[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0023] Example: Figure 1-4 As shown, the utility model is an ultra-thin workpiece clamping device for automatically tightening nuts, comprising a mounting plate 1 and a base 101, a linear module 2 is fixedly connected to the lower end of the mounting plate 1, a mounting bracket 3 is fixedly installed on the slide of the linear module 2, a linear module 2 4 is fixedly installed on one side of the mounting bracket 3, a slider of the linear module 2 4 is fixedly connected to an L-shaped frame 5, an electric screwdriver 6 is fixedly installed inside the L-shaped frame 5, a telescopic rod 7 is fixedly connected to one side of the L-shaped frame 5, and a pressing pin 8 is fixedly connected to the output end of the telescopic rod 7.
[0024] Among them, a gear box 9 is fixedly installed on the inner side of the L-shaped frame 5, and the output end of the electric screwdriver 6 passes through the gear box 9 and is fixedly connected to a gear 10. By setting the electric screwdriver 6, manual work is replaced by electricity, so that the production efficiency is improved.
[0025] Among them, the inner lower end of the gear box 9 is rotatably connected to the gear 2 11 through a rotating shaft, and the gear 2 11 is meshed and linked with the gear 1 10. One side of the gear 2 11 is meshed and connected with the gear 3 12. By setting the gear 13, the nut in the gear 13 can be tightened when the electric screwdriver 6 rotates, thereby reducing the generation of labor.
[0026] Among them, the top of the mounting plate 1 is fixedly connected to a fixing plate 13, the top of the fixing plate 13 is fixedly installed with a 3D camera 14, and the bottom of the fixing plate 13 is fixedly connected to a camera mounting plate 15. By setting the 3D camera 14, the 3D camera 14 can accurately locate the bolt position of the loading position by taking pictures.
[0027] Among them, a hydraulic cylinder 16 is fixedly welded to one side of the L-shaped frame 5, and a baffle 17 is fixedly connected to the output end of the hydraulic cylinder 16. By setting the baffle 17, the gasket can be placed automatically without manual placement, which further improves the production efficiency.
[0028] Among them, a leakage hole 18 is opened at the bottom of the gear box 9, a nut 19 is arranged inside the gear three 12, and the nut 19 can pass through the leakage hole 18. A gasket 20 is arranged at the lower end of the nut 19. By setting the leakage hole 18, it can be more accurately connected with the bolt and automatically screwed in, so that the accuracy is higher.
[0029] Among them, the top of the base 101 is fixedly connected with a bolt 21, and a limit block 22 is set at the lower part of the lower pressure pin 8, and the limit block 22 movably passes through the bolt 21. By setting the limit block 22, the limit block 22 can be accurately passed through the bolt 21, so that the nut can be automatically tightened in a shorter time, which is convenient to use.
[0030] Working principle: When in use, first the 3D camera 14 starts taking pictures to accurately determine the position of the bolt 21 of the loading base 101. According to the precise position given by the 3D camera 14, the bottom slide of the linear module 2 drives the gear box 9 to adjust its position to the position of the bolt 21, driving the workpiece inside the mounting bracket 3 to move inward as a whole, and use the upper front end of the gear box 9 to support the limit block 22. At the same time, the telescopic rod 7 drives the pressing pin 8 to press down, and the limit block 22 is accurately inserted into the bolt 21 of the loading base 101. After it is placed in place, the hydraulic cylinder 16 drives the lower baffle 17. After the telescopic rod 7 drives the pressing pin 8 to rise, the linear module 2 4 drives the workpiece in front of the L-shaped frame 5 to descend, and the electric screwdriver 6 starts to rotate, and the nut 19 is driven into the corresponding bolt 21. When the sensor of the linear module 2 4 shows that it has dropped into place, the electric screwdriver 6 continues to rotate until the electric screwdriver 6 measures that the torque reaches the specified level and stops. The linear module 2 4 rises, driving the workpiece in front of the L-shaped frame 5 to rise. When the sensor of the linear module 2 4 shows that it has risen to the right position, the bottom slide of the linear module 1 2 drives the workpiece inside the mounting bracket 3 to move outward as a whole to the maximum displacement, thereby completing this cycle and entering the next cycle.
