Detailed Description

As shown in fig. 1-3, a self-elevating rotatable polishing table comprises supporting rollers 1, wherein the supporting rollers 1 are arranged in pairs, each supporting roller 1 is arranged on a supporting plate 2, and the supporting plates 2 are Z-shaped. Every riding wheel 1 rotates through the drive of a first motor 3, can lift article 13 and drive article 13 rotatory in the later stage, conveniently polishes, welds. The upper end of the supporting plate 2 is connected with a sliding block, and the sliding block is in sliding fit with the sliding seat. A first screw rod 5 is rotatably arranged in the sliding seat along the length direction, the first screw rod 5 is in threaded connection with the sliding block, and the sliding block and the riding wheel 1 connected with the sliding block can be driven to move back and forth by the rotation of the first screw rod 5. The first screw rod 5 can adjust the interval between the two supporting plates 2 on the same side, so that the adjustable supporting plates are matched with objects with different diameters.

Two slides are installed on lift seat 4, and lift seat 4 lower extreme is equipped with folding fork arm 7, and folding fork arm 7 bottom is connected with removal seat 6, and rotatable the installing of second lead screw 8 on removing seat 6 in addition, the second lead screw 8 other end and lift seat 4 threaded connection through rotating two second lead screws 8, and the height of adjustable lift seat 4.

As shown in fig. 2, specifically, the folding fork 7 includes a first link 7.1 and a second link 7.2, and the first link 7.1 and the second link 7.2 are rotatably connected with each other through a pin in the middle. The upper ends of the first connecting rod 7.1 and the second connecting rod 7.2 are hinged with first sliding blocks, and the two first sliding blocks are arranged on a first sliding rail 7.3 at the lower end of the lifting seat 4 in a sliding manner. The lower ends of the first connecting rod 7.1 and the second connecting rod 7.2 are hinged with first travelling wheels, and the first travelling wheels move left and right along a first track 7.4 of the moving seat 6. When the upper and lower openings of the first connecting rod 7.1 and the second connecting rod 7.2 are gradually opened, the lifting seat 4 is gradually lowered, and when the upper and lower openings of the first connecting rod 7.1 and the second connecting rod 7.2 are gradually closed, the lifting seat 4 is gradually raised.

As shown in fig. 2, two second screw rods 8 on the same side are provided with a driving wheel 9, the corresponding moving seat 6 is provided with a driving wheel 10, two driving wheels 9 and the driving wheel 10 on the same side are wound with a driving belt 11, and the driving wheel 10 is driven to rotate by a second motor 12. When the second motor 12 is started, the two driving wheels 9 rotate in the same direction and at the same speed, so that the two second screw rods 8 also rotate in the same direction and at the same speed, and then the lifting seat 4 is adjusted to ascend or descend.

The working principle and the process are as follows: as shown in fig. 3, two sets of the lifting frames are moved to the left and right ends of the object 13, and then the first screw 5 is rotated to make the distance between the two riding wheels 1 on the same side large enough, so that the two riding wheels 1 on the same side can be gradually close to and positioned outside one end of the object 13. And then the first screw rod 5 is rotated reversely to ensure that the two riding wheels 1 are tightly attached to the side wall of one end of the object 13. Then the second motor 12 is started and drives the lifting seat 4 to rise, and the lifting seat 4 drives the objects 13 on the left and right riding wheels 1 to rise and leave the ground after rising. The two sets of holding frames are then pushed to move the object 13 to a welding station or a grinding station. The first motor 3 is started, the left and right first motors 3 drive the object 13 to synchronously rotate, and welding or polishing can be carried out.
