[0034] The following is a further detailed description of the specific implementation manners of the present utility model by describing the embodiments with reference to the accompanying drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0035] Specifically, as Figures 1 to 8 shown, a transfer device for an automobile general assembly production line includes a transfer rack 1, and self-locking universal wheels 2 are fixedly connected to the four corners of the bottom of the transfer rack 1. It further includes:

[0036] The Y-axis adjustment mechanism 3, two sets of the Y-axis adjustment mechanism 3 are provided and are respectively installed on both sides inside the transfer rack 1;

[0037] The X-axis adjustment mechanism 4, two sets of the X-axis adjustment mechanism 4 are also provided and are respectively installed between the two sets of Y-axis adjustment mechanisms 3;

[0038] The angle adjustment mechanism 5, four sets of the angle adjustment mechanism 5 are provided and are respectively installed on the two sets of X-axis adjustment mechanisms 4;

[0039] The door storage mechanism 6, four sets of the door storage mechanism 6 are also provided and are respectively correspondingly installed on the angle adjustment mechanisms 5;

[0040] The Y-axis tensioning mechanism 7, two sets of the Y-axis tensioning mechanism 7 are provided and are respectively correspondingly installed on the two sets of Y-axis adjustment mechanisms 3;

[0041] The X-axis tensioning mechanism 8, two sets of the X-axis tensioning mechanism 8 are also provided and are respectively correspondingly installed on the two sets of X-axis adjustment mechanisms 4.

[0042] It should be noted that during the transportation of the car door or the front hood, the distance between the four groups of car door storage mechanisms 6 needs to be adjusted according to the specific size of the car door. In this process, it is necessary to first drive the two groups of X-axis adjustment mechanisms 4 to move synchronously to one side by the Y-axis adjustment mechanism 3 to a suitable position, and then drive the four groups of car door storage mechanisms 6 to move to a suitable position synchronously by the X-axis adjustment mechanism 4. Then, adjust the distance between the two groups of X-axis adjustment mechanisms 4 by the Y-axis tensioning mechanism 7, that is, adjust the Y-axis distance between the symmetric two groups of car door storage mechanisms 6. Then, adjust the distance between every two car door storage mechanisms 6 arranged on the X-axis adjustment mechanism 4 respectively by the two groups of X-axis tensioning mechanisms 8. Finally, adjust the angle of each car door storage mechanism 6 by the angle adjustment mechanism 5 so that it can achieve the best adaptation to the car door or other components;

[0043] In addition, two of the four groups of car door storage mechanisms 6 are kept in the same straight line and parallel to the other two groups, so as to form a parallel plane for placing the car door or the front hood, etc. And due to the differences of each product, their shapes are also different. Therefore, it is necessary to adjust the two groups of car door storage mechanisms 6 in the same straight line respectively, even to form a trapezoidal state, etc. In this way, the appropriate size and angle can be flexibly adjusted according to the parts to be transferred, so as to increase the adaptability range of this device.

[0044] Furthermore, if the distance between the two groups of car door storage mechanisms 6 in the same straight line is too large and the car door requires a smaller size, at this time, only need to start the X-axis tensioning mechanism 8 to adjust its distance first, and then start the X-axis adjustment mechanism 4 to make it move to one side to meet the standard of the car door.

[0045] The Y-axis adjustment mechanism 3 includes a Y-axis slide rail 31 installed on the transfer rack 1, a Y-axis driving motor 32 installed at one end of the Y-axis slide rail 31, and two groups of Y-axis slide plates 33 slidably arranged on the Y-axis slide rail 31.

[0046] It should be noted that by starting the Y-axis driving motor 32 to drive the Y-axis slide rail 31 to work, the two groups of Y-axis slide plates 33 above it move synchronously and in the same direction, that is, drive the two groups of X-axis adjustment mechanisms 4 above the two groups of Y-axis slide plates 33 to move synchronously and in the same direction.

[0047] The X-axis adjustment mechanism 4 includes an X-axis slide rail 41 installed on the Y-axis slide plate 33, an X-axis driving motor 42 installed at one end of the X-axis slide rail 41, and two groups of X-axis slide plates 43 slidably arranged on the X-axis slide rail 41.

[0048] It should be noted that by starting the X-axis driving motor 42 to drive the X-axis slide rail 41 to work, the two groups of X-axis slide plates 43 above it move synchronously and in the same direction, that is, drive the angle adjustment mechanism 5 and the car door storage mechanism 6 above the four groups of X-axis slide plates 43 to move synchronously and in the same direction.

[0049] The angle adjustment mechanism 5 includes a base 51 slidably disposed on the X-axis slide plate 43, a servo motor 52 mounted on the base 51, and a turntable 53 connected to the output end of the servo motor 52.

[0050] It should be noted that by starting the servo motor 52 to drive the turntable 53 to rotate, the angle of each door storage mechanism 6 can be adjusted so that it can achieve the best fit with the door or other components.

[0051] The door storage mechanism 6 includes a claw seat 61 mounted on the turntable 53, a plurality of groups of claws 62 rotatably connected to the inside of the claw seat 61 through a pin shaft, a limit shaft 63 mounted above each group of claws 62, a positioning member 64 mounted at the front end of each group of claws 62, and a linkage member 65 mounted between every two groups of claws 62.

[0052] It should be noted that the door is moved above the door storage mechanism 6 by a robotic arm or a crane, so that its four corners respectively correspond to the four groups of door storage mechanisms 6, and then it descends. At this time, the lowermost limit shaft 63 is installed, that is, the last group of claws 62 is limited and will not rotate too much. Then the door descends. Since it lands on the claws 62, the upper claws 62 will be pressed down into the inside of the claw seat 61 until it lands on the lowermost claws 62 and is connected by the positioning member 64, that is, the storage of a group of doors is completed. If multiple doors need to be stored, only the above operation needs to be repeated.

[0053] The Y-axis tensioning mechanism 7 includes Y-axis fixing blocks 71 respectively mounted on two groups of Y-axis slide plates 33, a Y-axis double screw 72 rotatably connected between the two groups of Y-axis fixing blocks 71 and sequentially passing through the two groups of X-axis slide rails 41, and a Y-axis small motor 73 mounted on one side of the Y-axis fixing block 71;

[0054] The output shaft of the Y-axis small motor 73 is connected to the Y-axis double screw 72.

[0055] It should be noted that by starting the Y-axis small motor 73, the Y-axis double screw 72 rotates. The two groups of X-axis slide rails 41 are first slidably connected to the Y-axis slide plates 33 and are also threadedly connected to the Y-axis double screw 72. Therefore, the rotation of the Y-axis double screw 72 will drive the two groups of X-axis slide rails 41 to move synchronously in the opposite direction, that is, to adjust the distance between the two groups of parallel door storage mechanisms 6.

[0056] The X-axis tensioning mechanism 8 includes X-axis fixing blocks 81 respectively mounted on two groups of X-axis slide plates 43, an X-axis double screw 82 rotatably connected between the two groups of X-axis fixing blocks 81 and sequentially passing through the two groups of bases 51, and an X-axis small motor 83 mounted on one side of the X-axis fixing block 81;

[0057] The output shaft of the X-axis small motor 83 is connected to the X-axis double screw 82.

[0058] It should be noted that when the X-axis small motor 83 is started, the X-axis bidirectional screw 82 rotates. Since the base 51 is first slidably connected to the X-axis slide plate 43 and is also threadedly connected to the X-axis bidirectional screw 82, the rotation of the X-axis bidirectional screw 82 will drive the two groups of bases 51 to move synchronously in opposite directions, that is, to adjust the distance between the two groups of door storage mechanisms 6 on the same straight line.

[0059] There is a height difference between the two sides of the transfer rack 1, and a long stop rod 9 and a short stop rod 10 are respectively connected to the two sides of the transfer rack 1.

[0060] It should be noted that the height difference between the two sides of the transfer rack 1 facilitates the manipulator or lifting tool to drive the door to enter, and the long stop rod 9 and the short stop rod 10 protect the door on the left and right.

[0061] The following uses specific embodiments to elaborate on the specific working methods: Embodiment 1

[0062] During the transportation of the door or the front hood, it is necessary to adjust the distance between the four groups of door storage mechanisms 6 according to the specific size of the door. In this process, it is necessary to first drive the two groups of X-axis adjustment mechanisms 4 to move synchronously to one side by the Y-axis adjustment mechanism 3 to a suitable position, and then drive the four groups of door storage mechanisms 6 to move to a suitable position by the X-axis adjustment mechanism 4. Then, adjust the distance between the two groups of X-axis adjustment mechanisms 4 by the Y-axis tensioning mechanism 7, that is, adjust the Y-axis distance between the two symmetric groups of door storage mechanisms 6. Then, adjust the distance between every two door storage mechanisms 6 arranged on the X-axis adjustment mechanism 4 respectively by the two groups of X-axis tensioning mechanisms 8. Finally, adjust the angle of each door storage mechanism 6 by the angle adjustment mechanism 5 so that it can achieve the best adaptation to the door or other components. Embodiment 2

[0063] Two of the groups of door storage mechanisms 6 are kept on the same straight line and are parallel to the other two groups, so as to form a parallel plane for placing the door or the front hood, etc. Since each product is different, its shape is also different. Therefore, it is necessary to adjust the two groups of door storage mechanisms 6 on the same straight line respectively, so that they form a trapezoidal state, etc. In this way, the appropriate size and angle can be flexibly adjusted according to the parts to be transferred, thereby increasing the adaptability range of the device;

[0064] If the distance between the two groups of door storage mechanisms 6 on the same straight line is too large and the door requires a smaller size, at this time, only need to start the X-axis tensioning mechanism 8 to adjust its distance, and then start the X-axis adjustment mechanism 4 to move it to one side to meet the standard of the door.

[0065] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, all are within the protection scope of the present utility model.
