 , Figure 2 As shown, two distance adjustment components 400 are symmetrically arranged on the end surface of the workbench 100 away from the valve body 200 about the central axis of the striker 210.

[0059] The opposite-beam transmitting end 310 and the opposite-beam receiving end 320 are respectively located on the transposition execution ends of the two distance adjustment components 400 .

[0060] In a preferred embodiment, Figure 1 , Figure 2 As shown, the distance adjustment assembly 400 includes a fixed plate 410 fixedly arranged on the end surface of the workbench 100 away from the valve body 200, a support plate 420 is fixedly arranged on the fixed plate 410, an adjustment rod 430 rotatably connected to the workbench 100 is rotatably arranged on the support plate 420, and a follower block 440 is threadedly connected to the adjustment rod 430.

[0061] The adjusting rod 430 is parallel to the central axis of the striker 210 . The end of the adjusting rod 430 away from the workbench 100 passes through the support plate 420 and is fixed with a handle 460 . The driven block 440 is fixedly mounted with the opposing transmitting end 310 or the opposing receiving end 320 .

[0062] It can be understood that the opposing transmitting end 310 and the opposing receiving end 320 are respectively fixedly arranged on the follower blocks 440 of the two distance adjustment components 400, and the height of the follower block 440 can be adjusted by rotating the handle 460, thereby adjusting the maximum distance between the opposing transmitting end 310, the opposing receiving end 320 and the valve body 200.

[0063] In a preferred embodiment, Figure 2As shown, a guide rail 450 slidably connected to the driven block 440 is provided on an end surface of the fixed plate 410 close to the driven block 440 .

[0064] It is understandable that the guide rail 450 can limit the position of the driven block 440 to prevent the driven block 440 from rotating when the handle 460 drives the adjusting rod 430 to rotate, thereby improving the stability of the driven block 440 when adjusting its position.

[0065] In a preferred embodiment, the limit distance is specifically set to 8 mm. The distance adjustment component 400 can adjust the through-shooting sensor unit to be 8 mm away from the valve body 200. When the length of the striker 210 passing through the valve body 200 is greater than 8 mm, the through-shooting sensor unit can sense the striker 210 and output an alarm signal.

[0066] It can be understood that since the workbench 100 itself has a certain thickness, the limit distance should be greater than and include the thickness of the workbench 100. For example, when the thickness of the workbench 100 is set to 0.5 mm, the distance between the through-bench sensor unit and the workbench 100 is set to 7.5 mm; when the thickness of the workbench 100 is set to 2 mm, the distance between the through-bench sensor unit and the workbench 100 is set to 6 mm.

[0067] In a preferred embodiment, Figure 1 As shown, a pushing tool 500 connected to the striker 210 and used for applying a pushing force to the striker 210 is also included.

[0068] Among them, the end of the pushing tool 500 close to the striker 210 is a rubber contoured part that cooperates with the striker 210, and the end away from the striker 210 is a handle part.

[0069] It is understandable that, after the rubber portion of the pushing tool 500 is connected to the corresponding end of the striker 210 , the staff can manually push the striker 210 into the valve body 200 through the handle portion of the pushing tool 500 .

[0070] It is understandable that the contoured portion of the pushing tool 500 is not limited to the above-mentioned materials, and can also be set to other flexible materials, as long as it can ensure that no mechanical damage is caused to the firing pin 210, which will not be elaborated here.

[0071] In a preferred embodiment, Figure 4 As shown, the workbench 100 is provided with a through hole 110 for the striker 210 to pass through.

[0072] In a preferred embodiment, Figure 1 , Figure 3 , Figure 4 As shown, a positioning assembly 600 is also included, which is disposed on the workbench 100 and is used to position the valve body 200 .

[0073] In a preferred embodiment, Figure 1 , Figure 3 , Figure 4 As shown, the positioning assembly 600 includes four limiting slide grooves 620 arranged in a circular array on the workbench 100 about the central axis of the through hole 110, and abutment plates 610 that can abut against the corresponding side end surfaces of the valve body 200 are slidably arranged in the limiting slide grooves 620.

[0074] A locking assembly is provided between the abutment plate 610 and the workbench 100 , and the locking assembly can limit the relative position of the abutment plate 610 in the limiting sliding groove 620 .

[0075] In an embodiment of the present application, the above-mentioned assembly structure of the electric explosion-driven firing pin of the sub-control valve is adopted. By adjusting the relative position of the abutment plate 610 in the limiting slide groove 620, the valve body 200 can be adaptively positioned in contact with it based on its contour, thereby ensuring the stability of the valve body 200 during the press-fitting process of the firing pin 210 and ensuring the press-fitting accuracy.

[0076] In a preferred embodiment, Figure 4 As shown, the abutting plate 610 includes a pressing portion 611 for abutting against the valve body 200 and a limiting sliding portion 612 fixedly connected to the pressing portion 611 .

[0077] The limiting sliding portion 612 is in an inverted T-shape and is slidably disposed in the limiting sliding groove 620 . The limiting sliding groove 620 matches the shape of the limiting sliding portion 612 and can limit the displacement of the limiting sliding portion 612 along the axial direction of the through hole 110 .

[0078] The limiting sliding groove 620 extends to the edge of the workbench 100 away from one end of the through hole 110 , so as to facilitate the installation of the limiting sliding portion 612 of the abutment plate 610 in the limiting sliding groove 620 .

[0079] In a preferred embodiment, Figure 3 , Figure 4 As shown, the locking assembly includes at least one locking hole 630 axially extending through the through hole 110 on the pressing portion 611 , and a locking bolt 640 is threadedly connected to the locking hole 630 .

[0080] The end of the locking bolt 640 close to the workbench 100 can abut against the corresponding side end surface of the workbench 100 .

[0081] It can be understood that after the push plate 610 slides in the limiting groove 620 and abuts against the corresponding side end surface of the valve body 200, it can be abutted against the workbench 100 by rotating the locking bolt 640. Under the friction force of the locking bolt 640 and the workbench 100, the relative position of the push plate 610 in the limiting groove 620 is restricted, thereby maintaining the resistance state to the valve body 200.

[0082] It is understandable that the structural form of the locking assembly is not limited to the above-mentioned one, as long as it can achieve the limitation of the abutment plate 610, which will not be elaborated here.

[0083] In a preferred embodiment, Figure 1 As shown, it also includes a plurality of legs 700 fixedly arranged on an end surface of the workbench 100 away from the valve body 200 and used to support the workbench 100 .

[0084] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0085] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
