Advanced production technologies, such as numerical control machine tool processing, mold manufacturing, automated assembly lines, etc., are widely used to ensure the accuracy and consistency of parts. Automobile parts are processed step by step according to the technological process through an assembly line during production, and mechanical grippers are usually used to grab and transfer the parts on the assembly line.

[0003] For the current mechanical grippers used in production lines, a set of mechanical grippers work back and forth. This causes the mechanical grippers to need to transfer the parts after grabbing the parts on the assembly line and then return to continue grabbing, thereby reducing the efficiency of transferring the parts on the assembly line and not being conducive to improving production efficiency. Therefore, a special gripper for an automobile parts production line is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, for the current mechanical grippers used in production lines, a set of mechanical grippers work back and forth. This causes the mechanical grippers to need to transfer the parts after grabbing the parts on the assembly line and then return to continue grabbing, thereby reducing the efficiency of transferring the parts on the assembly line and not being conducive to improving production efficiency. The utility model proposes a special gripper for an automobile parts production line.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A special gripper for an automobile parts production line described in the utility model includes a mounting seat. The mounting seat is convex. Multiple groups of mounting holes are provided on both surfaces of the mounting seat. The protruding side of the mounting seat is located below. A protruding strip protrudes from the lower surface of one end of the mounting seat. An installation groove is provided on the lower surface of the protruding strip. An installation plate is slidably installed on the lower surface of the protruding strip through the installation groove. A rotating rod is rotatably installed on the lower surface of the installation plate. A cross bar is fixedly installed on the surface of the lower end of the rotating rod. The middle part of the upper surface of the cross bar is fixedly connected to the surface of the lower end of the rotating rod. Slide grooves are provided on the lower surfaces of both ends of the cross bar. One end of each of the two slide grooves penetrates to the outside. Extension rods are slidably installed in the two slide grooves. Manipulator bodies are installed on the lower surfaces of the opposite ends of the two extension rods.

[0006] Preferably, a slider is slidably installed in the installation groove. The lower surface of the slider is fixedly connected to the upper surface of the installation plate.

[0007] Preferably, a second cylinder is fixedly installed on the lower surface of the other end of the mounting base, and one end of the piston rod of the second cylinder slides through the mounting groove and is fixedly connected to one side surface of the slider.

[0008] Preferably, side plates are fixedly connected to both side surfaces of the mounting plate. The opposite side surfaces of the two groups of side plates are respectively slidably attached to both side surfaces of the protruding strips, and a motor is fixedly installed on one side of one group of side plates.

[0009] Preferably, a first gear is fixedly penetrated through the rotating rod, a second gear is fixedly installed on the output shaft of the motor, and the first gear is meshed with the second gear.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model can fixedly install the mounting base above the assembly line through the mounting holes on the mounting base. By driving the mounting plate to slide on the lower surface of the protruding strip, the cross bar can be driven to move horizontally in a straight line to adjust its working range. At the same time, the two groups of extension rods can be driven to slide towards both sides in the sliding grooves, driving the two groups of manipulator bodies to move towards both sides, and the grasping distance of the two groups of manipulator bodies can be adjusted. When grasping, first, one group of manipulator bodies grasps the parts on the assembly line, and then the rotating rod is driven to rotate to rotate the cross bar, swapping the positions of the two groups of manipulator bodies. Subsequently, the other group of manipulator bodies performs grasping, and the other group transports and releases the grasped parts. This process is repeated to improve production efficiency, thus solving the problem that after the mechanical gripper grasps the parts on the assembly line, it needs to transport the parts and then return to continue grasping, which reduces the efficiency of transporting the parts on the assembly line and is not conducive to improving production efficiency.

[0022] During operation, the mounting base 1 can be fixedly installed above the assembly line through the mounting holes 18 on the mounting base 1. By driving the mounting plate 14 to slide on the lower surface of the convex strip 2, the cross bar 6 will be driven to move horizontally in a straight line to adjust its working range. At the same time, two sets of extension rods 17 can be driven to slide on both sides in the sliding grooves 7, driving the two sets of manipulator bodies 10 to move to both sides, and the grasping distance of the two sets of manipulator bodies 10 can be adjusted. When grasping, first one set of manipulator bodies 10 grasps the parts on the assembly line, and then the rotating rod 15 is driven to rotate to rotate the cross bar 6, swapping the positions of the two sets of manipulator bodies 10. Subsequently, the other set of manipulator bodies 10 performs grasping, and the other set transports and releases the grasped parts. By working in this way repeatedly, the production efficiency is improved, thus solving the problem that after the mechanical gripper grasps the parts on the assembly line, the parts need to be transported and then returned to continue grasping, which reduces the efficiency of transporting the parts on the assembly line and is not conducive to improving the production efficiency.

[0023] Furthermore, a slider 13 is slidably installed in the installation groove 12, and the lower surface of the slider 13 is fixedly connected to the upper surface of the mounting plate 14.

[0024] During operation, the slider 13 is slidably installed in the installation groove 12, and due to the fixed connection between the slider 13 and the mounting plate 14, the mounting plate 14 is slidably installed on the lower surface of the convex strip 2.

[0025] Furthermore, a second cylinder 11 is fixedly installed on the lower surface of the other end of the mounting base 1, and one end of the piston rod of the second cylinder 11 slidably penetrates into the installation groove 12 and is fixedly connected to one side surface of the slider 13.

[0026] During operation, by starting the second cylinder 11 to work, the second cylinder 11 will expand and contract to push the slider 13 to slide in the installation groove 12, thereby achieving the purpose of electrically adjusting the cross bar 6.

[0027] Furthermore, side plates 16 are fixedly connected to both side surfaces of the mounting plate 14, and the opposite side surfaces of the two sets of side plates 16 are respectively slidably attached to both side surfaces of the convex strip 2, and a motor 5 is fixedly installed on one side of one set of side plates 16.

[0030] During operation, when the motor 5 operates, it drives the second gear 4 to rotate. When the second gear 4 rotates, it drives the first gear 3 to rotate. Due to the fixed connection between the first gear 3 and the rotating rod 15, the purpose of driving the rotating rod 15 to rotate by the motor 5 is achieved.

[0031] Furthermore, a first cylinder 9 is fixedly installed in the middle of the lower surface of the cross bar 6. The lower surfaces of the opposite ends of the two extension rods 17 are rotatably connected to a push rod 8, and the other ends of the two push rods 8 are rotatably connected to one end of the piston rod of the first cylinder 9.

[0032] During operation, by starting the first cylinder 9 to operate, when the first cylinder 9 contracts, it will pull the two push rods 8 to push the two extension rods 17 to slide and extend to both sides, so that the two extension rods 17 can be adjusted by the first cylinder 9.

[0033] Working principle: The mounting base 1 can be fixedly installed above the assembly line through the mounting holes 18 on the mounting base 1. By driving the mounting plate 14 to slide on the lower surface of the raised strip 2, it will drive the cross bar 6 to move horizontally in a straight line to adjust its working range. At the same time, the two extension rods 17 can be driven to slide to both sides in the chute 7, driving the two manipulator bodies 10 to move to both sides, and the grasping distance of the two manipulator bodies 10 can be adjusted. When grasping, first, one manipulator body 10 grasps the parts on the assembly line, and then the rotating rod 15 is driven to rotate to rotate the cross bar 6, swapping the positions of the two manipulator bodies 10. Then, the other manipulator body 10 performs grasping, and the other one transports and releases the grasped parts. This work is repeated to improve production efficiency.
