Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a hydraulic level exchange device for a plate laser cutting machine. Background Art

[0002] With the development of technology, in the field of laser cutting, the requirements for the moving speed and acceleration of the laser head of laser cutting machines are becoming increasingly higher. On this basis, reducing the Z-axis stroke can effectively improve the moving efficiency of the laser head. Therefore, the current requirement for the moving unit of the laser head is to have a Z-axis stroke as small as possible. The main function of the hydraulic level exchange device is to achieve fast and smooth replacement of the working platform. Driven by the hydraulic system, the material to be cut or the material that has been cut can be easily removed from the working platform and new material can be moved into the cutting area, thereby greatly improving cutting efficiency.

[0003] For high-power bevel plate laser cutting machines, due to the weight of the head itself and the need for the head to rotate at multiple angles when performing bevel cutting, the Z-axis stroke and the front bed width have a great impact on the equipment. That is, the smaller the Z-axis stroke, the narrower the front bed width can be, which can correspondingly improve the corresponding accuracy and reduce costs. For laser cutting equipment with hydraulic leveling exchange devices, in order to shorten the Z-axis stroke, hydraulic leveling exchange devices are increasingly used in the market. In the hydraulic leveling exchange devices on the market, multiple hydraulic cylinders are interconnected and need to be raised and lowered at the same time. The parallel requirements for each hydraulic cylinder and the guide structure axis are relatively strict, and the installation and debugging are difficult, which affects the production efficiency of the equipment.

[0004] Therefore, in order to solve the problem of strict parallel requirements between the hydraulic cylinder and the guide structure and high difficulty in installation and debugging, a hydraulic level exchange device for a plate laser cutting machine is proposed to solve the above technical problems. Utility Model Content

[0007] Through the above technical solution, further, the installation assembly includes a base, a guide column, a groove wheel, and a hexagonal guide rail; its bottom connecting block is installed on the surface of the base, and the guide column is installed on the surface of the base between two groups of bottom connecting blocks.

[0008] Furthermore, a groove wheel is movably installed on the inner side surface of the guide column, and its hexagonal guide rail is installed on the exchange table frame.

[0009] As a preferred technical solution, the exchange table frame includes a connecting plate, a fixed plate, a side connecting plate, and a crossbeam; the side connecting plate is installed on the bottom connecting block, and the ends of the corresponding two groups of side connecting plates are connected with connecting plates, the two groups of connecting plates are fixed by a fixed plate, and a crossbeam is connected between the two groups of side connecting plates.

[0010] Furthermore, the inner side surface of the side connecting plate is provided with a groove, and a hydraulic oil circuit can be provided in the groove. The surface of the side connecting plate is also provided with an opening, and the hydraulic oil circuit is connected to the hydraulic cylinder through the opening.

[0011] Compared with the existing technology, the utility model provides a hydraulic level exchange device for a plate laser cutting machine, which has the following beneficial effects:

[0012] 1. Hydraulic power is used to control the lifting and lowering of the exchange table. A certain number of hydraulic cylinders are set and installed on the side connecting plates. Under the action of the hydraulic cylinders, they work independently. This ensures that these hydraulic cylinders can achieve synchronous extension and contraction under different loads, and through real-time monitoring by the position detector, the detection value is transmitted to the control system. The control system starts the hydraulic cylinder, effectively meeting the requirement that the exchange table always remains horizontal, avoiding the tilting situation that makes it impossible to exchange. The utility model also ensures that the processing tables of the front bed are all in the same plane, meeting the shortest Z stroke during processing, and can also effectively make the overall width of the front bed relatively narrow, reduce the span of the beam, reduce the risk of sinking in the middle of the beam, improve the cutting effect, and reduce the variables when the equipment is cutting.
