[0041] The following describes exemplary embodiments of the present application in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0042] The engine injector is a key component of the fuel injection system. The engine injector is used to accurately spray fuel into the engine combustion chamber, mixing it with air to form a combustible mixture, allowing the engine to run normally.

[0043] 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.

[0044] However, the engine injector in the prior art is assembled manually, and the assembly efficiency is low.

[0045] 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.

[0046] 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.

[0047] The following describes an engine injector assembly device 100 and an engine injector assembly method according to an embodiment of the present application with reference to the accompanying drawings.

[0048] Combine 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 adjustment device 30, and a mounting device 40. The tightening device 20 includes a drive assembly 21 and at least two tightening members 22. The at least two tightening members 22 operate synchronously. The drive 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 them closer together, or to drive the at least two tightening members 22 to release the first end by moving them away from each other, and to drive the tightening members 22 to rotate about a vertical direction a.

[0049] Adjustment device 30 is connected to base 10 and is in driving connection with drive assembly 21, and is used to adjust the position of tightening member 22. Mounting device 40 includes mounting cylinder 41, mounting assembly 42, and push plate assembly 43. Mounting cylinder 41 is connected to mounting assembly 42 and is used to place the second end of the engine injector. Mounting assembly 42 is provided on base 10, and push plate assembly 43 is provided on mounting assembly 42. Push plate assembly 43 is provided on mounting cylinder 41 in a manner that allows radial movement of mounting cylinder 41, and is used to abut the second end of mounting cylinder 41 together with mounting cylinder 41 or separate from the second end.

[0050] 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.

[0051] When the engine injector needs to be tightened, the engine injector is placed in the mounting cylinder 41, and the push plate assembly 43 is driven to move the push plate assembly 43 along the radial direction of the mounting cylinder 41 toward the engine injector, so that the push plate assembly 43 and the mounting cylinder 41 are jointly in contact with the engine injector, and then the second end of the engine injector is fixed through the joint action of the push plate assembly 43 and the mounting cylinder 41.

[0052] The position of the driving assembly 21 is adjusted by the adjusting device 30, thereby adjusting the position of the tightening member 22, so that the position of the tightening member 22 is opposite to the mounting cylinder 41 in the vertical direction a, and the driving assembly 21 controls the tightening member 22 to approach, so that the tightening members 22 approach each other synchronously, and then under the joint action of multiple tightening members 22, the first end of the engine injector is clamped by multiple tightening members 22.

[0053] The plurality of tightening members 22 are rotated about the vertical direction a by the driving assembly 21, thereby rotating 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.

[0054] After tightening the engine injector, the tightening members 22 are controlled to move away from each other by the driving assembly 21, thereby releasing the first end of the engine injector, and the push plate assembly 43 is driven to move the push plate assembly 43 along the radial direction of the mounting cylinder 41 away from the engine injector, thereby releasing the second end of the engine injector, thereby enabling the engine injector to be removed.

[0055] The engine injector assembly device 100 of the present application can automatically tighten the engine injector, thereby improving the assembly efficiency of the engine injector. Furthermore, the engine injector assembly device 100 of the present application adjusts the position of the tightening member 22 via the adjustment device 30, drives the tightening member 22 to clamp the engine injector via the drive assembly 21, and drives the tightening member 22 to tighten via the drive assembly 21. This allows for more precise adjustment of the position and tightening force of the engine injector, thereby reducing errors during the engine injector assembly process and improving the assembly quality of the engine injector.

[0056] like Figure 10 As shown, in some embodiments, the tightening member 22 is arranged in sequence around the vertical direction a, and the driving assembly 21 includes at least two driving components 211. The driving components 211 are arranged in a one-to-one correspondence with the tightening member 22. The driving component 211 includes a first motor 2111, a first threaded rod 2112, a first threaded barrel 2113, a first limiting rod 2114, a limiting barrel 2115 and an installation box 2116. The first threaded rod 2112, the first threaded barrel 2113, the first limiting rod 2114 and the limiting barrel 2115 all extend along the radial direction of the installation barrel 41. The first motor 2111 is installed in the installation box 2116. The first threaded rod 2112 and the first threaded barrel 2113 One of the threaded cylinders 2113 is passed through the mounting box 2116 and is connected to the first motor 2111 in transmission. The first threaded rod 2112 and the other of the first threaded cylinder 2113 are connected to the tightening member 22. The first threaded cylinder 2113 is sleeved on the first threaded rod 2112 in a manner that it can move along the radial direction of the mounting cylinder 41 and is threadedly connected to the first threaded rod 2112. The mounting box 2116 and one of the tightening member 22 are connected to the first limiting rod 2114. The mounting box 2116 and the other of the tightening member 22 are connected to the limiting cylinder 2115. The first limiting rod 2114 is slidably arranged in the limiting cylinder 2115.

[0057] The first motor 2111 can be connected to one of the first threaded rod 2112 and the first threaded barrel 2113 through meshing of gears or a gear set, or through other transmission connection methods known to those skilled in the art.

[0058] 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 movement in the radial direction of the mounting cylinder 41, thereby being able to clamp or release the engine injector.

[0059] The engine injector assembly device 100 of this embodiment can flexibly control the clamping force between the tightening members 22 by rotating the first motor 2111 in both forward and reverse directions, thereby accommodating the adaptive positioning of engine injectors of varying sizes. Furthermore, the self-locking nature of the threaded drive ensures that the tightening members 22 remain clamped even after the first motor 2111 is shut down, preventing the engine injector from slipping. By integrating the first motor 2111 within the mounting box 2116, the mounting box 2116 protects the first motor 2111 and creates a modular design, facilitating removal and replacement of the first motor 2111 and mounting box 2116.

[0060] 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 precise.

[0061] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 10 As shown, in some embodiments, the driving assembly 21 also includes a second motor 212, a rotating gear 213 and a rotating ring 214, the rotating gear 213 is arranged outside the rotating ring 214, the rotating ring 214 is connected to the installation box 2116 of each driving component 211, and the second motor 212 is connected to the rotating gear 213 through transmission.

[0062] The second motor 212 and the rotating gear 213 can be connected to each other through the meshing of gears or gear sets, or can be connected to each other through other transmission connection methods known to those skilled in the art.

[0063] It should be noted that Figure 10 The connection structure in the middle portion of the rotating circle 214 is omitted so that the figure can more intuitively and concisely show the positional relationship of the various components.

[0064] When driving the tightening member 22 to move around the vertical direction a, the second motor 212 acts as a power source to provide torque. The rotating gear 213 is connected to the second motor 212 to transmit the rotational motion of the second motor 212 to the rotating circle 214. The rotating circle 214 is connected to the installation box 2116 of the driving component 211, driving each driving component 211 to rotate synchronously, thereby driving the tightening member 22 to rotate.

[0065] The second motor 212 can control the synchronous rotation of multiple drive components 211, thereby improving the consistency of the movement of each drive component 211. The coordinated design of the rotating gear 213 and the rotating ring 214 can reduce the floor space, thereby facilitating the miniaturization of the engine injector assembly device 100 of this embodiment. The rotating ring 214, as an intermediate transmission member, can evenly distribute the torque of the second motor 212 to each drive component 211, reducing the probability of uneven force on a single drive component 211. By controlling the second motor 212, it is possible to control the movement of multiple drive components 211, thereby reducing the difficulty of control.

[0066] In some specific embodiments, a connecting portion is provided in the rotating circle 214 , the connecting portion is connected to the rotating circle 214 , and the connecting portion is rotatably connected to the mounting seat 215 .

[0067] The cooperation between the connecting portion and the mounting seat 215 provides stable support for the rotating ring 214 , thereby improving the stability of the installation of the rotating ring 214 .

[0068] Combine Figures 1 to 7 As shown, in some embodiments, the drive assembly 21 also includes a mounting seat 215, the second motor 212 is provided on the mounting seat 215, the rotating gear 213 is rotatably provided on the mounting seat 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, the second limiting rod 31 and the second threaded rod 34 both extend along the first horizontal direction b, the third motor 33 is installed on the mounting plate 32, a portion of the second threaded rod 34 is transmission-connected to the third motor 33, and another portion of the second threaded rod 34 is threadedly connected to the mounting seat 215 in a manner that can move along the first horizontal direction b, a portion of the second limiting rod 31 is connected to the mounting plate 32, and another portion of the second limiting rod 31 is provided on the mounting seat 215 in a manner that can move along the first horizontal direction b.

[0069] It should be noted that Figures 1 to 7 The figure only illustrates a possible implementation method of the transmission connection of the third motor 33. Those skilled in the art can reasonably select the specific form of the transmission connection according to actual conditions. The embodiment of the present application does not limit the form of the transmission connection of the third motor 33.

[0070] The third motor 33 drives the second threaded rod 34 to rotate, and the mounting seat 215 has a tendency to rotate. Under the limiting action of the second limiting rod 31, the rotation tendency of the mounting seat 215 is offset, and the mounting seat 215 generates movement along the first horizontal direction b. Through the movement of the mounting seat 215, the components provided on the mounting seat 215 can be driven to move, thereby adjusting the position of the tightening member 22 in the first horizontal direction b.

[0071] The engine injector assembly device 100 of the embodiment of the present application drives the mounting seat 215 to move by the second threaded rod 34 , thereby controlling the third motor 33 to accurately adjust the position of the mounting seat 215 in the first horizontal direction b.

[0072] The second limiting rod 31 is in sliding cooperation with the mounting seat 215 , thereby being able to guide the movement of the mounting seat 215 , thereby improving the accuracy of the movement of the mounting seat 215 .

[0073] Combine Figures 1 to 8 As shown, in some embodiments, the adjusting device 30 further includes a plurality of telescopic rods 35, and the plurality of telescopic rods 35 are arranged in sequence and spaced apart 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, and the first horizontal direction b and the second horizontal direction c are perpendicular to each other.

[0074] The multiple telescopic rods 35 are spaced apart in sequence along the second horizontal direction c, so as to effectively support the mounting plate 32 and increase the stability of the mounting plate 32.

[0075] The position of the mounting plate 32 in the vertical direction a can be changed by extending and shortening the telescopic rod 35 , thereby adjusting the position of the tightening device 20 in the vertical direction a, thereby enabling the tightening member 22 to adapt to engine injectors of various sizes and types.

[0076] In some optional embodiments, each telescopic rod 35 is connected to a synchronous controller, which is used to control the telescopic stroke of each telescopic rod 35 to be the same or similar, so that the movement of the mounting plate 32 can be smoother, and the movement of the tightening device 20 can be smoother.

[0077] As some examples, the telescopic rod 35 is a pneumatic telescopic rod driven by compressed air, and the synchronization controller is a pneumatic diverter valve, which distributes the compressed air through the pneumatic diverter valve so that the amount of compressed air flowing into or out of each pneumatic telescopic rod is equal or approximately equal, so that the telescopic stroke of each telescopic rod 35 is the same or similar.

[0078] As another example, the telescopic rod 35 is a hydraulic telescopic rod driven by hydraulic oil, and the synchronization controller is a hydraulic oil diverter valve, which distributes the hydraulic oil through the hydraulic oil diverter valve so that the amount of hydraulic oil flowing into or out of each hydraulic telescopic rod is equal or approximately equal, so that the telescopic and extension forms of each telescopic rod 35 are the same or similar.

[0079] As another example, the telescopic rod 35 is an electric push rod, and the synchronous controller and the driving device are both servo motors. Each telescopic rod 35 is synchronously driven by the servo motor, so that the telescopic stroke of each telescopic rod 35 is the same or similar.

[0080] Combine Figure 8 and Figure 9 As 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 mounting 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 mounting barrel 41, the push plate 431 is arranged in the mounting barrel 41 in a manner that can move along the radial direction of the mounting barrel 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 cylinder 433 is penetrated through the outer wall of the mounting cylinder 41 and is connected to the push plate 431. The other of the third threaded rod 432 and the second threaded cylinder 433 is transmission-connected to the fourth motor 434. The second threaded cylinder 433 is sleeved on the third threaded rod 432 in a manner that it can move along the radial direction of the mounting 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 piece 421, and the other end of the third limiting rod 422 is connected to the mounting cylinder 41.

Those skilled in the art can reasonably select the specific form of the transmission connection according to actual conditions. The embodiment of the present application does not limit the specific form of the transmission connection of the fourth motor 434.

[0082] Under the action of the fourth motor 434, the third threaded rod 432 rotates relative to the second threaded cylinder 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 movement along the radial direction of the mounting cylinder 41, so that it can work together with the mounting cylinder 41 to clamp or release the engine injector.

[0083] The third threaded rod 432 and the second threaded barrel 433 are driven by the fourth motor 434, so that the clamping force on the engine injector can be accurately adjusted.

[0084] like Figure 3As shown, in some embodiments, the engine injector assembly equipment 100 also includes a rotating device 50, which is provided on the base 10, and 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, and the mounting device 40 includes a plurality of mounting cylinders 41 and a plurality of push plate assemblies 43, and the plurality of mounting cylinders 41 and the plurality of push plate assemblies 43 are arranged in a one-to-one correspondence, at least one mounting cylinder 41 is located on the first side of the mounting member 421, and at least another mounting cylinder 41 is located on the second side of the mounting member 421, and the first side and the second side are adjacent to or opposite to each other.

[0085] At least one mounting cylinder 41 is located on the first side of the mounting member 421, and at least another 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, so that the operator does not need to move or adjust the posture frequently, and the target mounting cylinder 41 is rotated to the optimal operating position through the rotating device 50, thereby shortening the time for taking and placing the injector, and thus improving the efficiency of installing the second end of the engine injector.

[0086] like Figure 3 As 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 transmission-connected to 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.

[0087] It should be noted that Figure 3 The figure only illustrates a possible implementation method of the transmission connection of the fifth motor 51. Those skilled in the art can reasonably select the specific form of the transmission connection according to actual conditions. The embodiment of the present application does not limit the specific form of the transmission connection of the fifth motor 51.

[0088] The fifth motor 51 and the linkage gear 53 can accurately drive the rotating cylinder 52 to move to a suitable position, thereby reducing the error in the process of tightening the engine injector.

[0089] like Figure 10 As shown, in some embodiments, a plurality of anti-sliding blocks 44 are provided on the outer wall surface of the tightening member 22 .

[0090] The anti-sliding block 44 can increase the friction between the tightening member 22 and the engine injector, reducing the probability of the tightening member 22 slipping when screwing the engine injector, thereby improving the screwing effect on the engine injector.

[0091] Figure 11 This is a flow chart of an engine injector assembly method according to an embodiment of the present application.

[0092] like Figure 11 As shown, the engine injector assembly method of the embodiment of the present application is applied to the engine injector assembly equipment of the above embodiment, and the engine injector assembly method includes:

[0093] S100, placing the engine injector in the mounting barrel, starting the push plate assembly, and making the push plate assembly and the mounting barrel abut against the second end of the engine injector;

[0094] S200, controlling the adjusting device to adjust the position of the tightening member so that the position of the tightening member corresponds to the mounting tube in the vertical direction;

[0095] S300, controlling the driving assembly to drive the tightening members closer to each other, and causing the tightening members to clamp the first end of the engine injector;

[0096] S400: Control the driving assembly to drive the tightening member to rotate in a vertical direction, and make the tightening member tighten the engine injector.

[0097] The engine injector assembly method of the present application can automatically tighten the engine injector, thereby improving the assembly efficiency of the engine injector. Furthermore, the engine injector assembly method of the present application adjusts the position of the tightening member via an adjustment device, drives the tightening member to clamp the engine injector via a drive assembly, and then drives the tightening member to tighten via the drive assembly. This method can more accurately adjust the position and tightening force of the engine injector, thereby reducing errors during the engine injector assembly process and further improving the assembly quality of the engine injector.

[0099] Although the terms first, second, third, etc. can be used in the text 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 can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teachings of the example embodiments. In the description of the present application, the meaning of "multiple" is at least two, for example two, three, etc., unless otherwise clearly and specifically defined.

Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is rotated, an element described as "below" or "beneath" another element or feature would then be oriented "above" or "above" the other element or feature. Thus, the example term "below" would encompass both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.

[0101] In the description of the application, the orientations or positional relationships indicated by technical terms such as "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "circumferential", "height direction", "first direction", and "second direction" are based on the orientations or positional relationships shown in the accompanying drawings.
