Description

Technical Field

[0001] The utility model relates to a quick-install positioning device for a roller pressing main machine. Background Art

[0002] In the actual production of traditional cold roll forming units, if the production specifications need to be changed, the traditional way is to manually replace the mold roller after the equipment is shut down, and then start the machine after adjustment. Since manually replacing the roller mold of the entire line is labor-intensive, the re-adjustment time is long, time-consuming, labor-intensive and inefficient. In order to solve this problem, a variety of roller main machines of different specifications have appeared in the prior art. The roller main machine is a modular product and is fixed to the bottom machine base by bolts. When the production specifications need to be changed, multiple roller main machines of the same model can be directly replaced one by one. Multiple roller main machines together constitute a roller production line.

[0003] The method for replacing the roller main machine is: first remove the bolts between the roller main machine and the bottom machine base, then connect the roller main machine to the crane for lifting, move it to other areas, and then connect the roller main machine to be replaced to the crane, move it to the top of the bottom machine base, and slowly drop it to the bottom machine base. During the descent, multiple workers repeatedly adjust the position of the roller main machine to ensure that the front and back directions and the left and right directions are accurate. Due to the heavy weight of the roller main machine, its positioning is difficult, and multiple workers are required to assist in positioning in the front, back, left and right directions at the same time. Many workers are required and the positioning time is long. After the positioning is completed, the roller main machine needs to be fixed to the bottom machine base with bolts, which is inefficient.

When they are worn out after multiple replacements, they can be removed and replaced to avoid affecting the positioning accuracy of the roller pressing main machine 200.

[0038] The working principle of this embodiment is:

[0039] First, unlock the current roller pressing main machine 200. The specific operation is as follows: the telescopic end of the sliding drive cylinder 701 is extended, and the sliding positioning pull plate 702 slides to the right, and the top end is pressed against the block push-pull protrusion 704 on the right side. As the sliding drive cylinder 701 continues to extend, the roller pressing main machine 200 is pushed to move to the right. At this time, the left side of the roller pressing main machine 200 is released from the left anti-slip groove 602. At this time, the locking and anti-slipping of the roller pressing main machine 200 is released, and it is separated from the bottom machine base 100. Then, the lifting buckle on the crane is connected to the roller pressing main machine 200 through the lifting eye screw, and the roller pressing main machine 200 is lifted and moved to other areas.

[0040] Next, the next roller pressing main machine 200 to be replaced is connected to the crane, moved to the top of the bottom machine base 100, and slowly lowered downward. Only one worker is required to operate during the lowering process. The worker first adjusts the roller pressing main machine 200 in the front and rear directions so that the roller pressing main machine 200 slides down along the front guide inclined surface 302 or the rear guide inclined surface 402. At this time, the roller pressing main machine 200 can quickly enter between the front positioning block 301 and the rear positioning block 401. In this process, the V-shaped groove 803 and the V-shaped protrusion 804 also play an auxiliary positioning role; at the same time, the worker also adjusts the left and right directions so that the roller pressing main machine 200 slides down along the right guide inclined surface 502, and the roller pressing main machine 200 falls into After reaching the bottom machine base 100, the sliding positioning pull plate 702 is located between the left and right block push-pull protrusions 704, and then the telescopic end of the sliding drive cylinder 701 retracts and contacts with the left block push-pull protrusion 704, pulling the roller pressing main machine 200 to move to the left as a whole until the left end of the roller pressing main machine 200 abuts against the left positioning block 601. At this time, the pull plate anti-slip protrusion 705 is engaged with the block anti-slip groove 706, and the bottom end of the roller pressing main machine 200 extends into the left anti-slip groove 602 for engagement, and the sliding drive cylinder 701 is locked and fixed in this position, and positioning and fixing are completed in the front and back, left and right, and up and down. Finally, the connection between the crane and the roller pressing main machine 200 is released. Multiple roller pressing main machines 200 are replaced one by one in this way. Since the position of each roller pressing main machine 200 is accurate, the positions between the multiple roller pressing main machines 200 are accurate. After all are replaced, a complete roller pressing production line can be formed, which can be used after connecting the power, shortening the equipment debugging time.

[0041] The utility model adopts the front and rear positioning devices and the left and right positioning devices in conjunction with the crane, which can quickly realize the front and rear and left and right positioning of the roller pressing main machine 200. At the same time, the sliding anti-slip device 700 is used to realize the locking and anti-slipping of the roller pressing main machine 200 in the up and down directions, replacing the traditional screw fixing method to achieve screw-free quick installation. It is simple to replace, easy to operate, reduces the number of workers, and has a high replacement efficiency.
