Detailed implementation manners

[0018] Hereinafter, the exemplary embodiments of the present application will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0019] The engine injector is a key component of the fuel injection system. The engine injector is used to accurately inject fuel into the engine combustion chamber, mix with air to form a combustible mixture, so that the engine can operate normally.

[0020] The engine injectors need to be tightened during the assembly process. For example, the fuel interface threads of the manifold injection injector need to be tightened, the high-pressure fuel interface of the direct injection injector needs to be tightened, and so on.

[0021] However, the engine injector in the prior art is assembled manually, and the assembly efficiency is low.

[0022] In order to at least solve the problem of low assembly efficiency of engine injectors in the prior art, an embodiment of the present application provides an engine injector assembly device that can automatically tighten the engine injector, thereby improving the assembly efficiency of the engine injector.

[0023] The embodiments of the present application also provide an engine injector assembly method applied to the engine injector assembly device 100 of the above embodiment.

[0024] The engine injector assembly device 100 and the engine injector assembly method according to the embodiment of the present application are described below with reference to the accompanying drawings.

[0025] Combination Figures 1 to 10 As shown, the engine injector assembly device 100 of the embodiment of the present application includes a base 10, a tightening device 20, an adjusting device 30 and a mounting device 40. The tightening device 20 includes a driving assembly 21 and at least two tightening members 22, and the at least two tightening members 22 act synchronously. The driving assembly 21 is in transmission connection with each tightening member 22, and is used to drive the at least two tightening members 22 to clamp the first end of the engine injector by moving closer to each other, or to drive the at least two tightening members 22 to release the first end by moving away from each other, and to drive the tightening members 22 to rotate around the vertical direction a.

[0026] The adjusting device 30 is connected to the base 10, and the adjusting device 30 is transmission-connected to the driving assembly 21, and is used to adjust the position of the tightening member 22. The mounting device 40 includes a mounting cylinder 41, a mounting assembly 42, and a push plate assembly 43. The mounting cylinder 41 is connected to the mounting assembly 42, and is used to place the second end of the engine injector. The mounting assembly 42 is arranged on the base 10, and the push plate assembly 43 is arranged on the mounting assembly 42. The push plate assembly 43 is arranged on the mounting cylinder 41 in a manner that it can move along the radial direction of the mounting cylinder 41, and is used to abut the second end together with the mounting cylinder 41 or separate from the second end.

[0027] The first end and the second end of the engine injector are two ends of the engine injector, and the engine injector can be tightened by fixing the second end of the engine injector and screwing the first end of the engine injector.

[0028] When it is necessary to tighten the engine injector, place the engine injector in the installation cylinder 41, drive the push plate assembly 43 to move the push plate assembly 43 in the radial direction of the installation cylinder 41 towards the engine injector, so that the push plate assembly 43 and the installation cylinder 41 jointly abut against the engine injector, and then fix the second end of the engine injector through the combined action of the push plate assembly 43 and the installation cylinder 41.

[0029] Adjust the position of the driving assembly 21 through the adjusting device 30, so as to adjust the position of the tightening member 22, make the position of the tightening member 22 opposite to the installation cylinder 41 in the vertical direction a, control the tightening member 22 to perform a closing action through the driving assembly 21, so that the tightening members 22 approach each other synchronously, and then clamp the first end of the engine injector under the combined action of the plurality of tightening members 22.

[0030] Drive the plurality of tightening members 22 to rotate around the vertical direction a through the driving assembly 21, so as to rotate the first end of the engine injector. Since the second end of the engine injector is fixed, the first end of the engine injector rotates relative to the second end, thereby tightening the engine injector.

[0031] After tightening the engine injector, control the tightening members 22 to move away from each other through the driving assembly 21, so as to release the first end of the engine injector, drive the push plate assembly 43 to move the push plate assembly 43 in the radial direction of the installation cylinder 41 away from the engine injector, so as to release the second end of the engine injector, and thus the engine injector can be removed.

[0032] The engine injector assembly equipment 100 of the present application can automatically tighten the engine injector, thereby improving the assembly efficiency of the engine injector. Moreover, the engine injector assembly equipment 100 of the present application can more precisely adjust the position and tightening force of the engine injector by adjusting the position of the tightening member 22 through the adjusting device 30, driving the tightening member 22 to clamp the engine injector through the driving assembly 21, and driving the tightening member 22 to tighten through the driving assembly 21, so as to reduce the error in the assembly process of the engine injector, and further improve the assembly quality of the engine injector.

[0033] Such as Figure 10As shown, in some embodiments, the tightening members 22 are arranged in sequence around the vertical direction a. The driving assembly 21 includes at least two driving members 211, and the driving members 211 are arranged in one-to-one correspondence with the tightening members 22. The driving member 211 includes a first motor 2111, a first threaded rod 2112, a first threaded cylinder 2113, a first limiting rod 2114, a limiting cylinder 2115 and an installation box 2116. The first threaded rod 2112, the first threaded cylinder 2113, the first limiting rod 2114 and the limiting cylinder 2115 all extend along the radial direction of the installation cylinder 41. The first motor 2111 is installed in the installation box 2116. One of the first threaded rod 2112 and the first threaded cylinder 2113 passes through the installation box 2116 and is in transmission connection with the first motor 2111. The other of the first threaded rod 2112 and the first threaded cylinder 2113 is connected to the tightening member 22. The first threaded cylinder 2113 is sleeved on the first threaded rod 2112 in a manner that can move along the radial direction of the installation cylinder 41 and is in threaded connection with the first threaded rod 2112. One of the installation box 2116 and the tightening member 22 is connected to the first limiting rod 2114, and the other of the installation box 2116 and the tightening member 22 is connected to the limiting cylinder 2115. The first limiting rod 2114 is arranged in the limiting cylinder 2115 in a slidable manner.

[0034] The first motor 2111 and one of the first threaded rod 2112 and the first threaded cylinder 2113 can be in transmission connection by means of meshing of gears or a gear set, or can be in transmission connection according to other transmission connection methods well-known to those skilled in the art.

[0035] Under the action of the first motor 2111, the first threaded rod 2112 rotates relative to the first threaded cylinder 2113, and the tightening member 22 has a tendency to rotate. Under the limiting action of the first limiting rod 2114 and the limiting cylinder 2115, the rotation tendency of the tightening member 22 is offset, and the tightening member 22 generates a movement along the radial direction of the installation cylinder 41, so as to be able to clamp or release the engine injector.

[0036] The engine injector assembly equipment 100 of this embodiment can flexibly control the clamping force between the tightening members 22 by the forward and reverse rotation of the first motor 2111, so as to be applicable to the adaptive positioning of engine injectors of different sizes. Moreover, the screw drive has a self-locking characteristic, and the tightening member 22 can maintain the clamping state after the first motor 2111 stops, avoiding the engine injector from slipping. By integrating the first motor 2111 into the installation box 2116, the first motor 2111 can be protected by the installation box 2116, and a modular setting can be formed, so as to facilitate the disassembly and replacement of the first motor 2111 and the installation box 2116.

[0037] In addition, the movement of the tightening member 22 can be guided by the first limiting rod 2114 and the limiting cylinder 2115, so that the movement of the tightening member 22 is more accurate.

[0038] Combined Figure 1 , Figure 2 , Figure 3 and Figure 10 As shown in, in some embodiments, the driving assembly 21 further includes a second motor 212, a rotating gear 213 and a rotating ring 214. The rotating gear 213 is sleeved outside the rotating ring 214. The rotating ring 214 is connected to the mounting box 2116 of each driving member 211, and the second motor 212 is drivingly connected to the rotating gear 213.

[0039] The second motor 212 and the rotating gear 213 can be drivingly connected by meshing of gears or a gear set, or can be drivingly connected according to other driving connection methods well known to those skilled in the art.

[0040] It should be noted that Figure 10 the connection structure in the middle part of the rotating ring 214 is hidden to make the position relationship of each component more intuitively and concisely shown in the drawings.

[0041] When driving the tightening member 22 to move around the vertical direction a, the second motor 212 serves as a power source to provide torque. The rotating gear 213 is drivingly connected to the second motor 212 to transmit the rotational movement of the second motor 212 to the rotating ring 214. The rotating ring 214 is connected to the mounting box 2116 of the driving member 211 to drive each driving member 211 to rotate synchronously, thereby driving the tightening member 22 to rotate.

[0042] The synchronous rotation of multiple driving members 211 can be controlled by the second motor 212, improving the action consistency of each driving member 211. The cooperative design of the rotating gear 213 and the rotating ring 214 can reduce the floor space, which is beneficial to the miniaturization of the engine injector assembly equipment 100 in this embodiment. As an intermediate transmission member, the rotating ring 214 can evenly distribute the torque of the second motor 212 to each driving member 211, reducing the probability of uneven force on a single driving member 211. By controlling the second motor 212, the movement of multiple driving members 211 can be controlled, thereby reducing the control difficulty.

[0043] In some specific embodiments, a connecting portion is provided inside the rotating ring 214. The connecting portion is connected to the rotating ring 214 and is rotatably connected to the mounting seat 215.

[0044] The cooperation between the connecting portion and the mounting seat 215 enables the rotating ring 214 to obtain stable support and improves the installation stability of the rotating ring 214.

[0045] CombinedFigures 1 to 7 As shown, in some embodiments, the driving assembly 21 further includes a mounting base 215. The second motor 212 is disposed on the mounting base 215, and the rotating gear 213 is rotatably disposed on the mounting base 215. The adjusting device 30 includes a second limiting rod 31, a mounting plate 32, a third motor 33, and a second threaded rod 34. Both the second limiting rod 31 and the second threaded rod 34 extend along the first horizontal direction b. The third motor 33 is mounted on the mounting plate 32. A part of the second threaded rod 34 is in transmission connection with the third motor 33, and another part of the second threaded rod 34 is threadedly connected to the mounting base 215 in a manner capable of moving along the first horizontal direction b. A part of the second limiting rod 31 is connected to the mounting plate 32, and another part of the second limiting rod 31 is disposed on the mounting base 215 in a manner capable of moving along the first horizontal direction b.

[0046] It should be noted that Figures 1 to 7 only an exemplary possible implementation manner of the transmission connection of the third motor 33 is schematically shown. Those skilled in the art can reasonably select the specific form of the transmission connection according to the actual situation. The embodiments of the present application do not limit the form of the transmission connection of the third motor 33.

[0047] The third motor 33 drives the second threaded rod 34 to rotate, and the mounting base 215 has a tendency to rotate. Under the limiting action of the second limiting rod 31, the rotation tendency of the mounting base 215 is offset, and the mounting base 215 generates a movement along the first horizontal direction b. Through the movement of the mounting base 215, the components disposed on the mounting base 215 can be driven to move, so as to adjust the position of the tightening member 22 in the first horizontal direction b.

[0048] In the engine injector assembly device 100 of the embodiments of the present application, the second threaded rod 34 is used for transmission to drive the displacement of the mounting base 215. Thus, by controlling the third motor 33, the position of the mounting base 215 in the first horizontal direction b can be accurately adjusted.

[0049] The sliding fit between the second limiting rod 31 and the mounting base 215 can guide the movement of the mounting base 215, thereby improving the accuracy of the movement of the mounting base 215.

[0050] Combined with Figures 1 to 8 As shown, in some embodiments, the adjusting device 30 further includes a plurality of telescopic rods 35. The plurality of telescopic rods 35 are sequentially arranged at intervals along the second horizontal direction c. Each telescopic rod 35 extends along the vertical direction a. One end of each telescopic rod 35 is connected to the base 10, and the other end of each telescopic rod 35 is connected to the mounting plate 32. The first horizontal direction b and the second horizontal direction c are perpendicular to each other.

[0051] A plurality of telescopic rods 35 are sequentially spaced along the second horizontal direction c, so as to effectively support the mounting plate 32, thereby increasing the stability of the mounting plate 32.

[0052] By extending and shortening the telescopic rod 35, the position of the mounting plate 32 in the vertical direction a can be changed, so that the position of the tightening device 20 in the vertical direction a can be adjusted, and further the tightening member 22 can adapt to engine injectors of more size types.

[0053] In some alternative embodiments, each telescopic rod 35 is connected to a synchronous controller, and the synchronous controller is used to control the telescopic strokes of each telescopic rod 35 to be the same or similar, so that the movement of the mounting plate 32 can be smoother, and further the movement of the tightening device 20 can be more stable.

[0054] As some examples, the telescopic rod 35 is a pneumatic telescopic rod driven by compressed air, and the synchronous controller is a pneumatic flow divider valve. By distributing the compressed air through the pneumatic flow divider valve, the amount of compressed air flowing into or out of each pneumatic telescopic rod is equal or approximately equal, so that the telescopic strokes of each telescopic rod 35 are the same or similar.

[0055] As some other examples, the telescopic rod 35 is a hydraulic telescopic rod driven by hydraulic oil, and the synchronous controller is a hydraulic oil flow divider valve. By distributing the hydraulic oil through the hydraulic oil flow divider valve, the amount of hydraulic oil flowing into or out of each hydraulic telescopic rod is equal or approximately equal, so that the telescopic formations of each telescopic rod 35 are the same or similar.

[0056] As some other examples, the telescopic rod 35 is an electric push rod, and both the synchronous controller and the driving device are servo motors. Each telescopic rod 35 is synchronously driven by the servo motor, so that the telescopic strokes of each telescopic rod 35 are the same or similar.

[0057] Combined with Figure 8 and Figure 9As shown, in some embodiments, the push plate assembly 43 includes a push plate 431, a third threaded rod 432, a second threaded barrel 433, and a fourth motor 434. The installation assembly 42 includes a mounting member 421 and a third limiting rod 422. The third threaded rod 432, the third limiting rod 422, and the second threaded barrel 433 all extend along the radial direction of the installation cylinder 41. The push plate 431 is arranged in the installation cylinder 41 in a manner capable of moving along the radial direction of the installation cylinder 41. The fourth motor 434 is installed on the mounting member 421, and the mounting member 421 is arranged on the base 10. One of the third threaded rod 432 and the second threaded barrel 433 penetrates through the outer wall of the installation cylinder 41 and is connected to the push plate 431. The other of the third threaded rod 432 and the second threaded barrel 433 is in transmission connection with the fourth motor 434. The second threaded barrel 433 is sleeved on the third threaded rod 432 in a manner capable of moving along the radial direction of the installation cylinder 41 and is threadedly connected to the third threaded rod 432. One end of the third limiting rod 422 is connected to the mounting member 421, and the other end of the third limiting rod 422 is connected to the installation cylinder 41.

[0058] It should be noted that Figure 8 and Figure 9 only exemplarily shows a possible implementation manner of the transmission connection of the fourth motor 434. Those skilled in the art can reasonably select the specific form of the transmission connection according to the actual situation. The embodiments of the present application do not limit the specific form of the transmission connection of the fourth motor 434.

[0059] Under the action of the fourth motor 434, the third threaded rod 432 rotates relative to the second threaded barrel 433, and the push plate 431 has a tendency to rotate. Under the limiting action of the third limiting rod 422, the rotation tendency of the push plate 431 is offset, and the push plate 431 generates a movement along the radial direction of the installation cylinder 41, so as to cooperate with the installation cylinder 41 to clamp or release the engine injector.

[0060] By driving the third threaded rod 432 and the second threaded barrel 433 through the fourth motor 434, the clamping force on the engine injector can be accurately adjusted.

[0061] As Figure 3 shown, in some embodiments, the engine injector assembly equipment 100 further includes a rotating device 50. The rotating device 50 is arranged on the base 10. The rotating device 50 is connected to the mounting member 421 and is used to drive the rotating device 50 to rotate around the vertical direction a. The installation device 40 includes a plurality of installation cylinders 41 and a plurality of push plate assemblies 43. The plurality of installation cylinders 41 and the plurality of push plate assemblies 43 are arranged in one-to-one correspondence. At least one installation cylinder 41 is located on the first side of the mounting member 421, and at least one other installation cylinder 41 is located on the second side of the mounting member 421. The first side and the second side are adjacent or opposite.

[0062] At least one mounting cylinder 41 is located on the first side of the mounting member 421, and at least one other mounting cylinder 41 is located on the second side of the mounting member 421, so that the operator can select the mounting cylinder 41 in a favorable position to install the engine injector. Thus, the operator does not need to move frequently or adjust the posture. The target mounting cylinder 41 is rotated to the optimal operation position through the rotating device 50, the time for taking and placing the injector is shortened, and further the efficiency of installing the second end of the engine injector can be improved.

[0063] As Figure 3 shown, in some embodiments, the rotating device 50 includes a fifth motor 51, a rotating cylinder 52 and a linkage gear 53. The fifth motor 51 is installed on the base 10. The linkage gear 53 is sleeved on the rotating cylinder 52 and is in transmission connection with the fifth motor 51. The rotating cylinder 52 extends along the vertical direction a and is connected to the mounting member 421 in the vertical direction a.

[0064] It should be noted that Figure 3 only an exemplary possible implementation manner of the transmission connection of the fifth motor 51 is schematically shown. Those skilled in the art can reasonably select the specific form of the transmission connection according to the actual situation. The embodiments of the present application do not limit the specific form of the transmission connection of the fifth motor 51.

[0065] Through the fifth motor 51 and the linkage gear 53, the rotating cylinder 52 can be accurately driven to move to a suitable position, thereby reducing the error in the process of tightening the engine injector.

[0066] As Figure 10 shown, in some embodiments, a plurality of anti-slip blocks 44 are provided on the outer wall surface of the tightening member 22.

[0067] Through the anti-slip blocks 44, the friction between the tightening member 22 and the engine injector can be increased, the probability of slipping when the tightening member 22 screws the engine injector can be reduced, and thus the screwing effect on the engine injector can be increased.

[0068] Figure 11 This is a flowchart of the engine injector assembly method according to the embodiments of the present application.

The engine injector assembly method includes: S100. Place the engine injector in the mounting cylinder, start the push plate assembly, and make the push plate assembly and the mounting cylinder jointly abut against the second end of the engine injector; S200. Control the adjusting device to adjust the position of the tightening member, and make the position of the tightening member correspond to the mounting cylinder in the vertical direction; S300, control the driving component to drive the tightening member to approach each other, and make the tightening member clamp the first end of the engine injector; S400, control the driving component to drive the tightening member to rotate around the vertical direction, and make the tightening member tighten the engine injector.

[0070] The engine injector assembly method of the present application can automatically tighten the engine injector, thereby improving the assembly efficiency of the engine injector. Moreover, the engine injector assembly method of the present application can more precisely adjust the position and tightening force of the engine injector by adjusting the position of the tightening member through the adjusting device, driving the tightening member to clamp the engine injector through the driving component, and driving the tightening member to tighten through the driving component, so as to reduce the error in the engine injector assembly process and further improve the assembly quality of the engine injector.

[0071] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an" and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing" and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless explicitly stated as an order of performance. It should also be understood that additional or alternative steps may be used.

[0072] Although the terms first, second, third, etc. may be used in this document to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as a second element, component, region, layer, or section without departing from the teachings of the example embodiments. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0073] For ease of description, spatially relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatially relative relationship terms are intended to include different orientations of the device during use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure rotates, then an element described as "below" or "beneath" another element or feature will subsequently be oriented as "above" or "over" the other element or feature. Thus, the example term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0074] In the description of the application, the orientation or positional relationship indicated by technical terms such as "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", "height direction", "first direction", "second direction", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed, operated or used in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of the present application.

[0075] In the present application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium. It may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0076] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
