Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a fixing device for processing a thin plate includes a base 4, a pressing roller 6 and a hydraulic column 3 embedded at one end of the base 4, wherein both sides of the other end of the base 4 are fixedly installed with a pressing roller control device 7, a roller 5 is installed at the lower side of the pressing roller 6, a pressing block 1 is welded at the upper end of the hydraulic column 3, a semi-cylindrical convex block 2 is installed at one side of the upper surface of the base 4 close to the pressing block 1, the pressing roller control device 7 includes a shell 71, a worm wheel 73, a first worm 74 and a second worm 76, the lower end of the first worm 74 is fixedly connected with an output shaft of a first motor 78, the second worm 76 is fixedly connected with an output shaft of a second motor 77, and the first motor 78 and the second motor 77 are welded inside the shell 71.

In this embodiment, the press roll 6 is installed between two sets of press roll control devices 7, a rectangular chute 75 for supporting the shaft of the press roll 6 is formed in the press roll control devices 7, and the supporting shaft of the press roll 6 can rotate or slide in the rectangular chute 75.

Furthermore, the baffle plates 72 are welded at two ends of the supporting shaft of the press roller 6, the outer sides of the baffle plates 72 are welded with the worm gears 73 and rotate coaxially, and the baffle plates 72 limit the axial movement of the press roller 6 and protect the worm gears 73.

Further, the worm wheel 73 is interposed between the first worm 74 and the second worm 76, and is engaged by the teeth, and the rotation or movement of the worm wheel 73 is controlled by the rotation of the first worm 74 and the second worm 76.

Further, the first worm 74 has a right-hand helix and the second worm 76 has a left-hand helix. The first worm 74 and the second worm 76 rotate in the same direction, the worm wheel 73 rotates around a fixed point, the first worm 74 and the second worm 76 rotate in opposite directions, and the worm wheel 73 moves vertically.

Specifically, the rollers 5 are provided with two groups and are embedded in the base 4 through rotating connection, and the thin plate is clamped through the rollers 5, so that the working reliability is improved.

Specifically, the unfolding helix angle of the first worm 74 and the second worm 76 is smaller than the friction angle, so that a self-locking angle is formed, and the pressing roller 6 is ensured not to push the first worm 74 and the second worm 76 to rotate reversely due to the elastic force of the workpiece.

In this embodiment, the first motor 78 and the second motor 77 operate and rotate in opposite directions to move the press roller 6 upward or downward, the sheet is fed into the table of the base 4, the hydraulic column 3 at one end operates, the press block 1 presses down, the sheet is pressed by the matching bump 2, the first motor 78 and the second motor 77 rotate in opposite directions to continue rotating in opposite directions, the worm gear 73 presses down to fasten the sheet, and then the sheet rotates in the same direction to straighten the sheet.
