Description

Technical Field

[0001] The present application relates to the technical field of plate positioning, and in particular to a plate positioning device for a laser plate cutting machine. Background Art

[0002] Laser cutting machine, also known as laser cutting machine, focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] However, in actual applications, most of the existing laser cutting machines usually require manual position correction of the plate when in use to ensure that the plate and the laser cutting head are in the same horizontal position to complete the positioning work. However, due to the large deviation in manual correction during the correction process, multiple corrections are often required. This is why a lot of time is wasted, resulting in reduced work efficiency. At the same time, some plates are of large mass, and the manual correction process will accelerate worker fatigue, which will in turn lead to a decrease in correction accuracy.

[0004] Therefore, those skilled in the art provide a plate positioning device for a laser plate cutting machine to solve the problems raised in the above background technology. Utility Model Content

At the same time, some plates are of large mass, and the workers will become fatigued faster during the manual correction process, which will lead to a decrease in the accuracy of the correction. The present application provides a plate positioning device for a laser cutting machine.

[0006] The present application provides a plate positioning device for a laser plate cutting machine, which adopts the following technical solution: it includes a support plate, four support columns are fixedly connected to the top side of the support plate, the top ends of the four support columns are fixedly connected to the same placement rack, the rear inner wall and the left inner wall of the placement rack are fixedly connected to two positioning plates, the front inner wall of the placement rack is fixedly connected to two support plates, the bottom sides of the two support plates are slidably connected to the same U-shaped frame, the front side of the placement rack is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a screw rod, the screw rod is spirally connected to the U-shaped frame, the right side of the placement rack is fixedly connected to an electric push rod, and the output shaft of the electric push rod is fixedly connected to a push plate.

[0007] Preferably, the front sides of two positioning plates among the four positioning plates are fixedly connected with two guide rods, and the U-shaped frame is slidably sleeved with the two guide rods.

[0008] Preferably, a plurality of support blocks are fixedly connected to opposite sides of the two support plates.

[0009] Preferably, a plurality of short rods are fixedly connected to the right inner wall of the placement rack, and the push plate is slidably sleeved with the plurality of short rods.

[0012] 1. By setting up a U-shaped frame and a push plate, the plate is placed on the top side of the placement frame, and the two support plates support the placed plate from the bottom side. The output shaft of the motor drives the spiral rod to rotate, and the spiral rod drives the U-shaped frame to approach two of the positioning plates. When the U-shaped frame moves, it pushes the plate until it contacts two of the positioning plates. At the same time, the output shaft of the electric push rod drives the push plate to move, and the push plate pushes the plate until it contacts the other two positioning plates.
