Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a car workpiece gripping device, including a mounting bracket 1 and a clamping mechanism 5. A plurality of groups of locking grooves 2 are penetrated and opened on one side of the top of the mounting bracket 1. A driving mechanism 3 for driving the clamping mechanism 5 to move in the X-axis direction is fixedly installed at the bottom of the mounting bracket 1. Two groups of adjusting mechanisms 4 for driving the clamping mechanism 5 to perform a gripping action are fixedly installed at the bottom of the driving mechanism 3. A sorting mechanism 6 for positioning the workpiece is fixedly installed between the two groups of adjusting mechanisms 4.

[0018] Among them, by setting the locking groove 2, the mounting bracket 1 can be fixedly connected to the external robotic arm by using a plurality of locking bolts. Subsequently, the driving mechanism 3 can drive the clamping mechanism 5 to move above the car workpiece. Subsequently, the adjusting mechanism 4 can adjust the position of the clamping mechanism 5. When the adjusting mechanism 4 drives the clamping mechanism 5 to descend, the sorting mechanism 6 can first contact the plate-shaped car workpiece to level the car workpiece. Subsequently, the adjusting mechanism 4 can drive a plurality of clamping mechanisms 5 to move, so that the gripping step of the car workpiece can be completed. Such a gripping device can ensure more accurate gripping and will not cause deviation in the gripping position.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3, the driving mechanism 3 includes a slide rail 7, a slider 8, a connecting block 9, a first mounting plate 10 and a driving cylinder 13. Two groups of slide rails 7 are fixedly installed at the bottom of the mounting frame 1. A slider 8 is slidably connected to the two groups of slide rails 7. The bottom of the slider 8 is fixedly connected to a first mounting plate 10 through a connecting block 9. A fixing plate 11 is fixedly installed at the top of the first mounting plate 10. A mounting seat 12 is fixedly installed on one side of the bottom of the mounting frame 1. A driving cylinder 13 is fixedly installed on one side of the mounting seat 12. The output end of the driving cylinder 13 is fixedly connected to the fixing plate 11. Two groups of support frames 27 are fixedly installed on both sides of the fixing plate 11 at the top of the first mounting plate 10. A support wheel 28 is rotatably connected to the support frame 27. The top of the support wheel 28 is in contact with the bottom of the mounting frame 1.

[0020] Among them, when it is necessary to grasp the automotive workpiece, the driving cylinder 13 pushes the fixing plate 11, so that the first mounting plate 10, the slider 8 and the sorting mechanism 4 and the clamping mechanism 5 connected to the first mounting plate 10 move towards the position of the automotive workpiece. During the moving process, the support frames 27 and the support wheels 28 provided can support the first mounting plate 10, so as to prevent the slider 8 and the slide rail 7 from shifting when the first mounting plate 10 drives the clamping mechanism 5 to move.

[0021] Please refer to Figure 1 , the adjustment mechanism 4 includes a second driving cylinder 14, a second mounting plate 15 and a double-acting cylinder 16. The bottom of the first mounting plate 10 is fixedly connected to a second driving cylinder 14. The output end of the second driving cylinder 14 is fixedly connected to a double-acting cylinder 16 through a second mounting plate 15. Both ends of the double-acting cylinder 16 are fixedly connected to a clamping mechanism 5.

[0022] Among them, after the clamping mechanism 5 moves above the automotive workpiece, the second driving cylinder 14 drives the double-acting cylinder 16 and the clamping mechanism 5 to move towards the automotive workpiece. Subsequently, the double-acting cylinder 16 can use multiple groups of clamping mechanisms 5 to move relative to each other, so as to complete the clamping and fixing of the plate-shaped automotive workpiece.

[0023] Please refer to Figure 1 and Figure 2 , the clamping mechanism 5 includes a second connecting plate 24, a clamping plate 25 and a clamping block 26. The bottom of the double-acting cylinder 16 is fixedly connected to a second connecting plate 24. One end of the second connecting plate 24 is fixedly connected to a clamping plate 25. Multiple groups of clamping blocks 26 made of rubber material are fixedly connected to one side of the clamping plate 25.

[0024] Among them, when the double-acting cylinder 16 works, it can drive the clamping plate 25 and the clamping block 26 to move towards both sides of the automotive workpiece, and then the force provided by the double-acting cylinder 16 can be used to perform the grasping step on the automotive workpiece.

[0025] Please refer to Figure 1 and Figure 2 The sorting mechanism 6 includes a first connecting plate 17, a telescopic rod 18, a pressing plate 19, a spring 21 and a support column 22. The first connecting plate 17 is fixedly installed on the second mounting plate 15. A plurality of groups of telescopic rods 18 are slidably connected to the first connecting plate 17. The bottom of the telescopic rod 18 is fixedly connected to the pressing plate 19. The top of the telescopic rod 18 is fixedly connected to a limiting plate 20. A spring 21 is fixedly connected to the bottom of the limiting plate 20 and on the outer surface of the telescopic rod 18. The bottom of the spring 21 is fixedly connected to the first connecting plate 17. A plurality of groups of support columns 22 are fixedly installed at the bottom of the pressing plate 19. A ball 23 is rotatably connected to the bottom of the support column 22.

[0026] Among them, when the second driving cylinder 14 drives the clamping mechanism 5 to descend, it can synchronously drive the sorting mechanism 6 to move downward and first contact the automotive workpiece. Subsequently, the ball 23 and the support column 22 will contact the automotive workpiece. When the second driving cylinder 14 continues to move, the telescopic rod 18 and the pressing plate 19 will move upward. The setting of the spring 21 can continuously provide pressure for the pressing plate 19, the support column 22 and the ball 23, so that the workpiece to be grasped can be in a horizontal state, which is convenient for the clamping mechanism 5 to clamp the automotive workpiece. When the clamping mechanism 5 clamps the automotive workpiece, if the automotive workpiece is not in the center position, the clamping mechanism 5 can be used to conveniently push the automotive workpiece to move along the ball 23 and clamp it in the center.

[0027] During use, first, by setting the locking groove 2, the multi-group locking bolt mounting brackets 1 can be fixedly connected to the external robotic arm. When it is necessary to grasp the automotive workpiece, the driving cylinder 13 pushes the fixed plate 11, causing the first mounting plate 10, the slider 8, and the sorting mechanism 4 and the clamping mechanism 5 connected to the first mounting plate 10 to move towards the position of the automotive workpiece. During the movement, the support frame 27 and the support wheels 28 provided can support the first mounting plate 10, thereby preventing the slider 8 and the slide rail 7 from shifting when the first mounting plate 10 drives the clamping mechanism 5 to move. After the clamping mechanism 5 moves above the automotive workpiece, the second driving cylinder 14 drives the double-axis cylinder 16 and the clamping mechanism 5 to move towards the automotive workpiece. Subsequently, the double-axis cylinder 16 can move multiple groups of clamping mechanisms 5 relative to each other, thereby completing the clamping and fixing of the plate-shaped automotive workpiece. When the double-axis cylinder 16 operates, it can drive the clamping plate 25 and the clamping block 26 to move towards both sides of the automotive workpiece, and then the force provided by the double-axis cylinder 16 can be used to perform the grasping step on the automotive workpiece. When the second driving cylinder 14 drives the clamping mechanism 5 to descend, it can synchronously drive the sorting mechanism 6 to descend and first contact the automotive workpiece. Subsequently, the balls 23 and the support columns 22 will contact the automotive workpiece. When the second driving cylinder 14 continues to move, the telescopic rod 18 and the pressing plate 19 will move upward, and the setting of the spring 21 can continuously provide pressure for the pressing plate 19, the support columns 22, and the balls 23, enabling the workpiece to be grasped to be in a horizontal state, facilitating the clamping mechanism 5 to clamp the automotive workpiece. When the clamping mechanism 5 clamps the automotive workpiece, if the automotive workpiece is not in the centered position, the clamping mechanism 5 can conveniently push the automotive workpiece to move along the balls 23 for centered clamping.
