Description

Technical Field

[0001] This utility model relates to the field of roller conveyor inspection technology, and more specifically, it relates to an adaptive clamping and positioning device for roller conveyors. Background Technology

[0002] Roller conveyors are transport equipment that uses the rotation of cylindrical rollers to transport rolled products. They connect the various processes in the rolling production process, realize mechanized operation, greatly improve working conditions, increase production efficiency, and provide conditions for automated operation. Roller conveyors mainly consist of guide plates, guard plates, several rollers, multiple motors and their drive shafts and reducers. The rollers play a very important role in the process. During use, roller conveyors need to be inspected regularly to check for surface damage. When inspecting the rollers, a clamping and positioning structure is needed to clamp and position the rollers.

[0003] A search revealed that Chinese utility model patent CN202122861207.6 discloses a detection device for a roller conveyor, including a fixed base, a movable platform movably connected to the top of the fixed base, fixed plates fixedly connected to the front and rear sides of the top of the movable platform, a motor threadedly connected to the front end of the top of the movable platform and located on the front of the fixed plate by bolts, a drive wheel fixedly connected to the output shaft of the motor, and movable columns movably connected to the upper ends of the two fixed plates on opposite sides by bearings.

[0004] In use, first, the threaded column is turned to disengage the bottom of the threaded column from the lower clamping block. Then, the threaded column is pulled upward, causing the upper clamping block to move upward and separate from the lower clamping block. At the same time, the upper clamping block causes the limiting plate to rotate with the help of the rotating shaft, thereby fixing the position of the upper clamping block. Then, the two ends of the roller are placed on the surfaces of the two lower clamping pads respectively. Then, the above operation is reversed to clamp and fix the roller. The space between the upper and lower clamping blocks is fixed, and the gap between them is not easy to adjust. It is not suitable for clamping and positioning rollers of different diameters. In addition, it is not easy to adjust the distance between the two fixed plates, and it is not suitable for clamping and positioning rollers of different lengths. Utility Model Content

[0030] Please see Figures 1-5An adaptive clamping and positioning device for a roller conveyor includes a fixed base 1. Four support legs 25 are fixedly connected to the bottom end of the fixed base 1 to facilitate supporting the fixed base 1 to a certain height. Two fixed plates 2 are slidably disposed at the top end of the fixed base 1. An adjustment mechanism for adjusting the distance between the two fixed plates 2 is provided at the top end of the fixed base 1. A rotating tube 3 is rotatably connected to each of the two fixed plates 2. Four sliding plates 4 are evenly slidably disposed on each of the two rotating tubes 3. Clamping seats 5 are fixedly connected to one end of each of the four sliding plates 4 extending into the rotating tube 3. Rubber pads are fixedly connected to each of the clamping seats 5. 21. The rollers are protected. The sides of the four slide plates 4 are fixedly connected to the fixed posts 6. The outside of the rotating tube 3 is rotatably connected to the rotating ring 7. The rotating ring 7 is provided with four arc-shaped grooves 8. The four fixed posts 6 are respectively inserted into the four arc-shaped grooves 8. The outside of the rotating ring 7 is fixedly connected to the first connecting seat 9. The first electric cylinder 10 is rotatably connected to the first connecting seat 9. The other end of the first electric cylinder 10 is rotatably connected to the second connecting seat 11. The bottom end of the second connecting seat 11 is fixedly connected to the side end of the rotating tube 3. The fixed plate 2 is connected to the rotating mechanism that drives the rotating tube 3 to rotate.

[0031] Specifically, the first electric cylinder 10 drives the rotating ring 7 to rotate. During the rotation of the rotating ring 7, the four fixed columns 6 slide inside the four arc-shaped grooves 8 respectively. The four fixed columns 6 drive the corresponding slide plates 4 and clamping seats 5 to move respectively, thereby adjusting the position of the four clamping seats 5 at the same time. This makes it easy to adjust the gap between the four clamping seats 5 according to the diameter of the roller on the roller conveyor, which is suitable for clamping and positioning rollers of different diameters.

[0032] Please see Figure 1 The adjustment mechanism includes a first motor 12, an adjustment groove 13 at the top of the fixed base 1, a bidirectional screw 14 rotatably connected inside the adjustment groove 13, two adjustment seats 15 symmetrically threaded to the outside of the bidirectional screw 14, the tops of the two adjustment seats 15 being fixedly connected to the bottoms of the two fixed plates 2 respectively, the first motor 12 being mounted on the side of the fixed base 1, the output end of the first motor 12 being fixedly connected to the side of the bidirectional screw 14, and two first fixing rods 16 being fixedly connected inside the adjustment groove 13, both of the first fixing rods 16 slidingly engaging with the two adjustment grooves 13 to ensure that the adjustment seats 15 slide stably inside the adjustment groove 13.

[0033] Specifically, the first motor 12 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 causes the two adjusting seats 15 to move in opposite directions inside the adjusting groove 13. The two adjusting seats 15 respectively drive the two fixed plates 2 to move, thereby adjusting the distance between the two fixed plates 2. This facilitates adjusting the distance between the two fixed plates 2 according to the distance between the roller conveyors, and is suitable for clamping and positioning rollers of different lengths.

[0034] Please see Figure 2 and Figure 4 The rotating mechanism includes a second motor 17, a first motor 12 mounted on the top of the fixed plate 2, a gear 18 fixedly connected to the output end of the first motor 12, a gear ring 19 fixedly connected to the outside of the rotating tube 3, the gear ring 19 meshing with the gear 18, and two second fixed rods 20 fixedly connected to one rotating tube 3, the two second fixed rods 20 slidingly engaging with another rotating tube 3, driving the other rotating tube 3 to rotate during the rotation of one rotating tube 3.

[0035] Specifically, the second motor 17 drives the gear 18 to rotate, the gear 18 drives the gear ring 19 to rotate, the gear ring 19 drives the rotating tube 3 to rotate, and the rotating tube 3 drives another rotating tube 3 to rotate through two second fixed rods 20.

[0038] In summary, when using the overall equipment:

[0039] The rollers on the roller conveyor are hoisted to the middle of the two rotating tubes 3 by a hoisting device. Then, the first motor 12 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 causes the two adjusting seats 15 to move in opposite directions inside the adjusting groove 13. The two adjusting seats 15 drive the two fixed plates 2 to move, adjusting the distance between the two fixed plates 2 so that the two ends of the rollers are inserted into the interior of the two rotating tubes 3. Then, the first electric cylinder 10 drives the rotating ring 7 to rotate. During the rotation of the rotating ring 7, the four fixed columns 6 slide inside the four arc-shaped grooves 8, and the four fixed columns 6 drive the corresponding sliding plates. 4 and clamping seats 5 move, so that the four clamping seats 5 clamp and fix the roller. Then, the second motor 17 drives the gear 18 to rotate, the gear 18 drives the gear ring 19 to rotate, the gear ring 19 drives the rotating tube 3 to rotate. The rotating tube 3 drives another rotating tube 3 to rotate through two second fixed rods 20. The rotation of the two rotating tubes 3 drives the clamping and positioning roller to rotate, so that the side of the roller to be inspected faces the people. Then, the second electric cylinder 23 drives the positioning seat 24 to move, so that the side end of the positioning seat 24 abuts against the side end of the rotating tube 3, fixing the rotating tube 3 and the roller fixed inside the rotating tube 3, thereby clamping and positioning the roller.
