[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0038] like Figure 1 As shown, this is an automatic assembly device for diesel generator set parts provided in Embodiment 1 of the present invention. Embodiment 1 includes an upper frame 1, a middle frame 2, and a bottom frame 3. The upper frame 1 is slidably mounted on the middle frame 2 along the Z-axis direction, and a flipping device 4 and a tightening device 5 are installed on the upper frame 1. The tightening device 5 is slidably mounted on one end of the upper frame 1 along the Y-axis direction. Figure 5As shown, the upper frame 1 is provided with a first support beam 101 for mounting the turnover device 4, a second support beam 102 for mounting the tightening device 5, and a third support beam 103. Figure 1 As shown, the turnover device 4 moves along the X-axis direction, while the tightening device 5 moves along the Y-axis direction. When the tightening device 5 moves to both sides of the upper frame 1, the turnover device 4 and the tightening device 5 still have a spacing between the YZ plane to avoid interference between them.

[0039] Next, as shown in Figure 3 and Figure 4 , the middle frame 2 of the embodiment is slidably arranged on the bottom frame 3 along the X-axis direction, and the middle frame 2 is provided with a limiting device 6. The door plate 9 is placed on the middle frame 2 and can be limited by the limiting device 6. The turnover device 4 is slidably arranged on the upper frame 1 along the X-axis direction, and the turnover part of the turnover device 4 is provided with a suction cup device 7. The limiting device 6 is used to limit the position of the door plate 9 on the suction cup device 7 to ensure that the door plate 9 can be located at the middle position of the suction cup device 7.

[0040] Generally, two hinges are installed on the same side of a door plate 9. The traditional single hinge and single bolt tightening process will cause the remaining three hole positions of the hinge to be not completely aligned after the first bolt is installed, which requires manual support and adjustment. At the same time, after the first hinge is installed, the door plate 9 will be slightly inclined (approximately with the first hinge as the center) due to the influence of gravity, and this slight inclination will cause the bolt hole positions of the second hinge to be not completely aligned. Therefore, the tightening device 5 in the embodiment has two sleeve mounting seats 502 for aligning two hinges. The sleeve mounting seat 502 is provided with a servo motor 508 and a first power shaft 503 and a second power shaft 504 for connecting the sleeve. The output end of the servo motor 508 is power-connected to the first power shaft 503 and the second power shaft 504 through the telescopic assembly 507. The sleeve mounting seat 502 can connect the bolts through the sleeve. In the embodiment, a five-sided bolt or a six-sided bolt can be used. The deformation of the telescopic assembly 507 can change the distance between the first power shaft 503 and the second power shaft 504, so that the first power shaft 503 and the second power shaft 504 can adapt to the bolt hole positions on different hinges.

[0041] As shown in Figure 5 and Figure 6As shown, the tightening device 5 comprises a U-shaped adjusting frame 501, the upper and lower ends of the adjusting frame 501 are slidably fitted with the second support beam 102 of the upper frame 1, and a locking device 5016 is arranged on the corresponding slider, which is used to fix the adjusting frame 501 after it is slid into place to prevent displacement during assembly; the locking device 5016 is quickly locked and unlocked by rotating the handle or pulling the lever, which is easy to operate and has high reliability; for example Figure 6 As shown, two sleeve mounting seats 502 are arranged in the U-shaped groove of the adjusting frame 501 along the Z-axis direction, any sleeve mounting seat 502 is connected with a mounting frame 5013 and a guide block 5015, the mounting frame 5013 is further connected with a second nut block 5014, the U-shaped groove of the adjusting frame 501 is provided with an adjusting screw 5011 threadedly connected with the second nut block 5014 and a guide rod 5012 slidably connected with the guide block 5015. In this embodiment, two adjusting screws 5011 are arranged on the adjusting frame 501 and are adapted to the two second nut blocks 5014, so that the height of each sleeve mounting seat 502 can be adjusted individually. In order to avoid interference between the upper and lower sleeve mounting seats 502, the servo motor 508 is installed at the end away from each other of the two sleeve mounting seats 502. In order to realize automatic operation, a controller is further arranged in the device, which is connected with the electric equipment in the application. For example, the controller and the servo motor 508 are connected by wired or wireless mode and support bidirectional signal interaction.

[0042] As shown in the figure, Figures 6-8 As shown, the sleeve mounting seat 502 is provided with a mounting groove, the first power shaft 503 and the second power shaft 504 are connected through the fixed support 505 and the adjusting support 506 in the mounting groove, the fixed support 505 is fixed in the mounting groove, the adjusting support 506 is slidably installed in the mounting groove, the adjusting support 506 is connected with a sliding block 5061 on one side, the sliding block 5061 is provided with a threaded groove, the inner wall of one side of the mounting groove is provided with a guide groove 5021 slidably connected with the sliding block 5061, and the guide groove 5021 is further connected with a manual screw rod 5022 connected with the threaded groove, as shown in the figure, Figure 10As shown, the end of the manual screw 5022 is provided with a hand wheel or wrench interface, which is convenient for the operator to rotate the manual screw 5022, and then drive the sliding block 5061 to displace along the guide groove 5021 through the threaded connection between the manual screw 5022 and the sliding block 5061, so as to change the position of the adjusting support 506 in the mounting groove to change the distance between the fixed support 505 and the adjusting support 506. The guide groove 5021 is designed in a T shape or a dovetail groove to ensure that the sliding block 5061 does not deviate laterally during movement, thereby improving positioning accuracy and stability. The telescopic assembly 507 includes a child transmission shaft 5075 and a mother transmission shaft 5076 connected in an axial sliding and circumferential fixed manner. The child transmission shaft 5075 is connected with one of the first power shaft 503 and the second power shaft 504, and the mother transmission shaft 5076 is connected with the other one of the first power shaft 503 and the second power shaft 504.

[0043] As shown in Figure 8 The child transmission shaft 5075 and the mother transmission shaft 5076 of the telescopic assembly 507 are connected in a circumferential fixed manner through a spline or keyway structure, allowing them to freely expand and contract in the axial direction to adapt to the dynamic displacement requirements during equipment assembly. Previously, the position of the adjusting support 506 in the mounting groove was changed by the manual screw 5022, thereby changing the distance between the fixed support 505 and the adjusting support 506. At this time, the relative position between the child transmission shaft 5075 connected with the fixed support 505 and the mother transmission shaft 5076 connected with the adjusting support 506 also changes. Since the child transmission shaft 5075 and the mother transmission shaft 5076 are connected by splines, the fixed support 505 and the adjusting support 506 can still transmit power to each other when the position changes. The child transmission shaft 5075 is directly connected with the first power shaft 503 through a coupling or flange, and the mother transmission shaft 5076 is connected with the second power shaft 504 in a similar manner. In addition, a scale is integrated on the opening of the mounting groove, which is convenient for determining the distance between the first power shaft 503 and the second power shaft 504 according to the distance between the two bolt holes on the hinge, so as to directly align the corresponding bolt holes after installing the sleeves and bolts on the two power shafts.

[0044] As shown in Figure 9As shown, the telescopic assembly 507 further comprises a first bevel gear 5071 and a second bevel gear 5072 installed in the fixed support 505, a first mandrel 5077, a third bevel gear 5073 and a fourth bevel gear 5074 installed in the adjusting support 506, and a second mandrel 5078, the first mandrel 5077 is rotatably installed in the fixed support 505 and one end of the first mandrel 5077 is fixedly connected with the child transmission shaft 5075, the first bevel gear 5071 and the second bevel gear 5072 are engaged, the first bevel gear 5071 is installed on the first mandrel 5077 and the second bevel gear 5072 is connected with one end of the first power shaft 503; the second mandrel 5078 is rotatably installed in the adjusting support 506 and one end of the second mandrel 5078 is fixedly connected with the mother transmission shaft 5076, the third bevel gear 5073 and the fourth bevel gear 5074 are engaged, the third bevel gear 5073 is installed on the second mandrel 5078 and the fourth bevel gear 5074 is connected with one end of the second power shaft 504; the first power shaft 503 and the second power shaft 504 on any sleeve mounting seat 502 are rotatable in the same direction. The telescopic assembly 507 transmits and changes the direction of the power of the first power shaft 503 and the second power shaft 504 rotatable in the same direction through two groups of bevel gear mechanisms; in the fixed support 505, the first power shaft 503 drives the second bevel gear 5072, which is engaged to make the first bevel gear 5071 rotate in the opposite direction, driving the first mandrel 5077 and the child transmission shaft 5075 to output; in the adjusting support 506, the second power shaft 504 drives the fourth bevel gear 5074, which is engaged to make the third bevel gear 5073 rotate in the opposite direction, driving the second mandrel 5078 and the mother transmission shaft 5076 to output. The child transmission shaft 5075 and the mother transmission shaft 5076 adopt a nested structure, and when the fixed support 505 and the adjusting support 506 are relatively telescoped, the power is continuously and stably transmitted through the rigid connection of the mandrel and the transmission shaft.

[0045] In the present embodiment, a camera 509 is installed on one side of the sleeve mounting seat 502 to simultaneously align two sleeves connected with the first power shaft 503 and the second power shaft 504, the camera 509 is preferably a CCD camera, and the characteristic photo of bolt installation abnormity is introduced into the control terminal, such as the inclination of the bolt or the misalignment of the bolt and the bolt hole; the camera 509 continuously takes photos of the bolts in the two sleeves, the control terminal compares the real-time photos with the characteristic photos, and judges whether the bolt installation abnormity phenomenon occurs.

[0051] Specifically, referring to Figure 13 As shown in the figure, the positioning assembly 703 includes a suction cup bracket 7031, a pneumatic suction cup 7032, a guide column 7033 and a guide sleeve 7034, two pneumatic suction cups 7032 are installed on the suction cup bracket 7031, the guide sleeve 7034 is installed on the support plate 701, one end of the guide column 7033 is fixedly connected with the suction cup bracket 7031, a limiting groove 70331 is formed in the guide column 7033 and the guide column 7033 is slidingly arranged in the guide sleeve 7034, the guide sleeve 7034 is provided with a locking nut 7035, and the limiting groove 70331 on the guide column 7033 passes through the bottom end of the locking nut 7035, so as to form circumferential limiting of the guide column 7033. By tightening the locking nut 7035, the guide column 7033 can be locked in the guide sleeve 7034.

[0052] Based on the scheme provided in embodiment two, the present embodiment two further provides an assembly method of the diesel generating set part automatic assembly equipment, including the following specific steps:

[0053] S1, placing the door plate 9 on the middle frame 2 and locking the door plate 9 through the limiting device 6;

[0054] S2, referring to Figure 1 As shown in the figure, the turnover device 4 grabs the door plate 9 in the horizontal state through the suction cup device 7, and then referring toFigure 12 As shown, the overturning device 4 is overturned to the vertical state to enter the waiting state; eight vacuum suction cups 702 are arranged on the support plate 701, corresponding to the installation of the left door plate 9 and the right door plate 9, for example, when the right door plate 9 is installed, the right door plate 9 needs to be limited to the right half of the support plate 701 through the limiting device 6, and then the six vacuum suction cups 702 located on the right side of the support plate 701 are used to grab the door plate 9.

[0055] S3, manually push the equipment close to the box body, and then push the overturning device 4 to send the door plate 9 into the door frame of the box body, and use hands to move the hinge to make it close to the outer wall of the box body, when the bolt hole on the hinge is aligned with the bolt hole on the outer wall of the equipment, use the positioning assembly 703 in the suction cup device 7 to fix the door plate 9 together with the support plate 701 as a whole on the outer wall of the equipment;

[0056] In step S3, when the bolt hole on the hinge of the door plate 9 is aligned with the bolt hole on the outer wall of the equipment, the pneumatic suction cup 7032 in the upper and lower positioning assemblies 703 sucks the outer wall of the equipment, and then the suction cup support 7031 together with the pneumatic suction cup 7032 is fixed through the locking nut 7035, so that the door plate 9 together with the support plate 701 is stably fixed on the outer wall of the equipment.

[0057] S4, adjust the height of the two sleeve mounting seats 502 according to the height of the hinge, and then separately adjust the distance between the first power shaft 503 and the second power shaft 504 in each sleeve mounting seat 502 to correspond to the bolt holes on the hinge, and then install the bolts in the sleeves and slowly move the tightening device 5 to insert the bolts in the sleeves into the corresponding bolt holes;

[0058] S4.1, during the adjustment process of the tightening device 5, the distance between the two sleeves needs to be adjusted according to the distance between the two bolt holes on the hinge, first adjust the distance between the first power shaft 503 and the second power shaft 504 by rotating the manual screw rod 5022, and install sleeves on the first power shaft 503 and the second power shaft 504, then adjust the height of each sleeve mounting seat 502 by adjusting the screw rod 5011, so that the upper sleeve mounting seat 502 is aligned with the upper bolt hole of the upper hinge, and the lower sleeve mounting seat 502 is aligned with the lower bolt hole of the lower hinge, to achieve the purpose of accurately adjusting the height of the two sleeve mounting seats 502; then, the camera 509 shoots the state of the bolts in the sleeves, and confirms that the bolts are not inclined and have no material shortage; if the detection is abnormal, step S5.2 is executed, and the insertion action is not needed, reducing the risk of mechanical interference.

[0059] In step S4.1, when adjusting the first power shaft 503 and the second power shaft 504 on any sleeve mounting seat 502, since the first power shaft 503 is fixed, the adjustment of the distance between the first power shaft 503 and the second power shaft 504 can be realized by adjusting the height of the second power shaft 504 through the corresponding manual screw rod 5022.

[0060] S5, start the servo motor 508 to tighten the bolt.

[0061] In order to ensure the stability and controllability of the bolt during the tightening process, in step S5, the controller controls the rotation number of the output shaft of the servo motor 508 to ensure the consistency of the bolt rotation torque, that is, the controller sends instructions to the servo motor 508 to ensure the consistency of the rotation number of the output shaft in forward rotation, reverse rotation or combination of forward and reverse rotation, and dynamically adjusts the instructions according to the running state (such as the current number of turns, rotation speed, etc.) feedback by the servo motor 508, to ensure the consistency of the actual rotation number and the target number of turns.

[0062] In the assembly process, two corresponding operation mechanisms are also given in this embodiment:

[0063] Mechanism one

[0064] S5.1, the controller controls the servo motor 508 to perform intermittent two-time tightening operation on the bolt.

[0065] S5.1.1, the first time is a pre-tightening operation, and the output shaft of the servo motor 508 is pre-rotated 1 to 2 turns.

[0066] S5.1.2, the second time is a formal tightening operation, and the output shaft of the servo motor 508 is further controlled to the target number of turns.

[0067] The purpose of mechanism one is to solve the problem that it is difficult to identify the deviation during the bolt installation process, and in the manual operation, the installation deviation may be forcibly tightened without being identified, thereby avoiding the consequences of subsequent bolts being difficult to disassemble due to forced tightening.

[0068] Mechanism two

[0069] S5.2, bolt installation abnormality detection. In step S5.1.1, the camera 509 collects real-time photos of the corresponding sleeve area, and the control terminal compares the real-time photos with the previously imported characteristic photos of bolt installation abnormalities to determine whether there is a bolt installation abnormality phenomenon, and changes the bolt installation action according to the abnormality phenomenon.

[0070] S5.2.1, when detecting that there is no bolt in the sleeve, the controller immediately sends a stop instruction to the servo motor 508, the upper frame 1 retreats along the X axis direction, and the tightening device 5 retreats to the initial waiting station of the upper frame 1. At the same time, the controller feeds back a lack of material signal, which is the coordinate position of the lack of material sleeve determined by image recognition of the camera 509, combined with the number of the sleeve mounting seat 502 to generate a unique position code, and then prompt the operator to supplement the bolts in the corresponding empty sleeve in time. When the tightening device 5 is reset, the controller can call the camera 509 again for confirmation, and then automatically continue to execute step S4.

[0071] The lack of material signal contains which power shaft of which sleeve mounting seat 502 is lacking, so as to add accurately.

[0072] S5.2.2, when detecting that only a single bolt in the sleeve is tilted, the controller first cuts off the electromagnetic clutch 5010 on the side of the normal bolt to make it separate, disconnects the servo motor 508 and the power shaft on that side, ensures that the bolt on that side remains stationary and does not participate in the subsequent correction action, thereby avoiding additional stress or torsion on the hinge; secondly, the servo motor 508 is controlled to rotate in reverse, since only the electromagnetic clutch 5010 on the abnormal bolt side remains combined, the power is transmitted to the sleeve driving the tilted bolt on that side, and the tilted bolt is slowly rotated out until it is completely separated from the bolt hole. During the bolt withdrawal process, the tightening device 5 will retreat a certain distance along the X axis to separate the sleeve from the bolt.

[0073] Then, the operator reinserts a new bolt into the sleeve and re-executes step S4 to continue the hinge installation process.

[0074] S5.2.3, when detecting that two bolts in the sleeve are tilted, the electromagnetic clutches 5010 of the two sleeves are kept engaged, and the servo motor 508 is simultaneously rotated in reverse at a lower speed and torque, the reverse torque of the servo motor 508 is limited to 50% of the forward torque, which can be real-time torque feedback through the encoder of the servo motor 508, and immediately stops when the threshold is exceeded, to avoid damaging the bolt or hinge; when the two sleeves drive the two tilted bolts to smoothly exit the bolt hole, the stress on the two hinges is simultaneously removed, avoiding new torsional deformation of the door panel 9 or hinge due to unilateral first exit. When the two bolts are removed, the door panel 9 is still fixed to the outer wall of the equipment by the positioning assembly 703. At this time, the hinge and the outer wall of the equipment may not be completely fitted, and need to be re-centered and calibrated by the operator. Then the operator needs to supplement new bolts or adjust the state of the bolts in the sleeve, so that the equipment needs to re-execute the positioning operation of step S4 and the tightening process of step S5.

[0075] In step S5.2.2, the purpose is to solve the immediate driving of the sleeve reverse rotation when the abnormality is found, but the reverse rotation of the two bolts at the same time can cause the deformation or skew of the hinge, that is, the simple simultaneous reverse rotation exit operation can cause the uncontrollable deviation of the relative pose of the bolt hole on the hinge and the bolt hole on the outer wall of the device, so the step S5.2.2 actually provides a reset mechanism to avoid the repeated positioning of the bolt hole, that is, since the normal bolt does not displace, the relative position of the hinge and the outer wall of the device is temporarily fixed by the bolt, avoiding the overall pose deviation, so that the bolt hole does not need to be repositioned.

[0076] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
