However, the installation connection between the actuator and the turbocharger is relatively cumbersome, and the calibration process is not convenient enough. Moreover, the turbocharger is relatively large in size, occupying a large space and being inconvenient to carry, and thus it is also not convenient for on-site calibration of the actuator.

[0003] The above content is only used to assist in understanding the technical solution of the invention, and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main object of the present invention is to propose a calibration tool, aiming to solve the technical problem that some existing turbocharged electronic control actuators need to be installed on the turbocharger for calibration, and the calibration process is not convenient enough.

[0005] To achieve the above object, the calibration tool proposed by the present invention is used for angle calibration of a turbocharger actuator, and includes a mounting base, a rotating member, a first calibration assembly, and a second calibration assembly. The mounting base has a first mounting surface and a second mounting surface facing away from each other, and the second mounting surface is used for mounting the actuator to be calibrated. The rotating member is rotatably mounted on the mounting base, and has a connection end extending out of the first mounting surface and an engagement end extending out of the second mounting surface, and the engagement end is used for engaging with the output gear of the actuator. The first calibration assembly includes a first calibration member and a second calibration member respectively extending along the radial direction of the rotating member, and a calibration angle is formed between the first calibration member and the second calibration member. The second calibration assembly is disposed within the calibration angle range, and one of the first calibration assembly and the second calibration assembly is connected to the connection end of the rotating member, and the other is mounted on the first mounting surface of the mounting base.

[0006] In one embodiment, at least one of the first calibration member and the second calibration member can rotate around the central axis of the rotating member, so that the calibration angle is adjustable.

[0007] In one embodiment, the first calibration assembly further includes a first annular block and a second annular block, the first annular block and the second annular block are respectively mounted on the first mounting surface and are both coaxially arranged with the rotating member; the first calibration member is connected to the first annular block, the second calibration member is connected to the second annular block, and at least one of the first annular block and the second annular block can rotate around the central axis of the rotating member.

[0008] In one embodiment, a first bearing hole is further provided on the first calibration piece, and a first bearing installed in the bearing hole, and an end of the rotating piece is rotatably installed in the first bearing.

[0009] In one embodiment, the second annular block surrounds the first annular block, and an inner peripheral surface of the second annular block is in contact with an outer peripheral surface of the first annular block.

[0010] In one embodiment, the first annular block is further penetrated with a first kidney-shaped hole, the first kidney-shaped hole extends along a circumferential direction of the first annular block, and a plurality of first screw holes are further provided at positions corresponding to the first kidney-shaped hole on the first mounting surface, and the plurality of first screw holes are arranged at intervals along the circumferential direction of the first annular block; and / or, the second annular block is further penetrated with a second kidney-shaped hole, the second kidney-shaped hole extends along a circumferential direction of the second annular block, and a plurality of second screw holes are further provided at positions corresponding to the second kidney-shaped hole on the first mounting surface, and the plurality of second screw holes are arranged at intervals along the circumferential direction of the second annular block.

[0015] The calibration tooling of the present invention can replace a turbocharger to perform angle calibration on a turbocharged actuator. When the actuator needs to be angle-calibrated, only its mounting seat needs to be positioned on the actuator so that the meshing end of its rotating piece meshes with the output gear of the actuator, and then the calibration can be started. Compared with the relatively complex installation connection between the turbocharger and the actuator, the installation and positioning of the calibration tooling of the present invention on the actuator is simpler. As long as the meshing end of the rotating piece can mesh with the output gear of the actuator, the calibration of the turbocharged actuator is made simpler and more convenient, effectively improving the detection efficiency.

[0035] The realization of the purpose, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0036] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0037] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0038] Please refer to Figure 1 , the turbocharger actuator 20 (hereinafter simply referred to as "actuator 20") mainly includes a housing 21, a drive motor installed in the housing 21, and an output gear 22 connected to the drive motor. The output gear 22 extends outside the housing 21 of the actuator 20 and is used to connect to a bypass valve in the turbocharger, and thus can control the boost size of the turbocharger by driving the bypass valve. And there is a corresponding calibration angle for each bypass valve in the turbocharger so that the turbocharger can be in the best working state.

[0039] Therefore, after production, the actuator 20 needs to be uniformly calibrated to ensure that its rotation angle meets the requirements. The existing calibration methods generally directly install and connect the actuator 20 to the turbocharger for calibration, but such a calibration method is rather cumbersome and the calibration process is not convenient. The present invention proposes a calibration tooling 10 for calibrating the turbocharged actuator 20 to make the calibration process of the actuator 20 more convenient.

[0040] In the embodiment of the present invention, as Figures 2 to 4 shown, the calibration tooling 10 includes a mounting base 30, a rotating member 40, a first calibration assembly 50 and a second calibration assembly 60. Among them, the mounting base 30 has a rectangular block structure with a first mounting surface 31 and a second mounting surface 32 facing away from each other, and the second mounting surface 32 is used for mounting the actuator 20 to be calibrated. Specifically, please refer to Figure 9 and Figure 10 , the second mounting surface 32 is provided with a first positioning hole 321, and the first positioning hole 321 is used to position the output gear 22 of the actuator 20, and there are various specific ways for the first positioning hole 321 to position the output gear 22 of the actuator 20.

[0041] For example, the size and depth of the first positioning hole 321 can accommodate a part of the output gear 22, so that the output gear 22 of the actuator 20 can be prevented from moving in all directions, and the meshing between the output gear 22 and the rotating member 40 is not affected.

[0042] Also, for example, the size of the first positioning hole 321 can be rotationally connected to the rotating shaft of the output gear 22, thereby realizing the positioning of the entire output gear 22.

[0043] Also, for example, in an embodiment, please refer to Figure 1 and Figure 10 , a third bearing 221 is installed at the end of the output gear 22, and the size of the first positioning hole 321 is adapted to the third bearing 221. In this embodiment, when the calibration tooling 10 needs to be installed on the actuator 20, the first positioning hole 321 is sleeved outside the third bearing 221 on the output gear 22. In this way, the positional relationship between the actuator 20 and the calibration tooling 10 can be quickly positioned, and the meshing end 42 between the output gear 22 of the actuator 20 and the rotating member 40 can always be kept meshed to avoid disengagement.

[0044] Of course, in another embodiment, please refer to Figures 9 to 11, to make the positioning of the calibration tooling 10 on the actuator 20 faster and more stable, a second positioning hole 322 is further provided on the second mounting surface 32, and the second positioning hole 322 is used to position the calibration tooling 10 on the actuator 20. That is, in addition to positioning the output gear 22 of the actuator 20 through the first positioning hole 321, in this embodiment, the entire calibration tooling 10 is quickly positioned through the second positioning hole 322.

[0045] Specifically, the second positioning hole 322 can be designed for the protruding structure on the actuator 20. Then, when positioning the calibration tooling 10 on the actuator 20, the second positioning hole 322 can be sleeved on the corresponding protruding structure, and then cooperate with the first positioning hole 321 to achieve the quick positioning of the entire calibration tooling 10. And through the mutual cooperation of the first positioning hole 321 and the second positioning hole 322, the positioning of the entire calibration tooling 10 is more stable.

[0046] Of course, in order to enable the calibration tooling 10 to be used for calibrating actuators 20 with different structures and types, in one embodiment, as Figure 6 and Figure 11 shown, the calibration tooling 10 further includes a second threaded fastener 70, and the second threaded fastener 70 is used to be fixed on the actuator 20 and has a positioning cap 71 adapted to the second positioning hole 322. Specifically, when positioning the calibration tooling 10 on the actuator 20, the second threaded fastener 70 can be first fixed on the actuator 20, and the positioning cap 71 of the second threaded fastener 70 protrudes from the outer surface of the actuator 20. Then, the second positioning hole 322 on the mounting seat 30 is correspondingly sleeved outside the positioning cap 71, and the positioning of the calibration tooling 10 on the actuator 20 can be achieved.

[0047] It can be understood that the actuator 20 generally has threaded holes for connecting with the turbocharger. The second threaded fastener 70 enables the calibration tooling 10 to be conveniently positioned on actuators 20 with different structures and types, and thus has a wider application range.

[0048] Among them, in order to make the positioning and installation of the calibration tooling 10 more balanced and stable, multiple second positioning holes 322 and second threaded fasteners 70 can be provided respectively. For example, in one embodiment, two second positioning holes 322 are provided, and the two second positioning holes 322 extend along the width direction or the length direction of the mounting seat 30.

[0049] Or, after the calibration tooling 10 is positioned, the mounting seat 30 can be connected to the second threaded fastener 70 to further ensure the installation stability of the calibration tooling 10. For example, in one embodiment, as Figure 11As shown, an internal thread is further provided in the positioning cap 71. The calibration tooling 10 further includes a third threaded fastener 80, and the third threaded fastener 80 is used to fixedly connect the mounting seat 30 to the positioning cap 71. Specifically, in this embodiment, a through hole corresponding to and communicating with the second positioning hole 322 is provided on the first mounting surface 31 of the mounting seat 30. The third threaded fastener 80 passes through this through hole and is connected to the second threaded fastener 70, thereby realizing the fixed connection between the mounting seat 30 and the second threaded fastener 70, and improving the installation stability of the calibration tooling 10 on the actuator 20.

[0050] The rotating member 40 is rotatably mounted on the mounting seat 30, and has a connecting end 41 extending out of the first mounting surface 31 and an engaging end 42 extending out of the second mounting surface 32. The engaging end 42 is used to engage with the output gear 22 of the actuator 20. Specifically, please refer to Figures 5 to 8 . The mounting seat 30 is provided with a second bearing hole 33, and a second bearing 34 is mounted in the second bearing hole 33. The rotating member 40 is rotatably mounted in the second bearing 34, and both ends thereof extend out of the mounting seat 30 respectively.

[0051] One end of the rotating member 40 extends out of the second mounting surface 32 of the mounting seat 30 and is formed with a gear structure for engaging with the output gear 22 of the actuator 20. Thus, when the output gear 22 of the actuator 20 rotates, the rotating member 40 can be driven to rotate together. The other end of the rotating member 40 extends out of the first mounting surface 31 of the mounting seat 30 and is used to connect with the first calibration assembly 50 or the second calibration assembly 60 to drive the first calibration assembly 50 or the second calibration assembly 60 to rotate, thereby realizing the calibration of the actuator 20.

[0052] Specifically, the first calibration assembly 50 includes a first calibration member 51 and a second calibration member 52 respectively extending along the radial direction of the rotating member 40. A calibration angle 53 is formed between the first calibration member 51 and the second calibration member 52 (for the calibration angle, please refer to Figure 16 ). Among them, the sizes, shapes, etc. of the first calibration member 51 and the second calibration member 52 are not specifically limited herein. For example, they can be in the form of strips, rods, long block-shaped structures, etc., as long as they can be arranged at an angle to form the calibration angle 53. The first calibration member 51 and the second calibration member 52 can be connected to the rotating member 40 and rotate together with the rotating member 40, or can be connected to the mounting seat 30 and fixed relative to the mounting seat 30.

[0053] The second calibration component 60 is disposed within the calibration angle range of 53°. One of the first calibration component 50 and the second calibration component 60 is connected to the connection end 41 of the rotating member 40, and the other is mounted on the first mounting surface 31 of the mounting base 30. It should be noted that taking the connection between the second calibration component 60 and the connection end 41 of the rotating member 40 as an example, the fact that the second calibration component 60 is disposed within the calibration angle range of 53° means that when the rotating member 40 drives the second calibration component 60 to rotate, the second calibration component 60 can be blocked by the first calibration member 51 and cannot continue to rotate, and can also be blocked by the second calibration member 52 and cannot continue to rotate.

[0054] Therefore, still taking the connection between the second calibration component 60 and the connection end 41 of the rotating member 40 as an example, when calibrating the actuator 20, first determine whether the calibration angle 53 formed between the first calibration member 51 and the second calibration member 52 is the required angle. Then position the calibration tooling 10 on the actuator 20 and make the second calibration component 60 abut against the first calibration member 51. Then start the actuator 20, and drive the second calibration component 60 to rotate through the actuator 20 until the second calibration component 60 abuts against the second calibration member 52, that is, the calibration of the actuator 20 is completed.

[0055] In summary, it can be understood that the calibration tooling 10 of the present invention can replace the turbocharger to perform angle calibration on the turbocharged actuator 20. When it is necessary to perform angle calibration on the actuator 20, only need to position its mounting base 30 on the actuator 20 so that the meshing end 42 of its rotating member 40 meshes with the output gear 22 of the actuator 20, and then the calibration can be started. Compared with the relatively complex installation connection between the turbocharger and the actuator 20, the installation and positioning of the calibration tooling 10 of the present invention on the actuator 20 is simpler. As long as the meshing end 42 of the rotating member 40 can mesh with the output gear 22 of the actuator 20, thereby making the calibration of the turbocharged actuator 20 simpler and more convenient, and effectively improving the detection efficiency.

[0056] In one embodiment, please refer to Figure 5 and Figure 8 , at least one of the first calibration member 51 and the second calibration member 52 can rotate around the central axis of the rotating member 40 so that the calibration angle 53 is adjustable. For example, it can be that the first calibration member 51 can rotate around the central axis of the rotating member 40, and the second calibration member 52 is fixed relative to the mounting base 30. It can also be that the second calibration member 52 can rotate around the central axis of the rotating member 40, and the first calibration member 51 is fixed relative to the mounting base 30. It can also be that both the first calibration member 51 and the second calibration member 52 can rotate around the central axis of the rotating member 40. Specifically, it can be selected according to needs and is not limited here.

[0057] It can be understood that the adjustable calibration angle 53 enables the calibration tooling 10 to replace various different models of turbochargers, and thus calibrate different models of actuators 20, with stronger versatility and a more convenient calibration process.

[0058] In one embodiment, please refer to Figure 5 、 Figure 14 and Figure 15 The first calibration component 50 further includes a first annular block 54 and a second annular block 55. The first annular block 54 and the second annular block 55 are respectively installed on the first mounting surface 31, and are both coaxially arranged with the rotating member 40. The first calibration member 51 is connected to the first annular block 54, and the second calibration member 52 is connected to the second annular block 55. At least one of the first annular block 54 and the second annular block 55 can rotate around the central axis of the rotating member 40.

[0059] That is to say, the first calibration component 50 is installed on the first mounting surface 31 of the mounting seat 30, and the connection end 41 of the second calibration component 60 is connected to the rotating member 40. When it is necessary to adjust the calibration angle 53, just rotate the first annular block 54 or the second annular block 55, making the adjustment of the calibration angle 53 very convenient and fast.

[0060] In one embodiment, please refer to Figure 8 and Figure 14 The first calibration member 51 is also provided with a first bearing hole 511 for the first bearing 512, and the first bearing 512 is installed in the bearing hole. The end of the rotating member 40 is rotatably installed in the first bearing 512. It can be understood that such a setting can enhance the coaxiality between the first annular block 54 and the rotating member 40, and ensure the accuracy of the calibration angle 53. Of course, the second calibration member 52 can also be provided with a bearing hole and a bearing like the first calibration member 51. At this time, the first calibration member 51 and the second calibration can be arranged at different heights, so as to be able to be simultaneously connected to the rotating member 40 by bearings, ensuring the coaxiality among the first calibration member 51, the second calibration member 52, and the rotating member 40.

[0061] Or, in one embodiment, as shown in Figure 7 , the second annular block 55 surrounds the first annular block 54, and the inner peripheral surface of the second annular block 55 is in contact with the outer peripheral surface of the first annular block 54. This not only ensures the coaxiality among the first calibration member 51, the second calibration member 52, and the rotating member 40, but also makes the overall structure of the calibration tooling simpler, more compact, and easier to assemble.

[0062] In one embodiment, as shown in Figure 9 and Figure 14As shown, the first annular block 54 is also penetrated with a first waist-shaped hole 541. The first waist-shaped hole 541 extends along the circumferential direction of the first annular block 54. At the position corresponding to the first waist-shaped hole 541 on the first mounting surface 31, a plurality of first screw holes 311 are further provided. The plurality of first screw holes 311 are arranged at intervals along the circumferential direction of the first annular block 54. It can be understood that by providing the first waist-shaped hole 541 and the first screw holes 311, not only can the first annular block 54 and the mounting base 30 be conveniently fixed and connected by screws, but also when it is necessary to rotate the first annular block 54 to adjust the calibration angle 53, the situation where the first annular block 54 and the mounting base 30 cannot be continuously fixed and connected can be avoided.

[0063] In one embodiment, as Figure 9 and Figure 15 shown, the second annular block 55 is also penetrated with a second waist-shaped hole 551. The second waist-shaped hole 551 extends along the circumferential direction of the second annular block 55. At the position corresponding to the second waist-shaped hole 551 on the first mounting surface 31, a plurality of second screw holes 312 are further provided. The plurality of second screw holes 312 are arranged at intervals along the circumferential direction of the second annular block 55. Similarly, it can be understood that by providing the second waist-shaped hole 551 and the second screw holes 312, not only can the second annular block 55 and the mounting base 30 be conveniently fixed and connected by screws, but also when it is necessary to rotate the second annular block 55 to adjust the calibration angle 53, the situation where the second annular block 55 and the mounting base 30 cannot be continuously fixed and connected can be avoided.

[0064] In one embodiment, as Figure 14 and Figure 15 shown, a plurality of the first waist-shaped holes 541 and the second waist-shaped holes 551 are respectively provided. The plurality of first waist-shaped holes 541 are arranged at intervals along the circumferential direction of the first annular block 54, and the plurality of second waist-shaped holes 551 are arranged at intervals along the circumferential direction of the second annular block 55. In this way, the adjustable range of the calibration angle 53 is larger, and thus the versatility of the calibration tooling 10 is stronger.

[0065] In one embodiment, the first annular block 54 and the first calibration member 51 are integrally formed. In this way, not only can the connection stability of the first calibration member 51 on the first annular block 54 be ensured, but also the assembly process of the calibration tooling 10 is simplified.

[0066] In one embodiment, the second annular block 55 and the second calibration member 52 are integrally formed. In this way, not only can the connection stability of the second calibration member 52 on the second annular block 55 be ensured, but also the assembly process of the calibration tooling 10 is simplified.

[0067] In one embodiment, as Figure 12 and Figure 13As shown, the second calibration component 60 includes a third calibration piece 61. The third calibration piece 61 extends parallel to the central axis of the rotating piece 40 and is connected to the connection end 41 of the rotating piece 40. Specifically, in this embodiment, the third calibration piece 61 has a rod-shaped structure and is spaced from the central axis of the rotating piece 40 when connected to the connection end 41 of the rotating piece 40. In this way, the rotating piece 40 can easily drive the second calibration component 60 to rotate within the calibration angle range of 53°.

[0068] The third calibration piece 61 can be connected to the rotating piece 40 through an intermediate connecting piece, or the third calibration can partially extend in the radial direction of the rotating piece 40 and then extend onto the rotating piece 40 and be connected to the rotating piece 40.

[0069] In one embodiment, as Figure 12 and Figure 13 shown, a connection disk 411 is formed at the connection end 41 of the rotating piece 40. The connection disk 411 is coaxial with the rotating piece 40 and is provided with an installation hole spaced from its center. The third calibration piece 61 is fixed at the installation hole. Such a setting makes the connection between the third calibration piece 61 and the rotating piece 40 more stable. And the connection disk 411 also facilitates the positioning of the first annular block 54 and the second annular block 55.

[0070] In one embodiment, as Figure 12 and Figure 13 shown, the installation hole penetrates through the connection disk 411. The second calibration component 60 further includes a first threaded fastener 62. One end of the third calibration piece 61 passes through the installation hole and is threadedly connected to the first threaded fastener 62. It can be understood that by fixing the third calibration piece 61 on the connection disk 411 through the first threaded fastener 62, the situation of tilting or falling off when the third calibration piece 61 comes into contact with the first calibration or second calibration piece 52 can be avoided, improving the reliability of the calibration tooling 10.

[0071] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
