[0002] In automotive manufacturing, shaft assembly assist devices are commonly used to install components such as shafts and bearings to ensure they are correctly installed in the correct position and orientation. Existing fully automated shaft assembly devices (Announcement No.: CN112872755B) have the following shortcomings during use:

[0003] During use, the workpiece is clamped by the first push block and the second push block in the assembly jig. After the assembly is completed, the assembled component needs to be taken out from the assembly jig by a robot and placed on a conveyor belt. However, before taking it out, the first push block and the second push block need to move to no longer clamp the workpiece, and then the workpiece can be taken out. This is rather troublesome and time-consuming. For this reason, this patent proposes an automobile shaft assembly robot that is easy to position to solve the above problem. Utility Model Content

[0012] The difference between this automobile shaft assembly robot that is easy to position and the existing technology is that the telescopic rod drives the connecting plate and the first robot to move downward, and the connecting plate moves downward so that the insertion rod moves downward and is inserted into the insertion hole, and the first spring squeezes the extrusion plate, and the extrusion plate is squeezed, thereby driving the sliding frame to move downward, and the sliding frame moves downward so that the third spring is no longer squeezed, so that the third spring drives the connecting rod to move outward, and the mobile clamp moves outward, thereby no longer clamping the rotating shaft, so that the first robot can clamp the rotating shaft and take it out. During the removal process, the telescopic rod drives the fixed plate to move upward, but the extrusion plate still has a certain amount of extrusion on the mounting plate. When the rotating shaft is completely taken out, the extrusion plate leaves the mounting plate, so that the mobile clamp no longer clamps the rotating shaft during the material removal process, which does not require additional operation and saves a lot of time.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The shaft assembly auxiliary device is usually used in automobile manufacturing to install parts such as shafts or bearings to ensure that they are correctly installed in the correct position and direction. The automobile shaft assembly robot provided by the utility model moves downward through the robot, thereby driving the mobile clamp 21 to move outward, so that the first robot can clamp the shaft. After clamping, the first robot moves upward. After moving to a certain distance, the mobile clamp 21 returns to its original position. Then the first robot clamps the next group of shafts and then moves downward. In this way, the mobile clamp 21 moves outward to place the shaft between the mobile clamp 21 and the fixed clamp 20. The first robot moves the mobile clamp 21 upward to return to its original position to clamp the shaft. In this way, during the material picking process, there is no need to wait for the mobile clamp 21 to move before it can pick up the material, which saves a certain amount of time.

[0020] like Figures 1-4As shown, the utility model provides a technical solution: an automobile shaft assembly manipulator that is easy to position, comprising a workbench 1, a turntable 2 is rotatably connected to the top of the workbench 1, a connecting frame 7 is fixed to the top of the turntable 2, a mounting shell 19 is fixed to the top of the connecting frame 7, a fixing fixture 20 is fixed to the top of the mounting shell 19, a limit plate 25 is fixed to the inner wall of the mounting shell 19, a moving rod 24 is slidably connected to one side of the limit plate 25, a connecting rod 18 is fixed to one end of the moving rod 24, and the connecting rod 18 is slidably connected to the inner wall of the mounting shell 19. It is dynamically connected to one side of the mounting shell 19, a third spring 23 is fixed between the connecting rod 18 and the limit plate 25, a mobile clamp 21 is fixed to the top of the connecting rod 18, a fixed frame 22 is fixed to one side of the connecting frame 7, and a sliding frame 14 is slidably connected to one side of the fixed frame 22. The connecting rod 18 contacts one side of the sliding frame 14, and a sliding column 16 is fixed to the bottom end of the sliding frame 14. The sliding column 16 is inserted into the turntable 2, and a second spring 15 is fixed between the bottom end of the sliding frame 14 and the inner wall of the bottom end of the fixed frame 22. A support frame 3 is fixed to the top of the workbench 1, and the top of the support frame 3 is rotatably connected to the rotating rod 4. A telescopic rod 5 is fixed to the bottom end of the rotating rod 4, and a connecting plate 6 is fixed to the telescopic end of the telescopic rod 5. A first manipulator is installed at the bottom end of the connecting plate 6. A fixed plate 8 is fixed to one side of the connecting plate 6, and an insertion rod 9 is fixed to the bottom end of the fixed plate 8. The outer wall of the insertion rod 9 is slidably connected to an extrusion plate 11, and a first spring 10 is fixed between the top of the extrusion plate 11 and the bottom end of the fixed plate 8. A mounting plate 12 is fixed to the top of the sliding frame 14, and a socket 13 is provided at the top of the mounting plate 12, and the insertion rod 9 is adapted to the socket 13.

[0021] It should be noted that by setting the fixed clamp 20 and the movable clamp 21, the rotating shaft can be clamped, thereby facilitating the positioning of the rotating shaft by the manipulator, and the connecting plate 6 and the first manipulator are driven downward by the telescopic rod 5. The connecting plate 6 moves downward so that the insertion rod 9 moves downward and is inserted into the insertion hole 13. The first spring 10 squeezes the extrusion plate 11, and the extrusion plate 11 is squeezed, thereby driving the sliding frame 14 to move downward. The sliding frame 14 moves downward so that the third spring 23 is no longer squeezed, so that the third spring 23 drives the connecting rod 18 to move outward, and the movable clamp 21 moves outward, thereby no longer clamping the rotating shaft, so that the first manipulator can clamp the rotating shaft and take it out. During the removal process, the telescopic rod 5 drives the fixed plate 8 to move upward, but the extrusion plate 11 still has a certain squeeze on the mounting plate 12. When the rotating shaft is completely taken out, the extrusion plate 11 leaves the mounting plate 12, the sliding frame 14 moves upward, and the connecting rod 18 moves inward to squeeze the third spring 23.

[0022] like Figure 2 、 Figure 3 and Figure 4As shown, a connecting groove is provided at the top of the turntable 2, a limiting groove is provided at the bottom of the connecting groove, a sliding block 17 is fixed to the bottom end of the sliding column 16, the sliding column 16 is slidably connected in the connecting groove, and the sliding block 17 is slidably connected in the limiting groove. A first motor is fixed to the bottom end of the workbench 1, and the output end of the first motor passes through the workbench 1 and is fixed to the bottom end of the turntable 2. A second motor is fixed to the inner wall of the support frame 3, and the output end of the second motor passes through the support frame 3 and is fixed to the rotating rod 4. A controller is installed at the top of the workbench 1, and the controller is electrically connected to the telescopic rod 5, the first motor and the second motor. In addition, a plurality of other manipulators are provided at the top of the workbench 1 to assemble the rotating shaft respectively, which can speed up the assembly efficiency of the rotating shaft.

[0023] It should be noted that the turntable 2 is driven to rotate by the first motor, and the rotation of the turntable 2 drives the rotation shaft to rotate, so that assembly can be performed under different manipulators. In addition, the rotating rod 4 is driven to rotate by the second motor, so that the first manipulator can place the rotation shaft next to the workbench 1 after taking it out.

[0024] Working principle: The telescopic rod 5 is started by the controller, and the telescopic rod 5 drives the connecting plate 6 and the first manipulator to move downward. The connecting plate 6 moves downward so that the insertion rod 9 moves downward and is inserted into the socket 13. The first spring 10 squeezes the extrusion plate 11. The extrusion plate 11 is squeezed, thereby driving the sliding frame 14 to move downward. The sliding frame 14 moves downward so that the third spring 23 is no longer squeezed. In this way, the third spring 23 drives the connecting rod 18 to move outward, and the mobile clamp 21 moves outward, thereby no longer clamping the rotating shaft. In this way, the first manipulator can clamp the rotating shaft and take it out. During the removal process, the telescopic rod 5 drives the fixed plate 8 to move upward, but the extrusion plate 11 still has a certain squeeze on the mounting plate 12. When the rotating shaft is completely taken out, the extrusion plate 11 leaves the mounting plate 12, the sliding frame 14 moves upward, and the connecting rod 18 moves inward to squeeze the third spring 23.

[0025] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
