[0019] like Figures 1-4 As shown, a positioning and marking device for the lower input shaft of a steering column includes a table 1, a base 2, a clamping mechanism, a touch sensor 3, and a laser marking device 4; the table 1 is provided with the base 2 and the laser marking device 4, the base 2 is provided with the clamping mechanism, and the clamping mechanism is provided with the touch sensor 3.

[0020] The clamping mechanism includes a cylinder 5, a push rod 6, a lower clamping block 7, an upper clamping plate 8, a support column 9, and a guide column 10. The cylinder 5 and support column 9 are mounted on the base 2. The top of the support column 9 is connected to the lower clamping block 7. The output end of the cylinder 5 is equipped with a push rod 6, which passes through the lower clamping block 7 and connects to the upper clamping plate 8. The top surface of the lower clamping block 7 has a three-step structure. The first step has a positioning groove 11, in which the lower input shaft 13 is placed. The second step has the push rod 6, on which a spring 12 is fitted to assist the upper clamping plate 8 in resetting. The third step has the guide column 10, which provides tactile feedback. The touch sensor 3 is located on the outer side of the third stage, facing the bottom surface of the upper clamping plate 8. The guide post 10 is connected to the upper clamping plate 8. The upper clamping plate 8 has a positioning groove 11 at the corresponding position, and a clamping station is formed between the two positioning grooves 11. The clamping station is located vertically below the marking end of the laser marking device 4. The positioning groove 11 is a contour groove, and the contour groove structure is matched with the spline structure at both ends of the lower input shaft 13. The distance from the touch sensor 3 to the bottom surface of the upper clamping plate 8 is equal to the distance from the marking position of the lower input shaft to the upper surface of the upper clamping plate 8. The touch sensor 3 is communicatively connected to the laser marking device 4.

[0021] When in use, the lower input shaft 13 is placed in the third-order positioning groove 11, and the angle of the marking position of the lower input shaft 13 is positioned through the cooperation of the profiling groove and the spline, the air cylinder 5 is started, the upper clamping plate 8 is driven to descend, in the process of descending of the upper clamping plate 8, the upper end of the lower input shaft 13 is gradually inserted into the positioning groove 11 of the upper clamping plate 8, when the bottom surface of the upper clamping plate 8 contacts the touch sensor 3, the marking position of the lower input shaft 13 is lifted to be flush with the upper surface of the upper clamping plate 8. At this time, the air cylinder 5 stops, and the laser marker 4 performs laser marking on the marking position of the lower input shaft 13. When the lower input shaft 13 is completed marking, the air cylinder 5 and the spring 12 drive the upper clamping plate 8 to reset, the lower input shaft 13 completed marking is taken out from the clamping station, and the next lower input shaft 13 to be marked is placed. Through the cooperation of the clamping and positioning of the lower input shaft and the marking and writing, the laser marker performs laser marking on the marking position of the lower input shaft when the clamping and positioning of the lower input shaft is completed, which not only speeds up the production efficiency, but also ensures the accuracy of the marking position of the lower input shaft, prevents the missing writing, improves the product qualification rate, and reduces the labor intensity.
