[0017] Please refer to Figure 1-3The shown embodiment is an automated rapid positioning fixture for main roller production, comprising a fixed plate 1 and a clamping table 2. A driving motor is provided on one side of the clamping table 2, and the chuck is driven to rotate by the driving motor. The upper side of the fixed plate 1 contacts two storage seats 3, and the storage seats 3 are provided with V-shaped grooves 4. One side of the fixed plate 1 is fixedly connected to a support plate, and one side of the support plate is fixedly connected to a first motor. The output end of the first motor is fixedly connected to a first screw 5. The first motor can drive the first screw 5 to rotate and make the first slider 6 move laterally. The first screw 5 is threadedly connected to the first slider 6, and the first slider 6 is fixedly connected to the second motor. The output end of the second motor is fixedly connected to the second screw 7. The second motor controls the rotation of the second screw 7, which can cause the second slider 8 to move vertically, and then cooperates with the hydraulic rod 9 to realize the change in the height of the clamping table 2. The second screw 7 is threaded The second slider 8 is connected with a groove, and a hydraulic rod 9 is fixedly connected to the second slider 8. The upper end of the hydraulic rod 9 is fixedly connected to the clamping platform 2. A pad 10 is fixedly connected to one side of the storage seat 3. The upper end of the pad 10 is fixedly connected to the bracket 11 and the upper end of the bracket 11 is fixedly connected to the connecting plate 12. The upper end of the connecting plate 12 is fixedly connected to the third motor. The output end of the third motor is fixedly connected to the third screw 13. The third screw 13 and the fourth screw 17 are bidirectional screws. The third slider 14 is threadedly connected on both sides away from each other. The third motor can drive the third slider 14 to move relative to each other, and control the relative movement of two adjacent third sliders 14 and the distance sensor 15, thereby realizing cross-monitoring of the main roller shaft. The third slider 14 is fixedly connected to the distance sensor 15, and the monitoring directions of the four distance sensors 15 are cross-relative.

[0018] Among them, the storage seat 3 is fixedly connected to the protrusion, and the protrusion is threadedly connected to the two sides of the fourth screw 17 that are far away from each other. The fourth screw 17 is rotatably connected to the limiting groove 16. The limiting groove 16 is located on one side of the fixed plate 1. By manually adjusting the fourth screw 17, the two storage seats 3 can be driven to move relative to each other, thereby adapting to main rollers of different lengths and providing support for the main rollers.

[0019] Among them, the bottom end of the connecting plate 12 is fixedly connected to the electric push rod 18, the electric push rod 18 is plugged into the upper end of the sleeve 19, the sleeve 19 is fixedly connected to the upper side of the pressure plate 20, and the pressure plate 20 is located on the upper side of the storage seat 3. By setting the electric push rod 18 to extend and contract, the pressure plate 20 can be driven to press down, and can cooperate with the V-groove 4 of the storage seat 3 to limit the main roller shaft and realize rapid clamping.

[0020] Among them, the end of the electric push rod 18 is plugged with a positioning rod 21, and the positioning rod 21 is threadedly connected to the sleeve 19. By providing the positioning rod 21, different pressure plates 20 can be easily replaced.

[0021] Among them, the clamping plate 24 is fixedly connected to the upper end of the spring rod 23, the spring rod 23 is fixedly connected in the connecting groove 22, and the connecting groove 22 is located on the storage seat 3. By setting the spring rod 23 and cooperating with the clamping plate 24, the two end heads of the main roller shaft can be limited to improve stability.

[0022] Working principle: According to the size and length of the main roller, adjust the third screw 13 to drive the two storage seats 3 to move relative to each other, then place the main roller into the storage slot 4, and then start the electric push rod 18 to extend and drive the pressure plate 20 to press down, so that the main roller is stably limited in the V-groove. At this time, the third motor drives the third screw 13 to rotate, so that the four distance sensors 15 can achieve height movement and monitor the distance between them and the main roller. When the monitoring distances of the four distance sensors 15 are consistent, the sensor signal is sent to the first motor, the second motor and the hydraulic rod 9. At this time, the first screw 5 and the second screw 7 rotate, and the center point of the three-jaw chuck on the clamping table 2 corresponds to the center point of the main roller, and then rapid positioning and clamping are achieved, and the main rollers of different models can be limited, thereby improving the adaptability of clamping.
