[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal tensioning rod, it is inconvenient to quickly adjust the angle and position of the tensioning rod because the shapes and sizes of robots are different, which reduces work efficiency. Therefore, we propose a more convenient and practical tensioning device to meet the usage needs. Utility Model Content

[0004] The purpose of this invention is to provide a screw tightening device for industrial robot installation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw tightening device for industrial robot installation, including a mounting plate, an adjustment mechanism for adjusting the angle of the device on one side of the top of the mounting plate, the adjustment mechanism including a connecting plate, a first gear rotatably connected to the top center of the connecting plate, a second gear rotatably connected to one side of the top of the connecting plate, the teeth of the first gear and the second gear meshing, an adjustment component on one side of the connecting plate, and a tightening mechanism on one side of the adjustment mechanism for tightening screws.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Tightening equipment is required during robot assembly. This utility model provides a tightening equipment specifically for screw tightening during robot assembly. When using this equipment for tightening, it is necessary to select the appropriate tightening rod 606 according to the specifications and size of the screw to ensure the best tightening effect. Pay attention to the maintenance of the equipment, regularly check whether the various parts of the equipment are worn or damaged, and replace or repair them in time to ensure the normal operation of the equipment. If any abnormality is found during the use of the equipment (such as abnormal noise, overheating, etc.), use should be stopped immediately and the equipment should be inspected. Use can only continue after the fault has been eliminated.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a screw tightening device for industrial robot installation, including a mounting plate 1. An adjustment mechanism 5 is provided on one side of the top of the mounting plate 1 for adjusting the angle of the device. The adjustment mechanism 5 includes a connecting plate 501. A first gear 502 is rotatably connected to the top center of the connecting plate 501, and a second gear 503 is rotatably connected to one side of the top of the connecting plate 501. The teeth of the first gear 502 and the second gear 503 mesh with each other. An adjustment component is provided on one side of the connecting plate 501, and a tightening mechanism 6 is provided on one side of the adjustment mechanism 5 for tightening screws. A support frame 2 is fixedly connected to the top center of the mounting plate 1. A through hole is opened in the top center of the support frame 2, and a lead screw 3 is rotatably connected in the through hole. A lifting block 4 is slidably connected to the inner wall of one side of the support frame 2. The lifting block 4 and the lead screw 3 are threadedly connected. The connecting plate 501 and the lifting block 4 are connected to each other.

[0021] like Figure 2 As shown, the adjustment assembly includes a first rotating plate 504, which is connected to a second gear 503. A third gear 505 is rotatably connected to one side of the first rotating plate 504, and a fourth gear 506 is rotatably connected to the other side. The teeth of the third gear 505 and the fourth gear 506 mesh with each other. A second rotating plate 507 is fixedly connected to one side of the third gear 505. A fifth gear 508 is rotatably connected to one side of the second rotating plate 507, and a sixth gear 509 is rotatably connected to the other side of the fifth gear 508. The teeth of the fifth gear 508 and the sixth gear 509 mesh with each other. A third rotating plate 510 is fixedly connected to one side of the fifth gear 508.

[0022] It should be noted that during use, the device is first fixed to the assembly platform using the mounting plate 1. When the tightening angle needs to be adjusted, the motor drives the lead screw 3 to rotate and adjust the height of the lifting block 4. Then, the motor drives the first gear 502 to rotate and, through the second gear 503, drives the first rotating plate 504 to rotate and adjust the angle. Next, the motor drives the fourth gear 506 to rotate and, through the third gear 505, drives the second rotating plate 507 to rotate and adjust the angle a second time. Finally, the motor drives the sixth gear 509 to rotate and, through the fifth gear 508, drives the third rotating plate 510 to rotate and adjust the angle a third time. The adjustment mechanism 5 can simultaneously achieve vertical height adjustment and horizontal and tilt angle adjustment, which can quickly adapt to screw installation positions of different heights and angles, reduce the number of robot movements, and improve overall work efficiency.

[0023] like Figure 3 As shown, the tightening mechanism 6 includes a fixed plate 601, which is connected to the third rotating plate 510. The top of the fixed plate 601 has a slot, and a sliding frame 602 is slidably connected in the slot. A through hole is opened on one side of the top of the fixed plate 601, and a screw 603 is rotatably connected in the through hole. The screw 603 and the sliding frame 602 are threadedly connected. A rotating block 604 is rotatably connected to one side of the sliding frame 602. Multiple equidistant clamping rings 605 are fixedly connected to one side of the rotating block 604. A tightening rod 606 is provided on the inner wall of the clamping ring 605, and a rotating ring 607 is threadedly connected to the outer wall.

[0024] It should be noted that during use, the position camera is installed on the fixed plate 601 to adjust the angle of the tightening rod 606. At the same time, the rotating ring 607 is manually operated to make the clamping ring 605 clamp the tightening rod 606. After the angle is adjusted, the motor drives the screw 603 to rotate, which drives the sliding frame 602 to move along the fixed plate 601 and contact the screw. Then the motor drives the rotating block 604 to rotate, which drives the tightening rod 606 to rotate, tightening the screw. Conversely, it loosens the screw. The tightening mechanism 6 can adapt to tightening rods 606 of different diameters, which can not only ensure the clamping firmness, but also quickly replace tightening rods 606 of different specifications, meet the operation needs of various screw specifications, and improve the versatility of the equipment.

[0025] During use, the device is first fixed on the assembly platform using mounting plate 1. When the tightening angle needs to be adjusted, the motor drives the lead screw 3 to rotate, adjusting the height of the lifting block 4. Then, the motor drives the first gear 502 to rotate, which in turn drives the first rotating plate 504 to rotate via the second gear 503, adjusting the angle. Next, the motor drives the fourth gear 506 to rotate, which in turn drives the second rotating plate 507 to rotate via the third gear 505, adjusting the angle a second time. Finally, the motor drives the sixth gear 509 to rotate, which in turn drives the third rotating plate 510 to rotate via the fifth gear 508, adjusting the angle a third time. Once the angle is adjusted, the motor drives the screw 603 to rotate, causing the sliding frame 602 to move along the fixed plate 601 and contact the screw. Then, the motor drives the rotating block 604 to rotate, causing the tightening rod 606 to rotate, tightening the screw. Conversely, the screw is tightened or loosened. This device has a multi-degree-of-freedom angle adjustment capability, enabling precise adjustment of minute angles and meeting the high-precision angle requirements during screw installation.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
