Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to an adaptive H-beam cutting workbench. Background Art

[0002] Laser cutting utilizes a high-power density laser beam to illuminate the material being cut, rapidly heating it to its vaporization temperature and vaporizing it to form holes. As the beam moves across the material, the holes continuously form narrow slits, completing the cut. A focused, high-power density laser beam is then used to illuminate the workpiece, rapidly melting, vaporizing, ablating, or igniting the material. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, effectively separating the workpiece. Laser cutting is a thermal cutting method.

[0003] Since there are many types and sizes of H-beams when laser cutting, roller beds are commonly used as work surfaces for loading and unloading and cutting.

[0004] However, this method of loading and unloading takes up too much space, and the lateral positioning needs to rely on auxiliary facilities such as cylinders and motors. It has a complex structure and cannot guarantee accuracy. The large size and heavy weight cause serious damage to the roller bed, and the work efficiency is low, which is not conducive to improving production capacity and free switching of multiple varieties. Therefore, an adaptive H-beam cutting workbench that can solve the above problems is now needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an adaptive H-beam cutting workbench.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An adaptive H-shaped steel cutting workbench includes a workbench frame, a fixing mechanism is provided on the side of the workbench frame, a concave plate is fixedly connected to the upper surface of the workbench frame, and a fixing bolt is provided on the side of the concave plate, and a fixing nut is threadedly connected to the surface of the fixing bolt, and a clamping seat is provided on the upper surface of the concave plate, and a transverse toothed plate and a longitudinal toothed plate are respectively provided on the upper surface of the clamping seat, and the upper surface of the transverse toothed plate is overlapped with the H-shaped plate steel.

[0008] The fixing mechanism includes a right-angle plate arranged at the bottom of the workbench, and the upper surface of the right-angle plate is threadedly connected with a locking bolt, and the side surfaces of the locking bolt are respectively threadedly connected with a connecting plate and a locking nut.

[0009] Preferably, the upper surface of the vertical plate of the right-angle plate is fixedly connected to the lower surface of the workbench, and the upper surface of the horizontal plate of the right-angle plate is provided with a threaded hole adapted to the end face of the locking bolt. The lower surface of the right-angle plate overlaps the ground, and the right-angle plate is fixedly connected to the ground by a locking bolt. The right-angle plates are symmetrically arranged on both sides of the central axis of the lower surface of the workbench. By arranging the right-angle plates on both sides of the lower surface of the workbench, it is convenient to support and fix the workbench.

[0010] Preferably, the cross-sectional shape of the connecting plate is a right-angled trapezoid, and a groove for accommodating a locking bolt is provided on the side of the connecting plate, and a threaded hole adapted to the bottom end of the locking bolt is provided on the inner bottom wall of the groove. The locking bolt is fixedly connected to the connecting plate by a locking nut. By arranging right-angle plates and connecting plates on the lower surface and side surfaces of the workbench, the stability of the workbench fixed to the ground is increased.

[0011] Furthermore, by arranging fixing mechanisms on the lower surface and side surfaces of the workbench, the workbench can be fixedly connected to the ground in the factory through right-angle plates and locking bolts, so that the workbench is fixed to the ground, and static electricity is also transmitted to the ground. The suspended workbench also prevents the bottom of the workbench from getting damp and rusting. At the same time, by arranging right-angle plates and connecting plates, the workbench can be easily moved and assembled and fixed.

[0012] Preferably, the number of the concave plates is two, and the two concave plates form an I-shape, the lower surfaces of the two concave plates are fixedly connected to the upper surface of the workbench, and the two concave plates are fixedly connected by fixing bolts and fixing nuts. By arranging two concave plates on the upper surface of the workbench, it is convenient to connect and fix the two concave plates to the base on its surface and support the base, thereby increasing the supporting capacity of the bottom of the base.

[0013] Preferably, the lower surface of the card seat is fixedly connected to the upper surface of the concave plate by positioning bolts, the upper surface of the card seat is provided with two square grooves spaced longitudinally, and the longitudinal axis of the upper surface of the card seat is provided with a longitudinal card groove adapted to the longitudinal toothed plate, and the upper surface of the card seat is provided with two horizontal card grooves adapted to the bottom of the horizontal toothed plate at equal distances.

[0014] Furthermore, by arranging longitudinal and transverse slots on the surface of the clamping base, it is convenient to select different types of transverse toothed plates according to H-shaped steels of various specifications and sizes, so that the lower surface of the transverse gear plate is directly clamped on the clamping base, and the two protruding surfaces on the lower surface of the transverse toothed plate overlap with the upper surface of the workbench, so that the upper surface of the transverse toothed plate can support the H-shaped steel more stably, thereby facilitating the subsequent cutting of the H-shaped steel.

[0015] Preferably, the front and back sides of the card seat are both provided with longitudinal toothed plates, and the lower surface of the transverse toothed plate is engaged with the upper surface of the card plate. The longitudinal toothed plate and the transverse toothed plate form a cross shape, and the upper surfaces of the longitudinal toothed plate and the transverse toothed plate are both in the same plane. By providing the transverse toothed plate and the longitudinal toothed plate, it is convenient for the longitudinal toothed plate to support the H-shaped plate while the transverse toothed plate can provide position-limiting support to the lower surface of the H-shaped plate.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention realizes the natural positioning of the H-beam during the falling process without any interference with the three-dimensional cutting structure. Since no electric, pneumatic or hydraulic devices are used, the cost and production difficulty are effectively reduced. The service life is equivalent to the structure life, no maintenance is required, and there are no potential failure points.

[0018] 2. The present invention is a workbench that occupies a small space, is highly efficient, and can adapt to cutting various types of H-beams. It has a simple structure, occupies a small space, and can adapt to various H-beam specifications. It automatically positions the H-beam while loading, thereby improving work efficiency. In addition, there is no device that interferes with the three-dimensional movement of the laser cutting head, and no electric, pneumatic or hydraulic devices are used, effectively reducing costs and improving reliability.
